A roadside parking monitoring system based on wireless sensor networks

为了构建基于无线传感器网络的大规模、低成本、低功耗的城市路边停车检测系统,本文提出了一种停车检测传感器节点硬件及软件设计方案。该系统硬件部分利用磁阻传感器实现车辆磁信号检测,软件部分主要实现基于磁信号的车辆检测算法。实地部署了80多个传感器节点的路边停车检测系统,实际应用表明该系统车辆检测精度高,达到了设计要求。

In order to build wireless sensor network-based large-scale, low-cost, low-power roadside parking monitoring system, this paper proposed the hardware and software design for parking vehicle detection sensor node. The hardware of the system is using the magneto resistive sensor for the vehicle magnetic signal detection, the software implements the vehicle detection algorithm based on magnetic signal. More than 80 sensor nodes are deployed on the roadside parking spaces, practical application shows that the system has high accuracy rate of vehicles detection.
