[0029] In 5G applications in mining, base stations need to be connected to an industrial ring network for unified management. This means that base stations must be connected to industrial switches via optical cables during deployment, and then the switches will be used to connect them to the ring network. This network model results in high switching equipment costs, and the laying and splicing of a large number of optical cables also poses a great challenge to the complex underground environment.

Figure 1 As shown, this utility model embodiment provides a mining industrial-grade 5G base station controller, including: an explosion-proof housing 1, a baseband processing module 4, a transformer 24, and a switch module 5 disposed within the explosion-proof housing 1. The first part of the interface of the baseband processing module 4 is connected to the switch module 5 through an optical fiber 10. The switch module 5 is connected to an optical fiber quick-connect interface 25. The optical fiber quick-connect interface 25 is connected to an industrial ring network via an external optical cable.

The power input port of the transformer 24 is connected to a power quick-connect interface 8 through a power cord, thereby connecting to an external AC power supply.

[0035] This utility model provides a mining-grade industrial 5G base station controller. It houses the baseband processing module, transformer, and switch module within an explosion-proof enclosure. The first part of the baseband processing module's interface is connected to the switch module via optical fiber. The switch module is connected to a fiber optic quick-connect interface, which connects to an external optical cable in an industrial ring network, enabling communication between the industrial 5G base station controller and the 5G core network. The second part of the baseband processing module's interface is also connected to the fiber optic quick-connect interface, which connects to an external optical cable in a remote radio frequency unit. The power input ports of the baseband processing module and switch module are connected to the transformer's power output port via power lines. The transformer's power input port is connected to the power quick-connect interface via power lines, allowing access to external AC power. This utility model can connect to the core switch above ground and to the 5G base station below ground via the fiber optic quick-connect interface. Base station controllers can also be interconnected. An industrial ring network can be formed without the need for dedicated industrial switches. The control platform above ground can manage and control the baseband processing module system, avoiding the laying and splicing of large amounts of optical cable, saving construction and networking costs. The quick-connect interface design allows for plug-and-play wiring without opening the enclosure.

[0036] Since the core components are placed inside the explosion-proof enclosure 1, the issues of later installation and maintenance need to be considered.

[0037] Based on the above issues, refer to Figure 2 and Figure 3 , Figure 2 This is an exploded view of the installation structure of the baseband processing module provided in this embodiment of the utility model. Figure 3 An exploded view of the baseband processing module guide rail provided in an embodiment of this utility model, as shown below. Figure 2 and Figure 3As shown, in this embodiment of the invention, a baseband processing module guide rail 6 is fixed on the inner wall of the explosion-proof housing 1. A baseband processing module frame 2 is slidably connected to the baseband processing module guide rail 6. The baseband processing module 4 is fixed on the baseband processing module frame 2 so that the baseband processing module 4 can be pulled out or pushed into the explosion-proof housing 1.

[0038] exist Figure 1 First, the baseband processing module frame 2 is pulled out through the baseband processing module guide rail 6, and the baseband processing module 4 is placed on the baseband processing module frame 2. The baseband processing module 4 can be pulled out and pushed in freely, which facilitates the maintenance of the baseband processing module 4.

[0039] Specifically, the baseband processing module frame 2 includes: an aluminum substrate 11 and aluminum substrate pressure strips 13 fixed on opposite sides of the aluminum substrate 11. The baseband processing module 4 is fixed to the aluminum substrate 11. The aluminum substrate pressure strips 13 and the aluminum substrate 11 form a groove. The baseband processing module guide rail 6 passes through the groove and is slidably connected to it.

[0040] like Figure 2 As shown, the pull handle 15 is screwed into the reserved screw hole of the aluminum substrate 11 to facilitate the pull-out maintenance of the baseband processing module 4. The aluminum substrate pressure strip 13 is fixed to the reserved screw hole of the aluminum substrate 11 by bolts. After installation, the aluminum substrate pressure strip 13 and the aluminum substrate 11 form a groove, which allows the baseband processing module guide rail 6 to pass through, so as to achieve the purpose of forming a slide rail.

[0041] After the above installation is completed, as follows: Figure 3 As shown, the baseband processing module frame 2 and the baseband processing module 4 are inserted into the baseband processing module guide rail 6 as a whole. Then, the baseband processing module guide rail 6 is installed onto the side plate 18 by means of hinge 20 and bolts. The side plate 18 is welded to the left side wall of the explosion-proof housing 1. The guide rail pressure block 19 is fixed on the side plate 18 by bolts to limit the baseband processing module guide rail 6 and make it close to the side plate 18, which is conducive to the heat conduction of the baseband processing module 4. During maintenance, the guide rail pressure block 19 is removed first, the baseband processing module guide rail 6 is adjusted to a suitable position by means of hinge 20, and then the baseband processing module 4 is pulled out by means of pull handle 15.

