Description

  The present invention relates to an escalator system, and in particular, a triangular portion where an escalator and a ceiling portion or other upper escalator intersect is formed, and a guard plate composed of a movable warning plate and a fixed protective plate is attached to the triangular portion. The present invention relates to escalator escalator systems.

  The escalator is provided with a moving handrail that moves with the step on the railing, and the passenger usually gets on the appropriate position of the step with the moving handrail. Since the height of the moving handrail is set to a height that passengers can easily hold, the body may get out of the escalator beyond the moving handrail or the luggage may protrude. In addition, the escalator may be formed with a triangular part, which is a part where the escalator and the ceiling or other upper escalator intersect, and when riding on the body from the escalator, there is a risk of falling from the escalator, Since there is a possibility of being caught between the triangular portions, various safety measures are taken for the escalator.

  As the safety measure, for example, it is possible to prevent the escalator from being started by displaying an appropriate boarding position, an announcement of proper boarding, or the like. In addition, a guard plate composed of a plastic movable warning plate and a fixed protective plate is installed in the triangular portion to prevent the triangular portion from being caught due to the action of getting out from the escalator. These measures prevent escalators from being launched and prevent accidents that may occur when they are launched, but further enhance the safety alert function for passengers and further improve safety. It is desired to plan.

  In view of such a situation, a safety device or the like has been proposed for enhancing the alerting function for passengers and improving the safety of the escalator. For example, in Patent Document 1, a triangular portion provided with an inclined front edge portion formed so that the vertical front edge and the fixed object do not intersect at a right angle is formed in a triangular portion that is an intersecting portion of the vertical front edge and the fixed object. A fixed protective plate is disclosed. Furthermore, in Patent Document 1, this fixed protective plate can substantially eliminate the right-angled portion and realize a cross shape that does not sandwich the head or neck, and naturally, greatly increases the safety of passengers in the narrow space. It can be improved.

  Patent Document 2 discloses a protection plate attached to a building ceiling, a beam, or other escalator so as to be rotatable about an axis perpendicular to the plate surface at a position above a center of gravity on a vertical line passing through a substantially center of gravity position. A detector that detects the rotation about the axis of the protective plate, a notification means that issues an alarm based on an output signal from the detector, and the escalator is stopped or operated based on the output signal from the detector. An escalator safety device is disclosed that includes control means for controlling the vehicle to decelerate.

  As described above, according to the fixed protection plate of Patent Document 1, there is a possibility that the impact when the passenger comes into contact with the fixed protection plate may be reduced. Even when a strong force is applied to the plate, the operation of the escalator is not restricted, so there is still room for improvement from the viewpoint of improving safety.

  On the other hand, according to the safety device of Patent Document 2, the contact of the passenger with the protective plate is detected by the detector and the operation of the escalator is restricted, but this safety device has a complicated and greatly oscillating structure. Therefore, there are problems in terms of cost and durability. Further, since the protective plate swings greatly, there is a possibility that the child's mischievous heart is stimulated, and the escalator operation is frequently stopped due to mischief.

  An object of the present invention is to provide an escalator system capable of improving safety by restricting operation of an escalator when a passenger or the like comes into contact with a simple and highly durable fixed protective plate. In addition, another object of the present invention is to effectively prevent the operation of the escalator from being restricted by a situation where the operation of the escalator should not be restricted, such as a contact with the fixed protection plate by mischief, etc. To achieve both safety and safety.

  The escalator system according to the present invention includes an escalator based on a fixed protection plate attached to a fixed object in a triangular portion of the escalator, a detection unit that detects that force is applied to the fixed protection plate, and detection information by the detection unit. And a control unit that regulates the operation of the vehicle.

  According to the said structure, when a passenger contacts a fixed protection board and force is added, it is possible to perform the driving | running | working regulation (for example, stop of the escalator driving | operation) of an escalator, and aim at the improvement of safety | security. it can. The fixed protection plate has a fixed structure that does not swing greatly, so that it has excellent durability, and when a passenger or the like comes into contact, the forcing action is forced by the resistance received from the fixed protection plate. It also has the effect of prohibiting it.

