基于Linux的嵌入式数据采集装置的TCP/IP通信

TCP /IP Communication of Embedded Data Acquisition Device Based on Linux

为实现数据采集的网络化,将基于TCP/IP协议的网络通信技术应用于数据采集装置,提出以上位PC机为客户端,嵌入式数据采集平台为服务器,并采用多线程编程的通信方案。通过在一台装有Linux系统的PC机上完成发送和接受"hello"和"world"的模拟实验,说明通信过程,实现了嵌入式系统与PC机的高速通信。

To realize networked data acquisition, we present a communication scheme on the basis of client/server mode that uses PC as the client and the embedded data acquisition platform as the server, and uses multithreaded programming to realize communica tion between the two programs. Based on the TCP/IP protocol in data acquisition devices, the communication process is illustrated through a simulation experiment by sending and receiving hello and world on a PC with Linux system, and highspeed communication can eventually be achieved between embedded systems and the PC.
