Description

GROUP MANAGEMENT DEVICE OF ELEVATOR}

The present invention relates to an elevator group management apparatus for managing the operation of an elevator group composed of a plurality of elevators.

For example, in a conventional elevator group management system as shown in Patent Literature 1, when an elevator call occurs, the group management control device selects a car of an assignment candidate selected from among elevator groups and an elevator call operation. The time difference of arrival at the boarding floor of the user (passenger) who performed the calculation is calculated. And when the car of an assignment candidate arrives at the boarding point more than a predetermined time earlier than a user, the group management control apparatus removes the car from the assignment candidate of an elevator group, in order to suppress the fall of the running efficiency of an elevator group. As a result, the group management controller changes the assignment candidate to a car different from that of the car, and determines the assignment car that matches the condition.

Japanese Patent Laid-Open No. 2005-112520

Here, the boarding call in the same destination direction and in the same boarding direction may occur a plurality of times in a short time. That is, when a car does not leave from the boarding floor corresponding to the boarding call registered first (i.e., the boarding call of the registered completion), a new boarding call may be newly generated in the same boarding direction and at the same boarding floor as the boarding call of the registration completion. There is a case.

On the other hand, in the conventional group management system of an elevator, the criterion of which user to which user may be assigned to the same car is not appropriately given. For this reason, when a new boarding call having the same content as the registered boarding call is generated, a car that has been allocated to the boarding call with registration completed can also be allocated to the new boarding call. This extends the door opening waiting time of the car that has been allocated to the boarding call of the registration completion.

However, in this allocation control system, as the number of users increases, the door opening waiting time of the car at the boarding floor increases, and the waiting time of the user who first executes the boarding call operation after the car arrives increases. In addition, for a user who has performed a new boarding call operation, the car may close the door soon and start from the boarding floor, or the car may be full, so that it may not be possible to get on the car.

In addition, when the same car as the car with the extended door opening time is allocated in the boarding floor different from the boarding floor, the arrival time of the car in the other boarding floor is greatly delayed. .

Therefore, due to these factors, in the conventional group management system of an elevator as described above, when a plurality of users perform a landing call operation continuously, the running efficiency of the elevator decreases and the user's discomfort increases. There was a problem.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain an elevator group management apparatus that can improve the running efficiency of an elevator and can reduce the discomfort of a user.

The group management apparatus of an elevator according to the present invention manages the operation of an elevator group having a plurality of cars and, in response to a request for registering a boarding call from the boarding call registration device, a plurality of boarding points and destination directions corresponding to the boarding call. Registering a boarding call by allocating one of the cars as an allocating car, and when a new boarding call registration request occurs, a boarding call corresponding to the new boarding call with the same boarding direction and destination direction is already registered. If it is, the assignment candidate selection index calculation part which calculates the time difference of the boarding schedule time of the user who is going to board the last of the plurality of users who performed the registration call of the registration completion, and the user who performed the new boarding call as a 1st index, and Assigns, from a plurality of cars, an assignment candidate that is a candidate of the assigned car for the new boarding call; When the 1st index calculated by the selection index calculation part is larger than the 1st permissible value previously stored, it is provided with the assignment candidate selection part which removes the assignment car regarding the boarding call of registration completion from an assignment candidate.

EMBODIMENT OF THE INVENTION Hereinafter, the preferred embodiment of this invention is described with reference to drawings.

1st Embodiment

BRIEF DESCRIPTION OF THE DRAWINGS It is a perspective view which shows the periphery of the boarding point of the elevator which concerns on 1st Embodiment of this invention. It is a block diagram which shows the group management apparatus of the elevator which concerns on 1st Embodiment of this invention.

1 and 2, a plurality of elevators are provided in the building. The plurality of elevators constitute an elevator group. Each of the some elevator has cars 1A-1D.

The driving of the cars 1A to 1D is controlled by the individual car control devices 2A to 2D, respectively. The individual car control devices 2A to 2D are connected to the group management device main body 100. The group management apparatus main body 100 collectively manages the operation of the cars 1A to 1D, that is, the operation of the elevator group, via the individual car control devices 2A to 2D.

In addition, the remote boarding call registration devices 11A to 11E are provided at each boarding floor (one place in the building) at a predetermined distance from the boarding point 3 of the elevator (in FIG. 1, only 11A). Shown). Moreover, the remote boarding point registration devices 11A-11E are arrange | positioned, for example in the lobby floor of a building, the boundary of a general division and a management division in a building (namely, a division boundary). In addition, the remote boarding point registration devices 11A to 11E have an operation unit and a display unit. The remote boarding call registration apparatuses 11A to 11E are connected to the group management apparatus main body 100.

The remote boarding call registration devices 11A to 11E receive a boarding call operation from the user. This boarding call operation includes an operation for calling a car to the boarding floor, which is the boarding floor where the user gets on the car, and an operation for registering the getting off floor, which is the boarding floor that the user gets out of the car. In addition, the remote boarding point call registration devices 11A to 11E are operated by users of almost all elevators passing through the lobby floor, the partition boundary, and the like.

When remote boarding call registration apparatus 11A-11E receives a boarding call operation from a user, it sends the content of the boarding call operation to the group management apparatus main body 100 as a registration request (information information) of boarding call. With respect to the registration request of the boarding call, the group management apparatus main body 100 assigns one car among the cars 1A to 1D as the allocating car to the boarding floor of the boarding call registration request and registers the boarding call. .

In addition, when the group management device main body 100 registers the boarding call, the group management device main body 100 sends the information of the card number of the assigned car to the remote boarding call registration devices 11A to 11E as a response to the registration request of the boarding call. When the remote boarding call registration devices 11A to 11E receive the information of the assigned car number, the remote boarding call registration device 11 displays the assigned car number to the display unit to inform the user of the assigned car.

In addition, when the boarding device call registers the boarding call, the group management device main body 100 sends a driving instruction relating to the driving of the allotted car to the individual car control devices 2A to 2D corresponding to the allotted car. The individual car control devices 2A to 2D control the driving of the assigned car based on the operation command from the group management apparatus main body 100. Further, as the car control panel (not shown) provided in each of the individual car control devices 2A to 2D and the cars 1A to 1D is operated by the user, for example, the destination floor registration of the cars 1A to 1D ( Car call registration) and door open / close control.

Next, the structure of the group management apparatus main body 100 is demonstrated concretely. The group management apparatus main body 100 stores in advance the information of the expiration number of the cars 1A to 1D. Moreover, the group management apparatus main body 100 receives the information regarding the driving situation of the cars 1A-1D from the individual car control apparatuses 2A-2D. The information on the driving status of the cars 1A to 1D differs from the position of the cars 1A to 1D, the driving direction of the cars 1A to 1D, and the driving status of the cars 1A to 1D (whether they are running or waiting). , Door opening / closing conditions of the cars 1A to 1D, boarding point calls registered to the cars 1A to 1D, information on the destination floor registered to the cars 1A to 1D, and the like.

Here, when the group management apparatus main body 100 receives the registration request of the boarding call, the group management apparatus main body 100 selects an allocation car for the boarding call. If the group management apparatus main body 100 has already received a new boarding call registration request when the boarding call has already been registered, the new boarding call and the boarding call of the registration completion are in the same boarding floor and in the same destination direction. Check to see if it is a call. That is, the group management apparatus main body 100 confirms whether or not there is a boarding call of the registration completion in the same destination direction and at the same boarding floor as the new boarding call.

Then, when there is a boarding call of the registered completion in the same destination direction and in the same destination direction, the group management apparatus main body 100 determines whether or not the allocation car for the registered boarding call is also assignable to the new boarding call. The allocation car for the registered boarding call or a car other than the allocated car is allocated to the new boarding call.

In addition, the group management apparatus main body 100 includes an allocation candidate selection index calculation unit 120, an allocation candidate selection unit 130, a moving constant setting unit 140, an allocation car determination unit 150, and an operation command unit 160. Have The assignment candidate selection index calculation unit 120 calculates the assignment candidate selection indicators (first indicator and second indicator). The allocation candidate selection index is an index for selecting (extracting) an allocation candidate which is a candidate of the allocation car for the new boarding call among all the cars 1A to 1D.

The assignment candidate selection unit 130 is based on the information on the assignment candidate selection index from the assignment candidate selection index calculation unit 120 and the driving conditions (operation status of the elevator group) of the cars 1A to 1D. 1A to 1D) are evaluated for assignability. Then, the assignment candidate selecting unit 130 selects an assignment candidate that is a candidate of the assignment car based on the evaluation result. The assignment candidate selecting unit 130 also stores an assignment candidate list which is a list of the car number of the selected assignment candidate. In addition, when the boarding call occurs, the assignment candidate selecting unit 130 selects an assignment candidate from all cars 1A to 1D, and updates the assignment candidate list stored therein.

The moving constant setting unit 140 includes information on the distance between the remote boarding call registration devices 11A to 11E and the corresponding lifting positions (that is, the boarding gate (car front)) of all the cars 1A to 1D, respectively. Is stored in advance as the moving distance information. In addition, the moving constant setting unit 140 previously stores the standard value of the moving speed (walking speed) of the user as the moving speed information. When the remote boarding call registration devices 11A to 11E are operated by the user, the moving constant setting unit 140 responds to the remote boarding call registration devices 11A to 11E that have received the new boarding call operation and the new boarding call. The movement distance information between the ride positions of all cars 1A to 1D and the movement speed information are sent to the assignment candidate selection index calculation unit 120.

The allocation car determination unit 150 refers to the allocation candidate list generated by the allocation candidate selecting unit 130, selects a car whose increase in the total waiting time becomes minimum when allocating among the cars of the allocation candidates, and selects the car. Determine as allocation car. In addition, the allocation car determination unit 150 transmits the information of the breath number of the selected allocation car to the driving command unit 160. The driving command unit 160 sends a driving command relating to the driving of the allocating car to the individual car control devices 2A to 2D corresponding to the allocating car determined by the allocating car determining unit 150.

