And a microcomputer 67 that performs output control of a step operation control signal under the control of the operation control circuit 68.

  Similar to the microcomputers 27 and 45, the microcomputer 67 includes a CPU (not shown), a RAM (not shown) for holding data, and a ROM (not shown) in which a control program for the communication control device 60 is stored. Has been.

As shown in FIG. 5, the operation control circuit 68 includes three relays 68 a to 68 c and a relay driver 72 configured to be able to control the states of the relays 68 a to 68 c.
Each of the relays 68a to 68c has a relay coil 69a to 69c and a normally open contact 70a to 70c, respectively.

Relay coils 69 a to 69 c are connected between a low voltage terminal 73 of a power source (not shown) and an output terminal (not shown) of the relay driver 72. At this time, one end of each of the relay coils 69 a to 69 c is connected to each of separate output terminals of the relay driver 72. The relay driver 72 is connected to a high-voltage terminal 74 of the power source, and can control energization to and interruption of the relay coils 69a to 69c.
The relay driver 72 is communicably connected to the microcomputer 67, and the relay driver 72 controls energization and disconnection of the relay coils 69 a to 69 c based on a code received from the microcomputer 67.

  Further, the normally open contacts 70a to 70c of the relays 68a to 68c are connected between the escalator control panel 25 and the high voltage terminal 74 of the power source. At this time, each of the normally open contacts 70 a to 70 c is connected to a respective separate input port of the microcomputer 27 of the escalator control panel 25. Thereby, the outputs of the normally open contacts 70a to 70c are electrically switched between High and Low in accordance with the energization state of the relay coils 69a to 69c.

That is, when the relay coils 69a to 69c are energized, the high voltage terminal 74 of the power source and the escalator control panel 25 are electrically connected, and an electrically high signal is input to the escalator control panel 25 from the normally open contacts 70a to 70c. The
Further, when the energization to the relay coils 69 a to 69 c is interrupted, the energization path between the high voltage terminal 74 of the power source and the escalator control panel 25 is interrupted, and an electrically low signal is input to the escalator control panel 25. .

  Here, an electrically high or low signal output from each of the normally open contacts 70a to 70c is an ascending operation control signal, a descending operation control signal, and a stop control signal, and these are collectively referred to as a step operation control signal. And That is, the escalator control panel 25 is configured to be able to input a step operation control signal output from the communication control means 66.

  As shown in FIGS. 4 and 5, the key switch 80 has a movable contact 83 that rotates in conjunction with the rotation operation of the key 82 inserted into the key hole 81, and the movable contact 83 according to the arrangement position of the movable contact 83. And three fixed contacts 84 a to 84 c configured to be connected to 83.

  The movable contact 83 and the fixed contacts 84 a to 84 c are incorporated in the operation control circuit 68. At this time, the movable contact 83 is connected to the high voltage terminal 74 of the power source. The movable contact 83 is a remote control position that is set when the operation of the step 16 is controlled by the remote controller 30, a stop position for stopping the travel of the step 16, and an operation for raising the step 16. The ascending operation position and the descending operation position for causing the step 16 to descend are configured.

  At this time, the movable contact 83 is configured to be connected to each of the fixed contacts 84a to 84c in response to the position of the movable contact 83 taking the stop position, the ascending operation position, and the descending operation position, respectively. Has been. Further, when the position of the movable contact 83 is at the remote control position, the movable contact 83 is not connected to any of the fixed contacts 84a to 84c.

  Further, around the key hole 81, the position of the movable contact 83 is “remote control”, “stop”, “lift” so that the position of the movable contact 83 is in the remote control position, the stop position, the ascending operation position, and the descending operation position. "And" Descent "are displayed. When the position of the key hole 81 is adjusted so that “remote control”, “stop”, “up” and “down” indications are displayed on the extension line in the longitudinal direction of the key hole 81, the movable contacts 83 are respectively The remote control position, the stop position, the ascending operation position, and the descending operation position are arranged.

