On-line diagnosis for Sync brake system of combined train based on multi-agent technique

In view of that Sync brake system of combined-train has a complex configuration and distributed control characteristic, an on-line diagnosis system based on multi-agent technique is designed. The diagnosis system is a two-level multi-agent system, in which diagnosis tasks are divided into simple tasks and accomplished by agents with collaboration. Based on the design of the diagnosis system, the key problems such as the mechanism of task decomposition as well as agent collaboration are resolved. The application results show the validity of this diagnosis method.

Research and application on pneumatic pipe leakage diagnosis technology for freight train

To solve pneumatic pipe leakage of freight train, a base flow detection algorithm is proposed. Firstly principle of pneumatic brake system is analysed, workflow and fault characteristics of pneumatic pipe leakage are researched. Then detection process of pneumatic pipe leakage is designed with maintenance requirement. At last a base flow leakage diagnosis algorithm is discussed and verified. Experiment datas indicate this diagnosis technology ensure the dynamic operating conditions and security of the algorithm reliability with stability.
