Embodiment 1 FIG.
FIG. 1 is a schematic diagram illustrating an example of the structure of an elevator.

  As shown in FIG. 1, the elevator 1 includes a hoistway 2, a hoisting machine 3, a rope 4, a basket 5, and a counterweight 6. The hoistway 2 is formed, for example, so as to penetrate each floor of a building (not shown). The hoisting machine 3 is provided, for example, in a machine room (not shown). The rope 4 is wound around the hoisting machine 3. The basket 5 and the counterweight 6 are suspended in the hoistway 2 by the rope 4. The basket 5 and the counterweight 6 move up and down when the hoisting machine 3 is driven.

  As shown in FIG. 1, a fire fighting facility 7 is provided in the hoistway 2. The fire fighting equipment 7 is, for example, a smoke detector. The fire fighting equipment 7 is attached to a position corresponding to the top floor of the building in the hoistway 2, for example.

  As shown in FIG. 1, the elevator 1 has, for example, a landing entrance 8, a firefighting equipment inspection port 9, an express zone rescue exit 10, and a pit entrance 11 as openings that communicate with the hoistway 2. The hall entrance 8 is an entrance for a user of the elevator 1 to get on and off the cage 5. The fire equipment inspection port 9 is an opening for checking the fire equipment 7 from the landing. The express zone rescue exit 10 is an opening provided on the floor where the cage 5 does not stop at normal times. The pit entrance 11 is an entrance that leads to the pit portion of the hoistway 2. Doors are provided at the landing entrance 8, the firefighting equipment inspection port 9, the express zone rescue exit 10, and the pit entrance 11.

  The elevator 1 is provided with a plurality of safety switches constituting a safety circuit. Safety switches include internal safety switches and external safety switches. Examples of the internal safety switch include a governor switch, an emergency stop device switch, an upper limit switch, and a lower limit switch. The external safety switch is, for example, a switch provided on the door of the firefighting equipment inspection port 9, the door of the express zone rescue exit 10, the door of the pit entrance 11 or the like. The contacts of the external safety switch are closed when the corresponding door is closed, for example. The contacts of the external safety switch are opened, for example, when the corresponding door is opened.

  FIG. 2 is a configuration diagram showing an example of the configuration of the notification system in the first embodiment. The contacts indicated by letters in the figure are the contacts of the safety switch.

  As shown in FIG. 2, the notification system includes a control device 12, a remote monitoring device 13, an external interface device 14, a landing notification device 15, an in-car notification device 16, and an in-car operation panel 17. The control device 12 includes an operation control unit 18 and a notification control unit 19. The external interface device 14 has a switch state detection unit 20. The control device 12, the remote monitoring device 13, and the external interface device 14 are provided in the building where the elevator 1 is installed. The hall alarm 15 is provided at a hall on each floor of a building, for example. The landing alarm 15 may be provided on a wall surface near the pit entrance 11, for example. The in-car alarm 16 and the in-car operation panel 17 are provided on the wall surface in the car 5, for example.

  As the hall alarm 15, for example, at least one of a liquid crystal display, an indicator, a speaker, an intercom and the like is used. For example, at least one of a liquid crystal display, an indicator, a speaker, an intercom, and the like is used as the in-car alarm 16. The in-car operation panel 17 is provided with, for example, a door opening button, a door closing button, a destination floor button, and the like.

  As shown in FIG. 2, the control device 12 is electrically connected to the safety circuit of the elevator 1. The control device 12 is electrically connected to the contacts of each safety switch. The contact X is a contact of the internal safety switch. Contacts A, B and C are contacts of the external safety switch. The contact A is, for example, a switch contact provided on the door of the firefighting equipment inspection port 9. The contact B is, for example, a switch contact provided on the door of the express zone rescue exit 10. The contact C is, for example, a switch contact provided on the door of the pit entrance 11.

  As shown in FIG. 2, the contact X is connected to a power source. The contact A is connected in series with the contact X. The contact B is connected in series with the contact A. The contact C is connected in series with the contact B. That is, all the safety switches are connected in series so that an external safety switch is provided downstream of the internal safety switch in the current flow.

  The control device 12 has, for example, a connector (not shown) for electrical connection with each contact. The external interface device 14 is detachably attached to the control device 12 so as to relay, for example, between the contacts of each safety switch and the connector of the control device 12. That is, the control device 12 is electrically connected to the contacts of each safety switch via the external interface device 14.

