[0021] The embodiment of the present disclosure will be described with reference to the accompanying drawings. In the drawings, identical or corresponding parts are denoted by the same reference numerals, and any duplicate description of such parts will be simplified or omitted as appropriate.

[0022] Implementation method 1.

[0023] Figure 1 This is a schematic diagram of an elevator system to which the posture confirmation means in the first embodiment is applied.

[0024] Figure 1 An elevator system 1 is installed in a building 2. A hoistway 3 passes through each floor of the building 2. A machine room 4 is installed above the hoistway 3. A traction machine 5 is installed inside the machine room 4. A main rope 6 is wound around the traction machine 5.

[0025] The car 7 is installed inside the hoistway 3. The car 7 is suspended on one side of the main rope 6. The counterweight 8 is installed inside the hoistway 3. The counterweight 8 is suspended on the other side of the main rope 6.

[0026] The control panel 9 is installed in the machine room 4. The control panel 9 is provided so as to be able to control the elevator system 1 as a whole.

[0027] The control cable 10 is a cable for transmitting signals. The control cable 10 has a first surface 10a and a second surface 10b. The first surface 10a and the second surface 10b are flat surfaces. The second surface 10b faces in the opposite direction to the first surface 10a.

[0028] One end of the control cable 10 is connected to the control panel 9. The other end of the control cable 10 is connected to the car 7. In the control cable 10, the middle portion between the one end and the other end hangs down inside the hoistway 3. Specifically, one end of the control cable 10 extends downward from the control panel 9. The other end of the control cable 10 extends downward from the car 7. The middle portion extending from the other end of the control cable 10 is folded back below the car 7 in a manner that faces upward in the longitudinal direction. The middle portion of the control cable 10 extends upward from the folded portion toward one end. In this state, the first surface 10a of the control cable 10 is located on the inner peripheral side of the folded portion of the control cable 10. When the control cable 10 is in the reference posture, the portion of the first surface 10a that is closer to the control panel 9 side than the folded portion faces the center of the hoistway 3. The second surface 10b of the control cable 10 is located on the outer peripheral side of the folded portion of the control cable 10.

[0029] The posture confirmation system 20 monitors the posture of an object present inside the hoistway 3. The posture confirmation system 20 includes a lighting unit 21, a camera 22, a power cord 23, a portable terminal 24, a remote monitoring device 25, and a plurality of posture confirmation components 26.

[0030] The lighting unit 21 is provided at the lower portion of the car 7. The camera 22 is provided at the lower portion of the car 7. One end of a power cord 23 is mechanically and electrically connected to the camera 22. The other end of the power cord 23 is mechanically and electrically connected to the lighting unit 21.

[0031] For example, the portable terminal 24 is a smartphone capable of executing dedicated software. For example, the portable terminal 24 is carried by a maintenance person of the elevator system 1. The portable terminal 24 is provided so as to be able to communicate with the camera 22.

[0032] A remote monitoring device 25 is installed in the machine room 4. The remote monitoring device 25 is configured to obtain control information of the elevator system 1 from the control panel 9. The remote monitoring device 25 is electrically connected to the lighting unit 21 via a signal line bundled within the control cable 10. The remote monitoring device 25 is configured to communicate with the portable terminal 24.

[0033] Multiple position confirmation members 26 are attached to the control cable 10. These members 26 are components that allow visual confirmation of whether a portion of the control cable 10 has shifted from a normal position to a twisted position. For example, the members 26 are comprised of multiple first reflectors 27 and multiple second reflectors 28.

[0034] The first reflector 27 is composed of a first reflector 27a and a first mounting body 27b. The first reflector 27a has the property of reflecting light. For example, the first reflector 27a is a prismatic lens that retroreflects light. The first mounting body 27b is attached to the surface of the control cable 10. Specifically, for example, the first mounting body 27b is an adhesive.

[0035] A plurality of first reflectors 27 are attached to the first surface 10a of the control cable 10. The plurality of first reflectors 27 are arranged at predetermined intervals in the longitudinal direction of the control cable 10. The plurality of first reflectors 27 are provided on the first surface 10a in a portion extending from the folded portion of the control cable 10 toward the control panel 9 when the car 7 is in the lowest position. The plurality of first reflectors 27 are provided on the first surface 10a to the same height as the lower end of the car 7 when the car 7 is in the highest position.

[0036] The second reflector 28 is composed of a second reflector 28a and a second mounting body 28b. The second reflector 28a has a light-reflecting property. For example, the second reflector 28a is a prismatic lens that retroreflects light. The second reflector 28a is configured to be distinguishable from the first reflector 27a. For example, the color of the second reflector 28a is different from that of the first reflector 27a. The second mounting body 28b is attached to the surface of the control cable 10. Specifically, for example, the second mounting body 28b is an adhesive.

