Abstract

PROBLEM TO BE SOLVED: To provide a group management control device of an elevator which can suitably perform unit allocation by using adaptability call allocation even in a time zone in which a larger number of users are concentrated to a specified floor, and a group management control method.SOLUTION: A group management control device acquires a standby time addition value (C2×penalty(i)) which becomes large as a delay time (t)i is long, and as an average number n of passengers becomes large on the basis of the delay time (t)i of the arrival of a unit to a specified floor when a novel estimation floor call is allocated about each unit and the average number n of passengers in the specified floor based on past learning results. The group management control device uses a value which is obtained by adding the standby time addition value to a value which is obtained by subtracting a total value WT(i) of a standby time at non-allocation from a total value NWT(i) of a standby time when the novel destination call is allocated to the unit as one parameter of an evaluation value COST(i) of the unit. The group management control device also allocates the novel destination floor call to a unit which is the smallest in the evaluation value.SELECTED DRAWING: Figure 4

  The adaptive call assignment (ACA) described above has the effect that good transport performance can be obtained with a relatively simple algorithm. However, in a time zone in which many users are concentrated on the lobby floor, for example, at work hours, appropriate evaluation cannot be performed and passengers on the lobby floor may not be carried.

  The present invention relates to an elevator group management control apparatus and a group management control method capable of appropriately performing unit allocation using adaptive call allocation (ACA) even in a time zone where many users are concentrated on a specific floor. I will provide a.

The elevator group management control device of the present invention assigns a new destination floor call to any one of a plurality of elevators.

About each unit
When a new destination floor call is assigned to the relevant unit, the first waiting time until the user associated with each destination floor call assigned to the relevant unit can board the relevant unit Total waiting time and
The second value that is the total waiting time until a user associated with each destination floor call assigned to the relevant unit can board the relevant unit when no new destination floor call is assigned to the relevant unit. Total waiting time and
Based on the delay time of arrival at the specific floor of the unit when the new destination floor call is assigned to the unit and the average number of passengers on the specific floor based on past learning results, the longer the delay time, The waiting time addition value, which becomes larger as the average number of passengers increases,
Further, a value obtained by adding the waiting time addition value to a value obtained by subtracting the second waiting time total value from the first waiting time total value is obtained.
This added value is used as one parameter of the evaluation value related to allocation in the relevant machine.

  According to the present invention, when obtaining an evaluation value related to allocation based on ACA, the longer the delay time of arrival at a specific floor when a new destination floor call is allocated, the more the average number of passengers on the specific floor Use a waiting time addition value that is a large value. Therefore, the waiting time of passengers expected to occur in a specific floor in the future is reflected in the allocation. Therefore, even in a time zone where many users are concentrated on a specific floor, it is possible to appropriately perform unit allocation using adaptive call allocation (ACA).

(Background of the Invention)
In an elevator group management system provided with a destination floor registration device, an allocation control algorithm called ACA (Adaptive Call Allocation) is often used. In ACA, the total waiting time increment for all passengers when a newly registered destination floor call is assigned to each unit is obtained by the following equation, and the new unit is evaluated to have the smallest increase in total waiting time. Assign a destination floor call.
Change in waiting time = NWT (i) −WT (i)
Here, NWT (i) is the i in the case where a new destination floor call is assigned to the i-th unit in addition to the assigned destination floor call, that is, in the case of responding to the new destination floor call in addition to the assigned destination floor call. The total waiting time of the car No. WT (i) is the sum of the waiting time of the car No. i when a new destination floor call is not assigned to the car i, that is, when only the assigned destination floor call is answered.

  In ACA, the increment of the service completion time (the time from the current time until the user can get off at the destination floor) is evaluated and assigned, or the weighted sum of the waiting time increment and the service completion time increment. May be evaluated and assigned.

