In the time that microcontroller 30 detects that Multi-position switch 10 is rotated counterclockwise, microcontroller 30 is exported the base stage that controls signal to the 4th triode Q4 of high level, control the 4th triode Q4 conducting, make infraluminescence pipe D1 transmitting infrared signal, infrared signal now sends to receiving system as anticlockwise order, and then receiving system is carried out the function corresponding with anticlockwise order, for example, when intelligent television receives anticlockwise order, the anticlockwise of intelligent television current screen, user in use, what naked eyes were seen will be that current screen moves to left, now can press center Touch control key 11 and be equivalent to by acknowledgement key by pressing center Touch control key 11() select the menu item in left side.The turn clockwise principle of situation of Multi-position switch 10 is same as described above, does not repeat them here.
When detecting Multi-position switch 10, microcontroller 30 is rotated counterclockwise the first touch point a1 place to rotary switch 12, center Touch control key 11 is pressed and is that discontinuous pressing (is that center Touch control key is not to be triggered always simultaneously, the 3rd I/O port IO3 of microcontroller 30 detects low level always) time, microcontroller 30 is exported control signal control the 4th triode Q4 conducting of high level, make infraluminescence pipe D1 send the first touch point a1 of rotary switch 12 command function pointed to receiving system, control receiving system and carry out corresponding function.The function that the first touch point a1 of for example rotary switch 12 points to is " volume adjusting " function, be rotated counterclockwise to the first touch point a1 place of rotary switch 12 at Multi-position switch 10, center Touch control key 11 is pressed, and now receiving system (as intelligent television) will enter volume adjusting interface.Multi-position switch 10 dextrorotations go to the second touch point a2 place or clockwise other touch points of rotary switch 12, and simultaneously center Touch control key 11 is pressed and is that the discontinuous principle of pressing situation is same as described above, does not repeat them here.
When receiving system is under ideal case, when Multi-position switch 10 center Touch control key 11 is pressed in Preset Time (as 30s) always, the 3rd I/O port IO3 of microcontroller 30 will be consecutively detected low level detection signal, now microcontroller 30 will send power-on command to receiving system by infraluminescence pipe D1, control receiving system and enter open state by standby.
When receiving system is in start situation, when Multi-position switch 10 center Touch control key 11 is pressed in Preset Time (as 30s) always, the 3rd I/O port IO3 of microcontroller 30 will be consecutively detected low level detection signal, now microcontroller 30 will send standby command to receiving system by infraluminescence pipe D1, control receiving system and enter holding state by start.
