Abstract

The invention discloses a method for transmitting the data of Internet of Vehicles. The method comprises the steps of obtaining the operating data of vehicles, compressing the operating data into data messages and saving the data messages in a transmission cache region, when detecting that a vehicle goes into the acquisition range of a preset data acquisition point, setting the preset data acquisition point as a specified data acquisition point, and controlling a short-distance wireless communication module to extract the data messages from the transmission cache region and send the data messages to the preset data acquisition point. The invention also discloses a device for transmitting the data of the Internet of Vehicles. The method is capable of reducing the cost of the data transmission of the Internet of Vehicles.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device for the Internet of Vehicles. Background technique [0002] At present, the basic goal of the development of the Internet of Vehicles is to realize the extraction and effective use of the operating data of all vehicles, and to effectively monitor the operating status of all vehicles according to different functional requirements and provide a wireless network with comprehensive services. In the prior art, the data transmission of the Internet of Vehicles is based on mobile communication networks, such as 2G, 3G and 4G networks. As we all know, the data traffic cost of the mobile communication network is high, while the data traffic of the Internet of Vehicles is huge, which leads to a high cost of data transmission of the Internet of Vehicles. [0003] The above content is only used to assist in understanding the technical sol...
