Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to a method, device, equipment and medium for long-distance shipping wireless communications. Background Art

[0002] With the continuous improvement of coastal 5G (5th Generation Mobile Communication Technology) base station planning and construction, mobile phones and wireless data terminals can access 5G base station services on fishing boats and cruise ships about 10 km from the coast. However, when the offshore distance reaches 10 to 50 km, the mobile phones and wireless data terminals on the ship cannot effectively access the 5G base station services.

[0003] In order to solve the above technical problems, the existing technology usually realizes wireless communication for long-distance shipping through satellite phones or satellite data transmission communication equipment. Among them, the use cost of satellite phones is relatively high, and satellite data transmission communication equipment requires an antenna servo system to ensure that the antenna points to the satellite direction. The equipment is expensive and bulky, and the use cost is also high. For the actual application of ordinary fishing boats or cruise ships, the above method is not applicable.

[0004] Therefore, how to solve the wireless communication problem of long-distance shipping in navigation and turning scenarios at low cost is a technical problem that needs to be solved at present. Summary of the invention

[0005] The present application provides a long-distance shipping wireless communication method, device, equipment and medium to solve the technical problem of how to reduce the wireless communication hardware cost of long-distance shipping in navigation and turning scenarios.

[0006] In order to solve the above technical problems, in the first aspect, the embodiment of the present application provides a long-distance shipping wireless communication method, which is applied to a terminal, wherein the terminal comprises: a directional antenna array and a 5G transceiver unit; the directional antenna array comprises a plurality of antennas; the 5G transceiver unit comprises at least three radio frequency transceiver interfaces; the wireless communication method comprises:

[0007] Control two of the radio frequency transceiver interfaces to connect to the antennas in the directional antenna array to enter a communication state, and calculate in real time first signal quality values ​​of the corresponding antennas in the directional antenna array;

[0008] Control the remaining radio frequency transceiver interfaces to enter a network search state, so as to calculate in real time the second signal quality values ​​of the remaining unconnected antennas in the directional antenna array;

[0009] According to each of the first signal quality values ​​and each of the second signal quality values, the state of each of the radio frequency transceiver interfaces is switched so that the radio frequency transceiver interface in the communication state remains connected to the antenna with the highest signal quality.

[0010] Compared with the prior art, the embodiment of the present application has the following beneficial effects: through at least three RF transceiver interfaces in the 5G transceiver unit, two of which are used for data communication, and the other RF transceiver interfaces are used for antenna signal quality evaluation, so that during the data communication process, even if the ship changes direction, the antenna with the correct satellite orientation can still be determined according to the signal quality, thereby better balancing the communication and handshake between the antenna and the base station over a long distance, and reducing the hardware cost during the wireless communication process. In addition, since two RF transceiver interfaces are used for data communication, the terminal is forced to be in 2T2R (Two Transmit & Two Rece i ve) mode, thereby supporting higher spectrum efficiency and lower bit error rate during long-distance communication, and improving the stability of the signal during subsequent wireless communication.

[0011] In some embodiments of the first aspect of the present application, switching the state of each of the radio frequency transceiver interfaces according to the first signal quality value and the second signal quality value includes:

[0012] When there is at least one second signal quality value that exceeds the minimum first signal quality value by a first preset value and is maintained for a first preset time,

[0013] The RF transceiver interface in the network searching state is connected to the antenna corresponding to the largest second signal quality value, so that the RF transceiver interface is switched to the communication state, and the RF transceiver interface connected to the antenna corresponding to the smallest first signal quality value is switched to the network searching state.

[0014] Compared with the prior art, the above embodiment has the following beneficial effects: during the navigation of a ship, there may be an instantaneous azimuth deviation caused by wind and waves, so at this time it may appear that a second signal quality value exceeds the first signal quality value in an instant. In order to prevent erroneous antenna switching behavior in the above situation, it is necessary to ensure that the second signal quality value exceeds the minimum first signal quality value for a certain period of time, and needs to exceed a certain preset value. At this time, antenna switching can maximize the correctness of the antenna switching behavior, thereby improving the signal quality.

