    Device for detecting the condition of a substrate
    The invention relates to a device for detecting the nature of a substrate, an agricultural machine with such a device and a method for operating such an agricultural machine.
    From the state of the art in the field of geophysics, it is known to use floor sensors which detect the nature of a substrate on the basis of electromagnetic induction (EMI). In this case, a primary field is generated by an electromagnetic transmitting coil, which induces a secondary electromagnetic field in the ground, depending on the nature of the ground, which is recorded and evaluated by one or more receiving coils in the surface region.
    From the signals of the receiver coils, conductivity values result, from which, depending on the configuration and sensitivity of the coils, the condition of the substrate, for example the density, the water saturation and the soil type, can be determined at a depth of a few centimeters to several meters.
    Since the EMI technology, in contrast to other geophysical methods, can be used in almost all underground situations and is also relatively inexpensive to purchase, it has become established as a measuring method in precision farming. The main field of application of established systems is to collect soil inhomogeneities laterally in their own test drives and then to make them available to the farmer in the form of maps and plans.
    In some cases, motorized systems are used, which are mounted on a usually specially designed attachment system and pulled over the examination surface. The soil sensor is mounted behind the tractor and it must be a large distance of the ground sensor are adhered to the towing vehicle in order to prevent a quality-reducing measurement noise or other errors in data collection as possible.
    In the operation of known ground sensors, the data collection takes place independently of farmer farming rides, as the operation of the system and the evaluation of the data requires specialized personnel. From the data acquisition to the delivery of the maps with the evaluated soil data runs thus a complex process, in which the farmer is not involved.
    The object of the invention is to remedy the disadvantages of existing systems and to realize a device for detecting the nature of a substrate and a method for operating such a device, which enable the farmer to capture soil information flexibly and independently during the agricultural work journey and to use these simultaneously or subsequently for a control of agricultural machinery.
    This object is achieved by a device, an agricultural machine and a method for operating an agricultural machine according to the independent claims.
    The inventively proposed device comprises at least one transmitting coil and at least one, preferably four, receiving coils, wherein the transmitting coil for generating an electromagnetic primary field and the receiving coil for receiving the induced in the ground by the primary field secondary electromagnetic field is set up. Both the transmitting coil and the receiving coil are arranged in a front or ballast weight. Such front or ballast weights are mounted on agricultural tractors on a suspension at the front of the tractor and serve on the one hand to improve the traction of the tractor and on the other hand to compensate for unequal load by heavy mounted on the rear of the tractor units. They are usually cast from concrete and have a weight of about one ton.
    By arranging the transmitting and receiving coil in a front weight is achieved that the detection of the nature of the substrate can already be done during a working drive of the tractor. Since the front weights are usually cast from concrete, maximum protection and protection of the sensitive electronic components is achieved. The rigid connection between the tractor and the sensor components also reduces motion-induced disturbances.
    According to the invention, provision may be made for a sensor receiving area for receiving the transmitting and receiving coils and one of the spaced apart electronics receiving areas for receiving the control electronics to be provided in the front weight. This has the advantage that the transmitting and receiving coils can be arranged on specific areas of the front weight, preferably in the front lower area.

    Particularly advantageous is an embodiment of the invention in which the sensor receiving area and electronics receiving area are separated by a shielding plate shielding electromagnetic radiation. This shielding plate may preferably be a steel plate or a plate of another electromagnetic radiation shielding material. This ensures that the transmitting and receiving coils arranged in the sensor receiving region are not influenced by disturbing electromagnetic signals, in particular from the tractor itself located in the immediate vicinity. In addition, a shield against mechanical influences is achieved by the shielding. According to the invention, a connection can also be provided in order to connect the shielding plate to an external electrical grounding line.
    According to the invention it can be provided that the front weight has a carrier for mounting the front weight on an agricultural machine, wherein the shield plate is arranged between the carrier and the sensor receiving area. This ensures that, when the front weight is correctly mounted, the shielding plate is located between the working machine and the transmitting and receiving coils.

The sensor shield can be removed in particular from the sensor receiving area. This allows the implementation of the device according to the invention as a modular system: The sensor components can be installed in the front weight and removed from it, so that a use of the sensor components without the front weight is possible.
    The width of the sensor receiving area or the sensor shield may correspond to the measure of the maximum transmitting and receiving coil configuration for receiving the sensor components, that is about 1681 mm.
    The sensor shield may comprise a metal or glass fiber reinforced plastic. The sensor shield may preferably be provided with a terminal to connect to an external electrical ground line.
    According to the invention, it can be provided that a preferably ultrasound-based distance sensor is provided for determining the distance of the device to the substrate. The distance sensor may preferably be provided in the lower region of the front weight.
    According to the invention, it can be provided, in particular, that the shielding plate is arranged between the sensor receiving region and the distance sensor. In contrast to the transmitting and receiving coils, the distance sensor is usually not affected by electromagnetic interference of the tractor, so that a shield is not required.
    According to the invention it can be provided that at least one inclination sensor is provided for determining the inclination of the device relative to the ground.
    According to the invention it can be provided that at least one localization module, preferably a GPS module, is provided.

    An arithmetic unit for converting the received signals into electrical conductivity values and soil parameters, for example density, moisture and soil type, can be provided on the work machine. Furthermore, control outputs for controlling external soil cultivation devices can be provided on the work machine. The control outputs may preferably be arranged in the rear region of the work machine, so that an immediate control of arranged in the rear of the machine tillage equipment based on the detected during a working ground condition is made possible.
    The invention further comprises a method for operating an agricultural machine according to the invention, wherein during a working drive of the machine the ground parameters of the currently to be processed ground section are detected.
    The device may preferably be moved during the working runs of the working machine at a speed of a maximum of 15 km / h over the surface to be examined, the detected nature of the ground, for example the soil type, is used directly for controlling mounted at the rear of the machine tillage equipment ,
