Abstract
An elevator installation includes at least one car 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.
Claims20
An elevator monitoring method comprising:
- generating accelerometer measurements using an accelerometer positioned on a door of an elevator installation;
- wirelessly transmitting at least some of the generated accelerometer measurements from the accelerometer to a communications module;
- and
- processing the measurements with a processor in the communications module to generate maintenance data for initiating a maintenance action.
1 more element
An elevator installation comprising:
- an elevator car disposed in an elevator shaft, the elevator car comprising at least one car door;
- at least one floor door positioned at each of a plurality of floors serviced by the elevator installation;
- a first acceleration sensor attached to the at least one car door or the at least one floor door;
- a first receiver device wirelessly receiving acceleration readings from the first acceleration sensor;
- and
- a processor in the first receiver processing the reading to generate maintenance data for initiating a maintenance action.
3 more elements
An elevator monitoring system comprising:
- a monitor comprising an accelerometer attached to an elevator car door or an elevator floor door to wirelessly transmit accelerometer data and a communications module receiving the transmitted accelerometer data and including a processor processing the accelerometer data to generate maintenance data for initiating a maintenance action.
One or more computer-readable storage media having encoded thereon instructions which, when executed by a processor, cause the processor to perform a method, the method comprising:
- receiving acceleration sensor data, the acceleration sensor data having been generated by an acceleration sensor and wirelessly transmitted from the acceleration sensor to a receiver, the acceleration sensor being attached to a door of an elevator installation;
- and
- based at least in part on the received acceleration sensor data, determining maintenance data for one or more components of the elevator installation.
