Abstract

The invention provides an intelligent ventilation device for a building, and belongs to the field of safe and intelligent buildings. The intelligent ventilation device comprises a TMS320F28335 main controller, a power supply module, an indoor air quality detection module, an induced ventilation module and a function selection module, wherein a digital filter, a high-frequency transformer, an output filter, a switch tube controller and a feedback circuit are adopted for the power supply module; an optical fibre dust sensor, an optical fibre oxygen sensor, an optical fibre humidity sensor and an optical fibre coupler are adopted for the indoor air quality detection module; the induced ventilation module comprises a rotational speed and flux linkage controller, a brushless direct-current motor and a fan impeller; and the function selection module comprises an automatic/manual selection key, a key speed adjustor and multi-row liquid crystal displays. The intelligent ventilation device provided by the invention is capable of accurately detecting an indoor dust concentration, an indoor oxygen concentration and an indoor air humidity of the building, greatly realizing automatic and manual ventilation, and suitable for being widely applied.

Description

technical field [0001] The invention belongs to the field of safe intelligent building construction, and in particular relates to an intelligent ventilation device for building construction. Background technique [0002] With the rapid development of the real estate industry, the number of urban buildings is increasing. In building construction, residents not only value the building format and layout, but also have high requirements for the lighting and ventilation of the house. However, in many buildings and buildings, there are poor ventilation, indoor humidity, and excessive airtightness; in addition, when the resident is decorating and cleaning the house, there will be a large amount of dust particles floating in the indoor air, which is harmful to the human body. The respiratory tract is extremely harmful; moreover, if the water and water vapor generated when mopping the floor are not discharged in time, the house will be damp; in addition, the long-term use of the air ...
