[0012] Hereinafter, the present embodiment will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and description thereof will not be repeated.

[0013] [Embodiment Mode] <Overall structure> 1 is a diagram showing an example of the overall configuration of an elevator system and an elevator remote inspection system. In the following embodiment, an "elevator inspection system" according to the present disclosure is incorporated into elevator system 1. However, the "elevator inspection system" according to the present disclosure may be manufactured, sold, etc. separately from elevator system 1.

[0014] The elevator system 1 includes a control panel 10 and an elevator equipment group 20. The control panel 10 controls various devices included in the elevator equipment group 20. The elevator equipment group 20 includes one or more elevators, a plurality of hall devices, etc. The configuration of the elevator system 1 will be described in detail later with reference to Figs. 2 to 4.

[0015] In this embodiment, it is assumed that the elevator system 1 is installed in a building (BLDG). In this case, the building owner concludes a maintenance contract with an elevator maintenance company that operates the elevator remote inspection system 3. Maintenance personnel belonging to the elevator maintenance company perform inspection work (maintenance inspection and periodic inspection) of the elevator system 1 based on the concluded maintenance contract. The maintenance contract may optionally include remote monitoring or remote inspection.

[0016] Remote monitoring refers to the elevator remote inspection system 3 constantly monitoring for any abnormalities (malfunctions) in the elevator using a communication line. Remote inspection refers to the elevator remote inspection system 3 not only remote monitoring but also using a communication line to inspect whether the elevator's operating status and the operating status of each device are normal, targeting areas required for normal elevator operation.

[0017] Remote inspections include three types of inspections: elevator performance inspections, equipment inspections, and usage status inspections. Performance inspections cover inspection items such as the car's startup status, acceleration / travel status, constant speed running status, deceleration running status, and floor arrival status. Equipment inspections cover inspection items such as the temperature of the machine room or control panel, the status of the control equipment, the status of the destination floor buttons in the car, the status of the intercom, the status of the doors opening and closing, the status of the landing buttons, the status of the door switches, and whether there are any abnormalities in the electromagnetic brakes. Usage status inspections cover inspection items such as the car's travel distance, travel time or number of starts, and the number of times the doors have opened and closed.

[0018] By implementing such remote inspections, the amount of on-site inspection work can be reduced, greatly improving the efficiency of maintenance work. In addition, there are legal provisions that allow the implementation of remote inspections to extend the interval between statutory periodic inspections, further improving the efficiency of maintenance work. For example, in Japan, by implementing the remote inspections listed above, the legally mandated interval for periodic inspections can be reduced from once a month to once every three months.

[0019] The elevator remote inspection system 3 includes, for example, a remote inspection device 31, a management server 32, and a plurality of terminals 33. The remote inspection device 31, the management server 32, and the plurality of terminals 33 are connected to each other via a communication line so as to be able to communicate with each other.

[0020] The remote inspection device 31 is installed in the building BLDG together with the elevator system 1. The remote inspection device 31 is communicatively connected to the elevator system 1 and performs remote inspection of the elevator system 1. The remote inspection device 31 is implemented using, for example, a PLC (Programmable Logic Controller).

[0021] Management server 32 is installed, for example, in a central monitoring center CMC of an elevator maintenance company. Management server 32 manages remote inspection device 31. More specifically, management server 32 sends commands to remote inspection device 31 to execute remote inspections, and acquires the results of remote inspections executed by remote inspection device 31. Management server 32 also manages various data such as customer information for many buildings with which elevator maintenance contracts have been concluded, information on each building, information on the elevator systems installed in each building, and remote inspection results.

[0022] In this example, each of the multiple terminals 33 is installed in the central monitoring center CMC. However, each terminal 33 may be installed in any location. The terminal 33 is, for example, a personal computer (PC), a smartphone, or a tablet. In this embodiment, the terminal 33 is used by a maintenance worker of an elevator maintenance company. The terminal 33 is configured to cause the remote inspection device 31 to perform a remote inspection via the management server 32 in accordance with the maintenance worker's operation on an input unit (not shown). The terminal 33 is also configured to display the results of the remote inspection performed by the remote inspection device 31 on a display unit (not shown). However, the user of the terminal 33 is not limited to a maintenance worker, and may be an employee other than the maintenance worker of the elevator maintenance company, or the manager of the building BLDG.

