Desktop computing device is associated with a plurality of peripherals and other electric equipment that is associated usually, and wherein each is powered individually.Peripherals can comprise the thing such as printer, scanner and modulator-demodular unit, maybe may have the associate device such as desk lamp or indoor heater.
When computing machine was not worked, these peripherals generally were not used with related electric equipment yet.But, because they are power supplies separately, so the user also must close each peripherals and associate device when shutting down computer.This is a process of losing time, and if power switch be placed on many these type of electric equipment, then really can be extremely inconvenient.
Widely used computer operating system will be shut down computer power supply and needs the considerable time carry out some " internal affairs processings " task when not causing the situation of computer system problem being received between shutdown command and actual the shutting down computer or be in, and this also is the fact.At this moment, computer system may not allow peripherals is cut off the power supply yet.
Therefore many users allow optional equipment to continue energising simply after computing machine cuts out.
This is unfavorable for a plurality of reasons.First reason is that equipment continues power consumption, this not only costliness but also expensive source.This especially is a problem, because many modern comforts use the low-work voltage that little plug-in transformer provides them to be needed.When these plug-in transformers were connected to primary power, even the power switch on their institute's power-supply units cuts off, they still continued power consumption.Newer power supply uses solid switchgear, but still can consume about 0.5W.
All electric equipment have limited mission life, and if equipment when not using, be cut off, then its life-span can be extended to the longer time, this also is true.
Also is favourable from the primary power disconnection with the possibility that reduction is exposed to surge harmful the primary power with equipment when not required.
Prior art equipment has been attempted by providing relay to solve this problem, and relay cuts off the power supply of peripherals when no current flows to main equipment, and this main equipment is a desk-top computer itself.
Yet most modern desk-top computers have by entering one or more power consumption state, are commonly referred to the ability that holding state is controlled its electricity consumption.The user can allow equipment to spend the extended period in such holding state, thereby makes the advantage of prior art equipment invalid.

Realize optimal mode of the present invention
Forward Fig. 1 now to, show the skeleton view of electric controller according to an embodiment of the invention.Square frame 100 has comprised the operating circuit of this equipment.Electric wire 101 is connected to general electric delivery outlet.Electricity delivery outlet 102 is connected with the main linely connected power sup ply permanent electric of equipment.The main equipment of powering, promptly personal computer 111 in the case is connected delivery outlet so far.Main equipment can be that its state is determined any other electric equipment that the electric power of other associated device requires.
Power supply output 104 can be used for being connected to these electric loadings that only just require electric power when principal computer is in the full power pattern.Panel or switchboard 107 connect so far delivery outlet to allow in this manner to a plurality of power devices.Show this exemplary kind equipment, i.e. printer 112 and desk lamp 113.
Also have an electric delivery outlet 103 to can be used for connecting the load that when computing machine is in operation fully or standby mode, requires electric power but when principal computer cuts off, do not require electric power.Another panel or switchboard 108 connect so far delivery outlet to allow in this manner to a plurality of power devices.Exemplary such equipment is modulator-demodular unit 109.
Connectivity port 105 is used for serial communication cable is connected to this equipment.Switch 106 is called as " waking up/revise " switch, is set for and activates this equipment under the situation of this equipment self power down.
Consider Fig. 2, can find out the main functional modules of this equipment of block diagram form.Have main linely connected power sup ply inlead 201, it is to low-tension supply 202 power supplies.This power supply is to the electronic unit power supply of equipment.Main supply also is provided for PC supply module 203, and this module provides the output 204 that does not add switch to be used for main electric power devices, and this main electric equipment is desk-top computer normally.Surgesuppressor 202 these circuit of protection exempt from the main supply surge.
Main supply also offers controlled output 205 and 206 by switchgear 207 and 208.By the power supply of state sensor 209 monitoring to the delivery outlet 204 that do not add switch.State sensor will offer the input 210 and 211 of microcontroller 212 with desk-top computer consumed current and the proportional signal of voltage.
Therefore this microcontroller can be discerned the electricity consumption level of computing machine, thereby determines its duty.
