In view that the problems and loopholes of the centralized management and the real-time monitoring of the ground wire exist in the process of the contact wire maintenance, the GIS platform is introduced to complete the continuous position and dynamic display of the ground operation position and the linked state in the electronic map by using the secondary development of MapX. In the network environment, with the technology of Web and database interconnection and Ajax, the information sharing subsystem of ground wire operation based on the browser/server (B/S) is developed. This paper realizes temporary grounding tools for coding, identification and management, operating status monitoring and location, stopping power security detection, leakage warning tips, real-time information sharing of cross platform and other functions, meeting the requirements of the field operation for the dynamic management and monitoring of the grounding wire.
