  In a relatively large building, a plurality of elevators are installed in order to improve the elevator transportation capacity, and a system for selecting and servicing the optimal car at the time of call registration at the landing site is introduced. Furthermore, as the scale of a building increases, the number of elevators installed increases, and a plurality of elevators are appropriately controlled by a group management device to improve services such as reducing waiting time for users.

  In such a group management elevator apparatus, various systems have been proposed in, for example, Japanese Patent Laid-Open No. 62-79173 (Patent Document 1), Japanese Patent Application Laid-Open No. 2009-2105040 (Patent Document 2), and the like.

  In Patent Document 1, the generation of past hall calls, the information on getting on and off the car and the destination information on the car are learned according to each traffic mode of the building and used as a macro traffic flow. Collect and use data related to the transition of buildings and current data as a micro traffic flow, and obtain and model demand forecasts for concentration and divergence of each floor considering the direction from the demand forecast of each traffic flow. Describes a group management control method for an elevator in which a tendency of a transitional flow is extracted and group management control adapted to this tendency is performed.

  According to this, in addition to macro changes in traffic flow, micro changes are accurately captured, traffic demand is predicted and modeled, group management control corresponding to that model is executed in a timely manner, and at times of low demand As a matter of course, it is possible to improve the transportation capacity comprehensively as a system even during high demand.

  Further, in Patent Document 2, paying attention to the fact that the required door opening / closing time is determined by the user's getting on / off time with respect to the car at each service stop floor, the getting on / off time is predicted, and the door is opened by this predicted getting on / off time. In order to adjust the time, the elevator control system with door opening / closing control means that automatically closes when the car passes a predetermined time after the door is opened. There is described an elevator door control system that includes means for calculating a predicted getting-on / off time at that floor, and that adjusts the time length of the door opening / closing control means in accordance with the calculated estimated getting-on / off time.

  According to this, it is possible to automatically set the door opening time in consideration of the safety of passengers and passengers, and it is possible to improve the transport capacity, and the change of the door opening time is not limited to the calling conditions. Appropriate door opening time can be set at the service stop floor, and transportation capacity (for example, the number of people that can be transported per hour) can be improved.

  By the way, the group management elevator apparatus described in Patent Document 1 and Patent Document 2 causes an extremely long wait to the user when the user who is waiting at the landing is predicted to be congested in the near future. No consideration has been given to improving transport capacity without generating it.

  Patent Document 1 describes shortening the lap time, but simply shortening the lap time causes a phenomenon that the car departs with a small number of passengers, thereby eliminating congestion. There was a problem that the transport amount could not be reduced. In addition, as shown in Patent Document 2, simply adjusting the door opening time to shorten the stop time causes a useless stop time, which also causes a problem that the transport amount decreases. . From such a background, it is required to improve the transportation capacity without causing an extremely long waiting time for the user at the landing when the future congestion is predicted.

  An object of the present invention is to provide a novel group management elevator capable of improving the transportation capacity of a user by suppressing the occurrence of a long wait for a user at a landing when a future congestion is predicted. It is an object of the present invention to provide a method for assigning boarding cars by means of device and group management.

However, the present invention is not limited to the following embodiments, and various modifications and application examples are included in the technical concept of the present invention. Is included in the range.

  Recently, office buildings have become large-scale, and the elevator devices of this office building are also being managed in groups. In this office building, an ID authentication code, which is personal identification information, is assigned to the user from the viewpoint of security management. For example, an ID authentication code is stored in an IC card, and the ID authentication code is read wirelessly or by a touch sensor.

  Therefore, in the group management elevator device, it is possible to grasp from the read ID authentication code that the user comes to the elevator platform, so the waiting time is shortened by assigning a car to the lobby floor in advance and waiting. A system has been proposed. Such a system is basically intended to shorten the waiting time by waiting for a car on the lobby floor during work hours when there are many people going in and out. This embodiment has been made against the background of such a system.

