Abstract:
Disclosed are an apparatus and a method for transmitting a tag. The apparatus for transmitting a tag converts 2 bits of a plurality of bit data into one symbol using phase information and orthogonal information. The apparatus for transmitting a tag generates a sub-carrier signal by multiplying the symbol by a square wave having a faster period by a predetermined number of times than a period of the symbol, and transmits the sub-carrier signal to a reader
Abstract:
A sensor tag includes: a tag chip that receives a supply of a driving voltage that is generated from a radio frequency (RF) signal that is received from a reader and that transmits sensor data to the reader according to a request from the reader; at least one sensor that receives a supply of a necessary driving voltage from the tag chip and that measures corresponding sensor data; and a micro controller unit (MCU) that receives a supply of a necessary driving voltage from the tag chip and that transfers sensor data that is measured from the at least one sensor to the tag chip.
Abstract:
Various embodiments for a RAN-Core converged mobile core network based on digital twin devices are disclosed. In one embodiment, a method of operating a network function included in a core network of a mobile communication system and implemented as an electronic device comprises generating a digital twin for a User Equipment (UE); and providing a network service for the UE in cooperation with at least one other network function based on the generated digital twin.
Abstract:
An apparatus for forecasting energy consumption includes a load data collection unit to collect low level data related to energy load data. The apparatus includes a filtering/attribute selection unit to eliminate duplicated attributes from attributes of low level data to produce an optimal attribute set. The apparatus includes a training unit produces a multi-class in which a plurality of single classes is hierarchically coupled in at least two levels and creates training data used for forecasting the energy consumption based on the produced multi-class. The apparatus includes a forecasting unit calculates the energy consumption to be forecasted on a basis of the real-time low level data, the multi-class and the training data. Therefore, it is possible to contribute to the progressive expansion and update of a cooling load forecasting system.
Abstract:
A gateway system for a sensor network and a driving method thereof are disclosed. The gateway system includes a sink node board that collects sensor data measured by a sensor node and transmits the sensor data, and a gateway board that transmits the sensor data transmitted from the sink node board to a server. Herein, the sink node board controls whether to apply power to the gateway board or not.
Abstract:
According to an exemplary embodiment of the present invention, a method for managing a resource using an apparatus for managing a resource is provided. The apparatus for managing a resource generates a first instance for a first community using a first ontology class about communities including at least one resource as a member according to a goal. The apparatus for managing a resource generates a second instance for a first resource using a second ontology class about resources. Further, the apparatus for managing a resource estimates a relation between the first instance and the second instance.
Abstract:
An integration framework system includes an interpreter configured to provide a general-purpose description and interpretation of a resource, a method, and a parameter regarding a hardware device on a network of things. An integration framework system includes an implementation binder configured to provide dynamic binding or dynamic unbinding depending on the change in the resource of the hardware devices.
Abstract:
Disclosed herein are an apparatus and method for managing the locations of service equipment for a plant factory. The apparatus includes a sensor registration management unit, a sensor ID issuance unit, and a location registration management unit. The sensor registration management unit performs a registration procedure that registers with a sensor network a plurality of service devices and sensors that are installed in the plant factory. The sensor ID issuance unit issues sensor IDs to the plurality of service devices and sensors registered with the sensor network, respectively. The location registration management unit performs a location registration procedure that registers information about the locations of the plurality of service devices and sensors based on the issued sensor IDs.
