Description

Technical Field

[0001] The present invention relates to the field of autonomous driving in mining areas, and in particular 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 technology, the widespread popularization and application of 5G communication technology, and the continuous breakthroughs in quantum technology, we are entering an unprecedented era of technological explosion. This wave of technology has not only greatly changed people's lifestyles, but also brought unprecedented challenges and development opportunities to the manufacturing field, especially the mining industry.

[0003] As one of the landmark achievements of the emerging scientific and technological revolution, unmanned mining vehicles are leading the profound transformation of the mining industry. Highly intelligent unmanned mining vehicles integrate advanced technologies such as high-precision positioning and navigation, environmental perception and obstacle avoidance, and path planning. They can receive dispatch instructions from the dispatch center in real time and achieve precise operations in complex and changeable mining environments, thereby greatly improving the safety and work efficiency of mining operations.

[0004] However, the widespread use of driverless mining vehicles has also posed new challenges to the information security of the system. In the intelligent mining operation system, driverless mining vehicles frequently exchange information with the dispatch center. These vital information include mining vehicle status, operation instructions, and environmental data. The security and integrity of information are directly related to the stable operation and efficiency of the entire mining operation, especially the life safety of other personnel involved in the operation. At present, although traditional encryption algorithms such as RSA based on the principle of large number decomposition still play an important role in ensuring information security, with the rapid development of advanced technologies such as quantum computing, its security is facing severe challenges.

[0005] Once the encryption algorithm is cracked, sensitive data will be leaked. In particular, if the dispatch 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 surrounding environment. Summary of the invention

[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 according to the environmental information of the area where the mine car is located;

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

[0017] Further, 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 generates a binary true random number sequence using the principles of quantum mechanics 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] Further, 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 generates a binary true random number sequence as a measurement base sequence using the principle of quantum mechanics;

[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 dispatching 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 operating 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 in data through filtering algorithms or signal processing techniques; use statistical methods or machine learning algorithms to identify and process outliers in data;

[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-end quantum communication unit corresponds to the scheduling-end quantum communication unit, and uses a free-space quantum channel to transmit quantum state information.

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

[0033] The environmental information of the area where the mine car is located includes the location information of the mine car, 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 car obtains the environmental information of the area where the mining car 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 mine car is located;

[0037] 3) The unmanned mining car 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 car subsystem and the dispatch center subsystem negotiate the key, generate a secure shared quantum key, and store it 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-making 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 a dispatch decision instruction, and calls the dispatch-side quantum key management service module to encrypt the dispatch decision instruction and send it to the vehicle-side data processing and control module through the dispatch-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, obtain the scheduling instructions, and control the driving direction, speed and operation mode of the unmanned mining car.

[0043] Further, 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 sets of bases {|0>, |1>} or {|+>, |->} according to the binary true random number sequence generated by the quantum random number generator at the scheduling end to measure each received photon. The two sets of bases 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 photon transmitter sent |+>, which corresponds to 0 in the key; if |-> is measured, it means that the photon transmitter sent |1>, which corresponds to 1 in the key.

[0049] 4.3) After the measurement of the quantum key receiving device module at the dispatching end is completed, the measurement result is transmitted to the quantum key generating device module at the vehicle end through the quantum communication unit at the dispatching end;

[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> constitute a set of orthogonal bases, called Z basis; the 45-degree polarization state |+> and the 135-degree polarization state |-> constitute 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 effect of the present invention is unquestionable. The present invention is based on specific quantum mechanical principles and characteristics: such as quantum superposition, wave function collapse, quantum entanglement, Heisenberg uncertainty principle and quantum no-cloning theorem, that is, any attempt to copy or measure the quantum state will inevitably destroy its original state, so that the existence of the eavesdropper can be discovered without omission. When the communication is found to be eavesdropped, the current communication is interrupted and a new communication is rebuilt until a communication process without eavesdropping is completed, so that the keys can be exchanged safely between the two parties in communication, and this mechanism is used to ensure the absolute security of key distribution. The present invention applies discrete variable quantum key distribution technology to the communication process between the unmanned mining car and the dispatching center, which means that both parties can share a highly secure quantum key for encrypting and decrypting all transmitted data information. Compared with the traditional encryption method based on the complexity of mathematical calculations for confidentiality, the quantum key distribution protocol has higher security and confidentiality, can effectively prevent data information from being eavesdropped, tampered with or forged during transmission, ensure the integrity and security of communication, and thus achieve safer command and dispatch.

[0177] Embodiment 15:

[0178] A method for safe dispatching of unmanned mining vehicles based on discrete variable quantum key distribution includes the following four steps: a data collection step, a quantum key generation step, a decision-making and dispatching step, and an 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 camera, including the location information of the mining car, the precise location of the staff in the production environment, the information of the surrounding mining cars, the distribution of mineral resources 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] In the quantum key generation step, the unmanned mining car 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 as the basis for preparing the quantum state, and sends the sequence to the optical quantum transmitter. The optical quantum transmitter prepares the quantum state according to the sequence and sends it to the optical quantum receiver in the scheduling-side quantum key receiving device module through the vehicle-side quantum communication module for measurement. After all measurements are completed, the two parties negotiate the key through the classical channel, generate the 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 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 |->. 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 orthogonal to each other, and the projections of any basis vector in one basis on any basis vector in another basis are equal. Non-orthogonal states cannot be completely distinguished by measurement. This quantum property improves the security of the key.

