Design And Application Based On The Internet Of The Desert PV Of Intelligent Greenhouse Control System

Agriculture Internet of things is the use of sensors and other terminal device, high efficiency of collecting field planting, horticulture, aquaculture and other agricultural production data information; establish wireless sensor networks for reliable data transmission. Finally, the information is fused and processed to realize the agricultural automation. At present, Zhongwei City, Ningxia Shapotou area utilization of solar energy combine greenhouse and photovoltaic power generation system, realize the combination of solar power generation and agricultural, construction of new photovoltaic greenhouse. How the Internet technology is applied into agricultural production efficiently and through the scientific and effective management, agricultural production processes to achieve more efficient, digital and networking, is the focus and difficulty we need to study at presentIn this paper, based on the information demand of agricultural production process, this paper takes the photovoltaic greenhouse as the research object, under the natural condition, by reforming the traditional greenhouse, using high precision sensor to collection temperature indoor air and the soil temperature humidity, carbon dioxide concentration and light strength, information, the application of Zigbee wireless, communication technology to build a wireless sensor network, and using Group State control software, achieved on greenhouse within environment of control, ensure crop normal of growth environment. The main tasks are as follows:(1) Carry on the on-the-spot investigation to the greenhouse, combine the reality, carry on the transformation to the greenhouse. In the open top greenhouse skylight, respectively before and after the increase of fan and wet curtain; the internal layout of irrigation pipe, installation of solenoid valve.(2) Analysis of the structure of the greenhouse, wireless communication technology, determine the layout of sensors in greenhouse program (Due to the large area of greenhouse, the greenhouse is divided into 16 smaller field control)(3) Low power, low cost, distributed and self-organizing feature make wireless sensor networks better and better. Using application of Zigbee CC2530 module as the core Board, build a wireless network, the wireless transmission of data.(4) Using industrial configuration software, Terminal monitor control system, the software is used to receive, save data and analysis the current data so as to determine the current environment of the greenhouse, and according to the plant growth needs to make the corresponding adjustment, controls the fan, skylight, pads and solenoid valve operation.The actual installation and application results show that IPC control can achieve real-time monitoring of greenhouse environment and save the data, According to these data, managers can judge the current environment and make adjustments in time to make the whole system run well, which meets the needs of managers for intelligent management and automatic control.
