Description

  Embodiments described herein relate generally to an elevator group management system including a landing destination floor registration device capable of registering a destination floor at a landing.

  Normally, when using an elevator, the user operates the UP direction (up direction) or DN direction (down direction) buttons installed on the landing area to register the hall call and responds to the registration floor. After getting on, perform operations such as registering a car call on the destination floor.

  On the other hand, in an elevator equipped with a device that can register a destination floor at a landing (this is called a landing destination floor registration device), a user can register a destination floor in advance at the landing. No registration operation is required.

  Here, in a group management system having a plurality of elevators, when a user registers a destination floor at a landing, an optimal number is assigned from among the numbers. In this case, since the destination destination floor registration device knows the destination floor of the user in advance, the assignment control is performed so that the same destination floor or a user who is close to the destination floor gets on the same machine. When the assigned number is determined, the number of the number is displayed on the landing destination floor registration device. The user can wait in front of the landing of the displayed unit, get on after arrival and move to the destination floor.

  In the landing destination floor registration method, the same destination floor or a user who is close to the destination floor is assigned to the same unit, thereby reducing the number of stops and increasing the operation efficiency. At this time, the information to be referred to is only the destination floor of the user, and the user attributes (VIP, general, etc.) are not considered. For this reason, for example, a special user and a general user may ride on the same unit, and the general user can go to the special floor (VIP floor) at that time, which is a security problem. Occurs. Although there is a method in which only special users are always preferentially assigned to the same unit, a dedicated unit that operates only the special users is created, and operation efficiency is significantly reduced.

  The problem to be solved by the present invention is to provide a group management system for elevators that can be operated with the security of the users being eliminated by eliminating the need to join users with different attributes without using a dedicated machine. It is.

  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, it is also referred to as “unit”.

  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 assigned number machine. Have In this embodiment, when a destination floor is registered by the hall destination floor registration device 13, an ID number for identifying a user together with the destination floor is registered by operating the operation unit 14.

  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 a liquid crystal display, for example, and displays the stop floor of each unit.

  When the destination floor and ID number are registered by the landing destination floor registration device 13, the hall call information that combines the two information of the destination floor and the registered floor (the floor on which the user performed the registration operation) into one set is obtained. The ID number is assigned and output to the group management control 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 mode setting unit 21, a user attribute determination unit 22, a registration control unit 23, an allocation control unit 24, an allocation change unit 25, and a display control unit 26. . 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 mode setting unit 21, the user attribute determination unit 22, the registration control unit 23, the allocation control unit 24, the allocation change unit 25, and the display control unit 26 are all arranged and described in the group management control device 20. However, it is not necessarily arranged in the same device, and may be arranged in different devices.

  The mode setting unit 21 sets a security mode that determines an assigned machine in consideration of user attributes. The user attribute determination unit 22 has a database 22a for managing attributes in association with user ID numbers. When the security mode is set, the user attribute determination unit 22 refers to the database 22a and gets on the assigned number machine. Determine the attributes of. The “user attribute” here is defined by a floor that can be registered.

User attributes will be described with reference to FIG.
Now, a building having 1 to 15 floors is assumed. It is assumed that 1 to 5F are office floors, 6 to 10F are general floors, and 11 to 15F are special floors.

  Here, the user attributes are classified into Pa = special user (VIP), Pb = general user, Pc = other users. Normally, each floor can be freely registered as a destination floor regardless of the attributes of the user. On the other hand, when the security mode is set, the floors that can be registered are limited by the user attributes.

  That is, the special user Pa can register all floors 1 to 15F as destination floors. On the other hand, the general user Pb can register 1 to 10F as the destination floor excluding the special floors of 11 to 15F. In addition, other users Pc can register only 1 to 5F as destination floors, excluding special floors of 11 to 15F and general floors of 6 to 10F.

