The Study On Measurement And Control Device For Catenary Isolating Switches

With the large-scale construction of China’s high-speed electrified railway, the power supply reliability of the electrified railway is also more and more to be concerned.Catenary isolating switch as one of the most important electrified railway equipment, Because of its quantity and wide distribution,Centralized monitoring remote operation to the isolating switch of the catenary can improve the operation speed pour gate and the safety factor of switch operation, improve the utilization of the break time for repairing, effectively reduce labor intensity the officer on duty. So developing a supervisory system catenary switches to realize catenary isolating switch remote operation has a certain practical value to improve the power supply reliability.The catenary switch monitoring system is composed by the the Catenary switch monitoring device and the catenary switch monitoring and control devices, The catenary switch measurement device is designed in this paper.Based on the overall system design,It analyze the functional requirements of the device.The focus of this paper is the software design of the monitoring and control devices. The program is divided into two parts.one part is the software design of the communication module,it is used to listener and receive packets command generated by the monitoring device itself or forward the dispatch center,and Parse, verify the received packet, The other part is the software design of the functional module which is mainly to complete the specific function of the Remote Communication’s acquisition, the acquisition and control of the temperature, remote execution, and the device parameters Remote modification.The last is to verify the functionality of the software.Number of validation results show that the program has basically completed the functional requirements of the device.
