Description

Technical Field

[0001] The present invention relates to a data transmission system, and particularly to a data transmission system between Internet of Things devices based on quantum communication technology applied to the field of quantum communication. Background Art

[0002] Quantum secure communication is a secure communication technology formed by combining QKD (Quantum Key Distribution) with other cryptographic technologies. As a typical application of quantum communication, QKD realizes the generation and distribution of keys by transmitting quantum states. When the communicating parties distribute keys through QKD, any eavesdropping behavior will be detected in a timely manner due to the perturbation of the quantum state. As a key distribution component in cryptography, QKD can be combined with various encryption and authentication technologies to form quantum secure communication schemes with different security requirements.

[0003] Carbon neutrality refers to the total amount of carbon dioxide or greenhouse gas emissions directly or indirectly generated by an enterprise, product, activity or individual within a certain period of time. Through forms such as afforestation and energy conservation and emission reduction, the carbon dioxide or greenhouse gas emissions generated by itself are offset to achieve a positive and negative offset and reach relative "zero emissions". For enterprises, carbon emissions mainly come from production, office work, transportation, and the upstream and downstream transportation of products. Therefore, in order to achieve the goal of carbon neutrality, it is usually necessary to detect and collect carbon emission data in the above scenarios and summarize it through the network to the processing terminal for processing. Once data leakage occurs during the above data transmission process, it is easy to cause the leakage of enterprise production, office work, and employees' personal information.

[0004] The specification of invention patent 202411555314.8 discloses a method and device for real-time code generation of free-space quantum key distribution. The method includes a sending end sending an optical quantum stream and a laser signal to a receiving end, the receiving end detecting the received optical quantum stream to obtain a quantum raw detection signal, generating a plurality of raw key information data packets according to the synchronous coding information and measurement basis vectors in the received laser signal and sending the plurality of raw key information data packets to the sending end through a laser communication channel, the sending end obtaining basis comparison key data and information according to the modulation basis vector and the measurement basis vectors in the plurality of raw key information data packets, processing the basis comparison key data by using a low-density parity-check code to obtain check data and generating a plurality of intermediate key information data packets, and sending the plurality of intermediate key information data packets to the receiving end, and the receiving end obtaining the check data from the received plurality of intermediate key information data packets and processing the check data to obtain a target quantum key.

[0005] With the development of carbon neutralization technology, the data demand for carbon emissions generated by enterprises in the processes of production, office work, transportation, and upstream and downstream transportation of products is even greater. At the same time, the accuracy and real-time nature of the data need to be maintained. However, the security of traditional data transmission methods is relatively low. Summary of the Invention

[0006] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is that the security of traditional data transmission methods is relatively low.

[0007] To solve the above problems, the present invention provides a data transmission system between Internet of Things devices based on quantum communication technology, including a key distribution center. The key distribution center is signal-connected to a quantum key update device and a user terminal. The quantum key update device is signal-connected to a quantum key storage medium. The quantum key storage medium is signal-connected to a mobile terminal. An encrypted connection is achieved between the mobile terminal and the user terminal through the Internet; The mobile terminal includes a vehicle and a monitoring module. The monitoring module includes a base installed on the vehicle's central control display screen. The base includes a mounting part. One end of the mounting part close to the central control display screen is fixedly connected to a connecting part. A connecting glue layer is fixedly connected between the connecting part and the central control display screen. A plurality of monitoring holes are drilled in the mounting part. A vibration detection unit and a temperature detection unit are respectively inserted into the plurality of monitoring holes. One end of the mounting part away from the monitoring holes is fixedly connected to an identification module.

[0008] In the above-mentioned data transmission system between Internet of Things devices based on quantum communication technology, the protection of information interaction in the carbon neutralization system is achieved through quantum communication technology, and the enterprise production information and personal information are effectively protected.

[0009] Preferably, during the driving process of the vehicle, continuous vibrations will be generated. When the vibration sensor continuously detects vibration data for 3 minutes, the vehicle running time detection will continue until the vibration sensor does not detect vibration data for 1 minute continuously. If the continuous vibration time is less than 3 minutes, it is regarded as a false detection. The vehicle state will be changed from driving to stationary, and the accumulated vehicle running time will be subtracted.

