Abstract:
PURPOSE: A data transmission system for monitoring a passenger room in real time using a VDSL(Very high-data rate Digital Subscriber Line) transmission method between an engine room and a passenger room in a subway train is provided to build a VDSL network using an existing interphone telephone network installed in the train. CONSTITUTION: A camera(102) takes an image of high definition for monitoring a passenger room in a subway passenger room in real time. A VDSL modem(100) transmits passenger room monitoring video data which is photographed by the camera. A VDSL concentration device(110) receives the passenger room monitoring video data from the VDSL modem in a subway engine room. A mobile wireless transmission device(112) transmits the passenger room monitoring video data, which is transmitted to the VDSL concentration device in the engine room, to a ground wireless transmitting device.

Abstract:
PURPOSE: A subway-room congestion control service using a wireless network is provided to enable passengers to select a subway-room by the congestion information. CONSTITUTION: A base station(350) restores sensing information composed of intelligent cameras, sensor units, and gateways and transmits the stored information. A subway-room congestion level informing server checks the congestion level of a subway-room based on the sensed information which is transmitted from the base station. Display boards(371-374) indicates the subway-room congestion level which is from the subway-room congestion level informing server.
Abstract:
PURPOSE: A system for monitoring an inside of a passenger car is provided to confirm rapidly a dangerous state by utilizing voice and images. CONSTITUTION: A plurality of microphones(M1-M4) are used for receiving the sound from an inside of a passenger car. A voice analysis module is used for transmitting a dangerous state confirmation signal by analyzing the sound received through the microphones. A state determination module is used for photographing images in a dangerous state by using a camera(20) when the dangerous state confirmation signal is received from the voice analysis module. The state determination module guides a present state and performs an alarm operation.

PURPOSE: A method for indicating gps coordinate positions in a design drawing is provided to confirm a location on a design drawing by displaying a satellite signal, received from a GPS receiver in a construction field, on the design drawing. CONSTITUTION: Surrounding landmarks and construction information are computerized by using the Bessel coordinate system(S1). A design drawing is inputted into the terminal(S2). GPS coordinate positions are received from a satellite(S3). The received coordinate positions are converted into the Bessel coordinate positions(S4). The design drawing in correspondence with the converted Besssel coordinate positions are searched(S5). The searched design drawing is outputted on a screen of a terminal(S6). The coordinate positions are displayed on the outputted design drawing(S7).
