Description

Method and system for unmanned aerial vehicle information interaction by using safety short message

Technical Field

The invention relates to the field of communication and unmanned aerial vehicles, in particular to a method and a system for carrying out information interaction on an unmanned aerial vehicle by transmitting a short message with a specific safety mechanism through a communication public network.

Background

An Unmanned Aerial Vehicle (UAV) is an Unmanned Aerial Vehicle operated by a radio remote control device and a self-contained program control device. An unmanned machine is in fact a generic term for unmanned aircraft.

Unmanned aerial vehicle Systems (UAS), also known as Unmanned Aircraft Systems, refer to a system of drones, associated remote control stations, required command and control data links, and any other components specified in an approved model design. In short, an airplane is provided with a remote control device.

The market and the application of the unmanned aerial vehicle are developing vigorously at present, and the unmanned aerial vehicle yield reaches 1800 hundred million yuan by 2025 years, and the annual average speed is increased by more than 25%.

In recent years, with the rapid development of the unmanned aerial vehicle technology, the unmanned aerial vehicle industry is also developed vigorously in China. Because unmanned aerial vehicle has the characteristics such as lower, unmanned casualty risk, survivability are strong, mobility is good, convenient to use, more and more industrial application constantly appears, if fields such as aerial photography, agriculture and forestry plant protection, electric power are patrolled and examined and have used unmanned aerial vehicle to replace traditional general airborne vehicle to engage in relevant operation activity on a large scale. With the increasing holding amount and the gradual increase of popularity of the unmanned aerial vehicle, the unmanned aerial vehicle becomes a main user of a low-altitude airspace in China after a traditional general aircraft. However, due to the characteristics of low speed and small speed (low altitude and low speed small aircraft), the monitoring of the flight of the unmanned aerial vehicle is difficult to be found by radar, and the main problem of the low altitude airspace monitoring in China is solved.

The flight control system of the unmanned aerial vehicle is a core component of the unmanned aerial vehicle system and is used for controlling the flight of the unmanned aerial vehicle, the performance of the flight control system directly influences the flight performance and the flight quality of the unmanned aerial vehicle, and the flight safety of the unmanned aerial vehicle is directly influenced. The flight control system collects flight state data measured by each sensor in real time, receives control commands and data transmitted by an uplink channel of the ground measurement and control station through the airborne wireless digital terminal, and outputs the control commands to the execution mechanism through calculation and processing so as to realize control of various flight modes and management and control of task equipment in the unmanned aerial vehicle; meanwhile, the state data of the unmanned aerial vehicle, an engine, an airborne power system and the working state parameters of the task equipment are transmitted to an airborne radio data terminal in real time and are transmitted back to the ground measurement and control station through a radio downlink channel.

At present, the data transmission communication modes of the unmanned aerial vehicle mainly comprise three types: radio, WiFi, and operator public networks. The preferred mode of the unmanned aerial vehicle is a radio station mode, 840.5-845MHz, 1430-1444MHz and 2408-2440MHz frequency bands are planned to be used for the unmanned aerial vehicle system according to radio frequency division rules of China and frequency spectrum application conditions, and the unmanned aerial vehicle is generally applied to various industrial unmanned aerial vehicles such as military police, plant protection, aerial survey and the like. Secondly, a data communication mode of WiFi is applied, the frequency band is commonly selected to be 2.4GHz, and the data communication mode also comprises civil radio transmission modes such as Bluetooth and the like similar to the WiFi. And finally, a 3G/4G public network of a mobile operator is adopted, the network of the mobile operator is usually optimized for covering the ground, the signal coverage is poor at a position 300 meters above the air, the normal operation height of the unmanned aerial vehicle during flying is 300-1000 meters above the air, and the unmanned aerial vehicle is difficult to acquire corresponding signals at a position above 300 meters, so that the real-time communication between a high-precision foundation reinforcing base station and an airborne mobile station cannot be ensured, and the current practical application is few.

However, it is noted that the public network of the operator has the widest geographical coverage, and with the gradual popularization of the commercial personal unmanned aerial vehicles, it is one of the most possible development directions to utilize the public network of the operator to perform communication transmission of the unmanned aerial vehicles so as to fulfill the corresponding regulatory requirements.

