Abstract
Description
Technical Field
[0001] This invention relates to the field of navigation aids technology, and more specifically, to a method and system for disseminating navigation aid information based on AIS navigational aids. Background Technology
[0002] As a core safety facility for maritime navigation, navigation aids are crucial for ensuring safe navigation, optimizing navigation organization, and improving the overall operational efficiency of waterways through accurate and efficient dissemination of navigational information. However, with the continuous surge in global maritime traffic, the obvious trend towards larger and faster vessels, and the increasingly complex waterway environment, the traditional navigational information dissemination model, which mainly relies on manual inspections, scheduled broadcasts, and static markers, has gradually revealed many shortcomings due to the surge in maritime traffic.
[0003] Traditional methods lack a scientific hierarchical evaluation system and rely solely on experience to prioritize navigational aid data. This leads to subjective and arbitrary weighting of key indicators such as the degree of impact on navigation and data timeliness, without consistency verification, and the rationality of the weights cannot be guaranteed.
[0004] Furthermore, the lack of standardized procedures for quantitative scoring and weighted calculations leads to vague single-indicator scores and large deviations in overall scores, making it difficult to accurately select high-priority navigational aid information. At the same time, the rigid release logic of traditional systems makes it difficult to implement release strategies based on data priority, easily resulting in problems such as delayed release of critical navigational warnings and redundant push of invalid information, seriously affecting navigation safety and release efficiency.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention
[0006] To address the problems in related technologies, this invention proposes a method and system for disseminating navigational aid information based on AIS beacons, in order to overcome the aforementioned technical problems existing in the existing related technologies.
[0007] Therefore, the specific technical solution adopted by the present invention is as follows: Firstly, the present invention proposes a method for disseminating navigational aid information based on AIS navigation aids, comprising: acquiring multi-source navigation aid data using AIS navigation aid equipment, and performing aggregation and mapping processing on the multi-source navigation aid data through a data acquisition channel to obtain multi-source navigation aid status data; using a rapid filtering mechanism to filter and analyze the multi-source navigation aid status data to obtain a set of navigation aid status data to be published, and prioritizing the set of navigation aid status data to be published to obtain priority navigation aid data information; performing publication adaptation processing based on the priority navigation aid data information to obtain standardized publication data packets, and performing differential matching on the standardized publication data packets to obtain corresponding publication instructions; based on the publication instructions, using the AIS communication link to publish the standardized publication data packets to the corresponding target navigation area; constructing a publication status monitoring system, using the publication status monitoring system to dynamically monitor the execution process of the publication instructions, and optimizing the publication parameters based on the monitoring results and feedback information to obtain optimized publication control parameters, so as to achieve the autonomy, accuracy, and dynamic adaptation of the navigation aid information publication process.
[0008] Furthermore, multi-source navigation aid data is acquired using AIS navigation aid equipment, and the multi-source navigation aid data is aggregated and mapped through a data acquisition channel to obtain multi-source navigation aid status data. This includes: using the multi-source sensors on the AIS navigation aid equipment to collect navigation aid position data, navigation aid attitude data, navigation aid power supply data, and surrounding marine environment data to obtain raw multi-source navigation aid data; transmitting the raw multi-source navigation aid data collected by each sensor to the local navigation aid data aggregation node through a wired and wireless integrated data acquisition channel using a data segmentation transmission method; using the data cleaning terminal built into the data aggregation node to perform noise filtering on the raw multi-source navigation aid data transmitted to the node, removing abnormal fluctuation data and invalid or missing data; and using navigation aid data mapping rules to associate and map the cleaned raw multi-source navigation aid data with the navigation aid status data fields, completing data format unification and field matching to obtain multi-source navigation aid status data.
