The hoisting machine 3 is connected via a signal line 11. In the elevator, camera fixing devices 12-1 to 12-3 for installing the camera device are installed. In the present embodiment, a camera fixer 12-1 is installed at the upper part of the ceiling surface of the car 6, and a camera fixer 12-2 is installed at the lower part of the floor of the car 6, and these camera fixers 12-1 are installed. And 12-2 are connected to the tail cord 9. A camera fixing device 12-3 is installed in a pit below the hoistway 2, and is connected to the elevator control device 8 </ b> A via the signal line 13. The elevator control device 8A is connected to a remote monitoring device 14 that performs monitoring control for inspection work via a network or the like.

  As shown in FIG. 2, the camera fixing devices 12-1 to 12-3 capture a predetermined monitoring target location regarding the inspection work of the elevator when the mobile terminal 121 having a camera function such as a smartphone is inserted. Thus, the portable terminal 121 is fixed, a built-in fixed switch (not shown) is switched to the ON state, and the portable terminal 121 is connected to a state in which communication is possible. When the mobile terminal 121 is removed, the fixed switch is switched to the OFF state. The camera fixing devices 12-1 to 12-3 transmit information indicating that the ON / OFF state of the fixed switch has been switched to the elevator control device 8A. Moreover, the camera fixing devices 12-1 to 12-3 acquire imaging information captured by the mobile terminal 121 that is fixed, and transmit it to the elevator control device 8A.

  As shown in FIG. 3, the elevator control device 8 </ b> A includes a switch information acquisition unit 81, an operation target device determination unit 82, an operation information acquisition unit 83, and a device control unit 84.

  The switch information acquisition unit 81 acquires the ON / OFF information of the fixed switch transmitted from the camera fixing devices 12-1 to 12-3. The operation target device determination unit 82 holds information on the operation target device set in advance for each camera fixing device at the time of inspection work, and the switch information acquisition unit 81 acquires the ON information of the fixed switch. When it is detected that the camera device is connected to one of the fixing devices, the operation target device corresponding to the camera fixing device is determined based on the held information on the operation target device. The operation information acquisition unit 83 acquires operation information for operating a predetermined device in the elevator regarding the inspection work, which is operated by the monitoring person in the monitoring control device 14. When the device corresponding to the operation information acquired by the operation information acquisition unit 83 corresponds to the operation target device determined by the operation target device determination unit 82, the device control unit 84 corresponds to the device based on the operation information. To work.

<Operation of Elevator System Using Elevator Control Device According to First Embodiment>
Next, the operation of the elevator system 1A according to the present embodiment will be described. In the present embodiment, the operation target device determination unit 82 of the elevator control device 8A of the elevator system 1A holds information on the hoisting machine 3 as an operation target device at the time of inspection work corresponding to the camera fixing device 12-1, and the camera is fixed. It is assumed that the operation target devices at the time of the inspection work corresponding to the containers 12-2 and 12-3 are not held.

  When the inspection switch is turned on by the inspection worker in the elevator system 1A in the state where the information is held in this way, the mode shifts to the inspection mode, and a landing button, a car button (not shown), etc. are operated. Shift to a state where no call is answered.

  Then, when an operator gets on the ceiling board of the car 6 and inserts the portable terminal 121 into the camera fixing device 12-1 to check the equipment above the hoistway 2, the portable terminal 121 is inserted by the camera fixing device 12-1. Is fixed and connected to a communicable state, and the fixed switch is switched to the ON state. Then, switch ON information indicating that the fixed switch has been switched to the ON state is transmitted from the camera fixing device 12-1 to the elevator control device 8A via the tail cord 9 and the connection box 10.

  The operation of the elevator control device 8A when switch ON information is acquired from the camera fixing device 12-1 will be described with reference to the flowchart of FIG.

  In the elevator control device 8A, the acquired switch ON information is acquired by the switch information acquisition unit 81, and the operation target device determination unit 82 detects that the portable terminal 121 is connected to the camera fixing device 12-1. The operation target device determination unit 82 further determines that the operation target device corresponding to the camera fixing device 12-1 is the hoisting machine 3 based on the held information on the operation target device (S1, S2).

  In a state where it is determined that the operation target device corresponding to the camera fixing device 12-1 is the hoisting machine 3, operation information for instructing raising / lowering of the car 6 for inspection work is transmitted from the monitoring control device 14 or the like. If the operation information is acquired by the operation information acquisition unit 83 (“YES” in S3), the operation information acquired by the operation information acquisition unit 83 corresponds to the operation target device determined by the operation target device determination unit 82. At some time (“YES” in S4), the operation of the corresponding device is controlled by the device control unit 84 based on the operation information (S5). For example, when the operation information “rising movement of the car 6” is acquired by the operation information acquisition unit 83, the device “winding machine 3” operating for this operation is determined by the operation target device determination unit 82. Since it corresponds to the target device “winding machine 3”, the operation of the winding machine 3 is controlled based on the operation information, and the car 6 moves up and down.

  In step S4, when the device corresponding to the operation information acquired by the operation information acquisition unit 83 does not correspond to the operation target device determined by the operation target device determination unit 82 ("NO" in S4), it is acquired. The operation of the device corresponding to the operation information is not performed (S6). For example, when the portable terminal 121 is fixed to the camera fixing device 12-2 or 12-3 that does not hold the operation target device, the operation information that instructs the elevator 6 to move up and down is acquired by the operation information acquisition unit 83. However, the car 6 does not move up and down.

