Design of Agricultural IoT in Sunlight Greenhouse Under Conditions of Large Complex System

通过研究日光温室温度多节点大系统的识别采集和处理过程,提出了日光温室复杂大系统智能物联网控制系统的关键技术和存在的问题。针对占用带宽、网络时延特性、丢包率以及功耗等4个方面对物联网承受能力进行了参数数学建模,并运用MCU信号放大系统和信号传感器联合控制日光温室的温度效应,最终发现智能大系统的占用带宽达到35kB,网络时延最高达到20s,丢包率最大为2.5%,证明了智能大系统的物联网特性要比局部小系统控制复杂程度高。

By identifying the acquisition and processing temperature of multi-node system in sunlight greenhouse , it discussed the technology and the existing problems of complex large system of intelligent network control system in the greenhouse. From occupied bandwidth, network delay, the sustainability of parameter mathematical modeling on the Internet of things in four aspects of packet loss rate and the power, and the temperature effect of MCU signal amplification system and signal sensor joint control of greenhouse, finally found the occupied bandwidth intelligent system can reach 35kb, the highest 20s network delay, packet loss maximum rate of 2.5% , proved that the network characteristics of intelligent systems to be higher than the local control system complexity.
