Description
Technical field
The present invention relates to the exploitation of a kind of Analog Electronics Technique exercise system and exercise question thereof and user's exercising method, especially onePlant the changed randomly Analog Electronics Technique exercise system of circuit parameter and exercise question exploitation and user's exercising method, belong to electronicsTechnical field.
Background technology
Analog Electronics Technique is the important technical foundation course of electronic information, communication and Electric Specialty, be carry out follow-upThe basis of the specialized courses study such as High-Frenquency Electronic Technology, single-chip microcomputer and interfacing. But as first electronics of student's contactTechnical course, the feature such as Analog Electronics Technique has that knowledge involves a wide range of knowledge, theoretical property is strong, conceptual abstraction, practicality are strong, therebyStudent generally thinks that learning simulation electronic technology exists larger difficulty.
In order to learn Analog Electronics Technique well, student need to do a lot of practice, but present Analog Electronics Technique exercise system,Having following several deficiency: (1), exercise question are static exercise question, is also that content and the answer of per pass exercise question all fixed, and this gives topicIt is unfavorable that storehouse builder and user bring, and the former unfavorable shown: when to a circuit exploitation exercise question, in order to allow user learnPractise the various typicalnesses of this circuit, need to develop several circuit topologies identical, but the circuit parameter exercise question different with answer,Both increase workload, again artificially same learning content, be helplessly divided into association in essence, but in form independently manyIndividual exercise question; Show as the latter is unfavorable: when study is when a circuit, in order to grasp the various typicalnesses of this circuit, need to be fromIn exam pool, find one by one, recall relevant exercise question and practise, this has just reduced learning efficiency; (2), the circuit diagram of exercise question is with image paneFormula storage, exam pool memory space expense is large; (3), user is while practising, the circuit diagram that exercise question shows is clear not, affect vision and imitatesReally. These deficiencies, for item banking person, the item banking workload having increased, for user, has reduced study effectRate, for exercise system, exam pool memory space expense is large.
The deficiency of above-mentioned Analog Electronics Technique exercise system, with circuit diagram drafting, the circuit diagram storage of current exercise systemClosely related with circuit diagram reproduction mode. The exercise question of Analog Electronics Technique, generally comprises two parts: the text of circuit diagram and exercise questionPart. Circuit diagram is used element graphical symbol and is connected line drawing art circuit topology, uses character display circuit parameter, and circuit parameter is mainThere are input voltage value, device parameter values and supply voltage value; The textual portions of exercise question is used for introducing exercise question and rhetoric question. Current,When exercise question exploitation, must, by means of third party's circuit tracing instrument, as the software such as EWB, Proteus, draw the circuit diagram of exercise question,On circuit diagram, edit circuit parameter, then circuit diagram is extracted, converts to picture format, finally with picture format memory circuitFigure; In when application exercise, exercise system is by reading the circuit image data of exam pool, then uses Image control display circuit figure. AsThis circuit diagram is drawn, circuit diagram storage and circuit diagram reproduction mode can cause: (1), can not show circuit parameter with circuit diagramVariation, because of the circuit diagram of drawing from third party's circuit tracing instrument, to generative circuit image, be an irreversible process, oneDawn has been transformed into picture format, and at practice stage, exercise system just can not modification circuits figure; (2), exam pool is with picture formatThe circuit diagram of storage exercise question, memory space expense is large; (3), when exercise, circuit diagram reappears to user by image format, due toDimensional variations reason, image occur compression or stretch, easily cause circuit diagram fuzzy or distortion.
Chinese patent application " method (the publication number CN of calculation question changeable parameters in a kind of electric power examination system103761101A) " method of calculation question changeable parameters in a kind of electric power examination system is disclosed. Utilize this publish method, canRealize calculation question parameter change at random in limited range. But its weak point is: when (1), exercise, in the textual portions of exercise questionCircuit parameter to change at random describes, and the circuit diagram of exercise question only reflects interelement annexation, does not relate to circuit ginsengNumber, is not inconsistent with ordinary practice; (2), parameter version is single, is only the number of getting at random limited range, and parameter changes definitionMore complicated; (3) model answer changing with parameter, is not provided, thereby can not be with doing the exercises; (4), circuit diagram is to schemeThe storage of picture form, exam pool memory space expense is large; (5), when reproducing circuit figure, circuit diagram is clear not.
