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、CO2浓度进行研究和控制。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LCD屏上显示，同时控制加热、制冷、加湿、通风和补光工作，并通过蓝牙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。

Design of Greenhouse Environment Monitoring System Based on Singlechip Microcomputer
Abstract:
China is a large consumer of agricultural products, and agricultural development, as the foundation of the country, plays a key role in ensuring people’s life safety. For the steady and healthy development of agriculture, this paper designed a greenhouse remote environment monitoring system based on the Internet of Things to study and control the main factors affecting greenhouse planting: environmental temperature, soil moisture, light intensity and CO2 concentration. Firstly, the environmental sensor sends the detected environmental parameter information to the data collector. The data collector preprocesses the data and displays it on the LCD screen. At the same time, the data is controlled by heating, cooling, humidification, ventilation and light replenishment. To realize the remote monitoring of greenhouse in LAN, and made a real object, debugging results show that the greenhouse can well realize the monitoring function of greenhouse environment, in line with the design requirements of modern greenhouse system.
Key words:Greenhouse environment; Temperature; Humidity; CO2 measurement and control; Light intensity
