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

[0011] Here, before describing each component of the elevator inspection device, the detection device of the elevator and rope tester will be described with reference to Figs. 1 and 2.

[0012] As shown in FIG. 1, elevator 20 may include, for example, a plurality of car ropes 21, a car 22 and a counterweight 23 connected to the plurality of car ropes 21, a hoist 24 that drives the car ropes 21 to move the car 22 and the counterweight 23 up and down, a car rail 25 that guides the car 22, a counterweight rail 26 that guides the counterweight 23, an input device 27 to which data is input, a processing device 28 that processes the data, and an output device 29 that outputs the data.

[0013] 1 is configured such that the hoisting machine 24 is disposed inside the machine room X2, but is not limited to such a configuration. For example, the elevator 20 may be configured such that the machine room X2 is not provided and the hoisting machine 24 is disposed inside the hoistway X1.

[0014] The input device 27 may include, for example, a car operating panel 27a arranged in the car 22 and a hall operating panel 27b arranged in the hall X3. The output device 29 may include, for example, a car output unit 29a arranged in the car 22 and a hall output unit 29b arranged in the hall X3.

[0015] For example, during normal operation, the processing device 28 may control the hoist 24 based on data input to the input device 27 (for example, destination floor data input to the car operating panel 27a, destination direction data input to the hall operating panel 27b, etc.). As a result, the car 22 moves in the vertical direction from the departure hall X3 to the destination hall X3.

[0016] The number of the cage ropes 21 is not particularly limited. For example, six cage ropes 21a to 21f may be provided as shown in Fig. 2. For example, the cage ropes 21a to 21f arranged in a row in the horizontal direction are referred to as the first, second, third, fourth, fifth, and sixth cage ropes 21a to 21f in order from one side to the other side.

[0017] Therefore, for example, the cage rope 21b located one cage rope away from the first cage rope 21a is the second cage rope 21b, and for example, the cage rope 21c located two cage ropes away from the first cage rope 21a is the third cage rope 21c, and for example, the cage rope 21f located five cage ropes away from the first cage rope 21a is the sixth cage rope 21f.

[0018] The detection device 30 of the rope tester may include, for example, a plurality of sensor heads 31 and a support 32 that supports the sensor heads 31, as shown in Fig. 2. The sensor heads 31 may, for example, magnetize the cage rope 21 and detect the magnetic flux of the magnetized cage rope 21. Note that the number of sensor heads 31 is not particularly limited, but, for example, in Fig. 2, two sensor heads 31 are provided.

[0019] The detection device 30 may be fixed to the machine room X2, for example, inside the machine room X2, or may be fixed to the hoistway X1, for example, inside the hoistway X1. As a result, the car rope 21 moves (slides) relative to the sensor head 31 as the car 22 moves, so that the multiple sensor heads 31 simultaneously inspect the car rope 21 over the entire length.

[0020] The support 32 may be, for example, capable of freely changing the positions of the sensor heads 31, 31 that it supports. This allows the distance between the sensor heads 31, 31 supported by the support 32 to be freely changed, so that the positions of the sensor heads 31, 31 can be aligned with the position of the car rope 21 that is to be inspected at the same time.

[0021] 2 can support the sensor heads 31, 31 so that up to four adjacent car ropes 21a-21e (21b-21f) can be simultaneously inspected. Therefore, the detection device 30 in FIG. 2 has a maximum installation range of "5" (the range of five car ropes 21), and for example, the first car rope 21a and the sixth car rope 21f, which are five adjacent car ropes apart, cannot be simultaneously inspected.

[0022] 3, an elevator inspection system (hereinafter also simply referred to as an "inspection system") 1 may include, for example, an elevator inspection device (hereinafter also simply referred to as an "inspection device") 2 and a storage device 40 that stores data. The inspection device 2 and the storage device 40 may be able to communicate with each other by, for example, a communication means 50.

[0023] Although not particularly limited, the communication means 50 may be, for example, a wired communication means such as a wired LAN or a communication cable, or may be, for example, a wireless communication means such as the Internet, Bluetooth, a wireless LAN, etc. Note that the inspection device 2 may be capable of communicating with, for example, the elevator 20 and the sensor head 31 via the communication means 50.

[0024] The storage device 40 may be, for example, a server, etc. Although not particularly limited, the owner of the storage device 40 may be the same as or different from the owner of the elevator 20, the detection device 30 of the rope tester, and the inspection device 2, for example.

