摘　　要：针对城市污水处理厂运行管理中的实际问题,开发了运行监控与故障诊断专家系统。该系统通过间接读取现场PLC数据以及与操作人员的人机交互,实现了污水处理厂运行状态监控、在线故障诊断和离线故障诊断的功能。运行状态监控采用瞬时监控与累计状态监控相结合的方式,提高了系统的抗干扰能力;故障诊断采用基于故障树和启发式搜索的推理方式,可以简明直观地表达知识,提高推理效率。实际应用结果表明,该专家系统能够有效分析、诊断并解决污水处理系统故障,确保污水处理厂的达标稳定运行。An expert system for operation monitoring and fault diagnosis was developed to solve actual problems in operation and management of municipal wastewater treatment plants. The functions of operation state monitoring, on-line and off-line fault diagnosis can be achieved by indirectly obtaining field PLC data and collecting data from operators. The combination of instantaneous monitoring and accu- mulative state monitoring is adopted in the operation state monitoring module, which enhances anti-interference capacity of the system. The inference mode based on fault tree and heuristic search is applied for fault diagnosis to concisely demonstrate knowledge and enhance inference efficiency. The actual application results show that the expert system can effectively analyze and solve wastewater treatment system faults to ensure stable operation of wastewater treatment plants.
