The upper computer 400 comprehensively analyzes the abnormal electric energy parameters collected by the loop state monitoring module 100 and the image information collected by the electricity larceny prevention monitoring module 300, when electricity larceny is judged to occur, an electricity larceny alarm prompt can be sent out in the form of a buzzer or a flash lamp, and the like, so that subsequent workers can go to the site to confirm whether electricity larceny occurs again and make corresponding processing measures. In order to avoid the situation that the non-working personnel and the like cancel the electricity stealing alarm prompt to cause that the working personnel cannot find the electricity stealing behavior in time, the upper computer 400 can generate electricity stealing event record data as electricity stealing event historical data while sending the electricity stealing alarm prompt, and the working personnel can know the actual electricity stealing situation according to the electricity stealing event historical data to further improve the monitoring precision.

The staff can be according to the electricity stealing incident record data that host computer 400 generated, confirm on the spot, if it is the power consumption unusual, then mark, follow-up observation is that accidental power consumption is unusual or the power consumption that exists always is unusual, thereby judge that the electricity stealing condition in power consumption field management terminal 200 place area is the frequent emergence or has the contingency, if frequent power consumption is unusual undulant, need carry out the investigation of probing the reason that influences the power consumption condition in this area, accurate location source, take the improvement measure pertinence, thereby solve the power consumption problem that the unusual power consumption condition area of taking place was met frequently.

Based on the same inventive concept, the embodiment of the invention also provides a monitoring method of the power distribution network electricity larceny prevention monitoring system, the monitoring system is electrically connected with a monitoring object through a plurality of metering loops, and the monitoring system comprises: fig. 3 is a flowchart of a monitoring method of a power distribution network electricity larceny prevention monitoring system according to an embodiment of the present invention, and as shown in fig. 3, the monitoring method includes:

and S110, the loop state monitoring module collects and outputs the electric energy parameters of the correspondingly connected metering loops.

And S120, the power utilization field management terminal receives the electric energy parameters output by the at least one correspondingly connected loop state monitoring module, generates an electric energy parameter abnormal signal when detecting that the electric energy parameters are abnormal, and uploads the electric energy parameter abnormal signal and the abnormal electric energy parameters to the upper computer.

S130, the electricity larceny prevention monitoring module is switched into an image acquisition mode under the trigger of a preset trigger condition, acquires image information of an area where the electricity utilization field management terminal is located according to a preset rule, generates an image abnormal signal, and uploads the image information and the image abnormal signal to an upper computer.

And S140, the upper computer processes and analyzes the abnormal electric energy parameters and the image information to obtain an electricity stealing monitoring result.

The anti-electricity-theft monitoring system comprises a loop state monitoring module, an electricity utilization field management terminal, an anti-electricity-theft monitoring module and an upper computer, wherein the loop state monitoring module acquires electric energy parameters of a metering loop which is correspondingly connected and outputs the electric energy parameters to the electricity utilization field management terminal; the anti-electricity-theft monitoring module is switched into an image acquisition mode under the triggering of a preset triggering condition, acquires image information of an area where the electricity utilization field management terminal is located according to a preset rule, generates an image abnormal signal and uploads the image abnormal signal to the upper computer; the upper computer obtains electricity stealing monitoring results according to abnormal electric energy parameters and image information, the loop state monitoring module can monitor the electric energy parameters of the metering loop in real time, data support is provided for intelligent diagnosis and comprehensive analysis of the monitoring system, electricity stealing prevention monitoring is carried out by the electricity stealing prevention monitoring module in an image acquisition mode, evidence can be obtained for electricity stealing, mutual matching of the electric energy parameter acquisition of the loop state monitoring module and the image acquisition of the electricity stealing prevention monitoring module can be realized, electricity stealing monitoring precision of the monitoring system can be improved, and occurrence of vicious electricity stealing situations can be effectively reduced.
