Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a communication system for a tethered unmanned aerial vehicle for electric power infrastructure. Background Art

[0002] With the development of drone technology, they are playing an increasingly important role in the inspection and maintenance of power infrastructure. Traditional power infrastructure inspections mainly rely on manpower for ground or direct inspections, which is not only inefficient but also poses safety risks in high-risk environments. Therefore, the use of drones for remote monitoring of power infrastructure has become an effective means to improve efficiency and safety. Drones can be equipped with video and audio monitoring devices to collect real-time data on power infrastructure and transmit the data back to the ground control center for analysis and processing through wireless communication technology.

[0003] At present, some drone systems have been developed for inspection and monitoring of power systems. These systems usually include video capture and basic data transmission functions, and can transmit the collected video data back to the ground station via a wireless network. However, these existing technical solutions face many limitations. First, the problem of data transmission security has not been fully solved, and the data during the transmission process is easily intercepted or interfered. Secondly, the real-time transmission efficiency of data is low. Due to the unoptimized data compression and transmission technology, the data is delayed during the transmission process, which affects the real-time and accuracy of the inspection. The main technical defects of the existing technology are its deficiencies in data security and transmission efficiency. Due to the lack of effective data encryption and optimized transmission technology, the inspection data is easily accessed by unauthorized people during the transmission process, and the data transmission efficiency is low, which cannot meet the needs of remote real-time monitoring. These problems not only limit the scope of application of drone inspection systems, but also affect the effectiveness and security of power infrastructure monitoring.

[0075] The central processing module has efficient data processing capabilities and excellent task scheduling mechanism, ensuring high efficiency and low latency performance when the drone performs tasks.

[0076] Information processing module:

[0077] Function: The information processing module is mainly responsible for collecting image and sound data of the surrounding environment and providing real-time environmental information for the drone. The collected data will be encrypted to ensure the security of information transmission.

[0078] The information processing module is equipped with high-precision image and sound acquisition equipment, and combined with advanced encryption algorithms (such as AES, RSA, etc.), to provide the drone with safe, clear and accurate surrounding environment data.

[0079] Flight status monitoring sensors:

[0080] Function: The flight status monitoring sensor is responsible for real-time monitoring of the flight status of the drone, including but not limited to altitude, speed, direction, etc., and dynamically adjusts the flight of the drone based on the monitored data to maintain a safe distance.

[0081] The flight status monitoring sensor has high sensitivity and accuracy. It can capture the changes in the flight status of the drone in real time, and optimize the flight route and status of the drone through algorithms to ensure flight safety.

[0082] UAV mutual monitoring module:

[0083] Function: The UAV mutual monitoring module is used to monitor the relative position and flight status of multiple UAVs performing tasks, ensure a safe distance between them, and prevent mutual interference and collision.

[0084] The mutual monitoring module uses advanced wireless communication technology and spatial positioning technology to accurately obtain the relative position and flight status information between drones, and make timely adjustments and feedback.

[0085] Communication module:

[0086] Function: The main responsibility of the communication module is to transmit the encrypted environmental image data, encrypted environmental sound data and monitoring data in the power infrastructure back to the ground control center through reliable communication technology.

[0087] Communication module: Adopt COFDM (Orthogonal Frequency Division Multiplexing Coding Modulation) technology and MPEG2 / MPEG4 digital compression mapping technology to achieve high-quality, low-latency data transmission. COFDM technology is particularly suitable for transmitting data in multi-path and strong interference environments, while MPEG2 / MPEG4 technology effectively reduces the bandwidth requirements during data transmission, ensuring transmission efficiency while reducing the risk of data loss.

