摘　　要：在某武器系统中,需要完成网口和4个串口的数据转换,研制了多串口与以太网的转换装置,硬件采用ARM-11平台的三星处理器S3C6410开发,系统通信遵守modbus协议,网络侧采用UDP协议,在Linux环境下,实现了4个串口与网络的数据传输,当网络中断时,会自动的进行武器前端的查询任务,实现数据FLASH存储,当网络正常时,能从FLASH中读取数据并返回。系统在实际系统中进行了测试,并给出了测试结果。In a weapon system, an interface between Ethernet and four serial port is needed, so a transfer device is developed. The hardware is based on ARM-11 named S3C6410, and modbus protocol is employed, UDP is adopted in net. Under the Linux operation system, data transfer between serial ports and Ethernet is achieved, especially, when net is broken, system can check the weapon, and then saves the data in Nand-Flash. When net is connected, system can reads the data from Nand-Flash, and send it to control center. System testing results are also demonstrated in detail.
