DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for the sake of ease of description, only the parts related to the present application are shown in the accompanying drawings, rather than all the contents.

[0023] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] Figure 1 A schematic diagram of the structure of an all-in-one antenna module provided in an embodiment of the present application is given, referring to Figure 1 The all-in-one antenna module includes a main combiner 100 , a secondary combiner 200 , a main antenna module 300 and a secondary antenna module 400 .

[0025] The main combiner 100 and the secondary combiner 200 provided in this solution are used to simultaneously connect multiple communication modules 500 on unmanned equipment. Optionally, different communication modules 500 may correspond to different wireless communication functions. For example, the communication module 500 may be a combination of one or more of a cellular network communication module (such as a 4G, 5G communication module, etc.), an RTK (Real-time kinematic) communication module 500, and a WiFi communication module. The multiple communication modules 500 provided in this solution include at least a cellular network communication module and an RTK communication module.

[0026] Among them, each communication module 500 can be connected to the main antenna and the auxiliary antenna at the same time (this solution connects the main antenna module 300 and the auxiliary antenna module 400 to the corresponding communication module 500 through the main combiner 100 and the auxiliary combiner 200). Different types of communication modules 500 can be configured with different communication channels according to the communication characteristics of the main antenna and the auxiliary antenna to which they are connected. For example, the communication channel connected to the main antenna of the cellular network communication module is a transceiver channel (i.e., a channel that can receive and send data), and the communication channel connected to the auxiliary antenna is a receiving channel (i.e., a channel that only receives data), the communication channel connected to the main antenna of the RTK communication module and the communication channel connected to the auxiliary antenna are both receiving channels, and the communication channel connected to the main antenna of the WiFi communication module and the communication channel connected to the auxiliary antenna are both transceiver channels.

[0027] The main antenna module 300 provided in this solution includes a plurality of main antenna submodules 310 corresponding to a communication module 500 respectively and a first multiplexing module 320, wherein the plurality of main antenna submodules 310 are connected to the first multiplexing module 320, and the first multiplexing module 320 is connected to the main combiner 100 via a signal transmission line (e.g., a radio frequency coaxial line). For example, the main antenna module 300 may be a combination of one or more of a cellular network main antenna 311 submodule 310, an RTK main antenna submodule 310, and a WiFi main antenna submodule 310. The sub-antenna module 400 provided in this solution includes a plurality of sub-antenna submodules 410 corresponding to a communication module 500 respectively and a second multiplexing module 420, wherein the plurality of sub-antenna submodules 410 are connected to the second multiplexing module 420, and the second multiplexing module 420 is connected to the sub-combiner 200 via a signal transmission line (e.g., a radio frequency coaxial line). For example, the sub-antenna module 400 may be a combination of one or more of a cellular network sub-antenna submodule, an RTK sub-antenna submodule, and a WiFi sub-antenna submodule. The first multiplexing module 320 provided in this solution can be used to separate the uplink data provided by the main combiner 100, or to merge the downlink data provided by each main antenna submodule 310. The second multiplexing module 420 can be used to separate the uplink data provided by the secondary combiner 200, or to merge the downlink data provided by each secondary antenna submodule 410.

[0028] The main combiner 100 and the auxiliary combiner 200 provided in this solution can be used to realize multi-channel frequency combination of different communication modules 500, for example, to realize three-channel frequency combination of cellular network communication module, RTK communication module and WiFi communication module. For example, the main combiner 100 and the auxiliary combiner 200 can be used to send downlink data to the corresponding communication module 500 according to the frequency range corresponding to the received downlink data, and send the uplink data sent by each communication module 500 to the main antenna module 300 and the auxiliary antenna module 400. Different communication modules 500 correspond to different frequency ranges, and the main combiner 100 and the auxiliary combiner 200 can work according to the set working logic. For example, the main combiner 100 is mainly used for data transmission, and when the main combiner 100 is abnormal, it can be switched to the auxiliary combiner 200 for data transmission. The first multiplexing module 320 provided in this solution can be used to send uplink data to the corresponding main antenna submodule 310 according to the frequency range corresponding to the received uplink data, and send the downlink data received by each main antenna submodule 310 to the main combiner 100. The second multiplexing module 420 provided in this solution can be used to send uplink data to the corresponding sub-antenna submodule 410 according to the frequency range corresponding to the received uplink data, and send the downlink data received by each sub-antenna submodule 410 to the sub-combiner 200. The frequency range corresponding to the main antenna submodule 310 and the antenna submodule can be determined based on the frequency range corresponding to the corresponding communication module 500.

