Design And Implementation Of Sea Cucumber Grade Automatic Selecting System

The technology and output of sea cucumber industry are developed rapidly. After the pre-processing, sea cucumber requires to be graded. Because manual grading has some drawbacks such as low efficiency, poor accuracy, fatigue and unhygienic characters, it can't meet the normal requirements of sea cucumber grading. Sea cucumber grading machine is an automatic equipment with a combination of weights and images, which can effectively overcome the drawbacks of manual grading, and complete the task efficiently and accurately.Sea cucumber grading machine with Exynos4412 processor core, using embedded Linux system, collects sea cucumber mainly according to its weight and image- Unlike other grading machines in the market, our design of sea cucumber machine is equipped with image identification, which can effectively prevent inaccurate weighting issues caused by quantity and foreign material. The designed grading machine is also available for other products. We mainly complete the designs of the hardware, software and graphical user interface of the grading machine in this paper.The hardware consists of the design of the circuit around core board; image capture circuit; selecting control circuit; conveyor speed control circuit and touch screen interface circuit. Software mainly includes the design of device driver, user interface and application. Device Driver incorporates the design of TVP5150 driver and selecting controller driver; The design of application includes the design of image acquisition program; image recognition program; classification data handler. Graphical user interface is used for parameter settings of the machine, including:the main window; selecting criterion setting module; time and speed setting module; serial port parameters setting module; network parameter setting module; blow testing and password settings, and other module design.The GUI of Sea cucumber selection machine is based on Qt/E-4.7.3. The application is designed and developed completely on Windows. After debugging, the application runs on the embedded Linux system by cross-compiling. Hardware and software of the sea cucumber selection machine system are designed and accomplished. After being tested repeatedly and conducted numerous experiments, it can complete the cucumber grading task efficiently.
