Internet of Vehicles near-field broadcasting method and system based on vehicle-mounted terminal, and vehicle-mounted terminal

Abstract

The invention provides an Internet of Vehicles near-field broadcasting method and system based on a vehicle-mounted terminal, and the vehicle-mounted terminal. The method comprises the following steps: receiving a connection request message sent by a certain device; receiving an information message sent by the device; receiving an end message sent by the device; judging whether the request connection message, receiving the information message and the end message within a preset time period or not; if so, the request connection message, the information message and the end message are sequentially sent to other devices except the device in a device list; and if not, requesting to retransmit the request connection message, the information message and the end message to the device. According to the Internet of Vehicles near-field broadcasting method and system based on the vehicle-mounted terminal, the vehicle-mounted terminal can realize information communication between vehicles in a near-field communication manner under the condition that the Internet of Vehicles cannot be networked, so that the driving safety of the vehicles is improved.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a vehicle-mounted terminal-based near-field broadcasting method and system for the Internet of Vehicles, and a vehicle-mounted terminal. Background technique [0002] With the continuous improvement of people's living standards, the number of cars on the road is increasing. Therefore, vehicle traffic safety becomes one of the problems that people pay close attention to day by day. Among them, the inter-vehicle communication provides information support for the safe driving of the vehicle, and the vehicle web page emerges as the times require. According to the definition of the Internet of Vehicles Industrial Technology Innovation Strategic Alliance, the Internet of Vehicles is based on the intranet, the Internet of Vehicles and the mobile Internet in vehicles. Pedestrians and the Internet, etc.), a large system network for wireless communication and informati...
