| 摘要 |
The invention relates to a lift system (1) comprising a plurality of cars (2), a shaft system (3), a drive system for separately moving the cars (2) within the shaft system (3), and a safety system having a plurality of safety nodes, which safety system is designed to transfer the lift system (1) into a safe operating state when an operating state of the lift system (1) deviating from the normal operation is established. The cars (2), the shaft system (3) and the drive system thereby form a respective functional unit. One of the safety nodes is assigned a respective one of the functional units, wherein the safety nodes are each connected to at least one of the further safety nodes via an interface for transmitting data. The safety nodes each comprise at least one sensor for determining an operating parameter of the corresponding assigned functional unit, and a control unit that is designed to evaluate the operating parameter determined by the at least one sensor of the respective safety node, and to make an establishment relating to an operating state deviating from the normal operation, based on the data transmitted from the at least one further safety node. |
