Description

Technical Field

[0001] The present invention relates to the field of autonomous driving in mining areas, and specifically to a system and method for safely dispatching unmanned mining vehicles based on discrete variable quantum key distribution. Background Art

[0002] With the rapid development of computer science and technology, especially artificial intelligence (AI), the widespread adoption and application of 5G communications, and the continued breakthroughs in quantum technology, we are entering an unprecedented era of technological explosion. This wave of technology has not only dramatically changed our lifestyles but also brought unprecedented challenges and development opportunities to the manufacturing sector, especially the mining industry.

[0003] Unmanned mining trucks, a landmark achievement of the emerging technological revolution, are leading a profound transformation in the mining industry. These highly intelligent trucks integrate advanced technologies such as high-precision positioning and navigation, environmental perception and obstacle avoidance, and path planning. They receive real-time dispatch instructions from a dispatch center, enabling precise operation in complex and ever-changing mining environments, significantly improving the safety and efficiency of mining operations.

[0004] However, the widespread use of driverless mining vehicles also poses new challenges to the system's information security. In intelligent mining operations, driverless mining vehicles frequently exchange information with the dispatch center. This critical information includes vehicle status, operating instructions, and environmental data. The security and integrity of this information is directly related to the stable operation and efficiency of the entire mining operation, and particularly the safety of other personnel involved. While traditional encryption algorithms such as RSA, based on the principle of large number factorization, still play an important role in ensuring information security, their security is facing severe challenges with the rapid development of advanced technologies such as quantum computing.

[0005] Once the encryption algorithm is cracked, sensitive data will be leaked. In particular, if the dispatching center's control instructions to the mine car are illegally obtained or tampered with, it may cause serious production accidents and even have a catastrophic impact on the mining area and the surrounding environment. Summary of the Invention

[0009] The vehicle-side data processing and control module receives environmental information of the area where the mining vehicle is located, and performs data fusion, preprocessing and storage;

[0010] The vehicle-side quantum key management service module is used to store, distribute, and destroy quantum keys, as well as use quantum keys to decrypt scheduling decision instructions from the scheduling center subsystem and encrypt the environmental information of the mining car area in the vehicle-side data processing and control module;

[0011] The vehicle-side network communication module is used to receive information from the dispatch center subsystem and send information to the dispatch center subsystem;

[0012] The dispatch center subsystem includes a dispatch end quantum key receiving device module, a dispatch end quantum key management service module, a dispatch end data processing and decision center module, and a dispatch end network communication module;

[0013] The dispatch end quantum key receiving device module is used to receive the unmanned mining car subsystem's unmanned mining car subsystem

[0014] The dispatching end data processing and decision center module generates a dispatching decision instruction based on the environmental information of the area where the mine car is located;

[0015] The dispatch-side quantum key management service module is used to store, distribute, and destroy quantum keys, and use quantum keys to encrypt dispatch decision instructions from the dispatch-side data processing and decision-making center module, and decrypt environmental information about the mine car area from the unmanned mine car subsystem;

[0016] The dispatching end network communication module is used to receive information from the unmanned mine car subsystem and send information to the unmanned mine car subsystem.

[0017] Furthermore, the vehicle-side quantum key generation device module includes a vehicle-side quantum random number generator, an optical quantum transmitter and a vehicle-side quantum communication unit;

[0018] The vehicle-side quantum random number generator uses the principles of quantum mechanics to generate a binary true random number sequence and transmits it to the optical quantum transmitter;

[0019] The optical quantum transmitter prepares the binary true random number sequence into a quantum state and transmits it to the dispatching center subsystem through the vehicle-side quantum communication unit.

[0020] Furthermore, the scheduling-end quantum key receiving device module includes a scheduling-end quantum random number generator, an optical quantum receiver and a scheduling-end quantum communication unit;

[0021] The scheduling end quantum random number generator uses the principles of quantum mechanics to generate a binary true random number sequence as a measurement basis sequence;

[0022] The optical quantum receiver receives a quantum state binary true random number sequence from the unmanned mining vehicle subsystem, and selects two groups of measurement bases from the measurement base sequence to measure the quantum state binary true random number sequence;

[0023] The scheduling end quantum communication unit performs quantum communication with the vehicle end quantum communication unit;

[0024] Furthermore, the dispatching-end data processing and decision-making center module uses artificial intelligence algorithms to process environmental information of the area where the mine car is located, conducts a comprehensive assessment of the operating efficiency, energy consumption, and environmental impact of the unmanned mine car, and generates dispatching decision instructions.

