Problems solved by technology

[0005] With the prevalence of network virtual experiment teaching system, there are two problems: one is that due to the large number of students participating in the virtual experiment, and the time is not fixed, the correction of the remote virtual experiment will bring a heavy burden to teachers; There are many courses, and it would be redundant work to implement a correction tool for each course, so it is necessary to design a general method for correcting virtual experiments for one class of courses

Embodiment Construction

[0030] The embodiment of the present invention proposes a remote automatic correction method for virtual experiments of circuits. First, the input standard answer experiment script is analyzed to obtain the instrument equipment object set and the instrument port object set; then, from the instrument equipment object Centrally extract the set of scoring points of the instrument and equipment, extract the set of scoring points of the circuit connection from the instrument port object set; The script is parsed into an instrument device object and an instrument port object, and the instrument device object and the instrument port object are converted into fact data; the next step is to traverse each instrument device scoring point and circuit connection scoring point to determine whether the fact data is consistent with The score points of the instrument equipment and the score points of the circuit connection match, if so, the scores corresponding to the score points of the matche...

Abstract

The invention provides a remote automatic correcting method for circuit virtual experiments, which comprises the following steps of: resolving input standard answer experiment scripts to obtain a set of apparatus score points and a set of circuit connection score points; selecting the required score points from the score point sets, and setting a score corresponding to each score point, wherein after the setting is finished, the score point is a score rule and a plurality of score rules form a score rule base; resolving virtual experiment scripts to be corrected into apparatus objects and apparatus port objects, and converting the apparatus objects and the apparatus port objects into factual data; judging whether the factual data are matched with the score rules in the score rule base, and recording the matching result of each score rule during matching; and accumulating the scores of the successfully matched score rules to obtain a total score of experiment correction, and outputting the matching results and the scores serving as corrected score sheets.

Description

technical field [0001] The invention relates to the technical field of computer Internet, in particular to a remote automatic correction method and system for circuit virtual experiments. Background technique [0002] In recent years, with the rapid development of the Internet, the forms of modern distance education based on the Internet have also become rich and diverse. Among them, the application of the network virtual experiment teaching system constructed by virtual reality technology and Web technology has reached an unprecedented scale. [0003] Virtual experiment refers to the use of multimedia, simulation and virtual reality technologies to create relevant software and hardware operating environments on the computer that can assist, partially replace or even completely replace the various operating links of traditional experiments. Experimenters can complete various tasks in the virtual reality environment. This kind of experimental project, the experimental effect...
