    摘要： A monitoring system for a passenger conveyor including: at least one acceleration sensor provided on a movable component of the passenger conveyor, wherein the moveable component moves in a closed loop path (P) when the passenger conveyor is in use; a fault detection sensor associated with the or each acceleration sensor and configured to provide data indicative of a fault in the moveable component. The monitoring system includes a controller configured to: receive data from the or each acceleration sensor; monitor a gravity vector (V) of the or each acceleration sensor; determine a direction of travel of the or each acceleration sensor; determine a current location of the or each acceleration sensor based on the monitored gravity vector (V) and the determined direction of travel; detect a fault from the data received from the or each fault detection sensor; identify a location of the detected fault.

    摘要： A passenger conveyance system (2, 102, 202) is provided which includes a first component (12, 112, 212) arranged to rotate about a first rotation axis A1 and a second component (16, 116, 216) arranged to rotate about a second rotation axis A2; at least one magnet (20,120, 220); and at least one sensor (24, 124, 224). Either the at least one sensor (24, 124, 224) or the at least one magnet (20, 120, 220) is fixed to the first component (12, 112, 212). The sensor (24, 124, 224) is arranged to measure a displacement to the at least one magnet (12, 112, 212), and the system (2, 102, 202) is arranged to use the measured displacement to determine information indicative of the alignment of the first and second components (12, 112, 212; 16, 116, 216).

    摘要： A drive system (35) for a people conveyor (1) comprises a conveyance chain (15) including a plurality of chain links (36) connected to each other; a plurality of legs (38) configured for connecting the conveyance chain (15) with the conveyance elements (13); and a plurality of levers (40). Each leg (38) is connected to at least two different chain links (36) by at least two of the levers (40). Each of the levers (40) is pivotably connected to one of the chain links (36) and pivotably connected to one of the legs (38).

    摘要： A polygon compensation coupling system (30; 40; 60) comprises a first rotatable element (31; 41; 61), a second rotatable element (32; 42; 62a, 62b), and at least one linkage coupling the first rotatable element (31; 41; 61) with the second rotatable element (32; 42; 62a, 62b). The linkage comprises at least one first coupling element (34a; 44a; 64a) pivotably coupled to the first rotatable element (31; 41; 61) and at least one second coupling element (34b; 44b; 64b) pivotably coupled to the second rotatable element (32; 42; 62b). The first and second coupling elements (34a, 34b; 44a, 44b; 64a, 64b) are pivotably coupled to each other at a hinge point, the hinge point is configured to move along a compensation curve varying the coupling between the first rotatable element (34a; 44a; 64a) and the second rotatable element (32; 42; 62b).
