DEVICE FOR RECORDING TRAIN MOVEMENT PARAMETERS Russian patent published in 1995 - IPC

FIELD: railway transport. SUBSTANCE: device has track and speed pickup 1, time mark pickup 2, brake main line pressure pickup 3. Output of track and speed pickup 1 is connected to inputs of unit 4 determining covered distance and unit 5 determining speed. Second input of speed unit 5 is connected with output of time mark pickup 2, input of unit 6 determining current time and input of AND gate 7; second input of AND gate 7 is connected with output of manual control setting element 8 and output of threshold element 9; output of AND gate 7 is connected with input of OR gate 10 whose second input is connected with output of covered distance unit 4 and output, with control input of recorder 11. Information inputs of recorder 11 are connected with outputs of pressure pickup 3, current time unit 6 and speed unit 5. Output of unit 5 is coupled also with input of threshold element 9. EFFECT: enlarged operating capabilities. 1 dwg
