[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.
