[0008] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions in order to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, some of the components may be omitted in order to facilitate understanding.

[0009] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] Hereinafter, an embodiment of an elevator inspection system and an inspection device will be described with reference to Figures 1 to 9. Note that the following embodiment is provided as an example to aid in understanding the configuration of the elevator inspection system and the inspection device, and is not intended to limit the configuration of the elevator inspection system and the inspection device.

[0011] As shown in Figures 1 and 2, an elevator inspection system (hereinafter also simply referred to as an "inspection system") 1 may include, for example, an elevator 2, a rope tester 3 and an inspection device 4 for inspecting a rope 2a of the elevator 2, and a memory device 5 for storing data.

[0012] The elevator 2, the rope tester 3, the inspection device 4, and the storage device 5 may be able to communicate with each other, for example, by a communication means 6. Although not particularly limited, the communication means 6 may be a wired communication means such as a wired LAN or a communication cable, or may be a wireless communication means such as the Internet, Bluetooth (registered trademark), or a wireless LAN.

[0013] The storage device 5 may be, for example, a server, etc. Although not particularly limited, the owner of the storage device 5 may be the same as or different from the owners of the elevator 2, the rope tester 3, and the inspection device 4, for example.

[0014] The elevator 2 may, for example, as in this embodiment, be equipped with a car 2b and a counterweight 2c each connected to a rope 2a, a hoist 2d that drives the rope 2a to move the car 2b and the counterweight 2c in an upward and downward direction, a car rail 2e that guides the car 2b, a counterweight rail 2f that guides the counterweight 2c, an input device 2g to which data is input, a processing device 2h that processes the data, and an output device 2i that outputs the data.

[0015] In addition, the elevator 2 according to this embodiment is configured such that the hoisting machine 2d is disposed inside the machine room X2, but is not limited to such a configuration. For example, the elevator 2 may be configured such that the machine room X2 is not provided and the hoisting machine 2d is disposed inside the hoistway X1.

[0016] The input device 2g may include, for example, a car operating panel arranged in the car 2b, a hall operating panel arranged in the hall X3, an inspector operating unit arranged in the car 2b (for example, on the top or inside) or in the machine room X2, etc., which are not shown in the figure. The output device 2i may include, for example, a car output unit arranged in the car 2b, a hall output unit arranged in the hall X3, etc., which are not shown in the figure.

[0017] For example, the processing device 2h may control the hoist 2d based on data input to the input device 2g during normal operation (for example, destination floor data input to a car operating panel, destination direction data input to a hall operating panel, etc.). This causes the car 2b to move vertically from the departure hall X3 to the destination hall X3.

[0018] Furthermore, the processing device 2h may, for example, as in this embodiment, output the current position of the car 2b (car position) to the inspection device 4. Although not particularly limited, for example, the car position may be divided into 100 mm intervals, and the processing device 2h may output the current car position to the inspection device 4 every time the car 2b moves 100 mm.

[0019] The rope tester 3 may be configured to, for example, magnetize the rope 2a, detect the magnetic flux of the magnetized rope 2a, and output the detected magnetic flux to the inspection device 4. Also, for example, one rope tester 3 may be provided to inspect one rope 2a, or, for example, a plurality of rope testers 3 may be provided to inspect a plurality of ropes 2a simultaneously.

[0020] The rope tester 3 may be fixed to the machine room X2 inside the machine room X2 as in this embodiment, for example, or may be fixed to the hoistway X1 inside the hoistway X1, for example. In this way, the rope 2a moves relative to the rope tester 3 as the car 2b moves, so that the rope tester 3 inspects the rope 2a over its entire length.

[0021] Meanwhile, the inspection method of the rope 2a includes, for example, a leakage flux method for detecting magnetic flux leaking from the rope 2a, and a total flux method for detecting magnetic flux passing through the inside of the rope 2a. Although not particularly limited, the rope tester 3 may be, for example, a rope tester 3 for detecting magnetic flux by the leakage flux method as in the present embodiment, or may be, for example, a rope tester 3 for detecting magnetic flux by the total flux method, or may be, for example, a rope tester 3 for detecting magnetic flux by both the leakage flux method and the total flux method.

[0022] The leakage magnetic flux method detects magnetic flux leaking from the magnetized rope 2a and diagnoses the deterioration of the rope 2a. For example, if the surface of the rope 2a becomes uneven due to a break in a wire, magnetic flux leaks from the unevenness, and the rope 2a can be inspected (for example, to find a break) by detecting the leakage magnetic flux.

[0023] On the other hand, the total magnetic flux method detects the magnetic flux passing through the inside of the magnetized rope 2a and diagnoses the deterioration of the rope 2a. For example, if the rope 2a becomes thin in parts or becomes corroded or worn, changing its effective cross-sectional area (the cross-sectional area through which magnetic flux can pass), the magnetic flux passing through the inside of that part decreases, so by detecting that magnetic flux, the rope 2a can be inspected (for example, to find thinning, corrosion, wear, and breaks).

[0024] The inspection device 4 may be, for example, a portable terminal device. Although not particularly limited, the inspection device 4 may be, for example, a notebook computer, or may be, for example, a tablet computer, or may be, for example, a smart device (smartphone). Although not particularly limited, the inspection device 4 is, for example, disposed in the machine room X2 in this embodiment.