The uplink communication link of the drone mainly conveys the following information:

flight path data, flight control instructions, airborne accessory device control instructions, position update information, and the like;

the downlink communication link of the drone mainly transmits the following information:

position information of the aircraft, images and data of onboard accessories, flight status information, and the like.

With the evolution of Mobile communication networks in China, 2G (Global System for Mobile Communications ) networks gradually turn service emphasis towards the application of the field of Internet of things, and with the reduction of personal services, the possibility of air optimization network deployment exists. Through the analysis of the transmission data of the unmanned aerial vehicle, the data related to the service load of the auxiliary equipment is eliminated, the requirement on the constant speed rate of the flight control data flow of the unmanned aerial vehicle is low, and the data can be borne by the GSM and the extension technology thereof through constructing a short message data packet.

GSM services are mainly divided into two categories, telecommunications services, which provide the user with complete capabilities including terminal equipment functionality, and bearer services, which provide signal transmission capabilities (300bps-9.6kbps) between user/network interfaces.

GPRS is an english abbreviation for General Packet Radio service (General Packet Radio service), is a transition industry from 2G to 3G, is a new bearer service developed on GSM systems, and aims to provide Packet-form data services for GSM users. It is particularly suitable for intermittent, bursty, frequent, small data transfers, but also for occasional large data transfers. The theoretical bandwidth of GPRS can reach 171.2kb/s, and the practical application bandwidth is about 40-100 kb/s.

Edge (enhanced Data Rate for GSM evolution) is an enhanced Data Rate GSM evolution technology. EDGE has mainly adopted a new modulation method in GSM system, i.e. the most advanced multi-slot operation and 8PSK modulation technique at that time. Since 8PSK can expand the symbol-carrying information space of GMSK modulation techniques employed by GSM networks from 1 to 3, each symbol contains 3 times more information than it originally contained. The EDGE technology effectively improves the GPRS channel coding efficiency and the high-speed mobile data standard thereof, and the highest speed of the EDGE technology can reach 384 kbit/s.

In the invention, a GSM short message mode is used as a transmission mode for describing a small data packet short message mode as an instruction of the unmanned aerial vehicle, the mechanism can also be extended and applied to a GPRS/EDGE data technology and a subsequent public network transmission technology, such as 3G WCDMA/4G LTE/5G NR and the like, can be uniformly described as establishing a public network information transmission channel and is used for transmitting the instruction or report message of an unmanned aerial vehicle communication terminal through an air interface, and the message can be provided with an encryption field of security authentication.

The mechanism is also suitable for other types of terminals which receive the information interaction in the mode of the short message of the public network with the security certification small data packet.

If after the 2G (GSM/GPRS/EDGE) network is deployed for air optimization, stable unmanned aerial vehicle data connection can be achieved, unmanned aerial vehicle information can be transmitted in a data connection mode, but because the flight working mode of the unmanned aerial vehicle is complex in channel change, and a large number of unmanned aerial vehicles exist in a cell, long-term stable data bearing is possibly difficult to achieve, and frequent network breaking is possible.

The GSM short message is a storage and forwarding function completed by a short message center, and has a point-to-point working mode and a broadcast working mode.

GSM sends and receives short messages in three modes: BLOCK mode, TEXT mode, and PDU mode. The BLOCK mode is now rarely used; the TEXT mode can only send ASCII code, it can not send Chinese UNICODE code (technically can be used to send Chinese short message, but domestic mobile phone basically does not support); the PDU mode is complex to develop, a special function needs to be written to convert the text into the PDU format, but the PDU mode is supported by all mobile phones, any character set can be used, and the PDU mode is also a default coding mode of the mobile phones. Three types of coding can be used for transmitting and receiving short messages in PDU mode: 7-bit encoding, 8-bit encoding, and UCS2 encoding. 7-bit encoding is used to transmit plain ASCII characters; 8-bit encoding is commonly used to send data messages, such as pictures or ringtones; the UCS2 codes are used to send Unicode characters. The English is coded by Bit7, the maximum length of the user data before coding is 160 bytes, the Chinese is coded by UCS2, the maximum length of the user data before coding is 70 words, the binary data is sent and coded by Bit8, and the maximum length of the user data before coding is 140 bytes.

TABLE 2 example of short message received string format

As the GSM technology has long history, the technical system of the GSM is widely known, the situations such as illegal base stations and the like occur, and the unmanned aerial vehicle needs to pay attention to safety factors when communicating by using a public network to avoid the unfavorable situations such as hijacking and the like.

