Wherein, light source 101 includes laser instrument and colour wheel, because the restriction of pure color laser application, current LASER Light Source is monochromatic laser light source or two-color laser light source, i.e. by sending the laser instrument of one or both colors, and the fluorescence composition light source that wavelength convert produces, colour wheel includes fluorescent wheel, or fluorescent wheel and filter wheel, fluorescent wheel excites the fluorescence produced with material for transformation of wave length corresponding color, and the laser composition RGB three primary colours sent with laser instrument by Stimulated Light.Owing to wavelength of fluorescence conversion needs the laser facula of high energy to be irradiated to the surface of fluorescent wheel, and the prolonged exposure of high-energy light beam guiding can make fluorescent wheel local produce substantial amounts of heat, even burn, therefore, fluorescent wheel is Periodic Rotating, so laser high-energy light beam guiding forms a circular path on fluorescent wheel, and the distributing of the fluorescent wheel rotated beneficially heat.
Filter wheel is arranged in the emitting light path of fluorescent wheel, and main purpose is that therefore, filter wheel and fluorescent wheel are synchronous rotaries in order to filter the fluorescence being excited to produce, improve color purity.
Ray machine 102 includes the core parts that DLP projects, dmd chip, is made up of thousands of small reflecting mirror, receives the three primary colours light that light source provides according to sequential, receive the modulation of picture signal, light beam being reflected in camera lens 103 by tiny mirror of image content information will be carried.
The size of DMD is the least, both the light beam having required light source outgoing keeps the output of timing, keep the uniformity of beam brightness again simultaneously, prevent the brightness discordance of screen picture, and along with the brightness Decay Rate in time of the light beam from light source outgoing, the beam brightness received in DMD light path also can change.

On the basis of describing laser projection device structure composition, the embodiment of the present invention will combine the start operational process schematic diagram of Fig. 2-1, and an example of laser projection device progress control method is described.
This flow process can be combined the hardware of laser projection device by software and realize, and this flow process comprises the steps:
Step 201: obtain the operational factor in laser projection device running.
Step 202: the operational factor got is contrasted with the parameter preset, it is judged that whether laser projection device breaks down；Wherein, the parameter preset is the parameter under laser projection device normal operating conditions.
Step 203: if being judged as breaking down, then according to comparing result, determine the fault message of laser projection device.
Specifically, the flow process that the laser projection device that the embodiment of the present invention as shown in Fig. 2-1 provides is run can be to perform immediately after the laser projection device start of application the method, such as, after laser projection device receives remote-controlled start-up signal and starts shooting, the step 201 in the flow process that the laser projection device that the embodiment of the present invention provides is run enters execution immediately.Can also be that periodically the laser projection device to duty runs this step by intervalometer.
In step 201 to the detection part measurement in laser projection device to the acquisition of parameter can be real-time acquisition, or regularly obtain, or after measuring parameter, triggered the concrete conditions such as acquisition by the detection part in laser projection device.Further, the acquisition of the operational factor measured detection part in laser projection device can also arrange the priority orders of acquisition according to the concrete condition of the parameter for detecting of the detection part in laser projection device.
Following one or more can be included by the operational factor in the laser projection device that gets in step 201:

Wherein, above-mentioned multiple operational factor has different priority detection ordering; such as, colour wheel rotating speed, Laser Drive stream, rotation speed of the fan, temperature, the priority detection ordering of brightness operational factor are above the detection ordering of placing attitude operational factor of ambient humidity, laser projection device cleanliness factor, protective cover state, laser equipment setting regions human motion state, laser projection device.Or colour wheel rotating speed, Laser Drive stream, rotation speed of the fan, temperature, the detection ordering of brightness operational factor are better than the detection ordering of laser equipment setting regions human motion state; and; the detection ordering of laser equipment setting regions human motion state is better than the ambient humidity at laser projection device place, the detection ordering of laser projection device cleanliness factor; and protective cover state, the detection ordering of the placing attitude operational factor of laser projection device is minimum.
Different priorities detection ordering refers to, preferentially judge the operational factor that priority detection ordering is higher, it is thus possible to know the duty of parts corresponding to this operational factor, generally the detection ordering of the operational factor of some critical components is set to priority-level higher, such as, laser instrument, the basic element of character that the parts such as colour wheel, fan run as safeguards system, preferentially judge that the operational factor that these parts are corresponding is the most normal.
Compared to traditional projector equipment, laser projection device employs fluorescent wheel and two colour wheels of filter wheel, wherein fluorescent wheel is as wavelength convert parts, for coordinating laser jointly to produce the three primary colours needed for light source, if fluorescent wheel can not run well, then static wheel surface got to by laser instrument, will calcination colour wheel, such as moment punctures, and causes irreversible loss.And if filter wheel can not run well jointly with fluorescent wheel, then cannot produce the three primary colours of timing, then ray machine signal processing system cannot be coordinated normally to produce colour picture.Therefore, it is to ensure that light source can be normally carried out wavelength convert that colour wheel runs well, and exports the critical component of complete three primary colours.Colour wheel rotating speed obtains typically by infrared sensor.It will be seen that colour wheel rotating speed is to weigh one of laser projection device highly important parameter whether being in normal operating conditions.

