Experiment teaching auxiliary management method

Abstract

The present invention discloses an experimental teaching auxiliary management method, which is characterized in that the present invention is provided with at least one experimental signal management module and a presupposition experimental answer database microcomputer which is connected with the experimental signal management module, a signal collecting probe experiment signal processing module which is arranged on an input end correspondingly arranged close to each experimental facility processes the collected signal, and then transmits the collected signal after being deposing to a wireless transceiver circuit of an experiment end for sending, the input end of an experiment signal management module is provided with a wireless transceiver circuit of a management end, the received signal is transmitted to the experimental signal management module to process, and then is input to the microcomputer, which is compared with the correct answer in the experimental answer database, thus judging whether the experiment data is right, the experiment signal processing module sets up the channel serial number of each experimental facility by setting up a channel serial number generating device, the microcomputer judges the experimental facility corresponding to the received data signal through channel serial number, and the present invention has the advantages of collecting and managing the waveform of any output point of experimental waveform in the experimental facility in a real time way.

Description

technical field

[0001] The invention relates to a teaching assistant management method, in particular to an experiment teaching assistant management method. Background technique

[0002] Experimental teaching is an important auxiliary means of theoretical teaching in colleges and universities. Serious operation and high-quality completion of experiments are very important for students to master theoretical knowledge and cultivate practical ability. In many experimental course teaching in engineering colleges, one or two students are usually arranged Operate one experiment box, set up dozens of experiment boxes in an experiment classroom, and conduct experiments by changing different experimental modules of the experiment box according to different experiment contents. In the experiment, students are required to use an oscilloscope to observe the experimental waveform output by each point in the experimental equipment And make a record, and submit the experiment report to the...

Examples

Embodiment 1

[0028] Embodiment one: a kind of experimental teaching auxiliary management method, take mobile communication experiment as example, as shown in Figure 1, Figure 3, Figure 4, Figure 8, Figure 9 and Figure 10, it is realized by the following device: An experimental signal processing module 1 is arranged next to 30 experimental devices in a laboratory. The experimental signal processing module 1 includes an experimental signal preprocessing circuit 11, a high-speed A / D conversion circuit 12 and an experimental end data signal processing circuit 13. The input end of the preprocessing circuit 11 is connected with the signal acquisition probe 4, the output end of the experimental data signal processing circuit 13 is connected with the experimental end wireless transceiver circuit 5, and the signal acquisition probe 4 includes a ground terminal 41 and a signal acquisition end 42, respectively with plastic A metal alligator clip with a handle, the experimental signal preprocessing cir...

Embodiment 2

[0030] Embodiment two: other is identical with embodiment one, and difference is that experiment end data signal processing circuit 12 also comprises model is EPM240 programmable logic device and model is K6R1008V1D-J10 high-speed static RAM, the ground terminal 41 of signal acquisition probe 4 and The signal acquisition terminal 42 adopts a retractable metal hook with a plastic sleeve, and the wireless transceiver circuit 5 of the experiment terminal and the wireless transceiver circuit 7 of the management terminal are both wireless transceiver modules PTR4000. The process of shaping and driving the signal after the experimental signal preprocessing circuit is processed includes a data buffering process and a data reading process, and the data buffering process includes the following steps: (1) initializing the single-chip microcomputer and the high-speed A / D conversion circuit; 2) Read the DIP switch, and determine the current transmission channel of the experimental end wire...
