Agricultural greenhouse capable of controlling internal temperature change based on internet of things

Abstract

The invention discloses an agricultural greenhouse capable of controlling internal temperature change based on internet of things. The agricultural greenhouse comprises a greenhouse door, wherein thesurface of the greenhouse door is rotatably connected with a rotating plate; the surface of the rotating plate is rotatably connected with a clock; a signal receiving plate is arranged on a side surface of the clock in a penetrating manner; the portion, which is positioned above the signal receiving plate, of the surface of the clock is fixedly connected with an iron block; a limiting tooth rod isarranged above a limiting ventilating tube; the right side of the limiting tooth rod is connected with a limiting gear in an engaged manner; a semicircular block is arranged on the inner surface of agraduated disc in a penetrating manner; the bottom of the semicircular block is fixedly connected with an air plug; a mercury pipe is arranged on the bottom of the air plug; and a mercury tank is fixedly connected to the bottom of the mercury pipe. According to the agricultural greenhouse capable of controlling internal temperature change based on internet of things, by cooperation of an annularheating channel and the mercury tank, a sensor is not required, and the agricultural greenhouse is simple to use and low in cost.

Description

technical field [0001] The invention relates to the technical field of greenhouse temperature control, in particular to an agricultural greenhouse based on the Internet of Things that can control temperature changes in the greenhouse. Background technique [0002] Agricultural greenhouse is a unique type of greenhouse in northern my country. It is an indoor vegetable growth greenhouse built with films and supports. Even in the coldest season, it can maintain a certain temperature and meet the needs of vegetable crop growth. Therefore, Agricultural greenhouses have become a necessary greenhouse for growing vegetables in winter, and a large number of vegetables are produced every year. [0003] In order to regulate the temperature of agricultural greenhouses, the existing agricultural greenhouses have been combined with the Internet to form a temperature control system based on the Internet of Things, but the existing temperature-controlled greenhouses based on the Internet of ...
