| 摘 要： | 根据铁路车号自动识别的基本原理,采用ARM9工业级芯片AT91SAM9260设计开发了铁路车号识别系统的嵌入式系统;嵌入式系统通过串口与射频模块和车轮传感器之间通信,通过串口或以太网口与CPS之间的通信。通过状态转移图说明了铁路车号自动识别系统的待机状态、车号识别、数据传输以及自检状态的转换关系;通过系统的状态及工作流程建立了系统的流程图。为了识别处理不同模块的收发数据,通过程序详细说明了在接收数据中添加端口模块编号字节的方法。

| Abstract: | The train identification system based on embedded system is designed with ARM9 RSIC CPU AT91SAM9260 under the principle of automatic train identification system. The embedded system communicates with RFID module and train wheel sensor by serial ports. The embedded system communicates with CPS by serial port or Ethernet port. There are idle state, tag identification state, data transmission state and self-test state in the system. The state transition relation is introduced with state transition chart The fl... |