[0025] The inspection device 2 may be, for example, a portable terminal device. Although not particularly limited, the inspection device 2 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 2 is, for example, disposed in the machine room X2 in this embodiment.

[0026] The inspection device 2 may include, for example, an input unit 3 to which data is input, a processing unit 4 to process the data, and an output unit 5 to output the data. The processing unit 4 may include, for example, an acquisition unit 6 to acquire data, a storage unit 7 to store the data, a calculation unit 8 to calculate the data, and a control unit 9 to control each unit of the inspection device 2, as in this embodiment.

[0027] The inspection device 2 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 3, 4, and 5 of the inspection device 2 may be provided, for example, in one device, or may be provided, for example, distributed across multiple devices that can communicate with each other.

[0028] The configuration of the input unit 3 is not particularly limited, but the input unit 3 may be, for example, a mouse, a keyboard, a touch panel, a switch (a push button switch, a select switch, etc.), or the like.

[0029] The output unit 5 may include, for example, a display unit 10 that displays data, a sound generating unit 11 that generates the data as sound, and a transmission unit (not shown) that transmits the data to the outside (for example, an elevator 20, etc.) as in this embodiment. The configurations of the display unit 10 and the sound generating unit 11 are not particularly limited, but the display unit 10 may be, for example, a monitor, an electronic bulletin board, a display light, etc., and the sound generating unit 11 may be, for example, a buzzer, a speaker, etc.

[0030] The processing unit 4 may be a computer equipped with a processor such as a CPU and an MPU (e.g., the calculation unit 8, the control unit 9), a memory such as a ROM and a RAM (e.g., the acquisition unit 6, the storage unit 7), various interfaces, etc. As a result, the processor executes a program stored in the memory, and the respective units 6, 7, 8, and 9 of the processing unit 4 are realized by the cooperation of the software and hardware.

[0031] The processing unit 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 6, 7, 8, and 9 of the processing unit 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.

[0032] The input unit 3 may, for example, as in this embodiment, include a target selection input unit 3a into which target selection data for selecting the elevator 20 to be inspected is input, an inspection condition input unit 3b into which data on inspection conditions is input, and an inspection data input unit 3c into which data on inspection results is input.

[0033] The storage unit 7 may include, for example, an inspection data storage unit 7a that stores an inspection database and an inspection condition storage unit 7b that stores inspection conditions, as in this embodiment. In this specification, storing does not only include the case where data is continuously stored until 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 the input instruction.

[0034] The inspection database may be, for example, a database consisting of the most recent inspection time, the number of broken wires at the most recent inspection, and the number of years of use stored in association with the target elevator 20 and each of the multiple car ropes 21a to 21f, as shown in Figure 4.

[0035] For example, in the inspection data of the first cage rope (in FIG. 4, the cage rope with "Rope No." "1"; the same applies to FIGS. 8 and 9) 21a, the most recent inspection date is "June 1, 2023", the number of broken wires at the time of the most recent inspection is "0", and the number of years of use is "2.0 years". Note that, for example, with regard to the number of years of use, the inspection data storage unit 7a may store the date of start of use, and the calculation unit 8 may calculate the number of years of use from the date of start of use to the present day.

[0036] Although not shown, the cage rope 21 includes, for example, a plurality of strands that are twisted together, and each strand includes a plurality of wires that are twisted together. Then, for example, when the number of broken wires, which is the number of broken wires, exceeds a reference number, the cage rope 21 is not strong enough, and therefore the cage rope 21 is replaced.

[0037] Returning to Figure 3, the calculation unit 8 may, for example, as in this embodiment, be equipped with a priority determination unit 8a that determines the inspection priority of each of the multiple cage ropes 21 based on an inspection database, and a recommended rope selection unit 8b that selects a cage rope (hereinafter also referred to as a "recommended cage rope") 21 recommended for inspection in the current inspection based on the inspection priority determined by the priority determination unit 8a.

[0038] The display unit 10 may, for example, as in this embodiment, be equipped with a target display unit 10a that displays the elevator 20 to be inspected, an inspection data display unit 10b that displays the inspection data, a priority display unit 10c that displays the inspection priority determined by the priority determination unit 8a, and a recommended rope display unit 10d that displays the recommended car rope 21 selected by the recommended rope selection unit 8b.

