摘　　要：CAN总线作为一种优秀的现场总线已成为构建现代监测网络的重要通信平台之一,而作为各设备之间通信桥梁的接口卡,显得更为重要。本文介绍一种基于CAN总线的智能接口卡的设计方法,给出了一个利用PHILIP公司的CAN器件实现的接口卡原理框图,并阐述了接口卡程序的编制方法。As an excellent Field bus,Can bus has become the major communication platform to construct the modern network for monitor.The interface card will be more crucial ,for we use it to connect the communication equipments. In this paper ,we introduced a designing method for CAN Bus interface of the front module in a field network based on the CAN bus technology.We also introduced a instance adopting the PHILIPS ' s CAN interface products.The method for related programming is enclosed,too.
