Portable electronic onboard truck scaling process

Traditional electronic onboard scaling patents teach methods of attaching only permanent components to a vehicle to determine axle or vehicle weight. This patent teaches a method of using a combination of low-cost permanently attached components and a more expensive Portable Electronic Meter that can be shared between the multiple vehicles. The system is comprised of a quick-coupler fitting assembly with a Protective Cap that is permanently attached to a vehicle in a location that a Portable Meter can be attached. Inside the Protective Cap is a memory device that stores historical reference information. The permanently mounted component is non-powered and doesn't require any electrical connection to the vehicle. The Portable Meter has a sensor and battery located inside it and a mating quick-coupler fitting outside it. It is hand carried to a Protective Cap and positioned so cap identification, the reference weights and the pressures within the Caps memory can be transferred between the Protective Cap and a Portable Meter through the unique circuitry created by the components. The Portable Meter is temporarily connected to the quick-coupler of the Meter Connect permanently located on the tractor and/or trailer so that the air bag suspension pressure can be read, converted and displayed to the operator in meaningful axle weight units. If the weight estimate to be made is outside of the pressure range defined by the historical reference data for that axle, the Portable Meter delivers a warning to the driver that the weight estimate is outside of the weight estimating range. If the driver continues with the weight estimate, he does so with a lower level of confidence in the accuracy of the weight estimate being as it has not been modeled by historical reference weights.
