Rail transit tunnel high-speed train number identification system

Abstract

The application discloses a rail transit tunnel high-speed train number recognition system, and relates to the field of train number recognition. The system comprises: a shock-absorbing holder fixed on a tunnel side wall support on one side of a high-speed train track; a multi-angle base installed on the shock-absorbing holder in a preset installation mode; a train number recognition unit fixedly arranged on the multi-angle base; a pressure sensor arranged on the track of the high-speed train, the pressure sensor being electrically connected with the train number recognition unit; and a host computer electrically connected with the train number recognition unit. After the high-speed train passes and triggers the pressure sensor, the train number recognition unit takes a photo of the high-speed train after quickly supplementing light, and the host computer identifies the train number of the high-speed train according to the photo. The application solves the problem of reflection interference of a traditional camera in shooting of a high-speed moving object in a dark tunnel environment, reduces the influence of vibration generated when the train passes on shooting, and improves the accuracy, reliability and universality of train number recognition in a poor tunnel environment.
