FPGA-based (field programmable gate array-based) embedded dual-core relay protecting system

Abstract

The invention provides an FPGA-based embedded dual-core relay protecting system. The FPGA-based embedded dual-core relay protecting system comprises a first NIOS II soft-core processor, a second NIOS II soft-core processor, an Avalon bus module and a mailbox module. The mailbox module is connected with the first NIOS II soft-core processor, the second NIOS II soft-core processor and the Avalon bus module. The FPGA-based embedded dual-core relay protecting system integrates the digital system onto one chip and accordingly is high in function density, small in size, low in power consumption and high in reliability; compared with a special ASIC (application specific integrated circuit), FPGA is low in cost and flexible in design and is the development tendency of integrated circuit design of future microcomputer relay protecting products; the FPGA-based embedded dual-core relay protecting system comprises data collection, logic processing and a variety of peripheral systems and can meet the requirements of hardware interfaces on diversification and customization.

Description

technical field [0001] The invention relates to the technical field of medium and low voltage microcomputer relay protection, in particular to an FPGA-based embedded dual-core relay protection system. Background technique [0002] At present, in the design of the product platform of low-voltage automation equipment in the power system, 90% of the products use special ASIC chips such as single-chip microcomputers, ARM or DSP. The performance of the whole machine system is greatly restricted due to the limitation of line delay, as well as its own size and weight, and the product MTBF (mean time between failure) value is low. With the continuous proposal and development of various complex algorithms in the power system and the new progress of communication technology, the performance of the traditional dedicated ASIC chip processor is challenged, and it is no longer good to rely solely on improving the clock frequency, data throughput and other indicators. To meet the need...
