说明：  linux qt的移植书籍资料，Qt 是一个跨平台的C++图形用户界面应用程序框架。它提供给开发者建立图形用户界面所需的功能，广泛用于开发GUI程序，也可用于开发非GUI程序。Qt是完全面向对象的，很容易扩展，并且允许真正地组件编程。(QT is a cross platform C + + GUI application framework. It provides the functions that developers need to establish graphical user interface. It is widely used to develop GUI programs and non GUI programs. QT is fully object-oriented, easy to extend, and allows true component programming.)

说明：  光传感器采集光照数据,采集完成以后由处理器处理(photo sensor taking photo sample ,when the data is ready ,it will signal the mcpu)

IPMI 是一种可扩展的标准，它定义了如何监控硬件和传感器、控制系统部件以及记录重大事件，随着 ipmi 技术在服务器中的应用，利用 ipmi 的众多优势就成为服务器管理特别是集群管理中不可缺少的部分。本文首先介绍了 ipmi 的一些基本概念，然后给出了如何利用 ipmitool 这一工具实现 linux 系统中ipmi 管理的具体步骤和方法。(IPMItool is a utility for managing and configuring devices that support the Intelligent Platform Management Interface (IPMI) version 1.5 and version 2.0 specifications. IPMI is an open standard for monitoring, logging, recovery, inventory, and control of hardware that is implemented independent of the main CPU, BIOS, and OS. The service processor (or Baseboard Management Controller, BMC) is the brain behind platform management and its primary purpose is to handle the autonomous sensor monitoring and event logging features.)
