Computer Interlocking System Station Display Module Design
Abstract: Station computer interlocking system controls the signal equipments of the station by computer and communication technologies, aiming to realize the interlocking relation of the signals, switches and sections. A computer-controlled interlocking has an associated plurality of section computers respectively associated with the section and arranged to be fail-safe in terms of signaling technology. It is one of the basic equipments that ensure the safe operation of trains. The computer-controlled interlocking system for a railway installation which comprises a plurality of sections. The higher level management computer can not only achieve human-computer interaction function between the system operator and interlocking but also display the real time station condition. This thesis focuses on the content of the display module design of station computer interlocking system. The first two chapters introduce the basic elements of computer interlocking system. The third chapter pays attention to detail of the basic equipments in the station map. The fourth chapter tells about how to design the display module using Microsoft Visual C++ program languge. The last chapter demonstrates various functions of the station.