  Further, when the portable terminal 121 is fixed to the camera fixing device 12-1, the portable terminal 121 causes the hoisting machine 3 or the like from the upper portion of the car 6 that is the monitoring target area set for the camera fixing device 12-1. Filming of the area up to the building ceiling begins. And the imaging information image | photographed with the portable terminal 121 is transmitted to 8 A of elevator control apparatuses.

  The imaging information acquired by the elevator control device 8A is transmitted to the remote monitoring device 14, and the imaging information is displayed by the remote monitoring device 14, so that the monitoring target area is visually monitored by a monitor.

  According to the first embodiment described above, only devices (such as a car) that are set as necessary for the location where the mobile terminal is fixed among the camera fixtures installed at a plurality of locations in the hoistway. By enabling operation, the car will not be raised or lowered even if the mobile terminal is fixed to the camera fixator in places where inspection work is performed without moving the car, such as in the pit, ensuring the safety of workers. Can do.

  In addition, by displaying on the remote monitoring control device 14 imaging information captured by the mobile terminal and acquired by the elevator control device 14, the monitoring target location is monitored not only by the control by the elevator control device but also by the eyes of the monitor. Can be further improved.

  In the present embodiment, the elevator control device 8B in the elevator system 1B includes an imaging information acquisition unit 85, an imaging information analysis unit 86, and an operation content determination in addition to the functional configuration of the elevator control device 8A, as shown in FIG. Part 87.

  The imaging information acquisition unit 85 acquires captured imaging information from the mobile terminal 121 connected to any of the camera fixing devices 12-1 to 12-3. The imaging information analysis unit 86 analyzes the imaging information acquired by the imaging information acquisition unit 85, and recognizes the distance between a predetermined monitoring target location and a worker, the moving speed of the car 6, and the like. Based on the information recognized by the imaging information analysis unit 86, the operation content determination unit 87 calculates a predicted distance between the monitoring target location and the worker after a predetermined time, and determines the operation content of the device corresponding to the predicted distance. judge. The device control unit 84 operates the corresponding device based on the content determined by the operation content determination unit 87.

<Operation of Elevator System Using Elevator Control Device According to Second Embodiment>
Next, operation | movement of the elevator system 1B by this embodiment is demonstrated. In the present embodiment, the operation content determination unit 87 of the elevator control device 8B also has an information table indicating the device operation content for ensuring the safety of the worker, which is set in advance for each distance between the monitoring target location and the worker. Is held. An example of an information table held in the operation content determination unit 87 is shown in FIG. The information table shown in FIG. 6 shows that the operation of the equipment when the distance between the monitoring target “building ceiling” and the worker is 1 m or less is “decelerate the moving speed of the car to 5 m / min and generate a warning sound. ”Report” is held, and “Forced stop of hoist” is held as the device operation content when the distance is 30 cm or less. In addition, as the equipment operation content when the distance between the monitoring target “winding machine” and the worker is 1 m or less, “decelerate the moving speed of the car to 5 m / min and issue a warning sound” is retained. Furthermore, “winding machine forced stop” is held as the device operation content when the distance is 30 cm or less. Also, there is no equipment operation content when the distance between the monitoring target “elevator part of the elevator control device” and the worker is 1 m or less, and the equipment operation content when the distance is 30 cm or less as well. “Warning sound alert” is held. In addition, “Slow down the moving speed of the car to 10 m / min and issue a warning sound” is retained as the equipment operation when the distance between the monitoring target “under the car” and the worker is 1 m or less. Furthermore, “winding machine forced stop” is held as the device operation content when the distance is 30 cm or less.

  With the information held in this way, the processing is executed as described in the first embodiment, and the operation of the elevator control device 8B that is executed when the imaging information by the portable terminal 121 is further acquired. This will be described with reference to the flowchart of FIG.

  In the elevator control device 8B, when reception of imaging information captured by the portable terminal 121 is started (“YES” in S11), the imaging information acquisition unit 85 acquires the imaging information. Then, the imaging information analysis unit 86 analyzes the imaging information at predetermined time intervals, and recognizes the distance between the predetermined monitoring target part and the worker, the moving speed of the car 6, and the like (S12).

  Next, based on the information recognized by the imaging information analysis unit 86, the operation content determination unit 87 calculates the predicted distance between the monitoring target location and the worker after a predetermined time, and the device corresponding to the predicted distance. The operation content is determined based on the information stored in the information table (S13). For example, the distance between the hoisting machine 3 and the worker on the car 6 and the moving speed of the car 6 are calculated based on the imaging information analyzed at predetermined time intervals, and the hoisting machine 3 after 5 seconds is calculated based on this. The predicted distance to the worker on the car 6 is calculated. When the calculated predicted distance becomes 1 m or less, based on the information table of FIG. 6, “the moving speed of the car 6 is reduced to 5 m / min and an alarm device (not shown) in the hoistway (not shown) or portable “Alarm sound is issued from terminal 121” is determined as the corresponding operation content. If the predicted distance further approaches 30 cm or less, “elevator forced stop” is determined as the corresponding operation content.

  Next, the operation of the device is controlled based on the content determined by the operation content determination unit 87 (S14). For example, control such as speed reduction of the car 6, alarming by an alarm device, forcibly stopping the elevator or the like is performed.

  According to the second embodiment described above, a dangerous situation after a predetermined time is predicted by analyzing the imaging information of the monitoring target image taken by the camera device fixed to the camera fixing device, and this is avoided in advance. Device operation can be performed.
