In addition, this invention is not limited by the following embodiment. In addition, the components in the following embodiments include components that can be easily conceived by those skilled in the art or that are substantially the same.

[实施方式1][Embodiment 1]

(自动扶梯的结构例)(Example of structure of escalator)

图1是示出实施方式1所涉及的自动扶梯1的简要结构的图。如图1所示,自动扶梯1具备多个梯级100、1对栏杆板101a、101b、扶手带102a、102b、乘降口103a、103b。1 : is a figure which shows the schematic structure of the escalator 1 which concerns on Embodiment 1. FIG. As shown in Fig. 1 , the escalator 1 includes a plurality of steps 100, a pair of handrails 101a, 101b, handrails 102a, 102b, and entrances 103a, 103b.

多个梯级100连结成环状。各个梯级100是当自动扶梯1的利用者R搭乘自动扶梯1时作为落脚点的部件,且由未图示的桁架带有设定的倾斜角度地支承。未图示的驱动马达使内设于桁架的上下端部的链轮105a、105b旋转,由此,各个梯级100作为与乘降口103a、103b之间的台阶状的搭乘台而循环移动。即、各个梯级100一边在乘降口103a与乘降口103b之间环行一边移动。各个梯级100例如由铸铝形成。The plurality of steps 100 are connected in a ring shape. Each step 100 is a member that serves as a foothold when the user R of the escalator 1 gets on the escalator 1, and is supported by a truss (not shown) with a set inclination angle. A drive motor (not shown) rotates the sprockets 105a and 105b built in the upper and lower ends of the truss, whereby each of the steps 100 circulates as a stepped platform between the entrances 103a and 103b. That is, each step 100 moves while circulating between the entrance 103a and the entrance 103b. Each step 100 is formed of, for example, cast aluminum.

在链轮105a设置有脉冲发生器106。脉冲发生器106以与梯级100的移动速度相应的预定间隔产生脉冲。通过对上述脉冲数进行计数,能够计算各个梯级100的移动距离。A pulse generator 106 is provided on the sprocket 105a. The pulse generator 106 generates pulses at predetermined intervals corresponding to the moving speed of the step 100 . The moving distance of each step 100 can be calculated by counting the above-mentioned number of pulses.

栏杆板101a、101b在自动扶梯1的宽度方向上设置在多个梯级100的两侧。栏杆板101a、101b夹着多个梯级100对置设置。栏杆板101a、101b例如由透明的玻璃或丙烯等形成。The handrails 101 a and 101 b are provided on both sides of the plurality of steps 100 in the width direction of the escalator 1 . The railing boards 101a and 101b are provided opposite to each other with a plurality of steps 100 interposed therebetween. The railing boards 101a and 101b are formed of, for example, transparent glass, acrylic, or the like.

扶手带102a、102b是供利用者R用手抓住的部件。扶手带102a、102b是环状的带、且以能够移动的方式卷绕在栏杆板101a、101b的各自的周缘部。扶手带102a、102b借助驱动马达而与各个梯级100的移动同步地移动。扶手带102a、102b例如由橡胶等形成。The handrails 102a and 102b are members for the user R to grasp by hand. The handrail belts 102a and 102b are endless belts, and are movably wound around the respective peripheral edge portions of the handrail boards 101a and 101b. The handrails 102a, 102b are moved in synchronization with the movement of the respective steps 100 by means of drive motors. The handrails 102a and 102b are formed of, for example, rubber or the like.

乘降口103a、103b分别具备乘降板104a、104b。乘降板104a、104b是利用者R相对于自动扶梯1乘降时的落脚点。并且,乘降板104a、104b设置成能够拆卸。在乘降板104a、104b的下方收纳有驱动马达以及折叠后的梯级100等。The entrances and exits 103a and 103b are provided with entrance and exit plates 104a and 104b, respectively. The boarding and landing boards 104a and 104b are footholds when the user R gets on and off the escalator 1 . In addition, the riding boards 104a and 104b are provided so as to be detachable. The drive motor and the folded steps 100 and the like are accommodated below the landing boards 104a and 104b.

(梯级驱动部的结构例)(Configuration example of step drive unit)

其次,使用图2对驱动梯级100的梯级驱动部200的结构进行说明。图2是示出实施方式1所涉及的梯级100周边的简要结构以及自动扶梯诊断装置10的图。Next, the structure of the step driving part 200 which drives the step 100 is demonstrated using FIG. 2. FIG. FIG. 2 is a diagram showing a schematic configuration around the step 100 and the escalator diagnostic apparatus 10 according to the first embodiment.

如图2所示,梯级100由梯级支承部250从下方支承。由此,梯级100作为台阶状的搭乘台发挥功能。As shown in FIG. 2 , the step 100 is supported from below by the step support portion 250 . Thereby, the step 100 functions as a stepped boarding platform.

在梯级100,在导轨300上设置有梯级驱动部200。梯级驱动部200具备梯级前车轮220、梯级后车轮230、以及梯级链240。The step 100 is provided with the step driving unit 200 on the guide rail 300 . The step drive unit 200 includes step front wheels 220 , step rear wheels 230 , and step chains 240 .

导轨300在未图示的桁架上以沿着桁架的倾斜角度的方式设置,在梯级100的两侧形成1对。导轨300具备板状的部件以及屹立在该部件的短边方向两侧的1对侧壁。导轨300所具备的板状的部件构成导轨300的主面。即、导轨300的上表面(后述的梯级前车轮220等接触的面)和下表面是导轨300的主面。The guide rails 300 are provided on a truss (not shown) so as to follow the inclination angle of the truss, and a pair is formed on both sides of the step 100 . The guide rail 300 includes a plate-shaped member and a pair of side walls standing on both sides in the transversal direction of the member. The plate-shaped member included in the guide rail 300 constitutes the main surface of the guide rail 300 . That is, the upper surface of the guide rail 300 (a surface with which the step front wheels 220 and the like, which will be described later, come into contact) and the lower surface are the main surfaces of the guide rail 300 .

梯级前车轮220例如是由车轴221连接的2对车轮。这2对梯级前车轮220以与梯级100两侧的导轨300分别接触的方式设置。梯级后车轮230例如是由车轴231连接的1对车轮。这1对梯级后车轮230位于梯级前车轮220的内侧(靠近梯级100)、且以与梯级100两侧的导轨300分别接触的方式设置。主要利用2对梯级前车轮220以及1对梯级后车轮230构成梯级车轮。The step front wheel 220 is, for example, two pairs of wheels connected by an axle 221 . The two pairs of step front wheels 220 are provided in contact with the guide rails 300 on both sides of the step 100, respectively. The step rear wheel 230 is, for example, a pair of wheels connected by an axle 231 . The pair of step rear wheels 230 are located inside (close to the step 100 ) of the step front wheels 220 , and are arranged to be in contact with the guide rails 300 on both sides of the step 100 . The step wheels are mainly composed of two pairs of step front wheels 220 and one pair of step rear wheels 230 .

梯级链240例如由将2对梯级前车轮220彼此连结的1对链、以及将2对梯级前车轮220与1对梯级后车轮230连结的1对链构成。1对梯级链240连接于2对梯级前车轮220的轮轴由此将这2对梯级前车轮220彼此连结。另1对梯级链240连接于2对梯级前车轮220以及1对梯级后车轮230的轮轴,由此将该梯级前车轮220与梯级后车轮230连结。The step chain 240 includes, for example, a pair of chains that connect two pairs of front step wheels 220 to each other, and a pair of chains that connect two pairs of front step wheels 220 and a pair of rear step wheels 230 . One pair of step chains 240 is connected to the axles of the two pairs of step front wheels 220, thereby connecting the two pairs of step front wheels 220 to each other. The other pair of step chains 240 is connected to the axles of the two pairs of step front wheels 220 and the one pair of step rear wheels 230 , thereby connecting the step front wheels 220 and the step rear wheels 230 .

