Abstract
Official abstract text for this publication.
An elevator installation includes at least one car door or floor door and at least one acceleration sensor mounted on the door. The sensor generates measurements that are transmitted wirelessly to a communications module for determining maintenance data.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: generating accelerometer measurements using an accelerometer positioned on an elevator door; wirelessly transmitting the generated accelerometer measurements from the accelerometer to a receiver; and generating maintenance data using the transmitted accelerometer measurements. 2. The method of claim 1 , the elevator door comprising an elevator car door. 3. The method of claim 2 , the generated accelerometer measurements indicating accelerations of an elevator car. 4. The method of claim 2 , the generated accelerometer measurements indicating accelerations of the elevator car door. 5. The method of claim 1 , the receiver being mounted in an elevator shaft. 6. An elevator installation, comprising: an elevator car disposed in a shaft, the elevator car comprising a car door; a floor door positioned at a floor served by the elevator car; an acceleration sensor attached to the car door or to the floor door; a receiver that wirelessly receives accelerometer measurements transmitted from the acceleration sensor; and a processor that generates maintenance data using the transmitted accelerometer measurements. 7. The elevator installation of claim 6 , the acceleration sensor being attached to the car door and the receiver being attached to the elevator car. 8. The elevator installation of claim 6 , the receiver being attached to a wall of the shaft. 9. The elevator installation of claim 6 , the receiver being located outside of the shaft. 10. One or more computer-readable storage media having encoded thereon instructions that, when executed by a processor, cause the processor to perform a method, the method comprising: generating accelerometer measurements using an accelerometer positioned on an elevator door; wirelessly transmitting the generated accelerometer measurements from the accelerometer to a receiver; and generating maintenance data using the transmitted accelerometer measurements.
