Description

[Technical Field]

[0001] The present invention relates to an evaluation system and evaluation method for evaluating vibrations of elevator car floors and escalator steps. [Background technology]

[0002] Various techniques have been proposed for measuring vibrations that occur in an elevator car when the elevator is in operation, one example of which is the technique disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-24704 Summary of the Invention [Problem to be solved by the invention]

[0004] Traditionally, measurements of elevator car vibrations during operation are performed for each elevator, but when multiple elevators are installed in the same building, a comprehensive vibration evaluation is ultimately performed for all elevators installed in the building. This is to ensure that passengers can enjoy the same ride comfort regardless of which elevator they are using. Similar evaluations are also performed for escalators, which have circulating steps that transport people. In the following, elevators and escalators are collectively referred to as the "passenger conveyor." Furthermore, in the following, elevator cars and escalator steps are collectively referred to as the "carrier."

[0005] When multiple passenger conveyors are installed in the same building, there has previously been no technology for comprehensively evaluating the vibrations that occur in each conveying body when the multiple passenger conveyors are in operation.

[0006] An object of the present invention is to provide a system and method that can comprehensively evaluate vibrations that occur in each of a plurality of passenger conveyors installed in the same building when they are in operation. [Means for solving the problem]

[0007] The passenger conveyor evaluation system according to the present invention comprises: a measuring device that is installed on a transport body of a passenger conveyor, that measures vibrations that occur on the transport body when the passenger conveyor is operated at a constant speed by decomposing the vibrations into three mutually orthogonal axial directions including a vertical axis, and that generates vibration data that represent the vibrations measured in each axial direction; an evaluation device that communicates with the measurement device to acquire vibration data representing vibrations in the three axial directions that occur in each of the plurality of passenger conveyors when the conveyors are operated at a constant speed, evaluates the magnitude of vibrations in each axial direction that occur in each of the plurality of passenger conveyors based on the acquired vibration data, and outputs an evaluation result of the vibrations for each of the plurality of passenger conveyors; Includes:

[0008] This allows the vibration evaluation results for each of multiple passenger conveyors to be output in a row for each of the three axial directions, making it easier to compare these evaluation results and enabling a comprehensive evaluation of the vibrations that occur in each of the conveying bodies when multiple passenger conveyors are in operation.

[0009] The evaluation device The magnitude of vibration in each axial direction occurring in each conveying body of the plurality of passenger conveyors can be evaluated by comparing the target value for the magnitude of vibration in each axial direction set for the plurality of passenger conveyors with the magnitude of vibration in each axial direction represented by the vibration data.

[0010] This makes it possible to comprehensively evaluate the vibrations that occur in each conveying body when multiple passenger conveyors are in operation, using target values ​​for the magnitude of vibration in each axial direction set for the multiple passenger conveyors as a reference.

[0011] The evaluation device An evaluation value corresponding to the difference between the target value and the magnitude of vibration in each axial direction represented by the vibration data can be output for each of the plurality of passenger conveyors.

[0012] This makes it possible to comprehensively evaluate the vibrations that occur in each conveying body when multiple passenger conveyors are in operation through the evaluation value.

[0013] The evaluation device The evaluation value can be output in a different color depending on the difference between the target value and the magnitude of vibration in each axial direction represented by the vibration data.

[0014] This makes it possible to comprehensively evaluate the vibrations that occur in each conveying body when multiple passenger conveyors are in operation through the colors assigned to the evaluation values.

[0015] The evaluation device Table 1 shows the evaluation values ​​and vibration magnitudes for each passenger conveyor, each operating direction, and each axial direction. a second table in which the occurrence frequencies of the evaluation values ​​across the plurality of passenger conveyors are arranged for each axial direction; and, a graph showing a distribution of the frequency of appearance of the evaluation values ​​in each axial direction across the plurality of passenger conveyors and a distribution of the frequency of appearance of the evaluation values ​​across the three axes; A report including at least one of the following can be output.

