摘　　要：目前提出的嵌入式计算机远程辅助教学系统辅助范围有限,辅助时间较长。为此文中基于Web技术设计一种新的嵌入式计算机远程辅助教学系统。系统硬件由存储器、中央处理器、输入设备和输出设备组成,存储器包括教师端存储器与学生端存储器,中央处理器主要有逻辑单元(ALU)、控制单元、输入/输出单元三部分。软件分别设计Web服务器程序和数据库程序。为验证教学系统的有效性,设计对比实验,结果表明,基于Web技术设计的嵌入式计算机远程辅助教学系统能够有效扩大辅助范围,缩短辅助时间。The currently⁃proposed embedded computer remote auxiliary teaching system has limited auxiliary scope and long auxiliary time.A new embedded computer remote auxiliary teaching system based on Web technology is designed.The system hardware is composed of memory,central processing unit,input device and output device.The memory includes teacher⁃side memory and student⁃side memory.The central processing unit has three parts:arithmetic logic unit(ALU),control unit,and I/O unit.In the software part,Web server program and database program are designed respectively.In order to verify the effectiveness of the teaching system,a comparative experiment was designed.The results show that a new embedded computer remote auxiliary teaching system based on Web technology can effectively expand the scope of assistance and shorten the time of assistance.
