A detailed description is given below with reference to the drawings. Duplicate descriptions are appropriately simplified or omitted. In each figure, the same reference numerals denote the same or corresponding parts.

Embodiment 1.
FIG. 1 is a diagram showing an example of a system including an elevator device 1 according to Embodiment 1. FIG. The elevator system 1 is connected via a network 2 to a remote information center 4 with an operator. As an example, network 2 is an IP network. An IP network is a communication network using IP (Internet Protocol) as a communication protocol. Network 2 may be a closed network or an open network. Information center 4 manages a large number of elevator devices. The elevator device 1 is an example of an elevator device managed by the information center 4 .

The elevator device 1 includes a car 5 and a counterweight 6. The car 5 moves up and down the hoistway 7 . The car 5 and counterweight 6 are suspended in the hoistway 7 by ropes 8 . The counterweight 6 moves up and down the hoistway 7 in a direction opposite to the direction in which the car 5 moves. FIG. 1 shows an example of a 1:1 roping elevator system.

The hoist 9 drives the car 5. The hoisting machine 9 comprises a sheave 10 , a motor 11 , an encoder 12 (not shown in FIG. 1), and a braking device 13 .

The sheave 10 is rotatably supported by the frame of the hoisting machine 9. A rope 8 is wound around the sheave 10 . The motor 11 generates driving force for driving the sheave 10 . That is, the motor 11 rotates the sheave 10 . The encoder 12 outputs a signal corresponding to the rotation angle of the sheave 10 .

The brake device 13 is a device for holding the car 5 stationary. The braking device 13 prevents rotation of the sheave 10 during operation. If the braking device 13 is not operating, the sheave 10 can rotate. In the following, the expression "operating" with respect to the braking device 13 is used to indicate the state in which the braking device 13 is exerting its function, that is, the state in which the sheave 10 is prevented from rotating. The expression "non-operating" with respect to the braking device 13 is used to describe the state in which the braking device 13 is not performing its function, i.e., it is not preventing the sheave 10 from rotating.

As an example, the braking device 13 includes a rotating body and a shoe. The rotating body rotates in conjunction with the sheave 10 . The shoe is movably provided so as to contact and separate from the rotating body. A resistance to the rotation of the sheave 10 is generated by pressing the shoe against the rotating body. In such a braking device 13, when electric power is supplied to the braking device 13, the shoe is separated from the rotating body, and the braking device 13 is deactivated. That is, the braking device 13 is released. When the electric power to the braking device 13 is cut off, the shoe is pressed against the rotating body and the braking device 13 operates.

The control device 14 controls the hoist 9 . That is, movement of the car 5 is controlled by the control device 14 . A monitoring device 15 is connected to the control device 14 . Monitoring device 15 communicates with information center 4 via network 2 .

FIG. 1 shows an example in which the hoisting machine 9 and the control device 14 are provided in the machine room 16 above the hoistway 7 . The hoisting machine 9 and the control device 14 may be provided in the hoistway 7 . The hoisting machine 9 may be provided at the top of the hoistway 7 or may be provided in the pit of the hoistway 7 .

The car 5 and the control device 14 are connected by a control cable 17. Equipment provided in the car 5 is controlled by the control device 14 . The car 5 has a door 21 , a motor 22 , a weighing device 23 , a wireless communication device 24 and an operation panel 25 .

The doorway of the car 5 is opened and closed by the door 21. Motor 22 generates driving force for driving door 21 . A weighing device 23 measures the loaded load of the car 5 . FIG. 1 shows an example in which the weighing device 23 is provided below the car 5 . A weighing device 23 may be provided at the end of the rope 8 .

The wireless communication device 24 is a device for performing wireless communication with other devices present in the car 5. For example, the wireless communication device 24 wirelessly communicates with the mobile terminal 18 owned by the passenger according to a specific communication standard such as Bluetooth (registered trademark). As an example, the mobile terminal 18 is a smart phone. FIG. 1 shows an example in which the wireless communication device 24 is built into the operation panel 25. As shown in FIG.

The operation panel 25 includes a display 26 and buttons 27. The indicator 26 is an example of an annunciator for providing information to passengers in the car 5 . The operation panel 25 may be provided with a speaker as an alarm. The operation panel 25 may be provided with both the indicator 26 and the speaker as alarm devices. Buttons 27 include a destination button, a door open button, and a door close button. Other buttons may be included in button 27 .