In addition, each of the fixed contacts 84a to 84c is connected to each of energization paths between the relay driver 72 and the relay coils 69a to 69c by electric wiring.
Thus, when the key 82 is stopped at the stop position, the relay coil 69a is energized, and when the key 82 is stopped at the ascending operation position, the relay coil 69b is energized and the key 82 is stopped at the descending operation position. Sometimes, the relay coil 69c is energized. That is, when the rotation of the key 82 is stopped when the key 82 is set to the stop position, the ascending operation position, and the descending operation position, the escalator control panel 25 is electrically connected to each of the normally open contacts 70a to 70c. In other words, a high signal is input. That is, it is possible to arbitrarily switch High and Low of the step operation control signals output from the normally open contacts 70a to 70c also by rotating the key 82.

  In the key switch 80, the key 82 inserted into the key hole 81 can be removed from the key hole 81 only when the movable contact 83 is at the remote control position. That is, when the key 82 is removed from the key hole 81, the movable contact 83 is always arranged at the remote control position.

The second wireless communication module 65 has the same configuration as the first wireless communication module 38 and can communicate with the first wireless communication module 38.
At this time, when the distance between the first wireless communication module 38 and the second wireless communication module 65 is within a range of, for example, 1 m, the first wireless communication module 38 and the second wireless communication module 38 can communicate with each other. The intensity of the signal transmitted from the communication module 65 is set.

Next, the operation of the remote controller 30 will be described.
First, ON / OFF switching control of the operation flag by the microcomputer 45 of the remote controller 30 will be described with reference to FIG.
In FIG. 6, steps 101 to 104 are denoted as S101 to S104 for convenience of explanation.
In the initial state, it is assumed that the operation flag is OFF.
In step 101, the microcomputer 45 determines whether or not the communication confirmation switch 34 has been pressed.
If the microcomputer 45 determines in step 101 that the communication confirmation switch 34 has not been pressed, step 101 is repeated.
If the microcomputer 45 determines in step 101 that the communication confirmation switch 34 has been pressed, the microcomputer 45 turns on the operation flag (step 102).

In step 103, the microcomputer 45 determines whether or not the communication confirmation switch 34 is pressed.
If the microcomputer 45 determines in step 103 that the communication confirmation switch 34 has been pressed, step 103 is repeated.
If the microcomputer 45 determines in step 103 that the communication confirmation switch 34 has not been pressed, the microcomputer 45 turns off the operation flag and returns to step 101.

  In summary, the microcomputer 45 controls the operation flag ON / OFF so that the operation flag is turned ON only when the communication confirmation switch 34 is pressed.

Next, transmission control of the communication confirmation signal by the microcomputer 45 of the remote controller 30 will be described with reference to FIG. 7. In FIG. 7, steps 201 to 203 are denoted as S201 to S203 for convenience of explanation.

In step 201, the microcomputer 45 determines whether or not the operation flag is ON.
If the microcomputer 45 determines in step 201 that the operation flag is not ON, it repeats step 201.
If the microcomputer 45 determines in step 202 that the operation flag is ON, the microcomputer 45 transmits a communication confirmation signal from the first wireless communication module 38 only once (step 202). The communication confirmation signal is a signal for confirming whether or not the second wireless communication module 65 is within the communication range. Also, “transmission only once” means that transmission is stopped after a minute time transmission.

In step 203, the microcomputer 45 determines whether or not a predetermined time has elapsed since the transmission of the communication confirmation signal.
If the microcomputer 45 determines in step 203 that the predetermined time has not elapsed, step 203 is repeated.
If the microcomputer 45 determines in step 203 that a predetermined time has elapsed, the process returns to step 201.

  In summary, the microcomputer 45 transmits a communication confirmation signal from the second wireless communication module 65 every predetermined time when the communication confirmation switch 34 is continuously pressed.

