Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment, in particular to an emergency communication vehicle antenna and an emergency communication vehicle. Background Art

[0002] As society continues to evolve, major events and emergencies occur frequently. To ensure on-site communication capabilities, an emergency communication system is needed. Specifically, an emergency communication vehicle equipped with antenna equipment is required. This system is used to address unusual situations such as large gatherings of people for major events (such as large-scale sports events and outdoor parties) or when emergencies cause communication disruptions in a specific area (such as damage to a mobile antenna tower in a certain area).

[0003] In the related art, the emergency communication vehicle antenna has the following disadvantages:

[0004] (1) Multiple antennas: Emergency communication vehicles need to meet the requirements of both 4G (4th generation mobile communication technology) and 5G (5th generation mobile communication technology) communications. Accordingly, they need to be equipped with both 4G and 5G antennas. However, the space for mounting antennas on emergency communication vehicles is small, making installation difficult.

[0005] (2) Heavy antenna: The antenna of the emergency communication vehicle needs to be raised and lowered frequently. Since it carries both 4G and 5G antennas, the fixed load-bearing burden is too heavy, which can easily cause safety hazards;

[0006] (3) Too many feeders: The existing emergency communication vehicle requires four feeders for the 4G antenna. When the feeders for the 5G antenna are added, the number of feeders increases. The existing winch is unable to meet the requirements for retracting all the feeders.

[0007] (4) A single antenna does not meet the coverage range and network standard capabilities: A single antenna cannot meet the coverage requirements of both 4G and 5G networks at the same time and can only carry a 4G antenna and a 5G antenna at the same time. Utility Model Content

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0047] It should be noted that in the description of this utility model, the orientations or positional relationships indicated by various directional terms are based on the orientations or positional relationships shown in the accompanying drawings. They are intended only to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be understood as limitations on this utility model. Furthermore, the embodiments of this utility model and the features therein may be combined with each other unless they conflict with each other.

[0048] In the description of the present invention, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or system. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or system comprising the element.

[0049] To address the technical issues of existing emergency communication vehicle antennas, such as multiple antennas, heavy weight, multiple feeders, and a single antenna failing to meet coverage requirements and network standards, the present invention provides a multi-frequency emergency communication vehicle antenna based on port integration technology. This antenna achieves the convergence of 4G and 5G networks, enabling a single antenna to simultaneously meet 4G and 5G network coverage requirements, eliminating the need for separate 4G and 5G antennas. This single multi-frequency, multi-mode antenna replaces multiple antennas, while also being lightweight and requiring fewer feeders. This is described in detail below through specific embodiments.

[0050] Example 1:

[0051] like Figures 2 to 7 As shown, this embodiment provides an emergency communication vehicle antenna, including: a reflector 3, and an intermediate frequency radiation unit, a high frequency radiation unit, a plurality of intermediate frequency power splitter boards, a plurality of high frequency power splitter boards, two cable collectors 6 and two cluster connectors 8 arranged on the reflector 3.

[0052] The intermediate frequency (IF) radiating element includes multiple IF dual-polarized oscillators 42, while the high frequency (HF) radiating element includes multiple high-frequency dual-polarized oscillators 41. IF refers to the 1710-2690 MHz frequency band, while HF refers to the 3300-3700 MHz frequency band. The oscillator is a core component of the antenna, guiding and amplifying electromagnetic waves, enhancing the electromagnetic signal received by the antenna.

[0053] like Figure 6 As shown, the intermediate frequency dual-polarization antenna 42 utilizes an integrated PCB antenna, equipped with upper and lower jumpers, feeders, and a supporting substrate. A PCB antenna is a device in which circuits are printed on a PCB board to achieve electromagnetic field propagation. Its lightweight design reduces antenna weight while meeting the requirements for stable antenna performance. The integrated PCB antenna utilizes a double-layer structure with a low dielectric constant and low dielectric loss factor, and employs folded antenna synthesis technology to significantly improve its radiation efficiency. Furthermore, with advancements in high-frequency circuit board processing technology, the integrated PCB antenna offers advantages such as lightweight, design flexibility, and excellent electrical performance, meeting the needs of a wider range of communication antenna applications and contributing to the development of communication technology.

[0054] like Figure 7 As shown, the high-frequency dual-polarization vibrator 41 adopts a metal die-cast vibrator. Since the size of the high-frequency dual-polarization vibrator is relatively small, the quality of the high-frequency dual-polarization vibrator is similar whether it adopts an integrated PCB vibrator or a metal die-cast vibrator, but the metal die-cast vibrator has stable performance and good reliability.

