The invention discloses a stage transmission control system. The stage transmission control system comprises a local cluster control unit, a direct memory access unit, a plurality of transit storage units, a data type identification unit, an IP address matching unit, a stage equipment data extraction unit, a stage personnel data extraction unit, a stage field data extraction unit and a data size detection unit. Through adoption of the stage transmission control system, relevant information of a plurality of pieces of equipment and personnel on a stage can be acquired and transmitted dynamically in real time; the accuracy of stage control is increased; control of data flow is realized; the stage potential safety hazard is lowered; and the stage presentation effect is improved.
