Intelligent greenhouse system achieving self-adaptation adjustment of air humidity

Abstract

The invention discloses an intelligent greenhouse system achieving self-adaptation adjustment of air humidity. The intelligent greenhouse system comprises a first humidity sensor, a second humidity sensor, a ventilation module, a humidifying module, a control module, a storage module, a setting module and a display module. The first humidity sensor and the second humidity sensor are used for inducting the temperature inside and outside a greenhouse. The ventilation module is used for achieving air circulation inside and outside the greenhouse. The humidifying module is used for increasing the humidity in the greenhouse. The setting module is used for setting the expected humidity in the greenhouse. The storage module is used for storing the expected humidity. The display module is used for displaying the humidity and the expected humidity inside and outside the greenhouse. The control module is used for adjusting ventilating and humidifying of the greenhouse. The intelligent greenhouse system is simple in structure and convenient to use, the humidity can be automatically adjusted, the humidity in air outside the greenhouse is sufficiently utilized, and energy is saved.

Description

Technical field [0001] The invention relates to the field of agricultural automation control, in particular to an intelligent greenhouse system with adaptive air humidity adjustment. Background technique [0002] Greenhouse (greenhouse), also known as greenhouse, can transmit light, keep heat (or heat), and is used to cultivate plants. In the seasons that are not suitable for plant growth, it can provide growth period and increase yield. It is mostly used for plant cultivation or seedling cultivation of temperature-loving vegetables, flowers, forests and so on in low temperature season. [0003] There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions, such as glass greenhouses, plastic polycarbonate greenhouses; single-span greenhouses, multi-span greenhouses; single-roof greenhouses, double-span greenhouses Roof greenhouse; heating greenhouse, non-heating greenhouse, e...

Problems solved by technology

The impact on transpiration will indirectly affect the alternation of dryness and wetting of the pot soil, which is not conducive to fertilizer and water management; if the air humidity is too low for a long time, it will cause necrosis of the edge of the leaf and the tip of the leaf. The air pressure difference is too large, resulting in insufficient water vapor supply inside the leaves and necrosis

[0014] 2. The air humidity affects the opening and closing of plant stomata. If the air humidity is too high or too low, the stomata will close, and the plant stomata will close. CO2 cannot enter the mesophyll cells, and photosynthesis will slow down or even stop.

[0016] 4. High humidity will condense the water on the leaf surface, causing leaf cell rupture and weakening the plant

[0017] Existing greenhouse systems generally adjust the humidity manually, which is very troublesome. There are also computers to adjust the humidity of the greenhouse, but generally they are directly intervened, and the humidity of the external air is not used, which wastes energy.