Next, the configurations of the assignment candidate selection index calculation unit 120 and the assignment candidate selection unit 130 in FIG. 2 will be described in detail. FIG. 3 is a block diagram illustrating in detail the allocation candidate selection index calculator 120 and the allocation candidate selection unit 130 of FIG. 2. In addition, in FIG. 3, the individual car control apparatuses 2A-2D, the moving constant setting part 140, the allocation car determination part 150, and the driving command part 160 are abbreviate | omitted and shown.

In FIG. 3, the assignment candidate selection index calculation unit 120 includes the car arrival prediction time calculation means 21, the user arrival prediction time calculation means 22, the door opening waiting time calculation means 23, and the ride scheduled time interval. The calculation means 24 is included. The car arrival prediction time calculating means 21 is a prediction time at which each of the cars 1A to 1D arrives at the boarding floor corresponding to the new boarding call on the basis of the time when the registration request of the new boarding call is generated, that is, the car arrival prediction time. To calculate. This car arrival prediction time is computed by the car arrival prediction time calculation means 21 based on the information regarding the driving condition of the cars 1A-1D from the individual car control apparatuses 2A-2D.

The user arrival prediction time calculation means 22 calculates the prediction time at which the user arrives at each of the ride positions of the cars 1A to 1D, that is, the user arrival prediction time, based on the time when the registration request of the boarding call is generated. The user arrival prediction time is calculated by the user arrival prediction time calculation means 22 based on the standard moving speed information and the standard moving speed information from the moving constant setting unit 140.

The door opening waiting time calculation means 23 receives the information of the car arrival prediction time from the car arrival prediction time calculation means 21. In addition, the door opening waiting time calculation means 23 receives the information of the user arrival prediction time from the user arrival prediction time calculation means 22. In addition, the door opening waiting time calculation means 23 lists and stores the user arrival prediction time in time series.

In addition, the door opening waiting time calculation means 23 assumes that when the new boarding call occurs, each of the cars 1A to 1D can be assigned to the boarding floor corresponding to the boarding call, and the car 1A to 1D. ) Is calculated as the second index of the door opening waiting time of each of the cars 1A to 1D when the car reaches the boarding floor. This door opening waiting scheduled time is the time when the car will wait to open the door at the boarding point 3 after the car arrives at the boarding point 3. The door opening waiting time is calculated by the door opening waiting time calculation means 23 based on the list of car arrival prediction time and the user arrival prediction time.

The boarding schedule time interval calculating means 24 receives the information of the car arrival predicting time from the car arrival predicting time calculating means 21. Moreover, the boarding schedule time interval calculating means 24 receives the information of the car arrival prediction time from the user arrival prediction time calculating means 22. In addition, the boarding schedule time interval calculating means 24 lists and stores the information of the arrival prediction time of the user in time series similarly to the door opening waiting time calculating means 23.

In addition, the boarding schedule time interval calculating means 24 is the arrival predicted time which is a time difference between the boarding schedule time of the user who executed the boarding call operation of the registration completion immediately before the new boarding call operation and the user who executed the new boarding call. The interval is calculated as the first index based on the list of arrival prediction time of the user.

Next, with respect to the calculation method of the door opening waiting time calculation means 23 by the door opening waiting time calculation means 23 of FIG. 3, and the calculation method of the riding schedule time interval by the riding schedule time interval calculation means 24, It demonstrates more concretely. Here, the estimated arrival time of the door opening waiting time is tw, and the scheduled time interval of the ride is tint, and the arrival prediction time of the car 1A at the ride floor is called CarPT (A).

In addition, it demonstrates using three users x, y, and z here. The user x, y and z are as follows.

User x: A user who first arrives at the boarding position of the car 1A among a plurality of users who have performed the boarding call operation of registration completion.

User y: The user who finally arrives at the boarding position of the car 1A among the plurality of users who have performed the boarding call operation of the registration completion.

User z: User who performed the new board call operation

Here, the time (current time) when user z performed a new boarding call operation is called T = 0. In addition, the arrival prediction time of users x, y, and z is called HT (x), HT (y), and HT (z), respectively. However, when the car 1A arrives at the boarding floor corresponding to the new boarding call in the same direction as the boarding call, the user who boarded the car 1A from another boarding floor does not get off. It is assumed that HT (x) = {arrival prediction time of car 1A to the ride floor}.

At this time, the door opening waiting time tw is represented by the following equation (1).

[Equation 1]

That is, the door opening waiting time tw is a time of predicting arrival of the assigned car to the boarding floor regarding the boarding call, the scheduled time of boarding the assigned car of the user who has executed the boarding call of registration completion, and the new boarding call. It is based on the relationship of three time of the riding schedule time of the user who performed.

Further, the scheduled ride time interval tint is expressed by the following equation.

[Equation 2]

Moreover, in the boarding floor corresponding to a new boarding call, when there is no user who is going to ride (assignment completion) in the car 1A, the door opening waiting time calculation means 23 as x = y = z. ) And the boarding schedule time interval calculating means 24 calculates the door opening waiting time tw and the boarding schedule time interval tint. When there is only one user scheduled to ride in the car 1A, the door opening wait time calculation means 23 and the ride scheduled time interval calculation means 24 are x = y. tw) and the scheduled time of ride (tint) are calculated.

In addition, in the example here, the boarding schedule time interval calculating means 24 calculated the boarding schedule time interval tint as the first index based on the arrival prediction time of the user. However, the boarding schedule time interval calculating means 24 (or the assignment candidate selection index calculation unit 120) of the boarding time registration device 11A of the user y and the boarding call registration device 11A of the user z are used. Based on the operation time, the operation time interval that is the time difference can be calculated, and the calculated operation time interval can be used as the first index instead of the scheduled ride time interval tint. Also in the operation time interval in such a case, the same handling as that in the scheduled ride time interval tint is possible in the arithmetic processing described below.

4-7 is explanatory drawing for demonstrating the relationship of the user arrival prediction time in user x, y, z, and the car arrival prediction time in car 1A. 4 shows the case where the car 1A arrives at the target boarding floor before the user x arrives at the boarding position (the boarding position of the car 1A). FIG. 5 shows a case where the car 1A arrives at the target riding floor after the user x arrives at the riding position and before the user y arrives at the riding position. FIG. 6 shows a case in which the car 1A arrives at the target boarding floor after the user y arrives at the boarding position and before the user z arrives at the boarding position. Fig. 7 shows a case where the car 1A arrives at the target boarding floor after the user z arrives at the boarding position.

As shown in Figs. 4 to 7, the user arrival prediction time HT (x), HT (y), HT (z) and arrival arrival time CarPT (A) of the user in users x, y, and z. ), It is known that the door opening waiting time tw and the scheduled ride time interval tint are changed. That is, by completion of the relationship registration of HT (x), HT (y), HT (z) and CarPT (A), in the calculation process of the door opening waiting time tw and the boarding time interval tint. The object for calculating the difference between HT (z) is determined by any one of HT (x), HT (y), CarPT (A), and 0. In addition, when the operation time interval is used as the first index instead of the scheduled ride time interval tint, it is represented by tint2 in FIG.

Next, the structure of the assignment candidate selection part 130 of the group management apparatus main body 1 is demonstrated. In the previous Fig. 3, the assignment candidate selection unit 130 includes a door opening time corresponding car exclusion means 31, a standby car correspondence exclusion means 32, and an assignment candidate list calculation means (allocation candidate car selection means) 37. Have

The door opening-time correspondence car exclusion means 31 receives the information of the door opening waiting presumption time tw about each of the cars 1A-1D from the door opening waiting presumption time calculation means 23. At the same time, the door opening-time correspondence car excluding means 31 receives information of the scheduled ride time interval tint for each of the cars 1A to 1D from the ride schedule time interval calculation means 24.

Here, assuming that the door opening waiting time tw and the scheduled time interval tint for the assigned car already assigned to the boarding floor corresponding to the boarding call for registration completion are also assigned to the new boarding call. to be. That is, in this case, the door opening waiting time tw and the scheduled ride time interval tint are the values when responding to the boarding call and the new boarding call of registration completion at the same time.

Further, the door opening-time correspondence car exclusion means 31 calculates the following equation (3) for each of the cars 1A to 1D by using the door opening waiting time tw and the scheduled ride time interval tint. Run

&Quot; (3) "

However, each parameter of TW0, TINT0, TWMAX, and TINT1 is as follows.

TW0: standard door opening wait time

TINT0: Standard ride scheduled time interval within standard door open waiting time

TWMAX: maximum door open wait time

TINT1: Standard ride scheduled time interval after the standard door opening wait allowance time elapses The allocation candidate selecting unit 130 also stores in advance the values of the plurality of scheduled ride time intervals including TINT0 and TINT1 as the first allowable value. In addition, the assignment candidate selecting unit 130 previously stores a plurality of door open waiting time values including TW0 and TWMAX as second allowable values.

Then, the door opening-time correspondence car exclusion means 31 determines whether or not the equation (3) is satisfied for each of the cars 1A to 1D (Kamada). As a result, the door opening-time correspondence car exclusion means 31 registers the car number of the car as an assignment candidate in the assignment candidate list for the car that satisfies the expression (3). On the other hand, the door opening time correspondence car exclusion means 31 excludes the car number of the car from the assignment candidate in the assignment candidate list for the car that does not satisfy the expression (3).

The waiting car correspondence exclusion means 32 receives the information of the car arrival prediction time from the car arrival prediction time calculation means 21. In addition, the waiting car correspondence excluding means 32 receives the information of the car arrival predicted time from the user arrival predicted time calculating means 22. In addition, the waiting car correspondence excluding means 32 lists and stores the information of the arrival prediction time of the user in a time series.