Wherein electricity consumption be zero or low-down closed condition show that computing machine cut out or be in the inoperative power down mode.This state means that this equipment shuts down fully, shut down on the function, but still by its power supply with a small amount of electricity, or be in " dormancy " pattern.
Computing machine in the holding state is used significantly more electric than off-mode, but significantly lacks than its complete mode of operation.This may be that wherein some functional module (for example hard disk) is disabled because computing machine has entered standby mode, so it is with still less electric, but can respond user's input fast.This may be such a case also, and the user does not use a computer for a long time, but this computing machine is because standby time delay be provided with or do not enter standby mode because of the standby not enabled simply.
In another embodiment, the holding state that is caused by user's inertia can enter the holding state that standby mode causes with computing machine and be separated sign.This will be called as user's inertia holding state.
Also can identify other duty of different electricity consumption levels.
In opening, the computing machine executable operations.
Microcontroller identifies these three kinds or multimode more by the electricity consumption of monitoring computer continuously.Refer now to Fig. 6, it illustrates electricity consumption and the curve map of time 601 that is recorded by this equipment.
During the period 610, computing machine in use.Microcontroller monitoring electricity consumption is with dynamically definite baseline electricity consumption (being plotted as line 602 in Fig. 6), and this baseline electricity consumption frequently is offset to bigger value.This baseline value that has skew is powered controller and is identified as corresponding to opening.
The value of dynamically determining the baseline electricity consumption is that same energy-efficient equipment can use together with different parts of appliance, and need not to understand in advance the accurate electricity consumption corresponding to opening.This also means the parts of change system, and the more hard disk drive of power-efficient for example is installed, and can not make energy-conservation Device Errors ground think that computing machine has entered standby mode.
During the period 611, computing machine is held open, but does not use.It does not enter standby mode, may be because this function of user's not enabled.The baseline electricity consumption does not change as can be seen, but becomes seldom from the skew of baseline.When the skew long enough in the time fully after a little while, microcontroller is corresponding to holding state with this pattern-recognition.In another embodiment, it will be identified as user's inertia holding state individually.
During the period 612, computing machine enters standby mode.Power consumption significantly reduces.Microcontroller is identified as it indication holding state at once.
During the period 613, computing machine is closed or enters park mode.Power consumption significantly reduces once more, to very low or zero level.Energy-efficient equipment is identified as off-mode with this.
Microcontroller 212 is handled these signals, and only produces output signal 213 to connect first controlled switch 207 when opening is effective.When holding state or user's inertia holding state were effective, microcontroller produced signal to connect second controlled switch 208 at output 214 places.
Therefore only first controlled switch, 207 connections when computing machine is worked fully, and second controlled switch 208 is connected when computing machine is in unlatching or holding state.
Also be provided with communication module 215, it allows the direct data communication between desk-top computer and the electric controller.This can be used to upgrade any variable of microcontroller firmware to preserve in setting or the change microcontroller, or makes the calculating function directly bear the function and the direct gauge tap 207 and 208 of voltage and current detecting device 209 and 210.

Fig. 3 illustrates the circuit diagram of one embodiment of the invention.Main linely connected power sup ply plug 1 is powered to power-supply unit, and is power supply source, and this is powered by peripherals and the associated device switch of equipment to the computing machine laying apparatu.
Low-tension supply is illustrated as frame 7.It is made up of fuse 2, transformer 3, and wherein transformer has rail voltage primary coil and two 9 volts of secondary coils.The direct current rectification is provided by bridge rectifier 4 and linear voltage regulator 6.This provides 5 volts of stable direct supply V CC90, and+12V power supply 91 and-12V power supply 92.
Surge suppresses circuit 30 and is connected in parallel with this power supply.It utilizes three metal oxide varistors 29 that connect according to triangular configuration that the maximum voltage limit between any two lines is suppressed for rheostatic breakdown voltage rating provides surge.
Power supply to desk-top computer provides by electric delivery outlet 9, and this power supply provides by equipment of the present invention but can't help this facility switching.Neutrality connection to this plug comprises current-sense resistor 8.Exist current signal to regulate difference input amplifier 10.This with the benchmark of current signal therefrom sex reversal be ground connection.If so do not do, then neutral connecting line must be connected to the public terminal of power supply.Connect by any serial port, this may be connected to the neutrality or the ground wire of computer-internal power supply, and this can cause the mistrip of the residual current device of holding circuit.