[0010] Preferably, the vibration detection unit includes a housing. At one end of the housing close to the base, a detection cavity is drilled. A sealing cover is threadedly connected to the opening of the detection cavity. A vibration sensor is slidably connected in the detection cavity. A connector is fixedly connected to the sealing cover, and both ends of the connector penetrate through the sealing cover and are respectively located on both sides inside and outside the detection cavity. A connecting wire is fixedly connected between the vibration sensor and the connector, and a magnetic shielding layer is coated on the outer wall of the connecting wire. One end of the sealing cover and the vibration sensor close to each other are respectively fixedly connected with an electromagnetic ring and a magnetic ring that are matched in position. A compression spring is fixedly connected between the sealing cover and the vibration sensor. When the vehicle starts or parks for a long time, the cooperation of the electromagnetic ring and the compression spring can be used to regularly detect the working state of the vibration sensor to ensure the working state of the vibration detection unit.

[0011] Preferably, an identification mark is drilled at one end of the housing away from the base, which is used to identify the vibration detection unit and the temperature detection unit, facilitating maintenance and replacement work.

[0012] Preferably, a dust-proof plug is inserted into the spare monitoring hole, leaving enough preparatory structure for subsequent module expansion work.

[0013] Preferably, a plurality of safety holes are drilled in the installation part, and the positions of the safety holes are matched with the monitoring holes. Anti-disengagement units are fixedly connected to the vibration detection unit, the temperature detection unit, and the dust-proof plug. The anti-disengagement unit includes fixing nails inserted into the safety holes. A connecting cable is fixedly connected between the plurality of fixing nails and the vibration detection unit, the temperature detection unit, and the dust-proof plug respectively. By using the anchoring effect of the anti-disengagement unit, the risk of secondary injury to the driver and other passengers caused by the vibration detection unit, the temperature detection unit, and the dust-proof plug flying out can be reduced.

[0014] Preferably, a plurality of positioning rings are fixedly connected to the inner wall of the safety hole, and a plurality of anti-disengagement skirts are fixedly connected to the side wall of the fixing nail. The anti-disengagement skirts are made of elastic materials. The spacing distances of the plurality of anti-disengagement skirts are the same, and the distance between adjacent positioning rings increases as the distance between the positioning ring and the connecting cable decreases. When the vibration detection unit, the temperature detection unit, and the dust-proof plug fly and pull the anti-disengagement unit, the collision between the plurality of positioning rings and the anti-disengagement skirts and the fracture of the anti-disengagement skirts are used to reduce the flying speed of the vibration detection unit, the temperature detection unit, and the dust-proof plug and reduce their harm.

[0015] Preferably, a separation groove is drilled in each of the plurality of anti-disengagement skirts. When the anti-disengagement skirt breaks, fragments will be formed, which is convenient for cleaning the broken anti-disengagement skirt from the safety hole and facilitating the replacement work of the vibration detection unit, the temperature detection unit, and the dust-proof plug.

[0016] In summary, in the present application, the symmetric quantum key pairs generated by the key distribution center are respectively pre-set in the quantum security service key distribution center and the quantum key update device close to the user. When the mobile terminal user accesses for the first time or the key is exhausted, a certain amount of keys can be injected through the quantum key update device and pre-set in the secure storage medium of the mobile terminal for authentication and session encryption in its subsequent communication process.

[0017] When the mobile terminal communicates with the user terminal, identity authentication is completed through the key distribution center using part of the quantum keys stored in the mobile terminal. Then, the key distribution center negotiates a session key between the mobile terminal and the user terminal to generate a one-time use session key, and the session information is encrypted and decrypted by combining OTP or other symmetric key encryption algorithms.

[0018] The information interaction protection of the carbon neutralization system is realized through quantum communication technology, effectively protecting enterprise production information and personal information. Taking the vibration generated during the vehicle's driving process as the detection object, the vehicle startup time is judged, and the current vehicle's carbon dioxide emission is determined. Compared with the data filled in manually in the traditional method, the detection data of this method is more accurate, and at the same time, the data is automatically generated without the need for employees to fill it in separately, improving the data collection efficiency. When the vehicle starts or stops for a long time, the cooperation of the electromagnetic ring and the compression spring can be used to regularly detect the working state of the vibration sensor to ensure the working state of the vibration detection unit.

[0019] Finally, the vibration detection unit, the temperature detection unit, and the dustproof plug are fixed on the base using the anti-disconnection unit. When the vehicle encounters a traffic accident, a strong impact will occur, and there is a risk that the vibration detection unit, the temperature detection unit, and the dustproof plug will break away from the installation part. Using the anchoring effect of the anti-disconnection unit, the risk of secondary injury to the driver and other passengers caused by the vibration detection unit, the temperature detection unit, and the dustproof plug flying out can be reduced.

Specific embodiments

[0022] The following will make a detailed description of the two embodiments of the present application with reference to the accompanying drawings.

