Technical Field

The invention relates to the technical field of circuits, in particular to a control system for AI bag breaking and box body judging and classifying accuracy based on garbage identification.

Background

At present, along with the popularization of garbage classification, garbage can products bloom all the time, but the control mode of a garbage can putting-in door mainly comprises 3 types: the stepping motor is manually opened and closed, the single chip microcomputer controls the stepping motor to be opened and closed, and the single chip microcomputer controls the direct current motor to be opened and closed. The direct current motor control box door is opened and closed, and the direct current motor positive and negative rotation and speed regulation technology is related, and the direct current motor positive and negative rotation control and speed regulation method in the current market mainly comprises the following steps:

the double-pole double-throw switch is manually controlled and has no speed regulation function

And the H bridge is controlled by an electronic circuit, has a speed regulation function controlled by a single chip microcomputer and does not have isolation.

The H bridge is controlled by an electronic circuit, has optical coupling isolation and can be controlled by a single chip microcomputer to regulate speed

Among them, the disadvantages are as follows:

firstly, the double-pole double-throw switch is manually controlled, the speed can not be regulated by a single chip microcomputer, the motor is manually switched to rotate forwards and reversely, the double-pole double-throw switch is slightly clumsy, and the double-pole double-throw switch is obviously not suitable for garbage can products.

Secondly, although speed regulation can be realized, the motor is an inductive load and is easy to generate radio interference, so that the system of the single chip microcomputer is not stable enough. The single chip microcomputer and the motor can not share a power supply, so that the application range of the motor is limited, and the motor is not suitable for garbage can products.

The singlechip and the motor power supply are isolated, and the speed regulation is realized, but the cost is high, the peripheral circuit is complex and easy to damage because 4 MOS tubes are adopted as H bridges, and the damaged items are not easy to maintain and replace on site; on the other hand, effective speed regulation is realized, the motor must be provided with a speed measuring device to realize closed-loop speed regulation, and the product cost is greatly improved. Otherwise, if the speed is regulated by the open loop, the resistance is different due to inconsistent tightness when the box door is installed, the same target speed is set, and possible box doors can normally run, some box doors can be jammed and cannot run, the production operability is poor, and the dustbin is not applicable to dustbin products.
