Automatic window opening/closing and gas detecting device based on SCM (Single Chip Microcomputer) infrared remote control

Abstract

The invention discloses an automatic window opening / closing and gas detecting device based on SCM (Single Chip Microcomputer) infrared remote control. The device comprises an information acquisition terminal and an operation executing terminal, wherein the information acquisition terminal is used for acquiring outdoor temperature information and a concentration of indoor harmful gas; the operation executing terminal is placed near a window and used for opening and closing the window; the information acquisition terminal comprises a first SCM microcontroller, 5V DC power supply, a temperature sensor, a gas sensor, a keyboard input circuit, a liquid crystal display circuit, a sound-light alarm circuit, an infrared emitting circuit and a first RS232 communication interface circuit; and the operation executing terminal comprises a second SCM microcontroller, a 12V DC power supply, a voltage conversion circuit, a relay switching circuit, an optical coupler isolation circuit, a motor drive circuit, a motor rotating unit, an infrared receiving circuit and a second RS232 communication interface circuit. The device has the functions of detecting the concentration of indoor harmful gas and opening or closing the window according to the outdoor temperature, and has functional completeness and high practicability.

Description

technical field [0001] The invention belongs to the technical field of single-chip infrared control, and in particular relates to a single-chip infrared remote control window automatic switch and a gas detection device. Background technique [0002] Nowadays, in hot climate areas, the air conditioner is turned on all night, which often causes people to feel uncomfortable during the day, and when the temperature drops in the middle of the night, people are too lazy to get up and open the windows, resulting in waste of resources and harm to their bodies, and indoor gas and natural gas leakage at night It is not easy to be noticed. There are still various risk factors surrounding our lives. For example, the formaldehyde content in furniture is a factor that endangers human survival. Once a danger occurs, corresponding measures must be taken immediately. Exhaust, remove danger, and protect life. The existing technology is to open and close the window manually by humans, and the ...

[0002] Nowadays, in hot climate areas, the air conditioner is turned on all night, which often causes people to feel uncomfortable during the day, and when the temperature drops in the middle of the night, people are too lazy to get up and open the windows, resulting in waste of resources and harm to their bodies, and indoor gas and natural gas leakage at night It is not easy to be noticed. There are still various risk factors surrounding our lives. For example, the formaldehyde content in furniture is a factor that endangers human survival. Once a danger occurs, corresponding measures must be taken immediately. Exhaust, remove danger, and protect life. The existing technology is to open and close the window manually by humans, and the data is transmitted to the controller of the window through the line. When danger occurs, once an accident occurs, people cannot immediately When danger is found, the room is large. Once danger occurs, human sensory nerves are not as sensitive as sensors, and they cannot detect or smell the leakage of dangerous gas at the first time, which will cause major danger, and may even be fatal; If a short circuit occurs, it will not be possible to control the window opening action in time
