[0017] The following will be combined with the attached embodiment of the present utility model Figure 1-5 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example:

[0019] like Figures 1 to 5 As shown, the utility model discloses a Beidou positioning beacon based on low-orbit satellite communication, including a Beidou positioning module 1, a low-orbit satellite communication module 2, a data acquisition and processing control module 3, a power supply mechanism and a beacon light 5, the beacon light 5 includes an LED 51, an LED driving module 52 and an optical lens assembly 53, and the power supply mechanism includes a power management module 41, a charge and discharge management unit 42, a solar panel 43 and a battery 44, in addition, a lens cleaning system for cleaning the optical lens assembly 53 is provided on the beacon light 5.

[0020] Among them, the Beidou positioning module 1 is used to receive Beidou satellite signals in real time and generate accurate positioning data (longitude, latitude, altitude, etc.) of the navigation equipment, and transmit the data to the data acquisition and processing control module 3. The low-orbit satellite communication module 2 is used to conduct two-way data communication with the ground segment platform through the low-orbit satellite to realize the uploading of positioning data and the issuance of control instructions. Specifically: 1. Data upload: upload the positioning data and equipment status information (such as power supply and cleaning system working status) of the Beidou positioning module 1 to the ground platform in real time; 2. Command reception: receive control instructions issued by the ground platform (such as adjusting the brightness of LED51, starting the lens cleaning system, querying the equipment status, etc.).

[0021] In the utility model, the data acquisition and processing control module 3 is electrically connected to the Beidou positioning module 1 and the low-orbit satellite communication module 2, and is used to parse positioning data, store information and execute control instructions, specifically: 1. Data parsing and storage: parsing Beidou positioning data and equipment status data, and storing key information (such as historical positioning records, cleaning system operation logs); 2. Instruction execution: according to the ground platform instructions, controlling the LED drive module 52 to adjust the brightness / flashing mode of LED51, or triggering the lens cleaning system to work.

[0022] The power supply mechanism is used to supply power to each module, and its specific functions are: 1. Solar power supply: The solar panel 43 converts light energy into electrical energy, and charges the battery 44 through the charge and discharge management unit 42. 2. Battery 44 power supply: In the absence of light, the battery 44 provides continuous power for the device, and the power management module 41 dynamically adjusts the power supply priority (such as giving priority to Beidou positioning and communication modules).

[0023] Furthermore, the LED driving module 52 is controlled by the data acquisition and processing control module 3, and is used to adjust the brightness and flashing mode of LED 51 to ensure that a high-visibility navigation signal is provided in bad weather or at night. The optical lens 531 is a Fresnel lens, which converts the light source of LED 51 into parallel light through the lens to ensure the range of the beacon light 5. The optical lens 531 can better emit the light of LED 51, thereby improving the recognition distance and accuracy of the beacon light 5.

[0024] In the present invention, the optical lens assembly 53 specifically includes an optical lens 531 and an outer cover 532, and the optical lens 531 and the outer cover 532 are annular. In addition, the navigation light 5 also includes a base 54, an upper ring seat 55 and a top cover 56. The upper and lower ends of the optical lens 531 and the outer cover 532 are respectively connected to the upper ring seat 55 and the base 54 by bonding, and the outer cover 532 is sleeved on the outside of the optical lens 531. The LED 51 is installed on the base 54 and is located in the optical lens 531. The seat 55 is provided with a maintenance opening 551 leading to the inner side of the optical lens 531, and one side of the top cover 56 is hinged to the upper end of the upper ring seat 55, a locking screw 57 is provided on the other side of the top cover 56, and a threaded hole 552 for threaded engagement of the locking screw 57 is opened on the upper ring seat 55, and the top cover 56 is used to close the maintenance opening 551, and the top cover 56 is connected to the upper ring seat 55 by hinge and locking screw 57. The maintenance opening 551 facilitates maintenance personnel to quickly replace LED 51, thereby reducing the difficulty of maintenance.

[0025] In the utility model, the lens cleaning system specifically includes an air blowing ring 6, and the base 54 is provided with an installation countersunk 541 at the lower edge of the outer cover 532, and the air blowing ring 6 is located in the installation countersunk 541. Such a mounting structure is firm and reliable and will not block the optical lens assembly 53. The utility model is provided with an annular air distribution channel 61 and an annular air outlet cavity 62 in the air blowing ring 6, wherein the air outlet cavity 62 is located on the upper side of the air distribution channel 61, and a partition plate 63 is provided between the air outlet cavity 62 and the air distribution channel 61, and a plurality of air ports 631 are circumferentially provided on the partition plate 63, and an air inlet nozzle 64 penetrating into the air distribution channel 61 is fixedly connected to the side wall of the base 54, and an annular air outlet 65 is provided on the inner side of the upper end of the air blowing ring 6, and the air outlet 65 is communicated with the air outlet cavity 62. The air distribution channel 61 and the air outlet cavity 62 of the blowing ring 6 ensure uniform distribution of the air flow to avoid local cleaning dead corners. After the gas enters the air outlet cavity 62 through the air port 631, it is blown from the air outlet 65 to the surface of the outer cover 532 to form a directional airflow to efficiently remove attachments.

[0026] Furthermore, the air inlet 631 is located at a position close to the outer side of the partition 63, and the air inlet 631 is staggered with the air outlet 65 to prevent the airflow from directly impacting the lens surface and causing the accumulation of attachments. The air inlet 631 and the air outlet 65 are staggered so that the gas reaching the outlet cavity 62 from the air inlet 631 can be blown from the air outlet 65 to the outer cover 532 more evenly, ensuring that the airflow flows evenly along the surface of the outer cover 532. In addition, the blowing direction of the air outlet 65 forms an angle of 15-30° with the surface of the outer cover 532, and the airflow direction forms an angle with the surface of the outer cover 532, using the shear force of the airflow to efficiently peel off the salt crystals and dust, while reducing the direct impact damage to the lens surface. In addition, the upper ring seat 55 is provided with an airflow guiding arc surface 553 on one side facing the blowing ring 6, which is used to guide the airflow to disperse outward when it reaches the position of the upper ring seat 55, which is conducive to the dispersion of the blown salt crystals and dust, and also avoids the airflow directly hitting the blowing ring 6 for a long time. It should also be noted that the air inlet nozzle 64 is connected to an air pump through a hose (not shown in the figure, the air pump is existing technology, and the specific structural description will not be given). The air pump is fixedly installed on the navigation mark and powered by a power supply mechanism. The air pump inputs compressed air into the air equalization channel 61 through the air inlet nozzle 64, and the data acquisition and processing module automatically triggers the air pump to start working at a preset time (such as every 6 hours or 12 hours).

[0027] It should be noted that: the functions to be achieved by each hardware (Beidou positioning module 1, low-orbit satellite communication module 2, data acquisition and processing control module 3, power supply mechanism and navigation light 5) in the utility model are supported by a large number of mature technologies. The essence of the utility model is to optimize the combination of existing hardware and its connection method for specific application scenarios to adapt to the cleaning work of the lens cleaning system.

[0028] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
