Abstract

The invention relates to a time synchronizing system and method for a haulage motor recording device and an LKJ. The time synchronizing system comprises the steps that a voice signal input by the haulage motor recording device is received, and a voice prompt signal emitted by the LKJ is collected from the voice signal; endpoint detection and feature extraction are carried out on the input voice signal and the voice prompt signal; features of the voice prompt signal are trained, features of the input voice signal and a training module are matched and recognized, the voice prompt signal of the input voice signal is recognized, and a moment of the voice prompt signal in a recording record is recognized; finally, the moment of the voice prompt signal in the detected recording record is synchronized with a moment of the voice prompt signal in an LKJ operation record document, and then the time synchronization between the haulage motor recording device and the LKJ is achieved. The synchronization between the two devices is achieved in a voice signal treatment mode, the timing time and difficulty is greatly reduced on the basis of not adding the cost of a recording device.

Description

technical field [0001] The invention relates to a time synchronization system and method between a locomotive recording device and an LKJ monitoring device, belonging to the technical field of voice signal processing. Background technique [0002] In order to enhance the locomotive driver's awareness of standardized operations and ensure the safe operation of the locomotive, each locomotive driver will be equipped with a locomotive recording device to record the call response, locomotive joint control and other voice operations during the locomotive operation. LKJ is a train operation monitoring and recording device, which is a domestic train overspeed protection equipment. It can accurately record the train operation status, signal equipment status and crew operation status, and adopts the dual-machine hot standby redundant working mode, and the working performance is more reliable; the device’s The screen display shows information such as the status of the line in front, t...