Next, light emission control of the first LED 41 and the second LED 42 by the microcomputer 45 of the remote controller 30 will be described with reference to FIG.
In FIG. 8, steps 301 to 310 are denoted as S301 to S310 for convenience of explanation.

In step 301, the microcomputer 45 determines whether a communication acceptance signal has been received from the communication control device 60. The communication acceptance signal is a signal transmitted from the second wireless communication module 65 when the microcomputer 67 of the communication control device 60 determines that the communication confirmation signal is received by the second wireless communication module 65, as will be described later. The microcomputer 45 of the remote controller 30 determines that communication with the communication control device 60 is possible by receiving the communication acceptance signal.
If the microcomputer 45 determines in step 301 that a communication acceptance signal has not been received, step 301 is repeated.
If the microcomputer 45 determines in step 301 that the communication acceptance signal has been received, the microcomputer 41 causes the first LED 41 to emit light (step 302). That is, the manager of the escalator 1 (the operator of the remote controller 30) can recognize that the remote controller 30 can communicate with the communication control device 60 by the light emission of the first LED 41.

In step 303, the microcomputer 45 determines whether a normal operation signal has been received from the communication control device 60. As will be described later, the normal operation signal is a signal transmitted from the second wireless communication module 65 when the microcomputer 67 of the communication control device 60 determines that the second wireless communication module 65 has been received by the communication confirmation signal. The microcomputer 45 is notified that the safety switch of the second escalator 1 is not operating.
If it is determined in step 303 that the microcomputer 45 has not received a normal operation signal, the microcomputer 45 proceeds to step 309.
If the microcomputer 45 determines in step 303 that a normal operation signal has been received, the microcomputer 45 causes the second LED 42 signal to emit light (step 304). That is, by the light emission of the second LED 42, the escalator 1 can make the administrator recognize that the safety switch is not operating in a normal state.

In step 305, the microcomputer 45 determines whether or not the communication acceptance signal has been received again within a predetermined time from the reception of the previous communication acceptance signal.
In step 305, when the microcomputer 45 determines that the communication acceptance signal has not been received again, the administrator determines that the manager has left the communication range with the communication control device 60 or has interrupted the operation of the remote controller 30. The light emission of the first LED 41 and the light emission of the second LED 42 are stopped (step 306).
If it is determined in step 305 that the microcomputer 45 has received the communication acceptance signal again, the microcomputer 45 determines whether or not the normal acceptance signal has been received again within a predetermined time from the previous reception of the normal operation signal (step 307).

In step 307, when the microcomputer 45 determines that the normal operation signal has been received again, the microcomputer 45 returns to step 305.
If the microcomputer 45 determines in step 307 that the normal operation signal has not been received again, the microcomputer 45 stops the light emission of the second LED 42 (step 308), and proceeds to step 309.

In step 309, the microcomputer 45 determines whether or not the communication acceptance signal has been received again within a predetermined time from the reception of the previous communication acceptance signal.
If the microcomputer 45 determines in step 309 that the communication acceptance signal has not been received again, the administrator determines that the operation of the remote controller 30 has been stopped by recognizing the operation of the safety switch, and stops the light emission of the first LED 41. Then, the process returns to step 301.

  In summary, the microcomputer 45 emits the first LED 41 and the second LED 42 and receives only the communication acceptance signal when receiving the communication acceptance signal and the normal operation signal at predetermined time intervals. In this case, only the first LED 41 is caused to emit light, and if it is determined that the reception of the communication acceptance signal has not been received for a predetermined time or longer, the emission of the first LED 41 and the second LED 42 is stopped.

Next, transmission control of a step operation command signal by the microcomputer 45 of the remote controller 30 will be described with reference to FIG.
In FIG. 9, steps 401 to 410 are denoted as S401 to S410 for convenience of explanation.

