Embodiment Construction

[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] figure 1 It is a schematic diagram of the application scene of an embodiment of the present invention. The smart phone running the driving safety application software is located in the driving car, and is connected to the mobile communication network through a wireless link. The center establishes a communication connection for alarm and self-rescue processing. The smart phone regularly collects GPS position information, vehicle speed, image information in front of the vehicle, and surrounding sound information, etc., and these information can be stored in the built-in memory of the smart phone when the vehicle is running normally; at the same time, the vehicle is monitored through the built-in acceleration sensor The instantaneous acceleration of the vehicle, and through a collision detection algorithm to determine whether a collision...

Abstract

The invention provides a driving safety guaranteeing method based on a smart phone. The method comprises the steps: continuously recording information in front of a travelling vehicle through the smart phone, such as images, surrounding sounds, GPS (Global Positioning System) coordinates, vehicle speeds and the like, monitoring accelerations in three directions through an embedded three-axis acceleration sensor of the smart phone, and comparing the accelerations with a preset alarm threshold and analyzing the acceleration direction to judge whether accident properties such as a collision accident and a collision direction and the like occurs. Alarming for self-rescue is automatically performed once the accident occurrence is judged, and the alarming for self-rescue comprises sending alarm information, automatically calling an alarm centre, uploading critical images and sounds information and the like. The method of the invention is simple to performe without increasing the hardware cost of a user, and applications are installed on the smart phone to realize general functions of a common travelling vehicle recorder and such expanded functions as automatic alarming for self-rescue and remote backup of critical data in the case of danger and the like.

Description

technical field [0001] The invention relates to a driving safety guarantee method, in particular to a method for comprehensively utilizing a smart phone to provide driving safety records and automatic distress alarm. Background technique [0002] With the increasing popularity of cars in ordinary families, the safeguard measures and devices for driving safety have attracted the attention of consumers. For example, the driving recorder that has appeared on the market in recent years integrates functions such as photography, recording, GPS receiver, acceleration sensor, etc., and can completely record information such as the vehicle's driving position track, on-site image, sound, and vehicle speed. , and can be played back and reproduced on the computer through special software. Especially when an accident occurs, the built-in acceleration sensor of the driving recorder will sense emergency braking, sudden impact, etc., and trigger the record to save the situation before and ...
