    摘要: A solenoid valve includes a solenoid coil, a poppet, and a drive circuit. A first semiconductor device of the drive circuit is controlled by a gate signal to control a coil current. A flyback circuit of the drive circuit includes a second semiconductor device in series with a diode. The second semiconductor device is controlled by a flyback control signal to: (i) enable the flyback circuit to maintain the coil current through the solenoid coil when the poppet transitions to a second position, and (ii) disable recirculation of the coil current through the solenoid coil when the poppet transitions to a first position. A controller is configured to transition the poppet to the second position using the gate signal, enable the flyback circuit using the flyback control signal, and reduce at least one of a duty cycle and a frequency of the gate signal when the flyback circuit is enabled.

    摘要: A method for controlled seeding of a parcel of agricultural land by a seeding vehicle having a plurality of individual seeding members each producing a seeding line and being able to interrupt at least one seeding line so as to mark out the parcel, including: providing, in advance, a virtual plan of the parcel with the current portions of the arrangements of seeding lines to be realized; inferring therefrom the trajectories of the seeding vehicle; and controlling the latter to carry out controlled seeding with marking out for these current portions and for the particular trajectories at least during cornering, during U-turns or between the current portions, depending on the trajectories of the rolling members of the vehicle(s) or trailer(s) carrying out the subsequent operation(s) on these current portions.

    摘要: A planting system comprising a camera disposed at a distal end of a seed tube at or below ground level. The system may also include a processor in communication with the camera configured to processes images from the camera, and be configured to conduct image analysis to detect planting conditions including one or more of collapsed trench sidewalls, seed placement, crop residue within the trench, clods within the trench, a collapsed trench, “W” trench, trench size, seed depth, closing wheel operations, soil moisture, and seed bounce. The system may also include a command module in communication with the processor configured to automatically adjust one or more of planter row cleaners, supplemental row unit down force, supplemental closing wheel down force, closing wheel configuration, deployment of seed firmers, timing of application of liquid treatment, and seed meter ejection in response to detected planting conditions.

    摘要: A system (100), method and computer program product for optimization of crop protection. A generator module (120) accesses one or more configuration data structures (220) wherein the one or more configuration data structures include data fields to store crop data (221), advice data (222) related to respective crop data, and crop protection product data (223) related to respective advice. Further, it accesses a plurality of code snippets (230) wherein each code snippet (231, 232, 233) has a condition which relates either to at least one property field of the one or more data structures (220) or to a result of another code snippet, and further includes generic program logic associated with the condition, and wherein each property field is used in the condition of at least one code snippet. The plurality of code snippets is applied to the one or more configuration data structures to generate an advice logic program.
