DEVICE FOR DETERMINING SPACE POSITION OF RAIL TRACK Russian patent published in 1995 - IPC

FIELD: road building. SUBSTANCE: device has odometer 5, gyroscope course transmitter 2, gyroscope tilting transmitter 3 in course, outputs of transmitters being connected to recorder unit 14. All these transmitters are installed on flat car 1 moving along the rail track. Device has gyroscope transmitter 4 checking tilting of track in cross plane, rail-to-rail distance transmitter 6 and submersion transmitter 7; outputs of these transmitters are connected with analog signal switch 8 for connecting outputs of each transmitter in turn to input of analog-to-digital converter 9 which converts transmitter voltage signals into parallel code; outputs of analog-to-digital converter 9 are connected to inputs of digital signal switch 10 whose output is connected by communication line 15 with computer unit 13 to supply sequential code signals to its input; output of unit 13 is connected to recorder unit 14. Control inputs of analog signal switch 8 and digital signal switch 10 are connected, respectively, to outputs of higher-order and lower-order stages of counter 11 whose input is connected with output of clock pulse generator 12. EFFECT: enlarged operating capabilities. 4 dwg
