Before that, the flight monitoring and commanding hall of Daxing Airport had never been opened to “outsiders” like me.
I walked along a corridor that seemed as if I couldn’t go to the end. I silently followed Hu Fen, a system engineer, and had no time to admire the surrounding museum-like decorations—for example, I found out later that the walls It’s full of all the airports you can name in the world and their floor plans.
The sound of breathing is quiet and legible all around. At this time, no one was willing to speak, as if there were any noises, a group of people rushed out of the door of the command hall in front and carried us to some confined room.
“Here, I want to dock with them (monitor).” Hu Fen walked in first, and I hesitated for a moment across the translucent glass, and finally stepped into the largest digital operation of Daxing Airport. space.
No photos are allowed in the command hall, only one can be placed outside
In fact, until the moment I stepped into the flight control and monitoring hall, I still didn’t realize the significance of “big data” to this world’s largest single terminal project.
However, when a surveillance screen larger than the IMAX movie screen suddenly occupied all my vision, this feeling is very similar to looking up at the top of the mountain and suddenly being hit by a boulder rolling down the mountain. Head.
A netizen once described Daxing Airport as a spacecraft about to rise. Standing todayIn front of this giant screen, I suddenly felt that this description was very clever, because the command cabin in science fiction movies should look like this.
Standing in front of the screen, you can peek into the entire data starry sky.
Please use your imagination
A huge map of China is tiled at the most obvious position on the screen. All online flights are clearly delineated on the map through two points and one line, showing a radial texture like a girl’s scattered flower;
Each second, the flight operation information of each finger gallery is undergoing subtle and firm changes. 79 near seats are accurately “dotted” on the Phoenix-shaped floor plan of Daxing Airport. Switching back and forth reminds us of the exact time of departure and arrival at each seat …
After staring for a long time, the real-time data flashing and scrolling on the screen seems to be jumping and flowing above my brain. Everyone present is just one of them.
However, Hu Fen seems indifferent to all this.
He was carrying a backpack and lying in front of a computer in a very uncomfortable position, helping the monitor to check for bugs in the video operating system.
“It seems that the monitoring images of several bayonets cannot be adjusted.” A uniformed brother dragged several times on the computer, but couldn’t open the monitoring image of the underground parking lot.
“Don’t worry, there are still several subsystems and bayonet videos in the process of being accessed, which has nothing to do with the system itself.” He knew that the needs of the monitor this time were the same as the previous hundreds of calls. Solve a problem that only time can solve.
In the hallway leading to the command hall, the plans and construction plans of the world ’s famous airports are suspended
All the connection and integration tasks of cameras and video command platforms at Daxing Airport are under the full control of a security video company where Hu Fen is located.
The work they have to do is to pack all the information of more than 10,000 cameras in all corners of the airport into a “box”, and then share them with more than 30 different lower-level operating platform manufacturers and different levels according to their permissions. User. Of course, we also need to customize the new requirements put forward by these users at any time.
This is definitely not an easy job.
4 channels, 8 channels, 32 channels … With the continuous increase in the number of video access channels, the requirement for the concurrent operation capability of the entire system platform has increased exponentially; at the same time, you must respond and meet at any time Some “wonderful ideas” from airport staff.
And Hu Fen has only one thing to do: respond to the needs of users, hang up and down in the building, and be on call.
Now, I find that the color of most cameras on the screen is “bright”, and only a few orders have been placed. This means that Hu Fen and his colleagues have gone through the most difficult period.
“The airport is now officially operational, do you have to fight back home?” I thought it would be their last time here.
“Go? It’s too early!” Like any system engineer stationed at the Daxing Airport site, Hu Fen can always pull out a large stack of documents or a laptop from his bag and write a new requirement on the spot. .
“Six drills have eliminated a lot of problems, but it is still in the early stages of operation. Many data tasks are still being perfected, and the system docking is still in progress. Here. “
“It is estimated that the car must be scrapped before it can go.” He pointed to the Kia K2, which had scratches all over his body.
I learned a proper term in the security industry-“accompany operation” in the day when Hu Fen stopped communicating with airport staff for almost a moment.