[0016] This allows for a report to be obtained regarding the evaluation of vibrations that occur on each conveyor when multiple passenger conveyors are in operation.

[0017] Further, the evaluation method of the passenger conveyor according to the present invention includes: a measuring device that is installed on a transport body of a passenger conveyor, measures vibrations that occur on the transport body when the passenger conveyor is operated at a constant speed by dividing the vibrations into three mutually perpendicular axial directions including a vertical axis, and generates vibration data that represent the vibrations measured in each axial direction, and measures vibrations that occur on each transport body of a plurality of passenger conveyors when each of the plurality of passenger conveyors is operated at a constant speed; acquiring the vibration data, and inputting the vibration data into an evaluation device that evaluates the magnitude of vibration in each axial direction generated in each of the conveying bodies of the plurality of passenger conveyors based on the acquired vibration data and outputs an evaluation result, thereby causing the evaluation device to output the vibration evaluation results for each of the plurality of passenger conveyors in a row for each of the three axial directions; Includes:

[0018] This allows the vibration evaluation results for each of multiple passenger conveyors to be output in a row for each of the three axial directions, making it easier to compare these evaluation results and enabling a comprehensive evaluation of the vibrations that occur in each of the conveying bodies when multiple passenger conveyors are in operation.

[0019] [Figure 1] FIG. 1 is a diagram showing an example of the configuration of an evaluation system according to one embodiment of the present invention. [Figure 2] FIG. 2 is an explanatory diagram of the X-axis, Y-axis, and Z-axis of this embodiment. [Figure 3] FIG. 3 is a diagram showing an example of a report displayed on the display device. [Figure 4] FIG. 4 is a flowchart showing the flow of the evaluation method in this embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, a passenger conveyor evaluation system and evaluation method according to the present invention will be described with reference to the drawings.

[0021] 1 is a diagram showing an example of the configuration of an evaluation system 1 according to one embodiment of the present invention. Evaluation system 1 is a computer system for comprehensively evaluating vibrations that occur in each of multiple passenger conveyors installed in a building such as a commercial building during operation. In this embodiment, the passenger conveyor whose vibration is to be evaluated is an elevator, and the conveyor is an elevator car 40.

[0022] As shown in FIG. 1, the evaluation system 1 includes a measuring device 10 installed in an elevator car 40 whose vibration is to be evaluated, and an evaluation device 20 that communicates with the measuring device 10 via a communication network 30, which is a telecommunications line such as the Internet.

[0023] The measuring device 10 is a portable device that is carried into the car 40 by a worker performing work for vibration evaluation. The measuring device 10 carried into the car 40 by the worker is installed on the floor of the car 40. As shown in FIG. 1 , the measuring device 10 includes a vibration sensor 110 and a communication device 120.

[0024] The vibration sensor 110 includes, for example, a three-axis acceleration sensor and a geomagnetic sensor. The vibration sensor 110 measures the vibrations generated in the car 40 when the elevator is operating at a constant speed by breaking them down into three mutually orthogonal axial directions, including the vertical axis Z, and generates vibration data representing the vibrations measured in each axial direction. In this embodiment, as shown in Fig. 2, of the two axes orthogonal to the vertical axis (hereinafter referred to as the Z axis), which is the ascending and descending direction of the car 40, the axis along the opening and closing direction of the door of the car 40 is set as the X axis, and the Y axis is set as the axis orthogonal to the Z axis and the X axis.

[0025] The vibration data represents the change over time in acceleration in each of the X-axis, Y-axis, and Z-axis directions. When the elevator is operating at a constant speed, the acceleration in the Z-axis direction should be zero. If the acceleration in the Z-axis direction detected by the vibration sensor 110 is not zero when the elevator is operating at a constant speed, this means that vibration is occurring in the Z-axis direction, and the magnitude of the acceleration in the Z-axis direction represents the magnitude of the vibration of the car 40 in the Z-axis direction.

