Study Of Multi-Locomotive Traction Wireless Synchronous Intelligent Control System

Multi-Locomotive Traction Wireless Synchronous Control System was applied widely to our heavy haul railage with it's excellent performance in China. Most of the multi-locomotive traction wireless synchronous control system using in China adopts Locotrol system of GE Co. of America, but its application condition has a large difference in our heavy haul railways. Based on the actuality, the thesis takes the electric power Locomotive of SS3B non-immobility double heading as research object, and based on the project of Multi-Locomotive Traction Wireless Synchronous Control System for Chengdu Railway Company, researched the theory and system meeting our application requirement.After deeply learning and researching the structure and work principle of multi-locomotive wireless synchronous control system both at home and abroad, according to particularity and complexity of our heavy haul railway, besides the Locomotive in use currently. On this condition, the system adopts wireless communications mode realizing the control of locomotive with distributed dynamic, to solve the problems of stability and security of the trains. The thesis focuses on the conclusion of longitudinal dynamics of heavy haul train and excellence manipulation experience of the driver, puts forward feasible control strategy for security of freight train. While the thesis analyses multi-locomotive traction expert system's theory, and it takes a new standpoint and method with longitudinal dynamics allowance as a evaluation standard for train's security, designed the system using intelligent control theory and technology. Introduces the general structure and work principle of the system , the hardware and software design principle of control signal acquisition module, status signal acquisition module, wireless communications transmission module, center control module, output control module and status signal output display module. Finally, introduces the reliability measure of the hardware and software. Combined with the development process of the practical system and results of the thesis, and by test operation in the laboratory, the thesis summarizes the achievements and deficiency of the system, points out author's suggestion, and makes analysis and prospect for this theory and technology in the end.
