公路监测中的一种远程测控终端

A remote terminal unit for highway monitoring system

为了克服公路监测中常规远程测控终端的缺陷,根据公路网监测的特点,通过扩展数据通信接口和建立握手通信协议的方法,设计出适用于公路监测的一种新型远程测控终端。该终端具备能够与光纤、无线及本地总线等通信网络的节点控制器进行通信的能力,从而可使测控距离得以延伸,测控范围得以扩展。

Considering that,the general remote terminal unit doesn＇t work well outsides an area of GSM network coverage,a novel remote terminal unit is designed by expanding the data-traffic interface and establishing the hand-shaking communication protocols.This remote terminal unit can be connected with the fiber,the local wireless network,and other industrial buses,thus,the highway monitoring system can be enabled to implement communications in the region without GSM network,that is to say,the monitoring range and distance is enlarged.