  The operation control unit 18 controls the movement of the basket 5 by driving the hoisting machine 3. The operation control unit 18 moves the car 5 based on operations on the in-car operation panel 17 and a landing operation panel (not shown).

  The operation control unit 18 stops the operation of the elevator 1 when the safety circuit is interrupted. That is, the operation control unit 18 stops the movement of the cage 5 when at least one of the safety switches is activated. The operation control unit 18 restarts the operation of the elevator 1, for example, when all the safety switches return to the state before the operation.

  The notification control unit 19 controls the operations of the hall notification device 15 and the in-car notification device 16. For example, the notification control unit 19 displays characters and images on a liquid crystal display and an indicator. For example, the notification control unit 19 causes a speaker, an interphone, or the like to sound a buzzer sound and broadcast an audio announcement.

  The remote monitoring device 13 has a communication function. For example, the remote monitoring device 13 transmits information acquired from the control device 12 to an information center (not shown). The information center is provided in a building different from the building in which the control device 12 is provided, for example. The information center is, for example, a management server provided in a management company for the elevator 1.

  The switch state detection unit 20 detects that an internal safety switch is activated among safety switches or an external safety switch is activated among safety switches. The switch state detection unit 20 detects that the internal safety switch is activated or the external safety switch is activated based on, for example, the potential between successive contacts in the safety circuit. The switch state detection unit 20 transmits the detection result to the control device 12 via the communication path from the remote monitoring device 13.

  For example, when the operation mode of the elevator 1 is not the maintenance mode, the notification control unit 19 receives information indicating that the external safety switch has been activated when the switch state detection unit 20 detects that the external safety switch has been activated. The alarm 15 and the in-car alarm 16 are notified. The notification of the information is performed, for example, by sounding a buzzer sound, broadcasting an audio announcement, displaying an installed floor of the activated external safety switch, and displaying an illustration representing the activated external safety switch.

  For example, when the switch provided on the door of the firefighting equipment inspection port 9 is activated, the speaker or intercom in the basket 5 gives a voice announcement such as “The firefighting equipment inspection port is open. The elevator has been suspended.” To broadcast. In this case, the liquid crystal display or indicator in the basket 5 displays the floor number indicating the top floor where the firefighting equipment inspection port 9 is provided and an illustration showing the state in which the firefighting equipment inspection port 9 is open. The display of the floor number and the display of the illustration are alternately performed, for example, every 3 seconds.

  For example, when a switch provided at the door of the firefighting equipment inspection port 9 is activated, a speaker or an intercom at a hall on each floor emits a buzzer sound. In this case, the liquid crystal display or indicator at the landing on each floor displays an illustration showing the number of floors indicating the top floor where the firefighting equipment inspection port 9 is provided and the state where the firefighting equipment inspection port 9 is open. The display of the floor number and the display of the illustration are alternately performed, for example, every 3 seconds.

  FIG. 3 is a flowchart illustrating an operation example of the control device according to the first embodiment. The operation shown in this flowchart is started when the operation of the elevator 1 is stopped.

  The control device 12 determines whether or not the operation mode of the elevator 1 is the maintenance mode (step S101). When it is determined in step S101 that the operation mode of the elevator 1 is the maintenance mode, the control device 12 does not notify the information from the hall notification device 15 and the in-car notification device 16.

  When it determines with the operation mode of the elevator 1 not being a maintenance mode in step S101, the control apparatus 12 determines whether the switch of the fire-fighting equipment inspection port 9 act | operated (step S102). When it determines with the switch of the firefighting equipment inspection port 9 having act | operated by step S102, the control apparatus 12 alert | reports the information which shows that the switch of the firefighting equipment inspection port 9 has act | operated (step S103). When it determines with the switch of the firefighting equipment inspection port 9 not having act | operated by step S102, the control apparatus 12 does not perform the process of step S103.

  Following step S102 or step S103, the control device 12 determines whether or not the switch of the express zone rescue exit 10 has been actuated (step S104). When it determines with the switch of the express zone rescue exit 10 having been actuated by step S104, the control apparatus 12 alert | reports the information which shows that the switch of the express zone rescue exit 10 act | operated (step S105). When it determines with the switch of the express zone rescue exit 10 not operating in step S104, the control apparatus 12 does not perform the process of step S105.

