4 . redundancy control can be readily provided and reliability is increased 能方便地提供多重冗余控制。提高了系統(tǒng)的可靠性。
The experimental study of redundancy control in the safety of vacuum absorption wall robot 冗余控制在真空吸附式壁面機(jī)器人安全性方面的實(shí)驗(yàn)研究
redundancy control, part of data collection is used to let data management system make right decision . the embedded operating system vxworks which is used widely in embedded system is implemented as system ’ s software part . vxworks has a micro kernel with highly scalable property, efficient multitask schedule, smart communication between tasks and certain interrupt latency with microsecond level as well 而相應(yīng)的軟件控制部分則依托在嵌入式領(lǐng)域應(yīng)用廣泛的實(shí)時(shí)多任務(wù)操作系統(tǒng)vxworks,它具有高度可剪裁的微內(nèi)核結(jié)構(gòu)、高效的多任務(wù)調(diào)度、靈活的任務(wù)間通信手段、快速靈活的i/o系統(tǒng)、確定的微秒級(jí)中斷延遲時(shí)間等優(yōu)點(diǎn)。
In this paper, the control system of rectifying strip steel deviation based on ppf control algorithm is designed, and a way of detecting the deviation signal of strip steel is introduced, which adopted redundancy control that involves capacitance sensor and highfrequency photoelectricity sensor, and improved reliability of the system . the system includes : siemens s7 200 programmabled logic controller, em235 analog signal module expanded, td200 for manipulating and displaying 本文設(shè)計(jì)了基于ppf控制算法的帶鋼糾偏控制系統(tǒng),并提出采用電容傳感器與高頻光電傳感器冗余檢測(cè)帶鋼偏移信號(hào)的方法,增加了系統(tǒng)的可靠性。系統(tǒng)采用siemenss7-200plc控制,擴(kuò)展了em235模擬模塊,td200用于操作及顯示。