  FIG. 1 is a configuration diagram showing a main part of a group management elevator apparatus according to an embodiment of the present invention. The group management elevator apparatus includes a plurality of elevator boarding machines 1A to 1N, boarding machine control means 2A to 2N for controlling the boarding machines 1A to 1N, and personal identification information media such as an ID card possessed by the user.

Here, the user management means 6 and the group management control means 7 are collectively referred to as group management means GM.

  In the present embodiment, the service floors that serve each of the elevator cars 1A to 1N of the plurality of elevators are set, for example, the passenger cars that go straight to the top floor, and go straight to the middle floor Thereafter, there are set a boarding machine that stops on each floor, a boarding machine that stops on all floors, a boarding machine that stops on floors up to a predetermined floor, and the like.

  The plurality of building arrival detection means 3 arranged at the entrances and exits of the building where the elevator is installed detect both the arrival of the user at the building and the personal identification information of the user before arriving at the landing. . The landing arrival detection means 4 is arranged at a landing closer to the elevator entrance than the building arrival detection means 3, and detects that the user has arrived at the landing.

  The notification means 5 is arranged in the vicinity of the landing arrival detection means 4 and provides guidance on the changed assigned boarding number to a user who is determined to change the boarding number to be boarded. The notification means 5 can employ a notification method using a display screen, a notification method using sound such as a speaker, or a combination of these.

  The user management means 6 captures the information detected by each building arrival detection means 3 to detect the arrival of each user at each doorway, and also captures the information detected by the landing arrival detection means 4. An arrival detection unit 8 is provided for detecting that a user has arrived at the landing.

  In addition, a user information management unit 9 that manages the arrival time of the user's landing in the building, an operation information management unit 10 that manages current and future operation information of each of the boarding stations 1A to 1N, and the current building The arrival time calculation unit 11 that calculates the arrival time of each user using the congestion status and the past use history, and the detected arrival time of the user and the operation information of each of the cars 1A to 1N are used. It has the user grouping formation part 12 which groups a user in the condition where congestion is anticipated, and the operation information notification part 13 which alert | reports from the alerting | reporting means 4. FIG.

  The group management control means 7 provisionally assigns the user information management unit 14 for managing the detected user information in the group, and temporarily assigns each car number to each group, and calculates the arrival time of each car number. By adjusting the arrival time of each boarding unit according to part 15 and each boarding car according to the destination floor and door opening / closing time, the transport capacity will be enhanced and the number of long waiting people will be reduced An allocation evaluation unit 16 that determines allocation, an operation information determination unit 17 that determines operation information of each boarding car, and an operation information management unit 18 that manages current and future driving information of each boarding car 1A to 1N. ing.

  FIG. 2 is a plan view of the vicinity of the landing showing an installation example of the building arrival detection means 3 and the landing arrival detection means 4 described above.

  On the lobby floor, building entrances 19, 20, and 21 leading to the elevator entrance / exit are formed. In each entrance 19 to 21, a building that detects the arrival of a user and personal identification information The arrival detection means 3A to 3N are arranged in a distributed manner.

  In addition, landing arrival detection means 4 for detecting that the user has arrived at the landing is installed at the landing gateway 22 through which the user entering from each of the entrances 19 to 21 passes to go to the exit / exit. Yes. In the vicinity of the landing arrival detection means 4, a notification means 5 for notifying the boarding number is arranged. In FIG. 2, the example of installation in case the alerting | reporting means 5 is suspended from the ceiling is shown.

  The landing arrival detection means 4 may be a means for detecting that the user has arrived at the landing and personal identification information as in the building arrival detection means 3A to 3N, or may be configured as a call registration means for performing a call registration operation. It is also possible to detect that the user has arrived at the landing.

  As described above, the landing arrival detection means 4 and the building arrival detection means 3A to 3N can monitor the personal identification information of the user and the movement state of the user. By utilizing these information, the user can be monitored. The operation of the boarding machines 1A to 1N is managed by the group management means GM so as not to cause a long wait.

