For large-scale greenhouse planting, manual management requires a lot of manpower, is labor-consuming, time-consuming, and there are unavoidable manual errors. Through the Internet of Things system, first of all, a large part of the manager's time and energy can be released and the efficiency can be improved. The same manual can manage the greenhouse several times, and accurate management can provide crop quality and increase revenue.
The system collects real-time environmental data such as air temperature and humidity , soil moisture, soil temperature, carbon dioxide, and light intensity in the greenhouse, and transmits it to the control center. The central platform system combines the latest monitoring data and preset environmental parameters suitable for crop growth. By comparison, if it is found that the data monitored by the sensor deviates from the preset value, the computer will automatically issue instructions to intelligently start the fan, shading, humidification, irrigation and other equipment connected to the system to work until the environmental data in the greenhouse reaches the system Within the preset data range, the related equipment will stop working.
Through the intelligent control system, the precise water and fertilizer supply according to the needs of the crop can effectively save the use of water and fertilizer, save resources and avoid waste, and damage to the land caused by excessive use. At the same time, it helps to save energy, reduce fertilizer pollution, improve the quality of agricultural products, contribute to agricultural energy conservation and emission reduction, protect the environment and develop a low-carbon economy, and the social benefits are very considerable.
Wireless communication technology LoRa technical characteristics:
As a long-distance communication technology of Low Power Wide Area Network (LPWAN), LoRa has received more and more attention in recent years. Cisco, IBM, Semtech, Microchip and others are actively promoting LoRa technology.
LoRa's strength lies in its long-range capabilities in terms of technology. LoRa technology's outstanding features in high performance, long distance, low power consumption, support for large-scale networking, ranging and positioning make the "terminal + gateway" an ideal technology choice for the large-scale application of the Internet of Things.
Climate and environmental parameter collection:
Through the Internet of Things system, sensors can be connected to collect ambient temperature and humidity, light intensity, wind speed, carbon dioxide concentration, etc.
Collection of soil environmental parameters:
Through the Internet of Things system, sensors can be connected to collect soil temperature, soil moisture, soil salinity, pH value, etc.
Application of intelligent control system:
Through the Internet of Things system, you can set the operating environmental conditions of various equipment in the greenhouse. When the environmental information does not meet the pre-defined conditions, the relevant equipment in the greenhouse is automatically started. Currently covers intelligent and precise control systems for water valves, intelligent control systems for precise air release, high-precision intelligent shutter control systems, intelligent fill light control systems, intelligent ventilation control systems, intelligent shading control systems, intelligent high-power control systems, and intelligent fusion systems Wait.
Agricultural monitoring system:
With the help of personal computers and smart phones, real-time monitoring of agricultural production site meteorology, soil, water source environment, and remote automatic control of agricultural facilities such as irrigation, ventilation, cooling, and warming in greenhouses, combined with live video, intelligent early warning, etc. Powerful functions can help the majority of agricultural workers to grasp the growth status of crops and environmental change trends anytime, anywhere.
