Calculate for the aggregate power of each elevator being suppressed to the aggregate power inhibiting value (aggregate power inhibiting value device 205) below set upper limit value, the wait time that the elevator lobby of accepting according to each elevator is called out calculates the power inhibiting value indicator of distribution (the power inhibiting value indicator of distribution computer device 210 of each elevator) for this inhibiting value being distributed to each elevator, calculates the power inhibiting value (the power inhibiting value computer device 211 of each elevator) of each elevator according to power inhibiting value indicator of distribution from aggregate power inhibiting value.
Fig. 2 represents the structure of 3 elevators, No. 1 elevator is lift car 11, No. 2 elevators are lift car 12, No. 3 elevators are lift car 13, and the information of each lift car (destination floor of logining in lift car is called out, lift car in load-carrying or seating capacity and elevator door opening-closing state etc.) and the elevator lobby call information (direction, login time) of inputting by elevator lobby button (41,42,43) are sent in composite control apparatus 20.Composite control apparatus 20 is adjusted maximum power by the operation (maximum speed, acceleration/accel, standing time) of controlling each elevator.
Group manage apparatus carries out Comprehensive Control to the operation of many elevators, and the composite control apparatus 20 of Fig. 2 can be included in group manage apparatus, also can be included in other devices.For example, in building, be provided with many elevators, and these elevators are not in the situation that carrying out group's management control, also can control by composite control apparatus 20 operation of each elevator.
In addition, composite control apparatus 20 transmits for moving the instruction of control, to the power of each elevator is regulated to the control setup (control setups 33 of 32 and No. 3 elevators of control setup of 31, No. 2 elevators of control setup of No. 1 elevator) of each elevator.
Below the composite control apparatus 20 of Fig. 1 is elaborated.
In elevator specification and building specification data memory storage 201, store elevator specification (command speed, acceleration/accel, nominal payload etc.), building specification (floor quantity, floor gap every, elevator number of units etc.).In the operation related data savings device 202 of each elevator, accumulate from the control setup of each elevator, elevator cage operation data (the speed of collecting in the elevator lobby of lift car and each floor, direction etc.), elevator lobby call data, lift car call data, seating capacity data, the prediction of the each floor of arrival of each lift car arrives time data and elevator lobby call duration data (calling out the elapsed time that login is started at from elevator lobby) etc.
The power change curve computer device 203 of each elevator, according to the data and the data of savings in the operation related data savings device of each elevator that are stored in elevator specification and building specification data memory storage, calculates the current point in time of each elevator with respect to the power change curve of time after this.Power change curve represents that the time dependent of the use magnitude of power (unit is W) of elevator changes, and figure 3 illustrates the concrete example of power change curve.
The later power change curve of current point in time at least calculates according to any information in the ascent direction of the lift car of current point in time or descent direction, speed, acceleration/accel, seating capacity, elevator lobby calling and lift car calling (not comprising nonevent calling).
In aggregate power change curve computer device 204, the power change curve of each elevator added up to and calculate aggregate power change curve (gross horsepower change curve).
Aggregate power inhibiting value computer device 205 detects the maximum power value of aggregate power change curve, and itself and threshold value (being set by Threshold device 206) are compared, in the time that maximum power value has exceeded threshold value, needing according to the poor calculating of maximum power value and threshold value the magnitude of power suppressing is aggregate power inhibiting value.Threshold value is the higher limit of the maximum power of elevator entirety, and it is for example set according to the power capability of the power receiving equipment of all elevators.
3 diagram of curves of the downside of Fig. 3 are respectively exemplified with the power change curve of No. 1 elevator, No. 2 elevators and No. 3 elevators.Shown in these figure is the power change curve in 60 seconds futures.The longitudinal axis represents magnitude of power, and the unit of magnitude of power represents with W (watt), but power during taking command speed (corresponding with maximum speed) has carried out normalized and represents as 100.The aggregate power change curve of 3 elevators of graphical representation of the top of Fig. 3, with respect to the upper limit threshold 250 of power, maximum power is 370, is 120 so difference is between the two aggregate power inhibiting value.In the time carrying out energy-saving run, inhibiting value 120 is distributed to each elevator so that by the Maximum constraint of aggregate power below 250.
