SYSTEM TO CONTROL OPERATION OF RAILWAY COLOUR SIGNAL LIGHTS Russian patent published in 2011 - IPC B61L29/22 B61L27/00 

FIELD: transport.

SUBSTANCE: invention relates to railway ACS ad telemetry systems and may be used to detect unauthorised initiation of signal light or its faulty operation. Proposed system comprises computer-aided workstation of train dispatcher or station supervisor (TD or SS), control unit, actuator that includes train route input device and train route execution device. Outputs of said units are connected to TD or SS board. Outputs of train route execution device are connected to signal light control hardware while control output of TD or SS device is connected to train route input device input. Control unit comprises signal light interrogation unit, decoder, control unit, time selector, inverter and signal light state determination unit. Signal light interrogation unit, decoder, control unit, tie selector and inverter are connected in series. First, second and third control inputs of signal light state determination unit are connected to outputs of decoder, time selector and inverter, respectively. One outputs of signal light state determination unit are connected to train route execution unit inputs while its other outputs are connected to TD or SS board inputs. Inputs of interrogation unit are connected to signal light control hardware. TD or SS device is connected via communication channel with hardware and software of communication and signaling service dispatcher workstation.

EFFECT: higher reliability of signal light operation.
