The apparatus is characterized in that the potential difference meter experimental apparatus is configured with an electronic digital display caliper which is connected with the single-chip; when a student needs to record data, data content measured by the electronic digital display caliper can be transmitted in real time and displayed on a display which is connected with the single-chip by pressing down a recording button on the circuit board which is embedded with the single-chip; after the student measures all the needed data, a data packet containing the data as well as the serial number and the name of the student can be transmitted to the computer through the Bluetooth transmission module by pressing down the sending button on the circuit board which is embedded with the single-chip; and then the computer performs subsequent processing on the data.
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 potential meter experiment data, belong to the Experiment of College Physics instrument field.
Background technology
Potential meter experiment is one of basic experiment of college physical experiment teaching, relates generally to and directly accurately measure potential difference (PD) in the electrical measurement, measures experiment contents such as cell emf.What at present domestic most of colleges and universities adopted is slip formula potential difference meter, and the student by the position of mobile slider, reads the length of resistance wire in experimentation, at laboratory report paper identifying recording layer, thus the electromotive force of the potential difference (PD) of calculating or battery.
There are three problems in such experimentation, 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 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 present invention proposes at above-mentioned problem, a kind of collection, transmission and real time processing system of potential meter experiment data are provided, it can realize the experiment content of traditional electrical tentiometer, and conveniently reads experimental data accurately, transmits experimental data and handle 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 potential meter experiment data are provided, have comprised: potential difference 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.
Existing slip formula potential difference meter technology is very ripe, no longer gives unnecessary details at this.The invention is characterized in: be furnished with digimatic calipers on this potential meter experiment instrument, this digimatic calipers is connected with single-chip microcomputer, when the student needs record data, press " record " button, single-chip microcomputer can be real-time transmitted to the data content that digimatic calipers is measured and be presented on the coupled LCD.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.
Pass through said apparatus, just solve aforesaid problem, whenever after once testing, the student can both be real-time the experimental data of on display, seeing this time, also be the angle that telescope turned over, 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.

Specific embodiment
Fig. 1 shows the circuit diagram of potential meter experiment among the present invention, and this part is consistent with potential difference meter of the prior art, has installed digimatic calipers 2 additional at slider N and 1 on scale among the present invention.
The invention is characterized in its collection that also comprises data, transmission and receiver module.The student moves slider N, when electric current is 0 among the galvanometer G, by " record " button on the circuit board that is embedded with single-chip microcomputer, single-chip microcomputer reads the reading of digimatic calipers automatically, obtain the length of resistance wire, and with on this data transmission to one coupled display, and, be embedded with on the circuit board of single-chip microcomputer and also be provided with " transmission " button and Bluetooth transmission module, described by pressing " transmission " button, described Bluetooth transmission module can be sent to the packet that includes student information and above-mentioned data the bluetooth receiver module on teacher's computing machine, receives back storage and processing on this computing machine.
Display: the data that the singlechip chip collection is come are all shown experiment content and data by one 8 inch TFT LCD.The experimental data that the student observes by liquid crystal display has associative perception, can be by the data of contrast different measuring group, the operating mistake that may exist in the judgment experiment.For misdata, can directly delete by " deletion " key on the circuit board that is embedded with single-chip microcomputer.The user can also select LCD different, suitable dimension according to what difference of data in the experiment.
Data transmit: experimental data is stored in the single-chip microcomputer temporarily, and the circuit board that is embedded with single-chip microcomputer is provided with " transmission " button, clicks this button, and then data send by the blue teeth wireless signal through bluetooth module.
Data Receiving: be inserted with Bluetooth adapter on the computing machine as the bluetooth receiver module, can receive Bluetooth signal.
Data in real time is handled: the program that writes is arranged on the computing machine, read the data that Bluetooth adapter receives, the storage experimental data is to being in the file of filename, as data backup with student's student number and name.Simultaneously, computer program also can be handled experimental data, is presented on the computer screen experiment quality of doing with teacher's real-time judge student of convenient teaching during fructufy after the processing, and provide objective basis for correcting laboratory report, make things convenient for the teacher to screen the accuracy of student data.
If want to change the part experiment content, only need in single-chip microcomputer write-in program again, adjust the liquid crystal display displaying contents, rewrite computer processing, can save big measuring appratus and upgrade and improvement expenses.
