Description

Technical Field

[0001] This invention relates to the field of emergency broadcasting technology, specifically to a highly reliable emergency broadcasting response terminal. Background Technology

[0002] Emergency broadcast and response terminals are communication systems used to disseminate emergency information to the public, specific areas, and specific groups of people through broadcast television transmission networks and other information networks in the event of major natural disasters, emergencies, or threats to public safety. For example, there is a highly reliable integrated emergency broadcast terminal with announcement number CN222169823U. Because emergency broadcast and response terminals are installed outdoors, they are susceptible to internal circuit short circuits, poor heat dissipation, and performance instability due to heavy rain, high temperatures, and dust accumulation, thus reducing the reliability of existing emergency broadcast and response terminals.

[0003] To improve the reliability of emergency broadcast response terminals, existing technologies have made improvements to rain protection, heat dissipation, and dust removal. For example, CN116961807A discloses a structural design for an emergency and public broadcast terminal that is rainproof and earthquake-resistant, which uses a rain shield for rain protection; CN220798290U discloses a new type of emergency broadcast adapter that uses a negative pressure pump and a dust removal pipe to cool and remove dust from the adapter's internal components; and CN115103248B discloses a multi-domain wireless broadcast multicast loudspeaker based on Internet control, which uses fan blades to dissipate heat from the inside of the loudspeaker body, while the rotation of the fan blades works in sync with the adsorption components to adsorb dust entering the ventilation channel.

[0004] In summary, the existing technologies mentioned above cannot simultaneously provide rainproof, heat dissipation, and dust removal functions, resulting in insufficient reliability of existing emergency broadcast response terminals. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a highly reliable emergency broadcast and response terminal, which solves the problem of insufficient reliability in existing emergency broadcast and response terminals.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: A highly reliable emergency broadcast response terminal is provided, comprising: The terminal body includes a control box mounted on the pole. The control box is connected to an external communication device and electrically connected to a speaker assembly mounted on the pole. Both the speaker assembly and the control box are provided with vents and multiple heat dissipation holes. Rain and sun protection assembly includes a support plate set on the top of the control box, an inflatable folding protective cover for covering the control box is set on the bottom surface of the support plate, the inflatable folding protective cover is provided with an inflation port and an deflation port, the inflation port and the deflation port are respectively connected to an inflation solenoid valve and a deflation solenoid valve, and both the inflation solenoid valve and the deflation solenoid valve are electrically connected to the control box. A dust removal and heat dissipation assembly includes an air pipe connected to a venting solenoid valve. The air pipe includes at least one air outlet, each air outlet being connected to a vent hole of a horn assembly or control box. Each vent hole is used to discharge heat and dust from the horn assembly or control box through the heat dissipation hole. The air source component is connected to the inflation solenoid valve and is used to inflate the inflatable folding protective cover, changing the inflatable folding protective cover from a folded state to an unfolded state.

[0007] The working principle of this solution is as follows: external communication equipment transmits broadcast signals to the control box, which processes the signals and broadcasts them through the speaker assembly. For rain and sun protection, the inflatable folding protective cover has both a folded and an unfolded state. The control box opens the inflation solenoid valve to inflate the cover with gas from the gas source assembly, switching it from the folded to the unfolded state. In the unfolded state, the cover protects the control box from both heavy rain and direct sunlight, reducing heat generation. When the rain stops or the light is dim, the control box opens the venting solenoid valve to release gas from the cover into the air pipe. This switches the cover from the unfolded to the folded state, exposing the control box and ensuring proper heat dissipation. Simultaneously, the gas from the cover enters the speaker assembly and the control box through the air pipe and flows out through the ventilation holes. This gas flow not only removes heat from the speaker assembly and control box but also blows away dust from the ventilation holes, achieving a dust removal function. In summary, this solution combines rainproof, heat dissipation, and dust removal functions, improving the reliability of existing emergency broadcast response terminals.