The waiting car correspondence excluding means 32 also compares the car arrival prediction time and the user arrival prediction time with respect to a car that is not assigned to the ride floor corresponding to the new boarding call. The waiting car correspondence removing means 32 excludes the car number from the assignment candidate list for the car whose car arrival prediction time is earlier than the user's arrival prediction time by more than the time limit Tb. This time limit Tb is a threshold set in advance in order to suppress the fall of the running efficiency of an elevator group.

The assignment candidate list calculating means 37 selects an assignment candidate from all the cars 1A to 1D by calculating, for example, the following equation (4) with respect to the assignment candidate list.

&Quot; (4) "

However, ALLCAGE: all car number

N31: The car number excluded by the door opening-time correspondence car exclusion means 31

N32: The car number excluded by the waiting car correspondence exclusion means 32

C37: The car number of the assignment candidate car selected by the assignment candidate list calculating means 37

Therefore, by the door opening time correspondence car exclusion means 31 and the standby car correspondence exclusion means 32, cars which do not match the conditions are excluded from the assignment candidate. Then, the assignment candidate list calculation means 37 receives the result of the exclusion processing by the door opening time correspondence car exclusion means 31 and the standby car correspondence exclusion means 32, and allocates the assignment candidate for the new boarding call. 1A ~ 1D) to select them. Further, the assignment candidate list calculating means 37 excludes from the assignment candidate a car that becomes out of service when the boarding layer or the lowering layer of the new boarding call corresponds to the service unavailable layer due to a significant difference or a service cut layer (an irregular layer). do.

Next, the process of excluding an assignment candidate by the door opening time correspondence car exclusion means 31 will be described in detail. 9-12 is explanatory drawing for demonstrating the removal process of the assignment candidate by the car release means 31 corresponding to the door open time of FIG. In addition, in Figs. 9 to 12, the boarding call is registered for both the user x and the user y, and the car 1A can be assigned to the boarding call.

In the case shown in FIG. 9, Equation 3 is established by the door opening waiting time tw for user z being equal to or less than TW0, and the scheduled time interval tint between user z and user y being equal to or less than TINT0. . Accordingly, the door opening-time correspondence car excluding means 31 makes the car 1A an allocation candidate for the new boarding call by the user z.

In addition, in the case shown in Fig. 10, when the scheduled time interval tint between the users z and y is less than or equal to TINT1, the limit value of the door opening waiting time is changed (extended) from TW0 to TWMAX. And the condition of Formula (3) is satisfied by the door opening waiting time tw for user z being TWMAX or less. As a result, the door opening-time correspondence car exclusion means 31 assigns the car 1A to the new boarding call by the user z as in the case shown in Fig. 9.

On the other hand, in the case shown in Fig. 11, since the door opening waiting time tw for the user z is within TW0 and TWMAX, the scheduled time interval of the ride between the user z and the user y exceeds TINT0 and TINT1. The condition of equation (3) does not hold. Accordingly, the door opening-time correspondence car exclusion means 31 excludes the car 1A from the assignment candidate for the new boarding call by the user z.

On the other hand, in the case shown in Fig. 12, the scheduled time intervals for the ride between users z and y are within TINT0 and TINT1, but the scheduled time for opening the door to wait for user z (tw) exceeds TW0 and TWMAX. Therefore, the condition of Equation 3 does not hold. Accordingly, the door opening-time correspondence car exclusion means 31 excludes the car 1A from the allocation candidate for the new boarding call by the user z as shown in FIG.

Next, the operation of the group management apparatus main body 100 will be described. Here, the selection operation of the allocation candidate of the group management apparatus main body 100 (the allocation candidate selection index calculation unit 120 and the allocation candidate selection unit 130) will be described in detail. FIG. 13 is a flowchart showing the operation of the group management apparatus main body 100 of FIG. 3. In FIG. 13, first, when the group management apparatus main body 100 receives a registration request for a new boarding call from any of the remote boarding call registration devices 11A to 11E, any one of all cars 1A to 1D is selected. It selects as evaluation target car (step S101).

And the group management apparatus main body 100 calculates the arrival prediction time to the target boarding floor of the evaluation target car based on the driving situation of the evaluation target car (step S102). In addition, the group management apparatus main body 100 calculates the arrival prediction time to the boarding position corresponding to the evaluation target car for the user who performed the new boarding call operation (step S103).

Then, the group management apparatus main body 100 confirms whether or not the evaluation target car is the assignment completion in the same boarding floor and the destination direction in the boarding floor and the destination direction corresponding to the new boarding call (step S104). When the evaluation target car is not assigned to the same boarding floor and the destination direction in the boarding floor and the destination direction corresponding to the new boarding call (No direction in step S104), the group management apparatus main body 100 is more than the user of the evaluation object car. It is confirmed whether or not to arrive at the boarding floor of the target earlier than the time limit Tb (step S105).

At this time, when the evaluation target car arrives at the boarding floor of the target earlier than the user by the time limit Tb, the group management apparatus main body 100 excludes the flight number of the evaluation target car from the assignment candidate list (step S106). On the other hand, when the evaluation target car does not arrive at the target boarding floor more than the time limit Tb earlier than the user, the group management apparatus main body 100 sets the evaluation target car as the assignment candidate and assigns the breath number of the evaluation target car to the assignment candidate. It adds to a list (step S107).

In addition, when the evaluation target car is assigned to the same boarding floor and destination direction in the boarding floor and destination direction of a new boarding call ("YES" direction in step S104), the group management apparatus main body 100 determines the The door opening waiting time tw at the boarding floor is calculated (step S108). At the same time, the group management apparatus main body 100 calculates a boarding schedule time interval tint of the user who has executed the new boarding call operation and the last user among the plurality of users who have executed the boarding call operation having completed registration (step). S109).

Then, the group management apparatus main body 100 confirms whether or not the calculated door opening waiting time tw and the riding schedule time interval tint satisfy the condition of the expression (3) (step S110). When the door opening waiting time tw and the scheduled ride time interval satisfy the condition of Equation 3, the group management apparatus main body 100 sets the evaluation target car as the assignment candidate, and the breath number of the evaluation target car. Is added to the assignment candidate list (step S107). On the other hand, when the door opening waiting time tw and the scheduled ride time interval tint do not satisfy the condition of Equation 3, the group management apparatus main body 100 excludes the breath number of the car to be evaluated from the assignment candidate list. (Step S106).

After determining whether or not the evaluation target car is to be assigned as a candidate (after steps S106 and S107), the group management apparatus main body 100 confirms whether or not all cars 1A to 1D have been evaluated (step S111). When evaluating all the cars 1A-1D, the selection operation of the assignment candidate by the group management apparatus main body 100 is complete | finished. On the other hand, when not evaluating all the cars 1A-1D, the group management apparatus main body 100 changes the evaluation target car into the unevaluated car (step S112). And the group management apparatus main body 100 calculates the arrival prediction time of the evaluation target car after the change (step S102), and repeats the same operation until evaluation of all the cars 1A-1D is complete | finished.

Through the above operation, the group management apparatus main body 100 refers to the assignment candidate list and determines, as the allocation car, the car whose minimum waiting time is the minimum when the new boarding call is allocated. And the group management apparatus main body 100 sends the information of the allocation number of the allocation car to the remote boarding call registration apparatuses 11A-11E which received the boarding call operation by the user, and assigns the instruction regarding operation | movement of an allocation car. To individual car control devices 2A to 2D.

Next, the car assignment operation by the group management apparatus main body 100 when the general car assignment method is used in the situation where a plurality of users arrives sequentially at the platform 3 in FIG. 1 will be described. . It is explanatory drawing for demonstrating the situation where a some user arrives at the boarding 3 of FIG. In Fig. 14, the remote boarding call registration device 11A is operated by the first user, and the boarding call operation is executed. In contrast, the group management apparatus main body 100 assigns the car 1A to the boarding floor as a response to the boarding call operation of the first user, and registers the boarding call.

Then, after the boarding call operation by the first user, if the boarding call operation is executed by the second or later users in a short time, the group management apparatus main body 100 enters the boarding of the second or more users as shown in FIG. 15. As a response to the call operation, the car 1A assigned first is waited for the door to be opened at the boarding floor. In other words, a plurality of users may be collectively, and only one car 1A may be allocated. In this case, the car 1A, which has been assigned to the boarding call operation of the first user, waits for the door to be opened in the boarding floor until the user is disconnected.

When such an allocation method is used, it is possible to carry a relatively large number of users per one round trip of the car 1A, so that the operating efficiency of the elevator group is relatively high. However, there is a problem that the door opening waiting time of the car 1A becomes long, the waiting time of the user who rides becomes relatively long, and the discomfort of the user increases.

On the other hand, in another general allocation method, if the boarding call operation is executed by the second or more users in a short time after the boarding call operation by the first user, the group management apparatus main body 100 is as shown in Fig. 16. The plurality of users who have performed the flight call operation are divided into a plurality of groups Ga to Gd. And the group management apparatus main body 100 assigns to each of the groups Ga-Gd one by one to the cars 1A-1D. In this case, the waiting time of the user who first boarded the cars 1A to 1D is reduced as compared with the case shown in FIG. However, by having about one to three users riding in one car, the running efficiency of the elevator group is lower than in the case shown in FIG.

That is, when a plurality of users are collectively (as shown in Fig. 15), there is a problem that the waiting time of the user in the car 1A becomes long. On the other hand, when a plurality of users are divided into a plurality of groups (shown in Fig. 16), there is a problem in that many users cannot be transported at once. In order to solve these problems at the same time, it is necessary to appropriately select an allocation car for each user in order to simultaneously suppress the waiting time in the car and to improve the running efficiency of the elevator.

