Experimental education auxiliary management system

Abstract

This invention discloses an experimental teaching assistant management system including multiple experimental signal process modules, at least one management module and a microcomputer connected with it characterizing that the input of the process module is connected with a signal collection probe, the output of which is set with a wireless T-R circuit of the experimental end, the input end of the management module is set with a wireless T-R circuit communicating with that of the experimental end, the signal process module is set with a channel sequence number generation device, which is advantaged that waveforms of output points of any experimental waveforms in various teaching boxes can be collected and managed quickly and conveniently if only altering sampling positions of signal collection probes.

Description

technical field [0001] The invention relates to a teaching auxiliary management system, in particular to an experimental teaching auxiliary management system. 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 t...

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.