The method of calculating of the power change curve referring to Fig. 8 to each elevator describes.
The position of next time stopping according to position, speed, direction and the elevator of the lift car of each the elevator in the moment of setting out, generates curve (Fig. 8 (a)) and accelerating curve (Fig. 8 (b)) that elevator drives to the moving velocity of stop position.
The next stop position of elevator calls out according to the nearest elevator lobby of the elevator position apart from current time or lift car calling decides.According to the speed v (t) (unit is m/s) of each time point t that can know from velocity curve and accelerating curve and acceleration alpha (t), (unit is m/s
2), can calculate by following formula the power p (t) of each time point.
P(t)＝v(t)·[(Mc+Mw+Mp)·α(t)+ΔMu·g]…(1)
In formula, Mc represents the weight (do not comprise passenger, unit is kg) of lift car,
Mw represents the weight of counterbalanced weight,
Mp represents passenger's total weight (load carrying ability),
Δ Mu represents overbalance weight (between the total weight of the lift car including passenger and the weight of counterbalanced weight poor),
G represents acceleration due to gravity (9.8m/s
2).
Overbalance weight Δ Mu can obtain according to Δ Mu=(Mc+Mp)-Mw.Mc, Mw represent the constant value determining according to elevator specification, and Mp represents the prediction passenger weight (prediction load carrying ability) calculating according to the load measuring sensor value (load carrying ability) of lift car or the prediction seating capacity that can go out from the flow of the people information prediction in building.Or Mp can be also according to seating capacity or predict the load carrying ability that seating capacity is calculated by the product of seating capacity and average weight.The unit of power P (t) obtains according to formula (1), is kgm
2/ s
3=Nm/s=J/s=W.By calculating the power P (t) of each time point t, can obtain the power change curve shown in Fig. 3.
The method of calculating of the power change curve while the allocated elevators hall call that existence not yet responds being described referring to Fig. 9.
Fig. 9 (a) represents to accept the not yet situation of the elevator of the allocated elevators hall call of response.In figure, elevator is positioned at 6 layers, and it travels towards below, and has accepted the elevator lobby not yet the responding calling at the ascent direction of 1 layer of generation.Be 15 seconds prediction time of advent that arrives 1 layer.Fig. 9 (b) is the prognostic chart that represents to call out from the elevator lobby of not yet response the lift car calling of deriving from.In figure there is lift car calling at 10 layers in prediction.In the time deriving from the prediction of lift car calling, can from the statistics in past, select the data that probability is the highest, also can select end floor (the superiors or orlop) etc.
Fig. 9 (c) represents the pre-test case of the lift car of the elevator lobby calling not yet responding and derivation being called out to the velocity curve of predicting according to Fig. 9 (b).Elevator is started at and 15 seconds, is arrived 1 layer from current point in time, the passenger who does not respond elevator lobby calling takes advantage of into elevator (berthing time is 10 seconds), from current point in time start at through after 25 seconds from 1 layer, after 85 seconds, drive to derive from lift car call out 10 layers after stop.Accelerating curve is the same with Fig. 8 (b) can be obtained according to Fig. 9 (c), and load carrying ability can for example, dope according to the average seating capacity of the statistics in past, each floor of basis under this time period or flow of the people etc.Therefore, even in the case of thering is the allocated elevators hall call of not yet response, also can pass through the predicted data of computation speed curve and accelerating curve etc., and obtain the predictor of load carrying ability, calculate power change curve according to formula (1).
Referring to Fig. 1, distribution method is described.For example, carry out power inhibition according to the service indication of each elevator (wait time), make the service indication of elevator better, power amount of suppression is larger.
In the prediction latency time computer device 207 of Fig. 1, calculate the prediction latency time that elevator lobby that each elevator accept is called out.Prediction latency time start at institute's elapsed time according to the login time point of calling out from elevator lobby and provide the login floor that the elevator car arrives elevator lobby of service calls out prediction time of advent and calculate.
