基于CAN总线的辐射监测网与以太网接口设计

An Interface of Ethernet and Radiation Moitoring Network Based on CAN Bus

介绍了基于CAN总线的辐射监测网与以太网接口设计。系统以LPC2294作为核心处理器,DM9000以太网控制器作为以太网主控芯片构建了Ethernet和多路CAN的网关的硬件电路,将CAN总线探测到的数据通过以太网传输到主控中心进行数据图形汇总显示。

It introduces an interface between radiation monitoring network based on CAN bus and Ethernet.The system used GM pipe to detect γ ray,employed LPC2294 as the core processor.As the main control chip,Ethernet controller DM9000 constructs hardware circuit between Ethernet and multi-CAN gateway.It transmitted the data detected by CAN bus to the main control center through Ethernet for the total display of data and diagrams.
