A method for verifying the brake force of an electromagnetic elevator brake includes the steps of closing the brake, supplying electrical current to the brake up to a preset verification level and determining whether there has been any movement of the elevator car being braked.

The invention relates to an elevator comprising an electric linear motor comprising at least one linear stator designed to be located in a fixed correlation to an environment, particularly building, and at least one mover designed for connection with an elevator car to be moved and co-acting with the stator to move the car, which motor comprises a stator beam supporting said at least one stator, which stator beam has at least one side face carrying ferromagnetic poles of said stator spaced apart by a pitch, and which mover comprises at least one counter-face facing said side face(s) of the stator beam, in which counter-face electro-magnetic components of the mover are arranged to co-act with the ferromagnetic poles mounted on the stator beam, which elevator comprises an elevator brake. According to the invention the side face of the stator beam facing the mover and/or the counter face of the mover facing the side face of the stator beam comprise(s) a brake surface which form(s) the brake interface of the elevator brake.

According to an aspect, there is provided a control device. The control device is configured to receive data from a passenger traffic system configured in a building, the data comprising information associated with operations for transferring passengers of the passenger traffic system; based on the received data, monitor a change in a quality of service level of the passenger traffic system in transferring the passengers and a change in a passenger traffic pattern in transferring the passengers in the passenger traffic system; and in response to detecting the change in the service level or in the passenger traffic pattern, run one or more simulations of the passenger traffic in the passenger traffic system in the at least one building using the received data in order to trigger at least one operation to change a configuration of the passenger traffic system.

A component monitoring system for monitoring a component of a conveyance system including a conveyance apparatus including: a camera configured to capture a sequence images of the component, the sequence of images being motion data; and a processor configured to determine an evaluation summary of the component in response to at least the motion data.

A monitoring system for controlling self-testing of a traction elevator includes a self-testing process module in communication with a three-phase AC back-up battery power supply. The self-testing process module includes a processor configured to initiate and control a series of steps for performing measurements of the three-phase AC back-up battery power supply, including measurements of the battery supply during a simulated emergency situation (“rescue/evacuation”). The processor is programmed to initiate testing on a defined schedule and transmit test results to a maintenance system (including remotely-located systems) on a routine basis. The monitoring system also includes a display unit providing visual information regarding the status of self-testing processes and their results and a communications unit for transmitting test results to a remote maintenance controller.
