Problems solved by technology

[0002] With the improvement of miniaturization and integration of electrical products, high-precision control and acquisition have gradually become the development trend of spacecraft at this stage. High-precision data acquisition and control systems can sense small signals, which is convenient for single-board and system-level fault diagnosis and health management; at the same time, facing the increasing volume and payload of spacecraft, the transmission of control signals through voltage alone will face limitations such as long cables and large transmission voltage drops.

Abstract

The invention relates to an analog acquisition control system and method based on CPCI, and belongs to the technical field of the aerospace testing and the emission control. The multi-core data processing and parallel computing is realized by using one FPGA after adopting a SOPC design method based on the FPGA, the data operation efficiency and processing capacity of the data are greatly improved;a soft-core processor and the traditional FPGA logic resource are in internal interconnection through an internal bus, the internal of the bus chip is closed, and the system has high reliability andstronger environment adaptability.

Description

technical field [0001] The invention relates to a CPCI-based analog quantity acquisition control system and method, belonging to the technical field of aerospace testing and launch control. Background technique [0002] With the improvement of miniaturization and integration of electrical products, high-precision control and acquisition have gradually become the development trend of spacecraft at this stage. High-precision data acquisition and control systems can sense small signals, which is convenient for single-board and system-level fault diagnosis and health management; at the same time, facing the increasing volume and payload of spacecraft, the transmission of control signals through voltage alone will face limitations such as long cables and large transmission voltage drops. Contents of the invention [0003] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art, to provide a CPCI-based analog quantity acquisition c...
