[0002] In the field of modern emergency communication, satellite communication devices usually rely on fixed vehicle-mounted, airborne or shipborne platforms. Although these devices can provide stable communication services in a stable environment, in case of emergencies or extreme environments, due to their large volume, heavy weight and poor flexibility, it is difficult to meet the needs of single-soldier operations. In addition, these devices have a strong dependence on the ground communication network. Once the ground network is damaged, the communication ability will be greatly reduced, seriously affecting the efficiency of emergency response.

As Figures 1 - 5 As shown, the single-soldier portable satellite emergency communication system provided in the embodiment of the present application includes a backpack chassis 100, an integrated satellite receiver 200, a satellite antenna 300, an omnidirectional antenna 400, a self-organizing network device 500, and a power supply module 600; among them:

[0039] The backpack chassis 100 is used to accommodate the integrated satellite receiver 200, the self-organizing network device 500, and the power supply module 600;

[0040] The signal input end of the integrated satellite receiver 200 is electrically connected to the satellite antenna 300 for receiving satellite signals, and the signal output end of the integrated satellite receiver 200 is electrically connected to the self-organizing network device 500 for transmitting the processed signals to the self-organizing network device 500;

[0041] The self-organizing network device 500 is electrically connected to the integrated satellite receiver 200 for realizing audio and video communication between a single soldier and a command post or other single soldiers;

[0042] The satellite antenna 300 is connected to the outer top of the backpack chassis 100 for signal communication with the satellite;

[0043] The omnidirectional antenna 400 is connected to the left and right sides outside the backpack chassis 100 and is electrically connected to the self-organizing network device 500 through a cable for receiving and transmitting wireless signals;

[0044] The power supply module 600 adopts a plug-and-play design. The power supply module 600 is electrically connected to the integrated satellite receiver 200 and the self-organizing network device 500 to provide power for the entire system.

[0045] The single-soldier portable satellite emergency communication system provided by the embodiments of the present application integrates a satellite receiver 200, a satellite antenna 300, an omnidirectional antenna 400, a self-organizing network device 500, and a power supply module 600 onto a backpack chassis 100 to form a portable satellite emergency communication system, greatly improving the practicability and portability of the device. When a single soldier carries this system into the mission area, a communication link can be established with the satellite through the satellite antenna 300 to receive and process signals from the satellite. After the integrated satellite receiver 200 processes the satellite signals, they are transmitted to the self-organizing network device 500. The self-organizing network device 500 transmits the signals to other local devices or the command center through the omnidirectional antenna 400. The power supply module 600 provides continuous power support for the entire system to ensure the stable operation of the device during mission execution. The embodiments of the present application provide efficient and reliable communication support in extreme environments through a compact and integrated design, with obvious innovation and practicability compared to the prior art, and are particularly suitable for occasions such as emergency rescue and military operations that require rapid deployment.

[0046] The single-soldier portable satellite emergency communication system of the embodiments of the present application integrates satellite communication and self-organizing network functions and adopts a modular and lightweight design to achieve stable communication support in extreme environments, and is particularly suitable for emergency scenarios that require rapid response and flexible deployment.

[0047] In this embodiment, optionally, the self-organizing network device 500 adopts a MESH self-organizing network device, which can automatically establish communication connections with surrounding devices without fixed infrastructure to form a flexible and reliable self-organizing network. This device usually integrates core components such as a wireless communication module, an antenna module, and a routing processing unit to ensure efficient operation in different scenarios. As an efficient, flexible, and reliable communication device, the MESH self-organizing network device can maintain network connectivity and stability in various dynamic environments to ensure the efficient transmission of information.

[0048] In some embodiments, as Figure 3 shown, the integrated satellite receiver 200 integrates an uplink power amplifier 210, a downlink power amplifier 220, and a modem 230; the uplink power amplifier 210 is electrically connected to the output end of the modem 230 to enhance the uplink satellite signal; the downlink power amplifier 220 is electrically connected to the input end of the modem 230 to enhance the received downlink satellite signal; the input end of the modem 230 is electrically connected to the downlink power amplifier 220, and the output end is electrically connected to the uplink power amplifier 210 for signal modulation and demodulation.

