Problems solved by technology

[0006] The large signal flow with safety-relevant signals in modern complex elevator installations results in a very large cabling overhead, especially in ultra-modern elevators in which two or more elevator cars are moved and controlled independently of each other in one shaft equipment is very expensive and results in a considerable cost factor

Embodiment Construction

[0056] figure 1 An elevator system 10 is shown with an elevator shaft 11 and an elevator car 12 that can travel in vertical direction in the elevator shaft 11 . The elevator car 12 is connected via a traction rope 14 to a drive 15 and a counterweight 16 , wherein the drive 15 drives the traction rope 14 and the elevator car moves upward or downward depending on the drive direction of the traction rope 14 . The counterweight 16 moves accordingly in the opposite direction. Furthermore, the elevator shaft 11 comprises a plurality of landings 13a and 13b. At these stops, the elevator car 12 can be stopped so that passengers can enter and exit the elevator car 12 . The shaft pit 17 forms the lower end station of the elevator shaft 11 .

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

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...
