Software and Hardware Platform Technology of Embedded Device Based on Heterogeneous SoC Chip in substation

In order to meet the demand of high-precision harmonic sampling in electronics power grid, and further improve the performance of secondary equipment such as substation measurement and control, PMU and broadband measurement, the application scenarios and performance requirements of high-performance hardware platform are analyzed, and the technical status of domestic chips in mass production is investigated. The hardware platform scheme of heterogeneous SoC chips is adopted, and the dual-system software architecture based on Linux and RTOS system is adopted, We have designed a large-capacity real-time data parallel processing and layered drive technology scheme, fully developed the computing potential of heterogeneous multi-core chips, improved the performance of hardware platform based on domestic chips, and completed the development and testing of the hardware platform of broadband measurement device prototype. Finally, the feasibility of the hardware platform technology scheme based on heterogeneous SoC chips is verified through the comparison of various performance tests.
