Micro-signal detection device and detection method thereof

Abstract

The present invention provides a tiny signal detection device, comprising: an energy acquisition circuit module, which includes a pre-storage module and a high-frequency charge-discharge control module, wherein the pre-storage module temporarily stores the energy of a tiny signal, wherein the The high-frequency charging and discharging control module obtains the energy in the pre-storage module, and the high-frequency charging and discharging control module outputs energy at a certain frequency; and an information acquisition circuit module, wherein the high-frequency charging and discharging control module Providing energy to the information acquisition circuit module, wherein the information acquisition circuit module acquires information from the tiny signal to obtain a detection result of the tiny signal, so as to transmit the detection result of the tiny signal. In addition, a small signal detection method is provided.

Description

technical field [0001] The invention relates to the field of signal identification and detection, in particular to a detection device and a detection method for the acquisition and further processing of tiny signals. Background technique [0002] Today, every signal generated in production has a certain meaning. For those signals with obvious characteristics and meanings, the main technical difficulties lie in acquisition, filtering or proper interpretation. However, many tiny signals also have certain representative significance, but are often ignored or missed because they cannot be obtained in time. Only when the small problem represented by the small signal rises to a certain level and becomes a big problem and sends out a big signal can it be obtained. This process of quantitative change leading to qualitative change can be detected and diagnosed from the small signal at the initial stage. [0003] Usually, it is necessary to detect the existence of some weak sudden ac...

Problems solved by technology

Then, the possibility of misoperation is very high, because the information may be incomplete, or the key information may be processed in the process

[0005] In particular, a small pulse signal that exists discontinuously is difficult to obtain in traditional detection
