SYSTEM FOR LOCOMOTIVE MOVEMENT CONTROL DURING SHUNTING OPERATIONS Russian patent published in 2011 - IPC B61L3/20 

FIELD: transport.

SUBSTANCE: invention relates to railway automatic control and telemetry systems and can be used in locomotive movement control systems. The system contains traffic lights (1, 2) and track circuits (3-5), track circuit encoding and control unit (6), electric interlocking tower hardware unit (7) and automatic locomotive signaling unit (8), locomotive coils (9), indicating unit (10), program speed calculation unit (11), path and speed transducer (12), speed metre (13), acceleration measurement unit (14), comparator (15), brakes and traction control unit (16), traction motors controller (17), navigation satellite system and electronic map unit (18), car location unit (19), the first (20) and the second (21) limit switch of locomotive automatic couplings, memory unit (22), stop determination unit (23). Automatic locomotive signaling unit (8) and electric interlocking tower hardware unit (7) are interconnected via their antennas (24, 25) by means of radio channel of digital communication. Electric interlocking tower hardware unit (7) is connected with computer of automated workstation of shunting operations dispatcher (27). This computer's memory unit (28) contains database with information about groups of detached cars standing within the station. Electric interlocking tower hardware unit (7) is equipped with unit for acceleration of automatic discoupling of the last route sections (29), and the second output of automatic locomotive signaling unit (8) is connected to the control input of showing the shunting route last section on the indicating unit (10) display.

EFFECT: higher system efficiency while keeping required level of functional safety.
