TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, and more particularly to a dual-mode carrier based on a wide area network and a multi-source positioning unbounded medium. BACKGROUND

[0002] In municipal engineering construction, in order to facilitate the use of urban unmanned driving, power, communication and other pipelines and their accessories, the data communication and device positioning of related intelligent monitoring terminals, gateways, concentrators and monitoring platforms will be transmitted through passive carrier media, but due to the high requirements for carrier site space and installation, it is difficult to control the signal strength and directivity, thereby greatly affecting the terminal data transmission delay and packet loss rate. Further, the platform end failure and offline phenomenon are serious, resulting in misjudgment. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a dual-mode carrier based on a wide area network and a multi-source positioning unbounded medium, which has the advantages of solving the comprehensive problem of misjudgment caused by the difficulty in controlling signal strength and directivity.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a dual-mode carrier based on a wide area network and a multi-source positioning unbounded medium:

[0005] The plastic outer sleeve protects the array and plays a waterproof and dustproof role, and the radio frequency connecting line is connected to the output of the short circuit module RF signal of the communication module; the passive array is used for converting the energy propagation mode. It has the functions of guiding and amplifying electromagnetic waves, so that the electromagnetic signals received by the antenna are stronger, and the high-frequency oscillation current is converted into electromagnetic waves that can propagate in free space. The plastic outer sleeve is internally provided with a positioning array and a wide-area array;

[0006] The wide-area radio frequency connecting output line is used for transmitting the wide-area network signal of the communication module to the wide-area array;

[0007] The positioning radio frequency connecting output line is used for transmitting the wide-area network signal of the communication module to the positioning array.

[0008] The material of the plastic outer sleeve is ABS or PC silicone composite material.

[0009] The plastic outer sleeve has an IP67 or above protection level.

[0010] The wide-area array adopts a multi-band inverted F antenna made of printed circuit board etching or LDS laser direct structuring process, covering 2G / 3G / 4G / 5G Sub-6GHz frequency bands.

[0011] The positioning array has a helical antenna structure.

[0012] The wide-area radio frequency connection output line adopts a low-loss coaxial cable, matching the 4G / 5G frequency band.

[0013] The positioning radio frequency connection output line adopts an anti-interference shielded cable, covering the GNSS frequency band.

[0014] The application has the following beneficial effects:

[0015] By integrating the 4G wide-area network array and the positioning array in a single plastic shell, the spatial redundancy of the separate antennas is eliminated, the product volume is significantly reduced, the dependence on installation space for deployment is reduced, and the application is especially suitable for embedded applications in space-limited scenarios such as urban unmanned driving and power pipeline.

[0016] The dual-mode antenna structure shares the radio frequency connection line with the shell assembly, reducing the material cost of independently purchasing and assembling multiple sets of antennas; at the same time, the installation process is simplified, avoiding the time loss caused by the coordination of multiple components, and the total cost of hardware and construction is reduced.

[0017] The optimized arrangement of the passive array and the electromagnetic wave directional technology improve the energy conversion efficiency of the antenna, enhance the wide-area network signal coverage strength and the positioning signal reception sensitivity, reduce the data transmission delay and packet loss rate, and effectively reduce the misjudgment and offline failure of the remote platform end.

[0018] The plastic shell adopts a waterproof and dustproof packaging process to ensure the long-term stability of the antenna in complex municipal engineering environments (such as underground pipeline networks and humid power facilities), avoid signal attenuation or device failure caused by environmental erosion, and prolong the life cycle of the equipment.

[0019] The antenna design integrates multiple source positioning technologies (such as GPS / Beidou / Wi-Fi assisted positioning), optimizes the spatial signal analysis capability through array cooperation, improves the positioning accuracy in complex urban environments, and meets the high-precision demand scenarios such as unmanned driving and asset tracking.

[0020] The standardized radio frequency interface design supports plug-and-play of mainstream communication modules, can adapt to various wide-area network protocols such as 4G / 5G, LoRa, and NB-IoT, is convenient for subsequent technology iteration and function expansion, reduces the difficulty and cost of upgrading and reconstruction.

[0026] For the sake of understanding, the specific flow of the embodiments of the present application is described below. Please refer to Figure 1 and Figure 2 The first embodiment of the dual-mode carrier based on the wide-area network and the multi-source positioning unbounded medium in the embodiments of the present application includes:

[0027] The scheme is a highly integrated dual-mode communication and positioning carrier. The antenna functions of the wide-area network (such as 4G / 5G) and the positioning system (such as GPS / Beidou / multi-source fusion positioning) are integrated through an integrated physical structure design. The specific structural composition is as follows:

[0028] Plastic outer sleeve (1)

[0029] Material and protection characteristics: engineering-grade modified plastic materials (such as ABS or PC+silicone composite) are used, with IP67 and above protection level, sealed design can prevent dust and water (including rainwater immersion or high-pressure washing), suitable for municipal underground pipe network, power equipment and other humid, dusty environments.

[0030] Structural design: the outer sleeve provides physical support for the internal antenna array. The array and the radio frequency line are integrated and packaged by in-mold injection or buckle fixation to avoid structural loosening caused by mechanical vibration. The surface of the shell can be additionally provided with heat dissipation grooves or flow guide textures to adapt to high temperature or open air environments.