[0015] In some embodiments of the first aspect of the present application, when the state of each of the RF transceiver interfaces is switched, it also includes: during the antenna switching process, maintaining at least one of the RF transceiver interfaces in a communication state.

[0016] Compared with the prior art, the above embodiment has the following beneficial effects: when there are multiple RF transceiver interfaces in the network search state, the second signal quality values ​​corresponding to two unconnected antennas may be greater than the first signal quality values ​​at the same time. At this time, if the switching process of the antennas in the communication state overlaps, it will cause the communication to be disconnected in a certain period of time, making the communication state unstable. Therefore, by maintaining at least one RF transceiver interface in the communication state during the antenna switching process, the stability of long-distance shipping wireless communication can be effectively improved.

[0017] In some embodiments of the first aspect of the present application, controlling the remaining radio frequency transceiver interfaces to enter a network search state to calculate in real time the second signal quality values ​​of the remaining unconnected antennas in the directional antenna array, includes:

[0019] When the remaining radio frequency transceiver interfaces are connected to the remaining unconnected antennas in the directional antenna array, the second signal quality value corresponding to the antenna is measured and obtained.

[0020] Compared with the prior art, the above embodiment has the following beneficial effects: by controlling the remaining RF transceiver interfaces to queue and switch the connections of the unconnected antennas and measure the second signal quality values, the real-time performance of all antenna signal quality monitoring is improved, the antenna with the highest signal quality is quickly locked, and the effect of long-distance shipping wireless communication is further improved.

[0021] In some embodiments of the first aspect of the present application, the directional antenna array is composed of antenna pairs in four directions of east, south, west and north, and each of the antenna pairs includes two antennas in the same direction.

[0022] Compared with the prior art, the above embodiment has the following beneficial effects: since there is an antenna pair in each orientation and each antenna pair consists of two antennas, when two RF transceiver interfaces are used for data communication, the two antennas connected in the same direction or in different directions can support higher spectrum efficiency and lower bit error rate. At the same time, the above antenna array structure can provide spatial multiplexing and diversity gain, thereby improving the stability and transmission rate of long-distance shipping wireless communication signals.

[0023] In some embodiments of the first aspect of the present application, the terminal communicates in 2T2R mode.

[0024] Compared with the prior art, the above embodiments have the following beneficial effects: in the 2T2R mode, since the communication work is undertaken by two RF transceiver interfaces, the two RF transceiver interfaces need to undertake data reception and transmission at the same time, thereby improving the spatial multiplexing and diversity gain of the device. At the same time, in the 5G network, the 2T2R mode can support higher spectrum efficiency and lower bit error rate, thereby improving the stability and transmission rate of long-distance shipping wireless communication signals.

[0025] In some embodiments of the first aspect of the present application, the terminal also includes an IP voice and alarm unit and a Wi-Fi and network port unit; the IP voice and alarm unit is used to output and receive shipping data; the Wi-Fi and network port unit is connected to the 5G transceiver unit to establish a communication channel for the IP voice and alarm unit.

[0026] Compared with the prior art, the above embodiment has the following beneficial effects: through Wi-Fi and the network port unit, it can provide convenient network access function for users on the ship, and at the same time cooperate with the IP voice and alarm unit to effectively improve the safety of the ship during long-distance navigation.

