Description

Apparatus for Open Circuit Detection and Operating Method Thereof The present disclosure relates to a circuit open circuit detection device and method. In complex electrical circuit systems such as those found in automobiles or aircraft, it is essential to continuously monitor the flow of current to detect electrical faults, such as open circuits. Conventional open circuit detection systems primarily operate by measuring the current and comparing it to a preset fixed value. However, this approach has limitations in that it fails to adequately account for various environmental factors, such as circuit configuration, voltage conditions, and wire resistance. Consequently, problems arise where changes in current are mistaken for open circuits, or conversely, actual open circuits are not properly detected. Furthermore, existing methods struggle to detect open circuits in sections where current is not measured. For instance, if an open circuit occurs in a specific section of the circuit, it may fail to be detected in other areas, potentially compromising system reliability. Consequently, there is a need for technology that expands the detection range across the entire circuit and, moreover, enables accurate detection of circuit open circuits under various environmental conditions. The information described above disclosed in the background technology of this invention is intended only to enhance understanding of the background of the present invention and may therefore include information that does not constitute prior art. The following drawings attached to this specification illustrate preferred embodiments of the present invention and serve to further enhance understanding of the technical concept of the present invention together with the detailed description of the invention provided below; therefore, the present invention should not be interpreted as being limited only to the matters described in such drawings. FIG. 1 illustrates a block diagram of a circuit open circuit detection device according to an embodiment of the present invention; FIG. 2 illustrates an operation flowchart of a circuit open circuit detection method according to an embodiment of the present invention; Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings. Instead, based on the principle that the inventor may appropriately define the concepts of terms to best describe his invention, they should be interpreted in a meaning and concept consistent with the technical spirit of the present invention. Therefore, it should be understood that the embodiments described in this specification and the configurations illustrated in the drawings are merely some of the most preferred embodiments of the present invention and do not represent all of the technical spirit of the present invention; thus, various equivalents and modifications that can replace them may exist at the time of filing this application. Furthermore, as used in this specification, "comprise" or "include" and/or "comprising" or "including" specify the presence of the mentioned features, numbers, steps, actions, parts, elements, and/or groups thereof, and do not exclude the presence or addition of one or more other features, numbers, actions, parts, elements, and/or groups. In addition, when describing embodiments of the present invention, "may" and "may be" may include "one or more embodiments of the present invention." Additionally, to aid in understanding the invention, the attached drawings are not drawn to actual scale, and the dimensions of some components may be exaggerated. Furthermore, the same reference numerals may be assigned to identical components in different embodiments. The statement that two subjects of comparison are 'identical' means that they are 'substantially identical.' Therefore, substantial identity may include deviations considered low in the industry, for example, deviations within 5%. Additionally, the statement that a parameter is uniform in a given area may mean that it is uniform from an average perspective. Although terms such as "first," "second," etc., are used to describe various components, it goes without saying that these components are not limited by these terms. These terms are used merely to distinguish one component from another, and unless specifically stated otherwise, the first component may also be the second component. Throughout the specification, unless specifically stated otherwise, each component may be singular or plural. The fact that any configuration is placed on the "upper (or lower)" of a component or on the "upper (or lower)" of a component may mean not only that any configuration is placed in contact with the upper (or lower) surface of said component, but also that another configuration may be interposed