In response to these problems, in the elevator group management apparatus of the first embodiment, the door opening waiting time tw calculated by the allocation candidate selection index calculation unit 120 determines the maximum door opening waiting time TWMAX. If so, the allocation car concerning the boarding call of registration completion is removed by the allocation candidate selector 130 from the allocation candidate regarding the new boarding call. Accordingly, it is possible to improve the operating efficiency of the elevator group by allowing a car different from the assigned car to become an allocation candidate for the new boarding call and suppressing the door open waiting time of the allotted car for the registered boarding call. . In addition, the user's discomfort can be reduced by reducing the waiting time in the car of the user who first arrives at the boarding area.

The door opening time correspondence is based on the door opening waiting time tw and the scheduled time interval tint calculated by the door opening waiting time calculation means 23 and the boarding time interval calculation means 24. The allocation candidate is incorporated by the allocation candidate car exclusion means 31. As a result, the door opening waiting time of the allocation car can be avoided from being longer than necessary. In addition, when there is a user who can ride immediately after the door opening waiting time tw exceeds TW0, the user can ride the door by slightly extending the door opening time.

Moreover, based on the door opening waiting time tw and the boarding scheduled time interval tint calculated by the door opening waiting time calculation means 23 and the ride scheduled time interval calculation means 24, the door opening time correspondence is supported. The allocation candidate is incorporated by the allocation candidate car exclusion means 31. Thereby, since it becomes possible to divide | divide the user to ride appropriately, the running efficiency of an elevator can be improved.

Further, even within the maximum door opening waiting time TWMAX and the standard door opening waiting time TW0, the target car can be excluded from the allocation candidate by the limit value TINT0 of the scheduled ride time interval. Thereby, the avoidance of unpleasant operation | movement, such as the long door opening time of a car or the waiting time in a user's car, and the improvement of the running efficiency of an elevator group can be made compatible.

In addition, when a car arrives at the target boarding floor more than the user by the time limit Tb, the waiting car corresponding exclusion means 32 allows the car to be removed from the allocation candidate, so that the car is waiting for a long time door opening at a boarding floor. Can be avoided, and the running efficiency of the elevator group can be further improved.

In addition, the user arrival prediction time calculating means 22 predicts the arrival time of the user from the remote boarding point registration devices 11A to 11E to the respective boarding positions of the cars 1A to 1D. This configuration makes it possible to freely arrange the hoistway of the car of the elevator group, which is the management target of one group management apparatus main body 100, and the remote boarding call registration device, and greatly improve the degree of freedom of design.

Further, in the first embodiment, the door opening-time correspondence car exclusion means 31 judges whether or not the evaluation target car is to be excluded from the allocation candidate by using the previous equation (3). It is also possible to judge whether or not the evaluation target car is excluded from the allocation candidate by the following equation (5) without the condition.

[Equation 5]

In addition, in 1st Embodiment, it is based on the door opening waiting time tw and the boarding schedule time interval tint from both means of the door opening waiting time calculation means 23 and the boarding schedule time interval calculation means 24. Thus, the process of excluding an assignment candidate by the door opening-time correspondence car exclusion means 31 was executed. With respect to this example, the boarding schedule time interval calculating means 24 is omitted, and the door opening time corresponding car removing means is based on only the door opening waiting time tw from the door opening waiting time calculation means 23. The exclusion process of assignment candidate (31) may be executed. In this way, the door opening waiting time calculation means 23 is omitted, and the door opening time correspondence car exclusion means 31 is only based on the ride scheduled time interval tint from the ride planning time interval calculation means 24. The process of excluding allocation candidates may be performed.

Further, in the first embodiment, the parameters of TW0, TINT0, TWMAX, and TINT1 used in the previous equation (3) are common to all the boarding floors, but the parameter values may be changed in accordance with the boarding floor. For example, in the boarding floor where there are many users boarding, such as a lobby floor, you may make at least 1 parameter of TW0, TINT0, TWMAX, and TINT1 larger than a standard value. In this case, by making the parameter larger, the same car can be collectively boarded in the boarding floor where there are a large number of users who ride the lobby floor or the like.

In addition, in Formula (3) of the first embodiment, the formula is based on two combinations (that is, two parentheses in (3)) for the standard door opening waiting time and the standard ride scheduled time interval. However, the calculation formula used for the calculation process of the door opening-time correspondence car exclusion means 31 is not limited to this example, but is a calculation formula by a combination of three or more for the standard door opening waiting time and the standard ride scheduled time interval. You may use.

Here, for example, in the example shown in Fig. 11 of the first embodiment, after the user y has moved to the riding position {after HT (y)}, the car 1A has arrived at the bottom floor F. In this case, namely, when CarPT (A) exists between HT (y) and HT (z), the calculation time of the door opening waiting time tw is later than the example shown in FIG. For this reason, when the previous door opening time correspondence car exclusion means 31 performs the calculation processing of the previous expression (3) as it is, the standard door opening waiting allowance time TW0 or the maximum door opening waiting allowance time TWMAX. When the user z arrives at the riding position of the car 1A immediately before the end of time, as the calculation time of the door opening waiting time tw is later than the example shown in Fig. 11, the user z is in the car 1A of the user y. Waiting time becomes relatively long.

On the other hand, when the door opening-time correspondence car exclusion means 31 confirms that the boarding schedule time interval tint is larger than the standard boarding schedule time interval TINT0 in the calculation process of the previous expression (3), It may be changed to a small value by the standard door open wait allowance time TW0. In addition, when the door opening time correspondence car exclusion means 31 confirms that the ride scheduled time interval tint is larger than the standard ride scheduled time interval TINT1, the value smaller by the maximum door opening waiting allowance time TWMAX. You may change it to Thereby, when the calculation time of the door opening waiting time tw is later than the arrival time of the boarding position of the car 1A of the car 1A of the user y, the waiting time in the car 1A of the user y is carried out. Can be suppressed.

2nd Embodiment

In 1st Embodiment, the object of management of the group management apparatus main body 100 became the elevator group by which the hoistway was arrange | positioned adjacent to the boarding point 3 in a building. On the other hand, in 2nd Embodiment, as shown in FIG. 17, several board | substrates 3A and 3B are provided in a building. And the object of management of the group management apparatus main body 100 of 2nd Embodiment is an elevator group in which the hoistway was provided adjacent to the board | substrate 3A, 3B. That is, the group management apparatus main body 100 of 2nd Embodiment manages the operation of the elevator group which has the cars 1A-1H in FIG.

Moreover, the moving constant setting part 140 in the group management apparatus main body 100 of 2nd Embodiment adds the car 1E-1H to the information of the boarding position of the cars 1A-1D of each boarding floor. Information of the boarding position of the vehicle is stored in advance. In addition, the assignment candidate selection index calculation unit 120 in the group management apparatus main body 100 of the second embodiment is provided between the boarding position of the cars 1A to 1H and the remote boarding call registration devices 11A to 11E. The distance information is obtained from the moving constant setting unit 140. When the assignment candidate selection index calculation unit 120 receives a request for a new boarding call, the car arrival prediction time for each of the cars 1A to 1H and the respective boarding positions for the cars 1A to 1H are determined. Calculate the user arrival prediction time. Other configurations and operations are the same as in the first embodiment.

In the elevator group management apparatus as described above, even when the elevator is provided in a plurality of parts separated from each other in the building, the same effects as those in the first embodiment can be obtained.

In addition, the number of cars in an elevator group is not limited to the example of 1st and 2nd embodiment, It can determine suitably according to the means, installation environment, etc. of an elevator group.

Third embodiment

In the assignment candidate selection unit 130 of the first embodiment, the door candidate is excluded by the door opening-time corresponding car exclusion means 31 and the standby car correspondence exclusion means 32. On the other hand, in the allocation candidate selection unit 130 of the third embodiment, the allocation candidate exclusion process relating to the new boarding call is executed also in another manner.

It is a block diagram which shows the group management apparatus of the elevator which concerns on 3rd Embodiment of this invention. 18, the individual car control apparatus 2A-2D, the moving constant setting part 140, the allocation car determination part 150, and the operation command part 160 are abbreviate | omitted and shown like FIG. In FIG. 18, the allocation candidate selecting part 130 of 3rd Embodiment is the traffic flow as a full car exclusion means 33, the empty car selection means 34, the car exclusion means 35 just before departure, and the threshold value changing means. The apparatus further includes a corresponding limit value changing means 36 and a selection condition releasing means 38.

When a new boarding call is made, the full house car exclusion means 33 allocates the car 1A-1D which becomes out of service in the boarding floor corresponding to a new boarding call by assigning to another boarding call, and removes it from the allocation candidate. Register on the candidate list. Specifically, the 10,000 won car excluding means 33 executes the registered call in the section between the boarding floor corresponding to the new boarding call and the boarding floor immediately before one of the boarding floors of the new boarding call. Check it. Then, when the car becomes full, by the boarding call registered already, the full car exclusion means 33 excludes the car number from the assignment candidate in the assignment candidate list. That is, the full car exclusion means 33 removes the car from the allocation candidate when the user who has made a new boarding call gets on the car and exceeds the capacity of the car.

The vacant car selecting means 34 registers (adds) to the allocation candidate list as allocation candidates the cars in driving stop, the cars scheduled to stop driving among all cars 1A to 1D, or cars in motion (during dispatch) to a specific floor. do. The car during this driving stop is a car to which the assigned platform call and car call are not set, that is, the car does not have assignment of the platform call and car call. A car scheduled to stop is a car in response to the last set car call, and when all the services are completed after responding to the car call, the car which is in the stopped state, that is, the assignment of the boarding call and the car call, will soon be removed. It is a scheduled car. A car moving to a specific floor is a car moving to wait on a predetermined floor (waiting floor) or the like set in advance according to the operating condition of the elevator group, for example.

When the new boarding call occurs immediately before departure, the car excluding means 35 starts from the same boarding floor as the boarding floor corresponding to the new boarding call among all the cars 1A to 1D in the same direction as the destination direction of the new boarding call. In order to check whether there is a car which has started to close the door. If there is a car that meets the conditions immediately before departure, the car exclusion means 35 excludes the car number from the assignment candidate in the assignment candidate list.