The value of resistor 8 is selected as very little, to reduce the power consumption in the resistor.Therefore, need current signal amplifier 11 to provide amplitude enough big reference signal.Can under the control of microcontroller 24, disconnect to change this Amplifier Gain with one or more resistor 13 places in circuit or from circuit by control analog switch 12.
Further regulate current signal by circuit for signal conditioning 31.Any direct current offset in the output of capacitor erase amplifier, and resistor and two diodes provide electric current restriction and voltage clamp, so that near the fixed range the amplified current signal is in reference voltage V aref (i.e. the voltage at 60 places).Range of signal is VAref ± 0.3V.Current detection signal is applied to the analog to digital converter input 51 of microcontroller 24 then.
The active line and the neutral line of input are connected to resistive voltage divider 14, are applied to the voltage of desk-top computer with detection.Differential amplifier 15 moves to ground wire with the voltage signal benchmark from the neutral line according to the same processing mode that 10 pairs of current signals of difference input amplifier carry out.
This voltage signal is applied to regulating circuit 16 then, and it comprises current-limiting resistor and is the clamp diode of VAref ± 0.3V with signal limitations.This signal is applied in the input 52 to microcontroller 24, and this input 52 is configured to the second channel of analog to digital converter.
When voltage was positioned at zero, zero-crossing detector 17 provided signal to microcontroller 24.This makes microcontroller can guarantee the measurement synchronization of voltage and current signal.Effectively precise voltage benchmark 23 provides voltage reference.This reference voltage is applied in to the upper limit of microcontroller with the fixed die number converter.
Serial communication circuit 22 allows the connection of RS 232 serial ports.The power supply that solid-state relay 27 is controlled the power supply output that is provided with switch.The signal of switch solid-state relay 27 is to provide by transistor buffers 28 from microcontroller 24.When switch 33 is provided in this switch connection 53 ground connection are imported in the interruption of microcontroller 24.Software monitoring desk-top computer institute consumed current/power in the microcontroller, and it controls electric delivery outlet 25 and 26.
Microcontroller automatically detects and determines as above power level at the complete mode of operation corresponding to desk-top computer described in the description of Fig. 2, standby mode and complete shutdown mode.
Startup value corresponding to the power threshold of each identified duty of computing machine is stored in the EPROM.These values are used when starting by microcontroller, but constantly calculate new value based on detected computing machine electricity consumption.
When the microcontroller program determines that holding state is effective, to exporting 26 power supplies; When identifying opening, to exporting 25 and 26 power supplies.
Be applied to the input 51 of microcontroller and 52 voltage signal and current signal by collection, and the multiplication respective sample, and carry out correlation computations and calculate the desk-top computer power consumption.This power measurement provide than simple current measurement accurate the indication to the desk-top computer power consumption of Duoing because it has also considered any phase shift between electric current and voltage and the waveform.
Fig. 4 shows another embodiment of the present invention.This circuit is worked in the mode identical with the circuit of Fig. 3, wherein has following variation.
In some cases, when computer shutdown, the user may require computing machine and peripherals outage thereof.This is because when using the modern computer power supply of software switch, it still continues with a small amount of even be instructed to the shutdown back at computing machine.Alternatively, the certain user is learning that meeting is more comfortable under the situation that computing machine disconnects from main linely connected power sup ply.
In this embodiment, the electric delivery outlet 9 that does not add switch is replaced by electric delivery outlet 511, wherein the power supply of this delivery outlet is controlled by solid-state relay 512 by microcontroller 24.This is used for when microprocessor detects computer shutdown delivery outlet 511 and delivery outlet 25 and 26 outages.
When this took place, computer booting/shut down switch was invalid, because the delivery outlet 511 that computing machine connected is not switched on.In order to open PC, press interrupt switch 33, this will cause in the short time electric delivery outlet 511 power supplies (being 10 seconds in the case).If PC opens during this period, then electric current will be obtained by delivery outlet 511, and electric controller can work, in due course to delivery outlet 511,25 and 26 power supplies.