Here, in the present embodiment, for example, when a 5-story office building is used, as described above, the floor on which each of the boarding machines 1A to 1N is individually serviced is determined. For example, the boarding machine 1A is limited to services for the first floor, the second floor, and the third floor. In addition, the boarding machine 1B is limited to services on the first and fourth floors, and the boarding machine 1N is limited to services on the first and fifth floors. A boarding machine to be boarded according to the use floor is assigned in advance. In an office building, there are cases where different business operators are occupying, or even the same business operator belongs to different organizational units. For this reason, since the floor is determined corresponding to the business operator to which the user belongs and the organizational department to which the user belongs, the boarding number of the user is assigned accordingly. Therefore, personal identification information is detected from the landing arrival detection means 4 and the building arrival detection means 3.

  Next, a basic processing operation in the group management elevator apparatus according to the present embodiment configured in such a system will be described.

  When the arrival of the user is detected by the building arrival detection means 3 arranged at the entrance of the building, the arrival detection unit 8 takes in the personal identification information from the building arrival detection means 3 and the position information of the building arrival detection means 3. The information is input to the landing arrival time calculation unit 11.

  The landing arrival time calculation unit 11 that has received the position information and the personal identification information from the arrival detection unit 8 is a user information management unit 9 that manages the arrival time of the user's landing in the building, and each of the boarding stations 1A to 1A. Based on information from the operation information management unit 10 that manages 1N current and future operation information, if it is determined that congestion is expected, the current congestion status and past usage history in the building The landing arrival time corresponding to the user detected by the building arrival detection means 3 is calculated.

  Next, the user grouping formation unit 12 uses the user's personal information calculated by the landing arrival time calculation unit 11 and the user's landing arrival time and the elevator operation information acquired from the operation information management unit 10. Group. As an example of this grouping, for example, when multiple users gather at the landing at almost the same time zone, when multiple users move to the same destination floor at almost the same time zone, or when multiple users are almost the same There are cases where the vehicle sequentially moves to each of a plurality of stop floors in a time zone.

  Moreover, it can also classify | categorize into a large group and a small group according to these groupings. Needless to say, grouping examples are not limited to these, and grouping can be performed according to other criteria.

  Next, the user information management unit 14 of the group management control means 7 that has received the grouping information from the user grouping formation unit 12 manages the user information of the users in the detected group. Thereafter, the temporary allocation unit 15 temporarily allocates each boarding number to the users of each group and calculates the arrival time of each boarding number.

  Next, the allocation evaluation unit 16 determines the arrival time at the platform of each boarding vehicle when temporarily allocated to each boarding vehicle by the temporary allocation unit 15 based on the destination floor, the door opening / closing time, and the departure suppression time when the door is closed. The allocation will be decided for the number of passengers that can be adjusted to increase the transport capacity and reduce the number of long waiters.

  Then, the operation information determination part 17 determines the operation information of each boarding car, gives command information to each boarding machine control means 2A-2N, and gives command information also to the driving information notification part 13. FIG. The operation information notification unit 13 monitors the arrival of the corresponding user at the landing by the landing arrival detection means 4, and when the landing arrival detection means 4 detects the corresponding user, the user who has received the boarding machine information. It is to provide.

  The above is the basic processing operation. Next, this processing operation will be described in more detail. FIG. 3 is an explanatory view for explaining the grouping process and the boarding car assignment process.

  In FIG. 3, the movement situation with a user's passage of time, its grouping, and the operation | movement forecast route of each boarding machine 1A-1N are shown. In the figure, “◆” indicates the arrival of the user in the building and the elevator boarding, “◇” indicates the arrival of the user at the elevator platform, the solid line “−” indicates the movement state of the user, and the dotted line “-” indicates the movement of the user. Indicates the waiting state of the user.

  First, the user A moves to the landing after being detected in advance at the time A1 by the building arrival detection means 3 arranged in the building, arrives at the landing, and the user arrival A detection means 4 makes the user A's When arrival is detected, boarding machine information of the boarding machine assigned to the user at the time A2 when it arrives at the landing is provided.

