FIELD: transport.
SUBSTANCE: this system comprises interconnected stationary centres of radio block system connected to computer of the dispatcher control centre and to railway haul base stations via communication circuit. At spans between adjacent stations these are connected via fibre-optic cable and radio channel of the train onboard hardware. The latter comprises complex locomotive safety device, locomotive location determination unit, allowable speed, braking curve and data exchange calculation unit interconnected via locomotive onboard digital data exchange system interface, eddy current device for actual control over current conditions of the rails and refined speed measurement, and engineman display. Fibre-optics cable is composed of combined sensor and communication cable. Said cable is laid at span along the track to allow the transfer of external forced from track structural components to cable outer shell and includes inner elements of mechanical connection between cable shell and sensor optical fibres with variable optical parameters at their deformation. Note here that said optical fibres are connected by one end with first communication ports of span units for generation and analysis of impulse light signals. Second communication ports are connected to communication ports at video observation floor units. The latter incorporate the unit of train end video signal automatic registration. Their opposite ends are connected with appropriate fist ports of stationary unit for generation and analysis of impulse light signals. Second communication port of the latter is connected via data transfer circuit with computer of the dispatcher control centre.
EFFECT: higher reliability and safety.
