A signal analysis device and method for large-capacity fast storage playback

Abstract

The invention discloses a large-capacity fast storage and playback signal analysis device and method, belonging to the field of signal analysis, including a host CPU module, a data acquisition module, a data processing module, a storage and playback control module, and several recording hard disks, broadband intermediate frequency signals After entering the data acquisition module for analog-to-digital conversion, the signal is digitally mixed and extracted and filtered by the data processing module, and then enters the storage and playback control module, and the data is directly output to the host CPU module through the storage and playback control module, or the data is saved. In several recording hard disks. The present invention is a large-capacity fast storage and playback signal analysis device and method. While analyzing the signal, the high-speed sampling data is continuously stored on the hard disk without loss, and the playback analysis of the data can be realized, which is convenient for recording sudden transients. signals, and can also conduct in-depth analysis on the recorded signals to discover more valuable information.

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
