The digital inquiry laboratory mainly has the following functions and characteristics:
1.USB interface is used between data collector and computer, and between data collector and sensor. Four-channel sensor interface is used for parallel acquisition, plug and play, and durable.
2. The large LCD screen is convenient for observation and analysis. Computers can also be omitted when students are equipped with separate laboratories.
3. Portable design is convenient for organizing outdoor exploration experiment teaching activities.
4. The hardware structure design is beautiful and compact.
5. Two power supply modes, battery power supply, convenient for outdoor experiments.
6. With storage function, it is convenient to work offline.
7. Have a large number of sensors to meet the teaching needs of science, chemistry and biology, and can use the same collector.
8. Provide a humanized operating platform to facilitate inquiry and experimental research.
9. Automatically generate experimental reports, which is convenient for students to edit and submit experimental reports, including experimental data and images.
10. Experimental data and images can be saved separately, and experimental courseware can be automatically generated, which supports courseware playback.
1 1. Data points corresponding to image points can be flashed for easy observation.
12. Choose multiple storage forms to facilitate the processing and use of data and images. Multiple data tables and multiple experimental images generated by changing different experimental conditions during the same experiment can be saved at the same time, which is convenient for comparison.
13. Software is divided into special software and general software. The special software is simple, focused and intuitive, and the general software is powerful. Suitable for inquiry learning, support teachers and students to build experiments independently, encourage students to practice, and support multi-sensor combination experiments. According to the teaching needs, teachers can write new experimental scripts and expand special experiments.
14. Data and images can be displayed in multiple windows for comparison.
15. The experimental results can be displayed in various forms-the window can be switched to digital, pointer and waveform modes;
16. The same sensor can synchronously combine waveform-digital, waveform-instrument, waveform-waveform and other multi-mode displays, which greatly improves the observation effect of experimental phenomena. It can display a variety of accessed variables at the same time, or enlarge a variable to display it separately. For any accessed variable, the parallel or single display of data, tables and images can be realized.
17. Any kind of sensor can automatically generate variables in the combination diagram and calculation table, which is convenient for data acquisition, import and other processing.
18. Data recording: data is imported into the table by means of automatic recording, click recording and external calling, and the variables corresponding to the sensors are automatically generated in the table.
19. You can import the data into EXCEL spreadsheets and other software for other processing, or you can directly save the data for next call. You can create a new document directly in the calculation form without closing the software.
20. Formulas and variables: Formulas can be entered manually by operating the editing window, or can be entered into tables from the formula library, and independent record units will be automatically generated; Variables can be entered manually or generated automatically, and variables and constants can be entered; You can edit the formula yourself and save it in the template, which is convenient for next call.
2 1. Set a variety of data fitting methods for teaching.
22. Data calculation and graphic combination: support the conventional four operations, logarithm, exponent, trigonometric function, inverse trigonometric function and other operations, and draw data.
23. Coordinate drawing-A two-dimensional plane coordinate system can be automatically generated, X-axis and Y-axis variables can be customized according to experimental needs, experimental images such as time-varying and variables can be drawn in the coordinate system, and multiple groups of experimental images can be repeatedly drawn in the same coordinate system for comparison.
24. Line processing —— Basic functions: the image can be enlarged and reduced as a whole, with uniaxial stretching, compression and translation, and a single line can be selected for comprehensive processing. You can lock-unlock, hide-display any line, display experimental data in single point, line and line-single point combination, and display the coordinate values of data points in real time through footprints. The image can be displayed as a mirror image of the X axis or temporarily. The line type of drawing lines can be adjusted, and the image can be moved as a whole. You can also box and directly display the intercept of the box selection range on the X axis and Y axis.
25. The picture editor of the experimental interface can be copied as a whole, and the experimental interface can be directly saved as a picture.
26. You can print and save experimental data and images;
27. In the experiment, you can read the experimental help materials.
