摘　　要：屏幕广播、文件分发、批量运行程序是计算机实验室中实验教学与设备管理的基本功能需求,文章围绕该需求设计并实现了基于UDP广播的实验室机房教学管理系统。系统利用了UDP广播在资源占用、报头开销、传输延迟等方面的诸多优点,同时设计了一套数据发送、接收的算法机制避免了其不能自动对数据进行分组、排序、组装等缺点,并通过极端模拟试验验证了该算法机制的有效性。此外,系统还设计了对传递的数据进行加密的机制以免遭恶意扰乱、攻击;提供了各种参数设置以使系统能适应不同机房性能参差不齐的电脑配置;系统实现采用了可以跨平台运行的Java SE以适应不同的操作系统。实际运用表明,该系统能显著提升实验教学的效果,能有效提升计算机设备的管理效率。Screen broadcasting,file distribution,running program in batch are the fundamental function requirements for improving the teaching effectiveness and management efficiency in computer lab.The paper designs and implements a computer lab teaching and management system based on UDP broadcast according to these requirements.The system uses the UDP broadcast's several advantage of low resources cost,small datagram head and low latency and designs a mechanism to avoid its shortage of inability of dividing,sorting and resembling of data.The paper also does an extreme situation simulation experiment which demonstrates the mechanism's effectiveness.The system designs encryption mechanism to avoid malicious disturbance and attack,provides parameter settings to better adapter different computer lab's configuration and performance and is implemented by Java SE that can run on different operation systems.The practical application of the system shows that it can significantly improve the effect of experimental teaching,the management efficiency of computer equipment and that it can substantially improve the teaching effect and equipment management efficiency.
