摘要 为实现温室大棚内环境参数监测,提高生产效率,基于RT-Thread嵌入式操作系统和MicroPython编程语言设计了温室环境检测系统。在STM32F4硬件平台上移植了RT-Thread操作系统,使用多种传感器采集环境参数,采集节点将环境数据汇总到网关节点,网关节点通过TCP协议使用NB-IOT模块传输至Onenet物联网平台,实现了温室大棚内温湿度、光照强度、CO2浓度的监测,在PC端和移动设备上查看数据并实现超阈值报警功能。实验表明,系统能够实时显示温室大棚内的环境参数,有助于提高农业数据化水平;MicroPython语言在嵌入式应用开发中具有较强的实用性,能为物联网快速应用提供开发工具。 In order to realize the monitoring of environmental parameters in greenhouses and improve production efficiency,a greenhouse environment detection system was designed based on RT-Thread embedded operating system and MicroPython programming language. The RT-Thread operating system was transplanted on the STM32F4 hardware platform,and various sensors were used to collect environmental parameters. The collection node aggregated the environmental data to the gateway node. The gateway node transmitted data to the Onenet IoT platform through the TCP protocol using the NB-IOT module to achieve the monitoring of temperature,humidity, light intensity and CO2 concentration in greenhouses,workers can view data on the PC side and mobile devices,and realize the super-threshold alarm function. Experiments show that the system can display the environmental parameters in the greenhouse in time,it helps to improve the agricultural datalization level. This application shows that the MicroPython language has strong practicability in embedded application development,and the example provides reference value for the rapid development of IoT applications.
