基于LoRa和Nb-IoT的智慧路边无人值守停车云系统

对目前路边停车场需要人工值守的缺点,提出一种采用地磁、地锁、LoRa和NB-IoT多种技术结合的无人值守云系统。全面阐述了系统方案,设备选型,系统框架,通讯方案,难点功能等内容。采用LoRa和NB-IoT相结合的通讯方案解决了类似系统单独用一种通讯方案时存在信号不畅、功耗较高和通讯费用高的问题。基于地磁和地锁的创新设计,用智能算法判断车辆驶入状态,可靠性强,无需人员值守。系统目前已经投入使用,效果良好,对类似系统的建设有借鉴作用。

Intelligent Roadside Unattended Parking Cloud System Based on LoRa and Nb-IoT

In view of the shortcomings of the current roadside parking, an unmanned cloud system using geomagnetic, ground lock, LoRa and NB-IoT technologies is proposed. The system scheme, equipment selection, system framework, communication scheme, and difficult functions of this system are described. The communication scheme combining LoRa and NB-IoT solves the problems of poor signal, high power consumption and high communication cost when similar systems use a single communication scheme. Based on the innovative design of geomagnetism and locks, an intelligent algorithm is used to judge the driving status of vehicles, which is reliable and does not require personnel on duty. And it has been put into use with good results. It can be used as reference for similar systems.
