摘要
为了更进一步提高无线环境监测系统的性能,以NB-IoT传输技术和传感器技术为核心技术,设计出广覆盖、低功耗的环境监测系统。该系统以STM32F103C8T6嵌入式芯片为主控制器;感知层通过传感器采集温湿度及甲醛、粉尘、TVOC含量等环境数据;传输层使用中移物联M5310A模块将感知层数据输出到平台层(OneNET云平台);应用层使用手机APP实时观看监测数据。优化系统软硬件后,环境监测系统能够稳定运行,实时准确采集和上传相关环境数据,方便用户远程监测,为环境监测提供有力保障。
In order to improve the performance of wireless environmental monitoring system,an environmental monitoring system with wide coverage and low power consumption is designed based on NB-IoT transmission technology and sensor technology.The main controller of the system is STM32F103C8T6 embedded chip.Firstly,the sensing layer collects environmental data such as temperature and humidity,formaldehyde,dust,TVOC and so on through sensors.Then the transport layer uses the module of M5310A to output data from perception layer to platform layer(OneNET cloud platform).Finally,the application layer uses mobile APP to watch monitoring data in real time.By optimizing the hardware and software of the system,the environmental monitoring system can run steadily and upload the environmental of real time data.It is convenient for users to monitor and control remotely and provides a strong guarantee for environmental monitoring.
