[0002] High-frequency communication (also known as shortwave communication) is a wireless communication technology with wavelengths between 10 and 100 meters and frequencies between 3 and 30 MHz. In high-frequency communication, the propagation of signals over medium to long distances depends on ionospheric reflection, and the movement and changes in the ionosphere can cause variations in the quality of the high-frequency communication link.

[0003] However, the electron density and distribution height of the ionosphere change with sunrise and sunset and seasonal variations. Therefore, as time and seasons pass, these ionospheric changes directly impact the quality of high-frequency communication links, leading to poor stability. Currently, there is very little research on high-frequency detection technology in the industry, and how to effectively improve the stability of high-frequency communication has become a pressing technical problem that needs to be solved.

[0021] In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more, for example, multiple detection cycles means two or more detection cycles, etc.

[0022] In the process of developing this application, the inventors discovered that existing high-frequency communication has at least the following problems: a high-frequency link detection system has not been designed and developed, there is a lack of means and methods to obtain communication link quality information by implementing link detection between nodes, and it is impossible to obtain communication link quality information between communication sites and establish a communication link quality database; communication sites cannot select the best communication link for communication based on the communication link quality database when communicating, resulting in poor communication performance.

[0023] It should be noted that the various defects in the technical solutions of the prior art are the result of the inventors’ careful practical research. Therefore, the discovery process of the above problems and the solutions proposed by the embodiments of this application in the following text should be the inventors’ contributions to this application in the process of realizing this application.

[0024] The embodiments of this application are described below with reference to the accompanying drawings.

[0025] Figure 1 This is one of the flowcharts illustrating the high-frequency link detection method based on time-division multiplexing provided in this application embodiment, such as... Figure 1 As shown, it includes: Step S10: Control N stations to synchronously reside in N time slots on each detection frequency in sequence; Step S20: During the dwell period on any detection frequency, control N stations to transmit signals on the corresponding time slot according to any detection frequency in sequence, and determine all link quality information of N stations on any detection frequency; wherein, each of the N time slots is designated to have a unique station transmit signals, and N is a positive integer; Step S30: Based on all link quality information of N stations at various detection frequencies at different times, determine the optimal communication link between the stations at different times. Step S40: Before any two stations among the N stations conduct high-frequency communication, determine the target frequency for high-frequency communication between any two stations from the optimal communication links between the stations at different times.

[0026] Specifically, the N time slots described in the embodiments of this application constitute the synchronization of each station at K detection frequencies (denoted as F0, F1, ... F). K-1 The total duration ΔT of sequential residence on the [the data] is understandable, as [the data]... Figure 2 As shown, at any detection frequency F iThe dwell time ΔT seconds can be divided into N time slots, denoted as Slot0, Slot1, ..., Slot2. N-1 .

[0027] It should be noted that, in the embodiments of this application, a unique station is designated to transmit detection signals in each of the N time slots. For example, the N stations are denoted as S0, S1, ... S2. N-1 Therefore, the settings can be configured according to the correspondence between stations and time slots. That is, station S0 is configured to transmit a probe signal in time slot Slot 0, while the other N-1 stations are configured to receive the probe signal; station S1 is configured to transmit a probe signal in time slot Slot 1, while the other N-1 stations are configured to receive the probe signal; ...; station S N-1 In time slot N-1 A probe signal is transmitted, and the other N-1 stations are used to receive the probe signal.

[0028] In the embodiments of this application, in step S10, N stations S0, S1, ... S are controlled. N-1 Synchronize sequentially at each detection frequency (including F0, F1, ..., F... K-1 The dwell time ΔT is included in N time slots: Slot0, Slot1, ..., Slot2. N-1 .like Figure 3 As shown, assuming there are four detection frequencies, denoted as F0, F1, F2, and F3, we can set it so that starting from the initial time T0, all N stations switch to the first frequency F0 and stay there for ΔT seconds. After ΔT seconds, all N stations switch to the second frequency F1 and stay there for ΔT seconds. After ΔT seconds, all N stations switch to the third frequency F2 and stay there for ΔT seconds. After ΔT seconds, all N stations switch to the fourth frequency F3 and stay there for ΔT seconds. This process continues, continuously controlling the switching of detection frequencies among the N stations.

[0029] Based on the above embodiments, as an optional embodiment, time synchronization between N stations is achieved through a satellite system.