[0009] Furthermore, a rapid filtering mechanism is used to analyze and filter multi-source navigational aid status data to obtain a set of navigational aid status data to be published. This set of data is then prioritized to obtain priority navigational aid data information. This prioritized data includes: constructing a rapid filtering mechanism based on threshold determination, pre-setting effective threshold ranges for each type of navigational aid status data, comparing each multi-source navigational aid status data with its corresponding threshold range; filtering out navigational aid status data within the effective threshold range, and removing invalid data exceeding the threshold range to generate the set of navigational aid status data to be published; constructing a navigational aid data priority evaluation index system, selecting navigational impact, data timeliness, and safety correlation level as core evaluation indicators; assigning weights to each evaluation indicator using the analytic hierarchy process (AHP) to obtain a priority score for each data point in the set of navigational aid status data to be published; and sorting the data set from highest to lowest priority score to obtain priority navigational aid data information.
[0010] Furthermore, the Analytic Hierarchy Process (AHP) is used to assign weights to each evaluation indicator, resulting in a priority score for each data point in the set of navigational aid status data to be released. This score includes: using navigational aid data priority as the target layer, navigational impact, data timeliness, and safety correlation level as the criteria layer, and the data to be scored as the scheme layer; determining the relative importance of each indicator in the criteria layer through a comparison matrix, and calculating the initial weights of each indicator using the eigenvalue method; performing a consistency check on the initial weights, and adjusting the comparison matrix if the check fails until the weights meet the consistency requirements, thus obtaining the indicator weights; using a percentage-based scoring method, quantifying the indicators of each criteria layer for each data point to be scored, thus obtaining the single-indicator scoring result; and finally, calculating the weighted sum of the single-indicator scoring results according to the final indicator weights to obtain the comprehensive priority score for each data point.
[0011] Furthermore, the navigational aid data information based on priority undergoes release adaptation processing to obtain standardized release data packets. Differential matching is then performed on these standardized release data packets to obtain corresponding release instructions. This includes: format adaptation processing of the priority navigational aid data information to unify the data encoding format and data transmission frame structure; compression processing of the format-adapted navigational aid data information using a data compression algorithm to reduce data transmission volume and obtain standardized release data packets; constructing differential matching rules for priority levels, pre-setting the release scope, release frequency, and transmission rate parameters corresponding to each priority level; comparing and matching the priority level corresponding to the standardized release data packets with the differential matching rules, extracting the corresponding release parameters, and generating the corresponding release instructions.
[0012] Furthermore, based on the release instructions, the standardized release data packets are released to the corresponding target navigation area using the AIS communication link, including: establishing a directional communication link through the AIS communication terminal built into the navigation mark based on the release range parameters in the release instructions, and locking onto the ship's AIS receiving terminal within the target navigation area; adjusting the signal transmission power and data transmission baud rate of the AIS communication terminal according to the transmission rate parameters in the release instructions; and periodically sending the standardized release data packets to the target navigation area through the directional AIS communication link according to the release frequency requirements in the release instructions, thereby completing the directional release of the standardized release data packets.
[0013] Furthermore, a release status monitoring system is constructed to dynamically monitor the execution process of release commands. The release parameters are then optimized based on the monitoring results and feedback information to obtain optimized release control parameters. This achieves autonomous, precise, and dynamically adaptable release of navigation aid information. The system includes: constructing a release status monitoring system composed of navigation aid monitoring nodes, ship-side feedback nodes, and shore-based control nodes. Navigation aid monitoring nodes collect real-time execution status data of release commands, ship-side feedback nodes collect information reception status data, and shore-based control nodes summarize the data. Navigation aid monitoring nodes collect real-time signal transmission status, data transmission progress, and link connection status during the execution of release commands to obtain release process monitoring data. Ship AIS receiving terminals provide feedback to the navigation aid regarding successful information reception, data integrity, and reception latency. Shore-based control nodes perform fusion analysis of release process monitoring data and feedback information to determine whether the current release parameters meet the requirements for efficient release. Parameter optimization algorithms are used to adjust and calculate the release frequency and transmission rate parameters in the release commands to obtain optimized release control parameters.
