Abstract


Remote control laboratory system, is based on the rapid development of Internet network, using computer automatic control technology, network communication technology, simulation technology, multimedia technology, network technology, database technology and Web online distance consisting of advanced control systems in higher education has broad application prospects and development space. College of Automation, Chongqing University Experimental Center of Automatic Control Theory to reform the current laboratory to simulate the experimental box as the main subjects of the status quo, introduced from abroad advanced laboratory equipment, such as the inverted pendulum, experimental tank, twin-rotor, magnetic levitation. The face of the dramatic increase in the number of college students, experimental resources can not meet the current needs of the situation, automatic remote control laboratory laboratory construction projects proposed use of limited resources to meet the needs of experimental teaching. The issue stems from Chongqing University teaching reform pilot projects. Currently, the angle options from a network computer remote monitoring solutions mainly in the following two ways: based on C / S mode of remote monitoring programs and Web-based technologies (ie B / S mode) for remote monitoring solution. By comparison, based on B / S mode for remote monitoring and application development environment to achieve a separation of the environment, so that the development environment independent of the user's application environment. This article was based on B / S mode implementation of remote monitoring. Determined on the basis of the program, this key technology for remote experimental research and exposition, including network communication technology, database access technology, control terminal board with data communications, video surveillance technology and network security technology. Remote laboratory architecture consists of client layer, the server layer, control layer, and four controlled object. Client layer network users to access the system via the Internet, using the system of the device. Server layer is mainly centralized data management and the management of client access mechanism. Control layer to control computers, mainly used to control a variety of field level control devices. Field level is mainly related to a variety of laboratory equipment, such as the inverted pendulum, twin-rotor, three-tank model. Remote laboratory building into a remote virtual labs and remote labs two-step. This paper presents a remote virtual labs and remote lab design has now achieved a remote virtual experiments. Principles of Automatic Control Laboratory combines the actual situation, choose the double rotor and magnetic levitation as the controlled object, first build remote virtual experiments to build mathematical models for remote simulation. This paper introduces the realization of remote virtual experiment system, complete the client program is designed to build client applications, gives double rotor and magnetic levitation experiment interface and simulation curve. Finally this paper, a summary of the remote experiment system, pointed out that the development of remote laboratories in the network security technology, video surveillance technology and control object control algorithms work and other aspects to be resolved.