[0055] The intermediate frequency power splitter board and the high frequency power splitter board can be made of high frequency radio frequency circuit board to reduce the internal feed network loss of the antenna.

[0056] Each bundle connector 8 is connected to a bundle cable. Bundled cables are multiple radio frequency cables enclosed in a protective casing, effectively reducing the number of cables and the complexity of wiring.

[0057] Specifically, the positive polarization signals and negative polarization signals of the multiple intermediate frequency dual-polarization transducers 42 are combined into one positive polarization signal and one negative polarization signal, respectively, by multiple intermediate frequency power splitters. The positive polarization signals and negative polarization signals of the multiple high frequency dual-polarization transducers 41 are combined into N positive polarization signals and N negative polarization signals, respectively, by multiple high frequency power splitters. The one positive polarization signal corresponding to the multiple intermediate frequency dual-polarization transducers 42 and the N positive polarization signals corresponding to the multiple high frequency dual-polarization transducers 41 are combined into N+1 multi-frequency positive polarization signals through a cable aggregator 6 and then input or output through a cluster connector 8. The one negative polarization signal corresponding to the multiple intermediate frequency dual-polarization transducers 42 and the N negative polarization signals corresponding to the multiple high frequency dual-polarization transducers 41 are combined into N+1 multi-frequency negative polarization signals through another cable aggregator 6 and then input or output through another cluster connector 8. N is a positive integer, for example, N can be 1, 2, 3, or 4.

[0058] Among them, the high-frequency signal cables and medium-frequency signal cables of the same polarity are assembled through a cable hub. A cable hub refers to a carrier composed of multiple cables or optical cables. The cables or optical cables can be of the same type or different types. It is mainly for the convenience of wiring and maintenance. In addition to using cable hubs, you can also use cable ties (zip ties), cable clamps, cable fixers, cable sleeves, junction boxes, etc. to organize multiple cables or optical cables into a cable hub for easy management and use. Depending on the type of cable or optical cable, cable hubs can be divided into the following categories: Same type cable hub: refers to a hub composed of cables or optical cables of the same type, such as power cables, communication cables, control cables, optical fiber cables, etc. of the same type; Different type cable hub: refers to a hub composed of cables or optical cables of different types, such as a combination of power cables, communication cables and control cables; Mixed cable hub: refers to a hub composed of cables or optical cables of different manufacturers, models, specifications, etc.

[0059] In this embodiment, the emergency communication vehicle antenna has both a medium-frequency radiation unit and a high-frequency radiation unit, which can meet the 4G and 5G network coverage requirements at the same time. Compared with the existing emergency communication vehicle antenna that is equipped with a 4G antenna and a 5G antenna respectively, it not only reduces the number of antennas, but also reduces the weight of the antenna. Moreover, the medium-frequency radiation unit and the high-frequency radiation unit merge the signals through the medium-frequency power splitter board and the high-frequency power splitter board respectively, and then the cables are aggregated through the cable collector, and then connected to the two bundled cables through two bundled connectors, which greatly reduces the number of antenna feed lines, facilitates the winch to retract and extend the feed lines, solves the problem of difficulty in winding the antenna feed lines, and further reduces the weight of the antenna.

[0060] In a specific embodiment, Figure 2 and Figure 3 As shown, the intermediate frequency radiation unit and the high frequency radiation unit are located on the front of the reflection plate 3 ; multiple intermediate frequency power splitter boards, multiple high frequency power splitter boards and two cable collectors 6 are located on the back of the reflection plate 3 .

By arranging the intermediate frequency radiating unit and the high frequency radiating unit on the front of the reflector 3 and the intermediate frequency power splitter board, the high frequency power splitter board, and the cable manifold on the back of the reflector 3, the space on the reflector 3 is rationally utilized, making the entire antenna structure more compact, correspondingly reducing the overall size of the antenna, and simplifying and convenient installation.

[0071] Among them, the antenna cover 2 is a hollow structure with openings at both ends, and a placement chamber is provided therein. The reflector 3 is located in the placement chamber. Correspondingly, the intermediate frequency radiation unit, high frequency radiation unit, intermediate frequency power splitter board, high frequency power splitter board, cable collector 6, etc. are also located in the placement chamber; the upper end cover 9 and the lower end cover 10 are respectively arranged at both ends of the antenna cover 2.

[0072] like Figure 1 As shown, the radome 2 is a rectangular parallelepiped structure with a slightly curved surface. Its front side is a slightly curved surface, and its side and back sides are flat. The front side of the reflector 3 faces the front side of the radome 2, and the back side of the reflector 3 faces the back side of the radome 2.

