The invention relates to a dredge pump serialization control method for trailing suction hopper dredgers during loading processes. The control method includes six control processes of navigation (B1),mud digging (B2), bypass (B3), pump stopping (B4), cabin extraction (B5) and ballasting (B6). Users can conveniently activate various complex control process sequences through an intelligent controlterminal on the table top of a dredging platform, and do not need to adopt traditional control modes to perform single step control; the control method is organically integrated in a conventional dredging monitoring system, so that combined operation can be realized, routine control can be conveniently switched, and intelligent control experience with higher degrees can be provided for the users;the control method is an automatic control system specially designed for realizing functions; and therefore, the automatic controlling on the navigation, mud digging, bypass, pump stopping, cabin extraction and ballasting operation can be realized, and the operation of a dredge pump can be simplified.