[0027] In a second aspect, an embodiment of the present application further provides a long-distance shipping wireless communication device, which is applied to a terminal, wherein the terminal comprises: a directional antenna array and a 5G transceiver unit; the directional antenna array comprises a plurality of antennas; the 5G transceiver unit comprises at least three radio frequency transceiver interfaces; the wireless communication device comprises: a first signal quality value calculation module, a second signal quality value calculation module and a radio frequency transceiver interface switching module;

[0028] The first signal quality value calculation module is used to control two of the RF transceiver interfaces to be connected to the antennas in the directional antenna array, enter a communication state, and calculate in real time the first signal quality values ​​of the corresponding antennas in the directional antenna array;

[0029] The second signal quality value calculation module is used to control the remaining radio frequency transceiver interfaces to enter a network search state, so as to calculate in real time the second signal quality values ​​of the remaining unconnected antennas in the directional antenna array;

[0030] The RF transceiver interface switching module is used to switch the state of each RF transceiver interface according to each first signal quality value and each second signal quality value, so that the RF transceiver interface in the communication state remains connected to the antenna with the highest signal quality.

[0036] At present, the existing technology usually realizes wireless communication for long-distance shipping through satellite phones or satellite data transmission communication equipment. Among them, the use cost of satellite phones is relatively high, and satellite data transmission communication equipment requires an antenna servo system to ensure that the antenna points to the satellite direction. The equipment is expensive and bulky, and the use cost is also high. For the actual application of ordinary fishing boats or cruise ships, the above method is not applicable.

[0037] In order to solve the above technical problems, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Embodiment 1

[0039] Please refer to Figure 1 , a long-distance shipping wireless communication method provided in an embodiment of the present application is applied to a terminal, wherein the terminal includes: a directional antenna array and a 5G transceiver unit; the directional antenna array includes a plurality of antennas; the 5G transceiver unit includes at least three radio frequency transceiver interfaces.

[0040] Furthermore, in some embodiments of the present application, the directional antenna array is composed of antenna pairs in four directions of east, south, west and north, and each of the antenna pairs includes two antennas in the same direction.

[0041] Since there is an antenna pair in each orientation and each antenna pair consists of two antennas, when two RF transceiver interfaces are used for data communication, the two antennas connected in the same direction or in different directions can support higher spectrum efficiency and lower bit error rate. At the same time, the above antenna array structure can provide spatial multiplexing and diversity gain, thereby improving the stability and transmission rate of long-distance shipping wireless communication signals.

[0042] Furthermore, in some embodiments of the present application, the terminal also includes an IP voice and alarm unit and a Wi-Fi and network port unit; the IP voice and alarm unit is used to output and receive shipping data; the Wi-Fi and network port unit is connected to the 5G transceiver unit to establish a communication channel for the IP voice and alarm unit.

[0043] Through Wi-Fi and network port units, convenient network access functions can be provided for users on the ship. At the same time, combined with IP voice and alarm units, the safety of ships during long-distance navigation can be effectively improved.

[0044] Preferably, in some embodiments of the present application, the IP voice and alarm unit is also used for screen display of weather forecasts and wireless broadband signal to audio output, providing an interface for emergency command platforms such as maritime management agencies and fishery administrative departments to display or voice forecast natural disasters such as typhoons, earthquakes, tsunamis, and assist in the command and dispatch of offshore vessels, while providing ships with functions such as reporting position, heading, and emergencies, to facilitate the collection, management and emergency rescue of information.

[0045] Preferably, reference Figure 2 , is a terminal for applying a long-distance shipping wireless communication method provided in some embodiments of the present application. Figure 2 As shown, the directional antenna array may adopt a high-gain directional antenna array unit, which is composed of antenna pairs in four directions of east, south, west and north, and each antenna pair is two antennas in the same direction, and the gain of each antenna is ≥18.5dBi. Figure 2The terminal shown also includes an eight-choice electronic switch, a 5G transceiver unit, a Wi-Fi and network port unit, and an IP voice and alarm unit; wherein the eight-choice electronic switch is electrically connected to the eight antennas in the high-gain directional antenna array unit, the eight-choice electronic switch is electrically connected to the four RF transceiver interfaces (i.e., TR0, TR1, TR2, and TR3) in the 5G transceiver unit, the Wi-Fi and network port unit is electrically connected to the 5G transceiver unit, and the IP voice and alarm unit is electrically connected to the Wi-Fi and network port unit, wherein the IP voice and alarm unit is also configured with a sensor interface, a voice interface, and an alarm control interface.