  However, in any of the methods, only the service for passengers who have already arrived at the landing is evaluated, and the passengers generated in the future have not been evaluated. Even with such an allocation method, there is no particular problem if the traffic volume is relatively small. However, as the traffic volume increases, the elevator service to passengers may deteriorate. For example, a large number of passengers concentrate on the lobby floor in a short time during office work hours. In such a situation, when a new call is assigned without considering passengers that will occur in the future, the arrival of the elevator to the lobby floor tends to be delayed and the average waiting time tends to increase. In addition, there was a case where passengers on the lobby floor could not be carried due to the late arrival of the elevator.

  Therefore, in the present invention, on the basis of the above knowledge, passengers on the lobby floor that have not occurred yet at the time of determination of the assigned unit but have occurred when returning to the lobby floor, that is, passengers on the lobby floor that will occur in the future In consideration of the above, control is performed to assign a new destination floor call to any one of the elevators. Hereinafter, embodiments of the present invention will be described in detail.

2. Operation 2-1. Outline of Operation An outline of the operation of the elevator group management system according to the present embodiment will be described. In this system, the destination floor registration device 20 accepts registration of the user's destination floor. When registration is accepted by the destination floor registration device 20, the group management control device 10 assigns the registered destination floor to any one of the elevators 40-1 to 40-3. Further, the elevator control device 30 controls the operation of the assigned car assigned the registered destination floor so that the registered floor where the destination floor is registered and the registered destination floor are operated in order. In addition, the destination floor registration device 20 that has received the registration acquires information on the number assigned to the destination floor, and displays the assigned number assigned to the destination floor.

  When the registration of the user's destination floor is accepted by the destination floor registration device 20, the present system displays the assigned number machine and controls the operation of the assigned number machine.

2-2. Operation of Group Management Control Device The operation of the group management control device 10 will be described.

  The group management control device 10 performs an elevator assignment process. The elevator assignment process is a process of assigning the destination floor registered by the destination floor registration device 20 to any one of the elevators 40-1 to 40-3. Specifically, when receiving an allocation request signal from the destination floor registration device 20 via the input / output interface 13, the control unit 11 starts an elevator allocation process. This assignment request signal is a signal that requests the destination floor registered by the destination floor registration device 20 to be assigned to any one of the elevators 40-1 to 40-3. The allocation request signal includes destination floor information indicating the destination floor registered by the user, departure floor information indicating the floor (departure floor) where the destination floor is registered, and the destination floor where the destination floor is registered. And identification information for identifying the registration device 20. The control unit 11 assigns the destination floor indicated by the received assignment request signal to one of the elevators 40-1 to 40-3.

  Specifically, the control part 11 calculates the evaluation value regarding the allocation for selecting the elevator (assignment number machine) which should assign a destination floor first for every elevator based on the operation information of each elevator. Here, the operation information of each elevator includes, for example, the car state of each elevator (including car position, traveling direction, door open / closed state, load, etc.), predicted waiting time, predicted service completion time, and the like. Contains information to indicate. Furthermore, in this embodiment, as will be described later, the operation information of each elevator includes a delay time to the lobby floor due to allocation and an average number of passengers on the lobby floor. After calculating the evaluation value, the control unit 11 selects the elevator having the smallest evaluation value from the elevators 40-1 to 40-3, and assigns the destination floor to the selected elevator.

  Based on the result of the above allocation process, the control unit 11 outputs to the elevator control device 30 a control signal that instructs to operate the registered floor where the destination floor is registered and the registered destination floor in order. The control unit 11 also transmits, as a response to the allocation request signal, allocation machine information indicating the allocation machine to the destination floor registration apparatus 20 in which the destination floor is registered via the input / output interface 13.

2-3. Operation of Destination Floor Registration Device The destination floor registration device 20 receives a destination floor registration operation by a user in the operation unit. The control unit of the destination floor registration device 20 includes destination floor information indicating the destination floor registered by the user, departure floor information indicating the installation floor of the destination floor registration device 20 on which the operation for registering the destination floor is performed, and Then, an allocation request signal including identification information for identifying the destination floor registration device 20 is generated. The control unit of the destination floor registration device 20 outputs the generated assignment request signal to the group management control device 10.

