DEVICE FOR READING INFORMATION FROM MOBILE OBJECTS OF RAILWAY TRAINS Russian patent published in 2020 - IPC B61L25/02 

FIELD: rail vehicles.

SUBSTANCE: invention relates to means of obtaining information from mobile objects of railway transport. Technical solution includes a reading device, a control station and an on-board part, comprising passive code sensors installed on the containers with possibility of reprogramming the code signal, and on opening parts of containers - passive transponders of identification of object with constant code, on platform and each wheel pair of car passive transponders of identification of object with constant code are also installed. At that, receiver of dispatcher station is equipped with amplifier of total frequency, mixer, amplitude detector, key, third and fourth multipliers, second low-pass filter, second narrow-band filter, subtraction unit and two phase inverters, wherein to the output of the mixer there is connected in series the amplifier of the sum frequency, the amplitude detector and the key, the second input of which is connected to the output of the intermediate frequency amplifier, and the output is connected to the second inputs of the first and second multipliers, the third multiplier, the second narrowband filter, the first phase inverter, the fourth multiplier whose second input is connected to the key output, the second low pass filter and the second phase inverter are connected in series to the key output, output of which is connected to the second input of the third multiplier, outputs of the first and second low-pass filters through the subtracting unit are connected to the input of the computer.

EFFECT: higher noise immunity of the control room receiver is achieved.
