In recent years, with the gradual maturity of unmanned aerial vehicle technology, unmanned aerial vehicles are widely applied to national production activities such as power transmission line inspection, national soil resource measurement, agriculture and forestry pesticide spraying, natural disaster emergency management and the like.
With the gradual promotion of the low-altitude airspace open policy, the total running amount of the domestic unmanned aerial vehicles is rapidly increased. In the operation of unmanned aerial vehicle that increases day by day fast, demonstrate the problem that the model is mixed and disorderly, equipment disperses, lacks unified management, introduced a large amount of potential safety hazards for airspace safety and ground personnel safety.
The special unmanned aerial vehicle is a civil unmanned aerial vehicle with the weight of the unmanned aerial vehicle more than 15 kilograms and less than or equal to 116 kilograms, or the total takeoff weight more than 25 kilograms and less than or equal to 150 kilograms. The invention is suitable for all unmanned aerial vehicles, but the unmanned aerial vehicle smaller than the specific unmanned aerial vehicle is not in the supervision range, the related operation data and records do not need to be reliably filed, the unmanned aerial vehicle larger than the bit point unmanned aerial vehicle is managed according to navigation, and the problem of data evidence can be solved by the method.
In order to deal with potential safety hazards in the operation of unmanned aerial vehicles and standardize the operation of the unmanned aerial vehicles, and ensure the life and property safety of national airspace and ground personnel, airspace safety supervision departments set out a series of regulations, consultation notices and industrial standards, such as light and small unmanned aerial vehicle operation regulations (AC-91-FS-2015) -31), specific unmanned aerial vehicle trial operation management regulations (AC-92-2019-01), light and small civil unmanned aerial vehicle flight dynamic data management regulations (AC-93-TM-2019-01), unmanned aerial vehicle cloud system interface data regulations (MH/T2009-2017 and the like, so as to realize the unified supervision on the operation of the unmanned aerial vehicles.
In conventional aircraft operation supervision, the primary means of supervision is the review of various operational-related records. The production of unmanned aerial vehicles is accompanied by the explosive development of information technology, so that the operation of unmanned aerial vehicles has natural digital characteristics, and the traditional supervision mode relying on paper record is difficult to apply. Considering unmanned aerial vehicle operation and the difference of having the man-machine operation, if adopting paper record supervision not only inefficiency to the unmanned aerial vehicle operation, can hinder the healthy development of unmanned aerial vehicle industry moreover.

The general block chain technology can solve the problems of changeability and extinguishability of electronic data to a certain extent through application of the distributed book technology. However, the operation data of the unmanned aerial vehicle is complex and variable, so that the problem that the block chain technology cannot meet the operation event/accident investigation of the unmanned aerial vehicle easily occurs in the application of the operation data storage certificate of the unmanned aerial vehicle, that is, whether the electronic data can comprehensively meet the operation supervision requirement of the unmanned aerial vehicle is difficult to guarantee, and therefore the block chain technology is difficult to actually develop in the application of the operation data storage certificate of the unmanned aerial vehicle.

The corresponding public key should be synchronously sent to a data supervisor, namely a civil aviation bureau, which needs to continuously perform qualified approval and supervision on the operation process of the unmanned aerial vehicle.
(2) And allocating a control end ID (identity), namely UACID:
the operation control station (also called ground control station) comprises: intelligent terminal, remote controller, ground control car or automatic control system etc.. The normal UACID should be the same as the MAC address of the operation control station, i.e., the MAC address of the operation control station is used as the UACID. And the UACID is taken as a main body, and a digital certificate private key is issued for encryption of flight mission data and trusted data tracing. The corresponding public key should be sent to the data administrator synchronously.
During practical application, after the unmanned aerial vehicle holder registers the real name of the unmanned aerial vehicle holder, the data supervisor can distribute an unmanned aerial vehicle ID to each unmanned aerial vehicle. The MAC address of each operation control station can be distributed by the owner of the unmanned aerial vehicle.
