摘要
针对无人机数据链地面控制站监控计算机与多种部件串行通信的复杂问题,提出了以嵌入式系统来实现多串口到以太网数据转换网关的设计方案。给出了利用LPC2388并行数据口实现串口扩展的方法。详细介绍了硬件结构设计和软件设计,并且给出了数据流的分析。该方法在解决了实际的工程问题的同时也为传统串口设备通过标准TCP/IP协议接入Internet提供了一种低成本解决方案。
Aiming at complex communication between UAV data chain ground control station monitoring com- puter and serial parts, one design which can realize serial ports to Ethernet conversion gateway based on embedded system is proposed. The expansion method of parallel data port of LPC2388 to serial port is given. The design of hardware structural and software is introduced in detail, furthermore an analysis of data streams is given, as well as provided a low-cost for traditional serial devices through a standard TCP/IP protocol access to Internet.