In step 401, the microcomputer 45 determines whether or not the operation flag is ON.
If the microcomputer 45 determines in step 401 that the operation flag is not ON, it repeats step 401.
When the microcomputer 45 determines in step 401 that the operation flag is ON, whether or not the ascending operation command switch 35 of the step 16 is pressed, in other words, ascending operation is selected by the administrator as the operation mode of the step 16. It is determined whether or not it has been done (step 402).

If the microcomputer 45 determines in step 402 that the ascending operation is not selected as the operation mode, the microcomputer 45 proceeds to step 405.
If the microcomputer 45 determines in step 402 that the ascending operation has been selected as the operation mode, the microcomputer 45 determines whether or not the previously transmitted step operation command signal is an ascending operation command signal (step 403). If the microcomputer 45 has not transmitted a step operation command signal, the microcomputer 45 determines that the previously transmitted step operation command signal is not an ascending operation command signal.

In step 403, when the microcomputer 45 determines that the step operation command signal transmitted last time is an ascending operation command signal, the microcomputer 45 returns to step 401.
If the microcomputer 45 determines in step 403 that the previously transmitted step operation command signal is not an ascending operation command signal, the microcomputer 45 transmits the ascending operation command signal only once (step 404), and returns to step 401.

In step 405, the microcomputer 45 determines whether or not the descending operation command switch 36 of the step 16 has been pressed, in other words, whether or not the descending operation has been selected as the operation mode of the step 16 by the administrator.
If the microcomputer 45 determines in step 405 that the descent operation is not selected as the operation mode, the microcomputer 45 proceeds to step 408.

In step 405, when the microcomputer 45 determines that the descent operation is selected as the operation mode, the microcomputer 45 determines whether or not the previously transmitted step operation command signal is a descent operation command signal (step 406). In addition, the microcomputer 45 judges that the step operation command signal transmitted last time is not a descending operation command signal when the step operation command signal has never been transmitted.
If the microcomputer 45 determines in step 406 that the previously transmitted step operation command signal is a descending operation command signal, the microcomputer 45 returns to step 401.
If the microcomputer 45 determines in step 406 that the previously transmitted step operation command signal is not a descending operation command signal, the microcomputer 45 transmits the descending operation command signal only once (step 407) and returns to step 401.

In step 408, the microcomputer 45 determines whether or not the stop command switch 37 of the step 16 is pressed, in other words, whether or not the stop is selected as the operation mode of the step 16 by the administrator.
If the microcomputer 45 determines in step 408 that the stop is not selected as the operation mode, the microcomputer 45 returns to step 401.
If the microcomputer 45 determines in step 408 that the stop has been selected as the operation mode, the microcomputer 45 determines whether or not the previously transmitted step operation command signal is a stop command signal (step 409). If the step operation command signal has never been transmitted, the microcomputer 45 determines that the step operation command signal transmitted last time is not a stop command signal.

If the microcomputer 45 determines in step 409 that the previously transmitted step operation command signal is a stop command signal, the microcomputer 45 returns to step 401.
If the microcomputer 45 determines in step 409 that the previously transmitted step operation command signal is not a stop command signal, the microcomputer 45 transmits the stop command signal only once (step 410) and returns to step 401.

  To summarize the above, the microcomputer 45 indicates that each of the ascending operation command switch 35, the descending operation command switch 36, and the stop command switch 37 is pressed while the operation flag is ON, in other words, the communication confirmation switch 34 is pressed. When the operation is performed, it is determined that each of the ascending operation, the descending operation, and the stop is selected as the operation mode. Then, the microcomputer 45 transmits an ascending operation command signal, a descending operation command signal, and a stop command signal in accordance with each of the ascending operation, the descending operation, and the stop selected as the operation mode. As described above, the microcomputer 45 invalidates the operation mode selection operation of the step 16 by the ascending operation command switch 35, the descending operation command switch 36, and the stop command switch 37 unless the communication confirmation switch 34 is pressed. It is said. If the microcomputer 45 determines that any one of the ascending operation, the descending operation, and the stop is continuously selected as the operation mode, the ascending operation command signal, the descending operation command signal, and the Control is performed so that the stop command signal is not transmitted.