在梯级驱动部200中,利用未图示的驱动马达使梯级链240进行进给动作。由此,2对梯级前车轮220和1对梯级后车轮230沿着导轨300行进,从而使梯级100沿着桁架的倾斜角度升降。另外,导轨300、梯级前车轮220、梯级后车轮230、以及梯级链240的个数或配置能够进行各种变更,并不限于上述的说明中的结构。In the step drive unit 200, the step chain 240 is fed by a drive motor (not shown). Thereby, the two pairs of step front wheels 220 and the one pair of step rear wheels 230 travel along the guide rails 300 , so that the steps 100 are raised and lowered along the inclination angle of the truss. In addition, the number and arrangement of the guide rails 300 , the step front wheels 220 , the step rear wheels 230 , and the step chains 240 can be variously changed, and are not limited to the structures described above.

在导轨300的上表面设置有形变检测部40。形变检测部40包含检测因梯级车轮通过而导致的导轨300的形变的多个形变传感器40a。具体地说,形变传感器40a针对1个导轨300例如设置在梯级前车轮220所通过的轨道220t上以及梯级后车轮230所通过的轨道230t上这2处。即、形变传感器40a在梯级100两侧的导轨300上各设置1对,总计设置有2对。形变传感器40a的详细结构后述。A deformation detection unit 40 is provided on the upper surface of the guide rail 300 . The deformation detection unit 40 includes a plurality of deformation sensors 40 a that detect deformation of the guide rail 300 due to the passage of the step wheels. Specifically, the deformation sensor 40a is provided, for example, at two places on one guide rail 300, on the rail 220t on which the step front wheel 220 passes and on the rail 230t on which the step rear wheel 230 passes. That is, one pair of the strain sensors 40a is provided on each of the guide rails 300 on both sides of the step 100, and a total of two pairs are provided. The detailed structure of the strain sensor 40a will be described later.

(自动扶梯诊断装置的结构例)(Configuration example of escalator diagnostic device)

其次,继续使用图2对自动扶梯诊断装置10的结构进行说明。Next, the configuration of the escalator diagnostic apparatus 10 will be described with continued use of FIG. 2 .

在自动扶梯1中,为了确保高安全性,定期地进行保养检修。保养检修例如在自动扶梯1所被设置的设施的开始营业前或结束营业后等没有利用者R时通过手动地或者定时的自动运转等进行。自动扶梯1构成为能够在通常运行时的运行模式和保养检修时的检修模式之间切换状态。在保养检修时,以检修模式使自动扶梯1工作,在没有利用者R的状态下取得来自形变检测部40的输出信号。In the escalator 1, in order to ensure high safety, maintenance and inspection are performed regularly. The maintenance and inspection are performed by manual or timed automatic operation or the like when there is no user R, such as before or after the facility in which the escalator 1 is installed, for example, when there is no user R. The escalator 1 is configured so that the state can be switched between an operation mode during normal operation and an inspection mode during maintenance inspection. At the time of maintenance and inspection, the escalator 1 is operated in the inspection mode, and the output signal from the deformation detection unit 40 is acquired in a state where there is no user R.

如图2所示,自动扶梯诊断装置10与形变检测部40电连接,具备控制部20以及存储部30。自动扶梯诊断装置10所具备的各部分经由任意的通信线路以能够通信的方式连接。As shown in FIG. 2 , the escalator diagnostic apparatus 10 is electrically connected to the strain detection unit 40 , and includes a control unit 20 and a storage unit 30 . Each part with which the escalator diagnostic apparatus 10 is equipped is connected so that communication is possible via an arbitrary communication line.

存储部30例如是RAM(Random Access Memory,随机访问存储器)、ROM(Read OnlyMemory,只读存储器)等存储器装置、硬盘之类的固定盘片装置、软盘、或者光盘等。在存储部30收纳有设置时检修模式数据31。设置时检修模式数据31是在自动扶梯1的设置时以检修模式使自动扶梯1工作,在没有利用者R的状态下从形变检测部40取得的输出信号的数据。设置时检修模式数据31是相对于后述的保养检修时的输出信号的基准值。The storage unit 30 is, for example, a memory device such as a RAM (Random Access Memory) or a ROM (Read Only Memory), a fixed disk device such as a hard disk, a floppy disk, or an optical disk. The installation inspection mode data 31 is stored in the storage unit 30 . The inspection mode data 31 at the time of installation is data of an output signal obtained from the deformation detection unit 40 when the escalator 1 is operated in the inspection mode at the time of installation of the escalator 1 and the user R is not present. The inspection mode data 31 at the time of installation is a reference value for an output signal at the time of maintenance and inspection to be described later.

控制部20具备微型计算机以及驱动电路,微型计算机具有由通常形式的双向共用总线相互连结的CPU(中央运算处理装置)、预先存储预定的控制程序等的ROM(Read OnlyMemory,只读存储器)、暂时存储CPU的运算结果的RAM(Random Access Memory,随机访问存储器)、备份RAM、以及输入输出端口装置。控制部20在功能概念上包括输入部21、信号处理部22、以及外部输出部23。The control unit 20 includes a microcomputer and a drive circuit. The microcomputer includes a CPU (Central Processing Unit) interconnected by a common bidirectional shared bus, a ROM (Read Only Memory) that stores a predetermined control program in advance, and a temporary memory. A RAM (Random Access Memory) for storing operation results of the CPU, a backup RAM, and an input/output port device. The control unit 20 functionally includes an input unit 21 , a signal processing unit 22 , and an external output unit 23 .

输入部21取得来自形变检测部40的输出信号。The input unit 21 acquires the output signal from the strain detection unit 40 .

信号处理部22在保养检修时若取得来自形变检测部40的输出信号则对上述输出信号进行处理,判定输出信号是否异常。具体地说,信号处理部22对收纳于存储部30的设置时检修模式数据31(基准值)和在保养检修时取得的输出信号的数据进行比较,判定保养检修时的输出信号是否异常。当保养检修时的输出信号异常的情况下,意味着在自动扶梯1的梯级驱动部200产生某种异常。When the signal processing unit 22 acquires the output signal from the deformation detection unit 40 during maintenance and inspection, the signal processing unit 22 processes the output signal, and determines whether the output signal is abnormal or not. Specifically, the signal processing unit 22 compares the installation inspection mode data 31 (reference value) stored in the storage unit 30 with the data of the output signal acquired at the time of maintenance, and determines whether the output signal at the time of maintenance is abnormal. When the output signal at the time of maintenance and inspection is abnormal, it means that some kind of abnormality has occurred in the step driving part 200 of the escalator 1 .

