[0020] The following is a detailed description with reference to the accompanying drawings. The repeated description is appropriately simplified or omitted. In each figure, the same reference numeral represents the same part or a corresponding part.

[0021] Implementation Method 1

[0022] Figure 1 1 is a diagram showing an example of a system including an elevator device 1 in Embodiment 1. The elevator device 1 is connected to a remote information center 4 where an operator is located via a network 2. As an example, the network 2 is an IP network. The IP network is a communication network that uses IP (Internet Protocol) as a communication protocol. The network 2 may be a closed network or an open network. The information center 4 manages a plurality of elevator devices. The elevator device 1 is an example of an elevator device managed by the information center 4.

[0023] The elevator device 1 includes a car 5 and a counterweight 6. The car 5 moves up and down in a hoistway 7. The car 5 and the counterweight 6 are suspended in the hoistway 7 by means of a rope 8. The counterweight 6 moves up and down in the hoistway 7 in a direction opposite to the direction in which the car 5 moves. Figure 1 An example of an elevator apparatus using a 1:1 roping method is shown.

[0024] The hoisting machine 9 drives the car 5. The hoisting machine 9 includes a sheave 10, a motor 11, and an encoder 12 ( Figure 1 (not shown) and a braking device 13.

[0025] The sheave 10 is rotatably supported by the frame of the hoisting machine 9. The rope 8 is hung around the sheave 10. The motor 11 generates a 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.

[0026] The brake device 13 is a device for keeping the car 5 stationary. The brake device 13 blocks the rotation of the sheave 10 when in operation. If the brake device 13 is not in operation, the sheave 10 can rotate. Hereinafter, regarding the brake device 13, the expression "operation" is used to indicate a state in which the brake device 13 performs its function, that is, a state in which the rotation of the sheave 10 is blocked. Regarding the brake device 13, the expression "non-operation" is used to indicate a state in which the brake device 13 does not perform its function, that is, a state in which the rotation of the sheave 10 is not blocked.

[0027] As an example, the brake device 13 includes a rotating body and a brake shoe. The rotating body rotates in conjunction with the sheave 10. The brake shoe is configured to be movable in a manner of contacting and separating from the rotating body. Resistance to the rotation of the sheave 10 is generated by pressing the brake shoe against the rotating body. In such a brake device 13, when power is supplied to the brake device 13, the brake shoe is separated from the rotating body, and the brake device 13 does not operate. That is, the brake device 13 is released. When the power to the brake device 13 is cut off, the brake shoe is pressed against the rotating body, and the brake device 13 operates.

[0028] The control device 14 controls the hoisting machine 9. That is, the movement of the car 5 is controlled by the control device 14. The monitoring device 15 is connected to the control device 14. The monitoring device 15 communicates with the information center 4 via the network 2.

[0029] Figure 1 The example in which the hoisting machine 9 and the control device 14 are installed in the machine room 16 above the hoistway 7 is shown. The hoisting machine 9 and the control device 14 may also be installed in the hoistway 7. The hoisting machine 9 may be installed at the top of the hoistway 7 or in the pit of the hoistway 7.

[0030] The car 5 and the control device 14 are connected by a control cable 17. The equipment provided in the car 5 is controlled by the control device 14. The car 5 includes a door 21, a motor 22, a weighing device 23, a wireless communicator 24, and an operating panel 25.

[0031] The entrance and exit of the car 5 are opened and closed by a door 21. A motor 22 generates a driving force for driving the door 21. A weighing device 23 measures the load carried by the car 5. Figure 1 The example in which the weighing device 23 is installed at the lower part of the car 5 is shown. The weighing device 23 may be installed at the end of the rope 8.

[0032] The wireless communicator 24 is a device for wirelessly communicating with other devices present in the car 5. For example, the wireless communicator 24 wirelessly communicates with a portable terminal 18 held by a passenger using a specific communication standard such as Bluetooth (registered trademark). As an example, the portable terminal 18 is a smartphone. Figure 1 An example is shown in which the wireless communicator 24 is built in the operation panel 25 .

[0033] The operating panel 25 includes a display 26 and buttons 27. The display 26 is an example of a notification device for providing information to passengers in the car 5. The operating panel 25 may also include a speaker as a notification device. The operating panel 25 may also include both the display 26 and the speaker as notification devices. The buttons 27 include a destination button, a door opening button, and a door closing button. The buttons 27 may also include other buttons.