[0023] The first embodiment: Figure 1 A data transmission system between Internet of Things devices based on quantum communication technology is shown, including a key distribution center. The key distribution center is signal - connected to a quantum key update device and a user terminal. The quantum key update device is signal - connected to a quantum key storage medium. The quantum key storage medium is signal - connected to a mobile terminal. An encrypted connection is achieved between the mobile terminal and the user terminal through the Internet; The symmetric quantum key pairs generated by the key distribution center are respectively pre - set in the key distribution center of the quantum security service and the quantum key update device close to the user. When a mobile terminal user first accesses or the key is exhausted, a certain amount of keys can be refilled through the quantum key update device and pre - set in the secure storage medium (such as a smart password key, a security chip, etc.) of the mobile terminal for authentication and session encryption in its subsequent communication process.

[0024] When the mobile terminal communicates with the user terminal, identity authentication is completed through a partial quantum key stored in the mobile terminal via a key distribution center. Then, the key distribution center is used to negotiate a session key between the mobile terminal and the user terminal to generate a one-time session key, and the session information is encrypted and decrypted using OTP (One Time Pad) or other symmetric key encryption algorithms.

[0025] Please refer to Figure 2 , on the above basis, taking the data transmission system for corporate carbon neutrality as an example, the mobile terminal includes a vehicle and a monitoring module.

[0026] Please refer to Figures 3 - 5 , the monitoring module includes a base 2 installed on the vehicle central control display screen 1. The base 2 includes a mounting portion 201. One end of the mounting portion 201 close to the central control display screen 1 is fixedly connected with a connecting portion 202. A connecting glue layer 203 is fixedly connected between the connecting portion 202 and the central control display screen 1. A plurality of monitoring holes 204 are drilled in the mounting portion 201. A vibration detection unit 3 and a temperature detection unit 4 are respectively inserted into the plurality of monitoring holes 204. One end of the mounting portion 201 far from the monitoring holes 204 is fixedly connected with an identification module 207; Please refer to Figures 7 - 8 , the vibration detection unit 3 includes a housing 301. A detection cavity 303 is drilled at one end of the housing 301 close to the base 2. A sealing cover 304 is threadedly connected to the opening of the detection cavity 303. A vibration sensor 305 is slidably connected in the detection cavity 303. A rotary joint 307 is fixedly connected to the sealing cover 304, and both ends of the rotary joint 307 penetrate through the sealing cover 304 and are respectively located inside and outside the detection cavity 303. A connecting wire 306 is fixedly connected between the vibration sensor 305 and the rotary joint 307. A magnetic shielding layer 308 is coated on the outer wall of the connecting wire 306. Electromagnetic rings 310 and magnetic rings 311 with matching positions are respectively fixedly connected to the ends of the sealing cover 304 and the vibration sensor 305 close to each other. A compression spring 309 is fixedly connected between the sealing cover 304 and the vibration sensor 305.

[0027] In this embodiment, before the employee and the enterprise vehicle enter the parking lot, they need to be identified by the identification module 207 and the parking lot management system. The specific identification method can be realized through existing technologies such as two-dimensional codes and Bluetooth. At the same time, when the employee receives the base 2, they need to enter and store their vehicle model and service life for subsequent carbon emission calculations. The above identification and data entry identification methods are all well-known technologies within the field of those skilled in the art, so they will not be described in detail. Thus, the base 2 with the attached identification module 207 becomes a necessity to enter the enterprise parking lot.

[0028] Taking the vibration generated during vehicle driving as the detection object, judging the driving time of the vehicle, and matching the corresponding vehicle model to determine the carbon dioxide emissions of the current vehicle. Compared with the data filled in manually in the traditional method, the detection data of this method is more accurate. At the same time, the data is automatically generated without the need for employees to fill in separately, improving the data collection efficiency.

[0029] During the vehicle driving process, continuous vibration will be generated. When the vibration sensor 305 detects vibration data continuously for 3 minutes, the vehicle running time detection will continue until the vibration sensor 305 does not detect vibration data continuously for 1 minute. If the continuous vibration time is less than 3 minutes, it is regarded as a false detection. The vehicle state is changed from driving to stationary, and the accumulated vehicle driving time is subtracted.

