【摘要】：板件拼裝焊接線需要根據(jù)不同板件拼裝焊接對象的工藝要求實現(xiàn)快速響應,從而快速重構(gòu)成適合于新的加工對象的焊接線�？刂葡到y(tǒng)作為板件拼裝焊接線的重要組成部分,其能否實現(xiàn)快速重構(gòu)將直接影響到整個焊接線系統(tǒng)重構(gòu)的效率。但由于板件拼裝焊接線機械系統(tǒng)的高度可重構(gòu)的特點,既需要從系統(tǒng)級角度對焊接線進行重構(gòu),也需要從工作站級的角度對單元模塊進行重構(gòu)。所以一開始就直接研究控制系統(tǒng)的快速重構(gòu)比較困難,可以通過研究其控制系統(tǒng)的快速再設計,即針對機械系統(tǒng)的快速重構(gòu)而使控制系統(tǒng)快速重新設計以適應新的加工系統(tǒng),從而不僅可以快速實現(xiàn)對新的焊接線系統(tǒng)進行監(jiān)控,而且也為控制系統(tǒng)進一步實現(xiàn)快速重構(gòu)奠定了基礎。本論文結(jié)合板件拼裝焊接線的可重構(gòu)特點與控制系統(tǒng)的控制要求,分別從底層控制系統(tǒng)、監(jiān)控軟件以及網(wǎng)絡通信實時性等關鍵技術(shù)對焊接線控制系統(tǒng)如何實現(xiàn)快速再設計進行了研究。首先,對控制系統(tǒng)實現(xiàn)快速再設計的總體方案進行設計。通過對焊接線可重構(gòu)要求與控制工藝的分析,并結(jié)合控制系統(tǒng)總體架構(gòu),提出分別從再設計過程的速度與再設計后的運行穩(wěn)定性兩方面來設計的快速再設計總體方案。其次,以快速再設計過程的速度為出發(fā)點,對底層控制系統(tǒng)與監(jiān)控軟件如何實現(xiàn)快速再設計進行研究。首先通過研究模塊化設計思想與可重構(gòu)系統(tǒng)理論從而提出了基于模塊化選擇與裁剪策略的快速再設計方法,并實現(xiàn)了對底層控制系統(tǒng)的快速再設計。之后通過研究OPC通信技術(shù),并在分析焊接線底層數(shù)據(jù)可配置性的基礎上,提出了“組冗余與項選擇”數(shù)據(jù)配置策略,從而實現(xiàn)監(jiān)控軟件的動態(tài)再設計。最后,以快速再設計后系統(tǒng)運行穩(wěn)定性為出發(fā)點,對焊接線控制網(wǎng)絡再設計后的通信實時性進行研究。在分析PROFIBUS-DP多主站通信協(xié)議的基礎上,通過研究多主站數(shù)據(jù)通信實時性策略,對焊接線多主站網(wǎng)絡在再設計后的總線目標循環(huán)時間進行預估,確保了焊接線網(wǎng)絡在任何再設計組合下的通信實時性。
[Abstract]:Plate assembly welding line needs to achieve rapid response according to the process requirements of different plate assembly welding objects. The control system is an important part of the plate assembly welding line. Rapid reconfiguration will directly affect the efficiency of the reconfiguration of the whole welding line system, but because of the highly reconfigurable characteristics of the mechanical system of the plate assembly welding line, it is necessary to reconstruct the welding line from the point of view of the system level. It is also necessary to reconstruct the unit module from the workstation level, so it is difficult to study the rapid reconfiguration of the control system directly from the beginning, so we can study the rapid redesign of the control system. That is to make the control system quickly redesigned to adapt to the new machining system for the rapid reconfiguration of the mechanical system, so that not only can the rapid implementation of the new welding line system monitoring. This paper combines the reconfigurable characteristics of the plate assembly welding line and the control requirements of the control system, respectively from the bottom control system. Monitoring software and real-time network communication and other key technologies on the welding line control system how to achieve rapid redesign. First of all. Through the analysis of the reconfigurable requirements of the welding line and the control process, and combined with the overall structure of the control system. Put forward the overall scheme of rapid redesign from the two aspects of the speed of the redesign process and the operational stability after the redesign. Secondly, take the speed of the rapid re-design process as the starting point. This paper studies how to realize the rapid redesign of the underlying control system and monitoring software. Firstly, by studying the modular design idea and the theory of reconfigurable system, the rapid redesign based on modularization selection and clipping strategy is proposed. Method. After the research of OPC communication technology, and on the basis of analyzing the configuration of bottom layer data of welding line, the paper realizes the rapid redesign of the bottom control system. The data configuration strategy of "group redundancy and item selection" is put forward to realize the dynamic redesign of monitoring software. Finally, the system running stability after rapid redesign is taken as the starting point. Based on the analysis of PROFIBUS-DP multi-master station communication protocol, the real-time strategy of multi-master station data communication is studied. In order to ensure the real-time communication of welding wire network under any redesigned combination, the target cycle time of the bus is estimated after the redesigned multi-master station network.
