Abstract: in view of the traditional manual time-consuming and wired monitoring complex wiring,2013 security cameras with dvr, maintenance limitations difficult,2014 asus wireless monitor, sensor and ZigBee wireless network technology, puts forward the design scheme of Intelligent Greenhouse Monitoring System of wireless sensor networks. This system uses ZigBee technology to realize wireless transceiver to collect data and information, data and control information is transmitted to the Internet through the common gateway interface CGI. The operator can from a distance of
system consists of a wireless sensor network,2013 cheapest cctv camera, gateway and the master control center. Wireless sensor network is a network of nerve ending, change is responsible for sensing the environment, and the data to the Internet through gateway. The system architecture is shown in figure 1.
ZigBee is a new short-range,2013 best wireless surveillance systems, low rate wireless network technology [l]. It is built on the IEEE 802.15.4t2I standard,types of cctv cameras, IEEE provides ZigBee physical layer and media access control layer,2013 u verse wireless receiver, network layer,wireless receiver module, application support sublayer and the application of high standards developed by the ZigBee alliance. The ZigBee protocol provides three available frequency band 868MHz, 915MHz and 2.4GHz,2013 hd security camera systems, respectively 1,2014 security cameras best buy, 10 and 16 A total of 27 channel. The 2.4 GHz for universal frequency,personal surveillance cameras, transmission rate of 250 KB / St 31. The overall design of the
greenhouse control technology with the development of the greenhouse agriculture emerge as the times require, and control of traditional detection methods are time-consuming and laborious, by computer represents the development gradually mature; cable transmission, facing the complex wiring, maintenance and upgrade difficulty, and the birth of wireless sensor network technology has brought a new revolution to it. This paper presents a design scheme of Intelligent Greenhouse Monitoring System Based on ZigBee wireless network technology, through the intelligent monitoring and real time control of the important factors affecting plant growth light, humidity, temperature, also can through the mobile phone text messages to inform the farmers. The paper introduces the development of application program based on ZStack, realized the remote monitoring, treatment and control of greenhouse. 1 ZigBee wireless network technology
2 systemThe structure of intelligent monitoring system of greenhouse based on Wireless Sensor Network
with automatic control theory as the theoretical basis, application of sensor and actuator to form a closed loop control system. The growth environment of sensor nodes equipped with sensors to plant, control node with actuator control device for improving plant growth environment. Sensor nodes and control nodes cooperate with each other, to provide suitable environment for the growth of the plant.
2.1 system
PC and real-time view data, control, thus to realize remote monitoring of real significance. Keywords: ZigBee; wireless network; sensor; greenhouse control; CGI