[0025] Furthermore, the scheduling decision instructions include travel routes, optimized mining strategies, and operation sequences between different mining vehicles.

[0026] Furthermore, the vehicle-side data processing and control module performs data preprocessing steps including:

[0027] s1) Remove high-frequency noise or random fluctuations from data through filtering algorithms or signal processing techniques; identify and process outliers in data using statistical methods or machine learning algorithms;

[0028] s2) calibrating the sensor using preset standard values ​​or reference data;

[0029] s3) remove redundant information from the data;

[0030] s4) Verify the integrity of the data to ensure that the data is not damaged or lost during transmission.

[0031] Furthermore, the vehicle-side quantum communication unit corresponds to the scheduling-side quantum communication unit, and uses a free-space quantum channel to transmit quantum state information.

[0032] Furthermore, the unmanned mining vehicle obtains environmental information of the area where the mining vehicle is located through GPS, IMU, radar and cameras;

[0033] The environmental information of the area where the mine car is located includes the mine car location information, the precise location of the workers in the production environment, the information of the surrounding mine cars, the distribution of mineral resources and the road conditions.

[0034] A method based on the unmanned mining car safety dispatching system comprises the following steps:

[0035] 1) The unmanned mining vehicle obtains environmental information of the area where the mining vehicle is located and transmits it to the vehicle-side data processing and control module;

[0036] 2) The vehicle-side data processing and control module performs data fusion, preprocessing and storage on the environmental information of the area where the mining vehicle is located;

[0037] 3) The unmanned mining vehicle calls the vehicle-side quantum random number generator built into the vehicle-side quantum key generation device module, uses the principles of quantum mechanics to generate a binary true random number sequence, and sends it to the optical quantum transmitter;

[0038] The optical quantum transmitter prepares the binary true random number sequence into a quantum state and sends it to the optical quantum receiver in the quantum key receiving device module at the dispatch end through the vehicle-end quantum communication unit;

[0039] 4) The optical quantum receiver measures the binary true random number sequence of the quantum state. After the measurement, the unmanned mining vehicle subsystem and the dispatch center subsystem conduct key negotiation to generate a securely shared quantum key, which is stored in the vehicle-side quantum key management service module and the dispatch-side quantum key management service module respectively;

[0040] 5) The vehicle-side data processing and control module calls the vehicle-side quantum key management service module, encrypts the data information, and sends it to the dispatch-side data processing and decision center module through the vehicle-side network communication module;

[0041] 6) The data processing and decision center module receives and processes the data uploaded by the vehicle-side data processing and control module, generates scheduling decision instructions, and calls the scheduling-side quantum key management service module to encrypt the scheduling decision instructions and send them to the vehicle-side data processing and control module through the scheduling-side network communication module;

[0042] 7) After receiving the encrypted scheduling decision instructions, the vehicle-side data processing and control module calls the vehicle-side quantum key management service module to decrypt them, obtain the scheduling instructions, and control the driving direction, speed and operation mode of the unmanned mining car.

[0043] Furthermore, in step 4), the step of generating a securely shared quantum key includes:

[0044] 4.1) The vehicle-side quantum random number generator generates a binary true random number sequence;

[0045] The optical quantum transmitter prepares two non-orthogonal quantum states based on the polarization state of the photon, denoted as |+> and |1>, which correspond to 0 and 1 in the binary true random number sequence respectively;

[0046] For each photon, the optical quantum transmitter selects one of the states according to the binary true random number sequence and sends it to the optical quantum receiver in the quantum key receiving device module at the scheduling end through the vehicle-end quantum communication unit.

[0047] 4.2) The optical quantum receiver selects two base pairs, {|0>, |1>} or {|+>, |->}, based on the binary true random number sequence generated by the quantum random number generator at the dispatching end to measure each received photon. The two base pairs correspond to 0 and 1 in the random number sequence, respectively.

[0048] If |0> or |-> is measured, the positions of these photons are recorded and recorded as valid bits. If |+> or |1> is measured, the corresponding photons are deleted. For each valid bit, if |0> is measured, it means that the optical quantum transmitter sent |+>, which corresponds to 0 in the key; if |-> is measured, it means that the optical quantum transmitter sent |1>, which corresponds to 1 in the key.

