Abstract:
A method of monitoring motion of a conveyance apparatus within a conveyance system is provided. The method including: detecting a first atmospheric air pressure proximate the conveyance apparatus at a first time and a second atmospheric air pressure proximate the conveyance apparatus at a second time using the pressure sensor located on the conveyance apparatus; determining a change in atmospheric air pressure proximate the conveyance apparatus in response to the first and second atmospheric air pressure; detecting a height change of a conveyance apparatus in response to at least the change in atmospheric air pressure; and confirming or disconfirming the height change using at least one of a rate of change in atmospheric air pressure prior to the first time, an acceleration of the conveyance apparatus, a rate of change in static atmospheric air pressure, a rate of change in temperature, and a rate of change in relative humidity detection.
