摘  要   
 
現場總線在控制系統中的應用使各領域的綜合自動化控制技術飛速發展, 成為控制領域的一個新熱點。控制器局部網（CAN,controller area network）, 屬于現場總線的范疇, 因為其卓越的特性、極高的可靠性和獨特的設計, 已經成為國際標準, 在工業自動化設備的互連方面得到越來越廣泛的應用, 并已被公認為最有前途的現場總線之一。
本文詳細介紹了CAN總線通信在智能家居中的設計方案，詳細說明了該方案的設計思想，并闡述了其功能，特點。本文的設計緊緊圍繞以智能家居為應用目標，利用CAN總線實現智能家居的通信，使得原來不具有CAN功能的處理器實現高速的CAN總線通信。具體的設計用ARM芯片S3C2410為核心，因為S3C2410并不帶CAN控制器，所以選用MCP2510做為CAN的控制器，并且以SPI接口做通道，軟件部分以模塊化設計為中心，將待開發的軟件系統劃分為若干個相互獨立的模塊，這樣使完成每一個模塊的工作變得明確。硬件部分的設計按照CAN典型的設計方法來設計，嚴格按照各芯片引腳的參數進行設計。
    從實驗的結果可以看出，該設計可以實現了CAN的通信功能，實現了數據的自發自收。

Abstract

   In the application of controlled systems, Fieldbus has improved the development of the comprehensive controlled technique,which has been a hot topic in the field of control .Controller Area Network belongs to the category of the Fieldbus.Due to its transcendent characters,the fantastic reliability and the special design,CAN has reached the international standard and been applied more and more popular in the aspects of interconnectiong of the industry automation device.Moreover,it’s regarded as one of the most promising Fieldbus by the public.
This article introduced the design program of CAN correspondence in the Intelligent House.At the same time,this paper declared the design thought of this program carefully with its function and characters.The design of this article focused on the Intelligent House as the applied goal,then fulfilling the correspondence of Intelligent House by the CAN fieldbus.So that the controller without CAN function at the begine can fulfill the correspondence of the CAN Fieldbus rapidly.The specific design regarded the ARN chip S3C2410 as the core of the whole design.Because S3C2410 had not CAN controller,so I choosed MCP2510 as CAN controller and the SPI interface as channel.The software of this design was mainly about modular design .In order to clera the task of each module,I devided the undeveloped software system into several separate module.The hardware of this design was designed in terms of the tipical CAN design and the parameters of each chip pin strictly.
 We can see from the result of this experiment ,the design can fulfill the correspondence function of CAN so that the data can be sended and received by itself.
