    目的 以NB-IoT低速率窄带宽物联网技术为核心,研制一套以5G低功耗海量连接场景前期技术为基础的智能温室环境自动调控系统。方法 应用MSP430F149超低功耗芯片采集环境信息,依托NB-IoT蜂窝物联网平台,云端智能调控系统,结合多传感器融合与模糊PID-分级控制技术, 根据用户需求调节温室环境。结果 该系统在温室大棚内实地应用的结果表明:温室环境信息采集相对误差不超1%,平均控制精度在3.57%(±1.0 ℃),无传输距离限制,实现作物生长温度的自动调节。结论 该系统稳定可靠,为作物的生长提供良好环境,对作物的研究提供有力的技术支撑。

    Abstract:

    Objective To develop an automated greenhouse environmental monitoring and control system based on an NB-IoT low-rate narrow bandwidth networking and 5G low-power massive connection technology.Method Ultra-low power chip MSP430F149 was applied to collect environmental information. Using the NB-IoT's cellular networking platform and the cloud intelligent control system and combining multi-sensor fusion with fuzzy PID-grading control technology, greenhouse environment was controlled according to user needs.Result Using the automated system in greenhouse, the relative error of greenhouse environmental information collection was below 1%, the average control accuracy was 3.57% (±1.0 ℃), the transmission distance was not limited and the automatic regulation of crop growth temperature was realized.Conclusion The system is stable and reliable, and provides a favorable environment for plant growth as well as a strong technical support for crop research.
