車輛檢測傳感器可以準確實時獲得各種交通數(shù)據(jù)（包括車流量、車速度、車輛密度、
車頭距、占有率等），是智能交通系統(tǒng)（ITS, intelligent traffic system）中最重要的交通數(shù)據(jù)采集設備之一。本文根據(jù)國內外車輛檢測器技術的發(fā)展，采用微型線圈，并將單片機控制技術和新型的短距離無線接入技術ZigBee 引入車輛傳感器的設計中，從而有效得降低了安裝的工程量，開發(fā)出適用性更強的車輛傳感器。

Abstract: Vehicle detection can collect traffic data (such as vehicle’s flow, speed, density and occupancy ratios). It is one of the key technologies in ITS (intelligent traffic system). In this paper, the design and reality of a new recharge inductive loop vehicle detection sensor with ZigBee technology is presented. This sensor is more feasible with miniature inductive loop, easy maintenance and installation, and intelligent controller.
