As shown in fig. 6, the DLP outputs brightness Automatic adjusument program of the system has following steps：First determine whether brightness certainly
Whether dynamic regulatory function is opened, and reads the value of ambient light sensor, otherwise EP (end of program) if opening；Next judge read loop
Whether, within the scope of automatic brightness adjustment, if within the scope of automatic brightness adjustment, DLP outputs are bright for the value of border optical sensor
Degree is adjusted, and then program returns the value for continuing to read ambient light sensor；Otherwise display reminding information, then program return and continue
Read the value of ambient light sensor.
Used in the DLP output brightness Automatic adjusument units of the system, an ambient light sensor carrys out exploring laser light TV
Ambient light in use environment is strong and weak, and the ambient light sensor in this unit selects EM30713 modules, the module spectral response
Wide coverage and can eliminate 50HZ/60HZ external light sources interference, maximum environment optical detection value is up to 2000LUX.
AML7366SOC intelligent televisions main control unit passes through I2C buses and EM30713 modules communicate, by AML7366SOC intelligent television masters
Control unit actively initiates to read instruction, reads the ambient light LUX numerical value that EM30713 modules are detected, by LUX values and DLP
Output brightness comparison table dynamic regulation DLP display brightness, LUX values and display brightness direct proportionality, when LUX detected values exceed
During DLP brightness mapping ranges, system provides information, instructs the user rationally to arrange viewing environment to reach optimum visual effect
Really.The automatic regulation function can be configured to and open or close, and can manually adjust DLP when closed state is set to off and show
The brightness of unit.LUX detected values are shown in following form with DLP display brightness mapping tables：
| LUX values | 0-10 | 10-35 | 35-75 | 75-100 | 100-300 | 300-500 | 500-1000 | >1000 |
| Brightness | 50% | 60% | 70% | 80% | 90% | 95% | 100% | Prompting |
As shown in fig. 7, the automatic dazzling-proof mesh program of the system has following steps：Automatic dazzling-proof mesh function is first determined whether whether
Open, first IR people locator's probe value, otherwise EP (end of program) is read if opening；Next according to detected value judgement it is
It is no to detect human body activity around the projection lens, if detecting human body activity around the projection lens, DLP is exported into brightness
Adjust to the 10 of maximum brightness, then program return continues to read first IR people locator's probe value, if being not detected by
Human body is movable around projection lens then to be shown with user's setting brightness, and then program returns and continues to read the spy of the first infrared human body
Survey device probe value.
Used in the automatic anti-glare unit of the system, whether an infrared human body sensor is detecting in front of projection lens
There is human body to block, the present invention uses HC-SR501 infrared human body detecting modules, using 12V direct current supplys, export high level 3.3V
Representative detects physical activity, and low level 0V is represented without physical activity in investigative range, and investigative range is 100 cone angles, farthest to feel
Should be apart from adjustable for 3 to 7 meters.The module infrared probe is fixedly mounted at projection lens dead ahead 0.5CM, output pin connection
To AML7366SOC intelligent television main control unit GPIOY_1 pins.AML7366SOC intelligent televisions main control unit is by interval 200
Millisecond circulation reads the low and high level of the pin arranging the output brightness of ultrashort focal length rear-projection DLP laser projection display units,
When physical activity is detected, by the 10% of luminance-reduction to high-high brightness, prevent human eye direct-view from causing dazzling phenomenon, work as human body
When leaving the region, recover to user's setting brightness automatically to be shown.
As shown in figure 8, the active energy-conservation program of the system has following steps：First determine whether whether active power saving function beats
Open, the second IR people locator and the 3rd IR people locator's probe value, otherwise EP (end of program) is read if opening；Connect down
To judge whether to detect human body activity in the viewing areas, if detecting human body activity in the viewing areas, DLP is normally defeated
Go out video, the program that is then back to continues to read the second IR people locator and the 3rd IR people locator's probe value；If not
Detect human body and then judge whether time delay 30 seconds in viewing areas activity, close DLP outputs, Ran Houcheng if time delay 30 seconds
Sequence continues to read the second IR people locator and the 3rd IR people locator's probe value；The journey after time delay 30 seconds if the non-time delay
Sequence is returned, and continues to read the second IR people locator and the 3rd IR people locator's probe value.
Used in the active power saving unit of the system in two HC-SR501 infrared human bodies detecting module detection stipulated times
Whether physical activity is had in laser television viewing areas, so as to controlling whether ray machine closes, two HC-SR501 connect respectively
To AML7366SOC main control unit GPIOZ_13 pins and GPIOA_11 pins.Be separately mounted to immediately below front panel two ends with it is front
The horizontal center line crossover location of casing so that investigative range is maximized.When detect have physical activity in viewing areas when system it is normal
Physical activity is not detected in viewing areas in work, user's setting time, then close DLP laser display units, this kind of situation
Under, if user returns to viewing areas, automatically open up DLP laser display units and recover normal display.
As shown in figure 9, the DLP abnormal monitoring message handling programs of the system have following steps：First determine whether that DLP is supervised extremely
Whether control function is opened, and reads the information of abnormal monitoring port, otherwise EP (end of program) if opening；Next judge the different of reading
Often whether monitoring information is without exception, if then DLP is normally exported, then program returns the letter for continuing to read abnormal monitoring port
Breath, shows 30 seconds informations if having exception and waits user operation；User is next determined whether without operation, if then closing
DLP outputs, EP (end of program) is closed, if user has operation, program returns the information for continuing to read abnormal monitoring port.
The DLP abnormal monitorings information process unit of the system is used for responding ultrashort focal length rear-projection DLP laser projections display list
The abnormality alarming of unit.Fan in the GPIOA_12 pins connection DLP system of AML7366SOC chips in DMD driving plates is supervised extremely
Survey port, the temperature anomaly monitoring side in the GPIOA_13 pins connection DLP system of AML7366SOC chips in DMD driving plates
Mouthful, high level represents unusual condition generation.AML7366SOC intelligent televisions main control unit reads the two by being spaced circulation in 1 second
The low and high level of pin, if detecting exception, eject information prompting user process, user in 30 seconds it is untreated then
It is automatically switched off whole laser TV system, it is to avoid the generation of security incident.
