Problems solved by technology
[0005] 1) The maintenance personnel arrive at the site and read the data of the instrument or knife switch by visual inspection, but the maintenance cost is very high by manual maintenance;
[0006] 2) Connect the meter / knife switch to the front-end data acquisition unit through physical wiring, and then connect the data acquisition unit to the substation monitoring system, but this method requires physical wiring of the meter / knife switch, but based on the power system Particularity, it is not feasible for substations that have been put into normal use at present, because the transformation action will affect the normal operation of the power system
And for the knife switch, it is not suitable to use physical wiring to collect its data
[0007] 3) Collect the current video data of the instrument / knife switch through the existing video monitoring system, and view the current data of the instrument / knife switch by viewing the video in real time. Although this method greatly saves the cost of on-site maintenance personnel, it cannot To analyze the current operating status of the system, maintenance personnel need to frequently record the data in the video and analyze it based on these data to make judgments. To a certain extent, the workload of maintenance personnel is still relatively large
[0008] In summary, the traditional substation monitoring methods have certain limitations.

The invention discloses a method, a device and a system for substation monitoring. The method comprises steps: a video image of an instrument / isolator object is acquired; current instrument / isolator data are recognized in the video image; and alarming information is generated according to the current instrument / isolator data and at least one preset alarming strategy. Through associating the video camera and the instrument / isolator object, after the instrument / isolator data are recognized automatically based on a video analysis technology, the analyzed instrument / isolator data are thus subjected to high-level business processing, the alarming information is generated according to the current instrument / isolator data and the preset alarming strategy, the workload of a maintenance staff of the substation can be reduced, and the maintenance efficiency of the substation monitoring system is improved.
Description
technical field [0001] The present invention relates to the technical field of monitoring, in particular to a substation monitoring method, device and system. Background technique [0002] Substation monitoring is aimed at the use characteristics of users in the power industry, combined with industrial control, security management and digital video, etc., using the existing network resources of the power grid to design a set of remote viewing system, access control system, fire protection system, environment and power monitoring system. Networked integrated security management system. [0003] In substation monitoring, digital instrument data, pointer instrument data and knife switch data are very important technical indicators in the operation and maintenance process of substation monitoring system. For example: Substation users can judge the current operating status of power equipment through digital or pointer instrument data, and judge whether the system is faulty based...
