Description

  The present invention relates to a passenger conveyor, and more particularly, to a passenger conveyor having a communication suppression function for suppressing communication performed by a mobile communication terminal owned by the passenger.

  Doing walking while operating a mobile communication terminal such as a mobile phone or a smartphone, or walking while viewing information such as an e-mail or a homepage displayed on the mobile communication terminal may cause an accident. Therefore, it is generally considered that the manner is violated (in the following, operating the mobile communication terminal and viewing information displayed on the mobile communication terminal are collectively referred to as “use” of the mobile communication terminal).

  For example, by using a mobile communication terminal while walking, the user enters the railroad crossing without knowing the train's arrival at the station's home without noticing the train's entry, or unknowingly enters the railroad to the train A catastrophe has happened. Accidents caused by so-called "while use" represented by use of a mobile communication terminal while walking are not limited to railway accidents. In passenger conveyors such as escalators and moving walkways, if the passenger in use is using a mobile communication terminal, for example, there is a risk that an accident may occur in which the passenger stumbles on a step and falls or contacts another passenger. is there. In particular, in an escalator, a passenger using a mobile communication terminal while on board will not be transported safely because he does not grasp the handrail by hand. If the operator does not grasp the handrail while riding, for example, when the escalator suddenly stops due to the operation of a safety device or a power failure, the passenger may fall or fall.

  In order to prevent an accident at the time of congestion or the like, there is a passenger conveyor that carries out a broadcast to alert the passengers (see Patent Document 1). In such a passenger conveyor, in addition to a broadcast for alerting passengers, a broadcast for requesting the passengers to stop or cancel the use of the mobile communication terminal while on board can be used to It is conceivable to suppress the occurrence of accidents resulting from use.

Unexamined-Japanese-Patent No. 6-305673

  However, even if a broadcast is issued to request passengers to stop or stop using the mobile communication terminal while the passenger conveyor is on board, the passengers who ignore such a request and do not stop using the mobile communication terminal There will be a significant percentage of passengers starting to use the mobile communication terminal while on board.

  The present invention solves the problems described above, and an object thereof is to effectively suppress the use of a mobile communication terminal by a passenger while the passenger conveyor is on board.

  The passenger conveyor according to the present invention comprises a plurality of treads connected in an endless fashion, a passenger detection means for detecting passengers on board, and a communication for suppressing the communication function of the mobile communication terminal by radiating communication jamming waves into space. A passenger conveyor including a restraining means, wherein the communication restraining means determines the presence or absence of a passenger using the passenger detection means, and emits the communication jamming wave while it is determined that a passenger is present. The range in which communication of the mobile communication terminal is suppressed by the communication disturbance radio wave is characterized by including a region located above the row of treads located on the sending side among the plurality of treads.

  The passenger conveyor of the present invention may further include notification means for notifying the passenger that the communication function of the mobile communication terminal is inhibited while it is determined that the passenger is present.

  The passenger conveyor of the present invention may determine the presence or absence of a passenger using the passenger detection means, and change the operation state of the plurality of treads according to the presence or absence of the passenger.

  The combination of a plurality of passenger conveyors according to the present invention is a combination of a plurality of passenger conveyors including a plurality of footboards in which each passenger conveyor is endlessly coupled and moved, and detects a passenger boarding each passenger conveyor. The passenger detecting means and the communication inhibiting means for radiating the communication interference radio wave to the space to suppress the communication function of the mobile communication terminal are provided, and the communication inhibiting means uses at least one of the passenger detecting means. While it is determined that the passenger is present in the passenger conveyor, the communication disturbance radio wave is emitted, and a plurality of passenger conveyors are provided in a range where the communication function of the mobile communication terminal is suppressed by the communication disturbance radio wave It is characterized in that an area located above the row of treads located on the feed side among the treads is included.

  According to the present invention, while the passengers are on the passenger conveyor, the communication function of the mobile communication terminal is suppressed by the communication interference in the area located above all the treads located on the sending side. The use of the mobile communication terminal related to the communication function or activating the communication function (for example, a call, transmission of an e-mail, update or change of a home page, etc.) by a passenger on board is effectively suppressed. According to the present invention, an accident caused by "while using" the mobile communication terminal is suppressed by the passenger conveyor by the fact that the mobile communication terminal can not be used, but particularly when the present invention is applied to an escalator It is more effective in that the situation in which the driver does not grasp the handrail is suppressed.

