As the improvement of the technical solution, the t is 30.
As the improvement of the technical solution, further include：When system detectio is to breaking down, then automatic shutdown.
Further, the failure includes that projecting apparatus exception and/or fan appearance exception occurs.
The system detectio can automatically adjust fan gear to environment temperature, brightness etc.；Such as：
The mainboard of Systems Projection instrument is equipped with temperature sensor, is more than threshold value, system control when detecting that mainboard temperature is excessively high
Fan processed improves gear automatically, and wind speed improves；Also is provided with temperature sensor at projecting apparatus shaven head, when system detectio at ray machine lamp
Temperature increase, then control rotation speed of the fan raising；
System is additionally provided with brightness detection and brightness regulation, such as high, medium and low third gear brightness, and system detectio to environment is daytime,
Then automatic regulating lightness low spot then lightens a little at night, correspondingly, the wind speed of fan changes with one, wind-speed gear is according to electricity
Size wind speed setting is flowed, system first passes through software set difference size of current in advance, and such as when remote controler selects a gear, LED drives
Dynamic circuit drives corresponding current, wind speed is corresponded to according to different currents match；According to gear difference, fan Auto-matching is accordingly fast
Degree.
The system is additionally provided with protection module：RD signals stalling protection, i.e., as projecting apparatus is fallen on the ground or line, mainboard are broken
Deng system cannot detect electric fan signal, then prompt goes wrong or abnormal, then system controls projecting apparatus automatic shutdown.It can
To be low and high level detection etc., prompt to go wrong if detecting high level, and then control projecting apparatus forced shutdown.
And when system detectio is excessively high or brightness is very high to projector temperature, when system detectio to brightness is more than preset value
