Intelligent greenhouse, the new direction of modern agriculture development!

With the rapid development of facility horticulture, intelligent greenhouse (usually referred to as multi-house intelligent greenhouse or modern greenhouse) comes into being. It is the advanced type of facility agriculture, with comprehensive environmental control system, which can directly adjust indoor temperature, light, water, fertilizer, gas and many other factors, so as to achieve high yield, steady fine vegetables and flowers all year round, and good economic benefits.

Intelligent greenhouse, also known as automatic greenhouse, refers to a high-tech "intelligent" greenhouse based on agricultural greenhouse environment equipped with computer controlled mobile skylight, shading system, insulation, wet curtain/fan cooling system, drip irrigation system or drip irrigation system, mobile seedbed and other automatic facilities. The control of intelligent greenhouse generally consists of three parts: signal acquisition system, central computer and control system.

The "central system" of intelligent greenhouse is intelligent greenhouse monitoring system. It is composed of sensors, automatic control systems, communications, computer technology and expert systems. By preloading the appropriate environmental parameters required for the growth of various crops, it builds the intelligent soft and hard platform of the greenhouse, and realizes the automatic monitoring and control of temperature, humidity, light, carbon dioxide, nutrient solution and other factors in the greenhouse.

Greenhouse temperature, humidity, light intensity and soil temperature and water content and other factors play a key role in greenhouse crop growth. Greenhouse automation control system is based on PLC as the core, using computer distributed network control structure for greenhouse

Computer operators input the data and control parameters required by planting crops into the computer, the system can realize unmanned automatic operation, accurate display and statistics of the data collected by the computer, providing reliable basis for expert decision-making. The control cabinet is equipped with manual/automatic switch, which can be manually controlled when necessary.

Water-saving irrigation measures such as drip irrigation and micro-sprinkler irrigation in greenhouses can reduce ground water collection, significantly reduce ground evaporation, and thus reduce air relative humidity. Similarly, the use of mulching film can also reduce ground water vapor evaporation: for example, after mulching film is covered in greenhouse, the relative humidity of greenhouse air decreases from 95% to 75% to 80%.

Intelligent logistics seedbed intelligent control logistics seedbed through digital twin mode, reasonable planning and layout form a complete logistics transportation system in the greenhouse, to achieve the transfer of seedbeds in different sections of the greenhouse, with high flexibility.

The application of Internet of Things technology in greenhouse can achieve the purpose of improving product quality, adjusting growth cycle and improving economic benefits, especially the efficient and accurate management of greenhouse. For large-scale greenhouse facilities, it takes a lot of manpower and time to control the environmental conditions in the greenhouse with the help of manual, and there are unavoidable manual errors. If the Internet of Things technology is applied, it only needs to click the mouse to complete manual operation in the shortest time, and it is very rigorous, which is also an important reason why the industry is optimistic about the application of the Internet of Things in modern agriculture.
