Second-hand smoke detection intelligent sound box

Abstract

The invention provides a second-hand smoke detection intelligent sound box, wherein the sound box comprises a sound box housing which is made of a smoke transmitting material and allows smoke particles to enter and exit; a detection device and an intelligent voice mainboard are arranged in the sound box; the detection device comprises an AT89C51 single chip microcomputer and an MQ-2 type smoke sensor; the signal output end of the MQ-2 type smoke sensor is connected to the signal input end of the AT89C51 single-chip microcomputer; the signal output end of the AT89C51 single-chip microcomputer is connected with the intelligent voice mainboard; the MQ-2 sensor collects combustible gas existing in the environment and generates resistance change, the resistance change is converted into a voltage value, the voltage value is input into an IN0 port of the ADC0809 chip, the voltage value is converted into a digital signal through the A / D module, and the digital signal is input into the AT89C51 single-chip microcomputer; the AT89C51 single-chip microcomputer is provided with a threshold value, if the input digital signal exceeds the threshold value, the intelligent voice mainboard is started, and sound is made through the loudspeaker. The intelligent loudspeaker box can detect cigarettes and prevent smokers from smoking in an intelligent voice conversation mode.

Description

technical field [0001] The invention designs an intelligent speaker, and in particular relates to an intelligent speaker that can detect second-hand smoke and prevent smokers from smoking through voice dialogue. Background technique [0002] According to the "2018 China Adult Tobacco Survey", the average exposure rate of second-hand smoke among non-smokers in China is 68.1%. In China, there is one smoker for every two men, and women and children are mainly harmed by second-hand smoke.

However, in real life, many children are suffering from the harm of second-hand smoke. Some young children have not even learned to speak, let alone how to express their feelings about cigarettes, so they can only let second-hand smoke harm their health

There are also some non-smokers who are also troubled by second-hand smoke, but they are unwilling or afraid to communicate with smokers face to face.
