Description

Technical Field

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

[0002] Quantum secure communication is a secure communication technology that combines QKD (Quantum Key Distribution) with other cryptographic technologies. As a typical application of quantum communication, QKD generates and distributes keys by transmitting quantum states. When the communicating parties distribute keys through QKD, any theft will be discovered in time due to the disturbance of the quantum state. As a key distribution component in cryptography, QKD can be combined with a variety of encryption and identification technologies to form quantum secure communication solutions 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 tree planting, energy conservation and emission reduction, etc., the carbon dioxide or greenhouse gas emissions generated by themselves can be offset to achieve positive and negative offset and achieve relative "zero emissions". For enterprises, carbon emissions mainly come from production, office, transportation and 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 for the above scenarios, and aggregate them to the processing terminal through the network for processing. Once data leakage occurs during the above data transmission process, it is easy to cause leakage of corporate production, office and employee personal information.

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

[0005] With the development of carbon neutralization technology, the data demand for the 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 traditional data transmission method has low security. 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 traditional data transmission method has low security.

[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;

[0008] 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 far from the monitoring holes is fixedly connected to an identification module.

[0009] 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 realized through quantum communication technology, and the enterprise production information and personal information are effectively protected.

[0010] 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 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 running time is subtracted.

[0011] 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 the sealing cover and are located on both sides inside and outside the detection cavity respectively. A connecting wire is fixedly connected between the vibration sensor and the connector. 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.

[0012] Preferably, an identification mark is drilled at one end of the housing away from the base to identify the vibration detection unit and the temperature detection unit, which is convenient for maintenance and replacement work.

[0013] Preferably, a dust-proof plug is inserted into the spare monitoring hole, leaving enough preparatory structure for subsequent module expansion work.

[0014] Preferably, a plurality of safety holes whose positions match the monitoring holes are drilled on the installation part. 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. Connecting cables are 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.

[0015] Preferably, a plurality of positioning rings are fixedly connected to the inner wall of the safety hole. A plurality of anti-disengagement skirts are fixedly connected to the side wall of the fixing nail, and the anti-disengagement skirts are made of elastic materials. The interval distances of the plurality of anti-disengagement skirts are the same. 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 damage.

[0016] Preferably, a separation groove is drilled on 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 out of the safety hole and convenient for the replacement work of the vibration detection unit, the temperature detection unit, and the dust-proof plug.

[0017] In summary, in this application, the symmetric quantum key pairs generated by the key distribution center are respectively pre - set in the quantum - secure service key distribution center 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 filled 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.

[0018] When the mobile terminal communicates with the user terminal, identity authentication is completed through the key distribution center using some 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 using the OTP or other symmetric - key encryption algorithms.

[0019] Through quantum communication technology, the protection of information interaction in the carbon - neutral system is realized, effectively protecting enterprise production information and personal information. Taking the vibration generated during vehicle driving as the detection object, the vehicle start time is judged, and the current vehicle carbon dioxide emission is determined. Compared with the data filled in manually in the traditional method, the detection data in this method is more accurate. 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.

[0020] Finally, the vibration detection unit, temperature detection unit, and dust - proof plug are fixed on the base using the anti - detachment unit. When the vehicle encounters a traffic accident, a strong impact will occur, and there is a risk that the vibration detection unit, temperature detection unit, and dust - proof plug will break away from the installation part. Using the anchoring effect of the anti - detachment unit, the risk of secondary injury to the driver and other passengers caused by the vibration detection unit, temperature detection unit, and dust - proof plug flying out can be reduced.

Specific embodiments

[0033] The following will make a detailed description of the two embodiments of the present application with reference to the accompanying drawings.

[0034] The first embodiment:

[0035] 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;

[0036] The symmetric quantum key pairs generated by the key distribution center are respectively preset 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 accesses for the first time or the key is exhausted, a certain amount of keys can be refilled through the quantum key update device and preset in the secure storage medium (such as a smart cryptographic key, a secure chip, etc.) of the mobile terminal for authentication and session encryption in its subsequent communication process.