(3) The data generated in the operation of the unmanned aerial vehicle are encrypted and then transmitted to the operation control station:
the data includes operation data and sensor data, and specifically includes: longitude, latitude, altitude, elevation, airspeed, track angle, etc. And after the data is signed by using a private key corresponding to the UAVID, the data is sent to the operation control station at a specific frequency.

The repair order data is encoded as follows:
the maintenance task number (1 + UAVID + maintenance date YYMMDD +4 digit sequence number), the maintenance place (3 digit letter), the maintenance type (0 is routine maintenance, 1 is regular inspection maintenance, 2 is AD/SB execution, 3 is temporary troubleshooting), the maintenance object number (4 word code, can refer to ATA section number) are connected in series in turn to obtain the maintenance task data code, and the data can adopt "+" as a separator.
The inspection task data is encoded as follows:
the inspection task data refers specifically to the data of the pre-flight inspection, and the data is encoded as follows: the inspection task number (2 + + UAVID + inspection date YYMMDD + 4-bit sequential number) and the flight task number (0 + UAVID + flight date YYMMDD + 4-bit sequential number) are sequentially connected in series to obtain the inspection task data code, and the data can adopt "+" as a separator.
And the operation control station respectively encodes the three data according to different tasks.
EventData is formed by connecting the codes (flight mission data code, maintenance mission data code and inspection mission data code) in series, and the data uses "+" as a separator. The flight mission, the maintenance mission and the inspection mission are three parallel mission types which need to be stored with evidence, aiming at different mission types, data which need to be stored with evidence are different, for example, some missions may only be the flight mission, the flight mission data coding is used as EventData, some missions comprise the flight mission and the maintenance mission, the flight mission data coding and the maintenance mission data coding are connected in series as EventData, and the like.
(6) The operation control station processes the flight event investigation corroborative data and the privacy data to obtain evencedata:
flight event survey corroboration data and privacy data include: flight system logs, flight charts, flight mission books, and the like. The flight system log is data generated by the flight control system according to the operation data or the sensor data in the step (4), the flight chart is generated by an unmanned aerial vehicle navigation system or an unmanned aerial vehicle fence system, and the flight mission book is a manually filled PDF file or a database record, which are both existing data and are not described again.
And (6) extracting the abstracts of the relevant electronic records such as the flight control system logs, the flight chart, the flight mission book and the like by using the existing SM3 algorithm, wherein the abstracts are 256-bit character strings, the abstracts form the evencedata, the data volume is compressed by extracting the abstracts, and meanwhile, the flight detailed data, the flight control system logs and other privacy data are effectively protected on the premise of ensuring the normalization of the specific type of unmanned aerial vehicle operation data and the authenticity of the uplink data.
(7) Operating the control station to upload task data to the block chain, namely, uplink:
the operation control station takes the eventData and the eventData as original text of block chain chaining data (namely chaining the eventData and the eventData), performs data chaining work through a block chain information issuing mechanism after finishing data signature calculation, and obtains a chain on-chain evidence storage address of the flight event of the unmanned aerial vehicle.
(8) After the supervision node acquires the uplink data of the operation control station, data verification and identity verification are carried out, if the verification is passed, supervision index data (namely analysis EventData) in the uplink data are analyzed, the supervision index data comprise a flight task number, UAVID (unmanned aerial vehicle) and flight time, supervision data storage is completed together with the rest uplink data (namely the EventData), data obtained by analyzing the EventData are stored, and meanwhile the EventData are directly stored.
The supervision node is a primary or secondary node controlled by a data supervisor on the block chain, and the supervision node obtains the uplink data by using the evidence storage address in the step (7). Both the data verification and the identity verification are realized through a key pair, namely, through the digital certificate in (1) or (2).
