Pipeline detection system with functions of multi-frequency switching and multichannel parallel excitation and collection

Abstract

The invention provides a pipeline detection system with functions of multi-frequency switching and multichannel parallel excitation and collection. The system comprises a sensor module, a channel selection switch, a signal processing module, a data storage module, a MCU controller, a frequency generation module and a communication module, wherein the sensor module is connected with the channel selection switch; the channel selection switch is connected with the signal processing module; the signal processing module is connected with the data storage module; the data storage module is connectedwith the MCU controller; the MCU controller is connected with the frequency generator and the communication module; and the communication module is connected with a PC. The pipeline detection systemcan freely select required excitation frequency to adapt to different types of pipelines and defects, has smooth and stable output signals under different frequencies without distortion, supports multichannel parallel excitation and collection along with synchronous performance of excitation and collection and high detection efficiency.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to a pipeline detection system with multi-frequency switching and multi-channel parallel excitation and acquisition. Background technique [0002] Pipeline transportation systems are widely used in industrial sectors such as petroleum, chemical industry, natural gas, tap water and electric power, and play a huge role in national economic and social development. Due to the long-term scour and corrosion of the transported goods and human damage, the pipeline often has defects such as cracks, oxidation, and thinning of the wall pipe, which seriously threaten the lives and property safety of the people. The traditional ultrasonic testing technology must scan point by point when testing pipelines, which is slow and inefficient, and most of them use computers, function generators, power amplifiers, oscilloscopes, sensors, etc. in combination, facing complex operations, complicated wiring...
