A method for pushing alarm information based on vehicle-to-vehicle communication

Abstract

The invention relates to a method for pushing alarm information based on vehicle-to-vehicle communication. A method for pushing alarm information based on vehicle-to-vehicle communication, comprising a first vehicle-mounted terminal and a second vehicle-mounted terminal, according to the following steps: the first vehicle-mounted terminal opens the Direct function; the thread behind the platform searches for nearby Direct devices in sequence every two seconds; The data is sent to each searched second vehicle-mounted terminal to apply for a point-to-point direct connection; the data vector △X1 in the stored data frame, the second vehicle-mounted terminal obtains the coordinates Xa2 (Ja2, Wa2) of the first GPS positioning information, after 2s Obtain the coordinates Xb2 (Jb2, Wb2) of the second GPS positioning information; after the connection is completed, the first vehicle-mounted terminal will enable the server service in the background thread, that is, send a voice warning message to the second vehicle-mounted terminal. This method is more intelligent and convenient when used.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a method for pushing alarm information based on vehicle-to-vehicle communication. Background technique [0002] When a vehicle is driving to an intersection without traffic lights, especially at a high speed on a road section with a small traffic flow, traffic accidents will often occur. Now the vehicle-mounted terminal is widely used in vehicle driving, and it is completely possible to realize the vehicle through the vehicle-mounted terminal. Vehicle communication and early warning. However, when the vehicle is running, the driver does not have enough time to set and respond to the vehicle-to-vehicle communication in detail on the vehicle-mounted terminal. Therefore, a warning information push method based on vehicle-to-vehicle communication can be used to achieve the role of safety warning. [0003] If the existing vehicle-to-vehicle communication is used Th...

Problems solved by technology

[0003] If the existing vehicle-to-vehicle communication is used The connection method is to be in the In the hotspot coverage environment, you can only connect by entering the password. This method can be used without It cannot be connected in a covered environment, and the connection requires complicated settings and verification processes, which is not convenient for vehicle-to-vehicle communication during driving

current Although the Direct technology can realize point-to-point direct connection, it does not need Hotspots, but still have to complete the connection before transmitting various data information, so there is a problem, that is, the receiver must first confirm the connection, and then obtain the applicant's retransmission message to know the applicant's intention, then the applicant sends The connection intention may not be useful to the receiver, which will lead to unclear purpose and confusing information push
