【摘要】 随着计算机技术和网络技术不断发展，远程教学作为一种新的教学模式方兴未艾。由于远程虚拟实验室能够解决实验室资金和资源相对紧张的状况，虚拟实验室在远程教学中得到了越来越广泛地应用。本文分析了虚拟实验室的现状，针对现有虚拟实验室的不足，提出了一种基于事件触发的远程虚拟实验室的系统架构，设计并实现了计算机硬件虚拟实验室平台(简称CHVL系统)，旨在建立一个开放的、协同的网上实验室。系统采用基于Java Bean的组件技术，能够提高开发效率，实现软件重用，使得系统易于维护和扩充。本文重点研究了虚拟元件库的设计与实现。同时，本文采用点对点和多点传送的方式实现CHVL系统中多个用户的信息共享，采用Java多线程技术实现用户对数据库及文件的访问，采用集中式并发控制算法解决了多用户同时进行数据请求的冲突协调，从而保证了共享数据的一致性和有效性。更多还原

【Abstract】 With the fast development of computer science and network technology, remoteeducation as a new education mode has already been in the ascendant. Becauseremote virtual laboratory can solve the problem of the relative shortage of funds andresources, it is more and more applied in the remote education.By analyzing the existing computer network course virtual lab system, the thesisproposes the architecture of an event-triggered remote virtual laboratory system.Computer hardware virtual laboratory platform (for short CHVL system), whichattempts to set up a exoteric and collaborative laboratory in network. Java Beantechnologies are used to implement the system, which support high efficiency ofdevelopment and reuse of software components, and also make the systemmaintaining and upgrading easily.The important research of the paper is the design and implementation of virtualcomponents library in handware virtual laboratory system.with adoptting theJavaBeans module technique to design the material objects of virtual components. Atthe same time the paper realized the information sharing of the users in the CHVLsystem according to the modes of dot is to the dot and the multipoint the transport.Weadopted Java multithread technique handles the request of serval consumers with theconcurrency control and guaranteed the consistency of the share data with theeffectiveness.更多还原