[0023] <Elevator system configuration> 2 is a diagram showing an example of the hardware configuration of the elevator system 1. The control panel 10 includes a car control unit 11. The car control unit 11 includes a control board that controls the elevator equipment group 20. The control board includes a processor 111, a memory 112, and an interface 113. The components of the car control unit 11 are connected via a bus. The control panel 10 corresponds to the "diagnostic device" according to the present disclosure.

[0024] The processor 111 is an arithmetic processing device such as a CPU (Central Processing Unit) or an MPU (Micro-Processing Unit). The memory 112 may include volatile memory such as RAM (Random Access Memory) and rewritable non-volatile memory such as an SSD (Solid State Drive) or flash memory. The memory 112 stores system programs including an OS (Operating System) and control programs including computer-readable code required for arithmetic processing. The processor 111 performs various processes by reading the system programs and control programs and expanding them in the memory 112. While FIG. 2 shows an example in which the each-machine control unit 11 includes one processor 111, the each-machine control unit 11 may include multiple processors. The same applies to the memory 112.

[0025] In this specification, the term "processor" is not limited to a processor in the narrow sense that executes processing using a stored program, but may also include hardwired circuits such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). Therefore, the term "processor" can also be interpreted as a processing circuitry whose processing is predefined by computer-readable code and / or hardwired circuitry.

[0026] Each car control unit 11 is connected via an interface 113 to various devices in the elevator device group 20 and a remote inspection device 31 (see FIG. 1) so as to be able to communicate with each other.

[0027] In this embodiment, it is assumed that the building BLDG in which the elevator system 1 is installed has five floors. For simplicity, it is also assumed that only one elevator is installed in the building BLDG. This elevator will be referred to as "No. 1 EV1." No. 1 EV1 is a traction elevator. A traction elevator is one type of rope elevator.

[0028] The elevator equipment group 20 includes a car 21 of the first elevator EV1, a counterweight (balancing weight) 22, a hoist 23, a deflector 24 and a rope 25, hall devices 261 to 265 installed at the halls of each floor from the first to fifth floors, sensors and switches 27, and a camera 28 installed on the first elevator EV1.

[0029] The configuration of the first EV1 will be explained in Figure 3 onwards. The individual vehicle control unit 11 is connected to the car 21 of the first EV1 and the like via a control cable 291. The individual vehicle control unit 11 is also connected to the hall devices 261-265 on each floor and the sensors and switches 27 via a control cable 292. The individual vehicle control unit 11 is connected to the camera 28 via a control cable 293.

[0030] 3 is a diagram showing the structure of the elevator (No. 1 EV1) in which the Z axis represents the vertical upward direction.

[0031] The car 21 of the first EV1 is installed inside the elevator shaft 4 provided in the building BLDG. The car 21 moves up and down inside the elevator shaft 4 to move between the first floor and the fifth floor. The car 21 can stop at each floor.

[0032] A machine room 41 is provided directly above the hoistway 4. In the machine room 41, the hoisting machine 23, the deflector wheel 24, the camera 28, the control panel 10, and the remote inspection device 31 are arranged.

[0033] A pit 42 is provided directly below the elevator shaft 4. A shock absorber (buffer) 421 is installed in the pit 42 to absorb the impact when the car 21 falls due to the occurrence of an abnormality.

[0034] Rope 25 has both ends (first end and second end) from which car 21 and counterweight 22 are suspended. The first end of rope 25 passes through a passage hole 51 provided in hoistway 4 and is connected to car 21. The second end of rope 25 passes through another passage hole 52 provided in hoistway 4 and is connected to counterweight 22. Inspection jigs 61 and 62 (details will be described later) for inspecting whether rope 25 is in contact or not are provided in passage holes 51 and 52, respectively.

