Automatic passenger and driving safety alarm device based on intelligent voice recognition and method thereof

Abstract

The invention discloses an automatic passenger and driving safety alarm device based on intelligent voice recognition. The voice data in a vehicle are collected in real time through a multi-path microphone pickup circuit, the device collects audio data in the vehicle in real time, and the audio is subjected to amplification filtering and voice extraction after preprocessing, and real-time communication is carried out with the cloud background through a wireless communication module. The invention further provides an automatic passenger and driving safety alarm method based on intelligent voicerecognition. The voice data are subjected to preprocessing and then are sent for feature extraction, the voice is transmitted to an acoustic model for comparison. If the voice falls into the alarm preset sensitive words, the alarm text information is output to the background, and the background is fed back to an online ride-hailing platform, so that the abnormal situation can be immediately processed. The safety supervision black hole of current online ride-hailing is reduced. The life and the safety of people in the vehicle can be guaranteed, voice communication can be directly carried out with a party involved, and illegal criminals of online ride-hailing can be effectively reduced.

Description

Technical field [0001] The invention relates to the technical field of ride safety equipment, in particular to a ride safety automatic alarm device and method based on intelligent voice recognition. Background technique [0002] Currently, online car-hailing safety accidents are frequent, the base of online car-hailing is large, illegal accidents happen without warning, the safety technology of online car-hailing platform is limited, and there is a serious lag, which leads to accidents even if the victim is alert and alarms. Receiving the alarm is delayed and difficult to deal with. The current accident exception handling mechanism of the online car-hailing platform is to connect the call or send a text message to the contact platform through the emergency contact or distress call on the mobile APP when the victim feels the threat in advance; based on this mechanism, on the one hand, it is illegal and criminal When the event occurred, the victim was limited by the environment at...

AI Technical Summary

Problems solved by technology

[0003] 1) The online car-hailing platform has a large base, and the online car-hailing platform cannot obtain the real-time situation of each vehicle. The supervision workload is heavy and there are omissions to call for help vehicles;

[0004] 2) The safety prevention mechanism of the online car-hailing platform is unfavorable. The platform has layers of approvals for accident alarm handling and vehicle information monitoring, and the internal supervision process leads to delays in the police's immediate disposal;

[0005] 3) The technical supervision of online car-hailing can only provide the general characteristics of the vehicle and GPS location information, and passively receive the reporting information provided by the reporter

Due to technical defects, regulatory loopholes cannot be stopped immediately when the case occurs, which also encourages the chances of criminals and directly causes harm to the lives of victims.