[0046] As another preferred embodiment, the directional antenna array may also be arranged in a 360-degree uniform distribution.

[0047] Furthermore, in some embodiments of the present application, the terminal communicates using a 2T2R mode.

[0048] In the 2T2R mode, since the communication work is undertaken by two RF transceiver interfaces, the two RF transceiver interfaces need to undertake data reception and transmission at the same time, thereby improving the spatial multiplexing and diversity gain of the equipment. At the same time, in the 5G network, the 2T2R mode can support higher spectrum efficiency and lower bit error rate, thereby improving the stability and transmission rate of long-distance shipping wireless communication signals.

[0049] Further, in some embodiments of the present application, the wireless communication method includes S10 to S30, specifically:

[0050] S10: Control two of the radio frequency transceiver interfaces to connect to the antennas in the directional antenna array to enter a communication state, and calculate in real time first signal quality values ​​of the correspondingly connected antennas in the directional antenna array.

[0051] Preferably, in some embodiments of the present application, any signal quality value can be evaluated using indicators such as RSRP (Reference Signal Received Power). The present application does not limit the indicator, but the first signal quality value and the second signal quality value should use the same indicator.

[0052] S20: Control the remaining radio frequency transceiver interfaces to enter a network search state, so as to calculate in real time the second signal quality values ​​of the remaining unconnected antennas in the directional antenna array.

[0053] Further, in some embodiments of the present application, controlling the remaining radio frequency transceiver interfaces to enter a network search state to calculate in real time the second signal quality values ​​of the remaining unconnected antennas in the directional antenna array includes:

[0054] Controlling at least one of the remaining radio frequency transceiver interfaces to switch in turn the connection relationship with the remaining unconnected antennas in the directional antenna array;

[0055] When the remaining radio frequency transceiver interfaces are connected to the remaining unconnected antennas in the directional antenna array, the second signal quality values ​​corresponding to the antennas are measured and acquired.

[0056] By controlling the remaining RF transceiver interfaces, the unconnected antennas are queued for switching and connecting and measuring the second signal quality values, thereby improving the real-time performance of all antenna signal quality monitoring, quickly locking the antenna with the highest signal quality, and further improving the effect of long-distance shipping wireless communication.

[0057] Preferably, reference Figure 2 In some embodiments of the present application, when the RF transceiver interface in the network search state calculates the second signal quality value of the remaining unconnected antennas, the electronic switch control controls the switches in the eight-choice four electronic switches to be closed or connected, thereby measuring the second signal quality value of each unconnected antenna in turn. When there are multiple RF transceiver interfaces, a fixed antenna monitoring object can be set for each RF transceiver interface. For example, when TR2 and TR3 are in the network search state, TR2 can perform a search operation only from the unconnected antennas among antenna 1, antenna 3, antenna 5, and antenna 7, and TR3 can perform a search operation only from the unconnected antennas among antenna 2, antenna 4, antenna 6, and antenna 8, where the relative position relationship between antenna 1 to antenna 8 is: Figure 2 The order shown is close to each other, and the purpose of this is to improve the signal search efficiency.

[0058] S30: Switching the state of each of the RF transceiver interfaces according to each of the first signal quality values ​​and each of the second signal quality values, so that the RF transceiver interface in the communication state remains connected to the antenna with the highest signal quality.

[0059] Further, in some embodiments of the present application, switching the state of each of the radio frequency transceiver interfaces according to the first signal quality value and the second signal quality value includes:

[0060] When there is at least one second signal quality value that exceeds the first preset value of the minimum first signal quality value and is maintained for a first preset time, the RF transceiver interface in the network searching state is connected to the antenna corresponding to the maximum second signal quality value, so that the RF transceiver interface is switched to the communication state, and the RF transceiver interface connected to the antenna corresponding to the minimum first signal quality value is switched to the network searching state.