[0039] The configuration of the inspection system 1 according to this embodiment is as described above, and next, a display method of the inspection device 2 according to this embodiment will be described with reference to Fig. 4 to Fig. 9. Note that the following method is provided as an example to help understand the display method of the inspection device 2, and is not intended to limit the display method of the inspection device 2.

[0040] The display method may include, for example, as in this embodiment, an inspection data storage step of storing an inspection database for the elevator 20 to be inspected, a priority determination step of determining the inspection priority of the car ropes 21, a recommended rope selection step of selecting the car ropes 21 recommended for inspection in the current inspection, and a data display step of displaying data on the display unit 10.

[0041] <Test data storage process> First, the inspection data storage step will be described.

[0042] For example, target selection data for selecting elevator 20 to be inspected is input to target selection input unit 3a. Although not particularly limited, each of input units 3a to 3c may be configured to input data by, for example, placing a mouse pointer on a predetermined position on display unit 10 and clicking the mouse, or may be configured to input data by, for example, touching a predetermined position on display unit 10.

[0043] For example, the output unit 5 may output the target selection data to the memory device 40, and the memory device 40 may output the inspection database of the elevator 20 selected by the target selection data output by the output unit 5 from the inspection databases of the multiple elevators 20 stored therein to the inspection device 2, and the inspection data memory unit 7a may store the inspection database output by the memory device 40.

[0044] This allows the inspection data to be shared. Therefore, for example, even if the previous inspector and the current inspector are different, there is no need for a meeting to share the inspection data. Note that the present invention is not limited to such a configuration, and for example, the inspection data storage unit 7a may be configured to store an inspection database for a plurality of elevators 20. In other words, the display method does not need to include an inspection data storage step.

[0045] <Priority determination process> Next, the priority determination process will be described.

[0046] The priority determination unit 8a may determine the inspection priority of each of the plurality of cage ropes 21a-21f based on an inspection database stored in the inspection data storage unit 7a, for example, as shown in Fig. 4 to Fig. 8. Specifically, the priority determination unit 8a may determine the inspection priority of each of the plurality of cage ropes 21a-21f based on the most recent inspection time, the number of broken wires at the time of the most recent inspection, and the number of years of use, as in this embodiment, for example.

[0047] Also, although not particularly limited, the priority determination unit 8a may determine the inspection priority by calculating the priority points of each of the cage ropes 21a to 21f, for example, as in this embodiment. Note that, for example, as in this embodiment, the priority points may be the sum of the priority points of the most recent inspection time, the number of broken wires at the most recent inspection, and the number of years of use. Also, for example, as in this embodiment, the larger the priority point, the higher the inspection priority.

[0048] As shown in Fig. 5, for the most recent inspection time, for example, the more recent the inspection time, the smaller the priority point, and the older the inspection time, the larger the priority point. In Fig. 5, for example, if the most recent inspection time is "more than January to within February", the priority point is "1", and if the most recent inspection time is "more than March to within April", the priority point is "5".

[0049] For example, in Fig. 5, if today (the current inspection date) is "July 1, 2023" and the most recent inspection period is "May 1 to May 31, 2023," the priority point is "1," and if the most recent inspection period is "March 1 to March 31, 2023," the priority point is "5." Note that the priority points for the most recent inspection period are not limited to these.

[0050] As shown in Fig. 6, in terms of the number of broken wires at the most recent inspection, for example, the fewer the number of broken wires, the smaller the priority point, and the more the number of broken wires, the larger the priority point. In Fig. 6, for example, if the number of broken wires is "more than 0% to within 20% of the reference number", the priority point is "1", and if the number of broken wires is "more than 40% to within 60% of the reference number", the priority point is "3".

[0051] 6, for example, if the reference number (e.g., the reference number for replacing the cage rope 21) is "10," and the number of broken wires is "1 to 2," the priority point is "1," and if the number of broken wires is "5 to 6," the priority point is "3." Note that the priority point based on the number of broken wires at the time of the most recent inspection is not limited to this.

[0052] As shown in Fig. 7, for example, the shorter the years of use, the smaller the priority points may be, and the longer the years of use, the larger the priority points may be. In Fig. 7, for example, if the years of use are "more than (base years - 1.0 years) to within (base years - 0.5 years)", the priority points are "1", and if the years of use are "more than (base years ± 0 years)", the priority points are "5".