From the day when the airport’s main project was completed, to the current formal navigation operation, both the hardware facilities and software system engineers need to continue to “guard” the airport here. Even if the entire project operation enters a stable period in the future, there will still be 4 engineers on duty 24 hours a day to accompany the airport for a year.
Engineers are special jobs that run through the past and future of Daxing Airport and accompany the airport to “grow”.
The AOC and ITC buildings, about 2 kilometers from the airport terminal, are completely ordinary in appearance and difficult to navigate. The driver turned around the periphery of the terminal three times. I found it in the circle
When the focus of the public is all on the “miracle” of the main building of Daxing Airport, who can think of an ordinary 6-story office building less than 2 kilometers away from the main building of the airport, this is the project in the big data world. Main battlefield ——
Daxing Airport Command Center (AOC) and Information Center (ITC).
The two black buildings connected by a corridor are the beginning of the article that shocked my entire video surveillance command hall.
Among them, the ITC Information Center is the “machine room” of Daxing Airport.
As long as it is within the new airport, more than 60 core equipment of weak electric information systems, including the core computer rooms of the three major operators, are all gathered in the ITC computer room.
The key point of the weak current system is that it carries all big data tasks involving airport networking, computing, storage, and information interaction.
Another building, called the AOC Command Center, is the core of the entire new airport ’s operational control, command coordination, and emergency response. It is also a veritable “data operator” at Daxing Airport-
All information under the jurisdiction of the weak current system, such as video data collected by the camera, must be “played” here.Reorganize “.
In other words, all the secrets related to internal and external communications, networking, and data dispatching operations are hidden in these five 5-story buildings.
Without support here, the plane would not be able to fly out.
However, these things that have been running in the background in an orderly manner have no ornamental value, and they will never be deliberately searched or watched. Just like the engineer who carried them back or resisted to the scene, they will not be greatly appreciated. Discovered and remembered by some.
But it just made me more curious-
What kind of people support the data scheduling and machine operation of the airport’s intelligent section?
“Okay, let’s go downstairs and take a look at our own” Old Nest “!” Leaving the command hall, I offered to see where they worked. Hu Fen hesitated for a moment, but finally agreed.
Smart, supported by people
In fact, Hu Fen’s colleague Liu Yanqi (pseudonym) has already “warned” me in advance. If I have been to the command center of style, and then go around where the engineers stay, it is estimated that there will be some disillusionment.
But what I see now just let me, as a science and technology journalist, enter the unusually familiar world.
In the data information control center, which is only 1/3 the size of the command hall, the “footprint per person” is indeed much smaller. Although it is a bit crowded, everyone can walk back and forth and exchange a few sentences with each other. The atmosphere is obviously “easier” than the command hall.
The engineer sitting at the work station stared at a few lines of code on his laptop with almost no blink of an eye; while in front of the big screen, three or two engineers stood together, fingers tapping on the screen The CPU capacity data chatted cheerfully.
The Data Control Center is now the new “nest” for computer engineers
The responsibility of the data information control center is actually simple and clear: to ensure the normal operation of all servers, video size systems and front-end hardware equipment in the background. Therefore, once an external unknown cyber attack is detected and intercepted, the red warning sign on the screen will flash extremely dazzling.
“Various vendors have basically met here, with servers and cameras.”
Compared with the monitors in the command hall, engineers are obviously more proficient in system operation. The speed at which an engineer fetched video photos of each airport bayonet reminded me of “the appearance of Depo when shuffling poker cards”, inexplicably showing a handsome gesture.
However, this task will take 7 hours.
“Although the smell is still not very good,” Liu Yanqi wrinkled her nose. “But this place is much more spacious than our previous place. Everyone was originally nesting on the roof of the building, where there were many people and small, whole People ca n’t wait to curl up together. ”
The “rooftop” that Liu Yanqi refers to is actually an ordinary office with fairly complete facilities.
However, before entering this room, we need to go through a narrow corridor and a computer room with a huge roar of servers. soundSound can penetrate walls without interruption, continuously bombarding our eardrums.
With the push of a door, except for a few engineers, the room is almost half-empty, leaving only large pieces of cluttered wires and hardware equipment piled on the table and the open space.
