[0004] Problems identified with existing technologies: Maritime and outdoor operating environments are complex, often facing challenges such as rain, salt spray, and vibration. Existing technologies are insufficient in terms of waterproofing, salt spray resistance, and vibration resistance, making the lifespan of equipment susceptible to environmental impacts. Summary of the Invention

[0005] To address the above technical issues, this invention provides an EGC information receiving and display system based on the BeiDou Navigation Satellite System, characterized by comprising a protective structure and a main structure, wherein the main structure is disposed within the protective structure, and the protective structure and the main structure are connected by bolts and nuts.

[0006] The protective structure comprises a base, a waterproof platform, a visible housing, and a salt mist removal component. The waterproof platform is located on top of the base, and the base is connected to the waterproof platform. A groove is formed on the top of the base, and the visible housing is installed within this groove. The salt mist removal component is located on top of the visible housing and is sealed to the salt mist removal component. The salt mist removal component comprises a connecting frame, a container, a sealing cover, an activated carbon adsorption block, and a filter. The container is housed within the connecting frame and is sealed to the connecting frame. A sealing cover is located on the top of the container, and the container is connected to the sealing cover. A filter is installed at the bottom of the container, and an activated carbon adsorption block is placed inside the container. A sealing strip is provided in the groove on top of the base to ensure the airtightness of the connection between the base and the visible housing.

[0007] The main structure consists of an integrated shell, shock-absorbing pads, a BeiDou dual-mode signal receiving unit, a BeiDou navigation antenna, a data buffer, a data processing unit, a display unit, and a control panel. The bottom of the integrated shell is fitted with shock-absorbing pads, which are connected to the shell via bolts and nuts. The BeiDou dual-mode signal receiving unit is fixedly installed on one side of the integrated shell using screws. This unit has a dedicated signal interface for interfacing with the BeiDou navigation antenna extending outside the shell. A data buffer is positioned parallel to the BeiDou dual-mode signal receiving unit and connected to it via a data cable. A display unit is embedded on the other side of the integrated shell, connected to the data buffer via a data cable. A data processing unit is also located in the center of the integrated shell, electrically connected to the BeiDou dual-mode signal receiving unit, the data buffer, and the display unit. A control panel is located on one side of the display unit, electrically connected to it via wires.

[0008] The beneficial effects of this invention are as follows: This invention improves the protective structure, which consists of a base, a waterproof platform, a visible housing, and a salt spray removal component. The waterproof platform above the base prevents rainwater and waves from seeping in through the gaps in the base. The recessed installation of the base groove and the embedded installation of the visible housing, combined with the sealing process, further blocks the liquid intrusion path and prevents short circuits in the internal circuitry due to moisture. The sealed design of the connecting frame and the container box prevents the activated carbon adsorption block from becoming damp and failing. The bottom filter ensures air circulation inside the equipment, so that when the air containing salt spray flows through the activated carbon, the salt particles are efficiently adsorbed, preventing salt spray from corroding core components such as the Beidou dual-mode signal receiving unit and the data processing unit, and significantly reducing the component damage rate in high-salt-spray marine environments.

[0009] This invention improves the main structure, which consists of an integrated shell, shock-absorbing feet, a Beidou dual-mode signal receiving unit, a data buffer, a display unit, and a control panel. The bottom shock-absorbing feet can effectively buffer the vibration during ship rocking and outdoor handling, preventing data cable interfaces from falling off or components from loosening due to vibration, thus ensuring the accuracy of Beidou positioning and information reception. For example, in rough seas, it can reduce data processing errors caused by vibration. The Beidou dual-mode signal receiving unit has a reserved dedicated interface that can quickly connect to an external navigation antenna, enhancing signal reception sensitivity in complex terrain. The data buffer can temporarily store batch information such as navigation warnings and weather data, preventing information loss caused by excessive instantaneous load on the data processing unit.

Detailed Implementation Example 1

[0012] This invention provides an EGC information receiving and display system based on the BeiDou Navigation Satellite System. The protective structure comprises a base 1, a waterproof platform 2, a visible housing 3, and a salt mist removal component 4. The main structure comprises an integrated shell 5, shock-absorbing feet 6, a BeiDou dual-mode signal receiving unit 7, a BeiDou navigation antenna 10, a data buffer 8, a data processing unit, a display unit 9, and a control panel 11. A waterproof platform 2 is provided above the base 1, and the base 1 is connected to the waterproof platform 2. A groove is opened on the top of the base 1, and the visible housing 3 is installed in the groove of the base 1. A salt mist removal component 4 is provided above the visible housing 3, and the visible housing 3 is sealed to the salt mist removal component 4. The bottom of the integrated housing 5 is equipped with shock-absorbing pads 6, which are connected to the integrated housing 5 and the shock-absorbing pads 6 by bolts and nuts. A Beidou dual-mode signal receiving unit 7 is fixedly installed on one side of the integrated housing 5 by screws. This unit has a reserved dedicated signal interface, which can be connected to the Beidou navigation antenna 10 extending to the outside of the integrated housing 5. A data buffer 8 is arranged parallel to the side of the Beidou dual-mode signal receiving unit 7, and the Beidou dual-mode signal receiving unit 7 and the data buffer 8 are connected by a data cable. A display unit 9 is embedded on the other side of the integrated housing 5, and the data buffer 8 is connected to the display unit 9 by a data cable. A data processing unit is also provided in the center of the integrated housing 5. The data processing unit is electrically connected to the Beidou dual-mode signal receiving unit 7, the data buffer 8, and the display unit 9. A control panel 11 is provided on one side of the display unit 9, and the display unit 9 and the control panel 11 are electrically connected by wires. Example 2

[0013] When using this invention in a maritime navigation scenario, the operator first fixes the device base 1 to the edge of the ship's cockpit control panel with bolts, then opens the visible housing 3 and starts the device through the control panel 11. The Beidou dual-mode signal receiving unit 7 will automatically connect to the external Beidou navigation antenna 10 and quickly acquire Beidou satellite signals. At this time, the data processing unit will receive EGC information sent by the satellite in real time, such as navigation warnings and channel prohibition notices. If a sudden weather warning is encountered, the display unit 9 will trigger an audible and visual alarm and cache the information to the data buffer 8 to prevent data interruption due to instantaneous ship turbulence. In outdoor emergency rescue scenarios, rescuers can carry the device to the work area. The shock-absorbing foot pads 6 at the bottom can buffer the bumps and ground vibrations during transportation and prevent the data cable interface inside the integrated shell 5 from falling off. In areas with weak signals such as mountains and forests, the reserved dedicated antenna interface can also be replaced with a high-gain Beidou navigation antenna 10 to improve signal reception sensitivity. At this time, the display unit 9 will display key information such as the rescue route and the location of the trapped person in large font, so that rescuers can read it quickly. In daily use, staff need to regularly maintain the salt mist removal component 4, open the sealing cover 403 on the top of the container 402, take out the damp activated carbon adsorption block inside and replace it with a new one, and clean the dust at the bottom filter 404 at the same time to ensure that when the air inside the equipment is circulating, the air containing salt mist can fully contact the activated carbon, continuously blocking the corrosion of the Beidou dual-mode signal receiving unit 7 and the data processing unit by the salt mist. At the same time, check the sealing strip in the groove of the base 1. If it is aging, it can be replaced in time to ensure the airtightness of the visible shell 3 and the base 1, and further extend the service life of the equipment in complex environments.