The method further comprises:
(9) And (3) verifying data in event investigation, and analyzing and utilizing the data:
when event investigation occurs later and record calling analysis is needed, the unmanned aerial vehicle operator presents the evidence storage address of the investigated event or UAVID of the unmanned aerial vehicle to the data supervisor, and meanwhile, investigation evidence data or related record texts with privacy data are provided additionally (the data are stored by the operator). After receiving the relevant data, the data monitoring party completes the verification of authenticity, integrity and validity of the data (the verification is realized by adopting the existing method, and the data is not followed any more). When the data passes the verification and is confirmed to be correct, the related data (including the data existing on the blockchain and the original data without uplink (for evencedata, the uplink is the abstract value of the data original text, but the part of the data original text is not uplink, namely the original data without uplink) can be used as an original for further business investigation, when the verification is required, an unmanned aerial vehicle operator presents the data original text, extracts the abstract and compares the abstract with the uplink abstract, if the abstract is consistent, the related data original text is considered to be true and credible, otherwise, the data original text is considered to be tampered), and the specific business investigation method is the prior art and is not repeated herein.

and (4) certificate storage authority: refers to that uplink of operation data can be completed by the node.
And (3) consensus authority: the verification of the authenticity and the integrity of the uplink data can be completed through a consensus algorithm.
And (4) verifying the authority: it means that whether the data is already chain-credited can be completed through the verification algorithm.
Configuring the authority: the method can release the uplink data model in time according to the relevant supervision requirements of the unmanned aerial vehicle operation data evidence storage, and modify the structure and content of the relevant data in the EventData.
The access authority refers to the certificate storage authority of the first-level node or the second-level node which can be called in a limited way after identity verification.

and A2, the management node provides data consensus service for the primary node and the secondary node and participates in voting of data authenticity and integrity. Data can be issued to the first-level node and the second-level node, and data chaining is achieved;
and A3, the primary node provides data consensus service for the secondary node and participates in voting of data authenticity and integrity. Data can be issued to the management node and the secondary node, and data uplink is realized;
a4, the secondary node can issue data to the management node and the primary node to realize data chaining;
and A5, the application node can call the data uplink function of the primary node or the secondary node according to the authorization to complete the uplink release of the data.
(2) All nodes on the block chain are in a real-name system, and all nodes need to be configured with digital certificates to complete verification of identity authenticity and ensure safety of data chaining.
(3) The integrity of uplink data on the block chain is completed by the management node and the primary node through a consensus algorithm. Verification of data integrity is generally accomplished in a 100% consistent manner, i.e., the verified data needs to be 100% identical to the data of the management node and the primary node.
The invention also provides an unmanned aerial vehicle operation data storage system, which comprises:
the ID distribution unit is used for distributing the ID of the unmanned aerial vehicle to the unmanned aerial vehicle and distributing the ID of a control end to an operation control station of the unmanned aerial vehicle;
the encryption unit is used for encrypting data generated in the operation of the unmanned aerial vehicle and transmitting the encrypted data to the operation control station;
a receiving unit for receiving, verifying and storing data;
and the encoding processing unit is used for encoding the operation task data to obtain EventData when the unmanned aerial vehicle finishes operation, and processing the flight event investigation corroboration data and the privacy data to obtain Event data:
the uplink unit is used for uploading the eventData and the evencedData serving as uplink data to the block chain and obtaining an on-chain evidence storage address of the flight event of the unmanned aerial vehicle;
and the checking unit is used for carrying out data checking and identity checking on the uplink data, analyzing the EventData to obtain an analysis result if the checking is passed, and storing the analysis result and the Event data together.
The examples of the invention are as follows:
as shown in fig. 3, the present embodiment includes the following steps:
step 1: unmanned aerial vehicle (real name registration number: UAV 12345678) flies data or sensor data to the operation control station according to the established frequency (generally 5 seconds 1 time), including longitude (accurate to 7 bits after decimal point, can multiply 7 bits after 10), latitude (accurate to 7 bits after decimal point, can multiply 7 bits after 10, transmit), height (accurate to 2 bits after decimal point, can multiply 2 bits after 10, transmit), altitude (accurate to 2 bits after decimal point, can multiply 2 bits after 10), speed (accurate to 1 bit after decimal point, can multiply 10, transmit), track angle (accurate to 1 bit after decimal point, can multiply 10, transmit). The data transmission may use the https protocol and the data may be concatenated, separated by a "+".
