Abstract


Automatic seal identification system is an important instrument of the financial industry, Founder Order, silver Inchcape has a mature seal identification systems, but these systems rely on the computer to do the algorithm processing, large volume, high cost, is not conducive to the promotion. Our laboratory according to market demand, is committed to the development of miniaturized embedded seal identification system has been developed based on DSP (Digital Signal Processor Digital Signal Processor) embedded stamp identification systems, lower cost, high integration, The only drawback is limited to the DSP weak ability to control a single operator interface, and improve the function of computer and human-machine interface can not be comparable. To compensate for DSP difficult to run most of the embedded operating system, a single man-machine interface and simple defects, proposed the use of a combination of ARM and DSP, ARM powerful control functions as the basis, combined with embedded Linux operating system and MiniGUI graphics interface, as well as a touch-screen technology, touch embedded credential authentication system and a color display, further increasing the degree of integration and functionality of the system. This study is based on already CMOS camera device for image acquisition DSP core board, the DSP model for the DM642, CMOS model MT9T001. In this study based on the ARM and DSP communication. The communication interface may both have a standard interface, which can also be a special need to customize the interface. This article compares the two methods, select a representative of the Ethernet port and DSP HPI (Host Port Interface) host interface research, and ultimately choose to use the Ethernet port for communication. Using a standard interface with simple, low-cost, fast development, should be further promoted. In hardware design, mainly to complete the design of the ARM core and expansion modules, core modules Samsung ARM chip S3C2440 64M SDRAM 32M NAND Flash, expanded 24-bit color LCD touch screen module, Ethernet, USB, serial port and so on, and in accordance with the DM642 HPI interface manual designed HPI interface on ARM. The acquisition device DM642 MT9T001. Debugging, so that the normal work of the ARM board, and with the DSP through the Ethernet port to establish a connection based on the TCP / IP protocol. Software design, by comparing the use of open source embedded Linux as the operating system of the ARM, on the development of a simple HPI driver, transplantation Feynman Software's MiniGUI 1.3.3 as a graphical interface, developed based on MiniGUI touch and display interface. Finally, integration testing, the system can use the touch screen control system, click the button on the interface can be controlled CMOS camera to capture images or DSP processing image through a window after viewing the collection or processing image. Recognition algorithm is not the focus of this article, the system software reserved recognition algorithm interface for easy upgrades and updates of the algorithm.
