Automatic temperature control system for greenhouse

Abstract

An automatic temperature control system for a greenhouse comprises a blowing device, a plurality of air outlet devices, a plurality of temperature sensors, a plurality of standard temperature sensors, a plurality of ports and a plurality of air supplying pipes, wherein the blowing device comprises a computing unit, a temperature acquisition unit, a temperature control unit and an air supplying unit, an air outlet of the blowing device is connected with air inlets of the air outlet devices through the air supplying pipes via the ports, or the air outlet of the blowing device is connected with an air inlet of another adjacent blowing device through the air supplying pipes via the ports, the air outlet devices are arranged in two rows, every two adjacent air outlet devices in the first row and every two corresponding adjacent air outlet devices in the second row form a rectangle, and the standard temperature sensors are arranged at the centers of the rectangles. The system is simple in structure, has diversified functions and can acquire temperature data in the greenhouse more reliably, the control accuracy is higher, the temperature in the greenhouse is uniform after being automatically controlled, and the crop growth environment 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. 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 automatic control of the internal te...