[0088] Another embodiment of the communication system for tethered UAV for power infrastructure in the embodiment of the present invention includes: the communication module includes a warning module, an anti-interference module, an information transmission module, a backup communication module, and a communication rate adjustment module;

[0089] The warning module is used to issue an alarm when the drone exceeds a predetermined communication range;

[0090] The anti-interference module is used to divide the bandwidth into multiple sub-channels through COFDM technology, and transmit the environmental image data of the power infrastructure after data compression, the environmental sound data of the power infrastructure after data compression, and the monitoring data after data compression to multiple sub-channels respectively, and each sub-channel adopts orthogonal frequency division multiplexing technology;

[0091] The information transmission module is used to transmit the encrypted environmental image data in the power infrastructure, the encrypted environmental sound data in the power infrastructure and the monitoring data to the ground control center through MPEG2 / MPEG4 digital compression mapping technology;

[0092] The backup communication module is used to perform backup communication transmission when communication fails to ensure the continuity of communication;

[0093] The communication rate adjustment module is used to automatically adjust the communication rate under different environments to optimize data transmission.

[0094] Specifically, the communication module is explained in detail:

[0095] Alert module:

[0096] Function: The warning module issues an alarm before the drone is likely to exceed the predetermined communication range. This is a preventive measure to notify the operator in advance that the drone is about to leave the effective control range, so that corresponding measures can be taken, such as adjusting the flight path or enhancing the communication signal, to ensure that the drone does not lose contact.

[0097] Anti-interference module:

[0098] Function: The anti-interference module uses COFDM technology to divide the entire bandwidth into many independent sub-channels, and uses orthogonal frequency division multiplexing technology on each sub-channel. This method can greatly reduce signal interference and achieve more stable and reliable data transmission. In drone operations that need to traverse complex environments such as power infrastructure inspections, this module ensures that the data collected by the drone can be transmitted back to the ground control center without loss and accurately.

[0099] Information transmission module:

[0100] Function: The information transmission module is responsible for transmitting the encrypted environmental image data, encrypted environmental sound data and monitoring data in the power infrastructure through MPEG2 / MPEG4 digital compression mapping technology. This technology not only improves the transmission efficiency by reducing the size of data, but also reduces the risk of delay and loss during data transmission, ensuring the integrity and timeliness of information.

[0101] Spare communication module:

[0102] Function: The backup communication module provides a backup communication channel when the main communication link fails. The design of this module takes into account the unexpected situations that the communication system may encounter, such as signal interference or equipment failure, to ensure the continuity of information transmission and stable control of the drone.

[0103] Communication rate adjustment module:

[0104] Function: The communication rate adjustment module is responsible for automatically adjusting the communication rate according to different environmental conditions. This adaptive adjustment mechanism can optimize the data transmission speed according to the real-time network status and data volume, reduce network congestion and data transmission delay, and ensure the efficiency and stability of communication.

[0105] In the embodiment of the present invention, the communication modules work together to form a complex but efficient communication system, which ensures that the important information obtained by the UAV in tasks such as power infrastructure inspection can be safely, reliably and efficiently transmitted to the ground control center. The design of these modules takes into account the various situations that the UAV may encounter in actual operation, thereby ensuring the stability and reliability of the entire communication system and meeting the high-standard industrial application requirements.

[0106] Another embodiment of the power infrastructure tethered drone communication system in the embodiment of the present invention includes: the information processing module includes an information collection module and an encryption module;

[0107] The information collection module is used to collect environmental image data and environmental sound data in the power infrastructure;

[0108] The encryption module is used to perform secure encryption processing on the environmental image data and the environmental sound data in the electric power infrastructure to obtain the encrypted environmental image data and the encrypted environmental sound data in the electric power infrastructure.

[0109] Specifically, the information processing module includes an information collection module and an encryption module; the information collection module is the component in the drone communication system that is responsible for directly interacting with the environment. It uses sensors installed on the drone, such as cameras and microphones, to collect image and sound data of the surrounding environment. These data are crucial for performing tasks such as power infrastructure inspections and terrain mapping, as they provide real-time, intuitive environmental information that can be used for subsequent analysis and decision-making.

[0110] The information acquisition module is usually equipped with a high-resolution camera and a high-sensitivity microphone to ensure high-quality image and sound data. In addition, the module can work stably under various environmental conditions, including in low-light or high-noise environments.