  Following step S104 or step S105, the control device 12 determines whether or not the switch of the pit entrance 11 has been actuated (step S106). When it is determined in step S106 that the switch of the pit entrance 11 has been activated, the control device 12 notifies information indicating that the switch of the pit entrance 11 has been activated (step S107). When it is determined in step S106 that the switch of the pit entrance 11 is not activated, the control device 12 does not perform the process of step S107.

  In the first embodiment, the notification system includes a control device 12 and an external interface device 14. The external interface device 14 detects that an internal safety switch of the safety switches is activated or an external safety switch of the safety switches is activated. For example, when the operation mode of the elevator 1 is not the maintenance mode, the control device 12 detects that the external safety switch has been activated by the external interface device 14, and then sends an external signal from the hall alarm 15 provided at the hall of the elevator 1. Information indicating that the safety switch has been activated is notified. For this reason, according to Embodiment 1, when the external safety switch of the elevator 1 is actuated by an erroneous operation, it is possible to alert the person who has performed the erroneous operation. Thereby, for example, even if the inspection worker of the fire fighting equipment 7 accidentally opens the door of the fire fighting equipment inspection port 9 during the operation of the elevator 1, the operator can immediately notice the erroneous operation. As a result, it is possible to prevent the operation of the elevator 1 from being stopped for a long time due to the operation of the external safety switch due to an erroneous operation.

  In the first embodiment, the external interface device 14 is detachably attached to the contact of the safety switch and the control device 12. That is, the external interface device 14 can be installed without changing the connection of the conventional safety circuit. For this reason, it becomes possible to alert a person who has actuated the external safety switch of the elevator 1 by an erroneous operation by a simple configuration change.

  In the first embodiment, among the external safety switches of the elevator 1, those provided at the door of the pit entrance 11 are provided on the most downstream side in the current flow of the safety circuit. For example, when the operation mode of the elevator 1 is not the maintenance mode, the control device 12 detects that only the external safety switch provided on the most downstream side in the current flow is activated by the external interface device 14. Only the hall alarm 15 provided at the hall on the lowest floor where the elevator 1 can get on and off the car 5 may be operated. That is, when only the door of the pit doorway 11 is opened during the operation of the elevator 1, the control device 12 may notify only the hall alarm 15 on the lowest floor. In this case, it is possible to notify the necessary minimum range without waste. Further, in this case, even if the hall alarm 15 is not installed near the pit entrance 11, it is possible to alert the person who opened the door of the pit entrance 11.

  In the first embodiment, the external interface device 14 indicates that all the internal safety switches have not been activated and all the external safety switches have been in a pre-operation state after the external safety switch has been activated. When it is detected, information indicating the special operation may be notified from the in-car notification device 16, and the movement of the car 5 of the elevator 1 may be resumed when the special operation is performed on the in-car operation panel 17. That is, when the operation of the elevator 1 is stopped by the operation of the external safety switch, the operation of the elevator 1 may be resumed based on the judgment of the user who is on the cage 5. Thereby, for example, when the user determines that safety can be confirmed, the operation of the elevator 1 can be resumed without waiting for the maintenance worker to respond. The special operation is, for example, simultaneously pressing and holding the door open button and the door close button of the in-car operation panel 17.

  In the first embodiment, the remote monitoring device 13 may transmit information indicating that the operation of the elevator 1 has been stopped due to the operation of the external safety switch and information indicating that the operation of the elevator 1 has been resumed to the information center. . In this case, the management company of the elevator 1 can determine whether the inspection of the elevator 1 needs to be performed based on the information from the remote monitoring device 13. As a result, it is possible to prevent the maintenance worker from being dispatched even though the inspection of the elevator 1 is not actually required.

Embodiment 2. FIG.
Hereinafter, the configuration of the control device 12 and the notification system will be described focusing on the differences from the first embodiment. Parts that are the same as or equivalent to those in the first embodiment are given the same reference numerals, and a part of the description is omitted.

  FIG. 4 is a configuration diagram illustrating an example of a configuration of a notification system according to the second embodiment. The contacts indicated by letters in the figure are the contacts of the safety switch.

  As shown in FIG. 4, the notification system in the second embodiment does not include the remote monitoring device 13 and the external interface device 14. The control device 12 in the second embodiment has a communication function equivalent to that of the remote monitoring device 13 and a switch state detection unit 20.