[0049] 4.3) After the measurement is completed by the dispatch-side quantum key receiving device module, the measurement results are transmitted to the vehicle-side quantum key generation device module through the dispatch-side quantum communication unit;

[0050] 4.4) The unmanned mining car subsystem and the dispatch center subsystem perform key negotiation to generate a securely shared quantum key.

[0051] Further, in step 4.1), the polarization state of the photon includes a horizontal polarization state, a vertical polarization state, a 45-degree polarization state, and a 135-degree polarization state;

[0052] The horizontal polarization state is recorded as |0>, the vertical polarization state is recorded as |1>, the 45-degree polarization state is recorded as |+>, and the 135-degree polarization state is recorded as | Denoted as |->;

[0053] Among them, the horizontal polarization state |0> and the vertical polarization state |1> form a set of orthogonal bases, called Z basis; the 45-degree polarization state |+> and the 135-degree polarization state |-> form a set of orthogonal bases, called X basis;

[0054] The two states in each basis are mutually orthogonal, and the projections of any basis vector in one basis onto any basis vector in the other basis are equal.

[0055] The technical benefits of this invention are undeniable. It is based on specific quantum mechanical principles and properties, such as quantum superposition, wave function collapse, quantum entanglement, the Heisenberg uncertainty principle, and the quantum no-cloning theorem. This means that any attempt to copy or measure a quantum state inevitably destroys its original state, enabling the precise detection of eavesdroppers. Upon detecting eavesdropping, the current communication is interrupted and a new one reestablished until an eavesdrop-free communication process is complete. This allows for the secure exchange of keys between the communicating parties, ensuring the absolute security of key distribution. This invention applies discrete variable quantum key distribution technology to the communication process between unmanned mining vehicles and a dispatch center, allowing both parties to share a highly secure quantum key for encrypting and decrypting all transmitted data and information. Compared to traditional encryption methods that rely on mathematical computational complexity for confidentiality, the quantum key distribution protocol offers superior security and confidentiality, effectively preventing data and information from being eavesdropped, tampered with, or forged during transmission, ensuring the integrity and security of communications and enabling more secure command and dispatch.

[0161] 4.2) The optical quantum receiver selects two base pairs, {|0>, |1>} or {|+>, |->}, based on the binary true random number sequence generated by the quantum random number generator at the dispatching end to measure each received photon. The two base pairs correspond to 0 and 1 in the random number sequence, respectively.

[0162] If |0> or |-> is measured, the positions of these photons are recorded and recorded as valid bits. If |+> or |1> is measured, the corresponding photons are deleted. For each valid bit, if |0> is measured, it means that the optical quantum transmitter sent |+>, which corresponds to 0 in the key; if |-> is measured, it means that the optical quantum transmitter sent |1>, which corresponds to 1 in the key.

[0163] 4.3) After the measurement is completed by the dispatch-side quantum key receiving device module, the measurement results are transmitted to the vehicle-side quantum key generation device module through the dispatch-side quantum communication unit;

[0164] 4.4) The unmanned mining car subsystem and the dispatch center subsystem perform key negotiation to generate a securely shared quantum key.

[0167] The horizontal polarization state is recorded as |0>, the vertical polarization state is recorded as |1>, the 45-degree polarization state is recorded as |+>, and the 135-degree polarization state is recorded as | Denoted as |->;

[0168] Among them, the horizontal polarization state |0> and the vertical polarization state |1> form a set of orthogonal bases, called Z basis; the 45-degree polarization state |+> and the 135-degree polarization state |-> form a set of orthogonal bases, called X basis;

[0169] The two states in each basis are mutually orthogonal, and the projections of any basis vector in one basis onto any basis vector in the other basis are equal.

[0170] Example 14:

[0171] A driverless mine car safety dispatching system based on discrete variable quantum key distribution includes two subsystems: an driverless mine car subsystem for information exchange and a dispatching center subsystem.

[0172] The unmanned mining car subsystem includes: a vehicle-side quantum key generation device module for generating quantum keys, a vehicle-side quantum key management service module for unified management of quantum keys and encryption and decryption of information data, a vehicle-side data processing and control module for data preprocessing and controlling various operations of the unmanned mining car, and a vehicle-side network communication module for classical communication.

