Description

  Embodiments described herein relate generally to an elevator system including a landing destination floor registration device.

  Generally, a hall call button for registering a hall call is installed at a hall on each floor of a building. When the elevator user operates this hall call button, the car responds to the registration floor of the hall call. When the user gets into the car and operates the destination floor button on the car operation panel, the destination floor is registered, and the car moves to the destination floor.

  In recent years, apart from the above-described hall call buttons, an elevator system including a hall destination floor registration device (HDC: Hall Destination Controller) that can directly designate a destination floor at a hall has been put into practical use. Such an elevator system is called a “destination floor control system (DCS)”. The DCS selects an optimal car from a plurality of cars based on the destination floor registered by the user at the boarding area, and responds to the boarding area. In this case, transport efficiency is improved by letting users on the same destination floor get on the same car.

  Here, the DCS in which the landing destination floor registration devices are installed on all floors is referred to as “full DCS”. In full DCS, the destination floor can be registered at the landing on each floor, so there is no need for a destination floor button in the car.

JP 2013-18585 A

  Usually, when an elevator is installed, a worker may move equipment between floors with equipment in the car. However, in DCS, since a normal destination floor button is not installed in the car, an operator cannot move to each floor.

  In addition, DCS-related equipment (such as HDC) is often not installed during construction. This is because if a related device is installed, a tool or the like may collide and be damaged. Therefore, it is common that the control panel itself to which the DCS related equipment is connected does not start during construction. Here, if any operation for driving the car is performed in a state where the DCS is not activated, it is detected as an abnormality of the DCS.

  The problem to be solved by the present invention is to provide an elevator system capable of operating a car as usual and using it for construction work even when the DCS is not activated.

  An elevator system according to an embodiment performs group management of a plurality of passenger cars and controls the operation of each passenger car based on a destination floor registered by a landing destination floor registration device installed at a landing on each floor.

The elevator system includes instruction means, operation mode switching means, and operation control means. The instructing means instructs to use any of the cars in the car during construction. The operation mode switching means switches the work use target car in each of the cars from the group management to the work operation mode when the instruction means instructs to use the work. The operation control means, when the operation control using each landing destination floor registration device is not normally activated, and when the operation mode switching means is switched to the construction operation mode, each landing destination floor The operation of the car to be used for construction is controlled according to the operation of the operation button for work while ignoring the abnormality related to the operation control using the registration device.

The work operation button 26 for work includes a destination floor button for designating a destination floor. Normally, the inspection box 25 is locked, and the key of the inspection box 25 is managed by a building manager or the like. Therefore, a general user cannot operate the operation button 26 for work in the inspection box 25.

  A work use switch 28 is provided on the operation panel 27. The construction use switch 28 is an instruction means for instructing an operator to use the car 21 during construction. When the construction use switch 28 is turned on, the construction operation mode is switched to operate the car 21 for construction use. The driving operation button 26 for work is used for the driving operation at that time.

  FIG. 4 is a diagram showing the configuration of the elevator system. Here, a configuration in which three elevators (cars) are group-managed is shown. The same parts as those in FIG.

  The elevator system in the present embodiment includes car control devices 31a, 31b, 31c and a group management control device 32 connected to these car control devices 31a, 31b, 31c.

  The car control devices 31a, 31b, and 31c are provided corresponding to the cars 21a, 21b, and 21c. The car control devices 31a, 31b, and 31c perform control by a single car including drive control of a hoisting machine (not shown) and door opening / closing control.

  A display 13a is connected to the car control device 31a. The indicator 13a is installed in the vicinity of the landing door of the car 21a, and displays the destination floor, the driving direction, and the like of the car 21a.

The indicator 13b is installed near the landing door of the car 21b, and displays the destination floor, the driving direction, and the like of the car 21b. The indicator 13c is installed near the landing door of the car 21c, and displays the destination floor, the driving direction, and the like of the car 21c.

  In the example of FIG. 1, only one display 13a, 13b, 13c is shown for convenience, but in reality, the displays 13a, 13b, 13c are installed at the landings on each floor.

  At each hall, at least one hall destination floor registration device 12 is installed. As described with reference to FIG. 1, the landing destination floor registration device 12 is a device for a user to register a destination floor at the landing. When the destination floor is registered by the hall destination floor registration device 12, the hall call information including two sets of information of the destination floor and the registered floor (the floor on which the destination floor registration operation has been performed) is group management controlled. Sent to device 32.

  When the group management control device 32 receives the hall call information, it assigns the hall call information to the optimum car among the cars 21a, 21b, 21c. A car to which hall call information is assigned is called an “assigned car”. When the assigned car is determined, the name of the assigned car is displayed on the display unit 12b of the landing destination floor registration device 12 operated by the user. Controlling the operation of the cars 21a, 21b, 21c using the landing destination floor registration device 12 (group management control) is called “DCS”.

