基于TCP/IP通讯的仪器仪表应用层协议架构由于新一代仪器仪表的数据量大，传输距离远，实时性高，传统的基于RS232/RS485的串行数据传送方式已不能满足要求，而基于TCP/IP的以太网数据通讯方式,传输距离大(通过internet，理论上无限远)，速度快，是当前新一代仪器仪表数据传输的理想方式。
基于单片机(如MCS51+RTL8019AS)的以太网接入技术已经相当成熟，可以方便的与PC机连接。根据仪器仪表嵌入式应用的要求（如实时性），我们采用TCP协议或UDP协议进行数据传输。TCP是一种可靠的传输协议，但效率相对较低，UDP是一种由用户自己来保证传输可靠性的传输协议，但效率较高。
本协议目前采用TCP，以太网接口模块作为服务器方，任何时候仅提供一个连接。
本文档的适用范围为带有以太网接口模块的仪器仪表。
Instruments based application layer protocol architecture TCP/IP communication since the new generation of instrumentation data capacity, transmission distance, high real-time, based on the traditional serial data transfer mode RS232/RS485 can not meet the requirements, and based on TCP/IP Ethernet data communication mode, the transmission distance is large (via internet, theoretically infinite) speed, is the ideal way to present a new generation of instrumentation data transmission.
Microcontroller-based (such as MCS51+ RTL8019AS) Ethernet access technology is already quite mature, it can be easily connected to a PC. According instrumentation embedded applications (such as real-time), we use the TCP protocol or UDP protocol for data transmission. TCP is a reliable transport protocol, but the efficiency is relatively low, UDP is a transmission by the users themselves to ensure the reliability of the transmission protocol, but more efficient.
