基于DSP和FPGA的CANopen-HDLC网关设计与实现

摘要

This paper designs a CANopen-HDLC Gateway based on DSP and FPGA. Using a DSP to complete the CANopen slave,a FPGA to complete HDLC optical fiber communication. This paper completed the design of the system hardware and software,and gives the block diagram of hardware and designand software flow chart,a long time running tests in the wind farm. This gateway was designed to complete the communication between the main control system and the core control unit of wind power converter.The practical results shows that the gateway has the advantages of high reliability, strong anti-jamming capability, fast response. The gateway meets the communication needs in the harsh environment.%设计了一种基于DSP和FPGA的CANopen-HDLC网关,用DSP实现CANopen从站功能,FPGA实现HDLC光纤通信.完成了系统的软硬件设计,给出了硬件电路图和软件流程图.应用于风电变流器与主控系统之间的通信,在风电场进行了长时间现场运行测试.实际运行结果表明,该网关具有可靠性高、抗干扰能力强、响应速度快等优点,可以满足恶劣环境下的通信需要.
