Coding object quantity communication method and device

The invention provides a coding object quantity communication method and device. The method comprises the following steps: receiving a coding data signal sent by an upper computer, wherein the data signal comprises an encoding catalogue, the encoding catalogue comprises at least one encoding catalogue datum, the encoding catalogue datum corresponds to the code printing code, and the code printingcode comprises at least one code printing code datum; after the printing tasks of all the coding data in the coding codes are completed, marking the task information of the coding codes as a completion state, wherein the task information comprises the name of the code printing code and the number of the code printing code data; and sending the task information to the upper computer. The coding catalogue and the coding data sent by the upper computer are automatically received through the field control system, information feedback is conducted, automatic communication of coding information canbe achieved, practicabilit
