AUTOMATIC LOCKING MIRCOPROCESSOR-BASED DEVICE Russian patent published in 2009 - IPC B61L23/16 B61L27/04 

FIELD: railway transport.

SUBSTANCE: invention relates railway automatics and telemetry hardware and can be used to ensure safety and control of traffic on station limits, high-speed and main lines, as well as on low-activity railroads equipped with DC or AC traction motors or self-contained traction systems. It can also be used at blocks with centralised electrical supply of passengers' cars, blocks of locomotives and rolling stock interchange. The proposed device comprises PC-based railway station operator post (RSP), modem for communication with adjacent railroad station, radio channel aerials and aerial-feeder device for radio modem and radio modem to transmit digital data over the radio channel. The device generates control signals at the RSP to initiate inhibiting light at whatever light signal, that at the nearest track light signals on cutting in obstruction lights, to initiate unlocking the inhibiting signals, cut in earlier or locked due to faulty algorithm of the automatic locking system operation. It also generates information for SPS about current state of the objects under control and the system faults, if any.

EFFECT: expanded performances of microprocessor-based automatic locking system.
