This paper introduces the opto - mechatronic design of large radio telescope. According to the geographic location of KARST landform in Guizhou, the scanning trajectory of line feed is deduced. The solution of cable deflection and cable tension is obtained by catenary equation. The kinematic description and analysis of the cable-parallel cable structure are put forward, and the solution to the real-time problem of the cable length control is proposed. Finally, the calculation formula of the end coordinate of the cable at dynamic detection
