摘　　要：车辆检测现在主要应用到的有红外、地磁、视频和超声波等几种技术,它们各自都具有优缺点。文中分析并设计了一种基于HY-SRF05超声波模块的车辆检测算法:状态机检测算法。该算法能对检测车辆的阀值进行动态的更新,达到准确高效的检测效果。同时,该算法也适用于中、大型停车场的车辆诱导系统和公路上交通车流量的检测。Today, infrared, magnetic, video and ultrasonic are mainly applied to vehicle detections. They each have advantages and disadvantages. This paper analyzes and designs a kind of vehicle detection algorithm that vehicle detection by state machine algorithm base on HY-SRF05 ultrasonic module. The algorithm can detect vehicle threshold dynamic update, to achieve accurate and efficient detection effect. At the same time, the algorithm is also applicable to medium and large vehicles parking guidance system and road traffic vehicle flow detection.
