The Design Of Aptitude Display Module In The Customization Of Computer-based Interlocking System

Computer-based interlocking system is the control system applied in the field of railway signal control, which is used to protect traffic safety and enhance transport efficiency.With the rapid development of high-speed railway, railway transportation department has the higher requirements of technologic development to meet the needs of the development of rail transport.In this paper, we expatiate a concept of customization of operating and display machine in the computer-bassed interlock system.We divide the operating and display machine into different functional modules, each module comunicated with others as a node in the network, and two same equipments are prepared for each module, these measures enhanced the reliability of the whole system, and prevent the system into paralysis with the reason of some module's fault.Thanks to its high reliability, customization and good replantment, embedded Linux system has universial application both in business and industry market. This paper's research based on the embedded Linux arm9 processor developmnet board , and discuss the development methods of customization of operating and display machine.What I have done in this paper is that below: I analyse the hierarchical structure and function of the existing computer-based interlocking system, and expatiate the method of customization of computer-based interlocking system. I also put forward the design method of aptitude display module, and carry out the functions of data center, date communication, station yard display and so on. At last, the SIL in the computer-based interlocking system is analysed.
