Abstract


The paper describes the research of low-voltage power-line-communication board based on spread spectrum technology.Due to the superiority on technology and economy ,spread spectrum has a glorious future in the domain of power line communication.The paper based on the actuality of power system in our country.The works of research and development obey correlative stipulate.The communication board is grounded on the right choose of PLC technology and chip.In the core circuit,MSP430F149 has being choosed as main controller and SCI 128 as spread spectrum carrier unit.The data can be transmitted and received through two kind physical interface:power line and serial port.The module of 5-order Butterworth band-pass filter,automatic gain controller,power amplifer has being designed for auxiliary circuit.IAR Embedded Workbench IDE is the development enviroment for the commumication software which written with C programe.The transmit and receive of the data is based on interrupt.The work of the PLC board is stability .It has the advantage of convenience to maintain.It’s valuable to use the PLC board.