[0061] During the voyage of a ship, there may be an instantaneous azimuth deviation caused by wind and waves. Therefore, a second signal quality value may exceed the first signal quality value in an instant. In order to prevent erroneous antenna switching behavior in the above situation, it is necessary to ensure that the second signal quality value exceeds the minimum first signal quality value for a certain period of time and exceeds a certain preset value. At this time, antenna switching can maximize the correctness of the antenna switching behavior, thereby improving the signal quality.

[0062] by Figure 2 Take TR2 as an example, and based on the following assumption 1: currently only TR2 is in the network searching state, TR0 and TR1 are in the communication state, TR0 communicates with antenna 1, and TR1 communicates with antenna 2, that is, two RF transceiver interfaces are in the communication state, and only one RF transceiver interface is in the network searching state.

[0063] Based on the above assumption 1, in one of the preferred embodiments of the present application, after TR2 measures the second signal quality values ​​of all remaining unconnected antennas, it selects the largest second signal quality value and compares it with the smallest first antenna quality value of antenna 1 and antenna 2 to make subsequent antenna switching judgments. Assume that the current antenna 3 is the antenna with the largest second signal quality value of all remaining unconnected antennas. Then TR2 is connected to antenna 3 again, and the second signal quality value of antenna 3 is continuously measured. When the second signal quality value of antenna 3 is greater than the smallest first antenna quality value of antenna 1 and antenna 2 by 3dB, and lasts for more than 3 seconds, the connection state of TR2 and the antenna is maintained, which is equivalent to making TR2 directly enter the communication state, while disconnecting the connection state of TR0 or TR1 corresponding to the smallest first antenna quality value and the antenna, and making TR0 or TR1 disconnected from the antenna enter the network search state, thereby ensuring that the antenna with the best signal quality is selected.

[0064] Based on the above assumption one, in one of the preferred embodiments of the present application, when TR2 connects the remaining unconnected antennas in sequence to measure the second signal quality value, if the second signal quality value corresponding to the antenna currently connected is already greater than the smallest first antenna quality value of antenna 1 and antenna 2 by 3dB, then the connection state of TR2 and the antenna is maintained for 3 seconds. If during the 3 seconds, the second signal quality value corresponding to the antenna currently connected continues to be greater than the smallest first antenna quality value of antenna 1 and antenna 2 by 3dB, then TR2 enters the communication state, and at the same time, the connection state between TR0 or TR1 corresponding to the smallest first antenna quality value and the antenna is disconnected, and TR0 or TR1 disconnected from the antenna enters the network search state, thereby progressively improving the signal quality and reducing signal fluctuations.

[0065] by Figure 2Take for example, and based on the following assumption 2: currently TR2 and TR3 are in the network searching state, TR0 and TR1 are in the communication state, TR0 communicates with antenna 1, and TR1 communicates with antenna 2, that is, two RF transceiver interfaces are in the communication state, and multiple RF transceiver interfaces are in the network searching state.

[0066] Based on the above assumption 2, in one of the preferred embodiments of the present application, TR2 cooperates with TR3, and after measuring the second signal quality values ​​of all remaining unconnected antennas, the largest second signal quality value is selected to compare with the smallest first antenna quality value of antenna 1 and antenna 2 to make subsequent antenna switching judgments. Assume that the current antenna 3 is the antenna with the largest second signal quality value of all remaining unconnected antennas, and the antenna 3 searched is TR2. Then TR2 is connected to antenna 3 again, and the second signal quality value of antenna 3 is continuously measured. When the second signal quality value of antenna 3 is greater than the smallest first antenna quality value of antenna 1 and antenna 2 by 3dB, and lasts for more than 3 seconds, a switching operation similar to the above assumption 1 is performed. During the process of TR2 and antenna 3 being connected again, TR3 performs a network search operation in parallel to improve the network search efficiency.

