Embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with attached
Figure and specific embodiment are described in detail.
Referring to Fig. 1, Fig. 1 is a kind of flow of projecting apparatus trouble free service method provided in an embodiment of the present invention
Schematic diagram, as shown in figure 1, comprising the following steps：
S101, the detection projecting apparatus fan rotation speed of the fan.
When projecting apparatus works, ray machine, processor, internal battery discharge and recharge can produce substantial amounts of heat, then add
Upper projecting apparatus inner space is narrow and small, if not in time distributed heat, will be unable to ensure the peace of projecting apparatus
Full work.For example, internal battery can produce a large amount of gases because of hot environment, drum can be induced to polymer battery
Bag, blast even can be induced to lithium electricity.
Wherein, the fan thermal component important as projecting apparatus, the detection to rotation speed of the fan are particularly important.
Rotation speed of the fan is bigger, and radiating effect is better, and rotation speed of the fan is smaller, and radiating effect is poorer.Due to projecting apparatus
Ray machine is the core luminous component of projecting apparatus, and the part that power consumption is maximum, therefore, rotation speed of the fan often root
It is adjusted according to the ray machine temperature of ray machine.Generally, ray machine temperature can be at 2~3 minutes after ray machine is opened
Inside reach higher temperature, therefore, in normal operation, rotation speed of the fan should maintain maximum (top) speed.
It can be seen that the rotation speed of the fan of the fan of the projecting apparatus is detected for ensureing that projecting apparatus trouble free service has weight
The meaning wanted.
S102, the detection projecting apparatus internal battery battery temperature.
Wherein, for micro projector, for the portable consideration of user, it will usually placed inside it big
The internal battery of capacity, in order to ensure the projecting apparatus normal projection of two to three hours, internal battery capacity are general
In more than 5000mAh, some is even in more than 10000mAh.Internal battery in discharge and recharge, itself
Also substantial amounts of heat energy can be produced, along with heat energy caused by the foregoing ray machine or processor referred to so that built-in
The battery temperature of battery is likely to exceed safe temperature value, very big potential safety hazard be present.
It can be seen that the battery temperature of the internal battery of the projecting apparatus is detected for ensureing projecting apparatus trouble free service tool
There is important meaning.
Wherein, the battery temperature of internal battery can pass through cell panel NTC (Negative Temperature
Coefficient, negative temperature coefficient) sensor detection, the sensing of internal battery casing peripheral can also be passed through
Device detects, and in general, has 3-4 degree compared to the environment temperature of casing peripheral by the temperature of NTC detections
Difference when 59 degree of battery container temperature (i.e., battery NTC detection temperatures are 55 degree), was detected specifically
Cheng Zhong, temperature difference can be taken into account.
S103, the detection projecting apparatus ray machine ray machine brightness.
As it was previously stated, ray machine is the core luminous component of projection, for projecting apparatus Ordinary Light Sources Have, no matter
It is LED light source or LASER Light Source, its power consumption has all reached tens watts of rank, heat caused by ray machine
More than half of whole projecting apparatus generation heat energy can be occupied.Existing projecting apparatus, it can be all attached with light source
Temperature detection sensor, real-time delivery light-source temperature to device core processor.
Wherein, heat energy caused by ray machine is directly proportional to ray machine brightness, and ray machine brightness is higher, heat caused by it
Can be necessarily more, ray machine brightness is weaker, and its caused heat energy also can be reduced accordingly.
It can be seen that the ray machine brightness of the ray machine of the projecting apparatus is detected for ensureing that projecting apparatus trouble free service has weight
The meaning wanted.
S104, be less than default first tachometer value when the rotation speed of the fan, and the rotation speed of the fan be more than or
Equal to default second tachometer value, and the ray machine brightness is default first brightness value, and the ray machine is bright
Degree is from first luminance-value reduction to default second brightness value.
Wherein, when being classified to rotation speed of the fan value, can be classified using the rotating speed of fan, can also
It is classified using the dutycycle of fan, because the dutycycle of fan is typically more stable differentiation rotating speed gear
The factor, therefore in the present embodiment, we weigh default tachometer value using dutycycle.
Wherein, default first tachometer value corresponds to the maximum (top) speed of fan, can be according to the configuration of fan in itself
And radiating requirements are set, such as 95% dutycycle either 96% dutycycle or 98% dutycycle etc.；
Default second tachometer value can set such as 80% dutycycle either 85% dutycycle or 88% dutycycle
Etc.；Other rotation speed of the fan values, such as the 3rd tachometer value can also be set up, default 3rd tachometer value can
To set such as 55% dutycycle either 60% dutycycle or 62% dutycycle etc..On the other hand, this implementation
Example is not construed as limiting.
Wherein, the brightness value of ray machine brightness can be pre-set according to the luminous flux of ray machine, and the light of ray machine leads to
Amount is higher, and power consumption is higher, and caused heat energy will be higher.Ray machine brightness can be according to the configuration of ray machine in itself
To set, the high-high brightness of ray machine can be preset as the first brightness value, time big brightness of ray machine is preset as
Second brightness value, other ray machine brightness values can also be set up.From the point of view of visual effect, the first brightness value can be managed
Solve to be completely bright, the second brightness value can be understood as half bright, can also set the 3rd brightness value, the 3rd brightness value
It can be understood as glimmer.From the point of view of luminous flux, so that ray machine highlight flux is 200 lumens as an example, Ke Yishe
It is 200 lumens either 195 lumens or 190 lumens etc. to put the first brightness value, can set the second brightness
It is worth for 100 lumens either 95 lumens or 90 lumens etc., it is 50 lumens that can set the 3rd brightness value
Either 45 lumens or 40 lumens etc..On the other hand, the present embodiment is not construed as limiting.
