Connect.The day total blindness ultraviolet imagery system includes four days total blindness's ultraviolet imager, and each day total blindness ultraviolet imager is by searching
Control unit is rescued to be controlled.Communication unit is responsible for the communication between ultraviolet search and rescue device and winged keyholed back plate reason computer, and day is complete
The information of blind ultraviolet imager collection is uploaded to winged keyholed back plate reason computer, and manages the instruction adjustment of computer each according to winged keyholed back plate
The imaging contexts of ultraviolet imager.
The day total blindness ultraviolet imager, including：Ultraviolet optics system, filter, enhanced charge-coupled device and letter
Number reading circuit；The ultraviolet optics system is connected with filter input, filter output end and enhanced charge-coupled device
Connection, enhanced charge-coupled device are connected with signal sensing element；The signal sensing element and the input for searching and rescuing control unit
End connection.The ultraviolet optics system includes：Telephoto lens, short-focus lens, length Jiao switch unit and diaphragm control structure, light
Late control structure includes the first diaphragm and the second diaphragm, and the telephoto lens and short-focus lens connect with length Jiao switch unit
Connect, the first diaphragm and the second diaphragm are connected with the search and rescue control unit, and length Jiao switch unit controls with described search and rescue
Unit connects.
Ultraviolet light pools picture into ultraviolet optics system, by only retaining day total blindness's ultraviolet band after filter
Light, enhanced charge-coupled device is eventually entered into, be converted into electronic signal and exported by signal read circuit to search and rescue control list
Member.Filter selects multi-disc absorption-type ultraviolet filter scheme, has higher day blind UV-permeable and non-non-solar-blind band
Cut-off property.Telephoto lens is used to be imaged distant object, coordinates the first diaphragm to be adjusted light-inletting quantity, it can be ensured that mirror
Head obtains more visible image during from far near.During searching and rescuing equipment and moving closer to ultraviolet beacon, long lens
Head gradually increases into image, until image can not be obtained completely, now switches to short-focus lens.Short-focus lens coordinate the second light
Door screen realizes the imaging of latter end.Length Jiao's switch unit, for switching long short-focus lens.Enhanced charge-coupled device is on existing basis
On be improved, pass through coupling high-speed CCD, high speed readout circuit and digital mode signal output（GigE Vision interfaces）, subtract
The duration of output is imaged onto less.
The signal sensing element of first ultraviolet imager 1 is connected with searching and rescuing the video 1# inputs of control unit, and second is purple

The video 4# inputs connection of control unit.The ultraviolet source that ultraviolet beacon is sent pools picture into ultraviolet optics system, leads to
Cross after filter and only retain the light of ultraviolet day total blindness wave band, conveyed after enhanced type charge-coupled device by signal read circuit
To corresponding video inputs, search and rescue control unit is transferred to be handled.
Ultraviolet beacon is fixed on life vest, lifebuoy etc. by search and rescue target, there is provided day total blindness's ultraviolet source signal, by spy
Ultraviolet LED light source and electric power driving module two parts composition at definite divergence angle, possess it is overboard after open and to send day total blindness ultraviolet
The ability of rescue signal.To obtain more than the water surface good omnidirectional's detectivity, in life vest, lifebuoy or need to typically be searched and rescued
Some groups of ultraviolet beacons are reasonably arranged in target.
It is mounted in and is searched and rescued in equipment for convenience of day total blindness's ultraviolet imager, according to specific carrying platform feature, Ke Yixuan
The action actuating mechanism as day total blindness's ultraviolet imagery system above Electric-Optic Turret or support is selected, and is pacified this as an entirety
On carrying platform, the executing agency of the actions such as scanning, locking, tracking is provided as detecting devices.
The identification distance of ultraviolet source intensity and search and rescue system, action time（Not less than 72 hours）Direct correlation.Therefore,
After beacon unlatching, different mode of operations is used according to the time of operation, the working frequency of ultraviolet LED light source is adjusted
System, on the premise of continuous imaging and detection accuracy is not influenceed, can extend safety time；Based on being wanted to beacon weight
It is the simplification that ask, ensures, safe and reliable, Power Management Design is carried out using one-shot battery, the non-once battery of same volume can prolong
The usage time of long power supply.The service band of the ultraviolet beacon is 260-280nm ultraviolet band, and 260-280nm is ultraviolet
The optimal ultraviolet band that imager can be detected.
Research shows that the ultraviolet imager angle of visual field is smaller, and it is more remote to search and rescue distance.Field of view of receiver is with searching and rescuing distance relation as schemed
Shown in 2, the signal to noise ratio in figure is according to the different and different of search and rescue environment.
But if visual field is too small during searching and rescuing, cover sweep time length needed for search and rescue region, it is not easy to quick to find
Target, and blind area be present during aircraft advance, cause search efficiency not high.In order to meet big hunting zone and remote
Contradiction between detection range, the ultraviolet imager of multigroup different angles of visual field can be designed, form a sector search region.
In the present embodiment, day total blindness's ultraviolet imagery system include four ultraviolet imagers, according to the noise of institute's test environment
Than the second ultraviolet imager 2 and the angle of visual field of the 3rd ultraviolet imager 3 are arranged to 60 °, and the first ultraviolet imager 1 and the 4th is ultraviolet
The angle of visual field of imager 4 is arranged to 25 °, and so design causes the search of the second ultraviolet imager 2 and the 3rd ultraviolet imager 3 height
It can reach 787m, the search of the first ultraviolet imager 1 and the 4th ultraviolet imager 4 highly can reach 309m, in lateral extent
Search width can reach 2.7KM.Selected by the present invention day total blindness's ultraviolet imager performance indications：
