Followingly embodiments of the present invention are described with reference to accompanying drawing.Fig. 1 represents an example of the structure of apparatus for controlling elevator, and this control system is controlled the operation of each elevator in the mode that all the time aggregate power of many elevators is suppressed at below the set upper limit value.
Calculate the aggregate power that is used for each elevator and be suppressed at aggregate power inhibiting value (aggregate power inhibiting value device 205) below the set upper limit value, calculate the power inhibiting value indicator of distribution (the power inhibiting value indicator of distribution computer device 210 of each elevator) that is used for this inhibiting value is distributed to each elevator according to the elevator lobby calling waiting time that each elevator is accepted, calculate 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 the aggregate power inhibiting value.
Fig. 2 represents the structure of 3 elevators, No. 1 elevator is a lift car 11, No. 2 elevators are lift car 12, No. 3 elevators are lift car 13, and information of each lift car (load-carrying or seating capacity and elevator door opening-closing state etc. in the destination floor calling of logining in lift car, the lift car) and the elevator lobby call information of importing by elevator lobby button (41,42,43) (direction, login time) are sent in the composite control apparatus 20.Composite control apparatus 20 is adjusted maximum power by the operation (maximum speed, acceleration/accel, standing time) of each elevator of control.
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 the group manage apparatus, also can be included in other devices.For example, in the building, be provided with many elevators, and these elevators also can be controlled the operation of each elevator by composite control apparatus 20 under the situation of not carrying out group's management control.
In addition, composite control apparatus 20 transmits to each elevator control device (31, No. 2 elevator control device 32 of No. 1 elevator control device and No. 3 elevator control device 33) and is used to move the instruction of control, so that the power of each elevator is regulated.
Below the composite control apparatus 20 of Fig. 1 is elaborated.
Store elevator specification (command speed, acceleration/accel, nominal payload etc.), building specification (floor quantity, floor gap every, elevator platform number etc.) in elevator specification and the building specification data memory storage 201.Savings has the prediction of each floor of arrival of the elevator cage operation data (speed, direction etc.) collected from the elevator lobby of each elevator control device, lift car and each floor, elevator lobby call data, lift car call data, seating capacity data, each lift car to arrive time data and elevator lobby call duration data (calling out the elapsed time that login is started at from elevator lobby) etc. in the operation related data of each elevator savings device 202.
The power change curve computer device 203 of each elevator is 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 the building specification data memory storage, and the current point in time that calculates each elevator is with respect to the power change curve of after this time.The power change curve represents that the time dependent that uses 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 calculates according to the ascent direction of the lift car of current point in time or descent direction, speed, acceleration/accel, seating capacity, elevator lobby is called out and lift car was called out in (not comprising nonevent calling) any information at least.
In aggregate power change curve computer device 204, the power change curve of each elevator is 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 setting device 206) compared, when maximum power value had surpassed threshold value, the magnitude of power of calculating the needs inhibition according to the difference of maximum power value and threshold value was the aggregate power inhibiting value.Threshold value is the higher limit of elevator single-piece maximum power, 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 respectively illustrations 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 is represented magnitude of power, and the unit of magnitude of power is not with W (watt) expression, but the power during with command speed (corresponding with maximum speed) is 100 to have carried out normalized and represent.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 between the two is the aggregate power inhibiting value.When carrying out energy-saving run, inhibiting value 120 is distributed to each elevator, so that the maxim of aggregate power is controlled at below 250.
Followingly the method for calculating of the power change curve of each elevator is described with reference to Fig. 8.
Position according to position, speed, direction and the elevator of the lift car of each elevator constantly that sets out are stopped next time 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 of distance current time or the lift car calling decides.(unit is m/s 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)
2), can calculate the power p (t) of each time point by following formula.
P(t)＝v(t)·[(Mc+Mw+Mp)·α(t)+ΔMu·g]…(1)
In the formula, Mc represents the weight (do not comprise the 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 (comprise between the weight of passenger's the total weight of lift car and 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 according to elevator specification decision, and Mp represents the prediction passenger weight (prediction load carrying ability) of 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.Perhaps, Mp also can be 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 the power P (t) of calculating each time point t, can obtain power change curve shown in Figure 3.
