Method and system for detecting defects in pipes or other structures |
摘要 |
A method and system for rapidly connecting and rapidly disconnecting a large number of point contacts onto a pipe surface for detecting defects in pipe and other structures is taught. The method and system involve independently pressing a plurality of sharply pointed pin contacts onto the pipe surface by a means, such as a spring. The system comprises a plurality of electrodes each having a plurality of pins, as illustrated seventeen (17) pins, arranged in a pattern. Each of the plurality of pins is held in a conforming opening in the electrode and is urged by springs means, such as a coil spring, against the surface of the structures. Each of the plurality of pins (sixteen (16) current pins and one voltage pin) are individually connected to a power supply and sensing apparatus. This system and method has proved operable for detecting defects in structures, such as pipe.
