摘　　要：介绍了一种TCP/IP与CAN异构网络间互联网关的设计与实现方法。通过分析TCP/IP网络与CAN总线网络的特点,给出了网关硬件设计方案及软件模块。该方法采用PC外挂EPP-CAN盒子的方式,适用于任意TCP/IP网络,与一般的嵌入式网关只针对某一类计算机网络(如以太网)而扩展较难相比,具有更好的灵活性、通用性、程序可移植性和易开发易维护性。A new method of developing the gateway between TCP/IP network and CAN bus network is described. According to the features of TCP/IP and CAN, the hardware design scheme and software modules are discussed. The described method can be used in any TCP/IP network, not limited to one net type. Compared to the embedded gateway developing method, it is more flexible and general, more easily to develop and maintenance.