  By providing the notification means, it is possible to prevent passengers from being confused due to the inability of the mobile communication terminal possessed to communicate.

  By applying the present invention to a type of passenger conveyor in which the operation state of a plurality of treads is changed according to the presence or absence of a passenger, the present invention can be efficiently performed using the passenger detection means possessed by this type of passenger conveyor. Can be implemented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an outline of an escalator 1 which is a first embodiment of a passenger conveyor according to the present invention. The escalator 1 includes an escalator main body 11, a motor 21, a braking device 23, and a control device 25. The escalator 1 is installed to transport passengers from the lower floor A to the upper floor B of a facility such as a station or department store. .

  The escalator main body 11 includes a plurality of treads 13 which are endlessly connected and move, a chain 15 to which the treads 13 are attached, a handrail 17 used as a handrail, and the like. The electric motor 21 operates by receiving supply of electric power from a commercial power source or the like (not shown), and the output of the electric motor 21 is transmitted to the escalator main body 11 via a reduction gear 27 composed of gears and the like. As a result, the escalator 1 is operated to transport the passengers from the lower floor A to the upper floor B by circulating the treads 13 and the hand rails 17. In FIG. 1, among the treads 13 provided on the chain 15, the tread plate 13 is located on the feed side or the transport side (that is, moved in the transport direction of the passengers) and exposed upwards so that the passengers can be mounted. Of the row of treads 13, only three treads 13 are shown (also in FIGS. 2, 3, 5 and 6).

  The braking device 23 includes, for example, a brake disk provided on an output shaft or the like of the electric motor 21 and a brake pad which is brought into sliding contact with the brake disk as appropriate (both are not shown). The motor 21 and the braking device 23 are controlled by the controller 25 for the escalator main body 11. The control device 25 is configured using, for example, a microcomputer.

  The escalator 1 determines the presence or absence of a passenger using a passenger detection means, and changes the operation state of the plurality of treads 13 according to the presence or absence of the passenger. In the present embodiment, the passenger detection means is the human sensor 31 installed on the landing side of the escalator 1, and when the human sensor 31 detects a passenger, it sends a notification to that effect to the control device 25. When it is determined that there is no passenger, the tread 13 is not in motion and is in a pause or stop state. When the notification that the passenger has been detected is received from the human sensor 31, the control device 25 drives the electric motor 21 to start or restart the circulation travel of the tread board 13 which has been in the inactive state.

  FIG. 2 is a plan view schematically showing the escalator main body 11. A pair of poles 33, 33 are spaced apart in the machine width direction of the escalator main body 11 and erected on the landing side of the escalator 1, and the human sensor 31 is provided on the poles 33, 33. The human sensor 31 includes a light emitting unit 35 provided on one pole 33 and a light receiving unit 37 provided on the other pole 33. For example, the infrared light L is constantly emitted from the light emitting unit 35 toward the light receiving unit 37, and the infrared light L is temporarily blocked by the passage of a passenger, thereby passing between the poles 33, 33 and boarding. The presence of a passenger is detected.

  If the control device 25 determines that there is no passenger of the escalator 1, the control device 25 operates the braking device 23 to stop the circulation travel of the tread 13. For example, when a predetermined time elapses without detecting the intrusion of a further passenger from the time when the human sensor 31 detects the intrusion of a passenger, the control device 25 determines that the passenger of the escalator 1 does not exist. . The specified time is set based on the time it takes for passengers passing between the poles 33 and 33 of the escalator 1's platform to board the escalator 1 and the escalator 1 transports the passengers to the landing floor B on the upper floor. Be done.

  The feature of the passenger conveyor according to the present invention is that the passenger conveyor is provided with a communication inhibiting means for suppressing communication function of the mobile communication terminal by radiating communication interference radio waves into space. Then, the communication inhibiting means determines the presence or absence of the passenger using the passenger detecting means, and emits the communication jamming wave while it is determined that the passenger of the passenger conveyor is present.