[0173] The vehicle-side quantum key generation device module includes a vehicle-side quantum random number generator for generating a string of binary true random number sequences, an optical quantum transmitter for preparing quantum states, and a vehicle-side quantum communication unit for performing quantum communication.

[0174] The dispatch center subsystem includes: a dispatch-side quantum key receiving device module for generating quantum keys, a dispatch-side quantum key management service module for unified management of quantum keys and encryption and decryption of information data, a dispatch-side data processing and decision center module for deep data processing and generating optimal decision-making dispatch instructions, and a dispatch-side network communication module for classical communication.

[0175] The scheduling-end quantum key receiving device module includes a scheduling-end quantum random number generator for generating another string of binary true random number sequences, an optical quantum receiver for measuring quantum states, and a scheduling-end quantum communication unit for performing quantum communication.

[0176] The vehicle-side quantum communication unit corresponds to the dispatch-side quantum communication unit and is responsible for transmitting quantum states using quantum channels. The vehicle-side quantum key management service module corresponds to the dispatch-side quantum key management service module and is responsible for unified management of quantum keys, including distribution, storage, and destruction, as well as encryption and decryption of information data. The vehicle-side network communication module corresponds to the dispatch-side network communication module and is responsible for transmitting data information using classical channels.

[0177] Example 15:

[0178] A method for safe scheduling of unmanned mining vehicles based on discrete variable quantum key distribution includes the following four steps: data collection step, quantum key generation step, decision scheduling step and instruction execution step.

[0179] In the data collection step, the unmanned mining car collects surrounding environmental information through sensors such as GPS, IMU, radar and cameras, including the location information of the mining car, the precise location of workers in the production environment, information about surrounding mining cars, mineral resource distribution and road conditions, and sends the collected information data to the vehicle-side data processing and control module for data fusion, preprocessing and storage.

[0180] In the data collection step, when the unmanned mining vehicle is started, all sensors are activated, continuously monitor the surrounding environment, and transmit data information in real time to ensure real-time and integrity.

[0181] During the quantum key generation step, the unmanned mining vehicle uses the on-board quantum random number generator (QRG) built into the vehicle-side quantum key generation module. Using the principles of quantum mechanics, it generates a binary true random number sequence as the basis for preparing the quantum state. This sequence is then sent to the optical quantum transmitter. The transmitter then generates the quantum state based on this sequence and transmits it via the vehicle-side quantum communication module to the optical quantum receiver in the dispatcher-side quantum key receiving module for measurement. After all measurements are complete, both parties negotiate a key via a classical channel, generate a quantum key, and store it in their respective quantum key management service modules.

[0182] In the quantum key generation step, the optical quantum transmitter uses the four polarization states of photons for encoding. These four polarization states are horizontal polarization state → recorded as |0>, vertical polarization state↑ recorded as |1>, 45 degree polarization state Denoted as |+> and 135 degrees polarization state Denoted as |->. The horizontal polarization state |0> and the vertical polarization state |1> form an orthogonal basis, called the Z basis; the 45-degree polarization state |+> and the 135-degree polarization state |-> form an orthogonal basis, called the X basis. The two states within each basis are orthogonal, and the projections of any basis vector in one basis onto any basis vector in the other are equal. Non-orthogonal states cannot be fully distinguished through measurement. This quantum property enhances key security.

[0183] The specific description of the quantum key generation is as follows:

[0184] The vehicle-side quantum random number generator generates a binary sequence of length N and sends it to the optical quantum transmitter. Based on this sequence, the optical quantum transmitter generates two non-orthogonal quantum states: bit 0 corresponds to the 45-degree polarization state |+>, and bit 1 corresponds to the vertical polarization state |1>. These are then sent to the optical quantum receiver in the quantum key receiving device module on the dispatch side. The optical quantum receiver uses another binary random number sequence generated by the dispatch side quantum random number generator to select one of two bases: the Z basis {|0>, |1>} or the X basis {|+>, |->}. Each received photon is measured using either the Z basis (bit 0) or the X basis (bit 1).