[0053] 7, for example, if the reference age (e.g., the reference age for replacing the cage rope 21) is "5 years," and the age is "more than 4 years to within 4.5 years," the priority point is "1," and if the age is "more than 5 years," the priority point is "5." Note that the priority points for the age are not limited to these.

[0054] Then, the priority determination unit 8a calculates the priority points of each of the first to sixth cage ropes 21a to 21f, for example, as shown in Fig. 8. For example, for the second cage rope 21b, the most recent inspection date is "May 1, 2023," so the priority point is "1," the number of broken wires at the most recent inspection is "5," so the priority point is "3," and the number of years of use is "4.8 years," so the priority point is "2," and the total priority points indicating the inspection priority is "6."

[0055] In this way, the inspection priority of each of the cage ropes 21a-21f is determined based on the most recent inspection time, the number of broken wires at the most recent inspection, and the years of use, so that the inspection priority of each of the cage ropes 21a-21f can be appropriately determined. Note that the priority determination unit 8a is not limited to such a configuration, and may determine the inspection priority according to a plurality of ranks (for example, ranks such as "high-medium-low").

[0056] <Recommended rope selection process> Next, the recommended cage rope selection process will be described.

[0057] The recommended rope selection unit 8b may select a recommended cage rope 21 for which inspection is recommended based on the inspection priority determined by the priority determination unit 8a and the inspection conditions stored in the inspection condition storage unit 7b, for example, as in this embodiment. Note that the inspection conditions stored in the inspection condition storage unit 7b may include, for example, invariant (prescribed) inspection conditions set in advance and variable (individual) inspection conditions input to the inspection condition input unit 3b and set for each inspection.

[0058] The invariable inspection condition may include, for example, a condition that when multiple car ropes 21 recommended for simultaneous inspection are selected in the current inspection, the selected multiple car ropes 21 are combined so as to be spaced apart by at least two adjacent positions from each other. This allows the sensor heads 31, 31 to be spaced apart from each other when multiple car ropes 21 are inspected simultaneously.

[0059] Therefore, interference between the magnetic fields of the sensor heads 31, 31 can be suppressed, and the cage rope 21 can be appropriately inspected by the sensor head 31. Note that, for example, the inspection conditions may be variable inspection conditions input to the inspection condition input unit 3b, rather than being preset, unchanging inspection conditions.

[0060] The variable inspection conditions may also include, for example, the specifications of the detection device 30 used in the current inspection. Specifically, for example, the variable inspection conditions may include a set number that is the number of cage ropes 21 to be simultaneously inspected in the current inspection, and a maximum installation range of the sensor head 31.

[0061] For example, in this embodiment, since the detection device 30 according to Fig. 2 is used, the set number is "2", and the maximum installation range of the sensor head 31 is "5" (range of five cage ropes 21). Note that, for example, the inspection conditions may be preset, unchanging inspection conditions, rather than variable inspection conditions input to the inspection condition input unit 3b.

[0062] 8, for example, the recommended rope selection unit 8b may select a set number of currently recommended car ropes 21 that are recommended for simultaneous inspection in the current inspection, and a set number of next recommended car ropes 21 that are recommended for simultaneous inspection in the next inspection. Specifically, the recommended rope selection unit 8b may select the currently recommended car ropes 21 and the next recommended car ropes 21 as follows.

[0063] First, because the set number, which is an inspection condition, is "2", the four cage ropes 21b, 21c, 21f, and 21d are selected in order of decreasing inspection priority as the current recommended cage rope 21 and the next recommended cage rope 21. Specifically, the four cage ropes 21b (priority point "6"), the third cage rope 21c (priority point "5"), the sixth cage rope 21f (priority point "3"), and the fourth cage rope 21d (priority point "2") are selected in order of decreasing priority points as the current recommended cage rope 21 and the next recommended cage rope 21.

[0064] Then, the second cage rope 21b having the highest inspection priority is selected as the current recommended cage rope 21. Next, the third cage rope 21c having the second highest inspection priority is the cage rope 21c located one cage rope away from the second cage rope 21b. As a result, the second and third cage ropes 21b, 21c cannot be inspected simultaneously, so the third cage rope 21c is selected as the next recommended cage rope 21.

