The operation principle of above-mentioned specific embodiment is:
When inserting the use of AC220V electrical network and electrical equipment, as shown in Figure 1:
Usually controlled electric appliance and stand-by energy-saving automatic shutdown circuitry 2 all are in off-state, and the ultra-micro power consumption remote control boot-strap circuit 1 that resets is in " standby " state always.If need " start resets ", only need to use the infrared receiving terminal of remote controller (as usefulness such as the television set of household appliances or air-conditionings) the subtend economize on electricity energy-saving safe control device of arbitrary money electrical equipment, (or need the keying mode by the arbitrary key on the remote controller, but flicking the Reset button), hear the sound of " click ", insert controlled electric appliance internal communication power supply and stand-by energy-saving automatic shutdown circuitry 2 and all be in start "on" position (dynamically).
When the ultra-micro power consumption remote control resets boot-strap circuit 1 " standby ", integrated infrared remote control receives head and all exports high level, make the pulse power drive circuit be in cut-off state after the pulse trigger control circuit, the resetting coil L1 of magnetic latching relay does not have the pulse excitation electric current to pass through always; When pressing arbitrary key of remote controller, integrated infrared remote control receives head and receives specific infrared emission frequency with regard to output low level, and make pulse power drive circuit conducting when the ad hoc the Reset button of flicking (or) through the pulse trigger control circuit, thereby the start accumulation power supply that resets forms discharge pulse to actuation coil L1, make magnetic latching relay K-L1 contact adhesive be reset to " normally closed " state, the disconnection of K-L2 contact, at this moment insert the power supply and the stand-by energy-saving automatic shutdown circuitry 2 of controlled electric appliance and all connect the AC220V power supply; For further energy-conservation, reduce oneself power consumption simultaneously, because of the K-L2 contact disconnects, the start accumulation power supply and automatic disconnection resets.
After " start resets " energising, controlled electric appliance start subsequently operation routinely gets final product operate as normal.Simultaneously, stand-by energy-saving automatic shutdown circuitry 2 must be established beginning ultramicro power-consumption standby operation by cable.Beginning, power driving circuit is in cut-off state, and the shutdown accumulation power supply begins the energy storage of charging, and time-delay progressively boosts to the DC voltage-stabilizing value; On the other hand, along with the rising of direct voltage, the off signal sample circuit is also started working and is detected sampled signal, send the idle power-off supervisory circuit to monitor comparison process, and the result that will monitor send power driving circuit.The back controlled electric appliance start operate as normal if power on, stand-by energy-saving automatic shutdown circuitry 2 just always ultramicro power-consumption standby normally move.
As the controlled electric appliance shutdown of finishing using, or city's net AC220V burst has a power failure, the unloaded standby signal of the voltage that the off signal sample circuit will in time detect " change 0 ", send idle power-off supervisory circuit comparison process, if the standard value that is lower than the standby power that the energy-saving safe control device sets is (at the standby power grade in electric equipment products such as a large amount of household electrical appliances and office series different application field, can set by demand), then automatic time delay (can be on demand, set by the R-C circuit) high level of output makes the power driving circuit conducting, the shutdown accumulation power supply forms discharge pulse to actuation coil L2, magnetic latching relay K-L1 contact is disconnected, the adhesive of K-L2 contact is reset to " closure " state, insert the controlled electric appliance system power supply thereby cut off automatically, realize security appliance " Zero-power-consumption standby "; Because of the adhesive of K-L2 contact is reset to " closure ", the ultra-micro power consumption remote control resets boot-strap circuit 1 must be electric, is in " standby wait " state again; For further energy-conservation, reduce the oneself power consumption of control device simultaneously,, go back automatic disconnection shutdown accumulation power supply because of the K-L1 contact disconnects.Again start if desired, the arbitrary key (or the ad hoc the Reset button of flicking) that only needs to press remote controller gets final product.
After powering on, if controlled electric appliance fails in time to start shooting operate as normal, the idle power-off supervisory circuit (can be set automatic time delay on demand, time by the charging energy storage of shutdown accumulation power supply is determined) the output high level also makes the power driving circuit conducting, the shutdown accumulation power supply forms discharge pulse to actuation coil L2, make the disconnection of magnetic latching relay K-L1 contact, the adhesive of K-L2 contact be reset to " closure " state, insert the controlled electric appliance system power supply thereby cut off automatically, realize security appliance " Zero-power-consumption standby "; Because of the adhesive of K-L2 contact is reset to " closure ", the ultra-micro power consumption remote control resets boot-strap circuit 1 must be electric, is in " standby wait " state again; For further energy-conservation, reduce the oneself power consumption of control device simultaneously,, go back automatic disconnection shutdown accumulation power supply because of the K-L1 contact disconnects.Again start if desired, arbitrary key (or the ad hoc the Reset button of flicking) that the same need are pressed remote controller gets final product.
Ubiquitous " standby energy consumption " problem during the utility model is extensive use of at present a large amount of household electrical appliances, office electrical equipment, a kind of ultramicro power-consumption standby safety energy-saving control device is provided, by controlled electric appliance an intelligent control module is set at the energy-saving safe control device, intelligent control module comprises the power magnetic force keeping relay, the ultra-micro power consumption remote control that only need pulse excitation control reset boot-strap circuit and stand-by energy-saving automatic shutdown circuitry, and its connects controlled electric appliance input; Reset boot-strap circuit and stand-by energy-saving automatic shutdown circuitry of described ultra-micro power consumption remote control takes turns starting work, the stand-by energy-saving automatic shutdown circuitry is implemented monitoring and automatic disconnection electric system power supply to the controlled electric appliance standby, realize safety " ultramicro power-consumption standby ", simultaneously for further energy-conservation, reduce oneself power consumption, also automatic disconnection shutdown circuit accumulation power supply; The start that resets only needs the arbitrary button (or the ad hoc the Reset button of flicking) on the arbitrary money electric appliance remote controller of flicking can recover electric power supply, auto power off is implemented in shutdown to controlled household electrical appliances, office electrical equipment, make electrical equipment be in safety " ultramicro power-consumption standby ", do not change the custom that the user uses remote control (or keying) type household electrical appliances, office electrical equipment again.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.
