Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor control system.

[0002]

2. Description of the Related Art As a conventional passenger conveyor control system, a moving speed of a moving tread surface is switched at a preset timer time, or a push button for switching a control circuit is provided and operated. Thus, the moving speed of the moving tread surface is switched.

[0003]

However, in the conventional passenger conveyor control system, in the former case in which the moving speed of the moving tread surface is controlled by the timer, the moving speed by the current driving is not known and the passengers such as the elderly cannot be recognized. In the latter case, which cannot be used efficiently, and in which the push button is operated to control the moving speed of the moving tread, in the latter case, if there is a passenger such as an elderly person, if the operation of the push button for switching the control circuit is forgotten, the moving tread The traveling speed cannot be reduced, and a dangerous situation may occur such as falling on the moving tread while maintaining the normal traveling speed.In both cases, the elderly and other passengers can travel efficiently and safely. The passenger conveyor could not be used.

[0004] It is an object of the present invention to provide a passenger conveyor control system that enables even elderly passengers to use the vehicle efficiently and safely.

[0005]

In order to achieve the above object, the present invention has a moving tread surface for carrying a passenger from a passenger conveyer entrance to a predetermined place, and a moving speed of the moving tread surface. In a passenger conveyor control system configured to be able to be switched to at least two stages, a determining means for determining the walking speed of the passenger to the entrance of the passenger conveyor, and the determining means determined that the walking speed of the passenger is less than a predetermined speed. A speed reducing means for reducing the moving speed of the moving tread surface.

The control system for a passenger conveyor according to the present invention is provided with a judging means for detecting a walking speed of the passenger to the entrance of the passenger conveyor. When the judging means determines that the walking speed of the passenger is slower than a predetermined walking speed. Since the moving speed of the moving tread is reduced by the deceleration means, the passenger does not need any special operation, and the decelerated passenger conveyor can be efficiently and safely used by passengers such as the elderly.

Therefore, the normally open contact 11B of the second relay 11 is opened, the circuit of the timer 12 is disconnected from the control power supplies P and N, and the timer 12 stops operating. At this time, if the timer 12 stops operating earlier than the set time of the timer 12, the normally open contact 12A does not close and the deceleration command circuit 15 does not operate.
That is, when the timer 12 stops operating earlier than the set time of the timer 12, it is determined that the passenger passing between the first photoelectric detection device 5 and the second photoelectric detection device 4 is a healthy person who can move at a normal speed. Then, the passenger conveyor is not decelerated and the operation is continued at the normal speed.

On the other hand, when the passenger passes the second photoelectric detection device 4 and the set time has elapsed since the timer 12 started measuring, for example, when about 3 seconds have elapsed, the timer 12 Normally open contact 12A is closed and the control power supply P
... Normally open contact 12A Fourth relay 14 Deceleration command circuit 15 A circuit for control power supply N is formed. Therefore, the deceleration command circuit 15 is activated, and the moving speed of the moving tread surface 2 becomes 3
The switch is automatically switched from 0 m / min to 20 m / min, and the fourth relay 14 is energized to open its normally open contact 14A1.

Thereafter, when the passenger passes through the second photoelectric detection device 4 and the second switch 9 is opened, the second relay 11 is deenergized and its normally open contact 11B is closed, and the initial state of waiting for the next passenger is started. State.

As described above, the passenger conveyor control system includes the first photoelectric detection device 5 at the passenger conveyor entrance 1A,
A second photoelectric detecting device 4 is provided at a predetermined distance, and a determining means for determining a walking speed of a passenger traveling between the two photoelectric detecting devices 5 and 4 based on an operation of the two photoelectric detecting devices 5 and 4 is configured. When the speed is lower than the walking speed of the passenger conveyor, the speed reducing means for reducing the moving speed of the moving tread surface 2 of the passenger conveyor 1 is operated. 1 can be used safely. At a predetermined time before and after the deceleration means of the passenger conveyor 1 operates, the alerting device 16
Is activated so that the voice guidance broadcast is performed, so that the passengers know that the moving speed of the moving tread surface is controlled, and the passengers such as the elderly can use the passenger conveyor efficiently and safely.

In the above-described embodiment, it has been described that the operation is performed when the set time is reached when about 3 seconds have elapsed since the timer 12 started measurement. However, the present invention is not limited to about 3 seconds. Instead, the timer 12 may be configured so that the required time can be set. Further, the deceleration command circuit 15 may be activated after the alerting device 16 is activated.
