Standard power utilization characteristic library establishing method, environmental protection monitoring method, system and monitor

The invention provides a standard power utilization characteristic library establishing method, an environmental protection monitoring method, an environmental protection monitoring system and a monitor. A power utilization characteristic model of pollution production equipment and pollution treatment equipment is established by acquiring power utilization characteristic data of the pollution production equipment and the pollution treatment equipment of a monitored object, and online monitoring is performed through basic power utilization characteristics and advanced power utilization characteristics of a working process, a similarity threshold judgment algorithm is used for accurately identifying the pollution production equipment, the pollution treatment equipment and the working statesthereof. Monitoring failure caused by the fact that false equipment is connected into fake pollution control equipment to work can be effectively avoided. 本发明提供了一种标准用电特征库建立方法、环保监测方法、系统和监测仪，通过获取被监测对象的产污设备和治污设备的用电特征数据，建立产污设备、治污
