Abstract
An elevator system (2, 102) includes an elevator car (4, 104), a tag detection device (16, 116) arranged to detect the presence of tags (18, 20; 118, 120) in the elevator car (4, 104) and a control system (13). The control system (13) is arranged to determine if the tag detection device (16, 116) detects at least one of a set of associated tags (18, 20; 118, 120) 10 present in the elevator car (4, 104) and, if at least one of the set of associated tags (18, 20; 118, 120) is detected in the elevator car (4, 104), to prevent at least one travel operation of the elevator car (4, 104) until all or none of the set of associated tags (18, 20; 118, 120) is detected to be present in the elevator car (4, 104).
Claims10
An elevator system (2, 102) comprising:
- an elevator car (4, 104);
- a tag detection device (16, 116) arranged to detect the presence of tags (18, 20;
- 118, 120) in the elevator car (4, 104);
- and
- a control system (13) arranged:
- to determine if the tag detection device (16, 116) detects at least one of a set of associated tags (18, 20;
- 118, 120) present in the elevator car (4, 104);
- and
- if at least one of the set of associated tags (18, 20;
- 118, 120) is detected in the elevator car (4, 104), to prevent at least one travel operation of the elevator car (4, 104) until all or none of the set of associated tags (18, 20;
- 118, 120) is detected to be present in the elevator car (4, 104);
- wherein each of the set of associated tags (18, 20;
- 118, 120) comprises a unique identifier and a list of unique identifiers corresponding to other tags in the set of associated tags (18, 20;
- 118, 120), and the association of the set of associated tags (18, 20;
- 118, 120) is determinable by each tag in the set of associated tags (18, 20;
- 118, 120).
A method of operating an elevator system (2, 102) comprising an elevator car (4, 104), the method comprising:
- detecting in the elevator car (4, 104) at least one of a set of associated tags (18, 20, 118, 120);
- preventing at least one travel operation of the elevator car (4, 104) until all or none of the set of associated tags (18, 20, 118, 120) is detected in the elevator car (4, 104);
- wherein each of the set of associated tags (18, 20;
- 118, 120) comprises a unique identifier and a list of unique identifiers corresponding to other tags in the set of associated tags (18, 20;
- 118, 120), and the association of the set of associated tags (18, 20;
- 118, 120) is determinable from each tag in the set of associated tags (18, 20;
- 118, 120) by each tag itself.