  Moreover, it is preferable that a detection part is an attachment part of a fixed object and a fixed protection board, Comprising: It installs between a fixed object and a fixed protection board.

  According to the said structure, it can be set as a simple and cheap fixed protection board, changing almost the form of the existing fixed protection board. In addition, since a detection part will be installed in the position where it is hard to see from a passenger, mischief etc. with respect to a detection part can also be prevented.

  In addition, it is preferable that a predetermined space is formed between the fixed object of the attachment portion and the fixed protection plate, and an elastic member is provided that elastically deforms and reduces the predetermined space when a force is applied to the fixed protection plate.

  According to the above configuration, it is easy to attach the fixed protection plate to the fixed object, and the force acts on the detection unit only when a force is applied to the fixed protection plate, so that improvement in detection accuracy can be expected.

  Moreover, it is preferable that a control part regulates the driving | running of an escalator, when the force detected by the detection part exceeds the preset threshold value.

  According to the above configuration, it becomes easier to specify whether or not the force is applied by contact that should regulate the operation of the escalator, and the compatibility of passenger convenience and safety can be achieved at a higher level. It becomes possible to plan. In other words, it is assumed that the force applied by tampering with the fixed protective plate or the inadvertent contact with the hand is smaller than the contact force that should regulate the operation of the escalator. By setting the threshold value, it is possible to improve the accuracy of determining whether or not the force is applied by the contact that should regulate the operation of the escalator.

  In addition, the detection unit is an attachment unit between the fixed object and the fixed protection plate and is installed in at least two places between the fixation object and the fixed protection plate, and the control unit detects information detected by at least two detection units. Based on the above, it is preferable to regulate the operation of the escalator.

  According to the above configuration, it is possible to achieve both passenger convenience and safety by preventing escalator operation restrictions due to mischief and the like. For example, when a hand hits due to contact or carelessness due to mischief, it is assumed that a force is often applied to the outside of the escalator, that is, in a direction intersecting the traveling direction, while the escalator is operated. For example, in the case where the head or neck collides with the fixed protection plate due to the start-up, for example, when the head is pushed out, a force is applied exclusively along the traveling direction of the escalator. Therefore, it is assumed that the force detected by a plurality of detection units having different installation positions between the fixing target of the attachment unit and the fixed protection plate is different between contact due to mischief and the like and contact that should regulate the operation of the escalator. As a result, it is possible to execute the operation regulation by specifying to some extent whether or not the force is applied by the contact that should regulate the operation of the escalator.

  Moreover, it is preferable that a control part regulates the driving | running of an escalator when the difference of the force detected by the at least 2 detection part exceeds the preset threshold value.

  According to the above configuration, since the threshold value is set for the force detected by the plurality of detection units having different installation positions in the mounting unit, is the force applied by the contact that should regulate the operation of the escalator? The accuracy of determining whether or not can be further improved.

  Further, the control unit regulates the operation of the escalator when a state where the force detected by the detection unit or the difference between the forces detected by the at least two detection units exceeds a preset threshold value continues for a predetermined time or more. It is preferable to do.

  The above configuration is particularly preferable from the viewpoint of improving determination accuracy as to whether or not the force is applied by contact that should regulate the operation of the escalator. In other words, when a hand is touched by mischief or carelessness, it is assumed that the time during which the force is applied to the fixed protective plate is shorter than when the head and neck collide with the fixed protective plate due to launch. Therefore, it is extremely useful to determine whether or not the state where the detected value exceeds the threshold value continues for a predetermined time or more.

  Moreover, it is preferable that a detection part is each installed in the both ends along the advancing direction of the escalator of an attachment part.

  According to the above configuration, when a force along the traveling direction of the escalator is applied to the fixed protection plate, the difference between the forces detected by the two detection units becomes larger. Can be set to a large value, which is preferable from the viewpoint of improving the accuracy of determination as to whether or not it is a force applied by contact that should regulate the operation of the escalator.

  Also, with respect to the fixed object at the triangular part of the escalator, a movable warning plate attached to the lower floor side than the fixed protection plate, a contact detection unit that detects that force is applied to the movable warning plate, and attention to passengers It is preferable that the control unit causes a warning by the warning unit to be executed based on detection information by the contact detection unit.