Followingly the existence method of calculating of power change curve during the allocated elevators hall call of response not as yet is described with reference to Fig. 9.
The not situation of the elevator of the allocated elevators hall call of response is accepted as yet in Fig. 9 (a) expression.Among the figure, elevator is positioned at 6 layers, and it travels towards the below, and has accepted the not elevator lobby of the response calling as yet 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 lift car calling of deriving from is called out in expression from the elevator lobby that does not respond as yet a prognostic chart.The lift car calling takes place at 10 layers in prediction among the figure.When deriving from the prediction of lift car calling, can from the statistics in past, select the highest data of probability, also can select end floor (the superiors or orlop) etc.
Fig. 9 (c) expression according to Fig. 9 (b) to the elevator lobby of response is not called out and the lift car that derives from is called out the velocity curve of predicting as yet prediction example.Elevator is started at after 15 seconds from current point in time and is arrived 1 layer, the passenger who does not respond the elevator lobby calling takes advantage of into elevator (berthing time is 10 seconds), start at after having passed through 25 seconds from 1 layer from current point in time, stop after deriving from 10 layers that lift car calls out driving to after 85 seconds.Accelerating curve is the same with Fig. 8 (b) can be obtained according to Fig. 9 (c), and load carrying ability can be according to the statistics in past, for example dope according to the average seating capacity of each floor under this time period or flow of the people etc.Therefore, even under situation, also can pass through the predicted data of computation speed curve and accelerating curve etc., and obtain the predictor of load carrying ability, calculate the power change curve according to formula (1) with the allocated elevators hall call that does not respond as yet.
Followingly distribution method is described with reference to Fig. 1.Service indication (for example wait time) according to each elevator carries out the power inhibition, makes that the service indication of elevator is good more, and the power amount of suppression is big more.
The prediction latency time that the elevator lobby that each elevator of calculating is accepted in the prediction latency time computer device 207 of Fig. 1 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 login floor that the elevator car arrives elevator lobby of service calls out prediction time of advent and calculate.
Seating capacity computer device 208 is according to seating capacity in the lift car of current point in time (load value according to lift car is calculated) or calculate seating capacity in the lift car of each elevator from the prediction seating capacity that the number of the elevator up and down data in past are obtained.The passenger's of each elevator prediction riding time is calculated in the prediction of prediction riding time computer device 209 destination floors according to each elevator car arrives passenger (call out judge by lift car) time of advent.
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 the aggregate power inhibiting value is distributed to each elevator is calculated the power inhibiting value indicator of distribution of each elevator.For example, the prediction latency time of elevator is long more, then sets indicator of distribution (distribution ratio) more little, just dwindles the power inhibiting value.Thus, can make of poor quality to passenger's operation service, be that the long elevator of wait time is compared with other elevators, the degree that the operation that suppresses to carry out by power is adjusted is light, so can prevent separate unit elevator and the whole extreme situation about descending of service quality that takes place of elevator.
The power inhibiting value computer device 211 of each elevator is given each elevator according to power inhibiting value indicator of distribution with the aggregate power inhibiting value, and calculates the power inhibiting value of each elevator.The maximum speed of each elevator or acceleration calculation device are obtained maximum speed, acceleration/accel or the standing time of each elevator when moving control and being energy-saving run according to the power inhibiting value of each elevator of being calculated by the power inhibiting value computer device of each elevator, and send it to each elevator control device.
Fig. 4 is the concrete example when 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 was 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, at No. 1 elevator, according to 1/{50/ (50+5+15) } calculate, obtaining its value is 1.4.The value of calculating No. 2 elevators and No. 3 elevators equally is respectively 14 and 4.7.Then, at the inverse of the ratio of the prediction latency time of each elevator, obtain with respect to its single-piece ratio.For example, at No. 1 elevator, calculate according to 1.4/ (1.4+14+4.7=20.1), obtaining its value is 0.07.The value of calculating No. 2 elevators and No. 3 elevators equally is respectively 0.7 and 0.23, and this value is exactly a power inhibiting value indicator of distribution.When calculating, according to the length according to prediction latency time, the mode that power inhibiting value indicator of distribution is diminished is calculated.
