Description

The present invention relates to control technology for an elevator with multiple cars.

Among the control technologies for elevators equipped with a plurality of cars, there is a technique in which one of the cars is extracted in consideration of transportation efficiency for each hall call, and the hall call is assigned to the extracted car (for example, See Patent Document 1). In such a technology, under the premise that all cars operate at the same operating speed (including running speed, door opening speed, door closing speed, etc.), the floor where the hall call was made (boarding floor) In many cases, the estimated arrival time of each car is obtained, and one of the cars is extracted based on the estimated arrival time.

JP 2020-75771 A

On the other hand, in elevators, the car may be replaced with a new one, such as in the case of renewal. In general, cars are exchanged one by one, and it takes a long time. Therefore, when the cars are replaced, the old and new cars are mixed. And, since the operating speed (including running speed, door opening speed, door closing speed, etc.) of a new car is generally faster than that of an old car, the operating speed differs when replacing cars. Cars will be mixed.

However, in such a situation where cars with different operating speeds coexist, if it was assumed that all the cars would operate at the same operating speed as in the past, the floor where the hall call was made ( It becomes difficult to accurately calculate the estimated time of arrival of each car to the boarding floor. For this reason, it becomes difficult to extract an appropriate car, which may make it difficult to maintain high transportation efficiency.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to realize high transport efficiency in an elevator even in a situation where cars with different operating speeds are mixed.

A control device according to the present invention is applicable to an elevator having a plurality of cars, and includes a grouping processing section, an allocation processing section, and an update processing section. The grouping processing unit sets the time required for the car to perform the first predetermined action as a first action time, and organizes the cars into at least one group according to the measured value of the first action time, and The time required for performing the second predetermined operation is defined as the second operation time, and each group is associated with a set value of the second operation time commonly used for cars belonging to the group. When there is a hall call, the allocation processing unit extracts any one car using the setting value of the second operation time associated with each group, and allocates to the car. The update processing unit updates the set value of the second operating time associated with each group using the actually measured value of the second operating time for the car belonging to the group.

According to the above control device, when a situation arises in which cars with different operating speeds coexist, the cars are grouped into several groups based on the actual measurement values of the first operating time, and each group is updated using the actually measured value of the second operation time for the cars belonging to the group. By repeatedly updating the set value of the second operating time for each group, the set value can be converged to an appropriate value according to the operating speed of the car belonging to the group.

Therefore, even in a situation where cars with different operating speeds coexist, when extracting a car to which a hall call is to be assigned, the The estimated arrival time can be accurately calculated using an appropriate value for the set value of the second operating time associated with each group. By extracting a car based on such an accurate estimated time of arrival, it becomes possible to allocate a hall call to an appropriate car capable of achieving high transportation efficiency.

In the control device described above, the first predetermined operation may be a first traveling operation in which the car moves in a predetermined section. It can be time. Alternatively, the second predetermined motion may be a second traveling motion in which the car moves from the departure floor to the destination floor. It can be time. Then, the grouping processing unit may associate, for each group, the set value of the second travel time required for each combination of the departure floor and the destination floor as the set value of the second operation time.

In the control device described above, both the first predetermined operation and the second predetermined operation may be the car door opening operation or the door closing operation.

Advantageous Effects of Invention According to the present invention, high transport efficiency can be achieved in an elevator even in a situation where cars with different operating speeds coexist.

Specifically, the device management data D1 is data in which the device address Pa and the installation floor Fs as other information related to the destination floor registration device 101 are associated in advance and stored for each device information Pd1 of the destination floor registration device 101. (see FIG. 2(A)).

The installation floor Fs is the floor where the destination floor registration device 101 identified by the device information Pd1 is installed. The information management data Dp will be described in detail in the grouping process described below.

The control unit 3 is a processing device such as a CPU, and executes grouping processing, update processing, and allocation processing as control processing for controlling elevators. Specifically, it is as follows.

In the grouping process, the control unit 3 sets the time required for the car 100 to perform the first predetermined action as the first action time, and classifies the car 100 into at least one group according to the measured value of the first action time. Combined into Gc.

