Description

Technical Field

[0001] The utility model relates to the field of underwater communication, in particular to an underwater wireless real-time voice communication system. Background Art

[0002] In an underwater environment, sound wave propagation is affected by water, resulting in signal attenuation, distortion and delay. This may result in poor quality of received voice signals, including noise interference, fuzzy voice, sound deformation and other problems, affecting the clarity and accuracy of communication.

[0003] At present, most underwater communication equipment uses acoustic communication, that is, using sound waves in the water to transmit information. However, acoustic communication is affected by environmental factors such as water quality, water temperature, and water flow. The communication distance is limited, and it is limited by the frequency band and bandwidth, resulting in a relatively single communication method that is difficult to meet complex communication needs. In addition, underwater communication equipment usually faces challenges in data security. Due to the particularity of underwater communication channels, transmitted data is susceptible to eavesdropping, interference, and tampering. Current encryption technology is rarely used in underwater environments, which makes data easy to be obtained and tampered with by attackers, posing security risks.

[0004] Furthermore, since the communication distance of underwater communication equipment is usually short, it is affected by water absorption, scattering and multipath effects, resulting in limited signal transmission distance. This limits the application of underwater communication equipment in large-scale seabed exploration, deep-sea exploration and other fields. Underwater communication equipment often faces interference from underwater sound sources, underwater organisms, hydroacoustic sensors, etc. The interference signal may be mixed with the target signal, resulting in a decrease in communication quality or even failure of normal communication. Existing high-performance underwater communication equipment usually has expensive R&D and production costs, which limits its widespread application in commercial and scientific research fields, especially for small and medium-sized enterprises and research institutions, where cost may be a limiting factor.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0035] Implementation method 1, see Figure 1 The underwater wireless real-time voice communication system described in this embodiment includes:

[0036] surface deck units and underwater portable intercom units;

[0037] The underwater portable intercom unit includes an electronic compartment, an analog circuit processing module, a DSP core processing module and a transducer module;

[0038] The electronic compartment provides electrical energy for the analog circuit processing module, the DSP core processor and the transducer module;

[0039] The analog circuit processing module includes a signal input submodule and a voice modulation submodule;

[0040] The signal input submodule is used to collect the audio signal transmitted by the surface deck unit, and convert the collected audio signal into an electrical signal and transmit it to the voice modulation module; the voice modulation module modulates the electrical signal into a single sideband modulation signal;

[0041] The speech modulation module is connected to the DSP core processing module, and the single-sideband modulation signal is transmitted to the DSP core processing module;

[0042] The DSP core processing module receives the single sideband modulated signal and performs modulation processing on the signal, and transmits the modulated signal to the transducer module;

[0043] The transducer module converts the modulated signal into a sound signal.

[0044] The system described in this embodiment can effectively improve the quality of underwater voice communication and reduce signal distortion and noise through digital signal processing (DSP) and high-quality analog circuit processing. The single-sideband modulation signal technology is introduced to expand the communication mode, enhance the flexibility and adaptability of the system, and enable it to better adapt to different underwater communication environments. The DSP core processing module can integrate data encryption and decryption functions, enhance the security of communication, prevent data from being illegally eavesdropped or tampered with, thereby improving the confidentiality and integrity of the data. The system is designed for real-time voice communication and can be used in underwater operations, search and rescue operations, scientific research and other fields, improving the efficiency and safety of underwater mission execution.

[0045] In this embodiment, the audio signal transmitted by the surface deck unit is collected by the signal input submodule, converted into an electrical signal, and then transmitted to the voice modulation submodule. The voice modulation submodule modulates the electrical signal into a single-sideband modulation signal, which effectively reduces the bandwidth requirement for signal transmission. The single-sideband modulation signal is transmitted to the DSP core processing module for digital signal processing, including demodulation, filtering, enhancement and other processing to improve the quality and clarity of the voice signal. The processed signal is transmitted to the transducer module to convert the digital signal into an analog sound signal for propagation and reception in an underwater environment. The purpose of the system described in this embodiment is to propose an advanced underwater wireless real-time voice communication system to meet the needs of underwater communication and improve the efficiency and security of underwater communication in response to the problems of poor voice signal quality, single communication method and poor data security of domestic products. By improving the quality of voice signals, introducing new communication methods and strengthening data security, the system aims to solve the problems existing in existing underwater communication systems and promote the development and application of underwater communication technology.

