Embodiment Construction

[0031] figure 1 is a perspective view of elevator system 101 including elevator car 103 , counterweight 105 , tension member 107 , guide rail 109 , machine 111 , orientation reference system 113 , and controller 115 . Elevator car 103 and counterweight 105 are connected to each other by tension members 107 . Tension members 107 may include or be configured as, for example, ropes, steel cables, and / or coated steel belts. Counterweight 105 is configured to balance the load of elevator car 103 and to facilitate simultaneous and opposite movement of elevator car 103 within elevator shaft 117 and along guide rail 109 relative to counterweight 105 .

[0032] Tension member 107 engages machine 111 , which is part of the overhead structure of elevator system 101 . Machine 111 is configured to control movement between elevator car 103 and counterweight 105 . The orientation reference system 113 may be mounted on a fixed portion at the top of the elevator shaft 117 , such as on a sup...

Abstract

The invention provides air pressure and acceleration sensor floor correction by elevator status information. A method of monitoring a location of a conveyance apparatus within a conveyance system including: detecting a first location of the conveyance apparatus at a first time using a position reference system; detecting a second location of the conveyance apparatus at a second time using at leastone of a pressure sensor located on the conveyance apparatus and an acceleration sensor located on the conveyance apparatus; and determining that the second location is equivalent to the first location if the second time is within a selected range of the first time.

Description

Background technique [0001] Embodiments herein relate to the field of conveyance systems, and more particularly to methods and apparatus for monitoring the orientation of a conveyance device of a conveyance system. [0002] The precise orientation of conveying equipment within conveying systems such as, for example, elevator systems, escalator systems, and moving walkways can be difficult and / or costly to determine. Contents of the invention [0003] According to an embodiment, a method of monitoring the position of a delivery device within a delivery system is provided. The method includes: detecting a first position of the delivery device at a first time using an orientation reference system; detecting a position of the delivery device at a second time using at least one of a pressure sensor located on the delivery device and an acceleration sensor located on the delivery device a second location; and determining that the second location is equivalent to the first locatio...
