The invention discloses a ship navigation state monitoring and alarming system comprising modules such as a direction finder for determining the real-time direction information of a ship by signal communicating with a beacon station on the shore base; an anemometer for detecting wind speed information of the sea surface during the navigation of the ship; and a water temperature observer for detecting temperature information of seawater under different water depths, wherein the system further comprises an analysis module for receiving data information transmitted by the direction finder, the anemometer, the water temperature observer, the barometer, the Beidou positioning module and the angle acquisition module; the analysis module is provided with a roll angle threshold and a standard parameter in a safe navigation state of the ship; and the data analysis module compares the received data information with the internally stored standard parameters to determine whether the ship is sailing in a safe state, feeds back the state parameters under safe navigation to the shore-based command center if so, otherwise sends an alarm signal, and transmits the alarm signal to the shore-based command center.