Hu Fen quickly caught up with an engineer. In the engineer’s low sigh, we learned that due to the delay in access to the optical fiber, the docking task of a certain system must be delayed for a period of time.
“The line is down, we can’t do it anymore.”
When the “serious” information center downstairs wasn’t open in early 2019, Liu Jiqi remembered that the three of them would share a workstation. Everyone used their legs as a table to knock together the code, and they really felt bored, so they went outside to open up No one on the round table is willing to inhale the carbon dioxide exhaled by each other in a day cycle.
Earlier, that is, in 2017, when the airport’s main project was just completed, and the video platform and other systems needed to be officially accessed, Hu Fen, Liu Qi, and the company’s entire Daxing project team were temporarily built by the airport. In the model room, we started to build and debug the system.
The specific location and environment they have long forgotten, just remember that drinking Northwest wind to knock on the code feels really “sour.”
“There were no decent roads two years ago, and there were earth pits everywhere. When the wind blows, it will be sprayed with sand.” At that time, Daxing infrastructure was still in progress. Completely “paralyzed”, Liu Yanqi, who has to come to the airport for docking needs every day, has developed the habit of recording a road map with a pen. However, even this is still not a trick.
“The first day was easy to write down, the next day I really wanted to cry because I was dug up again.”
The roads around the airport’s main body were all pits two years ago
As a girl, being a front-end engineer in the security industry where men are the absolute main force is a great thing in itself.
When Beijing Jiaotong University joined the company in 2017 after being graduated, he was “thrown” into the “barren land” of Daxing. Liu Yanqi often fell into a state of madness-
Knock it on the side of the road and “bear it”, and the anxiety caused by a series of trivial and common problems of the computer, and the sadness of being scolded by users from time to time, runs through her throughout 2018.
“All the large and small schemes of Daxing Airport must follow the process, how to implement it, and what impact it will have. If there is any problem in this step, how can you smoothly return to the previous step …
A simple solution may need to be changed more than 30 times. “
After the airport is officially opened, in order not to delay the normal operation of the airport during the day, the entire team where Hu Fen and Liu Yanqi belong can only work at night. More precisely, the project stipulates that the actual implementation and operation time is from 12 to 3 in the middle of the night.
And there are as many as 70 R & D and customization projects taken over by Liu Yanqi, each of which requires her to participate in testing; once testing, you need to pull the R & D department to “accompany” the airport.
“In fact, we have always been very nervous, because according to the planned 100 million passenger throughput of the airport, you have no idea how much traffic the entire video command platform needs to carry after the airport is fully opened.
We can only test continuously, one person, one hundred people, one thousand people. The system needs more robust stability and stress tests. “
In order to be afraid of insufficient system redundancy, before the actual commissioning exercise, Liu Qi and the system developers did a lot of stress tests. They simulated the picture from thousands to thousands of times in the laboratory environment. The amount of concurrency and repeated calculations of the results hundreds of times.
But in reality, no one can predict the end result.
“We don’t know how many times we received task instructions to troubleshoot unstable functions in the middle of the night. In fact, everyone seemed confident on the surface, but every time they only prayed in their hearts: Can they be faster, faster? Quicker to resolve it. “
For engineers, the office is the “battlefield”
The “side-by-side” acclaimed with Daxing Airport is the Daxing Airport Expressway outside the door, which is called “Xinguomen First Road”.
Because this seemingly ordinary highway has been added with unprecedented intelligent application attributes such as “deicing and melting snow”, “electronic sand table” and “traffic warning”, the mechanical and electrical engineering of the entire airport high-speed network has become more The essential.
In the beginning, according to the plan, it took about 1 year from the survey to the final completion of the entire mechanical and electrical engineering. However, due to too many uncontrollable factors, including obstacles such as delays in demolition, the actual system installation and commissioning time for mechatronics engineers is only half a month.
There are three major systems for expressway electromechanical systems: monitoring, toll collection, and communication. Among them, Qianfang Technology, which won the “monitoring target” in mechanical and electrical engineering, faced with awkward realities when entering the market:
All the cabinets have just been completed, the server has not been installed, the operating system has not been installed, the switch has not been properly adjusted, and the electricity has not come.
