Data Analysis

QarVision™ stores all data in an Access database.  Easy-to-use graphing and reporting tools retrieve the data for any specified time period, and display it in the format most useful for analysis.


Graphs of acceleration data show the smoothness of elevator movement.  Problems with jerk, jitter, etc. can be easily identified.


Graphing door activity along with acceleration of each trip reveals any problem with motion while the door is open. Graphing door activity also allows a quick visual scan to check for problems in opening or closing times.


Speed graphs help verify that the elevator is properly adjusted.


Reports help find anomalies and identify problems quickly. They can be run for any time period, to identify trends and changes in operating parameters. The image above shows just a portion of a complete report.
