Design And Implementation Of Mass Transit Automatic Train Supervision System

Mass transit has been listed in the first scheme to solve the transportation predicament coming form the city citizen rapidly increasing through economic development.Signaling system is critical equipment in E&M systems to ensure the safety running for trains.The automatic train supervision(ATS) system lying on the top level of the signal system,is the command center of the whole metro signal system, which has most directly influence to the operation efficiency,automation degree,management level and work intension of traffic operator.And this task which,is developed to make the automatic train supervision System of mass transit.The thesis discusses the mass transit automatic train supervision system design and realization.Firstly,the thesis introduces the concept,classify, composition and development trend of mass transit signaiing system(so called train automatic control system),then focuses on the function,status in quo and trend of automatic train supervision system(abbreviation ATS),and next, the thesis expatiates the hardware & software structure and module design of ATS,which is mainly accomplished by myself;at last,the thesis discuss to the core functions like route setting,train regulation designed by myself and other core function like train tracking in detail.During the design of ATS,the characteristic of the mass transit such as high density and big traffic flow was considered,and the system design is different from the traditional CTC system.The multi-strategy of train regulation was adopted to enhance the efficiency of regulation and to reduce the work pressure of operator.It was awarded the national patent,Many design technology was adopted to fulfill the requirement of ATS system such as requirement analysis by UML,design method of object-oriented, multi-layer distributed system structure based on COM/DCOM and uniform data access.The appliance of those technologies was described also.