[0035] The rope 25 is hung on the hoist 23 and the deflector sheave 24. The hoist 23 is provided with an anti-sway member 71 to prevent the rope 25 from coming off the hoist 23. The deflector sheave 24 is also provided with an anti-sway member 72 for the rope 25. The anti-sway members 71 and 72 are typically angle anti-sway fittings. The anti-sway members 71 and 72 are also provided with inspection jigs 81 and 82, respectively, to check whether the rope 25 is in contact with them.

[0036] An inspection jig may be provided on only one of the anti-sway member 71 of the hoist 23 and the anti-sway member 72 of the deflection sheave 24. The hoist 23 and the deflection sheave 24 correspond to the "hoisting device" according to the present disclosure. The "hoisting device" according to the present disclosure may include the hoist 23 but may not include the deflection sheave 24.

[0037] The camera 28 is a camera capable of capturing color images, and is configured to capture images of the rope 25 while the car 21 is moving. The camera 28 outputs the captured images to the control panel 10.

[0038] It is not necessary to provide the machine room 41. In that case, the hoist 23, deflector 24, camera 28, control panel 10, etc. may be disposed in other locations (such as the wall of the elevator shaft 4 or inside the pit 42).

[0039] Furthermore, the elevator is not limited to the traction elevator described above, in which the car 21 and the counterweight 22 are balanced. The elevator may be, for example, a drum elevator, in which the car is raised and lowered by winding a rope around a drum, without using a counterweight. A drum elevator is another form of a rope elevator.

[0040] <Elevator inspection jig> Fig. 4 is a diagram showing an example of the configuration of the inspection jig 61. Fig. 4 shows a top view of the inspection jig 61 viewed vertically from above to below.

[0041] In this example, the passage hole 51 for the rope 25 has a square shape. However, the shape of the passage hole 51 is not limited to this and may be other shapes (rectangle, circle, etc.). The inspection jig 61 has a square shape similar to the passage hole 51 when viewed from above, and is arranged around the passage hole 51. The inspection jig 61 includes a coloring member 610 configured to color the rope 25 when the rope 25 comes into contact with it. In this example, the coloring member 610 is provided around the entire circumference of the passage hole 51. The coloring member 610 may be, for example, a powder or solid paint (such as chalk). The coloring member 610 may be, for example, a liquid or paste paint (such as fluorescent paint).

[0042] The colored member 610 does not have to be provided around the entire circumference of the passage hole 51. For example, if there is a high possibility that the rope 25 will come into contact with the passage hole 51 on one specific side of the four sides of the passage hole 51, the colored member 610 may be provided only on that side. The colored member 610 may also be provided on only two or three sides. In other words, it is sufficient that the colored member 610 is provided on at least a portion of the periphery of the passage hole 51.

[0043] The configuration of inspection jig 62 is the same as the configuration of inspection jig 61, and therefore description thereof will not be repeated. Although not shown, inspection jig 81 provided on anti-sway member 71 of hoisting machine 23 also includes a coloring member configured to color rope 25 when rope 25 comes into contact with it. The same is true for inspection jig 82 provided on anti-sway member 72 of deflector sheave 24.

[0044] In this embodiment, four inspection jigs 61, 62, 81, and 82 are arranged on the first unit EV1. By arranging multiple inspection jigs in this manner, it is possible to inspect the contact of rope 25 at multiple locations at once. However, only one to three of the four inspection jigs 61, 62, 81, and 82 may be arranged. For example, the inspection jigs may be arranged only on the passage holes 51 and 52 for rope 25, or only on the anti-vibration members 71 and 72.

[0045] The colored members of inspection jigs 61, 62 placed in passage holes 51, 52 of rope 25 correspond to the "first colored member" according to the present disclosure. The colored members of inspection jigs 81, 82 placed in anti-vibration members 71, 72 correspond to the "second colored member" according to the present disclosure. Only one of inspection jigs 61, 62 and inspection jigs 81, 82 may be provided.

[0046] <Processing flow> <Example 1> Fig. 5 is a flowchart showing a first example of the processing procedure of an elevator inspection method. The processing shown in this flowchart is called from a main routine (not shown) and executed when a predetermined condition is met (for example, at predetermined intervals). Each step is realized by software processing by the control panel 10 (the processor 111 in the individual elevator control unit 11 shown in Fig. 2), but may also be realized by hardware (electrical circuitry) arranged in the control panel 10. The same applies to the processing shown in other flowcharts described later. Hereinafter, steps are abbreviated as S.

