Super-multichannel embedded high-speed signal acquisition and processing system and method

Abstract

The invention discloses a super-multichannel embedded high-speed signal acquisition and processing system and method. The system comprises an upper host; a switch in communication connection with theupper host; a plurality of transmission processing units in communication connection with the switch; multiple acquisition control units, wherein each acquisition control unit comprises a plurality ofADC acquisition channels, a plurality of conditioning circuits and a first FPGA, the conditioning circuits being in communication connection with the ADC acquisition channels and being in one-to-onecorrespondence with the ADC acquisition channels, the ADC acquisition channels being in communication connection with the first FPGA, and the first FPGA being electrically connected with the transmission processing unit through a multi-channel SPI bus; and a plurality of sensor modules, at least one sensor module being electrically connected with one conditioning circuit, and the first FPGA beingin communication connection with the sensor modules. The problems that in an existing signal collecting and processing system, the number of collecting channels is small, and a large signal collectingsystem is not easy to form are solved, and the problems that an existing signal collecting and processing method cannot achieve variable delay collection among multiple collecting channels and largedata volume real-time processing are solved.

Description

technical field [0001] The present application relates to the technical field of signal acquisition, in particular to an ultra-multi-channel embedded high-speed signal acquisition and processing system and method. Background technique [0002] At present, with the development and application of ARM (Advanced RISC Machine), FPGA (Field Programmable Gate Array, Field Programmable Logic Gate Array) and DSP (Digital Signal Process, digital signal processing) technology, signal data acquisition and processing technology has developed rapidly. [0003] However, in the existing signal acquisition and processing system, there are problems that there are few acquisition channels and it is difficult to form a larger signal acquisition system. In addition, the signal acquisition and processing system must have signal acquisition, real-time processing, digital filter bandwidth selection, and user interaction. In addition to functions such as parameter setting, it is also necessary to su...
