CTC-based Simulation System Of Interlocking Design And Implementation

At present with the gradual increase in rail traffic, railway stations operating systems are increasingly high requirements. Through the computer network, communications and control technology, Decentralized and self-regulated centralized traffic control system achieve the train and shunting of the station intelligent.When decentralized and self-regulated centralized traffic control system decentralized autonomous controls on station.the station interlocking system ensure that interlocking relationship to achieve the function of distributed scheduling of the various stations. Based on the TDCS, the CTC should have the train operation plan manual, automatic adjustment, the actual operation of drawing in paint, traffic logs automatically generated, storage, printing, scheduling delivery order, train No.check function. For testing CTC system in the actual operation of the effect of the implementation process, designe a interlocking simulation system based on CTC to detect the test results of CTC system.By analyzing the results to optimize the CTC in order to achieve a more efficient and safe and reliable system platform.Firstly, paper introdues the history and current status of interlocking system and CTC,and on this basis, the functional requirements of interlocking simulation simulation are proposed,and then introduced the structure of each system under the platform and their function and data flow. Paper mainly studies the interlocking simulation system of a single station, IPC also achieves a multi-station display.The paper mainly includes:By interlocking simulation system needs analysis implement various types of profile data,connect with autonomous controlling machine through ethernet,complete the interface debugging Interlocking simulation system based on needs analysis, to achieve the profile station types of data, Machine via an Ethernet connection and autonomous controlling machine to complete the interface debugging, real-time display update the present information of the station,complete core functions of the interlocking simulation system:Automatically arrange into the roadand take car in the road and interval, then send station display information to autonomous controlling machine.Paper starts from the research of functional requirements of decentralized and self-regulated centralized traffic control system and technical conditions of a new generation of CTC. Overall structure of interlocking simulation system,data flow,each module has elaborated detailed,and highlights the core functions of the interlocking simulation system.Finally,communication between simulation and autonomuos controlling machine is demonstrated and descripted.
