Pipe network audio collector and realization method

The invention relates to a pipe network audio collector and a realization method. A pipeline audio collector consists of a processing unit, a front end audio pickup unit, a frequency discrimination and triggering unit and a power supply unit, wherein the processing unit adopts a Haisi processor chip Hi3520, the front end audio pickup unit consists of a casing, a sound pickup head and a diaphragm, the top of an inner cavity of the casing is fixedly provided with the sound pickup head, the diaphragm is fixedly arranged at the top of the inner cavity, a sound pickup head lead is led out from the top, and the frequency discrimination and triggering unit consists of an outer casing, a base, a pressure sensitive element, a mass block and a spring. Voltage signals generated by sound at the frequency sent when normal water flow flows through a pipeline are collected by the pipe network audio collector, the voltage signals are stored in a memory to be used as standard voltage data, the real-time voltage data collected in each time is compared with the standard voltage data, and whether the voltage data is normal or not is judged through comparison, so whether the pipeline is damaged or not is judged. Compared with the manual recognition, the pipe network audio collector has the advantages that the detection accuracy rate is high, personnel are reduced, the effect is better, and the economic effects are obvious.
