Research And Design Of Intelligent Greenhouse Remote Monitor System

With the growing tension of per capita arable land resource, facility Agriculture as a sustainable development of agric ulture's important way has been receiving increasing attention around the world. Modern greenhouse is the essence of facility agriculture, so various new techniques have been utilized in Smart Greenhouse Control System and show wide development prospects.This paper bases on a lot of greenhouse control papers, aiming at the current domestic the requirement of large scale greenhouse long-range management, and traditional "bus line" communication defects, applies embedded long-range monitoring technical and wireless communication technology in design and the research of intelligent greenhouse control system.This system is adopted in the hardware structure of the Client/Server mode, the Client by multiple field control system. Client takes microcontroller as the core, the modularized structure design, though wireless network realization environmental data acquisition of greenhouse and implementation of equipment of wireless radio control. That structure enables the user make up system with required convenient and flexible. This system is flexibility. The range of application is wide. The capability of on-site response is strong. Server takes 32 bit ARM micro processor S3C2440 as core, combines wireless communication modular to realize.This server system based on embedded Linux operating system, using the embedded Boa server and CGI dynamic network techniques to realize the remote monitoring of greenhouse environment. According to the characteristics of the star type wireless network, formulate the corresponding wireless communication program. In view of the greenhouse environment, comprehensive analysis and neural networks and fuzzy control their respective advantages and disadvantages, and then develop new control algorithm model, with fuzzy compensation decoupling control algorithm, and realize the greenhouse intelligent control. According to the requirement of intelligent controller algorithm developed intelligent greenhouse on-site control program, and coordinated development computer debug software ,which is used for greenhouse on-site controlling effect real-time monitoring, as well as the control scheme's formulation and revision.In the intelligent greenhouse environment, tested the real-time ability for the system's wireless data acquisition and device control, established the remote monitoring schemes in the environment of network, and tested the device control module's ability to drive large equipment by the corresponding electric circuit. This system has a good real-time, high universality, stated intelligent and modularization, so that it accords to the situation of our country.
