| 摘 要： | 车辆超速等交通违规行为的抓拍要求对车速进行精确检测，传统线圈检测器存在测速精度不高等缺点。该文设计一种用于车辆测速的交通数据采集系统，以CPLD为控制核心，通过设计相关的数据采集电路，实现对车辆交通数据的采集。通过CH365接口芯片，将数据实时地传到计算机中进行分析处理，并输出不同信号，满足不同检测需求。实验表明，该系统设计合理，能较好地用于车辆测速等交通检测系统中。

| Abstract: | Snapping traffic rule-breaking behavior such as vehicle over-speed requires detecting vehicle's speed accurately.There are some problems with the conventional loop detector,which can't detect vehicle's speed exactly.A kind of traffic data collection system which is used for detecting vehicle's speed is designed.This system is mainly controlled by CPLD.It collects the data of vechicles by designing the correlative electrocircuit.The collected data is transmitted to the computer real-timely by the device of C... |
