Abstract

The invention discloses a beacon detection device, which includes a control processing unit, a weak signal processing unit and a power supply; the first input end of the weak signal processing unit receives an external sensor signal, and the second input end is connected to the first output end of the control processing unit , the power supply terminal is connected to the first output terminal of the power supply; the input interface of the control processing unit is connected to the output terminal of the weak signal processing unit, the first power supply terminal of the control processing unit is connected to the second output terminal of the power supply, and the second power supply terminal is connected to the second output terminal of the power supply Three output terminals; the second output terminal of the control processing unit is used as an interface with the external underwater acoustic communication equipment; the first input terminal, the second input terminal and the third input terminal of the power supply are connected to the first switch control signal corresponding to the control processing unit The output terminal, the second switch control signal output terminal and the third switch control signal output terminal; the device determines the transit time of the magnetic flux leakage detector by detecting the ultra-low frequency signal radiated by the magnetic flux leakage detector, and has the characteristics of low power consumption.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and more specifically relates to a beacon detection device. Background technique [0002] As one of the transportation industries, pipeline plays a very important role in the national economy. During the construction and operation of pipelines, due to various reasons, there will inevitably be risks such as dents, deformations, corrosions, perforations caused by external forces, and pipeline displacements. If these risks are allowed to occur, explosions, Leakage will cause immeasurable losses to people's lives and property and the ecological environment. [0003] The metal loss defects of pipelines include volume defects such as mechanical damage and corrosion. The main detection methods include magnetic flux leakage testing, ultrasonic testing, and eddy current testing; among them, ultrasonic testing and magnetic flux leakage testing are the most widely used. The magnetic flux leakage...
