摘　　要：为提高高校实验教学效果与学生实验成绩,提出基于虚拟仿真技术的高校实验在线教学系统。分析高校在线虚拟实验教学类型,结合分析结果与虚拟仿真技术,设计包括信息输入单元、实验教学虚拟交互单元以及信息输出单元的高校实验在线教学系统。用户通过信息输入单元输入指令,转换为虚拟计算机语言后,由实验教学虚拟交互单元接收指令,并调用相关虚拟实验场景与教学内容,将实验指导与仿真演示等操控指令提供给用户完成实验操作,获得的仿真实验数据经由该单元的数据清洗模块处理后,通过信息输出单元呈现给用户,完成高校实验在线虚拟仿真教学。结果表明,该系统可实现学生的实验结果提交、成绩查询、实验预约及教师的增减、查看与调整学生信息等功能,可明显提高学生的整体实验成绩,在高并发情况下具有良好的并发响应性能,满足高校实验在校教学的实际应用需求。A college experimental online teaching system based on virtual simulation technology is designed to improve the experimental teaching effect and raise the students′experiment results.The types of college online virtual experimental teachings are analyzed.In combination with the analysis results and virtual simulation technology,a college experimental online teaching system which includes information input unit,experimental teaching virtual interactive unit and information output unit is designed.The instructions are input and converted into the virtual computer language by the information input unit by the user.And then,the experimental teaching virtual interactive unit is used to receive the instructions,call the relevant virtual experimental scenes and teaching contents,and provide the control instructions of experimental guidance and simulation demonstration to the user to complete the experimental operation.The simulation experiment data obtained are processed by the data cleaning module of this unit and then presented to the user by the information output unit to fulfill the online virtual simulation teaching for college experiment.The results show that the system can realize the functions of students′experimental result submitting and score query,experiment reservation,increase or decrease of the number of teachers,and check and adjustment of student information,and improve the students′overall experiment results.In addition,the system has good concurrent response under the condition of high concurrency.Therefore,this system can meet the demand of practical application of college experimental teaching.