Next, transmission control of the communication confirmation signal and the normal operation signal by the microcomputer 67 of the communication control device 60 will be described with reference to FIG.
In FIG. 10, steps 501 to 504 are denoted as S501 to S504 for convenience of explanation.

In step 501, the microcomputer 67 determines whether or not a communication confirmation signal has been received from the remote controller 30.
If it is determined in step 501 that the microcomputer 67 has not received the communication confirmation signal, step 501 is repeated.
If the microcomputer 67 determines in step 501 that the communication confirmation signal has been received, a communication acceptance signal for notifying the remote controller 30 that it can communicate with the communication control device 60 is sent from the second wireless communication module 65. It is transmitted only once (step 502).

In step 503, the microcomputer 67 determines whether a safety switch operation signal is received from the escalator control panel 25.
If the microcomputer 67 determines in step 503 that the safety switch operation signal has been received, the process returns to step 501.
If the microcomputer 67 determines in step 503 that the safety switch operation signal has not been received, the second wireless communication module 65 sends a normal operation signal for notifying the microcomputer 45 of the remote controller 30 that the safety switch is not operating. Is transmitted only once (step 504), and the process returns to step 501.

Next, switching control of the step operation control signal by the microcomputer 67 of the communication control device 60 will be described with reference to FIG.
In FIG. 11, steps 601 to 606 are denoted as S601 to S606 for convenience of explanation.
In the initial state, the second wireless communication module 65 has not received the step operation command signal, and the microcomputer 67 controls the relay driver 72 to cut off the energization of the relay coils 69a to 69c. That is, all the step operation control signals are Low.

In step 601, the microcomputer 67 determines whether or not an ascending operation command signal has been received from the remote controller 30.
If it is determined in step 601 that the microcomputer 67 has not received the ascending operation command signal, the microcomputer 67 proceeds to step 603.
If it is determined in step 601 that the microcomputer 67 has received the ascending operation command signal, the microcomputer 67 controls the relay driver 72 to switch the ascending operation control signal to High only once (step 602), and returns to step 601.

In step 603, the microcomputer 67 determines whether or not a descending operation command signal has been received from the remote controller 30.
If the microcomputer 67 determines in step 603 that the descending operation command signal has not been received, the process proceeds to step 605.
In step 603, when the microcomputer 67 determines that the descending operation command signal has been received, the microcomputer 67 controls the relay driver 72 to switch the descending operation control signal to High only once (step 604), and returns to step 601.

In step 605, the microcomputer 67 determines whether a stop command signal has been received from the remote controller 30.
If the microcomputer 67 determines in step 605 that it has not received a stop command signal, it returns to step 601.
In step 605, when the microcomputer 67 determines that the stop command signal has been received, the microcomputer 67 controls the relay driver 72 to switch the stop control signal to High only once (step 606), and returns to step 601.

  In summary, when the microcomputer 67 of the communication control means 66 receives the ascending operation command signal, the descending operation command signal, and the stop command signal from the remote controller 30, the ascending operation control signal, the descending operation control signal, and The relay driver 72 is controlled so that each of the stop control signals (outputs of the normally open contacts 70a to 70c) is switched to High only once. In other words, the microcomputer 67 controls the relay driver 72 so that a step operation control signal corresponding to the step operation command signal from the remote controller 30 is output.

Next, operation control of the step 16 by the microcomputer 27 of the escalator control panel 25 will be described with reference to FIG.
In FIG. 12, steps 701 to 706 are denoted as S701 to S706 for convenience of explanation.
In the initial state, it is assumed that none of the step operation control signals has been switched between High and Low.

