Pipeline leakage detection device and leakage detection procedure (CAP)

摘要

The device of the invention appears in a small neutral floating control area, wherein at least one hydrophone (2) is connected with a signal processor (9),Save the information on the memory card (10) and have at least one battery (11),Including such a signal processor (9) and a clock module (12),Connect the navigation time (2) of each audio signal received by the hydrophone to the memory (10),Therefore, the exact location of the detected anomaly or leakage can be determined according to the sailing time. The device is supplemented by a series of external synchronizers, which are fixed once for each distance, so as to eliminate the possible accumulated position errors of the device. This provides a simple, low-cost, robust, durable and extremely efficient device.