[0026] Similarly, the magnitude of the acceleration in the X-axis direction detected by the vibration sensor 110 represents the magnitude of the vibration of the car 40 in the X-axis direction, and the magnitude of the acceleration in the Y-axis direction represents the magnitude of the vibration of the car 40 in the Y-axis direction.

[0027] The communication device 120 includes an antenna and a communication circuit for wirelessly communicating with other devices via the communication network 30. A specific example of another device that communicates with the communication device 120 via the communication network 30 is the evaluation device 20. The communication device 120 transmits vibration data generated by the vibration sensor 110 to the evaluation device 20 via the communication network 30.

[0028] The evaluation device 20 is, for example, a personal computer, and is installed in a workplace where a worker works. The evaluation device 20 includes a processing device 210, which is, for example, a computer such as a CPU, a communication device 220, a display device 230, an input device 240, and a storage device 250. The communication device 220, the display device 230, the input device 240, and the storage device 250 are connected to the processing device 210 via a bus 260 that mediates data exchange.

[0029] The communication device 220 is connected to the communication network 30 by wire or wirelessly. The communication device 220 includes a communication circuit for communicating with other devices via the communication network 30. A specific example of this other device is the measurement device 10. The communication device 220 receives vibration data transmitted from the measurement device 10 via the communication network 30 and transfers the received vibration data to the processing device 210. Note that the evaluation device 20 may be a portable device like the measurement device 10, and may be brought into the car 40 together with the measurement device 10. In this case, the communication device 220 and the communication device 120 may communicate directly by wire or wirelessly without going through the communication network 30.

[0030] The display device 230 includes, for example, a liquid crystal display and its drive circuit. The display device 230 displays various images under the control of the processing device 210. The input device 240 includes, for example, a keyboard with multiple operators such as a numeric keypad and a pointing device such as a mouse, and receives operations by the worker. The input device 240 provides operation content data representing the received operations to the processing device 210. As a result, the operation content of the worker on the input device 240 is transmitted to the processing device 210.

[0031] Although detailed illustration is omitted in FIG. 1, the storage device 250 includes a nonvolatile memory and a volatile memory. The nonvolatile memory includes, for example, a read-only memory (ROM) and a hard disk. Various programs are stored in the nonvolatile memory. The volatile memory includes, for example, a random access memory (RAM). The volatile memory is used by the processing device 210 as a work area when executing various programs.

[0032] The various programs stored in the nonvolatile memory include a kernel program that causes the processing device 210 to implement the OS, and a program PR1 that causes the processing device 210 to execute processing specific to the present invention. The kernel program is not shown in FIG. 1 . In this embodiment, the processing device 210 starts executing the kernel program when the evaluation device 20 is powered on, thereby implementing the OS. The processing device 210, while implementing the OS, reads a program instructed to be executed by an operation on the input device 240 from the nonvolatile memory to the volatile memory, and executes the read program. For example, when an operation on the input device 240 instructs execution of the program PR1, the processing device 210 reads the program PR1 from the nonvolatile memory to the volatile memory, and executes the read program PR1.

[0033] The processing device 210 operating in accordance with the program PR1 functions as the acquisition unit 210a, evaluation unit 210b, and output unit 210c shown in Fig. 1. In other words, each of the acquisition unit 210a, evaluation unit 210b, and output unit 210c shown in Fig. 1 is a software module realized by operating a computer in accordance with the program. The roles of the acquisition unit 210a, evaluation unit 210b, and output unit 210c shown in Fig. 1 are as follows.

[0034] The acquiring unit 210a acquires vibration data representing vibrations in the X-, Y-, and Z-axis directions that occur on the conveyance body when the passenger conveyor is operated at a constant speed, by communicating with the measuring device 10 using the communication device 220. In this embodiment, the acquiring unit 210a acquires vibration data representing vibrations in the X-, Y-, and Z-axis directions that occur on the conveyance body when the passenger conveyor is operated at a constant speed for each of multiple passenger conveyors installed in a building, and stores the vibration data in the volatile memory of the storage device 250 in association with an identifier that identifies the passenger conveyor (for example, a character string representing a serial number assigned to the passenger conveyor).