In step 701, the microcomputer 27 determines whether or not the ascending operation control signal has become High.
If the microcomputer 27 determines in step 701 that the rising operation control signal is not high, the microcomputer 27 proceeds to step 703.
If the microcomputer 27 determines in step 701 that the ascending operation control signal has become high, the microcomputer 27 controls the drive motor 5 to ascend the step 16 (step 702), and returns to step 701.

In step 703, the microcomputer 27 determines whether or not the descending operation control signal becomes high.
If the microcomputer 27 determines in step 703 that the descending operation control signal is not high, the microcomputer 27 proceeds to step 705.
If the microcomputer 27 determines in step 703 that the descending operation control signal has become high, the microcomputer 27 controls the drive motor 5 to cause the step 16 to descend (step 704), and returns to step 701.

In step 705, the microcomputer 27 determines whether or not the stop control signal becomes High.
If the microcomputer 27 determines in step 705 that the stop control signal is not high, the microcomputer 27 returns to step 701.
When the microcomputer 27 determines in step 705 that the stop control signal has become high, the microcomputer 27 stops driving the driving motor 5 to stop the travel of the step 16 (step 706), and returns to step 701.

  To summarize the above, the microcomputer 27 is used for driving so that the step 16 is raised, lowered, and stopped when the rising operation control signal, the descending operation control stop output, and the stop control signal are once switched to High. The drive of the electric motor 5 is controlled. That is, since the step operation control signal including the ascending operation control signal, the descending operation control stop output, and the stop control signal is based on the step operation command signal, the microcomputer 27 receives the step operation control signal from the communication control means 66. The driving motor 5 is controlled to operate the step 16 in the operation mode selected by the switch group 33 based on the above.

Next, in the escalator 1 configured as described above, an operation when the manager uses the remote controller 30 to raise, lower, or stop the step 16 will be described.
First, a case where the step 16 is driven up or down from the state where the running of the step 16 is stopped can be described.

  The administrator approaches one of the communication control devices 60 arranged on the upper and lower floors, presses the communication confirmation switch 34 of the remote controller 30 to transmit a communication confirmation signal, and receives a communication acceptance signal from the communication control device 60. Make sure you do. That is, it is confirmed that the first LED 41 emits light. If the first LED 41 does not emit light, the administrator approaches the communication control device 60 until the first LED 41 emits light while pressing the communication confirmation switch 34. Here, when the distance between the first wireless communication module 38 of the remote control 30 and the second wireless communication module 65 of the communication control device 60 is within 1 m, the remote control 30 and the communication control device 60 can communicate. The first LED 41 emits light. Note that when the second LED 42 is not emitting light, one of the safety switches of the escalator 1 is operating, so the administrator stops the operation of the remote controller 30 and takes measures according to the operated safety switch.

Next, the administrator presses the ascending operation command switch 35 when the operator wants to raise the step 16 while pressing the communication confirmation switch 34 of the remote controller 30, and presses the descending operation command switch 36 when the operator wants to descend. The operation mode of the step 16 is selected.
Thereby, the ascending operation command signal or the descending operation command signal is transmitted from the remote controller 30, and the transmitted signal is received by the communication control device 60.

  At this time, if the microcomputer 67 of the communication control device 60 determines that the ascending operation command signal has been received, the microcomputer 67 transmits a code for switching the ascending operation control signal to High only once to the relay driver 72. If the microcomputer 67 determines that the descending operation command signal has been received, the microcomputer 67 transmits a code for switching the descending operation control signal to High only once to the relay driver 72.

When the microcomputer 27 of the escalator control panel 25 determines that the ascending operation command output has been switched to High, the microcomputer 27 controls the drive motor 5 to cause the step 16 to perform ascending operation, and determines that the descending operation command output has been switched to High. The drive motor 5 is controlled so that the step 16 is lowered.
As a result, the step 16 travels in the operation mode selected by the switch group 33 of the remote controller 30.

