The present disclosure for raising an alert in connection with the use of a platform lift, in particular a stairlift, the lift having a rail, a drive unit having a platform, a chair (8), for driving along the rail, at least one control unit arranged at the drive unit.

The method including determining the way of usage of the platform lift, comparing the way of usage with an alert definition, determining whether the way of usage confirms with the alert definition, generating an alert, if the way of usage conforms to the alert definition and providing the alert to a user.

The measurement arrangement for measuring the rotation speed of a component of an elevator, escalator, moving walkway or moving ramp comprises an inductive sensor that is arranged stationary in respect of a rotation axis of the component and adjacent to the component or a measurement part that is attached to the component in a rotationally fixed manner, and the component or the measurement part is configured as rotationally unsymmetrical about the rotation axis so that different angular positions of the component about the rotation axis generate different output signals in the inductive sensor.

A passenger transport system has a device for registering users in a pass-through zone and the device includes at least two sensors, which sensors operate in accordance with the time-of-flight measurement principle, and a signal evaluation unit. Each sensor includes an emitter emitting electromagnetic waves into a detection area and a receiver, arranged adjacent to the emitter, that acquires the electromagnetic waves that were emitted by the emitter and reflected from the detection area, wherein the emitter and the receiver of each sensor are directed into the pass-through zone. At least one sensor of the device is respectively arranged on opposing sides of the pass-through zone and the principal direction axes of the detection areas of the sensors are arranged parallel to one another and orthogonal to the longitudinal extent of the pass-through zone.

A drive belt monitoring system for a passenger conveyor (10) is provided having a drive belt (30) having at least one cord (36) extending longitudinally within the drive belt (30). The monitoring system (50) includes: a first sensor (52) configured to measure the pretension of the drive belt (30); a second sensor (54) configured to determine a passenger load on the drive belt (30); a third sensor (56) configured to determine the resonance frequency of the drive belt (30); and a controller (60) configured to evaluate a condition of the drive belt (30) based on: the measured pretension of the drive belt (30), the determined passenger load of the drive belt (30), and the determined resonance frequency of the drive belt (30).

A device and a method for controlling an apparatus being an elevator, an escalator or automatic doors are provided, by which it is detected whether a fault is present in the apparatus. It is determined, when the fault is present, whether an automatic fault clearing may be carried out, and if it is determined that the automatic fault clearing may be carried out, the automatic fault clearing is performed by automatically clearing one or more faults.

The present invention discloses an escalator monitoring system, which includes a data collection device disposed near the parts of the escalator that require monitoring in order to collect data the parts relevant to the operation of the escalator, a data transmittal device used to send the collected data, a cloud processor used to receive the data, to compare the data against threshold data of the parts obtained under normal operating conditions stored in the database of the cloud processor, and to respond based on the comparison result. The present invention can collect the data and analyze it in any environment independent of subjective human judgment, predict possible failure without the need to stop the operation of the escalator, save maintenance time, reduce associated cost, and thus improve its safety and ride comfort.

The present invention relates to a method for initiating a data connection between a central server and a control unit communicatively coupled to an elevator, escalator or autowalk. The method comprises: receiving a trigger signal from the central server, wherein the trigger signal is delivered with a service of a mobile communication network into which the control unit is communicatively coupled to; detecting if the trigger signal complies with at least one pre-defined requirement; and in response to a positive outcome of the detection initiating a data connection establishment from the control unit to the central server. The invention also relates to a control unit for an elevator, escalator or autowalk.
