Embodiment 1.
FIG. 1 is a diagram showing an example of an elevator device according to the first embodiment. The elevator device includes, for example, a basket 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The balance weight 2 moves up and down on the hoistway 3. The basket 1 and the counterweight 2 are suspended from the hoistway 3 by the main rope 4.

The main rope 4 is wound around the drive sheave 6 of the hoisting machine 5. The hoisting machine 5 is controlled by the control device 7. For example, the control device 7 controls the rotation and stop of the drive sheave 6. The car 1 moves according to the rotation of the drive sheave 6. The car 1 stops at the height of the landing 8, for example. The monitoring device 9 is connected to the control device 7. The monitoring device 9 communicates with, for example, an external monitoring center.

The speed governor 10 operates the emergency stop 11 when the descending speed of the car 1 exceeds the reference speed. The emergency stop 11 is provided in the car 1. When the emergency stop 11 operates, the car 1 is forcibly stopped. The governor 10 includes, for example, a speed governor 12, a speed governor 13, and a tension wheel 14. The governor rope 12 is connected to the car 1. The governor rope 12 is wound around the governor sheave 13 and the tension wheel 14. When the car 1 moves, the speed governor rope 12 moves. When the speed governor rope 12 moves, the speed control sheave 13 and the tension wheel 14 rotate. The governor 10 outputs a rotation signal of the speed governor sheave 13. The rotation signal output from the governor 10 is input to the control device 7.

The car 1 includes, for example, a door 15, a door switch 16, a handrail device 17, and a handrail switch 18. The door 15 opens and closes the doorway formed in the car 1. When the car 1 is stopped at the landing 8, the door 15 faces the door 19 provided at the landing 8. The door switch 16 detects that the door 15 is arranged in the fully closed position. If the door 15 is arranged in the fully closed position, the doorway formed in the car 1 is closed. When the door switch 16 detects that the door 15 is arranged in the fully closed position, the door switch 16 outputs a fully closed signal. The fully closed signal output from the door switch 16 is input to the control device 7.

The handrail device 17 is provided on the car chamber so as to be foldable. The handrail device 17 is basically stored on the cab in a folded state. Elevator maintenance personnel may perform maintenance work on the car 1. The maintenance staff assembles the handrail device 17 when performing maintenance work on the car 1. The maintenance staff performs maintenance work in a space surrounded by the handrail device 17. The handrail switch 18 detects that the handrail device 17 has been assembled. When the handrail switch 18 detects that the handrail device 17 has been assembled, the handrail switch 18 outputs an assembly signal. The assembly signal output from the handrail switch 18 is input to the control device 7.

FIG. 2 is a diagram showing a main part of the elevator device shown in FIG. FIG. 2 shows a specific example of the elevator landing 8 and the monitoring device 9.

The door 19 opens and closes the doorway formed in the landing 8. The entrance / exit of the landing 8 is formed by the landing three-sided frame 20. A landing operation panel 21 is provided on one of the vertical pillars 20a of the landing three-sided frame 20. The landing operation panel 21 includes, for example, a landing button 22. When the landing button 22 is pressed, the landing operation panel 21 outputs a landing call signal indicating that the landing button 22 has been pressed. The landing call signal output from the landing operation panel 21 is input to the control device 7.

FIG. 2 shows an example in which the inspection tag 23 is provided at the landing 8. The inspection tag 23 is fixed to, for example, the upper frame 20b of the landing three-sided frame 20 by a magnet. The inspection tag 23 is removable from the landing 8. The inspection tag 23 indicates that the elevator is currently being inspected. The inspection tag 23 is attached to the landing 8 by the maintenance staff when the maintenance staff of the elevator performs maintenance work. The user can know that the elevator is currently being inspected and cannot be used because the inspection tag 23 is attached to the landing 8.

The check tag 23 includes, for example, a call button 24 and a transmission unit 25. The call button 24 is a button for calling a maintenance worker who is performing maintenance work by a person at the landing 8. When the call button 24 is pressed, the transmission unit 25 transmits a call signal to the monitoring device 9. FIG. 2 shows an example in which the transmission unit 25 wirelessly transmits a call signal to the monitoring device 9.

The check tag 23 may be connected to the monitoring device 9 by wire. FIG. 3 is a diagram showing another mounting example of the inspection tag 23. In the example shown in FIG. 3, when the inspection tag 23 is fixed at a specific position on the upper frame 20b, the inspection tag 23 is wiredly connected to the landing operation panel 21. The call signal from the transmission unit 25 is input to the monitoring device 9 via the landing operation panel 21 and the control device 7.

