IOT-based industrial control system

Abstract

The invention discloses an IOT-based industrial control system. The IOT-based industrial control system comprises a signal receiving circuit, a signal calibration circuit and a voltage-stabilizing output circuit; the signal receiving circuit receives signals of the input end of a signal transmission channel for a control terminal in the IOT-based industrial control system; the signal calibration circuit is divided into two channels for receiving output signals of the signal receiving circuit; one channel detects abnormal high-level signals by using a composite circuit composed of an audion Q1and an audion Q2; the other channel performs same-phase amplification by using an operational amplifier AR1; after same-phase amplification is carried out by the operational amplifier AR1, signals arerespectively amplified through an operational amplifier AR2 and attenuated through a variable resistor RW1; finally, after performing same-phase amplification by using an operational amplifier AR5, the voltage-stabilizing output circuit performs output after stabilizing voltage through a voltage-stabilizing circuit composed of an audion Q5 and a voltage-stabilizing tube D4; signals can be automatically calibrated; signal stability can be ensured; and thus, signal disturbance is prevented.

[0002] With the development of computer technology, communication technology and control technology, the traditional control field is undergoing an unprecedented change, and it has begun to develop in the direction of networking. The change of industrial control systems is particularly obvious, from traditional semi-manual to fully automatic The evolution of the control system has even led to the emergence of unmanned factories, which have realized a highly intelligent control system. However, in the actual use of the system, due to cost issues, not all factories are suitable for highly intelligent control systems, and some On the basis of the automated industrial control system, the working performance of the factory is not as good as that of the highly intelligent control system, but it is more suitable for some small and medium-sized factories. However, such industrial control systems often have network delays and disorder in the signal transmission process.