[0034] The elevator device 1 is provided with a landing device for detecting that the car 5 is arranged in a specific landing area. The landing area is pre-set in accordance with the height of each landing 31. For example, the landing area set in accordance with the height of the landing 31 of the Nth floor includes the position where the car 5 stops at the landing 31 of the Nth floor. The position where the car 5 stops at the landing 31 of the Nth floor refers to the position of the car 5 so that the height of the floor of the landing 31 of the Nth floor is the same as the height of the floor of the car 5.

[0035] As an example, the floor stop device includes a photoelectric sensor 32 and a plate 33. The photoelectric sensor 32 is provided on the car 5. The plate 33 is provided on the shaft 7. The plate 33 is configured to match the height of each landing station 31. The range in which the photoelectric sensor 32 can detect the plate 33 configured to match the height of the landing station 31 of the Nth floor is the floor stop area of ​​the Nth floor. When the photoelectric sensor 32 detects the plate 33, a detection signal corresponding to the detected plate 33 is sent from the photoelectric sensor 32 to the control device 14.

[0036] Figure 2 1 is a diagram for explaining the functions of the control device 14 and the monitoring device 15. Figure 2 As shown, the control device 14 includes a staircase 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, a door control unit 48, a passenger detection unit 49, a prohibition unit 50, and a passenger detection unit 51. The monitoring device 15 includes a communication unit 52.

[0037] Below, also refer to Figures 3 to 5 , the operation of this system is explained in detail. Figure 3 and Figure 4 It is a flowchart showing an operation example of the control device 14 and the monitoring device 15 . Figure 3 and Figure 4 Shows a series of actions.

[0038] In the control device 14, it is determined whether the passenger is trapped in the elevator in the car 5 (S101). The situation that the passenger is trapped in the elevator is detected by the elevator detection unit 41. The elevator detection unit 41 can also detect the passenger's elevator trapping by using the load measured by the weighing device 23. If the elevator 5 is equipped with a camera device, the elevator detection unit 41 can also detect the passenger's elevator trapping by using the image captured by the camera device.

[0039] When the elevator detection unit 41 detects an elevator trap, it is determined as "yes" in S101. When it is determined as "yes" in S101, the communication unit 52 sends an elevator trap signal to a server provided in the information center 4 (S102). The server is an example of an external device. The communication unit 52 sends an elevator trap signal to a specific external device in S102.

[0040] In the information center 4 that receives the trapped elevator signal, the operator determines whether the automatic rescue operation can be performed in the elevator device 1. When the operator confirms that there is no problem in performing the automatic rescue operation, the server sends a permission signal S1 to the elevator device 1 as a response to the trapped elevator signal. When the operator determines that there is a problem in performing the automatic rescue operation, the server sends a disallowance signal S2 to the elevator device 1 as a response to the trapped elevator signal.

[0041] When the trapped elevator signal is transmitted in S102, the control device 14 determines whether a disapproval signal S2 is received from the server (S103). When the determination in S103 is "No", the control device 14 determines whether a permission signal S1 is received from the server (S104).

[0042] When the communication unit 52 receives the permission signal S1 from the server in response to the trapped elevator signal sent in S102, it is determined as "yes" in S104. When it is determined as "yes" in S104, the operation control unit 42 starts the automatic rescue operation (S105). The automatic rescue operation is an operation for rescuing passengers trapped in the elevator car 5. When the automatic rescue operation starts, the operation control unit 42 automatically performs specific actions required for passenger rescue.

[0043] On the other hand, when the communication unit 52 receives the disallowed signal S2 from the server in response to the trapped elevator signal sent in S102, it is determined as "yes" in S103. When it is determined as "yes" in S103, the operation control unit 42 does not start the automatic rescue operation. That is, when it is determined as "yes" in S103, the automatic rescue operation is not performed. When it is determined as "yes" in S103, the condition determination unit 43 determines whether a specific start condition is met (S106). The start condition is a condition for starting a rescue operation using the passenger's portable terminal 18. The start condition is pre-set.

[0044] As an example, if the abnormality that causes the elevator entrapment is a specific abnormality, the start condition is not met. The above-mentioned specific abnormality may also include a brake slip abnormality. When the sheave 10 is still rotating although the brake device 13 is in operation, the brake slip abnormality is detected. The rotation of the sheave 10 is detected based on the signal from the encoder 12. The above-mentioned specific abnormality may also include a traction abnormality. When the position of the car 5 changes although the sheave 10 is not rotating, the traction abnormality is detected. The above-mentioned specific abnormality may also include other abnormalities such as abnormalities in the operation of the safety circuit and abnormalities in the inverter. Figure 3 In the example shown, the start condition includes the communication unit 52 receiving a non-permission signal S2 as a response to the elevator signal from the server. Figure 3 In the example shown, if the communication unit 52 does not receive the non-permission signal S2 from the server, the start condition is not satisfied.

