An elevator brake wear detection method, an elevator brake wear detection device and an elevator brake. The elevator brake includes a fixed part with an electromagnetic member and a moving part with a friction member; in a first state, the elevator brake drives the moving part to move toward an elevator power device and contact the elevator power device through the friction member to provide a braking force to stop an elevator car, and in a second state, the elevator brake provides an electromagnetic force through the electromagnetic member to disengage the friction member from the contact with the elevator power device.

An elevator brake performance detection method includes controlling an input voltage or current of the electromagnetic member so that the elevator brake enters the braking state, and recording a corresponding current data trajectory of the electromagnetic member based on time characteristic; determining a first target point and a second target point in the current data trajectory according to the current data trajectory, the first target point and the second target point being a first peak point in the current data trajectory, and a start point at which the current value changes from decreasing to increasing in the current data trajectory, respectively; and calculating a time difference between the first target point and the second target point as a braking time of the elevator brake.

An elevator system includes at least one autonomous unit for controlling an elevator and a multichannel-edge-gateway that builds communication between the autonomous unit and data resources on an IoT network. The multichannel-edge-gateway has more than one communication channel), wherein these communication channels provide data communicating using the same protocol or different protocols either synchronously or asynchronously. The multichannel-edge-gateway includes a channel assignment that automatically matches one of the communication channels to one of the protocols according to data to be sent from the multichannel-edge-gateway.

A method and an apparatus for computing allocation decisions in an elevator system is provided. Historical passenger batch journey data relating to the elevator system is obtained, wherein each passenger batch journey includes an origin and a destination floor of the journey, the number of passengers of the journey and the time of the journey. Historical passenger traffic statistics are constructed based on the passenger batch journey data, and expected calls are modelled based on the passenger traffic statistics. The modelled expected call is taken into account in computing subsequent allocation decisions in the elevator system.

An electronic safety actuator (1) for an elevator safety brake, includes a first solenoid (2), a magnet (3), movable by the first solenoid (2) between a first position proximate to the first solenoid (2) and a second position distal from the first solenoid (2) a second solenoid (6) and a detector (8). The detector (8) is arranged to apply an electrical signal to one of the first solenoid (2) and the second solenoid (6), and to detect an electrical signal induced in the other of the first solenoid (2) and the second solenoid (6) as a result of the applied electrical signal.

This disclosure relates to a system and method configured to identify and, if necessary, respond to conditions indicative of electromagnetic brake temperature, and in particular relates to passenger conveyers, such as elevators, employing the system and method. More specifically, an example passenger conveyer system includes an electromagnetic brake and a controller configured to identify a condition indicative of a temperature of the electromagnetic brake approaching a boundary of a predetermined operating range.

An elevator system includes a component adapted to perform a function, a sensor, and a control configuration. The sensor is configured to detect an operating parameter associated with the function. The control configuration is configured to receive a parameter signal from the sensor, and extract a predesignated feature from data associated with the parameter signal. The predesignated feature is then aggregated by the control configuration and machine learning is applied to determine a degradation level of the function associated with the predesignated feature.
