[0022] 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.

[0023] Implementation method 1.

[0024] Figure 1 This is a diagram showing an example of an elevator system according to Embodiment 1. The elevator system includes an elevator device 1 , a server 2 , a mobile terminal 3 , and a terminal device 4 .

[0025] The elevator device 1 is connected to the server 2 via a network 5. As an example, the network 5 includes a dedicated line. The server 2 is installed in an information center remote from the elevator device 1. The server 2 can communicate with a plurality of elevator devices. The elevator device 1 is an example of an elevator device with which the server 2 can communicate.

[0026] The maintenance personnel are professional technicians assigned to the maintenance base 30. A plurality of maintenance personnel are assigned to the maintenance base 30. The maintenance base 30 manages a plurality of elevator devices. In the following description, the maintenance personnel in charge of the elevator device 1 are denoted by reference numeral "A" to distinguish them from other maintenance personnel.

[0027] The maintenance worker A holds a portable terminal 3. The maintenance worker A uses the portable terminal 3 to perform inspections on the elevator device 1. The portable terminal 3 can communicate with the elevator device 1 by wire or wirelessly. As an example, the portable terminal 3 is a smartphone. The portable terminal 3 may also be a tablet terminal. The portable terminal 3 may also be a dedicated terminal designed for inspections on the elevator device 1.

[0028] The terminal device 4 is installed in the call center 40. The terminal device 4 is operated by the operator B. The terminal device 4 can be connected to the server 2 and the portable terminal 3 via an Internet line or the like.

[0029] The elevator device 1 includes a car 11. The car 11 moves up and down in a shaft 12. The car 11 is suspended in the shaft 12 by means of a rope (not shown). The rope is hung on a traction machine (not shown). The car 11 is driven by the traction machine. The control device 13 controls the traction machine. That is, the movement of the car 11 is controlled by the control device 13. The control device 13 also controls the equipment provided in the car 11.

[0030] The monitoring device 14 is connected to the control device 13. The monitoring device 14 has a function for the elevator device 1 to communicate with external devices. The external devices include the server 2. That is, the monitoring device 14 communicates with the server 2 via the network 5.

[0031] A car room 11a is formed in the car 11. The car room 11a is a space for people to ride. The car 11 includes a display 16, a lamp 17, a camera 18, and a lamp 19. The display 16 is provided in the car room 11a. The display 16 is an example of a unit that provides information to people in the car room 11a. The lamp 17 illuminates the car room 11a. The display 16 and the lamp 17 are controlled by the control device 13.

[0032] The imaging device 18 is installed in the car 11 so as to be able to image the hoistway 12. The imaging device 18 is connected to the monitoring device 14 by wire or wirelessly. Figure 1 An example is shown in which the camera device 18 is provided on a downwardly-facing surface of a member forming the cage chamber 11a. Figure 1In the example shown, the image below the car 11 is captured by the camera 18. The lamp 19 is provided on the car 11 so as to emit light in the direction in which the camera 18 captures the image. In the case where the camera 18 is retrofitted to the existing elevator device 1, if the car 11 is already provided with a socket for a light bulb, power supply to the camera 18 and power supply to the lamp 19 can also be performed from the socket.

[0033] Figure 2 This is a diagram for explaining the functions of the elevator system. The server 2 includes a storage unit 21 and a communication unit 22. The portable terminal 3 includes a display 31 and an input device 32. The input device 32 is a device for the maintenance personnel A to input information. The display 31 and the input device 32 may also be an integrated device of a touch panel type. The terminal device 4 includes a display 41, an input device 42, a display control unit 43, an image request unit 44, a dispatch request unit 45, and an image providing unit 46. The input device 42 is a device for the operator B to input information. The display 41 and the input device 42 may also be an integrated device of a touch panel type.

[0034] The control device 13 includes an operation control unit 51 and a display control unit 52. The operation control unit 51 performs automatic operation, a first dedicated operation, and a second dedicated operation. The automatic operation is an operation for causing the car 11 to respond to registered elevator calls in sequence. The first dedicated operation and the second dedicated operation will be described later. The display control unit 52 controls the display 16. The monitoring device 14 includes a storage unit 61, a communication unit 62, an operation instruction unit 63, a camera control unit 64, and an image acquisition unit 65. The camera control unit 64 controls the camera 18.

