Indicating light status real time monitor and identification method for power equipment fault indicator

Abstract

The invention relates to the power distribution net monitoring field and provides a real-time state monitoring recognition method for indicator lights of a power device fault indicator. In the method, digital video signals collected by image collecting equipment of a camera, and the like are processed; video frames are extracted from the video signals; monitoring targets are determined, that is the target region of each indicator light in the video frames, and corresponding numbers are distributed; the pixel color change and the intensity roughness of each indicator light in the target regions of two adjacent frames are used for identifying the flash alarming of the fault indicator; specific conditions of faults are determined according to the identified target numbers of the flash alarming and the combinations thereof; the result is real-timely transmitted to a backstage by a distribution communication network to remind working personnel of the fault happening. The real-time state monitoring recognition method realizes the real-time monitoring recognition alarming for the light state of the fault indicator of the power equipment, ensures the reliability of a system, facilitates the installation and the modification of the system and guarantees the safety of installing and maintaining personnel.

Description

technical field [0001] The invention relates to the fields of digital video monitoring, image recognition technology and electric power distribution network monitoring, in particular to a method for real-time monitoring and identification of the status of indicator lamps of power equipment fault indicators. Background technique [0002] At present, fault indicators for monitoring line faults are installed on the inlet and outlet cables of most electric equipments, and are used to detect the occurrence of faults, the causes of faults, and the lines. However, to read the state of the fault indicator, it is necessary to connect the fault indicator to the processor or controller unit through the field bus technology, use the processor or controller to read the state of the fault indicator, and pass the wired or wireless way To send the read status to the remote control center. This implementation has some disadvantages: [0003] (1) Deficiency in reliability. The processor un...