Next, a case where the step 16 that is in the ascending operation or the descending operation is stopped will be described.
Further, when the manager stops traveling of the step 16, he approaches one of the communication control devices 60, presses the communication confirmation switch 34 of the remote controller 30, transmits a communication confirmation signal, and accepts communication from the communication control device 60. Confirm that the signal is received. That is, it is confirmed that the first LED 41 emits light. When the first LED 41 does not emit light, the administrator determines that the remote controller 30 is out of the communication range with the communication control device 60 and keeps pressing the communication confirmation switch 34 until the first LED 41 emits light. Get closer.
Next, the administrator presses the stop command switch 37 while pressing the communication confirmation switch 34 of the remote controller 30, and selects stop as the operation mode of the step 16.
As a result, a stop command signal is transmitted from the remote controller 30, and the stop command signal is received by the communication control device 60.

When the microcomputer 67 of the communication control device 60 determines that it has received the stop command signal, it transmits a code for switching the stop control signal to High only once to the relay driver 72, so the microcomputer 27 of the escalator control panel 25 outputs the stop command signal. Is switched to High, the drive motor 5 is stopped, and the travel of the step 16 is stopped.
As described above, the operation of the step 16 is stopped according to the operation mode (stop) selected by the switch group 33 of the remote controller 30.

As described above, the administrator can control the operation of the step 16 according to the operation mode of the step 16 selected by the switch group 33 of the remote controller 30.
If the communication confirmation switch 34 is not pressed, the operations of the ascending operation command switch 35, the descending operation command switch 36, and the stop command switch 37 are configured to be invalid. Only the ascending operation command switch 35 and the descending operation command switch 36 can be prevented from malfunctioning when the step 16 is operated unintentionally.

  Even if the key switch 80 is used, the step operation control signal input to the escalator control panel 25 can be switched, so that the operation of the step 16 can be controlled. Normally, the operation of the step 16 is controlled by the remote controller 30, but the key switch 80 is provided so that the operation of the step 16 can be controlled even in an emergency such as when the remote control 30 is damaged.

  The passenger conveyor 1 of the present invention is configured such that the remote controller 30 can select the operation mode of the step 16 and wirelessly transmit a step operation command signal corresponding to the selected operation mode. The communication control device 60 is configured to be communicable with the remote controller 30 and configured to output a step operation control signal corresponding to the step operation command signal received from the remote controller 30 to the escalator control panel 25. Further, the escalator control panel 25 is configured to control the drive motor 5 so as to operate the step in the operation mode of the step selected by the remote controller 30 based on the step operation control signal.

  Therefore, since the operation of the step 16 can be controlled by the remote controller 30, the administrator can control the operation of the step 16 with an easy posture without taking a tight posture.

  The wireless communication between the remote controller 30 (first wireless communication module 38) and the communication control device 60 (second wireless communication module 65) is performed when the distance between them is within a range of, for example, 1 m. It is configured to be able to do. Therefore, even in a building in which a plurality of escalators are arranged adjacent to each other, only the communication control device 60 of the escalator 1 that wants to control the travel of the step 16 is made to receive the step operation command signal from the remote controller 30 and Sixteen runs can be controlled.

  In addition, although the passenger conveyor was demonstrated as what is the escalator 1, this invention is applicable also to the moving walk as a passenger conveyor.

The communication control means 66 of the communication control device 60 includes a microcomputer 67 and an operation control circuit 68, and the microcomputer 67 relays the operation control circuit 68 based on the step operation control signal received by the second wireless communication module 65. It demonstrated as what controls the output of the step operation control signal to the escalator control panel 25 by controlling the driver 72.
However, the communication control unit 66 omits the operation control circuit 68 and is configured to be able to perform wireless communication between the communication control unit 66 and the escalator control panel 25. Furthermore, the microcomputer 67 of the communication control unit 66 is connected to the step. Depending on the operation control signal, a step operation control signal to the escalator control panel 25 may be output wirelessly.