[0035] The user at the landing 6 gets on the car 11 when the car 11 stops at the landing 6. The user riding in the car 11 gets off the car 11 when the car 11 stops at the landing 6. When the car 11 stops at the landing 6, a gap is formed between the sill provided in the car 11 and the sill provided at the landing 6. Therefore, when the user drops an object when riding in the car 11 or getting off the car 11, the object may fall into the hoistway 12 through the gap.

[0036] See also below Figures 3 to 7 , the actions performed when user D drops items such as keys, documents or cash into the shaft 12 are described in detail.

[0037] User D who dropped an item into the shaft 12 contacts the call center 40. For example, the telephone number of the call center 40 is recorded on a guide plate provided at the landing 6. User D calls the call center 40 after seeing the record. Operator B answers the call at the call center 40. User D informs operator B of the situation that the item was dropped into the shaft 12 and the identification number of the elevator device 1. The identification number is a number for identifying the elevator device 1. The identification number and the telephone number of the call center 40 are recorded on the guide plate together.

[0038] Figure 3 and Figure 4 It is a flowchart showing an example of the operation of the terminal device 4. Figure 3 and Figure 4 A series of operations are shown. In the terminal device 4, it is determined whether the identification number is input (S101). When the operator B who is contacted by the user D inputs the identification number of the elevator device 1 using the input device 42, it is determined as "yes" in S101. When it is determined as "yes" in S101, the display control unit 43 displays information related to the elevator device 1 on the display 41 (S102).

[0039] Next, in the terminal device 4, it is determined whether a specific start condition is established (S103). The start condition is a condition for starting an action for finding a dropped object that has fallen into the shaft 12. The start condition is preset. For example, in S102, a start button is displayed on the display 41. When operator B presses the start button using the input device 42, the start condition is established. When operator B receives a contact about a dropped object that has fallen into the shaft 12 from user D, he presses the start button. Thus, it is determined to be "yes" in S103.

[0040] The image request unit 44 has a function of making an image request R1 to the elevator device 1 when receiving a communication about a dropped object dropped into the shaft 12. The image request R1 is a request for causing the camera 18 to capture an image of the shaft 12. When it is determined as "yes" in S103, the image request unit 44 sends the image request R1 to the server 2 (S104).

[0041] The dispatch request unit 45 has a function of making a dispatch request for dispatching a maintenance person to the elevator device 1 when the image request R1 is made. When it is determined as "yes" in S103, the dispatch request unit 45 sends a dispatch request to the maintenance base 30 (S105). The dispatch request includes information indicating that a dropped object has fallen into the shaft 12 and information indicating the identification number of the elevator device 1. In the maintenance base 30, upon receiving the dispatch request, the maintenance person A goes to the site of the elevator device 1 with the portable terminal 3.

[0042] Figure 52 is a flowchart showing an example of the operation of the server 2. In the server 2, it is determined whether the image request R1 is received from the terminal device 4 of the call center 40 (S201). When the communication unit 22 receives the image request R1 sent from the terminal device 4 in S104, it is determined as "yes" in S201. When it is determined as "yes" in S201, the communication unit 22 forwards the received image request R1 to the monitoring device 14 (S202). That is, in the example shown in this embodiment, the image request unit 44 makes an image request R1 to the elevator device 1 via the server 2.

[0043] Figure 6 1 is a flowchart showing an example of the operation of the monitoring device 14. In the monitoring device 14, it is determined whether the image request R1 is received from the server 2 (S301). When the communication unit 62 receives the image request R1 transmitted from the server 2 in S202, it is determined as "yes" in S301.

[0044] When the monitoring device 14 receives the image request R1, the operation command unit 63 causes the control device 13 to perform the first dedicated operation according to the received image request R1. The first dedicated operation is an operation for stopping the car 11 at a specific first shooting position. The first shooting position is preset. As an example, the first shooting position is the lowermost landing 6. For example, when the operation command unit 63 determines "yes" in S301, the operation command C1 is sent to the control device 13 (S302).