作为异常的检测例,例如存在如下的情况:在梯级前车轮220以及梯级后车轮230的任意一个或者多个车轮产生从预定的轨道脱离的横向偏移。在该情况下,梯级前车轮220或者梯级后车轮230与形变检测部40接触的部分成为一部分。因此,即便梯级前车轮220或者梯级后车轮230通过形变检测部40,形变检测部40的形变量也比通常时小,输出信号也变小。作为异常检测的其他例,例如存在如下的情况:梯级前车轮220以及梯级后车轮230的任意一个或者多个车轮破损。在该情况下,来自形变检测部40的输出信号变小、或者完全检测不到。当在破损的车轮产生突起那样的缺陷时,也有可能产生输出信号突发性地变大的情况。As an example of abnormality detection, for example, there is a case in which lateral deviation occurs in any one or a plurality of wheels of the step front wheel 220 and the step rear wheel 230 that deviates from a predetermined track. In this case, the portion of the step front wheel 220 or the step rear wheel 230 that is in contact with the deformation detection unit 40 becomes a part. Therefore, even if the step front wheel 220 or the step rear wheel 230 passes through the deformation detection unit 40, the deformation amount of the deformation detection unit 40 is smaller than that in the normal case, and the output signal is also smaller. As another example of abnormality detection, for example, there is a case where any one or a plurality of wheels of the step front wheel 220 and the step rear wheel 230 are damaged. In this case, the output signal from the strain detection unit 40 becomes small or cannot be detected at all. When a defect such as a protrusion occurs in a damaged wheel, there is a possibility that the output signal suddenly increases.

即、当正常的车轮在形变检测部40上通过时,形变检测部40的输出信号以大致恒定的强度推移。车轮的异常作为从恒定强度突出的凸峰值、或者凹峰值被检测到。当在这样的峰值与基准值上存在预先设定的阈值以上的偏离的情况下,判定为保养检修时的输出信号异常。阈值例如根据自动扶梯1的规格值等求出。信号处理部22当保养检修时的输出信号异常的情况下判定为在自动扶梯1的梯级驱动部200产生某种异常。That is, when a normal wheel passes over the deformation detection unit 40, the output signal of the deformation detection unit 40 changes with a substantially constant intensity. The abnormality of the wheel is detected as a convex peak or a concave peak protruding from a constant intensity. When such a peak value deviates from the reference value by a predetermined threshold value or more, it is determined that the output signal at the time of maintenance is abnormal. The threshold value is calculated|required based on the specification value of the escalator 1, etc., for example. The signal processing unit 22 determines that some kind of abnormality has occurred in the step driving unit 200 of the escalator 1 when the output signal at the time of maintenance is abnormal.

外部输出部23当判定为来自形变检测部40的输出信号异常的情况下将在梯级驱动部200产生异常这一情况输出至外部。朝外部的输出例如为针对监视担当人员的警报的发报或者广播、针对未图示的监视中心的警告显示、针对保养担当人员的邮件发送等。When it is determined that the output signal from the strain detection unit 40 is abnormal, the external output unit 23 outputs to the outside that an abnormality has occurred in the step driving unit 200 . The output to the outside is, for example, notification or broadcast of an alarm to a person in charge of monitoring, a warning display to a monitoring center (not shown), mail transmission to a person in charge of maintenance, and the like.

(形变传感器的结构例)(Configuration example of strain sensor)

此处,使用图3,对形变检测部40所包含的形变传感器40a的详细结构进行说明。图3是示出实施方式1所涉及的形变传感器40a的简要结构的图。Here, the detailed structure of the strain sensor 40a included in the strain detection unit 40 will be described with reference to FIG. 3 . FIG. 3 is a diagram showing a schematic configuration of the strain sensor 40 a according to the first embodiment.

如图3所示,形变传感器40a是金属形变测量仪,具备:一边呈之字状地蜿蜒一边沿一个方向延伸的测量仪40G;支承测量仪40G的基座40B;以及从测量仪40G引出输出信号的导线40L。将测量仪40G所延伸的方向的长度称为测量仪长L、将与测量仪40G延伸的方向正交的方向的长度称为测量仪宽W。测量仪40G通过被施加载荷等而自身变形来产生与形变量相应的预定的电压。As shown in FIG. 3 , the strain sensor 40a is a metal strain gauge, and includes: a gauge 40G extending in one direction while meandering in a zigzag shape; a base 40B supporting the gauge 40G; Wire 40L for the output signal. The length in the direction in which the measuring instrument 40G extends is referred to as the instrument length L, and the length in the direction orthogonal to the direction in which the instrument 40G extends is referred to as the instrument width W. The measuring instrument 40G deforms itself by being applied with a load or the like to generate a predetermined voltage according to the amount of deformation.

若使自动扶梯1工作,则梯级前车轮220和梯级后车轮230沿着导轨300行进。此时,在导轨300产生预定量的形变。若梯级前车轮220和梯级后车轮230分别在形变传感器40a上通过,则在导轨300产生的形变传递至形变传感器40a,预定量的形变被作为输出信号检测。When the escalator 1 is operated, the step front wheel 220 and the step rear wheel 230 travel along the guide rail 300 . At this time, a predetermined amount of deformation is generated in the guide rail 300 . When the step front wheel 220 and the step rear wheel 230 respectively pass over the deformation sensor 40a, the deformation generated in the guide rail 300 is transmitted to the deformation sensor 40a, and a predetermined amount of deformation is detected as an output signal.

另外,形变传感器40a例如也可以是使用了压电元件的半导体体形变测量仪等。In addition, the strain sensor 40a may be, for example, a semiconductor body strain gauge or the like using a piezoelectric element.

并且,形变传感器40a设置于导轨300的上表面,但也可以设置于下表面。由此,能够抑制因梯级车轮等而导致形变传感器40a损伤这一情况。这样,形变传感器40a(形变检测部40)可以设置于导轨300的主面、即上表面或者下表面的任一个。但是,因梯级车轮等而产生的导轨300的形变量在导轨300的上表面较大。因此,通过形变传感器40a设置于导轨300的上表面,输出信号变大,能够检测更微小的形变。In addition, the strain sensor 40a is provided on the upper surface of the guide rail 300, but may be provided on the lower surface. As a result, it is possible to suppress damage to the strain sensor 40a due to the stepped wheel or the like. In this way, the strain sensor 40a (the strain detector 40 ) may be provided on the main surface of the guide rail 300 , that is, on either the upper surface or the lower surface. However, the amount of deformation of the guide rail 300 due to step wheels and the like is large on the upper surface of the guide rail 300 . Therefore, when the strain sensor 40a is provided on the upper surface of the guide rail 300, the output signal becomes larger, and the finer strain can be detected.

(自动扶梯诊断处理的例子)(Example of escalator diagnostic processing)

其次,使用图4对自动扶梯诊断装置10的诊断处理进行说明。图4是示出实施方式1所涉及的自动扶梯诊断处理的顺序的一例的流程图。Next, the diagnostic process of the escalator diagnostic apparatus 10 is demonstrated using FIG. 4. FIG. 4 is a flowchart showing an example of the procedure of the escalator diagnosis process according to the first embodiment.

在步骤S11中,自动扶梯诊断装置10的控制部20所具备的输入部21取得在自动扶梯1的设置时检测到的来自形变检测部40的输出信号,并作为设置时检修模式数据31存储于存储部30。In step S11, the input unit 21 included in the control unit 20 of the escalator diagnostic apparatus 10 acquires the output signal from the deformation detection unit 40 detected at the time of installation of the escalator 1, and stores it as the inspection mode data 31 at the time of installation in storage unit 30 .

在步骤S12中,控制部20的输入部21取得在自动扶梯1的保养检修时检测到的来自形变检测部40的输出信号。In step S12, the input part 21 of the control part 20 acquires the output signal from the deformation|transformation detection part 40 which was detected at the time of the maintenance and inspection of the escalator 1.

在步骤S13中,控制部20的信号处理部22将自动扶梯1的设置时的输出信号与保养检修时的输出信号进行比较。In step S13, the signal processing unit 22 of the control unit 20 compares the output signal at the time of installation of the escalator 1 with the output signal at the time of maintenance.

