Research On The Supervisory PC Of Computer-Based Interlocking Simulation System Of Chinese Train Control System 3 Level

Based on the demands of Chinese railway development at present and in the future, the Ministry of Railways proposed Chinese Train Control System(CTCS). As passenger-dedicated line can solve the current problems that shortage of transport capacity and low quality effectively,it is placed in a very important position. At present, China is employing and promoting CTCS-3 class train control system in reconstruct of the existing railways and construct of the new high speed passenger line. Computer-based interlocking system can enhance the safety of the railway, and increase transport capacity. The station signal control of CTCS-3 adopts computer-based interlocking system.CTCS-3 system is large and complex, and computer-based interlocking is one of its subsystems in station.China is in its early stages,and the level of applied technology also need to constantly improve and perfect. Computer simulation technology will play an important role in research and development of CTCS-3 system. Simulating of the CTCS-3 computer-based interlocking supervisory PC system,after referencing to domestic and international technical specifications, is helpful to perfect technology and lay the foundation for the practical application. At the same time, it can also be used to improve effect in the experimental teaching of railway signal major.The establishment of the CTCS-3 computer-based interlocking supervisory PC simulation system is based on system structure and function of CTCS-3 computer-based interlocking and overall technical specification of CTCS-3 system.By analyzing and research on system structure,functions and interfaces of CTCS-3 supervisory PC system, this article has finished specific work as follows:putting forwards to the architecture of CTCS-3 supervisory PC simulation system, as well as the significant functions of and interface requirement of the subsystems; analyzing the design plan of each modules in detail; realizing the functions of supervisory PC by using Visual C++, including MMI information displaying, operation command processing, communicating with CTC and subordinate PC,data storaging and replaying etc.At last,the function of supervisory PC simulation system is validated and perfected by debugging together with other subsystems.
