On-line inspection system for default electricity utilization based on load monitoring

The invention discloses a default electricity utilization online inspection system based on load monitoring, and relates to the technical field of electricity utilization inspection. The system comprises a non-intrusive acquisition module, an embedded acquisition module, a load decomposition module, an intelligent judgment module and a load feature matching module. The load decomposition module is used for extracting total load characteristic data according to the total residential electricity consumption data; the load characteristic matching module is used for matching first load characteristic data according to the working state change data of the electric appliance, and calculating second load characteristic data through the total load characteristic data and the first load characteristic data; and the intelligent judgment module calculates a default suspicion index according to the inspection rule. The data complexity of the second load characteristic data is lower than that of the load characteristic to
