METHOD OF DETERMINING VEHICLE SCALE HEALTH AND SUITABILITY FOR USE VIA WEIGHT TRANSFER PATTERN ANALYSIS

摘要

Methods of determining vehicle scale health and suitability for use via weight transfer pattern analysis. Dynamically changing patterns of measurement values are seen at each load cell of a vehicle weighing scale as a vehicle enters, remains on, and leaves the scale platform thereof during a normal vehicle weighing operation. These patterns may be analyzed to provide an indication of whether a given load cell is operating properly and/or being manipulated to produce a false weight reading.

主权项

1. A method of evaluating the condition of a given load cell of a multiple-load cell vehicle weighing scale, comprising:
identifying a dynamically changing, normal weight transfer pattern of behavior associated with the outputs of each load cell during a typical operation of weighing a vehicle on the vehicle weighing scale or a like vehicle weighing scale; extracting from the weight transfer patterns of behavior, the expected state condition for each of the load cells of the scale for different vehicle positions that will normally exist during a typical vehicle weighing operation; comparing the actual load cell state conditions observed during a given vehicle weighing operation to the expected load cell state conditions; and analyzing the results of the comparison for each load cell to determine whether a given load cell of the vehicle weighing scale is operating properly.