[0111] Encryption module:

[0112] Function: Before the information is transmitted back to the ground control center, the encryption module securely encrypts the collected environmental image data and environmental sound data in the power infrastructure. This step is very critical because it protects the security of the data during transmission and prevents sensitive information from being intercepted and used by unauthorized third parties. The encrypted environmental image data and environmental sound data in the power infrastructure can be transmitted securely. Even if they are intercepted during transmission, the data is difficult to interpret due to encryption.

[0113] The encryption module uses powerful encryption technologies, such as symmetric encryption algorithms (such as AES) or asymmetric encryption algorithms (such as RSA), to ensure the confidentiality and integrity of data. These encryption technologies can not only protect data from unauthorized access, but also verify the source of the data to ensure that the received information has not been tampered with.

[0114] In the embodiment of the present invention, the beneficial effect is that the information processing module is an important part of the UAV communication system. Through the close cooperation of the information collection module and the encryption module, the environmental information can be effectively collected and ensured to be safely transmitted back to the ground control center. The information collection module provides high-quality direct environmental information, while the encryption module ensures the security of this information during transmission. The entire information processing process is both efficient and safe, providing reliable data support for the UAV to perform complex tasks.

[0115] Another embodiment of the power infrastructure tethered drone communication system in the embodiment of the present invention includes: the encryption module is specifically used for:

[0116] Collecting the identification code of the drone; wherein the identification code is a unique identifier of the drone;

[0117] According to the identification code, the corresponding drone information is retrieved in the security database; wherein the drone information at least includes drone operator information, drone bound device information, and drone merchant information;

[0118] According to the drone information, searching for an information screening algorithm matching the drone information in a security database; wherein the security database pre-stores a corresponding relationship between the drone information and the information screening algorithm, and the information screening algorithm is used to ensure the uniqueness and confidentiality of each information screening algorithm;

[0119] According to the device information bound to the drone, the standard character mapping map is personalized to form a target character mapping map for the device information bound to the drone;

[0120] Extract key feature terms from environmental image data and environmental sound data in the power infrastructure to obtain pinyin information of the terms, find a digital mapping relationship corresponding to the pinyin information of the terms in a security database, and convert the pinyin information of the terms into digital information based on the digital mapping relationship;

[0121] Using the generated target character mapping atlas, character mapping is performed on the converted digital information, and the character mapping value is output;

[0122] Select characters from the character mapping value according to the matched information screening algorithm, and combine the characters according to a predetermined combination method to form an encryption key;

[0123] The environmental image data in the electric power infrastructure and the environmental sound data in the electric power infrastructure are encrypted based on the encryption key.

[0124] Specific, important term explanation:

[0125] Identification code: A drone’s unique identifier, used to distinguish between different drones.

[0126] Safety database: A database that pre-stores various information (including drone information and information screening algorithms and their corresponding relationships) to support the safe operation of the system.

[0127] Information screening algorithm: An algorithm used to generate encryption keys based on the specific information of the drone to ensure the uniqueness and confidentiality of each generated encryption key.

[0128] Character Map: A rule or template for converting specific digital information into character information, which is used to generate encryption keys.

[0129] Application scenarios:

[0130] This technical solution is applicable to the fields of power infrastructure monitoring and inspection. By using drones equipped with advanced encryption modules, efficient and safe monitoring of infrastructure can be achieved. The system collects environmental image data and environmental sound data in power infrastructure in real time and ensures the secure transmission of data, and has the ability to continuously monitor key facilities.

[0131] The technical solution is further explained:

[0132] In this embodiment, when the drone performs the power infrastructure inspection task, it first collects the drone's own identification code through its encryption module. Then, according to the identification code, it retrieves and obtains the corresponding drone information in the security database, including operator information, bound device information and merchant information. Next, according to this information, it searches the database for matching information screening algorithms.

[0133] The standard character mapping map is personalized according to the device information bound to the drone to form a target character mapping map for the device. At the same time, key feature entries are extracted from the collected environmental image and sound data, the entry pinyin information is obtained, and the corresponding digital mapping relationship is found. Based on this relationship, the entry pinyin information is converted into digital information, and the target character mapping map is used to map the digital information into characters.

