基于热释电红外传感器的车流检测装置

Vehicle Flux Detector Based on Pyroelectric Infrared Sensor

介绍了一种车流检测装置的硬件、软件设计和实现过程。该装置采用热释电红外传感器检测是否有车辆通过,由单片机对传感器信号进行计数;单片机同时控制CAN总线控制器进行数据传输。多个车流检测装置组成CAN总线通信系统可实现多车道、多路口的车流统计和监控。实际运行表明该装置安装方便、工作准确、可靠性高。

The hardware,software and carrying out process of the vehicle flux detector are introduced.The detector (uses) the pyroelectric infrared sensor to detect whether there is a passing vehicle,and use microchip to count the signal from the sensor.The microchip controls the CAN BUS controller to transmit the data.A number of the vehicle flux detectors can structrure a CAN BUS communication system to carry out the counting and supervising of many carriages and crossings.The detector can be expediently installed,and has better nicety and releable performance.
