CODE ONBOARD IDENTIFICATION SENSOR FOR AUTOMATED SYSTEMS OF RETRIEVING INFORMATION FROM RAILWAY VEHICLES Russian patent published in 2009 - IPC B61L25/02 G01S13/74 

FIELD: transportation; information technology.

SUBSTANCE: code onboard identification sensor is designed for use in railway transport, in systems of retrieving information from railway vehicles for identifying mobile vehicles and automated counting of railway freight traffic. The code onboard sensor has a transceiver antenna (1), which, through a matching transformer, is connected to the input of rectifier (3) for doubling output voltage, the output of which is directly connected to the first serial input/output of microcontroller (12). The microcontroller (12) comprises a non-volatile memory unit (15) containing an identification code of mobile units and codes for the state of main units and loads of the mobile units. The fourth serial input/output of the microcontroller is connected to a capacitor for period switching of the microcontroller (12). The microcontroller (12) is controlled by control module (14), with control program memory, stored in microcontroller (12). Transceiver antenna (1) can be stripped in form of a half wave linear oscillator. A quarter-wavelength balun can be used as the matching transformer (2).

EFFECT: increased accuracy and efficiency of controlling movement of railway vehicles and freight traffic.
