The top view of the vicinity of the upper floor side entrance / exit in FIG. 1 and the lower floor side entrance / exit. The flowchart which shows the evacuation guidance control implemented by the escalator in embodiment.

  Below, the passenger conveyor concerning an embodiment is explained in detail based on a drawing. In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will not be repeated.

  In the present embodiment, an escalator will be described as an example of a passenger conveyor that operates by rotating a plurality of steps connected endlessly. First, with reference to FIGS. 1-3, the structure of the escalator 1 which concerns on this embodiment is demonstrated. FIG. 1 is a longitudinal sectional view showing a schematic configuration of an escalator (passenger conveyor) according to the embodiment, and FIG. 2 is a schematic view in which the periphery of a human sensor, a voice guidance device, and an evacuation light in FIG. 1 is enlarged. FIG. 3 is a plan view of the vicinity of the upper floor entrance / exit and the lower floor entrance / exit in FIG.

  As shown in FIG. 1, the escalator 1 includes a plurality of steps 5 connected endlessly between the drive wheel 3 and the driven wheel 4 inside a truss (structure frame) 2, and decelerates to the drive wheel 3. The plurality of steps 5 are configured to move between the drive wheels 3 and the driven wheels 4 by power supplied from the motor 21 via the machine 6 and the drive chain 7.

  When the escalator 1 operates in the descending direction, the plurality of steps 5 are advanced from the truss 2 with the adjacent steps 5 facing each other in the traveling direction at the upper entrance (upper floor side entrance 8), In the upper transition curve, the step between adjacent steps 5 is enlarged and transitioned to a staircase shape, lowered in a stepped manner in the middle slope portion, and in the lower transition curve, the step between adjacent steps 5 is reduced to a horizontal shape. And enters the truss 2 again in a horizontal state at the lower exit (lower floor side entrance 9). Then, after entering the truss 2, it is inverted upward, the return side is elevated in a horizontal state, is inverted again, and is advanced from the truss 2 at the upper floor side entrance 8. In the escalator 1 that operates in the upward direction, the above operation is reversed. The upper floor entrance 8 and the lower floor exit 9 are provided with boarding plates 10 through which the user passes when the escalator 1 gets on and off, and the step 5 is a tread on the upper surface on which the user is placed. Is moved from the truss 2 along the boarding / alighting plate 10, or enters the truss 2.

  Further, the escalator 1 includes a pair of balustrades 11 on both sides in the traveling direction of the step 5. Each of the balustrades 11 is a skirt guard 12 provided immediately next to the step 5 and extending over the upper floor side entrance / exit 8 and the lower floor side entrance / exit 9; The side board 13 provided over the side entrance 8 and the lower floor side entrance 9 and the annular handrail belt 14 attached along the outer periphery of the side board 13 are provided. That is, the skirt guard 12 is provided on both sides of the step 5. The escalator 1 is configured such that the handrail belt 14 of the balustrade 11 circulates in the same direction as the step 5 in accordance with the movement of the step 5 described above.

  When the handrail belt 14 moves in the same direction as the traveling direction of the step 5 (the traveling direction of the escalator 1), it moves along the upper outer periphery of the side plate 13, and then reverses the traveling direction so that the traveling direction of the escalator 1 When moving in the opposite direction, it enters the skirt guard 12 and moves along the lower outer periphery of the side plate 13. The balustrade 11 is provided with a safety device 15 at the entrance of the handrail belt 14 at the upper floor side end and the lower floor side end of the skirt guard 12. The safety device 15 detects that a foreign object enters the skirt guard 12 by being caught in the handrail belt 14. The escalator 1 can stop the operation according to the detection of the safety device 15, for example.

  Such an operation of the escalator 1 is realized by controlling an inverter device (not shown) and the motor 21 by a control device 16 (control means) installed in the truss 2.