[0037] A plurality of second reflectors 28 are attached to the second surface 10b of the control cable 10. The plurality of second reflectors 28 are arranged at predetermined intervals in the longitudinal direction of the control cable 10. The plurality of second reflectors 28 are provided on the second surface 10b in a portion extending from the folded portion of the control cable 10 toward the control panel 9 when the car 7 is in the lowest position. The plurality of second reflectors 28 are provided on the second surface 10b to the same height as the lower end of the car 7 when the car 7 is in the highest position.

[0038] For example, in the elevator system 1, the control panel 9 receives car call registration information from the car 7 via the control cable 10. The control panel 9 rotates the hoisting machine 5. The main rope 6 moves in response to the rotation of the hoisting machine 5. The car 7 and the counterweight 8 rise and fall in opposite directions in response to the movement of the main rope 6. The other end of the control cable 10 moves vertically in response to the rise and fall of the car 7. The position of the return portion in the middle of the control cable 10 changes vertically in response to the movement of the other end of the control cable 10.

[0039] Maintenance personnel for the elevator system 1 perform an inspection operation on the portable terminal 24. In this case, the portable terminal 24 transmits an activation signal to the remote monitoring device 25. Based on the activation signal from the portable terminal 24, the remote monitoring device 25 supplies power to the lighting unit 21. The lighting unit 21 illuminates using a portion of this power. The lighting unit 21 supplies the remainder of this power to the camera 22 via the power line 23.

[0040] The lighting unit 21 is illuminated by receiving power. The camera 22 is supplied with power to capture images of the control cables 10 located below the car 7. For example, during normal operation, when the car 7 moves from the lowest position to the highest position, the camera 22 captures multiple images showing the control cables 10. Furthermore, during normal operation, when the car 7 moves from the highest position to the lowest position, the camera 22 captures multiple images showing the control cables 10.

[0041] When the control cable 10 is in a reference posture, which represents a normal state, the portion of the first surface 10a of the control cable 10 that is closer to the control panel 9 than the return portion faces the camera 22. In this state, the first reflector 27, which is attached to the portion of the control cable 10 that is closer to the control panel 9 than the return portion and is located below the car 7, appears within a predetermined range in the image captured by the camera 22. When the control cable 10 is in the reference posture, the second reflector 28, which is attached to the portion of the control cable 10 that is closer to the control panel 9 than the return portion, among the plurality of second reflectors 28, does not appear within a predetermined range in the image.

[0042] When the control cable 10 is in a first posture different from the reference posture, such as a twisted state, the portion of the first surface 10a that is closer to the control panel 9 than the return portion faces the side opposite to the camera 22. The portion of the second surface 10b that is closer to the control panel 9 than the return portion faces the camera 22. In this case, one or more of the plurality of first reflectors 27 attached to the portion of the control cable 10 that is closer to the control panel 9 than the return portion and located below the car 7 do not appear in the image. Furthermore, when the control cable 10 is in the first posture, one or more of the plurality of second reflectors 28 attached to the portion of the control cable 10 that is closer to the control panel 9 than the return portion appears in the image.

[0043] The camera 22 transmits information about the captured image via radio waves. The portable terminal 24 receives the radio waves representing the image information. The received image is displayed on the screen of the portable terminal 24. The maintenance personnel determines whether the control cable 10 is in the reference posture by visually confirming the image displayed on the portable terminal 24. For example, when the first reflector 27 appears within a specified range in the image, the maintenance personnel determines that the control cable 10 is in the reference posture. For example, when the second reflector 28 installed on the part closer to the control panel 9 than the folded part appears in the image, the maintenance personnel determines that the control cable 10 is in a posture different from the reference posture. In this case, the maintenance personnel performs the operation of checking the posture of the control cable 10.

[0044] Next, use Figure 2 and Figure 3 The lighting unit 21 and the camera 22 will be described.

[0045] Figure 2 This is a diagram showing an elevator car to which the posture confirmation system according to the first embodiment is applied, as viewed from below. Figure 3 This is a diagram showing the lighting and camera of the posture confirmation system in embodiment 1.

[0046] like Figure 2 As shown, the lighting unit 21 is provided below the car 7 to illuminate the lower portion of the car 7. The camera 22 is provided below the car 7 to capture the lower portion of the car 7 including the control cable 10.

[0047] like Figure 3 As shown, the lighting unit 21 includes a socket 29 , an adapter 30 , and a bulb 31 .

[0048] The socket 29 is fixed to the beam at the bottom of the car 7. Figure 3 The adapter 30 is electrically connected to the socket 29. The light bulb 31 is electrically connected to the adapter 30.

[0049] The other end of the power cord 23 has a plug 23a. The power cord 23 is mechanically and electrically connected to the adapter 30 via the plug 23a.

