Testing of Pharmaceutical Tablet Strip

testing of Pharmaceutical launch bea StripCAREER EPISODE 11.1 in orgasmI fulfild my Bachelors degree in electronics and communication engineer in the year 2011. I pursed my engineering from Vyas Institute of Engineering and Technology, Jodhpur, India. During my final semester of engineering I had to make a landing model in the issue of electronics. I came up with a project called Testing of Pharmaceutical Tablet denude. The project was performed in group of three. It was completed under the direction and animation of Er. Yogesh Chaudhary. In my first c areer episode, I have described the melt done by me in this project in detail.1.2 BACKGROUND unavoidableness of medicines and its merchandiseion is increasing rapidly. There are possible occurrences of break of serve, picks in the abridgment or sidestep while its production. And when these alter oral contraceptives are consumed, it may stupefy irritation or side effects to otherwise body whiles. To contemplate the production, it becomes very tough manually but the same task sens be achieved with the dish of jut physical processing by automation of visual inspection. My project deals with the identification of the damaged products after its manufacturing. It involves series of task manage segmentation, video processing, filtration, subtraction, pixel-calculation, de-noising, thresholding, and region based statics to identify the damaged and disordered domiciliations.1.3The base moto behind my project is to identify and filter out the damaged and spoilt capsule strips. Missing tablet, color, or shape/size difference in the midst of a set of tablets, or every crack or breakage in the tablets go a sort be identified and marked as stain through my project. The idea was to reduce the manual work for identification of the damaged tablets as the job quarter be tedious. And to introduce a in the altogether occasion that would contribute in digital technology and for the welfare of the society. realization of defective tablets is done with the do of date processing that go fors various techniques of algorithmic rule for processing all the digital emblems.1.4Image processing works on the technique that uses features like extraction, pattern recognition, edge detection and template matching. This process manipulates the data faster to achieve the desired result. For quality assurance of the products that are being manufactured majorly require automation of visual inspection. In this technique, a morphological operation such as opening operation is utilise for finding defects. The image is made fit for the further processing by performing image segmentation on the input image and past it is filtered to remove whatsoever noise. By inscribing rectangles subtraction is performed on the image with the help of morphological operations and it is also subtracted from original gray image which shows the broken tablets.For calculating the exact location of the br oken tablet, pseudo coloring system is used and the pixel of the broken capsule is calculated. Correct size or color and any cracks are detected by performing ecological niche detection and Harris algorithm technique on the tablets. Which is then followed by around pre-processing. After detecting the corners, they are compared with the template image and if there is any mismatch in the feature with the original template and the test image, the tablet gets rejected otherwise it is accept and given for use.1.5Me being the team leader, had to work out the flow and plan on how to proceed with the capital punishment process. I divided the project into small tasks and gave priority to each of them. Then they were depute the duration in which that task had to be completed. My major task was intent the circuit diagram and block diagram on which the components could be decided. And the other crucial task was software coding. Regular meetings were kept with my team span and the projec t guide to get any suggestions for any improvement in the project. Meetings were either through email or small presentations had to be made.1.6 personalised ENGINEERING ACTIVITYI started off with surveying the market so that the project I make would be useful. I read papers and articles relating the new upcoming technology and tried to do research on image processing methods and its adept specifications. This helped me to learn and build new technical skills. By applying my engineering knowledge and through technical reading I plotted a block diagram and decided upon the main computer ironware components that could be used for this project.It involvedElectrical components like Power put out of 230V, contractor 220-240V 1.47A, conveyor crash, step down transformer and DC get.Electronics components such as a microcontroller, LCD, Regulator IC, relay.And a basic camera of 1.3MP/VGAWith the help of the hardware components and block diagram I used a PCB endeavoring bastard for d esigning and structuring my circuit diagram.1.7After deciding and finalizing of the components, I wrote down the procedure in which the tracking of the missing tablet or damaged table would be done. The camera was used basically to get the complete image of the production. After getting the image, it is converted to monochrome image from RGB one. This results in the pomp of the tablet strips in black and white form, where the strips will be seen in grey color and the tablets would be in black. A predefined number is depute and kept for the tablets in a strip to keep the track of it. If the tablets are embed to be lower than the defined number after image processing takes place, the microcontroller will signal the second motor to discard the strip detected. This was the logical that was used for finding the tablet strip with missing tablet.1.8In the similar fashion a procedure was implied for detecting and finding cracks in the tablets. For that, firstly all other components are r emoved from the image and scarcely the tablet is seen. This is done through filtration technique of image processing. After this the image is converted to black and white from the original RGB image. Because of such design and method, altogether cracks could be seen in the image if there are any. They would differ in color from the black tablet. They would appear to be white thin or thick lines. So, by applying such functioning technique, the presence of any crack in the tablet could be traced.1.9The working of my model is very simple. above two logics are converted into a programming code through two software Bascom AVR and MATLAB 2013, and then the code is installed in the microcontroller ATmega16. Working with MATLAB software was not difficult and coding was not an issue because of having a work of image processing in my curriculum. When the system is powered on with the help of power supply section, the conveyor belt starts to move. When the camera lens committed to the sys tem senses the tablet strip that is passed through the conveyor belt, it would signal the microcontroller to interference the belt that runs with the help of motor 1. This is done for analyzing the tablet strip. ADC is used for converting the analogue power signal from sensors to digital form for signaling the microcontroller.The image taken of the tablet strip is scanned and analyzed accordingS1 to the functions as designed in MATLAB code. It will check for any defects or cracks or any missing tablet from the strip with the help of the image that was taken through camera. Based on the quality check performed using image enhancement and by carrying out morphological operations in MATLAB, it would signal the microcontroller to start the conveyor belt if no defect is found and in situations of faulty tablet motor 2 is signal to run a rejecting mechanism. A LCD is connected to get the count of number of strips checked, rejected or for the ones that are found defective. USART is used for communicating with the PC through microcontroller and vice-versa.1.10In the end, I could complete the project on time. The most difficult part of my project was to design and propose the circuit diagram. As working with PCB designing software was tout ensemble new for me. It took several trials sooner coming on the final figure. And implementation of the hardware was tough. Few minor mistakes created led into a big line of work in my end mistake. I de-soldered the wrongly connected component part and connected it in the proper way to get the desired take and the circuit running. At the last stage, a test run was performed before submitted to check the working of each component and to see that the expected issue is achieved. Working in teams was a challenging task as coming on one mutually agreed statement and solution is quite difficult. Though I managed my team well and never made any unfair decisions.1.11 SUMMARYThus, for companies manufacturing number of tablets in a da y, inspecting the final product manually can be tiresome and a tedious job. The confederacy need the help of automated systems. So, my project is an economical and efficient way to solve this problem. They only problem with this system is that it cannot be used for logical tablet strips and is made to use for single colored tablets. This problem can be solved by performing further expansion on my project.By performing this project, I learnt a way in which the image processing technique is applied. It was a great learning experience. I could use my engineering knowledge and use it to apply theoretical knowledge into hard-nosed grounds. While conducting surveys, I could understand the market position and market pass judgment of new technologies. It gave me a good exposure.S1
