Embodiment

[0026] Such as figure 1 As shown, the intelligent control system of the present invention mainly consists of a central processing unit, an A / D converter connected with the central processing unit and a selection circuit, a signal filtering circuit connected with the A / D converter, and a signal filtering circuit connected with the signal filtering circuit. The photoelectric sensor and the infrared sensor connected with the circuit are composed of a door opening control circuit and a door closing control circuit connected with the selection circuit, a door opening motor connected with the door opening control circuit, and a door closing motor connected with the door closing control circuit. The infrared sensor is used to collect the human body signal outside the rolling shutter door. When someone wants to enter the rolling shutter door, the infrared sensor sends the collected human body signal to the A / D converter, and the A / D converter converts the signal collected by the infrar...

Abstract

The invention discloses an intelligent control system based on a signal filtering type selection circuit and used for a roller shutter door. The intelligent control system is characterized by comprising an A / D (analog / digital) converter and a selection circuit which are connected with a central processing unit, a signal filtering circuit connected with the A / D converter, a photoelectric sensor and an infrared sensor which are connected with the signal filtering circuit, a door opening control circuit and a door closing control circuit which are connected with the selection circuit, a door opening motor connected with the door opening control circuit as well as a door closing motor connected with the door closing control circuit. The intelligent control system is simple in structure, low in cost, suitable for popularization and application and capable of opening and closing the door automatically so as to ensure that products and a production environment are separated by the roller shutter door.

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 signal filtering selection 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 productio...
