Intelligent greenhouse, the new development direction of modern agriculture!

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

What is a smart greenhouse

Intelligent greenhouse, also known as automatic greenhouse, is 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.

"Control System" is important in intelligent greenhouse

The "central system" of intelligent greenhouse is the 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 by the growth of various crops, it builds the intelligent soft and hard platform of the greenhouse, and realizes the automatic monitoring and control of the 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. It is suitable for seedling breeding, high-yield planting and cultivation of rare and rare flowers, so as to increase the output of greenhouse products and improve labor productivity. It is a successful example that high-tech achievements serve the modern agriculture of large-scale production.

Computer operators input the data and control parameters required by planting crops into the computer, and the system can realize unmanned automatic operation. The data collected by the computer can be accurately displayed and counted, providing reliable basis for experts to make decisions. The control cabinet is equipped with manual/automatic switch, which can be manually controlled when necessary.

How does the greenhouse monitoring system work

The computer collects various environmental parameters through sensors, combines the knowledge of agricultural expert system, makes decisions and gives instructions, and controls irrigation system, temperature regulating system, humidity regulating system, internal and external shading and light replenishment system and other equipment through manual, automatic and computer network (wired and wireless), so as to create suitable environmental conditions for crop growth and development. To achieve high yield, high quality and efficient production targets.

The system can be widely used in the production management of modern greenhouses, storage and preservation warehouses, breeding and storage houses and other agricultural facilities in various regions, so that users can truly appreciate the convenience brought by "science and technology serves agriculture". Through the use of the greenhouse monitoring system, farmers can feel that "no matter the wind and rain outside, the greenhouse is always good".

The application of Internet of Things technology in intelligent greenhouse

In fact, the Internet of Things technology is a kind of perception technology, modern network technology, artificial intelligence and automation technology aggregation and integrated application. In the greenhouse environment, a single greenhouse can use the Internet of Things technology to become a wireless sensor network measurement control area, using different sensor nodes and nodes with simple actuators, such as fans, low-voltage motors, valves and other low working current actuators, to form a wireless network. To measure the matrix humidity, composition, pH value, temperature and air humidity, air pressure, light intensity, carbon dioxide concentration, and so on, and then through the model analysis, automatic control of the greenhouse environment, control irrigation and fertilization operations, so as to obtain the best conditions for plant growth.

The application of Internet of Things technology in greenhouse can achieve the purpose of improving product quality, regulating the 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 labor, 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.

It is not difficult to see that the pastoral complex, leisure agricultural park and modern science and technology demonstration park will accelerate the promotion and application of the advanced technology of intelligent greenhouse in agriculture. Because these new agricultural economies have the capital, the technology, the talent, and the ability to use the new smart greenhouse technology to increase the value per unit of land output and maximize the benefits of the park.
