伴随智能科技的迅猛发展,将自动化控制技术应用于传统温室将成为现代化技术发展的一项新兴的主流趋势,它不仅将自动化控制技术与人们的日常紧密结合在一起,还不断推进自动化控制技术理念的更新和进步。由于我国利用自动化技术的时期有限,在应用于温室环境中,对参数因子控制仍以人工为主,缺乏科学的指导。基于国内现状本文设计了自动化控制网关控制器系统,通过自动化控制系统将温室中的设备通过传感器和无线网络应用起来,实现智能温室系统的远程自动化控制。
本设计采用以三星S3C6410芯片为核心的OKC6410A作为控制中心,以无线传输模块nRF24L01为传输媒介,与底层的数据采集中心的传感器进行交互,进行A/D数据通信,并以TCP/IP协议为传输协议,通过网络通信的方式与客户端管理中心进行数据交互,实现了自动控制系统网关控制器的设计。该网关采用S3C6410板载的Linux系统作为嵌入式控制系统,连接互联网,与连接到网关服务器的客户端进行网络数据通信。客户端管理中心可以通过网络向网关控制器发送控制指令,从而得到底层采集到的数据,并控制网关驱动一些外围设备,以达到远程操作智能温室内环境参数因子的目的。
通过自动化控制技术,搭建模拟温室环境测试平台,根据测试方案对本系统进行测试,结果表明数据采集终端将温湿度等数据通过无线通信网络准确传输给服务器端,服务器端对数据参数进行分析与存储,然后通过CGI接口传给PC机Web客户端,操作员可以通过终端网页对环境因子分析,实现自动化远程控制温室内相关设施,验证该方案的正确性和可行性。

论文外文摘要: |
With the rapid development of smart technology, applying the automatic control technology to conventional greenhouse will become a trend . The tech will not only combine automatic control technology and people's daily work closely , but also open up automation and control technology idea continuing to update and progress. Due to the limited date of automation technology, the parameters are still controlled manifestation , lacking of the scientific guidance. Based on the present situation in this paper an intelligent greenhouse control system is designed ,the system connected conventional greenhouse equipment through sensors and wireless networks to realize the remote automatic control system of intelligent greenhouse.
The design uses the S3C6410 processor whose core is Samsung S3C6410A chip as the control center, which it communicates with the underlying data collecting center via the wireless module nRF24L01. In addition, based on TCP/IP protocol, it does data interaction with the client management center by means of network communication and implements the design of gateway controller of automatic control system for vegetable greenhouses. The gateway controller uses the S3C6410 on board Linux system as the embedded controlling system and it can communicate with the client connecting to the gateway server through the access to Internet. The client management center can send control commands to the gateway controllers through the network, then getting the data collected by the underlying, and controls the gateway driving some peripheral devices, in order to achieve the purpose of remote operating the vegetable greenhouse environment.
Through automation and control technology, building a platform simulating greenhouse environment,and testing the system according to the testing plan, the results indicate that data collection terminals accurately transmitted data, such as temperature and humidity to the server through wireless network,server analyzed and saved data, then passed those to the PC interface via CGI web client.Managers can also analyze environmental factors through page and remotely control corresponding devices in greenhouse. Achieving internal automation control for remote greenhouse-related facilities, which the correctness and feasibility of the project can be verified.
