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.

The present invention provides an improved weigh-in-motion scale. A slight increase in the thickness of a an upper, flexibly-deformable metal plate e.g., having a thickness of about 0.604 inches to about 0.756 inches in a thin, flexibly-deformable plate system coupled with a change in the transverse locations of the load cells each of the strain gauge channels is spaced e.g., by an amount of about 52 % to about 54 % of the distance from the center line of the bottom or lower metal plate to the respective longitudinal edge of the bottom or lower metal plate, provides the improved weigh-in-motion scale, which is capable of weighing substantially heavier loads than previously known weigh-in-motion scales. In use, as weight is applied to the wcigh-in-motion scale, the upper flexibly-deformable metal plate elastically bends. The strain gauges thus provide a changing resistive value proportional to the bending of the flexible element and the weight applied, to generate signals to the Wheatstone bridge circuit, which then provides output signals from the Wheatstone bridge circuit, which are proportional to the force applied to the upper flexibly-deformable metal plate.
