Description

The present disclosure relates to an elevator device.

In elevator systems, recovery operations are carried out after an earthquake causes the car to stop. If no abnormalities are detected during the recovery operation, the elevator system undergoes a temporary recovery. After that, a technician with specialized knowledge performs on-site inspection work, and the elevator system is fully restored.

Patent Document 1 also describes an elevator device. In the elevator device described in Patent Document 1, after an earthquake, the building owner or the like watches live video and determines whether or not there are any abnormalities. If the owner or the like confirms an abnormality in the live video, the restoration operation is stopped.

Japanese Patent Publication No. 2008-1494

In the past, in order to fully restore elevator equipment that was still in a temporary state, engineers had to go to the site and carry out the inspection work. This resulted in a heavy burden on engineers after an earthquake.

In the elevator system described in Patent Document 1, recovery operations will not start unless there is someone who can watch the live video. This causes problems such as delays in recovery of the elevator system after an earthquake.

This disclosure has been made to solve the problems described above. The purpose of this disclosure is to provide an elevator system that can reduce the burden on engineers after an earthquake and enable the elevator system to be restored quickly.

Embodiment 1.
Fig. 1 is a diagram showing an example of an elevator apparatus in a first embodiment. Fig. 2 is a diagram for explaining the function of the elevator apparatus shown in Fig. 1. The elevator apparatus includes a car 1 and a counterweight 2. The car 1 moves up and down in a hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended in the hoistway 3 by a rope 4.

The rope 4 is wound around a hoist 5. The hoist 5 drives the car 1. The control device 6 controls the hoist 5. That is, the movement of the car 1 is controlled by the control device 6. The control device 6 also controls the equipment provided in the car 1.

Figure 1 shows an example in which the hoisting machine 5 and the control device 6 are installed in a machine room 7 above the hoistway 3.

When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be installed at the top of the hoistway 3 or in a pit in the hoistway 3.

The monitoring device 8 is connected to the control device 6. The monitoring device 8 is a device that allows the elevator device to communicate with the outside. The monitoring device 8 communicates with external devices via a network 9. The external devices include a server 11. The server 11 is provided in a remote monitoring center 10 that monitors the elevator device.

A control cable 12 is connected between the car 1 and the control device 6. The control cable 12 is also connected between the car 1 and the monitoring device 8. The control cable 12 extends downward from the car 1. The control cable 12 extending downward from the car 1 changes direction inside the elevator shaft 3, extends upward, and is connected to the control device 6 and the monitoring device 8.

The cage 1 comprises a cage chamber 20, a door 21, a motor 22, a frame 23, a front beam 24, and an operation panel 25.

The cab 20 forms a space for passengers to ride in. The cab 20 is supported by a frame 23. The frame 23 surrounds the cab 20 from above, below, left and right. The frame 23 includes a lower member 23a. The lower member 23a is positioned horizontally below the cab 20 and across the cab 20. The front beam 24 is positioned below the cab 20.

The entrance to car 1 is opened and closed by door 21. Motor 22 drives door 21. Operation panel 25 includes an intercom 26 and a number of buttons. Operation panel 25 includes a destination button for registering a destination call, an open button for opening door 21, and a close button for closing door 21.

The cage 1 is provided with a display 30, a camera 31, a lamp 32, a camera 33, a microphone 34, and a vibration sensor 35.

The display 30 displays information to passengers in the car 1. The display 30 may be provided as part of the operation panel 25.

In the example shown in Figure 1, the camera 31 is fixed to the downward surface of the lower member 23a. That is, the camera 31 is provided outside the car 1. The camera 31 photographs the elevator shaft 3. In the example shown in Figure 1, the camera 31 photographs an image below the car 1. The image data acquired by the camera 31 is transmitted to the monitoring device 8 via the control cable 12.

The lamp 32 is fixed to the lateral surface of the front beam 24. A socket for a light bulb is provided in the car 1. The lamp 32 receives power from this socket.

As another example, power may be supplied from the light bulb socket to both the camera 31 and the lamp 32. Figure 1 shows an example in which an adapter 36 is fixed to a light bulb socket provided on the car 1. In the example shown in Figure 1, power is supplied to the camera 31 and the lamp 32 via the socket and the adapter 36.

The microphone 34 and the vibration sensor 35 are provided outside the car 1. In the example shown in FIG. 1, the microphone 34 and the vibration sensor 35 are arranged above the car room 20. The microphone 34 and the vibration sensor 35 may be provided as an integrated device. The voice data acquired by the microphone 34 is transmitted to the monitoring device 8 via the control cable 12. The vibration data acquired by the vibration sensor 35 is transmitted to the monitoring device 8 via the control cable 12.

