The utility aims at solving the problems as below: the existing circuit evaluation adopts the dedicated circuit board and artificial scoring method which requires large investment and heavy workload of the examiner; the subjective difference may appear during scoring thereby influencing the justice of the scoring results. The key points of the technical proposal are as blew: the utility model is characterized in that the utility model comprises a shell, and a programmable controller, a subject selecting toggle, a start button, a reposition button, a human computer interface and evaluated circuit connecting interfaces which are arranged on the shell, wherein, the human computer interface is connected with a communicating interface of the programmable controller, the subject selecting toggle, the start button and the reposition button are connected with an input interface of the programmable controller, the evaluated circuit connecting interfaces is connected with the input interface and the output interface of the programmable controller. The utility model is specially suitable for professional skill education and training.
Description
Technical field
The utility model belongs to the instruments used for education of school, specifically is a kind of automatic scoring device that the Experiment of Electrical Circuits effect is examined of being used for.Be specially adapted to vocational skills teaching or training.
Background technology
Along with the high speed development of Chinese national economy, the electromechanical industries development is also rapid unusually, and China has become the machining center in the world in economic globalization at present, under this situation, demand for dynamo-electric personnel increases substantially, so the teaching or the training of vocational skills and so on are more and more heavier.According to measuring and calculating, in recent years, annual plan identifies that the number of vocational skills is about about 1,000 ten thousand people, and during electrician's technical ability is identified at present the Experiment of Electrical Circuits effect is examined is to adopt artificial methods of marking, its general flow is: the examinee is by the examination paper requirement, finishes the examination task and form circuit examination workpiece on the special circuit plate, and the examiner makes energizing test to circuit examination workpiece, according to test findings, manually mark; Such methods of marking brings following drawback: be the special circuit plate because of what use at first, a kind of special circuit plate only is applicable to a circuit diagram, in order to adapt to a plurality of different teaching and examination circuit diagram, required special circuit plate kind is corresponding more, and this certainly will cause the bigger fund of input; If in order to cut down expenses, corresponding special circuit plate can only be used less, this just has influence on the confidence level of examination; Secondly, owing to take artificial scoring, examiner's labor capacity is very big, the subjectivity difference when also scoring occurring easily, and this has just departed from justice and principle of justice.
Summary of the invention
The special circuit plate is adopted in available circuit examination and the artificial existing fund input of methods of marking is big, examiner's workload is big in order to overcome, occur subjectivity difference easily in the scoring process, influence the defectives such as fairness of appraisal result, the purpose of this utility model provides a kind of improvement circuit examination automatic scoring device, can overcome the defective of prior art.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of circuit examination automatic scoring device, it is characterized in that: comprise housing and be installed in the programmable controller on the housing, select a topic DIP device, start button, reset button, man-machine interface, examination circuit connectivity port, wherein man-machine interface is connected with the communication interface of programmable controller, selected topic DIP device, start button are connected with the input interface of programmable controller with reset button, and examination circuit connectivity port is connected with output interface with the input interface of programmable controller.
The programmable controller of such scheme also claims PLC, is a kind of ready-made electronic installation that is used to finish the digital operation operation.
The beneficial effects of the utility model: owing to adopt programmable controller to finish automatic scoring device digital operation operation, after the automatic scoring program is written to programmable controller, just the circuit board that a student finishes connection can be refuted and receive on the examination circuit connectivity port, operation selected topic DIP device start button and reset button, the student is finished the examination task and the situation that forms the universalization workpiece of circuit examination is carried out automatic scoring, and the automatic scoring result is shown on man-machine interface.So an examiner amasss little automatic scoring device with a stage body, just can be convenient, fast, exactly multidigit examinee and multiple teaching circuit are marked, alleviated examiner's labor capacity greatly, the accuracy height of scoring, avoid occurring subjectivity difference, improve justice and the fairness passed judgment on.

Write FX
2NThe automatic scoring program of-48MR type programmable controller adopts the trapezoid figure language programming of PLC special use, can carry out according to the following rules during programming:
The examinee is by N (N is a natural number) the examination requirement that examination paper propose, and finishes the examination task and form the universalization workpiece (hereinafter to be referred as circuit board) of circuit examination on the teaching circuit board.
When the examiner marked, behind the interface and the connectivity port connection of examination circuit with circuit board, the DIP device 3 of will selecting a topic was transferred to N, clicks start button 4, and then the automatic scoring program is moved automatically by following rule:
1. require scoring according to first examination: send the 1st group of signal specific to circuit board by output interface 10, circuit board is opposed should move → operation result of circuit board with the automatic decision circuitry plate of the input interface 9 → PLC operation result that the form of signal inserts PLC whether correct → if the circuit board operation result is correct, the 1st score of this circuit board then; If the circuit board operation result is incorrect, then the 1st of this circuit board not score → appraisal result deposit in automatically in the PLC storer.
2. require scoring according to the 2nd examination: (with 1. roughly the same).
……
