Door system and door closer using electro-reholigical fluid/magneto reholigical fluid and control method thereof

The present invention, ER / MR breakdown of the fluid by applying an ER / MR fluid, causing the MR phenomenon under the application of electric or magnetic field to the door closer on the ER / using MR fluid door closer and therefore the door system and the control according to how one to control the stress of the door, it is possible to adjust the closed-rate, as well as to secure the door at any opening angle during opening of the door, allow continuous control of the door to facilitate the dog, pyesi timing of the door the more complex structure and manual door for easy access for room ventilation or chulipja and, thereby semi-automatic doors, can be solved at the same time, the hassle of the lungs, by applying the sensor according to the speech, object detection or weather of chulipja one of the doors, as well as possible, the lungs, the automatic door of the piece by having a separate remote controller, the lungs as possible using the ER / MR fluid Serves to provide air enclosure and a door system and a control method according thereto, and the technical configuration of the door is equipped with two, or more, at least one in place of the door and the door frame so that the waste can be connected to the door frame, which is installed in the wall with door and in the door closer for connecting the door frame, a disc shape having a predetermined installation space therein, the outer side is installed in the disk-shaped body shaped to be coupled to a central through-hole connection formed to protrude to the upper disc; Doedoe sapseol the installation space of the outer disk, an inner disk which is a rotational axis of the rod-like body circle-like connected in an upward direction in the center; And a rheological fluid which is filled in the installation space of the outer disk; It characterized by comprising a composition including. Door closure, ER fluid (Electro-Reholigical Fluid), MR fluid (Magneto Reholigical Fluid), sensors, yield stress
