Example Embodiment

[0056] figure 1 An elevator system 10 having an elevator hoistway 11 and an elevator car 12 that can travel in the vertical direction in the elevator hoistway 11 is shown. The elevator car 12 is connected to a drive 15 and a counterweight 16 via a halteseil 14, wherein the drive 15 drives the traction rope 14 and the elevator car moves up or down according to the driving direction of the traction rope 14. The counterweight 16 moves in the opposite direction accordingly. In addition, the elevator shaft 11 includes a plurality of stops 13a and 13b. The elevator car 12 can be stopped at these stops so that passengers can enter and exit the elevator car 12. The hoistway pit 17 forms the lower end station of the elevator hoistway 11.

[0057] figure 2 A schematic block diagram of the secure bus connection 22 according to the invention is shown. The safety bus connection 22 mainly connects the first analysis unit 21 and the second analysis unit 23, wherein the first analysis unit 2...

Abstract

The invention relates to an elevator system (10) having an elevator shaft (11) and at least one elevator cabin (12) movable inside the elevator shaft (11), said elevator system further comprising a decentralized control system having a first analysis unit (21) associated with one of the at least one elevator cabin (12), a second analysis unit (23) associated with the elevator shaft (11), and a number of third analysis units (26, 29). The first (21), second (23), and third (26, 29) analysis units are connected to one another via a bus connection (22), wherein signal transmission occurs via thebus connection (22) using a safety protocol such that the transmission of safety-relevant data is allowed between the analysis units (21, 23, 26, 29). The safety protocol is structured such that transmission errors are detected and data corruption is indicated. Moreover, the first analysis unit (21) associated with the elevator cabin (12) is connected to sensors (33) for securely detecting the position of the elevator cabin (12), allowing control of safety devices (34, 35) of the elevator system (10). The second analysis unit (23) is connected to a drive (15) of the elevator system (10).

Description

technical field [0001] The invention relates to an elevator system with an elevator shaft and at least one elevator car that can be moved in the elevator shaft. In particular, the invention relates to an elevator system with a decentralized elevator control which enables a safety-related identification and processing of signals and data acquired in the elevator system. Background technique [0002] Elevator systems with decentralized control schemes have been known in elevator production for many years. A typical elevator control of this type consists of a signal and data acquisition device in the elevator car which is connected via cables to an externally operable operator control console which is usually arranged in the uppermost landing area of ​​the elevator shaft. In addition to the on-off switch, there are devices necessary for emergency measures on the operating console. Usually the operating console is connected in terms of communication with a central station whic...