FIG. 4 is a diagram showing another mounting example of the inspection tag 23. In the example shown in FIG. 4, similarly to the example shown in FIG. 3, when the inspection tag 23 is fixed at a specific position of the upper frame 20b, the inspection tag 23 is wiredly connected to the landing operation panel 21. FIG. 4 shows an example in which a support device for supporting the inspection tag 23 is provided on the upper frame 20b of the landing 8. The support device includes, for example, a micro switch 26 and a support piece 27.

For example, the micro switch 26 is arranged so that the actuator projects from the lower surface of the upper frame 20b. When the actuator of the micro switch 26 is pushed from below and the internal contact is closed, the support piece 27 rotates in the A direction in FIG. Reference numeral 27a in FIG. 4 indicates the arrangement of the support piece 27 when the actuator of the micro switch 26 is not pressed. The elevator maintenance staff pushes the actuator of the micro switch 26 from below by the upper part of the inspection tag 23 when performing the maintenance work. As a result, the upper part of the inspection tag 23 is supported from both sides by the support piece 27 as shown in FIG. In the state shown in FIG. 4, the signal line from the inspection tag 23 is connected to the connector 28 provided on the upper frame 20b.

As shown in FIG. 2, the monitoring device 9 includes, for example, a receiving unit 30, a car upper determination unit 31, a traveling determination unit 32, a position determination unit 33, and a calling unit 36.

The receiving unit 30 receives a calling signal transmitted by pressing the calling button 24 of the inspection tag 23.

The car upper determination unit 31 determines whether or not there is a person on the car 1. Any method may be used to determine that there is a person on the basket 1. For example, an elevator maintenance worker assembles a handrail device 17 when performing maintenance work on a car 1. The car upper determination unit 31 may determine that a person is on the car 1 by outputting an assembly signal from the handrail switch 18. The car upper determination unit 31 may determine that there is a person on the car 1 based on a signal from another button operated by the maintenance person on the car 1.

The travel determination unit 32 determines whether or not the car 1 is traveling. Any method may be used as a method for determining that the car 1 is traveling. For example, the travel determination unit 32 determines whether or not the car 1 is traveling based on the rotation signal output from the governor 10. When the hoisting machine 5 outputs the rotation signal of the drive sheave 6, the traveling determination unit 32 may determine whether or not the car 1 is traveling based on the rotation signal from the hoisting machine 5.

The position determination unit 33 determines whether or not the position of the car 1 is included in the passing range. In the present embodiment, the car 1 moves up and down in the hoistway 3. Therefore, the position of the car 1 is synonymous with the height of the car 1. The position of the car 1 can be detected, for example, based on the rotation signal output from the governor 10. The control device 7 may have a function of detecting the position of the car 1.

The passing range is a specific range including a position where the car 1 is at the same height as the balanced weight 2. The passing range is registered in advance in the monitoring device 9 or the control device 7.

The calling unit 36 calls the mobile terminal 40 owned by the elevator maintenance staff. The information for calling the mobile terminal 40 is registered in advance in the monitoring device 9 or the control device 7.

Hereinafter, specific functions of the elevator device will be described with reference to FIG. FIG. 5 is a flowchart showing an operation example of the monitoring device 9.

The elevator maintenance staff attaches the inspection tag 23 to the landing 8 when performing maintenance work. The user can know that the elevator is currently being inspected and cannot be used because the inspection tag 23 is attached to the landing 8.

The monitoring device 9 determines whether or not the receiving unit 30 has received the call signal from the inspection tag 23 (S101). For example, a user using a wheelchair or a caregiver thereof presses the call button 24 of the inspection tag 23 when he / she wants to use the elevator when the inspection tag 23 is attached to the landing 8. As a result, the calling signal is transmitted from the transmission unit 25. The call signal is received by the receiving unit 30 of the monitoring device 9 (Yes in S101).

When the receiving unit 30 receives the call signal, the car upper determination unit 31 determines whether or not there is a person on the car 1 (S102). For example, the car top determination unit 31 determines that there is no person on the car 1 unless the assembly signal is output from the handrail switch 18 (No in S102). When the car upper determination unit 31 determines that there is no person on the car 1, the calling unit 36 calls the mobile terminal 40 (S105). When the mobile terminal 40 receives a call from the calling unit 36, it sounds, for example, a ringing sound. As a result, the maintenance staff who owns the mobile terminal 40 can know that there is a person who wants to use the elevator during the maintenance work.