[0045] When the monitoring device 14 receives the image request R1 (Yes in S301), the camera control unit 64 causes the camera 18 to perform image capture in accordance with the received image request R1 (S303). When the camera 18 starts capturing, the lamp 19 lights up.

[0046] Figure 7 4 is a flowchart showing an example of the operation of the control device 13. The control device 13 determines whether the operation command C1 is received from the monitoring device 14 (S401). When the control device 13 receives the operation command C1 sent from the monitoring device 14 in S302, the determination in S401 is "YES".

[0047] When it is determined as "yes" in S401, the operation control unit 51 performs the first dedicated operation (S402). For example, when it is determined as "yes" in S401, the operation control unit 51 moves the car 11 toward the first imaging position. When the car 11 reaches the first imaging position, the operation control unit 51 stops the car 11 at the first imaging position.

[0048] like Figure 6As shown, in the monitoring device 14, when the operation command C1 is sent in S302, it is determined whether the car 11 has stopped at the first shooting position (S304). When the car 11 stops at the first shooting position in the first dedicated operation shown in S402, it is determined as "yes" in S304. In addition, the processing shown in S303 can also be performed after S304. That is, the shooting of the camera device 18 can also be started by determining "yes" in S304.

[0049] When it is determined as "yes" in S304, the image acquisition unit 65 acquires the image captured by the camera 18 (S305). That is, in S305, the image acquisition unit 65 acquires the image of the shaft 12 captured by the camera 18 when the car 11 stops at the first shooting position in the first dedicated operation. In the following content, the image acquired by the image acquisition unit 65 in S305 is also referred to as the first image. The first image includes an image obtained by shooting the bottom pit of the shaft 12 from above.

[0050] The communication unit 62 transmits the first image acquired by the image acquisition unit 65 to the server 2 ( S306 ).

[0051] like Figure 5 As shown, in the server 2, when the image request R1 is sent in S202, it is determined whether the first image is received from the monitoring device 14 (S203). When the communication unit 22 receives the first image sent from the monitoring device 14 in S306, it is determined as "yes" in S203. The first image received from the monitoring device 14 in S203 is stored in the storage unit 21 (S204). In addition, when it is determined as "yes" in S203, the communication unit 22 sends the first acquisition information indicating that the first image has been acquired to the terminal device 4 as a response to the image request R1 (S205).

[0052] like Figure 3 As shown, in the terminal device 4, when the image request R1 is sent in S104, it is determined whether the first acquisition information is received from the server 2 as a response (S106). When the terminal device 4 receives the first acquisition information sent from the server 2 in S205, it is determined as "yes" in S106. When it is determined as "yes" in S106, the display control unit 43 displays the first image stored in the storage unit 21 of the server 2 on the display 41 (S107).

[0053] When the first image is displayed on the display 41, the terminal device 4 determines whether a specific first condition is satisfied (S108). When it is determined as "No" in S108, the terminal device 4 determines whether a specific second condition is satisfied (S109). The first condition is a condition for starting an action to be performed when the operator B finds the dropped object from the first image. The second condition is a condition for starting an action to be performed when the operator B fails to find the dropped object from the first image.

[0054] Operator B looks for the dropped object by viewing the first image displayed on the display 41, i.e., the image of the pit of the shaft 12. As an example, if operator B can find the dropped object from the first image, he presses the confirmation button displayed on the display 41. Thus, the first condition is established ("Yes" of S108). In addition, if operator B fails to find the dropped object from the first image, he presses the image acquisition button displayed on the display 41. Thus, the second condition is established ("Yes" of S109). In addition, the first condition or the second condition may also be established by other operations performed by operator B using the input device 42.

[0055] When it is determined as "yes" in S108, the image providing unit 46 provides the first image stored in the storage unit 21 of the server 2 to the car 11 (S110). As a result, the first image stored in the storage unit 21 of the server 2 is displayed on the display 16. That is, by pressing the confirmation button, the first image is provided from the server 2 to the control device 13 via the monitoring device 14. The display control unit 52 displays the first image received from the server 2 on the display 16.

[0056] When the operator B presses the confirmation button, the operator contacts the user D to let him / her view the display 16. Then, the operator B asks the user D whether the dropped object found by the operator B is consistent with the object dropped by the user D. If the dropped object found by the operator B is consistent with the object dropped by the user D, the operator B presses the notification button displayed on the display 41.

