Abstract
A method of detecting maintenance requirements of a system for conveying a car through a passageway is provided. The method comprising: detecting pressure data for at least one or more locations along a passageway using a pressure sensor; comparing the pressure data to benchmark pressure data for each of the one or more locations; determining a pressure data variance at a first location of the one or more locations in response to the pressure data and the benchmark pressure data; and identifying an identity of a car stop location door system located at the first location when the pressure data variance is greater than a selected tolerance.

A method of detecting maintenance requirements of a system for conveying a car through a passageway, the method comprising:
- detecting pressure data for at least one or more locations along a passageway using a pressure sensor;
- comparing the pressure data to benchmark pressure data for each of the one or more locations;
- determining a pressure data variance at a first location of the one or more locations in response to the pressure data and the benchmark pressure data;
- and
- identifying an identity of a car stop location door system located at the first location when the pressure data variance is greater than a selected tolerance.
A method of detecting maintenance requirements of an elevator system, the method comprising:
- detecting pressure data for at least one or more locations along an elevator hoistway using a pressure sensor;
- comparing the pressure data to benchmark pressure data for each of the one or more locations;
- determining a pressure data variance at a first location of the one or more locations in response to the pressure data and the benchmark pressure data;
- and
- identifying an identity of an elevator landing door system located at the first location when the pressure data variance is greater than a selected tolerance.
A controller for an elevator system, the controller comprising:
- a processor;
- and
- a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising;
- detecting pressure data for at least one or more locations along an elevator hoistway using a pressure sensor;
- comparing the pressure data to benchmark pressure data for each of the one or more locations;
- determining a pressure data variance at a first location of the one or more locations in response to the pressure data and the benchmark pressure data;
- and
- identifying an identity of an elevator landing door system located at the first location when the pressure data variance is greater than a selected tolerance.
