【摘要】 当前,电脑提花簇绒机的使用越来越多,相对于传统的簇绒机,它既可大大减少传统印花工艺所带来的环境污染,同时所制作的地毯产品质量明显提高。限于控制系统的缺乏,国内企业所使用的电脑提花簇绒机,基本上从国外进口,不仅价格昂贵,而且维修不便,严重制约了地毯企业的市场竞争能力。为此,论文进行了平割高低圈绒簇绒机控制系统的研究与开发,论文研究既具有一定的理论意义,又具有较大的实用价值。首先,论文对平割高低圈绒簇绒控制系统的国内外研究现状进行了综述,阐述了控制系统研发的意义,提出了以工控机为上位机,以单片机为下位机核心,以变频器、PLC为辅件的控制系统方案。在对平割高低圈绒簇绒机机械原理分析的基础上,进行了簇绒机控制系统的总体方案设计,详细分析了上位机软件原理结构、下位机子系统结构以及控制系统的功能。接着,论文对控制系统开发中的几个关键技术进行了研究。给出了位图文件在上位机中的处理方法以及上下位机之间的通信处理机制,进行了控制系统的下位机电路板硬件设计,分析了下位机系统在运行过程中遇到的干扰问题,并提出了相应的可靠性设计方法。最后,进行了平割高低圈绒簇绒机控制系统各个部分的连接设计,并与机械本体部分一起进行了联机调试,调试表明:所研发的控制系统各项指标均达到设计标准。目前,配备该控制系统的簇绒机已实际用于某地毯生产企业,系统运行正常。系统的成功开发,对开发其它类型簇绒机控制系统有借鉴作用,并可有效提升我国地毯企业的装备技术水平。更多还原

【Abstract】 Computer Control Tufting Machine (CCTM) is currently used in textile industry more and more popularly. Compared with traditional tufting machine, CCTM reduce pollution and produces higher quality carpet mate. For lacking of CCTM control system, many CCTMs have to be imported with high price and potential maintenance inconvenience. This greatly restricts the market competency of domestic textile factories. For that, this paper presents the research and development of Level Cut and High-Low-Loop Pile Tufting Machine Control System (LCHLTMCS). This research may have not only theory significance but also practicality value.Firstly, this paper summarizes the status quo of LCHLTMCS at home and abroad and expatiates the importance of researching and developing LCHLTMCS. After that, the blue print of control system is put forward. In the blue print, Industry PC (IPC) acts as upper computer, MCU as a core of lower computer, and transducer and PLC as accessory. Based on the analysis of Level Cut and High-Low-Loop Pile Tufting Machine machinery principle, the blue print of control system is designed. The software architecture, lower computer subsystem and functions of control system are all detailed.Secondly, some key technologies are studied. The method of bitmap file in upper computer is proposed. Process of communication between upper computer and lower computer is detailed. The kernel PCB design of lower computer system is also presented. Besides, potential interferences for control system and some measurements are discussed.Finally, this paper presents the control system interconnection and the test of control system assembled on tufting machine. The test results make clear that the control system reach the target of design.At present, tufting machine (TM) with the control system has successfully run in some carpet factory. The development and research of LCHLTMCS may have reference value to develop other similar system and improve the level of equipment technology in domestic carpet factories.更多还原
