Description

Intelligent electric opening and closing device for a swing door The present invention relates to an intelligent electric opening and closing device for a hinged door, and more specifically, to an electric opening and closing device for a hinged door capable of automatically opening and closing the hinged door by detecting the approach of a person. The keywords for the task of this invention relate to new growth source technology, intelligent information, and the Internet of Things. It relates to an embedded-based distributed control system technology that connects a physical environment and a virtual environment by combining a mechanical device equipped with a sensor and an actuator—which is a cyber-physical system technology—with an information and communication infrastructure that controls it, thereby monitoring the physical environment in real time to collect, analyze, and process a large amount of data, and automatically controlling a physical mechanical device or computing device based on this data. Generally, various devices that automatically open and close doors are known. For example, devices for opening and closing a sliding door installed in an elevator are known, as described in Korean registered patent No. 10-1741220 (door opening and closing device for automatic elevator equipment, registered on May 23, 2017). However, in the case of hinged doors, it is difficult to use an automatic opening and closing method due to the risk of safety accidents caused by collisions when opening. In the case of sliding doors, they are difficult to apply to general living spaces such as homes or offices because a wider space (such as the area where the door is stored) must be secured for opening and closing. In addition, while automating hinged doors can improve convenience for the movement of people or objects (such as robots), there were limitations to automation due to issues such as difficulty in controlling the opening speed and angle depending on the installation environment, and the potential for posing a threat to people on the opposite side depending on the direction of opening and closing. In addition, conventional methods for opening and closing doors include using buttons or automatically opening and closing doors by detecting moving human bodies or objects. However, conventionally, since opening and closing control was based on moving objects, there was a limitation in that accurate detection was difficult when the movement was very slow or when the object was stationary. FIG. 1 is a block diagram of an electric opening and closing device for a hinged door according to a preferred embodiment of the present invention. FIGS. 2 and FIGS. 3 are examples of applications of the present invention. Figure 4 is a block diagram of the first recognition unit. FIG. 5 is a block diagram of the opening and closing control unit applied to the present invention. FIG. 6 is a configuration diagram of the opening and closing device part applied to the present invention. FIGS. 7 to 9 are example diagrams of a hinged door in a closed state, a first direction toward the outside, and a second direction toward the inside, respectively. To fully understand the structure and effects of the present invention, preferred embodiments of the present invention are described with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms and various modifications can be made. The description of the embodiments is provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention. In the attached drawings, components are depicted enlarged from their actual size for convenience of explanation, and the proportions of each component may be exaggerated or reduced. Terms such as 'first' and 'second' may be used to describe various components, but said components should not be limited by said terms. These terms may be used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, 'first component' may be named 'second component,' and similarly, 'second component' may be named 'first component.' Furthermore, singular expressions include plural expressions unless the context clearly indicates otherwise. Unless otherwise defined, terms used in the embodiments of the present invention may be interpreted in the sense commonly known to those skilled in the art. Hereinafter, an electric opening and closing device for a hinged door according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of an electric opening and closing device for a hinged door according to a preferred embodiment of the present invention, and FIG. 2 and FIG. 3 are diagrams of the use state of the present invention.
