Embodiment 1
[0047] see Figure 6 , is one of the embodiments of the control method of the gas flow control module 16, the gas flow control module 16 includes a gas flow detector and an exhaust fan, and its control method includes the following steps:
[0048] Step S11, the mobile platform 11 hovers, and the ambient gas collection channel 13 contains the current ambient gas sample;
[0049] Step S12, the ambient gas detection module 15 correspondingly detects the gas parameters in the current ambient gas collection channel 13;
[0050] Step S13, the gas flow detector detects the gas flow at the gas outlet of the ambient gas collection channel 13;
[0051] Step S14, providing a driving signal according to the detection result of the gas flow detector to drive the gas flow control module 16 to continue to work according to the set power, so that the gas in the ambient gas collection channel 13 is renewed;
[0052] Step S15, when it is detected that the gas in the ambient gas collection cha...
Embodiment 2
[0056] see Figure 7 , is another embodiment of the control method of the gas flow control module 16, the gas flow control module 16 includes a flow detector and an exhaust fan, and the control method includes the following steps:
[0057] Step S21, providing a control signal to drive the mobile platform 11 to move in the ambient space to be detected, the ambient gas collection channel 13 collects gas samples to be detected, and the ambient gas detection module 15 performs periodic detection of the gas samples to be detected;
[0058] Step S22, providing a control signal to control the gas flow control module 16 to be in the first working state;
[0059] Step S23, the gas flow detector detects the gas flow in the ambient gas collection channel 13, so as to calculate the actual gas renewal rate of the ambient gas collection channel 13 within a period of time. The target gas update rate of the ambient gas collection channel 13 is calculated according to the sampling interval of...
