Description

  The present invention relates to an elevator control device, and more particularly to an elevator control device in which an operation mode of an operation control means for controlling the operation of a car can be switched between a normal operation mode and a maintenance operation mode.

  As this type of elevator control device, for example, one disclosed in Patent Document 1 has been proposed.

  In the elevator control device described in Patent Document 1, when the inspection notice switch and the inspection switch for maintenance operation switching are connected to the control circuit that controls the operation of the car and the inspection notice switch is turned on, the control is performed. The circuit displays on the display devices provided on the floors of each floor to notify the start of maintenance work. When the inspection switch is turned on, call registration is prohibited and elevator users are not allowed to enter the car. In addition to the prohibition, a display indicating that the inspection is being performed is displayed on each of the display devices.

In other words, the maintenance worker first turns on the inspection notice switch before starting the maintenance work to notify the elevator user that the maintenance work will start, and then turns on the inspection switch to turn on the elevator user's car. The maintenance work will be started by prohibiting entry into the car.
JP 2005-67838 A

  However, in the technique described in Patent Document 1, since the maintenance worker has to operate the two switches before starting the maintenance work, the work becomes complicated.

  In addition, when the inspection switch is turned on, all calls registered to prohibit elevator users from entering the car are released, so the user waiting for the arrival of the car at the landing can lift the elevator. There is a possibility that it cannot be used. On the other hand, if the maintenance worker waits until the registration of all calls is lost after turning on the check notice switch, and then turns on the check switch, a new passenger calls a new landing call while waiting. Is registered, there is a possibility that the waiting time of the maintenance worker increases and the maintenance work cannot be started smoothly.

  The present invention has been made in view of the above-described problems, and in particular, provides an elevator control device that allows a maintenance worker to smoothly start maintenance work while ensuring convenience for elevator users. The purpose is to do.

  The invention according to claim 1 is an operation control capable of switching an operation mode between a normal operation mode in which a car is normally operated in response to registration of a hall call and a car call and a maintenance operation mode in which the normal operation is stopped. An operation mode selection means for selectively outputting a maintenance operation selection signal for selecting a maintenance operation mode as an operation mode of the operation control means and a normal operation selection signal for selecting a normal operation mode as an operation mode of the operation control means; The elevator control device comprises an operation mode switching means for receiving a maintenance operation selection signal and a normal operation selection signal from the operation mode selection means, and the operation mode switching means has an operation mode of the operation control means. On the condition that the maintenance operation selection signal is received in the normal operation mode, registration of a new hall call is prohibited and The operation control means sequentially responds to the received hall call and car call to cancel the registration of all hall calls and car calls, and then the operation mode of the operation control means is switched to the maintenance operation mode. It is said.

  That is, according to the first aspect of the present invention, when the maintenance operation mode is selected by the maintenance operation mode selection means when the operation mode of the operation control means is the normal operation mode, the operation mode switching means registers a new hall call. The operation control means switches the operation mode of the operation control means to the maintenance operation mode after providing service for passengers who have already registered the hall call and waiting for the arrival of the car at the landing.

  After that, as in the invention described in claim 2, the switch to the maintenance operation mode is completed on condition that the operation mode switching means switches the operation mode of the operation control means to the maintenance operation mode. If the switching completion notifying means for notifying is activated, the maintenance worker can easily know that the switching to the maintenance operation mode has been completed by the operation of the switching completion notifying means.

  Preferably, as in the invention described in claim 3, operation state notifying means for notifying the operation state of the elevator is provided at each service floor, and the operation mode switching means receives the maintenance operation selection signal. After the registration of a new hall call is prohibited, if the elevator is in a normal operation stop state by sequentially operating the operation status notification means for the floor without a hall call, the elevator The passenger can easily know that the vehicle is in the operation stop state.

  More preferably, as in the invention described in claim 4, after the operation mode switching means receives the maintenance operation selection signal, the operation state notification means on each service floor notifies the stop of normal operation for a predetermined time and then newly If the registration of a special hall call is prohibited, the elevator user can be notified in advance of the suspension of normal operation.

  More preferably, as in the invention described in claim 5, the operation mode switching means for each service floor is provided on the condition that the operation mode switching means receives the normal operation selection signal when the operation mode is the maintenance operation mode. If the operation mode is switched to the normal operation mode after the start of the normal operation is notified for a predetermined time, the elevator user can be notified in advance of the resumption of the normal operation.

  Therefore, according to at least the first aspect of the present invention, when a maintenance operation selection signal is output from the operation mode selection means to the operation mode switching means, the operation mode switching means prohibits registration of a new hall call and controls operation. After the means responds to all existing hall calls, the operation mode of the operation control means is switched to the maintenance operation mode, so that maintenance work can be performed smoothly while maintaining the convenience of the elevator user. Will be able to start.

  In addition, according to the second aspect of the present invention, the maintenance worker can smoothly perform the maintenance work by notifying the maintenance worker that the switching to the maintenance operation mode is completed by the operation of the switching completion notification means. Will be able to start.