[0035] The evaluation unit 210b evaluates the magnitude of vibration (maximum vibration value) in each axial direction occurring in each of the plurality of passenger conveyors based on the vibration data acquired for each passenger conveyor by the acquisition unit 210a. In this embodiment, a common target value (e.g., 7 gal, 10 gal, 15 gal, etc.) for the magnitude of vibration in each axial direction is predetermined for the plurality of passenger conveyors. The evaluation unit 210b evaluates the magnitude of vibration in each axial direction occurring in each of the plurality of passenger conveyors by comparing the magnitude of vibration in each axial direction represented by the vibration data with the target value. More specifically, in this embodiment, the evaluation unit 210b outputs the frequency of occurrence of an evaluation value corresponding to the difference between the target value and the magnitude of vibration in each axial direction represented by the vibration data for each of the plurality of passenger conveyors, for each operating direction and for each axial direction. There are two operating directions of an elevator: a direction in which the car 40 ascends along the Z axis (hereinafter referred to as the UP direction) and a direction in which the car 40 descends along the Z axis (hereinafter referred to as the DN direction). In this embodiment, the vibration of the car 40 is measured in both the UP direction and the DN direction when the car 40 is traveling at a constant speed in an unloaded state (a state in which no passengers are on board the car 40).

[0036] The evaluation unit 210b outputs an evaluation value of G1 if the magnitude of vibration represented by the vibration data is 7 gal or less, and outputs an evaluation value of G2 if the magnitude of vibration represented by the vibration data is more than 7 gal but less than 10 gal. Similarly, the evaluation unit 210b outputs an evaluation value of G3 if the magnitude of vibration represented by the vibration data is more than 10 gal but less than 15 gal, an evaluation value of G4 if the magnitude of vibration represented by the vibration data is more than 15 gal but less than 20 gal, and an evaluation value of G5 if the magnitude of vibration represented by the vibration data is more than 20 gal.

[0037] In this embodiment, for example, when the target value is 7 gal, an evaluation value of G1 means that there is no particular problem, and when the evaluation value is G2, G3, G4, or G5, it means that some kind of adjustment is necessary (for example, if the evaluation value for vibrations in the X-axis or Y-axis direction is G2, G3, G4, or G5, it means that the car balance needs to be adjusted). When the target value is 10 gal, an evaluation value of G1 or G2 means that there is no particular problem, and when the evaluation value is G3, G4, or G5, it means that some kind of adjustment is necessary (for example, if the evaluation value for vibrations in the X-axis or Y-axis direction is G3, G4, or G5, it means that the car balance needs to be adjusted). When the target value is 15 gal, an evaluation value of G1, G2, or G3 means that there is no particular problem, and when the evaluation value is G4 or G5, it means that some kind of adjustment is necessary (for example, if the evaluation value for vibrations in the X-axis or Y-axis direction is G4 or G5, it means that the car balance needs to be adjusted).

[0038] The output unit 210c outputs the vibration evaluation results for each of the multiple passenger conveyors, arranging them in the X-axis, Y-axis, and Z-axis directions. More specifically, in this embodiment, the output unit 210c outputs the vibration evaluation results by displaying an image of the report shown in Fig. 3 on the display device 230. As shown in Fig. 3, this report includes a first table A1, a second table A2, a graph A3, an overall evaluation A4, and a pass / fail decision A5.

[0039] Table 1 A1 is a table in which the evaluation values ​​and vibration magnitudes are arranged for each passenger conveyor, each operating direction, and each axial direction. "Car" in Table 1 A1 is the identification information of the elevator. "UP" and "DN" in Table 1 A1 refer to the elevator's operating direction. The output unit 210c may output the evaluation values ​​in Table 1 A1 in different colors. Outputting the evaluation values ​​in different colors means, for example, outputting the evaluation values ​​in different colors by drawing white characters representing the evaluation values ​​against a background colored according to the evaluation value. Specifically, the output unit 210c uses a dark blue background for the evaluation value G1, a light blue background for the evaluation value G2, a yellow background for the evaluation value G3, an orange background for the evaluation value G4, and a red background for the evaluation value G5. This color-coding of the evaluation values ​​allows the user to intuitively grasp the evaluation results through the colors.

