使用USB介面來建立智慧型居家環境之探討
Study of USB Interface Based Smart Home Systems
摘要
追求舒適、人性化的居家環境，一直是現代科技努力的目標之一。隨著科技的發展，「智慧居家環境（Smart Home）」，已經不再是遙不可及的情景，使其擁有自動化、安全性以及娛樂性等相關功能。欲實現智慧型居家環境，首先須建構一智慧型居家環境網絡，而目前常見的環境網路建構以TCP/IP和紅外線為主。而隨著USB介面以受到重視及應用，幾乎所有的PC周邊設備，以及消費型電子產品皆已USB介面列為必備的介面。本文中首先會介紹USB的結構和特點包括排線特徵、相關協定、傳輸方式等等，來對USB做整體的認識。接下來會討論USB系統的一般開發方法分為設備端硬體、設備端韌體、主機端驅動程式和主機端應用軟體三個部分。然後論文會詳細介紹USB設備的硬體和軟體開發的技術細節包括USB設備開發平台、USB設備韌體設計和主機端程式開發，而USB設備協議的編寫方法同時也會討論在Windows XP下開發使用端應用程式的一般方法。最後則是探討以USB介面來架構建立一智慧型居家環境網路評估，分析此架構以不同的傳輸模式及端點的配置下，評估其效能以及提出未來可改善的方法來降低系統對USB周邊設備的延遲性。

Digital home has been a promising research area in recent years. Owing to the development of more personalized equipment in digital home, it has been rephrased as Smart House or Smart Home in recent years. It is natural that consumers want to have a easy way of creating, using, managing, and sharing the digital contents or information. But, the capability of digital home equipment will become more and more complicated. It is our attempt to bridge the gap between these two ends. Up to present, most of smart home networks still use “TCP/IP” or infrared interface to build the smart home network. As the USB interface has been paid much attention to and put in use day by day, almost all peripheral equipment of PCs and consuming electric products have gradually consider USB as a necessary attachment. The thesis first describes the architecture and features of USB, including the bus attributes, the protocol definition, types of transactions, and so on. After that, the thesis will talk about how to develop the USB system, including device hardware, device firmware, host driver and host software. Then the thesis describes some development and technique details of the hardware and software design of a device and the host, including how to write USB device protocol stack, and talk about the kernel drivers and user programs in Windows XP. Finally, we will consider the USB interface configuration to develop the smart home device, analyze different transfer types and endpoints of this structure.