[0045] When the start condition is satisfied, it is determined as "yes" in S106. When it is determined as "yes" in S106, the communication control unit 44 outputs radio waves for communicating with the portable terminal 18 from the wireless communicator 24 (S107). In addition, when it is determined as "yes" in S106, the notification control unit 45 displays information for the portable terminal 18 to communicate with the wireless communicator 24 on the display 26 (S108). The passenger trapped in the elevator car 5 can connect the portable terminal 18 to the wireless communicator 24 by operating his own portable terminal 18 while viewing the content displayed on the display 26.

[0046] Figure 5 1 is a flowchart showing an example of the operation of the portable terminal 18. It is preferred that an application for an elevator is pre-installed in the portable terminal 18. In the following description, the application is referred to as "application A". As an example, when the portable terminal 18 receives the radio wave output from the wireless communicator 24 in S107, the application A is automatically started. When the application A is started, it is determined in the portable terminal 18 whether it is connected to the wireless communicator 24 (S201).

[0047] The passenger can obtain information for connecting the portable terminal 18 with the wireless communicator 24 by viewing the content displayed on the display 26 in S108. As an example, a password for connecting with the wireless communicator 24 is displayed on the display 26. As another example, a QR code for connecting with the wireless communicator 24 may be displayed on the display 26. The passenger can connect the portable terminal 18 with the wireless communicator 24 by inputting the password displayed on the display 26 or photographing the QR code. When the portable terminal 18 is connected with the wireless communicator 24, it is determined as "yes" in S201.

[0048] If it is determined as "yes" in S201, it is determined whether a send button for sending an action command is pressed in the portable terminal 18 (S202). As an example, in application A, when the portable terminal 18 is connected to the wireless communicator 24, the send button is displayed on the display of the portable terminal 18.

[0049] In S108, the following information may be displayed on the display 26 of the car 5.

[0050] ·Leave the door with the send button pressed.

[0051] By continuously pressing the send button, the car moves to the nearby floor.

[0052] ·The car stops when your finger leaves the send button.

[0053] After the door opens, check outside and leave the car.

[0054] The passenger in the car 5 understands that pressing the send button moves the car 5 by viewing the content displayed on the display 26. When the passenger presses the send button on his / her portable terminal 18 (Yes in S202), an operation command is transmitted from the portable terminal 18 to the wireless communicator 24 (S203).

[0055] like Figure 4 As shown, in the control device 14, when it is determined as "yes" in S106, it is determined whether an action instruction is received from the portable terminal 18 (S109). When the wireless communicator 24 receives an action instruction from the portable terminal 18 that is communicating with the wireless communicator 24, it is determined as "yes" in S109. When it is determined as "yes" in S109, in the control device 14, according to the instruction from the passenger trapped in the car 5, a rescue process for rescuing the passenger is started.

[0056] In the rescue process, first, the brake control unit 46 deactivates the brake device 13 (S110). As a result, if the car 5 is lighter than the counterweight 6, the car 5 moves upward. If the car 5 is heavier than the counterweight 6, the car 5 moves downward. For example, the brake control unit 46 repeatedly deactivates the brake device 13 for a specified time during the rescue process. The specified 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). As a result, the car 5 stops.

[0057] When it is determined as YES in S109 , the control device 14 determines whether a stop instruction has been received from the portable terminal 18 ( S112 ).

[0058] like Figure 5As shown, in the portable terminal 18, when the action command is sent to the wireless communicator 24 in S203, it is determined whether the send button is pressed (S204). If the passenger continues to press the send button, it is determined as "yes" in S204. When the passenger's finger is released from the send button, it is determined as "no" in S204. When it is determined as "no" in S204, a stop command is sent from the portable terminal 18 to the wireless communicator 24 (S205).

[0059] like Figure 4 As shown, when the wireless communicator 24 receives the stop command from the portable terminal 18 that is communicating with the wireless communicator 24, it is determined as "yes" in S112. When it is determined as "yes" in S112, the control device 14 determines whether an operation command is received from the portable terminal 18 (S109). That is, when it is determined as "yes" in S112, if the wireless communicator 24 does not receive the operation command from the portable terminal 18 again, the brake control unit 46 does not deactivate the brake device 13.

[0060] When it is determined as "No" in S112, the control device 14 determines whether the car 5 is configured in a specific rescue area (S113). The rescue area is preset. The position detection unit 47 detects that the car 5 is configured in the rescue area. The rescue area includes the position where the car 5 stops at the floor station 31. The rescue area can also be the same as the landing area. In this case, the position detection unit 47 detects that the car 5 is configured in the rescue area based on the detection signal from the photoelectric sensor 32.

