Design Of Computerization On Changing The Direction Of The Circuit Of Automatic Section Block System

With the popularization and development of computer technology andmicroelectronics technology, miniaturization, informatization and intellectualizationhas become the development trend of modern railway. Along with the demand forpassenger and freight rail, trains traveling and running safety start a new challenge onthe railway equipment.As an important component of the railway signaling systemequipment, automatic block system reform package composed by the relay circuit hasbeen unable to meet the functional requirements of the site. To this end, the papercombines the advantages of computer-based systems, presents a design ofcomputerization on changing the direction of the circuit of automatic section blocksystem, and uses computer technology to achieve all the features of wire section97type automatic blocking reform party circuit.This paper introduces the technology characteristic,the circuit composition andthe working principle and the existing problems of automatic block change partysystem. According to the characteristics and existing problems of automatic blockchange party system, this paper puts forward the design scheme ofmicrocomputerized automatic block section change two wire system. According tothe specific requirements and basic functions of the scheme, this paper finishes theoverall design of hardware. At the same time, this paper finishes the detailed designof hardware structure, drive acquisition module and direction control circuit, andachieves the collection of interlocking information, direction voltage information andinterval orbit state, and finishes the drive of direction control circuit. On the basis ofthe hardware design, combining with the automatic block relay logic relationship ofchange the party circuit, this paper finishes the overall planning and design ofsoftware of the system. The main function modules of software system includes coremodule, drive acquisition module, human-computer interaction module, messagerecording module, user equipment management, fault information, operationalinformation record and query function. At the end, this paper introduces the concreteapplication of microcomputer-based automatic block system, and this applicationmainly includes the combination of station automatic block system computerizationwith electric centralized interlocking and computer interlocking. Issues, such as huge volume, complicated wiring, installation difficulties, highermaintenance costs, of old reform package circuit has been solved in the paper.Whileadding an information recording, device management and other features that make themaintenances more convenient and make users’ responsibilities moreclear.Information recording function records all operating information and faultinformation of users,which makes it more convenient to facilitate the analysis ofequipment failure.The use of computerization on changing the direction of the circuitof automatic section block system will greatly reduce the workload of staff, improvethe work efficiency.Computerization on changing the direction of the circuit ofautomatic section block system will have a very great practical significance on therailway transportation of China.
