Potential difference meter experimental apparatus

Abstract

The invention discloses an acquiring, transmitting and real-time processing apparatus of experimental data of a potential difference meter. The apparatus comprises a potential difference meter board, a galvanometer, a circuit board embedded with a single-chip, a Bluetooth transmission module, a display and a computer used for collection and real-time processing of the experimental data and configured with a Bluetooth reception module. 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 containingthe 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 boardwhich is embedded with the single-chip; and then the computer performs subsequent processing on the data.

Description

technical field [0001] The invention relates to a university physics experiment device, mainly relates to a potentiometer experiment data collection, transmission and real-time processing system, and belongs to the field of university physics experiment instruments. Background technique [0002] Potentiometer experiment is one of the basic experiments in college physics experiment teaching, which mainly involves direct and accurate measurement of potential difference in electrical measurement, measurement of battery electromotive force and other experimental content. At present, most colleges and universities in China use sliding wire potentiometers. During the experiment, students read the length of the resistance wire by moving the position of the sliding contact, and record the data on the experimental report paper to calculate the potential difference or Electromotive force of the battery. [0003] There are three problems in this kind of experimental process. First, it...

Problems solved by technology

[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