  The time when the user A arrives at the landing is the average required time from the building arrival detection means 3 to the landing arrival detection means 4 (which can be obtained from a lot of past user information) and the past requirements of the user A It can be obtained from the time history. For this reason, other users who arrive at the time when user A arrives at the landing can be grouped as the same group.

  A user group of users who arrive at the time before and after the time A1 is set as a group X. Therefore, at this time, the user A is assigned to the boarding car 1A as a member of the group X. The assigned boarding machine 1A passes the time A1 and arrives at the landing at time t1, but the user A gets on the boarding machine 1A as a member of the group X.

  Similarly, user B to user D are also subjected to grouping processing by the user grouping forming unit 12 in accordance with user A. For this reason, other users who arrive at the landing at approximately the same time are also in the same group X, and the same board number information is provided at the time of arrival at the landing, and board the boarding machine 1A that has arrived at the landing at time t1. It will be. In this way, the users A to D are grouped in accordance with the arrival time at the landing and board the same boarding machine 1A as the group X.

  Here, in the boarding car 1A, the operation route is adjusted so that the users of the group X gather and arrive at the landing at the time t1 when all the members of the group X will be gathered. This can be executed by the allocation evaluation unit 16.

  A plurality of users E to I are grouped as a group Y in accordance with the arrival time at the landing for the boarding machine 1N that arrives at the landing at the subsequent time t2, and board the same boarding machine 1N. . These time zones t1 and t2 are not congested at this time, and are in a normal operation state, and a plurality of users are grouped and boarded in groups according to the arrival time at the landing. Can be kept high. However, the destination floors as the predetermined conditions are determined for the boarding stations 1A and 1N corresponding to the next congestion time. This will be described later.

  In this way, when users are grouped according to the arrival time at the landing, rather than being distributed individually as in the past, the largest user expected after that Even when the group Z visits, it is possible to efficiently transport.

  That is, in accordance with the expected congestion time when the user group Z having the largest number of users arrives at the landing and is crowded, the boarding machine 1B is dispatched to the boarding at the time t3, and then the boarding machine 1A is brought to the boarding at the time t4. It is possible to make an operation plan while adjusting the arrival time of each boarding car so that it can be dispatched.

  The largest user group Z at this time is a group of users J, L to N, S who will get on boarding machine 1B at time t3, and users who will get on boarding machine 1A at time t4. It is divided into K and O to R groups.

  It is to be noted that the crowded congestion prediction time can be obtained from the average required time from the building arrival detection means 3 to the landing arrival detection means 4 or the past required time history of the user. For this reason, the estimated congestion time when many users arrive at the landing can be easily estimated.

  Next, the adjustment method of the arrival time to the boarding place of each boarding machine 1A-1N mentioned above with respect to group Z is demonstrated. Here, since the number of users and the arrival time at the landing are known by the building arrival detection means 3 as described above, the time when the future congestion occurs can be estimated.

  Therefore, as shown in FIG. 3, the time adjustment shown in the operation route diagram is performed so that the boarding machine 1B that departs from the landing before the current time arrives at the landing at time t3 in preparation for future congestion. Time adjustment is planned in area 22. This time adjustment can be adjusted by adjusting the combination of destination floors decided to stop, the door opening and closing time, and the departure time, which is a predetermined condition. Can be realized.

  On the other hand, among the boarding stations 1A and 1N that will depart from the landing a little later than the current time, the allocation of the boarding station 1A is such that the user group Z can return to the boarding at time t4 that is close to time t3 when the user group Z arrives at the boarding. Will be done. The dispatch of the boarding machine 1A is determined from the fact that the boarding machine 1A serves the floors close to the generation platform (hereinafter referred to as the neighboring floors) such as the first floor, the second floor, and the third floor as described above. ing. In other words, since a service is provided for a nearby floor close to the generation platform, it is possible to return to the platform in a short time toward time t4 even if the departure is made in advance. In order to execute this, grouping indicated by groups X and Y is important.

