Description

Technical Field

[0001] The present invention belongs to the field of satellite technology, and in particular relates to an autonomous, controllable, anti-interference timing method and device based on Beidou. Background Art

[0002] In order to achieve anti-interference processing of satellites during the time synchronization process, the invention patent application CN202411455266.5 "A Beidou high-precision intelligent navigation method and system" records the timestamps of the base station and the mobile terminal and calculates the time error for real-time correction, analyzes the error change trend within a fixed time period, and thus determines the correction strategy. However, the above technical solutions all have the following technical problems: At present, all time synchronization equipment obtains time, position and frequency through satellite navigation systems. However, satellite navigation signals are easily interfered with intentionally or unintentionally, resulting in wrong time and position. For time synchronization equipment, its security will directly affect the information security and system security of its application field, which means that the use of a single time synchronization mode may not meet the reliability requirements of time synchronization processing.

[0003] In response to the above technical problems, the present application specifically provides an autonomous, controllable, and anti-interference timing method and device based on Beidou. Summary of the invention

[0004] To achieve the purpose of the present invention, the present invention adopts the following technical solutions: In the first aspect, the present application provides an autonomous and controllable anti-interference timing method based on Beidou, which specifically includes: S1 determines the distribution data of the time synchronization deviation period of the time synchronization mode on different dates based on the deviation of the historical time synchronization processing results in different time periods according to different time synchronization modes in the Beidou time synchronization device; S2, based on the distribution data of different synchronization modes in the synchronization deviation periods on different dates, if it is determined that there is no synchronization mode that meets the synchronization processing reliability requirements, proceed to the next step; S3: obtaining distribution data of different time periods in which different time synchronization modes are identified as time synchronization deviation time periods, and using the distribution data identified as time synchronization deviation time periods to determine the time synchronization processing time periods and time synchronization processing priorities in the time periods, and using the time synchronization processing priorities to determine the priority time synchronization processing time periods; S4 obtains the time synchronization processing results of different time synchronization modes in the priority time synchronization processing period, and determines the need for correction processing of the target device in combination with the distribution data of the time synchronization deviation periods of different time synchronization modes in the priority time synchronization processing period. Then, the adjustment processing strategy of the priority time synchronization processing period is determined according to the correction processing data in the priority time synchronization processing period and the time synchronization processing priority.

[0005] The beneficial effects of the present invention are: By obtaining the time synchronization results of different time synchronization modes in the priority time synchronization processing period and the distribution data of the time deviation periods of different time synchronization modes in the priority time synchronization processing period, it is determined whether it is necessary to perform correction processing on the target device, thereby realizing correction processing on the target device based on multiple time synchronization modes, avoiding the technical problem of insufficient reliability of time synchronization processing caused by adopting a single time synchronization mode, and further combining the distribution data of the time deviation periods of different time synchronization modes in the priority time synchronization processing period, fully considering the data credibility of different time synchronization modes, and ensuring the reliability of the time synchronization processing results.

[0006] The adjustment processing strategy of the priority time synchronization processing period is determined based on the correction processing data in the priority time synchronization processing period and the time synchronization processing priority, thereby avoiding the occurrence of technical problems such as unreliable time synchronization results caused by deviations in the time synchronization data between different time synchronization modes in the priority time synchronization processing period, and automatically adjusting the priority time synchronization processing period, thereby improving the reliability of the time synchronization processing of the target device.

[0007] A further technical solution is that the time synchronization mode includes a satellite navigation positioning system, a long wave mode, and a short wave mode.

[0008] A further technical solution is that the time synchronization deviation period is a period during which there is a deviation between the time synchronization processing result and the actual time synchronization result.

[0009] A further technical solution is to determine whether the time synchronization processing reliability of the time synchronization mode meets the requirements, specifically including: Based on the distribution data of the time synchronization deviation periods on different dates of the time synchronization mode, the number of times different time periods are identified as time synchronization deviation periods is determined, and the number of times the time synchronization deviation is used as the number of time synchronization deviations; Determining deviation coefficients for different time periods based on a ratio of the number of time synchronization deviations to the number of time synchronization processing in the time period; Whether the time synchronization processing reliability of the time synchronization mode meets the requirements is determined according to the deviation coefficients of different time periods.