[0030] The method in this application embodiment, by keeping the time of N stations synchronized and adding a unified timestamp to the data packet by synchronizing the clock when two stations communicate, can effectively ensure that the transmission order is consistent with the sending end, which can significantly improve the accuracy of data transmission and the reliability of the communication protocol, and is conducive to further improving the stability of high-frequency communication between stations.

[0031] Based on the above embodiments, as an optional embodiment, the satellite system includes one of the BeiDou Navigation Satellite System, Global Navigation Satellite System, Global Positioning System, and Galileo Navigation Satellite System.

[0032] The method in this application embodiment can use one of the BeiDou Navigation Satellite System (BDS), Global Navigation Satellite System (GNSS), Global Positioning System (GPS), and Galileo Navigation Satellite System (GSNS) to perform time synchronization among N stations, which is beneficial to improving the adaptability and reliability of the high-frequency link detection method.

[0033] In the embodiments of this application, in step S20, a time-division multiplexing method is used. During the dwell period on any detection frequency, N stations are sequentially controlled to transmit detection signals at any detection frequency on the corresponding time slot for other stations to receive, thus establishing a high-frequency detection link between the stations. Furthermore, the link quality information of all N stations on any detection frequency is determined.

[0034] For example, during the first time slot (Slot 0), station S0 can be controlled to transmit a probe signal at frequency F0 in the first time slot (Slot 0), while the other N-1 stations receive the signal at frequency F0. This establishes N-1 high-frequency probe links, with station S0 transmitting the probe signal and the other stations receiving the signal, and the corresponding N-1 link quality information is obtained. Then, station S1 can be controlled to transmit a probe signal at frequency F0 in the second time slot (Slot 1), while the other N-1 stations receive the signal at frequency F0. This again establishes N-1 high-frequency probe links, with station S1 transmitting the probe signal and the other stations receiving the signal, and the corresponding N-1 link quality information is obtained. This process continues, traversing N time slots. When probing at frequency F0, N*(N-1) link quality information can be obtained between the N stations from the transmitting point to the receiving point. Similarly, as time progresses, all link quality information for the N stations at each probe frequency can be obtained.

[0035] Here, link quality information can be obtained by calculating the received signal-to-noise ratio, number of multipaths, multipath delay, frequency offset, etc. to characterize the link quality. The higher the signal-to-noise ratio, the fewer the number of multipaths, the smaller the delay, and the smaller the frequency offset, the higher the link quality; conversely, the lower the link quality.

[0036] Understandably, after traversing K detection frequencies, one detection cycle ends, and K*N*(N-1) links of link quality information for N stations at each detection frequency are obtained. If, after one detection cycle, the obtained communication link quality information data does not cover the pre-set detection time period, such as 24 hours a day or all year round, the collection of communication link quality information data for subsequent detection cycles can continue according to the aforementioned high-frequency link detection method until the high-frequency link detection between each station in that detection time period is completed. This yields all link quality information for N stations at each detection frequency at different times, and based on this, a communication link quality database can be established.

[0037] Furthermore, in the embodiments of this application, in step S30, when utilizing the communication link quality database, the link quality information between any two stations at different times at various detection frequencies can be obtained based on all link quality information of N stations at different times in the data block at various detection frequencies. This allows for the determination of one or more communication frequencies with better communication between the two stations, ultimately identifying one or more better communication links between them, which can be considered the optimal communication links. Similarly, the optimal communication links between stations at different times can be derived.

[0038] Furthermore, in the embodiments of this application, in step S40, before any two stations among the N stations engage in high-frequency communication, one or more optimal communication frequencies between the two stations can be identified from the best communication links between the stations at different times, and then used as the target frequencies for high-frequency communication between the two stations. Finally, the two stations can then conduct high-frequency communication according to the target frequencies, ensuring stable communication between the stations and excellent performance.

[0039] Compared to the current lack of methods for obtaining communication link quality, which prevents the acquisition of communication link quality information between communication sites and the establishment of a communication link quality database, and the inability of communication sites to select the optimal communication link based on the communication link quality database during communication; the high-frequency link detection method of this application can acquire N*(N-1) link quality information between N sites at each detection frequency, complete the establishment of a communication link quality database, and select the optimal communication link based on the communication link quality database during communication, greatly improving the high-frequency communication effect.

