【摘要】 随着现代温室朝着集约化、规模化方向的发展和温室管理智能化要求的提高，温室测控系统实现远程通信，进而实现温室内生产与管理的一体化，是现代智能温室发展的必然趋势；现代传感器技术、通信技术、自动化技术和计算机技术的发展，又为这一发展趋势推波助澜，本文就这一研究热点，集中对温室数据采集系统远程通信接口进行了设计探讨。 第1章，详细论述了集散控制系统(DCS，Distributed Control System)、现场总线控制系统(FCS，Field control System)在温室测控领域的应用情况，分析了各自的利弊。同时借鉴以太网在工业领域中的研究进展，探讨了基于以太网温室测控系统的应用前景，进而提出了本论文的研究任务。 第2章，对温室数据采集系统远程通信接口的多种设计方案进行了比较，详细论述8位微控制器驱动以太网控制芯片作为温室数据采集系统远程通信接口的硬件设计方案，以达到与上层信息网络实现互联的目的。 第3章，详细论述了以太网控制芯片驱动程序的设计，同时将TCP／IP网络协议作为一种嵌入式应用，并根据单片机系统的实际资源限制，对该协议进行了裁剪。分析了该系统存在问题，提出了一种协议改装的解决方案。 第4章，采用Java网络编程语言，实现基于Web的远程监测平台，取代了传统集散控制系统中的上位机软件，同时为真正消除底层控制网络孤立于上层信息网络不利现象，实现两者的无缝集成作了初步设计。 第5章，为方便在远程通信程接口开发过程中的调试、检测，本文采用虚拟仪器技术，以Labview为软件开发平台，设计了一个温室数据采集系统仿真，大大加快了系统调试、开发任务。 第6章，对全文进行系统的总结，并对该接口的研究应用进行展望。更多还原

【Abstract】 With the intensive and scale development of modern greenhouses and the advancement of their intelligent management, present-day greenhouse technology is witnessing a trend of integration of greenhouse production and its management through remote communication. The development of modern sensor technology, communication technology, automation technique and computer technique add fuel to the fire for this trend. The remote communication interface for greenhouse data acquisition system is designed and discussed in this paper as the research focus.The first chapter discusses the application of Distributed Control System and Field Control System in the field of greenhouse monitoring and control, and analyzes their respective advantages and disadvantages. In light of latest progresses in Ethernet technology in industrial sector, the paper has set up as its goal the study of greenhouse monitoring and controlling system based on the application of Ethernet technology.In the second chapter, Many designs of the remote communication interface for greenhouse data acquisition system is compared, and a hardware design by integrating an ordinary 8 bit MCU and a Ethernet controller chip is described in detail, for the purpose of connecting the top networking of information.In the third chapter, the design of Ethernet control chip driver is discussed and TCP/IP protocols are tailored as an embedded application in view of the limited resource of MCU system. Problems with this system is also analyzed, a solution with refitting protocols is proposed as well.In the fourth chapter, a remote monitor platform based on web is implemented by Java network programing language, which replaces the host computer software in traditional Distributed Control System and avoids the isolation of bottom control networking from top information networking. A preliminary design for such seamless integration is also discussed..In the fifth chapter, a simulation on greenhouse data acquisition system is designed with Labview platform as a virtual instrument technique to the advantage of efficient debugging and examination in the development process of remote communication interface, which significantly quickens the debugging and development of the system.The last chapter summarizes the paper, and discusses the application prospect of this interface.更多还原