The elevator device 1 includes a landing device for detecting that the car 5 is placed in a specific landing zone. The landing zone is preset according to the height of each landing 31 . For example, the landing zone set according to the height of the landing 31 on the Nth floor includes the position where the car 5 stops at the landing 31 on the Nth floor. The position where the car 5 stops at the landing 31 of the Nth floor is the position of the car 5 at which the height of the floor of the landing 31 of the Nth floor and the floor of the car 5 are the same.

As an example, the landing device includes a photoelectric sensor 32 and a plate 33. A photoelectric sensor 32 is provided on the car 5 . A plate 33 is provided in the hoistway 7 . The plate 33 is arranged according to the height of each landing 31 . The range in which the photoelectric sensor 32 can detect the plate 33 arranged according to the height of the landing 31 on the N floor is the landing zone on the N floor. When the photoelectric sensor 32 detects the plate 33 , a detection signal corresponding to the detected plate 33 is transmitted from the photoelectric sensor 32 to the control device 14 .

FIG. 2 is a diagram for explaining the functions of the control device 14 and the monitoring device 15. FIG. As shown in FIG. 2, the control device 14 includes a confinement detection unit 41, an operation control unit 42, a condition determination unit 43, a communication control unit 44, a notification control unit 45, a brake control unit 46, a position detection unit 47, and a door control unit. 48 , a passenger detection unit 49 , a prohibition unit 50 and a passenger detection unit 51 . The monitoring device 15 has a communication unit 52 .

The operation of this system will be described in detail below with reference to FIGS. 3 to 5 as well. 3 and 4 are flow charts showing an operation example of the control device 14 and the monitoring device 15. FIG. 3 and 4 show a sequence of operations.

The control device 14 determines whether or not a passenger is trapped in the car 5 (S101). The confinement detector 41 detects that the passenger is confined in the car 5 . The confinement detection unit 41 may detect the confinement of the passenger using the load measured by the weighing device 23 . If the car 5 is equipped with a camera, the confinement detection unit 41 may detect the confinement of the passenger using an image captured by the camera.

When the confinement detection unit 41 detects confinement, S101 is determined as Yes. If it is determined as Yes in S101, the communication section 52 transmits a lock-in signal to the server provided in the information center 4 (S102). The server is an example of an external device. The communication unit 52 transmits a confinement signal to a specific external device in S102.

At the information center 4 that receives the confinement signal, the operator determines whether or not the elevator device 1 can perform an automatic rescue operation. When the operator confirms that there is no problem even if the automatic rescue operation is performed, the server transmits a permission signal S1 to the elevator device 1 as a response to the confinement signal. If the operator determines that there is a problem with performing the automatic rescue operation, the server transmits a disapproval signal S2 to the elevator device 1 as a response to the confinement signal.

When the confinement signal is transmitted in S102, the control device 14 determines whether or not the non-permission signal S2 has been received from the server (S103). If it is determined No in S103, the control device 14 determines whether or not the permission signal S1 is received from the server (S104).

When the communication unit 52 receives the permission signal S1 from the server as a response to the confinement signal transmitted in S102, it is determined as Yes in S104. If determined as Yes in S104, the operation control unit 42 starts the automatic rescue operation (S105). Automatic rescue operation is operation for rescuing passengers trapped in the car 5 . When the automatic rescue operation is started, the operation control unit 42 automatically performs specific operations necessary to rescue the passenger.

On the other hand, when the communication unit 52 receives the non-permission signal S2 from the server as a response to the confinement signal transmitted in S102, it is determined as Yes in S103. If determined as Yes in S103, the operation control unit 42 does not start the automatic rescue operation. That is, if it is determined as Yes in S103, the automatic rescue operation is not performed. If it is determined as Yes in S103, the condition determination unit 43 determines whether or not a specific start condition is satisfied (S106). The start condition is a condition for starting a rescue operation using the passenger's mobile terminal 18 . The start condition is set in advance.

As an example, if the anomaly that caused the confinement was a specific anomaly, the start condition would not be met. The specified anomalies may include a brake slip anomaly. If the sheave 10 is rotating while the braking device 13 is operating, a brake slip abnormality is detected. Rotation of sheave 10 is detected based on a signal from encoder 12 . The specified anomalies may include traction anomalies. If the position of the car 5 changes while the sheave 10 is not rotating, a traction anomaly is detected. The specified anomalies may include other anomalies such as safety circuit operation anomalies and inverter anomalies. In the example shown in FIG. 3, the start condition includes that the communication unit 52 receives the disallow signal S2 from the server in response to the lock-in signal. That is, in the example shown in FIG. 3, the start condition is not satisfied unless the communication unit 52 receives the disapproval signal S2 from the server.