[0008] The beneficial effects of the rain and sun protection components are as follows: the support plate provides support for the inflatable folding protective cover while also protecting the top of the control box. The inflatable folding protective cover not only ensures a balance between protection and heat dissipation for the control box by switching between its unfolded and folded states, but also acts as a gas pressure regulator for the air source component. The folding and resetting force of the protective cover itself provides a relatively stable pressure for the gas, allowing the air pipe to discharge gas steadily. This prevents damage to the internal electrical components of the speaker assembly and control box when the gas enters through the vent. This is especially important for the speaker assembly, whose voice coil and diaphragm are highly precise structures; dust accumulation can affect sound quality. Cleaning the voice coil and diaphragm requires a stable airflow. Therefore, this solution utilizes the characteristics of the inflatable folding protective cover to remove dust from the speaker assembly using airflow while avoiding damage, thus improving the long-term stability of the speaker assembly in outdoor environments.

[0009] Furthermore, the terminal also includes solar panels and satellite communication components. The solar panels include an equipment compartment located at the bottom of the pole, housing a battery pack electrically connected to a photovoltaic controller and a control box. The photovoltaic controller is electrically connected to solar panels fixed to the pole. The satellite communication components include a BeiDou signal receiver fixed to the pole, electrically connected to the control box. The solar panels utilize solar energy, making them suitable for outdoor environments without external power sources and improving power reliability. The satellite communication components enable the reception of emergency signals even when traditional communication networks fail due to disasters, enhancing communication reliability.

[0010] Furthermore, the terminal body also includes a monitoring component, which includes a meteorological monitoring device and a monitor, both electrically connected to the control box. The meteorological monitoring device includes a rain gauge, a weather louver, and a wind speed sensor mounted on the pole, while the monitor is fixed to the pole via a monitoring mounting arm. The meteorological monitoring device can monitor the local weather, allowing the control box to open or close the inflatable folding protective cover according to the current weather conditions.

[0011] Furthermore, a dust-removing brush is installed on the inner wall of the inflatable folding protective cover near the unfolded end. This brush is used to remove dust from multiple heat dissipation holes located on the side wall of the control box. The inflatable folding protective cover utilizes the switching process between its unfolded and folded states to move the dust-removing brush up and down, further improving dust removal capabilities without the need for additional drive structures.

[0012] Furthermore, the inner wall of the inflatable folding protective cover is equipped with an elastic interlayer bag for condensate collection. The opening of the elastic interlayer bag is connected to a channel in a heat dissipation vent on the support plate, where condensate is contained. The cooling principle of the condensate is as follows: when the inflatable folding protective cover is folded, the elastic interlayer bag contracts and compresses, and the condensate is located in the heat dissipation vent; when the inflatable folding protective cover is unfolded, the elastic interlayer bag unfolds simultaneously, and the condensate in the heat dissipation vent enters the elastic interlayer bag by gravity. The condensate cools the gas in the inflatable folding protective cover, and the cooled gas can be used to blow air to cool the horn assembly and control box. The circulation process of the condensate relies solely on the folding and contraction of the inflatable folding protective cover and its own gravity, further improving the heat dissipation capacity without the need for an additional drive structure.

[0013] Furthermore, the inflatable folding protective cover is a rectangular telescopic folding airbag, a circular telescopic folding airbag, or a folding inflatable cover; each side wall of the rectangular telescopic folding airbag includes multiple interconnected air column bags; the wall of the circular telescopic folding airbag includes multiple interconnected circular air bags; the folding inflatable cover includes a circular inflatable cover body with a circular cross-section or a rectangular inflatable cover body with a rectangular cross-section; the wall of the circular inflatable cover body is spirally coiled with an elastic skeleton for folding the inflatable cover body; the wall of the rectangular inflatable cover body is provided with multiple rectangular skeletons at equal intervals, and adjacent rectangular skeletons are elastically connected; wherein, the air column bags, circular air bags, and inflatable cover body are all made of elastic light-blocking material; the circular inflatable cover body and the rectangular inflatable cover body are made of flexible light-blocking material. The rectangular telescopic folding airbag and the circular telescopic folding airbag are folded using the contraction elasticity of the air column bags and the circular air bags; the circular inflatable cover body and the rectangular inflatable cover body are contracted using the elasticity between the elastic skeleton and the rectangular skeleton, respectively.

[0014] Furthermore, the gas source assembly includes a mounting housing mounted on a support plate. The mounting housing has an air intake port, and inside the housing is a diaphragm-type air pump, a piston-type air pump, or a compressed gas cylinder, which is connected to an air filling solenoid valve. Both the diaphragm-type and piston-type air pumps are electrically connected to the control box. The diaphragm-type and piston-type air pumps can draw in external gas through the air intake port. Although the compressed gas cylinder needs to be replaced periodically, the temperature of the gas released during rapid gas release is lower than the ambient temperature. Additionally, the compressed gas cylinder can contain selectable gases, such as carbon dioxide. Introducing carbon dioxide into the horn assembly and control box can reduce or prevent internal circuit short circuits and fires.

