On one side, can be carried out by the equipment or HEM with the communication of energy meter scale (such as power/energy measuring apparatus).
HEM can know when in advance to indicate or order HVAC to open.For example, the first two that HEM may be referred to
Circulation, and assessment reaches " the total shut-in time " between these circulations of the estimation time started of next circulation.This will pass through
The ending time for increasing " total shut-in time " to last circulation is to estimate the starting completing of next circulation.Alternatively, thermostat
HEM can be linked to, or in HEM may being built into and can pass through to estimate that the rise time in room provides next circulation
The following estimation for starting.This by by the circulation before checking with set up HVAC closing circulation during curve of the temperature to the time
To complete.By the curve matching data, HEM can estimate the time started of next circulation.
In one embodiment, HEM can obtain reference power metering meter reading before energy dissipation device circulation is opened,
It is then transported on order to record the power level readings of after the circulation starts (after such as starting about 30 seconds).This can allow
Time enough occurs for any extreme power spike caused as initial pressure is drop-down.However, when system pressure is further
When stable and environment temperature is more closely close to set point, the watt of the part of unit (such as compressor) is extracted in operation circulation
Period exponentially continuously can decline, it means that less load in HVAC system.So, the single reading of energy meter scale
Desired accuracy is necessarily provided.In order to obtain more accurately measuring for the power consumption of HVAC system, some rule of measurement can be used
Determine power consumption data of the frequency acquisition from gauge table, and the mean power that the data obtained can be processed to obtain HVAC is extracted
More preferable approximation.The disclosure provides several embodiments of algorithm, and which can be used for processing data and carrys out the flat of approximate HVAC system
Equal power extraction.These algorithms may further include when it is determined that during curve chart identification be above standard the exceptional value of deviation limit,
And extract these points.
In one embodiment, after can be by setting up based on starting including indoor temperature, outdoor temperature, operation circulation
Time, fine day in time period, one day to cloudy day amount, the parameter of length of the cycle before and/or real time power consumption and as when
Between the standard deviation of either side of meansigma methodss of the first and second power levels of energy dissipation device of function and mobile flat
The chart of average is determining or recognize exceptional value.
Fig. 2 illustrate for determine home network self-energy consume equipment and/or multiple energy dissipation devices (as electrical equipment/
HVAC unit etc.) in energy dissipation device special part energy/power consumptions profile embodiment.For example, energy
Management system can search the variable power (power consumption such as two or more power consumption levels is poor) consumed in given time frame, then
When the object variations specified are experienced in the time frame, (i.e. power has reached certain target asymptotic condition or slope) rests on
The power.For example, slope 1 can be determined by the difference of the power level by watt to time interval, slope 2, slope 3 and/
Or slope 4.Then the power level consistent with specified target change or slope (such as slope 4) can be assigned as mean power.
Then the power can record and/or be reported as the average power consumption of the part of equipment and/or equipment, so as to intimate approximate integration
Average power consumption.In order to determine that, by " target slopes " of best approximate " true average ", system is applied in hereafter next section
The scheme of description is determining the true average of watt-time graph.Then known to be somebody's turn to do " true average " power, system can be counted
Slope of the watt-time graph at the curve point with the value corresponding to the true mean power is calculated, and uses the slope
As " target slopes " of subsequent mean power measurement.The similar process is approximate in the acquisition that the embodiment with reference to Fig. 4 is described
Time " reading " watt consistent with " true average " power.
Fig. 3 is illustrated for determining that home network self-energy consumes equipment and/or the energy in multiple energy dissipation devices disappears
Another embodiment of the energy/power consumptions profile of the special part of consumption equipment.HEM systems are circulated before can determine
(as first or initial cycle) length and assume previous cycle (such as second circulation) will be it is similar, then using estimate
Terminal (can be determined based on ramp rate of the temperature to the time or the persistent period based on power ON cycle before), be obtained
The power consumption figure strong point of the multiple particular point in times in circulation, such as enters the intermediate point of previous cycle 30 seconds, previous cycle (based on it
Front length of the cycle) and the time point after intermediate point, such as circulate 30 seconds before completing.Then system can be by these three watts
Reading is averagely reaching the average power consumption of circulation.The fortune of average power consumption can be set up to each subsequent circulating repetition process
Row, Dynamic Graph.Furthermore it is possible to identical three points to obtaining carry out curve fitting come the equation for obtaining watt to the time.Then,
Curve will be integrated on time frame by people, and divided by time elapse obtaining " true average " power.
By " true average " power for knowing determination described above, system can record " true average " power and send out
Raw exact time.In the example in fig. 4, " true average " power is defined as 20.6 by technique described above
Watt, which occurs on a timeline 1.2.Then, the time (1.2) that calculating " true average " by system occurs is to circulation
The ratio of midpoint times (1.5).In the diagram, the ratio will be 1.2/1.5=80%.Then, in subsequent circulation, system
Simply obtained in the instantaneous power consumption with the 80% consistent time of plan midpoint times to obtain the accurate of " true average "
Approximation.This simplifies the approximation of acquisition " true average " in the power level measurement of special time by only needing one
Process.
Fig. 5 is illustrated for determining that home network self-energy consumes equipment and/or the energy in multiple energy dissipation devices disappears
Another embodiment of the energy/power consumptions profile of the special part of consumption equipment.In this embodiment, system is just being closed
The reading of gauge table is obtained before and after circulation obtaining the power consumption of equipment.For example, multiplier can be determined to exponential delay,
Which can provide the representative of true average and estimate (for example, power during multiplier * loop ends).It is similar to said circumstances,
The algorithm obtains power level (because level is most stable and reaches minimum slope herein) and then by the work(in loop ends
Rate is related to the true average obtained by the method described above for Fig. 4.In this case, true average is calculated with knot
The ratio of tail power consumption.The ratio will be greater than 1, because true average will be greater than the power consumption that ends up.It is then possible in the ending of circulation
Power consumption is read, and is multiplied by multiplier to estimate mean power.This makes it easier to obtain average power consumption.Certainly, the process assumes
Subsequent circulation is similar to the circulation shape so as to calculating ratio or multiplier.Hope is recalibrated by people with certain frequency specified
The ratio is considering the change in curve shape.Curve shape is by by all of shadow in the variable of relatively early general introduction in the disclosure
Ring.May need about to be recalibrated weekly, which calculates the ratio of time reading mean power before being also applied to
Embodiment.
Fig. 6 is illustrated for determining that home network self-energy consumes equipment and/or the energy in multiple energy dissipation devices disappears
Another embodiment of the energy/power consumptions profile of the special part of consumption equipment.Using the data for being measured in circulation in early days
Then point, system can be integrated to determine this to the area under a curve divided by time elapse with curve matching exponential curve
The average integral power consumption of time frame.For example, system can quickly continuous (for example entering 30,60 and 90 seconds of operation circulation) from
Energy meter scale obtains power consumption data two or more times, and then these points of curve matching are obtaining the power curve to the time.
Then system will be integrated to the area under " power consumption is to the time graph ", estimates length of the cycle or long using circulation before
Degree is used as guidance.Such as in situation earlier, system by integral energy (watt-hour) divided by length of the cycle come obtain this when
Average power consumption during frame.
Fig. 7 diagrams are can be applicable to for determining that home network self-energy is consumed in equipment and/or multiple energy dissipation devices
Energy dissipation device special part energy/power consumptions profile property embodiment described above improvement.Consider
In family, other equipment is to open when appliance power level is read, and expects that a kind of mode is come from us from calculation noted herein
The mean power that method is obtained to each electrical equipment deducts " quiescent dissipation " of family.For example, if family has many power supplys, route
