近代汽車MOST 與 CAN 網路介面之整合

Abstract

本論文主要在探討一種為汽車產業開發的多媒體網路技術--MOST (Media Oriented System Transport，多媒體導向系統傳輸)，和汽車網路CAN(Controller Area Network)。我們將示範其多媒體應用及資料傳輸控制介面的應用，共利用OASIS SiliconSystems公司所提供的MOST網路服務應用程式介面 (MOST NetServices API)，來撰寫程式去控制在MOST網路上的多媒體設備，例如DVD播放器、收音機、IPod Gateway及聲音放大器。在應用中，我們將個人電腦主機當作網路的中控台，透過MOST網路介面卡 (MOST PCI Board)或光纖網路分析介面盒 (Optolyzer Interface Box)及USBCAN2分析工具，來建立MOST網路與CAN網路和個人電腦主機之間的通訊。藉由各種多媒體應用之介紹及SAAB 95 SID的應用，說明MOST網路服務應用程式介面的使用方式及USBCAN2的使用方法；在最後，我們設計了一個可同時控制MOST與CAN網路的程式介面，來實現在MOST網路應用下的影音伺服器及CAN網路下的設備操作。

The main purpose of this thesis is to explore and demonstrate CAN(Controller Area Network) and the multimedia applications under MOST (Media Oriented System Transport) network which is originally developed for the automotive industry. With the MOST NetServices API provided by OASIS SiliconSystems, we can build programs to control multimedia devices for MOST, such the DVD Player, Radio Tuner, IPod Gateway and Audio Amplifier. Besides, both the MOST PCI Board and the Optolyzer Interface Box and USBCAN2 are used for establishing the communication between the MOST network, CAN network and a PC which serves as a control central for the network. The details of understanding the NetServices API under MOST network is explained through different multimedia applications. The understanding of USBCAN2 is explained through demonstrating SAAB 95 SID. We show the application of USBCAN2 device by demonstrating SAAB 95 SID. In addition to the ordinary MOST and CAN applications, a new Audio/Video server interface under MOST network is also designed.