[0073] The antenna cover 2, the upper end cover 9 and the lower end cover 10 can all be made of fiberglass or UPVC. These two materials have the advantages of high strength and light weight, are easy to install and use, and can prevent rust.

Figure 8 As shown, two through holes are provided on the lower end cover 10 at positions corresponding to the two cluster joints 8, and the two cluster joints 8 are detachably connected to the joint surface of the reflector 3 through the two through holes on the lower end cover 10; the lower end cover 10 can also be connected to the joint surface of the reflector 3 by bolts, so that the joint surface of the reflector 3 is installed on the lower end cover 10.

[0075] In this embodiment, in addition to the two through holes for the two cluster joints 8 to pass through, the lower end cover 10 can also be provided with multiple bolt through holes, and the joint surface connection between the lower end cover 10 and the reflector 3 is achieved by stainless steel bolts passing through the bolt through holes on the lower end cover 10.

[0077] For example, four support members 7 are used, with two in each group, where one group of support members 7 is arranged on the reflector 3 near the upper end cover 9 , and another group of support members 7 is arranged on the reflector 3 near the lower end cover 10 .

[0078] In this embodiment, multiple supports 7 are provided between the reflector 3 and the back of the radome 2 to secure the reflector 3 to the radome 2. By assembling the intermediate frequency dual-polarization oscillator 42, the high frequency dual-polarization oscillator 41, the intermediate frequency power splitter board, the high frequency power splitter board, the cable collector 6, the supports 7, and the cluster connector 8 on a single reflector, the overall size of the antenna is effectively reduced.

[0081] In this embodiment, the mounting plate 1 adopts a structure with a convex middle and flat sides, and can be made of metal, such as stainless steel. By arranging the mounting plate 1 on the outer surface of the back of the antenna cover 2, it is convenient to fix the antenna on the emergency communication vehicle.

The five negative polarization signals combined by the ten high-frequency dual-polarization transducers 41 in the five small groups are combined into one negative polarization signal via the high-frequency one-to-five power splitter 52.

[0102] This embodiment also provides an emergency communication vehicle, comprising: a vehicle body and the above-mentioned emergency communication vehicle antenna.

[0103] The emergency communication vehicle antenna and the emergency communication vehicle provided by the embodiment of the present invention have the following characteristics:

[0104] (1) Light weight: First, the intermediate frequency dual-polarization vibrator adopts an integrated PCB vibrator. Compared with the die-cast vibrator, the PCB vibrator is nearly half as heavy as the die-cast vibrator, which can solve the problem of the heavy antenna of the emergency communication vehicle. The PCB vibrator improves the stability and integration of the PCB vibrator performance through integrated design and precise manufacturing process; secondly, the power splitter board and cable collector design are adopted. The power splitter board adopts high-frequency plate and cable power splitter design, and the cable collector adopts high-frequency plate design, which can greatly reduce the weight of the power splitter board and cable collector, meeting the antenna design requirements.

[0105] (2) Reduce the number and weight of cables: By optimizing the phase of the radiating unit, the number of cables is reduced. By using built-in combining technology and port integration technology, the original 10 feeder lines are combined into 2 bundled cables, solving the winch problem and meeting the weight reduction requirements.

[0106] (3) Improve antenna gain and efficiency: Using low-loss green antennas can reduce losses, and optimizing the power and phase of each port of the feed network through simulation can improve antenna gain. Low-loss and high-efficiency green antennas can be combined with cellular ultra-low-loss cables, self-developed air cavity connectors that are connected to the cable collector as adapters, and power splitters made of high-frequency RF circuit boards to minimize the loss of the antenna's internal feed network. The cellular ultra-low-loss cable has a 20% lower loss per meter than the traditional 141 cable, and the self-developed air cavity connector has a 50% lower loss than the traditional cable collector adapter. Low-insertion-loss modular integration solutions can also be used to integrate low-insertion-loss phase shifters and feed networks, high-radiation-efficiency radiating units, and low-insertion-loss feeders, minimizing antenna internal losses and improving antenna gain and efficiency. Under the same input power, the base station has a larger coverage range, which is conducive to reducing base station density; under the same coverage range, the base station has a lower input power, which is conducive to reducing base station energy consumption.

[0107] (4) Technical scalability: The emergency communication vehicle adopts a 2+8-port medium and high frequency antenna to achieve a lightweight and low-feeder design. The combined circuit and port integration adopted can continue the antenna design requirements of other emergency communication vehicles and meet the requirements of 4G / 5G network activation.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
