AUTOMATED SYSTEM FOR FREIGHT TRAIN DRIVING ACCORDING TO REAL-TIME RUNNING SCHEDULE Russian patent published in 2015 - IPC B61L25/02 

FIELD: transport.

SUBSTANCE: system includes computing unit with memory unit, train movement parameter measuring facilities and indication facilities connected to it, as well as with traction mode control unit and braking mode control unit the outputs of which are connected with train control circuits, armature current and traction motors excitation sensors, overhead system voltage sensor, three units of high-voltage galvanic isolation, computing unit, train dynamical characteristics simulation unit, comparison unit and traction and braking modes control inhibition instructions generation unit. Traction motor armature current sensor output is connected via the first high-voltage galvanic isolation unit with the first input of computing unit, with the second input of which the traction motors excitation sensor output is connected via the second high-voltage galvanic isolation unit. The overhead system voltage sensor is connected via the third high-voltage galvanic isolation unit with the third input of computing unit the output of which is connected to the first input of train dynamical characteristics simulation unit to the second input of which the memory unit output is connected. The output of train dynamical characteristics simulation unit is connected with the input of comparison unit, to the second input of which signal generation unit is connected which signal corresponds to maximum allowable force in the train, comparison unit output is connected with output of traction and braking modes control inhibition instructions generation unit the output of which is connected to corresponding control inputs of traction mode control unit and braking mode control unit. Additionally, train movement real-time schedule data acquisition unit is introduced which unit is associated with cellular communication signal receiving facilities and connected to memory unit.

EFFECT: automatic updating of specific train schedule in real-time mode.
