【摘要】：对墙体和屋面进行保温是实现建筑节能的主要途径,聚氨酯板材作为一种性能优越的墙体保温结构,已被世界发达国家广泛应用于各类建筑的外墙。其在同类建筑节能板材中占据比例高达70%以上,而在我国聚氨酯板材在建筑中的使用比例还不到15%。我国“十三五”建筑节能规划明确规定,在全国范围内要大力推广节能建筑,到2020年全国要实现建筑节能65%的目标。因此,推广应用彩钢聚氨酯夹芯保温板生产技术是大势所趋,然而我国彩钢聚氨酯夹芯保温板材的大多数生产线生产水平较低,自动化程度和生产效率不高。本文针对这个问题,分析了彩钢聚氨酯夹芯保温板生产流水线各生产环节的设备组成及其控制要求,根据控制系统的基本设计原则以及生产线设备众多且分布较广的特点,设计了一套基于CC-LINK现场总线的彩钢聚氨酯夹芯保温板材集散控制系统。根据生产线各环节的功能需求,对CC-LINK各站点控制器及执行设备进行了硬件选型,以1号从站与主站通信为例,对CC-LINK网络的各站点的通信配置进行了介绍。从电源电路、电气控制以及上位机组态三个方面对控制系统进行了设计,电源电路设计主要包括了主电源电路设计、伺服驱动电源电路设计以及PLC控制回路电源设计。同时给出生产线各环节的电气控制设计以及工艺流程图,并以切断机为例,对控制程序进行了详细讲解。从软件调试、硬件调试、系统调试以及联机调试几个方面对生产线的调试工作进行了介绍。其中,软件调试包括了仿真调试和在线调试两种方式,硬件调试给出了生产线中主要执行器件:异步电机、伺服驱动器和变频器的调试步骤,并以放卷机、覆膜切断装置、切断机以及堆垛机为例,对系统的调试过程以及调试过程中应注意事项进行了详细介绍。最后进行了系统联机调试,阐述了调试过程中遇到的问题及解决办法。针对彩钢聚氨酯夹芯保温板生产线中切断机定长切割精度不足的问题,本文对切断机的控制算法进行了研究,讨论了一种单值广义预测控制算法,探讨了该算法在上位机WINCC中实现的可行性,并进行了算法仿真实验。仿真实验结果证明,该算法能够在上位机中实现,且与PID算法相比较,其具有更好的动态特性,十分适合于切断机这类快速系统。
[Abstract]:Thermal insulation of wall and roof is the main way to realize building energy saving. As a kind of wall insulation structure with superior performance, polyurethane sheet has been widely used in all kinds of building exterior wall in developed countries all over the world. It occupies more than 70% in the similar building energy saving sheet, but the proportion of polyurethane sheet used in the building is less than 15bard in our country. In the 13th Five-Year Plan of our country, it is clearly stipulated that energy-saving buildings should be popularized throughout the country, and the goal of building energy saving should be achieved by 2020. Therefore, it is the trend of the times to popularize the production technology of polyurethane core insulation board of color steel. However, the production level of most production lines of polyurethane core insulation board of color steel in China is relatively low, and the degree of automation and production efficiency is not high. In order to solve this problem, this paper analyzes the equipment composition and control requirements of the production line of polyurethane core insulation board of Caigang. According to the basic design principles of the control system and the characteristics of the large number of production line equipments and the wide distribution of the production line, Based on CC-LINK field bus, a distributed control system for polyurethane core insulation plate of color steel was designed. According to the functional requirements of each link of production line, the hardware selection of CC-LINK station controller and execution equipment is carried out. Taking the communication between No. 1 slave station and master station as an example, the communication configuration of CC-LINK network stations is introduced. The control system is designed from three aspects: power supply circuit, electrical control and upper computer configuration. The power circuit design mainly includes main power circuit design, servo drive power circuit design and PLC control circuit power supply design. At the same time, the electrical control design and process flow chart of each link of the production line are given, and the control program is explained in detail taking the cutting off machine as an example. The debugging work of production line is introduced from software debugging, hardware debugging, system debugging and on-line debugging. The software debugging includes simulation debugging and on-line debugging. The hardware debugging gives the debugging steps of the main components in the production line: asynchronous motor, servo driver and frequency converter. The debugging process of the system and the matters needing attention in the debugging process are introduced in detail. Finally, the system on-line debugging is carried out, and the problems encountered in the debugging process and the solutions are expounded. In order to solve the problem of insufficient cutting precision of cutting machine in polyurethane core insulation board production line, the control algorithm of cutting machine is studied in this paper, and a single value generalized predictive control algorithm is discussed. The feasibility of the algorithm in WinCC is discussed, and the algorithm simulation experiment is carried out. The simulation results show that the algorithm can be implemented in the upper computer, and compared with pid algorithm, the algorithm has better dynamic characteristics and is very suitable for fast systems such as cutting off machine.
