Cx The invention relates to automata (computer and computer technology, in particular, to devices for reading information from moving objects in railway transport. Purpose of the invention is to increase the quality of the device. The drawing shows a basic diagram of a device for reading information from Moving objects. The device contains a block 1 of magnetically sensitive elements in the form of a matrix containing informational elements 2; located in pairs, control elements 3 located along the edges of the matrix, all of which The matrix cells are permanent bar magnets 4, and each cell of the matrix, reflecting one bit of information, is formed by two magnets with mutually opposite orientation of the magnetic poles, the measuring transducer 5 in the form of a matrix of informational fluxes 6 arranged in pairs, and controlled flux probes 7 and 8 located along the edges of the matrix, the exciter windings of all the flux probes are connected according to the Compound current circuit and powered from generator 9, and the output measuring windings of each pair of flux zones A sequence-counter, signal processing unit 10, consisting of a polarity II discriminator and a remote processor 12, the output of which is the output of the device, is included. The device works in the following way. When block 1 of magnetically sensitive elements is combined with a measuring transducer 5, as a result of moving a moving object, the read signals from control 7 and 8 and information 6 flux probes are sent to the discriminator of polarity 1 and further to the output of the device. The sequence of interaction of the magnets 4 with control fluxes 7 and 8 is determined by the direction of movement under the moving object. The moment of reading information is determined by signal 1 from one magnet and signal O 02 from another magnet. The reading of information from each pair of information elements 2 is carried out by a corresponding pair of information flux-probes 6 placed coaxially with the information magnets. The output measuring windings of each pair of flux-probes are connected in series at a stroke, so that the flux-probes are plugged in for the signal being read. in phase, and for interference - antiphase. When a pair of permanent magnets with a combination of an NS or SN field is located over each pair of flux-probes, the electrical signals, respectively, of positive or negative polarity in the output windings of each pair of ferroxons are summed. When exposed to the same pair of flux-probes of an external magnetic field, the generated electrical signals in the output windings of this pair of flux-gates are compensated. The invention is a device for reading information from moving objects, containing a block of magnetically sensitive elements in the form of a matrix, each cell of which contains one constant n-. rod magnet, a measuring magnetically associated measuring transducer in the form of a matrix, each cell of which is made in the form of two flux-probes, and a signal processing unit, the output of which is the output of the device, which differs from The cell of the matrix of a magnetically sensitive element 6V contains additionally a second CONSTANT bar magnet with mutually opposite orientation of the magnetic poles with respect to the first magnet, and the outputs of the fluxglobes of each cell Itza transducer posledovatelnovstrechno interconnected and connected to the respective inputs of the signal processing unit.