When the start condition is met, S106 is determined as Yes. When it is determined as Yes in S106, the communication control unit 44 outputs radio waves for communicating with the mobile terminal 18 from the wireless communication device 24 (S107). Further, when it is determined as Yes in S106, the notification control unit 45 displays information necessary for the portable terminal 18 to communicate with the wireless communication device 24 on the display 26 (S108). Passengers confined in the car 5 can connect the mobile terminal 18 to the wireless communication device 24 by operating their own mobile terminal 18 while viewing the contents displayed on the display 26 .

FIG. 5 is a flowchart showing an operation example of the mobile terminal 18. FIG. An application for an elevator is preferably pre-installed in the mobile terminal 18 . In the following description, this application will be referred to as "application A". As an example, when the mobile terminal 18 receives the radio waves output from the wireless communication device 24 in S107, the application A is automatically activated. When the application A is activated, the portable terminal 18 determines whether or not it is connected to the wireless communication device 24 (S201).

The passenger can obtain information for connecting the mobile terminal 18 to the wireless communication device 24 by viewing the content displayed on the display device 26 in S108. As an example, a password for connecting to the wireless communication device 24 is displayed on the display 26 . As another example, the display 26 may display a two-dimensional barcode for connecting to the wireless communication device 24 . Passengers can connect the mobile terminal 18 to the wireless communication device 24 by inputting the password displayed on the display 26 or photographing the two-dimensional bar code. When the mobile terminal 18 is connected to the wireless communication device 24, it is determined as Yes in S201.

If it is determined as Yes in S201, the portable terminal 18 determines whether or not the send button for transmitting the operation command has been pressed (S202). As an example, in application A, when the mobile terminal 18 is connected to the wireless communication device 24 , the send button is displayed on the display of the mobile terminal 18 .

The following information may be displayed on the display 26 of the car 5 in S108.
・Stay away from the door when pressing the send button.
- By continuing to press the send button, the car moves toward a nearby floor.
- The car stops by releasing the send button.
・After the door opens, check the outside and get out of the car.

By seeing the content displayed on the display 26, the passengers in the car 5 understand that the car 5 will move by pressing the send button. When the passenger presses the send button on his mobile terminal 18 (Yes in S202), the mobile terminal 18 transmits an operation command to the wireless communication device 24 (S203).

As shown in FIG. 4, in the control device 14, when it is determined as Yes in S106, it is determined whether or not an operation command has been received from the mobile terminal 18 (S109). When the wireless communication device 24 receives an operation command from the mobile terminal 18 communicating with the wireless communication device 24, the determination in S109 is Yes. If it is determined as Yes in S109, the control device 14 starts a rescue process for rescuing the passenger in response to a command from the passenger trapped in the car 5. FIG.

In the rescue process, first, the brake control unit 46 deactivates the brake device 13 (S110). Thus, if the car 5 is lighter than the counterweight 6, the car 5 will move upward. If the car 5 is heavier than the counterweight 6, the car 5 will move downwards. For example, the brake control unit 46 repeatedly deactivates the brake device 13 for a certain period of time in the rescue process. The certain period of time is, for example, 0.5 seconds. After deactivating the brake device 13 for 0.5 seconds, the brake control unit 46 activates the brake device 13 (S111). This causes the car 5 to stop.

Also, if it is determined as Yes in S109, the control device 14 determines whether or not a stop command has been received from the mobile terminal 18 (S112).

As shown in FIG. 5, when the mobile terminal 18 transmits the operation command to the wireless communication device 24 in S203, it is determined whether or not the transmission button is pressed (S204). If the passenger keeps pressing the send button, it is determined as Yes in S204. When the passenger releases the transmission button, the determination in S204 is No. If it is determined No in S204, a stop command is transmitted from the mobile terminal 18 to the wireless communication device 24 (S205).

As shown in FIG. 4, when the wireless communication device 24 receives a stop command from the mobile terminal 18 communicating with the wireless communication device 24, S112 is determined as Yes. If it is determined as Yes in S112, the control device 14 determines whether or not an operation command has been received from the mobile terminal 18 (S109). That is, if the determination in S112 is Yes, the brake control unit 46 does not deactivate the brake device 13 unless the wireless communication device 24 receives the operation command from the mobile terminal 18 again.

When it is determined No in S112, the control device 14 determines whether or not the car 5 is placed in a specific rescue zone (S113). The rescue zone is preset. The position detection unit 47 detects that the car 5 has been placed in the rescue zone. The rescue zone includes locations where car 5 stops at landing 31 . The rescue zone may be the same as the landing zone. In such a case, the position detection section 47 detects that the car 5 is placed in the rescue zone based on the detection signal from the photoelectric sensor 32 .

