Description
Technical field
The present invention relates to a kind of computer long distance remote control experimental system and experimental technique thereof in the modern distance education.
Background technology
Long-distance education mainly utilizes broadcasting, TV, computer network or other means of communication to realize.Long-distance education should comprise long-range classroom and two aspects of experiment.Experiment in the long-distance education at present mainly adopts following several mode to carry out:
A kind of mode is utilized the virtual instrument of computer simulation technique and multimedia technology formation and the virtual experimental system that virtual unit is formed.Be that matrix experiment chamber software, Electronics Work-bench are EWB with MatLab for example, LabView is that virtual instrument, DAQDesigner carry out virtual experimental for pattern design.This is a kind of brand-new experimental technique.But state-of-the art, instrument, equipment and the experiment of instrument, equipment really with virtual mode constitutes also have very big difference aspect a lot, lack the sense of reality.
Another kind of mode adopts the mailing experimental box to experimentize in student family, finishes the method for returning again after the experiment.The tele-experimentation that adopts mailing way is arranged, but cost height, cycle are long abroad.
At present in the computer networking technology of using in the computer remote education, particularly can realize some softwares of long-range connection, for example Telnet is that telnet, Pc Anywhere are that remote computer, NetMeeting are that netmeeting software, RemoteExpert32 are long-range expert software, do not develop for tele-experimentation specially, equal defectiveness in the use, can not directly utilize these softwares to finish each link of tele-experimentation, still not have practical tele-experimentation Control Software at present.
Existing Computer Control Technology in normal experiment, by computing machine, can be controlled experimental provision; Utilize their various inputs, delivery outlet, the duty that can gather experimental facilities is utilized their serial communication interface in addition, makes the characteristics that data can two-way transmission, can realize the experiment based on Computer Control Technology.But depend the communication and the control function of computing machine alone, can't solve the serial operational issue of the programming of tele-experimentation medium-long range, remote debugging and remote monitoring.
