| This paper studies the multi-function intelligent electric power monitor is the integration of computer technology, network technology, communication technology, semiconductor technology and software technology as a whole, according to the power systems, industrial and mining enterprises, public facilities, Intelligent Building, intelligent community monitoring require-ments and design with modern advanced level of intelligent instrument.Multi-function intelligent electric power monitor with field programm-able, automatic measurement, LCD display, digital communications, electric parameter display, user defined data configuration, software digital calibration, transmission and other functions.It integrates digital, intelligent, networked in one, which makes the measuring process and data processing automation, such as voltage, current, power, power factor and frequency of such important electric parameters for real-time detection, but also on power system harmonics and the accurate measurement of electrical parameters, monitoring, thereby ensuring power system security, reliable, economic operation. It can fully replace the electricity transmitter, power meter, digital display instrument, data collector and other instruments, With compact structure, advanced measuring circuit, strong function characte-ristics.The research project based on ASIC electric power metering ASIC, enhanced51MCU main control unit, using CPLD to complete a variety of communication and I/O interface circuit design; software based on embedded real-time operating system RTX design, high reliability, good portability. The CAN-bus485-bus communication function, can be completed with different PLC of industry or industrial control system networking. |
