Design and implementation of optical fiber transmission system for logging information
Aiming at the problems of poor anti-interference ability,low transmission rate and short transmission distance in traditional logging cable transmission,an FPGA-based optical fiber transmission system for logging information is designed.The system collects downhole video,temperature and pressure information and transmits it to the well through optical fiber link.With FPGA as the main controller combined with optical fiber link transmission system,the overall scheme design of downhole information optical fiber transmission system for multi-parameter measurement can be realized,and the system function test can be carried out.The results show that the communication and application functions of the optical fiber communication system are normal,and the feasibility and effectiveness of the optical fiber transmission system for logging information are verified.