According to R & D engineers Zhang Guibin and Li Dianhong, everyone basically does not go back to the project department until 1 am every day, and never goes back to the machine room at 7 am to adjust the machine.
Especially the first three days of the opening on July 1, 24 hours a day, never rested.
All three meals are settled in the highway monitoring hall
It’s not just the scorching sensation of time.
When these software engineers entered the site, they found that there is a serious problem in the design of the computer room-no air conditioning.
Since mechanical and electrical engineering includes three major sections, this means that the three systems have different servers to support the system operation. These servers are all housed in a computer room.
Qianfang Technology is mainly responsible for “monitoring”, and “charge” and “communication” are controlled by two other companies. Obviously, if engineers of all parties go to debug together, the server is likely to hang.
From the perspective of human physiology, engineers work more than 5 hours in a room with a room temperature of up to 40 degrees Celsius.
So after unanimous negotiation, engineers can only “shift into the sea of fire” for debugging, and each team can only work for about 4 hours at a time.
In addition, because there is no internet connection, they need to debug each one after each server is connected, and adjust one to one.
“We can only adjust it in the computer room, because the outside network is not ready yet. In fact, the lobby is also hot (no electricity), and it is also around 40 degrees. So it is the same everywhere.”
The burning sensation brought by the high temperature makes them feel like they are stepping on a ball of cotton, feeling that they are about to float to the sky. Even if the machine in front of the ear keeps banging, it won’t hold back the dizziness that the blood rushes to the brain.
“The engineers at the site said they seemed to be dreaming. But the time was too limited. They can do a little more. We ca n’t do it until we open the train.”
Finally, all equipment was commissioned a few hours before it opened to traffic on July 1, 2019.

A corner of the machine room
This is the first time I have a real sense of “China Speed”. Disciplinary like a military and a team spirit of strong teamwork, almost universally exist in the engineering team involved in the construction of Daxing Airport.
The technology and machines that win the attention of the public and win the attention of the public are actually the moment when the life ends when the plug is unplugged.
Just like all the face recognition gates you see at the airport, they actually need to be resisted by human flesh into the terminal. It sounds like some irresistible violations.
In your opinion, how long does it take for a face recognition boarding cabinet to enter the airport gate and finally arrive at the boarding gate?
The answer is more than 10 hours of human flesh handling.
Every face device you see needs to be transported at the airport
Since some people only hold Class II credentials for one-time entry and exit to the airport, Ruiwei, a technical engineer who supplied more than 300 face recognition gates to the terminal, can only come out of the office once he has entered the airport every day .
Therefore, this group of mature engineers is carrying a sack of bread every day, carrying the machine into the door, and doing it overnight.
“The inspections are so strict that even water and food are restricted. At that time, the stores were not renovated, and there was basically no place to eat and rest.”The project of Xing Airport made Liu Gong always think that he must drink water and have a good time.
It’s hard to imagine that much of the time here is actually “wasted” in the process of machine handling.
Like humans, all machines have to queue up for security. However, even the machine needs to grab the most favorable position and time node in the limited construction period.
In the early stages of the entry of a large number of equipment manufacturers, all machines were crowded in front of the only “commodity inspection” entrance on the first basement level of Daxing Airport, waiting in line for stricter review and proofreading than humans.
In the first inspection, Liu Waixiang and his team spent a total of 6 hours under the ground, and the next day exceeded 7 hours. In the long queue, his ringtone never stopped.
“I can take over 60 calls and coordinate the tasks of the owners and other manufacturers are with me.”
The combat headquarters of Daxing Airport is known as “resolutely popular” in the eyes of all participating hardware equipment manufacturers. An emergency order is usually given, leaving engineers with only 24 hours to operate.
“The airport may tell you that night that you must complete the installation and commissioning tasks of the A Finger Corridor the next day. We can only coordinate a dozen people immediately that night, and guarantee that the delivery will be completed before 12 am the next day. Command. “
However, in many cases, the second-class certificate cannot be approved in time. In this case, if the shift engineer is not available, an emergency task will cause the engineer inside the airport to pick up the equipment again, pick up a screwdriver, and go to each designated finger gallery.
