The invention belongs to the technical field of intelligent traffic, and discloses a road traffic state information intelligent acquisition device, which is characterized in that a road condition acquisition module acquires road condition information of a traffic road in real time; the wireless transmission module sends the collected road condition information of different traffic roads to the data conversion module through a mobile communication public network; the data conversion module is used for converting the acquired traffic road condition information picture into a 4-20mA current signal by using the data conversion module; the data processing module is used for filtering the traffic road condition information picture from the data conversion module; and the centralized control center sends the global traffic road condition information to the target vehicle through the mobile communication public network, and the target vehicle selects the target road condition information according to the global road condition information. According to the invention, the vehicle can receive the road condition information richer than the local road condition information, so that the overall condition of the current road can be known more comprehensively, the updating efficiency is high, and the real-time performance is good.

    本发明属于智能交通技术领域,公开了一道路交通状态信息智能采集装置,路况采集模块对交通道路路况信息进行实时采集;无线传输模块将采集的不同交通道路路况信息通过移动通信公网发送到数据转换模块;数据转换模块用于将采集的交通道路路况信息画面利用数据转换模块转换成4‑20mA的电流信号;数据处理模块,对来自数据转换模块的交通道路路况信息画面进行滤波处理;集控中心通过移动通信公网向目标车辆发送全局交通路况信息,由目标车辆根据全局路况信息选取目标道路路况信息。本发明可以使车辆可以接收到比局部路况信息更加丰富的路况信息,以更加全面地了解当前道路整体的状况,且更新效率高,具有较好的实时性。