[0057] When the notification button is pressed, the image providing unit 46 provides the first image stored in the storage unit 21 of the server 2 to the maintenance worker A (S111). As a result, the first image is displayed on the display 31 of the portable terminal 3 of the maintenance worker A who has been dispatched in response to the dispatch request. At this time, the first image may be directly sent from the server 2 to the portable terminal 3. The first image may also be sent to the portable terminal 3 via the terminal device 4.

[0058] On the other hand, if it is determined to be "yes" in S109, the image request unit 44 sends an image request R2 to the server 2 (S112). Image request R2 is a request for the camera 18 to capture an image of the shaft 12, similarly to image request R1. Image request R2 requests an enlarged image of the pit of the shaft 12.

[0059] like Figure 5 As shown, in the server 2, when the first acquisition information is transmitted in S205, it is determined whether the image request R2 is received from the terminal device 4 (S206). When the communication unit 22 receives the image request R2 transmitted from the terminal device 4 in S112, it is determined as "yes" in S206. When it is determined as "yes" in S206, the communication unit 22 forwards the received image request R2 to the monitoring device 14 (S207). That is, in the example shown in this embodiment, the image request unit 44 makes the image request R2 to the elevator device 1 via the server 2.

[0060] like Figure 6 As shown, in the monitoring device 14, when the first image is transmitted in S306, it is determined whether the image request R2 is received from the server 2 (S307). When the communication unit 62 receives the image request R2 transmitted from the server 2 in S207, it is determined as "yes" in S307.

[0061] When the monitoring device 14 receives the image request R2, the operation command unit 63 causes the control device 13 to perform the second special operation according to the received image request R2. The second special operation is an operation for stopping the car 11 at a specific second shooting position that is lower than the first shooting position. The second shooting position is preset. As an example, the second shooting position is the lowest position to which the car 11 can move. For example, a switch for limiting the downward movement of the car 11 is provided in the hoistway 12. The second shooting position is the position where the switch is actuated. When it is determined as "yes" in S307, the operation command unit 63 sends the operation command C2 to the control device 13 (S308).

[0062] like Figure 7 As shown, after the first dedicated operation is performed, the control device 13 determines whether the operation command C2 is received from the monitoring device 14 (S403). When the control device 13 receives the operation command C2 sent from the monitoring device 14 in S308, the determination in S403 is "YES".

[0063] When it is determined as "yes" in S403, the operation control unit 51 performs the second special operation (S404). For example, when it is determined as "yes" in S403, the operation control unit 51 moves the car 11 downward from the lowermost floor station 6. When the car 11 reaches the second shooting position, the operation control unit 51 stops the car 11 at the second shooting position. In addition, the operation control unit 51 can also turn off the light 17 during the second special operation. After the operation control unit 51 stops the car 11 at the second shooting position for a predetermined time, the operation control unit 51 moves the car 11 upward to the lowermost floor station 6.

[0064] like Figure 6 As shown in FIG. 1 , in the monitoring device 14, when the operation command C2 is sent in S308, it is determined whether the car 11 has stopped at the second shooting position (S309). When the car 11 stops at the second shooting position in the second dedicated operation shown in S404, it is determined as "yes" in S309. In addition, during the second dedicated operation, the lamp 19 is also lit, and the camera 18 takes pictures.

[0065] When it is determined as "yes" in S309, the image acquisition unit 65 acquires the image captured by the camera 18 (S310). That is, in S310, the image acquisition unit 65 acquires the image of the shaft 12 captured by the camera 18 when the car 11 stops at the second shooting position in the second dedicated operation. In the following content, the image acquired by the image acquisition unit 65 in S310 is also referred to as the second image. The second image includes an image obtained by shooting the pit of the shaft 12 from above. The second image includes an enlarged image of the pit.

[0066] The communication unit 62 transmits the second image acquired by the image acquisition unit 65 to the server 2 ( S311 ).

