接触网作业地线的信息收集装置的研究

Research on the grounding line information-gathering device of catenary operation

目前国内的接触网作业地线挂接和拆除的信息是通过人工直接参与来完成传达和收集的,对于分散性大、距离长的接触网检修作业人工管理信息的方法已经不能满足现代高速铁路对经济、效率以及安全性的要求。设计了一种基于全球移动通信系统GSM、DSP处理器与PC机相结合的接触网作业地线信息收集装置。该装置通过GSM网络以短信通信形式收集各检修作业点的接地线挂接状态信息,并将收集的地线挂接状态信息通过USB接口传输给PC机端的后台信息处理软件进行地理信息标定等处理,最终显示作业地线的挂接状态和挂接区段等信息。该装置可有效地防止误合闸的发生,提高接触网生产的安全性,保障人身和设备安全,为接触网检修作业信息化管理提供硬件平台。

At present,the state information of grounding line connecting and removal is collected and sent by human in domestic catenary operation.This method in dealing with large expansion and long distance ground line overhaul can’t satisfy the requirements of economy,efficiency and satety of modern high-speed railway any longer.In this paper,a grounding line information-gathering device is designed based on GSM,using DSP processor and combining with PC technology.This device collects the information of grounding line and operation signal in the form of SMS,and sends the information from each operation site.Communicating with PC-side software by USB interface,it can display the information of grounding line and the operation sections to achieve the GIS calibration.This device can prevent the false switch on to improve the security of catenary operation,can protect the people and equipment,and can supply the hardware platform for catenary operation of information management.
