| 摘 要： | 磁悬浮列车的多路串行异步通信系统,在DSP并行总线上扩展UART芯片,采用RS-485总线串行通信,并以硬件实现异步数据传输.系统软件设计包括ADMC401及STl6C554的初始化程序和通信协议等,其初始化负责设置操作每个通道所需参数.而悬浮间隙传感器和控制器间则采用半双工方式工作.

| Abstract: | The multi serial asynchronous communication system in maglev vehicle extended UART chip in DSP parallel bus,adopted RS-485 bus for serial communication and realized asynchronous data transmission by using hardware.The software design of system includes the initial program of ADMC401 and ST16C554 and communication protocol,etc.Parameters of each channel were set up by initialization.The semi-duplex work form was adopted between suspending gap sensor and controller. |
