With the rapid development of Information Science, data acquisition and storage technology has been a very important link in digital signal processing, it is widely used in radar, communications, remote sensing, biomedicine, environmental detection and other fields. It has become an important means for people to obtain external information, realize hardware-in-the-loop simulation and algorithm analysis, and play back real signals collected on the spot.

High-speed data acquisition, storage and playback system has been widely used in aviation, aerospace, ship, electronics, weapons and other defense departments. In order to meet the needs of rapid technological development, the data acquisition frequency and precision, multi-channel data synchronous acquisition, system communication bandwidth, storage speed, continuous storage time, multi-channel real-time storage and reliability, large capacity storage data management, etc. 

Scheme design

The high-speed Data Acquisition and storage and playback system is based on the VXS system architecture and uses the strong real-time RapidIO bus technology, the hardware of the system consists of a main computer, a high-speed data acquisition card, a POWERPC 8640D/8641D signal processing board, a RapidIO switch, an optical fiber storage module and a large-capacity disk array, system software consists of system configuration, system fault diagnosis, real-time data acquisition, signal processing, multi-channel data storage, storage data management, real-time data playback, offline data playback and other functional modules.
