Further, described air cleaning member also comprises:
Cleaning module, for will be zero level air through the air-treatment of this module.
According to above-mentioned a kind of air borne sensor zero point correction and the changing method detecting switching device shifter in real time, it is characterized in that, comprise the steps:
1) when needs to be calibrated air borne sensor zero point, following situation is included but not limited to: during starting device, equipment is when artificially needing in running or when device program regulation needs, processing module sends from detecting the signal being switched to zero point correction in real time;
2) the first air intake passage is closed, open ventilating duct, air draught under the effect of power source module from the second air intake passage successively through clean unit, ventilating duct and detecting unit, and flow out from the air-out passage of detecting unit, air borne sensor enters zero point correction state;
3) real-time measurement values of the zero level air that produces according to clean unit of processing module and record contrasts, and calibrates zero point air borne sensor with this;
4) when air borne sensor zero point correction is complete, processing module sends and is switched to from zero point correction the signal detected in real time;
5) close ventilating duct, open the first air intake passage, air draught enters detecting unit from the first air intake passage and flows out from its air-out passage under the effect of power source module, and air borne sensor enters real-time detected state.
Beneficial effect of the present invention:
The present invention controls the flow direction of air draught by the open and-shut mode controlling each air intake passage and ventilating duct, with the switching that this realizes air borne sensor zero point correction and detects in real time, the interference that the first air intake passage is conducive to eliminating external environment is closed, to obtain better calibration effect when carrying out the zero point correction of air borne sensor; The interference that the second air intake passage is conducive to eliminating clean unit is closed, to obtain better Detection results when carrying out the real-time detection of air borne sensor.The enforcement of this device and method will be conducive to people and obtain air quality situation more accurately in time, reduce because sensor zero drift causes the inaccurate inconvenience that brings of testing result and economic loss simultaneously.
