Agricultural greenhouse indoor environment monitoring system based on embedded Internet of Things gateway

Abstract

The invention discloses an agricultural greenhouse indoor environment monitoring system based on an embedded Internet of Things gateway. The device structurally comprises a reservoir, a first plate-type catalytic layer, a second plate-type catalytic layer, a third plate-type catalytic layer, an ammonia gas storage tank, an ammonia gas ejector, an air inlet, a barrel, an anti-corrosion heat insulation layer, an expansion joint, a small motor, an air inlet valve, a first flue gas detector, a sealing ring, a stainless steel grid mesh, a three-way converter, a three-way valve, a second flue gas detector, a dust remover, an air outlet valve, and an air outlet port, wherein the expansion joint is connected with the air inlet; the air inlet valve is fixed at the air inlet; the first flue gas detector is connected with the cylinder body and is fixed at the air inlet; according to the present invention, the structure is simple, the production cost is low, the flue gas quality detection functionis provided, and the three chemical catalysis layers are added so as to effectively improve the flue gas online denitration efficiency.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an indoor environment monitoring system for agricultural greenhouses based on an embedded Internet of Things gateway. Background technique [0002] With the rapid development of social industrialization, the problem of pollution has gradually been paid attention to, and the large amount of fossil fuels used in factories is an important factor leading to the problem of pollution [1]. A large amount of carbon oxides and SO2 are emitted from the boiler flue of coal-fired power plants, which has a serious damage to the ecological environment and is the main cause of acid rain. It promotes industrial development and also causes huge economic losses. Therefore, how to reduce carbon dioxide and SO2 emissions from coal-fired power plant boilers without affecting the development of industrialization has become one of the urgent problems to be solved in our country. [0003] The pri...
