Network experiment system based on closed-loop control and achieving method thereof

Abstract

Disclosed are a network experiment system based on closed-loop control and an achieving method of the network experiment system. The system comprises an entity experiment system, a control module, a measuring module, an on-site computer, a video monitoring system, an on-site server and a remote client, the entity experiment system is connected with the on-site computer through the control module and the measuring module, the measuring module is used for measuring parameter signals of the entity experiment system, the control module receives a control signal of the on-site computer and performs loop control over the entity experiment system, the on-site computer and the video monitoring system are respectively connected with the on-site server through a wired or wireless network, the control information and display information of the entity experiment system are transmitted to the on-site server, and on-site video information of a laboratory is transmitted to the on-site server. The system has the advantage of remote control, the experiment is converted into entity operation from virtual simulation, in the actual operation, the video telepresence technology is matched, an experimenter feels personal on the scene, resource sharing is achieved, and the utilization rate of the equipment is greatly improved.

Description

technical field [0001] The present invention relates to a network system and its method, in particular to a network experiment system closely related to automatic control, Internet of Things, video monitoring, data processing and teaching practice and its implementation method. Background technique [0002] With the popularization of higher education in our country, in recent years, special emphasis has been placed on strengthening engineering education in undergraduate training. Many colleges and universities have focused on the construction of practice bases and education and teaching experiment systems. However, due to limited funds, many schools often adopt theoretical Analysis replaces practical work, virtual simulation replaces physical experiment, and classroom demonstration replaces engineering practice. The results directly affect the improvement of teaching quality and the cultivation of students' engineering practice ability. Online distance education, especially ...

Problems solved by technology

[0007] The disadvantages of all the above technologies are: the direct control of the local experiment by sending signals from the remote computer belongs to open-loop control, and it is impossible to know whether the on-site construction experiment is completed at the remote end, which leads to the operation of the real equipment on site. The experimental circuit or experimental equipment may not meet expectations, resulting in experimental failure or even accidental disasters on site
