一种工业无线自适应退避竞争接入方法的研究
Study on an adaptive keeping-off competition access method of industrial wireless networks
摘要
Abstract
Wireless communication has become a hot research topic in the industrial network. The traditional polling method has the advantages of high stability and reliability,but it cannot provide real-time monitoring for abnormal data of subnodes. A method of adaptive keeping-off competition scheduling to guarantee abnormal data′s real-time access to the channel is designed in this paper. In this method,the polling mode is adopted as the basic communication mode,superframe structure is designed to provide the slot time for data access,and the adaptive keeping-off competition method is adopted to avoid channel collisions. The experimental results show that the method of accessing abnormal data to the channel has high real-time performance and reliability,which can satisfy the strict requirements for abnormal data transmission in industry.关键词