As it was previously stated, after ray machine is opened, ray machine temperature can reach higher temperature in 2~3 minutes, therefore,
Under normal operation, rotation speed of the fan should be maximum tachometer value, i.e. rotation speed of the fan should be greater than or be equal to
Above-mentioned default first tachometer value.If rotation speed of the fan is less than default first tachometer value, mean to project
The radiating of instrument is unable to reach Expected Results, and for security consideration, projecting apparatus should take appropriate measures to ensure
Projecting apparatus trouble free service.
In the present embodiment, rotation speed of the fan is less than default first tachometer value, and more than or equal to default the
Two tachometer values, although being not reaching to the first tachometer value, perhaps already close to the first tachometer value, it is impossible to complete
It is complete to judge that fan has problem, therefore in the case, in order to not reduce the experience of user, can take by
The measure of ray machine luminance-reduction reduces the temperature of ray machine, projecting apparatus is maintained safe work state.If
Ray machine brightness is the first brightness value, in order to avoid projecting apparatus overheats, can be taken ray machine brightness from described the
One luminance-value reduction to the second brightness value.
S105, be less than default first temperature value when the battery temperature, and the battery temperature be higher than or
Equal to default second temperature value, and the ray machine brightness is default first brightness value, and the ray machine is bright
Degree is from first luminance-value reduction to default second brightness value.
Wherein, in order to ensure projecting apparatus trouble free service, it is necessary to carry out differentiated control, root to battery temperature in advance
Different actions is responded according to different temperature levels, so as to realize projecting apparatus trouble free service.Currently, in-built electrical
Pond can be divided into following several discharge and recharge sections according to own temperature value：0 degree~45 degree are normal temperature charging zone,
In normal temperature charging zone, battery can be with the full current charge-discharge electricity of full voltage；45 degree~60 degree are high-temperature charging area, in height
Warm charging zone battery need to be depressured drop current charge；More than 60 degree are to forbid charging zone.High-temperature charging can be selected
Some of a relatively high temperature value is as default first temperature value in area, such as 54 degree either 55 degree or
56 degree etc.；Some temperature value relatively low in high-temperature charging area can be selected as the default second temperature
Angle value, such as 45 degree either 46 degree or 47 degree；Other battery temperature values can also be set up.It is right
This, the present embodiment is not construed as limiting.
In the present embodiment, it is less than default first temperature value in battery temperature, greater than default
Two temperature values, if ray machine brightness is default first brightness value, now, if ray machine works long hours full
Bright state, it will make temperature inside projecting apparatus maintain the high-temperature charging area of battery for a long time, or even have can
It can rise to temperature and forbid charging zone, larger risk is brought to internal battery, in order to avoid projecting apparatus mistake
Heat, it can take ray machine brightness from first luminance-value reduction to the second brightness value.
It should be noted that in the present embodiment, sequential is not present successively in these three steps of S101 to S103,
S101 can be first carried out, S102 can also be first carried out, S103 can also be first carried out, can also be performed simultaneously
Equally sequential is also not present successively in person's any two or three steps, the two steps of S104 to S105.
In the present embodiment, the rotation speed of the fan of fan during by working projecting apparatus, the battery temperature of internal battery
The ray machine brightness of degree and ray machine carries out joint-detection, and forms " set boxing ", is advantageous to make inside projecting apparatus
Temperature maintains long-term level of security.
Optionally, the battery temperature of the internal battery of the detection projecting apparatus, including：At interval of the unit interval
Temperature detection is carried out to the internal battery of projecting apparatus, n times are continuously detected, by the detection of the n times
As a result battery temperature of the average value as the internal battery, the n times are the positive integer pre-set.
Optionally, the rotation speed of the fan of the fan of the detection projecting apparatus, including：At interval of the unit interval to throwing
The fan of shadow instrument carries out a Rotating speed measring, continuously detects n times, by the flat of the testing result of the n times
Rotation speed of the fan of the average as the fan, the n times are the positive integer pre-set.
Wherein, at interval of the unit interval, such as 3 seconds be could be arranged to either 5 seconds or 6 seconds etc., even
Continuous detection n times, could be arranged to such as 30 times either 36 times or 40 times or 80 times or 100
It is secondary or 120 times etc., on the other hand, present embodiment is not construed as limiting.
Due to projecting apparatus in the course of the work, its internal battery temperature and rotation speed of the fan are in moment fluctuation
State, the only numerical value with one-time detection, can not reflect real working environment, therefore, in present embodiment,
By carrying out the detection of continuous several times to temperature, avoid projecting apparatus and make inappropriate response.
In the embodiment of the present invention, the above method can apply in projecting apparatus or micro projector equipment, i.e.,
These equipment can realize the above method.

Ray machine.
Wherein, when rotation speed of the fan is less than the second tachometer value, and is more than or equal to three tachometer values, such as light
Machine brightness is the second brightness value, now, although rotation speed of the fan is also not below minimum speed, wind now
It (is probably due to the electrical event of the mechanical breakdown either fan of fan that fan, which has been in abnormal operation,
Barrier), the heat-sinking capability of fan can not meet that ray machine works long hours in half bright state, in order to avoid projecting apparatus
