An illustrative example embodiment of a device for communicating information regarding an elevator car that moves along a vertical path includes at least one sensing portion configured to be supported on the elevator car and to sense at least one characteristic of the elevator car. A transmitter is configured to transmit a wirelessly communicated output indicating at least one condition based on the sensed characteristic. The transmitter is configured to use a first transmit power when the device is at a first location along the vertical path and to use a second, different transmit power when the device is at a second, different location along the vertical path.

According to an aspect, a method includes monitoring a plurality of vibration data by a vibration monitoring beacon and determining that the vibration monitoring beacon has been installed at a service location based on detecting an installation characteristic signature in the vibration data. The vibration monitoring beacon can transition into a learning mode based on determining that the vibration monitoring beacon has been installed at the service location. The method can also include monitoring for a learning mode termination event and transitioning the vibration monitoring beacon from the learning mode to a normal operation mode based on detecting the learning mode termination event.

Vibration monitoring beacon mode detection and transition

A method of calibrating a monitoring device () for monitoring movement of a movable component () of an elevator system () comprises detecting () a travel time (Δt) between a starting time (t) and a stopping time (t') as well as acceleration (a(t)) of at least one movement of the movable component (); determining () a travel distance of the movable component () by integrating the detected acceleration (a(t)) twice with respect to the detected travel time (Δt); correlating () the determined travel distance (s) with the detected travel time (Δt) to form a pair of travel time and travel distance; and storing () the pair of travel time and travel distance (Δt,s) as part of a travel profile ().

Device and method for monitoring an elevator system

A method of monitoring a conveyance apparatus within a conveyance system including: detecting, using a sensing apparatus, at a first conveyance apparatus location at least one of an acceleration of the conveyance apparatus, temperature data of the conveyance system, and pressure data proximate the conveyance apparatus; determining a health level of the conveyance system at the first conveyance apparatus location in response to at least one of the acceleration of the conveyance apparatus, the temperature data of the conveyance system, and the pressure data proximate the conveyance apparatus; and displaying the health level for the conveyance system at the first conveyance apparatus location on a display device.

An illustrative example elevator sensor device includes at least one sensor supported on a door of an elevator car. The sensor provides an output including an indication of at least movement of the door along at least one axis and movement of the elevator car along at least one axis. A processor associated with the at least one sensor receives the output and determines at least one characteristic of the movement of the door based on the indication of the movement of the door. The processor also determines a location of the elevator car where the movement of the door occurs based on the indication of movement of the elevator car.

Elevator car and door motion monitoring

A method of monitoring a conveyance system is provided. The method including: monitoring vibratory signatures along a first axis of a conveyance apparatus of a conveyance system; detecting a vibratory signature along the first axis about equivalent to a vibratory signature of significant event; and examining vibratory signatures for a secondary event along at least one of the first axis and a second axis of the conveyance apparatus for at least one of a selected time period after detection of the significant event and a selected time period before detection of the significant event.

Monitoring of conveyance system vibratory signatures

Methods and systems for determining elevator car locations are provided. Aspects includes a sensor affixed to a moving component of an elevator system, wherein the sensor is operated by a controller and wherein the controller is configured to determine that the elevator car is in motion based at least in part on the sensor. A direction of the elevator car is determined while the elevator car is in motion based at least in part on the sensor. Sensor data associated with the elevator car is collected while the elevator car is in motion, wherein the sensor data includes a travel time while the elevator car is in motion. Elevator car travel data is accessed from a travel time profile associated with the elevator car and the travel time is compared to the elevator car travel data to determine a location of the elevator car in a hoistway.

Elevator sensor system floor mapping

A method of monitoring a conveyance apparatus within a conveyance system including: detecting a first atmospheric air pressure within the conveyance system proximate the conveyance apparatus; detecting a second atmospheric air pressure within the conveyance system proximate the conveyance apparatus; determining a change in atmospheric air pressure proximate the conveyance apparatus in response to the first atmospheric air pressure and the second atmospheric air pressure within the conveyance system; and determining at least one of a location of the conveyance apparatus and a direction of motion of the conveyance apparatus within the conveyance system in response to at least the first atmospheric air pressure and the second atmospheric air pressure.
