Specific implementation
The present invention is described in detail with reference to the accompanying drawing:
(1) system building by mission payload, information process unit, defends logical link connection (such as Fig. 1).Wherein mission payload
Including SAR radar, optoelectronic device, electronic reconnaissance equipment, which is information source；Information process unit, this is partially completed information
Acquisition, processing, tissue and transmission；Defending logical link is radio transmission apparatus.
(2) a kind of method for unmanned aerial vehicle onboard information processing and organizing transmission, specifically includes the following steps:
(3) by the way of the bandwidth constraint of end, as the time sharing transmissions of Various types of data, data compression process provide according to
According to, while compressing data processing provides input；
Information process unit external interface is as shown in Figure 2.
The data that logical wireless transmission bandwidth and mission payload are sent are defended in setting, need to handle the data of transmission all to every kind
An output bandwidth is distributed, the frequency of compression ratio and output is adjusted with the output bandwidth.There are following relationships:
Wherein MkThe bandwidth value of kth kind data is distributed in expression, and A indicates link bandwidth value.It should be noted that for not
The bandwidth of compressible data, distribution should be not less than its original size.
Based on the processing mode, information process unit is divided into data organisation module and compressing processing module, such as Fig. 3 institute
Show, wherein compressing processing module carries out compression processing according to the data of " each data bandwidth allocation " to input, realizes compression processing
The data volume that module exports every kind of data is the bandwidth value distributed, and data organisation module is passed to as unit of frame；Data organization
After module receives a frame data, sends data to and defend logical link.
(4) using H.264, by the way of JPEG2000 mixing compression, take reasonable compress mode for different types of data
It is handled；
Since the data that mission payload generates have an image class, video class, information process unit is according to the types of every kind of data
Mark, takes different data types different processing modes, the data of video class is pressed using H.264 algorithm
Contracting；Compression processing is carried out using JPEG2000 algorithm for image class data.Data flow diagram is as shown in Figure 4.
(5) feedback mechanism, dynamic adjusting data flow are used in information inside processing transmission process；
In fact, in use, due to factors such as scene changes, the data volume of compressing processing module output is often
Bandwidth value beyond setting, to will lead to two kinds of possible phenomenons:
If the buffer area a) in data organisation module is larger, the data exceeded can be cached, and caused data transmission to exist and prolonged
Shi Xiaoying；
If the buffer area b) in data organisation module is smaller, the data exceeded can overflow, and lead to loss of data.
Obvious two kinds of phenomenons are all unable to satisfy actual operation requirements, and the phenomenon that throws into question has its source at compression
Reason module just secures compression relevant parameter after the result for receiving bandwidth allocation, and cannot respond to what comes into a driver's variation bring influences.
Therefore need to take compressing processing module antifeedback measures, principle is as shown in figure 5, increase one instead to compressing processing module herein
Feedback signal, when causing compressed data volume to cross setting value due to what comes into a driver's reason of changes, data organisation module just can not be timely
It takes the data in buffer area away, can thus set high-low threshold value, when the data volume in buffer area is more than high threshold,
Trigger feedback signal.Compressing processing module adjusts compression parameters when receiving feedback signal, such as improves compression ratio, reduces frame
Rate etc., to reduce the size of data after compression.If the data volume in buffer area is lower than threshold ones, compressing processing module
Work according to benchmark compression parameters.
(6) by the way of information decomposition, data are decomposed into primitive transmission in data transmission procedure；
Setting one sends radix, and reality calculates the proportionate relationship of each data by the bandwidth meter of distribution when sending, then with hair
The multiple of radix is sent to be sent.
(7) in the way of time sharing transmissions, according to the strategy of bandwidth allocation, Various types of data timesharing is passed using link
It is defeated.
Compare schematic diagram 3, wherein compressing processing module compresses the data of input according to " each data bandwidth allocation "
Processing, the data volume for realizing that compressing processing module exports every kind of data is the bandwidth value distributed, and data are passed to as unit of frame
Molded tissue block；After data organisation module receives a frame data, as unit of sending radix, multiple data packets are cut into, according to band
Wide ratio sends Various types of data, and data processing glibly and transmission process can be realized in this way inside information process unit.
Data organisation module internal logic figure is sent out data, data group as shown in fig. 6, sending caching with cbr (constant bit rate)
It knits module to recycle according to the ratio of bandwidth allocation to cache writing data is sent, suspends write operation after sending data cached full；
Cache available free recovery write operation.

Infrared video: 30fps, every frame image size are as follows: 640 × 512；
Electronic reconnaissance data: data volume size is 0.1Mbps；
It sets and defends logical link bandwidth as 2Mbps；
Firstly, it is as follows to distribute each data bandwidth:
SAR image: 0.5Mbps；
Visible light video: 0.8Mbps；
Infrared video: 0.5Mbps；
Electronic reconnaissance data: 0.1Mbps；
Then, setting SAR image is compressed using JPEG2000 mode, it is seen that light video, infrared video use are H.264 square
Formula compression, electronic reconnaissance data are not compressed；The dynamic buffering size of feedback effect has been set as 5 frame images.
Finally, the primitive size for setting data transmission does not send 1KB's as a result, as 1KB, while according to bandwidth allocation
Electronic reconnaissance data just send the SAR image of the visible light video of 8KB, the infrared video of 5KB, 5KB.Pass through unmanned aerial vehicle station
It receives the data for defending logical link and parses and check that the actual effect of data transmission is as shown in Figure 7.
The experimental results showed that the method for the unmanned aerial vehicle onboard information processing and organizing transmission proposed using this patent, firstly,
Mode based on end bandwidth constraint provides foundation to the time sharing transmissions of Various types of data, data compression process, improves wireless
Bandwidth availability ratio, compressing data processing simultaneously provide input；Then, using H.264, JPEG2000 mixing compression side
Formula takes different compress modes for different types of data, improves the validity of data processing on the whole；Meanwhile information
The feedback mechanism used in internal processes can effectively avoid the problem that the data ultra-wide band that data compression generates, and solve wireless
Transmission data lose data problem caused by overflowing；In addition, by the way of information decomposition, by data point in data transmission procedure
Solution is primitive, and the real-time that can effectively promote transmission is transmitted in a manner of primitive；Finally in the way of time sharing transmissions, according to bandwidth point
Various types of data timesharing is transmitted using link, realizes the effect of parallel transmission by the strategy matched.The application method is to unmanned plane
Transmission, the use of unmanned aerial vehicle station information, information acquisition of airborne information etc. bring huge use value.
