Scheme and Realization of Operation Control System of Low Middle Speed Magnetic Levitation Vehicle

Magnetic levitation vehicle realizes its levitation and guidance through electromagnetic force,and linear motor provides the driving power. In a low speed maglev train (LSM), each vehicle has the basic functions mentioned above and its electrical equipment is distributed evenly along the train, so as to meet the needs for scattered and centralized control bus method. Based on the test line of low speed maglev vehicles in UNDT (University of National Defense Technology), this paper introduces the basic functions of the operation control system of LSM, chiefly including the functions of operation, protection and monitoring, elaborates the structure of multi-bus principle and the composition design on each node on the basis of the functional demand and the experimental result. On the trial line of the low speed magnetic vehicles,according to the general layout of the operation and control system mentioned above, a hardware system and the related control software have been developed and tested on the vehicle. Up to July 2005, the train had been running for about 8 000 kilometers on a 204-meter long line without any safety problems. The trial result indicates that the design of the operating-control system is feasible, which has laid a solid foundation for the improvement and development of this system in the design of the low speed maglev vehicles in the future.
