The utility model discloses a naval vessel sound automatic control device. It includes control system and message transmission system, message transmission system is through the data fusion systems and control headtotail, last visibility sensor and the naval vessel dynamic sensor of being connected with of message transmission system, the data fusion system has the ship type database that the storage has ship type information, control system still is connected with a sound database, the visibility sensor, boats and ships dynamic sensor, the data message of ship type database can be through sending to control system after message transmission system and the processing of data fusion system. Its advantage lies in: can be through gathering visibility at that time, boats and ships dynamic scheduling information in real time to combine naval vessel ship type data storehouse, integrated treatment, decision -making realize naval vessel sound signal lamp airing of views automaticity, ageing, rapidity, accuracy, have overcome a great deal of unfavorable of artifical airing of views, and the security that has improved the naval vessel and all can use, has stronger practicality under various weather conditions.