When the car upper determination unit 31 determines in S102 that a person is on the car 1, the traveling determination unit 32 determines whether or not the car 1 is traveling (S103). For example, the traveling determination unit 32 determines that the car 1 is stopped if the speed governor sheave 13 is not rotating (No in S103). When the traveling determination unit 32 determines that the car 1 is stopped, the calling unit 36 calls the mobile terminal 40 (S105).

When the traveling determination unit 32 determines in S103 that the car 1 is traveling, the position determination unit 33 determines whether or not the position of the car 1 is included in the passing range (S104). When the position determination unit 33 determines that the position of the car 1 is not included in the passing range (No in S104), the calling unit 36 calls the mobile terminal 40 (S105). On the other hand, when the position determination unit 33 determines that the position of the car 1 is included in the passing range (Yes in S104), the calling unit 36 determines that the position of the car 1 is not included in the passing range. The mobile terminal 40 is not called until the determination is made. After that, when the position determination unit 33 determines that the position of the car 1 is not included in the passing range, the calling unit 36 calls the mobile terminal 40 (S105).

In the example shown in this embodiment, the user can call a maintenance worker who is performing maintenance work from the landing 8. In addition, the call can be suppressed under specific conditions. That is, when there is a person on the car 1 and the car 1 is running, when the call button 24 is pressed, it is determined whether or not the position of the car 1 is included in the passing range. Then, if the position of the car 1 is not included in the passing range, the maintenance staff is called immediately. On the other hand, if the position of the car 1 is included in the passing range, the maintenance staff is not called immediately. In the example shown in FIG. 5, the maintenance personnel are called on the condition that the position of the car 1 is no longer included in the passing range.

The present embodiment shows the following examples. That is, if the first determination condition is satisfied when the call button 24 is pressed, the position determination unit 33 makes a determination. Then, when the position of the car 1 is included in the passing range, the calling unit 36 calls the mobile terminal 40 after the second determination condition is satisfied.

FIG. 5 is established when the first determination condition is determined by the car upper determination unit 31 determining that a person is on the car 1 and the traveling determination unit 32 determining that the car 1 is running. An example is shown. The second determination condition is a condition for considering that the position of the car 1 is out of the passing range. FIG. 5 shows an example in which the second determination condition is satisfied when the position determination unit 33 determines that the position of the car 1 is not included in the passing range. Hereinafter, other examples in which this elevator device can be adopted will be described.

FIG. 6 is a flowchart showing another operation example of the monitoring device 9. FIG. 6 shows an example in which the second determination condition is different from the example shown in FIG. The processes shown in S201 to S203 of FIG. 6 are the same as the processes shown in S101 to S103 of FIG.

When the traveling determination unit 32 determines in S203 that the car 1 is traveling, the position determination unit 33 determines whether or not the position of the car 1 is included in the passing range (S204). When the position determination unit 33 determines that the position of the car 1 is not included in the passing range (No in S204), the calling unit 36 calls the mobile terminal 40 (S206). On the other hand, when the position determination unit 33 determines that the position of the car 1 is included in the passing range (Yes in S204), the calling unit 36 determines whether or not a certain time has elapsed since the determination in S204 was performed. (S205). The calling unit 36 does not call the mobile terminal 40 until it is determined by S205 that a certain time has elapsed. After that, when it is determined by S205 that a certain time has elapsed, the calling unit 36 calls the mobile terminal 40 (S206).

In the example shown in FIG. 6, the second determination condition is satisfied when a certain time elapses after the position determination unit 33 determines that the position of the car 1 is included in the passing range. That is, the calling unit 36 considers that the position of the car 1 is out of the passing range after the lapse of the above-mentioned fixed time, and calls the mobile terminal 40.

FIG. 7 is a flowchart showing another operation example of the monitoring device 9. FIG. 7 shows an example in which the first determination condition is different from the example shown in FIG.

In the example shown in FIG. 7, the monitoring device 9 further includes a door determination unit 34. The door determination unit 34 determines whether or not the door 15 of the car 1 is closed. Any method may be used for determining whether or not the door 15 of the car 1 is closed. For example, the door determination unit 34 may determine that the door 15 is closed by outputting a fully closed signal from the door switch 16. The door determination unit 34 may determine whether or not the door 15 is closed based on a signal from another sensor provided in the car 1 or the like.

