Abstract:
PURPOSE: A system and a method for metadata management are provided to manage data through a memory and permanently store the data, thereby quickly responding to a request of a user. CONSTITUTION: A command converting unit(130) converts a received service request into a data structure of a system. A chain managing unit(150) uses a plurality of handlers to process the converted service request. A directory service unit(170) stores a part of metadata. The directory service unit searches and manages the part.

Abstract:
Provided are an apparatus and a method for providing position information and gathering information using Radio Frequency Identification (RFID). The apparatus includes: a plurality of RFID tags, driven by a radio frequency transmitted from an RFID reader installed in the vehicle, for providing stored tag information in order to provide current position information to the vehicle; a plurality of sensor nodes for sensing the time point when the RFID tags are driven and transmitting the sensed information through a sensor network; and an information gathering server for gathering and processing the information sensed by the sensor nodes, where at least two RFID tags and one sensor node are configured in groups, and the groups are installed at predetermined intervals on each lane of a road.
Abstract:
A method and an apparatus for integrating heterogeneous sensor data in a ubiquitous sensor network are provided to perform integration of the heterogeneous sensor data for satisfying request items of plural users of a sensor network management system operated on plural domains, thereby easily performing addition of the sensor network or sensor network management system. A method for integrating heterogeneous sensor data in a ubiquitous sensor network comprises the following steps of: receiving an integrated inquiry for heterogeneous sensor networks from a sensor network management system; separating the received integrated inquiry according to the sensor networks(610); transmitting the separated inquiry according to the sensor networks(614); if receiving a response to the inquiry from each sensor network, generating the received response as integrated sensor data and storing the generated integrated sensor data in an integrated database; and converting the integrated sensor data, stored in the integrated database, into a preset data format and transmitting converted data to the sensor network management system(616).
Abstract:
A location and direction guide system for blind persons and a method thereof are provided to enable visually disabled persons to wander conveniently and safely by grasping the location of a blind person's stick, to which an RFID(Radio Frequency Identification) tag is attached, through an RFID reader, installed at a public area, such as subway, and a department, and providing him information about his location and proceeding direction through a mobile terminal. An RFID reader, installed in a subway, recognizes an RFID tag attached to a blind person's stick and deciphers the information of the RFID tag(201). A blind person information inquiry server obtains the blind person's information corresponding to the deciphered RFID tag information from a blind person information database(202) and delivers the obtained information to a location tracking server and an ARS server(203). The ARS server, based on the delivered information, automatically makes a call to the blind person's mobile terminal and provides a voice menu so that the blind person can select whether to use an equipment in the subway or to take a subway train(204,205). In case the blind person inputs desired subway route information through his mobile terminal in order to take a subway train, the ARS server delivers the inputted information to the location tracking server(206,207). The location tracking server confirms the present location information of the blind person in real time, creates distance information to the blind person's destination in real time, and provides it to the ARS server. Based on the real-time location and distance information provided from the location tracking server, the ARS server provides a voice announcement through the blind person's mobile terminal so that he can safely arrive at his destination(208).
Abstract:
A mobile RFID(Radio Frequency IDentification) service agent device for vicariously processing RFID information of a mobile terminal and a method thereof are provided to reduce power consumption and a communication charge by minimizing network communication/operation of the mobile terminal, as a mobile RFID service agent vicariously processes the operation needed for using an RFID network service. A command interpreter(420) extracts a command and a parameter by parsing a command message received from the mobile terminal. A task processor(440) extracts and performs a related task module from a record corresponding to a task name which is one of the parameter in case that the extracted command is 'RunTask'. A response transmitter(470) transmits a performance result message of the task processor to the mobile terminal. The task processor registers the record corresponding to the task name in the case that the extracted command is 'AddTask', and updates or deletes the record corresponding to the task name in the case that the extracted command is 'UpdateTask' or 'DeleteTask'.