[0025] 3, the inspection device 4 may include an input unit 11 to which data is input, a processing unit 12 to process the data, and an output unit 13 to output the data. The processing unit 12 may include, for example, an acquisition unit 14 to acquire data, a storage unit 15 to store the data, a calculation unit 16 to calculate the data, and a control unit 17 to control each unit of the inspection device 4, as in this embodiment.

[0026] The inspection device 4 may be configured, for example, as one device, or may be configured, for example, as multiple devices that can communicate with each other. Specifically, the units 11, 12, and 13 of the inspection device 4 may be provided, for example, in one device, or may be provided, for example, distributed across multiple devices that can communicate with each other.

[0027] The configuration of the input unit 11 is not particularly limited, but the input unit 11 may be, for example, a mouse, a keyboard, a touch panel, a switch (a push button switch, a select switch, etc.), or the like.

[0028] The output unit 13 may include, for example, a display unit 18 that displays data, a sound generating unit 19 that generates the data as sound, and a transmission unit (not shown) that transmits the data to the outside (for example, the elevator 2, etc.) as in this embodiment. The configurations of the display unit 18 and the sound generating unit 19 are not particularly limited, but the display unit 18 may be, for example, a monitor, an electronic bulletin board, a display light, etc., and the sound generating unit 19 may be, for example, a buzzer, a speaker, etc.

[0029] The processing unit 12 may be a computer equipped with a processor such as a CPU and an MPU (e.g., the calculation unit 16, the control unit 17), a memory such as a ROM and a RAM (e.g., the acquisition unit 14, the storage unit 15), various interfaces, etc. As a result, the processor executes a program stored in the memory, and the respective units 14, 15, 16, and 17 of the processing unit 12 are realized by the cooperation of the software and hardware.

[0030] The processing unit 12 may be configured, for example, as one device, or may be configured, for example, as multiple devices that can communicate with each other. Specifically, the units 14, 15, 16, and 17 of the processing unit 12 may be provided, for example, in one device, or may be provided, for example, distributed among multiple devices that can communicate with each other.

[0031] The storage unit 15 may include, for example, an abnormality database storage unit 15a, an inter-hall distance storage unit 15b, and a magnetic flux / position storage unit 15c, as in this embodiment. Note that in this specification, storing does not only include the case where data is continuously stored until it is deleted by an input instruction, but also the case where data is temporarily stored for use in the calculation of the calculation unit 16 and deleted after the calculation is completed regardless of an input instruction.

[0032] The abnormality database storage unit 15a may store an abnormality database in which the cage position and abnormality data are associated with each other for each rope 2a, as in the present embodiment. The abnormality database may be data in which the abnormality data, the number of broken wires, and images are accumulated and stored for each inspection date, associated with the cage position, as shown in Fig. 4, for example.

[0033] For example, the inspection results for April 1, 2023 show that car positions "4," "N+1," and "N+5" are abnormal, the respective numbers of broken wires are "1," "3," and "0," and images of each are stored. Also, for example, the inspection results for car position "N+1" show that inspection dates "April 1, 2023," "February 1, 2023," and "December 1, 2022" are abnormal, the respective numbers of broken wires are "3," "2," and "2," and images of each are stored.

[0034] The image may be, for example, a photograph of an abnormal portion of the rope 2a, as shown in Fig. 5, in which the portion where the wire is broken is marked (for example, circled, etc.). This makes it possible to compare, for example, the rope 2a in a past photograph with the current rope 2a. Therefore, even if, for example, the portion where the wire is broken has moved from the surface to the inside of the rope 2a due to aging, this fact can be grasped.

[0035] The rope 2a includes, for example, a plurality of strands that are twisted together, and each strand includes a plurality of wires that are twisted together. If the number of broken wires, which is the number of broken wires, exceeds a set number, the strength of the rope 2a is insufficient, and the rope 2a is replaced.

[0036] Returning to Fig. 3, the inter-hall distance storage unit 15b may store an inter-hall distance for each elevator 2, for example, as in this embodiment. The inter-hall distance is the distance between adjacent halls X3, X3. For example, the distance between hall X3 on the first floor and hall X3 on the second floor is the distance between the car position where car 2b stops at hall X3 on the first floor and the car position where car 2b stops at hall X3 on the second floor.

[0037] The magnetic flux / position storage unit 15c may store the magnetic flux output by the rope tester 3 and the car position output by the processing device 2h in association with each other, as in the present embodiment. For example, the magnetic flux / position storage unit 15c may store the magnetic flux and the car position acquired by the acquisition unit 14 at the same timing in association with each other.

[0038] The calculation unit 16 may include, for example, an abnormality determination unit 16a and a car position calculation unit 16b, as in this embodiment.

[0039] The abnormality determination unit 16a may determine an abnormality in the magnetic flux based on the data stored in the magnetic flux / position storage unit 15c, for example, as in this embodiment. Specifically, when the magnitude of the magnetic flux detected by the rope tester 3 is abnormal, the portion of the rope 2a inspected by the rope tester 3 may be determined to be abnormal.

