However, when users take portable emergency communication devices into forests, deserts, or other locations far from where stable power can be provided, the portable power supply may be insufficient, causing the communication devices to malfunction and reducing their reliability, thus preventing timely communication in emergencies.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0035] Figure 1 This is a schematic diagram of the structure of a communication device provided in an embodiment of the present invention, such as... Figure 1 As shown, the communication device includes at least a photovoltaic base station backpack 20. The photovoltaic base station backpack 20 includes a communication base station module 21, a photovoltaic module 22, an energy storage module 23, and a voltage conversion module 24; the voltage conversion module 24 includes a power input terminal E2 and a power output terminal E3; the voltage conversion module 24 is electrically connected to the energy storage module 23 and the communication base station module 21, respectively.

[0036] Specifically, when the power input terminal E2 is electrically connected to the photovoltaic module 22, the voltage conversion module 24 receives the photovoltaic electrical signal from the photovoltaic module 22; when the power input terminal E2 is electrically connected to the adapter 27, the voltage conversion module 24 receives the grid-side electrical signal from the adapter 27.

[0037] The photovoltaic base station backpack 20 may include two shoulder straps for user carrying. The communication base station module 21 includes a portable broadband self-organizing network station, which can quickly build a temporary dedicated communication network in areas without traditional communication networks, enabling voice, video, or data communication within a certain range. The photovoltaic module 22 includes photovoltaic panels and other photoelectric conversion devices; the energy storage module 23 includes battery packs; the voltage conversion module 24 includes boost converters and / or buck converters; the adapter 27 may include rectifier devices that convert AC signals to DC signals; and the power output terminal E3 may be a USB port, etc., which can be configured according to actual needs and are not specifically limited here.

[0038] Specifically, within the area where power can be obtained, adapter 27 can be plugged into the power input terminal E2 of voltage conversion module 24, and the other end of adapter 27 can be electrically connected to the mains power supply terminal to convert the AC signal provided by the mains power supply terminal into a DC signal and transmit it to voltage conversion module 24. Voltage conversion module 24, as needed, converts the DC signal provided by adapter 27 into voltage and stores it in energy storage module 23. Thus, when a user carrying photovoltaic base station backpack 20 and walkie-talkie 10 enters an area without power supply and network signal, the electrical energy 23 stored in energy storage module 23 can provide power to communication base station module 21 and external communication equipment (such as walkie-talkie). Communication base station module 21 can transmit wireless communication signals under the action of electrical signals. This wireless communication signal can cover a certain area, for example, the wireless communication signal transmitted by communication base station module 21 can cover an area with a radius of 500 meters to 1000 meters from communication base station module 21, or other areas, which are not specifically limited here. Communication base station module 21 can be applied to outdoor search and rescue scenarios with communication in a small area. In addition, the photovoltaic base station backpack 20 is also equipped with a photovoltaic module 22. When the user is in an outdoor environment or the user is not charging the energy storage module 23 through the adapter 27, the user can connect the photovoltaic module 22 to the power input terminal E2. This allows the photovoltaic module 22 to convert sunlight into electrical signals, which can then be transmitted to the voltage conversion module 24 to provide power to the communication base station module 21 and store it in the energy storage module 23. Alternatively, it can directly charge external communication equipment through the power output terminal E3. This ensures the communication reliability of the communication base station module 21 and the power stability of the energy storage module 23. The photovoltaic base station backpack 20 can provide a stable and reliable power supply signal to external communication equipment and the communication base station module 21, improving the reliability and battery life stability of communication equipment in outdoor environments.