  According to the said structure, it can be anticipated that an approach etc. will be stopped by a warning and the contact to a fixed protection board will be suppressed.

  According to the escalator system according to the present invention, it is possible to improve safety by regulating the operation of the escalator when a passenger or the like comes into contact with the fixed protection plate. In addition, it is possible to effectively prevent the operation of the escalator from being restricted by situations where the operation of the escalator should not be restricted, such as contact with a fixed protective plate, and it is possible to achieve both passenger convenience and safety. become.

  Embodiments according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of an escalator system 10 according to an embodiment of the present invention, and FIG. 2 is a schematic diagram showing a cross section taken along line AA of FIG. FIG. 3 is a view showing the fixed protective plate 13 removed from the ceiling portion 15.

  As shown in FIG. 1, the escalator system 10 is a system for the purpose of improving safety in the triangular portion 12 of the escalator 11, and includes a fixed protection plate 13 and a movable warning plate 14 in the triangular portion 12. A guard plate is provided. As described above, the triangular portion 12 is a portion where the escalator 11 and the ceiling portion 15 or other upper escalator intersect, and will be described below as a portion where the escalator 11 and the ceiling portion 15 intersect. The escalator 11 is an ascending escalator, and the step 16 and the moving handrail 17 shown in FIG. 1 will be described as moving upward.

  The escalator system 10 includes a fixed protection plate 13 installed on the ceiling portion 15 of the triangular portion 12, a detection unit 18 that detects that a passenger or the like has contacted the fixed protection plate 13 and applied a force, and a detection unit 18. A control unit 19 that regulates the operation of the escalator 11 based on the detection information is provided as a main component.

  The fixed protection plate 13 is installed to prevent a passenger or the like from being caught between the triangular portions 12. The fixed protection plate 13 has a fixed configuration that is fixed to the ceiling portion 15 to be fixed without swinging greatly like the movable warning plate 14. Accordingly, even when a passenger who has traveled from the escalator 11 comes into contact with the fixed protective plate 13, the fixed protective plate 13 does not swing greatly, and the passenger is forcibly prohibited from entering due to the resistance received from the fixed protective plate 13. The In the escalator system 10, the safety can be further improved by the functions of the detection unit 18 and the control unit 19 in addition to the resistance force of the fixed protective plate 13.

  The fixed protection plate 13 is installed on the ceiling portion 15 in the triangular portion 12, and includes a flat plate portion 20, a front edge guard portion 21, and an attachment portion 22. The flat plate portion 20 is a flat plastic plate so that the mounting portion 21 extends along the traveling direction of the escalator 11 and the end surface of the ceiling portion 15 and the flat surface of the flat plate portion 20 are substantially flush with each other. Installed. The flat plate portion 20 has a trapezoidal shape whose area decreases toward the upper floor side direction, and the lower floor side front edge portion of the flat plate portion 20 has a cylindrical shape for suppressing impact at the time of collision. The front edge guard part 21 is installed. As shown in FIGS. 2 and 3, an L-shaped attachment portion 22 is attached to the upper end portion of the flat plate portion 20, and the fixed protective plate 13 is installed on the ceiling portion 15 by the attachment portion 22 as described above. Has been. As the attachment portion 22, a metal fitting such as a stainless steel plate can be used, and the ceiling side attachment portion 23 is installed at a position where the attachment portion 22 is also attached to the ceiling portion 15, and fastened with a fastening member 24 such as a screw. Is done.

  The detection unit 18 has a function of detecting that a passenger or the like has come into contact with the fixed protection plate 13 to apply force. Various detectors can be used as the detector 18 as long as the detector 18 can detect that a force is applied to the fixed protective plate 13. For example, a mechanical switch (micro switch, limit switch) that is turned on when a predetermined force is applied, a sensor (load cell) that can measure the applied force quantitatively, or a metal mounting portion 22 and a ceiling side mounting Examples include a proximity sensor, a displacement sensor, and a capacitance sensor that can measure the distance of the unit 23. Among these, it is preferable to apply a sensor capable of quantitatively measuring the applied force from the viewpoint of easily specifying the force applied by the contact that should regulate the operation of the escalator 11. Sensors that can measure force include sensors using various piezoelectric elements (piezo film, etc.) and so-called load cells. Electromagnetic, electrostatic capacitance, gyro, strain gauge, piezoelectric, etc. There are load cells of various detection methods. In general, a so-called strain gauge type in which a so-called strain gauge whose resistance value changes in accordance with the amount of deformation is installed on the surface of the load cell is widely used. be able to. As will be described later, in order to install on the upper surface of the attachment portion 22, a thin plate type sensor is preferable.