[0015] Furthermore, a dust cover is provided at the air intake on the mounting housing, and the air intake is oriented towards the heat dissipation radiator. The orientation of the air intake facilitates the intake of air by the diaphragm-type or piston-type air pump, allowing the intake air to flow through the heat dissipation radiator and accelerating the dissipation of condensate in the heat dissipation radiator.

[0016] Furthermore, a vertically upward connecting rod is installed on the outer wall of the unfolded end of the inflatable folding protective cover. The free end of the connecting rod passes through the support plate and is fixed to a dust removal brush, which is used to remove dust from the dust cover. The dust removal brush is driven by the folding and telescopic capabilities of the inflatable folding protective cover, achieving dust removal from the dust cover without the need for an additional drive structure. This ensures smooth air intake for the air source component and enables the air source component to have a self-cleaning function.

[0017] Furthermore, the dust removal and heat dissipation assembly also includes a dust removal mechanism, which includes a self-resetting pneumatic dust removal component located at the heat dissipation hole of the control box. The air inlet of the self-resetting pneumatic dust removal component is connected to the venting solenoid valve. The self-resetting pneumatic dust removal component has an initial state and a working state. Opening the venting solenoid valve allows the gas in the inflatable folding protective cover to be introduced into the self-resetting pneumatic dust removal component, switching the self-resetting pneumatic dust removal component from the initial state to the working state, and sweeping away the dust on the heat dissipation hole of the control box during the switching process. Considering the limitations of airflow dust removal and the fact that the control box's heat dissipation holes are not located on the side wall, this solution adds a self-resetting pneumatic dust removal component at the heat dissipation hole. A multi-position, multi-way solenoid valve controls the gas flow into the self-resetting pneumatic dust removal component, enabling it to switch from its initial state to its working state. After releasing the gas from the component, it uses its self-resetting function to switch back to its initial state. This self-resetting pneumatic dust removal component not only complements airflow dust removal but also reduces energy consumption due to its self-resetting characteristic.

[0019] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0020] Existing technologies cannot simultaneously provide rain protection, heat dissipation, and dust removal functions, resulting in insufficient reliability of existing emergency broadcast response terminals. To address this issue, this embodiment provides a highly reliable emergency broadcast response terminal, comprising a terminal body 100, a rain and sun protection component 200, a dust removal and heat dissipation component 300, and an air source component 400.

[0021] refer to Figure 1 The terminal body 100 includes a control box 11 mounted on a pole 12. The control box 11 is communicatively connected to an external communication device and electrically connected to a speaker assembly 13 mounted on the pole 12. The speaker assembly 13 includes at least one speaker. Each speaker and the control box 11 are provided with a vent hole and multiple heat dissipation holes communicating with the vent hole.

[0022] Preferably, but not limited to, for better convection, the vents in the horn and control box 11 are located on opposite sides of the multiple heat dissipation vents.

[0023] Rain and sun protection assembly 200 includes a support plate 21 disposed on the top of the control box 11, and an inflatable folding protective cover 22 for covering the control box 11 is disposed on the bottom surface of the support plate 21. (See reference) Figure 3 , Figure 4 and 7The inflatable folding protective cover 22 is equipped with an inflation port and an deflation port. The inflation port is connected to the inflation solenoid valve 221 via an air nozzle, and the deflation port is connected to the deflation solenoid valve 222. Both the inflation solenoid valve 221 and the deflation solenoid valve 222 are electrically connected to the control box 11. The inflatable folding protective cover 22 has a folded state and an unfolded state. The inflatable folding protective cover 22 is in the folded state when it is not inflated, and in the unfolded state after inflation, it covers the control box 11.