[0039] The technical solution of this invention involves setting a photovoltaic base station backpack in a communication device, comprising a communication base station module, a photovoltaic module, an energy storage module, and a voltage conversion module. The voltage conversion module includes a power input terminal and a power output terminal, and is electrically connected to both the energy storage module and the communication base station module. Thus, when the adapter is electrically connected to the power input terminal, the voltage conversion module can store the electrical energy provided by the adapter in the energy storage module. When the user is in an outdoor environment and cannot obtain a stable grid-side electrical signal through the adapter, the photovoltaic module is electrically connected to the power input terminal, enabling the photovoltaic module to provide a stable electrical signal to both the energy storage module and the communication base station module. This improves the power stability of the energy storage module, allowing the communication base station module to provide a stable wireless communication signal. Simultaneously, the electricity stored in the energy storage module can provide a stable power supply signal to external communication equipment, improving the reliability and battery life of the communication equipment.

[0040] It is understood that the external communication device electrically connected to the power output terminal E3 can be a smart terminal or a handheld walkie-talkie, etc., and can be configured according to actual needs. In an optional embodiment, Figure 2 This is a schematic diagram of another communication device provided in an embodiment of the present invention, such as... Figure 2 As shown, the communication device also includes a walkie-talkie 10, which includes a power input terminal E1. When the power output terminal E3 is plugged into the power input terminal E1, the voltage conversion module 24 is used to provide a power supply signal to the walkie-talkie 10.

[0041] Among them, the walkie-talkie 10 is a terminal device that enables short-range instant communication without relying on public networks, using radio waves. The overall structure of the walkie-talkie 10 is small, making it convenient for users to carry and use outdoors.

[0042] Specifically, by including a power input terminal E1 in the walkie-talkie 10, when the walkie-talkie 10 has low battery or is powered off, the power output terminal E3 can be plugged into the power input terminal E1, so that the voltage conversion module 24 can transmit the electrical energy stored in the energy storage module 23 or the electrical energy provided by the photovoltaic module 22 to the walkie-talkie 10, thereby improving the battery life reliability of the walkie-talkie 10 in outdoor environments and enhancing the user experience.

[0043] Optional, Figure 3 This is a schematic diagram of the structure of another communication device provided in an embodiment of the present invention, such as... Figure 3 As shown, the voltage conversion module 24 includes at least a first voltage conversion unit 241, which is electrically connected to the power input terminal E2 and the first voltage input / output terminal E4 respectively. The first power conversion unit is used to convert the power signal provided by the power input terminal E2 into a first voltage signal and output it to the first voltage input / output terminal E4. The energy storage module 23 and the communication base station module 21 are electrically connected to the first voltage input / output terminal E4 respectively.

[0044] The first voltage conversion unit 241 may include a boost converter and / or a buck converter, etc. The first voltage signal may be a fixed value or a non-fixed value. Optionally, the first voltage signal may be the rated voltage of the energy storage module 23 and the operating voltage of the communication base station module 21. For example, the first voltage signal is 24V, which can be set according to actual needs and is not specifically limited here.

[0045] Specifically, by setting a first voltage conversion unit 241, the electrical signal provided by the power input terminal E2 is boosted or bucked and then transmitted to the energy storage module 23 and the communication base station module 21, so as to increase the amount of electricity stored in the energy storage module 23 and maintain the working stability of the communication base station module 21.

[0046] Optional, Figure 4This is a schematic diagram of another communication device provided in an embodiment of the present invention, such as... Figure 4 As shown, the voltage conversion module 24 also includes a second voltage conversion unit 242, which is electrically connected to the first voltage input / output terminal E4 and the power output terminal E3 respectively; the second voltage conversion unit 242 is used to convert the first voltage signal into a second voltage signal and transmit it to the power output terminal E3.

[0047] The second voltage conversion unit 242 may include a boost converter and / or a buck converter, etc. The second voltage signal may be a fixed value or a non-fixed value. Optionally, the second voltage signal may be the rated voltage of the walkie-talkie 10. For example, the second voltage signal is 5V, which can be set according to actual needs and is not specifically limited here.