PC start/shutdown " soft " power switch can be removed, or is interrupted switch 33 replacements or additional.This is because PC bios (basic input/output system) is as long as can be configured to apply main linely connected power sup ply PC just " startup ", and does not need to press this fact of electric power starting/off switch.
What the user may not wish to occur powering closes fully.Therefore, provide firmware to allow two kinds of mode of operations.In one mode, switch 512 is worked as described above.Under second kind of pattern, switch 512 is connected always, and equipment turns round according to the mode the same with the circuit of Fig. 3.The firmware of microprocessor 24 allows to use interrupt switch 33 to pass on to adopt which pattern.Provide and interrupt expansion slot 517, to allow interrupt switch from the long-range placement of main electric controller.
Main equipment be not computing machine but for example audio-video device or cassette tape formula video recorder, maybe may be under the situation of micro-wave oven, may have the equipment of very a small amount of power supply that the needs such as real-time clock, time showing or infrared remote control detection device carry out always.
This very small amount of power generally can obtain from main linely connected power sup ply.This need be to the device power supply (DPS) continued power.Only the minimum power consumption to the power supply of these electric is about 0.5W.This may be to keep 50 times of the required real power of these functions that can not cut off the power supply.
In embodiments of the invention as shown in Figure 4, so a small amount of standby power demands can provide from the energy storage device such as rechargeable battery or storage capacitor.This energy storage device recovers the power supply to main equipment also to the trigger power supply to inform energy-efficient equipment.This allows energy-efficient equipment with aforesaid pattern work, wherein when detecting shutdown mode main equipment is cut off the power supply, and wherein also energy-efficient equipment self is cut off the power supply from main linely connected power sup ply.Device powers down is realized by main linely connected power sup ply control 700.This can be simple hand switch, and perhaps it can be the control circuit that is subjected to microcontroller 24 controls, as shown in Figure 7.
This also can be the relay of the main equipment control that is powered, or belongs to independently control circuit.
The details of the adjunct circuit of main linely connected power sup ply control 700 is shown in Figure 7.Battery activated functional block 710 detects main linely connected power sup ply and can use.But when its time spent, functional block 710 makes some the cell voltage at 709 places use, otherwise battery is disconnected.This guarantee when main linely connected power sup ply unavailable, thereby can not use main equipment the time, battery electric power can not be wasted yet.
The existence of main linely connected power sup ply provides enough electric current with turn-on transistor 703 by capacitor 702, and this again can conducting p type MOSFET 704.Electric power from battery 705 is available at point 709 places now.
When operation circuit 781 current potential step-downs, transistor 708 is with conducting.This can use to Vcc 90 cell voltage, and the energy-efficient equipment circuit is activated.
Functional block 711 will be powered to the energy-efficient equipment circuit now temporarily.Relay 718 is activated.Battery is provided directly to relay 718 by transistor 708.The RC network driving transistors 712 of resistor 713, resistor 717 and capacitor 714, transistor 712 is with relay 718 ground connection.Relay 718 is activated, and what its main line active line with input was connected to supply transformer 3 has a source terminal 701, as shown in Figure 4.
Vcc 90 is provided by main linely connected power sup ply now as described above.Provide trickle charge by resistor 707 and diode 706 to battery 705.
The existence of Vcc keeps transistor 712 conductings, and this guard relay 718 is connected, and continues energy-efficient equipment is powered.
Control line 780 is connected to microcontroller 24 by protection diode 716.Determine must be with main linely connected power sup ply when energy-efficient equipment disconnects when the microcontroller program, and control line 780 is got electronegative potential.Transistor 712 ends, thereby relay 718 cuts off.Energy-efficient equipment is de-energized, and inactive electricity consumption is reduced to zero.
For energy-efficient equipment is activated, control line 781 must become electronegative potential.This is by being realized by the Client-initiated external action usually.
The simplest method is the hand switch shown in 752.The temporary transient activation of this switch will start described program and make energy-conservation power on circuitry.
This switch can be the independent switch on the energy-efficient equipment, perhaps can be incorporated in the off/on switches of controlled plant.
