Hydroponic Greenhouse are generally glass greenhouses or solar panel greenhouses. Glass greenhouses are the most expensive and have the most advanced equipment among multi-span intelligent greenhouses.
Glass greenhouses are generally covered with double-layered hollow glass or single-layered glass, and the roof is generally covered with single-layered tempered glass or double-layered hollow solar panels.
To understand the difference between automation and intelligence, one must first understand the greenhouse's electrical system. Multi-span glass greenhouses are generally equipped with external shading systems, internal shading systems, internal insulation systems, fan and water curtain cooling systems, top-opening systems, side-opening window systems, internal circulating fan systems (depending on the greenhouse's length and width), automatic heating systems, supplemental lighting systems, carbon dioxide generators, and automatic water spray systems.
A computer system adds a set of logical thinking to the Greenhouse. Simultaneously, the environmental sensing parameters installed in multi-span glass Hydroponic Greenhouse include temperature, humidity, carbon dioxide concentration, and illuminance.
Within the computer, upper and lower limits for various environmental parameters can be preset according to the growth needs of the plants at different stages. Each parameter can be controlled independently by one or more systems.
The goal is simply for all the supporting systems of an Greenhouse (Emergency Greenhouse) to achieve electrical automation control. Manual switches are primarily used to control the operating system. Currently, the main parameter for sensor probes is temperature.
Fully automated greenhouses mainly control the start and stop of the water curtain fan system and heating system based on temperature sensors. They cannot coordinate and control other systems that may affect the ambient temperature.
Most of the Hydroponic Greenhouse currently under construction in my country are automated greenhouses, but are essentially semi-intelligent multi-span glass greenhouses.
Of course, there are also some Hydroponic Greenhouse for research, demonstration, or agricultural crop construction with extremely strict environmental requirements. Currently, my country's national conditions can promote the widespread adoption of automated greenhouses, which is already a significant step forward in the development of facility agriculture.
