Automobile emergency automatic alarm system and method

Abstract

The invention discloses an automobile emergency automatic alarm system and method. The automobile emergency automatic alarm system comprises an automobile driving control unit, a gravity sensor and a relay, wherein the gravity sensor and the relay are connected with the automobile driving control unit. The relay is connected with an alarm device; the gravity sensor collects the acceleration change value of automobile driving in real time and sends the acceleration change value to the automobile driving control unit; the automobile driving control unit sends alarm control signals to the relay after determining that the acceleration change value is larger than a preset automobile acceleration change value; the relay reacts to the alarm control signals to start the alarm device to issue alarm. The automobile emergency automatic alarm system and method can send the alarm control signals to control the relay to start the alarm device to issue alarm when automobile speed jump or emergencies such as tyre burst, turnover and collision occur, so that automobiles at the back can timely find the conditions of ahead automobiles and further heavy losses can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automatic emergency alarm system and method for automobiles. Background technique [0002] In recent years, with the increasing popularity of automobiles, there are more and more vehicles on the road, and the accompanying traffic accidents have also increased. In the event of a tire blowout, rollover, or collision, the speed of the vehicle suddenly dropped. Since the vehicle did not start the warning device in time, or only had a mechanical start-up warning device, and the mechanical switch was unstable and insensitive, when the car rolled over at 360 degrees, its equipment was still Back to the original position, the warning device cannot be activated. Like this, the vehicle running at a high speed in the back often can't be found in time and collides or even many vehicles collide in a row, thereby causing the heavy loss of life and property.

Problems solved by technology

[0002] In recent years, with the increasing popularity of automobiles, there are more and more vehicles on the road, and the accompanying traffic accidents have also increased. In the event of a tire blowout, rollover, or collision, the speed of the vehicle suddenly dropped. Since the vehicle did not start the warning device in time, or only had a mechanical start-up warning device, and the mechanical switch was unstable and insensitive, when the car rolled over at 360 degrees, its equipment was still Back to the original position, the warning device cannot be activated

In this way, the vehicles running at high speed in the back are often unable to be detected in time and collide or even collide with multiple vehicles, resulting in heavy losses of life and property.