  Further, according to the inventions described in claims 3 to 5, the elevator user notifies the elevator user of the fact that the elevator is in the normal operation stop state or the advance notice of the operation mode switching, so that the elevator user receives the information. There is an advantage that it can be used for the use of the elevator and the convenience of the elevator user is further improved.

  FIG. 1 is a diagram showing an elevator control apparatus as a more specific embodiment of the present invention.

  As shown in FIG. 1, the elevator operation control device 1 includes landing operation panels 2a, 2b, and 2c provided at the landings of the service floors, a car operation panel 3 provided in the car, and an operation mode. Switching operation devices 4 are connected to each other. The operation control device 1 is arranged in a machine room when a machine room is provided at the top of the hoistway. Installed.

  Each hall operation panel 2a, 2b, 2c includes a car position indicator 5 for displaying the current position of the car, an operating state indicator 6 as an operating state notifying means for displaying the operating state of the elevator, and ascending and descending directions. Both or one of the hall call buttons 7a and 7b is provided. Specifically, the hall operation panel 2b of each intermediate floor excluding the upper and lower terminal floors of each service floor is provided with ascending and descending hall call buttons 7a and 7b, respectively, and the upper part of each service floor Only the landing call button 7b in the downward direction is provided on the landing operation panel 2a on the final floor, and only the hall call button 7a in the upward direction is provided on the landing operation panel 2c on the lowest floor among the service floors. When each hall call button 7a, 7b is pressed, a hall call signal corresponding to the floor where the hall call button 7a, 7b is installed and the direction of the hall call button 7a, 7b is output to the operation control device 1. It has come to be. Further, the car position indicator 5 is constituted by a so-called 7-segment LED for displaying numbers, while the operation state indicator 6 is constituted by a so-called liquid crystal display.

  The car operation panel 3 has a car position indicator 8 for displaying the current position of the car, a plurality of car call buttons 9 for outputting a car call signal to the operation control device 1, a door opening button 10a and a door closing button 10b. is doing. As is well known, each car call switch 9 is assigned a predetermined floor, and when one of the car call switches 9 is pressed, the floor assigned to the car call switch 9 is displayed. A car call signal for the destination floor is output to the operation control device 1. The car position indicator 8 has a so-called 7-segment LED for displaying numbers.

  On the other hand, the operation control device 1 switches the operation mode of the main control unit 13, a main control unit 13 that is an operation control unit that controls the operation of the car, a call registration control unit 14 that registers a call in the main control unit 13, and the main control unit 13. An operation mode switching control unit 15 that is an operation mode switching unit and a state display control unit 16 that controls the display of the operation state indicator 6 of each hall operation panel 2 are provided.

  The call registration control unit 14 registers the car call and the hall call in the main control unit 13 based on the hall call signal and the car call signal from the hall call buttons 7a and 7b and the car call buttons 9. .

  The main control unit 13 changes the operation mode between the normal operation mode in which the car is normally operated in response to the hall call and the car call registered by the call registration control unit 14 and the maintenance operation mode in which the normal operation is stopped. The operation mode switching control unit 15 switches and controls the operation mode of the main control unit 13.

  The operation mode switching operation device 4 selectively selects a maintenance operation selection signal for selecting the maintenance operation mode as the operation mode of the main control unit 13 and a normal operation selection signal for selecting the normal operation mode as the operation mode of the main control unit 13. A maintenance operation switch 11 serving as an operation mode selection means for outputting to the operation mode switching control section 15; a switching completion lamp 12 serving as a switch completion notification means that is turned on based on a command from the operation mode switching control section 15; have. That is, the maintenance operation switch 11 outputs a maintenance operation selection signal to the operation mode switching control unit 15 when the maintenance operation switch 11 is in the ON state, while the operation mode switching control is performed when the maintenance operation switch 11 is in the OFF state. A normal operation selection signal is output to the unit 15. When the operation control device 1 is provided in the machine room at the top of the hoistway, the operation mode switching operation device 4 is preferably installed in the machine room, and the operation control device 1 is installed in the hoistway or on a specific floor. It is desirable to install at the landing on a specific floor. Further, the operation control device 1 and the operation mode switching operation device 4 may be wirelessly connectable, and the operation mode switching operation device 4 may be configured to be portable.

  The operation mode switching control unit 15 switches the operation mode of the main control unit 13 according to the input from the maintenance operation switch 11, and the switch completion lamp 12 is switched according to the operation mode of the main control unit 13. In addition to turning on and off, the registration of the car call and the hall call to the main control unit 13 by the call registration control unit 14 is restricted, and the state display unit 16 of each hall operation panel 2 is set to a predetermined state via the state display control unit 16. Is to be displayed.

  FIG. 2 is a flowchart showing the control content of the operation mode switching control unit 15.

  More specifically, as shown in FIG. 2, the operation mode switching control unit 15 first sets the operation mode of the main control unit 13 to the normal operation mode (step S1), and each of the landing operation panels 2a, 2b, 2c. The character “normal operation” is displayed on the operation state display 6 (step S2), and then it is monitored whether the maintenance operation switch 11 is in an ON state, that is, whether a maintenance operation selection signal is received. (Step S3).

