A few days ago, I wrote a posting “Tencent Tiny OS combination NB-IoT, is it worth the programmer to try?”, coincidentally met the founder of Tiny OS, Wang Lichao, and talked very much.

Not only found a lot of common friends, but also after checking the latest code of Tiny OS, I found that many problems have been changed before.

When the sighs are awkward, I feel that the previous articles are just talking about the Internet of Things from the side, not too enjoyable. Simply by means of this article, let everyone thoroughly explain the Internet of Things.

Evolution of the basic logic of the Internet of Things

Basic Interpretation

Using sensor, GPS, laser scanner and other information sensing devices, through special transmission modules (such as NB-IoT, Wi-Fi) to achieve people, people and things, things and things Connections (Anything, Anytime, Anywhere) at any time and any place for information exchange and communication to realize a huge network system that intelligently identifies, locates, tracks, monitors and manages.

The concept of “things” is upgraded

The concept of “thing” in the Internet of Things originally refers to a device equipped with RFID or other sensors, but with the escalating trend of the intelligentization of the Internet of Things, the current ‘object’ can be included in the “Internet of Things” to meet the following conditions. Range: (1) data transmission function; (2) storage function;3) CPU; (4) a separate operating system; (5) a dedicated application; (6) a communication protocol that follows the Internet of Things; (7) a unique number that can be identified in the wide area network.

Evolution of the technology stack

In the definition context of the Internet of Things, the Internet of Things was generally divided into a perception layer, a convergence layer, and a transport layer.

But recently, through the development of a period of time, people have found that sensor data is transmitted in one direction, and it is impossible to realize the appeal of smart networks. Therefore, IoT terminals require specialized chips and operating systems. Therefore, there should be a system layer of the terminal between the sensing layer and the aggregation.

And before we “ giants covet but Can not be dyed , IoT database has been introduced to the air, as has also been introduced, the traditional database design and the demand for massive data storage in the Internet of Things era does not match, the Internet of Things requires a special time series database for data storage.

This way, the data value and the integration of artificial intelligence and big data will be more fully utilized to produce a more pronounced fission effect.

It can be said that the current IoT technology stack has captured almost all the most advanced technologies: 5G, IPv6 technology (to accommodate the terminal capacity of the Internet of Things), chip technology, operating system, NB-lot, time series database, cloud Calculation and so on. It can be said that it is a “big master” of various technologies.

Sense layer: Sensor technology, RFID technology, QR code technology, MEMS, audio and video capture technology

End system layer: includes IoT chips such as MCU and IoT operation OS

Convergence layer: sensor network self-organizing network technology, ZigBee, UWB, Bluetooth and other short-range communication technologies, Wi-Fi, LAN and other local area communication technologies

Transport layer (network layer): Internet, telecommunication network, 2, 3, 4, 5G network, NB-IoT, LoRa, NGN, and other wide-area communication technologies

Data storage layer: is mainly time series data such as Tdengine and OpenTSDB, etc.

Application layer: Cloud computing, data mining, AI, high-end software

Characteristics of the Internet of Things

The essential characteristics of the Internet of Things are summarized as follows: First, the “object”, that is, the “object” included in the Internet of Things must have the function of automatic identification and object communication (M2M);

The second is “link”, the network is born out of the Internet, the essence is the transmission of information;

The third is the “net”. The Internet of Things not only provides connectivity between objects, but the network itself and the cloud computing itself also have the ability to handle big data.

At the same time, the Internet of Things evolved with the fourth feature and “intelligence” characteristics, that is, the network should have the characteristics of automation, self-feedback and intelligent control.

Evolution of National Policy Directions

After 2012, the Ministry of Industry and Information Technology released the 12th Five-Year Plan for the development of the Internet of Things. In 2015, the scale of China’s Internet of Things industry reached 750 billion yuan, and it continued to maintain a compound annual growth rate of about 30%.

In 2016, the Ministry of Industry and Information Technology released the 13th Five-Year Plan for the Internet of Things industry. Comparing the two plans, we can see that there have been some changes in the definition of key technologies.

Two of the biggest highlights: First, the IoT operating system is listed as one of the key technologies, and the second is to integrate the Internet of Things with the mobile Internet and big data technology.

