Working condition, describe the operation principle of stand-by circuit in detail, it is specific as follows：
In the case of blue Tooth remote controller control television boot-strap or in holding state, now bluetooth module power supply is
Battery supply VCC_ batteries；User presses the machine open/close button on blue Tooth remote controller, and the bluetooth module in television set passes through antenna
Starting up's signal that module receives, then, it is high level V0 that bluetooth module, which is inputted output I/O interfaces and drawn, now, the
Three switching tube Q3 base stages are high level, the 3rd switching tube Q3 conductings, the first switch pipe Q1 and the second switch pipe
It is low level 0V that Q2 grid voltage, which is drawn, now, the first switch pipe Q1 conductings, machine core board start, the second switch pipe
Q2 is closed, and bluetooth module power supply switchs to VCC_standby by VCC_ batteries；Press again machine open/close on blue Tooth remote controller by
Key, the input and output I/O interfaces of bluetooth module are pulled to low level 0V, and now the 3rd switching tube Q3 base stages are low level,
The 3rd switching tube Q3 is not turned on, and the first switch pipe Q1 and second switch pipe Q2 grid voltage is pulled up as height
Level, now, the first switch pipe Q1 are closed, and the second switch pipe Q2 conductings, bluetooth module is powered by VCC_standby
Switch to VCC_ batteries, machine core board standby voltage VCC_standby is closed, and now machine core board does not work, and its stand-by power consumption is zero.
In the case of key-press module control television boot-strap or in holding state, the input of the bluetooth module is defeated
Outgoing interface, i.e. I/O mouths voltage V0 are low level 0V, A/D sampling pin voltage V1=0V；After pressing standby button KEY, V1=
R3*VCC/ (R1+R3), VCC are VCC_ batteries；Now, bluetooth module detects the V1 after voltage value changes, makes I/O mouths electric
Pressure is drawn high as voltage V0, opens button KEY, now, the 3rd switching tube Q3 conductings, the first switch pipe Q1 conductings, institute
