When in fog weather, the visibility at sea was extremely poor, which brought great difficulties to the normal navigation of ships. In the history of navigation, there were a large number of accidents related to the collision of ships and the collision of reefs caused by fog. In order to ensure the safety of fog navigation, it is very necessary to have fog horn to be constantly sounded to attract the attention of passing ships.
