The invention is suitable for the technical field of the Internet of Vehicles, and particularly relates to a data interaction method and system based on the Internet of Vehicles, and the method comprises the steps: constructing a wireless positioning base station group and an intersection road map; acquiring wireless monitoring signal data from the wireless positioning base station group, and performing time-sharing interception on the wireless monitoring signal data to obtain time-sharing monitoring signal data; performing signal extraction on the time-sharing monitoring signal data, calculating the distance between the positioning base station and each wireless communication device, and constructing a communication positioning map; and determining the number of vehicles in each lane based on the communication positioning map, generating a traffic signal lamp control instruction based on the intersection road map, and sending the traffic signal lamp control instruction to the traffic signal lamp. According to the invention, the positions of the vehicles are automatically determined to indirectly identify the number of the vehicles in each lane, the priority of release of each lane can be determined based on the number of the vehicles in the lane, active correction of the passing time according to the conditions of the vehicles in the lane is realized, and the passing efficiency is greatly improved.
本发明适用于车联网技术领域,尤其涉及一种基于车联网的数据交互方法及系统,所述方法包括:构建无线定位基站群和路口道路地图;从无线定位基站群获取无线监控信号数据,对无线监控信号数据进行分时截取,得到分时监控信号数据;对分时监控信号数据进行信号提取,计算定位基站与各个无线通讯设备之间的距离,构建通讯定位地图;基于通讯定位地图确定各个车道内车辆的数量,基于路口道路地图生成交通信号灯控制指令,并发送至交通信号灯。本发明自动确定车辆的位置,以间接识别车辆在各个车道内的数量,基于车道内车辆的数量,可以确定各个车道放行的优先级,实现了根据车道内车辆状况进行通行时间的主动修正,大幅提升了通行效率。
