Abstract:  In view of the increasing construction of pipeline, a position system based on the Beidou system was proposed. The Beidou navigation positioning system can accurately obtain the location of the working pipelayer’s information, thus, to locating single pipe. Likely, a pipeline crawler with Beidou position module can be placed in the pipe, a pipeline diagram can be formed through getting position continuously. Not only save the manpower cost, but also monitor the pipeline laying. Some necessary and emergency things can be solved combine with other instruments, provides value reference for the optimization of pipeline construction and management.
