In recent years, with the development of China's agricultural science and technology, food and clothing live line facilities to improve our quality of life, in eating organic food with excellent quality, by the people's recognition, entered the family dinner table. The popularity of organic vegetable greenhouses technology has been widely application. Organic greenhouses quantity increasing. For these vegetable greenhouses, in addition to the advantage of soil ability, its crop growth environment, such as temperature and humidity, illumination, soil temperature and humidity, CO2, conductivity of soil salt, etc., all need testing regulation, to keep the crop growth in the most optimal environment. Of these growth factors which can adjust the real-time and accurate detection is an important link in greenhouse vegetable production high quality, high yield. But how to effectively detect the vegetable greenhouses regulatory management, at present domestic mostly artificial, need to spend a lot of manpower and material resources and financial resources, and the efficiency is not high. Now the scale of farming, for larger quantity of greenhouse, traditional control measures will appear a lot of limitations.
Therefore, in modern vegetable greenhouses management usually environment automatic detection control system, to control the vegetable greenhouses growth environment, adapt to the needs of production. It with advanced technology and modern facilities, the environment control of crop growth conditions, make the crop growth is not affected by the influence of natural climate, perennial factory, with high efficiency, high output and high benefit.
Development of vegetable greenhouses environment real time monitoring system is designed for vegetable greenhouse intelligent monitoring system, can automatically monitor greenhouse indoor temperature and humidity, soil temperature and humidity, light, CO2, etc. This scheme combines the characteristics of greenhouse vegetable cultivation, using special sensor, timely and effective access to elements related parameters inside the greenhouse crop growth environment. Using this system, the management inside the greenhouse, can real-time understanding to the various environmental parameters variation in greenhouses, and under the guidance of NongKeZhan technical personnel to carry on the corresponding processing. For NongKeZhan technicians, also can timely access to multiple inside the greenhouse environmental parameters, and technical guidance, according to achieve the timely and efficient management of greenhouse
Four, system composition, working principle and scheme is introduced
Sharp research, who was laid in vegetable greenhouse production of temperature and humidity sensor, light sensor, co2 sensor, a soil moisture temperature sensor, the conductivity sensor and data collector of salt. Data collected information, such as the temperature humidity in the vegetable greenhouses, through wired or wireless way to send information, and will receive the information to the "farmers gas flux monitoring platform. If the greenhouse temperature and humidity of the current unfavorable to vegetable growth, with the progress of greenhouses administrator, so as to realize the intelligent management of greenhouse vegetables.
Monitoring system after installation, the operator can according to the real-time monitoring data of greenhouse interior heating, ventilation, CO2 generator equipment, effectively solve the modern intelligent greenhouse muscle operation cost is high, energy consumption, such as faults. Video monitoring system, can more intuitive image understanding to crop growth environment and growth. Waterproof and dustproof, this set of system to be able to run for a long time in high temperature and high humidity environment of greenhouse. Using wireless transmission technology, ensure in greenhouse steel structure building more in the stability of signal transmission.
"Farmers gas flux" system:
"Farmers gas flux monitoring and control system including sensor monitoring technique, data collection and transmission, video monitoring, PC client four parts: sensing monitoring: sensor with environment temperature, humidity, light, carbon dioxide, ground temperature, soil moisture, conductivity, salinity, etc.
Data collection, data collector, waterproof standard shell by 485 / GPRS mode for data transmission.
To agriculture is growing, soil moisture,'s, plant visualization remote automatic monitoring, such as farmland microclimate and crop video image information in real-time, automatic data collection, and for the information parameters for remote monitoring and network camera attitude, to adapt to the modern agricultural meteorological observation demands!