What impressed Liu Waixiang most was that in July, an emergency mission was just issued. There were only six brothers on the scene.
“The brother didn’t say a word at that time, immediately got up from the groundHere, the uncles carried the equipment, the two went to screw the screws, and the two went to pull the trailer. “Liu Waixiang remembers that everyone has reached a glance and knew how to divide the work.”
When he told me this experience, at first he always changed the word “brother” that he blurted out to “colleague”, but he couldn’t help but change his name to “brother”.
Although compared to the steel beam riggers and construction workers who need to go shirtless, the engineers’ battlefield is a bit dull and boring.
But just like Liu Waixiang’s description of eyebrows dancing, no matter where the “fighting” is, everyone always has such a “fighting side by side” friendship.
If you have n’t spent the night together, you have been smashed by your equipment to the toes, and you have been scolded by Party A. This kind of friendship will not happen.
Although the excellent daylighting design of Daxing Airport is praised, when the designers considered the daylighting problem, they might not consider it, which would have an impact on the intelligent identification equipment that only arrived in the middle and late stages of the project.
Actually, because the position and intensity of the sun’s rays change within a day, it will directly interfere with the accuracy of face recognition. The system commissioning engineer needs to test and adjust hundreds of devices one by one at different times during the day. Once again, and this is a job that requires both physical and mental energy.
Liu Waixiang can’t remember how many tests he and his brother have to do each day. Whether it’s the day of the big sun or the light rain, they all trot as much as possible to take into account one more machine.
“If there is a problem during the use of the airline company during the test period, the time limit for solving the problem is 30 minutes.
“30 minutes?” I don’t believe it,
“Troubleshoot the problem within 30 minutes, and then fix it. Failure to do so will affect the flight of the day. If the flight crew finds that the equipment is not available, it will report immediatelyNotify the airport and the airport will blame, this is a vicious circle. “
When Liu Waixiang waved his arm unintentionally, I glimpsed a lot of scratches on his arm. In the end, he even showed me his hands. The swollen palms of the purple proved that he should also be assigned to many tasks of moving the face recognition gates.
However, when I asked if I could take a picture, he was slightly embarrassed and refused.
“It’s really nothing to say, if it hurts, then we are too weak.”
In the process of coordinating the entire project, no matter who it is, Liu Waixiang will call him “Liu Gong”. And whether it is “Liu Gong”, “Brother” or the size of the wound on his arm, he is regarded as an “honor”.
Or, another kind of “medal.”
Unprecedented system engineering
Daxing Airport has been in operation for only two months. In the overwhelming publicity, “intelligence” is the strongest label affixed to this airport project.
However, the so-called “one face travels through the airport”, “the seamless service experience of superfast speeds under the full coverage of 5G airports”, “the fully automatic tracking and control of luggage” and “smart airport expressways” play a decisive role behind Not all are high-tech in the literal sense.
More than 10,000 cameras scattered throughout the airport, but rarely found, with nearly a thousand face recognition devices installed, 5G base stations deployed around the airport, optical fibers buried under the road and 24 A large telecommunications room that is full of hours …
Everything that is “smart” is more concrete but seldom attracts attention.
In fact, the coordinated operation from the top to the bottom is the fundamental reason why you can “walk the airport with your face.” Therefore, Daxing Airport is also an oversized system project with the largest number of computer software and hardware engineers participating.
The intelligence that Daxing Airport wants has placed unprecedented demands on all the computer engineers involved in the construction. And these are experiences that they cannot learn from and share with any existing airport.
“Cross the river while feeling the stones. I used to think that this was a bit of a pretense. Now I understand the project of Daxing Airport.” Zhang Guibin, who has been working for many years in mechanical and electrical engineering, feels that this project is like a class back to school. .
Charging, monitoring and communication are now the “big three” in high-speed electrical and mechanical engineering. Because with “intelligence” becoming the standard for road construction, many related traditional construction projects will no longer exist.
For example, “toll booth.”
As early as May 2019, the Minister of Transport stated that before January 1, 2020, the toll stations of provincial highways across the country will be cancelled. Instead, there is a non-parking electronic toll collection system called ETC.