  The escalator 1 of the present embodiment includes the communication suppression device 51 corresponding to the communication suppression means according to the present invention, and when the passenger of the escalator 1 owns a mobile communication terminal such as a mobile phone or a smartphone, By suppressing the communication of the mobile communication terminal while on board, the use of the mobile communication terminal by the passenger is suppressed. The communication suppression device 51 includes a control unit 53, jamming radio wave generation units 55 a-f and notification units 57 a-b connected to the control unit 53.

  Each of the jamming signal generation units 55a-f is disposed near or in the vicinity of the escalator main body 11, and is a base station of a mobile communication network (mobile telephone network or mobile packet communication network) that accommodates mobile communication terminals owned by passengers. A communication interference wave of the same frequency as that of the communication signal transmitted from (not shown) is radiated into space. An area (hereinafter referred to as a communication suppression area) capable of receiving communication jamming radio waves emitted from the jamming radio wave generating parts 55a-f at an electric field strength higher than a predetermined threshold value corresponding to each of the jamming radio wave generating parts 55a-f is It is formed. When the mobile communication terminal of the passenger is disposed within any of these communication suppression areas, the mobile communication terminal also receives a communication interference wave in addition to the communication signal emitted by the base station. The communication interference radio waves are mixed, and the mobile communication terminal is included in the communication signal, and can not specify various information necessary for communication with the base station, and communication between the mobile communication terminal and the base station is not possible. It becomes possible.

  Since the frequency of the communication signal radiated from the base station of the mobile communication network differs depending on the operator of the mobile communication network, each of the jamming signal generation units 55a-f is assumed for the mobile communication terminal owned by the passenger. It is preferable to emit communication jamming waves at a plurality of frequencies respectively corresponding to the frequencies (originated from the base station) of all the mobile communication networks. In addition, even if communication jamming radio waves are emitted not at the frequencies of all the mobile communication networks but at a plurality of frequencies respectively corresponding to the frequencies of several mobile communication networks of which the number of users is higher, the movement by the passengers of escalator 1 The use of the communication terminal will be effectively suppressed by the present invention (although in rare circumstances the communication function of the mobile communication terminal not supported by the communication interference wave can not be suppressed).

  FIG. 3 shows that a passenger of the escalator 1 is detected by the human sensor 31, and communication jamming waves R are emitted from each of the jamming wave generation units 55a-f. In the present embodiment, each of the jamming wave generating units 55a-f includes a directional antenna, and the communication jamming wave R is radiated to space from the directivity antenna and each of the jamming wave generating units 55a-f is A corresponding communication suppression area is generated. In the present embodiment, the jamming signal generation units 55a-f are arranged horizontally at different heights above the landing and landing area of the escalator 1 and the escalator main body 11, and each jamming signal is Communication jamming radio waves R are emitted downward from the generating units 55a-f. The interfering radio wave generating units 55b-e (directive antennas) disposed above the escalator main body 11 have the directivity of the interfering radio wave generating units 55a above the landing of the escalator 1 in consideration of the inclination of the escalator main body 11). The antenna is disposed at an inclined position with respect to the

  The jamming signal generation units 55a-f are arranged and configured such that the communication suppression areas of the jamming signal generation units 55a-f partially overlap. The communication deterrence area as a whole is located above (or on the feed side of) the row of treads 13 located on the feed side among the plurality of treads 13 of the escalator main body 11, and the row of treads 13 exposed on the upper side In the present embodiment is configured to include an assumed area Z in which it is assumed that the mobile communication terminal possessed by the passenger of the escalator 1 is present. ing.

  In FIG. 2, FIG. 3, and FIG. 5, the assumed area Z is indicated by an alternate long and short dash line. The assumed area Z is, for example, located on the feed side at any time while the tread plate 13 is traveling, and faces upward for each of the tread plates 13 constituting the row of the tread plates 13 exposed to the upper side. Is defined so as to include a rectangular parallelepiped space Y defined by translating the upper surface of each rectangular or substantially rectangular exposed in the vertical direction from the first distance H1 to the second distance H2 (see FIG. 3) . The first distance H1 and the second distance H2 are defined so that the mobile portable terminal carried by the passenger on the tread 13 is present in the space Y corresponding to the tread 13. For example, the first distance H1 is 20 The second distance H1 is about 180 to 200 cm to about 30 cm. The assumed area Z is slightly larger than the width of the upper surface W of the footboard 13 in the machine width direction of the escalator main body 11 (see FIG. 2) . In this embodiment, as shown in FIG. 2 and FIG. 3 etc., the assumed area Z is near the landing of the escalator 1 (more specifically, in the vicinity of the poles 31 and 31) and the vicinity of the landing of the escalator 1. It is decided to extend to and.

