Automatic identification of oil sucker pipe using character coding

Abstract

As there is lack of valid marking of oil sucker pipe, some pipes which exceeding time limits may break off. The character coding method is presented, soft touch flexible marking technology is used to marking characters on pipe, characters can hold for a long time in erosive environment. Each pipe has each code using character coding method. Pipe is automatically identified using CCD and image processing technology, the pipe which exceeding time limits can be identified in time. The dynamic management can be achieved for a single pipe from use, maintenance to abandon using database system.
