The invention discloses an intelligent modular metering system which includes a storage device, first storage containers, second storage containers, a conveying device, first metering units, second metering units, a first transporting unit, a second transporting unit and receiving containers. Thus, a control unit is used for instructing and controlling the conveying device and the first transporting unit to move the first storage containers or the second storage containers to the receiving containers, where the matched first metering units or second metering units are placed, for blanking and weighing, and then instructing and controlling the second conveying unit to move the receiving containers to preset positions for blanking to finish a formula, so that raw materials of different forms and raw materials of the same formula can be combined and formulated in the same system, a great number of raw materials of various types and different forms can be contained in a limited space, and the intelligent modular metering system is diversified in metering control for selection and modularized for unlimited extension of components, has an Internet of Things architecture and is capable of remote control.
