HiSLIP协议的研究与应用

Research and Application of HiSLIP Protocol

为解决无LAN口仪器仪表网络接入问题,仪器的网络代理应运而生。当前网络代理的仪器控制机制主要基于TCP/UDP协议,仪器控制及网络传输数据效率较低,为此,IVI联盟制定了标准的仪器控制协议HiSLIP。通过对该协议的功能和交互过程的详细分析,根据协议规范实现协议的运行代码,并基于此协议设计出仪器网络代理,可以实现对支持VXI仪器的便捷网络接入和高效控制,降低通信时延和网络带宽对仪器测量的影响,满足网络化测控系统中对仪器实时性的要求。

In order to solve the problem of instrument network access of no LAN port, the instrument network a- gency arose. The instrument control mechanism of current agency is mainly based on the TCP/UDP protocol, instrument control and network data transmission are inefficiency. Therefore, IVI alliance has formulated the standard special HiSLIP instruments control protocol. Through analyzing the functions and the interaction processes of this protocol, the protocol is realized according to specifications, and instrument network agency is designed. The VXI instrument can be accessed to network conveniently and be controlled efficiently, the instru- ment measuring influence to the communication time-delay and network bandwidth is reduced, the requirement of real-time is met in the network measurement and control system.
