基于压电和线圈的交通参数检测系统设计

Design of traffic data detection system based on piezoelectric and loop sensors

根据ITS对交通参数采集的需求,提出一种交通参数检测系统的设计方案。详细介绍了利用环形线圈和压电传感器进行交通参数采集的原理和计算方法。设计了用DSP和单片机实现的交通参数采集系统。该系统可以同时实现车型分类和动态称重。

Given the Intelligent Transportation System demand, this paper proposes a design method for traffic data detection. It presents the principle and calculating method based on loop and piezoelectric sensors. The detection system is designed with DSP and MCU. It has the function of weigh-in-motion （WIM） and Automatic Vehicle Classification （AVC） systems.