[0014] Secondly, this invention also provides a navigation aid information dissemination system based on AIS navigation aids, comprising: a navigation aid data acquisition module, used to acquire multi-source navigation aid data using AIS navigation aid equipment, and to aggregate and map the multi-source navigation aid data through a data acquisition channel to obtain multi-source navigation aid status data; a data filtering and sorting module, used to filter and analyze the multi-source navigation aid status data using a fast filtering mechanism to obtain a set of navigation aid status data to be published, and to prioritize the set of navigation aid status data to be published to obtain priority navigation aid data information; and a data adaptation instruction module, used to provide navigation aid data information based on priority. The system performs information dissemination and adaptation processing to obtain standardized dissemination data packets. Differential matching of these standardized data packets yields corresponding dissemination instructions. The navigation aid information dissemination module, based on the dissemination instructions, uses the AIS communication link to disseminate the standardized dissemination data packets to the corresponding target navigation area. The dissemination monitoring and optimization module constructs a dissemination status monitoring system to dynamically monitor the execution process of dissemination instructions. It then combines the monitoring results and feedback information to optimize the dissemination parameters, resulting in optimized dissemination control parameters. This achieves autonomous, precise, and dynamically adapted navigation aid information dissemination.
[0015] Thirdly, the present invention also provides an electronic device, the electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the above-described method.
[0016] Fourthly, the present invention also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described method.
[0017] The beneficial effects of this invention are as follows: 1) This invention constructs a hierarchical evaluation system for navigational aid data priority, criterion-level indicators, and data to be scored. It combines a comparison matrix and eigenvalue method to calculate the weights of criterion-level indicators and complete consistency checks, thereby achieving a scientific and standardized evaluation of navigational aid data priority and avoiding the problem of subjective and arbitrary weight setting in traditional methods. 2) This invention achieves rapid screening by setting a preset effective threshold range for navigational aid status data. Combined with a standardized percentage-based quantitative scoring and weighted summation calculation process, it solves the shortcomings of traditional technologies, such as inaccurate screening of invalid data, large deviation in comprehensive scoring, and difficulty in accurately identifying high-priority navigational aid information. 3) This invention, through priority-based release adaptation processing, differentiated release instruction generation and targeted push mechanism, combined with release status monitoring and parameter optimization closed loop, ensures low-latency delivery of high-impact and high-timeliness navigation aid information, reduces redundant push of invalid information, and improves the accuracy and efficiency of navigation aid information release.

Detailed Implementation
[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention.
[0021] According to an embodiment of the present invention, a method and system for disseminating navigational aid information based on AIS beacons are proposed.
[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1 As shown, a method for disseminating navigational aid information based on AIS beacons according to an embodiment of the present invention includes: Step S1: Use AIS navigation aid equipment to acquire multi-source navigation aid data, and aggregate and map the multi-source navigation aid data through the data acquisition channel to obtain multi-source navigation aid status data; Step S2: Use a fast filtering mechanism to filter and analyze the multi-source navigation mark status data to obtain a set of navigation mark status data to be published, and sort the navigation mark status data set to be published by priority to obtain navigation mark data information of priority. Step S3: Based on priority, the navigation mark data information is adapted for release to obtain a standardized release data packet. The standardized release data packet is then matched for differences to obtain the corresponding release instruction. Step S4: Based on the release command, use the AIS communication link to release the standardized release data packet to the corresponding target air traffic area; Step S5: Construct a release status monitoring system. Use the release status monitoring system to dynamically monitor the execution process of release commands, and combine the monitoring results and feedback information to optimize the release parameters, so as to obtain optimized release control parameters, so as to realize the autonomy, accuracy and dynamic adaptation of the navigation aid information release process.