[0134] Finally, characters are selected from the character mapping value according to the matched information screening algorithm, and these characters are combined in a predetermined combination to form an encryption key. The encryption key is used to encrypt the environmental image data and environmental sound data in the power infrastructure to ensure their security during transmission.

[0135] Furthermore, the encryption module also implements the step of personalizing the standard character mapping map according to the device information bound to the drone to form a target character mapping map for the device information bound to the drone, which can be refined into the following specific steps:

[0136] 1. Identify the device information bound to the drone

[0137] First, it is necessary to identify the specific devices bound to the drone, including but not limited to sensor types (such as temperature sensors, optical sensors, etc.), camera specifications (such as resolution, focal length, etc.), and microphone types. The technical parameters and characteristics of each device will provide the basis for the personalized arrangement of the character map.

[0138] 2. Collect standard character maps

[0139] Collect standard character mapping maps, which usually contain a set of predefined mapping rules from numbers to characters. The mapping rules define how digital information should be converted into character information, providing a template and reference for subsequent personalized editing.

[0140] 3. Analyze device characteristics

[0141] Analyze the identified device characteristics and determine the data characteristics and transmission requirements of each device. For example, image data generated by a high-resolution camera requires more detailed mapping rules to maintain data details, while data from a specific sensor only requires simple mapping rules.

[0142] 4. Design target character map

[0143] Based on the results of the device characteristic analysis, the standard character mapping map is personalized and arranged to form a target character mapping map for the drone-bound device. This includes adjusting the mapping rules from numbers to characters, introducing new mapping rules to meet the data characteristics of specific devices, or deleting mapping rules that are not applicable to the device.

[0144] Based on the results of device characteristic analysis, the specific steps for implementing personalized adjustment and arrangement of the standard character mapping map can be further detailed as follows:

[0145] 1. Define standard character map

[0146] First, we need to define a standard character mapping map. This map is used as a basis and contains a set of basic rules for converting numbers to characters. For example, we can map the numbers 0-9 to the AJ characters in the basic character set.

[0147] 2. Analyze device data requirements

[0148] Conduct in-depth analysis of the data type and processing requirements of each device on the drone. For example, if the drone is equipped with a high-resolution camera, more detailed correspondence needs to be considered in the character mapping process to ensure the information richness and accuracy of the image data during the conversion process; if it is a temperature sensor, more attention is paid to the accurate mapping of the numerical value rather than the richness of details.

[0149] 3. Adjust mapping rules

[0150] According to the analysis results, the standard character mapping map is adjusted, including adding new mapping rules, such as introducing a mixture of uppercase letters, lowercase letters and special characters for specific types of data to increase the density and complexity of the encoding, or adjusting the existing mapping rules to meet the needs of specific devices.

[0151] 4. Introducing device-specific mapping sequences

[0152] Create or specify a specific mapping sequence for each device type. This can be achieved by sorting or reorganizing the character set to reflect the characteristics of the device. For example, a device may be more sensitive to numbers, and number-related characters can be prepended in the mapping to optimize data processing and encryption quality.

[0153] 5. Design a multi-dimensional mapping strategy

[0154] For some complex devices, it is necessary to design a multi-dimensional mapping strategy to simultaneously process and map multiple data from different sensors. This requires implementing hierarchical or parallel mapping rules in the target character mapping map to ensure the comprehensiveness and accuracy of data encryption.

[0155] 6. Performance evaluation and optimization

[0156] Through simulation or actual data encryption tests, the performance of the newly compiled target character mapping graph is evaluated, including encryption speed, data restoration accuracy and security, etc. Based on the test results, necessary optimization is carried out to ensure the practicality of the graph.

[0157] 7. Document and apply

[0158] Finally, the adjusted and optimized target character mapping map is documented, and the mapping rules and strategies corresponding to each device are recorded in detail. It is then implemented in the encryption module for the secure encryption processing of environmental image data and environmental sound data in power infrastructure.

[0159] The technical solution is further explained:

[0160] The process of extracting key feature terms from the environmental image data and environmental sound data in the power infrastructure and converting the phonetic information of these terms into digital information can be divided into the following steps:

[0161] 1. Data Preprocessing

[0162] Environmental image data in power infrastructure:

[0163] Noise reduction: Use image processing techniques, such as Gaussian blur or median filtering, to remove image noise.