[0031] Wide-area radio frequency connection output line (2) and positioning radio frequency connection output line (3)

[0032] Function implementation:

[0033] Wide Area Network Connection Line: Low-loss coaxial cable (such as RG316) is used to match the 4G / 5G frequency band (such as 700MHz-3.5GHz), responsible for transmitting the wide area network signals (such as LTE, NB-IoT) of the communication module to the wide area array (5).

[0034] Positioning Connection Line: Anti-interference shielded cable is selected to cover the GNSS frequency band (such as GPS L1 / L5, Beidou B1 / B3), transmitting satellite signals output by the positioning module to the positioning array (4).

[0035] Interface Standardization: The output line end is equipped with industry-standard RF connectors such as SMA / IPEX, supporting plug-and-play and compatibility with mainstream communication modules (such as Quectel, Yiyuan modules).

[0036] Positioning Array (4) and Wide Area Array (5)

[0037] Passive Array Core Design:

[0038] Wide Area Array: Multi-band inverted-F antenna (PIFA) made of printed circuit board (PCB) etching or LDS laser direct structuring process, covering 2G / 3G / 4G / 5G Sub-6GHz frequency band, optimizing space utilization through serpentine wiring, gain up to 3-5dBi.

[0039] Positioning Array: Patch antenna or spiral antenna structure based on ceramic medium loading, enhancing the receiving sensitivity of GNSS signals (1.1-1.6GHz), supporting multi-star and multi-frequency positioning, directional beam width ≥120° to achieve wide area coverage.

[0040] Electromagnetic Compatibility Design: Two arrays are separated by physical isolation (spacing ≥λ / 4, λ is the highest frequency wavelength) and ground plane separation technology to avoid intermodulation interference between wide area and positioning frequency bands, ensuring signal purity.

[0041] Technical Principle:

[0042] The communication module sends modulated high-frequency current signals to the wide area array (5) through the wide area radio frequency line (2), and the array converts them into electromagnetic wave radiation to free space; the reverse is completed when receiving electromagnetic wave-current conversion, realizing uplink and downlink data transmission with the base station.

[0043] The positioning array (4) receives satellite / base station hybrid positioning signals, transmits them to the positioning module through the radio frequency line (3) to calculate the position information, and supports TOA (time of arrival) / TDOA (time difference of arrival) algorithm, improving the positioning accuracy (meter level to sub-meter level) in complex urban environments.

[0044] Through the double-array co-housing design, the overall size is reduced by more than 50% compared with the separated antenna (typical size 80mm*30mm*10mm), which can be directly embedded in the device cavity or externally mounted in narrow space (such as manhole cover, street lamp pole).

[0045] The frequency domain isolation and grounding shielding technology is adopted between the arrays to ensure that the positioning signal reception is not affected when the wide area network transmits high power (such as 23dBm), and the bit error rate (BER) is reduced to below 10^-6.

[0046] By using standardized interface and modular design, users can select LoRa, Wi-Fi sub-array or upgrade to 5G millimeter wave array according to needs without changing the main structure.

[0047] The technical parameters are as follows:

[0048] Index Wide-area array (5) Positioning array (4) Operating frequency band 700MHz-3.5GHz GPS L1 / L5, Beidou B1 / B3 Gain 3-5dBi 2-4dBi VSWR <2.0 <1.5 Polarization mode Linear polarization Right-hand circular polarization (RHCP) Environmental adaptability -40℃~+85℃, IP67 -40℃~+85℃, IP67

[0049] The present application integrates the 4G wide area network array and the positioning array in a single plastic shell, eliminates the space redundancy of the separated antenna, significantly reduces the product volume, reduces the dependence of deployment on installation space, and is especially suitable for embedded applications in space-limited scenarios such as urban unmanned driving and power pipeline. The dual-mode antenna structure shares the RF connection line and the shell assembly, reducing the material cost of independent purchase and assembly of multiple sets of antennas; at the same time, it simplifies the installation process, avoids the time loss caused by the coordination of multiple components, and reduces the total cost of hardware and construction. The optimized arrangement of passive arrays and electromagnetic wave directional technology improves the energy conversion efficiency of the antenna, enhances the wide area network signal coverage strength and positioning signal reception sensitivity, reduces the data transmission delay and packet loss rate, effectively reduces the misjudgment and offline failure of the remote platform. The plastic shell adopts waterproof and dustproof packaging process to ensure the long-term stability of the antenna in complex municipal engineering environment (such as underground pipeline network and humid power facilities), avoid signal attenuation or device failure caused by environmental erosion, and prolong the service life of the equipment. The antenna design integrating multiple source positioning technologies (such as GPS / Beidou / Wi-Fi assisted positioning) optimizes the spatial signal analysis capability through array cooperation, improves the positioning accuracy in complex urban environment, and meets the high-precision demand scenarios such as unmanned driving and asset tracking. The standardized RF interface design supports plug-and-play of mainstream communication modules, which can adapt to 4G / 5G, LoRa, NB-IoT and other wide area network protocols, facilitating subsequent technology iteration and function expansion, reducing the difficulty and cost of upgrading and reconstruction.
