摘要：An Expert System has been developed for monitoring the abnormal process and avoiding the dangers of purifying units in ammonia plant in this work. The regular knowledge expression method of"rule frame + rule body" is used to building the knowledge base. It uses hybrid strategy for inference Engine. Tire system is stable and reliable when put into operation, and it can monitor the abnormal process real-time, keep away the dangers of purifying units in ammonia plant, and realize fault-tolerant control under certain operation state.