  Moreover, the control part of the destination floor registration apparatus 20 receives the allocation number machine information which shows an allocation number machine from the group management control apparatus 10 as a response of the above-mentioned allocation request signal. The control unit of the destination floor registration device 20 causes the display unit to display the destination floor registered by the user and the information indicating the assigned number machine indicated by the assigned number machine information. As a result, the destination floor registration device 20 notifies the user that the registered destination floor is assigned to the displayed assigned number.

2-4. Specific Operation of Group Management Control Device The group management control device 10 of this embodiment employs an adaptive call allocation (ACA) algorithm as an algorithm for determining an assigned machine number. In this case, in the present embodiment, a parameter (penalty value) based on the delay time of arrival at the lobby floor is employed as a parameter (penalty value) for obtaining an evaluation value related to allocation in ACA.

  An assigned number machine determination process performed by the elevator group management control apparatus 10 according to the first embodiment will be described. FIG. 3 is a flowchart illustrating a flow of assigned number machine determination processing performed by the elevator group management control apparatus 10 according to the first embodiment.

  The group management control device 10 determines whether the car of any one of the plurality of elevators has left the lobby floor (S11). The determination of whether or not the vehicle has departed can be made, for example, by detecting that the car 41 stopped on the first floor has started acceleration.

  When it is determined that the car of any unit has left the lobby floor (YES in S11), the group management control device 10 measures the number of passengers of the departing unit and stores it in the storage unit 12 (S12). The number of passengers can be estimated based on load detection in the car, or can be obtained from the assigned number of destination floor calls for each car.

  The group management control device 10 deletes the measured number of passengers exceeding the predetermined number from the storage unit 12 in order from the oldest (S13). As a result, only the latest predetermined number of passenger measurement values are stored in the storage unit 12.

  An assigned number machine determination process performed by the elevator group management control apparatus 10 according to the first embodiment will be described. FIG. 4 is a flowchart illustrating a flow of assigned number machine determination processing performed by the elevator group management control apparatus 10 according to the first embodiment.

  The group management control device 10 determines whether or not a new destination floor call has been registered (S21). Specifically, when the group management control device 10 receives an allocation request signal for a new destination floor call from the destination floor registration device 20, if any elevator can service the destination floor call, the group management control device 10 It is determined that the destination floor call has been registered.

  When it is determined that the new destination floor call is not registered (NO in S21), the group management control device 10 ends the process according to this flowchart.

  On the other hand, when a new destination floor call is registered (YES in S21), the group management control device 10 calculates the average number of passengers n at the time of departure from the lobby floor based on the stored number of passengers at the time of departure from the lobby floor. Obtain (S22). Specifically, the group management control device 10 reads the latest predetermined number of passenger measurement values stored in the storage unit 12, obtains the average value of all the read passenger measurement values, and obtains this average passenger number Let n. The predetermined number is, for example, ten. As a result, it is possible to appropriately respond to a sudden increase in traffic volume such as working hours in office buildings.

  The group management control device 10 sets 1 as the car number i (S23). In addition, since the car 41 and the number machine correspond one-to-one, the car number i is also the number of the number machine. In the present embodiment, since three elevators 40 are provided, i is 1 to 3.

  The group management control device 10 calculates a total waiting time value WT (i) for all destination floor calls assigned to the i-th car (S24). Here, the waiting time in the i-th car is the time required for the car of the i-th car to arrive at the destination floor call generation floor from the current position (current time). That is, it is the time at which the user associated with the destination floor call waits for the arrival of the i-th machine at the destination floor call generation floor.