[0048] Specifically, by setting a second voltage conversion unit 242, the first voltage signal provided by the first voltage input / output terminal E4 is boosted or bucked to be converted into the power supply voltage required by the walkie-talkie 10, and then transmitted to the walkie-talkie 10 through the power output terminal E3 and the power input terminal E1, thereby improving the safety and reliability of power supply.

[0049] Optional, Figure 5 This is a schematic diagram of the structure of a communication device provided in an embodiment of the present invention, such as... Figure 5 As shown, the first voltage conversion unit 241 includes a boost subunit 2411 and a first buck subunit 2412; both the boost subunit 2411 and the first buck subunit 2412 are used to output a first voltage signal.

[0050] The boost subunit 2411 may include a boost circuit composed of inductors, capacitors and switching transistors, etc., and the first buck subunit 2412 may include a buck circuit composed of inductors, capacitors and switching transistors, etc. Based on the fact that the boost subunit 2411 can achieve voltage boosting and the first buck subunit 2412 can achieve voltage bucking, the specific structures of the boost subunit 2411 and the first buck subunit 2412 can be set according to actual needs, and no specific limitation is made here.

[0051] Specifically, when the voltage signal at the power input terminal E2 is greater than the first voltage signal, the first buck subunit 2412 can be controlled to operate, converting the higher voltage signal into the first voltage signal and transmitting it to the first voltage input / output terminal E4. When the voltage signal at the power input terminal E2 is less than the first voltage signal, the boost subunit 2411 can be controlled to operate, converting the lower voltage signal into the first voltage signal and transmitting it to the first voltage input / output terminal E4. Thus, by configuring the first voltage conversion unit 241 to include both the boost subunit 2411 and the first buck subunit 2412, the first voltage conversion unit 241 can stably output the first voltage signal, improving the stability of the voltage signal at the first voltage input terminal E4.

[0052] Optional, see reference Figure 4 The second voltage conversion unit 242 includes at least a second step-down subunit 2422.

[0053] The second step-down subunit 2422 may include a step-down circuit composed of devices such as inductors, capacitors and switching transistors. Based on the fact that the second step-down subunit 2422 can achieve step-down, the specific structure of the second step-down subunit 2422 can be set according to actual needs, and no specific limitation is made here.

[0054] Specifically, the power supply voltage signal of the walkie-talkie 10 is less than the first voltage signal provided by the energy storage module 23 to the first voltage input / output terminal E4. By setting the second step-down subunit 2422, the first voltage provided by the first voltage input / output terminal E4 can be stepped down and converted into the power supply voltage required by the walkie-talkie 10, thereby improving the charging compatibility between the photovoltaic base station backpack 20 and the walkie-talkie 10 or other external communication devices.

[0055] Optional, Figure 6 This is a side view of a communication device provided in an embodiment of the present invention, as shown in the figure. Figure 6 As shown, the photovoltaic module 22 includes multiple detachable photovoltaic panels 220.

[0056] The number of detachable photovoltaic panels 220 can be set according to actual needs. For example, the photovoltaic module 22 includes 6 detachable photovoltaic panels 220, but it can also be other types, which are not specifically limited here.

[0057] Specifically, the detachable photovoltaic panel 220 can be fixed to the photovoltaic base station backpack 20 by screws or other fixing methods. The screws can be unscrewed to detach the photovoltaic panel 220 from the photovoltaic base station backpack 20. Other detachable methods can also be used for the detachable photovoltaic panel 220. By configuring the photovoltaic module 22 to include multiple detachable photovoltaic panels 220, if any one of the detachable photovoltaic panels 220 fails or becomes unusable, the faulty detachable photovoltaic panel 220 can be removed and replaced with a new one, improving replacement convenience and ensuring that the photovoltaic module 22 can continuously and stably provide power.