[0024] In this embodiment, the inflatable folding protective cover 22 is a rectangular telescopic folding airbag, a circular telescopic folding airbag, or a folding inflatable cover. Each sidewall of the rectangular telescopic folding airbag includes multiple interconnected air column bags; the wall of the circular telescopic folding airbag includes multiple interconnected circular air bags; the folding inflatable cover includes a circular inflatable cover body with a circular cross-section or a rectangular inflatable cover body with a rectangular cross-section; an elastic frame 226 for folding the inflatable cover body is spirally coiled on the wall of the circular inflatable cover body; multiple rectangular frames are equally spaced on the wall of the rectangular inflatable cover body, and adjacent rectangular frames are elastically connected by elastic ropes or springs; wherein, the air column bags, circular air bags, and inflatable cover body are all made of elastic light-blocking material; the circular inflatable cover body and the rectangular inflatable cover body are made of flexible light-blocking material. The rectangular telescopic folding airbag and the circular telescopic folding airbag are folded using the contraction elasticity of the air column bags and the circular air bags. The circular inflatable cover body and the rectangular inflatable cover body are contracted using the elastic force between the elastic frame 226 and the rectangular frame, respectively. In this embodiment, a circular inflatable cover is preferred, which has a simple structure and the elasticity of the elastic frame 226 is easy to control.

[0025] Dust removal and heat dissipation assembly 300, which includes an air pipe 31 connected to a venting solenoid valve 222, see reference. Figure 8 The air pipe 31 includes at least one air outlet, each air outlet being connected to a vent hole of the horn assembly 13 or the control box 11, and each vent hole being used to expel heat and dust from the horn assembly 13 or the control box 11 through a heat dissipation hole.

[0026] The air source assembly 400 is connected to the inflation solenoid valve 221 and is used to inflate the inflatable folding protective cover 22, changing the inflatable folding protective cover 22 from a folded state to an unfolded state.

[0027] In this embodiment, the gas source component 400 can be a compressed gas cylinder or a portable air pump. Although compressed gas cylinders need to be replaced periodically, the temperature of the gas released during rapid gas release is lower than the ambient temperature. Furthermore, the compressed gas cylinder can contain a selectable gas, such as carbon dioxide. Introducing carbon dioxide into the horn assembly 13 and the control box 11 can reduce or prevent internal circuit short circuits and fires. The air pump is either a diaphragm-type or piston-type air pump electrically connected to the control box 11. The air pump is installed in a mounting housing on the support plate 21, and the mounting housing has an air intake port. Both diaphragm-type and piston-type air pumps can draw in external gas through the air intake port.

[0028] The working principle of this embodiment is as follows: External communication equipment transmits broadcast signals to control box 11, which processes the signals and broadcasts them via speaker assembly 13. For rain and sun protection, the inflatable folding protective cover 22 has a folded state and an unfolded state. Control box 11 opens the inflation solenoid valve 221 to fill the inflatable folding protective cover 22 with gas from the air source assembly 400, switching it from the folded state to the unfolded state. In the unfolded state, the inflatable folding protective cover 22 covers the control box 11, preventing both heavy rain and direct sunlight, thus reducing heat generation in the control box 11. When the rain stops or the backlight is off, to improve heat dissipation, the control box 11 opens the venting solenoid valve 222, allowing gas from the inflatable folding protective cover 22 to enter the air pipe 31. At this time, the inflatable folding protective cover 22 switches from an unfolded state to a folded state, exposing the control box 11 and ensuring normal heat dissipation. Simultaneously, the gas from the inflatable folding protective cover 22 enters the speaker assembly 13 and the interior of the control box 11 through the air pipe 31 and flows out from the heat dissipation holes of the speaker assembly 13 and the control box 11. This gas flow not only removes internal heat from the speaker assembly 13 and the control box 11 but also blows away dust from the heat dissipation holes, achieving a dust removal function. Furthermore, this embodiment can simultaneously open the inflation solenoid valve 221 and the deflation solenoid valve 222 when necessary, bypassing the inflatable folding protective cover 22 to prioritize heat dissipation and prevent damage to the adapter in the control box 11 due to high temperatures. In summary, this solution combines rain protection, heat dissipation, and dust removal functions, improving the reliability of existing emergency broadcast response terminals.