The power inhibiting value of each elevator is calculated by the power division index that the aggregate power inhibiting value be multiply by each elevator respectively, and result calculated is 8,84 and 28 (aggregate value satisfies 120).From No. 1 elevator, its prediction latency time is 50 seconds, and prediction latency time is long, so set the power inhibiting value of No. 1 elevator less, is set at 8, thus, can avoid as much as possible descending because of power suppresses to cause elevator operation service quality.In addition, because the prediction latency time of No. 2 elevators is 5 seconds, prediction latency time is short, thus its power inhibiting value is bigger, be set at 84.
Decide the power inhibiting value of each elevator according to the length of the wait time of each elevator, feasible operation service quality equalization (avoiding the operation service quality to produce overbalance) to the passenger, so on the whole from the passenger, big overbalance can not take place in the operation service quality of each elevator, therefore, even under energy saver mode, also can provide favorable service to the passenger.
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, variation (having changed speed at this) has taken place in the maximum speed of the elevator of each among the figure, the power change curve of each elevator is by 3 graphical representation of the downside of Fig. 5, the aggregate power change curve is by the graphical representation of the top of Fig. 5, and the aggregate power change curve is controlled in below the threshold value all the time.
As mentioned above, owing to obtain the amount of the part of the higher limit that exceeds its aggregate power according to the power change curve of each elevator, and this plussage distributed to each elevator as the power inhibiting value, by maximum speed, acceleration/accel or the standing time of each elevator are adjusted to carry out energy-saving run (running), thus, the aggregate power of many elevators at each time point can be suppressed at below the specified value effectively, thereby can realize energy-conservationization of elevator device.
In addition, owing to can distribute plussage according to the operation service situation of each such elevator of wait time shown in Figure 4, so can be when limiting the power of each elevator, the influence that the passenger to each elevator of each time point is brought is controlled at suitable state (overbalance that can suppress the operation service quality).
In addition, in Fig. 1, coming the occasion of horsepower rating inhibiting value indicator of distribution with the combination according to prediction latency time, seating capacity and prediction riding time is that example is described, but as long as at least a information in these information of use just can obtain same effect.
For example, according to prediction latency time horsepower rating inhibiting value indicator of distribution the time, because wait time is the service indication that the passenger payes attention to the most, so, by deciding indicator of distribution, can under the situation that suppresses service overbalance (discontented degree is less), realize the power adjustment according to wait time.
On the other hand, according to seating capacity horsepower rating inhibiting value indicator of distribution the time, owing to decide power inhibiting value indicator of distribution, so can be when power is adjusted most of people's service quality be controlled in the suitable scope according to the number that is subjected to power adjustment influence.
When coming horsepower rating inhibiting value indicator of distribution according to the prediction riding time, can know from the power change curve of No. 2 elevators of Fig. 4 and Fig. 5, when carrying out the power adjustment, maximum speed is because of after the power adjustment is restricted, riding time is elongated, so,, can aspect the easiest affected riding time, service quality be controlled in the suitable scope by the power adjustment.
And, also can be by any information in prediction latency time, seating capacity and the prediction riding time being made up (for example prediction latency time and seating capacity), make it possible in more detail service quality be estimated, so, can when power is adjusted, the service quality that makes up be controlled in the suitable scope.In addition, use the prediction that elevator lobby is called out to replace prediction latency time also can access same effect the time of advent.
Below energy-conservationization that realizes by the aggregate power that suppresses many elevators carried out supplemental instruction.When the total resistance value of supposing the resistance of the power line of building power receiving equipment and voltage transformer etc. was Rt, the loss that is caused by the resistance of power line and voltage transformer etc. was with Rti
2Expression.Current effective value when the i in the formula represents elevator work.
It is 70% o'clock that i is suppressed, Rti
2Be 50%, loss reduces half.In fact, because the speed reduction, so work-hours T is elongated, but because T and i roughly are inverse ratio, so, be 70% o'clock in that i is suppressed, 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 that causes by the electric wire of building power receiving equipment and voltage transformer etc., thereby can realize energy-conservationization of total system.And,,,, can contribute to energy-conservationization so can under the good condition of service of generating efficiency, move owing to can suppress the fluctuation of electric energy generated from the generating set side of electric system side.