  The detection unit 18 is a force applied to the fixed protection plate 13, and can measure a force due to a contact that should regulate the operation of the escalator 11, such as a head or neck colliding with the fixed protection plate 13 due to a passenger's departure action. It is necessary to install it at a possible position. Examples of the installation position include an attachment portion (attachment portion 22, ceiling-side attachment portion 23) between the front edge guard portion 21 and the fixed protection plate 13 and the ceiling portion 15, Examples include between members. The detection unit 18 is concealed to prevent mischief with respect to the detection unit 18 and, as will be described later, a plurality of detection units 18 are installed to specify that force is applied by contact that should regulate the operation of the escalator 11. 2 and FIG. 3, the detection unit 18 is preferably installed on the upper surface of the attachment unit 22. In addition, the same effect can be acquired also when installing in the lower surface of the ceiling side attaching part 23. FIG. Hereinafter, the detection unit 18 will be described as a sensor such as a load cell that can quantitatively measure the force applied to the detection unit 18 and installed on the upper surface of the attachment unit 22.

  A fastening member insertion hole 25 for inserting the fastening member 24 is formed in the attachment portion 22 and the ceiling side attachment portion 23, and both members are fastened to each other by the fastening member 24. As described above, since the detection unit 18 is installed on the upper surface of the attachment unit 22, the elastic member 26 is preferably installed on the upper surface of the installation unit 22 as shown in FIGS. 2 and 3. The elastic member 26 is required to be a member that forms a space between the attachment portion 22 and the ceiling side attachment portion 23 and can be elastically deformed to reduce the space when a force is applied to the fixed protection plate 13. The The detection unit 18 does not come into contact with the ceiling-side mounting portion 23 when no force is applied to the fixed protection plate 13 by the elastic member 26, and when the elastic member 26 is elastically deformed due to the force applied to the fixed protection plate 13, The force applied to the fixed protective plate 13 in contact with the side attachment portion 23 can be detected. Therefore, since the force acts on the detection unit 18 only when a force is applied to the fixed protective plate 13, an improvement in detection accuracy can be expected. In addition, it is also possible to detect the force applied to the fixed protective plate 13 due to deformation (strain) of the elastic member 26 by installing the detection unit 18 constituted by a strain gauge or the like on the elastic member 26.

  The elastic member 26 is not particularly limited as long as it is a member that can be elastically deformed by a force applied by contact with the fixed protective plate 13, and rubber, a spring, or the like can be applied. For example, the elastic member 26 can be a ring-shaped rubber member that surrounds the periphery of the fastening member 24 as shown in FIGS. In addition, as shown in FIG. 3, if the screw groove is not formed in the fastening member insertion hole 25 and the diameter thereof is set slightly larger than the diameter of the fastening member 24, the fixed protection plate 13 receives a force. This is preferable because the elastic member 26 is easily deformed and the operability of the detection unit 18 is improved. The attachment portion 22 and the ceiling side attachment portion 23 are fastened so that a space is formed between the detection portion 18 and the ceiling side attachment portion 23 by the elastic member 26 when no force is applied to the fixed protection plate 13. It is necessary to conclude by adjusting.