[0164] Enhancement processing: Adjust image contrast and brightness to improve image quality so as to better recognize text or logos in the image.

[0165] Environmental sound data in power infrastructure:

[0166] Noise reduction processing: Use noise suppression algorithm to reduce background noise and extract clear speech signals.

[0167] Format conversion: Convert raw sound data into a format suitable for processing and analysis, such as WAV.

[0168] 2. Feature term extraction

[0169] Environmental image data in power infrastructure:

[0170] Text recognition: Apply optical character recognition (OCR) technology to identify text content from processed images.

[0171] Term screening: Extract key words from the recognized text through natural language processing (NLP) technology.

[0172] Environmental sound data in power infrastructure:

[0173] Speech-to-text: Use speech recognition technology to convert sound data into text.

[0174] Term screening: Also using NLP technology, key words are extracted from the transcribed text.

[0175] 3. Pinyin conversion

[0176] Use a pinyin conversion tool or library, such as a Chinese pinyin conversion tool, to convert the extracted keywords into pinyin form. The purpose of this step is to unify the representation of text information for subsequent processing.

[0177] 4. Digital twin

[0178] A pinyin to number mapping table is preset in the security database. The table contains mapping rules from a single pinyin or pinyin combination to numbers. For example, "bai" can be mapped to "01", "shi" can be mapped to "02", and so on. The mapping rules should be designed in advance and saved in the security database.

[0179] 5. Convert to digital information

[0180] The pinyin information of each entry is converted into corresponding digital information according to the mapping table in the security database. This step involves converting each pinyin according to the mapping table. If an entry contains multiple pinyins, each pinyin will be converted in turn and concatenated into a string of digital information.

[0181] 6. Verification and Storage

[0182] Finally, the converted digital information is verified to ensure the accuracy of the conversion process, and then the digital information is stored or further encrypted.

[0183] To implement the specific mapping table design and application process from pinyin to numbers, you can follow the detailed steps below:

[0184] 1. Build a pinyin library

[0185] First, we need to create a library that covers all possible pinyins for Chinese. This library should contain the pinyins of single syllables (such as "bai", "shi", etc.), and can consider the changes in the pinyin tones (such as "bai1", "bai2", etc., representing different tones) to adapt to the pinyin information of different entries.

[0186] 2. Define mapping rules

[0187] Define a unique numeric code for each pinyin. This process should ensure that each pinyin is mapped to a unique numeric combination to avoid duplication and conflict. For example:

[0188] "bai" is mapped to "01"

[0189] "shi" is mapped to "02"

[0190] The length of the digital code here should be determined according to actual needs, maintaining a certain degree of flexibility and scalability.

[0191] 3. Create a digital map

[0192] Create a numeric mapping table in the secure database. This table should store each pinyin and its corresponding numeric code in the form of key-value pairs. For example, one record in the table might be {"bai": "01"} and another record might be {"shi": "02"}.

[0193] 4. Design mapping algorithm

[0194] Design an algorithm to automatically match the extracted pinyin information of the entry with the records in the mapping table to achieve automatic conversion from pinyin to numbers. The basic process of the algorithm is as follows:

[0195] Input: Pinyin information of one or more extracted terms.

[0196] deal with:

[0197] Split the pinyin of each word into individual syllables.

[0198] For each syllable's pinyin, look up the corresponding digital code in the digital mapping table.

[0199] If an entry contains multiple pinyin, the numeric codes corresponding to these pinyin are concatenated in order to form a long numeric string.

[0200] Output: converted digital information.

[0201] 5. Automated processing

[0202] The above mapping algorithm can be implemented by programming, and any programming language that supports database operations and string processing can be used, such as Python, Java, etc. The code should include the access logic to the security database and the core algorithm for processing and converting pinyin information.