  As shown in FIG. 4, the control device 12 is electrically connected to the safety circuit of the elevator 1. Contacts X and Y are contacts of the internal safety switch. Contacts A, B and C are contacts of the external safety switch. The contact A is, for example, a switch contact provided on the door of the firefighting equipment inspection port 9. The contact B is, for example, a switch contact provided on the door of the express zone rescue exit 10. The contact C is, for example, a switch contact provided on the door of the pit entrance 11.

  As shown in FIG. 4, the contacts X and A are connected to a power source. The contact Y is connected in series with the contact X. The contact A is connected in parallel with the contact X. The contact B is connected in series with the contact A. The contact C is connected in series with the contact B. The contacts Y and C are connected to the control device 12. That is, all the external safety switches are connected in series. Also, the external safety switch is not connected in series with the internal safety switch. As described above, the safety circuit according to the second embodiment is divided into two systems of the internal safety switch circuit and the external safety switch circuit.

  The switch state detection unit 20 detects that an internal safety switch of the safety switches is activated and an external safety switch of the safety switches is activated. The switch state detection unit 20 detects whether or not the contacts of all internal safety switches are closed. The switch state detection unit 20 detects whether or not the contacts of all external safety switches are closed. For example, when the contact A is in an open state, the switch state detection unit 20 detects that at least one of the contacts A, B, or C is in an open state.

  For example, when a switch provided on the door of the firefighting equipment inspection port 9 is activated, the speaker or intercom in the cage 5 is, for example, “The elevator was suspended because the external safety switch was activated. Check the zone rescue exits and pit entrances ”. In this case, the liquid crystal display or indicator in the basket 5 displays the floor number indicating the floor where the external safety switch is provided and an illustration showing the state where the external safety switch is activated. The display of the floor number and the display of the illustration are alternately performed, for example, every 3 seconds.

  For example, when a switch provided at the door of the firefighting equipment inspection port 9 is activated, a speaker or an intercom at a hall on each floor emits a buzzer sound. In this case, the liquid crystal display or indicator at the hall of each floor displays a floor number indicating the floor where the external safety switch is provided and an illustration showing the state where the external safety switch is open. The display of the floor number and the display of the illustration are alternately performed, for example, every 3 seconds.

  In the second embodiment, the control device 12 includes an operation control unit 18, a notification control unit 19, and a switch state detection unit 20. All the external safety switches of the elevator 1 are connected in series and are not connected in series with the internal safety switch. The switch state detection unit 20 detects whether or not the contacts of all external safety switches are closed. For this reason, according to Embodiment 2, the conducting wire connected to the control apparatus 12 can be reduced to two systems. As a result, it is possible to prevent the operation of the elevator 1 from pausing for a long time due to the operation of the external safety switch due to an erroneous operation while simplifying the wiring to the control device 12.

Embodiment 3 FIG.
Hereinafter, the configuration of the control device 12 and the notification system will be described focusing on the differences from the first and second embodiments. Parts that are the same as or correspond to those in the first or second embodiment are denoted by the same reference numerals, and a part of the description is omitted.

  FIG. 5 is a configuration diagram illustrating an example of a configuration of a notification system according to the third embodiment. The contacts indicated by letters in the figure are the contacts of the safety switch.

  As shown in FIG. 5, the notification system in the third embodiment does not include the remote monitoring device 13 and the external interface device 14 as in the second embodiment. The control device 12 in the second embodiment has a communication function equivalent to that of the remote monitoring device 13 and a switch state detection unit 20. The correspondence relationship between each contact in the safety circuit and the safety switch is the same as in the second embodiment.

  As shown in FIG. 5, the contacts X, A, B, and C are connected to a power source. The contact Y is connected in series with the contact X. The contact A is connected in parallel with the contacts X, B, and C. The contact B is connected in parallel with the contacts X, A, and C. The contact C is connected in parallel with the contacts X, A and B. That is, all external safety switches are connected in parallel. Also, the external safety switch is not connected in series with the internal safety switch. As described above, in the safety circuit according to the third embodiment, each contact of the external safety switch circuit is individually connected to the control device 12.

  The switch state detection unit 20 detects that an internal safety switch of the safety switches is activated and an external safety switch of the safety switches is activated. The switch state detection unit 20 detects whether or not the contacts of all internal safety switches are closed. The switch state detection unit 20 detects for each external safety switch whether or not the contact of the external safety switch is in a closed state.

