1. A door locking control system having a door and a door frame, the door locking control system comprising:
an armature coupled to the door or the door frame to which the door is coupled;
a first magnetic body rotatably mounted in the door or the door frame;
a magnetic module provided on the door or the door frame to face the armature and brought into contact with or separated from the armature by direction change of a magnetic force occurring due to rotation of the first magnetic body provided inside of the magnetic module;
a detector configured to detect an open state or a closed state of the door; and
a controller electrically connected to the detector and configured to control the magnetic module according to the open state or the closed state of the door detected by the detector, wherein the magnetic module includes:
a base plate including a first side to which the first magnetic body is rotatably coupled;
a first contact portion extending from a second side of the base plate to an armature side;
a second contact portion extending from the first magnetic body to the armature side; and
a second magnetic body provided between the first contact portion and the second contact portion to be connected with the first contact portion and the second contact portion,
wherein in response that the first magnetic body rotates, the first contact portion and the second contact portion are in contact with the armature or separated from the armature by the direction change of the magnetic force.