[0029] The beneficial effects of the rain and sun protection component 200 are: the support plate 21 provides support for the inflatable folding protective cover 22 and also protects the top of the control box 11. The inflatable folding protective cover 22 not only ensures a balance between protection and heat dissipation for the control box 11 by switching between its unfolded and folded states, but also acts as a gas regulator for the air source assembly 400. The folding and resetting force of the cover provides a relatively stable pressure for the gas, allowing the air pipe 31 to stably discharge gas. This prevents damage to the internal electrical components of the speaker assembly 13 and control box 11 when the gas enters through the vent. This is especially important for the speaker assembly 13, whose voice coil and diaphragm are highly precise structures; dust accumulation can affect the speaker's sound quality. Cleaning the voice coil and diaphragm requires a stable airflow. Therefore, this solution utilizes the characteristics of the inflatable folding protective cover 22 to remove dust from the speaker assembly 13 using airflow while avoiding damage, thus improving the long-term stability of the speaker assembly 13 in outdoor environments.

[0030] As a further embodiment, to ensure the cleanliness of the inhaled gas, a dust cover is provided at the air intake on the mounting housing. A vertically upward connecting rod 223 is provided on the outer wall of the unfolded end of the inflatable folding protective cover 22. The free end of the connecting rod 223 passes through the through hole of the support plate 21 and is fixed to the dust removal brush 224. The dust removal brush 224 is used to remove dust from the dust cover. (Refer to...) Figure 4 and Figure 5 The dust removal brush 224 and the connecting rod 223 are fixedly arranged to form a T-shaped structure, and the mounting housing has a groove to accommodate the dust removal brush 224. The dust removal brush 224 is driven by the folding and telescopic capabilities of the inflatable folding protective cover 22, which achieves dust removal of the dust cover without the need for an additional drive structure, ensuring the smoothness of air intake when the air source assembly 400 draws in air, and realizing the self-cleaning function of the air source assembly 400.

[0031] As one embodiment, the control box 11 in this embodiment has multiple heat dissipation holes on both side walls. To further improve the cleaning ability of the heat dissipation holes, a dust removal brush is provided on the inner wall of the inflatable folding protective cover 22 near the unfolded end. The dust removal brush is used to remove dust from the multiple heat dissipation holes located on the side walls of the control box 11. The inflatable folding protective cover 22 uses the switching process between its unfolded and folded states to drive the dust removal brush to move up and down, further improving the dust removal ability without the need to add a drive structure.

[0032] As another embodiment, the multiple heat dissipation holes of the control box 11 in this embodiment can be set on the bottom. In order to improve the cleaning ability of the multiple heat dissipation holes on the bottom, the dust removal and heat dissipation assembly 300 also includes a dust sweeping mechanism. The dust sweeping mechanism includes a self-resetting pneumatic dust sweeping component 33 set at the heat dissipation holes of the control box 11. The air inlet of the self-resetting pneumatic dust sweeping component 33 is connected to the venting solenoid valve 222 through the drive air pipe 32. (Refer to...) Figure 8 .

[0033] The self-resetting pneumatic dust removal component 33 includes an initial state and a working state. Opening the venting solenoid valve 222 allows gas from the inflatable folded protective cover 22 to enter the self-resetting pneumatic dust removal component 33, switching it from the initial state to the working state. During this switching process, dust is removed from the heat dissipation holes of the control box 11. The multi-position, multi-way venting solenoid valve 222 controls the gas flow into the self-resetting pneumatic dust removal component 33, enabling it to switch from the initial state to the working state. After releasing the gas, the component uses its self-resetting function to switch back from the working state to the initial state. The self-resetting pneumatic dust removal component 33 not only complements airflow dust removal but also reduces energy consumption due to its self-resetting characteristic.

[0034] In this embodiment, the self-resetting pneumatic dust removal component 33 is a spring-driven self-resetting floating scraper, a spring-driven self-resetting rotating scraper, or a self-resetting flexible pneumatic arm. The spring-driven self-resetting floating scraper includes a first spring cylinder, with a movable scraper fixed to the moving end of the first spring cylinder. The first spring cylinder drives the movable scraper to move and scrape away dust from the heat dissipation holes. The spring-driven self-resetting floating scraper has a simple structure and is easy to install. The spring-driven self-resetting rotating scraper includes a rotating scraper hinged to the control box 11. The short arm of the rotating scraper is hinged to the moving end of a second spring cylinder. The second spring cylinder drives the short arm of the rotating scraper to rotate, thereby causing the long arm of the rotating scraper to scrape away dust from the heat dissipation holes. The spring-driven self-resetting rotating scraper has a large scraping range. The self-resetting flexible pneumatic arm has an initial state and a working state of curled and straightened, respectively. After gas is introduced, the self-resetting flexible pneumatic arm switches from the curled state to the straightened state. During the switching process, the self-resetting flexible pneumatic arm scrapes away dust from the heat dissipation holes. The self-resetting flexible pneumatic arm can achieve reset without the need for a cylinder, reducing costs. In this embodiment, a spring-resetting floating scraper is preferred. The spring-resetting floating scraper utilizes the restoring force of the first spring cylinder and, in conjunction with the venting solenoid valve 222, can further control the gas pressure entering the horn assembly.

