20110153107 | APPARATUS AND METHOD FOR SMART ENERGY MANAGEMENT BY CONTROLLING POWER CONSUMPTION - Disclosed are an apparatus and a method for smart energy management by controlling power consumption. Power consumption information is collected from one or more electrical device groups with a smart meter and electrical devices connected through gateways. When the method estimates that the power consumption will be larger than a threshold value, a control command is outputted to a load controller connected through the gateway and power consumption of electrical devices that belong to the electrical device using group is remotely controlled. According to an embodiment of the present invention, an energy company that produces and supplies energy can supply energy depending on a consumer's demand by using current facilities because the present invention can collect remotely energy consumption, analyze energy consumption patterns, and control automatically the energy consumption of electrical devices installed in a customer's area. The consumer who consumes energy can save the energy consumption and the charge of the energy consumption. | 06-23-2011 |
20120159211 | APPARATUS AND METHOD FOR MANAGING POWER EQUIPMENT IN ADVANCED METERING INFRASTRUCTURE NETWORK - Provided is an apparatus and method for managing a power equipment in an advanced metering infrastructure (AMI) network included in a smart grid network. According to an aspect of the present invention, an apparatus and method for managing a power equipment in an AMI network may provide a load control environment enabling a power equipment to declare an opt-out when another power equipment declares an opt-out by providing a list of power equipments included in a load control group in response to a power equipment declaring an opt-out of the load control group so as to process an opt-out of a power equipment selected from the list. | 06-21-2012 |
20130285835 | METHOD AND APPARATUS FOR DATA MANAGEMENT IN ADVANCED METERING INFRASTRUCTURE NETWORK - A method for transmitting, storing and managing data by compressing data packets to be transmitted and received over an advanced metering infrastructure (AMI) network with low-capacity memory and low-transfer rate. A number of transmission packets may be reduced using at least one of a bitmap interval algorithm that assigns a bitmap value to each interval, thereby reducing a number of request packets, a repeated-bitmap interval algorithm that represents sequential data values as bitmap values by toggling a bit value between 0 and 1 in each data value when a change occurs in the sequential data values, and a run-length encoding algorithm that compresses data by encoding run length of sequential identical data. | 10-31-2013 |
20130304423 | HIGH ENERGY EFFICIENCY SENSOR NODE AND OPERATING METHOD THEREOF - A high energy efficiency sensor node and an operating method thereof are provided. The high energy efficiency sensor node may include a sensing unit to generate sensed information and to store the sensed information in a database when a set period commences, and a control unit to obtain n pieces of sensed information corresponding to n periods from the database, and to transmit the n pieces of sensed information obtained to a first neighbor node when the n periods elapse. | 11-14-2013 |
20130311558 | PROFILE-BASED WIRELESS SENSOR NETWORK SYSTEM AND COMMUNICATION METHOD - In a sensor network system including at least one sensor node and at least one actuator node, a group is formed based on attribute of each node. Sensing data is shared among the nodes in the group, and each node performs autonomous processing to process an event by comparing the sensing data with a preset event threshold value. | 11-21-2013 |
20130320864 | METHOD OF CONTROLLING LIGHTS AND SYSTEM FOR MANAGING LIGHTS USING THE SAME - In a light-installed area where a plurality of lights are installed, a light managing system senses a moving object that enters the light-installed area and predicts an predicted stop position of the moving object based on record information on a channel of movement corresponding to identification information on the moving object. The light managing system calculates a predicted channel of movement of the moving object based on the predicted stop position, and selects lights to be driven based on the calculated predicted channel of movement. The light managing system turns on the selected lights. | 12-05-2013 |
