System for monitering state of marine construction

A system for monitoring state of marine construction is provided to improve the wireless telecommunication in the long distance or obstacle by forming the transit network through the wireless communications unit. The lighthouse state detection part(100) senses the state of the lighthouse formed in the oceanic facility like the light beacon and drifting. The collision sensor(200) measures the collision state between the oceanic facility like the light beacon and drifting and ship, acceleration data according to collision and inclination data. The power detector(320) senses the normal input state of the input power source by measuring the voltage of the power supplied in the power supply unit. The wireless communications unit(400) wirelessly transmits data sensed in the lighthouse state detection part, the collision sensor and power detector in the remote site. The controller(500) collects data measured in the lighthouse state detection part, the collision sensor and power detector. The remote server part(600) sends the warning tone and light to administrator by analyzing measured data through the wireless communications unit.