[0040] The high-frequency link detection method based on time division multiplexing in this application adopts time slot division to control N stations to synchronously reside in N time slots at different detection frequencies to conduct high-frequency link detection, thereby establishing a high-frequency detection link based on time division multiplexing. This allows the acquisition of all link quality information of the N stations communicating at different detection frequencies, completing the establishment of a communication link quality database. This enables the selection of the best communication link between stations based on the communication link quality database when communicating at different times and in different seasons, effectively improving the long-term stability of high-frequency communication between stations and greatly improving the high-frequency communication effect.

[0041] Based on the above embodiments, as an optional embodiment, step S20 involves sequentially controlling N stations to transmit signals at any detection frequency in the corresponding time slot during the dwell period at any detection frequency, and determining all link quality information of the N stations at any detection frequency, including: Step S1: When the dwell time on any detection frequency reaches the current time slot, control the corresponding current designated station to transmit a signal on the current time slot at any detection frequency so that the other N-1 stations can receive it and obtain the link quality information between the current designated station and the other N-1 stations. Step S2: When the dwell time on any detection frequency reaches the next time slot of the current time slot, control the designated station corresponding to the next time slot to transmit a signal on the next time slot according to any detection frequency, so that the other N-1 stations can receive it, and obtain the link quality information between the designated station corresponding to the next time slot and the other N-1 stations. Step S3: Take the next time slot as the current time slot, and repeat steps S1 and S2 until all N time slots have been traversed to obtain all link quality information of N stations at any detection frequency.

[0042] Specifically, in the embodiments of this application, the specific implementation of high-frequency link detection based on time-division multiplexing includes: Step S1: When the dwell time on any detection frequency reaches the current time slot, control the corresponding currently designated station to transmit a signal on the current time slot at any detection frequency, and the other N-1 stations receive the signal on the same frequency, thereby forming N-1 detection links, and the link quality information between the currently designated station and the other N-1 stations can be obtained.

[0043] Specifically, starting at time T0, all N stations switch to the first frequency F0 and remain stationary for ΔT seconds. Within the first time slot Slot0, the currently designated station is S0, which is controlled to transmit signals at frequency F0. The remaining N-1 stations receive signals at frequency F0. The corresponding communication links are from S0 to S1, S2, ..., S... N-1There are N-1 links, namely L[F0,(S0,S1)], L[F0,(S0,S2)], ..., L[F0,(S0,S1 ... N-1 The remaining stations S1, S2, ..., S N-1 Calculate and obtain L[F0,(S0,S1)], L[F0,(S0,S2)], ..., L[F0,(S0,S1)] based on the received signal. N-1 Link quality information.

[0044] In step S2, when the dwell time on any detection frequency reaches the next time slot of the current time slot, the designated station corresponding to the next time slot is controlled to transmit a signal on the next time slot at any detection frequency so that the other N-1 stations can receive it and obtain the link quality information between the designated station corresponding to the next time slot and the other N-1 stations.

[0045] Specifically, after entering the second time slot (Slot 1), the designated station is S1. S1 is controlled to transmit signals at frequency F0, and the remaining N-1 stations receive signals at frequency F0. The corresponding links are from S1 to S0, S2, ..., S... N-1 The N-1 links are denoted as L[F0,(S1,S0)], L[F0,(S1,S2)], ..., L[F0,(S1,S2)], ..., L[F0,(S1,S2)], respectively. N-1 S0, S2, ..., S N-1 L[F0,(S1,S0)], L[F0,(S1,S2)], ..., L[F0,(S1,S0)] are calculated and obtained based on the received signals. N-1 Link quality information.

[0046] Furthermore, steps S1 and S2 are repeated until all N time slots have been traversed. This process continues until the Nth time slot... N-1 Inside, S N-1 The signal is transmitted at frequency F0, and the remaining N-1 stations receive the signal at frequency F0; the corresponding link is from S... N-1 S0, S1, ... S N-2 The N-1 links are denoted as L[F0,(S N-1 ,S0)]、L[F0,(S N-1 ,S1)]、…、L[F0,(S N-1 ,S N-2 Other sites S0, S1, ..., S N-2 L[F0,(S) is calculated and obtained from the received signal. N-1 ,S0)]、L[F0,(S N-1 ,S1)]、…、L[F0,(S N-1 ,S N-2The link quality information of N stations at frequency F0 can be obtained.

