【摘要】：對墻體和屋面進行保溫是實現建筑節(jié)能的主要途徑,聚氨酯板材作為一種性能優(yōu)越的墻體保溫結構,已被世界發(fā)達國家廣泛應用于各類建筑的外墻。其在同類建筑節(jié)能板材中占據比例高達70%以上,而在我國聚氨酯板材在建筑中的使用比例還不到15%。我國“十三五”建筑節(jié)能規(guī)劃明確規(guī)定,在全國范圍內要大力推廣節(jié)能建筑,到2020年全國要實現建筑節(jié)能65%的目標。因此,推廣應用彩鋼聚氨酯夾芯保溫板生產技術是大勢所趨,然而我國彩鋼聚氨酯夾芯保溫板材的大多數生產線生產水平較低,自動化程度和生產效率不高。本文針對這個問題,分析了彩鋼聚氨酯夾芯保溫板生產流水線各生產環(huán)節(jié)的設備組成及其控制要求,根據控制系統的基本設計原則以及生產線設備眾多且分布較廣的特點,設計了一套基于CC-LINK現場總線的彩鋼聚氨酯夾芯保溫板材集散控制系統。根據生產線各環(huán)節(jié)的功能需求,對CC-LINK各站點控制器及執(zhí)行設備進行了硬件選型,以1號從站與主站通信為例,對CC-LINK網絡的各站點的通信配置進行了介紹。從電源電路、電氣控制以及上位機組態(tài)三個方面對控制系統進行了設計,電源電路設計主要包括了主電源電路設計、伺服驅動電源電路設計以及PLC控制回路電源設計。同時給出生產線各環(huán)節(jié)的電氣控制設計以及工藝流程圖,并以切斷機為例,對控制程序進行了詳細講解。從軟件調試、硬件調試、系統調試以及聯機調試幾個方面對生產線的調試工作進行了介紹。其中,軟件調試包括了仿真調試和在線調試兩種方式,硬件調試給出了生產線中主要執(zhí)行器件:異步電機、伺服驅動器和變頻器的調試步驟,并以放卷機、覆膜切斷裝置、切斷機以及堆垛機為例,對系統的調試過程以及調試過程中應注意事項進行了詳細介紹。最后進行了系統聯機調試,闡述了調試過程中遇到的問題及解決辦法。針對彩鋼聚氨酯夾芯保溫板生產線中切斷機定長切割精度不足的問題,本文對切斷機的控制算法進行了研究,討論了一種單值廣義預測控制算法,探討了該算法在上位機WINCC中實現的可行性,并進行了算法仿真實驗。仿真實驗結果證明,該算法能夠在上位機中實現,且與PID算法相比較,其具有更好的動態(tài)特性,十分適合于切斷機這類快速系統。
[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.
