摘要： Embodiments of a kernel-level grain monitoring system include a grain camera positioned to capture bulk grain sample images of a currently-harvested grain taken into and processed by a combine harvester, a moisture sensor, and a display device. A controller architecture is coupled to the grain camera, to the moisture sensor, and to the display device. The controller architecture is configured to: (i) analyze the bulk grain sample images, as received from the grain camera, to determine an average per kernel (APK) volume representing an estimated volume of a single average kernel of the currently-harvested grain; (ii) repeatedly calculate one or more topline harvesting parameters based, at least in part, on the determined APK volume and the moisture sensor data; and (iii) selectively present the topline harvesting parameters on the display device for viewing by an operator of the combine harvester.

摘要： A system of detecting loading and unloading of mobile containers such as grain carts utilizes two low pass filters to determine whether the contents of the container are changing by subtracting one filter signal from the other, and using the sign of the difference. Weighing performance is improved by utilizing accelerometers to compensate for measurement dynamics and non-level orientation. Failure and degradation of weight sensors is detected by testing sensor half bridges. Loading and unloading weights can be tied to specific vehicles by utilizing RF beacons.

摘要： In one aspect, the present subject matter is directed to a system for calibrating a harvester. The system includes a yield sensor configured to detect a flow of crop material discharged from the harvester and output data indicative of a flow rate of the crop material, and a wireless communication device configured to receive a transport vehicle communication from a transport vehicle. The transport vehicle communication includes a weight of a crop material in a transport receptacle. The system also includes a computing system in data communication with the wireless communication device. The computing system is configured to determine a time rate of change of the weight and is further configured to determine a yield sensor calibration update based on a time delay determination between the flow rate of the crop materials and the time rate of change of the weight.

摘要： A method for estimating the weight of loads carried by implements may include controlling an implement subject to actual weighing conditions to lift a load and receiving an input indicative of a sensed force associated with lifting the load. The method may further include determining a correlation value indicative of a correlation between first and second force values for lifting a given load with the implement as a function of the actual weighing conditions and as a function of nominal weighing conditions, respectively, where at least one of the actual weighing conditions differs from at least one of the nominal weighing conditions. Furthermore, the method may include determining an adjusted force value for lifting the load based at least in part on the sensed force and the correlation value. Additionally, the method may include estimating the weight of the load based at least in part on the adjusted force value.
