Implementation of IEEE 1588 Protocol over Industrial Ethernet
为满足电力等分布式测控系统对时钟同步的高精度要求,采用TI公司支持IEEE 1588协议的Cortex-M3核ARM芯片作为微处理器,设计并实现一种基于中断优先级的前/后台框架的精密时钟网络服务器.由于选用轻量级TCP/IP协议栈(LwIP)和简化同步协议设计底层通信软件,能减轻处理器负担,实时性能得到改善.测试实验结果表明,该设备同步精度高、稳定性好、成本低,具有较好的应用前景.
An IEEE 1588 server, which is based on the foreground/background system with the priorities of interrupts, is designed and implemented to meet the high precision requirement of time synchronization in distributed power systems by using an ARM(@)CortexTM-M3 based microcontroller, which supports IEEE 1588 protocol. The burden of microcontroller is reduced and the real-time performance is further improved as a result of adopting the lightweight TCP/IP stack and…查看全部>>