[0010] A further technical document is that when there is a period in which the deviation coefficient is less than a preset deviation coefficient, it is determined that the reliability of the time synchronization processing of the time synchronization mode meets the requirements.

[0011] A further technical solution is to determine whether the time synchronization processing reliability of the time synchronization mode meets the requirements, specifically including: Based on the distribution data of the time synchronization deviation periods on different dates of the time synchronization mode, the number of times different time periods are identified as time synchronization deviation periods is determined, and the number of times the time synchronization deviation is used as the number of time synchronization deviations; Whether the time synchronization processing reliability of the time synchronization mode meets the requirement is determined based on the number of time synchronization deviations in different time periods.

[0012] A further technical solution is that, when there is a period in which the number of time synchronization deviations is within a preset deviation number interval, it is determined that the time synchronization processing reliability of the time synchronization mode meets the requirements.

[0013] A further technical solution is that the method for determining the adjustment processing strategy of the priority time synchronization processing period is: Determine the number of deviations between the time synchronization processing results of different time synchronization modes in the priority time synchronization processing period based on the processing results of different time synchronization modes at any time in the priority time synchronization processing period, and use it as the number of data deviations; The number of time synchronization processing times in the priority time synchronization processing period is used as the matching time synchronization processing times; The proportion of the number of data deviations in the number of matching time synchronization processing times is used as a time synchronization deviation factor, and the adjustment processing strategy of the priority time synchronization processing period is determined by using the time synchronization deviation factor and the time synchronization processing priority.

[0014] A further technical solution is to use the timing deviation factor and the timing processing priority to determine the adjustment processing strategy of the priority timing processing period, specifically including: When the timing deviation factor is less than a preset deviation factor threshold, it is determined that there is no need to adjust the priority timing processing period; When the timing deviation factor is not less than the preset deviation factor threshold, the priority timing processing period is adjusted and the priority timing processing period is switched to a timing processing period with the highest timing processing priority other than the priority timing processing period.

[0022] Example 1 To solve the above problems, according to one aspect of the present invention, Figure 1 As shown, according to one aspect of the present invention, an autonomous and controllable anti-interference timing method based on Beidou is provided, which specifically includes: S1 determines the distribution data of the time synchronization deviation period of the time synchronization mode on different dates based on the deviation of the historical time synchronization processing results in different time periods according to different time synchronization modes in the Beidou time synchronization device; Furthermore, the timing modes include a satellite navigation positioning system, a long-wave mode, and a short-wave mode.

[0023] Specifically, the time synchronization deviation period is a period during which there is a deviation between the time synchronization processing result and the actual time synchronization result.

[0024] S2, based on the distribution data of different synchronization modes in the synchronization deviation periods on different dates, if it is determined that there is no synchronization mode that meets the synchronization processing reliability requirements, proceed to the next step; It should be noted that if Figure 2As shown, judging whether the time synchronization processing reliability of the time synchronization mode meets the requirements includes: Based on the distribution data of the time synchronization deviation periods on different dates of the time synchronization mode, the number of times different time periods are identified as time synchronization deviation periods is determined, and the number of times the time synchronization deviation is used as the number of time synchronization deviations; Determining deviation coefficients for different time periods based on a ratio of the number of time synchronization deviations to the number of time synchronization processing in the time period; Whether the time synchronization processing reliability of the time synchronization mode meets the requirements is determined according to the deviation coefficients of different time periods.

[0025] Further, when there is a period in which the deviation coefficient is less than the preset deviation coefficient, it is determined that the time synchronization processing reliability of the time synchronization mode meets the requirement.

[0026] Optionally, judging whether the time synchronization processing reliability of the time synchronization mode meets the requirements includes: Based on the distribution data of the time synchronization deviation periods on different dates of the time synchronization mode, the number of times different time periods are identified as time synchronization deviation periods is determined, and the number of times the time synchronization deviation is used as the number of time synchronization deviations; Whether the time synchronization processing reliability of the time synchronization mode meets the requirement is determined based on the number of time synchronization deviations in different time periods.

[0027] It should be noted that when there is a period in which the number of time synchronization deviations is within a preset deviation number interval, it is determined that the time synchronization processing reliability of the time synchronization mode meets the requirement.

