针对以往设计的压风机群组耗电量大、噪声污染严重、故障保护不全等不足,提出了压风机组节能的几种措施,分析和讨论了压风机组控制策略与运行模式,采用3层网络架构对压风机群组的设备参数及故障进行监视与保护。利用故障树分析法,分析了压风机群组工作时所有可能出现的故障,用产生式规则描述了故障机理,在知识库的构建上采用了结点规则法来构建链表,建立了链表形数据结构,在推理机方面采用了正反向混合推理的推理策略及搜索空间更小的宽度优先的搜索策略,把系统同时存在的各种具体故障都找出来,并且区分其程度,达到故障诊断的目的。
Aiming at the problems of large power consumption, serious noise pollution and fault protection in the past, the paper put forward several measures to save energy, and analyzed and discussed the control strategy and operation mode of the air-blower unit. The three-layer The network architecture monitors and protects the equipment parameters and faults of the blower fan group. Fault tree analysis method is used to analyze all the possible faults in the operation of the fan-blower group. The production mechanism is used to describe the fault mechanism. In the construction of the knowledge base, the node rule method is adopted to construct the linked list. The linked list data structure , The inference engine adopts the inference strategy of forward and reverse hybrid inference and the search strategy of width-less search in the search space to find out the various specific faults that exist in the system at the same time, and distinguish the extent to achieve the purpose of fault diagnosis .
