The invention discloses a traffic early warning system based on the Internet of Vehicles. The system comprises a traffic controller used for controlling traffic lights and a road side unit connected with the traffic controller. The road side unit is used for reading state information of the traffic controller after establishing network connection with a vehicle end to be pre-warned; querying a corresponding early warning signal in a preset early warning response table according to the state information, and sending the early warning signal to the vehicle end; and the vehicle end is used for outputting an early warning prompt according to the early warning signal. The state information of the traffic controller is obtained through the road side unit, and the corresponding early warning signal is fed back to the vehicle end, so that the vehicle end outputs an early warning prompt to a driver, the traffic early warning signal is timely and accurately provided for the driver, and the traffic safety is guaranteed.
本发明公开了一种基于车联网的交通预警系统,所述系统包括用于控制交通信号灯的交通控制器,以及与所述交通控制器连接的路侧单元;所述路侧单元用于与待预警的车端建立网络连接后,读取所述交通控制器的状态信息;根据所述状态信息在预设的预警响应表中查询对应的预警信号,发送所述预警信号给所述车端;所述车端用于根据所述预警信号输出预警提示。通过路侧单元获取交通控制器的状态信息,反馈对应的预警信号给车端,以使车端输出预警提示给驾驶员,及时准确地向驾驶员提供交通预警信号,保障交通安全。