The traffic flow correspondence limit value changing means 36 memorizes the information of the traffic flow in the building in advance (or measures the traffic flow in the building from time to time and prepares the statistics). This traffic flow is information on statistics of changes in the flow of users in the building. Further, the traffic flow response restriction value changing means 36 sets the restriction values in the door opening time response car exclusion means 31 and the standby car correspondence exclusion means 32 in accordance with the change (trend, pattern) of the traffic flow in the building. Dynamically change (or select one of a plurality of limit values stored in advance). The limit value in this door opening-time correspondence car exclusion means 31 is each parameter of TW0, TINT0, TWMAX, and TINT1 used by previous Formula (3). In addition, the restriction | limiting value in waiting car correspondence exclusion means 32 is a time limit Tb.

Here, for example, when the remote boarding call registration device 11A is provided on the lobby floor, and there is a lot of traffic flow from the lobby floor to the upper floor at the time of going to work, the traffic flow corresponding restriction value changing means 36 is TW0. At least one value of TINT0, TWMAX, and TINT1 is changed to a value larger than the value of the traffic flow at normal times.

Examples of this traffic flow include traffic at work, traffic at work and traffic at lunch. The traffic flow at work is a traffic flow with a relatively large number of users moving from the lobby floor to the general floor (than the usual users). In addition, the traffic flow at work is a traffic flow with a lot of users moving from the general floor to the lobby floor. In addition, the traffic flow at lunch is a traffic flow with a lot of users moving from the lobby floor or the restaurant floor to the general floor, and users moving in the reverse direction.

Here, the allocation candidate list calculating means 37 of the third embodiment extracts the allocation candidates from all the cars 1A to 1D by calculating, for example, the following expression (6) with respect to the allocation candidate list.

&Quot; (6) "

However, ALLCAGE: all car number

N31: The car number excluded by the door opening-time correspondence car exclusion means 31

N32: The car number excluded by the waiting car correspondence exclusion means 32

N33: car number excluded by the 10,000 won car excluding means 33

N35: Car number excluded by car exclusion means 35 immediately before departure

C34: the car number selected by the empty car selecting means 34

C37: The car number of the assignment candidate car selected by the assignment candidate list calculating means 37

The selection condition releasing means 38 relaxes the selection condition of the allocation candidates and selects the allocation candidates again when there are no allocation candidates selected by the allocation candidate list calculating means 37. In addition, the selection condition releasing means 38 sets all the cars 1A to 1D as allocation candidates when there are no assignment candidates even after the conditions are relaxed.

Here, the selection method of allocation candidate by the selection condition releasing means 38 is demonstrated concretely. First, the selection method in the case where the new boarding call is not registered with the same boarding floor and the same boarding direction is registered. In this case, the selection condition mitigating means 38 changes the time limit Tb in the waiting car correspondence excluding means 32 to the time limit Tc (where Tb < Tc).

Under such conditions, the selection condition mitigation means 38 executes the same processing as the standby car correspondence exclusion means 32, and the car C32 removed by the standby car correspondence exclusion means 32 for the new boarding call. Determine whether it is assignable or not. As a result, the selection condition mitigating means 38 selects the car excluded by the waiting car correspondence excluding means 32 as an allocation candidate, if there is a car whose car arrival prediction time is about the time limit Tb with respect to the user arrival prediction time. Select.

On the other hand, when there is a boarding call of the same boarding floor and completion of registration in the same boarding direction as the new boarding call, the selection condition mitigating means 38 performs TW0, TINT0, TWMAX and Change the value of TINT1 to a value larger than the previous value.

Under such conditions, the selection condition mitigating means 38 executes the same processing as that of the door opening-time correspondence car excluding means 31, and newly removes the car C31 removed by the door opening-time correspondence car excluding means 31. Determines whether or not allocation is possible for the board call. As a result, if there is a car that satisfies the condition relaxed for the door opening waiting time or the scheduled time interval for the door opening, the selection condition mitigating means 38 selects the car excluded by the car opening means corresponding to the door opening time 31. It selects as an allocation candidate. In addition, another structure is the same as that of 1st Embodiment.

Next, operation | movement of the group management apparatus main body 100 of 3rd Embodiment is demonstrated. Here, the selection operation | movement of the allocation candidate of the group management apparatus main body 100 is demonstrated concretely similarly to previous 1st Embodiment. 19 is a flowchart showing the operation of the group management apparatus main body 100 of FIG. First, when the assignment candidate selecting unit 130 receives a request for registering a new boarding call from any of the remote boarding call registration devices 11A to 11E, it checks the current time and sets each limit value according to the traffic flow corresponding to the current time. (Step S201). That is, the assignment candidate selecting unit 130 changes the values of TW0, TINT0, TINT1, TWMAX, and Tb according to the traffic flow corresponding to the current time.

And the group management apparatus main body 100 selects any one car as evaluation object car among all the cars 1A-1D (step S202). Moreover, when the group management apparatus main body 100 selects the evaluation target car, whether the evaluation target car conforms to the full house exclusion condition, whether the evaluation target car conforms to the exclusion condition immediately before departure, or does it match the empty car selection condition? It confirms, respectively (step S203-205). Here, the evaluation target car is excluded from the full house, the condition immediately before departure and the empty car selection condition are the exclusion processing or selection of the full car exclusion means 33, the immediately preceding car exclusion means 35 and the empty car selection means 34, respectively. Condition corresponding to the processing.

When the evaluation target car does not match any of the full house exclusion condition, the exclusion condition just before departure, and the empty car selection condition, the group management apparatus main body 100 is based on the driving situation of the evaluation target car, The arrival prediction time of is calculated (step S206). In addition, the group management apparatus main body 100 calculates the arrival prediction time to the boarding position corresponding to the evaluation target car for the user who performed the new boarding call operation (step S207).

Then, the group management apparatus main body 100 confirms whether or not the evaluation target car is allotted in the same boarding floor and destination direction as the boarding floor and destination direction corresponding to the new boarding call (step S208). When the evaluation target car is not assigned to the same boarding floor and the destination direction in the boarding floor and the destination direction corresponding to the new boarding call (No direction in step S208), the group management device main body 100 arrives early in the evaluation target car. It is checked whether or not the exclusion conditions are met (step S209). That is, the group management apparatus main body 100 confirms whether the evaluation target car arrives at the target boarding floor more than the time limit Tb earlier than the user.

On the other hand, when the evaluation target car is assigned to the same boarding floor and the destination direction in the boarding floor and the destination direction corresponding to the new boarding call (in the "YES" direction in step S208), the group management apparatus main body 100 determines the value of the car to be evaluated. The door opening waiting time tw in the target boarding floor is calculated (step S210). At the same time, the group management apparatus main body 100 calculates a boarding schedule time interval tint of the user who has executed the new boarding call operation and the user who has executed the registered call processing operation immediately before the new boarding call is made ( Step S211).

And the group management apparatus main body 100 confirms whether the evaluation target car conforms to a door opening waiting removal condition based on the calculated door opening waiting time tw and the boarding schedule time interval tint (step S212). ). That is, the group management apparatus main body 100 confirms whether or not the calculated door opening waiting time tw and the boarding schedule time interval tint satisfy the condition of equation (3).

As a result of these processes, when the evaluation target car meets any one of an early arrival exclusion condition, a full house exclusion condition, an exclusion condition just before departure, and a door open waiting condition exclusion condition ("Step S203, S204, S209, S212" Direction, the group management apparatus main body 100 excludes the breath number of the car to be evaluated from the assignment candidate list (step S213). On the other hand, when the evaluation target car meets the empty car selection condition ("YES" direction in step S205), or when the evaluation target car does not meet the early arrival exclusion condition ("No" direction in step S212), the group management device The main body 100 adds the breath number of the evaluation target car to the allocation candidate list (step S214).

Then, the group management apparatus main body 100 confirms whether or not the number of the car to be evaluated is added to the assignment candidate list or evaluated for all cars 1A to 1D except from the assignment candidate list (step S215). ). At this time, when not evaluating all the cars 1A-1D, the group management apparatus main body 100 changes the evaluation target car into the unevaluated car (step S216). And the group management apparatus main body 100 confirms whether the arrival prediction time of the evaluation target car after the change conforms to a full house exclusion condition (step S203), and when evaluation about all the cars 1A-1D is complete | finished. The same operation (steps S203 to S216) is repeated until now.

Moreover, when evaluating all the cars 1A-1D, the group management apparatus main body 100 confirms whether the car of an assignment candidate exists in an assignment candidate list (step S217). At this time, when there is a car of the allocation candidate in the allocation candidate list, the operation of selecting the allocation candidate by the group management apparatus main body 100 ends.

On the other hand, when there is no car of the allocation candidate in the allocation candidate list (No direction in step S217), the group management apparatus main body 100 relaxes the selection condition and performs reselection processing of the allocation candidate ( S218). Then, as a result of the reselection processing, the group management apparatus main body 100 confirms whether or not a car of the allocation candidate exists in the allocation candidate list (step S219). At this time, when the car of the allocation candidate exists in the allocation candidate list, the selection operation of the allocation candidate by the group management apparatus main body 100 ends.

On the other hand, when there is no car of the assignment candidate in the assignment candidate list (No direction in step S219), the group management apparatus main body 100 sets all the cars 1A to 1D as the assignment candidates and the car (1A). The breath number ˜1D) is registered in the allocation candidate list (step S220). Then, the selection operation of the allocation candidate by the group management apparatus main body 100 ends. In addition, the operation | movement after that is the same as that of 1st Embodiment.

In the elevator group management apparatus as described above, the unavailable car relating to the new boarding call is removed from the allocation candidate by the full car exclusion means 33. Accordingly, when the user who has operated any of the remote boarding point registration devices 11A to 11E arrives at the car's boarding position, the vehicle is first recognized as full and the remote boarding point registration device 11A to 11E is again present. ), You can avoid the unpleasant behavior that must be operated.

