See also shown in Figure 1, the television set that this creates a kind of Zero-power-consumption standby, other circuit of television set that comprise the television set Switching Power Supply and be connected with the television set Switching Power Supply.Wherein the television set Switching Power Supply also is connected with AC changes DC circuit and accumulator, and television set Switching Power Supply output 9V AC power is respectively to this two circuit; AC changes the output of DC circuit and is connected to relay, and accumulator is connected to relay by a thyristor, and this thyristor also is connected with the photoinduction circuits for triggering; Television set CPU connects the interchange readiness control circuit by an AND circuit, and this interchange readiness control circuit is connected to described relay, the trigger button of described relay control 220V urban electric power switch.
See also shown in Figure 2, AC changes the DC circuit and includes the first diode D1 and first capacitor C 1, wherein the positive pole of first diode connects the 9V alternating current of television set Switching Power Supply output, and the positive pole of first capacitor C 1 is connected with the negative pole of the first diode D1, minus earth.Accumulator includes the second diode D2 and capacitor C 2, and wherein the positive pole of the second diode D2 connects the 9V alternating current of television set Switching Power Supply output, and the positive pole of second capacitor C 2 is connected with the negative pole of the second diode D2, minus earth.The anodal accumulator that directly connects of thyristor Q1, the control utmost point is connected to the photoinduction circuits for triggering, and negative pole then connects relay.The photoinduction circuits for triggering include silicon photocell L1, with silicon photocell parallel resistor R2, the field effect transistor Q3 that is connected with silicon photocell, resistance R 2, wherein the positive pole that resistance R 1 connects accumulator second capacitor C 2 is passed through in the drain electrode of field effect transistor Q3, and source electrode is connected to relay by resistance R 3.Exchange readiness control circuit and include the second triode Q2, the 4th triode Q4 and resistance R 5, wherein the collector electrode of the second triode Q2 is connected to relay, grounded emitter, base stage links to each other with the collector electrode of the 4th triode Q4, the grounded emitter of the 4th triode Q4, base stage is connected to AND circuit.Resistance R 5 one is terminated between the second, the 4th triode, and the other end is connected to relay.AND circuit includes the 4th, the 5th diode D4, D5 and resistance R 7, and wherein the 4th, the 5th diode D4, D5 are connected to 5,6 pins of television set CPU respectively, and 5,6 pins of television set CPU also connect tuner M1.
See also shown in Figure 3ly, the remote controller of this creation also is equipped with the intense light source laser generator of low-power consumption except original Infrared remote controller circuit, and increases a button.With three kinds of states of television set definition: the interchange holding state that the 220v civil power disconnects fully (being called the Zero-power-consumption standby state), Switching Power Supply work but not the direct current holding state and the open state of start.Exchanging holding state, needing the circuit on duty of power supply to have only field effect transistor and thyristor, power consumption is extremely low, does not consume the 220v civil power fully, is powered by accumulator.Second capacitor C 2 is a storage capacitor in the accumulator, the storage capacitor of 10000UF can be kept power supply at least 24 hours in the application process, and the user generally can drive No. one time machine at least in 24 hours, and storage capacitor just can charging again before energy is lower than certain value like this.When under exchanging holding state, starting shooting, at first pin remote controller the corresponding button and open laser generator, aim at the silicon photocell irradiation of television set and can connect the 220V civil power in a flash, transfer the direct current standby to by exchanging standby, heel general television set is equally by treating the switch start.Operation during shutdown is identical with general television set, and by treating that switch makes television set enter the direct current holding state, (the countdown time can be provided with by the user) thoroughly closed short 220V civil power and entered the interchange holding state after the television set CPU countdown several seconds meanwhile.The user also can establish the countdown time longlyer, and such as two days, its benefit was that the machine of going on business for a long time transfers the interchange holding state to by the direct current standby automatically, avoids potential baked wheaten cake machine hidden danger.