  The number of jamming wave generation units 55a-f, the output of communication jamming waves in each jamming wave generation unit 55a-f, the range of the communication suppression area, and the relative position of the escalator 1 to the landing and landing area and the escalator main body 11 , In addition to the assumed area Z, it is determined based on the structure of the escalator main body 11 and the structure of the facility where the escalator 1 is provided.

  The control unit 53 is, for example, a programmable logic controller. For example, the control unit 53 includes a CPU, a volatile memory, and a non-volatile memory (none of which are shown). The non-volatile memory of the control unit 53 may be, for example, an EPROM, an EEPROM, or a flash ROM.

  In the non-volatile memory, in response to the detection of a passenger boarding the escalator main body 11 by the human sensor 31, suppression of the communication function of the mobile communication terminal is started, and it is determined that no passenger is present in the escalator main body 11. A communication suppression program that causes the control unit 53 of the communication suppression device 51 to execute the communication suppression processing of the communication suppression device 51 that cancels the suppression is stored in advance.

  The volatile memory of the control unit 53 is, for example, a RAM. The volatile memory is used as a work area when executing the communication suppression program, and stores data to be referenced and / or updated in the process of executing the communication suppression program. The CPU of the control unit 53 reads the communication suppression program from the non-volatile memory to the volatile memory, for example, in response to the power-on of the communication suppression device 51, and starts execution. The communication suppression process executed by the control unit 53 in accordance with the communication suppression program will be described later.

  In the present embodiment, the communication suppression apparatus 51 includes two notification units 57a-b corresponding to the notification unit of the present invention, the notification unit 57a is disposed above the landing of the escalator 1, and the notification unit 57b is The escalator 1 is disposed on the landing side of the escalator 1 above the escalator main body 11. Each of the notification units 57a-b, for example, includes an A / D converter for converting digital audio data sent from the control unit 53 into an analog audio signal, an amplifier for amplifying an analog audio signal, and an analog amplified by the amplifier. A speaker is provided which converts an audio signal into audio and amplifies it.

  Each of the notification units 57a-b notifies the passengers of the escalator 1 by voice that the mobile communication terminal can not be used while on board. In the non-volatile memory of the control unit 53, for example, voice data of voice “can not communicate with a mobile communication terminal such as a mobile phone or a smartphone while riding on an escalator” is stored. When a passenger passing between the poles 33, 33 is detected by the human sensor 31, the control unit 53 periodically transmits the voice data to the notification units 57a-b, and the jamming signal generation units 55a-f During operation, the above sound is periodically reproduced from the speakers of the notification units 57a-b.

  Next, the communication suppression processing using the communication suppression apparatus 51 in the escalator 1 will be specifically described. FIG. 4 is a flowchart showing the flow of the communication suppression process performed by the control unit 53 of the communication suppression apparatus 51. First, (the CPU of) control unit 53 determines whether or not a passenger who gets on escalator 1 is detected by human sensor 31 (step S010). The human sensor 31 provided on the poles 33 and 33 of the escalator 1 landing passes the space between the poles 33 and 33 so that the human sensor 31 (more specifically, the light receiving portion 37 of the human sensor 31). When the notification that the infrared light from the light emitting unit 35 received by the light receiving unit 37 is interrupted, that is, the notification that the passenger has been detected is received from the light receiving unit 37, the human detection sensor 31 determines that the passenger is detected. While the determination result in step S010 is No, the step S010 is repeated.

  If the result of the determination in step S010 is Yes, the escalator 1 starts to notify the passenger that the mobile communication terminal can not be used (step S020). In step S020, the control unit 53 operates the notification units 57a and 57b, and sends the above-described notification audio data stored in the non-volatile memory to the notification units 57a and 57b. Then, by the notification units 57a-b, a voice that "can not communicate with a mobile communication terminal such as a mobile phone or a smartphone while riding on the escalator" is reproduced. The reproduction of the voice is repeatedly performed in a predetermined cycle.

