Abstract:
A method and an elevator controller (31) for detecting a malfunction such as elevator blockage in an observed elevator (3) is proposed. The method comprises: acquiring first data during an application phase, the first data correlating with at least one condition in the observed elevator (3); acquiring further data during the application phase, the further data correlating with the at least one condition in other elevators (5); determining a current relative behaviour of the observed elevator during the application phase based on a comparison of the first data with the further data; and detecting the malfunction in the observed elevator (3) based on an analysis of the current relative behaviour. Preferably, an information about a normal relative behaviour of the observed elevator (3) as learned in a machine learning procedure during a preceding learning phase may be taken into account upon analysing the current relative behaviour of the observed elevator (3). The proposed method may enable automatically detecting malfunctions in an elevator while reducing a probability of false alarms.
Abstract:
An elevator (1) comprising a displaceable elevator car (3) is proposed, wherein a holder structure (17) is fixed to the elevator car (3) and is configured to hold a passenger's smart mobile device (19), the mobile device (19) including at least one sensor (20), and the holder structure (17) being specifically configured to mechanically couple the mobile device (19) to the elevator car (3) in a releasable manner. Furthermore, a method for monitoring an operation of an elevator (1) is proposed, the method comprising providing a passenger's smart mobile device (19) including a plurality of sensors (20) with a specific application software, the application software controlling the smart mobile device (19) to execute the following monitoring procedure: - repeatedly supervising measurement values of at least one of the sensors (20) of the mobile device (19); - upon occurring of a specific parameter pattern in the measurement values, starting of a measurement acquisition procedure during which measurement values are sensed by at least one of the sensors (20) and the sensed measurement values are transmitted to an evaluation unit (37) for further evaluation. Therein, the specific parameter pattern specifically results upon the mobile device (19) being held in at least one of a predefined position and a predefined orientation in the elevator car (3).
Abstract:
A method and a device for monitoring an operation status of an elevator (1) are proposed. Therein, the elevator (1) comprises a first sensor (23), such as e.g. an RGB sensor (25), an IR sensor (27) or a load sensor (29), being configured for obtaining first sensor data enabling deriving information about a presence of a passenger within a first sensing area of the first sensor (23), and a second sensor (13), such as e.g. a camera (15) or a microphone (17), being configured for obtaining second sensor data from within a second sensing area, the second sensor data enabling deriving information about the operation status of the elevator (1). The method comprises determining whether a passenger is present within the first sensing area of the first sensor (23) and triggering a monitoring procedure only in case no passenger is present within the first sensing area of the first sensor (23). Therein, the monitoring procedure comprises obtaining second sensor data from the second sensor (13) and deriving information about the operation status of the elevator (1) by processing the obtained second sensor data. The method steps may be executed by a data processor 31 of the monitoring device 3. With the proposed approach, privacy concerns of passengers may be alleviated upon monitoring elevator components using e.g. a camera (15) or a microphone (17).
Abstract:
A method and a device (11, 21) for monitoring characteristics of a door motion procedure of an elevator door (7) using a smart mobile device (11) including multiple sensors (13) is proposed. The method comprises: (i) determining a time window (23) within which a door motion is assumed to occur, wherein a start time limit (25) and an end time limit (27) enclose a time interval (26) of the time window (23) and wherein at least one of the start time limit (25) and the end time limit (27) is determined based on first measurement values (37) acquired by a first sensor (29) comprised in the smart mobile device (11); and (ii) detecting the characteristics of the door motion procedure of the elevator door (7) based on second measurement values (39) acquired during the time window (23) by a second sensor (31) comprised in the smart mobile device (11). With the proposed two-step approach, door motion characteristics may be reliably monitored using e.g. a passenger's smart mobile phone while substantially limiting sensing and processing capacities to be provided by the smart mobile phone as well as avoiding compromising privacy requirements upon using the passenger's smart mobile phone.
Abstract:
A method for determining a mapping of a number of floors to be served by an elevator (1) is proposed. The method comprises the steps of: (a) determining, during a multiplicity of trips of an elevator cabin of the elevator, a trip-dependent physical parameter value which unambiguously depends on at least one of a trip duration (Δt) and a trip distance (Δs); and (b) clustering the determined trip-dependent physical parameter values to clusters (19) to define each of the number of floors in the mapping. The method allows, in a training phase, to automatically determine the number of floors served by an elevator and then, in an operation phase, classify each of the observed trips and finally detect and track a current position of the elevator cabin. An elevator monitoring device implementing such method may be retrofitted into existing elevators for e.g. remotely monitoring the elevator operation and does not necessarily require any data transfer between components of the elevator and the elevator monitoring device.

Abstract:
A method for monitoring an operation of an elevator door arrangement (1) are described, the elevator door arrangement (1) comprising at least one door wing (3) and an electric actuator (5) for displacing the door wing (3) in at least one of an opening and a closing direction (17) of during a door motion event. The method comprising a learning phase and an application phase. Therein, during the learning phase, different types of door motion events are identified and for each type of door motion event a reference motion event duration is determined. During the application phase, a door arrangement operation is observed such as to detect door motion events and the different types of door motion events are distinguished upon comparison of the reference motion event durations with actual motion event durations as measured during the application phase. Using the proposed method, door motion events in an elevator(100)may be recognized and monitored in an automatic manner.
