Recently, two-speed passenger conveyors, which operate at four-thirds the speed (40 m/min) compared to normal (30 m/min), have been rapidly increasing in order to increase passenger transport capacity during morning and evening rush hours on subways, etc. There is. As the user base becomes more diverse, unaccustomed people such as elderly people with weak legs and young children may unknowingly get on a two-speed passenger conveyor while it is running at high speed. In that case,
If you are unable to keep up with the moving speed of the steps and fall, especially if you are descending at high speed, there is a risk that you may fall to the floor below. In order to prevent this accident, guides are sometimes placed at the entrance and exit during high-speed driving, but this also raises the problem of increased personnel costs. Also,
Even if the switch can only be turned on to the high-speed operation side during upward operation, a human operator must confirm the status of all switches before starting the conveyor. In that case, the vehicle may start descending operation without realizing that the switch has been switched to high-speed operation, and it cannot be said that accidents can be completely prevented.

れる危険が生じない。 When the speed changeover switch 10 is set to the high speed side (H side), the driving direction selection switch 1
Consider the case where 5 is put into the descending operation side (D side). In this case, the normally closed contact 11b remains closed and the descending operation relay 12 is energized, and the normally open contact 11b remains closed.
a3 is closed and a self-holding circuit of the descending operation relay 12 is formed. However, the speed changeover switch 10
In the circuit for exciting the high-speed operation relay 13 selected by , although the normally open contact 12a 1 is closed, the normally closed contact 12b 1 of the descending operation relay 12
is opened and the high-speed operation relay 13 prevents excitation. In addition, the normally open contact 12 of the descending operation relay 12
The low-speed operation relay 14 is forcibly energized by the closure of a2 , and the passenger conveyor is operated downward at low speed. That is, even if the driving direction selection switch 15 is turned to the downward driving side even though the speed changeover switch 10 is turned to the high speed side,
The relay 13 for high-speed operation is not energized, and the passenger conveyor is operated downward at low speed, so that there is no danger of downward operation at high speed.

Furthermore, FIG. 2 shows another embodiment according to the present invention. This embodiment uses the normally open contact 12 shown in FIG.
a 2 is removed. In this embodiment, even if the speed changeover switch 10 is set to the high speed side, if the driving direction selection switch 15 is set to the upward driving side, the 2-speed man conveyor can move up at high speed, but it will not change to the downward driving side. Normally closed contact 1 when turned on
2b1 is opened and upward operation is blocked, and the man conveyor is not started.

Even if the speed changeover switch 10 is set to the high speed side, depending on the operating direction of the two-speed man conveyor,
Low-speed operation is performed in the downward direction, and high-speed operation is performed in the upward direction. If the speed changeover switch 10 is set to the high speed side and the vehicle is in the descending mode, the passenger conveyor may not be activated. Therefore, the danger of causing the passenger conveyor to descend at high speed due to human error can be eliminated.