  Specifically, the group management control device 10 obtains a waiting time for all destination floor calls assigned to the i-th car with reference to the predicted i-th waiting time table of the i-th car. Then, the group management control device 10 calculates the total waiting time value WT (i) by summing up the waiting times of all the destination floor calls assigned to the i-th car. The predicted waiting time table is generated each time a new destination floor call is generated or at predetermined time intervals based on the inter-level travel time table, the standard stop time at the stop floor, and the like. In the inter-floor travel time table, travel times between all floors are defined in a matrix. As the standard stop time, for example, an average stop time per stop during the past predetermined time or a predetermined time can be used.

  The group management control device 10 obtains a total value ST (i) of service completion times for all destination floor calls assigned to the i-th car (S25). Here, the service completion time is the time from the current time until the user can get off at the destination floor. Similar to the waiting time, the service completion time can be obtained based on a predicted waiting time table, a standard stop time, a door opening time, and the like.

  The group management control device 10 obtains the total waiting time value NWT (i) at the current time when a new destination call is assigned to the i-th car by the method similar to step S24 (S26).

  The group management control device 10 obtains the total value NST (i) of the service completion time when a new destination floor call is assigned to the i-th car by the method similar to step S25 (S27).

  The group management control device 10 obtains the delay penalty value penalty (i) from Equation 1 (S28). Specifically, the group management control device 10, when assigning a new destination floor call to the i-th car, delays the arrival time t (i) of the i-th car at the lobby floor after the new destination-floor call response (hereinafter referred to as “ Arrival delay time t (i) "). The arrival delay time t (i) can be obtained by the same waiting time prediction method as described above. Then, the group management control device 10 obtains a value obtained by multiplying the arrival delay time t (i) by the average number of passengers n obtained in step S22, and sets the obtained value as the delay penalty value penalty (i).

(Equation 1)
penalty (i) = t (i) × n

  The group management control device 10 obtains the evaluation value COST (i) of the i-th car using the formula 2 (S29).

(Equation 2)
COST (i) = NWT (i) −WT (i) + C1 (NST (i) −ST (i))
+ C2 × penalty (i)

  Here, C1 and C2 are constants. C1 and C2 are constants for performing weighting between parameters, and values appropriately adjusted by performing simulation under various conditions in advance are set. C2 × penalty (i) has a meaning as a waiting time addition value when evaluating COST (i). Hereinafter, C2 × penalty (i) is appropriately referred to as “waiting time addition value”.

  The group management control device 10 adds 1 to i (S30).

  The group management control device 10 determines whether i is larger than a predetermined value imax (S31). The predetermined value imax is the number of elevators that are group-managed by the group management control device 10. In this example, it is 3.

  If i is not greater than the predetermined value imax (NO in S31), the group management control device 10 returns to step S24 and performs the same processing for the i-th machine.

  When i is larger than the predetermined value imax (YES in S31), the group management control device 10 determines the machine having the smallest evaluation value COST (i), and sets the new destination floor to the machine having the smallest evaluation value COST (i). A call is assigned (S32).

  FIG. 5A is a diagram illustrating an example of an elevator operation diagram (when a new destination floor call is not assigned). FIG. 5B is a diagram showing an example of an elevator operation diagram (when a new destination floor call is assigned). 5A and 5B, FIG. 5A is a diagram schematically showing the allocation state of the destination floor call to the i-th car, and FIG. 5B shows the operation diagram of the i-th car.

2-5. Specific Example of Unit Allocation Operation A specific example of the unit allocation operation in consideration of the delay penalty value penalty (i) will be described. In FIG. 5A (a), call1 and call2 are assigned destination floor calls. callil3 is an unassigned new destination floor call. call1 is a destination floor call in which the departure floor is the first floor and the destination floor is the upward direction of the fifth floor. The call 2 is a destination floor call in which the departure floor is the fifth floor and the destination floor is the seventh floor upward. call3 is a destination floor call in which the departure floor is the fifth floor and the destination floor is the third floor downward.

