Description

Technical Field

[0001] This invention relates to the field of communication technology, specifically to a magnetic quantum field network access system and method compatible with existing communication equipment. Background Technology

[0002] Currently, the field of wireless communication uses traditional electromagnetic fields as the information transmission carrier. This type of communication has undergone multiple generations of technological iteration and has been widely used in various scenarios. However, in actual engineering applications, there are still many technical shortcomings that are difficult to overcome, which cannot meet the development needs of the next generation of communication technologies.

[0003] First, traditional electromagnetic waves have limited penetration capabilities and are easily absorbed or shielded by media such as walls, metals, and water. In complex obstruction scenarios such as basements, tunnels, and underwater environments, signal attenuation is severe, leading to unstable or even interrupted communication links, making it difficult to achieve seamless communication across all scenarios. The need for communication in such extreme environments is increasingly urgent in fields such as military communications, marine monitoring, and underground exploration. Second, traditional electromagnetic communication is susceptible to interference from co-channel signals and external electromagnetic interference, resulting in issues such as bit errors and packet loss during signal transmission, leading to insufficient communication reliability. Furthermore, with the increasing number of communication devices, spectrum resources are becoming increasingly congested, further exacerbating interference problems. Third, traditional electromagnetic communication technology is gradually approaching its physical and thermodynamic limits, leaving extremely limited room for performance improvements through spectrum optimization and other methods, making it difficult to meet the core requirements of next-generation communication for longer transmission distances, higher transmission rates, and lower operating power consumption.

[0004] With the development of quantum communication technology, magnetic quantum fields, with their inherent advantages such as strong penetration, excellent anti-interference performance, and stable transmission, have become an important direction for breaking through the bottlenecks of traditional electromagnetic communication technology. They have shown technical potential that traditional electromagnetic waves cannot match in cross-medium communication and communication in complex environments. However, a technological transition system centered on magnetic quantum communication has not yet been formed in the current technology. Existing single magnetic field communication schemes have poor compatibility and cannot gradually achieve a comprehensive upgrade to magnetic quantum communication technology while retaining existing communication network infrastructure and terminal equipment. Directly discarding existing communication equipment and networks would result in huge equipment waste and high network reconstruction costs.

[0005] Meanwhile, existing magnetic field communication schemes mostly use a single-frequency magnetic field for information transmission, which cannot simultaneously meet the dual requirements of long-distance communication and high-speed transmission. Although a single low-frequency magnetic field can achieve long-distance, strong-penetration communication, the transmission rate is low, making it difficult to meet the high-speed data transmission needs of high-definition video, large files, etc.; while a single high-frequency magnetic field can achieve high-speed transmission, the transmission distance is short and the penetration ability is weak, making it unsuitable for complex obstruction scenarios. In addition, existing technologies have not solved the bidirectional compatibility problem between magnetic quantum communication and existing traditional electromagnetic communication, resulting in the inability of the two technologies to operate in parallel and the inability to achieve a smooth transition from traditional electromagnetic communication to magnetic quantum communication, which seriously restricts the industrial application and promotion of magnetic quantum communication technology.

[0006] Based on the shortcomings of the existing technologies, there is an urgent need for a communication method and system that can achieve a smooth transition between magnetic quantum communication and existing traditional electromagnetic communication, meet the communication needs of all scenarios, have strong compatibility and controllable cost, so as to solve the many deficiencies of the existing technologies.

[0026] This invention provides a magnetic quantum field network access system and method compatible with existing communication equipment. It has the following beneficial effects:

[0027] 1. This invention enables a smooth transition between magnetic quantum communication technology and existing traditional electromagnetic communication technology.

Attached Figure Description

[0030] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0031] The following will refer to the appendix to the specification of this invention. Figure 1 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] The core of this invention, a magnetic quantum field-based compatible communication method and system, is to generate four switchable common magnetic quantum fields through a magnetic quantum field transmitting base station. This, combined with a frequency intelligent switching module, enables dynamic adaptation of long-wave, medium-wave, and short-wave magnetic fields. The system achieves a smooth transition with existing conventional electromagnetic communication technologies in two stages. Simultaneously, terminal-specific coding enables parallel communication between multiple devices, ensuring the stability and reliability of the communication link. The following two core embodiments detail the specific implementation process and technical aspects of this invention.