[0047] 3 and 5, in S101, the control panel 10 determines whether or not a diagnostic operation command for the first elevator EV1 has been received from the elevator remote inspection system 3 (remote inspection device 31). Diagnostic operation is performed periodically (for example, once a month) during a time period when there are no passengers using the first elevator EV1 (such as late at night). If a diagnostic operation command has not been received (NO in S101), the control panel 10 returns the process to the main routine without performing any further contact diagnosis of the rope 25. However, the timing of the diagnosis is not limited to during diagnostic operation. A diagnosis (continuous diagnosis) may be performed every time the car 21 is operated by an elevator passenger or the like.

[0048] When a diagnostic operation command is received (YES in S101), the control panel 10 controls the camera 28 to start photographing the rope 25 (S102). Subsequently, the control panel 10 controls the hoist 23 to start the diagnostic operation (S103). When the diagnostic operation is performed, the first unit EV1 moves from the first floor to the fifth floor at a slower speed than during normal operation. When the first unit EV1 reaches the fifth floor, the control panel 10 controls the hoist 23 to end the diagnostic operation (S104). Thereafter, the control panel 10 controls the camera 28 to end photographing the rope 25 (S105). As a result, the rope 25 is photographed along its entire length.

[0049] In S106, the control panel 10 determines whether or not coloring of the rope 25 by the colored member 610 is detected (observed) based on the video (moving image or still images taken at regular time intervals) captured by the camera 28.

[0050] If coloring of the rope 25 is detected (YES in S106), the control panel 10 records the diagnosis result that the rope 25 has come into contact with any of the four inspection jigs 61, 62, 81, and 82 (S107). Then, the control panel 10 transmits the diagnosis result to the remote inspection device 31 (S108). As a result, the diagnosis result that the rope 25 has come into contact (modulation has been detected) is transmitted from the remote inspection device 31 to the management server 32 and / or the terminal 33 (see FIG. 1).

[0051] On the other hand, if no coloring of the rope 25 is detected (NO in S106), the control panel 10 records the diagnosis result that the rope 25 has not come into contact with any of the four inspection jigs 61, 62, 81, and 82 (S109). Then, the control panel 10 transmits the diagnosis result to the remote inspection device 31 (S110). As a result, the diagnosis result that the rope 25 has not come into contact (modulation not detected) is transmitted from the remote inspection device 31 to the management server 32 and / or the terminal 33.

[0052] <Example 2> In the second example, it is assumed that only one of the four inspection jigs 61, 62, 81, and 82 (hereinafter, only the inspection jig 61) is placed.

[0053] 6 is a flowchart showing a second example of the procedure of the elevator inspection method. This flowchart differs from the flowchart in the first example (see FIG. 5) in that it further includes the process of S208.

[0054] 3 and 6, if coloring of rope 25 is detected (YES in S206), control panel 10 records the diagnosis result that rope 25 has come into contact with inspection jig 61 (S207).

[0055] In S208, the control panel 10 calculates and records the position of the car 21 corresponding to the colored portion of the rope 25. For example, the control panel 10 calculates the time difference from when the movement of the rope 25 starts during diagnostic operation until the coloring of the rope 25 is detected by analyzing the video captured by the camera 28. The movement speed (speed profile) of the car 21 during diagnostic operation is known to the control panel 10. Therefore, the control panel 10 can calculate how far the car 21 has moved from its initial position (the first floor in this example) during the time difference. Therefore, the control panel 10 can calculate, from the colored portion of the rope 25, the position of the car 21 at the time the rope 25 came into contact with the passage hole 51.

[0056] In S209, the control panel 10 adds the position information of the car 21 at the time when the rope 25 came into contact with the passage hole 51 to the diagnosis result that there is contact with the rope 25, and transmits this to the remote inspection device 31. Then, the diagnosis result that there is contact and the additional information on the car position are sent from the remote inspection device 31 to the management server 32 and / or the terminal 33 (see FIG. 1).

