【摘要】：柔性制造系統(tǒng)(FMS)以其柔性、高效率的特點在先進制造業(yè)領域得到了迅速的發(fā)展和推廣。隨著我國高等教育的發(fā)展,高校對用于FMS教學實驗的訓練系統(tǒng)需求日益增多,但目前國內(nèi)市場FMS訓練系統(tǒng)產(chǎn)品短缺,且現(xiàn)有產(chǎn)品成本高,能耗和實驗占地面積較大,影響了其在實驗室環(huán)境下的應用,所以開發(fā)規(guī)模小型化和功能模塊化的桌面型FMS用于教學實驗很有意義。 FMS高效可靠運行的實現(xiàn)離不開功能完備的監(jiān)控系統(tǒng),監(jiān)控系統(tǒng)不僅要能夠實時采集到FMS運行時設備的加工、狀態(tài)信息,還要能夠根據(jù)采集到的信息進行分析處理,做出正確的控制決策。因此,開發(fā)桌面型FMS的監(jiān)控系統(tǒng)對整個系統(tǒng)的開發(fā)至關重要。 本文首先對FMS進行了介紹,研究了工業(yè)以太網(wǎng)技術應用于桌面型FMS的可行性。然后分析和研究了FMS中的生產(chǎn)調度問題及其工作流程,結合桌面型FMS的組成和執(zhí)行的作業(yè)計劃特點,制定了實用、操作性強的調度規(guī)則。最后,在分析和研究桌面型FMS監(jiān)控系統(tǒng)的監(jiān)控對象和結構層次的基礎上,設計實現(xiàn)了采用二級控制結構的監(jiān)控系統(tǒng),并在Visual C++環(huán)境下開發(fā)了配套的監(jiān)控軟件。 課題所開發(fā)的桌面型FMS監(jiān)控系統(tǒng)利用工業(yè)以太網(wǎng)技術實現(xiàn)了設備的互聯(lián)和監(jiān)控信息的收發(fā),利用基于規(guī)則的調度方法解決了生產(chǎn)調度問題,利用計算機仿真技術實現(xiàn)了設備離線調度仿真,并縮短了整個系統(tǒng)的開發(fā)周期。經(jīng)實踐檢驗,該監(jiān)控系統(tǒng)能夠滿足桌面型FMS的監(jiān)控要求。
[Abstract]:Flexible manufacturing system (FMS) has been rapidly developed and popularized in the field of advanced manufacturing because of its flexibility and high efficiency. With the development of higher education in China, the demand for training system for FMS teaching experiment is increasing day by day. However, at present, there is a shortage of FMS training system products in domestic market, and the cost of existing products is high, and the energy consumption and experimental area are large. It has influenced its application in laboratory environment, so it is meaningful to develop desktop FMS with miniaturization and function modularization for teaching experiment. The efficient and reliable operation of FMS can not be achieved without a complete monitoring system. The monitoring system should not only collect the processing and status information of the FMS running equipment in real time, but also be able to analyze and process the collected information and make the correct control decision. Therefore, the development of desktop FMS monitoring system is very important to the development of the whole system. In this paper, FMS is introduced, and the feasibility of the application of industrial Ethernet technology to desktop FMS is studied. Then, the production scheduling problem and its workflow in FMS are analyzed and studied. Combined with the composition of desktop FMS and the characteristics of execution job plan, the practical and operational scheduling rules are formulated. Finally, on the basis of analyzing and studying the monitoring objects and structure levels of desktop FMS monitoring system, a monitoring system with two-level control structure is designed and implemented, and a supporting monitoring software is developed under the Visual C environment. The desktop FMS monitoring system developed in this paper realizes the interconnection of equipment and the sending and receiving of monitoring information by using industrial Ethernet technology, and solves the problem of production scheduling by using the rule based scheduling method. The off-line scheduling simulation of equipment is realized by using computer simulation technology, and the development cycle of the whole system is shortened. It is proved by practice that the monitoring system can meet the monitoring requirements of desktop FMS.