The process shown in S301 of FIG. 7 is the same as the process shown in S101 of FIG. When the receiving unit 30 receives the call signal, the door determination unit 34 determines whether or not the door 15 of the car 1 is closed (S302). For example, the door determination unit 34 determines that the door 15 is not closed unless a fully closed signal is output from the door switch 16 (No in S302). When the door determination unit 34 determines that the door 15 is not closed, the calling unit 36 does not make a call (S307).

When the door determination unit 34 determines in S302 that the door 15 is closed, the car upper determination unit 31 determines whether or not there is a person on the car 1 (S303). The process shown in S303 to S306 of FIG. 7 is the same as the process shown in S102 to S105 of FIG.

In the example shown in FIG. 7, the first determination condition is satisfied by the door determination unit 34 determining that the door 15 of the car 1 is closed, in addition to the condition shown in FIG. In the example shown in FIG. 7, the second determination condition may be the same as the example shown in FIG.

FIG. 8 is a flowchart showing another operation example of the monitoring device 9. FIG. 8 shows an example in which the first determination condition is different from the example shown in FIG.

In the example shown in FIG. 8, the monitoring device 9 further includes a mode determination unit 35. The mode determination unit 35 determines whether or not the operation mode of the elevator is the manual mode. The operation mode includes an automatic mode and a manual mode. The automatic mode is an operation mode in which the car 1 is automatically answered to the registered call. The manual mode is an operation mode in which a maintenance person or the like manually moves the car 1 with a dedicated device. The mode determination unit 35 determines whether or not the operation mode is the manual mode, for example, based on a specific signal input from the control device 7.

The process shown in S401 of FIG. 8 is the same as the process shown in S101 of FIG. When the receiving unit 30 receives the call signal, the mode determination unit 35 determines whether or not the operation mode is the manual mode (S402). When the mode determination unit 35 determines that the operation mode is not the manual mode, the calling unit 36 calls the mobile terminal 40 (S406).

When the mode determination unit 35 determines in S402 that the operation mode is the manual mode, the travel determination unit 32 determines whether or not the car 1 is traveling (S403). The process shown in S403 to S406 of FIG. 8 is substantially the same as the process shown in S102 to S105 of FIG.

In the example shown in FIG. 8, the first determination condition is satisfied by the mode determination unit 35 determining that the operation mode is the manual mode in addition to the condition shown in FIG. In the example shown in FIG. 8, the second determination condition may be the same as the example shown in FIG.

In the example shown in this embodiment, the user can directly call the maintenance staff of the elevator. Therefore, the user does not need to contact a remote monitoring center or the like. However, for example, if it is determined as Yes in S104 of FIG. 5, the call is not performed until it is subsequently determined as No in S104. In such a case, since there is no reaction after pressing the call button 24, the user may contact a remote monitoring center or the like even though the call is made immediately after that.

In order to prevent such a situation, the inspection tag 23 may be further provided with a speaker. In such a case, the monitoring device 9 further includes a notification control unit 37. The notification control unit 37 controls, for example, the speaker provided on the inspection tag 23. When the call button 24 is pressed, the notification control unit 37 makes a call when the position determination unit 33 determines that the first determination condition is satisfied and the position of the car 1 is included in the passing range. A voice guidance to that effect is output from the speaker. For example, when the notification control unit 37 determines Yes in S104, the notification control unit 37 outputs a voice guidance to the effect that the call is being made from the speaker.

The notification control unit 37 may control a notification device (not shown) provided in the landing 8. The alarm is, for example, a display or a speaker. In such a case, when the call button 24 is pressed, the notification control unit 37 calls when the position determination unit 33 determines that the first determination condition is satisfied and the position of the car 1 is included in the passing range. The above-mentioned alarm informs the user that the notification is being performed.

In the present embodiment, an example in which the call button 24 is provided on the inspection tag 23 has been described.
This is just an example. The call button 24 may be provided on, for example, the landing operation panel 21.

In the present embodiment, an example in which the monitoring device 9 only calls the mobile terminal 40 has been described. This is just an example. The inspection tag 23 or the landing 8 may be provided with an intercom function. That is, the inspection tag 23 or the landing 8 may be provided with a microphone and a speaker. In such a case, the maintenance staff and the user can have a direct conversation after the maintenance staff is called.
