Automatic loading control circuit fault diagnosis system

Automatic loading control circuit is as an important component of automatic loading system, its work's reliability directly affects the system's operational effectiveness and its safety, its fault diagnosis is important to improve the reliability of the automatic loading system. Based on describing the fault diagnosis system's structure and function of the automatic loading control circuit, CPU's reset circuit of automatically loading control circuit is as example, the fault tree method is introduced, the fault dictionary is established, and the corresponding software diagnostic process is given. Finally, according to the end of event probability, CPU's failure probability and the importance of bottom events are identified. Experiments show that the method is correct and effective.
