Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheat ventilation technology, specifically to an automatic temperature regulation and ventilation system for greenhouses used for four generations of wheat cultivation per year. Background Technology
[0002] As a long-day crop, wheat relies heavily on artificial lighting. LED lights provide specific wavelengths of light, such as red and blue, to simulate natural light and meet its photosynthetic needs. In artificial climate laboratories, wheat receives 22 hours of light and 2 hours of darkness daily, accelerating its growth cycle. Intelligent greenhouses, powered by the Internet of Things (IoT), use sensors to monitor environmental data such as temperature, humidity, and light intensity in real time. The intelligent control system then precisely adjusts these parameters to create the most suitable growing environment for wheat, significantly increasing its growth rate. The application has yielded remarkable results, drastically shortening the wheat growth cycle and enabling four generations of harvests per year, resulting in a significant increase in yield. In artificial climate laboratories, wheat yields can reach four times that of normal field planting. This technology not only provides an efficient pathway for wheat breeding and accelerates the development of new varieties but also increases grain output with limited land resources, playing a vital role in ensuring food security.
[0003] In existing technologies, the automatic temperature regulation and ventilation system for greenhouses with four generations of wheat per year has the following drawbacks: fixed-direction ventilation leads to significant differences in ventilation effects in different areas of the greenhouse. Areas near the ventilation openings experience high wind speeds and rapid temperature changes, while areas far from the openings have poor ventilation, easily creating a hot and humid environment that breeds pests and diseases. This results in inconsistent growth rates and quality of wheat in different areas. Therefore, we need an automatic temperature regulation and ventilation system for greenhouses with four generations of wheat per year. Utility Model Content