In the present embodiment, the first predetermined motion is a running motion (hereinafter referred to as "first running motion") in which the car 100 moves in the predetermined section Rt. The first motion time is the running time required for the first running motion (hereinafter referred to as "first running time T1"). More specifically, the predetermined section Rt is a section from a specific departure floor Fmt (for example, 1st floor) to a specific destination floor Fnt (≠Fmt; for example, 7th floor). 100 is the time required to move from a specific departure floor Fmt to a specific destination floor Fnt without stopping on the way. Then, the control unit 3 acquires the actual measurement value T1r of the first travel time T1 (first operation time) from each of all the cars 100, and determines the length of the car 100 according to the length of the acquired actual measurement value T1r. into at least one group Gc.

Here, the predetermined section Rt is set, for example, from the lowest floor to the highest floor so that a difference is likely to appear in the actual measurement value T1r of the first travel time T1 when cars 100 having different operating speeds are mixed. is preferably set to a relatively long section such as a section of . Note that the predetermined section Rt is not limited to the section from the specific departure floor Fmt to the specific destination floor Fnt. If possible, it may be set in various sections covering part or all of the moving range of the car 100 .

Furthermore, in the grouping process, the control unit 3 sets the time required for the car 100 to perform the second predetermined motion as the second motion time, and associates the set value of the second motion time with each group Gc described above. Here, the set value of the second operating time associated with each group Gc is commonly used when controlling the cars 100 belonging to the group Gc.

In this embodiment, the second predetermined motion is a running motion (hereinafter referred to as a "second running motion") in which the car 100 moves from the departure floor Fm to the destination floor Fn (≠Fm) without stopping. be. The second operation time is the running time required for the second running motion (hereinafter referred to as "second running time T2 (Fm, Fn)"). Then, for each group Gc, the control unit 3 sets the set value T2s (Fm, Fn) for the second travel time T2 (Fm, Fn) required for each combination (Fm, Fn) of the departure floor Fm and the destination floor Fn. ) as the set value of the second operation time. Further, the control unit 3 stores the set values T2s (Fm, Fn) associated with each group Gc in the storage unit 2 as the information management data Dp (see FIG. 2B).

Here, when the setting value T2s (Fm, Fn) is associated with each created group Gc for the first time, the control unit 3 uses an initial value prepared in advance for each group Gc to correspond to each group Gc. attach. As an example, a theoretical value obtained by simulation or the like is used as the initial value. FIG. 2B shows the state of the information management data Dp when each group Gc is associated with the initial value of the set value T2s.

Moreover, such grouping processing is executed each time a predetermined condition is satisfied. Here, the predetermined conditions include, for example, a condition that a new actual measurement of the first traveling time T1 (that is, a new acquisition of the actual measured value T1r) is completed in all cars 100, or a predetermined period (all A period during which it can be assumed that a new actual measurement of the first travel time T1 will be completed in the car 100. For example, a condition that one day or one week elapses is included. Then, each time the grouping process is executed, the group Gc is reviewed, and the set value T2s (Fm, Fn) is newly associated with each group Gc.

In the present embodiment, the information of each group Gc (set values T2s (Fm, Fn) associated with each group Gc) stored in the information management data Dp is stored in the group supervisory control device 103, which will be described later. is commonly used for the cars 100 belonging to the group Gc in the assignment process. Specifically, as a process for extracting the car 100 to be allocated, when calculating the estimated arrival time Tp of each car 100 to the floor (boarding floor Fc) where the hall call was made, each Information on the group Gc is commonly used for the cars 100 belonging to the group Gc.

In addition, the group supervisory control device 103 can refer to the information management data Dp and execute the allocation process even in a period until the grouping process is executed for the first time, such as immediately after the elevator starts operating. The following information is stored in advance in the management data Dp. As an example, assuming that all the cars 100 are grouped into one group Gc, the setting values T2s (Fm, Fn) (initial values prepared in advance) are associated only with the one group Gc ( For example, only the lower part of FIG. 2B) is saved in the information management data Dp.

