Signal analysis system and signal analysis method for large-capacity rapid storage and playback

Abstract

The invention discloses a signal analysis system and a signal analysis method for large-capacity rapid storage and playback, which belong to the field of signal analysis. The signal analysis system comprises a host central processor module, a data acquisition module, a data processing module, a storage and playback control module and a plurality of recording hard disks. After broadband medium-frequency signals enter the data acquisition module for analog-to-digital conversion, the data processing module carries out digital mixing and decimation filtering on the signals, the signals then enter the storage and playback control module, and under the control of the storage and playback control module, data are directly outputted to the host central processor module, or are stored into the recording hard disks. While analyzing signals, the signal analysis system and the signal analysis method for large-capacity rapid storage and playback disclosed by the invention continuously store high-speed sample data into the hard disks without loss, and can implement the playback and analysis of the data, and not only can sudden and transient signals be conveniently recorded, but also the recorded signals can be analyzed in depth, so that more valuable information can be mined.

Description

technical field [0001] The invention belongs to the field of signal analysis, in particular to a signal analysis device and method for large-capacity fast storage and playback. Background technique [0002] With the development of information technology, the electromagnetic environment has become more and more complex, and it is becoming more and more difficult to capture and analyze signals. The amount of signal data required to capture signals is also increasing, and real-time analysis is difficult for many The multi-parameter and multi-angle analysis of the evanescent signal can easily lead to the loss of information. Traditional signal storage is realized by reading the sampled or processed data through the CPU module, and then writing them into the hard disk connected to the CPU module. The data has been dumped many times, and subject to the slow speed of the CPU shared bus and the relatively large amount of data, it is impossible to achieve high-speed storage of origi...

AI Technical Summary

Problems solved by technology

The data has been dumped many times, and due to the slow speed of the CPU shared bus and the relatively large amount of data, it is impossible to achieve high-speed storage of original data without loss, continuous high-speed storage of sampled data, and high-speed playback. It can only realize intermittent storage, that is, store part and lose part, which cannot meet the real-time monitoring and recording of signals
