AI acquisition system and AI acquisition device thereof

Abstract

The invention discloses an AI acquisition device, which performs common-mode voltage adjustment and differential-mode gain adjustment on a differential voltage signal converted by a differential voltage acquisition circuit through a differential amplifier so as to meet the input requirement of an analog-to-digital converter, so that the analog-to-digital converter performs analog-to-digital conversion on the differential voltage signal to obtain a digital signal, therefore, AI collection is completed. Besides, on one hand, the anti-aliasing matching circuit can be used as a low-pass filter to filter high-frequency interference and improve the acquisition precision, and on the other hand, the anti-aliasing matching circuit can store and raise the potential of the input end of the differential amplifier through the electric energy of the anti-aliasing matching circuit and improve the sampling frequency of the analog-to-digital converter, namely, the acquisition speed of the AI is improved. The invention also discloses an AI acquisition system which has the same beneficial effects as the AI acquisition device.

Description

technical field [0001] The present invention relates to the field of signal collection, in particular to an AI collection device, and also to an AI collection system. Background technique [0002] Analog signal is a common signal form that can be used for data transmission. Many devices (such as most sensors) usually use analog signals when transmitting data. Analog signals are usually collected into the controller for use. The real-time nature of analog signals And precision are two important indicators. The existing technology lacks a mature AI (Analogy Input, analog input) acquisition device, and it is difficult to guarantee a high acquisition speed and acquisition accuracy at the same time. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Contents of the invention [0004] The purpose of the present invention is to provide an AI acquisition device. On the one hand, the an...