The elevator device further includes a seismometer 13. The seismometer 13 is provided in the machine room 7. The seismometer 13 may also be provided in the elevator shaft 3. The seismometer 13 detects the acceleration of the building in which the elevator device is installed. The seismometer 13 outputs a signal corresponding to the detected acceleration. As an example, the seismometer 13 outputs a three-stage signal corresponding to the detected acceleration.

An operation panel 15 and a display 16 are provided at each landing 14 where the car 1 stops. Figure 1 shows an example in which the operation panel 15 has an up button and a down button. As another example, the operation panel 15 may have destination buttons. The display 16 displays information to passengers at the landing 14. The display 16 may be a liquid crystal display or an indicator light.

The control device 6 includes a memory unit 40, an operation control unit 41, an abnormality detection unit 42, and a display control unit 43. The monitoring device 8 includes an acquisition unit 51 and a communication unit 52.

The operation control unit 41 performs automatic operation, controlled operation, and recovery operation. Automatic operation is an operation for causing car 1 to respond sequentially to registered calls. Controlled operation is an operation for evacuating passengers in car 1 immediately after an earthquake occurs. Recovery operation is an operation for determining whether or not recovery is possible. Recovery operation is performed by actually moving car 1 after an earthquake occurs.

The operation of the elevator device will be described in detail below with reference to Figures 3 to 5. Figures 3 and 4 are flowcharts showing an example of the operation of the elevator device in embodiment 1. Figures 3 and 4 show a series of operations.

In the control device 6, the operation control unit 41 performs automatic operation (S101). If automatic operation is being performed, passengers can board the car 1 and go to their destination floor. While the operation control unit 41 is performing automatic operation, the control device 6 determines whether or not an earthquake has occurred (S102). If a specific signal is input from the seismometer 13 to the control device 6, the result of S102 is Yes.

If S102 is judged as Yes, the control device 6 judges whether or not the first start condition is satisfied (S103). The first start condition is a condition for starting controlled operation. As an example, if a signal indicating that acceleration equal to or above a certain level has been detected is input from the seismometer 13 to the control device 6 and the car 1 is moving, S103 is judged as Yes. If S103 is judged as Yes, the operation control unit 41 performs controlled operation (S104). In controlled operation, the car 1 stops at the landing 14 of the nearest floor. When the car 1 stops at the landing 14, the door 21 is opened.

Next, the control device 6 determines whether or not a second start condition is satisfied (S105). The second start condition is a condition for starting recovery operation. As an example, if a signal indicating that acceleration equal to or above a specific level has been detected is input from the seismometer 13 to the control device 6 and the stopped car 1 is unoccupied, the result of S105 is determined as Yes. If the result of S105 is Yes, the operation control unit 41 starts recovery operation (S106).

When recovery operation is being performed, recovery data is acquired by the control device 6 (S107). Also, when recovery operation is being performed, confirmation data is acquired by the acquisition unit 51 of the monitoring device 8 (S108).

The recovery data is data necessary for the control device 6 to automatically determine whether recovery is possible. The abnormality detection unit 42 detects an abnormality based on the recovery data acquired in S107. As an example, the recovery data includes the torque value of the hoist 5. The recovery data may also include voice data acquired by the intercom 26. The abnormality detection unit 42 detects an abnormality if the acquired torque value is not within a reference range. The abnormality detection unit 42 detects an abnormality if the maximum value of the acquired voice data exceeds a reference value. The reference range and reference value are stored in advance in the memory unit 40.

When an abnormality is detected by the abnormality detection unit 42 (Yes in S109), the operation control unit 41 stops the recovery operation (S110). When an abnormality is detected by the abnormality detection unit 42 (Yes in S109), the communication unit 52 of the monitoring device 8 issues a report to the monitoring center 10 (S110).

If no abnormality is detected by the abnormality detection unit 42 (No in S109), it is determined whether or not the recovery operation has ended (S111). If car 1, etc. performs all the specified operations and no abnormality is detected in all the acquired recovery data, it is determined as Yes in S111.

When the recovery operation ends without any abnormality being detected by the abnormality detection unit 42, the elevator device undergoes a temporary recovery (S112). During the temporary recovery, the operation control unit 41 operates the car 1 to respond sequentially to registered calls. Therefore, when the elevator device undergoes a temporary recovery, passengers can board the car 1 and go to their destination floors.

