Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse automatic control system structure, and in particular to an automatic control system for blueberry cultivation greenhouse. Background Technology

[0002] The automatic control system for blueberry greenhouses is a system that utilizes advanced sensor technology, automation control technology, and computer technology to monitor and automatically control the environmental parameters and production process of blueberry greenhouses in real time. Through the automatic control system for blueberry greenhouses, precise regulation of the blueberry growing environment and automated management of the production process can be achieved, reducing the intensity of manual labor, increasing the yield and quality of blueberries, and reducing the adverse effects of changes in environmental factors on blueberry growth, thus providing a strong guarantee for high-quality and efficient blueberry production.

[0003] Automatic control systems for blueberry greenhouses typically consist of environmental sensors, soil sensors, controllers, ventilation equipment, shading mechanisms, supplemental lighting equipment, irrigation and fertilization equipment, and temperature control equipment. In existing technologies, the irrigation and fertilization equipment in these systems delivers fertilizer and water to the blueberry roots for fertilization and irrigation. Temperature is controlled by the greenhouse's air conditioning system, which exhausts hot and cold air into the greenhouse. However, this type of automatic control system has revealed several problems in practical applications: First, the sprinklers are evenly distributed, fixed in position, and uniformly opened and closed, lacking the flexibility and precision required for irrigation and fertilization. It cannot be customized to the specific needs of the blueberry bushes, and incorrect irrigation and fertilization of unnecessary bushes can negatively impact their growth and fruit production. Second, it lacks precise temperature control facilities. Adjusting the ambient temperature of the blueberry bushes requires adjusting the overall temperature rise and fall within the greenhouse, resulting in a slow adjustment process. Utility Model Content

[0004] The main objective of this invention is to provide an automatic control system for blueberry cultivation greenhouses, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

After adjusting the position of the nozzle 705, tighten the knob 707 in the threaded through hole of the sliding sleeve 706 to fix the position of the sliding sleeve 706. When adjusting the spray angle of the nozzle 705, loosen the knob 707, rotate the sliding sleeve 706, and then tighten the knob 707 to fix it. The sponge sleeve 708 makes the rubber sleeve 709 fit more closely to the outside of the infusion auxiliary pipe 702. The rubber sleeve 709 plays a role in anti-slip. The irrigation pipe 7 can adjust the position and tilt angle of the nozzle 705 and can be opened and closed independently. This allows the automatic control system of the blueberry greenhouse to carry out precise irrigation and fertilization according to the position of the blueberry tree roots. Blueberry trees that do not need irrigation and fertilization can be turned off independently.
