The present invention relates to a measurement device capable of measuring energy of each electronic appliance and load. According to the present invention, an energy measurement device at the penetration point of power includes: a power data collection unit which collects power data about a plurality of load components including a power signal at least at one penetration point of power; an operation status extraction unit which identifies a normal state or an excessive state of power change from the collected power data and extracts the operation status or a change pattern of the operation status of a concerned load component; and a dataset generation unit which generates a dataset for each individual load component matched to the operation status or to the change pattern of the operation status using a signal correlation according to the power consumption feature of the concerned individual load component. According to the present invention, since it is easy to extract data from total electric energy data to energy consumption data of an individual load component using a single sensor and a single energy measurement device, active expansion of an energy-saving solution infrastructure is available. Also by removing a burden of implementing an expensive system due to addition of a plurality of individual energy monitoring devices and node circuit measurement devices, the present invention enables rapid expansion and realization of a monitoring-based energy-saving market. Furthermore, by combining a measurement device in which a hardware algorithm is mounted and a cloud which executes a software algorithm, time delay due to complicated operations can be prevented, and necessary resources and traffic can be reduced. |