[0065] The sixth cage rope 21f, which has the third highest inspection priority, is the cage rope 21f located four cage ropes away from the second cage rope 21b. This allows the second and sixth cage ropes 21b, 21f to be inspected simultaneously, so the sixth cage rope 21f can be selected as the currently recommended cage rope 21.

[0066] However, the fourth cage rope 21d, which has the fourth highest inspection priority, is the cage rope 21c located one cage rope away from the third cage rope 21c. As a result, the third and fourth cage ropes 21c, 21d cannot be inspected simultaneously at the next inspection, so the fourth cage rope 21d is selected as the cage rope 21 recommended this time, and the sixth cage rope 21f is selected as the cage rope 21 recommended next time.

[0067] Therefore, the second and fourth car ropes 21b, 21d are selected as the current recommended car ropes 21 (indicated as "current" in FIG. 8), and the third and sixth car ropes 21c, 21f are selected as the next recommended car ropes 21 (indicated as "next" in FIG. 8). In this way, it is possible to select a combination of car ropes 21 to be inspected simultaneously, taking into consideration not only the current inspection but also the next inspection. Therefore, for example, it is possible to inspect appropriate car ropes 21 not only for the current inspection but also for the next inspection.

[0068] <Data display process> Next, the data display process will be described.

[0069] As shown in Figure 9, the display unit 10 may be configured, for example, to display the elevator 20 to be inspected in the object display unit 10a, to display the inspection data in the inspection data display unit 10b, to display the inspection priority determined by the priority determination unit 8a in the priority display unit 10c, and to display the recommended car rope 21 selected by the rope selection unit 8b in the recommended rope display unit 10d.

[0070] This makes it possible to grasp the cage ropes 21b, 21d that should be inspected in the current inspection among the multiple cage ropes 21a to 21f. Therefore, the cage rope 21 to be inspected in the current inspection can be easily determined, and therefore, for example, the inspection of the cage rope 21 can be easily planned. In addition, since both the inspection data and the inspection priority are displayed, it is possible to grasp, for example, the basis for which cage ropes 21b, 21d should be inspected in the current inspection.

[0071] Although not particularly limited, for example, the conditions of the car rope 21 to be inspected in the current inspection may be input to the inspection condition input unit 3b. In such a case, the recommended rope selection unit 8b may reselect the current recommended car rope 21 and the next recommended car rope 21, and the recommended rope display unit 10d may display the reselected current recommended car rope 21.

[0072] For example, in Figures 8 and 9, when conditions for inspecting the third cage rope 21c in the current inspection are input into the inspection condition input unit 3b, the recommended rope selection unit 8b will select the third and sixth cage ropes 21c, 21f as the current recommended cage ropes 21, and select the second and fourth cage ropes 21b, 21d as the next recommended cage ropes 21, using the same selection method as described above.

[0073] Thereafter, although not limited thereto, for example, the car rope 21 may be inspected by the calculation unit 8 determining an abnormality in the car rope 21 based on the magnetic flux output by the sensor head 31. Then, the current inspection data is input to the inspection data input unit 3c, whereby the storage unit 7 updates and stores the inspection database, and the output unit 5 outputs the inspection database updated and stored in the storage unit 7 to the storage device 40, and the storage device 40 may update and store the inspection database output by the output unit 5 as the inspection database of the elevator 20.

[0074] [1] As described above, the elevator inspection device 2, as in this embodiment, A memory unit 7 that stores the most recent inspection time of each of the multiple cage ropes 21a to 21f to be inspected by the rope tester; A calculation unit 8 that determines an inspection priority of each of the plurality of cage ropes 21a to 21f based on the stored most recent inspection time; A display unit 10 that displays the determined inspection priority. This configuration is preferred.

[0075] According to this configuration, the inspection priority of each of the plurality of car ropes 21a to 21f is determined based on the stored most recent inspection time, and the determined inspection priority is displayed. This allows the user to know which of the plurality of car ropes 21a to 21f should be inspected in the current inspection.

[0076] [2] In addition, the elevator inspection device 2, as in this embodiment, A memory unit 7 that stores the most recent inspection time of each of the multiple cage ropes 21a to 21f to be inspected by the rope tester; a calculation unit 8 that determines an inspection priority of each of the plurality of car ropes 21a to 21f based on the stored most recent inspection time, and selects a recommended car rope 21 that is recommended for inspection in the current inspection based on the determined inspection priority; A display unit 10 that displays the selected recommended cage rope 21. This configuration is preferred.