The prediction seating capacity that seating capacity computer device 208 is obtained according to seating capacity in the lift car of current point in time (calculating according to the load value of lift car) or from the number of the elevator up and down data in past is calculated seating capacity in the lift car of each elevator.Prediction riding time computer device 209 calculates the passenger's of each elevator prediction riding time the time of advent according to the prediction of each elevator car arrives passenger's destination floor (calling out to judge by lift car).
The power inhibiting value indicator of distribution computer device 210 of each elevator is at least according to any information in the prediction riding time of the seating capacity of the prediction latency time of each elevator, each elevator, each elevator, distribution ratio indicator of distribution when aggregate power inhibiting value is distributed to each elevator, calculates the power inhibiting value indicator of distribution of each elevator.For example, the prediction latency time of elevator is longer, indicator of distribution (distribution ratio) is set littlely, namely dwindles power inhibiting value.Thus, can make elevator of poor quality to passenger's operation service, i.e. wait time length compared with other elevators, the mild degree that the operation that suppresses to carry out by power is adjusted, so can prevent that separate unit elevator and elevator entirety from the extreme situation about declining of service quality occurring.
The power inhibiting value computer device 211 of each elevator is given each elevator according to power inhibiting value indicator of distribution by aggregate power inhibiting value, and calculates the power inhibiting value of each elevator.The power inhibiting value of each the elevator that the maximum speed of each elevator or acceleration calculation device basis are calculated by the power inhibiting value computer device of each elevator is obtained and is moved maximum speed, acceleration/accel or the standing time of controlling each elevator while being energy-saving run, and sends it to the control setup of each elevator.
Fig. 4 is the concrete example while representing according to prediction latency time horsepower rating inhibiting value indicator of distribution.The table of Fig. 4 is set according to the situation of Fig. 3, and its aggregate power inhibiting value is 120.Therefore, according to prediction latency time, aggregate power inhibiting value 120 is distributed to these 3 elevators of elevator to 3 elevator No. 1.The prediction latency time of No. 1 elevator, No. 2 elevators and No. 3 elevators is respectively 50 seconds, 5 seconds and 15 seconds.
Calculate the inverse of the ratio (with respect to the ratio of aggregate value) of the prediction latency time of each elevator.For example, for No. 1 elevator, according to 1/{50/ (50+5+15) } calculate, obtaining its value is 1.4.The value that calculates equally No. 2 elevators and No. 3 elevators is respectively 14 and 4.7.Then,, for the inverse of the ratio of the prediction latency time of each elevator, obtain with respect to its overall ratio.For example, for No. 1 elevator, calculate according to 1.4/ (1.4+14+4.7=20.1), obtaining its value is 0.07.The value that calculates equally No. 2 elevators and No. 3 elevators is respectively 0.7 and 0.23, and this value is exactly power inhibiting value indicator of distribution.In the time calculating, according to according to the length of prediction latency time, the mode that power inhibiting value indicator of distribution is diminished is calculated.
The power inhibiting value of each elevator calculates by the power division index that aggregate power inhibiting value is multiplied by each elevator respectively, and the result of calculating is 8,84 and 28 (aggregate value meets 120).From No. 1 elevator, its prediction latency time is 50 seconds, and prediction latency time is long, so the power inhibiting value of No. 1 elevator is set littlely, is set as 8, thus, can avoid as much as possible suppressing to cause elevator operation service Quality Down because of power.In addition, because the prediction latency time of No. 2 elevators is 5 seconds, prediction latency time is short, so by larger its power inhibiting value, be set as 84.
Decide the power inhibiting value of each elevator according to the length of the wait time of each elevator, make the operation service quality equalization (avoiding operation service mass formation overbalance) to passenger, so from passenger on the whole, can there is not large overbalance in the operation service quality of each elevator, therefore, even also can provide good service to passenger under energy saver mode.