  Furthermore, in this embodiment, when a large shaking earthquake occurs, the control device 16 notifies the user of the escalator 1 of the occurrence of the earthquake, stops the operation of the escalator 1, and further, It is configured to execute a control (hereinafter referred to as “evacuation guidance control”) for presenting the direction of the evacuation floor (upper floor side or lower floor side) to a person around the escalator 1 and guiding the evacuation. Yes. In order to realize such evacuation guidance control, the control device 16 includes a human sensor 17, a voice guidance device 18 (voice guidance means), evacuation lights 19a and 19b (display means), and an earthquake detector 20 (disaster detection means). ), And electrically connected to the motor 21.

  As shown in FIG. 1, the human sensor 17, the voice guidance device 18, and the evacuation light 19 a are provided on the surface of the upper floor side entrance 8 and the lower floor side entrance 9 on the step 5 side of the skirt guard 12 of the balustrade 11. Is provided. The human sensor 17, the voice guidance device 18, and the evacuation light 19 a may be provided on both of the pair of skirt guards 12 provided on both sides with respect to the traveling direction of the step 5, or provided on one side. Also good.

  The human sensor 17 can detect the passage of a user riding on the step 5 or an object placed on the step 5 (hereinafter collectively referred to as “user etc.”). When the human sensor 17 detects the passage of a user or the like, the human sensor 17 transmits information to that effect to the control device 16. When the escalator 1 moves in the downward direction, the control device 16 indicates that the user has entered the escalator 1 because the human sensor 17 at the upper floor side entrance / exit 8 senses the passage of the user, etc. It is possible to detect that the user has descended from the escalator 1 when the human sensor 17 at the lower floor entrance 9 senses the passage of the user or the like. When the escalator 1 moves in the upward direction, the detection content of the control device 16 based on the detection of the human sensor 17 at the upper floor entrance 8 and the lower floor entrance 9 is the reverse of the above.

  The voice guidance device 18 presents various types of voice information to the user of the escalator 1 in response to a command from the control device 16. In this embodiment, when a large shaking earthquake occurs, the voice guidance device 18 informs the user that a large shaking earthquake has occurred, or stops the operation of the escalator 1 due to the occurrence of an earthquake. Play a voice message to evoke. In addition, after the escalator 1 stops operating in response to the occurrence of an earthquake, the direction of the evacuation floor (upper floor side or lower floor side) is presented and a voice message for guiding the user to the evacuation floor is played. Note that the voice information presented by the voice guidance device 18 is a voice that can alert the user to the occurrence of an earthquake or prompt an evacuation guide even if the user of the escalator 1 panics when an earthquake occurs. Is preferable. For example, there are methods such as raising the volume, adding sound effects, and playing sound only in the direction of the evacuation floor (upper floor side or lower floor side) as compared with normal driving.

  The evacuation light 19a displays information such as symbols and characters for guiding the direction of the evacuation floor (upper floor side or lower floor side) in response to a command from the control device 16, and evacuates the user. It is configured to present directions and guide you to the evacuation floor. As shown in FIG. 2, for example, the evacuation lamp 19a is configured by arranging a plurality of light emitters such as illumination and LEDs in a planar (two-dimensional) arrangement. Information such as an arrow symbol that guides the direction of the evacuation floor can be displayed by causing some of the plurality of light emitters to emit light.

  As shown in FIGS. 1 and 3, the evacuation lamp 19 b is provided on the upper surface of the boarding board 10 at the upper floor side entrance 8 and the lower floor side entrance 9. Similarly to the evacuation light 19a, the evacuation light 19b displays information such as symbols and characters for guiding the direction of the evacuation floor in response to a command from the control device 16, and indicates the evacuation direction to the user. Presented and configured to guide you to the evacuation floor. Similarly to the evacuation lamp 19a, the evacuation lamp 19b is configured by arranging a plurality of light emitters such as illumination and LEDs in a planar (two-dimensional) arrangement. By causing some of these light emitters to emit light, for example, as shown in FIG. 3, information such as an arrow symbol for guiding the direction of the evacuation floor can be displayed.

