The Research And Design Of Virtual Laboratory Of Process Control Based On LabVIEW

Experiment is a necessary part of teaching, which can cultivate the students'abilities of manipulating practically and the abilities of finding and resolving problems. However, not all of the colleges can provide the necessary experimental environment, many compulsory experiments can't be carried out due to various reasons. As an essential and helpful complementarity to traditional experiment, virtual experiment has more preferable economic benefit, better pertinence, larger opening character and absolutely security. All the characters ensure that virtual experiment has a wide foreground in educational and scientific research field ,and becomes to be a new developmental direction of experiment teaching as well as to be a pop study in modern world. Moreover, process control is an important subject of automation, but its experimental equipment is very destitute. Therefore, setting up a web-based virtual laboratory of process control is of great necessary.This thesis is one of the Tianjin informational projects. Based on the analyzing of the requirements to virtual laboratory system according to the actual situations of universities, the thesis discusses the constructing process of process control virtual laboratory system from several aspects. Each aspect is as follows: the building of virtual laboratory system, the design of virtual laboratory management module, the contriving of typical process control experiment and the network function of virtual laboratory system.Taking LabVIEW as a developing platform, the thesis constructs a real-time, interactive and extending virtual laboratory system. This system can make full use of network resource, reduce hardware investing, which makes it a low-cost, high profit information-based foundation with prodigious practical signification.