The power change curve of Fig. 5 generates according to Fig. 4, it represents the power change curve of each elevator after the power inhibiting value of each elevator is determined, there is variation (having changed speed at this) in the maximum speed of each elevator in figure, the power change curve of each elevator is by 3 graphical representation of the downside of Fig. 5, aggregate power change curve is by the graphical representation of the top of Fig. 5, and aggregate power change curve is controlled in below threshold value all the time.
As mentioned above, owing to obtaining the amount of the part of the higher limit that exceeds its aggregate power according to the power change curve of each elevator, and distribute to each elevator using this plussage as power inhibiting value, carry out energy-saving run (running) by the maximum speed to each elevator, acceleration/accel or standing time adjustment, thus, many elevators can be suppressed at below specified value effectively in the aggregate power of each time point, thereby can realize the energy-saving of elevator device.
In addition, owing to distributing plussage according to the operation service situation of each such elevator of the wait time shown in Fig. 4, so can be in the power of each elevator of restriction, the impact that the passenger on each elevator of each time point is brought is controlled at suitable state (can suppress the overbalance of operation service quality).
In addition, in Fig. 1, be described as an example of the occasion of carrying out horsepower rating inhibiting value indicator of distribution according to the combination of prediction latency time, seating capacity and prediction riding time example, but as long as use at least one information in these information, just can obtain same effect.
For example, when according to prediction latency time horsepower rating inhibiting value indicator of distribution, because wait time is the service indication that passenger payes attention to the most, so, by deciding indicator of distribution according to wait time, can service overbalance (discontented degree is less), realize power adjustment in the case of suppressing.
On the other hand, when according to seating capacity horsepower rating inhibiting value indicator of distribution, owing to deciding power inhibiting value indicator of distribution according to the number that is subject to power adjustment impact, so can the service quality of most people be controlled in suitable scope in the time that power is adjusted.
In the time carrying out horsepower rating inhibiting value indicator of distribution according to prediction riding time, can know from the power change curve of No. 2 elevators of Fig. 4 and Fig. 5, in the time carrying out power adjustment, maximum speed is because of after power adjustment is restricted, riding time is elongated, so, adjust by power, can aspect the easiest affected riding time, service quality be controlled in suitable scope.
And, also can for example, by any information in prediction latency time, seating capacity and prediction riding time be combined to (prediction latency time and seating capacity), make it possible in more detail service quality be evaluated, so, can in the time that power is adjusted, the service quality of combination be controlled in suitable scope.In addition, use the prediction that elevator lobby is called out to replace prediction latency time also can obtain same effect the time of advent.
Below the energy-saving of realizing by the aggregate power that suppresses many elevators is carried out to supplemental instruction.When the total resistance value of supposing the resistance of power line and the voltage transformer etc. of building power receiving equipment is Rt, the loss being caused by the resistance of power line and voltage transformer etc. is with Rti
2represent.Current effective value when i in formula represents elevator work.
When i is suppressed to be 70%, Rti
2be 50%, loss reduces half.In fact, due to Speed Reduction, so work-hours T is elongated, but because T and i are roughly inverse ratio, so, in the time that i is suppressed to be 70%, can will consider the loss amount Rti of time factor
2t is reduced to 70%.
So, by suppressing aggregate power, can also reduce the loss being caused by electric wire and the voltage transformer etc. of building power receiving equipment, thereby can realize the energy-saving of whole system.And, from the generating set side of electric system side, owing to can suppressing the fluctuation of electric energy generated, so can move under the good condition of service of generating efficiency, can contribute to energy-saving.
Fig. 6 represents the structure with many corresponding power receiving equipments of elevator device.From the power receiving equipment of Whole Building to the total current-collecting device A01 power supply of the responsible powered elevator of all elevators, further power to the current-collecting device (No. 1 elevator A02, No. 2 elevator A04, No. 3 elevator A06) of each elevator by the total current-collecting device A01 of this elevator, and finally power to the actuating device (No. 1 elevator A03, No. 2 elevator A05, No. 3 elevator A07) of each elevator.While adopting the embodiment of the apparatus for controlling elevator shown in Fig. 1, the aggregate power of all elevators can be suppressed at below specified value all the time, so can suppress the power capability of the total current-collecting device of elevator.For example,, taking Fig. 3 and Fig. 5 as example, in the time 3 elevators have occurred starting this worst situation simultaneously, the total current-collecting device of elevator needs 450 power capability, still, and as shown in Figure 5, be 250 owing to this power capability can being suppressed all the time, so power capability can be reduced to 55%.Its result, can reduce the cost of power receiving equipment, saves the required space of power receiving equipment, and can make the further equalization of power, thereby can reduce the contract power in building.In addition, from electric system side, along with the increase in these buildings, load fluctuation diminishes, CO
2the utilization of base load (base load) generator that quantity discharged is low becomes more convenient.