[0049] Traditional satellite communication equipment usually disperses components such as uplink power amplifiers, downlink power amplifiers, and modems in different modules, resulting in a complex and non-portable system. In the embodiments of the present application, by integrating these key components, an efficient and compact communication system is created. This highly integrated design finds an optimal balance between portability and functionality. In the embodiments of the present application, the integrated satellite receiver 200 integrates the uplink power amplifier 210, the downlink power amplifier 220, and the modem 230, achieving signal enhancement and modulation / demodulation processing, and greatly improving the stability and quality of the system when transmitting and receiving satellite signals. The integrated power amplifier and modem ensure that the system can maintain high-quality signal transmission under harsh communication conditions. Since these components are integrated into one device, the volume and weight of the system are significantly reduced, enhancing the portability and deployment speed of the system. The single-soldier portable satellite emergency communication system in the embodiments of the present application can provide efficient satellite communication and self-organizing network functions without relying on a ground network, and is particularly suitable for single soldiers in emergency situations.

[0050] In some embodiments, as Figure 5 shown, the backpack chassis 100 is provided with heat dissipation holes 110 arranged on the left and right sides of the chassis. A layer of hydrophobic microporous membrane 111 is provided inside the heat dissipation holes 110, and a waterproof cover plate 112 is further provided outside the heat dissipation holes 110. As Figure 1 and Figure 4 shown, the waterproof cover plate 112 is fixed to the side wall of the backpack chassis 100 by screws, and the waterproof cover plate 112 and the side wall of the backpack chassis 100 are sealed by a sealing ring. The waterproof cover plate 112 is a plate body with an arc-shaped convex surface on the outer side. The waterproof cover plate 112 is fixed to the side wall of the backpack chassis 100 by screws and the waterproof cover plate 112 and the side wall of the backpack chassis 100 are sealed by a sealing ring. An air ventilation gap 1121 is opened at the lower outer side of the waterproof cover plate 112.

[0051] In this embodiment, the backpack chassis 100 opens heat dissipation holes 110 on the left and right sides of the chassis for heat dissipation. The heat dissipation design of the heat dissipation holes 110 using the hydrophobic microporous membrane 111 and the waterproof cover plate 112 can ensure the heat dissipation performance of the backpack chassis in harsh environments, while maintaining the waterproof ability and extending the service life of the device. The embodiments of the present application cleverly combine the heat dissipation design and the waterproof design, enabling the device to work stably in various environments.

[0052] The embodiments of the present application adopt a dual protection design of the hydrophobic microporous membrane 111 and the waterproof cover plate 112, which takes into account both the heat dissipation effect and the waterproofness of the device. This design is particularly suitable for use in humid, dusty, or extreme temperature environments, ensuring the reliability of the device.

[0053] Optionally, the hydrophobic microporous membrane 111 is a polytetrafluoroethylene (PTFE) hydrophobic microporous membrane. Polytetrafluoroethylene (PTFE) has excellent hydrophobicity, chemical resistance, and high-temperature stability. This material performs well in various harsh environments and can maintain its physical and chemical properties within a wide temperature range. The typical pore size of a PTFE hydrophobic microporous membrane is between 0.1 and 0.5 microns. This pore size is sufficient to prevent liquid water from passing through but allows gas to flow freely, ensuring the heat dissipation performance of the device; PTFE microporous membranes usually have a relatively thin thickness (10 - 50 microns), but have sufficient mechanical strength to withstand the mechanical stress in the device's operating environment.

[0054] In some embodiments, as Figure 4 shown, a heat dissipation device 120 is disposed inside the backpack chassis 100, and the heat dissipation device 120 is adjacent to and fixedly connected to the inner side surface of the backpack chassis 100.

[0055] In this embodiment, by disposing the heat dissipation device 120 inside the backpack chassis 100 and making the heat dissipation device 120 adjacent to and fixed to the inner side surface of the chassis, a more effective heat dissipation path is provided, ensuring the stable operation of the device in a high-temperature environment. Optionally, a heat dissipation device 120 is disposed on each of the left and right inner side surfaces of the backpack chassis 100. The heat dissipation device 120 can be a heat dissipation fan. Disposing a heat dissipation device 120 on each of the left and right sides inside the chassis can achieve more uniform heat dissipation, ensuring that the temperatures of the components inside the device are more balanced, and preventing local overheating caused by insufficient heat dissipation on one side. Moreover, heat dissipation on both sides can conduct and dissipate the heat inside the device faster, thereby improving the heat dissipation efficiency. Additionally, in extreme cases, if one side's heat dissipation device 120 fails, the heat dissipation device 120 on the other side can still partially undertake the heat dissipation task, increasing the reliability of the system.

[0056] In some embodiments, as Figure 1 shown, the power supply module 600 includes a plurality of independent detachable and pluggable battery packs 610. Each battery pack 610 can be connected to the inside of the backpack chassis 100 through an independent battery interface. A battery compartment opening 130 for inserting the battery pack 610 is provided on the outside of the backpack chassis 100 on the side of the chassis.

