The invention discloses a traffic information data collection system and method based on an ARM processor. The data collection system comprises an upper computer module, an interface module, an ARM processor module, a CAN transceiver module and a data collection module. The upper computer is used for configuring radar state parameters, sending processing information and receiving and storing collected data. The interface module is used for communication and data transceiving between the upper computer and the ARM processor module; and the ARM processor module completes data receiving, transmission and processing. The method comprises the following steps: performing pipeline processing on radar data transmitted through a CAN bus protocol by adopting a multi-thread concurrent model and a double-buffer processing mode, and finally transmitting a processed data result back to a data background through a network cable for comprehensive processing. According to the invention, a driving program based on an ARM core processor is designed autonomously, and the original position, speed, signal intensity and other information of a traffic target are collected efficiently and quickly by usinga CAN bus protocol.

    本发明公开了一种基于ARM处理器的交通信息数据采集系统及方法,数据采集系统包括上位机模块、接口模块、ARM处理器模块、CAN收发模块和数据采集模块;上位机用于配置雷达状态参数、发送处理消息、接收及存储采集到的数据;接口模块用于上位机和ARM处理器模块之间进行通信与收发数据;ARM处理器模块完成数据接收、传输和处理。方法包括:采用多线程并发模型、双缓冲区处理模式,对通过CAN总线协议传输的雷达数据进行流水处理,最终将处理过的数据结果通过网线回传至数据后台进行综合处理。本发明自主设计基于ARM内核处理器的驱动程序,利用CAN总线协议,高效、快速的采集交通目标原始的位置,速度和信号强度等信息。
