【摘要】： 噴繪設備作為廣告設備及技術發(fā)展的新興成果,一經(jīng)問世,就在全球范圍內迅速普及發(fā)展開來。而大幅面數(shù)碼彩色噴繪機的問世,則是在廣告制作領域注入了新的力量,使得戶外廣告越來越被人們所接受和重視,極大地推動了戶外廣告媒體的發(fā)展。另一方面,伴隨著電子技術與軟件技術的飛速發(fā)展,嵌入式系統(tǒng)開發(fā)技術越來越廣泛的應用在生產和消費的各個領域,同時也更加推動了噴繪設備無論在速度和精度上都走向一場重大的變革。 噴繪設備是采用噴繪技術在特制的基材上噴印特定畫面的大型設備,而噴繪技術中目前使用得最多的也是最具有優(yōu)勢的就是數(shù)字壓電技術。該技術中對于噴頭的控制尤為重要,直接關系到噴繪設備的速度和精度。 本文設計了一種相對于數(shù)據(jù)傳輸而獨立出來的噴繪設備的控制系統(tǒng),不僅提高了設備通信的速度和效率,更增加了設備的靈活性和使用性�？刂葡到y(tǒng)采用了韓國三星公司推出的16/32位RISC微處理器S3C2440A作為噴繪設備的主控制處理器,利用NEC公司新推出的78K0503D作為噴頭的控制芯片,通過實現(xiàn)IIC通信來控制高精度噴頭的噴印工作。本文介紹了噴繪設備噴頭的工作原理和ARM處理器,詳細介紹了控制系統(tǒng)的設計架構和系統(tǒng)組成,介紹了硬件部分和相關電路的設計。在軟件方面,完成了對控制信號結構的設計定義,并利用軟件分層和緩沖隊列提高數(shù)據(jù)傳輸效率,實現(xiàn)了主控制器和控制芯片的通信,給出了通信流程和流程代碼,最后搭建驗證平臺,進而給出最終的結果和分析。
[Abstract]:As a new achievement of advertising equipment and technology development, inkjet painting equipment has developed rapidly in the world. However, the advent of large format digital color inkjet painting machine has injected new power into the field of advertising production, which makes outdoor advertising more and more accepted and valued by people, and greatly promotes the development of outdoor advertising media. On the other hand, with the rapid development of electronic technology and software technology, embedded system development technology is more and more widely used in various fields of production and consumption. At the same time, it also promotes the speed and precision of the inkjet painting equipment to a major change. Inkjet painting equipment is a large equipment which uses spray painting technology to spray a specific picture on a special substrate. At present, the digital piezoelectric technology is the most widely used and the most advantageous one in the inkjet painting technology. In this technology, the control of nozzle is very important, which is directly related to the speed and precision of the spray painting equipment. This paper designs a kind of independent control system of the spray painting equipment relative to the data transmission, which not only improves the communication speed and efficiency of the equipment, but also increases the flexibility and usability of the equipment. The control system uses 16 / 32 bit RISC microprocessor S3C2440A as the main control processor of the inkjet equipment, and the new 78K0503D of NEC company as the control chip of the nozzle. The IIC communication is used to control the printing of high precision nozzle. This paper introduces the working principle of spray nozzle and arm processor, introduces the design framework and system composition of the control system, and introduces the design of hardware and related circuits. In the software aspect, the design definition of the control signal structure is completed, and the data transmission efficiency is improved by using the software layer and buffer queue, the communication between the main controller and the control chip is realized, and the communication flow and flow code are given. Finally, the verification platform is built, and the final results and analysis are given.