[0185] If the dispatcher measures |1> or |+>, these results are discarded and not recorded or used for subsequent key generation. If the dispatcher measures |0> or |1>, these quantum states are retained. This is because if the vehicle transmits a |+> quantum state and the dispatcher measures it using the Z basis, quantum mechanics suggests it could measure either |0> or |1>, with a 50% probability. If the measurement result is |1>, the dispatcher cannot determine which quantum state the vehicle transmitted, because if the vehicle transmits |1>, the dispatcher will also measure |1>. However, if the dispatcher measures |0> using the Z basis and the result is |0>, it can be determined that the optical quantum transmitter transmitted |+>. The positions of these photons are recorded and called valid bits. Similarly, if the vehicle transmits a |1> quantum state and the dispatcher measures it using the X basis, quantum mechanics suggests it could measure either |+> or |->, with a 50% probability. If the measurement result is |+>, the dispatcher cannot determine which quantum state the vehicle transmitted, because if the vehicle transmits |+>, the dispatcher will also measure |+>. However, when the dispatcher measures using the X basis and obtains a result of |->, it can be determined that the optical quantum transmitter transmitted |->. The positions of these photons are recorded and called valid bits. A valid bit represents a data point that the vehicle and dispatcher can use to construct a shared key. For each valid bit, if the dispatcher measures |0>, it indicates that the vehicle's quantum key generation module transmitted |+>, which is considered a 0 in the key. If the dispatcher measures |->, it indicates that the vehicle's quantum key generation module transmitted |1>, which is considered a 1 in the key.

[0186] After all measurements are complete, the dispatcher's quantum key receiving module transmits the results via a classical channel back to the vehicle's quantum key generation module. Both ends negotiate a key and, after applying classical coding error correction and key amplification techniques, generate a securely shared quantum key. Subsequently, both ends send the quantum key via a classical channel to their respective quantum key management service modules, which then store the quantum key.

[0187] In the decision-making and scheduling step, the vehicle-side data processing and control module calls the vehicle-side quantum key management service module, encrypts the data information and sends it to the scheduling-side data processing and decision center module through the vehicle-side network communication module. The data processing and decision center module receives and processes various types of data uploaded by the vehicle-side data processing and control module, and makes the optimal scheduling decision instructions through a mathematical optimization algorithm based on reinforcement learning. It then calls the scheduling-side quantum key management service module to encrypt the instructions and sends them to the vehicle-side data processing and control module through the scheduling-side network communication module.

[0188] The data processing and decision-making center module has powerful data processing capabilities and can seamlessly connect with the massive data uploaded from the vehicle-side data processing and control module. It can perform efficient data cleaning, conversion and integration processes on the received data to ensure the accuracy, completeness and consistency of the data, laying a solid foundation for subsequent decision-making analysis.

[0189] The data processing and decision-making center module relies on advanced artificial intelligence algorithms such as deep learning and reinforcement learning to achieve intelligent decision-making in complex scenarios, generate optimal scheduling decision instructions, and ensure the scientificity and rationality of decision instructions.

[0190] In order to ensure the secure transmission of dispatch instructions, the data processing and decision-making center module again calls the dispatch-side quantum key management service module to encrypt the instructions. The encrypted instructions are then securely and reliably sent to the vehicle-side data processing and control module through the dispatch-side network communication module.

[0191] During the instruction execution step, the vehicle-side data processing and control module receives the encrypted dispatch decision instruction and then calls the vehicle-side quantum key management service module to decrypt the instruction using the quantum key. Based on the decoded instruction, the driverless mining vehicle's direction, speed, and operating mode are controlled, ensuring safe and efficient operation according to the instructions.

[0192] Encryption and decryption are performed using a quantum key in a "one-time, one-pad" manner. After this step, the quantum key management service module destroys the quantum key and waits for the next quantum key to be generated.

[0193] Example 16:

[0194] The unmanned mine car safety dispatching system based on discrete variable quantum key distribution includes an unmanned mine car subsystem and a dispatching center subsystem for data communication and information interaction.

[0195] The unmanned mining vehicle subsystem includes a vehicle-side quantum key generation device module, a vehicle-side quantum key management service module, a vehicle-side data processing and control module, and a vehicle-side network communication module. The dispatch center subsystem includes a dispatch-side quantum key reception device module, a dispatch-side quantum key management service module, a dispatch-side data processing and decision center module, and a dispatch-side network communication module.

[0196] The vehicle-side quantum key generation device module and the scheduling-side quantum key receiving device module generate a quantum key shared by both parties based on the discrete variable quantum key distribution protocol, and send it to the vehicle-side quantum key management service module for unified management of the quantum key to ensure the security of subsequent data transmission.

[0197] The vehicle-side quantum key management service module mainly manages the generated quantum keys in a unified manner, including key storage and key distribution according to the needs of other modules, as well as encryption and decryption operations on information data and decision-making instructions.

