针对停车场车位信息流通不顺畅,停车位供不应求的问题,以MSP430微控制器为核心,设计了基于LoRa的智慧停车管理系统。系统由采集节点、网关、云服务器和客户端组成。地磁传感器检测停车位的状态,并利用RFID射频识别技术识别车辆信息,并通过LoRa实时将车位状态及车辆信息发送给网关,同时网关GPRS模块将数据上传到云端并进行分析处理,网页端实现停车信息的动态管理。测试结果表明,设计的系统降低了停车场空置率,可以实现线下停车场资源共享。

Aiming at the problem of poor parking information circulation in parking lots,which leads to the shortage of parking spaces,a intelligent parking management system based on LoRa is designed with MSP430 microcontroller as the core.The system consists of acquisition node,gateway,cloud server and client.Firstly,the geomagnetic sensor detects the parking status,and identifies the vehicle information using RFID technology.Then,the parking status and vehicle information are sent to the gateway through LoRa in real time.At the same time,the data are uploaded to the cloud by GPRS module of the gateway and processed.Finally,the dynamic management of parking information is realized on the web page.The test results show that the designed system reduces the vacancy rate of the parking lot and realizes the resource sharing of the off-line parking lot.
