Description

The spectrometer experiment device

Technical field

The utility model relates to a kind of Experiment of College Physics device, relates generally to a kind of collection, transmission and real time processing system of spectrometer experiment data, belongs to the Experiment of College Physics instrument field.

Background technology

Spectrometer experiment is one of basic experiment of college physical experiment teaching, is mainly concerned with the adjusting of relevant optical phenomena and the measurement of angle.What domestic majority colleges and universities adopted at present all is traditional spectrometer experiment appearance.The experimental teaching of decades proves, the major defect that traditional spectrometer experiment appearance exists: because present near-sighted student's ratio is more, it is very painstaking to regulate through microscopic examination (1); In the experiment; The student is in the process of reading of data; Need the action that constantly repeats: through microscopic examination, read numerical value (angle value) on the dial disc, on the laboratory report recording chart, write down experimental data; So repeatedly, be easy to visual fatigue occur and cause angle numeration mistake, and if occur interference such as collision, vibration midway and also can cause to count and fail.These factors are longer experimental period of student's cost and the main cause that artificial measuring error occurs often.(2) existing process all is that the student observes in microscope, reads the reading on the spectrometer experiment appearance dial disc then, again reading is carried out write by hand, and the laboratory report of being submitted to all is that the experimental data with write by hand is the basis.

There are three problems in such experimentation; First: the experiment grasp degree for the student is difficult for understanding, and well-known, the plagiarism phenomenon between the student is ubiquitous; If the student has plagiarized other people experimental data after experiment; And submit 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 utility model proposes to above-mentioned problem, and a kind of spectrometer experiment device is provided, and it can realize the content of traditional spectrometer experiment, 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

Embodiment according to the utility model; A kind of spectrometer experiment device is provided; Comprise: parallel light tube, telescope, objective table, angular transducer, the circuit board that is embedded with single-chip microcomputer, Bluetooth transmission module, display, be used for that experimental data is collected and the computing machine of the configuration bluetooth receiver module handled in real time; Spectrometer experiment uses telescope to observe, and it is characterized in that: this spectrometer experiment appearance has installed angular transducer additional between dial disc and telescope, this angular transducer is connected with single-chip microcomputer; The angular transducer data measured can be transferred to single-chip microcomputer; On the display that single-chip microcomputer sends data in real time and be presented to again with single-chip microcomputer is connected, after the student all measures desired data, by " transmission " button on the circuit board that is embedded with single-chip microcomputer; The packet that comprises above-mentioned data and student numbering and name sends to through the Bluetooth transmission module on teacher's the computing machine, by computing machine data is stored and subsequent treatment again.

Spectrometer experiment uses telescope to observe, and prior art is very ripe, no longer gives unnecessary details at this.The utility model is characterised in that: be furnished with angular transducer on this spectrometer experiment instrument; This angular transducer is connected with single-chip microcomputer; The angular transducer data measured can be transferred to single-chip microcomputer, and single-chip microcomputer sends data in real time and be presented on the coupled LCD that connects again.After the student all measures desired data; By " transmission " button on the circuit board that is embedded with single-chip microcomputer; The packet that comprises above-mentioned data and student numbering and name sends to through the Bluetooth transmission module on teacher's the computing machine, by computing machine data is carried out subsequent treatment again.

Pass through said apparatus; Just solved foregoing problems, in the experiment, the student needn't be on telescope, dial disc, laboratory report recording chart back and forth repeatedly; Only need the bright line in the intent observation telescope visual field; In the time of the needs record data, press " record " button on the circuit board that is embedded with single-chip microcomputer, data are transferred to display through single-chip microcomputer automatically; Whenever after once testing, the experimental data of on display, seeing this time that the student can both be real-time also is the angle that telescope turned over; If it is dissatisfied for experimental result; Can experimentize again directly with data deletion, 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.