[0198] The vehicle-side data processing and control module is the core module of the unmanned mining car. It is responsible for compressing and pre-processing the raw data collected by the mining car sensors, including position, speed, posture, surrounding environment and operation information, and storing the extracted useful information. It is also responsible for receiving decision instructions from the dispatching center and controlling various operations of the mining car, including navigation, excavation and loading.

[0199] The vehicle-side network communication module communicates with the dispatch-side network communication module through classic channels, and is responsible for transmitting collected information data and receiving decision instructions from the dispatch center, such as conducting regular network communications with the dispatch center or other mining vehicles.

[0200] The scheduling-end quantum key receiving device module and the vehicle-end quantum key generation device module generate a quantum key shared by both parties based on the discrete variable quantum key distribution protocol, and send it to the scheduling quantum key management service module for unified management of the quantum key.

[0201] The quantum key management service module at the scheduling end mainly manages the generated quantum keys in a unified manner, including key storage and key distribution according to the needs of other modules, as well as encryption and decryption operations on information data and decision instructions.

[0202] The data processing and decision-making center module on the dispatch side serves as the core hub of the entire system. Relying on its powerful computing capabilities and advanced big data analysis technology, it conducts in-depth mining and rapid processing of the massive amounts of data uploaded by the vehicle-side data processing and control module. Subsequently, through complex artificial intelligence algorithms such as deep learning and reinforcement learning, a comprehensive assessment of the unmanned mining vehicles' operating efficiency, energy consumption, and environmental impact is conducted on multiple dimensions. Based on the comprehensive assessment results, the data processing and decision-making center module on the dispatch side implements intelligent decision-making in complex scenarios and formulates optimal dispatch decision instructions, including adjusting the mining vehicle's safety-first route, optimizing mining strategies, and coordinating the operating sequence between different vehicles. The goal is to achieve efficient unmanned mining vehicle operations and rational resource allocation.

[0203] The dispatching-side network communication module communicates with the vehicle-side network communication module through classic channels. It is responsible for transmitting the decision-making instructions of the dispatching center and receiving information data collected from the vehicle side, such as conducting regular network communications with mining cars or other dispatching centers.

[0204] like Figure 1As shown, the vehicle-side quantum key generation device module also includes a vehicle-side quantum random number generator, an optical quantum transmitter and a vehicle-side quantum communication unit.

[0205] The vehicle-side quantum random number generator module uses the principles of quantum mechanics to generate a binary true random number sequence and uses it as the basis for quantum state preparation.

[0206] The optical quantum transmitter prepares the quantum state based on the binary true random number sequence generated by the quantum random number generator.

[0207] The vehicle-side quantum communication unit communicates with the scheduling-side quantum communication unit through a quantum channel and is responsible for transmitting the prepared quantum state.

[0208] like Figure 1 As shown, the scheduling-end quantum key receiving device module also includes a scheduling-end quantum random number generator, an optical quantum receiver and a scheduling-end quantum communication unit.

[0209] The quantum random number generator at the scheduling end uses the principles of quantum mechanics to generate a binary true random number sequence and uses it as the basis for selecting the measurement basis.

[0210] The optical quantum receiver receives the quantum state sent by the optical quantum transmitter based on the binary true random number sequence generated by the quantum random number generator, and measures the quantum state.

[0211] The quantum communication unit at the dispatching end communicates with the quantum communication unit at the vehicle end through a quantum channel and is responsible for transmitting the prepared quantum state.

[0212] like Figure 1 As shown in the figure, the vehicle-side quantum communication unit corresponds to the dispatch-side quantum communication unit and is responsible for transmitting quantum states using free-space quantum channels (such as optical fiber links, free-space links, etc.). The vehicle-side quantum key management service module corresponds to the dispatch-side quantum key management service module and is responsible for unified management of quantum keys, including distribution, storage, and destruction, as well as encryption and decryption of information data. The vehicle-side network communication module corresponds to the dispatch-side network communication module and is responsible for transmitting data information using classical channels.

[0213] like Figure 1 As shown, the vehicle-side quantum key management service module and the vehicle-side data processing and control module communicate with the dispatching center through the vehicle-side network communication module; the dispatching-side quantum key management service module and the dispatching-side data processing and decision center module communicate with the unmanned mining car through the dispatching-side network communication module.

