摘要
车辆检测器担负着为智能交通系统(ITS)采集数据的任务,具有重要的研究意义。环形线圈车辆检测器具有性能稳定,性价比高,适应性强等优点,市场应用最为广泛。但目前的环形线圈车辆检测器存在误检率较高,且不能对检测数据进行存储。针对上述问题,设计了基于DSP的环形线圈车辆检测器,实验结果证明设计不仅稳定有效,而且降低了误检率。
A vehicle detector plays an important role in collecting traffic data for an intelligent traffic system （ITS）. The loop vehicle detector is widely used owing to its advantages of high performance-price ratio, good adaptability and stability. This paper presents the improved design of a loop vehicle detector based on DSP,which can remedy the limitations of current detectors on the market that there areno storage devices available for detected data and that the detection error rate is high. The experimental results show that the improved design is not only stable in performance, but also effective in reducing the detec- tion error rate.
