摘　　要：设计了一种基于巨磁阻(GMR)传感器的Zig Bee车辆检测系统,利用高灵敏度的GMR传感器采集道路上经过车辆对地磁场的扰动信号,然后通过检测节点对采集的数据进行打包处理,并通过Zig Bee无线网络系统将数据传输给上位机。实验表明:该系统检测工作稳定可靠,且节点尺寸小,无需布线,易于安装。A Zig Bee wireless vehicle detecting system based on giant magneto-resistance （GMR） sensor is designed, where GMR sensor is used to detect the disturbances signal of geomagnetic field generated by the passing vehicle on the road. The collected data is then packeting processed by detecting node and transmitted to the host computer through Zig Bee wireless network system. Experimental results indicate that the system is stable and reliable, and the node is small, needless to layout wires and easy to be installed.
