Abstract

The invention discloses an intelligent agricultural greenhouse control system based on a central ventilation system. The intelligent agricultural greenhouse control system is composed of a PLC controller, a wind pressure adjustment system, a temperature and humidity adjustment system, a liquid crystal display screen, a carbon dioxide sensor, a light intensity sensor, and a camera, wherein the windpressure adjustment system, the temperature and humidity adjustment system, the liquid crystal display screen, the carbon dioxide sensor, the light intensity sensor, and the camera are connected withthe PLC controller. The wind pressure adjustment system consists of a wind pressure measuring instrument, a ventilation system and a blowing system. According to the intelligent agricultural greenhouse control system disclosed by the invention, the wind pressure in an agricultural greenhouse can be detected in real time and can be controlled automatically and circularly; the temperature and humidity can be controlled automatically; and the intelligent agricultural greenhouse is able to detect the soil pH value in the greenhouse as well as the photosynthetic intensity based on carbon dioxide in real time.

Description

technical field [0001] The invention relates to the technical field of intelligent greenhouse control, in particular to an intelligent agricultural greenhouse control system based on a fresh air system. Background technique [0002] my country is a large agricultural country. Since the reform and opening up, agriculture has been greatly developed, and it has achieved world-renowned achievements of feeding 22% of the world's population with 7% of the world's population. Greenhouses occupy a very important position in this large agricultural country, and my country's water resources are very short, and at the same time water resources directly restrict the development of agriculture, so intelligent irrigation in greenhouses is very important. The detection of temperature and humidity is an essential part of the intelligent irrigation technology. At the same time, temperature and humidity are closely related to human production and life, and are also the most common and basic ...
