【摘要】：柔性制造系统(FMS)以其柔性、高效率的特点在先进制造业领域得到了迅速的发展和推广。随着我国高等教育的发展,高校对用于FMS教学实验的训练系统需求日益增多,但目前国内市场FMS训练系统产品短缺,且现有产品成本高,能耗和实验占地面积较大,影响了其在实验室环境下的应用,所以开发规模小型化和功能模块化的桌面型FMS用于教学实验很有意义。 FMS高效可靠运行的实现离不开功能完备的监控系统,监控系统不仅要能够实时采集到FMS运行时设备的加工、状态信息,还要能够根据采集到的信息进行分析处理,做出正确的控制决策。因此,开发桌面型FMS的监控系统对整个系统的开发至关重要。本文首先对FMS进行了介绍,研究了工业以太网技术应用于桌面型FMS的可行性。然后分析和研究了FMS中的生产调度问题及其工作流程,结合桌面型FMS的组成和执行的作业计划特点,制定了实用、操作性强的调度规则。最后,在分析和研究桌面型FMS监控系统的监控对象和结构层次的基础上,设计实现了采用二级控制结构的监控系统,并在Visual C++环境下开发了配套的监控软件。课题所开发的桌面型FMS监控系统利用工业以太网技术实现了设备的互联和监控信息的收发,利用基于规则的调度方法解决了生产调度问题,利用计算机仿真技术实现了设备离线调度仿真,并缩短了整个系统的开发周期。经实践检验,该监控系统能够满足桌面型FMS的监控要求。
[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.