[0023] In this optional embodiment, multi-source navigation mark data is acquired using AIS navigation mark equipment, and the multi-source navigation mark data is aggregated and mapped through a data acquisition channel to obtain multi-source navigation mark status data. This includes: using multi-source sensors mounted on the AIS navigation mark equipment to collect navigation mark position data, navigation mark attitude data, navigation mark power supply data, and surrounding marine environment data to obtain raw multi-source navigation mark data; transmitting the raw multi-source navigation mark data collected by each sensor to the local navigation mark data aggregation node through a wired and wireless fusion data acquisition channel using a data segmentation transmission method; using the data cleaning terminal built into the data aggregation node to perform noise filtering on the raw multi-source navigation mark data transmitted to the node, removing abnormal fluctuation data and invalid or missing data; and using navigation mark data mapping rules to associate and map the cleaned raw multi-source navigation mark data with the navigation mark status data fields, completing data format unification and field matching to obtain multi-source navigation mark status data.
[0024] In this optional embodiment, a rapid filtering mechanism is used to filter and analyze multi-source navigation mark status data to obtain a set of navigation mark status data to be published. The set of navigation mark status data to be published is then prioritized to obtain priority navigation mark data information. This includes: constructing a rapid filtering mechanism based on threshold determination, pre-setting effective threshold ranges for each type of navigation mark status data, comparing each multi-source navigation mark status data with its corresponding threshold range; filtering out navigation mark status data within the effective threshold range, and removing invalid data exceeding the threshold range to generate a set of navigation mark status data to be published; constructing a navigation mark data priority evaluation index system, selecting navigation impact degree, data timeliness, and safety association level as core evaluation indicators; assigning weights to each evaluation indicator using the analytic hierarchy process (AHP) to obtain a priority score for each piece of data in the set of navigation mark status data to be published; and sorting the data set from high to low priority scores to obtain priority navigation mark data information.
[0025] Specifically, a threshold-based rapid screening mechanism is constructed, pre-setting effective threshold ranges for various types of navigation aid status data. The thresholds for navigation aid position offset are set at ±5 meters, power supply voltage at 10-14V, and ambient wind speed at 0-25m / s. Multi-source navigation aid status data are compared one by one with the corresponding threshold ranges, filtering out valid data within the thresholds and removing abnormal data exceeding the thresholds, such as invalid data with an 8-meter position offset or a 9V voltage. This generates a set of navigation aid status data to be published. Simultaneously, a navigation aid data priority evaluation index system is constructed, selecting navigation impact, data timeliness, and safety correlation level as core indicators. Using the analytic hierarchy process (AHP), weights are assigned to these three factors at 40%, 35%, and 25%, respectively. The priority score for each data point is calculated by substituting the data. For example, if a channel depth data has a navigation impact score of 90, the final priority score is 90×40%+85×35%+95×25%=89.5. The data is then sorted from highest to lowest score to obtain priority navigation aid data information, ensuring that high-impact, high-timeliness, and high-safety-correlation data are published first.
[0026] In this optional embodiment, the analytic hierarchy process (AHP) is used to assign weights to each evaluation indicator to obtain a priority score for each piece of data in the set of navigational aid status data to be released. This includes: taking the priority of navigational aid data as the target layer, the degree of navigational impact, data timeliness, and safety correlation level as the criteria layer, and the data to be scored as the scheme layer; determining the relative importance of each indicator in the criteria layer through a comparison matrix, and calculating the initial weight of each indicator using the eigenvalue method; performing a consistency check on the initial weights, and adjusting the comparison matrix if the check fails until the weights meet the consistency requirements to obtain the indicator weights; using a percentage-based scoring method, quantifying and scoring each criterion-layer indicator of each piece of data to be scored to obtain a single indicator score result; and performing a weighted summation of the single indicator scores according to the final indicator weights to obtain a comprehensive priority score for each piece of data.