[0214] like Figure 1 As shown, the quantum key management service module sends the quantum key to the corresponding module only when the module requests encryption or decryption.

[0215] like Figure 2 As shown, the present invention also provides a method for safe scheduling of unmanned mining vehicles based on discrete variable quantum key distribution, which includes a data collection step, a quantum key generation step, a decision scheduling step, and an instruction execution step, as shown below:

[0216] In the data collection step, the unmanned mining vehicle collects different aspects of environmental information through sensors such as GPS, IMU, radar and camera, and sends it to the vehicle-side data processing and control module for data fusion, preprocessing and storage.

[0217] During the data collection step, GPS provides high-precision geographic location information for the mine cart, including longitude, latitude, and altitude. The IMU measures the cart's motion, including acceleration, angular velocity, and direction. Radar transmits and receives radio waves to detect obstacles and terrain around the cart, providing distance and speed information for obstacle avoidance and collision prevention. The camera captures images of the cart's surroundings, identifying road signs and other carts, providing visual perception capabilities.

[0218] In the data collection step, when the unmanned mine car is started, all sensors are activated and continuously monitor the surrounding environment to collect information including the mine car location information, the precise location of workers in the production environment, information about surrounding mine cars, mineral resource distribution, and road conditions. The collected data information is sent to the vehicle-side data processing and control module for efficient data cleaning, removing noise and outliers in the sensor data and improving data quality; through data correction, the deviation and error of the sensor are reduced to ensure the accuracy of the data; through data compression, the data is compressed to reduce the burden of storage and transmission and ensure the real-time and integrity of data transmission.

[0219] like Figure 3 、 Figure 4 As shown, in the quantum key generation step, the vehicle-side quantum random number generator in the vehicle-side quantum key generation device module generates a binary true random number sequence of length N, recorded as sequence A (as shown below, a binary true random number sequence with N=10):

[0220] (0,1,1,0,0,1,1,0,0,1)

[0221] Using this as the basis for preparing quantum states, the optical quantum transmitter generates two non-orthogonal quantum states for each photon according to this sequence. These are then transmitted via the vehicle-side quantum communication module to the optical quantum receiver in the dispatcher-side quantum key receiving device module. Bit 0 corresponds to the 45-degree polarization state |+>, and bit 1 corresponds to the vertical polarization state |1>, resulting in the following quantum states:

[0222] (|+>,|1>,|1>,|+>,|+>,|1>,|1>,|+>,|+>,|1>)

[0223] The quantum random number generator on the scheduling end generates another binary random number sequence of length N, denoted as sequence B (as shown below, a binary true random number sequence with N=10):

[0224] (0,1,0,0,0,0,1,1,0,1)

[0225] Based on this sequence, the optical quantum receiver selects two bases, Z basis {|0>, |1>} or X basis {|+>, |->}, to randomly measure each received photon. Bit 0 selects Z basis measurement, and bit 1 selects X basis measurement. The measurement basis selection is:

[0226] (Z,X,Z,Z,Z,Z,X,X,Z,X)

[0227] Random measurements are intended to prevent any potential eavesdropper from predicting or controlling the choice of the measurement basis, thereby ensuring the security of communications.

[0228] According to the principles of quantum mechanics, if the vehicle sends |+> and the dispatcher measures using the X basis, it will definitely measure |+>; if the dispatcher measures using the Z basis, it may measure |0> or |1>. If |1> is measured, the dispatcher is unsure which state the vehicle sent; if |0> is measured, the dispatcher can be sure that the vehicle sent |+>. Similarly, according to the principles of quantum mechanics, if the vehicle sends |1> and the dispatcher measures using the Z basis, it will definitely get |1>; if the dispatcher measures using the X basis, it may get |+> or |->. If |+> is measured, the dispatcher is unsure which state the vehicle sent; if |-> is measured, the dispatcher can be sure that the vehicle sent |1>. Therefore, the following set of measurement results are obtained:

[0229] (|0>,|->,|1>,|0>,|1>,|1>,|->,|+>,|0>,|+>)

[0230] according to Figure 4 The flowchart first determines whether the measurement result is |0> or |->. If not, the quantum state is discarded; if so, it is retained and the next step is taken. If the dispatcher measures |0>, it means that the vehicle-side quantum key generation module sent |+>, which is considered a 0 in the key; if the dispatcher measures |->, it means that the vehicle-side quantum key generation module sent |1>, which is considered a 1 in the key. Therefore, the retained sequence is:

