温室天窗集中控制系统的设计

The Design of Centralized Control System for Skylight of Greenhouse

鉴于目前我国对于温室天窗的操作大多采用人工控制或分散的自动控制,设计了一种能够对多个温室天窗实现远距离集中控制的控制系统,并详细介绍了该系统的软硬件设计方法。系统的集中控制中心设置在中控室,采用计算机即可全面控制;系统采用AT89C2051单片机作为控制核心,利用Zigbee模块组建无线局域网,实现温室群远程数据采集及开关控制。试验表明,该系统可以良好地完成开启和关闭天窗作业,自动化程度高,控制方便,满足农户对温室环境参数有效监测管理的需求。

Because most of greenhouses＇ skylights in our country are using manual or distributed automatic control currently,here designs a control system which can finish remote control of many skylights of different greenhouses,and introduces the details of the system＇s hardware and software.The control center of this system is a computer set in Central control room;It uses AT89C2051 as the controller and sets up wireless LAN module by Zigbee for data acquisition and switch control.Tests show that the system can complete opening and closing skylights well,and easy to control with high degree of automation.It can meet the farmers＇ needs for effective monitoring and management of greenhouse environmental parameters.