  If the determination result in step S010 is YES, the control unit 53 of the communication suppression apparatus 51 executes step S020, but on the other hand, the control device 25 of the escalator 1 receives the notification from the human sensor 31. The circulation travel of the tread 13 is started.

  After step S020, control unit 53 activates jamming signal generation units 55a-f (step S030). By execution of step S030, communication interference radio waves R are emitted from each of the interference radio wave generating units 55a to 55f. The control unit 53 is provided with a time measurement counter (not shown), and after step S030, the control unit 53 resets the value Tm of the counter to 0 (step S040), and counts the time in the counter. It is started (step S050).

  After step S <b> 050, the control unit 53 determines whether a passenger boarding the escalator 1 is detected by the human sensor 31 as in step S <b> 010 (step S <b> 060). When the determination result of step S060 is Yes, step S040 and step S050 are performed again. If the determination result in step S060 is No, the control unit 53 determines whether the value Tm of the counter exceeds a predetermined threshold (step S070). If the determination result of step S070 is No, step S060 is executed again.

  The predetermined threshold is determined in consideration of the time that it is assumed that it takes the passengers to pass the poles 33, 33, get on the escalator main body 11 and be transported to the landing, for example, It is set to the same time or a time slightly longer than the time. Further, the threshold value is the same value as the above-described predetermined time at which the controller 25 of the escalator 1 determines that there is no passenger at the escalator 1 or a value close thereto.

  If it is determined YES in step S 070, it can be determined that there are no passengers on board the escalator 1 and passengers trying to board the escalator 1 after passing the poles 33 and 33, the control unit 53 The timing by the counter is ended (step S 080), and the operation of the jamming signal generation units 55 a-f is stopped (step S 090). After step S090, the control unit 53 stops the operation of the notification units 57a and 57b to stop the notification to the passenger by voice (step S100). After step S100, step S010 and the subsequent steps are executed again.

  If the determination result in step S 070 is YES, the control unit 53 of the communication suppression apparatus 51 executes steps S 080 to S 100, but on the other hand, the control apparatus 25 of the escalator 1 includes The circulation travel of the tread 13 is stopped at the same timing as the stop of the notification parts 57a and 57b or at some time before or after that.

  After the passenger is detected in step S010, if the next passenger is not detected by the human sensor 31 within the predetermined threshold after step S050 is executed, steps S010 to S100 return from step S060 to step S040. Run without In the case where the next passenger is detected by the human sensor 31 within a predetermined threshold after the passenger is detected in step S010, the process returns from step S060 to step S040, and the value Tm of the counter is reset to 0, In step S050, clocking is started. Thereafter, when the next passenger is not detected by the human sensor 31 within the predetermined threshold, steps S060 to S100 are executed without returning from step S060 to step S040. If the next passenger is detected by the human sensor 31 within the predetermined threshold, the process returns from step S060 to step S040, the value of the counter Tm is reset to 0, and step S050 and subsequent steps are performed. To be executed.

  For example, in FIG. 1, when the passenger P having the mobile communication terminal X shown on the left side of the poles 33, 33 of the landing of the escalator 1 passes between the poles 33, 33, the passenger P detects the human sensor 31 Is detected, and steps S010 to S050 shown in FIG. 4 are executed. From the notification units 57a-b, voices repeatedly notifying the passenger P that the mobile communication terminal can not be used while on board are repeatedly reproduced. As shown in FIG. 3, when the mobile communication terminal X of the passenger P who travels to the escalator main body 11 enters at least the assumed area Z by the operation of the jamming signal generation units 55a-f, from the jamming signal generation unit 55a Communication of the mobile communication terminal X is suppressed by receiving the radiated communication interference radio wave R. Further, in response to the detection of the passenger P by the human sensor 31, the escalator 1 starts the operation and the tread 13 starts the circulation.

