【摘要】：隨著醫(yī)療技術的發(fā)展,血型分析作為臨床輸血的必須檢驗項目,需要處理的樣本量在急劇增加,傳統(tǒng)的手工檢測方法已經無法滿足新時代血液分析工作的要求,對于全自動血液分析系統(tǒng)——微柱凝膠檢測一體機的研制需求迫在眉睫。微柱凝膠檢測一體機通過對微柱凝膠卡的離心來進行血型分析實驗,可以有效地提高血型分析的標準化和準確率,大大減少對人力資源的浪費,研究高速度、高準確率的微柱凝膠檢測一體機具有十分重要的意義。 根據微柱凝膠檢測一體機所需的功能,本文設計了一套基于PLC的微柱凝膠檢測一體系統(tǒng),能夠集裝夾微柱凝膠卡,判定有效性,離心和對離心結果進行判讀等一系列動作于一身,代替人工完成對微柱凝膠卡的一系列操作,并用電子判讀取代人工判讀提高了判讀標準化,降低了人力的使用。論文的主要研究內容有以下方面：①通過調研和分析,根據微柱凝膠檢測一體機的功能需求,制定了微柱凝膠檢測一體機的總體設計方案,詳細分析了其工作原理和工作流程,確定了微柱凝膠檢測一體機的性能指標。②完成了卡盒系統(tǒng)、抓取系統(tǒng)和離心系統(tǒng)等機械部件的設計,并完成了相應的三維建模,通過有關計算和有限元分析論證了設計的可靠性。③完成了微柱凝膠檢測一體機控制部分的設計,結合PLC理論,完成相關硬件和軟件設計,主要包括控制方案選擇和實施、PLC程序設計、人機交互界面的設計等。④對微柱凝膠卡的圖像識別技術進行了說明,通過分析微柱凝膠檢測結果的識別標準,研制出了一套完整的判讀方法,通過圖像裁剪、圖像分割、灰度處理、平滑濾波、縱向投影和曲線判讀等一系列流程對離心結果進行快速準確的判讀。 經過安裝調試,微柱凝膠檢測一體機已投入使用,并能夠完成相應的實驗項目。
[Abstract]:With the development of medical technology, blood type analysis, as a necessary test item of clinical blood transfusion, needs to be dealt with in a sharp increase in sample size, traditional manual testing methods can no longer meet the requirements of the new era of blood analysis work.For the automatic blood analysis system-micro-column gel detection machine development is urgent.By centrifuging the microcolumn gel card for blood type analysis, the microcolumn gel detector can effectively improve the standardization and accuracy of blood group analysis, greatly reduce the waste of human resources, and study at a high speed.The high accuracy microcolumn gel detection machine has very important significance.According to the function needed by the integrated microcolumn gel detection machine, a microcolumn gel detection system based on PLC is designed in this paper, which can assemble the microcolumn gel card and determine the validity.A series of actions, such as centrifugation and interpretation of centrifuge results, are used to replace manual operation of microcolumn gel card, and electronic interpretation instead of manual interpretation improves the standardization of interpretation and reduces the use of manpower.The main research contents of this paper are as follows: 1 through investigation and analysis, according to the functional requirements of microcolumn gel detection integrated machine, the overall design scheme of microcolumn gel detection integrated machine is formulated, and its working principle and work flow are analyzed in detail.The performance index of microcolumn gel detection integrated machine was determined. 2. The design of mechanical parts such as card box system, grab system and centrifuge system was completed, and the corresponding 3D modeling was completed.Through the calculation and finite element analysis, the reliability of the design is demonstrated. 3. The control part of the microcolumn gel detection integrated machine is designed. Combined with the PLC theory, the related hardware and software are designed.This paper mainly includes the selection of control scheme and the implementation of PLC program design, the design of man-machine interface and so on. 4. The image recognition technology of microcolumn gel card is explained, and the recognition standard of microcolumn gel detection result is analyzed.A complete interpretation method is developed. The centrifuge results are interpreted quickly and accurately by a series of processes such as image clipping, image segmentation, gray processing, smoothing filtering, longitudinal projection and curve interpretation.After installation and debugging, microcolumn gel detection machine has been put into use, and can complete the corresponding experimental project.
