VPX signal processing backboard

Abstract

The invention provides a VPX signal processing backboard and aims at improving the distributed signal processing capacity, reducing the cost of a distributed system and improving the efficiency by fully utilizing the advantages of a VPX bus. The VPX signal processing backboard comprises a power module, a communication module, a buffer module, a signal preprocessing module and a D / A (Digital to Analog) module, wherein the power module supplies electric power to the VPX signal processing backboard; the communication module receives a data signal detected by each distributed sub-module from a distributed environment and sends a driving signal to the outside; the signal preprocessing module is used for digitally amplifying and digitally filtering the signal; the buffer module is used for temporarily storing an input signal and an output signal of the signal preprocessing module; the D / A module is used for performing analog to digital conversion to generate a driving signal to be output. According to the VPX signal processing backboard, data of the distributed system can be acquired and processed favorably, the robustness of the distributed system is improved, and each monitoring sub-module of the distributed system focuses on the functional development favorably.

Description

Technical field [0001] The present invention relates to a signal processing board, and more specifically, to a VPX signal processing backplane. Background technique [0002] With the rapid development of integrated circuits, computer processing technology, and software technology, data processing system platforms in the aerospace field have shown the following development trends: communication bandwidths are getting wider and higher, transmission rates are getting higher and higher, and real-time processing performance also affects the processing platform. The performance puts forward higher requirements. In addition, due to the special requirements of military, aerospace, aerospace and other fields, traditional computing bus architectures such as PCI and PCI-e can no longer meet the requirements of testing for bus bandwidth and system robustness. Therefore, the data processing platform is required to have higher bus transmission bandwidth, stronger computing power and more flex...

AI Technical Summary

Problems solved by technology

[0004] In the field of distributed systems, the data detected by the distributed detection module is often processed by the server, or sometimes by the detection module, but this structure is not conducive to the situation when the scale of the distributed system reaches a certain level, because it will Causes greater computing pressure on the server, and is prone to data loss problems

On the other hand, if the data processing task is placed on the detection module, the cost of the distributed detection module will be greatly increased
