Abstract

The invention provides an overturning alarm method and device for a car networking embedded system. The overturning alarm method comprises the steps that S1 an ARM mainboard detects that a vehicle turns over and triggers an overturning warning; S2 an alarm module produces a protocol packet and sends the protocol packet to a network module, and the network module sends the warning protocol packet to a mobile phone APP or an external server; and S3 GPS hardware acquires the GPS coordinate of the vehicle and sends the coordinate and the final location of the vehicle to the mobile phone APP or theexternal server. According to the invention, vehicle overturning can be promptly notified to the owner of the vehicle or drivers through the mobile phone APP or a short message; the overturning location of the vehicle and the final destination of the vehicle can be accurately recorded; and the vehicle which turns over can be immediately turned off and stopped to prevent the vehicle from gliding far away, which reduces losses and hazards.

Description

technical field [0001] The invention relates to an alarm system, in particular to a vehicle rollover alarm method and device for an embedded system of the Internet of Vehicles. Background technique [0002] From 1992 to 1996, there were as many as 22,700 car rollover accidents in the United States every year, second only to frontal collisions. With the growth of the number of cars in China, such accidents will also increase accordingly. Therefore, it is very necessary to study the rollover warning system. The traditional rollover sensor is based on gyroscopes, and the system is cumbersome and complicated, which seriously affects its popularization. And still exist in the prior art after the rollover alarm occurs, the car owner and the riders cannot be notified in time; after the rollover, the vehicle rollover location cannot be tracked; Contents of the invention [0003] In order to solve the above problems, the present invention provides a vehicle rollover alarm method ...