The traditional short message mainly faces to individual users, false information can be manually identified, and when the unmanned aerial vehicle adopts the short message as an instruction transmission method, a safety verification method needs to be additionally designed.

Therefore, the invention designs a short message improving system with safety characteristic by combining with the communication system of the public network, and the receiving end can verify the relevant instruction, thereby ensuring the information transmission safety.

Several representative encryption methods are described below, and the present invention is illustrated by way of example, without reference to details, and is not limited thereto:

1、MD5

MD5 Message Digest Algorithm (MD5 Message-Digest Algorithm), a widely used cryptographic hash function, can generate a 128-bit (16-byte) hash value (hash value) to ensure the integrity of the Message transmission. The programming of this set of algorithms is specified in the RFC 1321 standard. It should be noted that such algorithms cannot recover the original data from the encoded data.

2. Symmetric encryption

Symmetric encryption uses the encryption method of a single-key cryptosystem, and the same key can be used for both encryption and decryption of information.

The symmetric encryption algorithm is used for encrypting information such as sensitive data, and commonly used algorithms include:

des (data Encryption standard): the data encryption standard is high in speed, and the method is suitable for occasions of encrypting a large amount of data.

3DES (triple DES): based on DES, a block of data is encrypted for three times by three different keys, and the intensity is higher.

Aes (advanced Encryption standard): the advanced encryption standard is the next generation of encryption algorithm standard, and has high speed and high security level;

3. asymmetric encryption

Unlike symmetric encryption algorithms, asymmetric encryption algorithms require two keys: public key (publickey) and private key (privatekey). The public key and the private key are a pair, and if data is encrypted with the public key, only the corresponding private key can be used for decryption.

If the data is encrypted with a private key, it can only be decrypted with the corresponding public key. Since two different keys are used for encryption and decryption, this algorithm is called an asymmetric encryption algorithm.

RSA: the invention is invented by RSA company, is a public key algorithm supporting variable-length keys, and the length of a file block needing to be encrypted is also variable;

dsa (digital Signature algorithm): the digital signature algorithm is a standard DSS (digital signature standard);

ecc (ecc) current customers cryptograph): elliptic curve cryptography

ECC has absolute advantages over RSA in many ways, mainly in the following areas:

1, strong attack resistance. The same key length is many times more robust against attacks.

2, the calculation amount is small, and the processing speed is high. The overall speed of ECC is much faster than RSA, DSA.

And 3, the storage space occupation is small. The key size and system parameters of ECC are much smaller compared to RSA, DSA, meaning that it takes up much less storage space. This is of particular importance for the application of cryptographic algorithms on IC cards.

4, the bandwidth requirement is low. When long messages are encrypted and decrypted, the three types of cryptosystems have the same bandwidth requirement, but the ECC bandwidth requirement is much lower when the cryptosystems are applied to short messages, so that the ECC has wide application prospect in the field of wireless networks.

The operation command usually includes operation code and operation parameter, the sender and receiver sides agree on a uniform parsing format for the transmitted short message, for convenience, the present invention is described by using JSON format, the actual usage is not limited to this (for example, TLV encoding, Tag-Length-Value), JSON (javascript Object notification) is a lightweight data exchange format, which is easy for human reading and writing, and is also easy for machine parsing and generation, JSON can convert the data Object into a string format, for example, { "code": "go", "direction": "up", "speed": "50", "height": "300" }' means a rise to a height of 300 meters at a speed of 50 km/h. The generated JSON character string forms short message content.

FIG. 3 is a single user embodiment of the present invention; as described in relation to figure 3 of the drawings,

the owner of this embodiment carries out communication control flight through SMS mode and unmanned aerial vehicle, and the control cabinet is established in owner's cell-phone department this moment, and owner and unmanned aerial vehicle all have the number of public network settlement to be used for the communication.

