Automatic control system for temperature in greenhouse

Abstract

Disclosed in the invention is an automatic control system for a temperature in a greenhouse. An indoor temperature sensing device collects current indoor temperature information, an outdoor temperature sensing device collects current outdoor temperature information, and a control center stores information of an optimum temperature for the crop; the indoor temperature information is compared with the optimum temperature for the crop; when the indoor temperature is lower than the optimum temperature, if the outdoor temperature is higher than the optimum temperature, forward air exchange by an air interchanger is carried out; and if the outdoor temperature is lower than the optimum temperature, a heating device is started; and when the indoor temperature is higher than the optimum temperature, if the outdoor temperature is higher than the optimum temperature and reverse air exchange by the air interchanger is carried out; and if the outdoor temperature is lower than the optimum temperature, forward air exchange by the air interchanger is carried out. The air interchanger adjusts the indoor temperature and the heating device carries out heating indoors. With the system, the manpower investment can be saved; the operation becomes simple and stable; and practicability is high.

Description

technical field [0001] The invention relates to an automatic control system for greenhouse temperature. Background technique [0002] Greenhouses, also known as greenhouses, can transmit light, keep warm and heat, and are mostly used to cultivate crops, so that crops can grow in seasons that are not suitable for growth, and such crops can be grown in areas that are not suitable for growing certain crops. The melons, fruits and vegetables planted in winter, as well as the ornamental plants planted in the north and south temperate zones, are a good solution to people's living needs for fresh melons, fruits and vegetables in winter, as well as their psychological needs for beautiful ornamental plants. However, in the process of planting crops in existing greenhouses, various factors are regulated and controlled by humans throughout the whole process. Human regulation and control are often not timely, especially in terms of temperature regulation in greenhouses. It will cause i...

Problems solved by technology

However, in the process of planting crops in existing greenhouses, various factors are regulated and controlled by humans throughout the whole process. Human regulation and control are often not timely, especially in terms of temperature regulation in greenhouses. It will cause irreparable damage to the planted crops and affect the final harvest. In view of these problems, there is an urgent need for a fully automated control system or solution to solve this problem
