Power line carrier communication technology is used widely. Low-voltage carrier communication equipment which will help the electricity sector to make sure of the user’s electricity consumption in time, monitor whether the user have the actions of stealing electricity ; According to the need for power supply control; through remote meter-reading to save the human and material resources. In the field of automatic household appliances control of the application of and prospects will be very broad.
Low-voltage power line carrier meter reading system is set meter data collection, transmission carrier, data storage, data communications, data processing and power control functions in the integrated automation system.
This paper is aimed at low-voltage power line carrier meter reading system in the carrier communication module is designed. The module is composed of power part,the RS232 interface part, the carrier interface part ,the single-chip microcomputer(SCM) interface part, and other interface circuit components.
Through the company of Fuxing-Xiaocheng’s single-chip microcomputer chip (PL3201) in the completion of data communications circuits (power line) launched the spread spectrum, spread spectrum receiver; The module receives the PC serial port’s the 232 data, completes serial data validation and analytical processing, and comes true the power line carrier of data transmittion, can also receive data carrier, after the return to the PC, the operating results from the computer, the data channel Test shows.