[0047] Following this pattern, using the aforementioned high-frequency detection method, after T0+ΔT seconds, all N stations can switch to the second frequency F1 and remain stationary for ΔT seconds. Within the first time slot Slot0, S0 transmits signals on frequency F1, and the other stations receive signals on frequency F1; the corresponding links are from S0 to S1, S2, ..., S... N-1 The N-1 links are denoted as L[F1,(S0,S1)], L[F1,(S0,S2)], ..., L[F1,(S0,S1)], ... N-1 S1, S2, ..., S N-1 Calculate and obtain L[F1,(S0,S1)], L[F1,(S0,S2)], ..., L[F1,(S0,S1)] based on the received signal. N-1 Link quality information.

[0048] In the second time slot, Slot 1, S1 transmits signals at frequency F1, and the other stations receive signals at frequency F1; the corresponding links are from S1 to S0, S2, ..., S... N-1 The N-1 links are denoted as L[F1,(S1,S0)], L[F1,(S1,S2)], ..., L[F1,(S1,S2)], ..., L[F1,(S1,S2)], ... N-1 S0, S2, ..., S N-1 Calculate and obtain L[F1,(S1,S0)], L[F1,(S1,S2)], ..., L[F1,(S1,S2)] based on the received signal. N-1 Link quality information.

[0049] And so on, the Nth time slot N-1 Inside, S N-1 The signal is transmitted at frequency F1, and the other stations receive the signal at frequency F1; the corresponding link is from S... N-1 S0, S1, ..., S N-2 The N-1 links are denoted as L[F1,(S N-1 ,S0)]、L[F1,(S N-1 ,S1)]、…、L[F1,(S N-1 ,S N-2 Sites S0, S1, ..., S N-2 L[F1,(S) is calculated and obtained from the received signal. N-1 ,S0)]、L[F1,(S N-1 , S1)]、…、L[F1,(S N-1 ,S N-2 Link quality information.

[0050] And so on, starting from T0+ΔT*(K-1) seconds, all N stations switch to the Kth frequency F. K-1 The dwell time is ΔT seconds. Within the first time slot, Slot0, S0 is at frequency F. K-1 Transmit the signal, and the remaining stations at frequency F K-1 Received signal; the corresponding links are from S0 to S1, S2, ..., S... N-1 The N-1 links are denoted as L[F] K-1 ,(S0,S1)]、L[F K-1 ,(S0,S2)]、…、L[F K-1 ,(S0,S N-1 The remaining stations S1, S2, ..., S N-1 L[F] is calculated and obtained from the received signal. K-1 ,(S0,S1)]、L[F K-1 ,(S0,S2)]、…、L[F K-1 ,(S0,S N-1 Link quality information.

N-1 The N-1 links are denoted as L[F] K-1 ,(S1,S0)]、L[F K-1 ,(S1,S2)]、…、L[F K-1 ,(S1,S N-1 S0, S2, ..., S N-1 L[F] is calculated and obtained from the received signal. K-1 ,(S1,S0)]、L[F K-1 ,(S1,S2)]、……L[F K-1 ,(S1,S N-1 Link quality information.

[0052] And so on, the Nth time slot N-1 Inside, S N-1 At frequency F K-1 Transmit the signal, and the remaining stations at frequency F K-1 Receive signal; the corresponding link is from S N-1 S0, S1, ..., S N-2 The N-1 links are denoted as L[F] K-1 ,(S N-1 ,S0)]、L[FK-1 ,(S N-1 ,S1)]、……L[F K-1 ,(S N-1 ,S N-2 The remaining stations S0, S1, ..., S N-2 Calculate and obtain L[F] based on the received signal. K-1 ,(S N-1 ,S0)]、L[F K-1 ,(S N-1 ,S1)]、…、L[F K-1 ,(S N-1 ,S N-2 The link quality information is obtained by iterating through K probe frequencies. After that, one probe cycle ends.

[0053] The method in this application adopts a time-division multiplexing link detection approach, which sequentially traverses and performs high-frequency detection at each site, time slot, and detection frequency. This can increase the capacity of the high-frequency link detection system, increase the number of detected links, and provide rich technical data for the subsequent establishment of a communication link quality database.

