| Abstract: | To ensure the stable operation of complex solar hot water system,it is necessary to collect real-time running data,from which to obtain the fault characteristic signal,and to carry out automatic fault diagnosis through expert system.Based on the fault tree analysis method,and taking the typical fault of solar thermal utilization system as an example,the fault tree is constructed and the minimum cut set is solved. Based on this,the diagnostic knowledge base is established;Combining forward reasoning with artificial decision-making mechanism to diagnose and locate faults,a fault diagnosis expert system is established. The fault diagnosis software was developed and tested in the project to verify the accuracy of fault identification. |
