基于分层结构的无线HART调度策略研究

Research on Wireless HART Scheduling Strategy Based on Hierarchical Structure

采用集中控制通信的思想,提出一种通过图路由方式实现资源调度策略的点对点图路由算法.该算法基于分层结构的基础上采用信号接收强度(RSSI)作为度量选择路由,并提供跳间冗余以确保路由健壮;通过均衡分配信道资源,在网络通信中的所有通信节点之间建立起两点会话.该算法不仅保留了集中式图形路由的可靠性,而且极大地提高了网络通信的抗干扰性.

A point-to-point graph routing algorithm for resource scheduling strategy is proposed by using the idea of centralized control communication.Based on the hierarchical structure,signal reception intensity(RSSI)is used as the measure to select routing,and inter-hop redundancy is provided to ensure the robust routing.By balancing channel resources and establishing two-point conversations between all communication nodes in network communication,the algorithm not only retains the reliability of centralized graphical routing,but also greatly improves the anti-interference ability of network communication.
