    摘要: A sensor system for determining soil characteristics is disclosed herein. The sensor system includes a ground engaging device for coupling to an agricultural implement. The ground engaging device includes at least one disc member having an aperture and an elongate shaft extending through the aperture. A first sensor unit is arranged on a sensing surface of the disc member and is configured to measure forces acting on the disc member. A second sensor unit is arranged on the elongate shaft and is configured to measure forces acting on the shaft. A processor is communicatively coupled to each of the first and second sensor units. The processor is configured to generate an output signal indicative of a soil characteristic based on the forces measured.

    摘要: Embodiments herein relate to a time domain depth sensor system and method for determining a depth of a ground engaging device in soil. The sensor system may include a signal transmission element arranged on an outer periphery of a ground engaging device that is adapted to penetrate soil. The signal transmission element can be arranged to receive and transmit an electrical signal that is responsive to impedance discontinuities detected by a pulse detector. The pulse detector is configured to detect a first and a second reflected signal corresponding to a sensed impedance discontinuities at a first and a second soil location. An electronic data processor is communicatively coupled the pulse detector and is configured to determine the depth of the ground engaging device in the soil based on a difference between a first time of propagation of the first reflected signal and a second time of propagation of the second reflected signal.

    摘要: A sensing system for obtaining a gradient of soil properties in real-time as a function of soil depth is disclosed herein. The sensing system includes a support structure coupled to an agricultural implement and which is rotatable about a rotational axis relative to a frame of the agricultural implement. A sensor is arranged on a surface of the support structure and configured to generate an output signal indicative of the measured soil property based on a sensed a capacitance change corresponding to a change in a dielectric property of a measured soil sample with which the sensor interacts. A measuring unit is coupled to the at least one sensor and processes the output signal generated by the at least one sensor to generate a gradient profile of the soil properties in real-time as a function of one or more depths for display on a user interface.

    摘要: A sensor for determining soil properties is disclosed herein. The sensor includes a ground engaging structure adapted for coupling to an agricultural implement and to penetrate soil at a predetermined depth. An electrode assembly is disposed on a sensing surface of the ground engaging structure that includes a plurality of electrode sensing units. The plurality of electrode sensing units are configured to selectively generate a series of electric fields that project outwardly into the surrounding soil in response to receipt of an excitation signal and sense changes in the electric field corresponding to a change in a measured electrical output signal that is used to determine one or more soil properties during movement of the agricultural implement in a field.