在步骤S14中,若2个输出信号的偏离小于阈值(否),则返回步骤S12,反复进行以下的流程。在步骤S14中,若2个输出信号的偏离为阈值以上(是),则在步骤15中,控制部20的外部输出部23将自动扶梯1的异常输出至外部。In step S14, if the deviation of the two output signals is smaller than the threshold value (NO), the process returns to step S12, and the following flow is repeated. In step S14, when the deviation of the two output signals is equal to or greater than the threshold value (Yes), in step S15, the external output unit 23 of the control unit 20 outputs the abnormality of the escalator 1 to the outside.

综上,自动扶梯诊断装置10的诊断处理结束。当自动扶梯1的异常被输出至外部的情况下,例如作业者将自动扶梯1的乘降板104a、104b卸下,目视确认各部状态以及动作状态,进行必要的维修作业。In conclusion, the diagnostic processing of the escalator diagnostic apparatus 10 is completed. When the abnormality of the escalator 1 is outputted to the outside, for example, the operator removes the landing boards 104a and 104b of the escalator 1, visually checks the state and operation state of each part, and performs necessary maintenance work.

在以往的自动扶梯中,在保养检修时,作业者必须将自动扶梯的乘降板卸下,目视确认各部状态以及动作状态。为了确保自动扶梯的安全性,保养检修是日常进行的,作业者的负担大。并且,目视的确认耗费时间,自动扶梯的运行时间减少。In the conventional escalator, at the time of maintenance and inspection, the operator had to remove the landing board of the escalator, and visually check the state and operation state of each part. In order to ensure the safety of the escalator, maintenance and inspection are carried out on a daily basis, and the burden on the operator is large. In addition, the visual confirmation takes time, and the running time of the escalator is reduced.

根据实施方式1的自动扶梯诊断装置10,即便不将乘降板104a、104b卸下而进行确认,也能够检测自动扶梯1内部的梯级前车轮220以及梯级后车轮230的异常。由此,能够实现保养检修作业的省力化以及时间削减。并且,能够进行早期的异常检测。According to the escalator diagnostic apparatus 10 of Embodiment 1, even if it confirms without removing the landing board 104a, 104b, the abnormality of the step front wheel 220 and the step rear wheel 230 inside the escalator 1 can be detected. Thereby, labor saving and time reduction of maintenance and inspection work can be achieved. Also, early abnormality detection can be performed.

另外,在上述的说明中,在自动扶梯1设置时取得来自形变检测部40的输出信号,并将其作为针对保养检修时的输出信号的基准值。但是,代替自动扶梯1设置时的输出信号,也可以将具有相同规格的自动扶梯的输出信号例如基于规格值进行一般化,并将该值作为基准值。或者,也可以将保养检修时的输出信号中的稳定值或者平均值作为基准值。这点对于以下的各种变形例也同样。In addition, in the above-mentioned description, the output signal from the deformation|transformation detection part 40 was acquired when the escalator 1 was installed, and it was set as a reference value for the output signal at the time of maintenance. However, instead of the output signal when the escalator 1 is installed, the output signal of the escalator having the same specification may be generalized, for example, based on the specification value, and this value may be used as the reference value. Alternatively, a stable value or an average value of output signals during maintenance and inspection may be used as a reference value. This also applies to the following various modifications.

(变形例1)(Variation 1)

其次,对实施方式1的变形例1进行说明。变形例1的自动扶梯诊断装置的形变检测部的结构与实施方式1的自动扶梯诊断装置10不同。以下,使用图5,仅对与实施方式1的自动扶梯诊断装置10的不同点进行说明。图5是示出实施方式1的变形例1所涉及的梯级100周边的简要结构以及自动扶梯诊断装置10的图。Next, Modification 1 of Embodiment 1 will be described. The structure of the deformation|transformation detection part of the escalator diagnostic apparatus of the modification 1 differs from the escalator diagnostic apparatus 10 of Embodiment 1 in structure. Hereinafter, only differences from the escalator diagnostic apparatus 10 of the first embodiment will be described using FIG. 5 . 5 : is a figure which shows the schematic structure of the step 100 vicinity and the escalator diagnostic apparatus 10 which concern on the modification 1 of Embodiment 1. FIG.

如图5所示,变形例1的形变检测部41所包含的多个形变传感器40a例如设置成在导轨300的两端部附近和由导轨300的两端部夹持的区域等间隔地配置。即、形变传感器40a设置在梯级前车轮220所通过的轨道220t上的多个部位。并且,形变传感器40a设置在梯级后车轮230所通过的轨道230t上的多个部位。这样,在变形例1的自动扶梯诊断装置10中,多个形变传感器40a遍及导轨300的整个区域以散布的方式配置。As shown in FIG. 5 , the plurality of strain sensors 40 a included in the strain detection unit 41 according to Modification 1 are disposed at equal intervals, for example, in the vicinity of both ends of the guide rail 300 and a region sandwiched by both ends of the guide rail 300 . That is, the deformation sensors 40a are provided at a plurality of locations on the rail 220t through which the step front wheels 220 pass. In addition, the deformation sensors 40a are provided at a plurality of locations on the rail 230t through which the rear wheel 230 passes. In this way, in the escalator diagnostic apparatus 10 of Modification 1, the plurality of strain sensors 40a are arranged so as to be scattered over the entire area of the guide rail 300 .

根据变形例1的自动扶梯诊断装置10,在1个轨道220t(或者轨道230t)上设置有多个形变传感器40a,异常检测的精度更高。According to the escalator diagnostic apparatus 10 of Modification 1, the plurality of strain sensors 40a are provided on one rail 220t (or rail 230t), and the accuracy of abnormality detection is higher.

(变形例2)(Variation 2)

其次,对实施方式1的变形例2进行说明。变形例2的自动扶梯诊断装置的形变检测部的结构与实施方式1的自动扶梯诊断装置10不同。以下,使用图6,仅对与实施方式1的自动扶梯诊断装置10的不同点进行说明。图6是示出实施方式1的变形例2所涉及的梯级100周边的简要结构以及自动扶梯诊断装置10的图。Next, Modification 2 of Embodiment 1 will be described. The structure of the deformation|transformation detection part of the escalator diagnostic apparatus of the modification 2 differs from the escalator diagnostic apparatus 10 of Embodiment 1. FIG. Hereinafter, only differences from the escalator diagnostic apparatus 10 of the first embodiment will be described with reference to FIG. 6 . FIG. 6 is a diagram showing a schematic configuration of a step 100 and its vicinity and the escalator diagnostic apparatus 10 according to Modification 2 of Embodiment 1. FIG.

如图6所示,变形例2的形变检测部42所包含的多个形变传感器42a具有比实施方式1的形变传感器40a长的测量仪长。形变传感器42a的测量仪长例如为梯级前车轮220(或者梯级后车轮230)旋转1周时所前进的距离Ro以上。但是,并不限于图6的例子,也可以将多个实施方式1的形变传感器40a连结起来而使得整体的测量仪长为距离Ro以上。As shown in FIG. 6 , the plurality of strain sensors 42 a included in the strain detection unit 42 of the second modification have a gauge length that is longer than the strain sensor 40 a of the first embodiment. The gauge length of the strain sensor 42a is, for example, equal to or greater than the distance Ro traveled when the step front wheel 220 (or the step rear wheel 230) makes one rotation. However, it is not limited to the example of FIG. 6 , and a plurality of strain sensors 40 a of the first embodiment may be connected so that the overall measuring instrument length is equal to or longer than the distance Ro.

