| Abstract: | Aiming at the characteristic of the chemical polymeric process, combining the merits of BP network and expert system and using the ability of self-studying of BP network and explaining capability of expert system, a fault diagnosis sytem hybrid expert system and BP neural network is constructed. It is used to solve the fault situation in operation process. The simulation results shows that this system can enhance the security and credibility as well as advance diagnostic speed through applying parallel processing of BP network to complete the reasoning process. |