In the updating process, the control unit 3 actually measures the second travel time T2 (Fm, Fn) (second operation time) in each car 100, and updates the second travel time T2 ( Fm, Fn) setting value T2s (Fm, Fn) is updated using the actual measurement value T2r (Fm, Fn) of the second travel time T2 (Fm, Fn) for the car 100 belonging to the group Gc. .

In the assignment process, when there is a hall call (that is, when information necessary for elevator control (including destination floor Fd and device information Pd1) is received from destination floor registration device 101), Any one car 100 is extracted, and a hall call is assigned to the car 100. - 特許庁Specifically, for each car 100, the control unit 3 sets the set value T2s (Fm, Fn) of the second travel time T2 (Fm, Fn) associated with the group Gc to which the car 100 belongs. is used to calculate the estimated arrival time Tp at the floor (boarding floor Fc) where the hall call was made. Then, based on the calculated estimated arrival time Tp, the control unit 3 extracts any one car 100 that is most suitable for transportation, and allocates a hall call to that car 100 .

According to such a series of processes, when a situation arises in which cars 100 with different operating speeds coexist, those cars 100 will have the length of the actual measurement value T1r of the first running time T1 (first operating time). setting values T2s (Fm, Fn ) is updated using the measured value T2r (Fm, Fn) of the second travel time T2 (Fm, Fn) for the car 100 belonging to the group Gc. Here, the situation where the cars 100 with different operating speeds are mixed is not limited to the case where the old and new cars 100 are mixed due to replacement, but also the case where the cars 100 whose speed is reduced due to failure etc. are mixed. and the case where there are mixed cars 100 that are operated at low speed due to maintenance or the like.

Then, by repeating updating of the set value T2s (Fm, Fn) for each group Gc, the set value T2s (Fm, Fn) is appropriately set according to the operation speed of the car 100 belonging to the group Gc. can be converged to a value

Therefore, even in a situation where cars 100 with different operating speeds coexist, when extracting the car 100 to which the hall call is to be assigned, each floor to which the hall call was made (boarding floor Fc) The estimated arrival time Tp of the car 100 is accurately calculated using an appropriate value for the set value T2s (Fm, Fn) of the second travel time T2 (Fm, Fn) associated with each group Gc. becomes possible. By extracting the car 100 based on such an accurate estimated time of arrival Tp, it becomes possible to allocate the hall call to an appropriate car 100 that can achieve high transportation efficiency.

In this embodiment, grouping processing, updating processing, and allocation processing are executed by a grouping processing unit 31, an updating processing unit 32, and an allocation processing unit 33, respectively, which are configured in the control unit 3 (see FIG. 1). ). Specifically, these processing units are composed of software by causing a processing device (such as a CPU), which is the control unit 3, to execute a program, and such a program is stored in the storage unit 2. ing. The program may be stored in a portable storage medium in a readable state, read from the storage medium and stored in the storage unit 2, or may be stored in a server or the like so as to be downloaded, Those downloaded from the server may be stored in the storage unit 2 . Note that the above processing unit may be configured by hardware by constructing the control unit 3 in the group supervisory control device 103 with a circuit.

Details of the grouping process, update process, and allocation process executed by the group supervisory control device 103 will be described below.

[2] Control Processing Executed by Group Supervisory Control Device [2-1] Grouping Processing FIG. The grouping process is started when the predetermined condition described above is satisfied.

When the grouping process is started, the control unit 3 of the group supervisory control device 103 acquires information of the car 100 obtained from each car 100 (specifically, the elevator control device 102 corresponding to the car 100). Using the car information Pc and the measured value T1r (in this embodiment, the latest measured value T1r) of the first travel time T1 in the car 100 as one set of data (Pc, T1r), from all cars 100 The obtained values are sorted in ascending order of the measured value T1r (step S101). In step S101, the control unit 3 uses the number i representing the sorting order when the data (Pc, T1) after sorting with the smallest actual measurement value T1r is first, and sorts the data (Pc, T1) after sorting (Pc , T1r), they are set as data (Pc(i), T1r(i)).

