Description

  Embodiments described herein relate generally to a destination floor control device and an elevator operation method.

  Some buildings in which elevators are installed employ a landing destination floor control system (also referred to as DCS (Destination Control System)). This landing destination floor control system is a system that allocates the number of elevators that the user gets on from the elevator group when the user registers the target destination floor in advance from the landing destination floor registration device installed at the landing on each floor. Thereby, operation efficiency can be improved compared with normal group management.

Japanese Patent Laid-Open No. 7-53144

  By the way, if an abnormality occurs in the landing destination floor control system due to a failure of the landing destination floor registration device, call registration from the landing becomes impossible, so the users existing on the failure floor where the landing destination floor registration device has failed You will not be able to use the elevator. Therefore, conventionally, when an abnormality occurs in the landing destination floor registration system, all elevators targeted by the failed landing destination floor registration device are operated so as to shift to each floor operation. Thereby, the user who exists in a failure occurrence floor can use an elevator, without being left in a failure occurrence floor.

  However, since the conventional operation method also stops at a floor where no call is generated, there is a problem that the number of useless floors where a call is not generated increases and the service to the user is reduced. Also, some buildings have floors that are set not to stop for security reasons. If you stop at that floor as well, any elevator user can get on and off, and the security level of the entire building is reduced.

  This invention is made | formed in view of the said situation, and it aims at providing the destination floor control apparatus and elevator operation method which prevented the security fall of the building considering the convenience of the elevator user.

  An embodiment for achieving the above object is a destination floor control device that allocates a number of machines based on a destination floor registered from a landing destination floor registration device installed at a landing on each floor, wherein the landing destination floor registration device includes: When a failure is detected in the failure monitoring unit for monitoring whether or not a failure has occurred and the landing destination floor registration device is detected, from the failure occurrence floor where the failure destination floor registration device is installed to the reference floor A call registration unit that performs call registration as a destination floor registration has occurred.

The whole figure showing composition of a hall destination floor registration system provided with a destination floor control device concerning an embodiment. Explanatory drawing of operation | movement when a failure generate | occur | produces in the landing destination floor registration apparatus with the structure shown in FIG. The flowchart which shows the process sequence at the time of the failure generation in the hall destination floor registration system which concerns on embodiment.

  A configuration of a landing destination floor registration system according to an embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 1, four units of Unit A, Unit B, Unit C, and Unit D are set in the building of the embodiment. The landing destination floor registration system 1 according to the embodiment includes a destination floor control device (hereinafter referred to as “DCS control device”) 10, and the DCS control device 10 includes a landing destination floor registration device 11 provided on each floor, 12, 13, 14, and 15 are connected. Moreover, the A machine control apparatus 20 which controls the A machine, the B machine control apparatus 30 which controls the B machine, the C machine control apparatus 40 which controls the C machine, and the D machine control apparatus 50 which controls the D machine I have. The No. A control device 20, the No. B control device 30, the No. C control device 40, and the No. D control device 50 are connected to the DCS control device 10 and managed by the DCS control device 10.

  The DCS control device 10 includes a failure monitoring unit 16, a call registration unit 17, and a machine number allocation unit 18.

  The failure monitoring unit 16 is connected to each landing destination floor registration device 11 to 15 and periodically transmits a failure monitoring signal (heartbeat signal) to each landing destination floor registration device 11 to 15 (about several times per second). And execute heartbeat monitoring. It is determined that a failure has occurred for the landing destination floor registration devices 11 to 15 that do not respond to the failure monitoring signal.

  When a failure occurs in any of the landing destination floor registration devices 11 to 15, the call registration unit 17 changes the destination floor of all the units managed by the landing destination floor registration device in which the failure has occurred to the reference floor. . In addition, the call is changed to stop at the failure floor.

  Upon receiving the destination floor registration signal from the landing destination floor registration devices 11 to 15, the car allocation unit 18 allocates any one of A machine, B machine, C machine, and D machine based on the destination floor registration signal. An operation command is output to the machine controller 20, 30, 40, 50.