[0057] The power supply module 600 of the embodiment of the present application adopts a detachable and pluggable design. Multiple independent battery packs can be flexibly replaced to ensure continuous power supply for the device during long-term tasks. By designing multiple detachable battery packs, users can replace the batteries without interrupting the operation of the system, ensuring the continuous operation of the system. This design greatly improves the operability of the device and is particularly suitable for long-term emergency tasks.

[0058] In some embodiments, a backpack strap 140 for the user to carry on the back is provided on one side of the back of the backpack chassis 100. The backpack chassis 100 is made of a lightweight and high-strength material, and the overall weight of the backpack chassis 100 does not exceed 20 kilograms, so that a single soldier can easily carry it and adapt to various complex terrains, thereby improving the efficiency and mobility of mission execution.

[0059] In the prior art, ordinary metals or plastics are usually used as the material for the equipment chassis, resulting in the equipment being easily damaged or too heavy in harsh environments. In the embodiments of the present application, these problems are successfully solved by selecting a lightweight and high-strength composite material as the material for making the backpack chassis 100. In the embodiments of the present application, the backpack chassis 100 is made of a lightweight and high-strength composite material to ensure that the chassis has good impact resistance and corrosion resistance, while maintaining lightness. Using lightweight and high-strength composite materials such as carbon fiber composite materials or aluminum alloy composite materials to make the backpack chassis 100 not only reduces the weight of the equipment but also improves the durability of the equipment in extreme environments. Optionally, the material of the backpack strap 140 is selected as wear-resistant and tear-resistant high-strength nylon or polyester fiber to ensure long-term use durability in harsh environments. The connecting components (such as fasteners and adjustment buckles) of the backpack strap 140 are made of high-strength plastics or metals to ensure that they are not easily damaged under heavy loads and frequent adjustments. In addition, the backpack strap 140 can be designed as a detachable structure for easy cleaning, maintenance, or replacement. The user can choose to install or remove the backpack strap 140 according to the task requirements.

[0060] In some embodiments, the omnidirectional antenna 400 is a foldable omnidirectional fiberglass antenna. Omnidirectional antennas 400 are symmetrically arranged on the left and right sides of the backpack chassis 100, and the omnidirectional antennas 400 are connected above the left and right side walls of the backpack chassis 100.

[0061] In this embodiment, the omnidirectional antenna 400 is a foldable omnidirectional fiberglass antenna and is symmetrically installed on the left and right sides of the backpack chassis 100. This design improves the communication coverage range of the equipment and ensures the portability and deployment speed of the system. The foldable omnidirectional fiberglass antenna enables the antenna to be stored when not in use, reducing the volume of the equipment, and can significantly improve the signal coverage range when unfolded. This design not only ensures the portability of the system in a compact form but also improves the communication ability of the equipment in various complex environments.

[0062] In some embodiments, the satellite antenna 300 is in a horn shape and is electrically connected to the signal input end of the integrated satellite receiver 200 through a cable for receiving and transmitting satellite signals. The horn-shaped satellite antenna is connected to the integrated satellite receiver 200 through a cable, optimizing the receiving and transmitting efficiency of satellite signals, and is particularly suitable for communication over long distances and in harsh environments. The horn-shaped satellite antenna design helps to concentrate the reception and transmission of satellite signals, improving the signal strength and transmission quality.

[0063] In some embodiments, the material of the backpack chassis 100 is carbon fiber composite material or aluminum alloy composite material. This material has the advantages of high strength and light weight, while providing excellent durability and environmental adaptability, and is particularly suitable for scenarios that require frequent movement and long-term use. The selection of this material makes the device both lightweight and sturdy, greatly improving the overall performance of the device.

[0064] The working principle of the single-soldier portable satellite emergency communication system according to the embodiments of the present application is as follows:

[0065] When a single soldier carries the system into the mission area, the satellite antenna 300 communicates with the satellite to establish a communication link, and transmits the received signal to the integrated satellite receiver 200 for processing. The uplink power amplifier 210 enhances the transmitted signal, the downlink power amplifier 220 enhances the received signal, and the modem 230 completes the modulation and demodulation of the signal. The processed signal is transmitted to the omnidirectional antenna 400 through the ad hoc network device 500 to achieve audio and video communication with the command post or other single soldiers. The power supply module 600 provides continuous power support for the system to ensure the continuous operation of the device in a complex environment.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