[0067] Based on the above assumption 2 and the preferred embodiment of the above assumption 2, when TR2 and TR3 cooperate to simultaneously measure the second signal quality values ​​of all remaining unconnected antennas, the antennas that TR2 and TR3 need to search can be fixed in advance, and one antenna in each azimuth is allocated to TR2 and TR3, that is, TR2 only performs the search operation from antenna 3, antenna 5, and antenna 7, and TR3 only performs the search operation from antenna 4, antenna 6, and antenna 8. Since each antenna pair is two antennas in the same direction, such as Figure 2 As shown, assuming that among all antennas in different directions, when antenna 3 has the highest signal quality, another antenna with higher signal quality is most likely the antenna in the same direction as antenna 3 or the antenna in a different direction closest to antenna 3, namely antenna 2 and antenna 4. When TR2 performs a 3-second connectivity test for the second signal quality value, it will not affect TR3's simultaneous 3-second connectivity test process. Therefore, the above-mentioned pre-fixed method cross-fixes the antennas searched by the two RF interfaces in the sequentially arranged antenna array, thereby improving the efficiency of subsequent antenna switching.

[0068] Based on the above assumption 2, in one of the preferred embodiments of the present application, TR2 cooperates with TR3 to queue up to perform the network search operation. For example, TR2 first performs the network search operation (the network search operation here can adopt any one of the operations in assumption 1). When TR2 performs the search operation, it takes a certain amount of time to determine whether the antenna meets the network switching condition (that is, the second signal quality value of one of the antennas is greater than the smallest first antenna quality value of antenna 1 and antenna 2 by 3dB, and it lasts for more than 3 seconds). Therefore, during the continuous measurement period of 3 seconds, TR2 starts to perform the network search operation, thereby ensuring that at least one RF transceiver interface is in the network search state at any time. When TR2 enters the communication state, it is assumed that TR0 switches to the network search state at this time. At this time, TR3 first performs the network search operation of TR2, and TR0 starts to perform the network search operation during the continuous measurement period of 3 seconds performed by TR2, and so on.

[0069] Furthermore, in some embodiments of the present application, when the state of each of the RF transceiver interfaces is switched, it also includes: during the antenna switching process, maintaining at least one of the RF transceiver interfaces in a communication state.

[0070] When there are multiple RF transceiver interfaces in the network search state, it is possible that the second signal quality values ​​corresponding to two unconnected antennas are greater than the first signal quality values ​​at the same time. At this time, if the switching process of the antennas in the communication state overlaps, it will cause the communication to be disconnected for a certain period of time, making the communication state unstable. Therefore, by maintaining at least one RF transceiver interface in the communication state during the antenna switching process, the stability of long-distance shipping wireless communication can be effectively improved. At the same time, when the ship changes direction or receives signals from other base stations, the signal quality of each antenna changes the most. Therefore, in order to prevent the network from being disconnected due to erroneous judgment, the two RF transceiver interfaces in the communication state cannot be switched at the same time.

[0071] In summary, a long-distance shipping wireless communication method provided in the embodiment of the present application has the following beneficial effects: through at least three RF transceiver interfaces in the 5G transceiver unit, two of which are used for data communication, and the other RF transceiver interfaces are used for antenna signal quality evaluation, so that in the process of data communication, even if the ship changes direction, the antenna with the correct satellite orientation can still be determined according to the signal quality, so as to better balance the communication and handshake between the antenna and the base station over a long distance, and reduce the hardware cost in the process of wireless communication. In addition, since two RF transceiver interfaces are used for data communication, the terminal is forced to be in 2T2R mode, thereby supporting higher spectrum efficiency and lower bit error rate during long-distance communication, and improving the stability of the signal during subsequent wireless communication.
