Embodiment Construction

[0023] The multi-channel signal acquisition platform based on the VPX architecture is a standard VPX architecture 6U board, which is mainly composed of a radio frequency receiving channel module and a digital acquisition module. The radio frequency receiving channel module receives radio frequency signals from the antenna, and completes signal filtering, amplification, frequency conversion, etc. Work, and output the processed intermediate frequency signal to the digital acquisition module for subsequent processing. The digital acquisition module is the core module of the whole system, which mainly completes the work of intermediate frequency signal acquisition, signal processing, interface transmission, and external control. figure 1 The overall framework of the multi-channel signal acquisition platform based on VPX architecture is given.

[0024] 1. RF receiving module

Abstract

The invention relates to the technical field of data acquisition and transmission, and provides a multichannel signal acquisition technical scheme to realize signal acquisition and processing. Therefore, the technical scheme adopted by the invention is as follows: a multichannel signal acquisition system based on VPX architecture comprises a radio frequency receiving channel module, a digital acquisition module and an antenna, the radio frequency receiving channel module receives a radio frequency signal from the antenna and completes filtering, amplification and frequency conversion of the signal; the processed intermediate frequency signal is output to the digital acquisition module for subsequent processing; and the digital acquisition module completes intermediate frequency signal acquisition, signal processing, interface transmission and external control. The system is mainly applied to data acquisition and transmission occasions.

Description

technical field [0001] The invention relates to the technical field of data acquisition and transmission, in particular to a multi-channel signal acquisition system based on VPX architecture. [0002] Note: VPX is a new generation of high-speed serial bus standard proposed by VITA (VME International Trade Association, VME International Trade Association). Background technique [0003] With the continuous development of information technology, the signal acquisition system is also constantly updated, especially in the fields of radar, aerospace and aviation, the increasing demand for the acquisition rate, processing bandwidth, data transmission rate and system versatility of the signal acquisition system Higher requirements have been put forward in terms of capabilities [1]. The traditional general-purpose platform for signal acquisition, such as CPCI (Compact Peripheral Component Interconnect Standard) bus interface, etc. can no longer meet the needs of the current system [...
