摘　　要：文中提出了一种支持多客户端连接的TCP Server的嵌入式软硬件设计方案。该网络服务器以Cortex-M4芯片STM32F407VET6为核心控制器,通过RMII接口与LAN8742A以太网收发器进行网络数据交互。此外,文中将LwIP协议栈移植到FreeRTOS实时操作系统中,并根据TCP客户端连接情况,动态创建或消除相应客户端的网络通信线程。研究证明,TCP Server最大可支持4个客户端同时连接,进行稳定的网络数据传输,有效解决了嵌入式网络系统仅单点连接的问题。This paper put forward a design scheme of software and hardware for multi-connected TCP Server in embedded system.The network server used Cortex-M4 chip STM32F407VET6 as the core controller,via RMII bus connected to LAN8742A Ethernet transceiver to process network data.Furthermore,the LwIP protocol stack was transplanted into FreeRTOS real-time operating system,and according to the connections of TCP clients,the TCP server can dynamically create and delete the corresponding communication processing thread.Research proves that the TCP Server supports a maximum of 4 client connections for steady network data transmission,which can effectively solve the problem of point to point connection for embedded network system.
