Research Of Stationary Interlock Logic System And Implementation Of Software For Low-speed Maglev Train

The low-speed maglev train which suspended on the track by electromagnetic forces and advanced by linear synchronous is a new-style land vehicle. The stationary control system which core function is interlock logic control is a significant part of the train operation control system. The switch, route and train control are disposed and the train operating safe are protected by the interlocking system.The low-speed maglev train has already developed successfully while the related research of train operation control system is still at the initial stage. Different from the traditional wheel-track train, the low-speed maglev train uses high-precision positioning technology, moving block technology, and real-time large-capacity vehicle-to-ground communication technology, which makes the traditional interlock logic changed. Referenced the successful experiences of conventional train interlocking system, stationary interlocking relationship was proposed in this thesis with the application background of low-speed maglev system. Then interlocking system software was implemented and the simulation environment was developed. In the end, test verification of the interlocking logic system was accomplished based on the environment.Research work in this thesis is focused on the followings:Firstly, elements of the low-speed maglev train system were analyzed. The differences in train control system between the maglev train and the traditional train on positioning technology, train-ground communication technology, and block technology and the impact on the interlocking system were studied. The stationary interlock logic system of the low-speed maglev train control system was proposed.Secondly, the functional requirement was analyzed and the whole structure was designed based on the stationary interlocking system of the low-speed Maglev train. The software was divided into module. Then the static and the dynamic data structure were constructed.Thirdly, the software of the interlocking system which includes the route found process module, the lock release process module and other modules were designed and accomplished.Finally, the simulation environment of the interlocking software was designed. MMI (Man-Machine Interface), TCC (Train Control Center) and equipment simulation software were implemented. The test plan was devised, and the relevant system functionwas verified.
