Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally, the measurement of the vibration of an elevator car generated during the operation of an elevator is performed for each elevator. However, when a plurality of elevators are installed in the same building, ultimately, a comprehensive evaluation of the vibration is performed for all the elevators installed in the building. This is to ensure that the same riding comfort can be obtained regardless of which elevator is used. The same evaluation is also performed for escalators where the steps are driven in a circulating manner to transport people. Hereinafter, elevators and escalators are collectively referred to as "passenger conveyors". Also, hereinafter, the elevator car and the escalator steps are collectively referred to as "carriers".

[0005] When a plurality of passenger conveyors are installed in the same building, there has been no prior art for comprehensively evaluating the vibrations generated in each carrier during the operation of the plurality of passenger conveyors.

[0006] The present invention aims to provide a system and method that enables the comprehensive evaluation of vibrations generated in each conveyor during the operation of multiple passenger conveyors installed in the same building. [Means for solving the problem]

[0007] The passenger conveyor evaluation system according to the present invention is A measuring device installed on the conveyor body of a passenger conveyor, which measures vibrations generated in the conveyor body when the passenger conveyor is operated at a constant speed, by decomposing them into three mutually orthogonal axial directions including the vertical axis, and generates vibration data representing the measured vibrations in each axial direction, An evaluation device that communicates with the measuring device to acquire vibration data representing the three axial vibrations generated in each conveyor body when each of the multiple passenger conveyors is operated at a constant speed, evaluates the magnitude of each axial vibration generated in each conveyor body of the multiple passenger conveyors based on the acquired vibration data, and outputs the vibration evaluation result for each of the multiple passenger conveyors. Includes.

[0008] This allows the vibration evaluation results for each of the multiple passenger conveyors to be output side-by-side for each of the three axes, making it easy to compare these evaluation results and enabling a comprehensive evaluation of the vibrations generated in each conveyor during the operation of multiple passenger conveyors.

[0009] The evaluation device is By comparing the target values ​​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, a configuration can be made to evaluate the magnitude of vibration in each axial direction that occurs in each of the conveying bodies of the plurality of passenger conveyors.

[0010] This makes it possible to comprehensively evaluate the vibrations generated in each conveyor during the operation of multiple passenger conveyors, based on target values ​​for the magnitude of vibration in each axial direction set for multiple passenger conveyors.

[0011] The evaluation device is 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 multiple passenger conveyors, axially.

[0012] This makes it possible to comprehensively evaluate the vibrations generated in each conveyor during the operation of multiple passenger conveyors through evaluation values.

[0013] The evaluation device is The evaluation values ​​can be output in different colors according to 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 conveyor during the operation of multiple passenger conveyors through the colors assigned to the evaluation values.

[0015] The evaluation device is Table 1 shows the aforementioned evaluation values ​​and vibration magnitudes arranged for each passenger conveyor, each direction of operation, and each axial direction. Table 2 shows the frequency of occurrence of the evaluation value across the entire set of passenger conveyors, arranged axially. And, A graph showing the distribution of the frequency of occurrence of the evaluation value in each axial direction across the entire set of passenger conveyors, and a graph showing the distribution of the frequency of occurrence of the evaluation value across the entire set of three axes. It is possible to output a report that includes at least one of the following:

[0016] This allows for the acquisition of reports evaluating the vibrations generated in each conveyor during the operation of multiple passenger conveyors.

[0017] Furthermore, the evaluation method for a passenger conveyor according to the present invention is: It is installed on the carrier of the passenger conveyor, and when the passenger conveyor is running at a constant speed, the vibration generated on the carrier is decomposed and measured in three axial directions including the vertical axis, and a measuring device that generates vibration data representing the vibration in each measured axial direction is used to measure the vibration generated on the carrier of each of the plurality of passenger conveyors when each of the plurality of passenger conveyors is running at a constant speed, acquire the vibration data, and based on the acquired vibration data, input the vibration data to an evaluation device that evaluates the magnitude of the vibration in each axial direction generated on the carrier of each of the plurality of passenger conveyors and outputs an evaluation result, so as to output the evaluation results of the vibration for each of the plurality of passenger conveyors side by side for each of the three axial directions to the evaluation device, including.

[0018] As a result, the evaluation results of the vibration for each of the plurality of passenger conveyors are output side by side for each of the three axial directions, so that the comparison of these evaluation results becomes easy, and it becomes possible to comprehensively evaluate the vibration generated on each carrier when the plurality of passenger conveyors are running.

