Vehicle collision wireless detection and alarm device and method based on vehicle dashboard data collector

Abstract

The invention discloses a vehicle collision wireless detection and alarm device and a vehicle collision wireless detection and alarm method based on a data acquisition device of an automobile instrument panel, belongs to the vehicle alarm field and aims to solve the technical problem that vehicles on the same road section still have a chain rear-end collision risk as an existing vehicle does timely alarm after an accident. According to the technical key point, the method comprises the following steps: using one or more of an accelerometer, a gyroscope and a geomagnetic sensor to identify occurrence and collision degree of vehicle collision; issuing alarm information to a travelling vehicle in which a short-distance radio frequency receiving module is mounted within a certain range of the location of the vehicle in collision; receiving alarm information issued by the vehicle in collision with the short-distance radio frequency receiving module within a certain range of the location of the travelling vehicle; and issuing alarm information to a remote platform by a long-distance wireless network communication module. According to the vehicle collision wireless detection and alarm method, effective alarm information is guaranteed to be automatically and effectively issued within one second after the accident happens, so that a driver is reminded to decelerate and avoid collision.

Description

technical field [0001] The invention relates to a collision wireless alarm device, in particular to a wireless alarm device for automobile collision and a method thereof. 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 broadcasting 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...

AI Technical Summary

Problems solved by technology

[0008] Existing car data collectors generally obtain car bus data by communicating with the car bus, or obtain data information generated during vehicle driving through indirect communication with the car bus through the OBD diagnostic interface. The way of vehicle bus communication is limited by the function of the in-vehicle diagnostic interface, and only part of the information supported by the diagnostic interface can be read

[0009] Since the existing collectors that communicate with the bus need to communicate with the bus in the vehicle in a polling manner, this acquisition method is limited by the communication delay of the bus, and there is a possibility of information loss in vehicle data acquisition
