嵌入式操作系统VxWorks下LXI网络通信的开发

Development of LXI network communication with embedded operating system VxWorks

LXI(LAN eXtension for Instrument)技术是计算机技术、网络技术与仪器技术的有机结合,因此网络通信部分是其必然的组成部分。利用VxWorks这种优秀的嵌入式实时操作系统所集成的TCP/IP网络工具,针对LXI虚拟仪器的开发应用,讨论了采用VxWorks和双缓冲队列实现LXI网络无阻塞通信的方法,并通过工程实践证明了该方法达到了设计要求。

LXI（LAN eXtension for Instrument） is the organic combination of computer technology, LAN technology and instrument technology, and the network communication is its necessary part. VxWorks is an excellent embedded real-time operating system, which integrates TCP/IP network implement. A method to realize the LXI non-blocking network communication with VxWorks and multi-buffering queues was discussed for the development and applications of the LXI virtual instrument. The practice indicated that this method had fulfilled the design demands.
