随着远程教育和英特网的广泛应用，虚拟实验系统的研究逐渐被人们广泛关注，学生可以自由上网进入虚拟实验系统，操作设备，进行各种实验。远程虚拟实验不仅可以克服传统实验教学人力、物力、财力投入大的问题，更为远程实验教学的实施提供了条件和技术支持，也为远程教育的质量提供了有力的保证。因此，现有实验设备的虚拟实验化改造对远程教育有着很重要的意义。
本文在分析了带传动实验特点的基础上，结合远程教学的基本要求，提出了带传动远程控制实验系统的设计方案，针对设计要求，完成了系统的结构和硬件的设计。为了实现系统的设计目标，本文做了如下工作：
1. 带传动实验台硬件的改造设计。
2. 建立基于S7-300 PLC的带传动实验控制系统。
3. 为远程实验的教学软件提供数据接口和控制接口。
带传动远程控制实验系统不但具备了远程监控功能,而且保留现场的手动控制功能,不仅可以充分利用网络资源开展实验教学，而且可以通过网络进行远程实物实验，提高了教学实验效率和实验资源利用率。

Abstract
Along with the abroad application of remote education and Internet, virtual experiment system has become the focus in the field of research and application. Students can freely log on the virtual lab system, operating on instrument, carrying on every type of experiment. Not only can remote and virtual experiments overcome the problem of devotion in manpower, material resources and financial resources in traditional experiment, but also providing environment and tech supports for remote experimentally teaching, also affording powerful pledge for the quality of remote education. So, it is very mean for remote education to reconstruct the in existence experiment instrument.
Based on analyzing the belt-driven experiment and its characteristic, combine with the basic requests of remote education. The design of remote control belt-driven experiment system is brought forward. Based on the requests, the structure and hardware are designed. To fulfill the system, the following researches are done:
1. The hardware design of the belt-driven experiment instrument.
2. Build belt-driven experiment control system based on S7-300 PLC.
3. Offer date interface and control interface for remote experiment education software.
The remote control belt-driven experiment system has the remote control function and remains the local manual function，can not only take full of network resources to develop experimental teaching, but also develop remote real time practicality experiment on network, improving the teaching experiment efficiency and making full use of the experiment resources.