Next, the control unit 3 sets the group number Ng to Ng=1 (step S102). Here, the group number Ng is a number for identifying the group Gc. Then, the control unit 3 creates a group Gc (Ng) having a group number Ng (here, Ng=1). For identification of the group Gc, not only the group number Ng but also various information (for example, symbols, alphabets, etc.) that enables identification of the group Gc may be used. Also, the setting of the group number Ng (Ng=1) may be appropriately executed at another timing, such as before step S101, as long as it is before creating the group Gc (Ng).

After that, the control unit 3 assigns the car information Pc(1), which is the first in the sorting order, to the group Gc(Ng) in order to sort the car 100 with the smallest measured value T1r into the group Gc(1). Add (step S103).

Then, the control unit 3 sets the variable J to J=1 and sets the variable k to k=2 (step S104). Here, the variable J is a variable for substituting a specific number out of the numbers i representing the sorting order. Also, the variable k is a variable representing the number i representing the sorting order that is to be processed at each time step S110, which will be described later, is repeatedly executed. Then, the variable k is sequentially incremented by one during the grouping process (see step S112). Note that if the variables J and k are set (J=1, k=2) before step S110 (selection of cars 100) described later, timing different from step S104 (for example, before step S101) stroke) may be executed as appropriate.

More specifically, the variable J is a variable set as follows.

In this embodiment, in step S110 to be described later, the control unit 3 assigns the cars 100 to be assigned to the group Gc(1) (that is, the cars 100 to be grouped as the group Gc(1)) to the group Gc(1) first. Selection is made by comparing actual measurement values T1r with the sorted cars 100 . Therefore, in step S104, the control unit 3 performs Set the variable J to J=1.

As will be described later, when the control unit 3 creates another new group Gc (Ng) (see step S121), the control unit 3 selects the remaining cars 100 that have not been sorted at that time. Among them, the one with the smallest actual measurement value T1r (that is, the car 100 with the lowest sort order among the remaining cars 100) is sorted into the group Gc (Ng). After that, the control unit 3 adds the car information Pc(k) corresponding to the value of the variable k to be processed at that time to the group Gc(Ng) (see step S122).

In this case, in step S110 that is executed thereafter, the control unit 3 moves the cars 100 to be assigned to the group Gc(Ng) (that is, the cars 100 to be grouped as the group Gc(Ng)) to the group Gc(Ng) first. are sorted by comparing the measured value T1r with the car 100 sorted into . Therefore, when another new group Gc(Ng) is created (see step S121), the control unit 3 determines the actual measurement value T1r(k) of the car 100 first assigned to the group Gc(Ng) can be referred to in the subsequent step S110, the variable J is changed using the value of the variable k at the time when the actual measurement value T1r (k) is first distributed to the group Gc (Ng). Change J=k (step S123).

After the execution of step S104, the control unit 3 sets the value of the variable k to be processed at that point in order from the second sort order in order to select the cars 100 to be assigned to the group Gc (Ng). The corresponding measured value T1r(k) and the measured value T1r(J) corresponding to the value of the variable J at that time (that is, the measured value T1r of the car 100 first assigned to the group Gc(Ng)) is used to determine whether the ratio (T1r(k)/T1r(J)) minus 1 is within the range of error p (step S110).

Here, the error p is as follows. First, the value of the variable k to be processed when step S110 is executed is greater than the value of the variable J at that time, so the sorting order is later than the value of the variable J. Therefore, the measured value T1r(k) is equal to or larger than the measured value T1r(J). Therefore, it is clear that the above ratio (T1r(k)/T1r(J)) will be 1 or more. If those cars 100 are of the same type, the measured values T1r are often almost the same, and their differences are often within the margin of error. Therefore, the ratio of such errors is used as the error p.

Therefore, when the control unit 3 determines that "the error is within the range of p (Yes)" in step S110, the control unit 3 determines that the car 100 being targeted at that time (that is, The cars 100 identified by the car information Pc(k) corresponding to the value of the variable k to be processed (the same applies hereinafter) are of the same type as the cars 100 first assigned to the group Gc(Ng). It can be determined that the On the other hand, when the control unit 3 determines in step S110 that it is not within the range of the error p (No), the car 100 being targeted at that time is classified into the group Gc (Ng). It can be determined that the car 100 is of a different type from the first sorted car 100.