[0040] For example, in the rope tester 3 that detects magnetic flux by the leakage magnetic flux method as in this embodiment, if the magnitude of the magnetic flux detected by the rope tester 3 is greater than a set value, the portion of the rope 2a inspected by the rope tester 3 may be determined to be abnormal. Also, for example, in the rope tester 3 that detects magnetic flux by the total magnetic flux method, if the magnitude of the magnetic flux detected by the rope tester 3 is less than a set value, the portion of the rope 2a inspected by the rope tester 3 may be determined to be abnormal.

[0041] Incidentally, for example, in this embodiment, the position where the inspector checks the rope 2a is the installation position of the rope tester 3. As a result, the car position where the inspector positions the car 2b to check the rope 2a is the same as the car position stored in association with the magnetic flux determined to be abnormal by the abnormality determination unit 16a.

[0042] Therefore, in this embodiment, the car position calculation unit 16b sets the car position stored in association with the magnetic flux determined to be abnormal by the abnormality determination unit 16a as a confirmation car position, which is a car position for checking the rope 2a. Then, the car position calculation unit 16b may convert the confirmation car position into the nearest hall X3 and the distance from the nearest hall X3 based on the inter-hall distance stored in the inter-hall distance storage unit 15b, for example, as in this embodiment.

[0043] The nearest platform X3 may include, for example, both the nearest platform X3 above and the nearest platform X3 below the target car position. For example, if the target car position is between the Nth floor platform X3 and the N+1th floor platform X3, the nearest platform X3 may include both the Nth floor platform X3 and the N+1th floor platform X3.

[0044] Then, for example, by inputting setting data to the input unit 11, the nearest platform X3 may be set to, for example, the nearest platform X3 in the upward direction, or may be set to, for example, the nearest platform X3 in the downward direction, or may be set to, for example, the nearest platform X3 that is closest in distance. Note that this is not limited to such a case, and for example, the nearest platform X3 may be limited to one platform X3 that is closest in distance to the target car position.

[0045] The display unit 18 may, for example, as in this embodiment, include an object display unit 18a, an abnormal car position display unit 18b, an abnormality content display unit 18c, a position calculation display unit 18d, and a current position display unit 18e.

[0046] The object display unit 18a may display, for example, the elevator 2 and rope 2a to be inspected. The abnormal car position display unit 18b may display, for example, the car position to which abnormal data is associated and stored in the abnormality database. The abnormality content display unit 18c may display, for example, the abnormality data, the number of broken wires, and an image stored in the abnormality database to which the abnormality data is associated and stored in the abnormality database.

[0047] The position calculation display unit 18d may display, for example, the cage position calculated by the cage position calculation unit 16b. The current position display unit 18e may display, for example, the current cage position. Each of the display units 18a to 18e may display the respective data on a screen, for example, as in this embodiment.

[0048] The input unit 11 may, for example, as in this embodiment, include an elevator selection input unit 11a, a rope selection input unit 11b, an input selection input unit 11c, an abnormality content input unit 11d, an output selection input unit 11e, and a position selection input unit 11f.

[0049] The elevator selection input unit 11a may receive, for example, elevator selection data for selecting an elevator 2 to be inspected. The rope selection input unit 11b may receive, for example, rope selection data for selecting a rope 2a to be inspected.

[0050] The input selection input unit 11c may receive input selection data for selecting a car position for inputting data from among the car positions displayed on the abnormal car position display unit 18b. The abnormality content input unit 11d may receive, for example, the number of broken wires in the abnormal portion of the rope 2a and an image of the abnormal portion of the rope 2a.

[0051] The output selection input unit 11e may receive, for example, output selection data for selecting a target car position for outputting data from among the car positions displayed on the abnormal car position display unit 18b. The position selection input unit 11f may receive, for example, position selection data for selecting a target car position for checking the rope 2a from among the car positions displayed on the abnormal car position display unit 18b.

[0052] The configuration of the inspection system 1 according to this embodiment is as described above, and next, an inspection method of the inspection system 1 according to this embodiment will be described with reference to Fig. 6 to Fig. 9. Note that the following inspection method is provided as an example to help understand the inspection method of the inspection system 1, and is not intended to limit the inspection method of the inspection system 1.

[0053] The inspection method may include, for example, as in this embodiment, an abnormality detection step of detecting an abnormality by detecting the magnetic flux of the rope 2a with the rope tester 3, a car moving step of moving the car 2b to a checking car position where the abnormal part of the rope 2a can be checked, and an abnormality checking step of checking and storing the contents of the abnormality of the rope 2a. Note that the inspection device 4 may be in an abnormality detection mode in the abnormality detection step, in a car moving mode in the car moving step, and in an abnormality checking mode in the abnormality checking step.

[0054] <Anomaly detection process> First, the abnormality detection process will be described.

[0055] For example, elevator selection data for selecting the elevator 2 to be inspected is input to the elevator selection input unit 11a, and rope selection data for selecting the rope 2a to be inspected is input to the rope selection input unit 11b. As a result, as shown in Fig. 6, the object display unit 18a displays the selected elevator 2 and rope 2a to be inspected.

[0056] Although not particularly limited, the elevator selection input unit 11a and the rope selection input unit 11b may be configured, for example, so that data can be input by placing the mouse pointer on the position of the target display unit 18a and clicking the mouse, or may be configured, for example, so that data can be input by touching the position of the target display unit 18a.

