摘要
动力定位系统主要用来解决船舶深海动力定位问题,系统对网络实时性和安全性有着极高的要求。同时动力定位系统网络节点多且网络结构复杂,部分单元控制器和数据采集器往往需要收发两个网络的数据。在深入比较分析各种实时以太网的基础上,选择了具有实时性和安全性的工业以太网POWERLINK为研究对象,采用ZYNQ为硬件平台,提出了在ZYNQ上建立两个MicroBlaze软核分别运行两个独立POWERLINK协议的新方法。该方法能解决控制器双网络平台复用问题,同时还能实现POWERLINK主从站的任意组合,达到优化网络结构和降低成本的效果。最后组建了POWERLINK双协议网络并利用wireshark进行抓包测试,测得两组网络实际参数与设计参数相同且数据交互传输正确,实验结果证明了该方案的可靠性和正确性。
Dynamic positioning system is mainly used to solve the problem of deep-sea dynamic po sitioning. I real-time and security of the network. Dynamic positioning system has many network nodes and complicated network structure. Part of control u-nit and data acquisition unit often need to send and receive two sets of networls data. This thesis researches a real-time and security of in du s trial Ethernet POWERLINK based on the comparative analysis of various kinds of real-time Ethernet. It preMicroBlaze and running two POWERLINK protocol respectively in ZYNQ plat form. This methiod not only can solve the problem of reusing con-troller in the dual networls platform control ler, but also can realize any combination of master-slave stat ions, so as to optimize the structure of network and reduce the cost. Final ly,POWERLINK dual protocol network is tested by Wireshark. The measured parameters of two groups arethe same as the design parameters and data interaction is correct. The reliability and accuracy of the design is proved through experiments.
