Abstract
The diagnosis system of Maglev train is introduced in this paper. The system structure and diagnosis method are analyzed and discussed in detail. The disadvantages of diagnosis system are proposed. In virtue of the theory of ADS (autonomous decentralized system), some basic ideas of ADS are applied in new diagnosis system. The structure, component parts and diagnosis method of new diagnosis system are proposed, designed and discussed in detail. The analysis results show that new diagnosis not only embodies some ADS' ideas but also better meet the demands of Maglev train diagnosis system such as the reliability, real-time and autonomous property.