[0057] The rope tester 3 is, for example, inside the machine room X2 and fixed to the machine room X2 (see FIG. 2). Thereafter, the car 2b moves upward, for example, from the landing X3 on the lowest floor, which is the inspection start position, to the landing X3 on the highest floor, which is the inspection end position. Although not particularly limited, the moving speed of the car 2b may be constant. At this time, the magnetic flux / position storage unit 15c stores, for example, the magnetic flux output by the rope tester 3 and the car position output by the processing device 2h in association with each other.

[0058] The abnormality determination unit 16a determines an abnormality in the magnetic flux based on, for example, the data stored in the magnetic flux / position storage unit 15c. Then, the abnormality database storage unit 15a accumulates and stores new abnormality data in the abnormality database of the rope 2a selected by the rope selection input unit 11b, for example, in association with the cage position stored in association with the magnetic flux determined to be abnormal.

[0059] Thereafter, as shown in Fig. 7, the abnormal car position display unit 18b displays, for example, in a list, the car positions associated with and stored in the abnormality database. For example, a car position associated with and stored as new (current inspection) abnormal data is displayed in the list as a new abnormal car position, and a car position not associated with and stored as new abnormal data but associated with and stored only as past (previous inspection) abnormal data is displayed in the list as a past abnormal car position.

[0060] In Figure 7, the new abnormal car positions are car positions "4," "N+1," and "N+3" that are displayed as "abnormal" among the car positions displayed in a list on the abnormal car position display unit 18b, and the past abnormal car position is car position "N+5" that is displayed as "normal" among the car positions displayed in a list on the abnormal car position display unit 18b.

[0061] As a result, by checking the new abnormal car position displayed in the list, the inspection results of the rope 2a can be easily understood. Also, by checking the past abnormal car positions displayed in the list, the new (current) and past (prior to the current) inspection results of the rope 2a can be easily understood. Therefore, for example, by comparing the new abnormal car position with the past abnormal car positions, the status of the rope 2a can be accurately understood.

[0062] The abnormal car position display unit 18b may display the new abnormal car position and the past abnormal car position in the same list, for example, as shown in Fig. 7. However, without being limited to such a configuration, the abnormal car position display unit 18b may display, for example, the new abnormal car position and the past abnormal car position in different, distinct lists.

[0063] Furthermore, the abnormal car position display unit 18b may be capable of simultaneously displaying some of the abnormal car positions as shown in Fig. 7, and displaying all of the abnormal car positions by performing an operation such as scrolling. Note that the abnormal car position display unit 18b is not limited to such a configuration, and may, for example, display all of the abnormal car positions simultaneously.

[0064] Furthermore, the wire break number display unit 18c may display the number of wire breaks and their inspection dates together with the car positions displayed in a list on the abnormal car position display unit 18b, as shown in Fig. 7. The displayed number of wire breaks may be, for example, the latest number of wire breaks among the numbers of wire breaks accumulated and stored in association with each car position in the abnormality database.

[0065] This makes it possible to easily grasp the latest number of broken wires, which is an abnormality in the rope 2a, and therefore to grasp, for example, the priority of checking the abnormal parts of the rope 2a. Therefore, for example, when there are a large number of car positions displayed on the abnormal car position display unit 18b and it is not possible to check the abnormal parts of all the ropes 2a on the day of inspection, this can be used as a reference to decide which abnormal parts of the rope 2a to check.

[0066] In addition, when the number of broken wires is not stored in the abnormality database, such as at cage position "N+3" (see Figure 4), the number of broken wires display unit 18c does not display the number of broken wires and the inspection date, as shown in Figure 7.

[0067] <Basket movement process> Next, the car movement process will be described.

[0068] For example, output selection data for selecting a target car position from among the car positions displayed in the abnormal car position display unit 18b is input to the output selection input unit 11e, and position selection data for selecting a target car position from among the car positions displayed in the abnormal car position display unit 18b is input to the position selection input unit 11f.

[0069] As a result, as shown in Fig. 8, in addition to the target display section 18a, the abnormality content display section 18c and the position calculation display section 18d are displayed. In Fig. 8, the cage position selected in the output selection input section 11e and the position selection input section 11f is "N+1".

[0070] Although not particularly limited, the output selection input unit 11e and the position selection input unit 11f may be configured, for example, so that data can be input by placing the mouse pointer on the car position position in the abnormal car position display unit 18b and clicking the mouse, or may be configured, for example, so that data can be input by touching the car position position in the abnormal car position display unit 18b.

[0071] As a result, in this embodiment, the input of output selection data by the output selection input unit 11e and the input of position selection data by the position selection input unit 11f are performed simultaneously by a common operation. Also, since the display of the abnormality content display unit 18c makes it possible to input the number of broken wires and an image at the target car position, as will be described later, in this embodiment, the input of input selection data by the input selection input unit 11c is also performed simultaneously by the same common operation.

[0072] For example, the input of output selection data by the output selection input unit 11e and the input of position selection data by the position selection input unit 11f may be performed separately by different operations. Also, for example, the input of input selection data by the input selection input unit 11c may be performed separately by a different operation from the input of output selection data by the output selection input unit 11e and the input of position selection data by the position selection input unit 11f.

