In-vehicle safety monitoring and help seeking system based on automobile data recorder and crying recognition

Abstract

The invention belongs to the technical field of safety monitoring, and discloses an in-vehicle safety monitoring and help seeking system based on an automobile data recorder and crying recognition. The system comprises an audio input module which is used for collecting a basic cry sample, wherein when an automobile flames out, the automobile data recorder triggers a parking monitoring state, a child safety monitoring help seeking system is started, and a built-in audio receiver receives a sound signal, carries out audio segmentation processing and stores audio clips, and a voice recognition module carries out next-step recognition; the voice recognition module which is used for confirming and recognizing the acquired audio signal; and a signal sending module which is used for sending a help seeking message to a vehicle owner through a wireless network of the automobile data recorder so as to complete the external output function of the help seeking signal. According to the invention, the automobile data recorder widely used in the existing automobile or school bus is fully utilized, a mobile phone dialing system and a crying recognition system are integrated, and the system can beintegrated with the Internet of Vehicles, so that corresponding responsible persons can be timely notified when crying occurs, so that trapped infants in the automobile can be timely discovered.

Description

technical field [0001] The invention belongs to the technical field of safety monitoring, in particular to an in-vehicle safety monitoring and help-calling system based on a driving recorder and cry recognition. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: in recent years, some infants and young children have been trapped in cars and fatal incidents have occurred frequently. Even when the outdoor temperature is 20 degrees, the temperature inside the closed car can be as high as 46 degrees, which is undoubtedly fatal to infants who are unable to call for help. At the same time, because the environment inside the car is too closed, the outside world cannot hear the child's long-term crying, so the chance of survival is low. Therefore, the child safety monitoring system in the car has become an important part of the car safety construction and operation. At present, the design and construction for the safety of...

AI Technical Summary

Problems solved by technology

[0004] (1) The accuracy of judging the dangerous situation of young children is low for cars with an in-car alarm device for accidental locking of infants

[0005] (2) The existing technologies all use multiple sensors or single-chip microcomputers to work together to achieve detection, and the cost is relatively high

[0006] (3) The existing technology cannot accurately distinguish children from adults, and there are often false positives

[0007] (4) The existing technology occupies a small space in the car, which makes the interior of the car more crowded and the user experience is reduced
