The smart greenhouse solution is to collect information in real time through the use of various sensor nodes in the greenhouse, such as the temperature and humidity in the greenhouse, the carbon dioxide in the air, and the nutrient content of the soil, etc., to help farmers accurately measure the various environmental parameters in the greenhouse for intelligent perception , Intelligent early warning and intelligent decision-making to achieve environmental control and precise management.
The indoor environment monitoring of the greenhouse can carry out real-time monitoring and precise regulation of the growth conditions of the crops in the greenhouse. The main parameters for detecting the growth conditions of crops in the greenhouse include soil temperature and humidity parameter values, indoor climate parameter values and real-time image data during monitoring. Soil temperature and humidity parameter values include soil moisture, soil ammonia concentration, etc.; climate parameter values mainly include wind speed, air temperature and humidity, CO2 concentration, etc.; real-time monitoring images include real-time collection of indoor images by WIFI cameras.
(2)Intelligent data acquisition
Intelligent data acquisition mainly refers to all kinds of sensors in the greenhouse. -Generally, it includes temperature and humidity sensor, illumination sensor, soil sensor, wind speed and direction sensor, carbon dioxide sensor, etc. They can monitor the greenhouse in real time, collect all kinds of data 24 hours, and upload the data to the monitoring center.
Intelligent irrigation is through the terminal greenhouse temperature and humidity sensor and soil moisture sensor data collection, according to the initial beyond the limit setting, automatic sensing and triggering irrigation device, irrigation operation, can also control the irrigation time through remote operation. At the same time, when the soil dry humidity is out of balance, the amount of sprinkler irrigation can be automatically adjusted to realize the humidity control of greenhouse soil.
(4)Intelligent air quality control
Intelligent air control is to collect data from greenhouse carbon dioxide sensor and greenhouse temperature and humidity sensor. According to the initial setting beyond the limit, it can automatically sense the gas content in the greenhouse, trigger and control the ventilation equipment, and change the indoor gas quality of the greenhouse through the automatic switch of the top window and side window to meet the needs of crop growth.
(5)Remote agricultural monitoring
Remote agricultural monitoring is a terminal operation based on B / S mode to control the greenhouse Internet of things. Through accessing the data center server of data collection, the user can access and query the same place on the network, view the operation of various sensors, monitor information and impose remote device control.
