摘　　要：简要介绍了DMX512和CAN总线局域网的通信协议和特点,给出一种基于DMX512/CAN,CAN/DMX512转换网桥实现DMX512,CAN总线混合通信网的实现方法。该方法充分利用了CAN总线传输速率高、抗干扰能力强、传输距离远的特点,且对基于DMX512协议的舞台灯光设备具有很好的兼容性,为大范围全数字舞台灯光控制系统提供了一种远距离通信的可靠信道。The paper introduces the communication protocols and features of DMX512 and CAN bus local area network. and gives the implement method of mix communication network using switch net bridge - based DMX512/CAN and CAN/ DMX512. The method uses the CAN bus character of high speed, anti-jamming, far distance transmission, and best compatibility for the stage devices based on the DMX512 protocol. The switch net bridge can provide a reliable channel to far distance communication.