[0029] As described above, by using a signal transmission line to connect multiple main antenna submodules 310 corresponding to different communication modules 500 to the main combiner 100 through the first multiplexing module 320, and by using a signal transmission line to connect multiple sub-antenna submodules 410 corresponding to different communication modules 500 to the sub-combiner 200 through the second multiplexing module 420, the main combiner 100 and the sub-combiner 200 can be connected to multiple communication modules 500 at the same time, and the multiple main antenna submodules 310 and sub-antenna submodules 410 corresponding to different communication modules 500 are respectively and centrally connected to the main combiner 100 and the sub-antenna submodule 410, and there is no need for each main antenna submodule 310 and sub-antenna submodule 410 to be separately connected to the communication module 500, thereby effectively reducing the space occupied by multiple antennas in the device and reducing the consumption of wires.

[0030] In a possible embodiment, the main combiner 100 provided by the present solution includes a third multiplexing module 110, a plurality of communication modules 500 are respectively connected to the multi-end side of the third multiplexing module 110, and the single-end side of the third multiplexing module 110 is connected to the single-end side of the first multiplexing module 320. The third multiplexing module 110 can be used to separate the downlink data provided by the first multiplexing module 320, or to combine the uplink data provided by each of the communication modules 500. For example, the third multiplexing module 110 can send the downlink data to the corresponding communication module 500 according to the frequency range corresponding to the received downlink data, and send the uplink data sent by each communication module 500 to the main antenna module 300.

[0031] In one embodiment, the first multiplexing module 320 is configured with a single-end side and a multi-end side, wherein the single-end side is configured with a single connection port, and the multi-end side is configured with multiple connection ports, and each main antenna submodule 310 is respectively connected to a communication interface of the multi-end side of the first multiplexing module 320. At the same time, the main combiner 100 is configured with a single-end side and a multi-end side, wherein the single-end side is configured with a single connection port, and the multi-end side is configured with multiple connection ports, and each connection port of the main combiner 100 can be respectively connected to a communication module 500. The connection port of the single-end side of the first multiplexing module 320 is connected to the connection port of the single-end side of the main combiner 100, and optionally, the connection port of the single-end side of the first multiplexing module 320 and the connection port of the single-end side of the main combiner 100 can be connected through a radio frequency coaxial line. For example, a radio frequency connector can be set at the connection port of the single-end side of the first multiplexing module 320, and a radio frequency connector can be set at the connection port of the single-end side of the main combiner 100, and the two radio frequency connectors are connected through a radio frequency coaxial line. This solution connects multiple communication modules 500 and the first multiplexing module 320 through the third multiplexing module 110 to achieve connection and data transmission between each main antenna sub-module 310 and the corresponding communication module 500. Each communication module 500 does not need to be separately connected to the main antenna sub-module 310. While ensuring normal data communication, it effectively reduces the consumption of antenna connection cables and reduces the space occupied by wires in the equipment.

[0032] like Figure 2 As shown in the structural diagram of a main combiner provided, the third multiplexing module 110 provided in this solution includes a plurality of first duplexers 111, and each connection port on the multi-end side of the plurality of first duplexers 111 is respectively connected to a single-end side of a communication module 500 or other first duplexers 111, wherein the single-end side of one first duplexer 111 is connected to the single-end side of the first multiplexing module 320. The first duplexer 111 provided in this solution can be used to separate the downlink data provided by the connected first multiplexing module 320 or other first duplexers 111, or to merge the uplink data provided by the connected communication module 500 and / or other first duplexers 111.

[0033] Exemplarily, the number of first duplexers 111 provided in this solution can be configured according to the number of communication modules 500. For example, when the number of communication modules 500 is n, the number of corresponding first duplexers 111 can be set to n-1. A plurality of first duplexers 111 can form a tree network structure, wherein one first duplexer 111 serves as the root node of the tree network structure, and its single-end side is connected to the single-end side of the first multiplexing module 320 through a radio frequency coaxial line, and the remaining first duplexers 111 serve as leaf nodes of the tree network structure, and the multi-end side of each first duplexer 111 can be connected to a communication module 500 or the single-end side of other first duplexers 111. This solution realizes the combined connection of multiple communication modules 500 through multiple first duplexers 111, and uniformly connects multiple communication modules 500 to the first multiplexing module 320. Each communication module 500 does not need to be separately connected to the main antenna submodule 310. While ensuring normal data communication, it effectively reduces the consumption of antenna connection cables and reduces the space occupied by wires in the device.

