FIELD: determining the position of moving vehicle relative to fixed detection and ranging marker. SUBSTANCE: the device uses a coil, which, when energized, radiates a magnetic field consisting of magnetic lines of force coming radially and arch-like from the ends of its longitudinal axis. The sensor unit installed on the moving vehicle has four similar sensor (readout) coils, each having the main axis and being capable of perceiving the frequency of the marker magnetic field. These sensor coils are installed in two pairs, the main axes of the sensor coils of each pair are arranged on one of the two sides of the common central plane and run in parallel with it, the mentioned common central plane stretches in lateral direction relative to the marker coil longitudinal axis. Each pair of sensor coils is installed in an X-shaped manner in such a way that the main axes of the pair of coils intersect each other perpendicularly in the middle of their length and form the center of the pair of coils. Two pairs of coils are installed in such a way that their centers are shifted relative to each other by a fixed distance along the base line, which is intersected by the main axes at an angle of 45 deg. The sensor coils position signals are subjected to processing to obtain the values of the X-ray Y-coordinates, which indicate the relative positions of the sensor unit and marker. The marker can be excited inductively from the antenna on the moving vehicle. EFFECT: enhanced accuracy. |
