Device and method for detecting vehicle collision rolling over and automatically calling for help

Abstract

The invention discloses a device and method for detecting vehicle collision rolling over and automatically calling for help. The device comprises a vehicle-mounted front end, a communication network and a monitoring terminal. The vehicle-mounted front end comprises an MCU, an acceleration sensing unit, a vehicle state monitoring unit, a BD / GPS receiving unit, an input and output module and a GPRS module. The monitoring terminal comprises a plurality of client sides for performing monitoring, and the vehicle-mounted front end is connected with the monitoring terminal through the communication network. The types, the serious degree and the direction of a possible driving fault are preliminarily judged by utilizing variation between the acceleration subjected by a vehicle when the fault happens and the acceleration subjected by the vehicle under the normal condition according to the happening duration, the direction, the degree, the changing history and characteristics of the variation. The problems that a traditional vehicle-mounted device cannot give an alarm remotely, and data collecting and data analyzing cannot be carried out when an accident happens are solved.

Description

technical field [0001] The invention relates to a vehicle-mounted device, in particular to a device and method for automatically calling for help based on vehicle collision and rollover detection. Background technique [0002] With the rapid development of social economy, the use of cars has greatly facilitated people's daily life. However, with the continuous increase of the number of cars, the frequent traffic accidents it brings seriously threaten people's lives and property safety. Therefore, discovering and handling traffic accidents in time is an important guarantee for protecting the safety of people's lives and property. In order to better protect the safety of people in the car, many foreign automakers have invested a lot of manpower and material resources in recent years to develop automatic emergency call systems for vehicle accidents, but they are generally triggered based on automatic triggering of airbags or manual buttons. When the airbag sends out a distress...