[0033] Example 1: Specific Implementation of the First Phase of Compatible Transitional Communication

[0034] This embodiment corresponds to the first compatible transition stage of the present invention. The core is to realize the parallel operation of magnetic quantum communication and existing traditional electromagnetic communication without modifying the hardware of the transmitter of the existing communication equipment. Bidirectional compatibility is achieved by adding a traditional electromagnetic communication receiver adapter module, and the native magnetic quantum communication terminal is deployed in a pilot phase at the same time. The specific implementation steps are as follows.

[0035] The first step involves base station deployment and the establishment of a public magnetic quantum field. Magnetic quantum field transmitting base stations are deployed across the entire target communication area. The spacing between base stations is set according to communication coverage requirements to ensure comprehensive coverage of the public magnetic quantum field without blind spots. Each magnetic quantum field transmitting base station has a built-in magnetic field generation module, control module, power supply module, and communication interface module. The magnetic field generation module consists of a magnetic core assembly and a power drive unit. The control module uses a microcontroller, and the power supply module provides stable power to all components of the base station. In this embodiment, the base station preferentially uses a combination of hard and soft magnets in a DC mode to generate the public magnetic quantum field. A hard permanent magnet and a soft magnet are combined in a 1:2 volume ratio as the magnetic core, connected to a DC power supply. The current is adjusted by a series resistor to regulate the magnetic field strength to 0.5T, generating a composite public magnetic quantum field that balances magnetic field stability and modulation flexibility.

[0036] The second step involves the installation and debugging of the traditional electromagnetic communication receiver adapter module. A traditional electromagnetic communication receiver adapter module is installed on the network side. This module integrates a signal conversion unit, a filtering unit, and an interface unit. The interface unit interfaces with both existing traditional electromagnetic communication equipment and the magnetic quantum field communication network. After installation, debugging is performed. During debugging, it is ensured that the signal conversion unit can accurately convert the electromagnetic wave signals emitted by the existing traditional electromagnetic communication equipment into electrical signals suitable for magnetic quantum field transmission, that the filtering unit can effectively filter out clutter signals, and that the conversion delay is controlled within 10ms, achieving bidirectional signal compatibility between the existing communication equipment and the magnetic quantum field communication network.

[0037] The third step is communication link debugging and operation. After debugging, the magnetic quantum field transmitting base station is activated to continuously transmit a composite public magnetic quantum field. Core communication services are prioritized for transmission through the magnetic quantum field. Existing traditional electromagnetic communication devices, including mobile phones and computers, transmit electromagnetic wave signals that are converted by a traditional electromagnetic communication receiving adapter module before accessing the magnetic quantum field communication network to achieve normal communication functions such as calls and internet access, without any difference from existing communication modes. Simultaneously, a pilot deployment of a native magnetic quantum communication terminal equipped with a magnetic modulation module is conducted. This terminal has a built-in DC magnetic modulation module dedicated encoding chip signal analysis module and power supply module. The power supply module provides 5V DC power to drive the DC magnetic modulation module to generate controllable magnetic disturbances. Through the 32-bit dedicated code stored in the dedicated encoding chip, the public magnetic quantum field is encoded and disturbed to achieve native magnetic quantum communication.

[0038] The fourth step is intelligent frequency switching and control. The intelligent frequency switching module collects communication parameters in real time, including communication distance, signal strength, and data transmission rate requirements. The scene detection unit of this module consists of a distance sensor, a signal strength detector, and an obstruction detector, transmitting the collected parameters to the switching control unit. The switching control unit communicates with the control module of the magnetic quantum field transmitting base station, automatically switching the magnetic field frequency band according to preset thresholds. When the user is in a severely obstructed area such as a basement elevator or is conducting long-distance communication, the switching control unit outputs a command to control the base station to switch to the long-wave magnetic field frequency band (1kHz to 10kHz) to ensure stable communication links. When the user is in a typical urban building environment, it switches to the medium-wave magnetic field frequency band (10kHz to 100kHz) to balance transmission distance and speed. When the user is performing high-speed data interactions such as high-definition video playback and large file transfers, it switches to the short-wave magnetic field frequency band (100kHz to 1MHz) to meet high-speed transmission requirements.