  Next, grouping to boarding machines 1A and 1N that will depart the landing a little later than the current time will be further described. FIG. 4 is an operation route diagram of the car numbers 1A to 1N partially enlarged from FIG.

  FIG. 4 shows an operation route diagram of the boarding machines 1A to 1N described in FIG. 3. In preparation for future congestion, the boarding machine 1B is dispatched to the landing at time t3, and the boarding machine 1A at time t4. We are trying to dispatch to the platform. Note that the vicinity of times t3 and t4 is defined as a predicted congestion time.

  Prior to the current time at the time indicated on the horizontal axis, the user who forms the group Z has been detected by the building arrival detection means 3, so that the occurrence of the destination floor call 23 can be predicted, and The destination floor for each user is displayed on the axis.

  Aside from these users who are calling the destination floor, the boarding machine 1A that gets on at time t1 has a floor far from the landing floor of the call generation floor as shown in the operation route line 24 (hereinafter referred to as a far floor). The group X for the destination floor call on the adjacent floor is assigned, so that it can arrive at the landing at time t4 near time t3. By such assignment, the boarding machine 1A can immediately return to the landing on the lobby floor in accordance with a predicted future congestion time.

  Therefore, returning to FIG. 3, the group X is shown in a simplified manner, but the users of the group X are users who move on the adjacent floor. This grouping can be easily classified because the use floor of the user is registered in advance.

  On the other hand, as shown in the operation route line 25, the group Y targeting the call on the far floor is assigned to the boarding car 1N to be boarded at time t2, in order to support the driving of the car 1A. In other words, in preparation for the future congestion at time t3, the vehicle number 1A is allocated at time t1 so as to return to the landing at time t4, and at time t2, the vehicle number 1B is allocated corresponding to the user on the far floor. By doing so, grouped assignments are made so as to predict the congestion of future platforms and provide sufficient transportation capacity.

  Further, as described with reference to FIG. 4, the boarding machine 1 </ b> B has time in the time adjustment area 22 shown in the operation route diagram so as to arrive at the landing at time t <b> 3 in preparation for future congestion as shown in the operation route line 26. We are trying to make adjustments. In this way, the advance car number in consideration of the destination floor in preparation for the future congestion due to the time adjustment in the time adjustment area 22 of the previous time-departed car number shown in FIG. 3 and the grouping in the future. In this way, the necessary transportation capacity can be obtained at the time of congestion in the future.

  In this way, the adjacent floor users are transported in groups by the adjacent floor assigned machine 1A, the far floor users are transported in groups by the far floor assigned car 1N, and the preceding machine 1B and the adjacent floor are transported in groups. Since the allocated number machine 1A divides a large group of users at the time of congestion and transports them in groups, it is possible to efficiently reduce congestion at the landing.

  Next, a specific control flow of these controls will be described. FIG. 5 is a flowchart showing grouping processing on the user management means 6 side.

  In FIG. 5, first, in step S1, the user grouping forming unit 12 determines whether the number of people who arrive at the landing within a predetermined time is greater than or equal to a preset arrival number threshold or less than the arrival number threshold, and enters the landing. It is determined whether the number of arrivals exceeds the arrival number threshold. If it is determined in step S1 that the arrival number threshold is not exceeded, the process returns to step S1. If it is determined that the number of people who arrive within the predetermined time exceeds the arrival number threshold, the process proceeds to step S2.

  In step S2, the user grouping forming unit 12 groups the users whose arrival intervals at the landing are within a preset first interval threshold based on the current time from the distribution of the arrival times of the users. sign up. When this is completed, the process proceeds to step S3.

  In step S3, the user grouping forming unit 12 determines whether the number of groups exceeds a preset group number threshold. As a result, if the group number threshold is exceeded, a larger group is set in step S4. On the other hand, if the group number threshold is not exceeded, a small group is set and registered in step S5. These pieces of information are sent to the user information management unit 14 of the group management control means 7.