This system is undoubtedly part of the mechanical and electrical engineering of the Daxing Airport Expressway.
In addition to the important changes in the construction of toll stations, the information transmission method of road surveillance cameras and backstage has also jumped from the original “direct optical cable” wired transmission to “wireless or 4G transmission”; all videos will be double-backed up Part of it is local and part of it is transmitted back to the private cloud.
As this project has increased its reliance on big data, cloud computing and other technologies, this has also enabled a number of technology companies such as Huawei to play an important role in it.
For example, all blade servers (also called blades) in the machine room of the Daxing Expressway are provided exclusively by Huawei.
This is an important component of a server cluster. It can be said that the entire road monitoring system is built on the blade machine, and all video data also needs to run and flow on the blade machine.
A blade contains 4 CPUs, each “blade” is equivalent to a system motherboard, 8 blades are a frame, and one frame is equivalent to a small server. This is such a blade server, its computing power and speed are much higher than an ordinary server.
“Although this is very common in their big data centers at Ali Tencent and Baidu, this is not used for general high-speed projects. Daxing Airport is the first one.” Li Dianhong had to admit that this is indeed the best one Hardware configuration.
ButThe addition of more hardware equipment and software technologies not only increased the magnitude of data and engineering complexity suddenly, but also caused his overall workload to be several times greater than previous airport projects.
“In the past, we dealt with infrastructure, communications, and charging standards a lot, but this time we used a lot of new equipment and came up with many new problems. We had to find more than two technology companies to solve together. / p>
On one occasion, the storage module for a surveillance video at an intersection was “down”. Li Dianhong called the camera company, the video platform service provider, and the company technicians who provided the storage switch, and everyone worked for an hour.
“We originally called the camera and video platform people, but later we checked the video together and found that this involved storage configuration. In the end, we could only call Huawei people because they provided storage switches. “
The significance and presentation of Daxing Airport as a system engineering is not the same for every engineer.
Liu Yanqi remembers that many people who have done airport projects came to tell her that they have never seen an airport with so many plans to write:
“The simplest job is to do the monitoring platform itself, because the protocol is relatively mature, and it is enough to interface with the country. But the most troublesome is that many subsystems under the platform are built with the latest technology. , Which haven’t really been implemented before. “
For example, in order for the monitoring center to confirm the precise location of each camera at the airport, the entire video monitoring system needs to be “superimposed” on a detailed plane map of Daxing Airport.
Yes, that is to insert the more than 10,000 cameras one by one into the “Big Phoenix” and the surrounding open space precisely according to the geographic location.
< / p>
In order to avoid illegal use of pictures, the camera map is mosaicized
Of course, they also need to do it, so that all the monitors can drag the mouse or double-click on a camera to see the video of the mount where the camera is located, and get real-time personnel trajectory and alarm information.
The difficulty of system integration is just around the corner.
Liu Yanqi docked with a graphics provider who provided map location data for three months. The plan has been modified more than 40 times, but the command center will continue to report the existence of “Personnel trajectory on the map disappears” and “Video on the map Big and small problems such as “can’t retrieve it”.
“Now it has been much better after the official operation. The test period before the airport’s overall exercise is a frequent problem stage. All the technology vendors involved in the construction are very anxious because of the ‘conflicts’ between the various modules of the system. ‘Continuous. “
For example, in order for each system to have the ability to “monitor each other”, even if the video platform comes with security software, it needs to install 360.
But sometimes the two are not compatible; or as soon as 360 goes up, some hardware won’t run.
Therefore, even though the airport has undergone 6 operational drills, most of the smart functions are now online, but given that Daxing Airport is still in the early stages of operations, the flight has not yet completed the initial stage of the “big move” operation. System engineers Still nervous, in a state of readiness.
In the AOC building, several joint commissioning rooms have been set up for various manufacturers to coordinate and debug. Among them, the low-voltage joint tuning room is always crowded with various hardware equipment and video platform manufacturers, and it can reach 30 or 40 people at most. Liu Qi is one of the regular customers.
