基于ZigBee的车量数据采集器的研究

Research of traffic data collection system based on ZigBee wireless technique

针对现有机动车性能检测仪器的不足,利用各向异性磁阻传感器和ZigBee技术,设计了一款无线交通量数据采集器,并对该传感器节点的硬件结构和软件设计分别作了详细介绍。该传感器将所采集到的交通量数据通过ZigBee无线网络发送至上位机,由上位机对相关信息进行处理,实现对车辆进行分类的功能。

To solve the problems of existing motor vehicle detector, a wireless vehicle detector using the anisotropic magnetoresistive sensor and ZigBee is designed. The paper introduces the basic principle of the sensor, including the hardware and the software structure. The detector collects information about the traffic data, and sends the information to the upper computer. Then, the upper computer could deal with it in order to classify the vehicles.