Fig. 7 is corresponding with Fig. 1, in the time that Threshold device 206 carries out Threshold, according to the suitable threshold value of signal sets from building gross horsepower management devices 300.
Building gross horsepower management devices 300 manages the gross horsepower of Whole Building, makes gross horsepower not exceed all the time specified value.For example, in the afternoon 1 o'clock to 2 o'clock of the peak of power consumption of 1 day, detect the gross horsepower of Whole Building in the time period of peak of power consumption, calculate the power threshold that gross horsepower is controlled to the elevator entirety below specified value according to this detected value, and this power threshold is sent to Threshold device 206, implement power adjustment with this, the power of each elevator is controlled at below threshold value, avoid passenger's service quality to decline simultaneously.
Its result, because the gross horsepower in building is all the time below specified value, thus can reduce the capacity of the power receiving equipment of Whole Building, and can reduce contract power.In addition, along with the increase in these buildings, load fluctuation diminishes, CO
2the utilization of the base load generator that quantity discharged is low becomes more convenient, thereby can also be to preventing that the environmental problems such as global warming from contributing.
Figure 10 is corresponding with Fig. 1, is provided with standby elevator detecting device 213, standby elevator and utilizes regenerating power value calculation apparatus 215 and the elevator regenerated operation of standby (regenerative operation) command device 216 of judgment means 214, standby elevator in Figure 10.
Standby elevator detecting device 213 detects and does not does not accept the standby elevator in readiness for action (halted state) that elevator lobby is called out and lift car is called out from each elevator.In the time that aggregate power inhibiting value computer device 205 must be suppressed at below specified value because of aggregate power change curve by aggregate power more than threshold value, if having standby elevator, standby elevator utilizes judgment means 214 to make the judgement that utilizes standby elevator.
The regenerating power value calculation apparatus 215 of standby elevator calculates regenerating power value when qualified standby elevator is driven to regenerate operation.Regenerating power value is by calculating power change curve, as the regenerating power of qualified time period or the maxim of regenerating power and obtained.In the time thering is many qualified standby elevators, calculate respectively the regenerating power value separately of many elevators.
The regenerating power value calculating is input to the power inhibiting value computer device 211 of each elevator.The power inhibiting value computer device 211 of each elevator calculates the power inhibiting value of each elevator using deduct value that the regenerating power (being its aggregate value while having many standby elevators) that produced by the operation of standby elevator obtains from aggregate power inhibiting value as new aggregate power inhibiting value.The elevator regenerated operating instruction device 216 of standby is in the time that standby elevator utilizes judgment means 214 to be judged as to utilize standby elevator, transmit the travel direction of lift car and the instruction of speed to control setup, thereby make the qualified elevator in readiness for action implement regeneration operation.
In the system shown in Fig. 1 and Fig. 7, in the time that the aggregate power change curve of each elevator has exceeded specified value, only speed or the acceleration/accel adjustment to each elevator carried out power ratio control, make aggregate power change curve below specified value, and in the system shown in Figure 10, owing to utilizing the operation of regenerating of standby elevator, so can reduce aggregate power in the case of not affecting the service quality of each elevator.And, in the time that elevator is regenerated operation, generate electricity because electrical motor becomes electrical generator, so can reduce the consumed power of elevator entirety.Because standby elevator is in no load condition (load carrying ability is zero), therefore, in the time that being moved towards ascent direction, lift car forms regeneration running state.