Therefore, when the control unit 3 determines that "the error is within the range of p (Yes)" in step S110, the control unit 3 divides the car 100 targeted at that time into the group Gc (Ng). The car information Pc(k) of the car 100 (that is, the car information Pc(k) corresponding to the value of the variable k to be processed at that time) is added to the group Gc(Ng) (step S111). .

On the other hand, when the control unit 3 determines that "not within the range of the error p (No)" in step S110, in order to sort the car 100 being targeted at that time to another new group Gc, The group number Ng is changed to Ng=Ng+1, and a new group Gc(Ng) having the changed group number Ng is created (step S121).

After that, the control unit 3 selects the car 100 that has the smallest actual measurement value T1r among the cars 100 remaining unsorted at that time (that is, the car 100 that has the earliest sort order among the remaining cars 100). to the group Gc(Ng), the car information Pc(k) corresponding to the value of the variable k to be processed at that time is added to the group Gc(Ng) (step S122).

Then, the control unit 3 controls the actual measurement value T1r(k) of the car 100 first assigned to the group Gc(Ng) so that it can be referred to in subsequent step S110. , the variable J is changed to J=k (step S123).

After executing step S111 or S123, the control unit 3 changes the variable k to k=k+1 in order to change the processing target to the next one in sort order (step S112). After that, the control unit 3 determines whether or not the value of the variable k at that time has exceeded the total number of cars Nc (the total number of cars 100) (step S113). Then, when the control unit 3 determines that "not exceeded (No)" in step S113, the allocation to all the cars 100 has not been completed (that is, the allocation has not been completed). It can be determined that there is a car 100 that is empty). On the other hand, if the control unit 3 determines "exceeded (Yes)" in step S113, it can determine that the allocation to all the cars 100 has been completed.

Therefore, when the control unit 3 determines that "not exceeded (No)" in step S113, it returns to step S110, and until it determines that "it has exceeded (Yes)" in step S113, the control unit 3 continues from step S110. Execute the process repeatedly. On the other hand, if the control unit 3 determines “exceeded (Yes)” in step S113, the set value T2s (Fm, Fn) of the second traveling time T2 (Fm, Fn) is calculated for each created group Gc. ) are associated with each other, and the associated data is stored as information management data Dp in the storage unit 2 (step S114; see FIG. 2B). In FIG. 2B, car information Pc(1) is assigned to group Gc(1) with group number Ng=1, and car information Pc(2) is assigned to group Gc(2) with group number Ng=2. ) and Pc(3) are shown.

According to such a grouping process, when a situation arises in which cars 100 with different operating speeds coexist, how many cars 100 are divided based on the length of the measured value T1r of the first travel time T1. They are automatically grouped into one group Gc. Although FIG. 2B shows a case where two groups Gc are created, according to the grouping process described above, only one group Gc is created according to the situation of the elevator. In some cases, there may be three or more groups Gc.

[2-2] Update Processing FIG. 4 is a flow chart showing update processing executed by the group supervisory control device 103 . The update process starts when the grouping process is completed and continues until the next grouping process is executed and completed. Then, when the next grouping process is completed, the group supervisory control device 103 terminates the update process that has been executed so far (see step S209), and then starts a new update process. In the following description, the setting values T2s(Fm, Fn) associated with each group Gc in the information management data Dp are expressed as the setting values T2s(Gc , Fm, Fn).

When the update process is started, the control unit 3 of the group supervisory control device 103 updates the variables St (X, Y1, Y2) and Sn (X, Y1, Y2) for all combinations of the variables X, Y1, and Y2. Reset (step S201). Specifically, the control unit 3 sets the variable St(X, Y1, Y2) to St(X, Y1, Y2)=0, and sets the variable Sn(X, Y1, Y2) to Sn(X, Y1, Y2). Y2)=0.

