The so-called "ubiquitous power Internet of things" refers to the intelligent service system with the characteristics of comprehensive state perception, information processing, convenient and flexible application, which makes full use of modern information technology and advanced communication technology, such as mobile Internet and artificial intelligence, to realize the interconnection of everything and human-computer interaction in all aspects of the power system.
The narrow band Internet of things (NB IOT) based on cell is an important branch of the Internet of things. It is a new generation of narrow band Internet of things transmission technology, which is formulated by China and implemented in the world. Compared with the traditional 2G network, Nb IOT has the outstanding characteristics of wide coverage, low power consumption, low cost, strong signal, etc., especially suitable for continuous automatic transmission in the energy management field such as "water, electricity, gas" Data, low-power, long-period monitoring scenarios.
With the deepening of the construction of "ubiquitous power Internet of things", smart meters and power information acquisition system products based on Nb IOT technology will play an important role in the construction of "ubiquitous power Internet of things", especially NB IOT smart meters.
As an important sensing device at the end of the sensing layer of the power Internet of things, Nb IOT intelligent energy meter is endowed with more requirements in terms of its technical functions. It is necessary to take into account both the traditional metering functions and the business requirements in the power Internet of things environment.
In the exhibition area of State Grid Corporation of China, the Third World Smart conference held in Tianjin in July this year, the advanced concept, application scenario and intelligent experience of power Internet of things construction attracted many visitors. Among them, the new generation of smart watt hour meter is favored by visitors.
The new generation of intelligent energy meter can quickly perceive the power outage and restoration status of customers, locate the fault location, realize active repair, and drive the new mode of distribution operation and maintenance with data. In addition, through the embedded modular chip, it also has the intelligent load identification function. After the customer installs the mobile app, the real-time energy consumption, start and stop time and other information of various electrical appliances in the home can be seen at a glance, and the energy consumption data of electrical appliances can be found in time.
According to the data of the National Bureau of statistics, the per capita monthly electricity consumption in China is about one sixth of that in developed countries. With the rapid development of China's economy and the improvement of living standards, China's per capita monthly electricity consumption is bound to grow rapidly. The Nb IOT smart meter that helps residents realize smart electricity consumption is bound to play a significant role, and its application will be more and more.
In recent years, the deep integration between smart meters and smart cloud platforms has brought closer interaction among power grid, enterprises and users. At present, 540 million smart meters and other terminals are connected to state grid, but this is still insufficient to meet the strategic goal of "three types and two networks" proposed by State Grid.
At the same time, the structure and function of the new generation of intelligent energy meter will be more flexible and perfect. It will adopt modular design. The metering core and management core are relatively independent. It is equipped with uplink and downlink communication modules, and various business application modules are flexibly configured, so as to reserve sufficient space for the business needs to be expanded in the future, with strong compatibility and scalability.
With the promotion and implementation of the construction of "ubiquitous power Internet of things", as well as the expansion of the deployment scope of Nb IOT base stations of the three major operators, Nb IOT smart meters will usher in a huge application space, and become an industry area that benefits from the construction of ubiquitous power Internet of things actively promoted by State Grid. Enterprises with advanced technology and application experience in NB IOT smart meters will make great achievements!
