[Abstract]:The National 13th Five-Year Plan will promote the application of smart grid into key projects. Smart ammeter is one of the important terminal equipment of smart grid. It has electric reference metering, data processing, data transmission, fault detection, The functions of fault alarm and remote communication are indispensable for electric energy metering and power grid safety detection in production and life. At present, the networking capability and remote control mode of intelligent meter are developing. It is of great significance to extend the technology of industrial Ethernet and Internet of things, which is now booming, to intelligent meter. Based on the basic application process of traditional intelligent ammeter, this paper makes a deep research on Ethernet communication and short message control function of multi-control function meter. The main contents include: 1. Firstly, the hardware integrated control unit STM32 platform of ammeter is determined. Adopting the "double CPU" solution and cooperating with other hardware modules, the functions of electric reference measurement, bus communication and remote control are realized. The electric meter can communicate seamlessly with other industrial equipment and complete the control task, at the same time, The meter can be easily integrated into the smart grid system. The software architecture based on 渭 C / OS-IIIP and FreeModbus protocol stack is analyzed. The software architecture, such as Modbus communication, short message control and electric reference measurement, is studied deeply. This paper discusses in detail the coordinated communication process between protocol stacks and the conversion of metrological data, encapsulate and enqueue process .3. based on the completed meter, it discusses the implementation process of its application in building system. The relationship between the communication process of the master and slave stations and the variables of the short message function is analyzed emphatically. The power monitoring, short message control, short message alarm and PID control are used in the air conditioning control of buildings to complete the experimental verification. 4, based on the completed meter, This paper discusses the process of its application in the industrial pump house system, especially analyzes the networking mode among the equipments of the pump room and the transmission process of the control data flow, from the short message control, the short message alarm, the short message alarm. Equipment networking and fuzzy control for pump unit control completed the experimental verification. The research results of this paper verify the new idea that intelligent meter can be combined with various control functions, and integrate Ethernet communication and short message control functions on traditional intelligent meter, realize the integration of multi-meter and solve the difficult problem of equipment confusion in the traditional scheme. It also maximizes the computing power of the integrated control unit. The idea and realization process of the paper have certain guiding significance for the development of intelligent ammeter. At the same time, the application of ammeter in many occasions can be realized, and its compatibility and convenience are fully reflected. It also shows that the new intelligent terminal based on intelligent meter will have great prospect.
