  • Publication number: 20230366516
    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.
