摘要： A method includes positioning, by a robot, a servo press proximate one or more reference identifiers of the vehicle. The method includes applying, by the servo press, a known weight to the vehicle. The method includes calibrating the payload monitoring system of the vehicle based on data from a plurality of payload sensors in response to applying the known weight.

摘要： The disclosed technology relates to systems and methods for weighing transportation vehicles and cargo and determining their load state. The disclosed technology can include a sensor controller configured to received one or more sensor readings from weight sensors on a cargo vehicle. The sensor controller can determine an inclination and/or deflection of the cargo vehicle and modify the sensor readings based on the inclination and/or deflection. The sensor controller can calculate a weight of cargo carried by the cargo vehicle based on the modified sensor readings.

摘要： A hysteresis compensation method, in which a hysteresis error is calculated for an obtained weighing value by means of an ideal hysteresis error model, and an ideal compensation value is further calculated by means of an ideal hysteresis compensation model, wherein by using a proportional relationship between a system hysteresis error model established in hysteresis calibration and the ideal hysteresis error model, the ideal compensation value is corrected to a final compensation value. The method establishes a mapping relationship between the system's own hysteresis compensation and the ideal state hysteresis compensation, and realizes the transformation of a complicated hysteresis error compensation situation into an ideal hysteresis error compensation situation. The method not only has a good compensation effect for the hysteresis error compensation under ideal situations, but also can obtain an excellent hysteresis compensation effect under complicated hysteresis situations.

摘要： A method at a sensor apparatus affixed to a transportation asset. The method includes calibrating the sensor apparatus by initiating a vertical impact at the transportation asset, measuring spring oscillation and creating a model of the transportation asset. The method further includes detecting, subsequent to the calibrating, an impact event at the sensor apparatus. The method further includes measuring spring oscillation due to the impact event at the sensor apparatus and using the measured spring oscillation in the model created during calibration to create a load mass estimate for the transportation asset.

摘要： A weigh platter assembly includes a weigh platter and a parallax based off-platter detection assembly having a light emission assembly, a light detection assembly, and a controller. The light emission assembly has a light source to emit a light beam along a lateral edge of the weigh platter. The light detection assembly detects at least a portion of the light beam reflected from an object extending across the light beam and includes a sensor offset from the light source and an aperture positioned in front of the sensor and configured to limit a field of view of the sensor along the lateral edge between proximal and distal edges of the weigh platter. The controller is configured to provide a first signal in response to a first value received from the sensor and to provide a second signal, different from the first signal, in response to a second value.

摘要： Apparatus and related methods are provided in a surface acoustic wave (SAW) scale for measuring weight of a load. A processor reads a first frequency of a SAW delay line operating in a first mode. A push oscillator injects a frequency similar to but different than the first frequency in order to cause the SAW delay line to operate in a second mode, and the processor reads a second frequency of the SAW delay line operating in the second mode. A difference between the frequencies is calculated and compared to values in a stored table to determine the first mode at which the SAW delay line was operating. Based on a determination of the first mode and the first frequency, the weight of the load is determined. This determined weight can be used to recalibrate an auxiliary weight sensor.
