Description
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 equal thickness interference experiment data, belongs to the Experiment of College Physics instrument field.
Background technology
Equal thickness interference experiment is one of basic experiment of college physical experiment teaching.What domestic majority colleges and universities adopted at present all is traditional Equal-Thickness Interferometer.The experimental teaching of decades proves that there are several major defects in traditional Equal-Thickness Interferometer: 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 fringe number; Need the action that constantly repeats: through microscopic examination, read numerical value on the scale, on the laboratory report recording chart, write down experimental data; So repeatedly, be easy to visual fatigue occur and cause striped 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) because the reading microscope field range is less, the observing effect of experiment is not good enough.Have the researchist that beam coupling device (CCD) is applied in this experiment now, the transmission of interference fringe on a large scale that the beam coupling device will collect is connected to computer, makes things convenient for the observer in computer, to observe and data analysis.But do every Equal-Thickness Interferometer like this and all will be equipped with a computer, need a large amount of fund inputs, have waste to a certain degree.
At present; The equal thickness interference experiment process of domestic colleges and universities all is that the student observes in microscope, writes down the fringe number in the visual field, reads the reading of scale on the Equal-Thickness Interferometer then; Again reading is carried out write by hand, 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; A kind of collection, transmission and real time processing system of equal thickness interference experiment data are provided; Only need traditional Equal-Thickness Interferometer is reequiped; Recondition expense is cheap, and it can realize the project of traditional equal thickness interference 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 collection, transmission and real time processing system of equal thickness interference experiment data are provided, have comprised: equal thickness interference generation device, microscope, digimatic calipers, the computing machine and the data processor that are embedded with single chip circuit plate, Bluetooth wireless transmission module, LCD, are used for the experimental data collection and handle in real time.
Equal thickness interference experiment uses microscope 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 digimatic calipers on this Equal-Thickness Interferometer; This digimatic calipers is connected with single-chip microcomputer, and single-chip microcomputer can be real-time transmitted to electronic digit scale data presented content and be presented on the LCD that is connected on the single-chip microcomputer.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, again data is carried out subsequent treatment after being received by computing machine.
Through said apparatus, just solved aforesaid problem.In the experiment; The student needn't only need the striped in the intent viewing microscope visual field, in the time of the needs record data on microscope, scale, laboratory report recording chart back and forth repeatedly; Press " record " button on the digimatic calipers, 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 dimensional data of striped; 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; The 4th, this device is the transformation to traditional equal thickness interferometer, and only needing increases the little electrons components and parts, can realize that a teacher organizes the data storage and the processing of experimental provision, cost with computing machine to a plurality of students.