  As shown in FIG. 5A (b), it is assumed that the No. i machine is currently located on the seventh floor. In FIG. 5A (b) and FIG. 5B (b), the operation line indicated by a solid line indicates an operation line when a new destination floor call is not assigned, that is, when a response is made only to the assigned destination floor call. On the other hand, in FIG. 5B (b), the operation line shown with a broken line shows an operation line at the time of assigning a new destination floor call. As shown in FIGS. 5A (b) and 5B (b), it is assumed that the i-th machine is currently located on the seventh floor.

(1) Total wait time WT (i) when responding only to assigned destination floor calls
As shown in FIG. 5A (b), when responding only to the assigned destination floor call, Unit i first descends from the seventh floor of the current position to the first floor, which is the departure floor of call1, and relates to call1. It stops for the stop time ts1 on the 1st floor for a user's boarding. Next, from the 1st floor, Unit i rises to the 5th floor, which is the destination floor of call1 and the departure floor of call2, and the 5th floor is used for getting off the users related to call1 and boarding the users related to call2. Stop at stop time ts5. Next, the No. i machine rises from the fifth floor to the seventh floor, which is the destination floor of call2, and stops at the seventh floor for a stop time ts7 in order to get off the user related to call2. And since there is no subsequent assigned destination floor call, the No. i machine descends from the seventh floor to the first floor, which is the lobby floor.

When the i-th car performs such operation, the waiting time wt1 for the call 1 is the traveling time tr71 from the 7th floor to the 1st floor of the i-th car. That is, the waiting time wt1 is expressed by the following equation.
wt1 = tr71
The travel time between the floors such as the travel time tr71 can be obtained based on a travel time table that defines the travel time between the floors.

The waiting time wt2 for call2 is expressed by the following equation.
wt2 = wt1 + ts1 + tr15
Here, ts1 is the stop time on the first floor, and tr15 is the travel time from the first floor to the fifth floor of the No. i machine.

And the total value WT (i) of the waiting time of the i-th car is expressed by the following equation.
WT (i) = wt1 + wt2

Also, the time rt1 from when the i-th machine finishes responding to call1 and call2 until it returns to the lobby floor is expressed by the following equation.
rt1 = wt2 + ts5 + tr57 + ts7 + tr71
Here, ts5 is the stop time on the 5th floor, tr57 is the travel time from the 5th floor to the 7th floor, ts7 is the stop time on the 7th floor, tr71 is the travel time from the 7th floor to the 1st floor of the i machine It is.

(2) Total waiting time NWT (i) when a new destination floor call is assigned
As shown in FIG. 5B (b), the i-th machine is currently located on the seventh floor. call3 is a destination floor call in which the departure floor is the fifth floor and the destination floor is the third floor downward. Therefore, call3 that is a new destination floor call is caused to respond earlier than call1 and call2.

When the i-th car performs such operation, the waiting time nwt3 for the call 3 is the traveling time tr75 from the 7th floor to the 5th floor of the i-th car. That is, the waiting time nwt3 is expressed by the following equation.
nwt3 = tr75

The waiting time nwt1 for call1 is expressed by the following equation.
nwt1 = nwt3 + ts5 + tr53 + ts3 + tr31
Here, ts5 is the stop time on the 5th floor, tr53 is the travel time from the 5th floor to the 3rd floor, ts3 is the stop time on the 3rd floor, tr31 is the travel time from the 3rd floor to the 1st floor of the i machine It is.

The waiting time nwt2 for call2 is expressed by the following equation.
nwt2 = nwt1 + ts1 + tr15
Here, ts1 is the stop time on the first floor, and tr15 is the travel time from the first floor to the fifth floor of the No. i machine.

