摘要
为了满足云端智能集装箱房管理平台在线实时跟踪定位需求,采用了低功耗物联网新技术NB-IoT作为数据传输网络。以主控芯片STM32L151、集成NB-IoT和GNSS功能的BC20模组、温湿度传感器DHT11为硬件系统架构,设计GPS终端主控软件和云服务器端监控软件,给出了主要AT指令串口程序,特别介绍了阿里云ECS服务器及百度地图的嵌入方法。测试结果表明,监控软件平台能够实时定位集装箱房以及显示温湿度检测曲线。该系统成本低、功耗低、免维护、使用寿命延长、与云平台兼容且预留接口兼容各种物联网传感器,对于各类基于NB-IoT的物联网系统设计具有一定的参考价值。
In order to meet the demand of real-time tracking and positioning of container house from smart cloud monitoring system.NBIoT is adopted as the data transmission network.The hardware system is composed of STM32L151,BC20 module integrated with NBIoT and GNSS and temperature&humidity sensor DHT11.The software design includes GPS terminal control program and cloud monitoring program and gives some AT instruction UART code.In addition,Alibaba cloud ECS and the embedded design of Baidu map are introduced.The results indicate that the cloud monitoring platform can track and position container house and can display temperature&humidity curve in real time.This GPS is low-cost,low-power,maintenance-free with long service life,compatible with cloud platform and reserves some ports for sensors.It gives reference to some other kinds of NB-IoT applications.
