摘要
针对DMX512协议主从控制器采用双绞线进行通信,在一些不便布线的场合布线困难的问题,提出一种DMX512协议的扩展方法。将无线通信和传统双绞线相结合,无线主控器与DMX512总线连接,其中无线主控制器和无线从控制器采用基于CC1101无线通信方式,主控制器将来自DMX512总线的数据转换成无线形式发送给从控制器,从控制器作为单个灯具节点进行调光操作。在布线困难的地方采用无线通信的方式解决了布线困难的问题。
Because the DMX512 protocol master controller and slave controller uses twisted pair for communication,so in some inconvenient cabling occasions,it is difficulty to wire.In the paper,an extension method of DMX512 protocol is proposed,which combines the wireless communication and the traditional twisted-pair communication method.The wireless host controller is connected with DMX512 bus.The wireless host controller and slave controller communicate with each other through the CC1101.The host controller converts the data from the DMX512 bus into the wireless form and transmits it to the slave controller,then the slave controller performs the dimming operation as a single lighting fixture node.The wireless communication is used where the wiring is difficult,thus the problem of wiring difficulty is solved.
