Description
Technical field
The present invention relates to photovoltaic technical field of measurement and test, specially a kind of photovoltaic infrared imaging delayed test dress
Put.
Background technology
Takeoff and landing due to aircraft mainly to be completed to the observation of runway by pilot, is therefore running into bad weather
During condition, once pilot is unsighted, will result in aircraft and cannot smoothly take off or land, bring danger.
Equip infrared what comes into a driver's strengthening system for the current proposition of above-mentioned situation aboard, that is, by being arranged on aircraft forward
Infrared viewing camera to pilot provide one tunnel observe video, in order to assisting in flying person in takeoff and landing to runway situation
Observation.But because video image all has certain retardance in transmission, if postpone larger, pilot can be caused
Mistake is observed, therefore according to the requirement of security aspect, the retardance index of photovoltaic infrared imaging about 100 bold and unconstrained seconds,
And required precision reaches Millisecond, meet pilot reaction time requirement.Require for These parameters, still not supporting at present
Test device.
Content of the invention
For solving the problems, such as to lack the device that photovoltaic infrared imaging retardance index is tested in prior art,
The present invention proposes a kind of photovoltaic infrared imaging delayed test device.
The technical scheme is that：
A kind of described photovoltaic infrared imaging delayed test device it is characterised in that：Including target source, light shield, height
Accurate synchronization clock, imaging lag record system and tripod；
Tested photovoltaic is positioned over target source dead ahead, and the picture signal of tested photovoltaic output collection is to imaging
Postpone record system；
Described target source is made up of mid-infrared LED array, is placed in light shield；
High-precise synchronization clock is connected with tested photovoltaic and imaging lag record system respectively；Tested photovoltaic carries
For trigger to high-precise synchronization clock, high-precise synchronization clock log is imaged initial time；Imaging lag record system pair
The picture signal of tested photovoltaic input is processed, and obtains the moment understanding image according to high-precise synchronization clock log；
The interval being calculated as initial time and obtaining between the moment understanding image obtains the delayed imaging time of tested photovoltaic.
Further preferred version, a kind of described photovoltaic infrared imaging delayed test device it is characterised in that：In red
Outer LED array is cold light source device.
Further preferred version, a kind of described photovoltaic infrared imaging delayed test device it is characterised in that：Shading
Cover internal coat has spuious Xanthophyll cycle coating.
Beneficial effect
Advantages of the present invention：Achieve and photovoltaic infrared imaging is postponed to carry out quick, high-acruracy survey.Due to tradition
Infrared target source cannot realize quickly opening and close, especially close when with heat residual, therefore cannot be to photovoltaic
Infrared imaging carries out system-level measurement.Mid-infrared LED array is combined by the present invention with high-precise synchronization clock, has built one
Cover portable photovoltaic infrared imaging delayed test device, under the various environment such as achievable laboratory, outfield, imaging is prolonged
The quick test of index late.
The additional aspect of the present invention and advantage will be set forth in part in the description, and partly will become from the following description
Obtain substantially, or recognized by the practice of the present invention.
Brief description
The above-mentioned and/or additional aspect of the present invention and advantage will become from reference to the description to embodiment for the accompanying drawings below
Substantially and easy to understand, wherein：
Fig. 1 is present configuration composition figure：
In Fig. 1：1st, target source；2nd, light shield；3rd, tripod；4th, high-precise synchronization clock；5th, imaging lag record system.
Specific embodiment
Embodiments of the invention are described below in detail, described embodiment is exemplary it is intended to be used for explaining the present invention, and
It is not considered as limiting the invention.
As shown in figure 1, the invention provides a kind of photovoltaic infrared imaging delayed test device, comprising target source, screening
Light shield, high-precise synchronization clock, imaging lag record system and tripod.
Tested photovoltaic is positioned over target source dead ahead, and tested photovoltaic is connected with imaging lag record system,
The picture signal of tested photovoltaic output collection is to imaging lag record system.
Described target source is made up of mid-infrared LED array, is placed in light shield, and when reducing test, external stray light is to survey
The impact of test result, in order to increase light shield effect further, has spuious Xanthophyll cycle coating in light shield internal coat.
Photovoltaic infrared imaging delayed test refers to that test starts to be integrated to by light-metering from tested photovoltaic detector
Electric output of products understands the time interval till image.So using high-precise synchronization clock respectively with tested photovoltaic and becoming
Connect as postponing record system, when tested photovoltaic detector starts integration, tested photovoltaic provide trigger to
High-precise synchronization clock, high-precise synchronization clock log is imaged initial time；And imaging lag record system is produced to tested photoelectricity
The picture signal of product input is processed, and obtains, also according to high-precise synchronization clock log, the moment understanding image, is calculated as
As initial time with the interval that obtains between the moment understanding image just can obtain the delayed imaging time of tested photovoltaic.
In addition, the mid-infrared LED array that the present invention adopts is cold light source device, there is not heat residual when closed.Due to
Long-time, multicycle duplicate measurements need to be carried out, target source the operation such as completes to open, closes in each cycle domestic demand, such as during test
Fruit adopts ordinary light source, after a period of time has passed caused heat residual, can lead to the test product cannot correct resolution target
Source is in opens or closed mode, therefore needs from cold light source device.
Although embodiments of the invention have been shown and described above it is to be understood that above-described embodiment is example
Property it is impossible to be interpreted as limitation of the present invention, those of ordinary skill in the art is in the principle without departing from the present invention and objective
In the case of above-described embodiment can be changed within the scope of the invention, change, replace and modification.