[0077] According to such a configuration, the inspection priority of each of the multiple car ropes 21a to 21f is determined based on the most recent inspection time that has been stored. Then, the recommended car rope 21 that is recommended to be inspected in the current inspection is selected based on the determined inspection priority, and the selected recommended car rope 21 is displayed. This makes it possible to grasp the car ropes 21b, 21d that should be inspected in the current inspection among the multiple car ropes 21a to 21f.

[0078] [3] In addition, in the elevator inspection device 2 described above in [2], as in this embodiment, The calculation unit 8 selects a set number of currently recommended car ropes 21 that are recommended for simultaneous inspection in a current inspection, so that a combination of the set number of car ropes 21 is such that the set number of car ropes 21 are spaced apart from each other by at least two adjacent positions based on the determined inspection priority, The display unit 10 displays the currently recommended cage rope 21 selected. This configuration is preferred.

[0079] According to such a configuration, a set number of currently recommended car ropes 21 that are recommended for simultaneous inspection in the current inspection are selected based on the determined inspection priority, and the selected set number of currently recommended car ropes 21 are displayed. At this time, since the combination of the set number of currently recommended car ropes 21 is selected such that the multiple car ropes 21a to 21f are spaced apart by at least two adjacent positions from each other, it is possible to select a combination of the car ropes 21 so as to suppress interference between the sensor heads 31, 31 that simultaneously inspect the multiple car ropes 21a to 21f.

[0080] [4] In addition, in the elevator inspection device 2 described in [3] above, as in this embodiment, The calculation unit 8 further selects not only the set number of currently recommended car ropes 21 but also the set number of next recommended car ropes 21 that are recommended for simultaneous inspection in the next inspection, so that the set number of car ropes 21 are combined such that they are spaced apart by at least two adjacent car ropes from each other, based on the determined inspection priority. This configuration is preferred.

[0081] According to this configuration, a set number of currently recommended car ropes 21 recommended for simultaneous inspection in the current inspection and a set number of next recommended car ropes 21 recommended for simultaneous inspection in the next inspection are selected. This makes it possible to suppress interference between the sensor heads 31, 31 that simultaneously inspect the multiple car ropes 21a to 21f, and to select a combination of the car ropes 21 taking into consideration not only the current inspection but also the next inspection.

[0082] [5] In addition, in any one of the elevator inspection devices 2 described above in [1] to [4], as in this embodiment, The memory unit 7 further stores the number of years of use of each of the plurality of cage ropes 21a to 21f, The calculation unit 8 determines the inspection priority of each of the plurality of cage ropes 21a to 21f based on the stored most recent inspection time and the number of years of use. This configuration is preferred.

[0083] According to such a configuration, the inspection priority of each of the plurality of car ropes 21a to 21f is determined based on the stored most recent inspection time and years of use, so that the inspection priority of each of the car ropes 21a to 21f can be appropriately determined.

[0084] [6] In addition, in any one of the elevator inspection devices 2 described above in [1] to [5], as in this embodiment, The memory unit 7 further stores the number of wire breaks in the most recent inspection of each of the plurality of cage ropes 21a to 21f, The calculation unit 8 determines the inspection priority of each of the plurality of cage ropes 21a to 21f based on the stored most recent inspection time and the number of broken wires. This configuration is preferred.

[0085] According to this configuration, the inspection priority of each of the multiple cage ropes 21a to 21f is determined based on the stored most recent inspection time and the number of broken wires at the time of the most recent inspection, so that the inspection priority of the cage ropes 21a to 21f can be appropriately determined.

[0086] The elevator inspection device 2 is not limited to the configuration of the embodiment described above, and is not limited to the above-mentioned effects. Of course, various modifications can be made to the elevator inspection device 2 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. related to the various modified examples described below and adopt them in the configurations, methods, etc. related to the embodiment described above.

[0087] (A) In the elevator inspection device 2 according to the above embodiment, the display unit 10 is configured to display the inspection priority determined by the calculation unit 8 and the recommended car rope 21 selected by the calculation unit 8. However, the elevator inspection device 2 is not limited to such a configuration.

