Embodiment 1

[0044] This embodiment discloses a method for detecting and warning an automobile collision, such as image 3 shown, including the following steps:

[0045] S1. Use one or more of accelerometer, gyroscope and geomagnetic sensor to identify the occurrence and degree of vehicle collision;

[0046]S2. Obtain information on the location of the collided vehicle and information on the location of the driving vehicle;

[0047] S3. Collect the information of the collision of the vehicle identified by the collision recognition module and the information of the degree of collision with the information of the location of the collided vehicle obtained by the positioning module and generate alarm information;

[0048] S4. Send an alarm message to a running vehicle equipped with a short-distance radio frequency receiving module within a certain range of the location of the colliding vehicle. The certain range in the present invention refers to the signal that can be transmitted by the shor...

Embodiment 2

[0055] This embodiment discloses a detection and alarm device for automobile collision, such as Figure 4 As shown, including: collision identification module, positioning module, alarm information generation module, short-distance radio frequency transmission module, short-distance radio frequency reception module, OBD interface data reading module, long-distance wireless network communication module, display module, voice module and backup Power supply module, each module is integrated in the device housing, and directly plugged into the OBD interface, and the power is provided by the OBD interface.

Abstract

The invention provides an automobile collision detection and alarm method and a device thereof, belongs to the field of vehicle alarm, and aims at solving the technical problems that accident alarm of existing vehicles is not timely and the risk of serial rear-ended vehicles of the same road segment exists after occurrence of the accident. The technical main points are that the method comprises the steps that one or multiple of an accelerometer, a gyroscope and a geomagnetic sensor is / are applied to identify occurrence of vehicle collision and degree of collision; alarm information is transmitted to a running vehicle internally equipped with a short-distance radio frequency receiving module within a certain range of the position at which the collided vehicle is positioned; the alarm information transmitted by the collided vehicle internally equipped with a short-distance radio frequency transmitting module within the certain range of the position at which the running vehicle is positioned is received; and the alarm information is transmitted to a remote platform by using a long-distance wireless network communication module. The effective alarm information is ensured to be automatically transmitted out within one second after occurrence of the accident so that drivers can be prompted to slow down and give way.

Description

technical field [0001] The invention relates to a collision detection and alarm device, in particular to a vehicle collision detection and alarm device. Background technique [0002] Existing road accident alarm system is generally divided into two modes of manual notification broadcasting station and remote control center control LED traffic guidance display screen. [0003] Manual notification of radio stations (such as figure 1 As shown), the local radio station is generally notified manually by eyewitnesses, and then the radio station notifies the drivers who are listening to the radio by way of broadcast. [0004] The remote control center controls the way of LED traffic guidance display (such as figure 2 As shown), the collision accident alarm information is collected manually or by the collision recognition equipment installed on the vehicle, and sent to the remote control center, and then the on-duty personnel in the control center process the alarm information, a...
