Embodiment Construction

[0019] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0020] Such as figure 1 Shown, a kind of automatic positioning alarm system for car accidents based on acceleration includes a microcontroller module and an acceleration detection module connected with the microcontroller module, a communication module, and a positioning module; Differential capacitors, modulators, filters, and duty ratio modulators, the microcontroller module includes a calculation unit, a comparison unit and a control unit; under the action of acceleration, the polysilicon structure produces an offset to make the capacitance value of the differential capacitor Change, the change signal of the differential capacitor is demodulated by the modulator and then transmitted to the duty ratio modulator through the filter to be converted into a square wave whose duty ratio is proportional to the acceleration. The calculation unit calculat...

Abstract

The invention discloses an acceleration based automatic locating and alarming system for a traffic accident. The system is that the acceleration is determined on real time, the longitude and latitude are displayed on real time, and the function of automatically sending information is performed. According to the system, the GPS and the GSM are adopted to provide a complete data communication platform to reach the purpose of automatically locating and alarming, and therefore, the death due to delayed rescue can be greatly reduced.

Description

technical field [0001] The invention relates to an acceleration detection system, in particular to an acceleration-based automatic positioning and alarm system for car accidents, belonging to the technical field of automatic vehicle 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 injured in traffic accidents can reach the hospital by ambulance in time. 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 injured in traffic accident deaths in my country The remaining 60% died in the hospital or on the way to the hospital, and 30% of the injured di...
