A method and system for intelligent station announcement verification based on moving image recognition

Abstract

The present invention proposes an intelligent station announcement verification method based on moving image recognition. Firstly, the train speed and acceleration are detected, and in response to the train speed and acceleration meeting the first setting condition, the image acquisition terminal is triggered to obtain the train's traveling process. image; in response to the train speed and acceleration meeting the second set condition, stop the image acquisition operation to obtain the image set; input the image set into the trained neural network model to predict the arrival site; combine the predicted arrival site with the pre-stored The arrival site in the voice broadcast is matched to complete the verification; the method provided by the invention can carry out deep neural network learning according to the collected images, predict the arrival site in advance, and perform mutual verification with the voice broadcast site to avoid communication failures The station reporting errors caused by the system improve the reliability of the station reporting system.

Description

technical field [0001] The present invention relates to the field of train station announcement, in particular to an intelligent station announcement verification method and system based on moving image recognition. Background technique [0002] At present, the subway signal system uses the automatic train control system based on communication. The subway station announcement system is a part of this system, which is supported and operated by this system. The subway train operation is controlled by computer and runs strictly according to the speed curve to achieve high accuracy. Therefore, for the daily operation planning of the subway, the subway trains strictly follow the operation timetable, that is, when the train is running on the main line, a specific time in the timetable corresponds to the corresponding stop station, and the operation control of the subway The center plans the running timetable in a unified way, and sends it to each train through the wireless communi...

Problems solved by technology

[0003] However, once a communication failure occurs, the train station reporting system will have accidents such as station reporting errors and no station reporting. In the current PIS system, station reporting methods are divided into ATS station reporting, semi-automatic station reporting, manual station reporting, or relying on TMS. Data, or manual operation, the two cannot be mutually verified, and it is easy to cause other operational accidents