  The detection unit 18 is preferably installed at at least two places on the upper surface of the attachment unit 22, and as shown in FIG. 3, the two detection units 18 a and 18 b are in the vicinity of both end portions along the longitudinal direction of the attachment unit 22. Each can be installed. Here, the mischief with respect to the fixed protective plate 13 is not an act of applying a force in the direction indicated by the black arrow that is the traveling direction of the escalator 11, but a force is applied in the direction indicated by the white arrow, such as hitting or striking the flat plate portion 20. It is assumed that there are many. In particular, when the movable warning plate 14 is installed adjacent to the fixed protection plate 13, it is predicted that the tendency becomes more remarkable. On the other hand, the force applied by the contact that restricts the operation of the escalator 11 such as the head and neck colliding with the fixed protective plate 13 due to the passenger's entry action is exclusively applied to the leading edge guard portion 21 in the direction indicated by the black arrow. . Accordingly, in the latter case, the force detected by the detection unit 18b installed at the rear in the traveling direction is larger than the force detected by the detection unit 18a installed at the front in the traveling direction. That is, the elastic member 26b is greatly deformed by receiving a larger force than the elastic member 26a. On the other hand, in the former case, the difference between the forces detected by the detectors 18a and 18b is small, and the deformation amounts of the elastic members 26a and 26b are approximately the same. If the detection information by the two detectors 18a and 18b installed in this way is taken into consideration, it is possible to specify the contact that should restrict the operation of the escalator 11 to some extent and execute the operation restriction. In addition, in the attachment part 22, if the two detection parts 18a and 18b are installed at both ends along the traveling direction of the escalator 11, that is, both ends along the longitudinal direction of the attachment part 22, respectively, When a force along the advancing direction of the escalator 11 is applied, the difference between the forces detected by the two detection units 18a and 18b becomes larger, so that it becomes easier to set a threshold value for a difference between detection values described later.

  In addition, as an installation pattern of the detection unit 18 on the upper surface of the attachment unit 22, for example, as shown in FIG. 4A, in the installation pattern shown in FIG. 3, the detection unit 18a is moved to the center along the longitudinal direction. It is also possible to use a pattern. Moreover, as shown in FIG.4 (b), it can also be set as the installation pattern along the width direction of the attaching part 22. As shown in FIG. In this installation pattern, when a force along the traveling direction of the escalator 11 is applied, the difference in force between the detection units 18a and 18b is small, and when a force toward the outside of the escalator 11 is applied, the detection unit 18b detects the force. Force> force detected by the detector 18a. Furthermore, as shown in FIG.4 (c), it can also be set as the installation pattern along the diagonal of the attaching part 22. As shown in FIG. In this installation pattern, when a force along the traveling direction of the escalator 11 is applied, the force detected by the detection unit 18b> the force detected by the detection unit 18a, and when a force toward the outside of the escalator 11 is applied. The force detected by the detection unit 18a> the force detected by the detection unit 18b. That is, in any of the installation patterns shown in FIG. 4, it is possible to easily specify the force due to the contact that should regulate the operation of the escalator 11. In addition, as shown to the figure, the formation position of the fastening member insertion hole 25 which is a fastening location can also be changed, for example, it can also form in the center part so that the detection part 18 may operate | move easily. The installation position of the elastic member 26 can also be installed at various positions independently of the fastening location.

  As shown in FIG. 1, a movable warning plate 14 can be attached to the lower floor side of the fixed protection plate 13 in the triangular portion 12. The movable warning plate 14 is installed in order to prevent passengers from being caught in the triangular portion 12, similarly to the fixed protection plate 13, but is not a fixed structure like the fixed protection plate 13, The escalator 11 is suspended from the ceiling 15 with a chain or the like so as to swing with respect to the traveling direction and the outer direction. As shown in the figure, the movable warning plate 14 is a plastic flat plate similar to the fixed protective plate 13, the flat plate is along the traveling direction of the escalator 11, and the end surface of the ceiling portion 15 is substantially the same as the flat plate surface. It is attached to be a flat surface.

  The movable warning plate 14 may be provided with a contact detection unit 27 that detects that a passenger or the like has contacted the movable warning plate 14. Then, when the contact is detected by the contact detection unit 27, the control unit 19 can execute a warning by issuing a buzzer sound or lighting a warning lamp. Thus, if a warning is issued by touching the movable warning plate 14 to alert the passenger, it can be expected to suppress contact with the fixed protective plate 13. As the contact detection unit 27, a known detector that can detect vibration due to contact with the movable warning plate 14, displacement due to swinging, and the like can be applied. For example, a vibration sensor, an acceleration sensor, a displacement sensor, a touch A sensor (capacitance sensor) can be used.