[0039] In this embodiment, the two communication modes operate in parallel, and the existing traditional electromagnetic communication equipment and the pilot native magnetic quantum communication terminal do not interfere with each other. The frequency intelligent switching module realizes full-scenario communication adaptation and completes the communication requirements of the compatibility transition phase.

[0040] Example 2: Specific Implementation of the Second Stage of Pure Magnetic Quantum Communication

[0041] This embodiment corresponds to the second comprehensive upgrade stage of the present invention. The core is to achieve full coverage of pure magnetic quantum communication, disable traditional electromagnetic communication transmission links, and complete the complete transition from traditional electromagnetic communication to magnetic quantum communication. The specific implementation steps are as follows.

[0042] The first step is to optimize the magnetic quantum field communication network. This involves upgrading and optimizing all deployed magnetic quantum field transmitting base stations across the entire region, improving the magnetic field generation and control modules of the base stations, and ensuring that the base stations can flexibly switch between four common magnetic quantum field modes: rigid fixed magnet and DC mode, soft magnet and high-voltage AC mode, combination of hard and soft magnets and DC mode, and soft magnet and high-voltage DC mode. Each mode allows for flexible adjustment of magnetic field strength and operating parameters according to communication scenario requirements. Simultaneously, the base station deployment density is optimized to ensure comprehensive coverage of the common magnetic quantum field and improve the stability of the communication link.

[0043] The second step involves terminal replacement and debugging. All existing traditional electromagnetic communication terminals are replaced with next-generation magnetic quantum communication terminals. These terminals integrate a DC magnetic modulation module, a dedicated encoding chip, a signal analysis module, a power supply module, and a communication antenna. The DC magnetic modulation module consists of coil components and a drive circuit. The power supply module provides 12V DC power to drive the DC magnetic modulation module to generate controllable magnetic disturbances. The dedicated encoding chip stores a unique 32-bit code for encoding control during the magnetic disturbance process. The signal analysis module analyzes the magnetic field disturbance signal to reconstruct the original data. After the terminal replacement is completed, each terminal is debugged to ensure it can accurately receive the common magnetic quantum field signal and distinguish signals through dedicated encoding, completing the entire process of magnetic disturbance encoding and signal analysis.

[0044] The third step is to disable the traditional electromagnetic communication link. After completing the terminal replacement and debugging, the traditional electromagnetic communication transmission link is disabled, the traditional electromagnetic communication receiving adapter module on the network side is removed, and the entire domain is switched to pure magnetic quantum communication mode. The magnetic quantum field transmitting base station flexibly switches between four common magnetic quantum field modes according to the communication scenario requirements. For example, in high-precision communication scenarios, a soft magnet and high-voltage DC power mode is selected, connected to a 20kV to 60kV high-voltage DC power supply, and the magnetic field strength is adjusted to 0.8T through a high-precision voltage regulator to achieve precise communication; in scenarios that require rapid modulation of the magnetic field, a soft magnet and high-voltage AC power mode is selected, connected to a 10kV to 50kV high-voltage AC power supply, and the frequency is set to 50Hz to 100Hz to generate an alternating common magnetic quantum field.

[0045] The fourth step involves full-scenario communication operation and control. The pure magnetic quantum communication network is activated. The terminal, driven by DC current, uses a DC magnetic modulation module to controllably perturb the shared magnetic quantum field according to its proprietary encoding, achieving data transmission. The receiving terminal, through proprietary encoding matching, accurately analyzes the magnetic field perturbation signal, reconstructs the original data, and completes the communication process. The intelligent frequency switching module continuously collects communication parameters and automatically switches between long-wave, medium-wave, and short-wave magnetic field frequency bands, achieving full adaptability for long-distance, high-speed transmission and complex communication scenarios. Simultaneously, signal interaction between system modules uses AES128 encryption algorithm for proprietary encoding encryption, and the communication link between the terminal and the base station adopts full-duplex mode, achieving bidirectional synchronous data transmission.

[0046] In this embodiment, the pure magnetic quantum communication network achieves full coverage, allows flexible switching between four common magnetic quantum field modes, intelligent adaptation of long-wave, medium-wave, and short-wave magnetic fields, low power consumption of the terminal, and interference-free parallel communication of multiple devices, thus completing a smooth transition from traditional electromagnetic communication to magnetic quantum communication and meeting the full-scenario requirements of next-generation communication.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