  As shown in FIG. 3, such user attributes are managed in the database 22a in association with ID numbers. In the example of FIG. 3, for example, the user with ID number “001” is registered as a special user Pa, and it is shown that all floors 1 to 15F can be registered as destination floors in the security mode. . Further, it is indicated that the user with the ID number “002” is registered as a general user Pb, and that 1 to 10F can be registered as a destination floor in the security mode. The user with ID number “003” is registered as the other user Pc, and it is indicated that 1 to 5F can be registered as the destination floor in the security mode.

  Moreover, the registration control part 23 has the management table 23a as shown in FIG. 4, and memorize | stores hall call information and an assigned number machine in a management table 23a with ID number. 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 24. The destination floor is referred to as a “destination floor” in terms of elevator operation management.

  In the example of FIG. 4, for the ID: 001, the registration floor: 1F, the destination floor: 5F, and the assigned number machine: B number are registered in the management table 23a. This means that the user with the ID number “001” operates the 1F landing destination floor registration device 13 to register 5F as the destination floor, and at that time, Unit B is assigned.

  The assignment control unit 24 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.

  When the user attribute determination unit 22 confirms the boarding of a user having a different attribute, the allocation changing unit 25 changes the number of the car on which the user gets to another car.

  The display control unit 26 sets the assigned number determined by the assignment control unit 24 or the number changed by the assignment change unit 25 as a number that can be used by the user on the display unit 15 of the landing destination floor registration device 13 for a certain period of time. indicate.

  FIG. 5 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 stop floor of Unit A. Similarly, the display device 16b displays the stop floor of Unit B, the display device 16c displays the stop floor of Unit C, and the display device 16d displays the stop floor of Unit D.

  FIG. 6 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. 6, the operation unit 14 includes a plurality of button keys, and the user registers the destination floor and the ID number by pressing these button keys. The display part 15 is arrange | positioned at the upper part of the operation part 14, and displays the number of the number machine (assignment number machine) which the user who registered the destination floor can board. In the example of FIG. 6, Unit A is displayed.

  FIG. 7 is a diagram showing an example of the stop floor displayed on the display device 16a of the A machine.

  On the display device 16a, the stop floor of Unit A corresponding to the display device 16a is displayed. In the example of FIG. 7, “10F”, “11F”, and “15F” are displayed as the stop floors. This stop floor corresponds to the destination floor of the user assigned to Unit A.

  Here, when the security mode is set, the destination floor of the user with different attributes is reassigned to another machine. For example, if the attribute of the user who registered “10F” is the general user Pb, the user who registered “11F” and the attribute of the user who registered “15F” is the special user Pa, “10F” The assignment will be changed to Unit No.

  FIG. 8 is a diagram showing an example of a stop floor displayed on the display device 16b of the B machine.

  In the security mode, the destination floors of users with different attributes are reassigned to different units. In the example of FIG. 8, “10F” is changed to be assigned to Unit B, and is displayed as a stop floor on the display device 16b of Unit B.

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

  FIG. 9 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 has registered the destination floor by operating the operation unit 14 of the landing destination floor registration device 13 on an arbitrary floor. At this time, an ID number for identifying the user is also registered by operating the operation unit 14.

  When the destination floor and the ID number are registered by the landing destination floor registration device 13, the hall call information including the destination floor and the registration floor is given to the registration control unit 23 of the group management control device 20 together with the ID number, as shown in FIG. Stored in the management table 23a (step S11).

  The assignment control unit 24 refers to the management table 23a and assigns the newly generated hall call information to the most appropriate car in each car (step S12). 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. In this case, in order to improve the operation efficiency, the same destination floor or the user's hall call information close to the destination floor is assigned to the same unit. A car to which hall call information is assigned is called an assigned car.

  Here, the allocation control unit 24 determines whether or not the security mode is set (step S13). This security mode is automatically switched according to the time zone. For example, in the time zone when the elevator usage frequency is high during the day, the security mode is OFF in order to give priority to the operation efficiency.