See also shown in Figure 2ly, 5,6 pins of television set CPU output wave band switching signal is given tuner M1.Wherein, 3 wave band 5,6 pin level are only used 3 kinds of assembled state, and 5,6 pins all to be the state of high level do not use, utilize this State Control to exchange the IO mouth that standby can be saved television set CPU.Enter 5, the 6 pins output high level that exchanges holding state moment CPU, through the 4th triode Q4 saturation conduction after the AND circuit, and other the time triode Q4 all end.Thyristor ends under the interchange holding state, and capacitor C 2 voltages in the accumulator can't be added on the relay coil, and its contact disconnects, and 220V disconnects.If the capacitance voltage in the accumulator is higher than 5V, the user is by the silicon photocell L1 in the remote controller laser radiation photoinduction circuits for triggering, silicon photocell L1 exports the grid that the 3V high level is given field effect transistor Q3 immediately, make the field effect transistor drain-to-source that electric current be arranged, the high level of the control of thyristor, so thyristor Q1 conducting, the voltage of storage capacitor C2 is added on the coil of relay in the accumulator by thyristor Q1, because not power supply of CPU this moment, triode Q4 ends, then triode Q2 saturation conduction.Relay one closure, 220V exchanges and enters television set, and a winding output AC 9V voltage in the Switching Power Supply changes DC circuit output DC12V voltage through AC, is added to relay and makes it to continue closure, and promptly relay is in self-locking state.This moment, storage capacitor C2 also was charged to 12V, because the voltage that is added on the thyristor negative electrode anode is all 12V, the electric current that is flow to negative electrode by anode becomes 0, and less than holding current, therefore thyristor remains cut-off state under direct current standby or open state.220V exchanges and to continue to be input to television set after the relay self-locking, enter the direct current standby after the user can be by treating the switch start.
When the user controls television set and transfers the direct current standby to by start, television set CPU is 5,6 pins output high level (can be set the countdown time by the user in menu) after the countdown several seconds, the 4th triode Q4 saturation conduction, the second triode Q2 ends, relay contact disconnects, and television set enters the interchange holding state.Enter and exchange behind the holding state except several elements of circuit on duty, other circuit such as CPU has not just had power supply.The user also can be for a long time by treating that switch directly enters the interchange holding state by open state.Thyristor is owing to all end under direct current standby or open state, therefore transfers to exchanging that the voltage on the storage capacitor C2 is maintained behind the holding state, and television set CPU normal power supply under direct current standby, open state, it is also normal that 9V exchanges output.
If going on business, the user do not return above 1 day, television set surpasses 1 day and is not used, voltage on the storage capacitor C2 will be lower than 5V, can't make the relay adhesive, have only this moment by 220V is exchanged and enter television set, then relay obtains 12V voltage and closed self-locking enters the direct current holding state.Suppose to have the energy density of disturbing high light greater than remote controller laser, after disturbing strong illumination to cause television set to transfer the direct current holding state to by the interchange standby to silicon photocell, because the user is less than carrying out start in the several seconds that enters countdown at CPU, therefore television set can be got back to the interchange holding state automatically after the several seconds, and this has just solved the problem that the high light interference maloperation is done.
In concrete the application, use laser to trigger, also can use the intense light source of other concentration of energy to trigger, the laser generator type selecting can be with reference to the laser pen of teaching usefulness, and the power of laser should be limited in the direct projection human eye and not injure and be advisable.Silicon photocell is high more good more to the response selectivity of different wavelengths of light, and optical maser wavelength is dropped in the silicon photocell response wave length scope, or uses the filter part filtering interfering light identical with laser color, and filter is installed in the silicon photocell front.In addition, if the IO mouth of television set CPU is abundant, hardware designs also can be without AND circuit, and the direct output AC standby signal of certain pin of CPU is given the 4th diode Q4, control relay break-make then.
The button that remote controller is opened laser also can a compound function, promptly pin the infrared remote control instruction that also continues to send start when this key is opened laser, exchanging like this starts shooting under the holding state only need pin this key, the laser alignment silicon photocell promptly enters open state then, television set has been carried out two processes in fact, enter the direct current holding state after promptly receiving laser, and then CPU enters open state after receiving the instruction of standby turn-off machine at once.
The creation point of this creation is under the situation of circuit zero-power on duty, continue method closed, energising by moment light triggering (or signal triggering of other type) control relay and apply to standby zero-power scheme, this method circuit on duty is simple, what consume is quiescent dissipation, power consumption is extremely low, relay adopts latching circuit, only needs less energy drives relay closes moment can make it to continue closed, realizes real standby zero-power.Certainly, relay also can adopt other switching circuits, and storage capacitor can adopt other energy storage components and parts such as super capacitor, battery.
Most preferred embodiment described above only is that this creation is set forth and illustrated, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
