Below the operation principle of above-mentioned television set is elaborated.
1) when television startup normally runs;
A) when the multimedia equipment 300 be attached thereto by+5V the power pins of HDMI is also normally run, micro-control unit MCU102 undo.
Power module 101 exports the voltage of 5V, is connected to the base stage of NPN triode Q4 by resistance R5, the grounded emitter of NPN triode Q4, and make NPN triode Q4 saturation conduction, then the collector voltage of NPN triode Q4 is about 0V; The collector electrode of NPN triode Q4 is connected with the base stage of NPN triode Q5, then NPN triode Q5 ends, and start control module 202 does not affect the state of television set.Simultaneously: power module 101 exports 5V magnitude of voltage, the base stage of PNP triode Q6 is connected to by resistance R6, + 5V the power pins of HDMI is connected to the emitter of PNP triode Q6, then the base stage of PNP triode Q6 and emitter voltage are all that 5V makes PNP triode Q6 end.
The voltage that power module 101 exports 5V is connected to the emitter of PNP triode Q1 by diode D1, the pressure drop of diode D1 is about 0.7V, then the emitter voltage of PNP triode Q1 is about 4.3V, and the base stage that+5V power pins of HDMI is connected to PNP triode Q1 by resistance R3 makes the base voltage of PNP triode Q1 also be 5V, then PNP triode Q1 cut-off; PNP triode Q1 ends, then NPN type triode Q2 cut-off, standby control module 201 does not affect the state of television set.
B) when the multimedia equipment 300 be attached thereto by+5V the power supply of HDMI enters standby;
The voltage that power module 101 exports 5V is connected to the base stage of PNP type triode Q6 by resistance R6, the voltage of+5V power pins of HDMI is 0V, then the emitter voltage value of PNP type triode Q6 is 0V, PNP type triode Q6 cut-off.
From A) part, power module 101 exports the magnitude of voltage of 5V, then the emitter voltage of PNP type triode Q1 is 4.3V, the magnitude of voltage of+5V the power pins of HDMI becomes 0V, make the base voltage of PNP type triode Q1 lower than the emitter voltage value of PNP type triode Q1, PNP type triode Q1 saturation conduction; PNP type triode Q1 saturation conduction makes NPN type triode Q2 saturation conduction from collector electrode output current by resistance R4, microprocessing unit MCU102 carries out standby process after sampling to standby control module 201 and start control module 202, and television set enters holding state.
C) when+5V power pins of HDMI does not have multimedia equipment 300 to connect,
+ 5V the power pins of HDMI does not have voltage, and power module exports the voltage of 5V, from A) part: NPN type triode Q5 end, and control module 202 of starting shooting does not affect the open state of television set.Power module exports the voltage of 5V, then PNP type triode Q6 ends all the time, and the base stage of PNP type triode Q1 is connected with the emitter of PNP type triode Q6, then the emitter voltage of PNP type triode Q1 is identical with base voltage, and PNP type triode Q1 ends; PNP type triode Q1 ends, then NPN type triode Q2 cut-off, standby control module 201 does not affect the open state of television set.
2) during television standby,
A), when the multimedia equipment 300 be attached thereto by+5V the power pins of HDMI is also standby, the voltage of+5V power pins of power module 101 and HDMI is all 0V; Then micro-control unit MCU102 does not carry out any operation, and television set maintains holding state.
From 1) B of part) part: standby rear standby control module 201 and start control module 202 do not affect the holding state of television set.
B) when the multimedia equipment 300 be attached thereto by+5V the power pins of HDMI enters start,
The voltage of+5V the power pins of HDMI is 5V, and the I/O mouth ADIN1 voltage of micro-control unit MCU102 is 0V;
+ 5V the power pins of HDMI is connected with the base stage of PNP type triode Q1 by resistance R3, is connected with the emitter of PNP type triode Q1 by resistance R1, a base stage emitter voltage of PNP type triode Q1 is all 5V, then PNP type triode Q1 cut-off, PNP type triode Q1 ends then NPN type triode Q2 cut-off, and standby control module 201 will not affect the holding state of television set.The cathode voltage of diode D1 is higher than cathode voltage simultaneously, and diode D1 reverse bias, prevents the voltage at+5V power pins place of HDMI to be that power module 101 is powered, and causes television operations abnormal.
+ 5V power pins the voltage of HDMI is 5V, power module voltage is 0V, makes the saturation conduction of PNP type triode Q6.The collector electrode output current of PNP type triode Q6 makes the emitter voltage value of PNP type triode Q3 become 4.3V immediately by diode D2, the base voltage of PNP type triode Q3 is lower than emitter voltage, PNP type triode Q3 saturation conduction, and power module voltage is 0V makes NPN type triode Q4 end, PNP type triode Q3 makes NPN type triode Q5 saturation conduction from collector electrode output current by resistance R11; NPN type triode Q5 saturation conduction, output voltage sampling rear the control television set of micro-control unit MCU102 to standby control module 201 and start control module 202 enters open state, and power module 101 is started working, and provides the voltage of 5V.
Before television set enters open state, the collector electrode of PNP type triode Q6 is connected with the collector electrode of NPN triode Q8, NPN type triode Q8 saturation conduction, and the emitter voltage of NPN type triode Q8 is about 4.3V; The emitter of NPN type triode Q8 is connected with the base stage of PNP triode Q7, then the base voltage of PNP triode Q7 is all the time higher than its emitter voltage, and PNP triode Q7 ends.
After power module 101 voltage becomes 5V, NPN type triode Q4 saturation conduction, the collector electrode of PNP triode Q4 and the base voltage of PNP triode Q5 are about 0V, and PNP triode Q5 ends, and start control module 202 no longer affects the open state of television set; Power module 101 voltage becomes 5V, and PNP type triode Q6 is ended; PNP type triode Q6 ends, then PNP type triode Q3 and NPN type triode Q8 cut-off, NPN type triode Q8 ends then PNP type triode Q7 saturation conduction, electric capacity C1 by resistance R14, PNP type triode Q7 repid discharge until complete, fully ensure that start control module 202 when television set is again standby multimedia equipment 300 again by standby enter start time can produce control action in time, reliably.
From 1) part A) part, when television boot-strap, standby control module 201 does not affect the open state of television set.
C) when+5V power pins of HDMI is not connected with multimedia equipment 300,
From 1) B of part) part is known: after power module 201 becomes 0V, standby control module 201 does not affect the holding state of television set, and start control module 202 does not affect the state of television set yet.
The embodiment of the present invention also provides a kind of television set, and television set comprises above-mentioned start and readiness control circuit, and above-mentioned start is connected with the multimedia equipment 300 of television set outside with readiness control circuit.
In the present invention, the output voltage of standby control module and start control module is subject to the control of+5V power pins voltage of HDMI, micro-control unit MCU samples and judges whether standby control module and start control module have output voltage, control television set according to judged result and carry out standby or open state, solve multimedia equipment when being connected with television set by HDMI, need by the manually opened television set of keying module or make television set enter holding state, make troubles to user, affect the problem of the experience effect of multimedia in business application.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