[0027] Specifically, a hierarchical model was constructed, defining the target layer as the priority of navigational aid data, the criteria layer as three indicators including the degree of navigational impact, and the scheme layer as the navigational aid data to be scored. A comparison matrix for the criteria layer was constructed using importance ratios of 2:1, 3:1, and 2:1, with initial weights of 0.48, 0.32, and 0.20 obtained through the eigenvalue method. After consistency testing, CI=0.02, RI=0.58, and CR=0.03 < 0.1, and the test passed, determining the final weights. A percentage system was used to quantify and score the data. For example, if a certain channel deviation data was scored 90, 85, and 92 points respectively for the three indicators, the weighted sum would yield 88.4 points, which is the comprehensive priority score for that data.
[0028] In this optional embodiment, priority-based navigational aid data information is subjected to release adaptation processing to obtain standardized release data packets. Differential matching is then performed on these standardized release data packets to obtain corresponding release instructions. This includes: performing format adaptation processing on the priority-based navigational aid data information to unify the data encoding format and data transmission frame structure; compressing the format-adapted navigational aid data information using a data compression algorithm to reduce data transmission volume and obtain standardized release data packets; constructing differential matching rules for priority levels, pre-setting the release scope, release frequency, and transmission rate parameters corresponding to each priority level; comparing and matching the priority level corresponding to the standardized release data packets with the differential matching rules, extracting the corresponding release parameters, and generating the corresponding release instructions.
[0029] In this optional embodiment, based on the release command, the standardized release data packet is released to the corresponding target navigation area using the AIS communication link, which includes: constructing a directional communication link through the AIS communication terminal built into the navigation mark based on the release range parameters in the release command, and locking the ship AIS receiving terminal in the target navigation area; adjusting the signal transmission power and data transmission baud rate of the AIS communication terminal according to the transmission rate parameters in the release command; and periodically sending the standardized release data packet to the target navigation area through the directional AIS communication link according to the release frequency requirements in the release command, thereby completing the directional release of the standardized release data packet.
[0030] In this optional embodiment, a release status monitoring system is constructed to dynamically monitor the execution process of release commands. The release parameters are then optimized based on the monitoring results and feedback information to obtain optimized release control parameters. This achieves autonomous, precise, and dynamically adaptable release of navigation aid information. The system includes: constructing a release status monitoring system composed of navigation aid monitoring nodes, ship-side feedback nodes, and shore-based control nodes. The navigation aid monitoring nodes collect real-time execution status data of release commands, the ship-side feedback nodes collect information reception status data, and the shore-based control nodes summarize the data. The navigation aid monitoring nodes collect real-time signal transmission status, data transmission progress, and link connection status during the execution of release commands to obtain release process monitoring data. The ship's AIS receiving terminal provides feedback to the navigation aid regarding successful information reception, data integrity, and reception latency. The shore-based control nodes perform fusion analysis of the release process monitoring data and feedback information to determine whether the current release parameters meet the requirements for efficient release. Finally, a parameter optimization algorithm is used to adjust and calculate the release frequency and transmission rate parameters in the release commands to obtain optimized release control parameters.
[0031] Specifically, parameter optimization algorithms are used to adjust parameters such as release frequency and transmission rate, for example, from 3 times per minute to 5 times per minute.

The data filtering and sorting module 2 is used to filter and analyze multi-source navigation mark status data using a fast filtering mechanism to obtain a set of navigation mark status data to be published, and to sort the set of navigation mark status data to be published by priority to obtain navigation mark data information of priority. The data adaptation instruction module 3 is used to perform release adaptation processing on priority-based navigation mark data information to obtain standardized release data packets, and to perform differential matching on the standardized release data packets to obtain corresponding release instructions; The navigation mark information publishing module 4 is used to publish standardized publishing data packets to the corresponding target navigation area based on the publishing command and using the AIS communication link; The release monitoring and optimization module 5 is used to build a release status monitoring system. The release status monitoring system is used to dynamically monitor the execution process of release commands, and the release parameters are optimized by combining the monitoring results and feedback information to obtain optimized release control parameters, so as to realize the autonomy, accuracy and dynamic adaptation of the navigation aid information release process.
