Abstract:View of the communication problem on far distance monitor, a new spread spectrum carrier data communication system is designed, which is composed of a PIC microcontroller acting as the main controller, power line as the communication medium, and IC-PL2000 as the physi- cal and data link layer. This paper gives the system diagram and program diagram, and analyzes circuit of every part. Practical operating shows that the system has high reliability and is easy to make network, so as to solve the communication problem of the network management.
Keywords:power line carrier  spread spectrum carrier communication  dual frequency  serial conununication
