Automobile major accident alarm system and method

Abstract

The invention relates to an automobile major accident alarm system and method. The automobile major accident alarm system comprises an acceleration sensor, a single chip microcomputer, a communicationunit, and an intelligent terminal, wherein the acceleration sensor is used for collecting acceleration data of travelling of an automobile; the single chip microcomputer is used for judging whether the acceleration of the automobile is greater than a threshold value of the acceleration or not and whether the angle of inclination of the automobile is greater than a threshold value of the angle ofinclination or not according to the acceleration data, and determining whether the automobile has a traffic accident or not according to judgment results; and the single chip microcomputer is furtherused for transmitting an alarm trigger signal to the communication unit in the case of determining occurring of the traffic accident; the communication unit is used for sending the alarm trigger signal to the intelligent terminal; and the intelligent terminal is used for obtaining current position information and performing alarm operation when receiving the alarm trigger signal; and as for alarmoperation, the current position information and prestored owner information are sent to a preset emergency contact person and / or an alarm number is dialed. According to the automobile major accident alarm system and method, the functions of real-time accurate positioning, intelligent and diverse alarm for help and the like are realized through the intelligent terminal.

Description

technical field [0001] The invention relates to the technical field of accident alarms, in particular to an alarm system and method for serious automobile accidents. Background technique [0002] With the development of social economy, the per capita ownership of automobiles in China has increased year by year. With the convenience of transportation, the rate of traffic accidents has continued to increase, resulting in a continuous increase in the death rate of traffic accidents. Therefore, it is very important to reduce the death rate of automobile accidents and have a timely and accurate alarm device. [0003] At present, the traditional automobile traffic alarm devices in the domestic market mostly use single-chip microcomputer externally connected to the car's on-board power supply for power supply, and use single-chip microcomputer GPS module for positioning, which generally has the disadvantages of poor positioning failure and low positioning accuracy. Although there ...

Problems solved by technology

[0003] At present, the traditional automobile traffic alarm devices in the domestic market mostly use single-chip microcomputer externally connected to the vehicle-mounted power supply for power supply, and use single-chip microcomputer GPS module for positioning, which generally has the disadvantages of poor positioning failure and low positioning accuracy.

Although there is an emergency help button, it does not consider the problem that the driver is seriously injured and unable to move his hands to operate it

[0004] In conventional traffic accidents, there is a certain delay due to human-made alarms, especially when the car accident occurs in a sparsely populated area and the owner loses the basic operating ability, resulting in unfavorable treatment of the wounded and expanding the scope of the accident, resulting in endangering the lives of the injured. and public building damage

In addition, the current car alarm system generally does not have the function of canceling the alarm, and it cannot be canceled in the case of false triggering.
