Vehicle-mounted highway accident early-warning device and highway accident early-warning device

Abstract

The invention discloses a vehicle-mounted highway accident early-warning device, and the device comprises a first wireless receiving and transmitting module which is used for receiving a gateway entrance code of a highway and an SIM card number of a GSM module of a highway traffic police monitoring center; a vehicle-mounted GPS module which is used for obtaining the position information of a vehicle; a vehicle-mounted GSM module which is used for communication with the highway traffic police monitoring center according to the SIM card number; a second wireless receiving and transmitting module which is used for transmitting position information and the gateway entrance code to surrounding vehicles during an accident, and receiving the position information and gateway entrance codes of other vehicles with an accident when there is no accident; and a controller which is connected with the first wireless receiving and transmitting module, the vehicle-mounted GPS module, the vehicle-mounted GSM module and the second wireless receiving and transmitting module, and transmits the gateway entrance code and position information to the highway traffic police monitoring center through the vehicle-mounted GSM module during the accident. The device achieves the detection and early warning of a highway traffic accident, and effectively prevents a secondary accident.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle-mounted highway accident warning device, a highway accident warning device and a highway accident detection and warning system. Background technique [0002] With the development of the economy and the improvement of people's living standards, the number of cars in my country continues to increase, and the total mileage of expressways is also increasing. At present, the total mileage of expressways in my country ranks second in the world after the United States, and third in the world than Canada. Double the mileage. Due to the rapid increase in the number of vehicles and the total mileage of expressways, the development of intelligent transportation systems is slow, and there is no intelligent information-based traffic management system for detection and prevention of traffic accidents. There is no early warning mechanism for traffic accidents, and accident handlin...
