Problems solved by technology

[0006] However, during the use of the train operation control system, the driver of the locomotive cab needs to speak different standard voice commands at different time points during the driving process. Voice commands are monitored to further regulate the driver's operating behavior during driving
In this way, the driver is prone to irregular operations during driving, thereby increasing the risk of locomotive driving

Abstract

The invention discloses a locomotive driver operation standard voice recognition device, which comprises a pickup, a loudspeaker and a hardware computing platform. The pickup collects voice data of alocomotive cab, the loudspeaker broadcasts voice to feed back a driver, and the hardware computing platform comprises a voice processing unit, a storage unit and a communication unit. The voice processing unit comprises a feature extraction module and a voice recognition module, the storage unit stores a voice recognition result of the voice recognition step and related data of the voice recognition result, and the communication unit is used for realizing communication between the hardware computing platform and external equipment.

Description

technical field [0001] The patent of the present invention relates to the technical field of voice recognition, in particular to a standard voice recognition device for drivers in locomotive cabs. Background technique [0002] The train operation control system, referred to as train control, is a system to ensure the safe and fast operation of trains. The main function of the train operation control system is to complete the interval control and speed control of the train. A complete train operation control system should include on-board equipment and ground equipment. [0003] The locomotive signal, train automatic parking device, and train wireless dispatching telephone are collectively referred to as the "three major parts of the locomotive". Since the 1980s, it has been rapidly popularized in my country's railways. They play a significant role in ensuring traffic safety and improving transportation efficiency, and they are also the starting point of my country's train...
