  Hereinafter, embodiments will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing a configuration of an elevator group management system according to the first embodiment. In the example of FIG. 1, a configuration in which four elevators are group-managed is shown, but the configuration is not limited to this configuration. In addition, when there are a plurality of elevators, the term “unit” is used.

  The machine control units 11a, 11b, 11c, and 11d are provided corresponding to the cars 12a, 12b, 12c, and 12d of each car, and include drive control and door opening / closing control (not shown). Control the unit alone. The cars 12a, 12b, 12c, 12d move up and down in the hoistway by driving a hoisting machine (not shown).

  On the other hand, a landing destination floor registration device 13 is installed at the landing on each floor. The landing destination floor registration device 13 is a device for a user to register a destination floor at the landing on each floor, an operation unit 14 for registering the destination floor, and a display unit 15 for displaying the reference number. Have As a destination floor registration method, a method using a numeric keypad is generally used. However, a method using a card reader or a wireless IC may be used as long as registration is possible at the landing.

  In addition, a display device 16 corresponding to each unit is installed at the landing on each floor. The display device 16 is composed of, for example, a liquid crystal display, and displays information related to the operation of each unit including a serial number.

  When the destination floor registration is performed by the landing destination floor registration device 13, the hall call information including the two information of the destination floor and the registered floor (the floor on which the user performs the registration operation) as one set is group management controlled. It is output to the device 20.

  The group management control device 20 is a device that performs group management control on the operation of each car (cars 12a, 12b, 12c, 12d). In the present embodiment, the group management control device 20 includes a registration control unit 21, an ID issuing unit 22, an allocation control unit 23, a boarding determination unit 24, and a display control unit 25. These are processing units executed by software on a microprocessor, and information can be exchanged between the respective units as shown in FIG.

  Here, for convenience, the registration control unit 21, ID issuing unit 22, assignment control unit 23, boarding determination unit 24, and display control unit 25 are all described in the group management control device 20, but are not necessarily the same device. It is not necessary to arrange them, and they may be arranged in separate devices.

  The registration control unit 21 has an ID management table 21a as shown in FIG. 2, and stores the hall call information and the assigned number machine in the ID management table 21a for each reference number (ID) issued by the ID issuing unit 22. . As described above, the hall call information includes two pieces of information: a destination floor and a registered floor. Also, the assigned number means a number assigned to the hall call information by the assignment control unit 23.

  In the example of FIG. 2, registration floor: 1F, destination floor: 5F, and assigned machine: B are registered in the ID management table 21a for ID: 1. This means that the user operates the 1F landing destination floor registration device 13 to register 5F as the destination floor, and at that time, ID1 is issued as the reference number and Unit B is assigned.

  The ID issuing unit 22 issues a reference number (ID) to the user in accordance with the operation of the landing destination floor registration device 13. This reference number is unique to each user, and is issued in the order in which the destination floors are registered by the landing destination floor registration device 13.

  The assignment control unit 23 selects a car to which the hall call information is assigned based on the operation information of each car, and makes the car respond to the registration floor as the car assigned. In addition, as a method of assigning elevators to hall calls, generally known methods are used. In general, for example, a method is used in which an evaluation value is obtained based on information such as the position and direction of the car of each car, and the car having the highest evaluation value is assigned as the optimum car.

  The boarding determination unit 24 refers to the ID management table 21a to calculate the number of passengers and the number of waiting people when the assigned car arrives at the registration floor, and whether or not the user can get on the assigned car based on the calculation result. Judging.

  The display control unit 25 displays the reference number on the landing destination floor registration device 13 at the time of registration of the destination floor, and when the boarding judgment unit 24 determines that the user can get on the assigned number machine, the assigned number machine The reference number is displayed on the display device 16 corresponding to.

  FIG. 3 is a diagram showing an installation example of the landing destination floor registration device 13 and the display device 16 provided at the landings on each floor. In the figure, 17 represents a landing for each unit, and 18a to 18d represent landing doors for each unit.

  In this example, the landing destination floor registration device 13a is between the landing door 18a of Unit A and the landing door 18b of Unit B, and the landing destination floor registration device is between the landing door 18c of Unit C and the landing door 18d of Unit D. 13b is installed. In addition, display devices 16a to 16d are installed on landing doors 18a to 18d of each unit.

  The landing destination floor registration devices 13a and 13b are common to each unit, and the user who comes to the landing 17 operates either of them to register the destination floor. The display device 16a is for Unit A, the display device 16b is for Unit B, the display device 16c is for Unit C, and the display device 16d is for Unit D. The display device 16a displays the reference number of the user who gets on the No. A machine. Similarly, the display device 16b displays the reference number of the user who gets on Unit B, the display device 16c displays the reference number of the user who gets on Unit C, and the display device 16d displays the reference number of the user who gets on Unit D. To do.

  FIG. 4 is a diagram showing an external configuration of the landing destination floor registration device 13.

