The invention discloses a stage element centralized control system. The stage element centralized control system comprises a server and a display control terminal, wherein the server is connected with the display control terminal, the server is connected with a wireless control terminal through a wireless router, a large screen host computer is connected with the wireless router, an inertial motion capture system and an LED (light emitting diode) large screen, and the server is further connected with a DMX512 (digital multiplex 512) control platform, a PLC (programmable logic controller) centralized control system and a 232T0485 serial port. The stage element centralized control system integrates stage elements into a software control system, not only achieves control presetting and automatic execution in a time series for the stage elements, but also can switch to real time field control as needed whenever necessary, guarantees perfect and reasonable presentation of the stage elements in a performance process, intelligently and accurately controls video, voice frequency, lamplight, machinery, scenes and the like in a stage performance, and prevents faults or faulty operation from occurring. Additionally, the stage element centralized control system is convenient to carry and simple to use, and effectively reduces cost of the stage performance.
