Problems solved by technology
[0004] However, such central monitoring and control systems often require highly complex wiring
In addition, significant signal propagation times may occur between the locally provided detection and activatable safety function components and the centrally provided safety monitoring unit, whereby the reaction required by the safety monitoring system to react adequately to the critical situation that has occurred time can be extended considerably
In addition, the transmission of signals and data, for example from several distributed sensors to a single central safety monitoring unit and the central data processing there can result in considerable processing times, which can further extend reaction times

Embodiment Construction
[0044] figure 1 A schematic diagram of an elevator system 1 according to an exemplary form of embodiment of the invention is shown. The elevator system 1 has a drive 3 and a car 5 . The car 5 can be moved by the drive 3 along a travel path in the elevator shaft 7 . Cables 21 guided on pulleys 23 connect the car 5 to the counterweight 17 .
[0045] The elevator system 1 has a plurality of detection and / or activatable safety monitoring components 9a-9p, which are distributed over the entire elevator system and are arranged, for example, in the elevator shaft 7, on its drive 3, or on the side of the elevator shaft 7 or the car 5. various positions on the door.
[0046] The safety monitoring system 11 is used to monitor the elevator system in order, for example, to detect safety-critical situations and to take appropriate measures if necessary. Here, the safety monitoring system 11 is used for monitoring and coordinating the individual safety functional components 9a-9p.

The invention relates to an elevator system, which has: a driver; a car; a plurality of safety functional components; and a safety monitoring system with a plurality of safety monitoring units. The safety-monitoring unit has an input interface for reading in data; a data processing unit for processing the data into a control signal; and an output interface for outputting the control signal to the associated safety function. At least some of the security monitoring units are interconnected. Furthermore, the safety monitoring units are organized in a master-slave hierarchy, wherein one of the safety monitoring units is designed as a master unit and at least one of the safety monitoring units is designed as a slave unit. Due to the decentralized safety monitoring units of the elevator system, which are provided with their own data processing capabilities, and due to the master-slave organization of the elevator system, the elevator system can achieve a high degree of safety, especially for high-rise elevators, with as much Little wiring complexity and thus the lowest possible outlay.
Description
technical field [0001] The invention relates to an elevator system, in particular to an elevator system with a safety monitoring system. Background technique [0002] In general, elevator systems are used to transport people or goods in a vertical direction. In order to avoid hazards to persons or objects, security monitoring systems are usually deployed. These systems monitor the current operating conditions of the elevator system, for example by means of detection of safety functions, ie for example by means of data or signals from sensors or from control devices. For example, monitoring the speed of an elevator car, or the closing status of the doors of an elevator system. In the event of a critical operating situation, the safety monitoring system activates suitable safety functions that can be activated, such as braking devices or fall arrest devices for braking, ie stopping the elevator car. The most stringent requirements are imposed on security monitoring systems ...