And the total value WT (i) of the waiting time of the i-th car is expressed by the following equation.
NWT (i) = nwt3 + nwt1 + nwt2

In addition, the time nrt1 until the No. i machine finishes responding to call1, call2, and call3 and returns to the lobby floor is expressed by the following equation.
nrt1 = nwt2 + ts5 + tr57 + ts7 + tr71
Here, ts5 is the stop time on the 5th floor, tr57 is the travel time from the 5th floor to the 7th floor, ts7 is the stop time on the 7th floor, tr71 is the travel time from the 7th floor to the 1st floor of the i machine It is.

Here, when call 3 is assigned to the i-th car, the time for the i-th car to return to the first floor (lobby floor) in response to all the destination-floor calls including the new destination-floor call is later than when no call is assigned. This arrival delay time t (i) is expressed by the following equation.
t (i) = nrt1-rt1

  Further, the delay penalty value penalty (i) of the i-th car can be obtained by substituting the above-described t (i) and the average number of passengers n at the present time into the above-described equation 1. Further, the evaluation value COST (i) can be obtained by substituting NWT (i), WT (i), and delay penalty value penalty (i) into the above-described Expression 2.

  Then, the unit i having the smallest evaluation value COST (i) obtained for each unit is set as the assigned unit.

  As described above, by using the delay penalty value penalty (i) in the ACA evaluation, it becomes possible to appropriately control the service to passengers that will occur in the future according to the traffic situation. That is, since n approaches 0 when the traffic volume is small, allocation equivalent to the conventional ACA is performed. On the other hand, the value of n increases as the traffic volume increases, and the delay penalty value penalty (i) increases in proportion to the arrival delay time t (i) of arrival at the lobby floor. Allocation is started.

  For example, when a newly registered destination floor call is assigned to one of the units, if the planned stoppage floor of a unit overlaps the departure floor and destination floor of the new destination floor call, the new destination is not increased. Can answer floor calls. In this case, since the delay penalty value penalty (i) for arrival at the lobby floor is almost 0, the delay penalty value penalty (i) also approaches 0, and there is a high possibility that a new destination floor call will be assigned to the relevant machine. As a result, one lap time from when each elevator leaves the lobby floor until it returns is shortened. Therefore, at the time of traffic peak such as at work where passengers are concentrated on the lobby floor, it becomes possible to improve the transport capacity of the elevator and transport passengers appropriately.

  FIG. 6 is a diagram illustrating another example of an elevator operation diagram. FIG. 5 shows an example of responding to a new destination floor call before assigned call1 and call2, whereas FIG. 6 responds to a new destination floor call after assigned call1 and call2. An example is shown. In such a case, as in the example shown in FIG. 5, the delay penalty value penalty (i) and the evaluation value COST (i) are obtained based on the arrival delay time t (i), and the assigned number can be determined. . Therefore, even in such a case, it is possible to improve the elevator transportation capacity and appropriately transport passengers at the time of traffic peak such as when the passengers concentrate on the lobby floor.

The group management control device 10
About each unit
When a new destination floor call is assigned to the relevant unit, the total waiting time NWT (i) until a user associated with each destination floor call assigned to the relevant unit can board the relevant unit (First waiting time total value) and
When no new destination floor call is assigned to the relevant unit, the total waiting time WT (i) until a user associated with each destination floor call assigned to the relevant unit can board the relevant unit (Second waiting time total value) and
When a new destination floor call is assigned, the delay time t (i) based on the delay time t (i) of arrival of the relevant unit to the specific floor and the average number of passengers n on the specific floor based on the past learning results. ) Is longer, and as the average number of passengers n is larger, a waiting time addition value (C2 × penalty (i)) that becomes a larger value is obtained,
Further, the waiting time addition value (C2 × penalty) is subtracted from the waiting time total value WT (i) (second waiting time total value) from the waiting time total value NWT (i) (first waiting time total value). (I)) is added to obtain a value (NWT (i) −WT (i) + C2 × penalty (i)),
This added value (NWT (i) −WT (i) + C2 × penalty (i)) is used as one parameter of the evaluation value COST (i) relating to allocation in the relevant unit.

