INSTALLATION OF AUTOMATIC MONITORING SCRAP METAL IN MOVING railway wagons

摘要

The utility model relates to systems for remote monitoring of the scrap metal in moving railway carriages, namely the system determine the degree of contamination nonmagnetic materials by measuring the ferromagnetic mass of the load ( "magnetic" mass) and comparing it with the data of the scale car. The basis of the utility model is to provide an automatic monitoring installation metal in moving railway vehicles comprising a measuring frame for generating a magnetic field, the power supply unit, a data processing unit of the automatic analysis and detection. The measuring frame is formed as two identical planar crossed coils oriented with their planes mutually perpendicular to each other and arranged as to pass through them wagons. Thus the magnetizing currents in the coils can be set different in amplitude, frequency and phase or equal amplitude and frequency but shifted in phase by 90 °, thereby providing a magnetic field rotating in the horizontal plane beyond the measurement zone. This reduces the error in the measurement of the mass of scrap metal by taking into account its degree of anisotropy and determine the grade scrap. N.p.f. 1, 2 z.p.f. 5 Fig.
