Method of collision detection and alarm and portable device of collision detection and alarm

Abstract

The present invention provides a method of collision detection and alarm and a portable device of collision detection and alarm. The method of collision detection and alarm comprises: obtaining acceleration magnitudes of a vehicle in x, y and z directions; obtaining a total acceleration magnitude according to the acceleration magnitudes of the vehicle in x, y and z directions; determining whether the total acceleration magnitude is larger than a preset acceleration magnitude or not; shooting driver's images when the total acceleration magnitude is larger than the preset acceleration magnitude; comparing the driver's images with a preset safe driving feature database, and determining whether the driver is in a safe state or not; and sending alarm information when the driver is not in the safe state. According to the invention, the method of collision detection and alarm may be realized through a portable device containing corresponding hardware; and moreover, the method may determine collision and call for help immediately when an accident happens to a vehicle in the prior art not provided with a special alarm device.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a collision detection and alarm method and a portable device. Background technique [0002] With the widespread popularization of automobiles in society, automobile accidents occur frequently, and the number of deaths due to automobile accidents in my country is as high as more than 100,000 every year. In many accidents, the injured are in a coma and cannot be notified in time to the rescue center, resulting in death or aggravated injuries. How to judge the collision at the first time when an accident occurs and notify the rescue center is of great significance to the injured. [0003] Most of the current accident alarm methods are based on the special built-in software and hardware of the car to detect collisions. Although the accuracy is high, the price is expensive. Because of the high installation cost, many cars are not installed. [0004] How to judge the collision a...
