Modern greenhouse fertilization technology is carried out simultaneously with micro-sprinkler irrigation, i.e., water and fertilizer are used, which can be done quickly and over a large area, and fertilization is uniform, labor-saving, time-saving, safe and avoids waste.

Greenhouse shading is the use of materials with a certain degree of light transmission to block part of the excess light, so as to ensure the normal growth of greenhouse crops need light, but also to prevent the excess solar radiation energy gathered in the greenhouse, resulting in high indoor temperatures. Greenhouse shading is divided into outdoor shading and indoor shading.

The greenhouse control system actuators include fans, air pumps, water curtains, shade curtains, solenoid valves and other equipment for regulating greenhouse parameters.

Greenhouse control is based on the temperature, humidity and light of the external environment, as well as wind speed, wind direction, rainfall and other climatic factors to control the temperature, humidity, ventilation and light in the greenhouse to create a suitable environment for crop growth. In actual control, the controlled quantities such as temperature, humidity and light will affect each···

Perception layer: Various sensors, such as temperature and humidity sensors, light sensors, carbon dioxide sensors, wind sensors, wind speed sensors, rain sensors, soil temperature and humidity sensors, etc., are used to obtain various types of information about plants. The sensing layer is the source of the IoT to identify objects and collect information.

Agricultural Internet of Things, that is, in the greenhouse control system, the use of Internet of Things system multi-temperature sensor, humidity sensor, PH sensor, light sensor, CO2 sensor and other equipment to detect the temperature, relative humidity, PH value, light intensity, soil nutrients, CO2 concentration and other physical quantity parameters in the environment, through a variety of i···

Daylight greenhouse intelligent control system is a complex system involving a variety of factors such as temperature, humidity, carbon dioxide concentration, light intensity and vegetable varieties. Therefore, the design of the system should have the following functions.

Intelligent greenhouse monitoring system integrates sensor, automatic control, communication, computing and other technologies with expert system. By pre-installing a variety of suitable environmental parameters required for crop growth, it builds a greenhouse intelligent software and hardware platform to realize automatic monitoring and control of temperature, humidity, light, CO2 and other facto···
