摘要
基于Cortex ARM处理器STM32开发了一种串口服务器系统。分析了串口服务器的主要构成及工作原理,提出了采用主控芯片控制以太网控制芯片W5200的解决方案;设计了系统的具体硬件电路;完成了串口服务器的程序设计,可选择TCP Server、TCP Client和UDP等工作方式;基于C#.Net技术,开发了上位机参数设置工具软件。经实验测试,不同波特率下均无丢包现象,串口波特率最高支持256000bps,稳定可靠。该串口服务器已成功应用于灌区闸门以太网方式组网,实现远程调水控制。
A serial device server based on STM32 was presented. The main component part and operational principle of server was analyzed. The solution of main control chip and Ethernet control chip W5200 was proposed. The specific hardware circuit of system was designed. The software which can set TCP Server,TCP Client and UDP working mode was accomplished. The PC software of parameter- setting tool based on C#. Net was developed. The experiment demonstrates that there was no packet loss under different baud rate,and the server can support baud rate of 256000 bps with stable performance. The erial device server has been successfully applied by Ethernet network of sluice gate in irrigation district,implementing long- distance control.
