Description

Direction control device and method for electronic equipment Technical Field The present invention relates to an electronic device direction control apparatus and method (APPARATUS AND METHOD FOR CONTROLLING THE DIRECTION OF AN ELECTRONIC DEVICE), and more particularly, to an electronic device direction control apparatus and method according to an input target rotation angle of an electronic device. Background The position and angle of an antenna (antenna) provided in a mobile communication base station (mobile communication base station), a lighting device provided in a stadium, and other electronic devices need to be determined according to an accurate design. For example, the setting position of the antenna is determined according to a network design (network design) result in consideration of coverage (coverage) and traffic (traffic). Also, since the mobile communication terminal and the communication intensity may vary according to the directional direction of the antenna, in order to eliminate a shadow area, the antenna for the base station is optimized by a tilting or steering operation of the antenna to adapt to the radio wave environment of a place where the antenna is provided. Wherein the steering angle of the antenna is determined by considering the sector orientation angle of the horizontal component of the beam and the tilt angle of the antenna is determined by considering the tilt angle of the vertical component of the beam. On the other hand, the tilt angle and the steering angle of the preset antenna may need to be readjusted corresponding to the change of the wireless environment. For example, the inclination of a mast supporting an antenna may be changed due to an external force such as strong wind or a jig for coupling the antenna to the mast is deviated, resulting in deviation of an inclination angle or a steering angle of the antenna, in which case there is a problem in that an operator needs to perform a direction measurement and alignment work with an expensive gauge in the field or the operator needs to climb to a high position where the antenna is provided to adjust the orientation direction of the antenna. Further, even if the operator adjusts the orientation direction of the antenna by operating the external controller without climbing to the antenna installation position, there is a problem in that the orientation direction of the antenna cannot be accurately readjusted because the orientation direction of the antenna is adjusted by rough estimation. Korean laid-open patent publication No. 10-2022-0079788 (2022, 14 th year 06) (hereinafter, referred to as "prior art") discloses a "method and system for managing an orientation direction of an antenna of a mobile communication base station", which is a technique that enables an operator to accurately readjust the antenna orientation direction without having to climb to an antenna installation position. The prior art is an antenna management system including a direction control device for controlling a directional direction of an antenna of a mobile communication base station, the direction control device including a data receiving part for receiving spatial direction information of the antenna device from a measuring device or capturing video data of a foreground of the antenna device's direction, and a control part for controlling a tilting and steering unit of the antenna device using at least one of the spatial direction information and the video data so that the antenna device has a preset target spatial direction. However, the above-described prior art needs to have a plurality of photo sensors to measure the orientation direction of the antenna device using the incident angle of the sunlight, and thus has a problem of increased cost. Disclosure of Invention Technical problem The technical problem of the present invention is to provide a direction control apparatus and method of an electronic device configured such that when an operator inputs a target rotation angle of the electronic device to a controller, the electronic device automatically rotates to the target rotation angle, thereby saving costs. The technical problems of the present invention are not limited to the above-described problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description. Solution to the problem In order to achieve the above-described object, a direction control device for an electronic apparatus according to the present invention includes a motor, a sensor, and a control unit. The motor adjusts a rotation angle of the electronic device, the sensor detects a current rotation angle of the electronic device, and the control unit operates the motor to rotate the electronic device from the current rotation angle to the target rotation angle when the target rotation angle of the electronic device is input. The electronic device may be provided on a pillar standing on the ground and dispos