  If the security mode is OFF (No in Step S13), the assigned number determined in Step S12 is determined as the user's boarding number as it is, and the number of that number is displayed on the landing destination floor registration device 13 through the display control unit 26. Are displayed on the display unit 15 (step S14). Further, the destination floor of the user is displayed on the display device 16 corresponding to the assigned number as a stop floor of the number (step S15).

On the other hand, the security mode is switched to ON in order to give priority to security in the time zone where the elevator usage frequency is low, such as at night. Here, when the destination floor of the user is registered in the state where the security mode is ON, the assigned number is determined according to the attribute of the user. That is, users with the same attributes are assigned to the same unit. Therefore, users with different attributes do not ride on the same unit. However, if the security mode is switched ON immediately after the assigned number is determined (Yes in step S13 ), users with different attributes may get on the same number.

  Therefore, the attribute of the user who gets on the assigned number determined in step S12 is checked by the user attribute determination unit 22 (step S16). Specifically, the database 22a is searched based on the ID number of the user who gets on the assigned number machine, and it is determined whether the attribute of the user is Pa, Pb, or Pc.

  If the user attributes are the same, it is determined that there are no users with different attributes assigned to the assigned car (No in step S17), and the display control unit 26 assigns the current assigned car number to the landing destination floor registration device 13. Is displayed on the display unit 15 (step S20). The same applies when there are no other users, and it is determined that there is no boarding, and the number of the current assigned number is displayed on the display unit 15 of the landing destination floor registration device 13.

  On the other hand, if the user attributes are different, it is determined that there is a user with a different attribute on the assigned machine (Yes in step S17). In such a case, the allocation changing unit 25 changes the allocation of a user's machine other than the same attribute to another machine (step S18).

  In the example of FIG. 7, it is assumed that the general user Pb registers “10F” and is assigned to Unit A. At that time, “11F” and “15F” are assigned to the A machine, and if the attribute of the users is the special user Pa, “10F” is changed to the other machine. In addition, the change destination is the most suitable unit among each unit at that time.

  When there is an assignment change, the assigned number of the user in the management table 23a is updated to another number (step S19), and the number of the number is displayed on the display unit 15 of the landing destination floor registration device 13 ( Step S20). For example, in the case of changing from No. A to No. B, "No. B" is displayed on the display unit 15 of the landing destination floor registration device 13 shown in FIG.

  Further, the destination floor of the user is displayed as the stop floor of the relevant unit on the display device 16 corresponding to the unit after the change of allocation (step S21). FIG. 8 shows a display example after the allocation change, and “10F” is added as a stop floor to the display device 16b of Unit B.

  In this way, when the user switches from the normal operation mode that prioritizes operation efficiency to the security mode that prioritizes security, if a user with a different attribute is on board, the assignment is changed to another unit. The Therefore, it is possible to eliminate that the general user Pb and other users Pc get on the same machine as the special user Pa without preparing a dedicated machine for carrying only the special user Pa. You can drive with security.

  In the first embodiment, the security mode is automatically switched according to the time zone. However, a building administrator, an elevator maintenance worker, or the like is installed in the group management control device 20 at an arbitrary timing. It may be configured to be manually switched by operating a mode switch or the like (not shown).

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

  In the said 1st Embodiment, it was set as the structure which displays a stop floor on the display apparatus 16 installed in the landing of each unit, even when the security mode is set. However, when the stop floor is displayed on the display device 16, there is a problem that it is known where each unit goes. Therefore, in the second embodiment, the stop floor of each unit is hidden so that the security is improved.

  Since the basic apparatus configuration is the same as that in FIG. 1 in the first embodiment, processing related to stop floor display control will be described here.

  FIG. 10 is a flowchart partially showing the processing operation of the elevator group management system in the second embodiment.