[0035] As a further embodiment, to further improve heat dissipation capacity, the inner wall of the inflatable folding protective cover 22 is provided with an elastic interlayer bag 225 for accommodating condensate, as shown in the reference. Figure 6The opening of the elastic interlayer bag 225 is connected to a channel in the heat dissipation vent 23 located on the support plate 21, and condensate is contained in the heat dissipation vent 23. The cooling principle of the condensate is as follows: when the inflatable folded protective cover 22 is in the folded state, the elastic interlayer bag 225 contracts and compresses, and the condensate is located in the heat dissipation vent 23; when the inflatable folded protective cover 22 is in the unfolded state, the elastic interlayer bag 225 unfolds simultaneously, and the condensate in the heat dissipation vent 23 enters the elastic interlayer bag 225 by gravity. The condensate cools the gas in the inflatable folded protective cover 22, and the cooled gas is convenient for blowing air to cool the horn assembly 13 and the control box 11. The circulation process of the condensate relies only on the folding and contraction of the inflatable folded protective cover 22 and its own gravity, further improving the heat dissipation capacity without the need for an additional drive structure. At the same time, in order to accelerate the heat dissipation of the condensate in the heat dissipation vent 23, the air intake on the mounting shell of the air source assembly 400 is positioned facing the heat dissipation vent 23. The orientation of the air intake towards the heat dissipation vent 23 facilitates the air intake of the diaphragm-type or piston-type air pump to flow through the heat dissipation vent 23, thereby promoting heat dissipation.

[0036] As a further embodiment, to improve power supply reliability and communication reliability, the terminal body 100 may also include a solar panel and a satellite communication panel, as shown in the reference. Figure 2 The solar panel includes an equipment compartment located at the bottom of the pole 12, containing a battery pack electrically connected to a photovoltaic controller and a control box 11. The photovoltaic controller is electrically connected to a solar panel 14 fixed to the pole 12. The satellite communication component includes a BeiDou signal receiver fixed to the pole 12, which is electrically connected to the control box 11. The solar panel utilizes solar energy, making it suitable for outdoor environments without external power sources and improving power reliability. The satellite communication component can still receive emergency signals when traditional communication networks fail due to disasters, enhancing communication reliability.

[0037] As a further embodiment, the terminal body 100 also includes a monitoring component, which includes a meteorological monitoring device and a monitor, both electrically connected to the control box 11. The meteorological monitoring device includes a rain gauge 15, a weather louver 16, and a wind speed sensor 17 mounted on the pole 12. The monitor is fixed to the pole 12 via a monitoring mounting arm. The meteorological monitoring device can monitor the local weather, allowing the control box 11 to open or close the inflatable folding protective cover 22 according to the current weather conditions. The terminal body 100 may also include a waterproof display 18 fixed to the pole 12. The waterproof display 18 is used to display the data from the meteorological monitoring device, making it convenient for local residents to understand the weather conditions.

[0038] In summary, the beneficial effects of this solution are as follows: This solution's emergency broadcast and response terminal integrates rain and sun protection, dust removal and heat dissipation, energy supply, and intelligent monitoring functions, solving the reliability issues of existing terminals caused by heavy rain, high temperatures, and dust accumulation in outdoor environments. Specifically, the inflatable folding protective cover 22 achieves a balance between rain and sun protection and natural heat dissipation by switching between unfolded and folded states; simultaneously, the stable airflow when the protective cover deflates is guided into the terminal body 100 for dust removal and heat dissipation, avoiding damage to the sound-producing structure in the speaker; and combined with solar panels and satellite communication components, it ensures energy self-sufficiency and communication redundancy; furthermore, the monitoring components and self-resetting pneumatic dust removal component 33 further enhance the terminal's adaptability and self-cleaning capabilities, strengthening the long-term stability and reliability of the emergency broadcast and response terminal under complex outdoor conditions.
