I believe you can't be more familiar with what the greenhouse looks like. It's just a simple house built of plastic film, glass and PVC board. Have you seen what the smart greenhouse looks like after the collision between intelligence and greenhouse? Let's get to know Yuhua Xiaobian with you.

Taking the intelligent glass greenhouse as an example, it includes greenhouse environmental monitoring system, soil moisture monitoring system, shading system, ventilation management system, wet curtain cooling system, water and fertilizer system, light supplement system, CO2 regulation system and video monitoring system. Combined with the Agricultural Internet of things platform, it improves the mechanization and intelligence to the greatest extent. The components include:

Environmental monitoring equipment

The greenhouse environment monitoring adopts industrial Internet of things sensors, including air temperature and humidity, illumination, CO2 concentration, etc. the sensors can be distributed in each monitoring area inside the glass greenhouse in wired 485 mode or wireless Lora mode to monitor the data of crop growth environment, quantify the environmental data of crops in different growth stages, and communicate with the intelligent monitoring cabinet of the Internet of things, The real-time monitoring data will be transmitted to the cloud intelligent greenhouse monitoring platform to accurately control the comfort and suitability of the crop growth environment through the control equipment inside the greenhouse.

Sun shading system

Due to the excellent light transmission performance of glass greenhouse, the shading system plays an important role in sunlight control and indoor environmental temperature and humidity control. In summer, the use of sunshade can block the sun, which can prevent excess solar radiation from entering the greenhouse, not only ensure the normal growth of seedlings, but also reduce the indoor energy accumulation, reduce the temperature in the greenhouse, protect crops from strong light burns, and reduce the indoor temperature by 3-5 ℃; In winter, the sunshade has the function of reflecting indoor infrared escape and reducing heat dissipation, so as to maintain indoor temperature, reduce energy consumption and reduce winter operation cost.

In addition, the sunshade can also reduce the unrestricted escape of indoor water vapor, effectively maintain air humidity, reduce irrigation water, save fertilization, control crop harvest period and increase crop quality.

The internal and external sunshade system of the intelligent glass greenhouse can be automatically turned on and off according to the outdoor illuminance sensor data and indoor ambient temperature and humidity data, and can also be turned on and off regularly in winter and summer to achieve full-automatic regulation.

Ventilation management system

Remotely collect the value of the internal humidity sensor. When the humidity is too high, self-service start the circulating fan to adjust the indoor humidity. The circulating fan can also be turned on or off according to the degree of oxidation. Staff can also remotely control the fresh air ventilator through mobile app / computer platform to realize ventilation.

Water and fertilizer system

Realize the automatic allocation of phosphorus and potassium fertilizer and a variety of nutrient solutions, the allocation of pH auxiliary solution, detect the pH and EC parameters of the outlet pipeline, set timing irrigation and rotation irrigation, and operate remotely through the mobile app / computer platform.

Fill light system

When the illumination of crops is insufficient or too strong, fill the light of crops by manually / regularly controlling the fill light, or automatically fill the light according to the data of light radiation sensor and illuminance sensor.

"Smart agriculture" is to make full use of the achievements of modern information technology and integrate computer and network technology, Internet of things technology, audio and video technology, 3S technology, wireless communication technology and the wisdom and knowledge of relevant people to realize intelligent management such as visual remote diagnosis, remote control and disaster warning of Agriculture.
