| Abstract: | A high-speed parallel data acquisition system (DAS) is used for the experiment of HL-2A Tokamak. Technology of remote access for stored procedures fetches the setting parameters to meet the demands for the DAS. By using UDP technology, the system can receive the instructions and process automatically. The cards, which are used in this DAS with PXI bus, can work independently in dif ferent threads. The saving method optimizes real -time data storage. It was testified that this system fulfills the scheduled requirements in design with a high reliability. |
