The invention discloses a constant-speed high-frame-rate projection control circuit and method and an industrial light machine. The circuit comprises a main control module, a DLP control module, a DLP display module, a light source driving module, a first external control module and a second external control module. The main control module comprises a main control unit and a PWM trigger unit. The main control unit is used for receiving a trigger input signal of a first external control module, and the PWM trigger unit is used for generating a PWM pulse signal to trigger the DLP control module; the DLP control module is used for controlling a projection picture according to the PWM pulse signal; the DLP display module and the light source driving module are used for realizing structured light output according to the projection picture; the DLP control module is used for sending a synchronizing signal to the camera for acquisition when the projection picture is controlled; the main control unit is used for gene
