Abstract: A third-party interference monitoring system is provided. The third-party interference monitoring system, according to one embodiment of the present invention, is for detecting third-party interference in advance before a buried pipeline buried underground is damaged by the third-party interference. The third-party interference monitoring system comprises: a sensor unit which is installed on a buried pipeline so as to detect an impact signal which is propagated along the ground or the buried pipeline when heavy equipment strikes the ground; and a control unit which acquires a time domain value of the impact signal by receiving data from the sensor unit, converts the time domain value to a frequency domain value, and then detects the third-party interference on the basis of frequency response characteristics of the impact signal.

Abstract: The present application relates to a system, device, and method for monitoring an abnormal state of pipe, which monitors whether a pipe is abnormal. In the present application, a pipe state signal input from each signal acquisition part is divided into a plurality of time periods, and then it is determined whether an abnormal state signal exists in the pipe state signal in each of the time periods. Therefore, the present application enables determination with higher accuracy of whether the pipe is abnormal, compared to the case of determining whether an abnormal state signal exists in a pipe state signal which has not been divided into a plurality of time periods.
