Abstract
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.
Claims20
A sensor controller comprising:
- a processor;
- and
- a memory, the memory having stored thereon computer program code that, when executed by the processor, controls the processor to:
- receive weight data from one or more weight sensors disposed on a cargo vehicle;
- determine that cargo has been removed from the cargo vehicle;
- determine, based on the weight data, an empty weight of the cargo vehicle;
- calibrate the one or more weight sensors based on the empty weight;
- and
- extrapolate total weight of the cargo vehicle based on the weight data.
A system comprising:
- a weight sensor disposed on a cargo vehicle;
- and
- a controller in communication with the weight sensor, the controller comprising a processor and a memory having instructions stored thereon that, when executed by the processor, cause the controller to:
- receive first weight data from the weight sensor, the first weight data being indicative of a weight of a cargo container at a first time;
- receive second weight data from the weight sensor, the second weight data being indicative of a weight of a cargo container at a second time;
- determine a change in weight of the cargo container based on the first weight data and the second weight data;
- determine whether the cargo container is being loaded or unloaded based on the change in weight;
- in response to determining that the cargo container is being unloaded, receive empty weight data from the weight sensor;
- determine, based on the empty weight data, an empty weight of the cargo vehicle;
- and
- calibrate the weight sensor based on the determined empty weight.
A sensor controller comprising:
- a processor;
- and
- a memory, the memory having stored thereon computer program code that, when executed by the processor, controls the processor to:
- receive weight data from one or more weight sensors disposed on a cargo vehicle;
- determine that cargo has been removed from the cargo vehicle;
- determine, based on the weight data, an empty weight of the cargo vehicle;
- calibrate the one or more weight sensors based on the empty weight;
- and
- detect loading or unloading of the cargo vehicle based on determining a pattern of changes to the weight data.
