Abstract

The invention relates to an intelligent voice prompt method for train fault and operation guidance, and belongs to the technical field of rail transit industry. The method comprises the following steps: (1) a loudspeaker is arranged on a driver display unit HMI on the train; (2) through intelligent voice synthesis, the fault name and the operation and maintenance text information are synthesized into a voice file in real time, and voice playing is carried out through a loudspeaker; (3) and adding a voice playing selection button on the HMI to perform automatic or manual voice playing. The invention enables a driver to master the train fault information at the first time; when troubleshooting is carried out, operation and maintenance personnel listen to troubleshooting steps or operation suggestions while processing faults, and therefore the fault processing efficiency is improved.

Description

Intelligent voice prompt method for train fault and operation guidance

The technical field is as follows:

the invention relates to an intelligent voice prompt method for train fault and operation guidance, and belongs to the technical field of rail transit industry.

Background

At present, the common practice in the rail transit industry is to perform fault word prompt and buzzer alarm through an HMI (human-computer interface) when a train breaks down, and when a driver pays attention to the situation before the train runs, the fault information of the HMI screen cannot be checked. When the number of fault processing steps is large, the operation and maintenance suggestions are read in a long time.

In the prior rail transit industry, when a vehicle breaks down, a buzzer alarms and cannot prompt a driver of specific fault information, and the vehicle needs to be parked and then is checked on a corresponding interface in an HMI (human machine interface), so that time delay is caused for fault removal; when the number of fault processing steps is large, the operation and maintenance personnel spend more time reading the operation and maintenance suggestions during the troubleshooting process, the omission is easy, and the troubleshooting efficiency is low.

Disclosure of Invention

The invention provides an intelligent voice prompt method for train fault and operation guidance, when a train has a fault, fault information is automatically played in a voice mode through a driver display unit HMI, so that a driver can master the train fault information at the first time, and the fault emergency disposal efficiency is improved; when troubleshooting is carried out, operation and maintenance personnel can play the operation suggestions through the voice playing function, listen to troubleshooting steps or operation suggestions while processing faults, and improve the fault processing efficiency.

The invention adopts the following technical scheme for solving the technical problems:

an intelligent voice prompt method for train fault and operation guidance comprises the following steps:

(1) a loudspeaker is arranged on a driver display unit HMI on the train;

(2) through intelligent voice synthesis, the fault name and the operation and maintenance text information are synthesized into a voice file in real time, and voice playing is carried out through a loudspeaker;

(3) and adding a voice playing selection button on the HMI to perform automatic or manual voice playing.

The specific process in the step (2) is as follows:

when the train breaks down, the driver display unit HMI automatically carries out voice playing on the fault information; when operation and maintenance personnel carry out troubleshooting, the driver display unit HMI automatically plays failure information and troubleshooting operation suggestions.

And (3) the intelligent voice synthesis software in the step (2) is Qt C + + software.

The invention has the following beneficial effects:

according to the invention, by integrating an intelligent voice synthesis function on the HMI, when a fault occurs, the HMI automatically synthesizes character information of a corresponding fault item into a playable audio file to play, and the audio file is automatically deleted after playing is finished.

The invention supports the selection of a fault voice playing mode, and operation and maintenance personnel can select two modes of automatic playing and non-automatic playing on the HMI, wherein the automatic playing mode is to automatically play the fault name when a new fault occurs in the train, and the manual playing mode is to click a manual playing button after a certain fault item is selected, so that the HMI plays the fault processing suggestion.

Fig. 3 is a flow chart of the process of automatically playing speech.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings.

As shown in fig. 1, the current fault interface provides buttons for automatic broadcasting and manual broadcasting, and is used for voice broadcasting of fault prompt information, wherein the automatic broadcasting is a self-locking button, and the manual broadcasting is a self-resetting button. The HMI power-on defaults to an automatic play mode.

When the type of the equipment is selected, an HMI with a speaker needs to be selected, and fig. 2 is an appearance schematic diagram of a display screen of a No. 5 Hangzhou line.

The HMI realizes the function of intelligent speech synthesis and playing through software, and the specific flow is shown in fig. 3.

A new queue (first in first out) in the HMI is used for storing the current fault of the train, and when the HMI monitors that the fault occurs, the fault is added into a fault list. And newly establishing an audio processing thread, performing voice synthesis and playing on the failure information which occurs firstly in the list when the failure list is not empty and no audio is currently played, and moving the failure out of the failure list. And when the HMI monitors that the faults waiting in the list disappear, the faults are moved out of the list. And after the fault voice is played, the HMI automatically deletes the synthesized audio file.

When a maintainer processes a certain fault, the maintenance personal can cancel the automatic playing mode by clicking an automatic playing button on the HMI, click a manual playing button after selecting a certain fault, the HMI synthesizes the processing opinions corresponding to the fault into an audio file and plays the audio file, and the synthesized audio file is automatically deleted after the playing is finished.

HMI software is developed by using Qt C + +, and a specific software implementation method for voice playing comprises the following steps: and a structure body queue is newly established for storing fault information, and the structure body comprises information such as fault ID, fault name, fault grade, fault processing method and fault occurrence time. When the HMI is in an automatic playing mode, the fault grade of the new fault is stored in a list, the position corresponding to the fault with the highest fault grade and the earliest occurrence time is found, the fault information of the position is obtained, and the fault name text is subjected to voice conversion and played.

And deleting the fault information from the queue after the playing is finished. When the playing mode is switched from automatic playing to manual playing, the queue is emptied. When the HMI is in a manual broadcasting mode, a program acquires the fault ID of the selected current fault item in real time, when an operator clicks a broadcasting button, the information of a fault name, a fault grade, a fault processing method, fault occurrence time and the like corresponding to the fault is acquired, the fault information is added into a fault broadcasting queue, the text of the fault processing step is subjected to voice conversion and is broadcasted, and the broadcasting queue is emptied after the broadcasting is finished.