Alternatively, can provide temporary transient low-potential signal on the control line 781 by receiver of remote-control sytem 753.Power supply---no matter whether main linely connected power sup ply is available by battery 705 for this remote control equipment.Receiver of remote-control sytem 753 detects by the use of Client-initiated to infrared or wireless remote control, and temporary transient electronegative potential is provided on control line 781.
When main controlled plant was audio-video device such as televisor, this was particularly useful.This kind equipment is opened by remote control usually.The remote control detecting device does not need the source codec from remote-controlled transmitter.The remote-controlled transmitter unit is enough to be used for showing that the user might require main equipment is powered.This has solved the subject matter that is subjected to remote control equipment that has standby power to require such as televisor.The user generally be unwilling the equipment of before using, manually opening and use after closing device manually.In the case, this device shutdown and do not have the standby electricity consumption, but when using remote control, open immediately, need not any additional user action.The regular event of the energy-efficient equipment of outage is carried out be unwilling the equally step of closing carried out of user when main equipment does not use.
When main equipment is the equipment of power supply with it such as laptop computer and external cell, then can adopt the circuit of functional block 754.The positive supply of laptop computer is connected to terminal 755, i.e. the public power of terminal 757.What be connected to terminal 756 is the control line of being controlled by laptop computer, its activity when laptop computer is opened.When this control line is movable, transistor 760 conductings, thus make the low and activation energy-efficient equipment of control line 781 current potentials.
As shown in the circuit of Fig. 4, current sensing resistor 8 can be replaced by current transformer 510.Its benefit is that current sensing signal and rail voltage electricity are isolated.This has eliminated the needs to the current signal resonance-amplifier.
By the rail voltage sensor 516 that is connected to supply transformer 3 is provided, also can get rid of differential amplifier 15.This rail voltage sensor provides rail voltage signal to regulating circuit 16, and this regulating circuit 16 is described as the embodiment of Fig. 3.
The output of microprocessor 24 is used for driven for emitting lights diode 502 to show the duty of equipment.Status message the hummer 504 that is subjected to microprocessor 24 controls also is set, so that can be communicated to the operator.
Switch 503 is set, and it should enter programming mode to allow to receive firmware update with the signaling microprocessor.
Signal from current transformer 510 is applied to current signal amplifier 513.This Amplifier Gain is controlled by utilizing control line 514 selected resistor 515 to be connected in the grounding path of amplifier by microprocessor 24.
The electric controller continuous monitoring is through the rail voltage of rectification, and the result is offered microcontroller.Microcontroller is programmed, if so that main linely connected power sup ply skew preset range reaches default duration, then switch 26 and 27 is worked according to so a kind of mode: all controlled delivery outlets are de-energized, and are stabilized in once more up to voltage to reach default duration in the preset range.This provides the overvoltage of main linely connected power sup ply and low-voltage variation.Electric controller is sampled to rail voltage, calculates real RMS voltage then.How this means no matter the supply waveform distortion all can correctly measure this value.This method also can correctly work for non-sinusoidal voltage, such as the voltage that is produced by some solid-state inverter.
The present invention can use in conjunction with the equipment of only observing and measure two kinds of power ratings, such as opening and closing or unlatching and holding state.Typical this type of electric equipment is that TV is listened equipment.In other words, at least two functional statuses that the needs by observation and measuring equipment or equipment group become, the present invention can be worked.
For example, audiovisual (AV) equipment can comprise a plurality of individual components, and such as TV screen, amplifier and DVD player, wherein each all requires to open so that this equipment operate as normal.The present invention is by the real RMS power of monitoring, and can be suitable for determining the various states of equipment and their power demand, thus when different means of attachment during to electric controller dynamically in response to the power requirement of variation.
In this manner, electric controller can be adapted to the variation demand of attached electric equipment.For example, the user may be at first be attached to electric controller with the power lead of televisor, and electric controller is determined two kinds of functional statuses of televisor then.The state of single television equipment determine that with described the same about computer equipment, but, the user may add additional electrical equipment after a while again, such as the amplifier that will be connected to TV.
When amplifier at first was opened, it presented standby mode.When applying main linely connected power sup ply, with " soon " speed measurement power consumption, and the standby power of extracting data equipment or cluster tool from then on.Employed Algorithm Analysis absolute power measurement and power swing are to have determined whether that any equipment is at work and disengaging standby mode in the electric controller.Lowest power measured value under the electro-mechanical wave situation of no use is stored as total standby power of TV and amplifier.This variable is increased specified quantitative then, shows that TV and amplifier all are in standby mode so that be lower than any power reading of this value.