  The passenger P having the mobile communication terminal X is placed on a certain tread 13 and moves from the lower floor A to the upper floor B as the tread 13 travels. FIG. 5 shows the pattern of the passenger P being transported by the escalator 1. As shown in FIG. 5, the mobile communication terminal X of the passenger P is in the assumed area Z during the boarding or transportation, and the communication jamming R radiated from at least one of the jamming radio generation units 55a-f is By receiving, the communication function of the mobile communication terminal X is suppressed.

  For example, when the next passenger is not detected by the human sensor 31 and the passenger P arrives at the landing of the escalator 1, it is determined No in step S060, and further, the value Tm of the counter is predetermined in step S070. It is determined that the threshold value of the threshold value is exceeded, and step S080 and further step S090 are executed. As a result, the jamming radio wave generation unit 55a-f is stopped to terminate the emission of the communication jamming radio wave R, step S100 is executed, the notification unit 57a-b is stopped, and the sound reproduction is ended. Further, the control device 25 of the escalator 1 stops the circulation travel of the tread 13.

  Thus, in the present embodiment of the present invention, the use of the mobile communication terminal by the passenger while on board is linked to the operation of the escalator 1 which detects the passenger using the human sensor 31 and changes the driving state. It is effectively suppressed.

  In the above embodiment, although the jamming radio wave generation units 55a-f radiate communication jamming radio waves via the directional antenna, if permitted by the relationship of the facility where the escalator 1 is installed (for example, When there is a large dead space around the escalator 1), a jamming wave generator that radiates communication jamming waves isotropically may be used in the embodiment of the present invention. Also, the directivity and the isotropic jammer generation unit may be used in combination.

  In the above embodiment, the jamming signal generation units 55a-f are disposed above the landing and landing of the escalator 1 and above the escalator main body 11, but as described above, in the present invention, the jamming occurs. The arrangement place of the radio wave generator is not limited to the above embodiment. For example, a plurality of pairs of disturbing radio wave generating portions disposed opposite to each other on the left and right of the escalator main body 11 may be provided along the transport direction of the escalator main body 11.

  In the above embodiment, the notification units 57a-b tell the passengers by voice that the mobile communication terminal can not be used while boarding, but the notification units 57a-b have a display means, It may be shown visually to the passengers (displaying the letters). In addition, a notification unit that makes a notification by voice and a notification unit that makes a visual notification may be used in combination.

  In the above embodiment, the jamming radio wave generation units 55a-f and the notification units 57a-b are operated in conjunction with the operation of the escalator 1 to start or stop the circulation traveling of the footboard 13 based on the detection of the passenger by the human sensor 31. However, the present invention may be applied to an escalator in which the tread 13 constantly circulates and to an escalator in which a low speed operation is performed when it is determined that a passenger is not aboard.

  In the above embodiment, the passenger detecting the passenger boarding the escalator 1 is detected by using the human sensor 31 provided on the pole 33, 33 and provided with the light emitting unit 35 and the light receiving unit 37. It may be a human sensor. Moreover, the detection means of the passenger in this invention is not limited to this kind of human sensor, Any means that can detect a passenger may be used. For example, a weight sensor provided below the boarding board of the escalator's landing may be used to detect the passenger, and the passenger may be detected based on fluctuations in the current of the motor driving the escalator.

  Although the escalator 1 of the above-mentioned embodiment explains the example of application of the present invention to an ascending escalator, it is clear that the present invention is applicable also to a descending escalator. Further, the present invention may be applied to a combination of a plurality of escalators, and in this case, the communication inhibiting means according to the present invention is determined that a passenger is present in at least one of the escalators of the plurality of escalators. It is located above the row of treads located on the sending side among the plurality of treads provided in each passenger conveyor within a range in which communication jamming radio waves are emitted and communication of the mobile communication terminal is suppressed by the communication jamming radio waves. An area may be included.

It comprises units 55a-f and notification units 57a-b (see FIG. 1). However, in the second embodiment, (the light receiving unit 37 'of) the human sensor 31' is connected to the control unit 53, and further, the arrangement and configuration of the jamming wave generating units 55a-f and the notification units 57a-b are changed. And the change of the communication suppression process which the control part 53 performs is made.

