Abstract

This document describes the design, development and testing of an equipment for the detection of faults in oil pipelines. In the design phase, an exhaustive analysis of the technologies available for fault detection was carried out considering the acoustic emission method for the conception of the equipment. During the development phase, a power supply and signal conditioning circuit for the acoustic emission sensor was surveyed and built. The signal conditioning circuit has the function of adapting the acoustic signal in such a way that it is readable and processable by a microcontroller. Once the signal conditioning circuit has been completed, a graphic interface has been developed that shows the waveform of the signals captured by the equipment. This interface has a history that allows the user to have a quantitative reference of the different acoustic signals produced in the pipeline. The equipment has a built-in bluetooth module that establishes its communication with a computer using the USART communication protocol. Thanks to this configuration, the signals obtained by the sensor will be displayed in real time from a computer. Finally, tests were carried out with the equipment in a controlled environment where failure situations such as intermittent blows and continuous disturbances were generated. In this way it was possible to evaluate the ability of the equipment to capture the acoustic signals caused by any disturbance in an oil pipeline.