In addition, the vacant car selecting means 34 makes it possible to further improve the operating efficiency of the elevator group by allowing the car in charge to be already completed or a car which is completed soon to be selected as the allocation candidate.

Furthermore, the car excluding means 35 immediately before departure departs from the allocation candidate the car which waits long in the boarding floor corresponding to the new boarding call, so that the operating efficiency of the elevator group can be further improved.

In addition, the traffic flow correspondence limit value changing means 36 dynamically changes the limit values for the door opening waiting time and the scheduled ride time interval in accordance with the change in the traffic flow in the building such as when going to work, when leaving work, and during lunch. Accordingly, it is possible to operate the elevator group according to the change of traffic flow, and further improve the operating efficiency of the elevator group.

Furthermore, even if there is no assignment candidate by the normal exclusion process, the selection condition releasing means 38 relaxes the selection condition and secures the assignment candidate. Thereby, malfunction of the group management apparatus main body 100 by the absence of an assignment candidate can be prevented.

In addition, although the selection condition relaxation means 38 performs the same process as the door opening time correspondence car exclusion means 31 after the selection condition relaxation means 38 loosens the selection condition, it is not limited to this example. For example, after the selection condition relaxation means 38 relaxes the selection condition, the door opening time response car exclusion means 31 may be instructed to execute another process under the relaxed conditions. In this way, after the selection condition releasing means 38 relaxes the selection condition, the instruction may be sent to the standby car correspondence excluding means 32 to execute the process again under the relaxed condition.

Fourth embodiment

In the first embodiment, the moving constant setting unit 140 receives the remote boarding call registration devices 11A to 11E that have received the new boarding call operation, and the boarding positions of all the cars 1A to 1D corresponding to the new boarding call. The movement distance information and the standard movement speed information were sent to the assignment candidate selection index calculation unit 120. In contrast, in the fourth embodiment, the moving constant setting unit 140 sends the information regarding the user's moving time to the assignment candidate selection index calculation unit 120 in more detail.

In addition, in 1st Embodiment, although the remote boarding call registration apparatus 11A-11E was arrange | positioned in one place in each boarding floor of a building, in 4th Embodiment, the remote boarding call registration apparatus 11A-11E is building. It is arrange | positioned in multiple places in each boarding floor of the. The plurality of locations on each floor of the building are, for example, entrances and exits of a plurality of living rooms, a plurality of tenant compartments, or a plurality of office compartments.

Moreover, the operation part of the remote boarding point call registration apparatus 11A-11E of 4th Embodiment is a some attribute identification button (for example, a wheelchair drive button: illustration) for identifying the user's attribute regarding a healthy person or a physically handicapped person. Not). In addition, when the remote boarding call registration apparatuses 11A to 11E receive a new boarding call operation, the group management device main body 100 receives information on the attribute corresponding to the operated attribute identification button together with the registration request for the new boarding call. Send to

It is a block diagram which shows the group management apparatus of the elevator which concerns on 4th Embodiment of this invention. In addition, in FIG. 20, the assignment candidate selection part 130, the assignment car determination part 150, the operation command part 160, and individual car control apparatus 2A-2D are abbreviate | omitted and shown. In FIG. 20, the movement constant setting part 140 has the movement distance setting means 41, the movement speed setting means 42, and the movement speed fall parameter setting means 43. As shown in FIG.

The movement distance setting means 41 is a movement distance (walking distance) between the remote boarding point registration devices 11A to 11E disposed at plural places of the building and the boarding positions of the cars 1A to 1D for each boarding floor. Is stored as moving distance information. Further, when the movement distance setting means 41 receives the new boarding call registration request from any of the remote boarding call registration devices 11A to 11E, the remote boarding call registration devices 11A to 11E that generated the registration request; The moving distance information between the boarding positions of all the cars 1A-1D is extracted. Then, the movement distance setting means 41 sends the extracted movement distance information to the assignment candidate selection index calculation unit 120 ((user arrival prediction time calculation means 22)).

The movement speed setting means 42 stores in advance the information of the plurality of user movement speeds in correspondence with the information of the user's attributes regarding the health person and the physically handicapped person. The movement speed corresponding to a healthy person (general user) is 1.0 m / sec, for example, and the movement speed corresponding to a physically disabled person is 0.7 m / sec, for example. In addition, the movement speed setting means 42 extracts the movement speed corresponding to an attribute of a user, when receiving the attribute identification information from the remote boarding point registration devices 11A-11E.

The movement speed reduction parameter setting means 43 memorizes the information of the traffic flow in the building in advance (or measures the traffic flow in the building at any time and prepares the statistics). In addition, when the movement speed reduction parameter setting means 43 receives the new boarding call registration request from any of the remote boarding call registration devices 11A to 11E, it corresponds to the current time in the boarding floor where a new boarding call operation occurred. With reference to the traffic flow, the movement speed reduction parameter is set.

Specifically, the movement speed decrease parameter setting means 43 is 1.0 based on the degree of congestion by the user getting on and off in the boarding floor where the new boarding call operation is generated, the size of the boarding 3, and the shape of the boarding 3. Set the movement speed reduction parameter below. Then, the moving speed decreasing parameter setting means 43 sends the information of the set moving speed decreasing parameter to the moving speed setting means 42.

When the movement speed setting means 42 receives the information of the movement speed decrease parameter from the movement speed decrease parameter setting means 43, it assigns a value that can be obtained by relying on the movement speed of the user as the movement speed information. It sends to the selection index calculation part 120 (user arrival prediction time calculation means 22). The assignment candidate selection index calculation unit 120 calculates the user arrival prediction time based on the movement distance information and the movement speed information. That is, the movement distance, the movement speed of the user, and the movement speed decrease parameter set by the movement constant setting unit 140 are used in the calculation process of the user arrival prediction time. The other structure is the same as that of 1st embodiment or 3rd embodiment.

Next, the operation of the group management apparatus main body 100 of the fourth embodiment will be described. Here, the setting operation | movement of the moving constant of the group management apparatus main body 100 is demonstrated concretely. FIG. 21 is a flowchart showing the operation of the group management apparatus main body 100 of FIG. 20. First, when the group management apparatus main body 100 receives a boarding call registration request from the remote boarding call registration devices 11A to 11E, the remote boarding call registration devices 11A to 11E that generated the registration request, and the target boarding floor. The moving distance of a user is set by the positional relationship of the ride positions of all the cars in step (step S301).

Further, the group management apparatus main body 100 sets the movement speed reduction parameter based on the degree of congestion of the ride floor based on the traffic flow corresponding to the current time (step S302). And the group management apparatus main body 100 sets a movement speed based on a movement speed and a movement speed fall parameter according to a user's attribute (step S303).

Then, the group management apparatus main body 100 calculates a user arrival prediction time based on the set moving distance and moving speed (step S304). Thereby, the operation | movement at the time of setting the moving constant by the group management apparatus main body 100 is complete | finished. Other operations are the same as in the first embodiment or the third embodiment.

The group management apparatus of the above-mentioned elevator is moved to the boarding position of all the cars 1A-1D from the remote boarding call registration apparatus arrange | positioned in each of several places in each boarding floor of the building by the movement distance setting means 41. FIG. The moving distance of is extracted. By this structure, it becomes possible to provide remote boarding point call registration apparatus 11A-11E in the several part in each boarding floor of a building. At the same time, it is possible to provide an elevator hoisting path in various places instead of the specific landing area. By this, under the management of the group management apparatus main body 100, the arrangement | positioning of the remote boarding call registration apparatus 11A-11E and the arrangement | positioning of the elevator way can be designed freely.

In addition, since the moving speed setting means 42 sets the moving speed in accordance with the attributes relating to the health person and the physically handicapped person of the user, it is possible to avoid losing the user's car and arriving at the car's riding position earlier than expected. have.

Furthermore, since the moving speed decrease parameter setting means 43 sets the moving speed according to the congestion of the boarding point, it is possible to avoid the unpleasant work that the user cannot ride the assigned car at the time of the boarding congestion.

In addition, in 4th Embodiment, the distance between each boarding position of all the cars 1A-1D, and the installation location of remote boarding point registration apparatus 11A-11E is used as the moving distance in the movement distance setting means 41. As shown in FIG. I remembered. In this example, when a part or all of the car's boarding positions are arranged concentrated in one boarding area, the distance between the representative point such as the center of the boarding station and the remote boarding call registration devices 11A to 11E is moved. The moving distance setting means 41 may also store the data.

In addition, although the moving speed setting means 42 set the moving speed of a user based on the information of the attribute regarding the health person and the physically disabled of the user who performed the new boarding call operation in 4th Embodiment, it is limited to this example. It is not. For example, you may set the moving speed of a user based on the information of the attribute regarding whether a user is accompanied by a pet (dog etc.). Moreover, you may set arbitrary moving speeds for every user.

5th embodiment

In the first embodiment, the allocation car determination unit 150 selects a car whose increase in the total waiting time is minimum when the allocation car determination unit 150 allocates to the boarding floor corresponding to the new boarding call from the allocation candidate list, and determines the car as the allocation car. did. In contrast, in the fifth embodiment, the allocation car determination unit 150 determines the allocation car from the allocation candidate list based on other criteria.

It is a block diagram which shows the group management apparatus of the elevator which concerns on 5th Embodiment of this invention. In addition, in FIG. 22, the assignment candidate selection index calculation part 120, the moving constant setting part 140, the remote boarding point call registration apparatus 11A-11E, and the individual car control apparatus 2A-2D are abbreviate | omitted and shown. In Fig. 22, the assigned car determining unit 150 includes the same car assignment determining means 51, the assigned car selecting means 52, the assigned car assign determining means 53, and the unassigned car selecting means. (54), the waiting time evaluation index car allocation determination means 55, and the predetermined stop number limit value relaxation means 56.