根据变形例2的自动扶梯诊断装置10,由于使形变传感器42a的测量仪长为梯级前车轮220(或者梯级后车轮230)旋转1周时所前进的距离Ro以上,因此,能够检测梯级前车轮220(或者梯级后车轮230)与导轨300接触的接触面整体的异常。由此,例如即便在梯级前车轮220(或者梯级后车轮230)的一部分缺损那样的情况下等也能够检测异常。即、异常检测的精度更高。According to the escalator diagnostic apparatus 10 of the modification 2, since the gauge length of the strain sensor 42a is set to be equal to or more than the distance Ro traveled when the step front wheel 220 (or the step rear wheel 230) makes one rotation, it is possible to detect the step front wheel 220 (or the step rear wheel 230 ) is abnormal in the entire contact surface with the guide rail 300 . This makes it possible to detect an abnormality, for example, even when a part of the step front wheel 220 (or the step rear wheel 230 ) is broken. That is, the accuracy of abnormality detection is higher.

(变形例3)(Variation 3)

其次,对实施方式1的变形例3进行说明。变形例3的自动扶梯诊断装置在具备检测梯级100的位置的位置检测部这点上与实施方式1的自动扶梯诊断装置10不同。以下,使用图7~图9,仅对与实施方式1的自动扶梯诊断装置10的不同点进行说明。图7是示出实施方式1的变形例3所涉及的基准梯级100s周边的简要结构以及自动扶梯诊断装置10的图。Next, Modification 3 of Embodiment 1 will be described. The escalator diagnostic apparatus of Modification 3 differs from the escalator diagnostic apparatus 10 of Embodiment 1 in that it includes a position detection unit that detects the position of the step 100 . Hereinafter, only differences from the escalator diagnostic apparatus 10 according to Embodiment 1 will be described using FIGS. 7 to 9 . 7 : is a figure which shows the schematic structure of the reference|standard step 100s periphery and the escalator diagnostic apparatus 10 which concern on the modification 3 of Embodiment 1. FIG.

变形例3的位置检测部也能够应用于上述的实施方式1以及变形例1、2的任一个自动扶梯诊断装置10。在图7中,示出在实施方式1的自动扶梯诊断装置10应用位置检测部50的情况。如图7所示,在变形例3的自动扶梯1中,设置有在梯级支承部250具备基准梯级检测部51的基准梯级100s。变形例3的自动扶梯诊断装置10根据基准梯级检测部51的检测信号和来自设置于上述的链轮105a(参照图1)的脉冲发生器106的脉冲信号来确定发生异常的梯级100的位置。发生异常的梯级100的位置信息例如作为异常梯级位置信息50i被收纳于存储部30。包含基准梯级检测部51以及脉冲发生器106的位置检测部以及形变检测部40连接于变形例3的自动扶梯诊断装置10。The position detection unit of Modification 3 can also be applied to the escalator diagnostic apparatus 10 of Embodiment 1 and Modifications 1 and 2 described above. In FIG. 7, the case where the position detection part 50 is applied to the escalator diagnostic apparatus 10 of Embodiment 1 is shown. As shown in FIG. 7, in the escalator 1 of the modification 3, 100 s of reference steps provided with the reference step detection part 51 in the step support part 250 are provided. The escalator diagnostic apparatus 10 of Modification 3 specifies the position of the abnormal step 100 based on the detection signal of the reference step detection unit 51 and the pulse signal from the pulse generator 106 provided in the above-described sprocket 105a (see FIG. 1 ). The position information of the abnormal step 100 is stored in the storage unit 30 as abnormal step position information 50i, for example. The position detection unit and the deformation detection unit 40 including the reference step detection unit 51 and the pulse generator 106 are connected to the escalator diagnostic apparatus 10 of the third modification.

图8是示出实施方式1的变形例3所涉及的位置检测部50的简要结构的图。如图8所示,位置检测部50具备基准梯级100s的基准梯级检测部51、基准点开关51a、开关支承部51b、以及脉冲发生器106。FIG. 8 is a diagram showing a schematic configuration of a position detection unit 50 according to Modification 3 of Embodiment 1. As shown in FIG. As shown in FIG. 8 , the position detection unit 50 includes a reference step detection unit 51 of a reference step 100 s , a reference point switch 51 a , a switch support unit 51 b , and a pulse generator 106 .

基准梯级检测部51、基准点开关51a、以及开关支承部51b与基准梯级100s以及多个梯级100的梯级前车轮220、梯级后车轮230、导轨300等一并被收纳于基准梯级100s下方的机械室107。The reference step detection unit 51 , the reference point switch 51 a , and the switch support unit 51 b are housed under the reference step 100 s together with the reference step 100 s and the step front wheels 220 , the step rear wheels 230 , the guide rails 300 and the like of the plurality of steps 100 . Room 107.

基准梯级100s的基准梯级检测部51是设置在梯级支承部250的下端的板状的部件。基准点开关51a呈框架的一边敞开的形状(U字形)。基准梯级检测部51在基准点开关51a的U字构造的内侧通过,由此检测到基准梯级100s的通过。开关支承部51b的一端被安装在导轨300的下表面,在另一端安装有基准点开关51a。由此,开关支承部51b将基准点开关51a配置在基准梯级检测部51的通过位置。基准点开关51a以及开关支承部51b例如在与基准梯级100s的行进方向正交的方向上配置在与形变传感器40a并排的位置。The reference step detection portion 51 of the reference step 100 s is a plate-shaped member provided at the lower end of the step support portion 250 . The reference point switch 51a has a shape (U-shape) in which one side of the frame is opened. The reference step detection unit 51 detects the passing of the reference step 100s by passing through the inner side of the U-shaped structure of the reference point switch 51a. One end of the switch support portion 51b is attached to the lower surface of the guide rail 300, and the reference point switch 51a is attached to the other end. Thereby, the switch support part 51b arranges the reference point switch 51a at the passing position of the reference step detection part 51 . The reference point switch 51a and the switch support portion 51b are arranged at positions parallel to the strain sensor 40a, for example, in the direction orthogonal to the traveling direction of the reference step 100s.

此处,基准梯级100s的通过由基准点开关51a检测到。然后,假设在脉冲发生器106的计数例如达到100计数值后,基准点开关51a上方的形变传感器40a检测到异常。根据位置检测部50,能够知晓在基准梯级100s的通过后达到100计数值时基准梯级100s前进了多少距离。即、像当形变传感器40a检测到异常时位于形变传感器40a的上方的梯级100例如是从基准梯级100s起的第5个梯级100这样,能够确定检测到异常的梯级100。来自上述脉冲发生器106以及基准点开关51a的信号由自动扶梯诊断装置10的输入部21取得,这样确定出的存在异常的梯级100的位置信息(异常梯级位置信息50i)例如被存储于存储部30。Here, the passage of the reference step 100s is detected by the reference point switch 51a. Then, it is assumed that the deformation sensor 40a above the reference point switch 51a detects an abnormality after the count of the pulse generator 106 reaches, for example, 100 counts. According to the position detection unit 50 , it is possible to know how far the reference step 100 s has advanced when the count value reaches 100 after the reference step 100 s has passed. That is, like the step 100 located above the strain sensor 40a when the strain sensor 40a detects an abnormality, for example, the fifth step 100 from the reference step 100s, the step 100 where the anomaly is detected can be specified. The signals from the pulse generator 106 and the reference point switch 51a are acquired by the input unit 21 of the escalator diagnostic apparatus 10, and the position information (abnormal step position information 50i) of the step 100 having an abnormality identified in this way is stored in the storage unit, for example. 30.

