基于RT-Thread的CAN转以太网网关的设计

Design of CAN-Ethernet Gateway Based on RT-Thread

为了解决煤矿数字安全监控系统中CAN总线网络无法与以太网直接进行数据交互的问题,结合煤矿安全监控系统的应用要求,设计了一种以STM32F107VC为控制核心,基于RT-Thread实时操作系统的嵌入式CAN转以太网网关。详细介绍了网关的硬件和软件设计,并且为了提高数据传输的可靠性和稳定性,使用了大容量的外部数据存储器。经实际测试,网关实现了CAN总线网络与以太网的互连互通,提高了安全监控系统通信的灵活性和可靠性。

In order to solve the problem that CAN bus can not exchange data with Ethernet in the coal mine digital monitoring system, an embedded CAN-Ethernet gateway is designed which takes STM32F107VC as the control core and is based on RT Thread real-time oper ating system. In the paper,the hardware and software design of the gataway are introduced. A large capacity data memory is used to im prove the stability and reliability of data transmission. The actual test results show that the gateway can implement the interconnection between CAN bus and Ethernet,and it enhances the communication＇s flexibility and reliability of the safety monitoring system.
