Then , after the circuit is placed wholly into margin within the case of gyroscope , electromagnetic interference which affects circuit itself is analyzed , designing for board level electromagnetic compatibility is discussed , approaches with which reducing electromagnetic interference are bring forward , at same time , the request of every circuit routing is required , and a part of circuit layout is improved 其次,分析了電路安裝在陀螺殼體內(nèi)后的電磁干擾對電路本身的影響,探討了電路板級的電磁兼容性設(shè)計(jì),提出了減小電磁干擾的途徑,在此基礎(chǔ)上提出了電路各模塊的布線要求,并改進(jìn)了部分電路布局。
We discuss the formation of the unidirectional links and their influence on the manet routing protocols such as dsr , dsdv , aodv . solutions are given to overcom e the problems , we analyze some of they and point out their limitations . in the third part , we show a new on - demand routing strategy supported unidirectional links , it use the two circuits route search algorithms to establish the route from the source node to the destination and backward with directions ; it transfer the route error messages from the backward positions to the forward positions one by one ; it apply the packet encapsulation technique to forward the packets through the unidirectional links and introduced the circuit path to transmit information from the forward node to the backward node 接著,指出在移動自組網(wǎng)環(huán)境中,單向鏈路的普遍存在,分析了它的產(chǎn)生原因、它對目前協(xié)議棧的影響;然后,我們給出了一種按需路由的自組網(wǎng)單向鏈路路由算法,它只有在需要路徑的時候才維護(hù)路由,使用二循環(huán)路由尋徑算法以建立節(jié)點(diǎn)間的路徑,使用逐跳逆向傳遞的方式報(bào)告路由終斷,使用封裝廣播的方式沿單向鏈路正向傳輸,使用報(bào)文封裝方式支持單向鏈路下游節(jié)點(diǎn)向上游節(jié)點(diǎn)傳遞信息。
An analytic module of circuit routing is discussed in the thesis , it ' s an assist strategy part added into tnrm , providing intelligent solution of circuit routing . the analysis method takes a good advantage of improving the usage of network and developing the potential , so it is practical for engineering 本課題深入調(diào)研tnrm中的各項(xiàng)功能,研究電路配置的分析方法,采用層次分析法ahp建立分析模型,作為tnrm中電路配置子系統(tǒng)的輔助決策模塊,可提供電路配置方案的智能選擇功能。
Telecommunication network resources management ( tnrm ) is a kind of network management system , which manages equipments and logical resources . tnrm is built on integrated resources database , providing service functions of consultation , design of circuit routing , statistic and analysis for telecom operators 電信網(wǎng)絡(luò)資源管理系統(tǒng)tnrm是一個集網(wǎng)絡(luò)設(shè)備資源管理與業(yè)務(wù)管理于一身的網(wǎng)管系統(tǒng),它建立在完備的資源數(shù)據(jù)庫之上,為電信企業(yè)提供資源查詢、統(tǒng)計(jì)分析、電路配置方案設(shè)計(jì)等業(yè)務(wù)功能。
