| Abstract: | This paper describes an acoustic potential survey system for cathodic protection of submarine pipeline which is set up by utilising acoustic telemetering technique. The structure principle and design of the system are introduced emphatically. The system comprises of a surface display unit and submarine monitors. The PPM-PTC (Pulse Phase Modulation-Pulse Time Code) pattern is adopted to transmit the submarine data. The advantage is that the strong noise and serious undulation of sound signal in the sea could be overcome. Each submarine monitor contains dual reference comprising of both Ag/AgC1 and Zn alloy. This system can be used to make remote, flexible and reliable potential measurements. The system-is also simple in structure, interference resistant and accurrate. |