若在预定的梯级100检测到异常,则立刻进行保养检修。该情况下的保养检修是作业人员介入的保养检修。自动扶梯诊断装置10在人介入的下次的保养检修时、即检测到异常后的最近的保养检修时,基于异常梯级位置信息50i,使检测到异常的梯级100移动至预定的检修位置。预定的检修位置例如是指乘降板104a、104b的正下方的位置等。If an abnormality is detected at a predetermined step 100, maintenance and inspection are performed immediately. The maintenance and inspection in this case is a maintenance and inspection in which a worker intervenes. The escalator diagnostic apparatus 10 moves the step 100 in which the abnormality was detected to a predetermined inspection position based on the abnormal step position information 50i at the next maintenance inspection when a human is involved, that is, at the latest maintenance inspection after the abnormality is detected. The predetermined inspection position refers to, for example, a position directly below the getting-off plates 104a and 104b, or the like.

另外,虽然假设基准梯级检测部51设置在基准梯级100s的梯级支承部250,但也可以设置于梯级前车轮220以及梯级后车轮230的任一个车轮。在该情况下,基准梯级检测部51是不会使基准梯级100s产生振动的程度的微小的突起状的部件(未图示)。基准梯级100s作为预定的形变传感器40a的输出信号的变化而被检测。由此,不需要基准点开关51a以及开关支承部51b。即、在上述结构中,基准梯级检测部51、形变传感器40a、以及脉冲发生器106作为位置检测部50发挥功能。In addition, although the reference step detection unit 51 is assumed to be provided on the step support portion 250 of the reference step 100s, it may be provided on any one of the step front wheel 220 and the step rear wheel 230 . In this case, the reference step detection unit 51 is a minute protruding member (not shown) that does not vibrate the reference step 100s. The reference step 100s is detected as a predetermined change in the output signal of the strain sensor 40a. This eliminates the need for the reference point switch 51a and the switch support portion 51b. That is, in the above configuration, the reference step detection unit 51 , the strain sensor 40 a , and the pulse generator 106 function as the position detection unit 50 .

其次,使用图9说明变形例3的自动扶梯诊断装置10的诊断处理。图9是示出实施方式1的变形例3所涉及的自动扶梯诊断处理的顺序的一例的流程图。此处,对步骤S11~步骤S13结束后的处理进行说明。Next, the diagnostic process of the escalator diagnostic apparatus 10 of the modification 3 is demonstrated using FIG. 9. FIG. 9 is a flowchart showing an example of a procedure of an escalator diagnosis process according to Modification 3 of Embodiment 1. FIG. Here, the processing after the completion of steps S11 to S13 will be described.

在步骤S14中,若2个输出信号的偏离为阈值以上(是),则在步骤S31中,与位置检测部50检测到的位置信息对照而确定检测到异常的梯级100的位置。输入部21所取得的位置信息作为异常梯级位置信息50i被存储于存储部30。In step S14 , if the deviation of the two output signals is equal to or greater than the threshold value (Yes), in step S31 , the position of the step 100 where the abnormality is detected is determined by collation with the position information detected by the position detection unit 50 . The positional information acquired by the input unit 21 is stored in the storage unit 30 as abnormal step positional information 50i.

在步骤S32中,在下次的保养检修时,变形例3的自动扶梯诊断装置10读出所存储的位置信息。基于上述位置信息,变形例3的自动扶梯诊断装置10使发生异常的梯级100移动至预定的检修位置。In step S32, in the next maintenance and inspection, the escalator diagnostic apparatus 10 of the modification 3 reads out the stored position information. Based on the above-described position information, the escalator diagnostic apparatus 10 of Modification 3 moves the step 100 in which the abnormality occurred to a predetermined inspection position.

根据变形例3的自动扶梯诊断装置10,能够容易地确定发生异常的部位。并且,由于使异常发生部位自动地移动至预定的检修位置,因此能够实现保养检修时间的削減并抑制异常部位的看漏。According to the escalator diagnostic apparatus 10 of the modified example 3, it is possible to easily specify a location where an abnormality has occurred. In addition, since the abnormality occurrence part is automatically moved to the predetermined inspection position, it is possible to reduce the maintenance and inspection time and suppress the omission of the abnormality part.

[实施方式2][Embodiment 2]

其次,对实施方式2进行说明。实施方式2的自动扶梯诊断装置在诊断梯级链240的伸长这点上与实施方式1的自动扶梯诊断装置10不同。以下,使用图10,仅对与实施方式1的自动扶梯诊断装置10的不同点进行说明。图10是示出实施方式2所涉及的自动扶梯诊断处理的顺序的一例的流程图。Next, Embodiment 2 will be described. The escalator diagnostic apparatus of the second embodiment is different from the escalator diagnostic apparatus 10 of the first embodiment in that it diagnoses the elongation of the step chain 240 . Hereinafter, only differences from the escalator diagnostic apparatus 10 according to the first embodiment will be described using FIG. 10 . 10 is a flowchart showing an example of the procedure of the escalator diagnosis process according to the second embodiment.

实施方式2的自动扶梯诊断装置10也能够应用于上述的实施方式1以及变形例1~3的任一个自动扶梯诊断装置10。以下,说明针对实施方式1的自动扶梯诊断装置10的应用例。The escalator diagnostic apparatus 10 of the second embodiment can also be applied to the escalator diagnostic apparatus 10 of the above-described first embodiment and modifications 1 to 3. Hereinafter, an application example of the escalator diagnostic apparatus 10 according to the first embodiment will be described.

在步骤S41中,自动扶梯诊断装置10的控制部20所具备的输入部21取得在自动扶梯1的设置时检测到的来自形变检测部40的输出信号,并作为设置时检修模式数据31存储于存储部30。在该设置时检修模式数据31中,作为数据也包含输出信号的输出周期。输出信号的输出周期是指预定的梯级100的车轮在预定的形变传感器40a上通过时的输出信号的峰、与随后的梯级100的车轮在该形变传感器40a上通过时的输出信号的峰之间的长度。该输出信号的输出周期是相对于后述的保养检修时的输出信号的输出周期的规定值。In step S41, the input unit 21 included in the control unit 20 of the escalator diagnostic apparatus 10 acquires the output signal from the deformation detection unit 40 detected at the time of installation of the escalator 1, and stores it as the inspection mode data 31 at the time of installation in storage unit 30 . In this setting inspection mode data 31, the output period of the output signal is also included as data. The output period of the output signal refers to the period between the peak of the output signal when the wheel of the predetermined step 100 passes the predetermined deformation sensor 40a and the peak of the output signal when the wheel of the subsequent step 100 passes the deformation sensor 40a. length. The output cycle of the output signal is a predetermined value with respect to the output cycle of the output signal at the time of maintenance to be described later.

这样,输出周期的规定值优选使用设置同一个体的自动扶梯1时的输出信号的数据。这是因为:针对每个自动扶梯1,存在使行进速度的设定不同的情况,在该情况下,输出周期也不同。In this way, it is preferable to use the data of the output signal when the escalator 1 of the same individual is installed as the predetermined value of the output cycle. This is because the setting of the traveling speed may be different for each escalator 1, and in this case, the output cycle is also different.

在步骤S42中,输入部21取得在自动扶梯1的保养检修时检测到的来自形变检测部40的输出信号。在该保养检修时的取得数据中,作为数据也包含输出信号的输出周期。In step S42, the input part 21 acquires the output signal from the deformation|transformation detection part 40 which was detected at the time of the maintenance and inspection of the escalator 1. The acquired data at the time of this maintenance and inspection also includes the output cycle of the output signal as data.

在步骤S43中,控制部20的信号处理部22将自动扶梯1的设置时的输出周期(规定值)与保养检修时的输出周期进行比较。In step S43, the signal processing unit 22 of the control unit 20 compares the output cycle (predetermined value) at the time of installation of the escalator 1 with the output cycle at the time of maintenance.

