What else is the fast -moving industrial and commercial application innovation based on 5G?

The large -scale 5G network construction has long been completed, and after the initial freshness, many people think that 5G compared with the previous 4G, it seems that there is no particularly obvious advantage except the fast speed. But in fact, 5G -based industrial and commercial application innovation has long been in full swing.

As an important window for the whole society to understand the achievements of high -tech innovation, the "Recommended Catalog of Scientific and Technological Innovation Achievements of the Central Enterprise Enterprise", which is regularly released by the State -owned Assets Supervision and Administration Commission of the State Council each year, represents the absolute cutting -edge of the innovation of central enterprises. Nano -gas gel, new aerospace materials, various domestic processors and chips that often appear in science and technology news are regular customers on this form. In the catalogs in recent years, 5G related products and applications have been on the list; it is high to see 5G innovation.

In the latest release of the "Recommended Catalog of Scientific and Technological Innovation Achievements of the Central Enterprise (2022 Edition)", China Mobile's latest 5G smart power gateway products have been successfully launched on the list; and this also marks that 5G technology has successfully resolved the solution of 5G technology. Another business pain point of the power system.

Solve the big problem of "what time" for the power grid system

At first glance, the new 5G smart power gateway is similar to ordinary home routers. In fact, the role of 5G smart power gateways is to use 5G networks to connect various devices; this is generally comparable to the 5G CPE routing function bought in the business hall. It's just that 5G CPE usually converts 5G signals into WIFI networks, and this 5G smart power gateway is to convert 5G signals into wired networks.

So why does 5G Smart Power Gatement go to the "Recommended Catalog of Scientific and Technological Innovation Achievements (2022)" with a very heavy weight? The key innovation lies in the precise timing function designed for the needs of the grid.

The power grid connects millions of households, thousands of travels and hundreds of industry, is a key infrastructure to maintain normal social and economic operation and development. To provide electricity for 9.6 million square kilometers of land and 1.4 billion people, the scale and complexity of the power grid can be imagined. In order to maintain the normal operation of the power grid, a large number of sensors and detection equipment were installed in various types of power transmission, substation, and power distribution nodes of the grid. The massive information generated by these devices is connected to control centers at all levels through the network.

In the actual grid operation and maintenance process, managers usually need to determine the fault point according to the time order of problems and abnormal phenomena, thereby guiding subsequent maintenance work. But we know that the theoretical spread is 300,000 kilometers per second at the same time as light. Although this speed will be affected by the media, it is still extremely fast. Therefore, to determine the order of the problem, the various types of information transmitted by the grid detection equipment must be stamped with an extremely accurate "timestamp".

How accurate is it? Generally, microsecond levels are required, that is, 9 digits after the decimal point.

Obviously, the accuracy level of about 10 milliseconds in the ordinary network cannot meet the demand; the traditional approach is to achieve through satellite -based specialties. Such a specialized fashion device is not only expensive, but also increases the complexity and fault points of the node system. The 5G smart power gateway launched by the China Internet of Things not only has an accurate timing function, but also combines network communication and timing equipment. It also reduces the cost of system complexity, failure and subsequent maintenance while reducing the cost of equipment; The actual significance is quite significant.

According to the actual performance test of the third -party laboratory, the new 5G smart power gateway can be covered with accurate errors with a 500 -nan second second seconds under the base stations of different solutions of China Mobile 5G networks.

At the same time, 5G Smart Power Gateway also provides VPN tunnel encryption technology, which can greatly improve the transmission security level of the grid operation data and improve the reliability and security of data transmission.

5G communication+granting, not just an economic account

Although the network communication+timing function provided by 5G smart power gateway is easy to understand, it provides a solid foundation for the continuous development and transformation of the power grid.

First of all, from the macro development level of the grid, with the comprehensive use of new energy vehicles, urban -level energy storage units, and various types of green power generation methods, the structure of the power distribution network is becoming more and more complicated; The high -quality operation of the distribution network is undoubtedly higher. The current feasible solution is to distribute the distribution network, and achieve more accurate control by dividing the distribution network into a "small grid" with higher particle size. The 5G smart power gateway with lower cost and more accurate time can make the distribution network transform easier. When distributed and accurate teaching, the power grid not only has the ability to instantly respond instantly when the failure occurs, but also limits the influence to as small as possible, thereby achieving the overall high and reliability of the distribution network; Improve the overall quality of the distribution network.

Secondly, the characteristics of large bandwidth and low latency of the 5G network itself can also provide a wider data channel and higher data timeliness for the massive equipment of the power grid, and provide the basis for the remote test, remote letter and remote control and automation control of the power grid. By help to achieve automation and intelligence of the operation and management of the power grid.

Third, in terms of running parameter measurement for micro -facing networks, the higher bandwidth and more accurate time for 5G smart power gateway will be conducive to PMU (synchronous phase measurement unit, which can measure the waveform change of AC power at all times, thereby thereby Provide data foundations for power grid management and regulation) to obtain more accurate measurement values, and provide more powerful data foundations for the optimization, regulation and rapid response of the distribution network. With the continuous advancement of the digital transformation of the grid, the various functions of 5G smart power gateway will also be widely used, and the management and operation level of the grid will continue to strengthen.

5G has already been moist

As the industry's first product that solves the precise timing problem of grid equipment with 5G networks, the 5G smart power gateway of the China Migration IoT has completed functional and performance testing and program verification, and is undergoing batch deployment and has received unanimous praise from users. For such a "small box" that can solve big problems, it is true that the "Recommended Catalog of Scientific and Technological Innovation Achievements (2022)" of the Central Enterprise Enterprise.

From 3G to 4G to 5G, the continuous evolution of the wireless communication network is not only brought about higher bandwidth, but also the comprehensive improvement of many characteristics such as network loading capacity, reliability, certainty, and low latency. And this is also the core cause of 5G communication networks that can enter commercial, industrial and even national key infrastructure fields.

Compared to 3G's "digital first taste" and 4G "experience upgrade", 5G brings the full -dimensional evolution of thousands of industries and everything. With the continuous advancement of corporate innovation represented by China Mobile, more and more industries and application scenarios will be further in digital transformation. The ultimate benefit is the whole society and each of us.

From this point of view, 5G's innovation is more like moisturizing; it seems silent, but it can give birth to all wonderful.