  FIG. 6 is a flowchart showing a boarding machine assignment process for dispatching a car at a crowded time by adjusting a small group without dividing a large number group on the group management control means 7 side. Here, description will be made assuming that the grouping information received by the user information management unit 14 includes a large number group and a small number group.

  The flowchart shown in FIG. 6 is processing related to a boarding machine that services a small group when it is detected that a large group exists.

  In step S6 of FIG. 6, when the temporary allocation unit 15 detects that there is a large group in the grouping information received by the user information management unit 14, the temporary allocation unit 15 sets the arrival time of the large group in step S7. A target arrival time t3 is set so that the car arrives. This target arrival time t3 is a congestion prediction time at which congestion is expected. At this time, the boarding car (for example, boarding machine 1B) that has departed in advance is assigned to arrive at the target arrival time t3. When this is completed, the process proceeds to step S8.

  In step S <b> 8, the temporary allocation unit 15 sets a machine that serves a small group. That is, a boarding car that returns to the landing at time t4 close to the target arrival time t3 described above is temporarily allocated. In this case, each of the small group passengers can return to a nearby floor where they can quickly return to the landing (for example, the passenger car 1A), or a far floor (hereinafter referred to as a floor for supporting this nearby floor). , Provisionally assigned a boarding car (for example, boarding car 1N) that services a far floor. When this is completed, the process proceeds to step S9.

  In step S9, the allocation evaluation unit 16 determines the allocation to the boarding car (for example, boarding car 1A) that returns to the landing at time t4 closest to the target arrival time t3. As a result, an appropriate boarding number can be dispatched near the estimated congestion time when the future congestion situation is predicted, so that it is possible to suppress the long wait of the user and improve the transportation capacity.

  FIG. 7 is a flowchart showing a car number assignment process for allocating a car at a congested time by adjusting a small number of groups by dividing the large number group on the group management control means 7 side into a plurality of times and also dividing the congested time. The grouping information received by the user information management unit 14 will be described as having a large group and a small group. Here, the difference from FIG. 5 is that steps S10 and S11 are replaced instead of step S7. Therefore, description of the same control steps is omitted.

  In step S6, if the provisional allocation unit 15 detects that there are a large number of groups in the grouping information received by the user information management unit 14, in step S10, the temporary allocation unit 15 identifies a large number of groups for each destination floor. Divide into destination floor groups. For example, it can be classified as a group heading to the first to third floors and a group heading to the fifth floor. When the division of the large group is completed, the process proceeds to step S11.

  In step S11, a plurality of target arrival times are set so that the car arrives at the arrival completion time for each destination floor group divided into a large number of groups. This target arrival time is a congestion prediction time at which congestion is expected. And for example, the group which goes to the 1st floor-the 3rd floor can be assigned to boarding machine 1B, and the group which goes to the 5th floor can be assigned to boarding machine 1A.

  Thereafter, the same processing as in FIG. 6 is performed. According to the process shown in FIG. 7, the number of users in the large group can be divided. Therefore, in the process shown in FIG. 6, when the car that can arrive near the congestion time cannot be allocated, or when the number of boarding cars is large, The degree of freedom to do can be expanded.

  Furthermore, by using the processes of FIG. 6 and FIG. 7 together, it becomes possible to select a car that can arrive near the congestion time.

  Furthermore, by using the processes of FIG. 6 and FIG. 7 together, it becomes possible to select a car that can arrive near the congestion time for the next large group. That is, even when congestion continues, the effect can be continuously exhibited.

  Next, more specific boarding machine assignment processing on the group management control means 7 side will be described in detail based on the flowchart shown in FIG. It should be noted that the classification of the large number group and the small number group has already been executed in FIG.

  First, in step S12, prior to the assignment of the boarding number of the small group, the temporary allocation unit 15 temporarily allocates a large group of a predetermined number or more to the predetermined number of cars that arrive at the target arrival time. By assigning the large number group first, the flexibility of time adjustment for returning the assigned boarding machine of the small group starting first to the landing again increases. When this temporary allocation is completed, the process proceeds to step S13.

