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 an elevator device according to Embodiment 1. FIG. The elevator system comprises a car 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3 . A counterweight 2 moves up and down the hoistway 3 . A car 1 and a counterweight 2 are suspended in a hoistway 3 by ropes 4 . As an example, the rope 4 is a wire rope.

The rope 4 is wound around the hoist 5. A hoist 5 drives the car 1 . The control device 6 controls the hoist 5 . That is, movement of the car 1 is controlled by the control device 6 .

FIG. 1 shows an example in which the hoisting machine 5 and the control device 6 are installed in the machine room 7 above the hoistway 3 . The hoisting machine 5 and the control device 6 may be installed in 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 may be installed in the pit of the hoistway 3 .

The communication device 8 is connected to the control device 6. The communication device 8 is a device for the elevator device to communicate with the outside. A communication device 8 communicates with the outside via a network 9 . The exterior includes a remote monitoring center 10 or the like that monitors the elevator system.

A car 1 is provided with a camera 11 and a lamp 12. FIG. 1 shows an example in which a camera 11 is provided on a support frame 13 provided on a car 1. As shown in FIG. For example, the camera 11 is provided on the downward surface of the support frame 13 . In such a case, an image below the car 1 is taken by the camera 11 . If the car 1 is equipped with a socket for a light bulb, the power supply to the camera 11 may be from this socket.

The camera 11 may be provided above the car 1. In such a case, an image above the car 1 is taken by the camera 11 . FIG. 1 shows an example in which cameras 11 are provided both above and below the car 1 . The camera 11 may be provided at the top of the hoistway 3, in the pit, or in the machine room 7. A worker who inspects the elevator device often works on the car 1 . For this reason, it is preferable that the camera 11 be provided so as to be able to photograph the worker on top of the car 1 .

FIG. 1 shows an example in which a worker brings an information processing terminal 15 to the hall 14 where the car 1 stops. The worker uses the information processing terminal 15 to check the elevator device. The information processing terminal 15 is, for example, a smart phone. The information processing terminal 15 may be a tablet terminal. The information processing terminal 15 may be a dedicated terminal designed for inspection of the elevator system.

FIG. 2 is a diagram for explaining the functions of the information processing terminal 15. FIG. The information processing terminal 15 includes a display device 20 , a storage unit 21 , a communication unit 22 , a detection unit 23 , a specification unit 24 and a creation unit 25 .

Workers regularly inspect the elevator equipment. After inspecting the elevator device, the worker prepares a work report regarding the inspection using the information processing terminal 15 . The work report includes multiple report items such as overall findings and inspection results of each part. In the example shown in this embodiment, the image captured by the camera 11 is used for the work report. The operation performed during inspection will be described in detail below with reference to FIG. 3 as well. FIG. 3 is a flowchart showing an operation example of the information processing terminal 15. As shown in FIG.

The information processing terminal 15 determines whether or not it is connected to the control device 6 (S101). A worker connects the information processing terminal 15 to the control device 6 when inspecting the elevator device. The information processing terminal 15 may be connected to the control device 6 by wire or wirelessly. When the information processing terminal 15 is connected to the control device 6 (Yes in S101), the communication unit 22 receives various signals necessary for inspection from the control device 6 (S102).

Also, the information processing terminal 15 determines whether or not the data of the image captured by the camera 11 has been received (S103). The communication unit 22 receives the data of the image captured by the camera 11 from the control device 6 (Yes in S103). As another example, the communication section 22 may directly receive the image data from the camera 11 . The image data received by the communication unit 22 is stored in the storage unit 21 (S104).

Based on the image data stored in the storage unit 21, that is, the image captured by the camera 11, the detection unit 23 detects specific actions performed by the worker during inspection. It is preferable that the specific operation is an operation that is repeatedly performed by the worker during inspection. Also, the specific operation is preferably an operation performed by a worker when inspecting various devices. As an example, the detection unit 23 detects a pointing and calling motion as the specific motion. Any image processing method may be used by the detection unit 23 to detect the pointing and calling motion.

In the information processing terminal 15, it is determined whether or not the detection unit 23 has detected a specific action, that is, a pointing and calling action (S105). When it is determined as Yes in S105, the identifying unit 24 identifies the work that the worker was doing when the image in which the detecting unit 23 detected the pointing and calling motion was captured (S106). The work content specified in S106 also includes the work content that the worker was going to do.

The identification unit 24 identifies the work content of the worker in S106 based on the signal acquired from the control device 6 during the specific period. The specific period is based on the time when the pointing and calling motion is performed, that is, when the camera 11 captures an image in which the detecting unit 23 detects the pointing and calling motion. As an example, the specific period is the period immediately before the pointing and calling motion is performed. The specific period may be a period including the time when the pointing and calling motion is performed. The specific period may be a period immediately after the pointing and calling action is performed.