[0067] like Figure 5 As shown, in the server 2, when the image request R2 is sent in S207, it is determined whether the second image is received from the monitoring device 14 (S208). When the communication unit 22 receives the second image sent from the monitoring device 14 in S311, it is determined as "yes" in S208. The second image received from the monitoring device 14 in S208 is stored in the storage unit 21 (S209). In addition, when it is determined as "yes" in S208, the communication unit 22 sends the second acquisition information indicating that the second image has been acquired to the terminal device 4 as a response to the image request R2 (S210).

[0068] like Figure 4As shown, in the terminal device 4, when the image request R2 is sent in S112, it is determined whether the second acquisition information is received from the server 2 as a response (S113). When the terminal device 4 receives the second acquisition information sent from the server 2 in S210, it is determined as "yes" in S113. When it is determined as "yes" in S113, the display control unit 43 displays the second image stored in the storage unit 21 of the server 2 on the display 41 (S114).

[0069] When the second image is displayed on the display 41, the terminal device 4 determines whether a specific third condition is satisfied (S115). The third condition is a condition for starting an operation to be performed when the operator B finds the dropped object from the second image.

[0070] Operator B looks for the dropped object by viewing the second image displayed on the display 41, that is, the enlarged image of the pit of the shaft 12. As an example, if operator B can find the dropped object from the second image, he presses the confirmation button displayed on the display 41. Thus, the third condition is established ("Yes" in S115). In addition, the second condition can also be established by other operations performed by operator B using the input device 42.

[0071] The processing shown in S116 after the determination of "yes" in S115 is the same as that in Figure 3 The processing shown in S110 is the same as that shown in S117. Figure 3 When it is determined as "yes" in S115, the image providing unit 46 provides the second image stored in the storage unit 21 of the server 2 to the car 11 (S116). As a result, the second image stored in the storage unit 21 of the server 2 is displayed on the display 16.

[0072] Then, the operator B asks the user D whether the dropped object found by the operator B matches the object dropped by the user D. If the dropped object found by the operator B matches the object dropped by the user D, the operator B presses the notification button displayed on the display 41 .

[0073] When the notification button is pressed, the image providing unit 46 provides the second image stored in the storage unit 21 of the server 2 to the maintenance worker A (S117). As a result, the second image is displayed on the display 31 of the mobile terminal 3 of the maintenance worker A who has been dispatched in response to the dispatch request.

[0074] In the example shown in the present embodiment, the first image or the second image showing the dropped object is sent to the portable terminal 3 of the maintenance personnel A who receives the dispatch request and is heading to the site of the elevator device 1. The maintenance personnel A can grasp the appearance and the position of the dropped object based on the first image or the second image sent to the portable terminal 3 before arriving at the site. Therefore, in the example shown in the present embodiment, the time until the maintenance personnel A finds the dropped object dropped in the hoistway 12 can be shortened. In addition, in order for the maintenance personnel A to pick up the dropped object, the service of the elevator device 1 must be stopped. In the example shown in the present embodiment, the time of stopping the service can also be shortened.

[0075] In this embodiment, an example of performing the process shown in S110 before performing the process shown in S111 is described. As another example, the process shown in S110 may not be performed. In this case, when it is determined as "yes" in S108, the process shown in S111 is performed. Similarly, the process shown in S116 may not be performed. In this case, when it is determined as "yes" in S115, the process shown in S117 is performed.

[0076] In the present embodiment, an example in which automatic operation is not performed during the first dedicated operation and the second dedicated operation is described. As another example, automatic operation may be performed with priority over the first dedicated operation and the second dedicated operation. In this case, for example, in the monitoring device 14, even if it is determined as "yes" in S301, if there is no elevator call and the car 11 has not been unmanned for a predetermined time, the processing shown in S302 is not started. In addition, when an elevator call occurs while the first dedicated operation is being performed, the first dedicated operation is interrupted and automatic operation is started. Similarly, when an elevator call occurs while the second dedicated operation is being performed, the second dedicated operation is interrupted and automatic operation is started. Automatic operation may also be prioritized by other methods.

[0077] Figure 8 1 is a diagram showing an example of hardware resources of the terminal device 4. The terminal device 4 includes a processing circuit 80 including a processor 81 and a memory 82 as hardware resources. The processing circuit 80 may include a plurality of processors 81. The processing circuit 80 may include a plurality of memories 82.