[0034] Optionally, when the communication module 500 (for example, an RTK communication module) needs to filter the first frequency range signal (low frequency range signal) and the second frequency range signal (high frequency range signal) within the communication frequency range to improve anti-interference capability, a first frequency division filter module can be connected between the communication module 500 and the corresponding first duplexer 111, and the first frequency division filter module performs frequency division filtering on the transmission data between the communication module 500 and the corresponding first duplexer 111. Optionally, the first frequency division filtering module may include a ninth duplexer 811, a tenth duplexer 812, a first filter 813 and a second filter 814, wherein the single-end side of the ninth duplexer 811 is connected to the corresponding communication module 500, a connection port on the double-end side of the ninth duplexer 811 is connected to a connection port on the double-end side of the tenth duplexer 812 via the first filter 813, another connection port on the double-end side of the ninth duplexer 811 is connected to another connection port on the double-end side of the tenth duplexer 812 via the second filter 814, and the single-end side of the tenth duplexer 812 is connected to a connection port on the multi-end side of the corresponding first duplexer 111. Among them, the ninth duplexer 811 can be used to separate the uplink data provided by the connected communication module 500, or to merge the downlink data provided by the first filter 813 and the second filter 814. For example, the ninth duplexer 811 distributes the uplink data to the first filter 813 or the second filter 814 according to the frequency range corresponding to the uplink data sent by the communication module 500. The first filter 813 or the second filter 814 filters out the information of the uplink data outside the corresponding frequency range, and sends the filtered uplink data to the tenth duplexer 812, and the duplexer sends the uplink data to the first duplexer 111. The tenth duplexer 812 can be used to separate the downlink data provided by the connected first duplexer 111, or to merge the uplink data provided by the first filter 813 and the second filter 814. For example, the tenth duplexer 812 distributes the downlink data to the first filter 813 or the second filter 814 according to the frequency range corresponding to the received downlink data, and the first filter 813 or the second filter 814 filters out the information of the downlink data outside the corresponding frequency range, and sends the filtered downlink data to the ninth duplexer 811, and the ninth duplexer 811 sends the downlink data to the communication module 500. Optionally, the ninth duplexer 811 and the tenth duplexer 812 can be GNSS LTCC duplexers, the first filter 813 and the second filter 814 can be surface acoustic wave filters (SAW), and the first frequency division filtering module can be a GNSS high and low frequency duplexer.

The fourth multiplexing module 210 can be used to send downlink data to the corresponding communication module 500 according to the frequency range corresponding to the received downlink data, and send the uplink data sent by each communication module 500 to the secondary antenna module 400. The fourth multiplexing module 210 provided by the present solution can be used to separate the downlink data provided by the second multiplexing module 420, or to combine the uplink data provided by each of the communication modules 500.

[0036] In one embodiment, the second multiplexing module 420 is configured with a single-end side and a multi-end side, wherein the single-end side is configured with a single connection port, and the multi-end side is configured with multiple connection ports, and each secondary antenna submodule 410 is respectively connected to a communication interface of the multi-end side of the second multiplexing module 420. At the same time, the secondary combiner 200 is configured with a single-end side and a multi-end side, wherein the single-end side is configured with a single connection port, and the multi-end side is configured with multiple connection ports, and each connection port of the secondary combiner 200 can be respectively connected to a communication module 500. The connection port of the single-end side of the second multiplexing module 420 is connected to the connection port of the single-end side of the secondary combiner 200, and optionally, the connection port of the single-end side of the second multiplexing module 420 and the connection port of the single-end side of the secondary combiner 200 can be connected through a radio frequency coaxial line. For example, a radio frequency connector can be set at the connection port of the single-end side of the second multiplexing module 420, and a radio frequency connector can be set at the connection port of the single-end side of the secondary combiner 200, and the two radio frequency connectors are connected through a radio frequency coaxial line. This solution connects multiple communication modules 500 and the second multiplexing module 420 through the fourth multiplexing module 210 to achieve connection and data transmission between each auxiliary antenna sub-module 410 and the corresponding communication module 500. Each communication module 500 does not need to be separately connected to the auxiliary antenna sub-module 410. While ensuring normal data communication, it effectively reduces the consumption of antenna connection cables and reduces the space occupied by wires in the equipment.

[0037] like Figure 3As shown in the structural diagram of a sub-combiner provided, the fourth multiplexing module 210 provided in this solution includes a plurality of second duplexers 211, and each connection port on the multi-end side of the plurality of second duplexers 211 is respectively connected to a single-end side of a communication module 500 or other second duplexers 211, wherein the single-end side of one second duplexer 211 is connected to the single-end side of the second multiplexing module 420. Among them, the sub-combiner 200 provided in this solution is consistent with the configuration of the main combiner 100, and the sub-combiner 200 can be set with reference to the configuration of the main combiner 100. The second duplexer 211 provided in this solution can be used to separate the downlink data provided by the connected second multiplexing module 420 or other second duplexers 211, or to merge the uplink data provided by the connected communication module 500 and / or other second duplexers 211.

