[0020] The following describes the embodiments of the present invention through specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0022] See also Figures 1 to 4.

It can be applied to the communication coverage scenarios of the same type of cross-sea bridges or expressways. Through the overall networking, the multi-standard network coverage capability of the entire bridge deck can be achieved, providing a high-quality network service foundation for 5G applications such as smart transportation, smart ports, and smart logistics.

[0023] like Figures 1 to 3 As shown, in one embodiment, the present invention discloses an outdoor base station component for mobile communication of a cross-sea bridge, including a steel frame platform 12, an outdoor cabinet device 13 and two street light pole tower masts 14, wherein the steel frame platform 12 is installed between a first road surface 15 and a second road surface 16, wherein the lane directions of the first road surface 15 and the second road surface 16 are opposite, and both sides of the first road surface 15 and the second road surface 16 are provided with road crash barriers 17, and bridge guardrails 18 are installed above the road crash barriers 17, and the number of the street light pole tower masts 14 is two and they are close to the end of the steel frame platform 12, and are respectively installed on the two inner sides of the first road surface 15 and the second road surface 16. Prefabricated anchor bolts (not shown) are fixedly installed with the bridge guardrail 18. The outdoor cabinet equipment 13 is installed on the steel frame platform 12. The outdoor equipment 13 includes a supporting cabinet 5 and an equipment cabinet 6 installed on the steel frame platform 12. The equipment cabinet 6 is located between the supporting cabinet 5 and the street light pole tower mast 14. The equipment cabinet 6 is used to install communication equipment to realize bridge communication. The supporting cabinet 5 is used to power the equipment cabinet 6 and monitor the working status of the equipment cabinet 6. An antenna bracket 10 is installed on the street light pole tower mast 14. The communication equipment in the equipment cabinet 6 communicates with external equipment through the antenna installed on the antenna bracket 10.

[0024] In this embodiment, a steel frame platform 12 is installed between the first pavement 15 and the second pavement 16 of the bridge, and a matching cabinet 5 and an equipment cabinet 6 are respectively installed on the steel frame platform 12, so as to cooperate with the antenna installed on the antenna bracket 10 to communicate with external equipment, thereby realizing the networking communication of the bridge. The entire device is installed between the first pavement 15 and the second pavement 16. While ensuring the communication of the bridge, the safety of the construction process is greatly improved, and it is not easy to affect the road traffic of the bridge.

[0025] In some embodiments, the steel frame platform 12 includes a main beam steel plate assembly 1 installed between the first pavement 15 and the second pavement 16, a secondary beam 2 vertically connected to the road crash barrier 17 is installed at the bottom of the main beam steel plate assembly 1, a support foot 3 is installed at the bottom of the secondary beam 2, and guardrails 4 are installed at both ends of the main beam steel plate assembly 1. The guardrails 4 at both ends form a quadrilateral guardrail with the bridge guardrails 18 on both sides of the steel frame platform 12, and the matching cabinet 5 and the equipment cabinet 6 are both installed on the main beam steel plate assembly 1.

[0026] In this embodiment, the main beam steel plate assembly 1 is installed in the area between the first road surface 15 and the second road surface 16, and the secondary beam 2 is used to connect with the road crash barrier 17, so that the main beam steel plate assembly 1 and the road crash barrier 17 are stably connected, effectively ensuring the stability of the entire steel frame platform 12. On the other hand, since a quadrilateral guardrail is formed between the guardrails 4 at both ends of the main beam steel plate assembly 1 and the bridge guardrails 18 on both sides, when the operator installs or maintains the equipment of the supporting cabinet 5 and the equipment cabinet 6 on the steel frame platform 12, the safety of the operator can be guaranteed, and the construction is also convenient during installation, and it is not easy to affect the traffic of vehicles on the first road surface 15 and the second road surface 16.

[0027] Furthermore, the secondary beam 2, the road crash barrier 17 and the support legs 3 are all installed in a detachable manner, and the guardrail 4 is fixedly connected to the bridge guardrail 18 by bolts.

[0028] Since the secondary beam 2 is installed in a detachable manner with the road crash barrier 17 and the support leg 3, the installation and disassembly of the entire device is convenient, which is conducive to improving construction efficiency. The guardrail 4 is fixedly connected to the bridge guardrail 18 by bolts, so that the guardrail 4 and the bridge guardrail 18 are connected as a whole, while ensuring the stability of the guardrail 4, reducing the impact of the entire device on the bridge itself, and can reduce the impact of the bridge body on the supporting cabinet 5 in the outdoor cabinet equipment 13 and the base station communication equipment in the equipment cabinet 6 when it is in use and vibrates, ensuring the durability of the base station communication equipment.

[0029] It should be noted that the height of the bottom of the entire steel frame platform 12 is higher than the bottom height of the road crash barrier 17, which is convenient for installation, and the top height of the guardrail 4 is lower than the height of the bridge guardrail 18. While ensuring the protective effect, it will not affect the use of the bridge guardrail 18.

