Method and device used for vehicle collision/side overturn detecting and alarming

Abstract

The invention discloses a method for checking and alarming vehicle impact / turnover, and a relative device. Based on the difference between the acceleration of vehicle at accident and the normal acceleration, and the time, direction and volume of the difference, and the history and character of the difference, the invention can primarily judge the type, level and direction of driving accident, sum prior state and driving state history record of the vehicle, to analyze the reason and process of driving accident, thereby checking and alarming vehicle impact / turnover. The invention has simple installment, easy application, and low cost. The invention has remote-alarm function.

Description

technical field [0001] The invention relates to a method and device for vehicle collision / rollover detection and alarm. Background technique [0002] With the rapid development of my country's national economy and the substantial improvement of people's living standards, the number of vehicles in our country has increased significantly. On the one hand, the increase in vehicles has brought great convenience to people's travel, and on the other hand has brought Some disadvantages, such as causing traffic congestion, etc., but more importantly, have increased many potential safety hazards. Therefore, timely discovery and handling of traffic accidents is an important guarantee for protecting people's lives and property. With the advancement of science and technology, detection, protection and alarm systems for collisions and rollovers are generally installed on vehicles today. The detection, protection and alarm systems usually include an acceleration sensing unit, a vehicle sta...

[0002]With the rapid development of my country's national economy and the substantial improvement of people's living standards, the number of vehicles in our country is increasing significantly. It has brought great convenience, but on the other hand it has also brought some disadvantages, such as causing traffic congestion, etc., but more importantly, it has increased many potential safety hazards. An important guarantee for the safety of people's lives and property

With the advancement of science and technology, detection, protection and alarm systems for collisions and rollovers are generally installed on vehicles today. The detection, protection and alarm systems usually include an acceleration sensing unit, a vehicle state detection unit, a Detection alarm control unit, a signal transmission unit, a GPS receiving unit, a vehicle alarm display unit, a vehicle remote alarm unit, a remote monitoring terminal, the traditional system is arranged and set so that when the vehicle collides or rolls over, it can Timely alarm and trigger the necessary protection mechanism to protect the safety of personnel in the vehicle, and send alarm information to the remote monitoring terminal at the same time, however, the existing detection, protection and alarm systems still have the following drawbacks; one is in the existing In the system, whether a mechanical acceleration sensing unit or a mechanical transmission mechanism is used to detect collisions and rollovers, each sensing unit or mechanical transmission mechanism has a single and independent function, that is, two or more sensing units or mechanical transmission mechanisms may be required It is difficult to install and realize various signal detections such as collision, rollover, lateral sliding, and lateral acceleration, and the cost is high; secondly, in the existing system, the detection unit cannot transmit various driving faults or The implementation is extremely complicated; the third is that in the existing system, the alarm unit, as a part of the safety protection unit, only expresses the fault signal at the place where the fault occurs, but in most cases, the on-site situation of the fault depends on the site eyewitness reports
