CAN/MOST网关的设计与实现

Design and Implementation of CAN/MOST Gateway

为解决车载CAN(Controller Area Network)网络和MOST(Media Oriented Systems Transport)网络间的数据共享问题,提出了一种CAN/MOST网关的设计方案。通过分析两种网络的网络模型,构建了CAN网络和MOST网络互联的核心技术——CAN/MOST网关的系统结构,并在此结构的基础上实现了基于单片机89S51的网关的硬件设计和软件流程。该网关完成了CAN网络和MOST网络的互联,使不同的车载网络设备能共享数据。

In order to handle the data sharing problem between in-vehicle CAN （Controller Area Network） and MOST （Media Oriented Systems Transport） network, a design of CAN/MOST gateway is proposed. By analyzing the models of CAN and MOST networks, the key technique that interconnects CAN and MOST networks is con- structed to design the architecture of CAN/MOST gateway. Based on this architecture, the design of hardware that used microcontroller 89S51 and the flow chart of software are implemented. The interconnection between CAN and MOST has been achieved by CAN/MOST gateway which can share data between in-vehicle equipment. It is very important to the integration process of in-vehicle bus network.