Embodiments for Carrying out the Invention

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

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

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

[0023] The measuring device 10 is a portable device that is brought into the cage 40 by a worker performing vibration evaluation work. Once brought into the cage 40 by the worker, the measuring device 10 is installed on the floor of the cage 40. As shown in Figure 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 running at a constant speed, by decomposing them into three mutually orthogonal axial directions, including the vertical axis Z, and generates vibration data representing the vibrations in each measured axial direction. In this embodiment, as shown in Figure 2, of the two axes orthogonal to the vertical axis (hereinafter referred to as the Z axis), which is the up and down direction of the car 40, the axis along the opening and closing direction of the car 40's doors is set as the X axis, and the Y axis is set as an axis orthogonal to the Z axis and the X axis.

[0025] Vibration data represents the time evolution of acceleration in the X, Y, and Z axes. When the elevator is moving at a constant speed, the acceleration in the Z axis direction should be 0. If the acceleration in the Z axis direction detected by the vibration sensor 110 is not 0 when the elevator is moving at a constant speed, it means that vibration is occurring in the Z axis direction, and the magnitude of this acceleration in the Z axis direction represents the magnitude of vibration of the car 40 in that 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 cage 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 cage 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 other devices that communicate 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 workers are employed. The evaluation device 20 includes a processing unit 210, which is 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 unit 210 via a bus 260 that mediates data exchange.

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

[0030] The display device 230 includes, for example, a liquid crystal display and its driving 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 controls such as a numeric keypad and a pointing device such as a mouse, and receives operations from the worker. The input device 240 provides the processing device 210 with operation content data representing the received operations. In this way, the worker's operations on the input device 240 are transmitted to the processing device 210.

[0031] Although not shown in detail in Figure 1, the storage device 250 includes non-volatile memory and volatile memory. The non-volatile memory includes, for example, ROM (Read Only Memory) and a hard disk. Various programs are stored in the non-volatile memory. The volatile memory includes, for example, RAM (Random Access Memory). The volatile memory is used by the processing unit 210 as a work area when executing various programs.

[0032] The various programs stored in the non-volatile memory include a kernel program that enables the processing unit 210 to implement the OS, and a program PR1 that causes the processing unit 210 to execute processing specific to the present invention. Note that the kernel program is not shown in Figure 1. In this embodiment, the processing unit 210 starts executing the kernel program when the evaluation device 20 is powered on, and implements the OS. While the OS is implemented, the processing unit 210 reads a program that it has instructed to execute by an operation on the input device 240 from the non-volatile memory to the volatile memory, and executes the read program. For example, if the input device 240 is instructed to execute program PR1, the processing unit 210 reads program PR1 from the non-volatile memory to the volatile memory, and executes the read program PR1.

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

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

[0035] The evaluation unit 210b evaluates the magnitude of vibration in each axial direction (maximum vibration) generated for each conveyor of the multiple passenger conveyors based on vibration data acquired for each passenger conveyor by the acquisition unit 210a. In this embodiment, common target values ​​(for example, 7 gal, 10 gal, 15 gal, etc.) for the magnitude of vibration in each axial direction are predetermined for the multiple passenger conveyors. The evaluation unit 210b evaluates the magnitude of vibration in each axial direction generated for each conveyor of the multiple 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 evaluation values ​​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 multiple passenger conveyors, for each direction of operation and for each axial direction. There are two directions of operation for the elevator: the direction in which the car 40 is raised along the Z axis (hereinafter referred to as the UP direction) and the direction in which the car 40 is lowered 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 it is operating at a constant speed under no-load conditions (when there are no people in the car 40).

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

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

[0038] The output unit 210c outputs the vibration evaluation results for each of the multiple passenger conveyors, arranged in order of the X, Y, and Z axes. More specifically, in this embodiment, the output unit 210c outputs the vibration evaluation results by displaying the report image shown in Figure 3 on the display device 230. As shown in Figure 3, this report includes Table 1 A1, Table 2 A2, Graph A3, Overall Evaluation A4, and Pass / Fail Judgment A5.

[0039] Table 1A1 is a table that arranges the evaluation value and vibration magnitude for each passenger conveyor, each direction of operation, and each axial direction. In Table 1A1, "Car" is the elevator identification information. In Table 1A1, "UP" and "DN" indicate the direction of operation of the elevator. The output unit 210c may output the evaluation values ​​in Table 1A1 in different colors. Outputting evaluation values ​​in different colors means, for example, drawing the characters representing the evaluation value in white on a background with a color corresponding to the evaluation value. Specifically, the output unit 210c sets the background color to dark blue when the evaluation value is G1, to light blue when the evaluation value is G2, to yellow when the evaluation value is G3, to orange when the evaluation value is G4, and to red when the evaluation value is G5. With this method of outputting evaluation values ​​in different colors, the evaluation results can be intuitively grasped through the colors.

