Motor-vehicle accident warning device, system and method

Abstract

The invention relates to a motor-vehicle accident warning device, system and method. The motor-vehicle accident warning device comprises a digital processor, an acceleration sensor, a gyroscope, an OBD connector and a network communication module, wherein the acceleration sensor and the gyroscope are respectively electrically connected with the digital processor, an acquired acceleration magnitude and an acquired magnitude of the angular velocity of a motor-vehicle are input to the digital processor, the OBD connector is electrically connected with the digital processor and an OBD system of the motor-vehicle, information acquired from the OBD system is input to the digital processor, the digital processor is electrically connected with the network communication module, motion information of the motor-vehicle and information of the attitude of the motor-vehicle in space are acquired through calculation according to the information acquired from the OBD system, the acceleration magnitude and the magnitude of the angular velocity, whether motor-vehicle accidents occur or not is judged, and when it is judged that the accidents occur, warning signals and position information of the motor-vehicle are sent through the network communication module.

Description

technical field [0001] The invention relates to the technical field of automobile safety and alarm systems, in particular to an automobile accident alarm device, alarm system and alarm method utilizing existing Internet technology and mobile communication technology. Background technique [0002] Automobile accidents are a leading cause of death. At present, the common automobile accident alarm devices and alarm systems on the market are relatively high-end and expensive, exceeding the tolerance of ordinary consumers. Since there are currently no car accident alarm devices and alarm systems that ordinary consumers can afford, drivers must rely on some emergency alarm service methods that may not be available after the accident to call the police, such as calling the police when an emergency occurs in a car. Call the police. But usually when emergency accident occurs in automobile, it is often difficult for the driver to make a call by himself to report to the police. Con...
