[Abstract]:Watt-hour meter (Watt-hour Meter) is the terminal product of smart grid construction, and it is an important business in the development of ammeter industry. According to the function and performance requirements of the new standard for single-phase intelligent watt-hour meter, we have designed a new single-phase remote intelligent meter with high precision metering chip ATT7053BU, which not only has high precision metering function. It also has many functions, such as data acquisition, remote control, outage detection, two-way communication, real-time monitoring and so on. Through the connection with the centralized reading system, the management operation on the user's demand side is realized. The remote control of the watt-hour meter is realized by using the RS485 communication mode and the special communication circuit. This paper introduces the main function and performance of intelligent ammeter in detail, and explains the hardware design, software design and system experiment. This watt-hour meter is based on the digital circuit technology, the single chip microcomputer is the core, the hardware circuit and the system software are designed by the way of integrated modularization design, thus a single-phase remote intelligent meter is realized. The whole circuit system is connected by a variety of electrical modules, including metering part, power supply part, clock part, memory part, RS485 communication part, infrared communication part, display part and so on. The function of each module is independent and the interface is unified, which provides convenience for different function combination and call. This paper introduces the key modules such as voltage sampling circuit, current sampling circuit, power supply module, communication module, clock and storage module, and so on. The key modules include clock function, storage function, infrared communication function, RS485 communication function, electric anomaly detection function, etc. The functions of power off control, LCD display, keystroke, safety authentication and so on are combined to realize the function output of intelligent ammeter. At the same time, in the process of hardware design, the performance requirements of watt-hour meter are combined to meet the needs of users.