[0040] Table 2A2 is a table that arranges the frequency of occurrence of each evaluation value across multiple passenger conveyors, oriented by axis. Output unit 210c may output the evaluation values ​​in Table 2A2 in the same color as Table 1A1. Output unit 210c may also output the frequency of occurrence of evaluation values ​​G1 or G2 and the frequency of occurrence of evaluation values ​​G3, G4, and G5 in different colors. 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 that show the distribution of the frequency of occurrence of evaluation values ​​for each axis across multiple passenger conveyors, and pie chart A34 that shows the distribution of the frequency of occurrence of evaluation values ​​across all three axes. The overall evaluation A4 refers to the evaluation value with the highest frequency of occurrence among the evaluation values ​​for each passenger conveyor, each direction of operation, and each axis. The pass / fail judgment A5 is determined based on the overall evaluation A4. If the overall evaluation A4 is below the target value, a value indicating a pass is set; if the overall evaluation A4 exceeds the target value, a value indicating a fail is set.

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

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

[0043] Acquisition step SA110 is a step in which vibration data is measured for multiple passenger conveyors that are subject to vibration evaluation. For each of the multiple passenger conveyors that are subject to vibration evaluation, the worker performs the following process: The worker brings the measuring device 10 into the car 40 and places the measuring device 10 on the floor of the car 40. Next, the worker operates the car 40 in both the UP direction and the DN direction, and has the measuring device 10 measure the vibration when the car is operating at a constant speed, and transmits the vibration data representing the measured vibration, along with the identification information of the passenger conveyor and information indicating the direction of operation, to the evaluation device 20. When the worker has completed the above process for all of the multiple passenger conveyors that are subject to vibration evaluation, acquisition step SA110 is completed.

[0044] Evaluation step SA120 is performed after the worker returns to the work area. In evaluation step SA120, the processing unit 210 of the evaluation device 20 functions as an evaluation unit 210b and an output unit 210c, and based on the vibration data acquired for each passenger conveyor, it evaluates the magnitude of vibration in each axial direction that occurred in each conveyor of the multiple passenger conveyors, and outputs the evaluation results by displaying the report shown in Figure 3 on the display device 230. By referring to the overall evaluation A4 in the report shown in Figure 3, the worker can grasp the overall ride comfort evaluation for the multiple passenger conveyors that are the subject of vibration evaluation, and by referring to the pass / fail judgment A5, they can grasp the pass / fail status of the overall ride comfort. In addition, the worker can grasp the vibration occurrence status for each passenger conveyor, each direction of operation, and each axial direction from Table 1 A1. Furthermore, the worker can grasp the vibration occurrence trend across all multiple passenger conveyors installed at the site from Table 2 A2 and Graph A3.

[0045] As shown in Figure 3, when there is a tendency for vibrations to occur frequently in the Y-axis direction, followed by vibrations in the X-axis direction, these vibrations are often caused by a common factor. Therefore, workers can identify the cause by investigating the elevator where this tendency is most pronounced, make adjustments to address it, and if the vibration improves as a result of these adjustments, apply the same adjustments to other elevators exhibiting a similar tendency to improve their vibration.

[0046] As described above, this embodiment makes it possible to comprehensively evaluate the vibrations generated in each conveyor during the operation of multiple passenger conveyors installed in a building. Furthermore, this embodiment allows workers to grasp the overall vibration trends of the multiple passenger conveyors being evaluated, 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 interpreted as limiting or restricting the scope of the invention described in the claims. Furthermore, it goes without saying that the configuration of each part of the present invention is not limited to the above embodiments and can be modified in various ways within the technical scope described in the claims.

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

[0049] In the above embodiment, the passenger conveyor was an elevator, but it may also be an escalator. An escalator differs from an elevator in that it circulates the steps, which are the conveying bodies, in a direction along one of two axes perpendicular to the vertical axis and in the direction of the vertical axis. However, vibrations can occur in the steps due to peeling of the rollers that drive the steps, wear of the sheaves, wear of the sprockets, etc. When applying the present invention to evaluate the vibration of steps in an escalator, the measuring device 10 can be placed on the steps of the escalator in operation and the vibration of the steps can be measured.

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

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

[0052] In the above embodiment, the acquisition unit 210a, the evaluation unit 210b, and the output unit 210c were 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 in the above embodiment will be achieved.

[0053] In the above embodiment, either the measuring device 10 or the evaluation device 20, or both, may be manufactured or provided (transferred, exported, or leased) as standalone units. Similarly, program PR1 may be manufactured or provided as standalone units. Specific methods of providing program PR1 include downloading it via a telecommunications line, or writing program PR1 to a computer-readable recording medium such as 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]
