virtual laboratory for Corporations: The Source of Policy

Journal of Southeast University(English Edition) 2000年第1期16卷 95-100页

作者：于跃海何建敏东南大学经济管理学院南京210096

Many corporations are complaining that they cannot make decisions correctly. This article describes virtual laboratory (VL), an organization which can help managers make decision. The virtual laboratory based on Intranet uses many methods to draw policies for the corporation by analyzing business processes. It is a tool for learning organization too.

This The Computer Component Expedient virtual laboratory System has established a virtual platform for the real-time test of high schools’ computer component principle network, and has provide calculator, controller, dynamic and static memory chips, decoding circuit chips, and other programmable chips and commonly used electrical gate logic chips to do virtual test for computer component principles. Based on the design of chip circuit and instruction system, a simple computer system’s virtual realization can be carried out in virtual laboratory. With the computer component principle test, this paper has made research related to the analysis and design of the test rules of virtual teaching laboratory, and used production system and forward reasoning to design the rule auditing module. This has provided theory evidence for the realization of intellectual virtual teaching laboratory system.

With the popularization of STEM（Science, Technology, Engineering, Mathematics） education in the world, more and more universities are paying attention to combination of science and engineering, especially in the field of robotics and automation because of its multidisciplinary characteristic. With respect to the teaching laboratory of real robot, it is insufficient to meet the requirements of students for the limited resources in the laboratories and their opening times. What’s more, there are some unknown potential risks in real robot labs which are not conducive to students’ normal use. However, some flexible solutions have been developed to permit an effective teaching in the labs of robotics and automation systems. One of these solutions is the virtual laboratory based Web, which is an effective tool to provide the requirements help for hands-on experiment. The proposed platform of the virtual laboratory in this paper has been used to innovate engineering education. The proposed virtual lab covers required knowledge of the robot kinematics and dynamics utilizing MATLAB as programming language. In addition, all projects of the virtual laboratory platform can be further developed besides some designed experimental projects, which means the users can do research based on the virtual laboratory same as the real laboratory. Furthermore, multi-functions of virtual laboratory platform from different perspectives are illustrated in this paper. The virtual laboratory platform has been applied in the department of automation in Beihang university for practical teaching of undergraduates. The results show two advantages of the virtual lab. One is that students learn about the robot knowledge effectively in the virtual lab, the other one is they can use their new ideas to innovate the project development. The proposed virtual laboratory provides an efficient learning platform for combination of science and engineering to innovate education.

第三十九届中国控制会议

作者： Xingle Feng Wenshan Hu Hong Zhou Guo-Ping Liu Wuhan University

To solve the problems from the huge power plant emulator machine and the virtual DCS system, this paper develops a remote virtual thermal process control laboratory for power plants based on the Networked Control System laboratory（NCSLab）. Without the huge simulation machine, heavy desktop software, and specific experimental environment, NCSLab combines the traditional thermal process control experiments with remote control and online virtual simulating technology. Moreover, a new set of visual widgets is applied for imitating the real master controlling interface in the simulator machine and virtual DCS. The proposed thermal process control laboratory provides an online solution for basic experimental systems such as the boiler drum water level control system and the main steam temperature control system, which strengthens the flexibilities of thermal power training.
