Vehicle-mounted communication device and method based on DSRC and Beidou satellite

Abstract

The invention provides a vehicle-mounted communication device and method based on the DSRC and Beidou satellite and belongs to the technical field of vehicle-mounted communication technology. The device comprises a Beidou satellite positioning unit, a wireless transmitting and receiving unit, a vehicle-mounted processing unit and a touch displaying unit. The Beidou satellite positioning unit is used for acquiring the vehicle location information and transmitting and receiving short messages; the wireless transmitting and receiving unit is used for transmitting or receiving vehicle-vehicle or vehicle-road data packages; the vehicle-mounted processing unit is used for processing and predicating the location and speed information of the vehicle currently so as to judge whether the colliding risk exits or not, if yes, the vehicle-mounted processing unit alarms or reminds a user; the touch displaying unit is used for receiving the operating command of the user to perform the corresponded operation. By means of the technical scheme, full control of the vehicle can be implemented, vehicle and driver assistance and traffic management are performed effectively, abnormality can be detected and found timely, traffic accidents are reduced, and safety of driving and traffic can be improved.

Description

Technical field [0001] The present invention relates to the technical field of vehicle-mounted communication, in particular to a vehicle-mounted communication device and method based on DSRC and Beidou satellites. Background technique [0002] With the rapid increase in the number of motor vehicles in my country, the incidence of traffic accidents has shown a straight upward trend. As traffic accidents not only cause a large number of casualties and bring misfortune to countless families, but also seriously affect economic development and social stability, they have attracted the attention and attention of governments at all levels. Road traffic accidents are a common and frequent social disaster with a high mortality rate, a high rate of disability afterwards, and a large overall loss. Road traffic accidents have become the world's largest public hazard. [0003] Due to the high-speed driving of vehicles, the research on the communication mechanism between vehicles has become a b...

Problems solved by technology

However, these methods have great limitations and cannot meet the requirements of real-time communication between all vehicles

The FM method can only be received by the vehicle, but cannot send information; and the intercom method also has many channel restrictions and cannot be popularized in all vehicles. Therefore, the existing vehicle communication device cannot perform comprehensive control on the vehicle. , thereby reducing driving and traffic safety