  As described above, when the security mode is set, the assigned number is determined so that a user having the same attribute can be put on the same number, and the number of the assigned number is fixed on the display unit 15 of the landing destination floor registration device 13. The time is displayed (step S20).

  Here, the display control unit 26 provided in the group management control device 20 prohibits the display of the stop floor on the display device 16 of each unit so that the stop floor of each unit is not visible to the user (step) S22). As a result, it is possible to prevent the stop floor of each unit displayed on the display device 16 from going to a floor different from its own attribute. However, there is a problem that the car that you should ride is not understood.

  Therefore, when the destination floor and the ID number are re-registered in the landing destination floor registration device 13 as a confirmation operation of the car (Yes in Step S23), the display control unit 26 registers the number of the assigned car number for the user at the landing destination floor. The information is displayed again on the display unit 15 of the device 13 (step S24). As a result, even if the stop floor of each unit is not displayed, it is possible to confirm the vehicle that the driver should originally ride and to wait before the landing of that unit.

  In this way, when the security mode is set, by hiding the stop floor of each unit, it is possible to prevent the user from going to a floor having a different attribute and improve security. Furthermore, by providing a function for redisplaying the assigned number machine by the confirmation operation of the number machine, it is possible to cope even if the user forgets the number machine to be on.

(Third embodiment)
Next, a third embodiment will be described.

  In the said 1st Embodiment, it was set as the structure which registers an ID number with a user's destination floor with the hall destination floor registration apparatus 13, and judges a user's attribute from the ID number. On the other hand, in the third embodiment, the user attribute is recorded on the ID card possessed by the user, the information on the ID card is read at the landing and transferred to the group management control device 20. .

  FIG. 11 is a diagram illustrating a configuration of an elevator group management system according to the third embodiment. In addition, the same code | symbol is attached | subjected to the same part as FIG. 1 in the said 1st Embodiment, and the description shall be abbreviate | omitted.

  In the third embodiment, a card reader 31 is installed in the vicinity of the landing destination floor registration device 13 at the landing on each floor. The card reading device 31 is connected to the group management control device 20, reads the information on the ID card 32 in a non-contact manner, and transfers the information to the group management control device 20. In addition, although there exists an electromagnetic induction system etc. as a non-contact system, in this invention, it is not limited to the system in particular.

  FIG. 12 is a diagram showing an example of information recorded on the ID card 32.

  The ID card 32 is possessed by a user who uses the elevator in the building. In this ID card 32, an ID number for identifying the user and information on the attribute of the user are recorded. User attributes are defined by destination floors that can be registered, and are classified by Pa (special user), Pb (general user), and Pc (other users).

  In such a configuration, when the user registers the destination floor by operating the operation unit 14 of the landing destination floor registration device 13, the user possesses the card reading device 31 installed near the landing destination floor registration device 13. The information of the ID card 32 to be read is read and transferred to the group management control device 20 together with the hall call information including the destination floor.

  The group management control device 20 determines the assigned car number based on the hall call information including the destination floor, and checks the user attribute when the security mode is set. At this time, the user attribute determination unit 22 provided in the group management control device 20 determines whether the user attribute is Pa, Pb, or Pc based on the information of the ID card 32. The subsequent steps are the same as those in the first embodiment, and the assignment is changed according to the user's attribute to eliminate the user's attendance with different attributes (see FIG. 9).

  As described above, the attribute information is recorded on the ID card 32 possessed by the user, and the attribute information is read by the card reader 31 installed at the landing and transferred to the group management controller 20. As in the first embodiment, it is possible to drive while securing the security of the user by eliminating the use of users having different attributes in the security mode without using a dedicated machine.

  In the configuration of the third embodiment, the stop floor of each unit may be hidden when the security mode is set in combination with the second embodiment.

  According to at least one of the embodiments described above, it is possible to provide a group management system for elevators that can eliminate the riding of users having different attributes without using a dedicated machine, and can operate while ensuring security. it can.