After the unmanned aerial vehicle flies to a certain height, the personal wireless network connection between the host and the unmanned aerial vehicle is disconnected, the public network connection mode of the unmanned aerial vehicle is started, an operation instruction is waited,

the main machine sends a short message operation instruction' { "code": "report", "choice": "location" } 'requires to acquire the position information of the unmanned aerial vehicle, and because the unmanned aerial vehicle is not necessarily in a network connection state when an operation instruction is issued, the instruction can be temporarily stored in the short message service center until the unmanned aerial vehicle is sent through the base station after accessing the communication network, and replies the' { "code": "report _ response", "location": "aaa-bbb-ccc", "time": "x: y: z' indicates that the position is at the aaa-bbb-ccc position at the x point y minutes and z seconds, and the short message center forwards the reply short message to the owner after receiving the reply short message.

The main machine sends a short message operation instruction' { "code": "go", "location": "mmm-nnn-kkk" } ', instructing the drone to fly to the site mmm-nnn-kkk, the drone executes the instruction and may feedback acknowledgement' { "code": "go _ response", "location": "mmm-nnn-kkk" }.

FIG. 4 is a multi-user embodiment of the present invention; as described in relation to figure 4 of the drawings,

the embodiment comprises two legal information sources (owner and aviation management department), the two information sources and a control console deployed in a short message service center are in communication connection (including but not limited to fixed network connection, wireless access, mobile phone APP/short message mode and the like) in any mode, and the control console of the short message service center establishes communication contact with an unmanned aerial vehicle through connection with a base station and sends and receives short messages.

Assuming that the unmanned aerial vehicle needs to report the position information every 30 seconds according to aviation management regulations and a no-fly area exists in the flight area, the unmanned aerial vehicle regularly triggers a position report short message and sends a { "code" to a designated number of an aviation management department: "report _ response", "location": "aaa-bbb-ccc", "time": "x: y: z '}', if no public network connection exists, after the public network can be accessed, a stored track report '{ "code': "report _ location _ list", "time": "x: y: z "location": [ "a 1-b1-c 1", "a 2-b2-c 2", "a 3-b3-c 3" ] }', which indicates that from time x: y: z the flight trajectory starting at a contracted time interval.

It should be noted that it is also feasible that the communication terminal of the unmanned aerial vehicle communicates with a plurality of users respectively, but a unified multi-user control center platform is provided, so that user authentication, information sharing and instruction conflict processing procedures can be effectively performed, for example, only the user in the authorized user list can communicate with the unmanned aerial vehicle terminal; when a user needs to acquire the position information of the unmanned aerial vehicle, the console can select the latest and effective position report in a certain time range to directly reply, so that the air interface transmission pressure is reduced; the console can acquire the no-fly zone information of the air traffic control department, and when the user instruction violates the relevant regulations, if the target location enters the no-fly zone, the console can stop forwarding the instruction and feed back the no-fly zone information to the user.

Fig. 5 is an embodiment of adding user identity authentication to the short message content according to the present invention, because the GSM system is widely known, and there are phenomena such as a pseudo base station and a pseudo terminal, and in order to improve the safety of the unmanned aerial vehicle, security authentication needs to be enhanced, in this example, an authentication code field, such as' { "code": "report", "index": "xyz" "verify _ code": "MD 5(index + key)"', generates a verification code (verify _ code) for each instruction according to MD5 algorithm by using instruction sequence number (index) and preset key (key), the receiving end needs to generate the same MD5 verification code according to the sequence number and the agreed key to confirm that the corresponding information passes through effectively to execute the corresponding operation, because the short message transmission has the possibility of being repeatedly transmitted, the receiving end should be executed in increments according to the sequence number to avoid repeatedly executing the same instruction, and the time stamp is used to replace the sequence number when the verification code is generated, which can achieve similar effects, for example, the time stamp is x: y: z' { "code": "report", "time": "x: y: z "verify _ code": "MD 5 (x: y: z + key)"'.

The terminal can also combine other information in the short message, such as whether the number of the sending terminal is in a legal instruction source stored by the local machine, and the like to make comprehensive judgment.

Fig. 6 is an example of processing method agreement according to different information destinations and information sensitivity levels, where a location report of an unmanned aerial vehicle belongs to non-sensitive information, and agreement plaintext is sent, and a user instruction information agreement adopts a method of verifying a user identity using an MD5 key, and when a suspicious base station signal is frequently searched or an abnormal instruction is received many times, because an illegal action is suspected, report information encrypted by an RSA key published by a telecommunication management department is sent to a number of the telecommunication management department. The invention can appoint different encryption modes through different communication objects and different communication contents, thereby achieving the unification of safety and usability.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
