摘　　要：根据微机保护系统的发展趋势,提出了一种基于ARM 7内核和CPLD的一种高性能低成本的低压微机保护的硬件平台的设计方案。采用高性能32位ARM LPC 2468保护CPU,通过CPLD完成输入输出扩展和人机接口的控制,配合16位的AD 7657完成多通道高频率采样和保护计算的任务。According to the development trend of microcomputer protection system,a scheme of micro-computer relay protection hardware platform based on ARM7 core and CPLD configuration was put forward. The platform which was designed for low-voltage has the advantage of high-performance and low-cost. The CPU for protection adopted 32 bit-ARM LPC2468 of high-performance,which completed the tasks of multi-channel high-speed sampling and protection calculation through I/O expansion and an-machine interface and communication with CPLD,coordinated with 16 bit-A/D 7657.
