1. 2D and 3D automatic switching control equipment that is used for 3D equipment, it is characterized in that, comprising:

  • the drive circuit of power supply, signal acquisition circuit, CPU, power generation unit, power generation unit, power transmission unit, primary importance inductor, can modulate the optical modulator of projection ray and drive the Modulator Driver IC for Lightwave Communication Systems of described optical modulator work;

    Described power supply is connected with the drive circuit of described CPU, described power generation unit, is used for the drive circuitry to described CPU and described power generation unit;

    Described signal acquisition circuit is connected with described CPU, for the broadcast state signal of acquired projections machine and to described CPU output signal;

    Described CPU is connected with the drive circuit of described power generation unit, is 2D or 3D picture for what judge the current broadcast of projector according to the broadcast state signal that receives, and assigns corresponding instruction to the drive circuit of described power generation unit;

    The drive circuit of described power generation unit is connected with described power generation unit, for generation of the driving signal, and is transferred to described power generation unit driving a signal;

    Described power generation unit is connected with described power transmission unit, for generation of power, and move to projector lens by the described optical modulator of described power transmission unit drive when the current broadcast 2D of projector picture before, drive described optical modulator by described power transmission unit and shift out before projector lens when the current broadcast 3D of projector picture;

    One end of described primary importance inductor is connected with described CPU, is used for detecting that described optical modulator moves to projector lens the place ahead or when shifting out from projector lens the place ahead, testing result is fed back to described CPU.
