Distributed control system for an elevator system
First Claim
1. An elevator system having an elevator shaft and at least one elevator cab which can move in the elevator shaft, the elevator system comprising:
- a distributed control system having a first evaluation unit, respectively associated with the at least one elevator cab, and has at least one second evaluation unit, associated with the elevator shaft;
a bus link connecting the first evaluation unit and the at least one second evaluation unit to one another;
the first evaluation unit comprising a set of limit curves containing limit curves for the actuation of a braking device and/or a safety gripping device that are calculated and scaled in line with a current operating state, the first evaluation unit being configured to trigger the safety gripping device or the braking device if one of the limit curves is exceeded; and
wherein defined ends of the limit curves limit a scope of movement for the at least one elevator cab.

Abstract
An elevator system including an elevator shaft and at least one elevator cab which can move in the elevator shaft. The elevator system has a distributed control system having a first evaluation unit, respectively associated with the at least one elevator cab, and has at least one second evaluation unit, associated with the elevator shaft. A bus link connects the first evaluation unit and the at least one second evaluation unit to one another. The first evaluation unit has a set of limit curves containing limit curves for the actuation of a braking device and/or a safety gripping device that are calculated and scaled in line with a current operating state, the first evaluation unit being configured to trigger the safety gripping device or the braking device if one of the limit curves is exceeded. Defined ends of the limit curves limit a scope of movement for the at least one elevator cab.

20. A method for controlling an elevator system, comprising the steps of:
-
a first evaluation unit calculating and scaling at least one limit curve in line with a current operating state, wherein the at least one limit curve associates an associated speed with an arbitrary position for an elevator cab in an elevator shaft; controlling the elevator cab in line with the respective values of the at least one limit curve; and triggering by the first evaluation unit a safety gripping device or a braking device if one, of the at least one limit curve is exceeded, and defined ends of the at least one limit curve limiting a scope of movement for the elevator cab. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
