The invention discloses a communication positioning device and method applied to a pipe cleaner inside a benthal oil pipeline. The communication positioning device and method are characterized in that at the seabed part of an oil conveying double-layer pipeline, the pipe cleaner is arranged in an inner pipe, and an emitter is arranged on the pipe cleaner and used for emitting signals; one end of a communication device in a seabed pipe is connected with the outer wall of the inner pipe, and the other end of the communication device is connected with the inner wall of an outer pipe; at the land part of the oil conveying double-layer pipeline, the inner pipe is connected with the positive electrode of a land power source and the positive electrode of a land circuit board power source, the outer pipe is connected with a land monitoring device, and the land monitoring device is further connected with an upper computer used for monitoring. The communication positioning device and method resolve the problems that seabed communication power supply in the prior art is difficult in construction, high in manufacturing cost and highly risky. Through the structure and method, the novel seabed power supply and communication method is provided while detection accuracy is guaranteed, the manufacturing cost is reduced, application risks are reduced, and the safety and stability of the whole device are improved.
Description
technical field [0001] The invention relates to a communication positioning device and method, in particular to a communication positioning device and method applied to pigs in submarine oil pipelines. Background technique [0002] After the installation and operation of the offshore oil pipeline, the inside of the pipeline must be cleaned to remove debris in the pipeline or sediment on the inner wall. Cleaning the pipeline is an important measure to ensure the smooth flow of the pipeline. Since the pig is operated in the pipeline , the pig will inevitably be stuck by the pipeline, and at this time it is necessary to find the stuck position. However, the problem of power supply and communication under water is difficult to solve. The sea water attenuates the signal too much, and it is impossible to do wireless communication on the seabed. It is also affected by sea waves and fishing boats. The floating platform sampling technology cannot be fixed, easily damaged, and operate...
