| 摘要 |
The invention relates to a method and an apparatus for interchanging data between at least one sensor unit (4) arranged in a lift shaft (3) of a lift system and a monitoring unit (13) of a service centre (12) which is locally remote from the lift system, wherein a lift car (5) which moves vertically in the lift shaft (3) and on which a first communication unit (1) is arranged is used in the lift system. According to the invention, data are transmitted from the at least one sensor unit (4) to the first communication unit (1) via a first communications network on the basis of the position of the lift car (5) and are stored by the first communication unit (1). The stored data are transmitted from the first communication unit (1) to a second communication unit (2) on the basis of at least one rule and are transmitted from the second communication unit (2) to the monitoring unit (13) via a second communications network. |
