在以通用伺服电机控制系统为下位机的基础上,开发了以实时内核μC/OS II、DSP、CPLD 控制模块为核心的软硬件平台。通过移植 uIP 协议栈到 DSP,在通信应用层上将 Modbus 帧嵌入到 TCP 帧中,简单可靠地实现了 Modbus/TCP 协议。同时将 Modbus/TCP 协议与μC/OS II 实时内核进行整合,更好地保证了系统调度的实时性。

Taking general servo motor control system as the lower computer,the software and hardware platform based on real-time ker-nel μC/OS-II,DSP and CPLD controller is developed.By transplanting uIP protocol stack to DSP,the Modbus frame is embedded to the TCP frame in the communication application layer,the Modbus/TCP protocol is simply and reliably realized.Meanwhile,the Modbus/TCP protocol and the real-time kernel μC/OS-II are integrated in order to ensure the real-time scheduling of system.