The boarding floor destination floor same car assignment determination means 51 receives the car number of at least one assignment candidate car from the assignment candidate list calculation means 37 or the selection condition releasing means 38. When the boarding floor destination floor same-car allocation determination means 51 receives the car number of the car of several assignment candidates, it confirms whether the car which is going to be stopped exists in the boarding floor and destination floor (lower floor) corresponding to a new boarding call. do.

And if the boarding floor destination floor same car allocation determination means 51 has a car scheduled to stop in the boarding floor and the destination floor corresponding to a new boarding call, it determines that car as an allocation car regarding a new boarding call. In addition, when there are a plurality of cars scheduled to be stopped in the boarding floor and the destination floor corresponding to the new boarding call, the boarding floor destination floor same car assignment determining means 51 randomly selects one car or corresponds to the new boarding call. Choose the car that is expected to arrive early on the boarding floor. Then, the ride floor destination floor same car assignment determination means 51 determines the selected car as the assignment car. In addition, when the boarding floor destination floor same-car allocation determination means 51 determines an assigned car, it transmits the information of the breathing number of the assigned car to the driving command part 160. FIG.

The car assignment means 52 selects in advance the initial value of the predetermined stop limit value Nstop. The initial value of this predetermined stop number limit value Nstop is determined by the following equation (7), for example.

[Equation 7]

(Nstop initial value) = 2 x (stoppable floors in the direction of the new boarding call) / (total number of cars)

In addition, when the allocation car is not determined by the boarding floor destination floor same-car allocation determination means 51, the base allocation car selection means 52 performs a selection process of allocation car. The base assignment car selection means 52 is going to drive in the boarding floor and the destination direction corresponding to the new boarding call, and the scheduled stop count in the registration direction of the new boarding call after allocating the new boarding call is the predetermined stop limit value Nstop. It is confirmed whether the following cars exist among the allocation candidates. If even one of the cars exists, the assignment car selection means 52 selects the car from the assignment candidate, and sends the car number information to the assignment car assignment determination means 53.

The assigned car assignment determining means 53 determines the car selected by the assigned car selection means 52 as the assigned car. Here, when the assigned car assignment determination means 53 receives a plurality of car's flight numbers from the assigned car selection means 52, the car arrival prediction time in the boarding floor corresponding to the new boarding call and the new boarding pass The car whose minimum absolute value of the difference of the user arrival prediction time of a call is minimum is determined as allocation car. In addition, when the assignment car assignment determination means 53 determines the assignment car, it transmits the information of the breathing number of the assignment car to the driving command part 160. FIG.

The unassigned car selecting means 54 stores the initial value of the predetermined stop limit value Nstop in advance, similarly to the preassigned car selecting means 52. Further, the unassigned car selecting means 54 executes the process of selecting an assigned car when the assigned car is not selected by the preassigned car selecting means 52.

Furthermore, the unassigned car selecting means 54 is not going to drive in the boarding floor and the destination direction corresponding to the new boarding call, and the scheduled stop number is not the scheduled stop number limit value in the registration direction of the new boarding call after allocating the new boarding call. (Nstop) Checks whether the following cars exist among the allocation candidates. If there is even one of the cars, the unassigned car selecting means 54 selects the car from the allocation candidate, and sends the information of the car number to the waiting time evaluation index car allocation determining means 55.

The waiting time evaluation indicator car assignment determination means 55 determines the car selected by the unassigned car selection means 54 as the assignment car. Here, when the waiting time evaluation indicator car assignment determination means 55 receives a plurality of pieces of car number from the unassigned car selection means 54, it executes arithmetic processing relating to driving schedules of all of those cars.

Specifically, the waiting time evaluation index car allocation determining means 55 calculates the car arrival prediction time of each boarding call stop floor of each car for each case before allocating a new boarding call and after assigning a new boarding call. do. Then, the waiting time evaluation index car assignment determining means 55 is based on the car arrival prediction time of each boarding stop floor of each car and the user arrival prediction time of the user scheduled to ride on each car in each boarding stop floor. Then, the calculation shown in the following expression (8) is performed.

[Equation 8]

However, WVal _bef (k): Index for evaluating waiting time of car (k) before allocating new boarding call.

WVal _aft (k): Index of waiting time of car (k) after allocation for new boarding call

CarPT _k (f, d): Arrival prediction time of car (k) in boarding floor (f) direction (d)

PSGPT _k (f, d, j): User to boarding position of car (k) about jth user among the users who are going to board the car (k) in boarding floor (f) and direction (d). Arrival prediction time

wt _k (f, d, j): Waiting time for car (k) of user j

Twt _k (f, d): Maximum waiting time value in the boarding layer f and direction d of car k

HallCall (k): set of registered boarding call in car (k)

α: parameter with standard value 1.0

Thereby, the waiting time evaluation index car allocation determination means 55 sets the waiting time evaluation index WVal (k), i.e., WVal _bef (k) for each case before and after assigning the car k to the new boarding call. And WVal _aft (k). Then, the waiting time evaluation index car assignment determining means 55 calculates WVal _aft (k)-WVal _bef (k) which is the difference between WVal _aft (k) and WVal _bef (k). As a result, the waiting time evaluation index car allocation determination means 55 determines the minimum car as the allocation car by WVal _aft (k)-WVal _bef (k). In addition, when the waiting time evaluation index car assignment determination means 55 determines the assignment car, it transmits the information of the breathing number of the allocation car to the driving command unit 160.

The predetermined stop count limit value mitigating means 56 increases the predetermined stop count limit value Nstop by one unit when the assigned car is not selected by the unassigned car selecting means 54. That is, the predetermined stop number limit value mitigating means 56 relaxes the condition regarding the predetermined stop number as Nstop = Nstop + 1.

Then, after the predetermined stop number limit value mitigating means 56 relaxes the condition relating to the predetermined stop number, under the conditions, the assigned car selection means 52 and the unassigned car selection means 54 execute the selection car selection process. do. Until the assigned car is finally determined, the predetermined stop limit value mitigating means 56 continues to relax the condition regarding the scheduled stop, so that the assigned car selecting means 52 and the unassigned car selecting means 54 select the assigned car. Repeat the process. The other configuration is the same as any of the first to fourth embodiments.

Next, operation | movement of the group management apparatus main body 100 of 5th Embodiment is demonstrated. Here, the operation of determining the allocation car of the group management apparatus main body 100 will be described in detail. FIG. 23 is a flowchart showing the operation of the group management apparatus main body 100 of FIG. In FIG. 23, the group management apparatus main body 100 first confirms whether or not a car scheduled to stop exists in the assignment candidate list in the boarding floor and the destination floor (lower floor) corresponding to the new boarding call (step S401).

When the scheduled cars exist in the assignment candidate list in the boarding floor and the destination floor corresponding to the new boarding call, the group management apparatus main body 100 confirms whether or not the corresponding cars are plural (step S402). At this time, when the number of cars concerned is singular, the group management apparatus main body 100 determines that car as the allocation car (step S403), and terminates the determination operation of the allocation car.

On the other hand, when there are a plurality of cars (Yes direction in step S402), the group management apparatus main body 100 selects one car at random from a plurality of cars (step S404). Then, the group management apparatus main body 100 determines the selected car as an allotted car (step S403), and ends the determination operation of the allotted car.

Further, when no scheduled cars are present in the assignment candidate list in the boarding floor and the destination floor corresponding to the new boarding call (No direction in step S401), the group management apparatus main body 100 corresponds to the new boarding call. It is confirmed whether or not cars scheduled to be driven in the ride floor and the destination direction exist in the allocation candidate list (step S405). At this time, when the car scheduled to drive in the boarding floor corresponding to the new boarding call and in the destination direction exists in the assignment candidate list, the group management apparatus main body 100 meets the car assignment assignment list that satisfies the condition regarding the predetermined stop limit value Nstop. It is confirmed whether or not there exists (step S406).

If a car meeting the condition regarding the predetermined stop limit value Nstop exists in the allocation candidate list (YES direction in step S406), the group management apparatus main body 100 checks whether or not the corresponding car is plural (step S407). . At this time, when the number of cars concerned is singular, the group management apparatus main body 100 determines that car as the allocation car (step S403), and terminates the determination operation of the allocation car.

On the other hand, when there are more than one car (the "YES" direction in step S407), the group management apparatus main body 100 selects the car whose absolute value of the difference between the car arrival prediction time and the user arrival prediction time is the minimum (step S408). . Then, the group management apparatus main body 100 determines the selected car as the allocation car (step S403), and ends the determination operation of the allocation car.

Furthermore, when the car scheduled to drive in the boarding floor and the destination direction corresponding to the new boarding call does not exist in the assignment candidate list (No direction in step S405), the group management apparatus main body 100 sets the predetermined stop limit value Nstop. It is checked whether or not a car meeting the condition relating to the present exists in the assignment candidate list (step S409).

If a car meeting the condition regarding the predetermined stop number limit value Nstop exists in the allocation candidate list (YES direction in step S409), the group management apparatus main body 100 confirms whether or not the corresponding car is plural (step S410). . At this time, when the number of cars concerned is singular, the group management apparatus main body 100 determines that car as the allocation car (step S403), and terminates the determination operation of the allocation car.

On the other hand, when there are more than one car (the "YES" direction in step S410), the group management apparatus main body 100 performs the operation shown in the previous expression (8), and selects the car having the minimum waiting time evaluation index (step) S411). Then, the group management apparatus main body 100 determines the selected car as the allocation car (step S403), and ends the determination operation of the allocation car.

Here, when no car matching the condition regarding the scheduled stop limit value Nstop exists in the assignment candidate list (No direction in step S406 or S409), the group management apparatus main body 100 sets the predetermined stop limit value Nstop. Is set to Nstop + 1 (step S412). Then, the group management apparatus main body 100 confirms whether or not the car scheduled to drive in the boarding floor and the destination direction corresponding to the new boarding call exists in the allocation candidate list (step S405), and the same until the allocation car is finally selected. Repeat the operation. The other operation is the same as that of the first to fourth embodiments.