  Then, when the maintenance worker turns on the maintenance operation switch 11 before the maintenance work is started and the operation mode switching control unit 15 receives the maintenance operation selection signal, the operation mode switching control unit 15 passes through the state display control unit 16. Then, the characters “Normal operation” are blinked on the operation status display 6 of each hall operation panel 2 (step S4), and registration of a new hall call is prohibited after a predetermined time has elapsed since the display was started. (Steps S5 and S6). More specifically, the operation mode switching control unit 15 outputs a hall call registration prohibition command signal to the call registration control unit 14 in step S6, and a new hall call to the main control unit 13 by the hall call registration control unit 14 is performed. Prohibit registration.

  Then, the operation mode switching control unit 15 assigns 1 to the variable x (step S7), and determines whether or not hall calls in the up and down directions on the x floor are registered in the main control unit 13 ( Step S8). As a result, when neither the ascending and descending hall calls on the x floor are registered, the operation mode switching control unit 15 operates the driving state of the x floor hall operation panel via the state display control unit 16. The display 6 is switched from the blinking display of “normal operation” to the display of “inspection work” (step S9), and the floor number n of the upper terminal floor of each service floor is equal to the variable x. It is determined whether or not (step S10). In step S8, if at least one of the hall calls in the ascending direction and the descending direction on the x floor is registered, the process proceeds to step S10.

  In step S10, if the number of floors n of the upper terminal floor is different from the variable x in each service floor, the variable x is incremented by 1 and the process returns to step S8 (step S11). In step S10, each elevator If the number of floors n in the upper terminal floor is equal to the variable x, it is determined whether no ascending and descending hall calls are registered in all service floors (step S12). ) If at least one of the hall calls is registered, the process returns to step S7. That is, in steps S7 to S12, the operation mode switching control unit 15 monitors the presence / absence of a landing call on each service floor, and during that time the main control unit 13 responds by sequentially responding to the registered landing call and car call. The hall call and car call will be released in sequence.

  Then, the main control unit 13 responds to all registered hall calls and cancels all hall calls. In step S10, it is determined that neither the ascending and descending hall calls are registered on all service floors. In the case where the car call is not registered (step S13), the operation mode of the main control unit 13 is switched to the maintenance operation mode (step S14), and the switching completion lamp is displayed as the maintenance operation switching completion display. 12 is turned on (step S15), and it is monitored whether the inspection switch is in an OFF state, that is, whether a normal operation selection signal is received (step S16).

  In other words, the operation mode switching control unit 15 registers a new hall call on the condition that the operation mode switching control unit 15 receives the maintenance operation selection signal when the operation mode of the main control unit 13 is the normal operation mode. In this state, the main control unit 13 sequentially responds to the registered hall call and car call, and sequentially cancels the hall call and car call that responded. The operation mode switching control unit 15 switches the operation mode of the main control unit 13 to the maintenance operation mode on condition that registration of all hall calls and car calls is canceled. Further, the switch completion lamp 12 is turned on on the condition that the operation mode of the main control unit 13 is switched to the maintenance operation mode, and the maintenance worker is notified that the switching to the maintenance operation mode is completed. As a result, the maintenance worker starts the maintenance work.

  When the maintenance worker turns off the maintenance operation switch 11 after the maintenance work is completed and the operation mode switching control unit 15 receives the normal operation selection signal, the operation mode switching control unit 15 is connected via the state display control unit 16. The characters “inspection work” displayed on the operation status display 6 on each service floor are blinked (step S17), and after the predetermined time has elapsed since the blinking display is started, the process returns to step S1 to return to the main control unit 13. The operation mode is switched to the normal operation mode (step S18).

  Therefore, according to the present embodiment, when a maintenance operation selection signal is output from the operation mode switching operation device 4 to the operation control device 1, the arrival of the car is already registered while prohibiting registration of a new landing call. Service for passengers waiting at the landing, canceling all landing calls and car calls, and switching the operation mode of the main control unit 13 to the maintenance operation mode. The maintenance worker can start the maintenance work smoothly while ensuring the safety.

  In addition, after switching the operation mode of the main control unit 13 to the maintenance operation mode, the maintenance worker is notified by the switch completion lamp 12 that the switching to the maintenance operation mode is completed. Will be able to start maintenance work more smoothly.

  Furthermore, the elevator user can make use of the information for the use of the elevator by displaying the operation state of the elevator and the advance notice of the operation mode switching to the elevator user by the operation status indicator 6 of each service floor. There is an advantage that the convenience of the elevator user is further improved.

  In the present embodiment, a so-called liquid crystal display is used as the operation status indicator 6 of each service floor, and two types of characters “inspection work” and “normal operation” are used with the operation status indicator 6. However, it is possible to use a status indicator that displays only "inspection work" characters on the display board and the backlight. Is possible. In this case, the backlight is turned off when the operation mode of the main control unit 13 is the normal operation mode, while the backlight is turned on when the operation mode of the main control unit 13 is the maintenance operation mode, and the backlight blinks. It is good to make a notice of switching operation mode.