  Next, the operation of the present embodiment will be described with reference to FIGS.

  As shown in FIG. 2, it is assumed that a failure has occurred in the fourth-floor landing destination floor registration device 14. The reference floor is set to the first floor.

  In the flowchart shown in FIG. 3, the failure monitoring unit 16 of the DCS control device 10 constantly monitors failures of the landing destination floor registration devices 11 to 15 on each floor (ST1). That is, a heartbeat signal is transmitted to the landing destination registration devices 11 to 15 at a constant cycle of several times per second, and it is monitored whether or not there is a response signal to the heartbeat signal. When the failure monitoring unit 16 does not receive a response signal, it is determined that a failure has occurred in the landing destination floor registration devices 11 to 15 having no response (ST2). Here, since there is no response from the fourth-floor landing destination floor registration device 14, it is recognized that a failure has occurred in the fourth-floor landing destination floor registration device 14.

  When the landing destination floor registration device 14 in which the failure has occurred is recognized, the failure monitoring unit 16 assumes that the destination floor registration has been made from the landing destination floor registration device 14 in which the failure has occurred, and then calls the call registration unit 17. Send a call registration signal. Thereby, the call registration part 17 registers the call which makes a reference | standard floor a destination floor from the 4th floor. The number assignment unit 18 selects an optimum number that can respond to a call and outputs an operation command to the corresponding number control devices 20 to 50 (ST3). As a result, the unit to which the call is assigned stops on the fourth floor (ST4) and then travels to the reference floor (ST5, ST6). On the reference floor, the user is guided to use another unit (ST7). As a result, even if the fourth-floor landing destination floor registration device 14 breaks down and registration of the destination floor becomes impossible, it is possible to reliably allocate the machine and go to the fourth floor, so that the user is left on the fourth floor. There is nothing.

<Other examples>
In the above processing procedure, the call registration unit 17 stops all the units at the failure occurrence floor in the driving direction toward the reference floor via the failure occurrence floor where the failure has occurred in the landing destination floor registration devices 11 to 15. Call registration. If the destination floor is in the direction of the reference floor (first floor) (ST3 YES), it stops at the failure occurrence floor, puts a user on it, and travels to the first floor, which is the reference floor (ST5, ST6).

  For example, a building on the 5th basement (B5 floor) to 30th floor is assumed. If the current car position of Unit B is on the 15th floor and a failure occurs on the 4th floor during ascending operation up to the 30th floor, the call registration unit 17 sets the destination floor from the 4th floor to the 1st floor (reference floor) Registers a call as if it occurred. Therefore, at the time of the descent operation from the 30th floor toward the reference floor, the vehicle stops on the fourth floor, and after the user is placed, it travels to the first floor which is the reference floor. In addition, when a failure occurs on the third basement floor while stopping on the fifth basement floor, the call registration unit 17 registers the call as a call having the first floor (reference floor) as the destination floor from the third basement floor. Thus, the vehicle always stops on the third basement floor and puts a user on it, and then travels to the first floor which is the reference floor.

  Thus, according to the present embodiment, it is monitored whether or not a failure has occurred in the landing destination floor registration devices 11 to 15 installed at the landings on each floor. When a failure of the landing destination floor registration devices 11-15 is detected, the destination floor registration from the failure occurrence floor where the failure has occurred to the reference floor to the first floor is installed. Call and register as if this occurred. And in the driving | operation direction which goes to a reference | standard floor via the failure occurrence floor where the failure occurred in the landing destination floor registration apparatuses 11-15, all the units were stopped at the failure occurrence floor.

  For this reason, the user can be surely moved to the reference floor without being left on the floor where the failure occurred.

  In addition, when a failure occurs in the landing destination floor registration devices 11-15, compared to the conventional operation in which all the units are stopped at each floor, there is no need to stop to unnecessary floors, so efficient operation is possible. As a result, user convenience is improved.

  Furthermore, since it does not stop in the floor set not to stop on security, the malfunction that the security level of the whole building falls can be prevented.

  As mentioned above, 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 spirit 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.
