基于SC28L198的多串口服务器设计

Design of Multiple Serial Port Network Gateway Based on SC28L198

针对许多设备不具备网络接口的问题,以ARM7 Cortex-M3处理器LM8962为核心构建嵌入式系统,利用SC28L198芯片扩展8个串口,完成基于μC/OS-II操作系统和TCP/IP协议的多串口服务器设计。该系统能够同时为8个串口设备提供以太网远程数据传输,为具有串行通信接口设备的网络控制提供了条件,实现了计算机远程监控。

Many types of equipment do not have network interface.The goal of this thesis is to solve the access to this kind of equipment.The embedded system constructed on basis of ARM7 Coxtex-M3 MCU LM8962 and 8-channel UART was expanded by SC28L198.The multi-serial port device through TCP/IP protocol was developed under μC/OS-II operation system.The system can provide remote data via Ethernet for eight serial devices simultaneously,which provides conditions for the devices with the serial communication interface in the network control and realizes the capability of computer remote monitoring.
