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 the value of ambient light sensor, otherwise EP (end of program) are read if opening；Next read loop is judged
Whether the value of border optical sensor is within the scope of automatic brightness adjustment, if within the scope of automatic brightness adjustment, DLP outputs are bright
Degree regulation, then program return continue to read the value of ambient light sensor；Otherwise display reminding information, then program, which returns, continues
Read the value of ambient light sensor.
Carry out exploring laser light TV using an ambient light sensor in the DLP output brightness automatic adjusument units of the system
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 is communicated by I2C buses and EM30713 modules, by AML7366SOC intelligent television masters
Control unit actively to initiate to read instruction, read the ambient light LUX numerical value that EM30713 modules detect, pass through LUX values and DLP
Brightness comparison table dynamic regulation DLP display brightness, LUX values and display brightness direct proportionality are exported, when LUX detected values exceed
During DLP brightness mapping ranges, system provides prompt message, instructs the user rationally to set viewing environment to reach optimum visual effect
Fruit.The automatic regulation function can be configured to open or close, and can manually adjust DLP when being set to off closed state shows
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：Whether first determine whether automatic dazzling-proof mesh function
Open, first IR people locator's probe value, otherwise EP (end of program) are read if opening；Next it is according to detected value judgement
No to detect that human body is movable around projection lens, if detecting, human body is movable around projection lens, and DLP is exported into brightness
Adjust to 10 ﹪ of maximum brightness, then program, which returns, continues to read first IR people locator's probe value, if being not detected by
Human body activity around projection lens then sets brightness with user and shown, then program, which returns, continues to read the spy of the first infrared human body
Survey device probe value.
In the automatic anti-glare unit of the system whether projection lens front is detected using an infrared human body sensor
There is human body to block, the present invention uses HC-SR501 infrared human body detecting modules, is powered using 12V DC, output high level 3.3V
Representative detects physical activity, and low level 0V is represented in investigative range without physical activity, and investigative range is 100 cone angles, farthest sense
Should be apart from adjustable for 3 to 7 meters.The module infrared probe is fixedly mounted on immediately ahead of projection lens at 0.5CM, output pin connection
To AML7366SOC intelligent television main control unit GPIOY_1 pins.AML7366SOC intelligent televisions main control unit passes through interval 200
The low and high level that the pin is read in millisecond circulation sets the output brightness of ultrashort focal length rear-projection DLP laser projection display units,
When detecting physical activity, by the 10% of luminance-reduction to high-high brightness, prevent human eye direct-view from causing dazzling phenomenon, work as human body
It is automatic to recover to user's setting brightness to be shown when leaving the region.
As shown in figure 8, the program that actively saves of the system has following steps：First determine 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) are read if opening；Connect down
To judge whether to detect human body activity in viewing areas, if detecting, human body is movable in viewing areas, and DLP is normally defeated
Go out video, be then back to program and continue to read the second IR people locator and the 3rd IR people locator's probe value；If not
Detect that human body then judges whether to be delayed 30 seconds in viewing areas activity, DLP outputs, Ran Houcheng are closed if being delayed 30 seconds
Sequence continues to read the second IR people locator and the 3rd IR people locator's probe value；The journey after being delayed 30 seconds if not being delayed
Sequence returns, and continues to read the second IR people locator and the 3rd IR people locator's probe value.
Detected in the active power saving unit of the system using two HC-SR501 infrared human bodies detecting modules in the stipulated time
Whether there is physical activity in laser television viewing areas, so as to control whether ray machine closes, two HC-SR501 connect respectively
To AML7366SOC main control unit GPIOZ_13 pins and GPIOA_11 pins.It is separately mounted to immediately below front panel both ends with before
The horizontal center line crossover location of casing so that investigative range maximizes.When detect have physical activity in viewing areas when system it is normal
Work, physical activity is not detected in viewing areas in user's setting time, then close DLP laser display units, such a 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 the information of abnormal monitoring port, otherwise EP (end of program) are read if opening；Next the different of reading is judged
Whether normal monitoring information is without exception, if then DLP is normally exported, then program returns to the letter for continuing to read abnormal monitoring port
Breath, show 30 seconds prompt messages if having exception and wait user to operate；User is next determined whether without operation, if then closing
DLP outputs, EP (end of program) are closed, if user has operation, program returns to the information for continuing to read abnormal monitoring port.
The DLP abnormal monitorings information process unit of the system is used to respond ultrashort focal length rear-projection DLP laser projections display list
The abnormality alarming of member.Fan in the GPIOA_12 pins connection DLP system of AML7366SOC chips in DMD driving plates is supervised extremely
Port is surveyed, the GPIOA_13 pins of AML7366SOC chips connect the temperature anomaly monitoring side in DLP system in DMD driving plates
Mouthful, high level represents unusual condition.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, ejection prompt message prompting user processing, user in 30 seconds it is untreated then
Automatically whole laser TV system is closed, avoids the generation of security incident.