  Note that the information on the evacuation direction presented by the evacuation lights 19a and 19b is the information that the evacuation lights 19a and 19b are operating even when the escalator 1 user panics when an earthquake occurs. It is preferable to notice that is presented. For example, there are methods such as increasing the amount of light, changing the color, and creating a lighting pattern so that the light emitters are sequentially turned on according to the evacuation direction as compared with the normal operation.

  The earthquake detector 20 can detect that a large shaking earthquake has occurred. For example, when the seismic intensity of the earthquake that has occurred is equal to or greater than a predetermined seismic intensity, the earthquake detector 20 can detect that a large shaking earthquake has occurred. Here, the predetermined seismic intensity used for determining the occurrence of a large-scale earthquake is, for example, that the user may fall if the user continues to ride on the escalator 1 or that the escalator 1 is difficult to stand properly. It is possible to set a seismic intensity that can cause danger to the user. In other words, a “big earthquake” can be said to be an earthquake with a seismic intensity higher than this. When the earthquake sensor 20 senses that a large shaking earthquake has occurred, it transmits information to that effect to the control device 16. For example, as shown in FIG. 1, the earthquake detector 20 is installed in a housing 22 of the building where the escalator 1 is installed.

  Here, the control device 16 is physically a computer having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. Each of the functions of the control device 16 described above operates various devices in the escalator 1 under the control of the CPU by loading an application program held in the ROM into the RAM and executing it by the CPU. This is realized by reading and writing data in the ROM.

  Next, the operation of the escalator 1 according to this embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing evacuation guidance control performed by the escalator in the present embodiment. The evacuation guidance control flow shown in FIG. 4 is performed by the control device 16 during the operation of the escalator 1.

  In step S01, it is determined whether or not the earthquake detector 20 has detected the occurrence of a large shaking earthquake. If the earthquake sensor 20 detects the occurrence of a large shaking earthquake (Yes in step S01), the process proceeds to step S02. If not (No in step S01), the earthquake sensor 20 detects the occurrence of an earthquake. Wait until.

  In step S02, since it was determined in step S01 that a large shaking earthquake has occurred, the operation of the escalator 1 is stopped due to a dangerous situation in which a large shaking earthquake has occurred via the voice guidance device 18. A voice message is sent to alert the user to alert the user. Thereby, it is possible to alert a person around the escalator 1 not to get on the escalator 1. When the process of step S02 is completed, the process proceeds to step S03.

  In step S03, it is determined whether or not a user or the like exists on the step 5 of the escalator 1 based on the detection result of the human sensor 17. As a result of the determination in step S03, when there is no user or the like on the step 5 of the escalator 1 (No in step S03), the process proceeds to step S04. On the other hand, when the user or the like still exists on the step 5 of the escalator 1 (Yes in Step S03), the process returns to Step S02, and the voice guidance device 18 alerts again, and the people around the escalator 1 are informed. On the other hand, it is further urged not to enter the escalator 1 any more.

  In step S04, since it is determined in step S03 that there is no user or the like on the step 5 of the escalator 1, the motor 21 is controlled to stop the operation of the escalator 1. In this way, by stopping the operation with no user on the step 5, it is possible to avoid the injury of the user due to the operation stop and to safely stop the escalator 1 when a large shaking earthquake occurs. it can. When the process of step S04 is completed, the process proceeds to step S05.

  In step S05, after the operation of the escalator 1 is stopped, evacuation guidance to the evacuation floor is performed for the people around the escalator 1 using the stopped escalator 1. Specifically, the evacuation lights 19a and 19b are turned on to display the evacuation route (the direction of the evacuation floor), and the voice guidance device 18 makes an announcement to guide to the evacuation floor by voice. When the process of step S05 is completed, this control flow is terminated.

  Next, the effect of the escalator 1 according to the present embodiment will be described.

