Campus dormitory active noise reduction system based on window opening and closing and infrared induction

Abstract

The invention discloses a campus dormitory active noise reduction system based on window opening and closing and infrared induction. The system comprises a power supply, an infrared induction module,a window induction module, an active noise reduction module, an infrared induction switch and a noise reduction switch. The power input end of the infrared induction switch is connected with the powersupply; the power output end of the infrared induction switch is connected with the power input end of the noise reduction switch; and the power output end of the noise reduction switch is connectedwith the active noise reduction module. The infrared induction module comprises an infrared human body sensor and a first microprocessor. The window induction module comprises a second microprocessorand a plurality of opening sensors arranged on all windows of a dormitory. The campus dormitory active noise reduction system based on window opening and closing and infrared induction not only reduces noise influence due to opening, but also prevents unnecessary power resource wastes.

Description

technical field [0001] The invention relates to indoor noise reduction, in particular to an active noise reduction system for campus dormitories based on window opening and closing and infrared induction. Background technique [0002] In recent years, with the continuous expansion of the scale of higher education in our country, the number of school enrollment has continued to increase, and the campus dormitories have also been continuously expanded to facilitate student accommodation; some schools have campuses built in relatively quiet suburbs, but due to the consideration of convenient transportation, they are still There are some schools where the campus is relatively noisy, and a living area will be formed around the school itself. Noise is unavoidable. In the campus dormitory, the noise may have a negative impact on the campus life of the students and make the students irritable. , anxiety and other bad emotions; especially during sleep, if affected by noise, it is ver...

[0002] In recent years, with the continuous expansion of the scale of higher education in our country, the number of school enrollment has continued to increase, and the campus dormitories have also been continuously expanded to facilitate student accommodation; some schools have campuses built in relatively quiet suburbs, but due to the consideration of convenient transportation, they are still There are some schools where the campus is relatively noisy, and a living area will be formed around the school itself. Noise is unavoidable. In the campus dormitory, the noise may have a negative impact on the campus life of the students and make the students irritable. , anxiety and other bad emotions; especially during sleep, if they are affected by noise, it is very easy for students to wake up from sleep or sleepless nights, resulting in insufficient sleep and poor spirits, which is not conducive to students' normal learning

[0003] Therefore, for campus dormitories, noise reduction has become an urgent problem to be solved. Generally, noise reduction measures on campus are mainly passive noise reduction, such as soundproof windows, soundproof glass, etc., but in order to ensure the circulation of air , It is often necessary to open the windows for ventilation to keep the air flowing; after opening the windows, the passive noise reduction method cannot effectively isolate the environmental noise, which may adversely affect the students' study and rest, so active noise reduction in the dormitory is necessary , the active noise reduction in the dormitory generally requires power supply. In general, there are two ways to open the windows, one is to open automatically at a fixed time, and the other is to open manually. When the windows are automatically opened, there may be no students in the dormitory. In this case , the meaning of active noise reduction will waste power resources
