基于FPGA的数字式变电站测控装置通讯总线设计

urrently, the transformer substations are becoming digitalized as well as interconnected. The technology of FPGA (Field Programmable Gate Array) employed greatly enhance the performances of testing equipment and the stability of the substation. The paper designs the BUS LVDS based on FPGA to accomplish the communication between master control module and intelligence module in measurement and control devices for digital transformer substation. It introduces the design of hardware and software. In the achievement of software for bus, it mainly has achieved the bus terminal of the master module to receive and send data, and constitutes the communication protocol.
