Abstract

The invention discloses to a small leakage detection ball for a liquid pipeline and relates to the technical fields of tests not included in other classes, acoustic wave measurement and pipeline systems. The small leakage detection ball for the liquid pipeline comprises a battery and power supply switching circuit, an electret microphone and a signal processing circuit, an STM32 (scanning tunneling microscope 32) processor, an inertial navigation module, a timing unit, a magnetic field transmitting device, an SD (secure digital) card memorizer, a USB (universal serial bus) interface and a Jtag (joint test action group) interface of the electret microphone, wherein an output end of the electret microphone is connected with the signal processing circuit which is connected with the STM32 processor, the STM32 processor is connected with the inertial navigation module, the timing unit, the magnetic field transmitting device, the SD card memorizer, the USB interface and the Jtag interface, and the battery and power supply switching circuit is connected with all the circuits to supply power to the same. The small leakage detection ball for the liquid pipeline can detect small and even tiny leakages and is high in sensitivity.

Description

technical field [0001] The invention is a small leakage detection ball of a liquid pipeline. It relates to the technical fields of testing, sound wave measurement and piping systems not covered by other classes. technical background [0002] With the continuous development of the pipeline transportation industry, the increase of pipelines, the extension of pipeline laying distance, the increase of pipeline service period, and the unavoidable factors such as aging and corrosion of equipment, operational wear and geography, climate and environment changes and man-made damage, once leakage will not only Cause huge economic losses, and will cause environmental pollution, casualties and so on. Therefore, accurate detection and accurate location of pipeline leakage are of great practical significance to improve the management level of pipeline transportation and reduce economic losses and environmental pollution. [0003] At present, there are many pipeline leakage detection tec...

AI Technical Summary

Problems solved by technology

[0005] Although these technologies all claim to be able to solve the problem of leak detection of liquid pipelines, since pipelines are large-scale linear underground structures, objective factors such as liquid properties and geographical environment along the way greatly affect the stability and reliability of various systems. and have a direct impact on detection sensitivity and practicality

Therefore, the existing real-time leak monitoring technology has a significant effect on the detection of large leaks, but it cannot detect small leaks; the existing non-real-time detection has a large workload and is difficult to implement for buried pipelines
