Abstract

The invention discloses an automobile accident noise detection and positioning system based on a sound sensor. The automobile accident noise detection and positioning system comprises a vehicle-mounted data acquisition and positioning module and a remote monitoring terminal, wherein the remote monitoring terminal is connected with the data acquisition and positioning module; the data acquisition and positioning module comprises a sound sensor, a data processing module, an AD converter, an amplifier module, a wireless communication module, a positioning module and a power supply module; the wireless communication module comprises a single chip microcomputer module and a GPRS wireless communication module which is connected with the single chip microcomputer module. Due to adoption of the sound sensor, noise generated when automobiles collide with each other can be acquired in real time, acquired noise parameters and position information can be transmitted to the remote monitoring terminal in real time, the remote monitoring terminal can acquire the place of the automobile accident in time, rescue assistants can be sent in time, meanwhile, help calling can be transmitted to 911, emergent contact persons and the like, and injuries and deaths caused by salvage delay on sparsely populated roads can be prevented.

Description

technical field [0001] The invention relates to a vehicle collision detection system, in particular to a vehicle accident noise detection and positioning system based on an acoustic sensor, and belongs to the technical field of vehicle automatic detection. Background technique [0002] One of the goals pursued by the automotive industry is to maximize the safety of drivers and passengers in the event of an accidental collision. According to statistics from the Ministry of Health of my country, only 14.3% of the 1,000 traffic accident victims can reach the hospital in time by ambulance. Road traffic accidents show that if emergency rescue measures are adopted within 5 minutes of the traffic accident and emergency treatment is used within 30 mm, at least 18% to 25% of the seriously injured can be saved from death; in addition, about 40% of the traffic accident deaths in my country The injured died on the spot, and the remaining 60% died in the hospital or on the way to the hos...
