A system for sensing abnormality of a pipe protecting an underground cable is provided to safely and effectively keep and manage distribution lines separately by including a cover to selectively open an inside. A system for sensing abnormality of a pipe protecting an underground cable includes a sensing unit(200) and a management unit(300). The pipe includes a housing, a support net, and a cover. The sensing unit checks an opening and closing state of the cover and includes first and second piezoelectric elements(210,220). The management unit checks a state of the pipe by receiving a signal transmitted from the sensing unit and includes a receiving unit(310), a checking device(320), and an alarm unit(330). |