[0073] The abnormality content display unit 18c displays, for example, a list of the number of broken wires and images accumulated and stored in association with the selected car position, which allows the user to easily grasp the change in the number of broken wires and the change in the images, which are abnormalities in the rope 2a.

[0074] 8, the abnormality content display unit 18c may simultaneously display the number of broken wires and a portion of the image, and may display the number of broken wires and all of the image by performing an operation such as scrolling. Note that the abnormality content display unit 18c is not limited to such a configuration, and may, for example, simultaneously display the number of broken wires and all of the image.

[0075] Furthermore, the car position calculation unit 16b may, for example, as in this embodiment, convert the confirmed car position for the car position selected in the position selection input unit 11f (in this embodiment, the same car position as the selected car position) into the nearest boarding station X3 and the distance from the nearest boarding station X3 based on the boarding station distance of the elevator 2 selected in the elevator selection input unit 11a among the boarding station distances stored in the boarding station distance memory unit 15b.

[0076] Then, the position calculation display unit 18d may display, for example, the nearest platform X3 and the distance from the nearest platform X3 converted by the car position calculation unit 16b as in this embodiment. This allows the position of the confirmation car position relative to the selected car position to be grasped. In this way, the confirmation car position is displayed by the nearest platform X3 and the distance from the nearest platform X3, so that the inspector can intuitively grasp, for example, the position of the confirmation car position.

[0077] Also, for example, as in this embodiment, the current position display unit 18e may be displayed together with the position calculation display unit 18d. For example, as in this embodiment, the current position display unit 18e may display the distance from the nearest platform X3 to the current car position. This allows the car 2b to be positioned at the confirmation car position for the selected car position by moving the car 2b to a position where the distance displayed on the position calculation display unit 18d matches the distance displayed on the current position display unit 18e.

[0078] At this time, first movement data for moving the car 2b to the nearest platform X3 is input to the input device 2g (see FIG. 1), so that the car 2b moves to the nearest platform X3 at a maximum speed of a first speed. Then, second movement data for moving the car 2b from the nearest platform X3 is input to the input device 2g, so that the car 2b moves from the nearest platform X3 at a maximum speed of a second speed that is slower than the first speed.

[0079] As a result, since the car 2b moves to the nearest platform X3 at a high speed, for example, the car 2b can be moved quickly to the nearest platform X3. Therefore, the car 2b can be moved efficiently. On the other hand, since the car 2b moves from the nearest platform X3 at a low speed, for example, the car 2b can be easily stopped at a confirmation car position for a selected car position.

[0080] Although not particularly limited, the input of the first movement data may be, for example, by pressing a destination floor button on a car operating panel, or may be, for example, by pressing a destination direction button on a hall operating panel, or may be, for example, by pressing a destination floor button on an inspector operating unit. Also, although not particularly limited, the input of the second movement data may be, for example, by pressing a movement button (e.g., an up movement button, a down movement button, etc.) on an inspector operating unit.

[0081] Furthermore, when car 2b is located at the confirmation car position for the selected car position, the output unit 13 may output, for example, a sound or a display. Although not particularly limited, for example, the display unit 18 may display an image indicating that car 2b is located at the car position, and for example, the sound unit 19 may emit a sound indicating that car 2b is located at the car position. In this way, by moving car 2b to a position where a sound or a display is output, car 2b can be positioned at the confirmation car position for the selected car position.

[0082] <Abnormality confirmation process> Next, the abnormality confirmation process will be described.

[0083] With the cage 2b located at the confirmation cage position for the selected cage position, the inspector checks, for example, the location of the rope 2a where the rope tester 3 is installed. At this time, the abnormality content display unit 18c displays the accumulated and stored number of broken wires and an image of the rope 2a in a list, so that the inspector can accurately grasp the current state of the rope 2a by comparing, for example, with the past number of broken wires and images.

[0084] Then, after the number of broken wires is confirmed and an image of the rope 2a is photographed and created, the number of broken wires and the image of the rope 2a are input to the abnormality content input unit 11d. Although not particularly limited, the abnormality content input unit 11d may be configured to allow data to be input by, for example, placing the mouse pointer on the position of the abnormality content display unit 18c and clicking the mouse, or may be configured to allow data to be input by, for example, touching the position of the abnormality content display unit 18c.

[0085] As a result, the abnormality database storage unit 15a accumulates and stores new abnormality data, the number of broken wires, and images in the abnormality database, for example, as shown in Fig. 9. Note that Fig. 9 shows that car position "N+5" was previously an abnormal car position (the magnetic flux was normal in the new inspection), but checking the rope 2a showed that the number of broken wires was "1".

[0086] [1] As described above, the elevator inspection system 1 according to the present embodiment has the following features: A rope tester 3 that detects and outputs the magnetic flux of the rope 2a; A processing device 2h for outputting the current cage position; The inspection device 4 includes a memory unit 15 for storing data, a calculation unit 16 for calculating the data, and an output unit 13 for outputting the data, The storage unit 15 stores the magnetic flux and the cage position in association with each other, The calculation unit 16 determines an abnormality in the magnetic flux, The storage unit 15 stores new abnormal data in association with the cage position stored in association with the magnetic flux determined to be abnormal, The output unit 13 includes a display unit 18 that displays, in a list, the cage positions associated with the new abnormality data and stored as new abnormal cage positions. This configuration is preferred.