  Further, the escalator system 10 may include a lower area warning plate (not shown) for preventing the movable warning board 14 from getting out of the escalator 11 in the lower floor area and protruding of the luggage. For example, the lower area warning plate is preferably made of an elastic body such as rubber in consideration of safety when a passenger or the like comes in contact, and has a form protruding above the upper surface of the moving handrail 17 can do. The lower area warning plate can be installed on the balustrade part or the deck part outside the moving handrail 17 and can easily come into contact with the lower area warning plate when getting out of the escalator 11 without disturbing the use of the moving handrail 17. Since it can be understood, the effect of deterring launching works. In addition, an infrared sensor that irradiates infrared rays along the escalator 11 or a contact detection sensor on the lower area warning plate may be installed, and a means for detecting a launching action may be provided.

  As described above, the escalator system 10 includes the control unit 19 that regulates the operation of the escalator 11 based on the information detected by the detection unit 18, and the control unit 19 includes a determination unit 28, an operation regulation unit 29, and a warning. Means 30. The control unit 19 includes a CPU, an input device used to input control parameters used when executing the functions of each means described later, a recording device that stores the input control parameters, control programs, and the like, An apparatus including an output port and the like, which can be configured by a computer. The functions of the above means can be realized by executing software, and specifically, can be realized by executing a control program stored in a storage device. In addition, the control part 19 can be comprised as a part of control apparatus which controls the driving | operation of the escalator 11 installed in the upper machine room etc. which are not shown in figure. The detection unit 18 and the contact detection unit 27 are connected to the control unit 19, and a detection signal is input to the control unit 19.

  The determination means 28 has a function of determining whether or not the operation restriction means 29 is to restrict the operation of the escalator 11 based on the detection information by the detection unit 18. The determination contents executed by the determination means 28 include, for example, 1) whether or not the force detected by one detection unit 18 exceeds a preset threshold value, and 2) the force detected by two detection units 18. 3) whether the detected force or the state in which the detected force difference exceeds the threshold value continues for a predetermined time or more. Among these determination contents, 2) and 3) are preferable, and it is more preferable to incorporate both 2) and 3) as determination contents. By performing such a determination, it becomes easy to selectively specify only the contact that should regulate the operation of the escalator 11.

  It is preferable that the threshold value serving as a determination criterion of the determination unit 28 is a value that eliminates a force applied by mischief or a careless contact with the flat plate portion 20. In addition, when the hand is touched by mischief or carelessness, it is assumed that the time during which the force is applied to the fixed protective plate 13 is relatively short, so the predetermined time is set to about 1 to 2 seconds, for example. If it is set to, a force applied due to mischief or careless contact with the hand can be eliminated, and safety can be ensured. In addition, when the force applied to the fixed protective plate 13 is detected by the detection unit 18, it is also possible to set the threshold only for the time when the force is detected without setting the threshold based on the detected force.

  The determination unit 28 can also set a plurality of threshold values. For example, when it is determined whether or not the detected force or the state where the difference between the forces exceeds the threshold value continues for a predetermined time or more, a large value is set as the first threshold value, and the second threshold value is more A small value or only a predetermined time is set. Then, when the force applied to the fixed protective plate 13 is detected by the detection unit 18, it is determined whether or not the state exceeding the first threshold value has continued for a predetermined time or more. It can be changed to the threshold value of 2, and it can be further determined whether or not it has continued for a predetermined time or more. If the detected force exceeds the threshold value, a warning such as a buzzer sound is issued prior to the operation regulation. If the detected force still exceeds the threshold value continues for a predetermined time or longer, the escalator 11 is operated. It can also be determined that the situation should be regulated.

  When it is determined by the determination means 28 that the operation of the escalator 11 should be restricted, for example, it is determined that the difference between the forces detected by the two detection units 18 exceeds a preset threshold value. Has a function of regulating the operation of the escalator 11. Here, examples of the restriction of driving include deceleration of driving speed, stop of driving, and the like, but it is preferable to stop driving from the viewpoint of improving safety. Specifically, the operation restricting means 29 gives an operation stop control command to the escalator drive unit 31 that drives the step 16 and the moving handrail 17, and the escalator drive unit 31 stops the operation based on the control command. . In addition, when stopping the operation of the escalator 11 (when stopping the operation of the escalator drive unit 31), it is preferable to alert the passenger by issuing a warning sound.

