Signal filtering circuit-based intelligent control system for roller shutter door

Abstract

The invention discloses a signal filtering circuit-based intelligent control system for a roller shutter door. The intelligent control system is characterized in that the system mainly comprises a central processing unit, and an A / D converter, a door opening control circuit and a door closing control circuit which are connected with the 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 motor connected with the door opening control circuit, and a door closing motor connected with the door closing control circuit. The intelligent control system is simple in structure and low in cost, can also automatically open and close the door, and thus can ensure that the roller shutter door isolates products and production environment, and 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 signal filter circuit. Background technique [0002] Due to the needs of production and processing, factories usually use rolling shutters to isolate the product and the production environment. The current rolling shutters are usually electric rolling shutters. Electric rolling doors are controlled by a relay to control the forward and reverse rotation of a single-phase motor to complete the opening and closing of the rolling door, that is, the door is opened by the up button, the door is closed by the down button, and the door action is stopped by the stop button. Since electric rolling shutters are controlled by human actions, it is often the case that they forget to close the door or fail to close the door due to anxiousness. Therefore, it is easy to cause harmful pollution such as noise, dust or smoke to enter the rol...
