基于S3C2410芯片的掉电保护系统设计

Power-fail Protection System Based on S3C2410 Chip Design

云计算数据中心UPS的要求较高,为了在断电时能正常运行系统,基于ARM9系列的S3C2410,使用μC/OS-II内核实现了断电保护系统.通过分析掉电保护基本硬件平台,首先进行基于S3C2410芯片的精简掉电保护模块设计:UART控制模块、电源模块、晶震模块和JTAG电路模块.然后,进行了断电保护电路硬件芯片设计.最后,给出了整体系统软件程序设计:等待捕获方式和μC/OS-II内核调用方式.基于S3C2410芯片和μC/OS-II内核的掉电保护系统解决了数据中心供电系统中掉电保护的需求,能够实时捕捉到掉电信号并保存系统状态,恢复现场数据.

In order to ensure the system run normally, the uC/OS - II kernel power -fail protection system was de- signed by using S3C2410 based on ARM9. Basic hardware platform based on the analysis of power- fail protection was analyzed. Based on S3C2410 chip and uC/OS -II kernel power- fail protect -ion sys- tem, it can satisfy the data center of power - fail protection demand of power supply system. At the same time, it can capture the real- time electrical signal and save the system state, restore the scene data.
