Reserch On The Wireless Intelligent Watt-hour Meter

This paper studies and discusses the design method of wireless intelligent watt-hour meter, Wireless smart watt-hour meter adopts the Application Specific Integrated Circuits combined with single chip microcomputer hardware design. Application-specific integrated circuit has the characteristics of fast high precision, Used to complete the electric energy data acquisition and processing, MCU is responsible for data processing sequence control application-specific integrated circuit and the instructions and manual control, this Design put a large amount of data processing and other functions of the separation, To improve the precision of the system and running stability. USES the GPRS wireless data transmission,and reserve the communication interface RS485 bus.The instrument has the functions of measuring all kinds of three-phase electrical quantities with high accuracy and testing the errors of Watt-hour meters on spot.It is an ideal tool for supervision of electric power networks and administration of electricity usage.
