Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to embodiment provided by the invention, structure, details are as follows for feature:
As shown in Figure 1-Figure 3, a kind of no power consumption safe standby power control based on infra-red remote control, this device comprises reflector and receiver.Reflector comprises the infra-red code radiating circuit, is subjected to the infrared lasting luminous energy radiating circuit of on ﹠ off switch control.Receiver comprises that trigger-type power supply scanning circuit IC2, infrared ray receive decoding circuit IC1, relay triggers drive circuit IC3, all band photovoltaic detector CR.When pressing the on ﹠ off switch of reflector, the infrared light of reflector conveying capacity and infrared coding switching signal simultaneously directive photovoltaic detector CR and the infrared receiving tube D2 that is installed together on the receiver, the capacitor C of being responsible for energy storage in the circuit is recharged and makes+and the E terminal voltage rises when surpassing the predetermined value certain amplitude, and the trigger-type power supply scanning circuit IC2 in the circuit just is triggered to be made+and the E end provides electric energy to make its work with the Vcc termination is logical for infrared ray receives decoding circuit IC1; Infrared ray reception decoding circuit IC1 demodulates switch command rapidly and removes trigger relay drive circuit IC3; When making its voltage, capacitor discharge drops to predetermined value when following, trigger-type power supply scanning circuit IC2 ends, and no longer receives the Vcc end power supply of decoding circuit IC1 to infrared ray, no longer power consumption, infrared ray receives decoding circuit IC1 also because of the non-transformer supply quits work, and also no longer power consumption; But no longer need switch command just can keep conducting state after relay drive circuit IC3 is triggered, go direct electric consumption+E to drive relay J; Remove to control the next stage high power relay after the described relay J adhesive again, thus the work of control high-power electric appliance.
Before the present invention trigger-type power supply scanning circuit IC2 therein is not triggered, circuit does not have energy consumption, therefore, under normal indoor natural light or light, the very fast savings of storage capacitor C and keep 3V about voltage, and the luminous energy that remote controller sends only is responsible for the needs of capacitor C when 3V is raised to 3.2V.If frequently start shooting night, then need the time of remote controller unit's level second to start receiving circuit.As long as faint light or sightless infrared light are arranged, the all band photovoltaic detector all can charge to 3.2V for capacitor C, 3.2V be the voltage that circuits for triggering are started working, this moment is not if receive the infrared coding switching signal of remote control transmitter emission, just the relay drive circuit of back level does not obtain triggering, IC2 ended when the voltage on the capacitor C dropped to 3V, and entire circuit is no longer power consumption again.Go round and begin again, circuit power+E always scans between the 0.2V dynamic area of 3.2V at about 3V, at any time catch infrared coding switching signal from reflector, also has only again black night evening, if frequent switch, the lasting infrared luminous energy of launching on the remote control transmitter just plays the effect into the receiver transmission of electric energy, therefore the transmitting tube of being responsible for the infrared luminous energy of emission on the reflector also is controlled by ambient light detection circuit, this circuit is also connected after pressing on ﹠ off switch, whether elder generation's ambient light launches lasting infrared luminous energy in decision.
Below specify:
Reflector:
IC01 among Fig. 1 is code signal and constant infrared light control circuit, and be made up of two parts: a part is a coding circuit, by driving infrared-emitting diode D01 emission infrared encoded signal; Another part is the switching circuit that is subjected on ﹠ off switch control, drives the constant infrared light of infrared-emitting diode D02 emission.
IC01 and D01 form traditional infrared remote-control emitter, are responsible for coding, launch various remote control commands.The function of D02 is to increase on the basis of traditional infrared remote control transmitter.When pressing the on ﹠ off switch of reflector, on the one hand by the coded command of D01 emission switch, the switching circuit of notice driving D02 makes its emission infrared light for the D02 energized on the other hand, is used for providing electric energy to receiver.D02 only is controlled by the on ﹠ off switch on the reflector panel, with other function key onrelevant.
In the enforcement, done a module and a conventional emitter circuit that drives D02 separately and be connected in parallel.
Receiver:
Fig. 2 is an infrared remote control receiver that is independent of outside traditional electrical equipment.CR is all band photovoltaic detector, is used for receiving the infrared luminous energy that reflector D02 sends, and transfers it to electric energy and charges to capacitor C by diode D1, the main electric energy during in order to the deposit circuit working.IC1 and infrared receiving diode D2 form the infrared reception decoding module of little power consumption, and being responsible for provides the switch triggering level to trigger switch module I C3, and IC3 drives electromagnetic relay J adhesive.IC2 is a power supply scanning switch module, and+E power supply flows to IC1 by the switch control of IC2.The energy consumption of J adhesive is directly from+E.