[0061] When the position detection unit 47 detects that the car 5 is located in the rescue area after the determination in S109 is "Yes", the determination in S113 is "Yes". When the determination in S113 is "Yes", the door control unit 48 controls the motor 22 to open the door 21 (S114). Thus, the passenger can get off the car 5.

[0062] When the door 21 is opened in S114, the control device 14 determines whether the car 5 is empty (S115). The passenger detection unit 49 detects that the car 5 is empty. The passenger detection unit 49 may detect that the car 5 is empty 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 empty using an image captured by the camera.

[0063] When the passenger detection unit 49 detects that there is no one in the car 5 after the door 21 is opened in S114 ("Yes" in S115), the door control unit 48 controls the motor 22 to close the door 21 (S116). In addition, when it is determined to be "Yes" in S115, the prohibition unit 50 prohibits the restart of the elevator until a specific manual operation is performed (S117). The manual operation is performed by the maintenance personnel who arrive at the scene. After the door 21 is closed in S116, the communication unit 52 may also send a signal to the information center 4 indicating that the rescue process has been completed.

[0064] According to the example shown in this embodiment, when a passenger is trapped in the car 5, the passenger can start the rescue operation using his / her own portable terminal 18 that he / she is used to using. The passenger does not need to operate an unfamiliar device. For example, the passenger can move the car 5 by pairing his / her own portable terminal 18 with the wireless communicator 24 and pressing the send button displayed on the portable terminal 18.

[0065] In the present embodiment, an example is shown in which the control device 14 has an automatic rescue operation function. The control device 14 may not have this function. In this case, the processing shown in S102 to S105 is not performed. When it is determined as "yes" in S101, the determination shown in S106 is performed. That is, if the starting condition is met when the ladder detection unit 41 detects that the ladder is trapped, the communication control unit 44 outputs radio waves from the wireless communicator 24 (S107). In addition, if the starting condition is met when the ladder detection unit 41 detects that the ladder is trapped, the notification control unit 45 displays the required information on the display 26 (S108).

[0066] The following describes other functions that can be used in this system. In this system, if possible, multiple functions shown below can also be used.

[0067] In the present embodiment, an example is described in which, in S108, information indicating that the passenger has left the door 21 when the send button is pressed is displayed on the display 26. As another example, if the passenger has not left the door 21, the send button may not be pressed.

[0068] In this case, for example, the control device 14 further includes a passenger detection unit 51. The passenger detection unit 51 detects that there is no passenger 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 of 50 cm from the door 21. If the car 5 is equipped with a camera, the passenger detection unit 51 can also detect that there is no passenger in the range by using an image captured by the camera.

[0069] In this example, when the passenger detection unit 51 detects that there is no passenger within the range before the determination shown in S109 is performed, the permission signal S3 is transmitted to the portable terminal 18 that is communicating with the wireless communicator 24. The permission signal S3 is a signal for permitting the transmission of an action command to the portable terminal 18. This process of transmitting the permission signal S3 is performed after the information indicating the meaning of "leaving the door" is displayed on the display 26 in S108 and before the determination shown in S109 is performed. That is, if the permission signal S3 is not transmitted, the determination shown in S109 is not performed.

[0070] In the portable terminal 18, after the determination in S201 is "yes", it is determined whether the permission signal S3 is received. In the portable terminal 18, the send button can be pressed according to the receipt of the permission signal S3 from the wireless communicator 24. As an example, in the portable terminal 18, if the permission signal S3 is not received, the send button is not displayed. As another example, in the portable terminal 18, if the permission signal S3 is not received, the send button does not function. In this way, the movement of the car 5 can be started when the passenger leaves the door 21.

[0071] The portable terminal 18 may also have a function of detecting that a passenger has left the door 21. For example, the portable terminal 18 may detect that a passenger has left the door 21 based on the strength of the radio wave received from the wireless communicator 24. As another example, if the portable terminal 18 has an accelerometer, the portable terminal 18 may detect that a passenger has left the door 21 based on the acceleration measured by the accelerometer.

[0072] In the present embodiment, an example is described in which, when it is determined to be "yes" in S109, the brake device 13 is not actuated and the car 5 is moved. At this time, speed monitoring and abnormality monitoring may also be performed in the control device 14. In this case, when the speed of the car 5 exceeds the reference speed, the brake control unit 46 actuates the brake device 13. In addition, when a specific abnormality is detected, the brake control unit 46 actuates the brake device 13.