[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. The optical quantum transmitter prepares two non-orthogonal quantum states based on the sequence, bit 0 corresponds to the 45-degree polarization state |+>, and bit 1 corresponds to the vertical polarization state |1>, and sends them to the optical quantum receiver in the quantum key receiving device module at the scheduling end. The optical quantum receiver selects one of the two bases, Z basis {|0>, |1>} or X basis {|+>, |->}, through another binary random number sequence generated by the quantum random number generator at the scheduling end to measure each received photon. Bit 0 represents measurement with Z basis, and bit 1 represents measurement with X basis.

[0185] If the dispatcher measures |1> or |+>, these result data are discarded, and they will not be recorded or used for subsequent key generation. If the dispatcher measures |0> or |1>, these quantum states are retained. The reason for this is as follows: If the vehicle transmits the |+> quantum state, the dispatcher uses the Z basis to measure. According to the principles of quantum mechanics, the dispatcher may measure |0> or |1>, and the probability of both is 50%. If the measurement result is |1>, the dispatcher cannot determine which quantum state the vehicle sent, because if the vehicle sends |1>, the dispatcher will also measure |1>. When the dispatcher uses the Z basis to measure and the result is |0>, it can be determined that the optical quantum transmitter sent |+>, and the positions of these photons are recorded and called valid bits. Similarly, if the vehicle transmits the |1> quantum state, the dispatcher uses the X basis to measure. According to the principles of quantum mechanics, the dispatcher may measure |+> or |->, and the probability of both is 50%. If the measurement result is |+>, the dispatcher cannot determine which quantum state the vehicle sent, because if the vehicle sends |+>, the dispatcher will also get |+>. When the dispatcher uses the X basis to measure and the result is |->, it can be determined that the optical quantum transmitter sent |->, and the positions of these photons are recorded and called valid bits. The valid bits represent data points that the vehicle and the dispatcher can use to build a shared key. For each valid bit, if the dispatcher measures |0>, it means that the vehicle quantum key generation module sent |+>, which is regarded as 0 in the key; if the dispatcher measures |->, it means that the vehicle quantum key generation module sent |1>, which is regarded as 1 in the key.

[0186] After all measurements are completed, the dispatch end quantum key receiving device module sends the measurement results back to the vehicle end quantum key generation module through the classical channel. The two ends negotiate the key and generate a secure shared quantum key after using the classical coding error correction technology and key amplification technology. Subsequently, the two ends send the quantum key to their respective quantum key management service modules through the classical channel, and the quantum key management service module stores 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 to 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 securely and reliably sent to the vehicle-side data processing and control module through the dispatch-side network communication module.

[0191] In the instruction execution step, after receiving the encrypted scheduling decision instruction, the vehicle-side data processing and control module calls the vehicle-side quantum key management service module again to obtain the scheduling instruction after decrypting the quantum key. According to the parsed instruction, the driving direction, speed and operation mode of the unmanned mining car are controlled to ensure that the mining car runs safely and efficiently according to the instruction.

[0192] Encryption and decryption are performed using quantum keys 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] Embodiment 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.

The dispatch center subsystem includes the dispatch-side quantum key receiving device module, the dispatch-side quantum key management service module, the dispatch-side data processing and decision center module, and the 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 is mainly responsible for the unified management of the generated quantum keys, 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 mine car. It is responsible for compressing and preprocessing the raw data collected by the mine car sensors, including position, speed, posture, surrounding environment and operation information, and storing it after extracting useful information.

[0199] The vehicle-side network communication module communicates with the dispatch-side network communication module through classic channels, and is responsible for transmitting the 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 generating 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 is mainly responsible for the unified management of the generated quantum keys, including the storage of keys and the distribution of keys according to the needs of other modules, as well as the encryption and decryption of information data and decision instructions.

[0202] As the core hub of the entire system, the data processing and decision-making center module on the dispatch side relies on its powerful computing power and advanced big data analysis technology to conduct in-depth mining and rapid processing of the massive 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 evaluation of the operating efficiency, energy consumption, and environmental impact of the unmanned mining car is conducted. Based on the comprehensive evaluation results, the data processing and decision-making center module on the dispatch side realizes intelligent decision-making in complex scenarios and formulates the optimal dispatch decision instructions, including adjusting the mine car's safety-first route, optimizing mining strategies, and coordinating the operating sequence between different vehicles, etc., aiming to achieve high efficiency of unmanned mining car operations and reasonable allocation of resources.