“Everyone is crowded inside. Sometimes when I want to find someone, I turn around and find out that the other party is also there, so we just say Hi.” Liu Yanqi joked that everyone was in a state of “walking up and down” .
“You don’t know what will happen next, or how many more problems.” Hu Fen and Liu Yanqi have carved “caution” into their bones and told themIn other words, there is never a 100% number concept.
“There is no such airport in the country or the world with such construction experience, nor any suggestions for reference. We cannot predict what will happen in the future, we can only determine what all manufacturers can do with each other:
Encountered a problem, and then solved it together. “
In the face of this group of engineers who never give a definitive answer, I have a question: If an error really occurs, will it affect the normal boarding and personal safety of ordinary people like us?
Their answer was finalized once: no.
The “intelligence” we can feel is just to get into the aircraft more quickly to find a seat; erasing the “intelligence” just returns us to the normal process of queuing for paper tickets today. go with.
“Assuming that a serious accident really caused the video platform and face recognition system to go down, it may just be a worse travel experience for passengers, but this is definitely not a necessary condition to determine whether they can successfully register.” Hu Fen insisted The importance of data service providers must not be overstated.
In other words, “intelligent” is more like a safe redundant backup of the operating system of Daxing Airport.
The so-called “smart airport” refers not only to the real flow of data after the system is opened, but to create a friendly data environment where various hardware and systems can use each other, verify and supervise each other.
Therefore, for a truly successful system project, it is impossible to “let go” and let a system take control.
The most common and safest method is to use a system or two or three other parallel or subsystems to further confirm the information after a system obtains certain information.
Like a self-driving car with multiple layers of safety and redundancy, multiple sensorsIt supervises with high-precision maps, and is supported by physical collision avoidance equipment and fatigue driving early warning system.
“It’s like our video platform is hung up, but the subordinate platform should still record the video. What information should be collected, what information is collected. Our hung up, nothing more than restarting another platform and another service. “
“One of the greatest advantages of Daxing Airport as a system engineering is the establishment of a more complete system of mutual verification.”
The joy of an engineer is simple
During the entire long visit, there was only one problem that put all the engineers I met into a consistent awkward silence:
Do you have any fun projects for Daxing Airport?
It turns out that the “interesting” in the eyes of technical engineers is somewhat different from the “fun” of ordinary people like me.
From the particularly young photo on the badge, Zhang Guibin, who has worked for Qianfang Technology for more than 13 years, is actually familiar with the troubles and novelties encountered in the project.
For example, he has repeatedly witnessed the “spectacular” scenes in which the two construction parties were in disagreement in previous projects.
But this time, the “server boiler room” in the airport highway lobby gave him new insights.
“I remembered something fun.” After scratching his scalp many times, he suddenly remembered a clever way for engineers to find their senses in the dizziness brought by 40 degrees high method.
When debugging the machine once in July, he stumbled upon the fact that the door of the machine room was opened just north, and the door was outside the corridor, and further north was a fire-fighting ladder. There was a small fire behind it Door …
“Guess what, does this make a north-south pass!” He patted his thigh in excitement,
“It was so hot at the time that I couldn’t get in. Only a few doors could be opened to get a little cool breeze. Everyone said it was a good idea!”
“… hahaha.” I can only say that I am amused by the unique happiness of engineers from the heart.
Thousands of engineers at the completion ceremony
With high-intensity workloads and anxiety-dominated situations, any external cause that can cause subtle changes in mood will become a source of triggering their happiness.
Liu Weixiang, Ruiwei, once he can breathe a little bit, he likes to walk around each finger gallery, and then silently backs up all the shops selling food, so just wait to open the shop. A delicious meal.
“Brothers are sitting on the floor and eating some bread together, thinking about when to take them for a good meal.” Now that he has sailed, his wish can be fulfilled.
Today, as “accompaniment operations” engineers for the face recognition gates, they still need to “spot” around the boarding gates like a plainclothes policeman.
Although they sometimes get the eyes of passengers, most of the time, they find it interesting to observe the expressions of passengers when they brush their faces in silence.
“A lot of people are arranging their hair against the small frame that brushes their face, and they feel beautiful. However, the screen you see is actually beautiful.” Liu Waixiang suddenly exposed the “poisonous tongue” By nature, he immediately emphasized that the information played back was without any filters.
