Abstract：
Analyses the fault causes of the burnt electric motor in air conditioning unit in the plant and management room system of an underground railway station in Shanghai. Establishes a fault tree, and obtains the parameter set of the burnt electric motor in air conditioning unit. By analysing these parameters, it can be determined whether fault exists in the system, the causes of the fault, the location of the fault and how to eliminate faults.
