Embodiment Construction

[0027] figure 1 An elevator system 2 is schematically depicted. The cage 4 is arranged in an elevator shaft 6 . The car 4 is operated by a hoist 8 to move up or down. The hoisting machine 8 is arranged in a machine room 9 and includes a mechanical brake 10 and an electric motor 12 . Of course, the elevator system 2 is only shown as an example and can be realized in another way. In another example, lift machine 8 includes a hydraulic motor.

[0028]The first security control unit 20 a is arranged in the machine room 9 . The first safety control unit 20a is used to control the hoisting machine 8 in order to stop the car 4 in case the safety circuit is opened. The second control unit 20b is arranged on the car roof of the car 4 . A further second control unit 20c is arranged at the sump 14 . Most installations of the elevator system 2 will include these three safety control units 20a, 20b and 20c. The safety control units 20a, 20b and 20c are interconnected through a digi...

Abstract

A first safety control unit (20a) of a safety network of an elevator system is provided. The first safety control unit (20a) is configured to determine a first plurality of safety input states of a plurality of safety inputs (202a, 204a), and to determine a safety output state of at least one safety output (212a) from the plurality of first safety input states.

Description

technical field [0001] The invention relates to a first safety control unit, a method of operating the first safety control unit, a second safety control unit, a method of operating the second control unit, and an elevator system. Background technique [0002] The most advanced elevator systems today are equipped with hard-wired safety circuits. These safety circuits are often complex due to the multiple safety contacts and their distribution on the elevator system. Contents of the invention [0003] According to an aspect of the present description, a first safety control unit of a safety network of an elevator system is provided. The first safety control unit includes at least one processor, at least one memory including computer program code, at least one digital communication module, a plurality of safety inputs and at least one safety output. at least one memory and computer program code configured to interact with the at least one processor, at least one digital co...
