| 中文摘要: |
| 为了实现通信处理器模块通信的功能,在实时操作系统uC/OS II和ARM7内核的软硬件平台上,通过移植LwIP到ARM开发平台提出了一种支持多线程实时应用的嵌入式TCP/IP协议栈的方案。在通讯应用层上,将Modbus帧嵌入到TCP帧中,分析研究Modbus/TCP协议通信结构模型,最终简单可靠地实现了嵌入式Modbus/TCP通信协议。结果表明,结合Modbus/TCP通信协议,可通过创建多个线程函数,稳定有效地实现Modbus/TCP客户端/服务器端之间数据的传送。 |
| 英文摘要: |
| To realize the functions of communications processor module, an embedded TCP/IP protocol stack was proposed based on the uC/OS II real time operating system and the hardware platform of ARM7 kernel, which can support multi threaded real time application by transplanting the LwIP to ARM development platform. On the communication application layer, the Modbus frames was embedded to the TCP frames, and the Modbus/TCP protocol communication structure model was analyzed, in order to ultimately achieve the embedded Modbus/TCP communication protocol simply and reliably. The results indicated that the Modbus/TCP data transfer between client and server was realized stably and effectively by combining with Modbus/TCP protocol and establishing several thread functions. |
