The invention relates to the field of intelligent shipping and ship draught real-time detection, in particular to a ship draught real-time detection method and system based on RTK carrier phase difference. The method comprises the steps that an RTK base station is arranged at the top or forecastle of a ship, and satellite data are observed and received through the RTK base station; an RTK mobile station is arranged on the water surface, and satellite data are observed and received through the RTK mobile station; calculating coordinates of the RTK base station and the RTK mobile station by using satellite data received by the RTK base station and the RTK mobile station; and calculating the draft of the ship by using the coordinates of the RTK base station and the RTK mobile station. The system comprises an RTK base station, an RTK mobile station, a data processing device and a data transmission device. According to the invention, the RTK mobile station is matched with the RTK base station installed at the top of the ship to dynamically detect the ship draft in real time, so that the ship navigation safety is guaranteed.
