摘　　要：为了采集城市道路固定断面的交通数据,基于各向异性磁阻传感器HMC5983设计了一种交通数据采集设备。对比分析了PNI电感式地磁传感器和Honeywell各向异性磁阻传感器的性能特点,选择了性能更优的三轴磁阻传感器HMC5983。重点介绍了交通数据采集器电路和软件设计。实装测试结果表明,交通数据采集器检测精度较高,基本满足实际应用需求。In order to acquire the traffic data of the fixed section of the urban road,a traffic data acquisition device is designedbased on the anisotropic magnetoresistive sensor HMC5983. The performance characteristics of PNI inductive geomagnetic sensorand honeywell anisotropic magnetoresistive sensor are compared and analyzed. The three-axis magnetoresistive sensor HMC5983 with better performance is selected. The design of traffic data acquisition device circuit and software are introduced emphatically.The actual installation test results show that the detection accuracy of the traffic data acquisition device is high,which basicallymeets the actual application requirements.