In the above-described elevator group management apparatus, the assigned car selecting means 52 and the unassigned car selecting means 54 determine the assigned car using the predetermined stop limit value, thereby suppressing the stop number of the car and Ambient time of 1A-1D can be shortened, and the running efficiency of an elevator group can be improved.

In addition, when a plurality of assignment candidates are selected by the unassigned car selection means 54, the wait time evaluation index car assignment determination means 55 determines the assigned car by the wait time evaluation index in consideration of the user's moving time. do. As a result, the evaluation according to the waiting time from the user's arrival at the riding position of the car can be performed, and a more accurate allocation car can be determined.

A car and a user are more than necessary by causing the car assignment user 53 determining means 53 to determine a car in which the square (absolute value) of the difference between the car arrival prediction time and the user fall-off prediction time is minimized. Waiting at the boarding station can be avoided and the running efficiency of the elevator group can be further improved.

In addition, in 5th Embodiment, the allocation car was selected based on the planned stop number limit value previously memorize | stored by the pre-assigned car selection means 52 and the unassigned car selection means 54. In FIG. Not limited to this example, the assigned car selecting means 52 and the unassigned car selecting means 54 may select the assigned car using the predetermined stop limit value according to the traffic flow or the boarding floor of the boarding call.

In addition, in the fifth embodiment, the base allocation car assignment determination unit 53 selects a car having an absolute value of the difference between the car arrival prediction time and the user arrival prediction time as the minimum allocation car. For this example, the car arrival prediction time {CarPTk (f, d)} and the user arrival prediction time PsgPT _k (f, d) in the flight floor f and the direction d as shown in the following equation (9). ), The base allocation car assignment determination means 53 may select the allocation car. Β in the following expression (9) is a parameter of standard value 1.0.

[Equation 9]

Furthermore, in the fifth embodiment, in the waiting time evaluation index car assignment determination means 55, the standard value of α in the previous expression (8) was set to 1.0, but the role of the new boarding call generation layer such as the lobby layer and the general layer, You may change the value of α depending on the traffic flow such as when you go to work, after work, or during lunch. For example, in a congestion boarding floor such as a doorway at work, α may be changed to a value smaller than a standard value of about 0.5.

In addition, although the allocation car was determined by the waiting time evaluation index car allocation determining means 55 based on the next of the waiting time evaluation index {WVal _aft (k)} before and after allocation, for example, the index indicating the car congestion degree. The allocation car may be determined by the multipurpose evaluation index that combines the other indexes and the waiting time evaluation index.

Furthermore, in the waiting time evaluation index car allocation determination means 55, the sum of calculations for each of the boarding floors and the respective travel directions was used as the waiting time evaluation index, but the square of the difference between the car arrival prediction time and the user arrival prediction time Calculation may be performed for each user, and the sum for each user may be a waiting time evaluation index.

In addition, in the waiting time evaluation index car allocation determination means 55, the sum of the square layers and the angular direction of the square of the difference between the car arrival prediction time and the user arrival prediction time was used as the waiting time evaluation index. The sum of the squares of the time may be used as a wait time evaluation index.

6th embodiment

In 1st Embodiment, individual car control apparatuses 2A-2D mainly made the door opening and closing control of the car 1A-1D, respectively. In contrast, in the sixth embodiment, the group management apparatus main body 100 generates a door opening and closing instruction, and the individual car control apparatuses 2A to 2D open and close the doors of the cars 1A to 1D based on the door opening and closing instruction. Take control. That is, in 6th Embodiment, the group management apparatus main body 100 becomes a main body and performs door opening / closing control of the cars 1A-1D.

It is a block diagram which shows the group management apparatus of the elevator which concerns on 6th Embodiment of this invention. In addition, in FIG. 24, the allocation candidate selection part 130 and the moving constant setting part 140 are abbreviate | omitted and shown. In FIG. 24, the driving command unit 160 includes a boarding schedule user list storage unit 61 and a door opening / closing command unit 62.

When the new boarding call is generated, the boarding schedule user list storing means 61 receives information of the user arrival prediction time in the user who has executed the new boarding call operation from the assignment candidate selection index calculation unit 120. At the same time, the boarding schedule user list storage means 61 receives information from the assigned car determination unit 150 of the assigned car number determined for the new boarding call.

Further, the boarding schedule user list storage means 61 associates the information of the user arrival prediction time received from the allocation candidate selection index calculation unit 120 with the information of the assigned car number received from the allocation car determination unit 150, and the like. It stores as a boarding schedule user list. In addition, after the assigned car arrives (services) at the boarding floor corresponding to the boarding call and departs from the boarding floor, the boarding schedule user list storage means 61 stores the information of the user arrival predicted time associated with each other and the unit number of the assigned car. The combination of the information is deleted from the ride schedule user list.

When the door opening / closing command means 62 arrives at the boarding floor corresponding to the boarding call as one of the cars 1A to 1D as a response to the boarding call, the boarding schedule user list storage means 61 stores the boarding. The door opening / closing instruction is generated based on the planned user list. In addition, the door open / close command means 62 sends the generated door open / close command to the individual car control devices 2A to 2D corresponding to the car arriving at the boarding floor. That is, the door opening and closing instruction means 62 controls the door opening and closing of the car via the individual car control devices 2A to 2D.

Specifically, the door opening and closing command means 62 performs the following calculation (10) on the cars 1A to 1D arriving at the boarding floor corresponding to the boarding call based on the boarding schedule user list.

[Equation 10]

(Last User Arrival Estimated Time in Ride in User List)-(Current Time)

That is, the door opening-and-closing command means 62 refers to the boarding schedule user list of the user who is going to board the assigned car in the designated direction on the target boarding floor, and the user arrival prediction time regarding the last user of the boarding plan user list. Compare the current time. If the value of the comparison result is large for a certain time or more, the door opening / closing command means 62 continues to open the door of the target car until the last user's scheduled ride time is reached. Sends the door open continuation instruction to the car control devices 2A to 2D. At the same time, the door opening and closing command means 62 monitors the difference between the user arrival prediction time and the current time for the last user even when the door opening of the target car is continued.

When the value of the comparison result of the equation (10) becomes less than a certain time, the door opening and closing command means (62) continues to open the door so as to continue opening the door only for a predetermined time, for example, a standard door opening duration of about 4 seconds. A command is sent to the door open continuation command to the individual car control devices 2A to 2D corresponding to the car. And the door opening-and-closing command means 62 sends a door closing start instruction | command immediately to the individual car control apparatus 2A-2D corresponding to a car after the door opening duration time elapses.

The door opening / closing command means 62 executes the following formula (11) for the cars 1A to 1D arriving at the boarding floor corresponding to the boarding call based on the boarding schedule user list.

[Equation 11]

(Estimated time of arrival of the first user in the list of scheduled users)-(Current time)

That is, the door opening-and-closing command means 62 refers to the boarding schedule user list of the user who is going to board the assigned car in the designated direction on the target boarding floor, and the user arrival prediction time regarding the first user of the boarding plan user list. Compare the current time. When the value of the comparison result is large for a predetermined time or more, the door opening / closing command means 62 responds to the car so that the door opening of the assigned car is completed at the user arrival prediction time in the first user. The door opening start instruction is sent to the individual car control devices 2A to 2D. On the other hand, when the value of the comparison result of the expression (11) is less than a predetermined time, the door opening / closing command means 62 receives the door opening start instruction immediately corresponding to the car 2A after the car arrives at the boarding floor. ~ 2D).

Therefore, the door opening and closing instruction means 62 generates the door opening and closing instruction of the target car based on the user arrival prediction time for the first user or the user arrival prediction time for the last user in the riding schedule user list. do. The other structure is the same as that of any of the first to fifth embodiments.

Next, operation | movement of the group management apparatus main body 100 of 6th Embodiment is demonstrated. Here, the operation of generating the door opening continuation instruction and the door closing start instruction of the group management apparatus main body 100 will be described. 25 is a flowchart showing the operation of the group management apparatus main body 100 of FIG. In FIG. 25, when a new boarding call is generated and the allocation car is determined as a response to the new boarding call, the group management apparatus main body 100 assigns a user arrival prediction time to the user who has executed the new boarding call operation. We associate with and store in boarding schedule user list. And when a new boarding call generate | occur | produces and an allocation car is determined as a response of the new boarding call, the group management apparatus main body 100 updates a boarding schedule user list from time to time (step S501).

When the allocation car arrives at the boarding floor corresponding to the boarding call for registration completion, the group management apparatus main body 100 compares the current arrival time with the user arrival prediction time for the last user in the boarding schedule user list (step S502). ). Then, the group management apparatus main body 100 confirms whether the user arrival prediction time is slower than the current time by a predetermined time or more (step S503).

If the user arrival prediction time is slower than the current time by a certain time or more, the group management apparatus main body 100 generates a door open continuation command (step S504), and controls the individual car corresponding to the assigned car to the door open continuation command. Send to device 2A ~ 2D. At this time, the group management apparatus main body 100 continues the door opening continuation instruction to the individual car control apparatuses 2A to 2D corresponding to the target allocation car until the user arrival prediction time is less than a certain time from the current time. And the target allocation car is waited for the door to be opened.

On the other hand, if the user arrival prediction time is less than a certain time from the current time, the group management apparatus main body 100 issues the door opening continuation instruction corresponding to the car so that the target allocation car continues to open the door only by the door opening duration time. Sends the door open continuation instruction to the car control devices 2A to 2D. Then, when the door opening duration time elapses, the group management device main body 100 generates a door closing start instruction (step S505), and starts closing the door to the individual car control devices 2A to 2D corresponding to the assigned car. Send a command and close the target car. Thereby, the operation | movement generation | generation operation of the door opening continuation instruction and the door closing start instruction by the group management apparatus main body 100 complete | finishes.
