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

Abstract

The present application provides a method, device, electronic device and readable storage medium for realizing asynchronous signal sampling based on FPGA, including: receiving a sampling signal, wherein the frequency of the sampling signal is N times the target frequency; The algorithm compresses consecutive N sampling points in the sampled signal into one sampled point to obtain a target signal, wherein the information represented by the target signal is consistent with the information represented by the sampled signal; and the target signal is sent to the user terminal. The signal receiving end receives the sampling signal, and according to the data compression algorithm, compresses consecutive N sampling points into one sampling point, thereby compressing the frequency of the sampling signal to one-Nth of the original, and obtaining the target signal. The sampling frequency of the compressed target signal is no longer limited by the transmission interface between the signal receiving end and the user terminal, and the time synchronization of data between the signal sending end and the user terminal can also be realized during asynchronous signal collection.

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...
