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...

Problems solved by technology

But above-mentioned this invention also has some defects, at first its complete machine structure is too complicated, and cost is higher, and there is not fixed experimental data output interface in the various experimental boxes that domestic manufacturer produces at present, this is because in experiment During the process, different experimental contents need to observe the experimental waveforms of different output points. The positions of the output points of these experimental waveforms on each experimental module are different, so it is impossible to have a common data output interface suitable for the experimental content of each unit. Therefore, the scope of application of this invention is very small, and it cannot be suitable for experimental equipment produced by any manufacturer; secondly, both the microprocessor MCU and the teacher's terminal server need to be connected to the experimental network through a network interface, which belongs to a wired connection, and there are dozens of them in the classroom. The experimental equipment needs to be equipped with dozens of network cables. In addition to the complicated technology and high cost, it also has the defect that the overall experimental environment is relatively messy due to too many connecting lines in the laboratory.
