Description
Technical field
The present invention relates to a kind of Experiment of College Physics device, relate generally to a kind of collection, transmission and real time processing system of characteristic of solar cell determination experiment data, belong to the Experiment of College Physics instrument field.
Background technology
The world today, non-renewable energy resources such as electric power, coal, oil signal for help repeatedly, when energy problem becomes the bottleneck of restriction international community economic development day by day; More and more countries comes into effect and turns to regenerative resource to sight; Wherein, exploitation sun power is one of research focus.
The application of sun power, one of them big direction is to utilize solar cell, directly converts sunshine to electric energy.Its ultimate principle is: solar irradiation forms new hole-electron pair on the semiconductor p-n junction, under the p-n junction effect of electric field, the hole flows to the n district by the p district, and electronics flows to the p district by the n district, just forms electric current behind the connection circuit.
Existing nowadays college physics teaching also grows with each passing hour in the colleges and universities, and the characteristic of solar cell determination experiment has become one of a lot of colleges and universities College Physics basic experiment.In the characteristic of solar cell determination experiment; Under different condition; Like full dark condition, certain light intensity condition and different light intensity condition, measure the volt-ampere characteristic of solar cell respectively, the data of its collection are many directly to be shown through DC digital voltage meter and DC digital amp gauge; Student's write by hand is recorded in above the laboratory report paper then.
Yet there are three problems in such experimentation, and first: the experiment grasp degree for the student is difficult for understanding; As everyone knows; Plagiarism phenomenon between the student is ubiquitous, if the student has plagiarized other people experimental data after experiment, and submits laboratory report to this; Experiment teacher can not in time find this; Because student's data recording process is independent of teacher fully, to be exactly teacher grasp degree for student's experiment to the consequence that causes like this can not have one and well understand, and then cause deviation occurring for the assessment of quality of instruction; The second, time-consuming in data recording process, the effort of student, data are discrete to each other, are easy to generate mistake; The 3rd, to the processing of student data how by rule of thumb the experiment teacher deviation inevitably occurs in scoring process.
The present invention proposes to above-mentioned problem; A kind of collection, transmission and real time processing system of characteristic of solar cell determination experiment data are provided; It can measure cut-off voltage, and convenience reads experimental data accurately, transmits data, handles experimental data in real time.In teaching, can change experiment content at any time according to the experiment needs, simple, easy row.
Summary of the invention
According to one embodiment of the invention; A kind of collection, transmission and real time processing system of characteristic of solar cell determination experiment data are provided, have comprised: light source, solar cell box, the tester that is integrated with DC digital amp gauge and DC digital voltage meter, the circuit board that is embedded with single-chip microcomputer, Bluetooth wireless transmission module, LCD, the computing machine and the data processor that are used for the experimental data collection and handle in real time.
Present characteristic of solar cell determination experiment device comprises light source, solar cell box, is integrated with the tester of DC digital amp gauge and DC digital voltage meter, and prior art is very ripe, no longer gives unnecessary details at this.The invention is characterized in: in this characteristic of solar cell determination experiment device; The same single-chip microcomputer of tester is connected; When the student measures output voltage and the output current of solar cell; Press " record " button on the circuit board that is embedded with single-chip microcomputer, single-chip microcomputer can send the voltage and current data in real time and be presented on the coupled LCD that connects.After the student all measured desired data, by " transmission " button, the packet that comprises above-mentioned data and student numbering and name sent to through the Bluetooth transmission module on teacher's the computing machine, by computing machine data is carried out subsequent treatment again.
Through said apparatus, just solve aforesaid problem, after whenever once testing; The student can both be real-time the experimental data of on display, seeing this time; Also be the data of the output voltage and the output current of solar cell, if dissatisfied for experimental result, could be directly with data deletion; Again experimentize, what it was seen at last is whole experimental data of an integral body; Moreover after the each experiment of student finished, the experimental data that all needs to include personal information sent on teacher's the computing machine, can guarantee that teacher sees the experimental data that each student is original, has effectively prevented to plagiarize between the student generation of phenomenon; The 3rd, adopt this system, computer program with Data Processing in Experiment and storage after, can call at any time, as the objective basis of teacher when the given laboratory report mark, thereby carry out conveniently, just experimental evaluation.
