Modularized construction method of centralized control room

The invention discloses a modularized construction method of a centralized control room. The construction method comprises the following steps: at the segment stage, the processes, from structure manufacturing to advanced outfitting of iron fittings, electrical fittings, pipe fittings and air pipes, of the centralized control room are completed, to build a centralized control room module assembly; the centralized control room module assembly is a closed hexahedron structure, and comprises an upper unit and a lower unit, the upper unit and the lower unit each have a top and a bottom, the upper unit is also provided with a cavity, a top opening communicating with the cavity is formed in the top of the upper unit, the bottom of the upper unit presses against the top of the lower unit, an accommodation cavity is defined between the cavity in the upper unit and the top of the lower unit, and the bottom of the lower unit is used for pressing against the deck of a ship; and structure manufacturing of the centralized
