no. 1 Embodiment approach

[0023] figure 1 It is a diagram schematically showing an elevator to which the tail cable damage detection device according to the first embodiment of the present invention is applied. exist figure 1 Among them, the symbol 10 represents the hoistway of the elevator, and the symbol 14 represents the car. 12 represents a control panel. The control panel 12 is connected to the car 14 through a tail cable 16 . The tail cable 16 is a U-shaped curved portion that hangs down largely to follow the lift of the car 14 . In addition, depending on the elevator, some tail cables 16 are connected to the relay board, but even if the relay board is used instead of the control board 12, the present invention can be applied similarly.

[0024] Electric power is supplied to the car 14 via the tail cable 16 , and signals are transmitted and received between the car 14 and the control panel 12 via the tail cable 16 . The tail cable 16 is a bundle of power lines and signal lines, and the outsi...

no. 2 Embodiment approach

[0050] Next, refer to Figure 7 A breakage detection device for a tail cable according to a second embodiment of the present invention will be described.

[0051] This second embodiment is an embodiment in which a camera 20 is installed on a tail cable 16 using a camera movable stand as follows.

[0052] This camera movable stand is installed on the U-shaped bend of the tail cable 16 . The camera movable stand has a bracket 30 on which the camera 20 is attached in an upward posture, and a roller 32 supported on a shaft 31 and rotating along the tail cable 16 .

[0053] According to the second embodiment as above, the camera movable base moves along the U-shaped bend of the tail cable 16 as the car 10 ascends and descends, but the camera 20 is always at a position close to the covering surface of the tail cable 16 . That is, the sheathed surface of the tail cable 16 flows in front of the camera 20 . Thereby, the camera 20 can photograph the entire range where there is a poss...

no. 3 Embodiment approach

[0055] then, Figure 8 It is a block configuration diagram showing a damage detection device for a pigtail cable according to a third embodiment of the present invention.

[0056] This third embodiment is an embodiment in which a 3D scanner 35 is used together with a camera 20 . The 3D scanner 35 projects laser light onto the cladding surface of the pigtail cable 16, and three-dimensionally reproduces the shape of the surface from the reflected laser light.

Abstract

The invention relates to a damage detection method and device for a tail cable and an elevator control system. Whether the tail cable is damaged or not can be easily found before damage becomes large.The damage detection device for a tail cable according to an embodiment of the present invention is provided with: a camera (20) that is disposed at a position within a lift path (10), said positionbeing capable of capturing an image of a damaged portion of the tail cable (16), and that captures an image of the surface of the tail cable (16); and an image processing device for analyzing the image data acquired from the camera (20) and extracting a damaged region present on the surface of the tail cable (16).

Description

technical field [0001] Embodiments of the present invention relate to a damage detection method and device for a tail code. Background technique [0002] A tail cable is connected to the elevator car, and the tail cable is formed by bundling electric wires such as a power line for supplying electric power and a signal line for exchanging signals with a control panel. The tail cable hangs down from the car and moves up and down following the lift of the car. [0003] A net using a metal net or the like is installed along the wall surface of the liftway. By laying this net (net), the tail cable is not caught on the hoistway. [0004] The tail cable often swings with the movement of the car. At this time, when the tail cable is in contact with the net and repeated many times, the tail cable will sometimes be injured, and in the worst case, it will sometimes cause a disconnection. [0005] Conventionally, various countermeasures have been taken against such swinging of the t...