  The group management control device 32 is a device that comprehensively controls the operation of the cars 21a, 21b, and 21c. The group management control device 32 has the above-described DCS function. Further, as shown in FIG. 5, the group management control device 32 includes an operation mode switching unit 32a and an operation control unit 32b as functions for realizing an operation under construction.

  The operation mode switching unit 32a switches the work use target cars in the passenger cars 21a, 21b, and 21c from the group management to the work operation mode when an instruction to use the work is given by operating the work use switch 28.

  When the operation control unit 32b is switched to the construction operation mode, the operation control unit 32b is provided in the work use target car ignoring the abnormality (DCS abnormality) related to the operation control using the landing destination floor registration device 12 of each floor. The operation of the car is controlled according to the operation of the operation button 26 for work.

  Next, the operation of this embodiment will be described.

  In addition, the process shown by the following flowcharts is performed when the group management control apparatus 32 which is a computer reads a predetermined program.

  FIG. 6 is a flowchart showing the operation of the group management control device 32 during construction operation.

  Now, it is assumed that the elevator is being installed, and the operation is stopped, for example, on the reference floor with the cars 21a, 21b, 21c being opened. An operator gets into an arbitrary car (referred to as car No. A car 21a) and unlocks the key of the check box 25 shown in FIGS. In the inspection box 25, an operation button 26 for work and a work use switch 28 are provided.

  When the work use switch 28 is turned on (Yes in step S101), the operation mode switching unit 32a of the group management control device 32 selects the car on which the work use switch 28 is operated as the work use target car (step). S102). In this case, since the construction use switch 28 in the car 21a of the A-unit is operated, the car 21a is selected as a construction use target car.

  The operation mode switching unit 32a switches the car 21a selected as the construction use target car from the group management and switches to the construction operation mode (step S103). “Separate from group management” means to remove from the DCS operation control executed by the group management control device 32.

  Here, when switching to the construction operation mode, the operation control unit 32b confirms whether or not general devices other than the DCS-related devices are in a normal state (step S104).

  The “DCS-related device” is a device necessary for DCS operation control, such as the landing destination floor registration device 12. The group management control device 32 can determine whether or not it is in a normal state from the presence or absence of signals output from these DCS-related devices.

  “General equipment other than DCS-related equipment” refers to equipment that is necessary for normal operation control and is not directly related to DCS operation control. For example, the display 23 in the car 21, the door opening button 24a, the door closing button 24b, various operation buttons 26 and 28 on the operation panel 27 provided in the inspection box 25, and the like. The group management control device 32 can determine whether or not it is in a normal state based on the presence or absence of signals output from these general devices.

  If the general equipment is in a normal state, it is possible to control the operation of the car 21a selected as a construction target car as a car alone. However, during construction, the DCS is not activated because the landing destination floor registration device 12 necessary for DCS is not installed at the landing, or even though it is installed at the landing, it is not connected to the group management control device 32. . If any driving operation is performed in such a state, it is detected as an abnormality of DCS.

  Therefore, if the general equipment is in a normal state (Yes in step S104), the operation control unit 32b controls the operation of the car 21a according to the operation of the operation operation button 26 for work ignoring the abnormality of the DCS. (Step S105). That is, normally, when any operation is performed in a state where the DCS is not activated, it is detected as an abnormality of the DCS, but when the car is operated alone in the construction operation mode, the abnormality of the DCS is ignored. .

  On the other hand, when any abnormality is detected in the general equipment in step S104, the operation control unit 32b prohibits the operation of the car 21a selected as the construction use target car (step S106). At this time, the fact that the vehicle cannot be driven due to an abnormality is displayed on the display 13a at the hall corresponding to the car 21a or the display 23 in the car 21a (step S107).

  FIG. 7 shows a display example when the operation of the car 21a is prohibited. When such an abnormality is displayed, it is necessary to immediately check the abnormal part. When the construction use switch 28 is operated again after the normal state can be restored, the processing from step S101 is repeated.

  As described above, according to the present embodiment, the car on which the work use switch 28 is operated is selected as the work use target car, is separated from the group management, and is switched to the work operation mode. In the construction operation mode, the abnormality of the DCS is ignored, so that even when the DCS is not activated, the operation operation button 26 for work in the car can be operated so that each floor can be moved freely. Become.

  Even if the DCS abnormality is ignored, if there is any abnormality in general equipment other than the DCS-related equipment, the operation of the car is prohibited, so that the safety of workers can be protected.
