The Research On Urban Rail Transit Station Signal Equipment Comprehensive Monitoring System

With the acceleration of urbanization, urban rail transit has brought great convenience to people’s travel. The integrated monitoring system is support technology for the safe transportation and efficient operations of urban rail transit. Therefore, the study of rail transit comprehensive monitoring system has become a key technology of the research field of rail transportation.This paper is on the base of the discuss and analysis of objective, requirements and functions of rail transit comprehensive monitoring system, which combined with the Shanghai Metro Line13urban rail transit station signal equipment integrated monitoring system project of Casco Signal Ltd. The paper focuses on the following work:1. Participate the overall technical design of the station signal equipment integrated monitoring system. Make sure that clearing the basis processes an requirements of the project, including data acquisition, data storage and data processing.2. Analysis the functional requirements and technical specifications of terminal display subsystem of the station signal equipment integrated monitoring system. Establish the station equipment fault tree to analysis the equipment fault information.3. Design and definite the data structure which is related with the terminal display subsystem of the station signal equipment integrated monitoring system’ Terminal subsystem contains1,800kinds of fault alarm information, equipment status library and graphics library, including four types of station signal equipment, such as interlock, power, axle and signal filament.4. Built workflow of the terminal display subsystem of station signal equipment comprehensive monitoring system, and use the existing graphics tools and other tools to develop and implement the function of terminal display and fault alarm display. Simulation of terminal display subsystem has showed that the developed project of the station signal equipment integrated monitoring system had met the needs of applications on the site. Author designed the terminal display system, fault library and display graphics library. And they have many advantages, such as simple structure, easy operation, intuitive status display, accurate fault location. The simulation of project has fully met the functional requirements of the system visualization.