  As described above, in the present embodiment, when the evaluation value COST (i) related to allocation is obtained based on ACA, the longer the delay time of arrival at a specific floor when a new destination floor call is allocated, A waiting time addition value (C2 × penalty (i)) that increases as the average number of passengers n on the specific floor based on the learning result increases. Therefore, the waiting time of passengers expected to occur in a specific floor in the future is reflected in the allocation. Therefore, even in a time zone where many users are concentrated on a specific floor, it is possible to appropriately perform unit allocation using adaptive call allocation (ACA).

In this embodiment,
The specific floor is a floor connecting the building where the elevator 40 is installed and a passage outside the building.

  On the floor connecting the building where the elevator 40 is installed and the passage outside the building, passengers tend to concentrate in the commuting time zone and the above-mentioned problems are likely to occur. Can be performed more appropriately.

The group management system of this embodiment is
A destination floor registration device 20 (destination floor acquisition device) for acquiring a destination floor of the user and generating a new destination floor call;
And a group management control device 10 that assigns a new destination floor call acquired by the destination floor registration device 20 to any one of a plurality of elevators 40.

(Embodiment 2)
An elevator group management control apparatus according to Embodiment 2 will be described. In the second embodiment, the delay penalty value penalty (i) used when obtaining the waiting time addition value (C2 × penalty (i)) is obtained based on Equation 3. The difference from the first embodiment is that (n / maxn) ² is further multiplied to t (i) × n. Here, maxn is the maximum number of people that can get in the car.

(Equation 3)
penalty (i) = t (i) × n × (n / maxn) ²

The reason for further multiplying (n / maxn) ² is as follows. That is, when the traffic volume is relatively small, even if the operation of the car is delayed, there is no direct increase in waiting time for future passengers. This is because if there is a car that arrives at the lobby floor earlier than the car, more passengers can be assigned to the first car. In that case, simply adding the delay penalty value penalty (i) may lead to deterioration of the average waiting time during quiet periods. In order to prevent this, for example, by multiplying the delay penalty value penalty (i) by the square of the boarding rate, the influence of the delay penalty value penalty (i) is reduced when the average number of passengers n is small (that is, the traffic volume is small). It can be kept low.

As described above, in this embodiment,
The waiting time addition value (C2 × penalty (i)) is a value proportional to a value obtained by multiplying the average number of passengers n by the square of the boarding rate.

  As a result, when the average number of passengers n is small, the influence of the delay penalty value penalty (i) can be kept low.

(Other embodiments)
In each of the above embodiments, the control unit of the group management control device 10 or the destination floor registration device 20 is configured using a CPU, MPU, and the like, and uses various data based on a program read from the storage unit. Various functions are realized by performing arithmetic processing. That is, the control unit is realized by cooperation of hardware and software. However, the control unit may be configured by using, for example, only hardware (electronic circuit), FPGA, ASIC, or the like.

  In the said embodiment, the group management control apparatus 10 of an elevator allocates the destination floor input in the destination floor registration apparatus 20 to one of the elevators (units) of the plurality of elevators 40-1 to 40-3. Take control. However, depending on the building, a security gate for permitting or blocking the user's entry into the elevator hall is arranged, and the destination floor corresponding to the card ID read from the ID card can be obtained at the security gate. There is a case. In such a building, the elevator group management control device 10 sets the destination floor corresponding to the card ID read from the ID card in the security gate to any one of the elevators 40-1 to 40-3. It is possible to perform control assigned to the elevator (unit), and the technical idea of the present invention is also applicable to such a case. Alternatively, both the destination floor registration device 20 and the security gate are arranged, and the destination floor acquired by any means is assigned to any one of the elevators 40-1 to 40-3. It is possible to perform allocation control, and the technical idea of the present invention is also applicable to such a case.
