Intelligent control system for roller shutter door based on signal processing type selection circuit

Abstract

The invention discloses an intelligent control system for a roller shutter door based on a signal processing type selection circuit. The intelligent control system is characterized by consisting of an A / D converter and a selector circuit connected to a central processor, a signal filter circuit connected to the A / D converter, a front amplifier circuit connected to the signal filter circuit, a photoelectric sensor and an infrared sensor connected to the front amplifier circuit, a door opening control circuit and a door closing control circuit connected to the selector circuit, a door opening motor connected to the door opening control circuit, and a door closing motor connected to the door closing control circuit. The intelligent control system is simple in structure, is low in cost, is capable of automatically opening and closing the door, is capable of ensuring that the roller shutter door is isolated from a production and a production environment, and is suitable for being popularized and applied.

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 processing type 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 pro...
