Description

  The present invention relates to an elevator group management system.

  As an elevator group management system, one having a hall operation panel has been proposed. According to this group management system, when a destination floor is input on the hall operation panel, an elevator to which a destination call corresponding to the destination floor is assigned is selected from a plurality of elevators. At this time, a symbol or the like indicating the assigned elevator is displayed on a display in the vicinity of the hall operating panel. By this display, the user who operates the hall operating panel can confirm the elevator to be boarded.

  On the other hand, a control method has been proposed in which an elevator call is invalidated when a predetermined switch is operated. According to this control method, the operation of the elevator can be prevented from being unexpected by the maintenance staff (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 62-147669

  Consider a case where the switch of the control method is applied to the group management system as an independent operation switch. In this case, when the independent operation switch is operated, the elevator to which the destination call is assigned may be immediately excluded from the group management target. In this case, the destination call is assigned to another elevator.

  However, the user who operated the hall operating panel cannot confirm that the elevator to be boarded has been changed. For this reason, the user may not be able to get on an elevator traveling to a desired destination floor.

  The present invention has been made to solve the above-described problems, and its purpose is to be used for an elevator to which a destination call corresponding to a desired destination floor is assigned even when the elevator is independent from group management. It is to provide a group management system for elevators that can be used by passengers.

  The elevator group management system according to the present invention is an elevator that assigns a destination call corresponding to a destination floor from a plurality of elevators when the destination floor is designated by operating a hall operation panel provided at the elevator hall. Determining means for determining the vehicle, operating means provided corresponding to each of the plurality of elevators, and when the operating means is operated, the elevator corresponding to the operated operating means is assigned a destination call by the determining means. Control means for responding to the destination call before making the elevator independent of the control of the determining means.

  According to the present invention, even when an elevator is made independent of group management, a user can be put on an elevator to which a destination call corresponding to a desired destination floor is assigned.

In the lower part of the sliding door 3f, an independent operation switch 3c, a switch with a driver, and an emergency stop switch are provided.

  In the present embodiment, the destination floor is designated by the destination floor registration button 1a for each user. At this time, the destination button detecting means 1b transmits information regarding the operated floor of the hall and the destination floor corresponding to the operation content of the destination floor registration button 1a as a destination call to the assigned number determining means 2a. The assigned number machine determination means 2a determines an elevator (number machine) to which the destination call is assigned from among a plurality of elevators.

  Thereafter, the assigned number determining unit 2a transmits an assigned number command corresponding to the determined number to the assigned number display unit 1c. The assigned car display means 1c displays a destination floor and a symbol indicating the assigned elevator on the display 1d for a predetermined time based on the assigned car command.

  When the destination button 3b is operated in the car 3, the destination button detection means 3d transmits information related to the destination floor corresponding to the operation content of the destination button 3b to the destination floor registration means 4b. The destination floor registration means 4b registers a car call corresponding to the destination floor.

  When the independent operation switch 3c is operated in the car 3, the independent operation switch detection unit 3e transmits information indicating that the independent operation switch 3c has been operated to the operation mode management unit 4c. The operation mode management means 4c switches the operation of the elevator to the independent operation. In the independent operation, the elevator is independent from the control of the group management device 2. At this time, the independent operation switch operation floor storage means 4d stores the floor on which the independent operation switch 3c is operated.

Next, the operation of the group management system when the independent operation switch 3c is operated will be described with reference to FIG.
FIG. 6 is a flowchart for explaining the operation of the elevator group management system according to Embodiment 1 of the present invention.

  First, when the maintenance person operates the independent operation switch 3c in step S1, the process proceeds to step S2. In step S <b> 2, the car operation control unit 4 a determines whether or not destination call assignment by operation of the hall operating panel 1 is detected.

  If no destination call assignment has been detected, the process proceeds to step S3. In step S3, the operation mode management means 4c immediately shifts the elevator to the independent operation.

  On the other hand, if the assignment of the destination floor is detected in step S2, the process proceeds to step S4. In step 4, the car operation control means 4a confirms the presence / absence of another elevator that is a maintenance target. If there is another elevator that is a maintenance target, the process proceeds to step S5. In step S5, the operation moves to another elevator maintenance operation.

  On the other hand, if there is no other elevator that is the maintenance target in step S4, the process proceeds to step S6. In step S6, the independent operation switch operation floor storage means 4d stores the floor on which the independent operation switch 3c is operated. Thereafter, the operation proceeds to step S7, and the car operation control means 4a prohibits the assignment and registration of new calls other than the already assigned calls as the prohibiting means.

  Thereafter, the process proceeds to step S8, and the car operation control means 4a causes the elevator to respond to the final car call. Then, it progresses to step S9 and the car operation control means 4a makes an elevator drive to the floor memorize | stored in the independent operation switch operation floor memory | storage means 4d. Then, it progresses to step S3 and the operation mode management means 4c makes an elevator transfer to independent operation.

  According to Embodiment 1 described above, when a destination call is assigned to a corresponding elevator when the independent operation switch 3c is operated, the elevator calls the destination call before the independent operation is started. Respond to. For this reason, even when making an elevator independent from group management, a user can be boarded in an elevator to which a destination call corresponding to a desired destination floor is assigned. Therefore, there is no need to worry about the timing when the maintenance staff operates the independent operation switch 3c.

  Further, after the independent operation switch 3c is operated, call assignment and registration to the elevator corresponding to the operated independent operation switch 3c is prohibited. For this reason, the waiting time for maintenance personnel can be minimized. That is, it is possible to minimize a decrease in work efficiency of maintenance personnel.

  In addition, the elevator travels to the floor stored in the independent operation switch operation floor storage means 4d after responding to the final car call. For this reason, the maintenance staff can start the independent operation of the elevator from the floor where maintenance is desired.

  It is not necessary to limit the arrangement of the independent operation switch 3c to the car 3. For example, you may arrange | position the independent operation switch 3c corresponding to each elevator in each hall.