[0054] Based on the above embodiments, as an optional embodiment, before determining the optimal communication link between N stations at different times based on all link quality information of N stations at various detection frequencies in step S3, the method further includes: After traversing all detection frequencies until the end of the current detection period, obtain all link quality information of N stations at each detection frequency in the current detection period; The algorithm iterates through each detection frequency until it obtains all link quality information for N sites within the target time period. The target time period includes the current detection cycle and multiple subsequent detection cycles. Based on the link quality information of N sites during the target time period, the link quality information of N sites at each detection frequency at different times during the target time period is obtained.

[0055] Specifically, the target time period described in the embodiments of this application refers to the total time period of high-frequency link detection that is set in advance. It can be composed of multiple detection cycles, such as 24 hours a day, a month, or a year, and can be freely set in advance according to the actual high-frequency detection needs.

[0056] In the embodiments of this application, before determining the optimal communication link between the stations at different times based on all link quality information of N stations at each detection frequency at different times in step S3, it is also necessary to pre-determine all link quality information of N stations at each detection frequency at different times.

[0057] More specifically, in the embodiments of this application, after the end of a detection cycle, time continues to advance to T0+ΔT*K seconds, and N stations can be controlled to switch back to the first frequency F0 and stay there for ΔT seconds, and the detection process on the F0 frequency can be repeated according to the steps of the aforementioned embodiments.

[0058] When the time reaches T0+ΔT*(K+1) seconds, continue to control N stations to switch to the second frequency F1 again and stay for ΔT seconds. Similarly, the detection process on the F1 frequency can be repeated according to the steps of the aforementioned embodiment.

[0059] Similarly, N stations use time-division multiplexing on K frequencies to cyclically probe and record the quality information of each link. By continuously executing the aforementioned probe steps, the link quality information between each station can be obtained for 24 hours a day, and the link quality information for each link throughout the year. This allows the establishment of a communication link quality database for high-frequency communication links between various stations.

[0060] The method in this application embodiment, based on time-division multiplexing high-frequency link detection technology, performs cyclic detection between different stations on the time axis, which can accumulate link quality information of each communication link throughout the day or even the whole year, effectively realizing the establishment of a communication link quality database and providing the best link reference for subsequent high-frequency communication between stations.

[0061] Based on the above embodiments, as an optional embodiment, step S4, before any two stations among the N stations conduct high-frequency communication, determines the target frequency for high-frequency communication between any two stations from the optimal communication links between each station at different times, including: Before any two stations out of N stations can conduct high-frequency communication, determine the target time for the high-frequency communication between any two stations. From the best communication links between various stations at different times, determine the target best communication link between any two stations within the time period corresponding to the target time. Based on the target optimal communication link, the target frequency for high-frequency communication between any two stations is obtained.

[0062] Specifically, in the embodiments of this application, before any two stations out of N stations conduct high-frequency communication, the target time for the high-frequency communication between the two stations is first determined. For example, if station A and station B specify that they will start high-frequency communication at 4 PM on a certain day, then the target time is 4 PM on that day.

[0063] In the embodiments of this application, by utilizing the pre-determined optimal communication links between various stations at different times, the target optimal communication link between any two stations within a time period corresponding to the target time can be further determined. For example, if the target time is 4 PM on a certain day, the optimal communication link between station A and station B at 4 PM on a corresponding historical day can be determined, which is the target optimal communication link between station A and station B.

[0064] Furthermore, in the embodiments of this application, the communication frequency used on the target optimal communication link can be directly determined based on the target optimal communication link, that is, the target frequency for high-frequency communication between any two stations can be obtained.

[0065] For example, consider two nodes, site A and site B. By probing and calculating the link quality information between site A and site B and storing it in a database, and through 24-hour cyclical probing, one day's link information data between the two sites can be obtained. Continuing with cyclical probing, one year's link information data between the two sites can be obtained. When site A and site B need to communicate, both can query the link quality information database at any time and retrieve the target frequency corresponding to the target time of communication. For example, if the target time for communication between the two sites is "November 19, 2025, 15:10", then the historical link quality information records for the period "November 18, 2025, 15:00-15:30" can be retrieved from the data block, and four target frequencies with better quality can be selected for communication. These four frequencies can be considered the optimal communication frequencies for the site A-site B link at the current time.

[0066] The method in this application embodiment, based on an established communication link quality database, can quickly select the corresponding target optimal communication link from the database for communication when communication stations are communicating, according to the current time and communication object, which can further effectively improve the effect and efficiency of high-frequency communication between stations.