The Zero-power-consumption standby problem is international technical barrier, and general electric appliance standby power consumption is all in 5W to 10W scope.The existing 1W standby electrical equipment of Japan, and latest report says that 0.1W treats that machine technology is about to walk out the laboratory.The technology of being known as Zero-power-consumption standby that has is to implant permanent battery in little power consumption chip.So long as acting just must need energy, no power consumption and to do work be non-existent.But stand-by time is very long, and the switching on and shutting down action but is in a flash, and the strategy of " A thousand days the country natures its soldiers and fall for one day's battle " is arranged greatly.Thus, define pure Zero-power-consumption standby, " in a flash " that the switching on and shutting down energy needed must be sent from switching on and shutting down instructions just sent to main frame from the outside and energy in a flash that the switching on and shutting down instruction is synchronous.Standby has the branch of safe and non-safety.Safe standby be exactly under the holding state circuit element and alternating current to reach air insulated; Non-safe standby is exactly alternating current loading or a connection electronic component under the holding state, even not power consumption also is non-safe standby.Electromagnetic relay is the electronic device that meets safe isolation standard, can isolate the implementation space between the contact.Yet realize Zero-power-consumption standby, also will drive an electromagnetic relay, by no means easy, this also is a biggest obstacle of having blocked all scientific research personnel, so at the electronic switching technology that all adopted non-safety to isolate in the machine technology treated of a lot of low-power consumption.The present invention has captured this obstacle finally, has developed the electromagnetic relay that arrives microampere order energy adhesive under the 3V voltage at 1V, with ingenious the combining of technology on the circuit of the present invention, has finally realized the notion standard of no power consumption safe standby.
Relay among the present invention is the ultra-micro power consumption axial symmetry rotary electric magnetic relay that not disturbed by gravity.Make the minimum power consumption technique device of mechanical energy generation significant change should first elect little power consumption stepping motor in the clock and watch core.If with the armature spindle is symmetry, the swing arm of double headed roller contact is installed thereon perpendicular to axle, can under the situation that stator and quilt suction gap between rotor remain unchanged, make the swing arm of contact-carrying that significantly angle variation is arranged, the outer end points of radius has also just had significantly change in location, as the contact of relay, can satisfy the requirement that safety is isolated easily.The operating current of pointer electron wall clock milliampere does not wait from hundreds of microampere to 2, and the operating current of pointer electron wrist-watch removes the power consumption of clock chip between 1.5 microamperes to 2 microamperes, and the power consumption of watch core stepping motor also will lack.The traditional electrical magnetic relay can't be accomplished very little very sensitive, can be subjected to the interference of gravity because of the variation of use angle.Also there is technology to make relay in addition with motor principle, but not the balanced quality of distributing swing arm of structure and axle both sides that the contact swing arm is installed with the armature spindle symmetry, when accomplishing little power consumption, during the hypersensitive state, also can be subjected to the interference of gravity because of the variation of use angle.
J among Fig. 2 is exactly little power consumption electromagnetic relay of the present invention's research.
Reasonable energy utilization, the IC2 module is taken on the important task of distribution energy.Reducing the only energy of energy consumption and reasonable distribution all is the important organic principle of system.The present invention has designed the IC2 module and the distribution of the energy has been used simple and clear way is arranged, and has play a part importantly to the effect that improves system.
It is how to reach target that this device work system below is shown:
The infrared light of the conveying capacity of reflector and infrared coding starting-up signal simultaneously directive infrasil photocell CR and the receiving tube D2 that is installed together on the receiver, capacitor C is recharged rapidly that (capacity of capacitor C can not be too big, otherwise can prolong the charging interval, be no more than 0.5 second and be advisable).Voltage on the capacitor C is in case surpass 3.2V, IC2 is triggered and starts working, open passage, general+E is transported to the Vcc end allows IC1 work, because of D2 in lasting recipient's infrared encoded signal, this moment, IC1 lost no time decode results is notified to IC3, the IC3 conducting that is triggered, J begins acting, and+E point current potential is reduced to 3V under beginning, and the IC2 closing passage no longer provides the energy to IC1, IC1 is stopped work, IC2 oneself also quits work and stops power consumption, and has left the electric energy below the 3V remaining in the capacitor C electromagnetic relay J of trigger switch IC3 control for, J is had remove to open the more powerful AC power self-lock switch of next stage enough pickup time.This moment, if on television set, using, the user be still as before strong according to channel, according to volume key, original infrared receiving terminal continues receiving the code signal that it is discerned on the television set, only is the power up function that has removed original CPU.The application of other electrical equipment is enumerated no longer one by one.
