Analysis of setups of the control of rail microprocessor systems

Abstract

In the article will have been introduced possibilities following from the application of the microprocessor technology in rail systems of the control of traffic will remain for example of modern signalling on railway crossings. Introduction to microcomputer and microprocessor systems of rail devices will permit to eliminate and to replace disused relay devices with them and raising safety on railway and increasing reliability of used devices. 1. INTRODUCTION Since the beginning of existence of railway lines, devices allowing for safe control of traffic have been applied. Development of devices progresses continuously. Requirement pose them steady increasing as well as needs and expectation of their users. However the major purposes of applying these devices – the safety and efficiency of traffic, remain unchanged. New microprocessor systems meet these requirements. An application of modern information technology and more effective microprocessor systems has a large influence on development of railway transport. They are deciding generally that computer technologies are determining the standard and trends of progress of the technique of the traffic control systems. 2. TECHNOLOGICAL EVOLUTION OF AUTOMATIC OF THE LEVEL CROSSING OF POLISH RAILWAY Systems of automatic of the level crossing being used in Polish railway lines are realized in different technologies. Systems of automatic of the level crossing can be divided with respect to technique of implementation of controlling function into three groups: relays, hybrid (electronic and relays) and microprocessors. About 27% of devices are devices being built on the basis of relays, 59% of devices are devices being built on the basis of hybrid technique and 14% of them are built on the basis of microprocessor. 27% 59% 14% Relay's system Hybrid systems Microprocessor systems Fig.1.