[0030] In this embodiment, when the vehicle starts or stops for a long time, the cooperation of the electromagnetic ring 310 and the compression spring 309 can be used to regularly detect the working state of the vibration sensor 305: the electromagnetic ring 310 is energized, and the magnetic force generated by it and the magnetic ring 311 will compress the compression spring 309. Then the electromagnetic ring 310 is powered off, and under the action of the compressed compression spring 309, the vibration sensor 305 will be hit against the inner wall of the detection cavity 303 to obtain the detection result of the vibration sensor 305. By setting multiple different detection powers for the electromagnetic ring 310, the vibration sensor 305 can be detected multiple times. When multiple detection results meet the preset requirements, the vibration sensor 305 is in a normal working state. When the detection result does not conform to the preset state, the vibration sensor 305 is in an abnormal working state. When the vibration sensor 305 is in an abnormal working state, the recognition module 207 only retains one chance to enter the factory, reminding the staff to replace the vibration sensor 305 in time to ensure normal entry into the factory later. An automatic self-check device is added to the vibration sensor 305 to timely detect the vibration sensor 305 in an abnormal working state and remind the staff to replace it in time, increasing the accuracy of the vibration sensor 305 data collection.

[0031] Especially, in this application, the outer shells of the outer shell 301 and the vibration sensor 305 need to be made of magnetic shielding materials to reduce the influence when the electromagnetic ring 310 is started.

[0032] In summer and winter seasons, when the vehicle is driving, the air conditioner will be turned on for cooling, resulting in additional carbon emissions. Simply relying on the vehicle start time to determine the carbon emission data is no longer accurate. After the vibration detection unit 3 detects the vehicle start, the temperature detection unit 4 will also start to record the change of the interior temperature of the vehicle, and calculate the carbon emissions of the air conditioner use according to the current vehicle model and service life, which is used to correct the vehicle carbon emission detection data.

[0033] Specifically, current vehicle types are mainly divided into gasoline vehicles and new energy vehicles. Due to their different power sources, their carbon emission calculation methods are also different, and different carbon emission coefficients need to be set. The specific carbon emission coefficients of vehicles can be regularly calculated based on the fuel consumption, power consumption, and driving mileage of the vehicles.

[0034] An identification 302 is drilled at one end of the outer shell 301 away from the base 2, which is used to identify the vibration detection unit 3 and the temperature detection unit 4, facilitating maintenance and replacement work.

[0035] A dust-proof plug 5 is inserted into the spare monitoring hole 204, leaving enough preparatory structure for subsequent module expansion work.

[0036] The protection of the information interaction of the carbon neutralization system is realized through quantum communication technology, effectively protecting personal information.

[0037] The second implementation method: Figure 4 and Figures 9 - 10 As shown in the base 2, a plurality of safety holes 205 whose positions match the monitoring holes 204 are drilled in the installation part 201. Anti-disengagement units 6 are fixedly connected to the vibration detection unit 3, the temperature detection unit 4, and the dust-proof plug 5. The anti-disengagement unit 6 includes fixing nails 601 inserted into the safety holes 205, and connecting cables 604 are fixedly connected between the plurality of fixing nails 601 and the vibration detection unit 3, the temperature detection unit 4, and the dust-proof plug 5 respectively.

[0038] The vibration detection unit 3, the temperature detection unit 4, and the dust-proof plug 5 are fixed on the base 2 by using the anti-disengagement unit 6. When the vehicle encounters a traffic accident, a strong impact will occur, and there is a risk that the vibration detection unit 3, the temperature detection unit 4, and the dust-proof plug 5 will break away from the installation part 201. By using the anchoring effect of the anti-disengagement unit 6, the risk of the vibration detection unit 3, the temperature detection unit 4, and the dust-proof plug 5 flying out and causing secondary injuries to the driver and other passengers can be reduced.

[0039] A plurality of positioning rings 206 are fixedly connected to the inner wall of the safety hole 205. A plurality of anti-disengagement skirts 602 are fixedly connected to the side wall of the fixing nail 601, and the anti-disengagement skirts 602 are made of elastic materials. The interval distances of the plurality of anti-disengagement skirts 602 are the same, and the distance between adjacent positioning rings 206 increases as the distance between the positioning ring 206 and the connecting cable 604 decreases. When the vibration detection unit 3, the temperature detection unit 4, and the dust-proof plug 5 fly and pull the anti-disengagement unit 6, the collision between the plurality of positioning rings 206 and the anti-disengagement skirts 602 and the fracture of the anti-disengagement skirts 602 are used to reduce the flying speed of the vibration detection unit 3, the temperature detection unit 4, and the dust-proof plug 5, reducing their harm.

[0040] Separation grooves 603 are formed in multiple anti-detachment skirts 602. When the anti-detachment skirts 602 break, fragments will be formed, which is convenient for cleaning the broken anti-detachment skirts 602 from the safety holes 205, and is convenient for the replacement of the vibration detection unit 3, the temperature detection unit 4 and the dust plug 5.

[0041] Through the setting of the anti-detachment unit 6, the safety of using the vibration detection unit 3, the temperature detection unit 4 and the dust plug 5 is increased, and it is not easy to fly out and cause secondary injuries.

[0042] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
