Assignee: OTIS ELEVATOR COMPANY
Field: Handling (Mechanical engineering)
Classification: CPC B  G | IPC B

Claim 14:
15. A computer program product tangibly embodied on a computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations of monitoring a conveyance apparatus within a conveyance system, wherein the conveyance system is an elevator system and the conveyance apparatus is an elevator car or wherein the conveyance system is an escalator system and the conveyance apparatus is a moving stair or wherein the conveyance system is a moving walkway and the conveyance apparatus is a moving pallet, the operations comprising:
detecting a vibratory signature at a primary location during a commissioning phase using a primary sensing apparatus located at the primary location;
detecting a vibratory signature at a secondary location during the commissioning phase using a secondary sensing apparatus located at the secondary location;
determining a transfer algorithm in response to the vibratory signature at the primary location during the commissioning phase and the vibratory signature at the secondary location during the commissioning phase;
detecting a vibratory signature at the primary location during a normal operation phase using the primary sensing apparatus located at the primary location; and
converting the vibratory signature at the primary location during the normal operation phase to a vibratory signature at the secondary location during the normal operation phase using the transfer algorithm;
wherein the secondary sensing apparatus is removed from the conveyance system prior to the detecting the vibratory signature at the primary location during a normal operation phase using the primary sensing apparatus located at the primary location; and converting the vibratory signature at the primary location during the normal operation phase to a vibratory signature at the secondary location during the normal operation phase using the transfer algorithm.