In some embodiments of the invention, the ambient humidity obtained by humidity sensor measurement can also be obtained in step 201.Wherein, owing to the ambient humidity at laser projection device place can affect the heat radiation of laser projection device, humidity sensor can be arranged on the air inlet etc. of laser projection device.
In some embodiments of the invention, the placing attitude of the laser projection device obtained by gravity sensor measurement can also be obtained in step 201.Wherein, owing to different placing attitude can affect the formation of laser projection device heat dissipation wind channel, between heat dissipation wind channel and external environment, the velocity of liquid assets of air there is also difference, for laser projection device, in the case of just throwing (or front throwing) placing attitude, radiating effect generally to be preferred over radiating effect in the case of anti-throwing placing attitude, gravity sensor can with Laser Measurement projector equipment on each change in coordinate axis direction in space by gravitational conditions, it is thus possible to obtain reflecting some initial datas of laser projection device placing attitude, such that it is able to quantify to obtain the placing attitude of laser projection device according to quantizing rule set in advance.
In some embodiments of the invention, the rotation speed of the fan obtained by rotation speed of the fan detection part measurement can also be obtained in step 201.Wherein, laser projection device is usually provided with multiple fan, one or more fan can be provided with at such as air inlet or air outlet, seal light source enclosure interior also can be provided with one or more fan to increase airflow speed, at power panel, board, the radiator etc. such as plate parts side is driven typically to be also equipped with fan, fan in laser projection device is usually DC fan, rotation speed of the fan detection part can be fan circuit part in for feeding back the circuit part of rotation speed of the fan, such as feedback pin.
In some embodiments of the invention, other measures the parameter that parts measurement is arrived can also to obtain some in step 201.Such as; if laser projection device is provided with projection lens protective cover; then need to detect whether normally to open protective cover when start; otherwise will be unable to normal projection; protective cover detection part can measure protective cover state; in running status, regularly detect whether protective cover occurs abnormal closedown, such as manual-lock；The most such as, laser projection device current environment clean level will affect equipment and can normally enable and the operation working time of equipment, defecator detection part can be with Laser Measurement projector equipment cleanliness factor, and use infrared sensor or Hall element to obtain laser equipment setting regions human motion state, such as in the view field of regulation, laser beam brightness is the highest, should prevent human body or animal from entering this region, in order to avoid human body or animal body are damaged by high-energy light beam guiding.
Should be understood that, measurement parts in laser projection device can include multiple sensors and feedback circuit etc., in order to collect the operation information of laser projection device internal components and machine system, listing the parameter that the detection part measurement in some laser projection device is arrived in the application, the parameter that the detection part in laser projection device is measured is not limited in the application cited part.
The parameter arrived based on the detection part measurement in laser projection device accessed in step 201, can contrast the parameter got with the parameter preset in step 202., judge whether laser projection device breaks down；Wherein, the parameter preset is the parameter under laser projection device normal operating conditions.Further, the parameter preset can be default parameter value or span, specifically can preset according to different parameter situations.
Such as, within a period of time of laser projection device normal boot-strap, in such as N time second (N is the integer more than or equal to 1), colour wheel should be able to reach a certain rotating speed set in advance or the range of speeds under the drive of motor, if the colour wheel rotating speed got is not reaching to the rotating speed (being such as preset with rotating speed value or rotating speed span) preset, or difference is relatively big (being such as preset with the threshold value of difference) compared with default rotating speed, then may determine that colour wheel is in improper duty, laser projection device can not normally enable in this case.
The most such as; during laser projection device is run; if the temperature sensor measurement got to the value of temperature parameter exceeded value or the span of predetermined temperature parameter; assume that the temperature measuring the temperature parameter display present laser projector equipment arrived is too high, in this case in order to protect laser projection device should stop the operation of projection device system.
If judging that laser projection device breaks down in above-mentioned steps 202, the comparing result according to step 202 described in step 203 can be performed the most further, determine the fault message of laser projection device.
Wherein, fault message can be specifically failure code.Similar with most equipment, in advance different types of equipment fault can be provided with corresponding failure code in laser projection device to represent, the numbering that failure code can be made up of numeral, the form of such as XX or XXXX etc. (X represents digit symbol), it is stored in advance in laser projection device, specifically can inquire about this form according to the comparing result of step 202 just may determine that the failure code of laser projection device to be stored as the form of form.