Furthermore, in the case of a temporary restoration, special control is performed that is not performed in normal operation. As the special control performed in S112, the display control unit 43 may display a specific display on the display 16 indicating that the restoration is temporary. For example, in S112, the display control unit 43 causes an indicator light provided at the hall 14 to flash. The display control unit 43 may also display a specific display on the display 30 indicating that the restoration is temporary. By seeing this display, passengers can know that the restoration is not complete.

When the recovery operation is completed without any abnormality being detected by the abnormality detection unit 42, the communication unit 52 transmits the confirmation data acquired by the acquisition unit 51 to the server 11 of the monitoring center 10 (S113). The confirmation data is used by a technician with specialized knowledge at the monitoring center 10 to determine whether or not it is acceptable to fully recover the elevator device.

The confirmation data includes image data acquired by camera 31. The confirmation data may further include image data acquired by camera 33. The confirmation data also includes audio data acquired by microphone 34 and vibration data acquired by vibration sensor 35.

Because the confirmation data includes image data acquired by the camera 31, the image data does not need to be included in the recovery data. Because the confirmation data includes audio data acquired by the microphone 34, the audio data does not need to be included in the recovery data. If the recovery data includes audio data acquired by the intercom 26, the audio data does not need to be included in the confirmation data.

Figure 5 is a flowchart showing an example of the operation of the server 11. The server 11 determines whether or not confirmation data has been received (S201). When the server 11 receives the confirmation data transmitted from the monitoring device 8 in S113, the determination in S201 is Yes.

If S201 returns Yes, the server 11 displays the confirmation data on the display 17 (S202). For example, the server 11 converts the image data acquired by the camera 31 into a panoramic image and displays it on the display 17. This allows an engineer to check the entire elevator shaft 3 at the monitoring center 10. As another example, the server 11 performs frequency analysis on the audio data acquired by the microphone 34 and the vibration data acquired by the vibration sensor 35. The server 11 may display the results of the frequency analysis on the display 17.

In S202, it is desirable to provide a display that enables the engineer to confirm the following items.
- Whether the governor rope has become caught - Whether the elevator equipment is damaged, and whether the exterior wall of the elevator is damaged - Whether the equipment inside the car is damaged - Whether the door device at the landing is damaged Furthermore, it is desirable that the confirmation data include data that is not included in the recovery data so that events that cannot be detected by the abnormality detection unit 42 can be read from the display 17.

When the confirmation data is displayed in S202, the server 11 determines whether recovery is permitted (S203). If the technician checks the confirmation data and determines that it is OK to fully restore the elevator device, he or she performs a specific operation. For example, when a specific button displayed on the display 17 is clicked, the result of S203 is determined to be Yes. If the result of S203 is determined to be Yes, the server 11 sends a recovery signal to the elevator device that sent the confirmation data in S201 (S204).

In the control device 6, when confirmation data is transmitted from the communication unit 52 of the monitoring device 8 in S113, it is determined whether or not a recovery signal has been received from the server 11 in response thereto (S114). When the communication unit 52 receives the recovery signal transmitted from the server 11 in S204, the determination in S114 is Yes.

If S114 is judged as Yes, the elevator device undergoes a permanent recovery (S115). That is, if S114 is judged as Yes, the operation control unit 41 resumes normal operation. Also, if S114 is judged as Yes, the special control started in S112 ends. If a specific display indicating a temporary recovery is being performed on the display 16, the display control unit 43 erases the specific display from the display 16. If a specific display indicating a temporary recovery is being performed on the display 30, the display control unit 43 erases the specific display from the display 30.

In the example shown in this embodiment, recovery operation is automatically initiated after an earthquake. Furthermore, if recovery operation is completed without detecting any abnormalities, the elevator equipment undergoes a temporary recovery. This allows the elevator equipment to be restored (temporary recovery) early. Furthermore, in the example shown in this embodiment, there is no need for an engineer to go to the site and perform confirmation work in order to fully restore the elevator equipment. This reduces the burden on engineers after an earthquake.

The confirmation data that the engineer checks to fully restore the elevator equipment is acquired while recovery operations are being performed. During recovery operations, for example, the car 1 stops at each landing 14, and the doors 21 are opened and closed at each landing 14. This allows the engineer to check events at the monitoring center 10 that cannot be detected as abnormalities from the recovery data, such as whether or not there is any damage to the door equipment at the landing 14 and whether or not there is any damage to the exterior walls.
