Spectrometer experimental device

Abstract

The invention discloses a device for acquisition, transmission and real-time processing of spectrometer experimental data. The device comprises a collimator tube, a telescope, an objective table, an angular sensor, a circuit board embedded with a singlechip microcomputer, a Bluetooth emission module, a display device, a computer and a data processing program, wherein the computer is used for collecting the experimental data and processing the collected experimental data in real time and is provided with a Bluetooth receiving module, and the telescope is used for observation in a spectrometer experiment. The device is characterized in that the angular sensor is additionally arranged between a dial disc and the telescope and is connected with the singlechip microcomputer; data measured by the angular sensor are transmitted to the singlechip microcomputer, and the singlechip microcomputer transmits the data to the display device, which is connected with the singlechip microcomputer, in real time to be displayed; and after students completely measure the required data, a transmission button on the circuit board embedded with the singlechip microcomputer is pressed, data packets containing the data and student numbers as well as names are transmitted to a computer of a teacher through the Bluetooth emission module, and the computer is used for storing and postprocessing the data.

Description

technical field [0001] The invention relates to a university physics experiment device, mainly relates to a spectrometer experiment data collection, transmission and real-time processing system, and belongs to the field of university physics experiment instruments. Background technique [0002] Spectrometer experiment is one of the basic experiments in college physics experiment teaching, which mainly involves the observation of relevant optical phenomena and the measurement of angles. At present, most colleges and universities in China use traditional spectrometer experimental instruments. Decades of experimental teaching have proved that the main shortcomings of the traditional spectrometer experimental instrument: (1) Due to the current number of myopic students, it is very difficult to observe and adjust through the microscope; in the experiment, students need to constantly read the data. Repeated actions: observe through a microscope, read the value (angle value) on th...

Decades of experimental teaching have proved that the main shortcomings of the traditional spectrometer experimental instrument: (1) Due to the current number of myopic students, it is very difficult to observe and adjust through the microscope; in the experiment, students need to constantly read the data. Repeated actions: observe through a microscope, read the value (angle value) on the scale disc, and record the experimental data on the experimental report recording paper. Repeatedly, it is easy to cause visual fatigue and cause errors in angle counting, and if it occurs midway Collision, vibration and other disturbances will also cause counting failure

[0003] There are three problems in this kind of experimental process. First, it is not easy to understand the students' experimental mastery. As we all know, plagiarism among students is common. If students plagiarize other people's experimental data after the experiment, and use it Submitting the experiment report, the experiment teacher can't find out in time, because the student's data recording process is completely independent of the teacher, the result is that the teacher can't have a good understanding of the student's experimental mastery, which leads to the lack of confidence in teaching. There are deviations in quality assessment; second, students spend time and effort in the process of data recording, and the data are separated from each other, which is prone to errors; third, experimental teachers rely on experience to process student data, which inevitably occurs during the scoring process. deviation
