中文摘要: 随着光驱接口的升级和蓝光技术的发展，对光盘库的主控系统提出了新的设计需求。主要阐述主控板的设计，将光驱的数据通道和控制通道相分离，主控板通过向马达板发送命令，达到控制光驱的目的。主控板接收以太网数据包，将其解析成马达板命令，控制整个光盘库。本系统使用基于ARM920T 架构的S3C2440 微处理器，移植嵌入式Linux，提高开发效率，具有很强的可移植性。经验证，该主控系统完全满足系统的应用需求。
Abstract:As the development of drive's interface and Blu-ray, the main control system has new requirements. This
paper is about the design of the main controller. The data bus and control bus of the drive are separate. The main
controller is able to control the drives by sending commands to motor board. The main board receives packets from
Ethernet, and converts them to Uart commands of the motor board to control all of the optical disc library. The main
controller is at the core of embedded microcontroller S3C2440 based on ARM920T architecture, and transplants
embedded Linux which can help to improve development efficiency and portability. It is certified that the main
controller meets the requirement in practice.
