description The invention discloses a control river reach ship water supply and drainage judgment method based on a grid reference course, and belongs to the field of intelligent shipping and ship navigation application. The method comprises the following steps: on the basis of a calculation range of a control river reach and coordinates of a channel mileage line, gridding the control river reach and establishing an index by combining the actual condition of the control river reach and the advantages of a two-dimensional array, and calculating the position of a grid distance close to the channel mileage line by taking a grid center point as a coordinate; and then calculating the reference course of each grid by using the reference course of the channel mileage line. Through the method, the longitude and latitude of the ship AIS in the control river reach are subjected to coordinate change to obtain the grid index, the grid reference course is used for ship water supply and drainage judgment, a command system is provided
