AUTOMATIC BLOCKING DEVICE Russian patent published in 2008 - IPC B61L23/16 

FIELD: transport.

SUBSTANCE: device containing two microprocessor controllers (K) each of which contains two ports of serial interface, address port, parallel information input port, and information input/output port. There are pattern of code signal choice, demultiplexer, and multiplexer. Second port series transmission output for data of the first K via generator including modem with angle modulation and path amplifier, is connected to demultiplexer information input. Demultiplexer address inputs are connected to first K address port, and its outputs - to respective cable line and via matching element to feeding end of rail circuit. Input end of rail circuit via respective matching device and cable line is connected to respective multiplexer information input. Multiplexer output is connected to input of receiver including filter, angle modulation demodulator, and analog-to-digital converter. Filter output is connected to demodulator and analog-to-digital converter inputs. Demodulator output is connected to second port series transmission of second K data. Analog-to-digital converter outputs are connected to parallel information input port of same K. Multiplexer address inputs are connected to address port of second K. Outputs of pattern of code signal choice are connected to cable line, and its first and second inputs are connected respectively to rail way route locomotive automatic signal devices and information input/output port of the first K. Linear circuits connecting fixtures of two stations are connected to information input/output port of the second K. Parallel information input port of first K is connected to all-electric interlocking circuits. First and second K are interconnected via first ports of serial interface.

EFFECT: increase of train traffic safety, broadening of functional capabilities, decrease of dimensions and power consumption.