[0028] In another possible embodiment, determining whether the time synchronization processing reliability of the time synchronization mode meets the requirement specifically includes: S11 determines the date with the time deviation period based on the distribution data of the time deviation period of the time synchronization mode on different dates, and uses it as the time deviation date, and determines the basic deviation coefficient of the time synchronization mode according to the ratio of the time deviation times to the time synchronization processing times of different time deviation dates and the proportion of the number of time deviation dates; S12, based on the distribution data of the time deviation periods of the time synchronization mode on different dates, determining the number of times different time periods are identified as time deviation periods, and using it as the number of time deviations, and combining the ratio of the number of time deviations to the number of time synchronization processing in the time period to determine the time deviation coefficients of the different time periods; S13 determines the comprehensive deviation coefficients of different time periods according to the product of the time synchronization deviation coefficients of different time periods and the basic deviation coefficients, and uses the comprehensive deviation coefficients of different time periods to determine whether the time synchronization processing reliability of the time synchronization mode meets the requirements.

[0029] Further, when there is a time period in which the comprehensive deviation coefficient meets the requirement, it is determined that the time synchronization processing reliability of the time synchronization mode meets the requirement.

[0030] It should be noted that, when there is a time synchronization mode whose time synchronization processing reliability meets the requirement, the time synchronization mode with the highest time synchronization processing reliability is used to perform time synchronization processing on the target device.

[0031] Optionally, the above step S11 includes the following contents: S111 determines the total number of the time deviation periods of the time synchronization mode based on the distribution data of the time deviation periods of the time synchronization mode on different dates. When the total number of the time deviation periods of the time synchronization mode is greater than the preset number of deviation periods, it is determined that the time synchronization processing reliability of the time synchronization mode does not meet the requirements. When the total number of the time deviation periods of the time synchronization mode is not greater than the preset number of deviation periods, the process proceeds to step S112. S112 determines the date with the time deviation period according to the distribution data of the time deviation period on different dates in the time synchronization mode, and uses it as the time deviation date. When the number ratio of the time deviation date does not meet the requirement, proceed to step S113; when the number ratio of the time deviation date meets the requirement, proceed to step S114; S113: when the total number of the time synchronization deviation periods of the time synchronization mode is within the preset deviation period interval, it is determined that the time synchronization processing reliability of the time synchronization mode does not meet the requirement; when the total number of the time synchronization deviation periods of the time synchronization mode is not within the preset deviation period interval, the process proceeds to step S114; S114 determines the basic deviation coefficient of the time synchronization mode according to the ratio of the number of time synchronization deviations to the number of time synchronization processings on different time synchronization deviation dates and the proportion of the number of time synchronization deviation dates. When the basic deviation coefficient of the time synchronization mode does not meet the requirements, it is determined that the time synchronization processing reliability of the time synchronization mode does not meet the requirements. When the basic deviation coefficient of the time synchronization mode meets the requirements, it proceeds to step S12.

[0032] Furthermore, the basic deviation coefficient is determined according to the product of the maximum value of the ratio of the number of time synchronization deviations to the number of time synchronization processing times on different time synchronization deviation dates and the proportion of the number of time synchronization deviation dates.

[0033] Optionally, the above step S12 includes the following contents: S121 determines the number of times different time periods are identified as time deviation time periods based on the distribution data of the time deviation time periods of the time synchronization mode on different dates, and uses the number of time deviations as the number of time deviations. When there is no time period in which the number of time deviations is less than the preset number of deviations, it is determined that the time synchronization processing reliability of the time synchronization mode does not meet the requirements. When there is a time period in which the number of time deviations is not less than the preset number of deviations, the process proceeds to step S122. S122: The number of times different time periods are identified as time synchronization deviation time periods is used as the number of time synchronization deviations, and the ratio of the number of time synchronization deviations to the number of time synchronization processing in the time period is combined to determine the time synchronization deviation coefficients of the different time periods. When there is a time period in which the time synchronization deviation coefficient meets the requirements, the process proceeds to step S123. When there is no time period in which the time synchronization deviation coefficient meets the requirements, it is determined that the time synchronization processing reliability of the time synchronization mode does not meet the requirements. S123 determines the deviation coefficient threshold of the time period based on the basic deviation coefficient of the time synchronization mode. When the number of time periods in which the time synchronization deviation coefficient is greater than the deviation coefficient threshold is greater than the time period number setting value, it is determined that the time synchronization processing reliability of the time synchronization mode does not meet the requirements. When the number of time periods in which the time synchronization deviation coefficient is greater than the deviation coefficient threshold is not greater than the time period number setting value, proceed to step S13.

