Abstract

The embodiments of the invention relate to devices, methods and programs for monitoring, processing and adjusting an elevator emergency stopping event. Devices, methods and computer programs for monitoring, processing and / or adjusting of elevator emergency stopping events are disclosed. At least some of the disclosed embodiments allow measuring automatically the performance of an elevator emergency stopping event protection function, and the invention can be utilized together with manual checks for adjusting parametrization of the elevator emergency stopping event protection function. The invention further allows separate safety parameters for up and down direction. Measurements can be done separately to both directions and related safety parameters can be adjusted based on those.

Description

technical field [0001] The present invention relates to the field of elevators, and more particularly, to the monitoring, processing and / or adjustment of elevator emergency stop events, and related devices, methods and computer programs. Background technique [0002] Elevators have electromechanical brakes that are applied to the traction sheave or axis of rotation of the elevator to stop movement of the elevator, and thus the elevator car driven by the elevator. Lifts usually have two electromechanical brakes. The brakes are typically sized to stop and hold an elevator car with a 125% load (ie 25% overload) in the event of an emergency stop event. The braking torque is related to the friction between the brake pads and the brake linings. Thus, wear of the brake pads may result in a reduction in friction / braking torque and thus increase the braking distance associated with an emergency stop event. [0003] Traditionally, elevators are driven via wire ropes running through...