[0038] Exemplarily, the number of second duplexers 211 provided in this solution can be configured according to the number of communication modules 500. For example, when the number of communication modules 500 is n, the number of corresponding second duplexers 211 can be set to n-1. A plurality of second duplexers 211 can form a tree network structure, wherein one second duplexer 211 serves as the root node of the tree network structure, and its single-end side is connected to the single-end side of the second multiplexing module 420 through a radio frequency coaxial line, and the remaining second duplexers 211 serve as leaf nodes of the tree network structure, and the multi-end side of each second duplexer 211 can be connected to a communication module 500 or the single-end side of other second duplexers 211. This solution realizes the combined connection of multiple communication modules 500 through multiple second duplexers 211, and uniformly connects multiple communication modules 500 to the second multiplexing module 420. Each communication module 500 does not need to be connected to the secondary antenna submodule 410 separately, and while ensuring normal data communication, it effectively reduces the consumption of antenna connection cables and reduces the space occupied by wires in the device.

[0039] Optionally, when the communication module 500 (for example, an RTK communication module) needs to filter the first frequency range signal (low frequency range signal) and the second frequency range signal (high frequency range signal) within the communication frequency range to improve anti-interference capability, a second frequency division filter module may be connected between the communication module 500 and the corresponding second duplexer 211, and the second frequency division filter module performs frequency division filtering on the transmission data between the communication module 500 and the corresponding second duplexer 211. Optionally, the second frequency division filtering module may include an eleventh duplexer 815, a twelfth duplexer 816, a third filter 817 and a fourth filter 818, wherein the single-end side of the eleventh duplexer 815 is connected to the corresponding communication module 500, a connection port on the double-end side of the eleventh duplexer 815 is connected to a connection port on the double-end side of the twelfth duplexer 816 via the third filter 817, another connection port on the double-end side of the eleventh duplexer 815 is connected to another connection port on the double-end side of the twelfth duplexer 816 via the fourth filter 818, and the single-end side of the twelfth duplexer 816 is connected to a connection port on the multi-end side of the corresponding second duplexer 211. Among them, the eleventh duplexer 815 can be used to separate the uplink data provided by the connected communication module 500, or to merge the downlink data provided by the third filter 817 and the fourth filter 818. For example, the eleventh duplexer 815 distributes the uplink data to the third filter 817 or the fourth filter 818 according to the frequency range corresponding to the uplink data sent by the communication module 500. The third filter 817 or the fourth filter 818 filters out the information of the uplink data outside the corresponding frequency range, and sends the filtered uplink data to the twelfth duplexer 816, and the duplexer sends the uplink data to the second duplexer 211. The twelfth duplexer 816 can be used to separate the downlink data provided by the connected second duplexer 211, or to merge the uplink data provided by the third filter 817 and the fourth filter 818. For example, the twelfth duplexer 816 distributes the downlink data to the third filter 817 or the fourth filter 818 according to the frequency range corresponding to the received downlink data, and the third filter 817 or the fourth filter 818 filters out the information of the downlink data outside the corresponding frequency range, and sends the filtered downlink data to the eleventh duplexer 815, and the eleventh duplexer 815 sends the downlink data to the communication module 500.

Assume that the frequency range corresponding to the cellular network communication module (taking the 4G communication module as an example) is: low frequency 698MHz~960MHz, high frequency 1710MHz~2170MHz; the frequency range corresponding to the RTK communication module is: low frequency (L2+L5) 1164MHz~1286MHz, high frequency (L1) 1559MHz~1591MHz; the frequency range corresponding to the WiFi communication module is: low frequency 2400MHz~2500MHz, high frequency 5150MHz~5850MHz. The frequency range corresponding to the RTK communication module is determined based on the L1, L2 and L5 frequency bands based on the GPS system, and can also be set according to the frequency bands corresponding to satellite systems such as Beidou, Galileo, and GLONASS. It needs to be explained that since the operating frequency ranges of the cellular network communication module and the RTK communication module are relatively close, the difficulty in sending and receiving data lies mainly in distinguishing the corresponding data of the cellular network communication module and the RTK communication module, and the operating frequency range of the WiFi communication module is higher than that of the cellular network communication module and the RTK communication module, and WiFi data is relatively easier to distinguish.
