Study And Implementation On Data Acquisition Terminal For Discrete Manufacturing

Manufacturing Execution System (MES) has become the key elements in the discrete manufacturing information solutions, but the production on-site data acquisition system's shortcomings, especially the data acquisition terminal can not meet the current coorporate face of increasing fierce competition, production and manufacturing model are from a single production model for the stock shift to order, small-volume,multi-species status of agile manufacturing. Although the bar tab, wireless IC card, RFID and other semi-automatic information collection technology for the production of discrete manufacturing workshop, but for discrete manufacturing mainly for rough or semi-finished products, so it does't convenient to paste the bar tab on materials.Also thers is one be based on electronic billboards data acquisition system model, but it is more adapted to high-volume production and processing plant.This paper based on the overall of the discrete manufacturing workshop Data-acquisition, from the technical implementation, cost control, as well as practical value point of view focuses on how to develop a Data-acquisition terminal that fit to order, small quantity and variety of discrete agile manufacturing processing field. To build the Data-acquisition terminal hardware main reference Samsung's S3C2410 development platform, the software system is mainly based on the open-source, for example U-Boot bootloader, Linux operating system and MiniGUI graphics libraries.This thesis introduces the design of hardware platform and porting plan of software in hand port. This thesis researches the theory of the leading program, the key point in developing drive device. Based on those researches above, this thesis analyzes and achieves the transplanting process of U-Boot 1.1.4, the development of drive of device in CC2420 wireless receive chip, GPIO device,LCD device,ethernet device and key device,etc,and also builds a file system based on the characters of the target system. And it introduces the elements of the development of GUI based on MiniGUI. With the application of MiniGUI, has developed a hand-held data acquisition terminals that has a preliminary graphical man-machine interface.
