At this time, each driving handle 40 moves in the same direction and speed as the traveling direction and speed of the escalator 10. Here, although the escalator 10 in the upward direction is shown and described in FIG. 2, the same configuration and function are applied to the escalator in the downward direction.

The boarding detection sensor 102 detects whether or not an occupant boards the escalator 10. At this time, the boarding detection sensor 102 may be implemented as a weight detection sensor, and may determine boarding of the escalator 10 by sensing the weight of the occupant moving from the elevator plate 20 to the escalator 10. Alternatively, the boarding detection sensor 102 may be implemented as a motion detection sensor, and may determine boarding of the escalator 10 by detecting a passenger moving from the elevator plate 20 to the escalator 10. However, the boarding detection sensor 102 is not limited to the type of sensor described, and any sensor may be used as long as it is a sensor capable of determining whether to board the escalator 10.

The plurality of touch sensors 104 are installed at set intervals on each of the left driving handle 40 and the right driving handle 40 of the escalator 10. In this case, it is preferable that the plurality of touch sensors 104 are installed at intervals corresponding to the intervals between the steps of the escalator 10. In addition, each touch sensor 104 has a unique identification number that is different from each other, and may transmit a corresponding identification number and a detection signal according to whether the occupant touches the driving handle 40.

The detection signal receiver 106 receives a detection signal from each of the touch sensors 104. At this time, it is preferable that the detection signal receiving unit 106 receives a unique identification number corresponding to each touch sensor 104 together with the detection signal.

When detecting that a new passenger is boarding the escalator 10 by the boarding detection sensor 102, the detection signal determination unit 108 determines whether a new detection signal is received by the detection signal receiving unit 106 within a set time. Judge That is, when it is determined that the new occupant has moved from the elevator plate 20 to the escalator 10 and boarded the escalator 10, the detection signal determination unit 108 is determined by the detection signal receiving unit 106 within a set time therefrom. It is possible to determine whether a new detection signal is received, and to identify whether a new occupant has touched the driving handle 40 of the escalator 10. At this time, the detection signal determination unit 108 recognizes the identification number of the touch sensor 104 located within a set range among the plurality of touch sensors 104 moving in the same direction and speed as the escalator 10, and recognizes the recognized touch. It may be determined whether a new detection signal is received from the sensor 104.

The number of passengers counter 110 counts the number of passengers on the left and the number of passengers on the right of the escalator 10 based on the detection signal received by the detection signal receiver 106. At this time, the number of passengers counter 110 sets the start point and the end point of the number of passengers counter, as shown in FIG. 3 for the left and right driving handles 40, and between the start point and the end point. The number of left occupants and the number of right occupants may be counted, respectively, based on a detection signal received from the located touch sensor 104. In this case, the number of passengers counter 110 may receive a detection signal from a point in time when each of the touch sensors 104 passes the starting point with respect to the rotation direction of each of the left and right driving handles 40, and , It may be implemented so that the reception of the detection signal is blocked from the point when the end point is elapsed.

The driving limiting unit 112 determines that a new detection signal has not been received by the detection signal determination unit 108 or the difference between the number of left occupants and the number of right occupants counted by the occupant counter unit 110 is a set value. In the above case, the driving of the escalator 10 is limited. That is, the driving limiting unit 112 detects that a new passenger is boarding the escalator 10 by the boarding detection sensor 102, but the new detection signal has not been received by the detection signal receiving unit 106 within a set time therefrom. When it is determined, it is determined that the new occupant does not hold the driving handle 40 of the escalator 10 after boarding, and accordingly, the driving of the escalator 10 may be restricted. In addition, when the difference between the number of passengers on the left and the number of passengers on the right counted by the number of passengers counter 110 is greater than or equal to a set value, It is determined that the boarding is biased to one side, and accordingly, the driving of the escalator 10 can be limited. In this case, the driving limiting unit 112 may gradually decrease the driving speed of the escalator 10. In this case, it is preferable that the driving limiting unit 112 decreases by setting a reduction ratio of the driving speed so that the occupant on board is not impacted by the inertial force. In addition, when the detection signal is not received from any one of the plurality of touch sensors 104, the driving limiting unit 112 may determine that there is no occupant of the escalator 10 and stop the driving of the escalator 10. have.

When it is determined that a new sensing signal has not been received by the sensing signal determination unit 108, the touch requesting unit 114 may request a new occupant to hold the driving handle 40. That is, the touch request unit 114 detects that a new passenger is boarding the escalator 10 by the boarding detection sensor 102, but the new detection signal has not been received by the detection signal receiving unit 106 within a set time therefrom. If it is determined, a new passenger may be requested to hold the driving handle 40 of the escalator 10. At this time, the touch request unit 114 is installed as a display on the ceiling in front of the escalator 10 in the traveling direction to display a request signal for a touch of the driving handle 40 as a text, or may be implemented as a speaker and output as a voice. have.

When the difference between the number of left occupants and the number of right occupants counted by the occupant counter unit 110 is greater than or equal to a set value, the movement request unit 116 is at least one occupant on the side with the smaller number of occupants on the left and the right. You can ask to move to the other side. That is, when the difference between the number of passengers on the left and the number of passengers on the right counted by the number of passengers counter 110 is greater than or equal to a set value, It is determined that the boarding is biased to one side, and accordingly, it is possible to request at least one occupant of the side with a small number of occupants to move to the other side. In this case, it is preferable that the movement request unit 116 requests to move from the most recently boarded occupant. In addition, the movement request unit 116 may request movement by text or voice through a display or speaker installed in front of the escalator 10 in the moving direction.

The LED unit 118 is installed corresponding to each touch sensor 104. At this time, the LED unit 118 is installed on the upper surface of each touch sensor 104, it may be implemented to be turned on when the occupant touches the touch sensor 104. For example, when a passenger touches the touch sensor 104 after boarding the escalator 10, the LED unit 118 may be lit in blue or green.

The color changing unit 120 receives the detection signal at the start point of the escalator 10 and then stops receiving the detection signal before the end point of the escalator 10, the touch sensor 104 corresponding to the detection signal. ) To change the color of the LED unit 118. For example, when the occupant boards the escalator 10 and passes the starting point, holding the driving handle 40 but placing the driving handle 40 before passing the end point, the color change unit 120 As shown in FIG. 4, a touch sensor corresponding to the occupant who releases the hand of the driving handle 40 so as to be distinguished from the existing lighted LED unit 118-2 and the existing lighted LED unit 118-4. The LED part 118-6 of 104 can be displayed by changing its color to red. In this case, the touch request unit 114 may request a passenger corresponding to the LED unit 118-6 whose color is changed by the color change unit 120 to continuously touch the driving handle 40.

In this case, the driving limiting unit 112, as shown in FIG. 5, is based on the detection signal received from each turn-point sensor 104 between the start point and the end point of the escalator 10, the left and right occupants Since the number is calculated and the driving of the escalator 10 is limited accordingly, if the occupant releases the driving handle during the moving process after boarding the escalator 10, the driving of the escalator 10 may be limited accordingly. At this time, the occupant corresponding to the position recognizes that the driving limitation of the escalator 10 by the driving limiting unit 112 is due to his or her fault because the LED unit 118-6 corresponding to his position is changed to a different color. It can be done, and accordingly, the drive handle 40 of the escalator 10 is held again.