在步骤S44中,若2个输出信号周期的偏离小于阈值(否),则返回步骤S42,反复进行以下的流程。在步骤S44中,若2个输出信号周期的偏离为阈值以上(是),则信号处理部22判定为保养检修时的输出信号周期异常。In step S44, if the deviation of two output signal cycles is smaller than the threshold value (NO), the process returns to step S42, and the following flow is repeated. In step S44, when the deviation of two output signal cycles is equal to or greater than the threshold value (Yes), the signal processing unit 22 determines that the output signal cycle at the time of maintenance is abnormal.

自动扶梯1通常以恒定速度运行。各个梯级100的车轮在预定的形变传感器40a上通过的间隔也是恒定的。当针对保养检修时的输出信号周期发现阈值以上的偏离时,各个梯级100在形变传感器40a的上方的通过间隔偏移(延迟)。这意味着因劣化等而在梯级链240产生伸长。上述阈值例如根据自动扶梯1的规格值等求出。信号处理部22当保养检修时的输出信号周期异常的情况下判定为在梯级链240产生伸长。The escalator 1 normally runs at a constant speed. The interval at which the wheels of each step 100 pass over the predetermined deformation sensor 40a is also constant. When a deviation of the threshold value or more is found in the output signal cycle at the time of maintenance, the passing interval of each step 100 above the deformation sensor 40a is shifted (delayed). This means that elongation occurs in the step chain 240 due to deterioration or the like. The said threshold value is calculated|required based on the specification value of the escalator 1 etc., for example. The signal processing unit 22 determines that elongation has occurred in the step chain 240 when the cycle of the output signal at the time of maintenance is abnormal.

在步骤45中,控制部20的外部输出部23将自动扶梯1的异常输出至外部。综上,自动扶梯诊断装置10的诊断处理结束。In step 45, the external output part 23 of the control part 20 outputs the abnormality of the escalator 1 to the outside. In conclusion, the diagnostic processing of the escalator diagnostic apparatus 10 is completed.

根据实施方式2的自动扶梯诊断装置10,即便不将乘降板104a、104b卸下而进行确认,也能够检测梯级链240的伸长。由此,能够实现保养检修作业的省力化以及时间削减。并且,能够实现早期的异常检测。According to the escalator diagnostic apparatus 10 of Embodiment 2, even if it confirms without removing the board 104a, 104b, the elongation of the step chain 240 can be detected. Thereby, labor saving and time reduction of maintenance and inspection work can be achieved. Also, early abnormality detection can be realized.

[实施方式3][Embodiment 3]

其次,对实施方式3的自动扶梯诊断装置进行说明。实施方式3的自动扶梯诊断装置在诊断导轨300的变形这点上与实施方式1的自动扶梯诊断装置10不同。以下,援引图4、图5,仅对与实施方式1的自动扶梯诊断装置10的不同点进行说明。Next, the escalator diagnostic apparatus of Embodiment 3 is demonstrated. The escalator diagnostic apparatus of the third embodiment is different from the escalator diagnostic apparatus 10 of the first embodiment in that it diagnoses deformation of the guide rail 300 . Hereinafter, referring to FIGS. 4 and 5 , only the points of difference from the escalator diagnostic apparatus 10 according to the first embodiment will be described.

如所援引的图5所示,在实施方式3的自动扶梯诊断装置10例如应用实施方式1的变形例1所涉及的形变检测部41。并且,作为相对于保养检修时的形变检测部41的输出信号的基准值,优选使用设置同一个体的自动扶梯1时的输出信号的数据。这是因为:在导轨300的设置时,虽然极其稀少,但也存在产生初始形变的情况,存在上述初始形变的量根据各个自动扶梯1而存在偏差的情况。并且还因为:导轨300的变形通常极其微小,要求具有比梯级驱动部200的异常检测更高的精度。As shown in FIG. 5 cited, the strain detection unit 41 according to Modification 1 of Embodiment 1 is applied to the escalator diagnostic apparatus 10 of Embodiment 3, for example. Moreover, it is preferable to use the data of the output signal when the escalator 1 of the same individual is installed as a reference value with respect to the output signal of the deformation|transformation detection part 41 at the time of maintenance and inspection. This is because initial deformation may occur even when the guide rail 300 is installed very rarely, and the amount of the initial deformation may vary among escalators 1 . In addition, since the deformation of the guide rail 300 is usually extremely small, it is required to have higher accuracy than the abnormality detection of the step drive unit 200 .

信号处理部22将自动扶梯1设置时的输出信号和保养检修时的输出信号进行比较,当二者存在预先设定的阈值以上的偏离的情况下,判定为在自动扶梯1的导轨300产生变形。阈值例如根据自动扶梯1的规格值等求出。The signal processing unit 22 compares the output signal at the time of installation of the escalator 1 with the output signal at the time of maintenance and inspection, and determines that the guide rail 300 of the escalator 1 is deformed when there is a deviation greater than or equal to a preset threshold value between the two. . The threshold value is calculated|required based on the specification value of the escalator 1, etc., for example.

援引图4,对在发生地震后的保养检修中使用实施方式3的自动扶梯诊断装置10的情况的处理进行说明。Referring to FIG. 4 , the processing in the case where the escalator diagnostic apparatus 10 according to Embodiment 3 is used for maintenance after an earthquake occurs will be described.

在步骤S11中,自动扶梯诊断装置10的控制部20将来自自动扶梯1的设置时的形变检测部40的输出信号作为设置时检修模式数据31存储于存储部30。In step S11 , the control unit 20 of the escalator diagnostic apparatus 10 stores the output signal from the deformation detection unit 40 at the time of installation of the escalator 1 in the storage unit 30 as the inspection mode data 31 at the time of installation.

若发生地震,则从未图示的地震检测器发出地震发生信号。When an earthquake occurs, an earthquake occurrence signal is sent from an earthquake detector (not shown).

在步骤S12中,接收到地震发生信号的控制部20自动地开始保养检修,输入部21取得来自形变检测部40的输出信号。In step S12 , the control unit 20 that has received the earthquake occurrence signal automatically starts maintenance, and the input unit 21 acquires the output signal from the deformation detection unit 40 .

在步骤S13中,控制部20的信号处理部22将自动扶梯1的设置时的输出信号和保养检修时的输出信号进行比较。In step S13, the signal processing unit 22 of the control unit 20 compares the output signal at the time of installation of the escalator 1 with the output signal at the time of maintenance.

在步骤S14中,若2个输出信号的偏离小于阈值(否),则返回步骤S12,反复进行以下的流程。在步骤S14中,若2个输出信号的偏离为阈值以上(是),则在步骤15中,控制部20的外部输出部23将自动扶梯1的异常输出至外部。In step S14, if the deviation of the two output signals is smaller than the threshold value (NO), the process returns to step S12, and the following flow is repeated. In step S14, when the deviation of the two output signals is equal to or greater than the threshold value (Yes), in step S15, the external output unit 23 of the control unit 20 outputs the abnormality of the escalator 1 to the outside.

综上,自动扶梯诊断装置10的诊断处理结束。检测到导轨300的变形的自动扶梯1被设为停止状态,直至由作业者进行的修复作业结束为止。In conclusion, the diagnostic processing of the escalator diagnostic apparatus 10 is completed. The escalator 1 which detected the deformation|transformation of the guide rail 300 is set to a stop state until the repair work by an operator is complete|finished.

