The invention relates to the technical field of data communication, and provides an efficient data communication method of a highway electromechanical system, which comprises the following steps: collecting the number of running vehicles, the speed of the vehicles and the distance between adjacent vehicles; determining the vehicle speed stability of the target vehicle, marking an abnormal vehicle, and determining the traffic condition complexity; the risk radar velocimeters at each acquisition moment and the risk radar velocimeter group at the same acquisition moment are marked, the moment importance of the acquisition moments is determined, all the acquisition moments are divided into different time periods, and the focus attention of the time periods, the risk time periods and the normal time periods are determined; and according to the traffic condition complexity of the radar velocimeter at all acquisition moments of the normal time period and the focus attention of the radar velocimeter at the normal time period, respectively transmitting and communicating data acquired by the radar velocimeter at the risk time period and the normal time period. The objective of the invention is to solve the problem that the compression efficiency and the data precision cannot be balanced in expressway electromechanical data transmission.

    本发明涉及数据通信技术领域,提出了一种高速公路机电系统的高效数据通信方法,包括:采集正在行驶的车辆的数量、车辆的速度和相邻车辆的车距;确定目标车辆的车速稳定性并标记异常车辆,确定交通状况复杂度;标记每一采集时刻的风险雷达测速仪和同一采集时刻的风险雷达测速仪组,确定采集时刻的时刻重要性,将所有采集时刻划分至不同时间段,确定时间段的重点关注度、风险时间段和正常时间段;根据雷达测速仪在正常时间段的所有采集时刻的交通状况复杂度和正常时间段的重点关注度,分别对雷达测速仪在风险时间段和正常时间段采集的数据进行传输和通信。本发明旨在解决高速公路机电数据传输无法平衡压缩效率和数据精度的问题。
