Abstract
The synchronization-free pipeline leak detection system includes a plurality of acoustic sensor nodes positioned equidistantly and linearly against an external surface of a wall of a pipeline. Each of the acoustic sensor nodes receives an acoustic signal generated by a leak in the wall of the pipeline, which is transmitted through fluid flowing through the pipeline. Each of the acoustic sensor nodes measures an acoustic received signal strength associated with the acoustic signal and transmits a signal representative of the respective acoustic received signal strength to the immediately adjacent acoustic sensor nodes if the respective acoustic received signal strength is greater than a threshold signal strength value. From the transmitted acoustic received signal strengths between sensor nodes, the sensor node closest to the leak can be determined. From known values stored in each sensor node, the position of the leak can be calculated and transmitted in an alert signal.