This new value is called as " modified standby power level ".Any " noise " in this permission measured value or inaccurate.Reach certain hour when the power measurement values of equipment or cluster tool drops down onto modified stand-by level, for example 30 seconds the time, electric controller will make main linely connected power sup ply disconnect from the AV system.
When electric controller when all devices that places the turning off standby state is powered again, this standby power level is identified once more, guarantees not exist power swing simultaneously.
The disappearance of power swing is brought down below the minimizing that the standby value of calculating gained shows the number of devices that is connected with steady state power, and is lacking the increase that shows the electric number of devices that is connected to electric controller with the increase of the steady state power under the situation of electro-mechanical wave.
Television system is not cut off the power supply immediately but lacking under the situation that any remote control actions reaches 3 hour time for example, the AV system cut-off.Switch on once more to calculate the standby power level of this neotectonics.Fig. 8 illustrates the process flow diagram of the method for comparing with method shown in Figure 9, and method shown in Figure 9 is used for computer electronic equipment.
Fig. 8 illustrates method of the present invention, and wherein when first step 600, electric controller is found out the turning off standby power level, and this is equipment or a plurality of equipment employed power level or the add up power level attached with it.Electric controller is waited for (610) to receive the signal from remote equipment then, such as IR or the radiofrequency signal from remote equipment, and in case receives just to all affixation devices power supplies.
By the constantly electricity consumption and the detection power fluctuation (620) of the equipment of monitoring of monitoring in real time, system determines this device activity and is working then, and keeps the power supply (625) to equipment then.In step 630, if do not observe power swing, then electric controller determines whether power level mates with predetermined turning off standby level.
If supplying measure value and predetermined turning off standby level coupling, then the power supply to equipment is cut off, and system returns step 610 monitoring IR or radio frequency.If determine that equipment is not in the turning off standby level, such as the steady state power level that observes the inactivity fluctuation, then in step 640, system looks may be indicated any remote I R or the radiofrequency signal of use.If observe this type of signal, then keep the power supply of equipment is connected in step 625, if do not reach scheduled duration but observe signal in step 650 system, for example 4 hours, and do not detect action in the meantime, then system determines that the electricity consumption that is observed may be new standby power level, and all equipment is closed.System is again to these power devices and monitor the electricity consumption of these equipment then.If observe the steady state (SS) of inactivity fluctuation, then system determines that this is new standby power level.System is device powers down then, and continues in the step 610 monitoring to IR and radiofrequency signal.
In this manner, might add additional electronic devices to electric controller, or remove electronic equipment from electric controller, and system can constantly monitor the power demand that adds up of these equipment, and set up the required new turning off standby power level of these equipment when needed.This can become dynamically and the system of self-teaching system, is provided with and monitors any electricity consumption thereby needing to avoid the user constantly to change.
Therefore this electric controller can adapt to the variation of electricity consumption, because:
1. the power consumption of equipment in standby mode has very small power level fluctuation or not fluctuation.
2. the power consumption of equipment when work has significant power level fluctuation.
3. true EMS power be sampled and be measured to power supply control apparatus can in the very short time, therefore allows its monitoring power swing, and this power swing indicating equipment is worked but not is in standby mode.
Real RMS power monitoring needs electric controller can determine the duty of attached one or more electronic equipments.RMS power is the average measurement value that limits the power in the duration.In mains electricity is measured, be half (0.5) cycle, i.e. 10ms on the 50Hz of main linely connected power sup ply frequency to the minimum interval of determining the power measurement that power consumption is useful.Therefore, in this application, the transient measurement value of RMS power can be 10 milliseconds to the 5 seconds mean values on (usually less than 0.5 second).
Though illustrate and described the present invention with the content that is considered to the most practical and preferred embodiment in this article, but will be appreciated that and to make change within the scope of the invention, scope of the present invention is not subject to details described herein, but consistent with the full breadth of claims, to comprise any He all equivalent device and device.