[0034] S3: obtaining distribution data of different time periods in which different time synchronization modes are identified as time synchronization deviation time periods, and using the distribution data identified as time synchronization deviation time periods to determine the time synchronization processing time periods and time synchronization processing priorities in the time periods, and using the time synchronization processing priorities to determine the priority time synchronization processing time periods; It should be noted that if Figure 3 As shown, the method for determining the time synchronization processing period in the period is: Determine the number of the timing deviation periods in the time period according to the distribution data of the timing deviation periods in the time period according to the different timing modes; Determine the total number of timing deviation periods based on the number of timing deviation periods in the period under different timing modes; According to the total number of time synchronization deviation periods in the period, it is determined whether the period is a time synchronization processing period.

[0035] Further, when the total number of corresponding deviation time periods in the time period is less than a preset number threshold, the time period is determined to be a time synchronization processing time period.

[0036] It should also be noted that the time synchronization processing priority of the time synchronization processing period is determined from small to large according to the total number of deviation periods corresponding to the time synchronization processing period.

[0037] Optionally, determining a priority time synchronization processing period by using the time synchronization processing priority specifically includes: The priority time synchronization processing period is a time synchronization processing period with the highest time synchronization processing priority.

[0038] Optionally, the method for determining the time synchronization processing period in the period is: Determine the number of time synchronization deviation periods in the time period according to the different time synchronization modes according to the distribution data of the time synchronization deviation periods in the time period, and when there is a time synchronization mode whose number of time synchronization deviation periods does not meet the requirements, determine that the time period does not belong to the time synchronization processing period; When there is no time synchronization mode in which the number of time synchronization deviation periods does not meet the requirements: When the number of time synchronization deviation periods in the time period of different time synchronization modes is within the preset deviation number range: it is determined that the time period does not belong to the time synchronization processing period; When the number of the time synchronization deviation periods in the time period is not within the preset deviation number range, the time synchronization mode: Determine the total number of time synchronization deviation periods based on the number of time synchronization deviation periods in the time period of different time synchronization modes, and when the total number of time synchronization deviation periods in the time period does not meet the requirement, determine that the time period does not belong to the time synchronization processing time period; When the total number of timing deviation periods in the period meets the requirement: When the total number of the time synchronization deviation periods in the time period is less than the preset number setting value, it is determined that the time period belongs to the time synchronization processing period; When the total number of the time synchronization deviation periods in the period is not less than the preset number setting value: Determine the time synchronization processing deviation coefficients of different time synchronization modes according to the number of time synchronization deviation periods in the time period of different time synchronization modes and the number of time synchronization processing times of different time synchronization modes in the time period; when there is a time synchronization mode in the time period whose time synchronization processing deviation coefficient does not meet the requirements, determine that the time period does not belong to the time synchronization processing time period; When there is no time synchronization mode in which the time synchronization processing deviation coefficient does not meet the requirements during the period: Based on the time synchronization processing deviation coefficients of different time synchronization modes in the time period, the time synchronization processing credibility coefficient of the time period is determined, and the time synchronization processing credibility coefficient is used to determine whether the time period is a time synchronization processing period.

[0039] S4 obtains the time synchronization processing results of different time synchronization modes in the priority time synchronization processing period, and determines the need for correction processing of the target device in combination with the distribution data of the time synchronization deviation periods of different time synchronization modes in the priority time synchronization processing period. Then, the adjustment processing strategy of the priority time synchronization processing period is determined according to the correction processing data in the priority time synchronization processing period and the time synchronization processing priority.

[0040] Further, such as Figure 4 As shown, it is determined that the target device needs to be corrected, specifically including: Determining trust weight coefficients of different time synchronization modes based on the proportion of the number of time synchronization deviation periods of different time synchronization modes in the priority time synchronization processing period; Based on the time synchronization processing results of different time synchronization modes in the priority time synchronization processing period, determine the deviation between the time synchronization processing results of different time synchronization modes, and use the deviation to determine the consistent time synchronization mode and the deviation time synchronization mode; The timing credibility coefficient is determined according to the difference between the sum of the credibility weight coefficients of different consistent timing modes and the credibility weight coefficient of the deviation timing mode, and the timing credibility coefficient is used to determine whether deviation correction processing of the target device is required.

