The present application discloses an overvoltage signal identification method, device and medium, wherein the method includes: acquiring a target voltage signal, and in the case that the target voltage signal is an overvoltage signal, extracting characteristic data of the target voltage signal, and determining according to the characteristic data Type of target voltage signal. After detecting that the target voltage signal is an overvoltage signal, the overvoltage type of the target voltage signal is determined according to the characteristic data of the target voltage signal, so the overvoltage can be dealt with in a targeted manner when the overvoltage is dealt with subsequently, which improves the overvoltage processing efficiency. Targeted and accurate. In addition, the present application discloses an overvoltage signal identification device and a medium, which correspond to the above overvoltage signal identification method and have the same effects as above.
Description
technical field [0001] The present application relates to the technical field of signal identification, and in particular, to an overvoltage signal identification method, device, medium and vehicle. Background technique [0002] With the development of science and technology, railways have become an important part of long-distance transportation and an indispensable part of human life. With the rapid development of electrified railways, the problem of overvoltage in the traction power supply system affects the stable operation of the railway system. [0003] The existing overvoltage online monitoring device for traction power supply system can only detect overvoltage, but cannot analyze the type of overvoltage signal, so it cannot accurately and timely determine the type of overvoltage of the EMU, resulting in the lack of pertinence in overvoltage troubleshooting. [0004] It can be seen that how to improve the pertinence and accuracy of fault handling is an urgent problem ...