For example, in a 2:1 roping elevator system, a suspension wheel is provided under the car 1. A rope 4 is wound around this hanging wheel. When inspecting the rotating state of the suspension wheel, the operator sets the operation mode to the pit-in mode. Therefore, if the ON signal indicating the pit-in mode is output during the specified period, the specifying unit 24 specifies operation inspection of the suspension wheel as the work content.

As another example, on top of the car 1, an operating device is provided for use by workers. A worker can move the car 1 at a low speed by operating this driving device. When checking the function of this operating device, the worker first assembles a safety fence on the car 1 . Next, the worker presses the travel button of the operating device, and then presses the up button and the down button in sequence. Therefore, if the switch signal for the safety fence and the ON signal for the travel button are output during the specific period, and the ON signal for the upper button and the ON signal for the lower button are output after that, the specifying unit 24 will Specify the function check of the operating device as the content.

When the work content is specified in S106, the creation unit 25 creates a work report (S107). At this time, the creating unit 25 uses the image captured by the camera 11 when the pointing and calling motion is performed as a reference image for the report item including the work content specified by the specifying unit 24 .

For example, let us consider a case where operation inspection of a hoisting wheel is specified as work content in S106 for the pointing and calling motion detected in S105. The work report includes a check box for indicating that a certain report item has been checked for operation of the hoisting wheel. Also, a space for attaching an image is provided adjacent to the check box. The creation unit 25 displays the image of the worker performing the pointing and calling motion, that is, the image in which the pointing and calling motion is detected by the detection unit 23 in S105, as an indication that the operation inspection of the suspension wheel has actually been performed. Attached to the space as a reference image for

At S108, it is determined whether or not the inspection by the worker has been completed. A series of processes from S101 to S107 are performed until the inspection is completed.

In the example shown in this embodiment, it is possible to create a work report using an image of a worker actually performing an inspection. Therefore, it is possible to provide the owner of the elevator device with a work report that looks good and is easy to read. For example, the owner can check the state of the worker actually performing the inspection on the car 1 from the work report. In addition, in the example shown in this embodiment, the worker does not need to operate the camera by himself in order to create a work report containing images. Therefore, the burden on workers can be reduced.

Other functions that can be adopted by the information processing terminal 15 will be described below. The information processing terminal 15 may employ a combination of the functions described below, if possible.

The detection unit 23 may detect the action of turning over a card as the specific action. In the inspection of elevator equipment, tags are used to prevent erroneous operation of specific switches or levers. For example, near the switch for shutting off the power of the control device 6, a tag indicating whether or not the operation is possible is hung. The worker turns over the card when operating the switch.

The detection unit 23 may detect other actions as specific actions. The detection unit 23 may detect a plurality of actions as specific actions. For example, the detection unit 23 may detect, as specific actions, a pointing and calling action and an action of turning over a card. In such a case, when the detecting unit 23 detects the pointing and calling motion, the determination in S105 is Yes. Also, when the detection unit 23 detects that the card is turned over, the determination in S105 is Yes.

The identification unit 24 may identify the work content of the worker in S106 based on a signal other than the signal from the control device 6. For example, a worker may check a specific piece of equipment before connecting the information processing terminal 15 to the control device 6 . In such a case, the information processing terminal 15 cannot acquire the signal from the control device 6 .

As an example, the information processing terminal 15 is provided with a microphone 26 . In such a case, the identification unit 24 identifies the work content of the worker in S106 based on the audio signal acquired by the microphone 26 . As a result, a work report can be created using the reference image even for work performed before the information processing terminal 15 is connected to the control device 6 . In this example, after the information processing terminal 15 is connected to the control device 6, the identification unit 24 identifies the work performed by the worker based on both the voice signal acquired by the microphone 26 and the signal from the control device 6. You can specify.

The work report created by the creation unit 25 is completed by the worker further inputting necessary items after the inspection is completed. A completed work report is displayed on the display 20 . The completed work report may be printed on paper. The completed work report may be saved as electronic data. When the work report is saved and viewed as electronic data, the creating unit 25 may use, as a reference image, a moving image captured by the camera 11 when the pointing and calling motion is performed.

In the present embodiment, an example has been described in which the information processing terminal 15 carried by maintenance personnel is a device for creating work reports regarding inspections. In this example, maintenance personnel can use the information processing terminal 15 at various sites.

As another example, the elevator device may be provided with a device having the same function as the information processing terminal 15 has. As an example, the device is permanently installed while being connected to the control device 6 . The control device 6 may be provided with the same functions as those of the information processing terminal 15 . As another example, the remote monitoring center 10 may be provided with functions similar to those of the information processing terminal 15 . In such a case, the communication device 8 transmits image data captured by the camera 11 to the monitoring center 10 via the network 9 .
