Research On Operations Management System Of Tram

With speeding up of the world urban construction pace, the explosive growth of car usage amount and more and more serious urban traffic congestion and air pollution, traffic system needs an innovative method to relieve the problem, which having large carrying capacity, high speed and being environmentally friendly. Modern tram with high speed, large carrying capacity and being environmentally friendly, become one of the effective way to solve the urban traffic problem. At present, the research of modern tram system abroad has achieved fruitfully. In contrast, modern trams in China is still in the initial stage of development, Therefore, there are less research on the system of tram, especially the operation management system. As differences in the operating conditions and the status of the operating line, its management control mode are also different. Therefore, the study of its operation management system has great significance.In this paper, on the basis of modern trolley system research domestic and abroad, according to the specific operating environment and line, the modern tram operation management system is analyzed in theory and technology. On the basis of theoretical analysis and combined with its technical characteristics, key technology of modern tram operation management system is analyzed in detail, requirement of the operation management system function is analyzed comprehensively, raising the design of functions, interfaces, communication and system structure. By the method of modeling and software simulation, the system function module division is completed, software simulation environment is set up. The main works are as follows:First of all, the modern tram operation management system is analyzed in theory and technology exhaustively. According to functional requirements and organizational structure, operation system is planned and designed in line arrangement, station wiring and operation organization. The train position system, communication system and the interface system is analyzed and designed. Based on the work design scheme of general hardware structure has be presented.Second, focusing research on the control functions of operation management system on train route of main line turnout segments in the central control mode. The design scheme of communication of operation management center with turnout controller of main line is put forward in principle of communication interface, hardware connection, communication mode select and communication protocol, etc.Third, the system software simulation environment is constructed. By using the unified modeling language(UML), use case diagram, class diagram and key part of the state diagram of operation management simulation system is built, and achieve the function of every module through software simulation.Finally, through the software simulation method, has realized the simulation of modern trams each function module. Based on the simulation platform, for modern tram operation management system and other subsystems in the software testing, Test results show that the simulation results to some extent, meet the requirement of modern tram operation management system function, and the desired effect.
