Passenger transportation device and control method thereof

The invention relates to a passenger transportation device and a control method thereof, and the task aims at a phenomenon generated through ongoing change of moving handrail in early time. The passenger transportation device comprises multiple steps, a driving device, a moving handrail, a baluster a cover plate for forming an inlet port of the moving handrail and a control portion, the device also comprises: a protection body which is arranged near the inlet port in a way of displacing in a moving direction of the moving handrail and avoids the invasion of foreign matters to the inlet port, and a sensor which is used for detecting the contact between the protection portion and the moving handrail, in a condition that an output value from the sensor sustains the output value from the sensor in the first time exceeding a first threshold value and is less than a second threshold value which is more than the first threshold value, that is a specific state, the control portion outputs specific information in a st
