摘要
在由 8 位单片机构成的嵌入式系统上实现 TCP/IP 协议栈,采用虚拟仪器模块设计虚拟仪器网络通信程序,实现虚拟仪器和嵌入式系统基于用户数据包协议(UDP)运输层协议的网络通信。对标准的 UDP 端到端通信加以改进,增加握手通信过程,以实现测控命令的可靠传输。对标准 TCP/IP 底层网络协议进行简化和改进,以减轻单片机的处理负担,提高网络速度,同时保证数据通信的可靠性。通过大量数据的网络传输实验,验证了协议简化和改进的有效性。
The Ethernet communication betweeen virtual instruments and embedded systems is presented. TCP/IP protocol is realized in the embedded systems that are constructed by 8-bit microcontrollers,and the Ethernet communication virtual instrument blocks are designed and deployed. The hand-shaking is added to the standard end-to-end network communication based on UDP pro- tocol. This makes the UDP protocol suitable and reliable for transmission of the commands. The predigestion and improvement on the standard TCP/IP protocol relieve the processing burden of MCUs. This in turn improves the network rate and ensures the transmission reliability. The validity of the predigestion and improvement has been justified by the reliable transmitting of a great quantity of data.