When the position detection unit 47 detects that the car 5 is placed in the rescue zone after S109 is determined to be Yes, S113 is determined to be Yes. If it is determined as Yes in S113, the door control unit 48 controls the motor 22 to open the door 21 (S114). This allows passengers to get off the car 5 .

When the door 21 is opened in S114, the control device 14 determines whether or not the car 5 is unmanned (S115). A passenger detection unit 49 detects that the car 5 is unmanned. The passenger detection unit 49 may detect that the car 5 is unmanned based on the load measured by the weighing device 23 . If the car 5 is equipped with a camera, the passenger detection unit 49 may detect that the car 5 is unmanned using an image captured by the camera.

After the door 21 is opened in S114, when the passenger detection unit 49 detects that the car 5 is unmanned (Yes in S115), the door control unit 48 controls the motor 22 to close the door 21 (S116). Moreover, when it is determined as Yes in S115, the prohibiting unit 50 prohibits restarting of the elevator until a specific manual operation is performed (S117). The manual operation is an operation performed by maintenance personnel who arrive at the site. After the door 21 is closed in S116, the communication unit 52 may send a signal to the information center 4 indicating that the rescue process has ended.

In the example shown in the present embodiment, when a passenger is trapped in the car 5, the passenger can use his or her mobile terminal 18, which he or she is accustomed to using, to start a rescue operation. can. Passengers do not have to operate equipment they are not familiar with. For example, the passenger can move the car 5 by pairing his mobile terminal 18 with the wireless communication device 24 and pressing a send button displayed on the mobile terminal 18 .

This embodiment shows an example in which the control device 14 is provided with an automatic rescue operation function. The control device 14 may not have this function. In such a case, the processes shown in S102 to S105 are not performed. If it is determined as Yes in S101, the determination shown in S106 is performed. That is, when the confinement detection unit 41 detects confinement and the start condition is established, the communication control unit 44 outputs radio waves from the radio communication device 24 (S107). When the confinement detection unit 41 detects confinement and the start condition is established, the notification control unit 45 displays necessary information on the display 26 (S108).

Other functions that can be adopted by this system are described below. If possible, the system may employ several of the functions described below.

In the present embodiment, in S108, an example has been described in which information is displayed on the display 26 to the effect that the user will leave the door 21 when the send button is pressed. As another example, the transmission button may not be pushed until the passenger is away from the door 21.

In such a case, for example, the control device 14 further comprises a passenger detection section 51. The passenger detection unit 51 detects that there are no passengers in a specific range adjacent to the door 21 inside the car 5 . The range is preset. As an example, the range is a range in which the distance to the door 21 is 50 cm. If the car 5 is equipped with a camera, the passenger detection unit 51 may detect that there is no passenger in the range using the image captured by the camera.

In this example, if the passenger detection unit 51 detects that there is no passenger in the range before the determination shown in S109 is performed, the permission signal S3 is transmitted to the mobile terminal 18 communicating with the wireless communication device 24. be done. The permission signal S3 is a signal for permitting the mobile terminal 18 to transmit an operation command. This process of transmitting the permission signal S3 is performed after the information "leave the door" is displayed on the display 26 in S108 and before the determination shown in S109 is performed. That is, unless the permission signal S3 is transmitted, the determination shown in S109 is not performed.

After determining Yes in S201, the mobile terminal 18 determines whether or not the permission signal S3 has been received. The mobile terminal 18 can press the send button by receiving the permission signal S3 from the wireless communication device 24 . As an example, if the mobile terminal 18 does not receive the permission signal S3, the send button is not displayed. As another example, if the mobile terminal 18 does not receive the permission signal S3, the send button does not work. This allows the car 5 to start moving while the passenger is away from the door 21 .

The mobile terminal 18 may be provided with the function of detecting that the passenger has left the door 21 . For example, the mobile terminal 18 may detect that the passenger has left the door 21 based on the intensity of radio waves received from the wireless communication device 24 . As another example, if the mobile terminal 18 has an accelerometer, it may detect that the passenger has left the door 21 based on the acceleration measured by the accelerometer.

In the present embodiment, an example has been described in which the brake device 13 is deactivated and the car 5 is moved when S109 is determined to be Yes. At this time, the control device 14 may perform speed monitoring and abnormality monitoring. In this case, when the speed of the car 5 exceeds the reference speed, the brake control unit 46 operates the brake device 13 . Also, when a specific abnormality is detected, the brake control unit 46 operates the brake device 13 .