[0058] Optional, Figure 7 This is a schematic diagram of another communication device provided in an embodiment of the present invention, such as... Figure 7 As shown, the photovoltaic base station backpack 20 also includes a control module 25, which is at least connected to the energy storage module 23. The control module 25 is used to obtain the remaining power of the energy storage module 23 and control the charging and discharging state of the energy storage module 23 according to the remaining power.

[0059] Specifically, the control module 25 is electrically connected to the energy storage module 23 to obtain the remaining power of the energy storage module 23. This remaining power is compared with an upper and lower power limit. If the remaining power of the energy storage module 23 is greater than or equal to the lower power limit and less than the upper power limit, it is determined that the energy storage module 23 can discharge to the outside or be charged by the outside. In this case, the energy storage module 23 can be controlled to be in a charging or discharging state. If the remaining power is less than the lower power limit, it is determined that the energy storage module 23 has a low power level, and it can be controlled to be in a charging state to increase its remaining power. If the remaining power is greater than or equal to the upper power limit, it is determined that the energy storage module 23 has an excessively high power level. Continuing to provide electrical signals to the energy storage module 23 may lead to malfunctions, so in this case, the energy storage module 23 can be controlled to be in a discharging state to improve its operational safety.

[0060] It should be noted that the control module 23 can also acquire parameters such as the current charging current, current charging voltage, current discharging current, or current operating temperature of the energy storage module 23, so that when the operating parameters of the energy storage module 23 indicate that the energy storage module 23 is malfunctioning, it can promptly control the energy storage module 23 to stop charging and protect the photovoltaic base station backpack 20.

[0061] Optional, Figure 8 This is a schematic diagram of the structure of another communication device provided in an embodiment of the present invention, such as... Figure 8 As shown, the communication device also includes a switch module 26; the switch module 26 is electrically connected to the energy storage module 23 and the voltage conversion module 24 respectively; the control module 25 is used to control the on / off state of the switch module 26.

[0062] The switching module 26 includes switching devices such as transistors, which can be configured according to actual needs, and no specific limitations are made here.

[0063] Specifically, the control module 25 is electrically connected to both the energy storage module 23 and the voltage conversion module 24. When the energy storage module 23 needs charging or discharging, the control module 25 keeps the switch module 26 in a conducting state, allowing the voltage conversion module 24 to receive electrical energy from the energy storage module 23 via the switch module 26. Alternatively, the voltage conversion module 24 can convert the electrical signal provided by the power input terminal E2 and transmit it to the energy storage module 23 via the switch module 26. The control module 25 can acquire operating parameters of the energy storage module 23, such as its current operating voltage, current operating current, or current operating temperature. When the control module 25 determines that the energy storage module 23 is malfunctioning based on these parameters, it can control the switch module 26 to be in a disconnected state, preventing the energy storage module 23 from charging or discharging. This protects the energy storage module 23 and the photovoltaic base station backpack 20, improving the safety of the communication equipment.

[0064] Optional, Figure 9 This is a schematic diagram of another communication device provided in an embodiment of the present invention, such as... Figure 9 As shown, the control module 25 is connected to the voltage conversion module 24. The control module 25 is used to control the working mode of the voltage conversion module 24 according to the power signal at the power input terminal E2.

[0065] The operating modes include boost mode and buck mode.

[0066] Specifically, the control module 25 can acquire the power signal input at the power input terminal E2. The control module 25 can compare the power signal with a first voltage signal. When the power signal is greater than the first voltage signal, the control module 25 can control the voltage conversion module 24 to be in buck mode, enabling the voltage conversion module 24 to convert the power signal down to the first voltage signal. Conversely, the control module 25 can also compare the power signal with the first voltage signal. When the power signal is less than the first voltage signal, the control module 25 can control the voltage conversion module 24 to be in boost mode, enabling the voltage conversion module 24 to boost the power signal to the first voltage signal. In this way, the control module 25 can precisely control the operating mode of the voltage conversion module 24 according to the magnitude of the power signal, allowing the voltage conversion module 24 to stably output the first voltage signal.
