温室环境监控系统设计

Design of Greenhouse Environment Monitoring System

针对我国北方冬季存在的大量冷棚(塑料温室大棚)安全性和智能性差,其塑料幕布容易出现意外破损,不能及时被人发现,且温室智能性不足等问题,设计出一套智能型设备,用于提高冷棚的安全性和智能性。本系统除了对温室内温度、湿度、光照等环境变量进行检测控制外,还考虑到在我国北方寒冷大风等恶劣气候下,冷棚幕布容易发生破损,故而对温室的幕布破损情况进行检测。系统采用S3C2440作为主控芯片,在mini2440开发板上,进行接收并解析传感层采集的温室环境数据,进而控制执行器设备动作,保持温室环境稳定。加之LCD来实现温室环境的现场人机交互功能,用ONENET云平台实现温室环境远程监控。

In view of the poor safety and intelligence of a large number of cold greenhouses(plastic greenhouses)in northern China in winter,the plastic curtain is prone to accidental damage,can not be found in time,and the lack of intelligence of greenhouses,a set of intelligent equipment is designed to improve the safety and intelligence of cold greenhouses.In addition to the detection and control of indoor temperature,humidity,light and other environmental variables,the system also takes into account that the curtain of the cold shed is easy to be damaged in the cold and windy weather in northern China,so it detects the damage of the curtain of the greenhouse.The system uses S3 C2440 as the main control chip.On the mini2440 development board,it receives and analyzes the greenhouse environment data collected by the sensor layer,and then controls the action of the actuator equipment to keep the greenhouse environment stable.In addition,LCD is used to realize the on-site human-computer interaction function of greenhouse environment,and ONENET cloud platform is used to realize the remote monitoring of greenhouse environment.
