Abstract
The utility model discloses a standby power supply management device of a television. The standby power supply management device comprises a main power supply module, a video output device and a signal decoding module. When an external video input signal is interrupted or a remote controller is pressed again to input a signal, an MCU (Microprogrammed Control Unit) of a mainboard is used for timing, a signal decoding module can be used for interrupting a video signal of the video output device within a predetermined time length T, and the main power supply module continues to supply power for the video output device so as to enter a false standby state. If the MCU of the mainboard receives the external video input signal or the signal input by the remote controller again within the predetermined time length T, the signal decoding module restarts the video signal of the video output device; and otherwise, the main power supply module interrupts the power supplying for the video output device so as to enter a true standby state. By adopting the scheme, when the television needs to be turned on again, the television can be turned on only within a very short period of time. The standby power supply management device avoids the interruption (caused by misoperation) of the television in the process of normal playback.

Embodiment
In order to make the utility model technical problem to be solved, technical scheme and beneficial effect is clearer, understand,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the standby power management devices of the described television set of the utility model comprises main power source module 10, video output device 24, audio output device 36 and signal decoding module 34, mainboard MCU32.The standby power management devices can also comprise and showing with power module 20 and mainboard with power module 30; Main power source module 10 is processed into direct voltage (DC) with alternating voltage (AC); Show the direct voltage of handling the generation of main power source module 10 with power module 20; And video output device 24 supplied power, mainboard is handled the direct voltage of the generation of main power source module 10 with power module 30, and mainboard MCU32, signal decoding module 34 and audio output device 36 are supplied power.As stated, main power source module 10, show with power module 20 and mainboard with the power supply plan of power module 30 realizations television set.
As shown in Figure 1; The signal transmission of television set with controlling schemes is: mainboard MCU32 receives external video input signal or remote controller input signal; And send a control signal to signal decoding module 34 and decode, make video output device 24 and audio output device 36 work.The external video input signal can be VGA, the HDMI port with arousal function, and the remote controller input signal refers to press the infrared signal that produces behind the Power key of remote controller.When the external video input signal is ended or is pressed the remote controller input signal first; Mainboard MCU32 carries out timing and in preset time length T (as 60 seconds); Signal decoding module 34 continues the vision signal of output video output device 24; Main power source module 10 is ended video output device 24 power supplies through showing with power module 20, and television set gets into false holding state.In above-mentioned preset time length T (as 60 seconds); Mainboard MCU32 is as receive external video input signal or remote controller input signal once more; Main power source module 10 is through showing the power supply that recovers video output device 24 with power module 20; Signal decoding module 34 is decoded to audio signal again, and transmitting audio signal to audio output device 36; Otherwise main power source module 10 is through showing that mainboard MCU32 control signal decoder module 34 is ended the output of video and audio signal with 24 outages of 30 pairs of video output devices of power module, and television set gets into true holding state.And under true holding state, 10 pairs of mainboard MCU32 power supplies of main power source module, and end power supply for other electronic components.
To sum up, when television set is under the false holding state, signal decoding module 34 continues video output device 24, audio output device 36 and carries out the decoding output of signal.But main power source module 10 (perhaps showing with power module 20) is ended the power supply to video output device 24.When television set gets into the normal play state of television set by false holding state; The power supply that only needs to recover video output device 24 gets final product; Its time interval is very short; Can avoid owing to wrong extract by the Power key of remote controller or the mistake of video inputs mouth, and the overlong time of the content of TV program that causes missing.And get into true holding state by false holding state, and can finish the back by the automatic counting of mainboard MCU32 directly to get into, also can select to get into through the choice menus (as shown in Figure 4) of video output device 24.
Because mainboard MCU32 need receive external video input signal or remote controller input signal at any time.Under false holding state or true holding state, mainboard carries out voltage with 30 couples of said mainboard MCU32 of power module and often supplies.Be appreciated that television set under false standby or true holding state, signal decoding module 34 is ended the output of audio output devices 36 signals, and only under the situation of the normal play of television set, audio output device 36 is output audio signal normally.
As shown in Figure 2; The MP3389 that shows the MPS that can adopt with power module 20; This IC is the increment type controller of the driving White LED that has 12 passages of current source design, has the Burst PWM Dimming major functions such as (being the brightness of may command LED lamp) of protection and PWM or the direct input of DC of programmable overvoltage protection, disconnection and short circuit LED.It is to have an Enable Control Input pin that this IC also has an outstanding feature, through this Pin being controlled (with moving high level on this Pin to or pulling down to low level), can reach the function to the shutoff or the unlatching of LED lamp.
As shown in Figure 3; Mainboard carries out voltage transitions with the power module 30 main components and parts such as DC-DC and LDO that adopt; Thereby satisfy the voltage needs of each device of main, comprise mainboard MCU32 and signal decoding module 34 etc., wherein the power supply of mainboard MCU32 is normal confession; Through Enable Control Input pin is imported high or low level, whether can control other voltage output Vout.
As shown in Figure 4, be under the false holding state at television set, video output device 24 shows that the time span information and the user that get into false holding state select to get into normal video output or get into true holding state menu.Do not receive input signal once more when the television set long period (time can be made as 60 seconds); Prompting frame shown in Figure 4 can appear in video output device 24; Mainboard MCU32 also begins to carry out timing; The time showing of countdown on video output device 24, can directly be selected whether continue to watch (choosing " YES ", normal video output) immediately or get into true holding state (choosing " NO ") simultaneously according to prompting.
Above-mentioned explanation has illustrated and has described the preferred embodiment of the utility model; As previously mentioned; Be to be understood that the utility model is not limited to the form that this paper discloses, should do not regard eliminating as, and can be used for various other combinations, modification and environment other embodiment; And can in utility model contemplated scope described herein, change through the technology or the knowledge of above-mentioned instruction or association area.And change that those skilled in the art carried out and variation do not break away from the spirit and the scope of the utility model, then all should be in the protection range of the utility model accompanying claims.
