Reliable control circuit applied to direct-current electromagnet control mechanical arm

Abstract

The invention relates to the technical field of electromagnets, and particularly discloses a reliable control circuit applied to a direct-current electromagnet control mechanical arm. The reliable control circuit comprises a weak current control unit, an analog and digital hybrid processing circuit and a low-voltage direct-current electromagnet, wherein the weak current control unit sends a control signal to the analog and digital hybrid processing circuit; the analog and digital hybrid processing circuit processes the control signal and sends the processed control signal to the low-voltage direct-current electromagnet; the low-voltage direct-current electromagnet generates a feedback signal according to the processed control signal and sends the feedback signal to the analog and digital hybrid processing circuit for processing; and the analog and digital hybrid processing circuit sends the processed feedback signal to the weak current control unit. The control circuit between the weak current control unit and the low-voltage direct-current electromagnet is distinguished, signal interference between the weak current control unit and the low-voltage direct-current electromagnet is reduced, and the real-time performance and reliability of work of the whole system are improved.

Description

technical field [0001] The invention relates to the technical field of electromagnets, and more specifically, relates to a reliable control circuit for the application of DC electromagnets to control mechanical arms. Background technique [0002] Definition of electromagnet: It is a device that generates electricity when it is energized; a conductive winding that matches its power is wound outside the iron core. This coil with current is magnetic like a magnet, and it is also called an electromagnet (electromagnet); We usually make it into a strip or hoof shape to make the iron core easier to magnetize; in addition, in order to demagnetize the electromagnet immediately after power off, we often use soft iron or silicon steel materials that demagnetize faster; such The electromagnet has magnetism when it is energized, and the magnetism will disappear after the power is turned off; the electromagnet is widely used in our daily life, and the power of the generator has been grea...

Problems solved by technology

For the control application circuit of the DC electromagnet, the current common control circuit and control method are relatively simple, there is no isolation between the control unit and the DC electromagnet, and the reliability is not high. Once the DC electromagnet side fails, the control unit will be damaged. Hidden danger

In addition, the electromagnet is an inductive component. If the control circuit design is not good, it will cause the level fluctuation of the control unit, resulting in abnormal operation of the entire system circuit or damage to components.
