Detailed description of the invention
The airfield runway foreign body at night that with specific embodiment, this utility model provided below in conjunction with the accompanying drawings, mill
Damage detecting system is described in detail.
As it is shown in figure 1, the airfield runway foreign body at night of this utility model offer, wear detecting system include:
Microprocessor 1, grid light sources 2, photographic head 3, display 4, memory module 5, serial communication
Module 6 and host computer 7；Wherein: microprocessor 1 respectively with grid light sources 2, photographic head 3, display
4, memory module 5 and serial communication modular 6 connect, and memory module 5 is connected with serial communication modular 6,
Serial communication modular 6 is connected with host computer 7.
Described microprocessor 1 uses the tms320c6748dsp development board of TI company, and it utilizes numeral
The image information that photographic head 3 gathers is stored in memory module 5 by signal processing technology, then by image
It is shown on display 4, and sends above-mentioned image to host computer 7 by serial communication modular 6, supply
Host computer 7 processes in real time and shows.
As in figure 2 it is shown, the described grid light sources 2 high grid matrix light source good, intensive that is rectilinearity,
The head of airport inspection car it is erected in the way of front portion is downward-sloping.Its light sent projects runway
A big grid being made up of multiple little grids can be formed after on, as it is shown on figure 3, between light and runway
Angle α is 30 45 °.
Described photographic head 3 uses MT9V034 infrared camera, in the way of parallel with grid light sources 2
Being erected at the head of airport inspection car, input clock is 27MHz, and photosensitive area is 1/3 inch, pixel
Type is Wide-VGA, and pixel is 752*480, it is possible to adapts to light and shade and changes greatly, surrounding ratio
Dark occasion.
Described display 4 is 4.3 cun of TFT liquid crystal display screens, carries LCD backlight 20V booster circuit, single
3.3V power supply is powered.
Described memory module 5 is Double Data Rate synchronous DRAM, is used for storing photographic head 3
The image gathered.

Described host computer 7 is background monitoring computer, is used for controlling microprocessor 1 and completes runway information
Gather and process in real time and show runway information.
The airfield runway foreign body at night, the wear detecting system operation principle that are now provided by this utility model illustrate
As follows: when airfield runway crack, abrasion and foreign body are detected by needs, first to be safeguarded people by runway
Member's driving airport inspection car, to region to be detected, is then turned on native system, and controllers utilizes host computer 7
Send an instruction of starting working to microprocessor 1, under the control of microprocessor 1, be arranged on airport
Forward downward is launched light by the grid light sources 2 of inspection car head, this light project on runway after meeting
Form a big grid being made up of multiple little grids, if as it is shown on figure 3, big grid place on runway
Region the most smooth, there is no crack, abrasion or foreign body, grid matrix bright line will be very straight, and such as
Really there is impaired position in the region at big grid place on runway or there is foreign body, corresponding grid matrix
Bright line will produce certain bending or deformation, as shown in Figure 4.Meanwhile, flat with grid light sources 2
The mode using progressive scan is gathered the view data at big grid, then profit by the photographic head 3 that row is installed
With the A/D converter carried, the above-mentioned view data belonging to analog data is carried out analog digital conversion, pass afterwards
Giving microprocessor 1, microprocessor 1 is stored in memory module 5 after above-mentioned view data being processed
In, image is shown on display 4 simultaneously；When controllers utilizes host computer 7 to micro-process
When device 1 sends image uploading instructions, microprocessor 1 is by the view data of storage in above-mentioned memory module 5
It is uploaded to host computer 7 by serial communication modular 6.First view data that host computer 7 will receive
It is transformed into the two-dimensional matrix of suitable size, then image data restoration is become first image, afterwards with first
Image is as benchmark, and sets an array and preserve, after second view data transmits,
Carry out processing according still further to said method and obtain second image；Afterwards two images are located accordingly
Reason, after process, same area become 0, zones of different become 1, the district that will change in image
Territory remains, and no the region of change does not becomes 0；If there is not breakage, foreign body, then two figures in runway
Just becoming full 0 matrix after subtracting each other, at this moment the display result on display screen is a black figure；If one
Opening image is in damaged runway collection, then, after two image subtractions, display result is the two of damaged part
Value grating image, the region that this image is corresponding is damaged area, and therefore controllers can be intuitively
Observe the eroded area information of runway.
It addition, the size of grid determines foreign body, damaged size can be detected.Too small grid light beam
The interference effect of a light interfascicular can be formed between two light beams, thus whole testing result can be affected,
Therefore the size of grid should in the light of actual conditions be adjusted.
