摘  要

 凹版印刷作為一種重要的的印刷技術(shù)，有著廣闊的應(yīng)用前景。目前，國內(nèi)主流凹版印刷機(jī)的自動(dòng)化程度低，印刷速度慢，不符合市場(chǎng)對(duì)凹版印刷機(jī)高精度印刷的要求。而隨著高性能低成本的微處理器的發(fā)展，使得設(shè)計(jì)一種高效率高精度的對(duì)版測(cè)控系統(tǒng)成為可能。
 國內(nèi)傳統(tǒng)的對(duì)版自動(dòng)檢測(cè)控制系統(tǒng)環(huán)路不穩(wěn)定，并且存在嚴(yán)重的響應(yīng)滯后性。針對(duì)這些問題，提出了一種新穎的凹版印刷機(jī)對(duì)版測(cè)控系統(tǒng)實(shí)現(xiàn)方法，即采用微處理器作為控制系統(tǒng)的核心，完成對(duì)版測(cè)控系統(tǒng)的高效率和高精度的運(yùn)作，體現(xiàn)了高性能與低成本的優(yōu)勢(shì)。該對(duì)版測(cè)控系統(tǒng)采用雙光點(diǎn)掃描頭檢測(cè)套色的誤差，誤差信號(hào)經(jīng)過濾波放大以及光電耦合后送入到微處理器，由微處理器來計(jì)算誤差糾偏量，并通過執(zhí)行電機(jī)來調(diào)整對(duì)版誤差。這不僅簡化了電路，而且提高了系統(tǒng)的穩(wěn)定性和控制的實(shí)時(shí)性，并方便了往后系統(tǒng)的升級(jí)。
 本文首先回顧了凹版印刷系統(tǒng)的技術(shù)背景，以及提出了其中存在的穩(wěn)定性和實(shí)時(shí)等套色問題。然后，提出了一種以80c196KC為核心的凹版印刷機(jī)對(duì)版控制系統(tǒng)總體結(jié)構(gòu)和控制方案，并且給出了相應(yīng)的硬件電路和程序設(shè)計(jì)框圖。最后，對(duì)系統(tǒng)的控制策略做了簡要的分析。本文設(shè)計(jì)的系統(tǒng)和其他的對(duì)版系統(tǒng)進(jìn)行比較，具有結(jié)構(gòu)簡單，調(diào)整準(zhǔn)確，響應(yīng)速度快等優(yōu)點(diǎn)，大大的提高了凹版印刷的精度和效率，具有廣闊的發(fā)展前景。

ABSTRACT

 Gravure press as an important printing technology has broad application .At present, the domestic leading gravure press machine is low degree of automation and the printing speed is slow, which isn’t satisfied to the high-precision demand of printing machine market. And as the development of high-performance microprocessors ,it is possible to design an efficient high-precision measurement and control system to the chromatography.
 The domestic traditional plate automatic detection system was not stable in the loop of control system and also a serious lag in response. To solve these problem, an original measurement and control system to chromatography is designed which use microprocessor as the core of the control system to complete the high efficient and high precision  operation. And the system has high- performance and low- cost advantage. The measurement and control system use dual-spot optical scanning machine to detect the color error, and the error signal, after the amplification and filtering ,sent into the microprocessors ,which calculate the account of error correction and drive the motor to revise the error. This not only simplifies the circuit, but also improve the system stability and real-time control and facilitate a future upgrade.
 This article first reviewed the printed technical background , as well as the issues of stability and real-time control. Then, put forward a project a which use 80C196KC as the core of the measurement and control system of chromatography, and the corresponding hardware circuit diagram and program design. Finally, brief analyze the control strategy of the system. The system in this thesis compared with other  chromatography system is more simple in structure, the adjustment is more accurate, the respond speed is faster and this system is greatly improved the accuracy and efficiency of intaglio printing.
