High-speed data acquisition and real-time transmission system and method based on dual-port RAM (Random Access Memory)

Abstract

The invention relates to a high-speed data acquisition and real-time transmission system and method based on a dual-port RAM (Random Access Memory). A high-speed data acquisition module with an FPGA processor as a core processing unit is used for controlling a data acquisition card to perform high-speed data acquisition, and the acquired high-speed data is processed and then stored in a data storage module based on a dual-port RAM mechanism realized in an FPGA; a data real-time transmission module with an embedded ARM processor as a core processing unit is used for reading data in a data storage module and processing the data, and then the data is constructed into data frames for real-time transmission according to a real-time Ethernet transmission protocol. According to the invention, the problem that the real-time performance of data acquisition is seriously influenced due to the fact that a data acquisition and transmission system occupies a large amount of resources of a processor in the process of transmitting a large amount of acquired data is solved, so that high-efficiency and high-reliability acquisition and real-time transmission of large-scale data are realized; and the method has the advantages of low cost, mature application technology, wide application range, good expandability and the like, and has a wide application prospect.