  In the second embodiment of the present invention, it is assumed that the above-described assumed area Z is set for the uplink escalator 1 and that the mobile communication terminal possessed by the passenger of the downlink escalator 1 ′ also exists for the downlink escalator 1 ′. An assumed assumed area Z 'is set. The assumed area Z ′ may be determined in the same manner as the assumed area Z. For example, the escalator main body 11 ′ is positioned on the feed side at an arbitrary time while the tread plate 13 ′ is traveling, For each of the treads 13 'that make up the row of exposed treads 13', the upper surface of each rectangular or substantially rectangular surface exposed upward is the first distance as mentioned above with respect to the assumed area Z in the vertical direction It is determined to include a rectangular parallelepiped space (corresponding to the space Y) defined by translating from H1 to the second distance H2. The assumed area Z 'is slightly larger than the width of the upper surface W' of the tread 13 'in the machine width direction of the escalator main body 11'. In the second embodiment, as shown in FIG. 6, the assumed area Z includes the landing of the downward escalator 1 ′ (more specifically, the vicinity of the poles 31 ′ and 31 ′) and the downward movement of the downward escalator 1 ′. It is decided to extend to the vicinity of the field.

  As in the first embodiment, the jamming radio wave generation units 55a-f are arranged and configured such that the communication suppression areas of the jamming radio wave generation units 55a-f partially overlap. The communication deterrence area as a whole includes a first area located above the row of treads 13 located on the sending side among the plurality of treads 13 of the escalator main body 11, and a feed among the plurality of treads 13 'of the escalator main body 11'. And a second area located above the row of footboards 13 'located on the side, wherein the first area includes the assumed area Z and the second area includes the assumed area Z'.

  FIG. 7 is a flowchart showing the flow of the communication suppression process performed by the control unit 53 of the communication suppression apparatus 51 in the second embodiment of the present invention. Steps S110 to S200 shown in FIG. 7 correspond to steps S010 to S100 shown in FIG. 4 respectively, but in steps S110 and S160, the human sensor 31 of the escalator 1 and the people of the escalator 1 ' This is different from the communication suppression process in the first embodiment in that the control unit 53 determines whether the passenger who has boarded is detected by any of the sensors 31 ′. With such a configuration, in the second embodiment of the present invention, the control unit 53 of the communication suppression apparatus 51 determines that the passenger is on at least one of the upward escalator 1 and the downward escalator 1 ′. While being turned on, the jamming signal generation units 55a-f and the notification units 57a-b operate.

  As described in relation to the first embodiment, the controller 25 of the ascending escalator 1 starts or restarts the cyclic traveling of the tread 13 when the passenger is detected by the human sensor 31, and the passenger of the escalator 1 If it is determined that there is not, the circulation travel of the tread 13 is stopped. The controller (not shown) of the downward escalator 1 'also starts or restarts the circulation travel of the tread 13' when the passenger is detected by the human sensor 31 'in the same manner as the upward escalator 1. If it is determined that there is no passenger 1 ', circulation travel of the tread 13' is stopped. Therefore, in the second embodiment, the interference radio wave generation unit 55a-f and the notification unit 57a substantially correspond to a period in which the cyclic traveling of the tread plate is continuously performed by at least one of the ascending escalator 1 and the descending escalator 1 '. -B works.

  Although it is also possible to provide the communication suppression device 51 in each of the upward escalator 1 and the downward escalator 1 ′, the second embodiment communicates the mobile communication terminals of the passengers of both the upward escalator 1 and the downward escalator 1 ′. , Which is suppressed by one communication suppression apparatus 51, which is preferable in terms of cost reduction.

  1, 2, 3, 5 and 6 are for explaining the present invention, and various constituent elements of the escalator 1 of the embodiment such as the footboard 13 and the jamming wave generating units 55 a-f. The shape, relative position, dimensional ratio, etc. of the area Z are not strictly reflected. In addition, in the communication suppression process shown in the flowcharts of FIGS. 4 and 7, it is noted that the order of some steps may be changed (for example, step S040 may be executed after step S030).

  The passenger conveyor to which the present invention is applied is not limited to the escalator, and the present invention may be applied to, for example, a moving sidewalk. Further, the combination of the plurality of passenger conveyors to which the present invention is applied is not limited to the combination of the plurality of escalators. For example, the present invention may be applied to a combination of a plurality of moving walkways.
