The invention discloses a method, a system and a device for monitoring and pre-warning inland ship stability in real time. The method comprises the following steps: S1, obtaining navigation information of a ship in real time, wherein the navigation information comprises ship both-side waterline change information acquired by a liquid level monitoring system, ship rolling angle information acquired by an inclination angle monitoring system, and wind speed and wind direction information acquired by an wind speed monitoring system; S2, according to the acquired ship both-side waterline change information, calculating a current displacement volume and a current buoyant centre position of the ship; according to the acquired ship rolling angle information, calculating an angular acceleration and an angular speed of ship rolling; and according to the acquired wind speed and wind direction information, calculating a wind heeling moment of the ship; and S3, comparing the calculated data with a standard value, pre-warning a stability condition and hazard level of the ship if a hazardous condition appears, and timely giving out pre-warning. According to the method, the system and the device, the dynamic stability condition of ship navigation can be monitored in real time, and pre-warning for the hazardous condition can be given according to the monitored results.
