Abstract
A people conveyor (2), which is configured for conveying passengers by at least one conveyance band (8) travelling along a closed loop, comprises at least one handrail element (6) which is configured for moving parallel to the at least one conveyance band (8) along a travel path forming a closed loop; and at least one force sensor (18a, 18b), which is configured for detecting a force (FS1, FS2) exerted by the at least one handrail element (6) in a direction transverse to the direction of movement of the at least one handrail element (6) and for providing a corresponding force signal.
Claims18
People conveyor configured for conveying passengers by at least one conveyance band travelling along a closed loop and comprising:
- at least one handrail element which is configured for moving parallel to the at least one conveyance band along a travel path forming a closed loop;
- and
- at least one force sensor, which is configured for detecting a force (FS1, FS2) exerted by the at least one handrail element in a direction transverse to a direction of movement of the at least one handrail element and for providing a corresponding force signal;
- wherein the at least one handrail element is at least partly guided by a guide rail and wherein the at least one force sensor is configured for detecting a force (FS1, FS2) which is exerted by the at least one handrail element onto the guide rail.
People conveyor configured for conveying passengers by at least one conveyance band travelling along a closed loop and comprising:
- at least one handrail element which is configured for moving parallel to the at least one conveyance band along a travel path forming a closed loop;
- and
- at least two force sensors, which are configured for detecting a force (FS1, FS2) exerted by the at least one handrail element in a direction transverse to a direction of movement of the at least one handrail element and for providing a corresponding force signal;
- at least one handrail drive, which is configured for driving the at least one handrail element;
- wherein, in the direction of movement of the handrail element, a first force sensor of the at least two force sensors is provided on one side of the handrail drive, and a second force sensor of the at least two force sensors is arranged on the other side of the handrail drive.
People conveyor configured for conveying passengers by at least one conveyance band travelling along a closed loop and comprising:
- at least one handrail element which is configured for moving parallel to the at least one conveyance band along a travel path forming a closed loop;
- at least one force sensor, which is configured for detecting a force (FS1, FS2) exerted by the at least one handrail element in a direction transverse to a direction of movement of the at least one handrail element and for providing a corresponding force signal;
- a handrail element power calculation unit, which is configured for calculating a driving power (Pup, Pdown) which is necessary for driving the at least one handrail element based on at least one force signal provided by the at least one force sensor.
Method of determining the power which is necessary for driving at least one handrail element of a people conveyor, wherein the method includes:
- driving the at least one handrail element;
- detecting a force (FS1, FS2) which is exerted by the at least one handrail element in a direction oriented in a direction transverse to the direction of movement of the at least one handrail element;
- and
- calculating the driving power (Pup, Pdown) which is necessary for driving the at least one handrail element from the detected force (FS1, FS2).