When a passenger smiles while brushing his face, Liu Waixiang sometimes laughs stupidly. Without a work permit, he will really be considered a tracking fanatic.
“In this case, we usually default directly, should they think the machine is good?”
“Daxing Construction Seminar” appeared in the airport terminal
Whether in the flight command hall or in the data control center where engineers gathered, Hu Fen always looked serious and introduced the business with a scrutiny and a stark contrast with the lively Liu Yanqi.
On the issue of “fun”, he also likes to “perfunctory” me with up to 10 “satisfying user needs” and other similar jargon.
Just when I finally decided to give up questioning, after sitting in the Kia broken car that had followed them for 70,000 kilometers, Hu Fenchang sighed in his seat, the tension felt instantly. Disappeared.
The two engineers started to joke about the shape and color of Daxing Airport. This is an important topic that they have been discussing tirelessly during the project:
“Like a pie star? Some colleagues say it looks like octopus, and some people say it looks like a drone, but don’t you think it looks like a dendrite at the nerve ending …”
Hu Fen, who arrived at the terminal lobby, has completely evolved into another “version”.
He jumped, more excited than those uncles who came to check in, pointing at the overlapping elevator building at the entrance of the terminalLayer urged me to take a picture quickly.
“The first must-have location in the circle of friends! Take a picture!” Then he took us to the next check-in destination at an extremely fast pace. “
“Here and here, if you do n’t see the national flag in the distance, you have to check in!”
“Wow, the location of this restaurant is just right for the national flag. It will definitely be hot. Someone will definitely enter it for how much it is. %% * # @ ……”
I must not say from my heart: The joy of engineers is as simple as that.
“In fact, we haven’t been here for two years. Two years ago, the one that was still bare here was a shelf, without any beauty at all. It was surrounded by soil, and every step we took was suffocating, which caused us to practise suffocation. “Liu Yiqi still remembers the dirt road outside the airport.
However, watching a building stand up in two years, and then watching the building from a pile of steel bars to a fuller and more three-dimensional structure. Fen and Liu Yanqi did not feel any surprise.
“I just have the feeling that the child has finally grown up.” Liu Yanqi took a picture of the national flag flying in the distance, and she felt that feeling was complicated and beyond description.
“How to say we also participated in the construction of the airport. Although there is only a small part, it has a feeling of breaking my heart.”
“Are there any things you want to do after this project is completely finished?” I remember correctly, this should be the last question I asked,
“What I want to do the most? What I want to do is bragging about everyone when I say that Daxing Airport is part of the construction of me, haha.” Because the roar was too loud, several tourists passing by frequently looked back and waited.
“We participated, and so did they.” She pointed to the sweepers who were cleaning the floor. “But to be honest, no one cares about this. Everyone has no name,Don’t care if there is a name. “
I didn’t know what to reply, so I took a picture of this uncle.
Finally, let us pay tribute to every builder who participated in Daxing Airport.
Postscript:
The interview with the engineer who wants to be an intelligent project at Daxing Airport stems from a very common finding: I saw a black fingerprint on the bottom of a very ordinary face recognition gate (too obvious, I do n’t know how to mess with it) Up).
I thought at the time that this fingerprint was accidentally picked up when it was being carried. So who will move it, who will debug it, and who will start the face brush program?
As a science and technology journalist, I used to focus on the technology and product level, but when I saw the so-called “black technology” report on Daxing Airport, I just felt more and more tired.
Sometimes when we are overly advocating technology, we may overlook something from the heart about human nature. This is one of the points I want to convey to the outside world by describing the status of the engineers involved in the airport project.
Many times, people are intoxicated with a large number of wide-angle lenses, feeling the amazing beauty of a huge project, but never know or say how to understand the people behind this project.
This time, due to conditions and time constraints, we can only focus on writing the work experience of a few specific project engineers, which is also the omission of this article. In fact, I just want to remind everyone that there are too many people involved in the construction of Daxing Airport project that deserve our respect and be remembered.
There are 100 people behind every machine. The essence of the beauty of technology lies in people.
