Description

Destination floor control device and elevator operation method

The application is based on Japanese patent application 2017-119260, filed on 19.6.2017, and enjoys the priority of the application. This application is incorporated by reference in its entirety.

Technical Field

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

Background

As a building in which an elevator is installed, there is a building using a destination floor Control system (also referred to as dcs (destination Control system)) of a hall.

The destination stratum control system of the elevator waiting hall is a system as follows: when a user registers a destination floor of a destination from a destination floor registration device of a hall provided in each floor, a number on which the user takes is allocated from an elevator group. This can improve the operation efficiency compared to the normal group management.

However, when an abnormality occurs in the destination floor control system of the elevator hall due to a failure of the destination floor registration device of the elevator hall or the like, the call registration from the elevator hall cannot be performed, and therefore, the user who is present at the failure occurrence floor where the failure has occurred in the destination floor registration device of the elevator hall cannot use the elevator. Therefore, conventionally, when an abnormality occurs in the destination floor registration system of a lobby, all elevators targeted for the destination floor registration device of the lobby having a failure are operated so as to shift to each floor operation. Thus, the user who is present at the trouble occurrence floor can use the elevator without forgetting the trouble occurrence floor.

However, in the conventional operation method, since the layer in which the call is not generated is also stopped, there is a problem that an unnecessary stop layer in which the call is not generated is increased and the service to the user is reduced. Further, depending on the building, there are floors that are set not to stop from the viewpoint of safety. When the elevator stops at this floor, any elevator user can get on or off the floor, and there is a problem that the safety level of the entire building is lowered.

Detailed Description

A configuration of a destination floor registration system of a lobby according to an embodiment will be described with reference to fig. 1.

As shown in fig. 1, four machines, i.e., a machine a, a machine B, a machine C, and a machine D, are set in the building according to the embodiment. The hall destination layer registration system 1 (destination layer registration system) according to the embodiment includes a destination layer control device (hereinafter, referred to as a "DCS control device") 10, and the DCS control device 10 is connected to hall destination

layer registration devices

11, 12, 13, 14, and 15 (destination layer registration devices) provided in respective floors. The system also includes an a-machine control device 20 for controlling a machine a, a B-machine control device 30 for controlling a machine B, a C-machine control device 40 for controlling a machine C, and a D-machine control device 50 for controlling a machine D. The a-, B-, C-, and D-

plane control devices

20, 30, 40, and 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 car number assignment unit 18.

The failure monitoring unit 16 is connected to the destination floor registration devices 11 to 15 in each hall, and performs heartbeat monitoring by periodically (on the order of several times during 1 second) transmitting a failure monitoring signal (heartbeat signal) to the destination floor registration devices 11 to 15 in each hall. The destination floor registration devices 11-15 of the elevator hall which do not respond to the fault monitoring signal determine that a fault has occurred.

When any one of the destination floor registration devices 11 to 15 in the lobby has failed, the call registration unit 17 changes the destination floors of all the elevators under the jurisdiction of the destination floor registration device in the lobby having failed to the reference floor. In addition, the call is changed to stop at the failure occurrence layer.

The car assignment unit 18, upon receiving a destination floor registration signal from the destination floor registration devices 11 to 15 in the lobby, assigns any of the a, B, C, and D cars based on the destination floor registration signal, and outputs an operation command to the corresponding

car control devices

20, 30, 40, and 50.

Next, the operation of the present embodiment will be described with reference to fig. 2 and 3.

As shown in fig. 2, it is assumed that the destination floor registration device 14 of the lobby now at level 4 has failed. Further, the reference layer is set to 1 layer.

In the flowchart shown in fig. 3, the failure monitoring unit 16 of the DCS control device 10 constantly monitors the failures of the destination floor registration devices 11 to 15 in the lobby of each floor (ST 1). That is, the target floor registration devices 11 to 15 in the lobby transmit heartbeat signals at a fixed cycle of several times in a period of 1 second, and monitor whether or not there is a response signal to the heartbeat signals. When the failure monitoring unit 16 does not receive the response signal, it determines that a failure has occurred in the destination floor registration devices 11 to 15 of the lobby that has not responded (ST 2). Here, since there is no response from the hall destination layer registration device 14 of 4 floors, it is recognized that a failure has occurred in the hall destination layer registration device 14 of 4 floors.

When recognizing the destination floor registration device 14 in the hall where the trouble has occurred, the trouble monitoring unit 16 sends a call registration signal to the call registration unit 17, assuming that there is a destination floor registration from the destination floor registration device 14 in the hall where the trouble has occurred. Thus, the call registration unit 17 registers a call from the 4 th floor with the reference floor as the destination floor. The car assignment unit 18 selects the best car to be able to respond to the call, and outputs an operation command to the corresponding car control devices 20 to 50 (ST 3). Thus, the number assigned with the call stops at the 4 th floor (ST4), and then proceeds to the reference floor (ST5, ST 6). On the reference layer, the user is guided to use another car (ST 7). Thus, even if the destination floor registration device 14 in the lobby of 4 floors fails and the destination floor registration cannot be performed, the car number can be reliably assigned and moved to 4 floors, so that the user does not forget to 4 floors.

< other examples >

In the above-described processing procedure, the call registration unit 17 performs call registration so that all the machines are stopped at the failure occurrence floor in the operation direction toward the reference floor via the failure occurrence floor where the failure has occurred in the hall destination floor registration devices 11 to 15. If the destination floor is in the direction of the reference floor (1 floor) (YES in ST3), the fault occurrence floor is stopped for a user to board and the floor is moved to the 1 floor as the reference floor (ST5, ST 6).

For example, a building with 5 floors (B5 floors) to 30 floors below ground is assumed. When the current car position of the car B is 15 floors and a failure occurs in 4 floors during the ascending operation to 30 floors, the call registration unit 17 performs call registration as a case where a call is generated from 4 floors to 1 floor (reference floor) as the destination floor. Therefore, during the descending operation from the 30 th floor to the reference floor, the user stops at the 4 th floor and rides on the floor, and then the user travels to the 1 st floor as the reference floor. When a failure occurs in the underground 3-layer while the underground 5-layer is stopped, the call registration unit 17 performs call registration as a case where a call is made from the underground 3-layer to the target layer 1 (reference layer). Thus, the user must stop at the 3 th floor below the ground to get on the floor, and then travel to the 1 st floor as the reference floor.

As described above, according to the present embodiment, whether or not the destination floor registration devices 11 to 15 in the hall provided in each floor have failed is monitored. When a failure of the destination floor registration devices 11 to 15 in the lobby is detected, call registration is performed as a case where a registration from the failure occurrence floor where the failed destination floor registration devices 11 to 15 in the lobby is installed to the destination floor of 1 floor as a reference floor occurs. Then, all the machines are stopped at the fault occurrence floor in the running direction of the fault occurrence floor which has failed through the destination floor registration devices 11 to 15 of the elevator hall to the reference floor.

Therefore, the user can surely move to the reference layer without forgetting the failure occurrence layer.

Further, when the destination floor registration devices 11 to 15 in the lobby have failed, the stop to the unnecessary floors can be eliminated as compared with the conventional operation in which all the cars are stopped at each floor, and therefore, the elevator can be operated efficiently, and the convenience of the user is improved.

Further, since the building does not stop at a floor set to stop from the viewpoint of safety, it is possible to prevent a problem that the safety level of the entire building is lowered.