[0087] According to this configuration, the cage position with which the new abnormal data is associated and stored is displayed in a list as a new abnormal cage position. This makes it possible to easily understand the inspection result of the rope 2a by checking the new abnormal cage position displayed in the list.

[0088] [2] In addition, in the elevator inspection system 1 described above in [1], as in this embodiment, The storage unit 15 stores an abnormality database in which the cage position and the abnormality data are associated with each other, The storage unit 15 accumulates and stores the new abnormality data in association with the cage position in the abnormality database. This configuration is preferred.

[0089] According to this configuration, the abnormality database accumulates and stores new abnormality data in association with the car position, thereby making it possible to accumulate and store past inspection results.

[0090] [3] In addition, in the elevator inspection system 1 described above in [2], as in this embodiment, The display unit 18 displays, in a list, the car positions stored in association with only the past abnormal data as past abnormal car positions. This configuration is preferred.

[0091] According to this configuration, the cage positions stored in association with only the past abnormality data are displayed in a list as past abnormal cage positions. This makes it possible to easily grasp the new and past inspection results of the rope 2a by checking the new abnormal cage positions and the past abnormal cage positions displayed in the list.

[0092] [4] In addition, in any one of the elevator inspection systems 1 described above in [1] to [3], as in this embodiment, The inspection device 4 includes an input unit 11 to which data is input, The input unit 11 receives input selection data for selecting a target car position from among the new abnormal car positions and the number of broken wires of the rope 2a, The storage unit 15 accumulates and stores the number of broken wires in the abnormality database in association with the car position selected by the input selection data, The display unit 18 displays the latest number of broken wires among the number of broken wires accumulated and stored in association with each car position together with the car position displayed in the list. This configuration is preferred.

[0093] According to this configuration, the latest number of broken wires is displayed together with the car position, making it possible to easily grasp the latest number of broken wires, which is an abnormality in the rope 2a.

[0094] [5] In addition, in any one of the elevator inspection systems 1 described above in [1] to [4], as in this embodiment, The inspection device 4 includes an input unit 11 to which data is input, The input unit 11 receives input selection data for selecting a target car position from among the new abnormal car positions and the number of broken wires of the rope 2a, The storage unit 15 accumulates and stores the number of broken wires in the abnormality database in association with the car position selected by the input selection data, The input unit 11 receives output selection data for selecting a target car position from among the car positions displayed in a list on the display unit 18, The display unit 18 displays, in a list, the number of wire breaks accumulated and stored in association with the car position selected by the output selection data. This configuration is preferred.

[0095] According to this configuration, the number of broken wires for the selected car position is displayed in a list, which makes it possible to easily grasp the change in the number of broken wires, which is an abnormality in the rope 2a.

[0096] [6] In addition, the inspection device 4, as in this embodiment, Used in any one of the elevator inspection systems 1 according to the above [1] to [5], The above configuration is preferable.

[0097] According to such a configuration, the inspection results of the rope 2a can be easily understood.

[0098] The elevator inspection system 1 and the inspection device 4 are not limited to the configurations of the above-mentioned embodiments, and are not limited to the above-mentioned effects. Of course, the elevator inspection system 1 and the inspection device 4 can be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations, methods, etc. of the various modified examples described below and adopt them in the configurations, methods, etc. of the above-mentioned embodiments.

[0099] (A) In the elevator inspection system 1 according to the above embodiment, the position where the inspector checks the rope 2a is the same as the installation position of the rope tester 3. The calculation unit 16 is configured to set the car position stored in association with the magnetic flux determined to be abnormal as the check car position, which is the car position for checking the rope 2a. However, the elevator inspection system 1 is not limited to such a configuration.

[0100] For example, the position where the inspector checks the rope 2a may be different from the installation position of the rope tester 3. The memory unit 15 may store correlation data between the car position stored in association with the magnetic flux (also called the "inspection car position") and the confirmation car position which is the car position for checking the rope 2a, and the calculation unit 16 may calculate the confirmation car position for the car position stored in association with the magnetic flux determined to be abnormal based on the correlation data.

[0101] For example, without being particularly limited, the rope tester 3 may be fixed to the hoistway X1 inside the hoistway X1, and the worker may check the location of the rope 2a facing the hoistway X1 on the car 2b. Also, without being particularly limited, the correlation data may be, for example, calculation data that calculates the confirmation car position from the inspection car position, or may be, for example, list data in which the confirmation car position is associated with each inspection car position and stored.

[0102] In this configuration, the order of the step of the calculation unit 16 determining an anomaly in the magnetic flux and the step of the calculation unit 16 calculating a confirmation car position for an inspection car position may be any. For example, the calculation unit 16 may determine an anomaly in the magnetic flux and then calculate a confirmation car position for only the inspection car position stored in association with the magnetic flux determined to be abnormal, or may determine an anomaly in the magnetic flux after calculating a confirmation car position for all inspection car positions associated with the magnetic flux.