[0050] The adapter 30 distributes the power supplied to the socket 29 to the light bulb 31 and the camera 22 .

[0051] The camera 22 includes an antenna 32. The antenna 32 is provided so as to be able to transmit radio waves representing information of an image captured by the camera 22.

[0052] Next, use Figure 4 An example of an image captured by the camera 22 will be described.

[0053] Figure 4 This is a diagram showing an image showing the posture confirmation member and the control cables in the first embodiment.

[0054] exist Figure 4 In the figure, the range A surrounded by the dotted line is Figure 4 For example, the control cable 10 is set to be closer to the folded portion than the folded portion. Figure 4 The range where the portion on the control panel 9 side not shown exists is defined as the predetermined range.

[0055] The image of the second reflector 28 is located in the range B surrounded by the dotted line. Since the range B is not the range A surrounded by the dotted line, the maintenance personnel do not determine that the control cable 10 is in a posture different from the reference posture.

[0056] According to the first embodiment described above, the posture confirmation component 26 includes a first reflector 27a and a first mounting body 27b. The first reflector 27a reflects light. Therefore, the first reflector 27a can be easily visually identified in the image captured by the camera 22. In addition, the first mounting body 27b mounts the first reflector 27a at a position where it is captured by the camera 22 when the control cable 10 is in a reference posture, and is not captured by the camera 22 when the control cable 10 is in a first posture different from the reference posture. Therefore, in the image captured by the camera 22, it can be easily confirmed that the control cable 10 is in a posture different from the reference posture. In addition, the reference posture is the posture of the control cable 10 with the first surface 10a facing the camera 22. The first posture is the posture of the control cable 10 with the second surface 10b facing the camera 22.

[0057] Furthermore, the first reflector 27a may have a property that changes the color of reflected light depending on the angle of light reflection. The color of the image of the first reflector 27a in the image captured by the camera 22 changes depending on the position of the middle portion of the control cable 10. In this case, maintenance personnel can determine the position of the control cable 10 based on the color of the image of the first reflector 27a when the control cable 10 is in the reference position. This makes it easier to confirm the position of the control cable 10.

[0058] The posture confirmation component 26 also includes a second reflector 28a and a second mounting body 28b. The second reflector 28a reflects light. Therefore, when the control cable 10 is in a posture different from the reference posture, the operator can easily visually identify the image of the second reflector 28a in the image captured by the camera 22. Furthermore, the second mounting body 28b is mounted in a position where the second reflector 28a is not visible to the camera 22 when the control cable 10 is in the reference posture, but is visible to the camera 22 when the control cable 10 is in a posture different from the reference posture. This makes it easy to confirm the posture of the control cable 10.

[0059] In addition, the plurality of first mounting bodies 27b attach the plurality of first reflectors 27a to positions on the first surface 10a of the control cable 10 that can be captured by the camera 22 during the period from when the car 7 is at its lowest position to when the car 7 is at its highest position. Therefore, the posture of the control cable 10 can be confirmed throughout substantially the entire interior of the hoistway 3.

[0060] Furthermore, according to the posture confirmation system 20 of embodiment 1, the camera 22 photographs the control cable 10 when the elevator system 1 is in normal operation. At this time, the control cable 10 moves at the same speed as in normal automatic operation. Therefore, the posture confirmation system 20 can confirm the dynamic characteristics of the movement of the control cable 10 in normal automatic operation. In addition, the dynamic characteristics of the control cable 10 are sometimes visually confirmed by maintenance personnel located at the lower part of the hoistway 3. In this case, the car 7 moves by manual operation which is slower than the automatic operation. The dynamic characteristics of the control cable 10 are confirmed only under the condition that the car 7 moves upward by manual operation. According to the posture confirmation system 20 of embodiment 1, the dynamic characteristics of the control cable 13 under the condition that the car 7 is raised and lowered at the speed of automatic operation can be confirmed.

[0061] Furthermore, the camera 22 may transmit information of a moving image as a continuous image to the portable terminal 24 .

[0062] Furthermore, the camera 22 may be a camera provided to capture images of equipment other than the interior of the hoistway 3 for controlling the cables 10. Therefore, the posture confirmation system 20 can be configured at low cost.

[0063] In addition, the second reflector 28a may be provided so as to be distinguishable from the first reflector 27a in terms of shape.

[0064] Furthermore, the first attachment body 27 b and the second attachment body 28 b may not be adhesives but may be members such as tapes and fittings that can attach the first reflector 27 a or the second reflector 28 a to the control cable 10 .

[0065] Implementation method 2.

[0066] Figure 5 1 is a diagram showing an overview of a posture confirmation system in Embodiment 2. Components identical or corresponding to those in Embodiment 1 are denoted by the same reference numerals, and descriptions of such components are omitted.

