The invention discloses a ship situation danger detection method in the inland ship domain. The method comprises the following steps: establishing an inland ship domain model; obtaining an external safety distance boundary formula through the inland ship domain model; establishing a coordinate system relative to a ship body, and obtaining a target ship coordinate TS; the target ship speed is obtained through the target ship coordinate TS, and the relative speed of the ship and the target ship is obtained through the target ship speed; establishing a collision danger detection line expression through the target ship coordinate TS, and determining a collision intersection point coordinate through a collision prediction expression and an external safety distance boundary equation; the meeting time of the collision danger detection line of the target ship and the ship domain safety distance boundary intersection point is obtained through the collision intersection point coordinates and the relative speed; according to the position relation between the collision danger detection line and the safe distance boundary and the encounter time, the inland ship situation danger level is divided, danger collision detection can be carried out in real time, safety is high, and stability is good.
