In order to make the theoretical teaching and experimental teaching can be carried out simultaneously,and improve the scientific and technological interest of classroom teaching,a set of network-based automatic adjustment teaching system was designed and implemented for automatic control principle learning.The system can break through the limitation of time and space,so that teachers can control the equipment far away in the laboratory through the network at any time in the theoretical teaching,and transmit the data and images of the experimental equipment back to the classroom in real time through the network;in the case of network,students can also realize remote programming experiments by registering accounts and booking experiments,or operate the test bench locally to realize experiments related to control theory.