[0041] It should be noted that when the time synchronization credibility coefficient is greater than the preset credibility coefficient, the time synchronization processing result of the consistent time synchronization mode is used to perform the correction processing of the target device.

[0042] In one possible embodiment, the method for determining the adjustment processing strategy of the priority time synchronization processing period is: Determine the number of deviations between the time synchronization processing results of different time synchronization modes in the priority time synchronization processing period based on the processing results of different time synchronization modes at any time in the priority time synchronization processing period, and use it as the number of data deviations; The number of time synchronization processing times in the priority time synchronization processing period is used as the matching time synchronization processing times; The proportion of the number of data deviations in the number of matching time synchronization processing times is used as a time synchronization deviation factor, and the adjustment processing strategy of the priority time synchronization processing period is determined by using the time synchronization deviation factor and the time synchronization processing priority.

[0043] Furthermore, the adjustment processing strategy of the priority time synchronization processing period is determined by using the time synchronization deviation factor and the time synchronization processing priority, specifically including: When the timing deviation factor is less than a preset deviation factor threshold, it is determined that there is no need to adjust the priority timing processing period; When the timing deviation factor is not less than the preset deviation factor threshold, the priority timing processing period is adjusted and the priority timing processing period is switched to a timing processing period with the highest timing processing priority other than the priority timing processing period.

[0044] In another possible embodiment, the method for determining the adjustment processing strategy of the priority time synchronization processing period is: Based on the processing results of different time synchronization modes at any time in the priority time synchronization processing period, it is determined that there is no deviation between the time synchronization processing results of different time synchronization modes in the priority time synchronization processing period, and it is determined that there is no need to adjust the priority time synchronization processing period; When there are deviations between the time synchronization processing results of different time synchronization modes in the priority time synchronization processing period: The number of deviations between the time synchronization processing results of different time synchronization modes is used as the number of data deviations. When the number of data deviations does not meet the requirement, it is determined to switch the priority time synchronization processing period to a time synchronization processing period with the highest time synchronization processing priority other than the priority time synchronization processing period. When the number of data deviations meets the requirements: The number of time synchronization processing times in the priority time synchronization processing period is used as the matching time synchronization processing times, and the proportion of the number of data deviation times in the matching time synchronization processing times is used as the time synchronization deviation factor. When the time synchronization deviation factor does not meet the requirements, it is determined to switch the priority time synchronization processing period to a time synchronization processing period with the highest time synchronization processing priority excluding the priority time synchronization processing period; When the timing deviation factor meets the requirements: The data deviation coefficients of different data deviation times are determined based on the deviation of the time synchronization processing results between different time synchronization modes in different data deviation times. When there is a data deviation number where the data deviation coefficient does not meet the requirements: When the number of data deviations that do not meet the requirements of the data deviation coefficient is greater than the preset deviation number threshold, it is determined to switch the priority time synchronization processing period to a time synchronization processing period with the highest time synchronization processing priority other than the priority time synchronization processing period; When there is no data deviation number that does not meet the requirements for the data deviation coefficient or the data deviation number that does not meet the requirements is not greater than the preset deviation number threshold: The time synchronization reliability coefficient of the priority time synchronization period is determined based on the product of the average value of the data deviation coefficient of different data deviation times and the time synchronization deviation factor, and the adjustment processing strategy of the priority time synchronization period is determined using the time synchronization reliability coefficient and the time synchronization priority.

[0045] Furthermore, the adjustment processing strategy of the priority time synchronization processing period is determined by using the time synchronization processing reliability coefficient and the time synchronization processing priority, which specifically includes: When the time synchronization reliability coefficient meets the requirement, it is determined that there is no need to adjust the priority time synchronization period; When the time synchronization reliability coefficient does not meet the requirement, the priority time synchronization period is adjusted and the priority time synchronization period is switched to a time synchronization period with the highest time synchronization priority except the priority time synchronization period.
