Embodiment Construction

[0033] figure 1 is a perspective view of elevator system 101 comprising elevator car 103 , counterweight 105 , tension member 107 , guide rail 109 , machine 111 , position reference system 113 and controller 115 . The elevator car 103 and the counterweight 105 are connected to each other by means of tension members 107 . Tension members 107 may comprise 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 movement of elevator car 103 relative to counterweight 105 within elevator hoistway 117 and along guide rail 109 simultaneously and in opposite directions.

[0034] 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 . Position reference system 113 may be mounted on a fixed portion at the top of elevator shaft 1...

Abstract

An elevator system comprising: an elevator car configured to travel in a hoistway, the elevator car including elevator car doors; a controller configured to control movement of the elevator car; configured to sense at least one of operating conditions of the elevator system a sensor; and a sensor interface configured to detect an outage condition of the elevator system in response to an operating condition.

Description

technical field [0001] Embodiments described herein relate generally to elevator systems, and more particularly, to elevator systems using sensor-based outage detection. Background technique [0002] From time to time, elevator systems will go into shutdown due to various events such as overspeed conditions, machine failures, controller failures, and the like. In some cases, maintenance personnel cannot access the elevator controller in order to determine the exact status of the elevator system. This can happen when the maintenance personnel are not related to the manufacturer of the elevator system. In these situations, maintenance personnel can find it difficult to determine the current state of the elevator system. Contents of the invention [0003] According to an embodiment, an elevator system includes: an elevator car configured to travel in a hoistway, the elevator car including elevator car doors; a controller configured to control movement of the elevator car; a...
