摘　　要：针对以往计算机实验室管理系统在同一时间只能对一台客户机进行远程控制,无法提高软件安装的工作效率,特别是考前测试时,无法实现集中控制,必须逐台电脑进行操作等问题,提出了一种计算机实验室并发式集中远程控制系统的解决方案。该系统利用UDP广播方式实现了对同一子网内的所有客户机进行集中控制,利用单播和时延技术,解决了某些系统瞬时承受能力有限的问题,利用窗口同步技术,实现了对客户机受控窗口位置和大小的同步,从而实现了鼠标精准定位的功能,同时系统还实现了各个客户端自动输入不同字符串的功能。应用实践表明,该系统只需通过一台管理机即可对多台客户机进行集中、统一、并发式的远程控制,尤其是在考前测试中,发挥了重要的作用,减轻了管理员的工作量,提高了工作效率。In the past, most of the computer laboratory management system can only control one client remotely at the same time, which can not improve the efficiency of software installation. Especially when pre-test, centralized control is not realized, and every machine must be operated gradually. The solution of the computer laboratory and the remote centralized control system is proposed. The system makes use of UDP broadcasting to achieve centralized control of all clients in the same subnet. Unicast and delay techniques have been used to solve the problem of limited transient capacity of some systems. The window synchronization technology is used to synchronize the position and size of the controlled window of the client, and realize the function of precise positioning of the mouse. The system also implements the functions of each client automatically entering different strings. Practical applications show that the system can centrally, uniformly and directly remote control multiple clients through a single management machine, especially playing a significant role in the pre-test, reducing the workload of the administrator and improving the work efficiency.