[0067] like Figure 5 As shown, in the second embodiment, the posture confirmation system 20 further includes an analyzing device 40 .

[0068] The analyzing device 40 is installed in a building different from the building 2. For example, the analyzing device 40 is installed in an information center of a company that maintains and manages the elevator system 1. The analyzing device 40 is provided so as to be communicable with the remote monitoring device 25 via a monitoring line.

[0069] The analyzing device 40 determines whether the control cable 10 is in the reference posture based on a comparison image obtained by the camera 22 capturing the control cable 10 and the plurality of posture confirmation components 26. Specifically, the analyzing device 40 determines whether the control cable 10 is in the reference posture by detecting a difference between the reference image and the comparison image of the control cable 10 and the plurality of posture confirmation components 26 exhibiting the reference posture. For example, if the analyzing device 40 detects a difference between the position of the image of the second reflector 28 in the reference image and the comparison image, the analyzing device 40 determines that the control cable 10 is not in the reference posture.

[0070] In the second embodiment, the remote monitoring device 25 is provided so as to be able to receive image information from the camera 22 .

[0071] The remote monitoring device 25 causes the camera 22 to capture images of the control cables 10 at a predetermined interval. For example, when the elevator system 1 is in normal operation, the remote monitoring device 25 supplies power to the lighting unit 21 and the camera 22. While the car 7 moves from the lower portion to the upper portion of the hoistway 3, the camera 22 captures images of the control cables 10. The camera 22 transmits information on the captured images to the remote monitoring device 25.

[0072] The remote monitoring device 25 stores the image information received from the camera 22. The remote monitoring device 25 periodically transmits the image information received from the camera 22 to the analysis device 40. Based on the received image information, the analysis device 40 determines whether the control cable 10 is in the reference posture. For example, if the control cable 10 is determined not to be in the reference posture, a maintenance worker from the maintenance company dispatches maintenance personnel to the building 2.

[0073] According to the second embodiment described above, the posture confirmation system 20 includes a camera 22, a first reflector 27a, a first mounting body 27b, and an analyzer 40. The analyzer 40 determines whether the control cable 10 is in a posture different from a reference posture based on information from the image captured by the camera 22. Because the first reflector 27a and the first mounting body 27b are provided on the control cable 10, the analyzer 40 can easily confirm the posture of the control cable 10. As a result, the posture of the control cable 10 can be monitored.

[0074] Furthermore, the analyzing device 40 may determine that the control cable 10 is not in the reference posture when detecting that the image of the second reflector 28 exists within a predetermined range in the comparison image.

[0075] Furthermore, the analyzing device 40 may determine whether the control cable 10 is in a first posture different from a reference posture.

[0076] Alternatively, the remote monitoring device 25 may combine multiple images captured by the camera 22 to store information showing a panoramic image from the bottom to the top of the shaft 3. In this case, the analyzing device 40 may also determine that the control cable 10 is not in the reference posture based on the information of the panoramic image.

[0077] Next, use Figure 6 An example of hardware constituting the analysis device 40 will be described.

[0078] Figure 6 This is a hardware configuration diagram of the analysis device of the posture confirmation system in the second embodiment.

[0079] Each function of the analysis device 40 can be implemented by a processing circuit. For example, the processing circuit includes at least one processor 100a and at least one memory 100b. For example, the processing circuit includes at least one dedicated hardware 200.

[0080] When the processing circuit includes at least one processor 100a and at least one memory 100b, the various functions of the analysis device 40 are implemented using software, firmware, or a combination of software and firmware. At least one of the software and firmware is described as a program. At least one of the software and firmware is stored in the at least one memory 100b. The at least one processor 100a implements the various functions of the analysis device 40 by reading and executing the program stored in the at least one memory 100b. The at least one processor 100a is also referred to as a central processing unit, processing unit, computing unit, microprocessor, microcomputer, or DSP. For example, the at least one memory 100b may be a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM, or a magnetic disk, floppy disk, optical disk, CD, minidisc, or DVD.

[0081] When the processing circuit includes at least one dedicated hardware 200, the processing circuit may be implemented, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the analysis device 40 may be implemented separately by the processing circuit. For example, each function of the analysis device 40 may be implemented collectively by the processing circuit.

[0082] The various functions of the analysis device 40 may be partially implemented by dedicated hardware 200, and the remaining functions may be implemented by software or firmware. For example, the function of receiving information from the remote monitoring device 25 may be implemented by the processing circuit of the dedicated hardware 200, while the functions other than the function of receiving information from the remote monitoring device 25 may be implemented by the at least one processor 100a reading and executing a program stored in the at least one memory 100b.

[0083] In this manner, the processing circuit implements the various functions of the analysis device 40 through hardware 200, software, firmware, or a combination thereof.
