摘要： A method for detecting an electrically and/or magnetically conductive object in a vicinity of a sensor head of a device, having the following steps: emitting a transmitting signal into the surroundings, receiving a received signal as a function of the transmitting signal and the characteristics of the object and the surroundings, analyzing a response signal formed from the received signal. According to the invention, the detection is controlled by providing a class system having a number of classes, which differ from one another in at least one object and/or surroundings characteristic, and classifying instantaneous object and/or surroundings characteristics as a function of the analyzed response signal in a class of the class system, and predefining detection characteristics which are preset in the classified class, a further response signal being detected using the predefined detection characteristics.

摘要： A method for the detection of objects embedded in building structure subgrades such as cable, concrete reinforcing bars, conduit pipe and the like as well as a hand-operated sensor with an adaptive detection threshold operating according to the method, is disclosed. To reduce an over-detection with the adaptation of the detection threshold, a change in the direction of movement of the sensor being guided over the surface area is recorded with respect to an embedded object. The determination of a change in the direction of movement preferably takes place by measuring the sensor acceleration in two directions with respect to the embedded object. Corresponding speeds are computed at least as estimates from the acceleration values in order to generate a conclusion about a reversal of the direction of movement.

摘要： A coil arrangement for a magnetic sensor for detecting metallic objects in a subgrade, in particular structures made of concrete, brick, and wood, as well as a method for energizing and reading out this coil arrangement, is disclosed. The coil arrangement includes one or preferably two stacked outer main coils via which a perpendicular magnetomotive force of the subgrade is effected. Provided within the outer main coil(s) is, on the one hand, a quartet of a total of two pairs of parallel coils lying symmetrical to the axis of the main coil(s), via which a magnetomotive force penetration of the subgrade in two directions parallel to the subgrade surface is possible. To further improve the accuracy and reliability of localizing objects and estimating depth of cover, two pairs of smaller orthogonal coils each opposite from one another and also arranged symmetrically to the axis of the main coil(s) are provided.