[0103] (B) In addition, in the elevator inspection system 1 according to the above embodiment, the storage unit 15 is configured to accumulate and store new abnormality data, the number of broken wires, and images in association with the car position in the abnormality database. However, the elevator inspection system 1 is not limited to such a configuration.

[0104] For example, the storage unit 15 may be configured to store only the latest data of at least one of new abnormality data, the number of broken wires, and an image in association with the car position for the abnormality database, and to delete all previous data (do not accumulate and store).Furthermore, for example, the storage unit 15 may be configured not to store data from past inspection dates, i.e., not to store the abnormality database.

[0105] (C) In addition, in the elevator inspection system 1 according to the above embodiment, the contents of the abnormality that the storage unit 15 stores in association with the car position are new abnormality data, the number of broken wires, and an image. However, the elevator inspection system 1 is not limited to such a configuration.

[0106] For example, the content of the abnormality stored in the memory unit 15 in association with the car position may be only new abnormality data. Also, when the rope tester 3 detects magnetic flux by the total magnetic flux method, the content of the abnormality stored in the memory unit 15 in association with the car position may include the thickness of the rope 2a. Also, for example, the content of the abnormality stored in the memory unit 15 in association with the car position may be such that the new abnormality data also includes data related to other abnormalities (e.g., the number of broken wires, images, etc.).

[0107] (D) In ​​addition, in the elevator inspection system 1 according to the above embodiment, the display unit 18 is configured to display, in a list, the car positions that are stored in association with only past abnormality data as past abnormal car positions. However, the elevator inspection system 1 is not limited to such a configuration.

[0108] For example, the display unit 18 may be configured not to display a car position that is stored in association with only past abnormal data. Also, for example, the display unit 18 may be configured to display car positions that are stored in association with only past abnormal data one by one (not to display them in a list).

[0109] (E) In addition, in the elevator inspection system 1 according to the above embodiment, the display unit 18 is configured to display, together with the car positions displayed in a list, the latest number of broken wires among the accumulated and stored numbers of broken wires associated with each car position. However, the elevator inspection system 1 is not limited to this configuration. For example, the display unit 18 may be configured to display, together with the car positions displayed in a list, the accumulated and stored numbers of broken wires associated with each car position.

[0110] (F) In addition, in the elevator inspection system 1 according to the above embodiment, the storage unit 15 is configured to store an abnormality database for multiple ropes 2a. However, the elevator inspection system 1 is not limited to such a configuration. For example, the storage unit 15 may be configured to store an abnormality database for one rope 2a.

[0111] (G) In addition, in the elevator inspection system 1 according to the above embodiment, the storage unit 15 stores an abnormality database in which the car positions and abnormality data for the multiple ropes 2a are stored in association with each other, the input unit 11 receives rope selection data for selecting a target rope 2a from the multiple ropes 2a, and the storage unit 15 stores the abnormality data in association with the car position for the rope 2a selected by the rope selection data. However, the elevator inspection system 1 is not limited to such a configuration.

[0112] For example, the memory device 5 may store an abnormality database in which the cage position and abnormality data for multiple ropes 2a are associated with each other, the input unit 11 receives rope selection data for selecting a target rope 2a from the multiple ropes 2a, the output unit 13 outputs the rope selection data to the memory device 5, the memory device 5 outputs the abnormality database for the rope 2a selected by the rope selection data to the inspection device 4, and the memory unit 15 stores the abnormality data for the abnormality database output by the memory device 5 in association with the cage position.

[0113] (H) In addition, in the elevator inspection system 1 according to the above embodiment, the calculation unit 16 calculates the nearest landing X3 of the confirmation car position for the selected car position among the car positions with which the abnormality data is associated and stored based on the landing distance, and the display unit 18 displays the nearest landing X3. However, the elevator inspection system 1 is not limited to such a configuration.

[0114] For example, the display unit 18 may be configured not to display the nearest platform X3 calculated by the calculation unit 16. The calculation unit 16 may also be configured not to calculate the nearest platform X3 of the confirmed car position for the car position with which the abnormal data is associated and stored.

[0115] (I) In addition, in the elevator inspection system 1 according to the above embodiment, the calculation unit 16 converts the confirmation car position into the nearest landing X3 and the distance from the nearest landing X3 based on the landing distance, and the display unit 18 displays the nearest landing X3 and the distance from the nearest landing X3. However, the elevator inspection system 1 is not limited to such a configuration.

[0116] For example, the calculation unit 16 may be configured to calculate only the nearest platform X3 for the confirmed car position based on the platform distance. Also, for example, the display unit 18 may be configured to display only the nearest platform X3 as shown in FIG.

[0117] (J) In addition, in the elevator inspection system 1 according to the above embodiment, the display unit 18 is configured to display the distance from the nearest landing X3 (reference car position) to the check car position and the distance from the nearest landing X3 (reference car position) to the current car position together. However, the elevator inspection system 1 is not limited to such a configuration.

[0118] 10, the display unit 18 may be configured to display the distance from the lowest floor platform X3 (reference car position) which is the inspection start position to the confirmation car position, and the distance from the lowest floor platform X3 (reference car position) to the current car position together. That is, the reference car position may be the lowest floor platform X3 which is the inspection start position, instead of the nearest platform X3.