Step 2: and the operation control station receives the flight data and determines the authenticity and integrity of the data through the public key of the UAVID corresponding to the digital certificate. If the authenticity and integrity checks are passed, the operation control station stores the current set of flight data. After the flight mission is finished, the original text data of the flight mission (i.e. the EventData obtained by encoding) is obtained in a manual entry or system reading mode, for example, an unmanned aerial vehicle executing a patrol mission for 2 hours at an airport in great Khingan is only provided with the flight mission in this embodiment, and therefore the EventData is: "0UAV12345678202112051234+ JGD 7200+120000+140000+115000+141000+32.15+10.16+0"
Meanwhile, for evidence data including information such as flight charts, flight control system logs, flight data packets and the like, the SM3 algorithm is utilized to calculate the abstract of 256 bytes to serve as the evencedata of the flight mission.
Each flight task corresponds to one EventData and one evencedata
And step 3: and the operation control station takes the evencedata and the EventData as all evidence-storing data of the flight to carry out data chaining on the coded data. If the unmanned aerial vehicle operator is a medium-large company, the total flying amount is large, and high requirements are placed on the data concurrency amount and the evidence storage speed, data uplink can be performed in a self-established node mode (primary or secondary). If the unmanned aerial vehicle operator is a small-sized company, the total flying amount is less, and data chaining can be performed through the appointed primary node or secondary node in an authorized access mode.
And 4, step 4: the primary node or the secondary node realizes the diffusion transmission and the distributed storage of the uplink data by using the relevant characteristics and technologies of the block chain, and ensures the authenticity, the integrity and the non-tamper property of the data.
And 5: and the characteristic unmanned aerial vehicle operation safety monitoring party uses the management node or the primary node to monitor the block chain data, acquires the chain unmanned aerial vehicle data in time, and confirms the identity of the data sending party and the authenticity of the data per se through data verification and consensus. And if the identity of the data sender is credible and the authenticity of the data is credible, carrying out the next step.
Step 6: the supervisory system analyzes EventData, and the analysis result obtained after analyzing EventData "0UAV12345678202112051234+ JGD 7200+120000+140000+115000+141000+32.15+10.16+0" (EventData in this embodiment only has flight task code) in this example is as follows:
Meanwhile, according to the flight mission and the unmanned aerial vehicle number, relevant information of an unmanned aerial vehicle operator, unmanned aerial vehicle airspace approval and unmanned aerial vehicle predetermined air routes can be searched and inquired.
And 7: when event investigation, spot check or annual review is required, corresponding event information (i.e. data monitored in the chain in step 5) can be called from the unmanned aerial vehicle supervision system.
And 8: the unmanned aerial vehicle operator provides the original files of the relevant evidence data, flight chart, flight control system log, flight data packet and other information.
And step 9: and the supervisor verifies the authenticity and credibility of the data provided by the unmanned aerial vehicle operator by using the block chain verification function and the timestamp information.
Step 10: the supervisor conducts an event survey or data analysis.
Through the steps, an unmanned aerial vehicle operator can timely complete the storage of the operation data of the unmanned aerial vehicle after a task, and the requirement of unmanned aerial vehicle supervision on data timeliness and authenticity is guaranteed to be met. Meanwhile, according to the method, the unmanned aerial vehicle operator can ensure the normalization of the uplink data, and the subsequent investigation and supervision are facilitated. Moreover, the unmanned aerial vehicle supervisory part can break away from unmanned aerial vehicle operator's system completely, independently develop unmanned aerial vehicle operation supervision and investigation work, and need not to visit unmanned aerial vehicle operator's system, and relevant investigation and analysis can not lead to unmanned aerial vehicle operator's system to shut down, can not cause adverse effect to unmanned aerial vehicle operator's normal production behavior.
Finally, it should be noted that the above-mentioned technical solution is only one embodiment of the present invention, and it will be apparent to those skilled in the art that various modifications and variations can be easily made based on the application method and principle of the present invention disclosed, and the method is not limited to the above-mentioned specific embodiment of the present invention, so that the above-mentioned embodiment is only preferred, and not restrictive.