  The landing destination floor registration device 13 is provided with an operation unit 14 and a display unit 15. In the example of FIG. 4, the operation unit 14 includes a plurality of button keys, and the user registers a destination floor by depressing these button keys. The display unit 15 is arranged at the upper part of the operation unit 14 and displays the reference number issued to the user who registered the destination floor for a certain period of time. In the example of FIG. 4, the reference number “10” is displayed.

  FIG. 5 is a diagram showing an example of reference numbers displayed on the display device 16.

  The display device 16 displays the reference number of the user who gets on the car corresponding to the display device 16. In the example of FIG. 5, “3”, “10”, “11”, and “15” are displayed as the reference numbers. That is, a user having these reference numbers can get on the car corresponding to the display device 16. The reference number displayed on the display device 16 is cleared after the arrival of the machine.

  FIG. 6 is a diagram showing an example of the serial number displayed on the display device 16 of another machine.

  When the user cannot get on the car assigned to the hall call information, the assignment is changed to another car. In the example of FIG. 6, the reference number “10” is displayed on the display device 16 of another unit.

  Next, the operation of the first embodiment will be described.

  FIG. 7 is a flowchart showing the processing operation of the elevator group management system in the first embodiment. Note that the processing shown in this flowchart is executed by the group management control device 20 which is a computer reading a predetermined program.

  Now, it is assumed that the user a has registered the destination floor by operating the operation unit 14 of the landing destination floor registration device 13 on an arbitrary floor.

  When the destination floor is registered by the landing destination floor registration device 13, the hall call information including the destination floor and the registered floor is given to the registration control unit 21 of the group management control device 20 (step A11). At that time, a reference number (ID) for the user a is issued by the ID issuing unit 22 (step A12), and the destination floor and the registered floor of the hall call information are stored in the ID management table 21a in association with the reference number. (Step A13).

  At this time, the display control unit 25 displays the reference number issued by the ID issuing unit 22 on the display unit 15 of the landing destination floor registration device 13 registered by the user a (step A14). In the example of FIG. 4, the reference number “10” is issued and is displayed on the display unit 15 of the landing destination floor registration device 13. By displaying the reference number on the landing destination floor registration device 13 at the time of registration, the user a can confirm the reference number issued to himself / herself.

  On the other hand, the allocation control unit 23 refers to the ID management table 21a and executes an allocation process for a newly issued serial number (step A15). Specifically, the operation information (car position, driving direction, door open / closed state, etc.) of each car is acquired from the car controllers 11a, 11b, 11c, and 11d. Then, these pieces of information are substituted into a predetermined evaluation function formula to obtain the evaluation value of each unit, and the unit having the highest evaluation value is selected and assigned hall call information.

  A car to which hall call information is assigned is called an assigned car. When an assigned car is determined, an assignment command is output to the car controller corresponding to the assigned car in the car controllers 11a, 11b, 11c, and 11d, and the assigned car (car) responds to the registration floor. (Step A16).

  Here, the registration control unit 21 adds the assigned number to the ID management table 21a and updates the table contents (step A17). The display control unit 25 refers to the updated ID management table 21a and confirms the number of passengers at the time of arrival of the assigned car (the number of persons remaining in the car) and the number of waiting persons (boarding before the user a). (Step A18), and it is determined from the calculation result whether the user a can get on (step A19).

  In this case, if the number of passengers on arrival is P1, the waiting number is P2, and the rated number of people who can get in the car of the unit is P3, the number of passengers satisfying the following conditions (that is, the number of passengers P1 plus waiting number P2) Is less than the rated number of people P3), it is determined that the user a can get on.

P1 + P2 <P3 (1)
If the user a can get on (Yes in step A19), the display control unit 25 displays the reference number of the user a on the display device 16 corresponding to the assigned number machine, so that the user a can board the user a. (Step A20). For example, if the reference number of the user a is “10”, “10” is displayed on the display device 16 as shown in FIG.

  On the other hand, before the assigned machine arrives, a large number of users may get on other floors and arrive near the full capacity. In addition, there are cases where there are a large number of users who have registered before user a, so that they cannot get on. In such a case, since the condition of the above equation (1) is not satisfied, it is determined that boarding is not possible.

  When it is determined that boarding is not possible (No in step A19), the reference number of the user a is not displayed. In this case, the display of the reference number is put on hold until the process returns to step A15 and the assignment is changed to another unit. Then, when the user a can get on the assigned car, the information is displayed on the display device 16 corresponding to the car.

  This state is shown in FIG. 6, and the reference number “10” is displayed on the display device 16 of another unit. Even if the boarding is not possible due to a failure of the number machine, the assignment number is changed to another number, and the reference number is displayed when the user a can board the numbered car.

  As described above, according to the first embodiment, a reference number is issued when a user registers a destination floor, and the reference number is displayed on the display device of the relevant unit when a boarding machine arrives. The Therefore, if the user is waiting in front of the corresponding unit at the timing when the reference number is displayed, the user can get on that unit and go to the destination floor.

