Device for automatically judging experimental data by collecting and processing data

Abstract

The invention belongs to the technical field of experiment teaching, and provides a device for automatically judging experimental data by collecting and processing the data. The device comprises a multi-channel direct-current voltage measurement module, a multi-channel alternating-current effective value measurement module, a multi-channel signal frequency measurement module, a zero calibration and linear calibration module, an ESD protection module, a power supply module and a data transmission module. The device fills the blank of teaching instruments capable of automatically judging data. Due to an application of the device, justice and fairness of experiment assessment are ensured, the problems that part of students fabricate experiment data and plagiarize experiment results, and teachers need to spend a large amount of time and energy in correcting the experiment data which exist in experiment teaching for a long time are solved, the judgment accuracy and efficiency are improved,and the teaching effect is improved.

Description

technical field [0001] The invention belongs to the technical field of experimental teaching, and relates to a device for automatically judging experimental data by collecting and processing data. Background technique [0002] Electronic technology experiment teaching involves many working principles, many types of circuits, many experimental equipment, and many experimental data. At the same time, due to the discreteness of experimental device parameters and the differences in equipment used by students, the experimental data recorded by students The consistency is poor. In order to check and correct the experimental data recorded by students, teachers need to spend a lot of time and energy. [0003] Focusing on the above-mentioned problems in the teaching of electronic technology experiments, the designers of experimental equipment manufacturers and relevant teachers are trying to realize the automatic evaluation of the experimental data recorded by students through variou...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the long-standing problem that teachers need to spend a lot of time and energy correcting students' experimental data in the process of electronic technology experiment teaching, the present invention designs a method that can automatically collect, calibrate, transform, etc. the data from the experiment board. Comparing the final standard data with the experimental data recorded by the students and judging whether it is right or wrong, it is a device to automatically judge whether the experimental data recorded by the students is correct
