Abstract:
PURPOSE: A sensor automation placement device for composing a building energy management system environment and a method thereof are provided to determine a position of a sensor in a building environment on a program, to confirm the sensor position, and to calculate a necessary budget for sensor composition based on information about a necessary budget for sensor placement, a feature of the sensor, and a space feature of a building. CONSTITUTION: An information input unit (110) receives information about a building in which a building energy management system is built, information about sensors used for building the building energy management system, and information about a budget for building the building energy management system. A sensor placement unit (120) calculates a placement position of the sensors based on the inputted information. A user interface unit (130) displays the calculated placement position.

Abstract:
PURPOSE: An electronic watt hour meter with a wide dynamic range is provided to expand the measuring range of a load current in the input range of an analog/digital converting part by turning off a part or whole of relay switches in connection with respect resistors. CONSTITUTION: A voltage converting part(110) is in parallel connection with power and detects a supplying voltage. Detected supplying voltage is converted to output a converted voltage. A current converting part(120) converts a supplying current, which is adjusted according to a controlling signal or detected according to a pre-set conversion ratio. A converted current is outputted. An analog/digital converting part(130) converts the converted voltage and the converted current into digital signals. A calculating and controlling part(140) calculates power and watt hour and controls conversion ratio by outputting a controlling signal to a current converting part.
Abstract:
An energy saving home gateway based on a network protocol and a control method thereof are provided to cut off power of a service function and a main processor of the home gateway when a service is not operated, thereby performing an energy saving function. A network interface function unit(600) performs a physical network interface function for an external network and a home network. A network protocol agent function unit(400) processes control traffic in an idle state when a service traffic does not exist. A power supply unit(500) supplies power to the network interface function unit, a memory(100) and the network protocol agent function unit in the idle state.
Abstract:
A system, a terminal and a method for power control are provided to control power about a function with an information home appliance device and a home network service and integrally perform power source control about all information home appliance devices connected to the home network and control power control about internal functions of the information home appliance devices. A power control system comprises a storage unit(15), a power control resource management unit(11), a power control command setting unit(12) and a network matching unit. The power control resource management unit receives power control element information from a power control terminal and stores the power control element information in the storage unit. And the power control resource management unit extracts detailed power control element information with a power control target device. The power control command setting unit generates a power control process to set a power control command based on the power control resource information and the power control element information.
