Pantograph abnormal descending judgment method and device, electronic equipment and rail vehicle

The invention provides a method and a device for judging abnormal descending of a pantograph, electronic equipment and a railway vehicle. The method comprises the following steps: collecting a pantograph rising relay signal and a pantograph pressure switch relay signal; according to the pantograph rising relay signal and the pantograph pressure switch relay signal, judging whether the pantograph descends abnormally or not. According to the method and the device for judging the abnormal descending of the pantograph, the electronic equipment and the storage medium provided by the invention, the abnormal descending phenomenon of the pantograph is judged timely and accurately by integrating the pantograph rising relay signal and the pantograph pressure switch relay signal, the situation that the operation order is affected due to the fact that the pantograph abnormally descends in the operation process of the railway vehicle cannot be found in time is prevented, and the safe, reliable and punctual operation of th
