The extended power-on time required for different projection devices may vary, for example, 1 minute for projector 401, and when power is tapped to projector 401 at 10 o 'clock 30, projector 401 will be in operation at 10 o' clock 31.
To enhance the control system of the projection device, the system will set different turn-on sequences based on the turn-on extension times of different projection devices. The concrete measures are as follows: the starting mode also comprises a starting sequence and a starting delay time of the projection equipment;
and the control panel controls the corresponding projection equipment to start up according to the starting-up sequence and the starting-up delay time length.
