Pre-amplification circuit based intelligent control system for roller-blind door

Abstract

The invention discloses a pre-amplification circuit based intelligent control system for roller-blind door. The system is characterized by mainly comprising a central processor, an A / D converter, a door opening control circuit, a door closing control circuit, a pre-amplification circuit, a photoelectric sensor, an infrared sensor, a door opening motor and a door closing motor, wherein the A / D converter, the door opening control circuit and the door closing control circuit are connected with the sensor processor, the pre-amplification circuit is connected with the A / D converter, the photoelectric sensor and the infrared sensor are connected with the pre-amplification circuit, the door opening motor is connected with the door opening control circuit, and the door closing motor is connected with the door closing control circuit. The intelligent control system is simple in structure, low in cost and capable of automatically opening and closing the door; and thus, the product and production environment in the roller-blind door can be ensured, and the intelligent control system is suitable for popularization and application.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an intelligent control system for rolling shutter doors based on a preamplifier circuit. Background technique [0002] Due to the needs of production and processing, factories usually use rolling doors to isolate products from the production environment. The rolling doors currently used are usually electric rolling doors. The electric rolling shutter door is opened and closed by the forward and reverse of the single-phase motor controlled by the relay, that is, the door is opened by the up button, the door is closed by the down button, and the door is stopped by the stop button. Since the electric rolling doors are controlled by human actions, there are often situations where the door is forgotten or not closed due to anxiety, so it is easy to cause harmful pollution such as noise, dust or smoke to enter the rolling door, thereby affecting the products or the production environment ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects that currently used electric rolling doors rely on manual actions to control the switch, and often forget to close the door or fail to close the door due to anxiety, so that harmful pollution such as noise, dust or smoke easily enters the rolling door, and provides a An intelligent control system for rolling doors based on a preamplifier circuit that is not only simple in structure, but also low in cost, and can also close the rolling doors in time