  In step S13, is there a boarding machine that departs from the floor (generally the lobby floor) where the small group occurred, from the first person's arrival in the small group to the last person's arrival? Determine. If there is no departure car number, the process proceeds to step S19, and if there is a departure car number, the process proceeds to step S14. The processing after step S19 will be described later.

  In step S14, the small group is divided into a plurality of groups for each destination floor and evaluated. This evaluation is performed by the allocation evaluation unit 16 as described above. In other words, as a result of adjusting the arrival time of each boarding machine when temporarily assigned to each boarding car by the temporary allocation unit 15 by the landing call on the other floor, the destination floor, door opening and closing time, departure restraint, the transport capacity is most enhanced, In addition, the assignment is decided to the boarding machine that can reduce the number of long waiters.

  In addition, this allocation evaluation is based on the number of vehicles that serve the nearby floor where each small group passenger can quickly return to the landing, and the number of vehicles serving the far floor to support the number of vehicles that serve this nearby floor. Temporarily assigned. This has already been explained. When the assignment evaluation of the small group is completed, the process proceeds to step S15.

  In step S15, the temporary allocation unit 15 departs from the floor (generally the lobby floor) in which the large number group occurred from the first arrival of the first large number group until the last one arrives. Determine if there is a boarding machine. If there is no departure car number, the process proceeds to step S19, and if there is a departure car number, the process proceeds to step S16.

  In step S16, the large number group is divided into a plurality of destination floors and evaluated for allocation. The reason for the division is to evaluate whether the allocation is more optimal by dividing the large number group for the arrival time of each boarding machine that was provisionally determined by the temporary allocation at the time of dividing the small group, or the large number of people This is because all the users of the group cannot be put on one boarding car, or in order to quickly eliminate the congestion of the boarding place by a large number of groups, the transportation volume is increased by dividing.

  In this allocation evaluation, a large group is divided into a plurality of destination floor groups by destination floor. For example, it can be classified as a group heading to the first to third floors and a group heading to the fifth floor. When the division of the large group is completed, the target arrival time is set so that the car arrives at the arrival time of the large number group for each divided destination floor group. When the target arrival time is set, a boarding number to be boarded is assigned. This can be done in the manner shown in FIG. When step S16 is completed, the process proceeds to step S17.

  In step S17, it is determined whether there is a boarding machine that departs from the generation floor of the small group from the first arrival in the small group to the last one. If there is no departure car number, the process proceeds to step S19, and if there is a departure car number, the process proceeds to step S18.

  In step S18, the door opening / closing time when the boarding car that departs before the starting car is not boarding is adjusted. It is also possible to change the destination floor. This can also be carried out by the method shown in FIG. As a result, the operation route can be adjusted to arrive at the landing at the target arrival time. When step S18 is completed, the process proceeds to step S19.

  In step S19, the allocation evaluation unit 15 determines an allocation to a boarding machine having the smallest waiting number of people on the departure floor platform. Many users will gather at the platform on the departure floor, but the users at the platform are placed on as many corresponding car numbers as possible to eliminate congestion at the platform.

  For example, the adjacent floor users are transported as a group by the assigned floor 1A, the far floor users are transported by the far floor 1N, and the preceding floor 1B and the nearby floor are assigned. With 1A, a large group of users at the time of congestion is divided and transported in groups, so it is possible to efficiently reduce congestion at the landing. Of course, it is needless to say that long waiting time and the number of long waiting users can be considered as one of the evaluation indexes, and long waiting time can be suppressed.

  FIG. 11 is a graph showing the passage of time at work in a building and the transition line of the waiting number at the lobby floor platform. As can be seen from FIG. 11, the number of users tends to increase as time passes, as indicated by the transition line 27. The building arrival detection means 3 and the user management means 6 can predict the occurrence of congestion on the lobby floor at the time of work.

