The Study Of Micro-computer Automatic Block Between Railway Stations System

The paper is oriented to the science and technique developing item of the ministry of railway which aims at studying on the uniting micro-computer-automatic block between railway stations instrument, The paper study on making up of the cro-computer-automatic block between railway stations system by new way of integrating the micro-computer block between railway stations and the existing axle counting technique. the use of the system changes the existing artificial manner of transacting block between railway stations, while the route of train for leaving stations is transacted, block between railway stations is automatic transacted, in addition, when the whole train arrives in the opposite station, the block instrument in the stations automatic reset according to the axle counting information, the time for transacting block and affirming the train arrival becomes less, the carrying capacity of section is improved evidently, the imperfection of all-relay semiautomatic block which includes no vacancy check for the section and no verification to block instrument full is eliminated, it is important significance of improving carrying safety and the level of carrying automatization.The paper's main content consists of introduction, system echnique level and basic function, system total framework and software total esign,block module design, axle counting module design, communication module design,human-computer interface module design,safety measure and reliability measure. In the introduction, the background , the civil and oversea actuality and the significance of studying on the system is explained;the system technique level and the basic function are described;At the basic of the system technique level and the basic function, the system total framework is designed,both the function of the main and the work principle of the system are explained;At the basic of the principle of software design and the detail demand of the system, the software total design is produced, the real-time performance and multi-task of Dispatching&Supervising System is analysed;the detail design of the main function modules which composed of block module, axle counting module and communication module is explained;At last, both the safety measure and the reliability measure of the system are expatiated.
