Description

Integrated Management System and Method of House Consuming Electric Energy The present invention relates to a system and method capable of efficiently managing electricity consumed in a household. Specifically, it involves measuring and analyzing electricity usage in the household in real time to provide the user with data on the current status of electricity usage and the remaining amount of electricity available for future use, preventing unnecessary power leakage by cutting off standby power, detecting abnormal temperatures within the distribution panel caused by sudden surges in electricity usage or equipment malfunctions to identify abnormal usage patterns and provide advance warnings to the user of dangerous conditions, and detecting fuel gas leaks within the household to warn the user, thereby achieving effects such as reducing electricity consumption and preventing electrical disasters. Furthermore, based on an analysis of electricity usage patterns within the household, it enables active participation in a demand response trading management system in a manner that minimizes inconvenience in daily life, thereby efficiently achieving electricity usage reduction targets. This relates to a "system for integrated management of household electricity consumption and a method for integrated management of household electricity consumption using the same," which enables public safety, better convenience, and the realization of carbon neutrality through greenhouse gas reduction. With the increasing variety of household electronic devices and the proliferation of smart homes, standby power consumption is on the rise. Previously, the mandatory installation of standby power cutoff devices was legalized under the Energy Conservation Design Standards, leading to the installation of standby power cutoff outlets in numerous multi-unit dwellings, such as apartment buildings. Prior technologies related to standby power cutoff outlets are disclosed in documents such as Korean Registered Patent No. 10-1848015. However, these conventional standby power cutoff outlets were not widely adopted due to their inconvenience of use; consequently, households are currently unable to cut off standby power and enjoy the associated benefits. Meanwhile, the proliferation of various electronic devices has led to a corresponding increase in household electricity consumption, resulting in several problems. First, the rise in electricity usage is increasing the risk of fires within distribution panels installed in each home. However, there is currently a lack of technology to effectively prevent such fires in household distribution panels. Another problem resulting from the increase in household electricity consumption is the rising costs per household. As electricity usage increases, the number of households subject to the government-mandated progressive electricity pricing system is growing, and consequently, the electricity bills that each household must bear are rising significantly. FIG. 1 is a schematic block diagram showing the configuration of a household power consumption integrated management system according to the present invention. FIG. 2 is a schematic block diagram corresponding to FIG. 1 showing the configuration of a household power consumption integrated management system according to the present invention linked with a demand response transaction management system. The present invention will be described below with reference to the attached drawings. This description is intended to illustrate preferred embodiments of the present invention and does not limit the technical concept, core configuration, and operation of the present invention. In particular, combinations of each block of the block diagram and each step of the flowchart attached to this specification may be executed by computer program instructions (execution engines). Since these computer program instructions may be loaded into the processor of a general-purpose computer, a special-purpose computer, or other programmable data processing equipment, the instructions executed through the processor of the computer or other programmable data processing equipment create means for performing the functions described in each block of the block diagram or each step of the flowchart.