[0046] Implementation method 2: This implementation method further limits the underwater wireless real-time voice communication system described in implementation method 1, wherein the DSP core processing module includes a voice enhancement submodule, an encryption submodule and a low-pass filter;

[0047] The speech enhancement module is used to receive a single sideband modulated signal and perform signal enhancement on the single sideband modulated signal, and the enhanced signal is transmitted to the encryption module;

[0048] The encryption module receives the enhanced signal and performs encryption processing on the signal, and the encrypted signal is transmitted to the low-pass filter;

[0049] The low-pass filter receives the encrypted signal and removes low-frequency noise, and performs coherent demodulation on the single-sideband modulated signal after the noise is removed.

[0050] In this embodiment, by introducing the voice enhancement submodule, the system can enhance the received single-sideband modulated signal, improve the clarity and quality of the voice, and thus better deal with the problems of noise and signal attenuation in underwater communication. The introduction of the encryption submodule further improves the data security of the system. By encrypting the enhanced signal, the encryption module adopts the existing logistic chaos algorithm encryption technology, and the system can better protect the communication content from unauthorized access and eavesdropping. The use of a low-pass filter helps to remove low-frequency noise in the encrypted signal and improves the anti-interference ability of the system. This is particularly important for the low-frequency noise common in underwater environments. Coherent demodulation of the single-sideband modulated signal after removing the noise through a low-pass filter helps to restore the original voice signal and improve the accuracy and stability of communication. And through digital real-time modulation and demodulation technology, it is also possible to realize real-time writing, real-time modulation and demodulation of language signals and real-time output of modulated signals. It can upgrade the half-duplex communication of traditional walkie-talkies to full-duplex communication, and change from "walkie-talkies" to "making calls".

[0051] Specifically, the speech enhancement submodule receives the single-sideband modulated signal and performs signal enhancement processing on it, including noise reduction, sound enhancement and other technologies to improve the quality of the speech signal. The encryption submodule receives the speech-enhanced signal, encrypts it, and uses the existing logistic chaos algorithm encryption technology to protect the security of the communication content and prevent unauthorized access. The low-pass filter receives the encrypted signal, removes low-frequency noise, and retains high-frequency components to reduce the signal bandwidth, improve noise resistance, and reduce the bandwidth required for signal transmission. The signal processed by the low-pass filter is coherently demodulated to restore the original speech signal to make it more in line with the auditory characteristics of the human ear.

[0052] Through the voice enhancement submodule, the system can provide a clearer and higher-quality voice experience in underwater communications and improve the effect of communication. The introduction of the encryption submodule helps prevent unauthorized access and eavesdropping, and improves the data security of the underwater communication system. The use of a low-pass filter can effectively remove low-frequency noise and improve the system's anti-interference ability in a noisy underwater environment. Coherent demodulation restores the processed signal, which helps improve the accuracy and stability of communication and ensures the correct transmission of voice information.

[0053] In summary, implementation method 2 has achieved significant progress in voice quality, data security, noise resistance, and communication stability, making the underwater wireless real-time voice communication system more suitable for complex underwater environments.

[0055] In this embodiment, waterproof microphones and waterproof headphones are introduced, making the entire underwater wireless real-time voice communication system more adaptable to the underwater environment and able to work reliably in scenes such as diving and underwater operations. The sound signal is converted into an electrical signal through the microphone, and then the electrical signal is converted back into a sound signal through the waterproof headphones, which reduces the loss and distortion of the signal and improves the transmission efficiency and fidelity of the signal. The use of waterproof microphones and waterproof headphones improves the water resistance and corrosion resistance of the system, reduces the possibility of equipment failure due to underwater environmental factors, and enhances the reliability of the system.

[0056] In practical applications, a microphone is a device for receiving sound signals and converting them into electrical signals. In underwater communication systems, waterproof microphones can accurately capture sound signals in underwater environments and convert them into electrical signals for subsequent processing and transmission. Waterproof headphones are devices for receiving electrical signals and converting them into sound signals. In underwater communication systems, waterproof headphones can convert received electrical signals into sound signals so that underwater personnel can hear the voice information sent by the other party. By introducing waterproof microphones and waterproof headphones, the impact of the underwater environment on the equipment can be effectively dealt with, and the reliability and stability of the underwater communication system can be improved. Accurately converting sound signals into electrical signals through microphones, and converting electrical signals back into sound signals through waterproof headphones, can ensure the quality and integrity of voice signals during transmission, and improve the clarity and intelligibility of communication. Waterproof microphones and waterproof headphones have good waterproof and corrosion resistance, and can work stably for a long time in underwater environments, thereby enhancing the water resistance and corrosion resistance of the entire underwater communication system and extending the service life of the equipment.
