摘　　要：针对多类型核辐射数据采集系统中串行数据传输能力不能满足环境实时监测需求的现状,设计了多串口转以太网辐射数据传输系统。系统以ARM架构STM32F407处理器为核心,为接收不同辐射数据的串口分配队列缓冲区,将轻量级LwIP协议栈优化后移植到系统平台上,轮询读取出串口缓冲区中辐射数据并进行标识封装,将封装好的串口帧作为LwIP协议栈中应用层数据,最终实现了多个串口与单个网口双向传输的数据传输系统。经测试,其传输性能优于同等条件下RS232的数据传输,满足了设计的需求。Aiming at the current situation that the serial data transmission capability of multi⁃type nuclear radiation data ac⁃quisition system cannot meet the requirement of environment real⁃time monitoring,the multi⁃serial port to Ethernet radiation data transmission system was designed and implemented.System takes the ARM architecture STM32F407 processor as the core,the se⁃rial port receives different radiation data distribution queue buffer,the lightweight LwIP protocol stack is optimized after transplan⁃ted into system platform,polling read out a serial port radiation data in the buffer and identified encapsulation,is good to a serial port frame as LwIP protocol stack application layer data,finally achieves multiple serial ports with individual so bidirectional data transmission system.Through testing,its transmission performance is better than RS232 data transmission under the same condi⁃tion,and meets the design requirements.