  For example, when the switch provided on the door of the firefighting equipment inspection port 9 is activated, the speaker or intercom in the basket 5 gives a voice announcement such as “The firefighting equipment inspection port is open. The elevator has been suspended.” To broadcast. In this case, the liquid crystal display or indicator in the basket 5 displays the floor number indicating the top floor where the firefighting equipment inspection port 9 is provided and an illustration showing the state in which the firefighting equipment inspection port 9 is open. The display of the floor number and the display of the illustration are alternately performed, for example, every 3 seconds.

  For example, when a switch provided at the door of the firefighting equipment inspection port 9 is activated, a speaker or an intercom at a hall on each floor emits a buzzer sound. In this case, the liquid crystal display or indicator at the landing on each floor displays an illustration showing the number of floors indicating the top floor where the firefighting equipment inspection port 9 is provided and the state where the firefighting equipment inspection port 9 is open. The display of the floor number and the display of the illustration are alternately performed, for example, every 3 seconds.

  In the third embodiment, the control device 12 includes an operation control unit 18, a notification control unit 19, and a switch state detection unit 20, as in the second embodiment. All the external safety switches of the elevator 1 are connected in parallel and are not connected in series with the internal safety switch. The switch state detection unit 20 detects for each external safety switch whether or not the contact of the external safety switch is in a closed state. For this reason, according to Embodiment 3, it is specified reliably which external safety switch act | operated. As a result, the external safety switch can be returned to the state before the operation more quickly, and the time during which the operation of the elevator 1 is stopped due to the operation of the external safety switch due to an erroneous operation can be minimized.

  In Embodiment 3, for example, when the operation mode of the elevator 1 is not the maintenance mode, the notification control unit 19 is activated only by the switch state detection unit 20 provided in the door of the pit entrance 11 among the external safety switches. When this is detected, only the hall alarm 15 provided at the hall on the lowest floor where the elevator 1 can get on and off the car 5 may be operated. That is, when only the door of the pit doorway 11 is opened during operation of the elevator 1, the notification control unit 19 may notify only the lowest floor hall notification device 15. In this case, it is possible to notify the necessary minimum range without waste. Further, in this case, even if the hall alarm 15 is not installed near the pit entrance 11, it is possible to alert the person who opened the door of the pit entrance 11.

  In the second and third embodiments, the notification control unit 19 detects that the switch state detection unit 20 detects that all the external safety switches are in a state before the operation after the operation of the external safety switch. Information indicating a special operation may be notified from the notification device 16. The operation control unit 18 detects that the switch state detection unit 20 detects that all the internal safety switches are not activated and that all the external safety switches are in the pre-operation state after the external safety switch is activated. In addition, when the special operation is performed on the in-car operation panel 17, the movement of the car 5 of the elevator 1 may be resumed. That is, when the operation of the elevator 1 is stopped by the operation of the external safety switch, the operation of the elevator 1 may be resumed based on the judgment of the user who is on the car 5. Thereby, for example, when the user determines that safety can be confirmed, the operation of the elevator 1 can be resumed without waiting for the maintenance worker to respond. The special operation is, for example, simultaneously pressing and holding the door open button and the door close button of the in-car operation panel 17.

  In the second and third embodiments, the control device 12 may transmit information indicating that the operation of the elevator 1 has been stopped due to the operation of the external safety switch and information indicating that the operation of the elevator 1 has been resumed to the information center. Good. In this case, the management company of the elevator 1 can determine whether or not the inspection of the elevator 1 needs to be performed based on the information from the control device 12. As a result, it is possible to prevent the maintenance worker from being dispatched even though the inspection of the elevator 1 is not actually required.

  In the first, second and third embodiments, the notification control unit 19 displays information indicating the operation of the external safety switch at least of the hall notification device 15 and the in-car notification device 16 even when the operation mode of the elevator 1 is the maintenance mode. You may notify from one side. For example, when a specific operation is performed by the maintenance worker of the elevator 1 when switching to the maintenance mode or during the maintenance mode, the notification control unit 19 displays information indicating the operation of the external safety switch during the maintenance mode. The information may be available. In this case, for example, it is possible to notify the maintenance worker which external safety switch has been activated. In this case, for example, it is possible to widely inform the user that the maintenance worker is correctly performing maintenance inspection.

  FIG. 6 is a hardware configuration diagram of an elevator control device.

  Each function of the operation control unit 18, the notification control unit 19, and the switch state detection unit 20 in the control device 12 is realized by a processing circuit. The processing circuit may be dedicated hardware 50. The processing circuit may include a processor 51 and a memory 52.