[0030] In some other embodiments, the street light pole mast 14 includes a support rod 9 and a bent rod 19, the bent rod 19 is connected to the top of the support rod 9, the bottom of the support rod 9 is fixed to the bridge deck by the anchor bolts, and is fixedly connected to the bridge guardrail 18 by bolt clamps, an antenna bracket 10 is installed on the top of the support rod 9, the interior of the support rod 9 is a hollow structure, and the bottom end of the support rod 9 and the position close to the antenna bracket 10 are respectively provided with a first threading hole (not shown in the figure) and a second threading hole (not shown in the figure), so that the cable can be passed through the first threading hole at the bottom into the support rod 9, and passed through the second threading hole to be connected to the antenna bracket 10.

[0031] In this embodiment, the street light pole mast 14 is a new street light pole formed on the basis of the original bridge deck street light. While playing the role of street lighting, it is used as an antenna to realize the transmission and reception of communication signals. Specifically, the bottom of the support rod 9 is fixedly installed with the bridge guardrail 18 through a bolt clamp, which is convenient for subsequent disassembly and maintenance. Since the antenna bracket 10 is installed on the top of the support rod 9, after the corresponding communication antenna is installed on the antenna bracket 10, when it is necessary to use optical fiber or cable connection, the optical fiber or cable to be connected is passed through the first threading hole at the bottom of the support rod 9, and passes through the second threading hole after passing through the inside of the support rod 9, thereby realizing the hidden installation of the optical fiber or cable, protecting the optical fiber or cable, and helping to extend the service life of the communication equipment.

[0032] Furthermore, a prefabricated lamp holder 11 for lighting is installed at one end of the bending rod 19 away from the supporting rod 9, and the prefabricated lamp holders 11 for lighting on both sides are close to the corresponding road surface to play a lighting role. A prefabricated grounding flat steel (not shown in the figure) is also installed at the bottom end of the supporting rod 9. The prefabricated grounding flat steel is used to provide an outdoor grounding terminal for external equipment.

[0033] Lighting is achieved through the prefabricated lamp holder 11 at the end of the support rod 9, and the prefabricated grounding flat steel at the bottom of the support rod 9 can provide an outdoor grounding terminal, which is convenient for grounding external equipment. There is no need to provide a separate grounding terminal, which is more convenient to use.

[0034] In some other embodiments, the number of the antenna brackets 10 installed on each of the support rods 9 is at least two, the antenna brackets 10 are used to install an active antenna AAU or a plate-shaped directional antenna, a lightning protection device (not shown) is installed on the bent rod 19, and the antenna brackets 10 are located within the lightning protection range of the lightning protection device.

[0035] The lightning protection device installed on the bent rod 19 is used to provide lightning protection for the antenna installed on the antenna bracket 10 to prevent the antenna from being damaged by lightning.

[0036] In some other embodiments, one of the antenna brackets 10 is equipped with two active antennas AAU facing the two ends of the first road surface 15 respectively, and the other antenna bracket 10 is equipped with two plate-shaped directional antennas facing the two ends of the second road surface 16 respectively. A baseband unit BBU is arranged inside the equipment cabinet 6, and a radio frequency remote unit RRU is installed on the guardrail 4. The radio frequency remote unit RRU is communicatively connected to the baseband unit BBU through optical fiber, and the baseband unit BBU is communicatively connected to the first antenna to realize 4G communication. A central unit and a distributed unit are also installed inside the equipment cabinet 6 to realize 5G communication through the central unit, the distributed unit and the second antenna. The first antenna is one of the active antenna AAU or the plate-shaped directional antenna, and the second antenna is the other of the active antenna AAU or the plate-shaped directional antenna. A GNNS antenna 7 is also installed on the side of the guardrail 4 close to the equipment cabinet 6, and the GNNS antenna 7 is used to transmit clock synchronization positioning signals.

[0037] In this embodiment, 4G communication is achieved through the baseband unit BBU installed inside the equipment cabinet 6, the radio remote unit RRU installed on the guardrail 4, and the first antenna installed on the antenna bracket 10, and 5G communication is achieved through the central unit, distributed unit and second antenna installed inside the equipment cabinet 6, so that the entire bridge road is covered with 4G and 5G signals, which can meet the communication needs of different types of users in actual communication and is more practical.

[0038] Furthermore, the positioning signal is received by the GNNS antenna 7 installed on the guardrail 4. Since the GNNS antenna 7 is installed outside the equipment cabinet 6, it has a better signal reception effect, which is beneficial to improving the accuracy of the received positioning signal.

[0039] It should be noted that the selection of the first antenna and the second antenna is not limited to the active antenna AAU or the plate-shaped directional antenna. Different antennas can also be selected for adaptation according to actual needs. This solution does not specifically limit this. The baseband unit BBU and radio remote unit RRU for 4G communication and the central unit and distributed unit for 5G communication can all adopt the contents of the existing technology. This solution does not involve improvements to the various units themselves, which will not be repeated here.
