一种线型组网的三线制数据测量方法
A three-wire data measuring method of linear networking
摘要
Abstract
According to the common linear distributed measure points in engineer practice,a three-wire networking method based on SCM is proposed,which defined three states for the measuring point including standby,activities,digital transparent transmission and the switching protocol,thus the host computer can communicate with the activity measuring point directly by the transparent transmission point. Only one line of communication is used between measure points,and the network protocol is flexible,the connection simple,the transmission distance is far,and the analog signal can also be transmitted. The angle sensor is adopted as an example to illustrated the principle of the method and the hardware,software implementation. The factors affecting the transmission distance are analyzed and the corresponding measures are put forward.关键词