[0042] In mining 5G applications, commercial 5G equipment is usually placed in explosion-proof enclosures to meet explosion-proof requirements. However, because the inside of the explosion-proof enclosure is in a high-temperature state for a long time, the environmental adaptability of commercial equipment is poor. Therefore, the mining 5G equipment often crashes or malfunctions during operation, and in severe cases, it may even cause the entire mine's production to stop.

[0043] Based on the above problems, in this embodiment of the utility model, a heat-spreading pure copper plate 12 is fixedly connected to the CPU of the baseband processing module 4. The heat-spreading pure copper plate 12 is fixed to the CPU of the baseband processing module 4 by the heat-spreading plate pressure column 14 and bolts, thereby expanding the heat dissipation area of ​​the CPU.

[0044] Specifically, a resin anti-collision plate 16 is fixed on the side of the baseband processing module 4 away from the CPU. The resin anti-collision plate 16 is installed on the baseband processing module 4 by a hexagonal fixing copper post 17 to prevent damage or short circuit of the baseband processing module 4 due to physical contact.

[0045] refer to Figure 4 , Figure 4 A schematic diagram of the installation structure of the switch module and transformer provided in this embodiment of the utility model is shown below. Figure 4 As shown, a sliding drawer 3 is provided on the inner wall of the explosion-proof enclosure 1. The switch module 5 and the transformer 24 are fixed on the sliding drawer 3 so that the switch module 5 and the transformer 24 can be pulled out or pushed into the explosion-proof enclosure 1.

[0046] exist Figure 1 First, pull out the baseband processing module rack 2 via the baseband processing module guide rail 6, then pull out the sliding drawer 3. Place the baseband processing module 4 on the baseband processing module rack 2, and place the switch module 5 and transformer 24 on the sliding drawer 3. The baseband processing module 4, switch module 5, and transformer 24 can be freely pulled out and pushed in via the 5G base station rack guide rail 6 and sliding drawer 3, facilitating maintenance of the baseband processing module 4. Connect the backhaul port of the baseband processing module 4 to the optical port of the switch module 5 using the internal optical fiber 10. Then, pull out optical fibers from the fronthaul port of the baseband processing module 4 and the switch module 5, respectively, and connect them to the RF remote unit and the industrial ring network via the fiber optic quick-connect interface 25. Connect the power input ports of the baseband processing module 4 and the switch module 5 to the power output port of the transformer 24 using power cables. Connect the power input port of the transformer 24 to external AC power via the power quick-connect interface 8 using power cables. After installation and wiring, push the baseband processing module rack 2 and sliding drawer 3 in and tighten them with bolts.

[0047] Figure 4 The installation method for switch module 5 and transformer 24 is explained below. Right side plate 21 is welded to the right side wall of explosion-proof housing 1. The sliding drawer mounting bracket 7 and base support bracket 22 are bolted onto the pre-drilled holes in explosion-proof housing 1. Then, switch module 5 and transformer 24 are bolted to the sliding drawer. Finally, the sliding drawer 3 is pushed into the support plate 23 and the fixing bolts are tightened to complete the installation. For maintenance, simply unscrew the bolts securing the sliding drawer 3 and pull out the module for maintenance.

[0049] In this embodiment, reference Figure 5 and Figure 6 , Figure 5This is a first orientational schematic diagram of the heat dissipation fins provided in an embodiment of the present invention. Figure 6 This is a second-positional schematic diagram of the heat dissipation fins provided in an embodiment of the present invention, as shown below. Figure 5 and Figure 6 As shown, the outer wall of the explosion-proof housing 1 is fixed with heat dissipation fins 9, which are located at the position of the baseband processing module 4. The baseband processing module 4 uses industrial-grade electrical components.

