[Abstract]:In this paper, the basic concepts and application status of PACS system are introduced, and the future development of PACS system technology is prospected by analyzing the technical development and future demand of PACS system. It is of great significance to develop domestic PACS system with high performance, low cost and independent copyright. The second part introduces the embedded system and its development status, describes the embedded hardware and embedded operating system in detail, and understands the working principle and main functions of the mainstream embedded hardware and embedded operating system. On the basis of the analysis and comparison of various embedded operating systems, it is found that Linux system has very reliable stability and wide compatibility, which is the most ideal choice for the development of this embedded system. In the third part, the hardware development platform and software control system are determined and the embedded development platform is built. The S3C2410 development board of Samsung Company is chosen as the hardware platform and Linux 2.6 kernel as the embedded operating system kernel. The software platform is transplanted on the basis of analyzing the principle of embedded Linux operating system. The fourth part is the realization of wireless PACS terminal. Firstly, the principle of USB protocol in Linux system is analyzed, then the realization method of USB wireless card driver is studied and the wireless card driver is transplanted. On the basis of deeply studying the working mechanism of embedded graphical user interface, the embedded graphical user interface is transplanted. Finally, the overall framework of wireless PACS system and the terminal software of wireless PACS are designed, and the terminal software is realized.
