Relationship.
Sub-step S30422：Determine that air blowing panel is the first kind in type set.
When the type of signal transmission unit 132 is the first kind, the second end of the second shift register and connection terminal 120
It mouthful disconnects, thus controller 110 is input to the test signal of signal transmission module 130 and is unable to normal transmission to connection terminal
120 second port, the test that the feedback signal at second port read to controller 110 is inputted with controller 110
Any correspondence is not present in signal.
Sub-step S30423：Judge whether feedback signal is identical as test signal, if it is, executing sub-step
S30424；If it is not, then executing sub-step S30425.
Sub-step S30424：Determine that air blowing panel is the second class in type set.
When the type of signal transmission unit 132 is the second class, since signal transmission unit 132 is only resistance at this time, no
It can change the direction of test signal, thus when test signal is high level, feedback signal is also high level, and test signal is low electricity
Usually, feedback signal is also low level.To when feedback signal is identical as test signal, just can determine that the type of air blowing panel
For the second class.
Sub-step S30425：Determine that air blowing panel is the third class in type set.
When the type of signal transmission unit 132 is third class, signal transmission unit 132 includes triode.To work as survey
When trial signal is high level, the second port of triode ON, connection terminal 120 is pulled down to ground by triode, at this time feedback letter
Number be low level；When test signal is low level, the second port of triode cut-off, connection terminal 120 is high level, i.e., instead
Feedback signal is high level.To when feedback signal is opposite with test signal, just can determine that the type of air blowing panel is third
Class.
