An automatic temperature control system for greenhouses based on light intensity control

Abstract

An automatic greenhouse temperature control system based on light intensity control comprises air blowing devices, multiple air exhaust devices, multiple temperature sensors, multiple standard temperature sensors, multiple interfaces and multiple air supply pipes. Each air blowing device comprises a calculation unit, a temperature acquisition unit, a temperature control unit, a light intensity acquisition unit, a driving unit and an air supply unit. The air supply pipes are connected with the air blowing devices and the air exhaust devices or connected with one air blowing device and another adjacent air blowing device. The air exhaust devices are arranged straightly in two rows. The two adjacent air exhaust devices in the first row and the two corresponding adjacent air exhaust devices in the second row form a rectangle, and the standard temperature sensors and correspondingly arranged light intensity detection sensors are arranged at the center of the rectangle. The system is simple in structure and diversified in function, temperature data in a greenhouse can be collected more reliably, control precision is higher, light intensity is controlled intelligently, the temperature in the greenhouse is uniform after being controlled automatically, and the growing environment of crops is stable.

Description

technical field [0001] The invention relates to the technical field of agricultural intelligent facilities, in particular to an automatic temperature control system for greenhouses based on light intensity control. Background technique [0002] With the improvement of people's living standards and the rapid development of my country's social modernization, people's needs for fresh and high-quality crops are becoming increasingly obvious. The way of using traditional solar greenhouse to produce crops is greatly affected by external factors, and the crops cannot be finely controlled. While increasing labor costs, the quality of crops cannot be guaranteed. Although the greenhouse is durable and resistant to natural disasters such as wind and rain, excessive solar radiation in summer, high temperature or low temperature in winter will damage the growth and development of crops. Therefore, through scientific management of greenhouses, greenhouses can be realized. The refined aut...