Here, the variables X, Y1, and Y2 are variables in which the group number Ng, the departure floor Fm, and the destination floor Fn targeted in the course of the updating process are appropriately stored, respectively (see step S204). Variables St (X, Y1, Y2) and Sn (X, Y1, Y2) are measured values T2r of second travel times T2 (Y1, Y2) obtained in cars 100 belonging to group Gc (X) of variable X. Variables representing the sum of (Y1, Y2) and the number of times the measured value T2r(Y1, Y2) was obtained in the group Gc(X) of the variable X, respectively. As will be described later, the variables St(X, Y1, Y2) and Sn(X, Y1, Y2) are obtained by calculating St(X, Y1, Y2)/Sn(X, Y1, Y2). Calculate the average value Tav (X, Y1, Y2) of the measured values T2r (Y1, Y2) in Gc (X), and use the average value Tav (X, Y1, Y2) to set the set value T2s (X, Y1, Y2) ) is used to update the

Next, the control unit 3 controls the car information Pc of each car 100, the measured value T2r (Fm, Fn) of the second traveling time T2 (Fm, Fn) obtained in the car 100, and the measured value T2r (Fm, Fn). Departure floor Fm and destination floor Fn corresponding to T2r are regarded as a set of data, and it is determined whether or not the set of data has been acquired from any of the cars 100 (step S202). Then, the control unit 3 repeatedly executes step S202 until it can be determined that "acquired (Yes)" in step S202.

If it is determined that "acquired (Yes)" in step S202, the control unit 3 uses the car information Pc in the acquired data to determine whether the car 100 identified by the car information Pc belongs. The group number Ng of the group Gc in which it is present is determined (step S203). Specifically, the control unit 3 associates the group number Ng (see FIG. 2B) stored in the information management data Dp that matches the car information Pc acquired in step S202. Extract the group number Ng from

After that, the control unit 3 substitutes the group number Ng determined in step S203 into the variable X, and substitutes the departure floor Fm and the destination floor Fn acquired in step S202 into the variables Y1 and Y2, respectively (step S204).

After executing step S204, the control unit 3 adds the actual measurement value T2r (Fm, Fn) acquired in step S202 to the variable St (X, Y1, Y2) to A sum of values T2r (Y1, Y2) is obtained (step S205). Further, the control unit 3 counts the number of times that the measured value T2r (Y1, Y2) is obtained in the group Gc (X) of the variable X by adding "1" to the variable Sn (X, Y1, Y2). (step S206). Note that steps S205 and S206 may be executed in reverse order.

After that, the control unit 3 uses the variables St (X, Y1, Y2) obtained in step S205 and the variables Sn (X, Y1, Y2) obtained in step S206 to Calculate the average value Tav (X, Y1, Y2) of the measured value T2r (Y1, Y2) by the formula: Tav (X, Y1, Y2) = St (X, Y1, Y2) / Sn (X, Y1, Y2) (step S207).

Then, the control unit 3 updates the set value T2s (X, Y1, Y2) using the average value Tav (X, Y1, Y2) obtained in step S207 (step S208). Specifically, the control unit 3 replaces the set value T2s (X, Y1, Y2) with the average value Tav (X, Y1, Y2) obtained in step S207.

According to such update processing, each time data is obtained from the car 100 in step S202, the set value T2s (X, Y1, Y2) corresponding to the data (that is, the group Gc (X) of the variable X is updated. By repeating such updating of the set value T2s (X, Y1, Y2), the set value T2s (X, Y1, Y2) is changed to the operation of the car 100 belonging to the variable X group Gc(X). It can converge to an appropriate value according to speed.

[2-3] Allocation Processing FIG. 5 is a flow chart showing allocation processing executed by the group supervisory control device 103 . The allocation process is started when the group supervisory control device 103 receives the information necessary for elevator control (including the destination floor Fn and the device information Pd1) from the destination floor registration device 101 .

