Power grid fault information remote transmission system and method based on camera technology

Abstract

The invention provides a power grid fault information remote transmission system based on a camera shooting technology. The power grid fault information remote transmission system comprises an information acquisition and display device and a camera shooting device nearby a specified power grid device and an information processing server at the far end of the specified power grid device, the information acquisition and display device periodically detects the fault information outputted by the specified power grid device, hibernates the display performance when the fault information is not detected, and awakens the display performance and displays when the fault information is detected, the camera shooting device closes the camera shooting acquisition performance when the display performanceof the information acquisition and display device is dormant, starts the camera shooting acquisition performance to perform camera shooting acquisition when the display performance of the informationacquisition and display device is awakened, and performs real-time output, and the information processing server stores the shot and acquired images or / and videos, and performs query and classification processing. By implementing the invention, manual intervention is reduced, and the automatic remote transmission function of the power grid fault information is realized, so that the problems of the existing power grid fault information acquisition method are solved, and the power supply reliability is improved.

Description

technical field [0001] The invention relates to the technical field of power system fault detection, in particular to a remote transmission system and method for power grid fault information based on camera technology. Background technique [0002] With the development of the power system, the power load center and the power generation center are often not in the same place. However, in order to balance economy and safety, it is necessary to connect distant substations or power plants through transmission lines for power transmission. Therefore, once a grid fault exists, fault analysis is often difficult, especially for remote faults. [0003] When analyzing power grid faults, it is necessary to understand the whole process before and after the fault as soon as possible to judge the type of accident, so as to quickly judge the severity of the fault through the type of fault, which is also conducive to analysis and quick finding of fault points, and speed up the rapid restora...

AI Technical Summary

Problems solved by technology

For example, after manually going to the substation or power plant to print on-site, then make a detailed summary and report to the relevant management personnel, but this method takes a long time, especially for remote unattended substations, which may take up to several hours or even longer. For a long time, it is extremely unfavorable to improve the rapid power recovery rate and power supply reliability, and waste a lot of manpower and material resources; another example is to use the method of printing power grid fault information on paper, but this method is not environmentally friendly and cannot be electronically archived and transmitted. It not only wastes a lot of consumables such as paper and ink, but also causes high maintenance costs and heavy workload for the printer. Another example is that the fault information collection and transmission technology developed by some universities and scientific research institutions involves the conversion of collection protocols during network transmission. Collect the protection protocol conversion protocol of each manufacturer, but it is difficult to realize the real collection, and there is no obvious isolation point because of the direct connection with the power grid system, and there are network security problems, which makes it extremely difficult to promote and apply
