Description
technical field [0001] The invention relates to the field of data processing and transmission for secondary system testing and simulation of an intelligent substation, in particular to an application-oriented multi-channel SRIO DMA transmission system, and also relates to an application-oriented multi-channel SRIO DMA transmission method. Background technique [0002] With the large-scale promotion and application of smart substations, the testing and simulation of secondary equipment such as merging units, protection devices, intelligent terminals, and measurement and control devices in substations is becoming more and more extensive. Relay protection testers, combined unit testers and other test instruments are used. Due to the small number of interfaces, weak data calculation capabilities, and low bus bandwidth of these testers, they can only be tested on a single device, and cannot be used for the entire interval or multiple protection devices or Overall testing and simu...