It can be said that this 13th Five-Year Plan is a forward-looking guide to the development direction of the industry. Tiny OS+ Tencent IoT Hub; Lite OS+Huawei Cloud and other products are the products of this trend.

New trends in the development of the Internet of Things

1. Spillover effect is heating up: the concept of “Internet +” isIn 2014 began the popular Internet Conference in Wuzhen, the author of “On the article of Jianwu Town, it can be said that the Internet was subverted and reconstructed in other industries after more than 40 years of birth. However, the current Internet of Things + Internet of Things, mobile Internet of Things, smart cities and other industries have begun to take shape. The key logic behind it is that the Internet of Things terminals are dozens of times larger than the traditional Internet industry. The collision effect between massive data and artificial intelligence has already made people feel the great power of the Internet of Things.

2. IoT network intelligence: As mentioned above, the latest IoT terminal should be a smart terminal with OS, which can adjust itself according to external feedback. The IoT network that simply sends sensor data is difficult to create new scenes and will gradually be eliminated.

3. Standardization of open source: At present, many IT companies are vigorously promoting their own open source framework. In fact, the current open source framework dispute is the standard dispute 20 years ago. For example, the Google Deep Learning Framework TensorFlow has become the industry standard for artificial intelligence. Whoever masters the most popular open source projects, whoever has the right to speak, will lead the industry’s development direction.

4. The whole stack controls the trend: At present, all the giants are still in a certain segment, but in the Internet of Things era, the giants are basically based on cloud computing technology, and strive to the entire Internet of Things industry. The chain is fully controlled.

The competition strategy of the current giants

Tencent: User Experience Seeker

It may be the blessing of the WeChat portal. It can be said that Tencent Cloud’s user experience is the best, and registration is very simple.

Tiny os is the youngest of many domestic IoT operating systems, but their iteration speed is the fastest. After communicating with the founders of Tiny os, they have a dedicated team to collect the Issues on GitHub and go one by one. Analyze the upgrade.

For example, before their timer, it is impossible to set Interval, but oneIn the new version after the week, this function has been added, and the iteration speed is amazing. Therefore, Tencent’s IoT products obviously have the logic of pursuing the ultimate user experience, and the actual use experience is commendable.

Ali: The whole stack does not leave a dead end

In the previous article, the author introduced Ali’s IoT chip. Its operating system Ali Things OS has been developed for more than two years. It has just released version 3.0, and it is also quite advanced for the Internet of Things and artificial intelligence.

OceanBase, its traditional database, has just won the TPC championship, which can be said to be a comprehensive and unobtrusive IoT technology stack.

Huawei: Best Equipment Provider

Huawei’s IoT series products obviously have a cold wind. The Lite OS iteration is not fast, and the interface of the cloud platform is relatively simple. However, the stability and maturity of Huawei products have always been the industry leader.

And we also introduced before, Huawei dominates the technical standards of the Internet of Things NB-lot, and the depth of the technology pool enables Huawei to remain in an undefeated position in the long-term competition.

Baidu: Data Provider

At present, Baidu is the only major manufacturer to launch the timing database product TSDB. Although there is no operating system yet, but from the current trend of full-stack competition, Baidu will not be too far away to launch its own Internet of Things products.

Telecom operators: lost players

Considering the huge scale of the Internet of Things, especially the mobile Internet of Things traffic must run on the telecommunications network, so major operators have set up their own IoT subsidiaries, such as China Mobile.

However, the current business of Telecommunication Corporation is almost limited to the provision of NB-IoT IoT services, and the specific product fees are not transparent.

At the beginning of the mobile internet, China Mobile also launched an OS based on Android customization, but now operators seem to have lost their fighting spirit, just one’s own one-acre. It can be said that the full-stack competition has become a trend, and the simple defense cannot keep up with the pace of the times.

In the future, who is it?

At present, the IoT industry is still in the process of introducing the concept of China and the stage of industrial chain formation. The technical standards and systems of all parties are still rapidly iterating.

The process of its inherent logical evolution has produced a significant self-subversion effect, and the overall industry is on the eve of the brewing outbreak, but only this period has the most opportunities.

The emergence of the Internet era has spawned a series of big explosions such as e-commerce, social, financial technology, etc.Who will fall, the answer will be announced soon.