[0088] (A-1) For example, the display unit 10 may be configured to display only the inspection priority determined by the calculation unit 8, without displaying the recommended car rope 21. With such a configuration, the inspection priority of each of the multiple car ropes 21a-21f can be grasped, and therefore it is possible to grasp the car ropes 21b, 21d that should be inspected in the current inspection among the multiple car ropes 21a-21f. Note that in such a configuration, the calculation unit 8 may be configured not to calculate the recommended car rope 21.

[0089] (A-2) Also, for example, the display unit 10 may be configured to display only the recommended car rope 21 selected by the calculation unit 8, without displaying the inspection priority determined by the calculation unit 8. With such a configuration, the selected recommended car rope 21 can be grasped, and therefore the car ropes 21b, 21d that should be inspected in the current inspection, among the multiple car ropes 21a to 21f, can be grasped.

[0090] (B) In addition, in the elevator inspection device 2 according to the above embodiment, the number of settings for which the currently recommended car rope 21 is selected is two (multiple). However, the elevator inspection device 2 is not limited to such a configuration. The number of settings for which the currently recommended car rope 21 is selected may be, for example, one, or may be, for example, three or more.

[0091] (C) In addition, in the elevator inspection device 2 according to the above embodiment, the multiple recommended car ropes 21 selected by the calculation unit 8 are configured to be a combination of multiple car ropes 21 that are spaced apart from each other by at least two adjacent car ropes 21. However, the elevator inspection device 2 is not limited to such a configuration.

[0092] For example, the configuration may be such that each of the multiple recommended car ropes 21 selected by the calculation unit 8 may be a combination including two adjacent car ropes 21. Also, for example, the multiple currently recommended car ropes 21 selected by the calculation unit 8 may be a combination in which the multiple car ropes 21 are spaced apart by two or more adjacent car ropes 21, while the multiple next recommended car ropes 21 selected by the calculation unit 8 may be a combination including two adjacent car ropes 21.

[0093] (D) In ​​the elevator inspection device 2 according to the above embodiment, the calculation unit 8 is configured to select a set number of currently recommended car ropes 21 and a set number of next recommended car ropes 21. However, the elevator inspection device 2 is not limited to this configuration. For example, the calculation unit 8 may be configured to select only the set number of currently recommended car ropes 21 without selecting the next recommended car rope 21.

[0094] (E) In addition, in the elevator inspection device 2 according to the above embodiment, the number of currently recommended car ropes 21 selected by the calculation unit 8 is the same as the number of next recommended car ropes 21. However, the elevator inspection device 2 is not limited to such a configuration.

[0095] For example, the configuration may be such that the set number of the currently recommended car ropes 21 selected by the calculation unit 8 is different from the set number of the next recommended car ropes 21. Note that in this way, when the inspection conditions for the next inspection are different from the inspection conditions for the current inspection (for example, when the detection device 30 to be used is different), for example, a configuration may be such that each inspection condition (variable inspection conditions) can be individually input to the inspection condition input unit 3b, or, for example, a configuration may be such that each inspection condition (unchanging inspection conditions) is stored in advance in the inspection condition storage unit 7b.

[0096] (F) In addition, in the elevator inspection device 2 according to the above embodiment, the display unit 10 is configured to display only the currently recommended car rope 21, without displaying the next recommended car rope 21. However, the elevator inspection device 2 is not limited to such a configuration. For example, the display unit 10 may be configured to display both the currently recommended car rope 21 and the next recommended car rope 21.

[0097] (G) In addition, in the elevator inspection device 2 according to the above embodiment, the calculation unit 8 is configured to determine the inspection priority of each of the plurality of car ropes 21a to 21f based on the most recent inspection time, the number of broken wires at the time of the most recent inspection, and the years of use. However, the elevator inspection device 2 is not limited to such a configuration.

[0098] For example, the calculation unit 8 may be configured to determine the inspection priority of each of the plurality of cage ropes 21a-21f based only on the most recent inspection time and the number of broken wires at the most recent inspection. Also, for example, the calculation unit 8 may be configured to determine the inspection priority of each of the plurality of cage ropes 21a-21f based only on the most recent inspection time and the number of years of use. Also, for example, the calculation unit 8 may be configured to determine the inspection priority of each of the plurality of cage ropes 21a-21f based only on the most recent inspection time. In these configurations, the storage unit 7 may be configured to store only data used in determining the inspection priority.

[0099] (H) 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 the processes must be executed in that order. [Explanation of symbols]
