OPTOELECTRONIC SYSTEM TO CONTROL SPATIAL POSITION OF RAILWAY TRACK

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to control instruments. Proposed system comprises radiation source 2 and signal processor 3 and photo receiver 1 made up of level transducer 21 and receiving analyser system 11 including lens 13 and position-sensitive optical radiation receiver 15, arranged on control truck 9 arranged on track 10. Output of photo receiver 1 is connected to input of signal processor 3. Radiation source is arranged on at least one contact-wire line support 4 or other structure, and is made up of reference mark containing at least two modulated light diodes 5 and photo receiver (b) and radiation source control circuit connected to independent power supply input 7. Photo receiver unit comprises extra receive-and-analyse system 12, control module 17 including at least one light diode radiator 18, photo receiver 18 and data signal processing circuit 20 with its output connected with input of second processing unit 3 with third input connected to level transducer 21 rigidly coupled with photo receiver 1. ^ EFFECT: higher accuracy of measurement. ^ 2 dwg
