Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.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.
The utility model provides a kind of readiness control circuit of television set, comprising:
Energising under open state, the mainboard that under holding state, cuts off the power supply;
Be connected with mainboard, under open state, receive the standby signal that mainboard sends, the touch chip that under holding state, receives starting-up signal; And
Be connected with touch chip and mainboard respectively, mainboard implemented the AC/DC power supply of powering or cutting off the power supply for the touch chip power supply and according to the control signal that touch chip is sent.
The utility model also provides a kind of television set, and it has above-mentioned readiness control circuit.
The utility model utilizes touch chip to carry out the standby management, send standby signal by mainboard to touch chip, touch chip is according to the power supply of this standby signal control AC/DC power interruptions to mainboard, make under holding state, the touch chip power consumption is only arranged, realize the requirement of stand-by power consumption less than 0.5w.And this circuit need not increase any extra device, can not increase any system cost.
Be described in detail below in conjunction with the specific implementation of specific embodiment the readiness control circuit of the utility model television set:
Fig. 1 shows the electrical block diagram of the readiness control circuit that the utility model embodiment provides, and Fig. 2 shows the workflow diagram of the readiness control circuit that the utility model embodiment provides, and for convenience of explanation, only shows the part relevant with present embodiment.
With reference to the accompanying drawings 1, the readiness control circuit that present embodiment provides mainly comprises mainboard 1, the touch chip 2 of television set, and AC/DC power supply 3.Wherein, touch chip 2 control AC/DC power supplys 3 power on for mainboard 1 or cut off the power supply.Under open state if need standby, mainboard 1 can send standby signal to touch chip 2,2 control of touch chip AC/DC power supply 3 stops to be mainboard 1 power supply, television set enters holding state, under holding state, start shooting if need, touch chip 2 receives button or remote-controlled start-up signal, and control AC/DC power supply 3 begins to make television set enter open state for mainboard 1 power supply.In this circuit, mainboard 1 can have a plurality of signal inputs, output interface, comprising being connected with remote control dash receiver 4, can receive the remote control standby signal that remote control dash receiver 4 sends the first remote signal input interface, to touch chip 2 send standby signals output interface, can receive the input interface of the various keyed informations that touch chip 2 sends and the voltage input interface that is connected with a voltage output interface of AC/DC power supply 3.
In the present embodiment, touch chip 2 is preferably the MCU type, can receive infrared remote control, keying signal, thereby can open TV in the time of can guaranteeing standby, and the inside of touch chip 2 has memory, and a spot of EEPROM space is arranged, can preserve the preceding state of television set ac dump, i.e. open state or holding state.
With reference to the accompanying drawings 2, the operation principle of the readiness control circuit that present embodiment provides is as follows:
After television set exchanged start, touch chip 2 was carried out initialization, and this process generally needs the 100-200 millisecond, and in this process, touch chip 2 sends a low level control signal to AC/DC power supply 3, did not give mainboard 1 power supply earlier.Touch chip 2 can detect own inner memory then, reads the preceding state of television set ac dump last time, sees it is ac dump under the ideal case, or ac dump under the start situation, in two kinds of situation:
First kind of situation: be open state last time before the ac dump.
The first step, touch chip 2 is sent the control signal of a high level to AC/DC power supply 3, and control AC/DC power supply 3 gives mainboard 1 power supply, mainboard 1 beginning operate as normal.Memory is preserved this open state more then.
In second step, touch chip 2 begins to monitor the signal that mainboard 1 sends.Under the television set normal boot-strap state, mainboard 1 sends the signal of high level to touch chip 2; When the user requires standby or timing shutdown by remote controller or button operation, mainboard 1 sends low level standby signal to touch chip 2 after finishing the preceding preparation of standby, after touch chip 2 detects this standby signal, send low level control signal to AC/DC power supply 3, control AC/DC power supply 3 stops to mainboard 1 power supply.Memory is left this holding state simultaneously, and television set enters standby.
In the 3rd step, touch chip 2 detects whether keying or remote-controlled start-up signal are arranged, if do not have, then continues to detect.If receive starting-up signal, then send the control signal of high level to AC/DC power supply 3, control AC/DC power supply 3 is mainboard 1 power supply.Memory is left this open state, finishes a flow process.
Second kind of situation: be holding state last time before the ac dump.
At first, touch chip 2 keeps sending low level control signal to AC/DC power supply 3, does not give mainboard 1 power supply.
Then, touch chip 2 detects whether keying or remote-controlled start-up signal are arranged.One receives starting-up signal, just sends the control signal of high level to AC/DC power supply 3, and control AC/DC power supply 3 is mainboard 1 power supply, and memory is left this open state.
Then, touch chip 2 continues the flow operations according to step of second in above-mentioned first kind of situation and the 3rd step.
The utility model utilizes touch chip to carry out the standby management, send standby signal by mainboard to touch chip, touch chip is according to the power supply of this standby signal control AC/DC power interruptions to mainboard, make under holding state, the touch chip power consumption is only arranged, realize the requirement of stand-by power consumption less than 0.5w.And this circuit need not increase any extra device, can not increase any system cost.Simultaneously, this stand-by circuit has excellent adaptability, and to the restriction of mainboard without any the standby current aspect, practicality is very strong.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
