一种新型的分布式远程测试现场总线

A Novel Field Bus for Distributed Remote Measurement

提出了一种新型的基于同步数据传输的分布式远程测试现场总线,协议采用全双工的通信方式,主控制器和各现场测试设备之间利用差分信号进行控制命令和测试数据的同步串行传输。详细描述了该总线的物理连接方式、工作时序和控制流程。给出了一种应用实例。

A novel field bus for distributed remote measurement based on synchronous data communication is presented. The protocol adopts full-duplex communication mode. So the master control unit (MCU) can not only send the controlling command to the field testing equipments but also receive the testing information feed back. The signals among the master control unit and the field testing equipments are serial and synchronous. The physical connection mode, the operating timing and the control flow are described. At last, one application example is presented.
