Abstract: PURPOSE: A monitor system which uses a mobile network, a master sensor node and a server device are provided to perform real time monitoring with minimum manpower by autonomously recognizing event generation between the master sensor node and a server. CONSTITUTION: A sensor(100) transmits event information to a sensor node(200) through a wireless channel. A sensor node is connected to the sensor through a wire channel. The sensor comprises a padding sensor buried under the road or underground. The sensor node obtains image information an event generation source and/or azimuth showing the direction of the event generation source. A master sensor node(300) is connected to the sensor node through the wireless channel.
