Problems solved by technology
The advantage lies in the robustness of the algorithm, but the amount of parameters in the model is huge, and the inference time on the embedded device is relatively long. At the same time, when identifying the state of the pressure plate, it only uses the characteristics of the current platen image, and does not refer to the historical platen image and status.
[0008] It can be seen from the above that most of the existing identification methods for the switch-in and withdrawal status of the pressure plate need to modify the protective screen, or are sensitive to environmental changes, or the identification time is long, and it is difficult to apply to the substation system

The invention discloses embedded relay protection pressing plate on-off state identification method and device, and belongs to the field of deep learning and power system protection. The device comprises an embedded image acquisition module, a pressing plate position detection module, a pressing plate on-off state identification module, an identification result output module and a local storage module. The embedded image acquisition module is used for shooting a relay protection screen image containing a pressing plate, wherein the pressing plate is positioned through the pressing plate position detection module, and a positioning area is cut and sent to the pressing plate switching state recognition module to acquire a switching state recognition result is obtained; the recognition result is displayed through the output module, and the result is stored in the local storage module. Therefore, the pressing plate can be quickly and accurately positioned, the on-off state of the pressing plate can be recognized, and the operation and maintenance intelligence of the power transformation equipment is improved, so that the dependence of manual inspection is reduced, the influence caused by shooting angle change, illumination intensity change and the like can be effectively reduced, and the method has very high robustness and adaptability to different application scenes.
Description
technical field [0001] The invention belongs to the field of deep learning and power system protection, as well as the field of intelligent image recognition technology, in particular to a method and device for identifying the switching state of an embedded relay protection pressure plate. Background technique [0002] With the increasing scale of my country's power grid, on the one hand, the ability to optimize the allocation of power resources has been improved, and on the other hand, it has also brought challenges to the operation and control of the power grid. As a key link in the power transmission process, the relay protection system is closely related to software, information, and equipment. It has the characteristics of state diversity and information transmission interleaving. Hidden dangers in any link will pose a threat to the safe and stable operation of the power grid. The relay protection pressure plate has obvious breakpoints, which can accurately distinguish ...