  A system that displays a reference number at a bank or hospital counter is known. However, this type of system usually only displays the serial number in sequence, and the serial number is displayed at an appropriate timing in an environment where the operation information of each unit changes dynamically as in the elevator group management system. It is fundamentally different from what is displayed.

(Second Embodiment)
Next, a second embodiment will be described.

  In the second embodiment, the display of the reference number is controlled based on the response time of the assigned number machine.

  FIG. 8 is a diagram showing a configuration of an elevator group management system according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the description shall be abbreviate | omitted.

  In the second embodiment, the group management control device 20 includes a response time calculation unit 26. The response time calculation unit 26 calculates the response time until the car to which the hall call information is assigned by the assignment control unit 23 arrives at the registration floor.

  FIG. 9 is a flowchart showing the processing operation of the elevator group management system in the second embodiment. Note that the processing shown in this flowchart is executed by the group management control device 20 which is a computer reading a predetermined program. Further, the processing from step B11 to B16 is the same as the processing from step A11 to A16 in FIG. 7 in the first embodiment.

  That is, now, if the user a registers the destination floor by operating the operation unit 14 of the landing destination floor registration device 13 of an arbitrary floor, the hall call information including the destination floor and the registered floor is group management control. This is given to the registration control unit 21 of the apparatus 20 (step B11). At that time, a reference number (ID) for the user a is issued by the ID issuing unit 22 (step B12), and the destination floor and the registered floor of the hall call information are stored in the ID management table 21a in association with the reference number. (Step B13).

  At this time, in the second embodiment, the time when the user a registers the destination floor is stored in the ID management table 21a in association with the reference number. In addition, the display control unit 25 displays the reference number issued by the ID issuing unit 22 on the display unit 15 of the landing destination floor registration device 13 registered by the user a (step B14).

  On the other hand, the allocation control unit 23 refers to the ID management table 21a and executes an allocation process for a newly issued serial number (step B15). Specifically, the operation information (car position, driving direction, door open / closed state, etc.) of each car is acquired from the car controllers 11a, 11b, 11c, and 11d. Then, these pieces of information are substituted into a predetermined evaluation function formula to obtain the evaluation value of each unit, and the unit having the highest evaluation value is selected and assigned hall call information.

  Here, in the second embodiment, the response time until the assigned machine arrives at the registered floor is calculated by the response time calculation unit 26 (step B17). This response time is obtained based on hall call information (registration floor, destination floor) registered in the ID management table 21a, current position, driving direction, door open / close state, and the like.

  If the response time of the assigned car is equal to or longer than a certain time (for example, 2 minutes) (Yes in Step B18), the assignment control unit 23 temporarily holds the hall call information of the user a (Step B18), and then holds it. The allocation process for the hall call information in the center is performed again (step B15). Meanwhile, the display of the reference number on the display device 16 is in a suspended state.

  On the other hand, if the response time of the assigned number is within a certain time, the assignment control unit 23 determines the assigned number at that time and corresponds to the assigned number in the number control unit 11a, 11b, 11c, 11d. An allocation command is output to the machine control unit to respond to the registration floor (step B19). At this time, the assigned machine number is added to the ID management table 21a in association with the reference number (step B20).

  The subsequent steps are the same as in the first embodiment, and the number of passengers (the number of people remaining in the car) upon arrival of the assigned car and the number of people waiting (the number of persons who have boarded before user a) are determined by the boarding determination unit 24. ) Is calculated (step B21). Then, it is determined from the calculation result whether or not the user a can get on the assigned car (step B22).

  If the user a can get on (Yes in Step B22), the display control unit 25 displays the reference number of the user a and the waiting time on the display device 16 corresponding to the assigned number machine ( Step B23).

  In this case, if it is not suspended in step B18, the response time obtained in step B16 is displayed as an approximate waiting time. Further, if the suspension is made in step B18, a time obtained by adding the suspension time to the response time obtained in step B16 is displayed as an approximate waiting time. Furthermore, if it is determined in step B22 that boarding is not possible and the assignment has been changed, the time is also taken into account.

  FIG. 10 shows a display example of the waiting time. In this example, when the reference numbers “3”, “10”, “11”, and “15” are displayed, “60 seconds” is displayed as the waiting time to indicate the state. Since the waiting time can be displayed, the arrival time of the unit can be determined, so that the user can calmly wait.

  Thus, according to the second embodiment, the reference number is displayed when the assigned machine can respond within a predetermined time. Therefore, it is possible to prevent the user from feeling uncomfortable without arriving after the reference number is displayed. Furthermore, by displaying the waiting time together with the reference number, the user can calmly wait.

  According to at least one embodiment described above, an elevator group management system that can guide and ride a user in front of a car that can be boarded by displaying the user's reference number at an appropriate timing. Can be provided.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
