Problems solved by technology

For this type of experimental system, students have to read the signal amplitude, time value and other data from the oscilloscope with the naked eye when doing the experiment. The error is relatively large. Some experiments can only be done qualitatively, and it is not convenient to divide and organize the experimental data.
[0003] Generally speaking, there are not many products specially used for self-control experiments. Most of the products that have been sold in the market for many years generally have: the operation is not convenient enough; students cannot focus on the self-control principle embodied in the experiment; The experimental class requires a lot of class hours; there is no simulation function...etc.

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0028] As shown in Figure 2, the experimental instrument of this automatic control principle mainly includes a PC, mainly including the function module of LabView, which is used to play the functions of virtual oscilloscope and virtual signal generator after being connected with the main module; a set of structure The same small modules are used to connect the required components to form various links; a main module mainly includes switching power supply, AD / DA module and serial port communication module; among them, the function module of LabView generates the source signal through the serial port The communication module is sent to the main module and converted into an analog signal by the AD / DA module. After being amplified, the output signal is converted into a digital signal by the AD / DA module through the experimental box composed of a gr...

Abstract

This invention relates to one experiment device and method of automatic control principles, which comprises the following parts: one PC with LabView function module as virtual wave display and virtual signal generator function after connection with main module; one set of same function module to form each process of parts needed; one main module composed of switch power, AD / DA module and series communication module to generate source signal to it and to convert the module into analogue signal to form experiment box for digital signal to PC machine into digital signals.

Description

technical field [0001] The invention relates to the field of experimental teaching instruments, mainly an experimental instrument and method based on the principle of automatic control, which can be widely used in control engineering majors, automation majors, mechanical majors, instruments and meters in various schools (mainly colleges and universities). Course teaching experiments of "Automatic Control Principles" or "Control Engineering" or "Signals and Systems" for similar majors. Background technique [0002] Most of the structure diagrams of the experimental system of the existing automatic control principle are shown in Figure 1. For this type of experimental system, students have to read the signal amplitude, time value and other data from the oscilloscope with the naked eye when doing the experiment. The error is relatively large. Some experiments can only be done qualitatively, and it is not convenient to divide and organize the experimental data. . [0003] Gene...