[0203] In the embodiment of the present invention, the beneficial effect is: the technical solution realizes a highly personalized and secure data encryption method by introducing the concepts of identification code, security database, information screening algorithm and target character mapping atlas. In this way, even if the data is illegally intercepted during the data transmission process, the data that cannot be decrypted cannot be used, thereby greatly enhancing the information security of the drone when performing power infrastructure monitoring and inspection tasks. Furthermore, this encryption method also improves the reliability of data transmission, provides technical support for the efficient operation and maintenance of power infrastructure, and helps to realize remote and unmanned monitoring and management.

[0207] Apply the optimized character mapping rules to rearrange the standard character mapping map to generate a target character mapping map corresponding to the device information bound to the drone; wherein the target character mapping map will serve as a basis for generating an encryption key to ensure that the generation process of the encryption key depends on the device information bound to the drone.

[0215] Further explanation of the technical solution:

[0216] Collect information about devices bound to the drone: The system first identifies and records information about all devices bound to the drone, including the type, function, and usage environment of each device.

[0217] Extract corresponding character mapping rules: According to the device information, relevant character mapping rules are retrieved from the security database. These rules are pre-customized for different functional characteristics of drones, so they can reflect the specific needs of the device.

[0218] Adjust and optimize mapping rules: According to the actual usage scenarios of the drone, such as high-altitude flight, extreme climatic conditions, etc., make necessary adjustments and optimizations to the retrieved character mapping rules to adapt to the specific operating environment.

[0219] Generate target character mapping map: Apply optimized mapping rules to rearrange the standard character mapping map to form a new set of target character mapping maps for drone equipment information. This map will directly affect the generation of encryption keys to ensure the uniqueness and security of the keys.

[0220] Further refinement of the technical solution:

[0221] Adjusting and optimizing the mapping rules to adapt to the actual use scenarios of drones, such as high-altitude flight and extreme weather conditions, involves multiple specific implementation steps. The following describes the specific implementation methods in a step-by-step manner:

[0222] 1. Analyze usage scenario characteristics

[0223] First, the system needs to conduct a comprehensive analysis of the drone’s operating environment and mission requirements. This includes but is not limited to:

[0230] Optimize data compression mapping rules to meet the data storage and transmission efficiency requirements during long-term flights.

[0231] In low temperature environments, the mapping rules are adjusted to reduce the load of the data processing process on the device battery.

[0232] 3. Design adjustment plan

[0233] Design specific adjustment plans for the identified adjustment points. This may involve:

[0234] Increase redundant mapping: Design redundant mapping for critical data to enhance data integrity in harsh environments.

[0235] Dynamic mapping adjustment: Dynamically adjust mapping rules based on real-time environmental data, such as automatically switching to a higher-intensity encryption mode when signal interference increases.

[0236] Preset variables for mapping rules: Introduce environment-dependent variables (such as temperature and altitude) as part of the mapping rules so that the mapping rules can be adaptively adjusted based on these variables.

[0237] 4. Implementation adjustments and optimization

[0238] The above adjustment scheme is implemented through programming. The environment perception module, data processing module and dynamic mapping rule adjustment module are integrated into the drone software to ensure that in different usage scenarios, the drone can automatically adjust the character mapping rules according to the predefined logic and real-time environmental data.

[0239] In the embodiment of the present invention, the beneficial effects are as follows: by binding device information to generate a personalized character mapping map, it is ensured that the generated encryption key has a high degree of relevance and unpredictability, thereby enhancing the security of the data transmission process. By analyzing and responding to the characteristics of different usage scenarios, the target character mapping map formed can specifically improve the data protection capability of the drone system in a specific environment, ensuring that the data is protected from malicious attacks and illegal interception during transmission. This technical solution allows the character mapping rules to be flexibly adjusted and optimized according to the changes in the device information bound to the drone and the usage scenarios, thereby providing the drone system with higher adaptability and operational reliability.

[0255] Further explanation of the technical solution:

[0256] Generation and storage of drone identification codes:

[0257] When the drone is initialized, the system generates a unique identification code and enters this identification code into a preset data table together with the drone's operator information, bound device information, and drone merchant information.

[0258] This data table is also designed to support fast retrieval by introducing an effective indexing mechanism to optimize query performance.

[0259] Optimization and encryption of data tables:
