【摘要】：本課題針對(duì)醫(yī)療行業(yè)中藥液霧化所需的劑量控制功能,利用DOE(試驗(yàn)設(shè)計(jì))技術(shù),以研究設(shè)計(jì)一套響應(yīng)快速、霧化穩(wěn)定、控制精度優(yōu)良的霧化控制系統(tǒng)為目標(biāo)。在Minitab軟件平臺(tái)上,對(duì)采集到的試驗(yàn)數(shù)據(jù)進(jìn)行分析,建立數(shù)學(xué)模型進(jìn)行參數(shù)優(yōu)化,找出系統(tǒng)設(shè)計(jì)參數(shù)的最優(yōu)解,從而提高霧化控制系統(tǒng)的準(zhǔn)確性、穩(wěn)定性以及可靠性,實(shí)現(xiàn)藥液霧化劑量的控制。本文的主要工作有以下三個(gè)方面:首先針對(duì)霧化控制系統(tǒng)的特點(diǎn),搭建試驗(yàn)平臺(tái),編寫(xiě)Lab VIEW控制程序。利用全因子試驗(yàn),分析了影響霧化控制系統(tǒng)各因子的顯著性,區(qū)分出顯著性因子和非顯著性因子。在此基礎(chǔ)上,利用響應(yīng)曲面設(shè)計(jì)試驗(yàn),通過(guò)分析試驗(yàn)數(shù)據(jù)建立了霧化量和霧化量均勻性的數(shù)學(xué)模型,并對(duì)試驗(yàn)因子進(jìn)行優(yōu)化分析,從而得到試驗(yàn)因子的最優(yōu)參數(shù)組合,使霧化量在目標(biāo)值范圍內(nèi),霧化量的離散程度最小,抗干擾能力最好。其次通過(guò)試驗(yàn)對(duì)上述試驗(yàn)設(shè)計(jì)得到的最優(yōu)參數(shù)組合進(jìn)行考察,試驗(yàn)結(jié)果表明在該參數(shù)組合條件下,霧化量滿足目標(biāo)要求。最后使用上述最優(yōu)參數(shù)組合作為霧化控制系統(tǒng)的設(shè)計(jì)參數(shù),設(shè)計(jì)制作了一套霧化控制系統(tǒng)。該系統(tǒng)包括有硬件設(shè)計(jì)和軟件設(shè)計(jì)兩部分,硬件設(shè)計(jì)又可分為霧化裝置設(shè)計(jì)和控制電路設(shè)計(jì)兩部分,軟件設(shè)計(jì)采用了C語(yǔ)言編寫(xiě)控制程序,從而實(shí)現(xiàn)了對(duì)霧化系統(tǒng)的控制。通過(guò)對(duì)該系統(tǒng)進(jìn)行測(cè)試試驗(yàn),結(jié)果表明該系統(tǒng)的霧化量達(dá)到了預(yù)定要求,所設(shè)計(jì)的霧化控制系統(tǒng)具有較好的準(zhǔn)確性和穩(wěn)定性。
[Abstract]:Aiming at the dose-control function of liquid atomization in medical industry, the purpose of this paper is to study and design a set of atomization control system with fast response, stable atomization and good control precision by using DOEtechnology.Based on the Minitab software platform, the experimental data collected are analyzed, the mathematical model is established to optimize the parameters, the optimal solution of the system design parameters is found, and the accuracy, stability and reliability of the atomization control system are improved.The control of the atomization dose of the liquid was realized.The main work of this paper is as follows: firstly, according to the characteristics of atomization control system, the test platform is built and the Lab VIEW control program is written.The significance of the factors affecting the atomization control system was analyzed by using the full factor test, and the significant factors and the non-significant factors were distinguished.On the basis of this, the mathematical model of atomization quantity and atomization uniformity is established by analyzing the test data, and the optimum parameter combination of the test factor is obtained by optimizing the test factor.The dispersion of atomization amount is the smallest and the anti-interference ability is the best in the target range.The experimental results show that the atomization quantity can meet the requirements of the target under the condition of the above experimental design.Finally, the above optimal parameter combination is used as the design parameter of the atomization control system, and a set of atomization control system is designed and manufactured.The system includes two parts: hardware design and software design. The hardware design can be divided into two parts: atomization device design and control circuit design.The test results show that the atomization quantity of the system is up to the predetermined requirement and the designed atomization control system has good accuracy and stability.
