摘　　要：针对目前停车业对车位充分利用、降低成本、实现无人化智能管理的需求,设计并实现了基于窄带物联网(NB-IoT)的停车监测系统。该系统使用高精度地磁传感器实时获取磁场强度,使用微波传感器作为辅助判断,经过滤波算法处理后判断车位状态,通过NBIoT通信模块上传至服务器存至数据库;通过浏览器访问监测系统可监测实时车位状态,实现对车位使用情况的远程管理。测试结果表明,该设计能够准确检测车位的使用情况,对NB-IoT的应用以及智慧城市建设有一定的借鉴意义。In view of the current parking industry’s demand for fully-utilized parking spaces,cost reduction,and implementation of unmanned intelligent management,a parking monitoring system based on NB-Io T is designed and implemented. The system adopts high-precision geomagnetic sensors to obtain magnetic field strength in real time,uses microwave sensor as an aid in judgment,justifies the status of parking spaces after a filtering algorithm,uploads the parking status to the server through the NB-Io T communication module and stores it in the database. The real-time status of parking space can be monitored by accessing the monitoring system through a browser,and the remote management of the use of parking space can be realized. The test results show that the design can accurately detect the use of parking spaces,which has certain reference significance for the application of NB-Io T and the construction of smart city.
