摘要： A detection arrangement for detecting a wear status of a chopping knife arrangement of a chopping device provided for processing a product flow, wherein the chopping device has a revolving chopping drum receiving the chopping knife arrangement and at least one shear bar which cooperates with the chopping knives, with a sensor arrangement which has a magnetic exciter arrangement and a flux conducting device magnetically coupled thereto. The sensor arrangement provides a pole arrangement which forms at least one magnetic pole with a pole surface for conducting magnetic flux, wherein at least a portion of the chopping knife passes the pole arrangement during a rotation of the chopping drum. A voltage induced when a chopping knife arrangement passes the sensor arrangement forms the measured magnetic value, which is used by the evaluation unit to determine the state of wear of the chopping knife arrangement.

摘要： A forage harvester is disclosed. The forage harvester has at least one work assembly for processing harvested material of a crop, which includes grain components. In operation, the harvested material is transported in a harvested material flow along a harvested material transport path through the forage harvester. The forage harvester further includes a corn cracker as a work assembly and a control assembly that includes an optical measuring system. The optical measuring system has a camera for recording image data of the harvested material, with the camera being positioned after the corn cracker. The control assembly, using an image recognition routine, determines image regions assigned to a comminuted grain component in the image data, determines geometric properties of the assigned comminuted grain components based on the image regions, and determines an indicator of a processing quality of the comminuted grain components from the geometric properties.

摘要： A forage harvester has multiple working elements for carrying out a crop handling process, a drive system which is divided into a main drive train that includes mechanically driven working elements, and an auxiliary drive train that includes hydraulically driven working elements, a driver assistance system which comprises a memory for storing data and a computing device for processing data stored in the memory, as well as a graphical user interface. The working elements consist of at least one adjustable crop handler, at least one actuator system for adjusting and/or actuating the crop handler, and a control unit for controlling the actuator system. The working element is designed as an automatic adjuster whose mode of operation can be optimized by the driver assistance system. The driver assistance system feeds a throughput-proportional load signal, which can be determined by at least one sensor system, to the particular automatic adjuster.

摘要： A method and a system for determining an indicator of processing quality of an agricultural harvested material using a mobile device is disclosed. A computing unit analyzes image data of a prepared sample of harvested material containing grain components and non-grain components in an analytical routine to determine the indicator of the processing quality of the agricultural harvested material. Further, the computing unit uses a trained machine learning model in the analytical routine to perform at least one step of determining the indicator of the processing quality of the agricultural harvested material and that the computing unit adjusts at least one machine parameter of the forage harvester based on the indicator of processing quality.

摘要： An agricultural work machine has a crop collection arrangement for separating and collecting crops from field vegetation, which crop collection arrangement has at least one crop cutting device, a crop conveying device arranged downstream thereof and a crop intake device arranged downstream thereof, and having a control device which has at least one sensor unit for optically detecting a crop flow, an image processing unit for processing images which are generated by the sensor unit based on the optically detected crop flow, and a data output unit for displaying the images processed by the image processing unit. The image processing unit generates a velocity characteristic map and a directional change characteristic map based on the images generated by the sensor unit. The two characteristic maps are utilized jointly or each individually by the control device to control processes in the agricultural work machine and/or in the crop collection arrangement.

摘要： A device and a method for determining a portion of broken grain and/or non-grain components in a stream of harvested material is disclosed. The device includes a camera to generate images of the stream of harvested material and an evaluation unit to estimate the portion in an image supplied by the camera. The evaluation unit includes a first-order classifier to estimate a first parameter of the stream of harvested material, and a plurality of second-order classifiers assigned to various values of the first parameter to estimate the portion in a stream of harvested material that has the assigned parameter value. The evaluation unit, with assistance of the first-order classifier, estimates a value of the first parameter using a first number of images of the camera, and then selects the second-order classifier assigned to the value of the first parameter to estimate the portion with assistance of the selected second-order classifier.

摘要： An agricultural harvesting machine, with at least one work assembly and a monitoring assembly, is disclosed. The agricultural harvesting machine transports harvested material in a harvested material flow along a harvested material transport path. The monitoring assembly includes an optical measuring system positioned on the harvested material transport path and an evaluation device configured to determine at least one harvested material parameter. The optical measuring system includes a first optical sensor that senses spatially-resolved image data indicative of visible light in a first section and second optical sensor that senses image data indicative of invisible light in a second section that at least partly overlaps the first section. The evaluation device correlates the image data for the overlapping section from the first optical sensor and from the second optical sensor and determines, based on the correlation, at least one harvested material parameter.