根据实施方式3的自动扶梯诊断装置10,由于在1个轨道220t(或者轨道230t)上设置有多个形变传感器40a,因此,例如能够容易地检测不仅是梯级前车轮220(或者梯级后车轮230)的形变、还能够容易地检测导轨300的因地震等而导致的残留形变。因此,若如上述那样在地震发生后进行借助实施方式2的自动扶梯诊断装置10进行的保养检修,则能够成为在判断可否进行自动扶梯1的再运行时的帮助。According to the escalator diagnostic apparatus 10 of the third embodiment, since the plurality of strain sensors 40a are provided on one rail 220t (or the rail 230t), for example, not only the step front wheel 220 (or the step rear wheel 230) can be easily detected. ) and the residual deformation of the guide rail 300 due to earthquakes and the like can be easily detected. Therefore, performing maintenance and inspection by the escalator diagnostic device 10 of the second embodiment after the occurrence of an earthquake as described above can be helpful in determining whether or not the escalator 1 can be restarted.

[实施方式4][Embodiment 4]

其次,对实施方式4的自动扶梯诊断装置进行说明。实施方式4的自动扶梯诊断装置在判定自动扶梯1的装载状态这点上与实施方式1的自动扶梯诊断装置10不同。以下,使用图11、图12,仅对与实施方式1的自动扶梯诊断装置10的不同点进行说明。图11是示出实施方式4所涉及的梯级100周边的简要结构以及自动扶梯诊断装置10的图。Next, the escalator diagnostic apparatus of Embodiment 4 is demonstrated. The escalator diagnostic apparatus of Embodiment 4 differs from the escalator diagnostic apparatus 10 of Embodiment 1 in that it determines the loading state of the escalator 1 . Hereinafter, only differences from the escalator diagnostic apparatus 10 of the first embodiment will be described with reference to FIGS. 11 and 12 . FIG. 11 is a diagram showing a schematic configuration around the step 100 and the escalator diagnostic apparatus 10 according to the fourth embodiment.

如图11所示,实施方式4的自动扶梯诊断装置10例如优选应用于实施方式1的变形例1的形变检测部41。并且,在自动扶梯诊断装置10的存储部30收纳有设置时装载载荷数据32。设置时装载载荷数据32是在自动扶梯1的设置时以运行模式使自动扶梯1工作、在对自动扶梯1施加有装载载荷的状态下从形变检测部40取得的输出信号的数据。施加有装载载荷的状态例如能够通过搭乘模仿利用者R的人物来形成。此时,例如优选像使自动扶梯1的搭乘者为1名以上、在多个梯级100上等间隔地搭乘有多名以上、以及搭乘最大装载量的人数那样,分为数个等级来取得数据。若装载载荷变大,则导轨300的形变量也变大,来自形变检测部41的输出信号也变大。As shown in FIG. 11 , the escalator diagnostic apparatus 10 of Embodiment 4 is preferably applied to the strain detection unit 41 of Modification 1 of Embodiment 1, for example. In addition, the installation load data 32 is stored in the storage unit 30 of the escalator diagnostic apparatus 10 . The loading load data 32 at the time of installation is data of an output signal obtained from the deformation detection unit 40 when the escalator 1 is operated in the operation mode and a loading load is applied to the escalator 1 when the escalator 1 is installed. The state in which the loading load is applied can be formed by, for example, riding on a character imitating the user R. In this case, for example, it is preferable to obtain data by dividing into several levels such that there are one or more passengers on the escalator 1 , more than one passenger rides on the steps 100 at equal intervals, and the number of people riding the maximum load. When the loading load increases, the amount of deformation of the guide rail 300 also increases, and the output signal from the deformation detection unit 41 also increases.

控制部20的输入部21在自动扶梯1的运行时取得来自形变检测部40的输出信号。信号处理部22将上述输出信号的总和与设置时装载载荷数据32的输出信号的总和进行比较。输出信号的总和是指形变检测部40所包含的所有形变传感器40a的总和。由此,信号处理部22判定此时的自动扶梯1的装载状态。装载状态的判定例如有“低载荷”、“中载荷”、“高载荷”等。此时,当运行时的输出信号的总和为预先设定的阈值以上的情况下,控制部20例如使自动扶梯1的行进速度暂时降低等、进行自动扶梯1的运转调整。此时的阈值例如能够设定成设置时装载载荷数据32的数据中的、最大装载载荷附近时的输出信号的总和。The input part 21 of the control part 20 acquires the output signal from the deformation|transformation detection part 40 at the time of the operation|movement of the escalator 1. The signal processing section 22 compares the sum of the above-mentioned output signals with the sum of the output signals of the load data 32 at the time of installation. The sum of the output signals refers to the sum of all the deformation sensors 40 a included in the deformation detection unit 40 . Thereby, the signal processing part 22 determines the loading state of the escalator 1 at this time. The determination of the loading state includes, for example, "low load", "medium load", "high load", and the like. At this time, when the sum total of the output signals during operation is equal to or greater than a preset threshold value, the control unit 20 adjusts the operation of the escalator 1 by temporarily reducing the traveling speed of the escalator 1 , for example. The threshold value at this time can be set to, for example, the sum of the output signals in the vicinity of the maximum loading load among the data of the loading load data 32 at the time of installation.

其次,使用图12,对实施方式4的自动扶梯诊断装置10的处理进行说明。图12是示出实施方式4的变形例所涉及的自动扶梯诊断处理的顺序的一例的流程图。Next, the process of the escalator diagnostic apparatus 10 of Embodiment 4 is demonstrated using FIG. 12. FIG. 12 is a flowchart showing an example of a procedure of an escalator diagnosis process according to a modification of the fourth embodiment.

在步骤S51中,自动扶梯诊断装置10的控制部20所具备的输入部21取得自动扶梯1的设置时的装载负荷状态下的来自形变检测部40的输出信号,并作为设置时装载载荷数据32存储于存储部30。In step S51 , the input unit 21 included in the control unit 20 of the escalator diagnostic apparatus 10 acquires the output signal from the deformation detection unit 40 in the loading load state at the time of installation of the escalator 1 as the loading load data 32 at the time of installation. stored in the storage unit 30 .

在步骤S52中,输入部21取得在自动扶梯1的运行时来自形变检测部40的输出信号。In step S52, the input part 21 acquires the output signal from the deformation|transformation detection part 40 at the time of the operation|movement of the escalator 1.

在步骤S53中,控制部20的信号处理部22将自动扶梯1的设置时的输出信号的总和与运行时的输出信号的总和进行比较,判定自动扶梯1的装载状态。In step S53 , the signal processing unit 22 of the control unit 20 compares the sum of the output signals at the time of installation of the escalator 1 with the sum of the output signals at the time of operation, and determines the loading state of the escalator 1 .

在步骤S54中,若运行时的输出信号小于阈值(否),则返回步骤S52,反复进行以下的流程。在步骤S54中,若运行时的输出信号为阈值以上(是),则在步骤55中,控制部20进行自动扶梯1的运转调整。In step S54, if the output signal during operation is smaller than the threshold value (NO), the process returns to step S52, and the following flow is repeated. In step S54, if the output signal at the time of operation is equal to or greater than the threshold value (Yes), in step S55, the control unit 20 performs operation adjustment of the escalator 1.

根据实施方式4的自动扶梯诊断装置10,能够抑制在自动扶梯1施加有过载荷的情况。并且,能够避免为了保护自动扶梯1而使自动扶梯1停止的情况。According to the escalator diagnostic device 10 of the fourth embodiment, it is possible to suppress the application of an overload to the escalator 1 . Moreover, the situation where the escalator 1 is stopped in order to protect the escalator 1 can be avoided.
