摘 要
我国是农产品消费大国,农业发展作为国之根基,对保障国民的生命安全起到关键作用,为了农业稳步健康发展,本文设计了基于物联网的大棚远程环境监测系统,针对大棚环境种植影响的主要因素:环境温度、土壤湿度、光照强度、土壤肥力等进行研究和控制。首先环境传感器将检测到的环境参数信息发送给数据采集器,数据采集器对数据进行预处理并在OLED屏上显示,同时控制加热、制冷、灌溉、补光、施肥等工作,并通过WiFi模块发送到无线传感网中,从而可实现温室大棚内多监测点同时监测,实现温室大棚在局域网内的远程监测,并制作了实物,调试结果显示,该温室大棚能够很好的实现对温室环境的监测功能,符合现代温室大棚系统的设计需求。

Abstract:
China is a big consumer of agricultural products, and agricultural development, as the foundation of the country, plays a key role in ensuring the safety of people’s lives. For the steady and healthy development of agriculture, this paper designed a greenhouse remote environmental monitoring system based on the Internet of Things to study and control the main factors affecting the greenhouse environment planting: environmental temperature, soil moisture, light intensity, soil fertility, etc. First of all, the environmental sensor sends the detected environmental parameter information to the data collector, the data collector preprocesses the data and displays it on the OLED screen, while controlling the heating, cooling, irrigation, filling light, fertilization and other work, and sends it to the wireless sensor network through the WiFi module, so as to realize the simultaneous monitoring of multiple monitoring points in the greenhouse. The remote monitoring of greenhouse in local area network is realized, and the real object is made. The debugging results show that the greenhouse can realize the monitoring function of greenhouse environment well, and meet the design requirements of modern greenhouse system.