[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 quantum states based on a binary true random number sequence generated by a 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 scheduling 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, 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 dispatching 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] In the data collection step, GPS provides high-precision geographic location information of the mine car, including longitude, latitude, and altitude. IMU measures the motion state of the mine car, including acceleration, angular velocity, and direction. Radar detects obstacles and terrain around the mine car by transmitting and receiving radio waves, and provides distance and speed information for obstacle avoidance and collision prevention. The camera captures images around the mine car, which are used to identify road signs and other mine cars, etc., providing visual perception capabilities for the mine car.

[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 location information of the mine car, the precise location of the staff in the production environment, information of the surrounding mine cars, the distribution of mineral resources and road conditions, and 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 of N=10):

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

[0221] It is used as the basis for preparing quantum states. For each photon, the optical quantum transmitter prepares two non-orthogonal quantum states according to the sequence, and sends them to the optical quantum receiver in the quantum key receiving device module at the dispatch end through the vehicle-side quantum communication module. Bit 0 corresponds to the 45-degree polarization state |+>, and bit 1 corresponds to the vertical polarization state |1>, so the following quantum states are prepared:

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

[0223] The quantum random number generator at 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 of N=10):

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

[0225] The optical quantum receiver selects two groups of bases, Z basis {|0>, |1>} or X basis {|+>, |->}, according to the sequence to perform random measurement on 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 it using the X basis, it will definitely get |+>; if the dispatcher measures it using the Z basis, it may get |0> or |1>. If |1> is measured, the dispatcher is not sure 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 it using the Z basis, it will definitely get |1>; if the dispatcher measures it using the X basis, it may get |+> or |->. If |+> is measured, the dispatcher is not sure 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, the quantum state is retained and the next step is performed. If the dispatch end measures |0>, it means that the vehicle-side quantum key generation module sends |+>, which is regarded as 0 in the key; if the dispatch end measures |->, it means that the vehicle-side quantum key generation module sends |1>, which is regarded as 1 in the key. Therefore, the retained sequence is:

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

[0232] After all measurements are completed, the dispatch-side quantum key receiving device module informs the vehicle-side quantum key generation module of the above results through the classical channel, and randomly selects some bits for public comparison for eavesdropping detection. 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, it is considered that eavesdropping exists and the protocol is terminated. The two parties negotiate the 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] In the decision-making and scheduling step, the vehicle-side data processing and control module calls the vehicle-side quantum key management service module, uses the quantum key to encrypt the data information, and then sends it to the data processing and decision center module on the scheduling side through the vehicle-side network communication module. As the core hub of the entire system, the data processing and decision center module relies on its powerful computing power and advanced big data analysis technology to conduct in-depth mining and rapid processing of the massive data uploaded by the vehicle-side data processing and control module, and extracts valuable information for decision-making through efficient data cleaning, conversion and integration processes. This information covers multiple aspects such as the operating efficiency of the mining car, energy consumption patterns, and the impact of the operating process on the surrounding environment, ensuring the accuracy, completeness and consistency of the data, and laying a solid foundation for subsequent decision-making analysis.

[0236] Subsequently, the intelligent algorithm based on deep neural network and reinforcement learning comprehensively evaluates the operating efficiency, energy consumption and environmental impact of unmanned mining vehicles, and formulates the optimal scheduling decision instructions based on this, including adjusting the route of mining vehicles to reduce unnecessary driving distance and energy consumption; optimizing mining strategies to maximize the mining volume and quality of ore; coordinating the operation sequence between different vehicles to avoid operation conflicts and resource waste, etc. The generation of instructions fully considers the real-time road conditions, mining vehicle status and external environmental factors to ensure the scientificity and rationality of 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-end 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-end data processing and control module through the scheduling-end network communication module.

[0238] In the instruction execution step, after receiving the encrypted scheduling decision instruction, the vehicle-side data processing and control module will call the vehicle-side quantum key management service module again and use the previously shared quantum key to decrypt the instruction. According to the parsed scheduling instruction, the vehicle-side data processing and control module will then accurately control the unmanned mining car to ensure that the mining car runs safely and efficiently according to the scheduling instruction. The completion of this series of steps marks the closed loop of the entire process. The quantum key management service module destroys the quantum key and waits for the next quantum key to be generated.

The method according to claim 8, characterized in that In step 4), the step of generating a securely shared quantum key includes: 4.1) The vehicle-side quantum random number generator generates a binary true random number sequence; 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; 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 dispatching end through the vehicle-end quantum communication unit; 4.2) The optical quantum receiver selects two sets of bases {|0>, |1>} or {|+>, |->} according to the binary true random number sequence generated by the quantum random number generator at the scheduling end to measure each received photon. The two sets of bases correspond to 0 and 1 in the random number sequence respectively; 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 photon transmitter sent |+>, which corresponds to 0 in the key; if |-> is measured, it means that the photon transmitter sent |1>, which corresponds to 1 in the key. 4.3) After the measurement of the quantum key receiving device module at the dispatching end is completed, the measurement result is transmitted to the quantum key generating device module at the vehicle end through the quantum communication unit at the dispatching end; 4.4) The unmanned mining car subsystem and the dispatch center subsystem perform key negotiation to generate a securely shared quantum key.