[0050] This invention utilizes all industrial-grade electrical components in the PCB design of the baseband processing module 4, eliminating the BMC system and unnecessary devices. Some non-business-related program processes are designed to be actively enabled, thereby reducing the power consumption and heat generation of the baseband processing module 4 and making it more adaptable to the harsh underground environment. For heat dissipation, the core module is mounted against the wall and equipped with heat dissipation fins 9. The heat dissipation fins 9 are welded to the left side wall surface of the explosion-proof housing 1. The baseband processing module 4 is heated evenly through the aluminum substrate 11, and the heat exchange with the air is completed by the heat dissipation fins 9. The fins are long strip metal plates with beveled edges and continuous welding on the side connected to the explosion-proof housing 1. By controlling the welding process of the fins, a seamless connection between the fins and the housing is achieved, thereby avoiding cavities at the contact surface that would affect the overall heat dissipation efficiency, ultimately achieving the goal of working in high-temperature environments.

[0051] Optionally, all fiber optic quick-connect interfaces 25 are clustered interfaces, and a single fiber optic quick-connect interface 25 can lead out the optical ports of 3 baseband processing modules 4 or switch modules 5.

[0052] Typically, one fiber optic cable runs through one interface. This invention integrates three fiber optic cables into a single quick-connect interface, saving housing space. More fiber optic cables can be accommodated within the same interface size. Figure 7 As shown, all 10 fiber optic quick-connect interfaces 25 are clustered interfaces, with each interface having 6 pigtails bundled together. A single fiber optic quick-connect interface 25 can lead out to 3 optical ports of the baseband processing module 4 or the switch module (5). Optionally, the uplink port 26 of the baseband processing module 4 is connected to the 10 Gigabit optical port 33 of the switch module 5 via fiber optic cable 10, the 4 downlink ports 27 of the baseband processing module 4 are connected to 2 fiber optic quick-connect interfaces 25, and the 1 management and maintenance port 28 of the baseband processing module 4 is connected to the 1 Gigabit optical port 34 of the switch module 5.

[0053] Optionally, the three unused 10 Gigabit optical ports 33 of switch module 5 are connected to one fiber optic quick-connect interface 25, and the seven unused Gigabit optical ports 34 of switch module 5 are connected to the three fiber optic quick-connect interfaces 25.

[0054] The internal wiring of this utility model is as follows: the uplink port 26 of the baseband processing module 4 is connected to the 10 Gigabit optical port 33 of the switch module 5 via optical fiber 10; the four downlink ports 27 of the baseband processing module 4 are connected to two optical fiber quick-connect interfaces 25; the one management and maintenance port 28 of the baseband processing module 4 is connected to one gigabit optical port 34 of the switch module 5; the three unused 10 Gigabit optical ports 33 of the switch module 5 are connected to one optical fiber quick-connect interface 25; the seven unused gigabit optical ports 34 of the switch module 5 are connected to three optical fiber quick-connect interfaces 25; and the remaining four optical fiber quick-connect interfaces 25 are reserved. The power quick-connect interface 8 is used for the introduction of external power supply. One power quick-connect interface is connected to the live wire 35 and neutral wire 36 of the transformer 24 through a power cable. The 12V output positive terminal 37 and 12V output negative terminal 38 of the transformer 24 are connected to the 12V input positive terminal 29 and 12V input negative terminal 30 of the baseband processing module 4 through a power cable, respectively. The 12V output positive terminal 39 and 12V output negative terminal 40 of the transformer 24 are connected to the 12V input positive terminal 31 and 12V input negative terminal 32 of the switch module 5 through a power cable, respectively. The reserved port 41 of the baseband processing module 4 is reserved as an uplink interface.

[0055] like Figure 8 As shown, this utility model can connect the core switch on the well top and the 5G base station on the well bottom via the fiber optic quick-connect interface 25. The base station controllers can also be interconnected. An industrial ring network can be formed without the need to deploy a special industrial switch. The control platform on the well can manage and control the baseband processing module system.

[0056] The industrial-grade design of the core mechanism is achieved by combining multiple existing technical solutions. One aspect is the baseband processing module architecture. Most industry-standard architectures use a motherboard + PCIe expansion card, which consumes significant power and generates considerable heat, making it unsuitable for high-temperature, enclosed environments like mines. This invention integrates the original PCIe expansion card functionality onto the motherboard, enabling base station controller functionality with a single motherboard, thus reducing overall power consumption and heat generation. Furthermore, the baseband processing module in this invention uses only industrial-grade wide-temperature-range electronic components in its PCB design, as these components possess excellent high-temperature resistance. The system program has also been optimized to reduce processes unrelated to business logic during startup and operation, further lowering the overall power consumption of the module.

[0057] The above-described embodiments are merely a few specific examples of this utility model. However, the embodiments of this utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