[0040] Table 2 A2 is a table in which the frequency of occurrence of each evaluation value across multiple passenger conveyors is arranged by axis direction. The output unit 210c may also output the evaluation values ​​in Table 2 A2 in a color-coded manner, as with Table 1 A1. Furthermore, the output unit 210c may output the frequency of occurrence of evaluation value G1 or G2 and the frequency of occurrence of evaluation values ​​G3, G4, and G5 in a color-coded manner. For example, the characters representing the frequency of occurrence of the former may be output in black, and the characters representing the frequency of occurrence of the latter may be output in red. Graph A3 includes pie charts A31, A32, and A33 representing the distribution of the frequency of occurrence of evaluation values ​​across multiple passenger conveyors for each axis direction, and pie chart A34 representing the distribution of the frequency of occurrence of evaluation values ​​across all three axes. Overall evaluation A4 refers to the evaluation value with the highest frequency of occurrence among the evaluation values ​​for each passenger conveyor, each operating direction, and each axis direction. The pass / fail judgment A5 is a judgment result determined according to the overall evaluation A4, and if the overall evaluation A4 is below the target value, a value indicating pass is set, and if the overall evaluation A4 is above the target value, a value indicating fail is set.

[0041] In the example shown in FIG. 3, the overall evaluation A4 is G2, and the pass / fail evaluation A5 is set to "Passed," which means "passed." Therefore, the worker can understand that the ride comfort of the multiple passenger conveyors as a whole is generally acceptable. Furthermore, from Table 1 A1, the worker can understand the vibration occurrence status for each passenger conveyor, each operating direction, and each axial direction. Furthermore, from Table 2 A2 and Graph A3, the worker can understand the vibration occurrence trend across the multiple passenger conveyors installed at the site. For example, in the example shown in FIG. 3, while the evaluation value for the Z-axis direction is generally G1, the worker can understand that the frequency of G2 is higher than the frequency of G1 for the X-axis and Y-axis directions, and that the frequency of G2 is higher for the Y-axis direction than for the X-axis direction. This means that the frequency of vibration in the Y-axis direction is high, followed by the X-axis direction.

[0042] Next, we will explain a vibration evaluation method using the evaluation system 1. Figure 4 is a flowchart showing the flow of this evaluation method. As shown in Figure 4, this evaluation method includes two steps: an acquisition step SA110 and an evaluation step SA120.

[0043] Acquisition step SA110 is a step in which vibration data is measured for multiple passenger conveyors that are the subject of vibration evaluation. The worker performs the following process for each of the multiple passenger conveyors that are the subject of vibration evaluation. The worker brings measurement device 10 into car 40 and installs measurement device 10 on the floor of car 40. Next, the worker operates car 40 in both the UP and DN directions, measures vibrations while the car is traveling at a constant speed, and transmits vibration data representing the measured vibrations to evaluation device 20 along with identification information for the passenger conveyor and information indicating the direction of travel. When the worker has completed the above process for all of the multiple passenger conveyors that are the subject of vibration evaluation, acquisition step SA110 is complete.

[0044] The evaluation step SA120 is executed after the worker returns to the work site. In the evaluation step SA120, the processing device 210 of the evaluation device 20 functions as the evaluation unit 210b and the output unit 210c. Based on the vibration data acquired for each passenger conveyor, the processing device 210 evaluates the magnitude of vibration in each axial direction of each of the passenger conveyors. The evaluation results are output by displaying the report shown in FIG. 3 on the display device 230. By referring to the overall evaluation A4 in the report shown in FIG. 3, the worker can grasp the overall evaluation of the ride comfort for the entire group of passenger conveyors that are the subject of the vibration evaluation. Furthermore, by referring to the pass / fail judgment A5, the worker can grasp the pass / fail result of the overall ride comfort. Furthermore, the worker can grasp the vibration occurrence status for each passenger conveyor, each operating direction, and each axial direction from Table 1 A1. Furthermore, the worker can grasp the vibration occurrence trend across the entire group of passenger conveyors installed at the work site from Table 2 A2 and Graph A3.

