Inter-vehicle information transmission method based on Bluetooth communication

Abstract

The invention discloses an inter-vehicle information transmission method based on Bluetooth communication. The method comprises the following steps: S1: inputting a trigger signal through a first terminal device; S2: extracting licence plate information of a preceding vehicle through the first terminal device; S3: broadcasting Bluetooth handshake information through a first Bluetooth module in thefirst terminal device, wherein the Bluetooth handshake information comprises the licence plate information of the preceding vehicle extracted in step S2 and a control instruction sent by the first terminal device; and S4: judging, by a second Bluetooth module, whether the received Bluetooth handshake information matches the own license plate information, and if so, transmitting the control instruction to a second terminal device to execute a corresponding control action. The inter-vehicle information transmission method has the following effects: the demand that a subsequent vehicle activelysend a prompt message to a preceding vehicle after traveling at a close distance can be met, in the case that the preceding vehicle cannot be directly prompted by the existing light and whistle, the control instruction can be directionally transmitted through a short-distance Bluetooth connection, thus provide a more convenient driving environment for drivers.

Description

technical field [0001] The invention relates to the Internet of Vehicles technology, in particular to a method for transmitting workshop information based on Bluetooth communication. Background technique [0002] With the development of the economy, the number of people using cars is gradually increasing, and the frequency of traffic accidents is also increasing. In the prior art, the information exchange between vehicles is mostly realized through lights and whistles, but the driving level of the drivers is uneven, and some drivers still have some bad driving habits, often ignoring the situation of the rear vehicles. Therefore, the conventional It is difficult to meet the driver's information transmission needs in the existing road traffic driving process. [0003] With the development of Internet of Vehicles technology, some people have proposed to use special communication equipment to realize mutual interaction between vehicles, but its hardware configuration is relativ...