  Then, as shown in FIG. 12, for example, by assigning each boarding car using a car 30 with a capacity of 20 by the above-described grouping process and assignment process, the number of people remaining at the landing on the lobby floor is: It changes like a transition line 28. In addition, as can be seen from the operation route line 29 of each boarding car at this time, the service interval of each boarding machine where the maximum waiting number is minimized so as not to exceed the maximum waiting number threshold 31 of the boarding place. Can do.

  In addition, if the control which suppresses long waiting is performed by monitoring the maximum waiting time for every destination floor, long waiting can be further suppressed. For example, as shown in the figure, the maximum waiting time for users going to the fifth floor does not become extremely long.

  Next, in step S20, the operation information determination unit 17 determines whether the target user has been detected by the landing arrival detection means 4 and has arrived at the landing, and if it has arrived at the landing, proceeds to step S21 and is notified by the notification means 5. Inform the user of the boarding machine to be boarded.

  Next, another assignment processing method different from the boarding car assignment processing method on the group management control means 7 side shown in FIG. 8 will be described with reference to FIG. This boarding car allocation processing method is different in that step S19 is changed to step S22. Therefore, description of the same control steps is omitted.

  In step S19 of FIG. 8, the assignment is decided to the boarding machine having the smallest waiting number at the landing. On the other hand, in step S22, the assignment is decided to the boarding machine that has the smallest number of people who have been waiting for a predetermined time or more at the landing. In this case, since the arrival time is obtained for each group, it is only necessary to evaluate the allocation so that a boarding machine assigned within a predetermined time such as a long waiting time or an irritated time arrives at the landing. . According to this, the number of long waiting occurrences over a predetermined time can be minimized, and as a result, the waiting time can be averaged to further improve the operation efficiency as a whole.

  Next, another assignment processing method different from the boarding car assignment processing method on the group management control means 7 side shown in FIG. 8 will be described with reference to FIG. This boarding car allocation processing method is different in that step S19 is changed to step S23. Therefore, description of the same control steps is omitted.

  In step S19 of FIG. 8, the assignment is decided to the boarding machine having the smallest waiting number at the landing. On the other hand, in step S23, it is different in that assignment is determined to a boarding machine whose arrival interval to the lobby floor is averaged among the temporarily changed boarding machines. In this case, it is only necessary to manage the one lap time of each boarding car and adjust the time so that the one lap time is averaged. According to this, since the arrival interval to the lobby floor is averaged, dango driving is suppressed, and overall operation efficiency can be further improved. In addition, a stable effect can be exhibited even when there is a large error from the estimated arrival time or the estimated number of people.

  Thus, according to the present embodiment, since the waiting time is averaged in the lobby floor serving as the reference floor, the waiting time in the reference floor where congestion is expected is averaged, and the overall operation efficiency is further improved. Can be improved.

  Further, since the embodiment shown in FIGS. 8 to 10 basically performs the same processing, the situation at the time of congestion is learned, and the maximum waiting number of people at the landing is minimized in step S19 in FIG. The process of determining the assignment to the boarding machine, the process of determining the assignment to the boarding machine having the minimum number of long-waiting occurrences for a predetermined time or more in step S22 in FIG. 9, and the lobby among the boarding machines temporarily changed in step S23 in FIG. It is also possible to switch and execute the process of determining the assignment to the car number where the arrival interval to the floor is averaged.

  As described above, according to the present invention, a grouping of users is performed by predicting future congestion using the arrival times of a plurality of users and the current operation information of each boarding machine, and this grouped information Based on the above, the temporary allocation of the passenger numbers corresponding to each group is performed, and the predicted arrival time when the departure vehicle arrives at the platform again before the predicted congestion time is predicted to be crowded. Adjustment is made under predetermined conditions so as to arrive in the vicinity, and this adjusted boarding machine is determined as a boarding machine that arrives in the vicinity of the predicted congestion time when congestion is expected.

  According to this, the car can be dispatched smoothly to the platform near the congestion time when the congestion situation is predicted. Therefore, when the future congestion is predicted, it is possible to improve the transportation capacity of the user by suppressing the long wait for the user at the landing.
