Deteksi Kerusakan Pipa Dalam Bentuk Kebocoran Dan Sumbatan Menggunakan Sinyal Suara Dan Dual Mikrofon
The piping system is an important feature in the industrial world, because it has an
effective and efficient transportation function used for shipping such as liquid and
gas fluids. Prevention of damage either leakage or blockage is very important
because it can reduce the number of losses both economic, natural environment,
and even loss of life. This study a method was developed to detect damage in pipe
using sound signal. This method can be used because it is very sensitive to
discontinuities in the pipe that can detect damage at a relatively lower cost. This
method uses sound impulses emitted through the loudspeaker as excitation and the
response of the sound signal will be recorded using a dual microphone sensor.
Sound signals are given for leakage, blockage and joint damage under conditions
of using water and without water of different sizes, positions and polar sides. The
sound signal data will be processed using the Fast Fourier Transform and Wavelet
Transform methods. The test results show that the amount of damage given is
directly proportional to the amplitude generated and the wavelet coefficient of each
microphone sensor will increase as it approaches the polar side of the damage. The
conclusion is that this is an effective method for detection of leaks and blockages
that occur in pipes.