[0037] 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 (One Time Pad) or other symmetric key encryption algorithms.

[0038] Please refer to Figure 2 , on the above basis, taking the data transmission system of enterprise carbon neutralization as an example, the mobile terminal includes a vehicle and a monitoring module.

[0039] Please refer to Figures 3 - 5 , the monitoring module includes a base 2 installed on the center control display screen 1 of the vehicle. The base 2 includes a mounting portion 201. One end of the mounting portion 201 close to the center 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 center 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;

[0040] 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 connector 307 is fixedly connected to the sealing cover 304, and both ends of the connector 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 connector 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.

[0041] In this embodiment, before an employee and an enterprise vehicle enter the parking lot, they need to be recognized by the recognition module 207 and the parking lot management system. The specific recognition method can be realized by 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 calculation. The above recognition and data entry recognition methods are 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 recognition module 207 becomes a necessity to enter the enterprise parking lot.

[0042] 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 emission 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.

[0043] During the vehicle driving process, continuous vibration will be generated. When the vibration sensor 305 continuously detects vibration data for 3 minutes, the vehicle running time detection will continue until the vibration sensor 305 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 is changed from driving to stationary, and the accumulation of the vehicle driving time is subtracted.

[0044] In this embodiment, when the vehicle starts or parks 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. Adding a self-check device to the vibration sensor 305 can 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.

[0045] Particularly, 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.

[0046] In summer and winter, when the vehicle is in motion, the air conditioner is turned on for cooling, resulting in additional carbon emissions. It is no longer accurate to solely rely on the vehicle startup time to determine carbon emission data. After the vibration detection unit 3 detects the vehicle startup, the temperature detection unit 4 will also start recording the temperature change inside the vehicle and calculate the carbon emissions of air conditioner use based on the current vehicle model and service life, for correcting the vehicle carbon emission detection data.

[0047] Particularly, currently vehicle types are mainly divided into fuel 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 the vehicle can be regularly calculated according to the fuel consumption, power consumption, and driving mileage of the vehicle.

[0048] At one end of the housing 301 away from the base 2, a mark 302 is drilled, used to mark the vibration detection unit 3 and the temperature detection unit 4, facilitating maintenance and replacement work.

[0049] A dust-proof plug 5 is inserted into the spare monitoring hole 204, leaving sufficient preparatory structure for subsequent module expansion work.

[0050] Through quantum communication technology, the protection of information interaction of the carbon neutralization system is realized, effectively protecting personal information.

[0051] The second implementation method:

[0052] 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 on 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 pins 601 inserted into the safety holes 205, and connecting cables 604 are fixedly connected between the plurality of fixing pins 601 and the vibration detection unit 3, the temperature detection unit 4, and the dust-proof plug 5 respectively.

[0053] 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.

[0054] A plurality of positioning rings 206 are fixedly connected to the inner wall of the safety hole 205. A plurality of anti - detachment skirt edges 602 are fixedly connected to the side wall of the fixing nail 601, and the anti - detachment skirt edges 602 are made of an elastic material. The spacing distances between the plurality of anti - detachment skirt edges 602 are the same. The spacing 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 plug 5 fly and traction the anti - detachment unit 6, the collision between the plurality of positioning rings 206 and the anti - detachment skirt edges 602 and the fracture of the anti - detachment skirt edges 602 are used to reduce the flying speed of the vibration detection unit 3, the temperature detection unit 4, and the dust plug 5, thereby reducing their damage.

[0055] Separation grooves 603 are formed in each of the plurality of anti - detachment skirt edges 602. When the anti - detachment skirt edges 602 break, fragments will be formed, which is convenient for cleaning the broken anti - detachment skirt edges 602 from the safety hole 205, and is convenient for the replacement work of the vibration detection unit 3, the temperature detection unit 4, and the dust plug 5.

[0056] 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 they are not likely to fly out and cause secondary injuries.

[0057] Combined with the current actual needs, the above - mentioned implementation manner adopted in this application, the protection scope is not limited to this. Within the knowledge scope of 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.