[0057] When a maintenance person from an elevator maintenance company visits the site for a detailed visual inspection, the maintenance person sets the position of car 21 so that car 21 moves to the position indicated in the additional information. This allows the maintenance person to easily observe the contact state between rope 25 and passage hole 51.

[0058] Other processes in the second example are similar to the corresponding processes in the first example, and therefore detailed description will not be repeated.

[0059] <Example 3> In the third example, it is assumed that four inspection jigs 61, 62, 81, and 82 are arranged, and the colors of the colored members (for example, the colors of chalk) are different between these inspection jigs.

[0060] 7 is a flowchart showing a third example of the procedure of the elevator inspection method. This flowchart differs from the flowchart in the first example (see FIG. 5) in that it further includes the processes of S308 and S309.

[0061] 3 and 7, if coloring of rope 25 is detected (YES in S306), control panel 10 records a diagnosis result that contact has occurred with any of four inspection jigs 61, 62, 81, 82 (S307).

[0062] In S308, the control panel 10 identifies, from the color of the rope 25, which of the four inspection jigs 61, 62, 81, and 82 the rope 25 has come into contact with.

[0063] In S309, the control panel 10 calculates and records the position of the car 21 corresponding to the colored portion of the rope 25. This process is basically the same as the process of S208 in the second example. The control panel 10 may perform the same process as the process of S208 for the inspection jig identified in S308.

[0064] In S310, the control panel 10 adds information indicating the contact point of the rope 25 (information indicating which inspection jig contacted the rope 25) and the position information of the car 21 at the time of contact with the rope 25 to the diagnosis result that there is contact, and transmits this to the remote inspection device 31. Then, the diagnosis result that there is contact and the additional information regarding the contact point and the car position are sent from the remote inspection device 31 to the management server 32 and / or terminal 33 (see FIG. 1).

[0065] When a maintenance person from an elevator maintenance company visits the site for a detailed visual inspection, the person sets the position of car 21 so that car 21 moves to the position indicated in the additional information. The color of rope 25 also identifies which of rope 25 passage holes 51, 52 and anti-sway members 71, 72 has come into contact with rope 25. This allows the maintenance person to easily observe the state of contact between the identified location and rope 25.

[0066] 8 is a diagram showing another example of the configuration of the inspection jig. Inspection jig 61A may be configured to color rope 25 different colors depending on the contact position with rope 25. Inspection jig 61A includes, for example, four colored portions 611 to 614. Colored portions 611 to 614 are provided on corresponding sides of the four sides of square passage hole 51. Colors of colored portions 611 to 614 are different from one another. These four colors are preferably different from the colors used by the other three inspection jigs 62, 81, and 82.

[0067] In this way, by employing the colored portions 611 to 614 that are colored in different colors, it is possible to identify in more detail which of the four sides of the passage hole 51 (inspection jig 61A) the rope 25 has come into contact with. Therefore, the maintenance personnel can focus on observing the contact state between the identified side and the rope 25.

[0068] As described above, in this embodiment, inspection jigs 61, 62, 81, 82 including colored members are respectively disposed in some or all of the passage holes 51, 52 for rope 25, the anti-sway member 71 of hoisting machine 23, and the anti-sway member 72 of deflector sheave 24. By using camera 28 to detect that rope 25 has come into contact with one of the four inspection jigs 61, 62, 81, 82 and become colored, maintenance personnel from an elevator maintenance company do not need to visually check rope 25. Therefore, this embodiment can reduce the labor required for elevator inspection work.

[0069] As mentioned above, only one of the four inspection jigs 61, 62, 81, and 82 may be installed. If even one of the inspection jigs is installed, the first unit EV1 can be moved from the first floor to the fifth floor through diagnostic operation to photograph the entire length of the rope 25. Therefore, the entire rope 25 can be diagnosed with a small number of inspection jigs. On the other hand, if all four inspection jigs 61, 62, 81, and 82 are installed, the presence or absence of contact of the rope 25 with the rope 25 passage holes 51 and 52, the hoist 23, and the deflector sheave 24 can be diagnosed in a single diagnostic operation.