  The warning means 30 has a function of issuing a warning such as issuing a buzzer sound from the speaker 32 when a detection signal is acquired from the contact detection unit 27. As a warning, not only a warning by sound but also a visual warning by flashing light or the like can be used. It is assumed that the contact with the movable warning plate 14 occurs more frequently than the contact with the fixed protection plate 13 due to mischief or the like, so that it is not preferable to perform the operation regulation by the contact, and the fixed protection plate 13 is not preferable. It is preferable to implement a warning to suppress contact with

  The effect | action of the escalator system 10 of the said structure is demonstrated in detail using FIG. Specifically, the escalator system 10 is configured as shown in FIGS. 1 to 3, and a movable warning plate 14 is attached to the triangular portion 12 in addition to the fixed protection plate 13. A description will be given assuming that a warning function is provided.

  First, it is determined whether or not a passenger or the like has contacted the movable warning plate 14 and has been detected by the contact detection unit 27 (S10). As described above, a vibration sensor or the like can be installed as the contact detection unit 27, and when the movable warning plate 14 vibrates due to a passenger's contact or the like, detection by the contact detection unit 27 is performed and a detection signal is transmitted to the control unit 19. Is done.

  In S10, when it is determined that the detection by the contact detection unit 27 has been made, a buzzer sound is issued from the speaker 32 and a warning is executed (S11). This procedure is executed by the function of the warning means 30.

  Even when the start-up action is not stopped by the warning of S11 and a force is applied by touching the fixed protection plate 13, it is determined whether or not the difference ΔP in the force detected by the detectors 18a and 18b exceeds a threshold value. (S12). ΔP is a value obtained by subtracting the detection value of the detection unit 18a from the detection value of the detection unit 18b. When ΔP exceeds the threshold value, the detection value of the detection unit 18b> the detection value of the detection unit 18a, and the force is applied in the direction indicated by the black arrow in FIG. There is a high possibility that the force is applied by power contact, and it is further determined whether or not to restrict the operation of the escalator 11 in the next step. On the other hand, when ΔP is lower than the threshold value, it is determined that the detection value of the detection unit 18b ≦ the detection value of the detection unit 18a, that is, contact due to mischief or the like and it is not necessary to regulate the operation of the escalator 11.

  When it is determined in S12 that ΔP has exceeded the threshold, it is further determined whether or not a state in which ΔP has exceeded the threshold has elapsed for a predetermined time or longer (S13). In the case of contact due to mischief or the case where the hand is touched instantaneously, it is assumed that the time during which ΔP exceeds the threshold continues for a relatively short time. Therefore, when the state where ΔP exceeds the threshold is less than the predetermined time, it is determined that the contact is caused by mischief or the like and it is not necessary to regulate the operation of the escalator 11. On the other hand, when the state in which ΔP exceeds the threshold value has passed for a predetermined time or more, there is a high possibility that it is a force applied by contact that should regulate the operation of the escalator 11, and therefore the process proceeds to the next step. The procedures of S11 and S12 are executed by the determination unit 28.

  In S13, when it is determined that the state in which ΔP exceeds the threshold value has passed for a predetermined time or longer, the operation of the escalator 11 is to be restricted, and the operation of the escalator 11 is stopped (S14). This procedure is executed by the operation restricting means 29. The operation restricting means 29 gives an operation stop control command to the escalator drive unit 31, and the escalator drive unit 31 stops the operation based on the control command.

  As described above, according to the escalator system 10, the fixed protective plate 13 and the detection unit 18 that is installed at two positions on the upper surface of the attachment unit 22 and detects that force is applied to the fixed protective plate 13, And a control unit 19 that regulates the operation of the escalator 11 based on information detected by the detection unit 18. Therefore, when the passenger contacts the fixed protective plate 13 and a force is applied, the operation regulation of the escalator 11 is executed. It is possible to improve safety. In addition, it is possible to prevent passengers from operating the escalator 11 due to mischief and to achieve both passenger convenience and safety.
