Abstract

The invention discloses a high-frequency signal acquisition and data storage processing system and method. The system comprises a computer case as well as an ox horn terminal interface, an acquisition board, a main board, a 3G network card, a hard disk and a battery arranged in the computer case, wherein the ox horn terminal interface is connected with the acquisition board through a data line; the acquisition board is connected with the main board; the main board is connected with the 3G network card and the hard disk; the battery is used for providing a 12 V stabilized voltage supply for the main board through a voltage stabilizer. The high-frequency signal acquisition and data storage processing system collects high-frequency data of more than 100 Hz, stores mass data on the hard disk and realizes the transmission function through a 3G network.

Description

technical field [0001] The invention relates to the field of stray current monitoring of buried pipelines, in particular to a system and method for high-frequency signal collection and data storage and processing. Background technique [0002] The existing stray current monitoring system of buried pipeline includes hardware part and software part. The hardware part includes data acquisition instrument, field server and central server. The software part includes data transmission software and diagnostic analysis software, in which data transmission software generally includes functions such as data acquisition, data storage, and data upload. Diagnosis and analysis software can realize functions such as real-time display, time-frequency analysis, and limit value alarm according to needs. The current stray current monitoring system cannot achieve high-frequency acquisition of data above 100HZ, which causes some problems: [0003] 1. It does not have the ability to distinguis...