[0045] As shown in Figure 3, when there is a tendency for vibrations in the Y-axis direction to occur frequently, followed by vibrations in the X-axis direction, these vibrations are often caused by a common cause. For this reason, workers can investigate the elevator where the tendency is most pronounced to identify the cause, make adjustments to address it, and if this adjustment improves the vibration, they can also improve the vibration of other elevators that show the same tendency by making similar adjustments.

[0046] As described above, this embodiment makes it possible to comprehensively evaluate the vibrations that occur in each of multiple passenger conveyors installed in a building during operation. Furthermore, this embodiment allows workers to grasp the overall vibration generation trend for multiple passenger conveyors that are the subject of vibration evaluation, thereby narrowing down the wide range of vibration causes and quickly resolving vibration problems.

[0047] The above description is for the purpose of explaining the present invention, and should not be construed as limiting the invention described in the claims or narrowing its scope. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.

[0048] For example, the above embodiment can be modified as follows.

[0049] Although the passenger conveyor in the above embodiment is an elevator, it may also be an escalator. Escalators differ from elevators in that they circulate steps, which are conveying bodies, in a direction along one of two axes perpendicular to the vertical axis and in the vertical axis direction. However, vibrations can occur in the steps due to peeling of the rollers that drive the steps, wear on the sheaves, wear on the sprockets, etc. When applying the present invention to evaluating the vibration of escalator steps, it is sufficient to place measuring device 10 on the steps of an escalator while it is in operation and measure the vibration of the steps.

[0050] Furthermore, the output unit 210c in the above embodiment outputs the evaluation results by displaying the image of the report shown in FIG. 3 on the display device 230. However, the evaluation results may also be output by printing the report or by sending electronic data representing the report to a predetermined destination. For example, when it is necessary to report the evaluation results to the building owner or manager (hereinafter referred to as the customer), the reporting process can be facilitated by submitting a printed copy of the report or electronic data of the report. Furthermore, in the past, graphs showing vibration waveforms or the like were submitted to the customer, making it difficult for the customer to understand the evaluation results. However, the printed copy of the report or the electronic data of the report is visually easy to understand, which has the advantage that the customer can easily grasp the evaluation results.

[0051] If the evaluation device 20 is a portable device, a worker may bring the evaluation device 20 into a building where multiple passenger conveyors to be evaluated are installed and perform the evaluation step SA120 in the building. According to this aspect, a series of operations from the acquisition step SA110 to the evaluation step SA120 is completed in the building, which is the work site, and adjustments based on the evaluation results can be immediately performed in continuation with the work.

[0052] In the above embodiment, the acquisition unit 210a, the evaluation unit 210b, and the output unit 210c are all software modules. However, any one, any two, or all of the acquisition unit 210a, the evaluation unit 210b, and the output unit 210c may be hardware modules such as ASICs. Even if any one, any two, or all of the acquisition unit 210a, the evaluation unit 210b, and the output unit 210c are hardware modules, the same effects as those of the above embodiment can be achieved.

[0053] In the above embodiment, either or both of the measurement device 10 and the evaluation device 20 may be manufactured or provided (transferred, exported, or leased) separately. Similarly, the program PR1 may be manufactured or provided separately. Specific examples of how the program PR1 is provided include downloading it via a telecommunications line, or writing it to a computer-readable recording medium such as a flash ROM and distributing it. Alternatively, only the functions of the evaluation device 20 may be provided by an application service provider via a telecommunications line. [Explanation of symbols]
