Method and device for realizing asynchronous signal sampling based on FPGA, electronic equipment and readable storage medium

Abstract

The invention provides a method and device for realizing asynchronous signal sampling based on an FPGA, electronic equipment and a readable storage medium. The method comprises the steps: receiving asampling signal, wherein the frequency of the sampling signal is set to be N times of a target frequency; according to a preset data compression algorithm, compressing N continuous sampling points inthe sampling signal into one sampling point to obtain a target signal, wherein the information represented by the target signal is consistent with the information represented by the sampling signal; and sending the target signal to the user terminal. The signal receiving end receives the sampling signal and compresses the continuous N sampling points into one sampling point according to the data compression algorithm, so that the frequency of the sampling signal is compressed into 1 / N of the original frequency, and the target signal is obtained; the sampling frequency of the compressed targetsignal is no longer limited by a transmission interface between the signal receiving end and the user terminal, and time synchronization of data between the signal sending end and the user terminal can be realized during asynchronous signal acquisition.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a method, device, electronic device and readable storage medium for realizing asynchronous signal sampling based on FPGA. Background technique [0002] In the prior art, the signal receiving end usually collects signals from the signal sending end, and sends the collected signals to the user terminal. [0003] When collecting a signal of a specific frequency, there are two ways of synchronous signal collection and asynchronous signal collection. When synchronous signal collection is performed, the clock module adjusts the signal collection frequency, that is, the clock module can make the signal frequency actually collected by the signal receiving end consistent with the above-mentioned specific frequency. When performing asynchronous signal acquisition, in order to make the signal clearer, it is often necessary to adjust the acquisition frequency to several t...
