In 889, a German from the Gangz company in Hungary produced the world's first inductive electric energy meter, and China's AC inductive electric energy meter was produced in the 1950s from the imitation of foreign electric energy meters. After years of efforts, China The manufacture of electric energy meters has reached a considerable level and scale. In 2009, after the British government first applied the research and production of the first batch of electric meters with network communication functions to household electricity, China National Grid immediately proposed the concept of “smart meter” in China. So, what will the smart meter look like in the future? Let’s look at it together.
Viewpoint 1: Functional modularity and interface integration
Functional setting modularity
The function setting of the smart energy meter must support the concept of updateable or writable, so it is necessary to continuously improve the function setting of the smart energy meter based on the principle of modularization of function settings. In actual operation, according to the operation of the smart grid, remotely set or modify the functions and schemes of the smart meter, and require all functions to be independent threads, without mutual interference and influence, to ensure stability and security, that is, no need to replace the entire table, It also eliminated the obstacles to the implementation of new technologies.
Interface integration
The detection of electric energy meters has always been a complicated manpower, and smart energy meters must change the existing energy meter detection mode to achieve intelligent and automated detection methods. There are too many types of weak electrical interfaces of smart energy meters, which need to be frequently switched during the detection process, which leads to problems such as high labor intensity, high resource occupation, high management cost, low efficiency, etc., and a large number of interface settings cannot guarantee the reliability of electrical safety. , which in turn affects the accuracy of energy metering.
 The development of smart grids or advanced measurement systems has placed more and more demands on smart energy meters, and has also had a profound impact on the "smart" effect of smart meters. The data processing, module design, detection methods and interface types of the existing smart meters are not enough to meet future application requirements. In the future, smart power meters should have information features such as information, automation, and intelligence in terms of appearance, use, and function, so as to provide a faster way for the popularization of smart energy meters.
Viewpoint 2: A special industry will rise
The development of electric energy meters will probably go through the following stages:
Single-phase electric energy meter. Solve the problem of billing accuracy.
Rail type electric energy meter. Optimized shape design and improved installation efficiency. The volume is small, the production is simple, the appearance is beautiful, and the installation is convenient.
 Integrated single-phase AC energy metering solution. The advantage is to optimize BOM cost, optimize assembly efficiency, and optimize design.
 Dedicated metering module. Resolve production efficiency while balancing the needs of miniaturized design. The integrated solution integrates the sampling unit and processing unit on a small module and is very small.
 Generation of electrical parameter sensors. At this point, meter and energy metering will gradually be infiltrated, eroded and occupied by the field of integrated circuit manufacturing. There are calibration-free, self-calibrating electrical parameter sensors, and foreign chip manufacturers are pushing calibration and self-calibrating sensors.
 The electric parameter sensor is small in size, the first joint of the little finger is so large, and the sampling part, AD conversion and mcu are all made in a small box, which further simplifies the technical development difficulty of the measuring part, and the development cycle is shorter and the quality is higher. . Manufacturers do not need to buy a school desk.
In the future, it will not take long for the meter to undergo a revolution. The metering part can be used as a single component. Whether it is industrial production or quality control, there will be a special industry to make electrical parameter sensors with excellent performance and reliable quality.
Viewpoint 3: Informatization, intelligence and modularity
Let me first talk about the new demand points for smart meters in the future:
Industrialization, information and intelligent manufacturing
Big data, communication timeliness requirements
Two-way interaction, self-healing self-diagnosis
MEMS new sensor technology
IR46 requirements, IEC62052-31
The next generation of smart meters must be intelligent manufacturing. Future basic components, basic raw materials, basic processes, and industrial technology base will be improved. Precision machining and measurement testing are the technical basis for process control. The accuracy of measurement and test directly affects the quality of products and affects the efficiency of enterprises.
RFID, MEMS new sensor technology, micro-sensing technology, to ensure accurate and reliable sensor value. It is necessary to strengthen research on new measurement and testing technologies such as remote transmission, remote transmission calibration, and flat calibration. Realize the intelligent manufacturing of information technology in the Internet of Things.
At present, the domestic industrialization capability is far from the foreign countries. The only way to deal with the challenges of the domestic and foreign markets is modularity. A flexible product or system consisting of modules that can adapt to diverse needs and organize specialized production, can be quickly combined into new products, and integrated through a common interface. Modularity in the future is not just about hardware, but also about the modularity of software and processes.
