Passenger-transporting system with device for determining operating state

Abstract

A device (2) serves for determining the operating state, in particular for measuring the speed, of a passenger-transporting system (1) designed in the form of a lift, escalator or moving walkway. An arrangement (30) made up of auxiliary elements (31-34) is provided here. Also provided is a sensing device (37). The arrangement (30) made up of the auxiliary elements (31-34) rotates, in a manner corresponding to a movement of at least one transporting element (5) of the passenger-transporting system (1), about an axis of rotation (35). The arrangement (30) made up of the auxiliary elements (31-34) is configured, and the sensing device (37) is assigned to the auxiliary elements (31-34), such that the sensing device (37) can sense whether an auxiliary element (31-34) is, or is not, located at acertain sensing location (38). The auxiliary elements (31-34) are configured here in a manner corresponding to a first configuration type (41) and a second configuration type (42). During rotation ofthe arrangement (30) made up of the auxiliary elements (31-34), the sensing device (37) can sense whether an auxiliary element (31-34) which is located at a certain sensing location (38) is of the first configuration type (41) or of the second configuration type (42). Furthermore, during rotation of the arrangement (30) made up of the auxiliary elements (31-34), the sensing device (37) can assignan auxiliary element (31) of the first configuration type (41) and an auxiliary element (32) of the second configuration type (42) to one another such that the direction of rotation (3A, 4A) of the arrangement (30) can be determined from the order in which the auxiliary element (31) of the first configuration type (41) and the auxiliary element (32) of the second configuration type (42) are sensed. The invention also specifies a passenger-transporting system (1) with such a device (2) as well as a method which can be implemented by such a device (2).

Description

technical field [0001] The invention relates to a people transport system with a device for determining an operating state, which is designed as an elevator, an escalator or a moving walkway, and to a method for determining an operating state, in particular for measuring a speed , this method is used for people moving equipment designed as lifts, escalators or moving walkways. Background technique [0002] In EP 1 541 519 B1 a people carrier is known which has a radar sensor in order to detect approaching users. In order to transport people, the speed is increased here from the reduced value to the normal speed. In order to control the drive correctly, the speed of the step belt or pallet belt must be detected. [0003] For determining the speed, it is conceivable to use a drive motor with an integrated encoder. Such a drive motor has the disadvantage that an additional special design of its construction is required due to the additional encoder, which entails high produc...

Problems solved by technology

The disadvantage of this type of drive motor is that it is additionally designed specifically for its construction concept on the basis of an additional encoder, which results in high production costs.