Fig. 3 is an application extension circuit of the present invention.
" IC3 and J " among Fig. 2 is extended to as " IC4 and J1 " in Fig. 3 frame of broken lines and " IC5 and J2 ".Wherein J1 is a normally opened relay, and J2 is a normally closed relay.The relay that has auto-lock function after the J1 adhesive for next stage is high-power is connected the power supply of solenoid, and self-locking stable state after the high power relay adhesive allows the contact of J1 adhesive to disconnect again.The normally-closed contact of J2 is to be serially connected with in the self-locking current supply circuit of high-power latching relay, and the contact is disconnected, and high power relay does not have the control power supply and discharges armature, makes controlled main appliance cut-off.Can give IC4 from " 1 " end output start-up command when therefore, IC1 receives starting-up signal; When receiving off signal, IC1 can give IC5 from " 2 " end output shutdown command.
Through last circuit application extension, the present technique invention has guaranteed to realize that the controlled household electrical appliance by 220 volts of power supplies of civil power have following operating state:
1, after remote controller sent start-up command, J1 moved adhesive, if civil power exists, high power relay is driven the adhesive self-locking, the work of household electrical appliance energized.
2, after remote controller sent start-up command, J1 moved adhesive, if civil power does not exist, high power relay can't adhesive (because civil power is used in self-locking), and the household electrical appliance non-transformer is connected and do not worked.
3, under electrical equipment normal boot-strap state, after remote controller sent shutdown command, J2 moved disconnection, and the high power relay self-locking circuit disconnects, and its armature discharges, and the contact disconnects, and the household electrical appliance non-transformer is connected and do not worked.
4, under electrical equipment normal boot-strap state, if outage appears in civil power, high-power latching relay outage discharges armature, and the household electrical appliance non-transformer is connected and quit work.Under this state, if the city power recovery normal power supply, household electrical appliance are energized automatically also.
More than 4 kinds of states, realized the safety of household electrical appliance use control.So the present invention is perfect on the result of control.
By above operation principle as can be known, the design of present technique invention is very rational.Not only realized infra-red remote control standby safety isolation zero-power, and 4 kinds of states of control result have also been realized the technical specification to the control safety requirements.
No power consumption safe standby telecontrol engineering based on infrared remote control technology is the telecontrol engineering that does not contain control such as the emitted energy that utilizes acoustic energy, alternating magnetic field and electromagnetic wave.Because infra-red remote control is that using the safest near human body, in people's living space also is to use the most general, suitable, ripe control media in the world at present.
After the controlled main electric equipment work, also need not provides power supply for this remote control.Infrared remote control receiver not only with the civil power spatial separation, and with controlled main electric equipment spatial separation, under the holding state, controlled main electric equipment has also been realized the spatial separation with civil power, and this can reduce dust for the electrical equipment inner body, reduce because of humidity makes dust and cause the components and parts life-span to reduce and reduce directly causing electric fault etc. to play an important role in the slight electrolysis in components and parts surface.Certainly, most importantly still brought huge safety to people's use.These three spatial separation combine on the remote control to be peerless, also to be based on the Zero-power-consumption standby telecontrol engineering of infrared remote control technology still more, have realized that real safety isolates Zero-power-consumption standby.
Standby energy consumption is a kind of inessential energy consumption, is the significant wastage to electric power resource.It has not only increased consumer's daily electricity charge spending, has wasted the national energy, has also destroyed environment.Minimizing and elimination standby energy consumption are causing the concern of society, become energy-saving and cost-reducing important topic, and the standby energy consumption problem is causing the very big concern of entire society.Reduce the standby energy consumption obligation and the responsibility of our each members of society just.In fact, also have in the society a lot of running environment preferably simple appliances can adopt non-safety to isolate standby mode, can remove electromagnetic relay J like this, the start level that translates with decoder directly drives the powerful electronic switch of next stage, it is a lot of that integrated circuit is simplified, can also make that the power consumption of receiver declines to a great extent in the present technique, finally can reduce the emitted energy of reflector again.
In a word, the technology of using this project not only can be integrated, improve existing electric equipment products, independently controls mains switch even if make, and its using value and scope also are also to be quite widely.
Above-mentioned with reference to embodiment to this based on the detailed description that the no power consumption safe standby power control of infra-red remote control carries out, be illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the general plotting of the present invention, should belong within protection scope of the present invention.
