Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
As shown in fig. 1, the household air quality detection system of the present invention comprises a central controller, a power module, an all-in-one air quality detection module, an early warning device, a touch display screen, an air purifier, an air conditioner, and a humidifier;
the central controller adopts FX3SA-14MT-CM type programmable controller; the programmable controller can change the set air quality standard value through programming and automatically compare with the data transmitted by the receiving all-in-one air quality detection module to give an optimal solution.
The all-in-one air quality detection module comprises a temperature and humidity sensor for detecting temperature and humidity, an oxygen sensor for detecting oxygen concentration and a carbon dioxide concentration detector for detecting carbon dioxide concentrationThe device comprises a carbon dioxide sensor, a PM2.5/PM10 sensor for detecting the content of dust particles, a formaldehyde sensor for detecting the concentration of formaldehyde and carbon monoxide and a TVOC sensor for detecting the content of total volatile organic compounds, wherein the output ends of the temperature and humidity sensor, the oxygen sensor, the carbon dioxide sensor, the PM2.5/PM10 sensor, the formaldehyde sensor and the TVOC sensor are connected with the input end of a central controller; the temperature and humidity sensor adopts an RS485 type temperature and humidity sensor, and the oxygen sensor adopts O2-A2An oxygen sensor, wherein the carbon dioxide sensor adopts MG811 type CO2The sensor adopts a PMS 3003C type dust sensor as the PM2.5/PM10 sensor, adopts a ZP07-MP901 type dust sensor as the formaldehyde sensor, and adopts an SGP30 gas sensor as the TVOC sensor.
And the output end of the power supply module is connected with the input end of the central controller.
The output end of the central controller is respectively connected with the early warning device and the touch display screen; the early warning device comprises an LED warning lamp and a buzzer, the LED warning lamp and the buzzer are respectively connected with the central controller, and the early warning device can output an early warning or remove the early warning on an analysis result of the central controller. The touch display screen adopts an ET070 touch screen and is used for displaying monitoring data and indicating and operating the working state of the system.
The central controller is respectively communicated with the air purifier, the air conditioner and the humidifier through a wireless communicator, and the wireless communicator adopts a 2.4G wireless communication module. The wireless communication type air conditioner is connected with an external air purification device, an air conditioner and a humidifier and used for automatically controlling to improve the existing air quality and realize timely feedback adjustment.
The system operates as follows:
(1) the sensors effectively detect the current air quality in real time and acquire data, and simultaneously transmit the detection data to the central controller connected with the sensors;