[0119] Also, for example, the display unit 18 may be configured to display the distance from the current car position to the confirmation car position as shown in Fig. 11. According to such a configuration, the car 2b can be positioned at the confirmation car position by moving the car 2b to a position where the distance becomes zero.

[0120] (K) In addition, in the elevator inspection system 1 according to the above embodiment, the output unit 13 is configured to output at least one of a sound and a display when the car 2b is located at the check car position. However, the elevator inspection system 1 is not limited to such a configuration.

[0121] For example, the output unit 13 may be configured to output first output data which is at least one of a sound and a display when the cage 2b is located at a confirmation cage position for a new abnormal cage position, and to output second output data which is at least one of a sound and a display when the cage 2b is located at a confirmation cage position for a past abnormal cage position, and the first output data may be different from the second output data so as to be distinguishable from the second output data.

[0122] The output unit 13 may be configured to output at least one of a sound and a display when the car 2b is located at a confirmation car position for a new abnormal car position, and not to output a sound or a display when the car 2b is located at a confirmation car position for a past abnormal car position. Also, for example, the output unit 13 may be configured to not output a sound or a display when the car 2b is located at a confirmation car position for a car position with which abnormal data is associated and stored.

[0123] (L) In addition, in the elevator inspection system 1 according to the above embodiment, the elevator 2b moves to the nearest landing X3 by inputting the first movement data, and the elevator 2b moves from the nearest landing X3 to the check elevator position by inputting the second movement data different from the first movement data. However, the elevator inspection system 1 is not limited to such a configuration.

[0124] For example, the input of one piece of movement data may cause the car 2b to move to a confirmed car position. Although not particularly limited, for example, the input unit 11 may receive position selection data for selecting a target car position from among the car positions displayed in a list on the display unit 18, the output unit 13 outputs a confirmation car position for the car position selected by the position selection data to the processing device 2h, and the processing device 2h moves the car 2b to the confirmed car position output by the output unit 13.

[0125] In such a configuration, the position selection input unit 11f may be configured, for example, as shown in FIG. 12, so that data can be input by placing the mouse pointer on the “Move” position of the car position in the abnormal car position display unit 18b and clicking the mouse, or may be configured, for example, so that data can be input by touching the “Move” position of the car position in the abnormal car position display unit 18b.

[0126] (M) In addition, in the elevator inspection system 1 according to the above embodiment, the maximum speed at which the car 2b moves to the nearest hall X3 is the first speed, and the maximum speed at which the car 2b moves from the nearest hall X3 is the second speed, the second speed being slower than the first speed. However, the elevator inspection system 1 is not limited to such a configuration. For example, the second speed may be the same as the first speed, or the second speed may be faster than the first speed.

[0127] (N) In the elevator inspection system 1 according to the above embodiment, the storage unit 15 is configured to store the hall distances of a plurality of elevators 2. However, the elevator inspection system 1 is not limited to such a configuration. For example, the storage unit 15 may be configured to store the hall distance of one elevator 2.

[0128] (O) In addition, in the elevator inspection system 1 according to the above embodiment, the storage unit 15 stores the inter-hall distances of the multiple elevators 2, the input unit 11 receives elevator selection data for selecting a target elevator 2 from the multiple elevators 2, and the calculation unit 16 calculates the nearest hall X3, etc., based on the inter-hall distances of the elevators 2 selected by the elevator selection data. However, the elevator inspection system 1 is not limited to such a configuration.

[0129] For example, the memory device 5 may store the inter-hall distances of multiple elevators 2, the input unit 11 may receive elevator selection data for selecting a target elevator 2 from the multiple elevators 2, the output unit 13 may output the elevator selection data to the memory device 5, the memory device 5 may output the inter-hall distances of the elevator 2 selected by the elevator selection data to the inspection device 4, and the calculation unit 16 may calculate the nearest hall X3, etc. based on the inter-hall distances output by the memory device 5.

[0130] (P) For example, in the elevator inspection system 1, as shown in FIG. 13, the calculation unit 16 may calculate the nearest landing X3 of the confirmation car position for each car position displayed in the list based on the inter-landing distance, and the display unit 18 may display the nearest landing X3 of the confirmation car position calculated for each abnormal car position together with the abnormal car position displayed in the list.

[0131] (Q) For example, in elevator inspection system 1, rope 2a may be divided into a standard region and a caution region where wire breakage is more likely to occur than in the standard region, and memory unit 15 may store the standard region or the caution region in association with the car position. In such a configuration, display unit 18 may display the region for each car position together with abnormal car positions displayed in a list, for example, or may display the region together with the displayed car positions.

[0132] For example, the caution area of ​​the rope 2a may be set to be the area where the rope is wound around the sheave of the hoisting machine 2d and curved when the car 2b is located at the landing X3, and the standard area of ​​the rope 2a may be set to be the area where the rope is away from the sheave of the hoisting machine 2d and straight regardless of which landing X3 the car 2b is located at.

[0133] (R) Note that, for example, the order of execution of each process, such as operations, procedures, steps, and stages, in the systems, methods, programs, and devices shown in the claims, specifications, and drawings, can be realized in any order, as long as the output of a previous process is not used in a subsequent process. For example, even if the description uses "first," "next," etc. for convenience, it does not mean that it is essential to execute the processes in that order. [Explanation of symbols]
