Description
Technical field
The utility model relates to a kind of supplementary observation device that makes things convenient for vehicle drive to use, specifically a kind of infrared thermal imaging assistant equipments on board.
Background technology
In the military affairs, the use of high-tech such as, photoelectricity trick hidden along with smoke screen, cause the low visibility of vehicle drive environment, add on often by harsh weather such as dense fog, sand and dust, make the vehicle drive personnel usually can't correctly observe the place ahead road conditions, hindered the cruising of vehicle and the normal performance of contained equipment effect.At present, add the lll night vision assistant equipments on board at some on the civilian or military vehicle.The use of this equipment can help human pilot to see the place ahead road conditions clearly at night, but be difficult to play a role under bird-walking weather conditions such as dense fog, dust storm.In addition, this lll night vision assistant equipments on board also have viewing distance short, be subject to high light blinding etc. and use defective.
The utility model content
The purpose of this utility model just provides a kind of influence of high light blinding, infrared thermal imaging assistant equipments on board that can normally use of not being subjected under round-the-clock situation.
The utility model is achieved in that
This infrared thermal imaging assistant equipments on board includes:
---by infrared lens and stare the infrared detection head that the infrared detecting unit array connects to form, be used for the detection of remote scenery heat picture, generate electronic image signal;
---image filtering noise reduction process circuit is used for electronic image signal is gathered and handled, and synthesizes vision signal;
---conversion of signals and interface circuit are used for the conversion and the output of vision signal;
---display is used to show the scene image that detects;
---automatic temperature-controlled and defrost unit is used for the frosting on conditioning equipment working temperature and the elimination detecting head.
Key points in design of the present utility model is exactly to utilize the non-refrigeration of little pixel of staring in the infrared detecting unit to stare infrared focal plane array, combining image filtering noise reduction process circuit, the electronic image signal that is generated by infrared detection head is gathered and the filtering noise reduction process, realized passive detection and demonstration thus remote scenery heat picture.Compare with the driving ancillary equipment that adopts the lll night vision fabrication techniques, the utility model can normally use under round-the-clock situation, is not subjected to the influence of high light blinding; And the configuration of automatic temperature-controlled and defrost unit also can make this device adapt to wider temperature range and complicated weather condition, thereby under the cold environmental condition, also can guarantee the normal use of this device effectively in the open air.
Major technique characteristics of the present utility model: the one, adaptability is strong.Owing to adopted infrared detector array as the core devices of surveying recognition objective, therefore can penetrate battlefield smog, sand and dust and dense fog etc., carry out round-the-clock observation work.Owing to disposed automatic temperature-controlled and defrost unit, make this device can be to the temperature environment self adaptation of broad.The 2nd, security of system is good.The infrared ray that this device gives off owing to the observed pattern detection of a target that is the employing imaging and passive imaging so do not need to any type of electromagnetic wave of external radiation, therefore can be realized the work of mourning in silence, and has strengthened disguise and fail safe that equipment uses thus.The 3rd, antijamming capability is strong.This device is owing to adopt the infrared imaging principle, spectral range is narrower, frequency range from electromagnetic interference commonly used is far, thus can not be subjected to the interference of extraneous forceful electric power magnetic environment, and overcome traditional lll night vision assistant equipments on board and rely on microvision, subject to that high light disturbs and shortcomings such as destruction.
The utility model reasonable in design, easy and simple to handle, can make the vehicle drive personnel by day, discern road, landform, road sign, vehicle and pedestrian under the adverse circumstances such as night, sand and dust, dense fog and smoke screen, thereby improved the auxiliary supportability that various types of vehicles is driven, guaranteed the cruising of vehicle and the normal performance of contained equipment effect.
Description of drawings
Fig. 1 is a circuit structure block diagram of the present utility model.
Fig. 2 be automatic temperature-controlled and defrost unit in the structural representation of defrost mechanism.
Embodiment
As shown in Figure 1, the utility model is by infrared lens 1 and stares infrared detecting unit array 2 and connect to form infrared detection head, is used for the detection of remote scenery heat picture and generates electronic image signal.The output map interlinking of infrared detection head is gathered and the filtering noise reduction process by the electronic image signal of 3 pairs of receptions of image filtering noise reduction process circuit as the input of filtering noise reduction process circuit 3, synthesizes vision signal then.The output of image filtering noise reduction process circuit 3 connects conversion of signals and interface circuit 4, carries out the conversion of vision signal by conversion of signals and interface circuit 4, outputs to display 5 then, demonstrates the scene image that infrared detection head detects.
In this device, also be connected to the automatic temperature-controlled and defrost unit 6 that is used for the conditioning equipment working temperature and eliminates the detecting head frosting.Automatic temperature-controlled and defrost unit 6 includes automatic temperature-adjusting control circuit and defrost mechanism.The automatic temperature-adjusting control circuit is surveyed the environment for use temperature of infrared detection head by thermosensitive probe.When ambient temperature is lower than subzero 5 ℃ or when being higher than 35 ℃, just control attemperating unit and suitably regulate, to keep suitable operational environment.Defrost mechanism in the automatic temperature-controlled and defrost unit 6 is in the place ahead of infrared lens optical protection window 7 to be housed as shown in Figure 2, is provided with electrothermal mechanism 8 and fan 9 at an end of air duct 10, and the other end of air duct 10 leads to the outside of optical protection window 7.When the needs defrost operation, press " defrosting " button on the device panel, electrothermal mechanism 8 starts, and temperature rises to 80 ℃, and keeps stable.Start with aft-fan 9, mixed hot-air is sent to the outer surface of optical protection window 7 by air duct 10, make the optical protection window be among the flowing of hot-air, keep temperature equalization on the inside and outside surface of optical protection window, thereby reach defrosting and antifog purpose.
Stare infrared detecting unit array 2 and other each circuit structure and interface etc. in this device, all can adopt existing known various circuit structures and concrete device to connect to form.Infrared detection head is installed on outside the car body, and other parts are installed in the casing, forms control cabinet, is loaded in the car body, is convenient to driver's operation control and observation.
Native system is when work, and object scene such as the road of vehicle front, landform image on the array surface of staring infrared detecting unit array 2 by infrared lens 1.Stare infrared detecting unit array 2 optical imagery of object scene is carried out opto-electronic conversion, form electronic image signal corresponding to each pixel cell.3 pairs of these electronic image signals of DSP/FPGA filtering noise reduction image processing circuit are gathered and are handled, filtering image noise and most electronic noise, and electronic image signal is synthesized the vision signal of standard N TSC standard or pal mode.Vision signal after synthetic is sent in the control box that is installed in the car through conversion of signals and interface circuit 4, after further handling, outputs to display 5 and shows.So far, the driver just can carry out the driving of vehicle by observing the scene image on the display screen.
