Development of Anomaly Monitoring System for Pipes with Recognition of Anomalous Object

对于生命线和各种工业装置的维护来说，对管道系统的异常监测是非常重要的。管道系统中的各种监视器被简化为管道的识别和管道长度的测量。在本项目中，开发了利用管道系统中产生的驻波来实现这一目标的有效方法。声学传感器用于构建这些系统。为了对管道系统中的异常物体进行识别，不仅开发了测量系统，而且开发了基于脉冲回波法的传感方法。

For maintenance of life lines and various industrial plants, it is important to monitor the anomaly of pipe systems. Various monitors in pipe systems are reduced to the recognition of the pipe and the measurement of the pipe lengths. In the project, powerful methods using stationary waves generating in the pipe systems are developed to realize the objective. An acoustic sensor is used to construct those systems. Not only the measurement systems, but also the sensing method based on pulse-echo method is developed to recognize the anomalous objects in the pipe systems.