When the allocation process is started, the control unit 3 of the group supervisory control device 103 uses the device information Pd1 included in the information (received information Pr1) received from the destination floor registration device 101 to extract from the device management data D1 , the device address Pa and installation floor Fs corresponding to the device information Pd1 are read (step S301). The installation floor Fs read here is the installation floor of the destination floor registration device 101 for which the destination floor Fd included in the received information Pr1 is input. Therefore, in the following processing, it is used as the boarding floor Fc at which the user who called the boarding place gets on the car 100 .

Next, the control unit 3 sets the installation floor Fs read in step S301 as the boarding floor Fc, and calculates the estimated arrival time Tp of each car 100 to the boarding floor Fc (step S302). Specifically, for each car 100, the control unit 3 sets the set value T2s of the second running time T2 (Fm, Fn) associated with the group Gc to which the car 100 belongs in the information management data Dp. (Fm, Fn) is used to calculate the estimated arrival time Tp at the boarding floor Fc (the floor where the floor was called).

As an example, if each car 100 is stopped at any floor at the time step S302 is executed, the control unit 3 controls each car 100 to move from the stop floor at that time to the boarding floor Fc. The time required for movement to Calculate Tp. Note that the estimated arrival time Tp may take into account the door opening time required for the door to open after each car 100 arrives at the boarding floor Fc. For the car 100 that needs to stop at another floor on the way, the second travel time T2 required to move to that floor, and the second travel time T2 required to move from that floor to the next stop floor. may be taken into account based on the set value T2s (Fm, Fn) in the information management data Dp, or the stopping time (including door open time and door closed time) at an intermediate floor to be stopped may be taken into consideration. good too.

After execution of step S302, the control unit 3 extracts any one car 100 most suitable for transportation based on the estimated arrival time Tp of each car 100 calculated in step S302 (step S303). As an example, the control unit 3 extracts the car 100 with the earliest estimated arrival time Tp (that is, the car 100 arriving at the boarding floor Fc first) as the car 100 most suitable for transportation.

Thereafter, the control unit 3 treats the boarding floor Fc and the destination floor Fd in the received information Pr1 as one hall call, and assigns the hall call to the car 100 extracted in step S303 (step S304). Then, the control unit 3 displays, on the touch panel 1 of the destination floor registration device 101 specified by the device address Pa in the received information Pr1, a notification screen for notifying the user of the car information Pc of the assigned car 100. (Step S305). In addition to the car information Pc, information such as the user's destination floor Fd may be displayed on the notification screen.

According to this allocation process, even in a situation where cars 100 with different operating speeds are mixed, when extracting the cars 100 to which the hall call is to be allocated, the floor ( The estimated arrival time Tp of each car 100 to the boarding floor Fc) is set to an appropriate value for the set value T2s (Fm, Fn) of the second traveling time T2 (Fm, Fn) associated with each group Gc. can be calculated accurately using By extracting the car 100 based on such an accurate estimated time of arrival Tp, it becomes possible to allocate the hall call to an appropriate car 100 that can achieve high transportation efficiency.

[3] Modification [3-1] First Modification In the grouping process described above, the first predetermined motion is replaced with the first running motion (the running motion of moving in the predetermined section Rt), and the door of the car 100 The operation of the car 100 may be appropriately changed to another operation such as a closing operation or a door opening operation. Then, another operation time for the car 100, such as the door closing time required for the door closing operation and the door opening time required for the door opening operation, may be used as the first operation time. That is, the control unit 3 may group the cars 100 into at least one group Gc based on actual measurements of such other operating times (door closed time, door open time, etc.).

In addition, in the above-described grouping process, the second predetermined motion is replaced with the second running motion (running motion moving from the departure floor Fm to the destination floor Fn), such as the door closing motion or the door opening motion of the car 100. Other operations for the car 100 may be changed as appropriate. Then, another operation time for the car 100, such as the door closing time required for the door closing operation and the door opening time required for the door opening operation, may be used as the second operation time. That is, the control unit 3 may associate the setting values for such different operating times with each group Gc. Then, in the updating process, the set value of the other operating time (door closed time, door open time, etc.) may be updated based on the actual measurement value of the operating time.