[0231] (0,1,0,1,0)

[0232] After all measurements are completed, the dispatcher's quantum key receiving device module transmits the above results to the vehicle-side quantum key generation module via the classical channel, and randomly selects some bits for public comparison to detect eavesdropping. If the bit error rate is less than the previously set threshold, error correction is performed; if the bit error rate is greater than the threshold, eavesdropping is considered to have occurred and the protocol is terminated. The two parties negotiate a key and generate a securely shared quantum key after classical error correction and key amplification:

[0233] (0,1,1,0)

[0234] Afterwards, the quantum key is sent to the respective quantum key management service module through the classical channel, and the quantum key management service module stores the quantum key.

[0235] During the decision-making and scheduling steps, the vehicle-side data processing and control module invokes the vehicle-side quantum key management service module, encrypts the data using the quantum key, and then transmits it via the vehicle-side network communication module to the dispatcher-side data processing and decision-making center module. As the core hub of the entire system, the data processing and decision-making center module leverages its powerful computing capabilities and advanced big data analysis techniques to deeply mine and rapidly process the massive amounts of data uploaded by the vehicle-side data processing and control module. Through efficient data cleaning, conversion, and integration processes, it extracts valuable information for decision-making. This information covers multiple aspects, including the mining vehicle's operating efficiency, energy consumption patterns, and the impact of the operation on the surrounding environment. This ensures the accuracy, completeness, and consistency of the data, laying a solid foundation for subsequent decision-making analysis.

[0236] Subsequently, intelligent algorithms based on deep neural networks and reinforcement learning conduct a comprehensive assessment of the autonomous mining vehicles' operating efficiency, energy consumption, and environmental impact. Based on this assessment, the system formulates optimal scheduling decisions. These decisions include adjusting the vehicles' routes to reduce unnecessary travel distance and energy consumption; optimizing mining strategies to maximize the amount and quality of ore mined; and coordinating the operating sequence between different vehicles to avoid operational conflicts and resource waste. These decisions are generated by fully considering real-time road conditions, the status of the mining vehicles, and external environmental factors to ensure scientific and rational decision-making.

[0237] After the scheduling decision instructions are formulated, in order to ensure that the scheduling decision instructions can be safely and accurately conveyed to the unmanned mining car, the data processing and decision center module also calls the scheduling-side quantum key management service module to encrypt the instructions, ensuring the confidentiality and integrity of the instruction transmission. The encrypted instructions are then sent back to the vehicle-side data processing and control module through the scheduling-side network communication module.

[0238] During the instruction execution step, after receiving the encrypted dispatch decision instruction, the vehicle-side data processing and control module again calls the vehicle-side quantum key management service module to decrypt the instruction using the previously shared quantum key. Based on the parsed dispatch instruction, the vehicle-side data processing and control module then precisely controls the unmanned mining vehicle, ensuring safe and efficient operation according to the dispatch instruction. The completion of this series of steps closes the entire process, and the quantum key management service module destroys the quantum key and waits for the next quantum key generation.

For each valid bit, if |0> is measured, it means that the optical quantum transmitter sent |+>, which corresponds to 0 in the key; if |-> is measured, it means that the optical quantum transmitter sent |1>, which corresponds to 1 in the key. 4.3) After the measurement is completed by the dispatch-side quantum key receiving device module, the measurement results are transmitted to the vehicle-side quantum key generation device module through the dispatch-side quantum communication unit; 4.4) The unmanned mining car subsystem and the dispatch center subsystem perform key negotiation to generate a securely shared quantum key.

10. The method according to claim 9, characterized in that In step 4.1), the polarization states of the photons include horizontal polarization state, vertical polarization state, 45 degree polarization state and 135 degree polarization state; The horizontal polarization state is recorded as |0>, the vertical polarization state is recorded as |1>, the 45-degree polarization state is recorded as |+>, and the 135-degree polarization state is recorded as | Denoted as |->; Among them, the horizontal polarization state |0> and the vertical polarization state |1> form a set of orthogonal bases, called Z basis; the 45-degree polarization state |+> and the 135-degree polarization state |-> form a set of orthogonal bases, called X basis; The two states in each basis are mutually orthogonal, and the projections of any basis vector in one basis onto any basis vector in the other basis are equal.
