The Research And Application Of The Power Supply Safety Management System For Rail Transit

With the development of computer and network communication technology,and the requirement of the reliability of the safety in rail transportation industry especially in city rail industry and the safe operation of the equipment management,the subway company also issued relevant management rules and regulations.We all know that the safety of the power supply system is the base of the rail transportation system.The power supply in subway always follow the principle: safety first,prevention first.After fully understand the particularity,complexity and importance of safety production in the subway,in the subway construction and operation management process,we always put heaviest emphasis on the safety of subway operation as the work of the enterprise.But there is not any power supply management system that can support the rail transportation industry.Nowadays,many units as the members of the national grid power use the deeply development by many enterprises to ensure the safety of the power supply,and there are many mature modules,such as the five defense systems,video surveillance systems,etc..However,the system is mainly aimed at the power grid,power plants and other users.There is no in-depth study and research on the rail transportation industry.The existing system can not meet the specific requirements of the rail transportation industry,and this is why we design a power supply safety management system.The thesis analyses the requirement of the user in the rail transportation industry,and combining with the development of computer technology to study and develop the rail transportation power supply safety management system,and finishes the system which can be used in rail transportation industry.According to the difference of power supply in rail transportation industry and power supply in grid power,it designed the logical relationship followed the relevant safety of power supply system,and designed the software functions followed the power supply network topology of rail transportation industry.Through the realization of online anti misoperation function and online locking function,a user can conduct operations in strict accordance with the operating rules and procedures,and it also makes true that the software logic does not meet anti false logic,and can promptly disconnect anti misoperation locking the corresponding node,and ensure no misoperation.Through the rational software system design,strengthen the reliability of power supply system,and improve the safety operation level of the equipment in the rail transportation industry,and ensure the stable operation of urban rail transit.This system is mainly composed of anti misoperation system,line management,function,operation ticket,function ticket and inspection module.According to realize the functions and good human-computer interaction interface,the software can provide reliable support and guarantee for the management of the safety of the power supply in the rail transportation industry.