Fig. 6 represents the structure with many corresponding power receiving equipments of elevator device.Powered by the total current-collecting device A01 of elevator of electricity from building single-piece power receiving equipment to being responsible for all elevators, further power 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 to the current-collecting device (No. 1 elevator A02, No. 2 elevator A04, No. 3 elevator A06) of each elevator.When adopting the embodiment of apparatus for controlling elevator shown in Figure 1, the aggregate power of all elevators can be suppressed at below the specified value all the time, so can suppress the power capability of the total current-collecting device of elevator.For example, be example with Fig. 3 and Fig. 5, when 3 elevators having taken place start this worst situation simultaneously, the total current-collecting device of elevator needs 450 power capability, still, and as shown in Figure 5, because this power capability can be suppressed all the time is 250, 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 the electric system side, along with the increase in these buildings, load fluctuation diminishes, CO
2The utilization of the base load that quantity discharged is low (base load) generator becomes more convenient.
Fig. 7 is corresponding with Fig. 1, when threshold setting device 206 carries out threshold setting, according to the signal sets suitable threshold from building gross horsepower management devices 300.
300 pairs of buildings of gross horsepower management devices, building single-piece gross horsepower manages, and makes gross horsepower not overshoot all the time value.For example, in the afternoon 1 o'clock to 2 o'clock of 1 day peak of power consumption, time period in peak of power consumption is detected building single-piece gross horsepower, calculate according to this detected value gross horsepower is controlled at elevator single-piece power threshold below the specified value, and this power threshold is sent to threshold setting device 206, implement the power adjustment with this, the power of each elevator is controlled at below the threshold value, avoid simultaneously passenger's service quality is descended.
Its result, because the gross horsepower in building is all the time below specified value, thus can reduce the capacity of building single-piece power receiving equipment, 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 contribute to preventing environmental problems such as global warming.
Figure 10 is corresponding with Fig. 1, is provided with regenerating power value calculation apparatus 215 and the elevator regenerated operation of standby (regenerative operation) command device 216 that standby elevator detecting device 213, standby elevator utilize judgment means 214, standby elevator in Figure 10.
Standby elevator detecting device 213 detects from each elevator and does not does not accept the standby elevator that is in readiness for action (halted state) that elevator lobby is called out and lift car is called out.When aggregate power inhibiting value computer device 205 must be suppressed at aggregate power specified value when following because of the aggregate power change curve more than threshold value, if having the standby elevator, then the standby elevator utilizes judgment means 214 to make the judgement that utilizes the standby elevator.
The regenerating power value calculation apparatus 215 of standby elevator calculates qualified standby elevator is driven regenerating power value when regenerating operation.The regenerating power value is by calculating the power change curve, as the maxim of the regenerating power of qualified time period or regenerating power and obtained.When having many qualified standby elevators, calculate the regenerating power value separately of many elevators respectively.
The regenerating power value that calculates is input to the power inhibiting value computer device 211 of each elevator.The power inhibiting value computer device 211 of each elevator will deduct regenerating power (being its aggregate value when having many standby elevators) value that obtains that is produced by the operation of standby elevator from the aggregate power inhibiting value and calculate the power inhibiting value of each elevator as new aggregate power inhibiting value.The elevator regenerated operating instruction device 216 of standby is when the standby elevator utilizes judgment means 214 to be judged as to utilize the standby elevator, transmit the travel direction of lift car and the instruction of speed to control setup, thereby make the qualified elevator that is in readiness for action implement the regeneration operation.
In Fig. 1 and system shown in Figure 7, when the aggregate power change curve of each elevator has surpassed specified value, only the speed or the acceleration/accel adjustment of each elevator are come power controlling, make the aggregate power change curve below specified value, and in system shown in Figure 10, owing to utilize the operation of regenerating of standby elevator, so can under the situation of the service quality that does not influence each elevator, reduce aggregate power.And, when elevator is regenerated operation, generate electricity owing to electrical motor becomes electrical generator, so can reduce elevator single-piece consumed power.Because the standby elevator is in no load condition (load carrying ability is zero), therefore, make lift car when the rising direction is moved, form the regeneration running state.
