A system for displaying linear data and monitoring a state of a train signal device is provided to minimize damage by rapidly informing a state or trouble of a train signal device to a manager through a portable terminal. A system for monitoring a train signal device includes a sensor node(1), a USN(Ubiquitous Sensor Network) node(2), a reader system(3), and a web server(4). The sensor node wirelessly transmits a state and a linear data of a train signal device to the USN node. The USN node transmits the data received from the sensor node to the reader system. The reader system extracts meaningful situation information from the data received from the USN node. The web server provides the state or the linear data of the train signal device of the reader system to a web. The web server transmits a SMS(Short Message Service) character to a portable terminal(6) of a manager through a CDMA(Code Division Multiple Access) network in case of trouble or emergency state of the train signal device. |