  The escalator 1 according to this embodiment detects the occurrence of a large shaking earthquake, and the escalator 1 moves the steps 5 of the escalator 1 when the earthquake detector 20 detects the occurrence of a large shaking earthquake. When the control device 16 to be stopped and the earthquake detector 20 detect the occurrence of a large shaking earthquake, the user of the escalator 1 is notified of the occurrence of the earthquake, and the control device 16 stops the movement of the step 5. And a notification means (voice guidance device 18, evacuation lights 19a and 19b) for notifying information prompting the user to evacuate.

  Generally, when a large shaking earthquake occurs, when the user of the escalator 1 panics, the user may not know the direction of the evacuation floor and may not be able to determine the evacuation direction appropriately. In the present embodiment, the configuration described above allows the user of the escalator 1 to be notified of the occurrence of the earthquake and guide the evacuation at the time of the occurrence of the earthquake. The direction of evacuation can be presented. Thereby, the escalator 1 of this embodiment can evacuate a user smoothly at the time of an earthquake occurrence.

  Further, in the escalator 1 according to the present embodiment, the voice guidance device 18 as a notification means generates an earthquake for the user of the escalator 1 when the earthquake detector 20 detects the occurrence of a large shaking earthquake. The occurrence of an earthquake is notified by a sound for notifying the user, and after the movement of the step 5 is stopped by the control device 16, evacuation guidance is performed by a voice prompting the user to evacuate.

  With this configuration, it is possible to make the user aware of the occurrence of the earthquake by voice and prompt the evacuation guidance, so that necessary information is audibly presented to the user of the escalator 1 and the user's Anxiety can be removed more suitably, and the user can be more clearly aware of the occurrence of an earthquake and the direction of evacuation, and the user can be evacuated safely.

  Further, in the escalator 1 according to the present embodiment, the evacuation lights 19a and 19b as notification means present the evacuation direction to the user after the movement of the step 5 is stopped by the control device 16. With this configuration, the evacuation direction can be visually presented to allow the user to recognize the evacuation direction more clearly, and the user can be evacuated safely. Moreover, when the whole building where the escalator 1 is installed at the time of an earthquake occurs, the inside of the building becomes dark, and trying to evacuate using the escalator 1 may be dangerous because it is difficult to see the feet. In the present embodiment, the field of view can be secured by irradiating the step 5 with the evacuation lights 19a and 19b, and thus the user can be evacuated safely even in such a situation.

  As mentioned above, although embodiment of this invention was described, said embodiment is shown as an example and is not intending limiting the range of invention. The above embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. The above-described embodiments and modifications thereof are included in the invention described in the scope of claims and the equivalents thereof, as long as they are included in the scope and spirit of the invention.

  In the said embodiment, although the escalator 1 was mentioned and demonstrated as an example of the passenger conveyor which operate | moves so that several steps 5 connected endlessly may move around, this embodiment is not restricted to the escalator 1, a moving walkway, etc. The same applies to other types of passenger conveyors.

  In the above embodiment, “large earthquake of earthquake” is taken as an example of the disaster, and the configuration in which the occurrence is detected by the earthquake detector 20 is exemplified. However, disasters other than earthquakes are detected instead of the earthquake detector 20. Instead of a possible disaster sensing means, the above-described evacuation guidance control may be implemented according to the occurrence of a disaster sensed by the disaster sensing means, or a plurality of types of disaster sensing means may be combined.

  Moreover, in the said embodiment, when the earthquake detector 20 provided in the escalator 1 detected generation | occurrence | production of a big earthquake, it illustrated the structure which notifies a user about the occurrence of an earthquake and evacuation guidance. A thing other than the earthquake detector 20 may be used. For example, it is good also as a structure which monitors the occurrence of the earthquake of the installation place of the escalator 1 in the observation station etc. of the escalator 1 outside. In this case, when an earthquake occurrence is detected at an observation station or the like, information to that effect is transmitted to the escalator 1, and the escalator 1 notifies the user of the occurrence of an earthquake and evacuation guidance in response to the reception of the information.
