动车组牵引电机温度监测系统的设计与实现

Design and Realization of the Temperature Monitoring System for Traction Motors on Multiple Units

为了实时监测动车组牵引电机的表面温度,及早发现电机故障,提出了采用无线扩频技术,形成各节点可以自动组网的自由拓扑结构,实时监测牵引电机温度,再通过GPRS无线网络,将每列车的数据实时传送到动车调度中心。

In order to monitor the surface temperature of traction motors on multiple units in real time and to find the troubles in motors as early as possible,it is put forward in the paper that the wireless spread spectrum technique shall be applied,to form the free topoligical structure with the nodes being able to form network automatically,to monitor the temperature of traction motor in real time,and through the GPRS radio network,to transmit the data of each train to the dispatching center of multiple units in real time.
