It should be understood that the present application is not limited by the example embodiments described herein. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application. Additionally, it should be noted that for the sake of description, only the parts related to the present application are shown in the drawings rather than all of them.
[0018] Embodiment 1. Please refer to the attached Figure 1 , the present application provides a multi-point synchronous processing method for shipborne navigation data, which is applied to a multi-point synchronous processing device for shipborne navigation data, and specifically includes: obtaining the state data of shipborne navigation, where the state data includes an instantaneous state set, and the instantaneous state set corresponds to the state instantaneous set.
[0019] Specifically, various types of data of the ship are collected in real time through different sensors and devices as state data to reflect the current operating condition of the ship. For example, the position information obtained through GPS describes the longitude and latitude of the ship, and the speed and heading reflect the instantaneous motion state of the ship. The instantaneous state set refers to the set of ship operation data recorded by the corresponding sensors at a specific time point, including position, speed, heading, acceleration, engine state, etc., which can present the real-time state of the ship. The state instantaneous set is the corresponding time point of the data collection set obtained by the sensor.
[0020] Append data to adjacent state instants in the state instantaneous set to obtain an appended instantaneous state set and an appended state instantaneous set.
[0021] Specifically, by performing additional collection at the interval time points between the collection time points, more real-time information can be obtained. The append not only makes the instantaneous state set more complete, but also improves the continuity and real-time nature of the data, and can more accurately reflect the state change of the ship between two time points. For example, the original collection period is once every minute. By appending collection time points between the collection time points, the modified collection period is once every thirty seconds. The appended collection time points are used as the appended state instantaneous set, and the collection data of the appended state instantaneous set is used as the appended instantaneous state set.
[0022] Combine the data according to the appended instantaneous state set and the instantaneous state set to obtain an enhanced instantaneous state set.
[0023] Specifically, the additional instantaneous state set is combined with the instantaneous state set. After the new collected data is combined with the original collected data, all the collected data is more compact in time and can more accurately reflect the state change of the ship between two time points. That is, the enhanced instantaneous state set formed by combining the additional data with the original instantaneous state set is more complete and continuous than the original data set, and can capture the change of the ship's operating state more precisely through more frequent sampling.
[0024] Synchronization authentication is performed on the enhanced instantaneous state set according to the collection source to obtain a synchronization coefficient.
[0025] Specifically, performing synchronization authentication on the enhanced instantaneous state set according to the collection source means comparing the data from different sources collected by different sensors or devices at the same time point to evaluate whether the data from different sources is consistent in time. If the degree of consistency of the data from different sources at this time point is higher, the value of the synchronization coefficient at this time point is larger, and vice versa. The time alignment between data sources can more accurately reflect the real-time state change of the ship and improve the credibility and accuracy of analysis.
[0026] The collection quality of the state data is evaluated according to the synchronization coefficient, and the enhanced instantaneous state set is fused according to the collection quality evaluation result to obtain a fused instantaneous state set.
[0027] Specifically, the collection quality of the ship's state data is evaluated based on the synchronization coefficient to judge the reliability and accuracy of the data. When the synchronization coefficient is higher, it indicates that the collection quality of the data from different sources is better, and vice versa, it indicates that there may be collection deviations in the sensors or devices of the data, and the collection quality is worse, and further processing is required. Align the data from multiple sensors according to the time point, and combine the synchronization coefficients corresponding to different data sources, and select the data from the collection sources with higher quality for merging. The state data of the ship becomes more complete and accurate, and can better reflect the actual operating state of the ship.
[0028] The method for multi-point synchronization processing of shipborne navigation data is applied to a device for multi-point synchronization processing of shipborne navigation data, which can achieve the technical goal of efficient synchronization and precise fusion of ship state data, and achieve the technical effects of improving the accuracy, real-time performance and reliability of ship state analysis, so as to better ensure navigation safety and improve the efficiency of ship management.
[0029] Further, this application also includes: performing time addition for adjacent state instants of the first state instant set of the first acquisition source to obtain a first additional state instant set, where the first acquisition source is extracted according to the acquisition source, and the first state instant set is extracted according to the state instant set; performing data supplementation on the first instant state set according to the first additional state instant set to obtain a first additional instant state set, where the first instant state set is extracted according to the instant state set and corresponds to the first state instant set; performing data addition on the instant state set based on the first additional instant state set to obtain the additional instant state set, and the additional instant state set corresponds to the additional state instant set.
[0030] Specifically, time addition is performed for adjacent state instants through the first state instant set of the first acquisition source to obtain a first additional state instant set. Among them, the addition is achieved by inserting a new acquisition data time point between two adjacent acquisition time points, thereby shortening the time interval of the data and further enhancing the continuity and real-time nature of the data. The first acquisition source refers to any acquisition source randomly extracted from multiple acquisition sources. The acquisition time points of the first acquisition source are used as the first state instant set.
[0031] Next, data supplementation is performed on the first instant state set according to the first additional state instant set to fill the gaps between the acquisition time points, obtaining a first additional instant state set, thereby making the time distribution of the data more compact, and the original state set is expanded and improved, which helps to more accurately reflect the state change of the ship between two time points.
[0032] Data addition is performed on the instant state set based on the first additional instant state set, and the state data originally collected at intervals is further refined to obtain an additional instant state set, where the additional instant state set corresponds to the first additional state instant set. Through the data addition process, the sampling frequency increases, thereby improving the timeliness and continuity of the data, making the change of the ship state presented more smoothly, and further providing a more accurate basis for subsequent analysis.
[0033] Further, this application also includes: extracting a first instant and a second instant from the first state instant set, where the first instant and the second instant are adjacent state instants; performing time addition on the first instant and the second instant to obtain a first additional instant, where the distance from the first additional instant to the first instant is the same as the distance to the second instant; performing data supplementation of the first additional instant on the first instant state set based on the additional state model to obtain a first additional instant state; performing data supplementation on the first instant state set based on the first additional instant state to obtain the first additional instant state set.
[0034] Specifically, two pieces of state data at adjacent time points are instantaneously extracted from the first state. The first instant and the second instant respectively represent different time points of the ship. The process of time addition is to insert new acquisition time points between these two adjacent instants, so as to make the time interval of the data more dense. The added time points maintain the same distance as that between the first instant and the second instant to ensure the symmetry of the newly added data points in time, so as to more accurately describe the change of the ship's state. The added state model is obtained by mathematically modeling the existing state data set, calculating the data of the first added instant state, and then being able to fill in the blanks in the original data, making the operation state of the ship smoother and more continuous in the time dimension, and further improving the timeliness and reliability of the data.
[0035] Based on the first added instant state, data supplementary acquisition is carried out on the acquisition data of any two adjacent original acquisition times in the first instant state set to obtain the first added instant state set, forming a more complete and continuous state data set. Furthermore, the description of the ship's state becomes more accurate, and the dynamic changes of the ship at each time point can be reflected more accurately.
[0036] Furthermore, this application also includes: training an added generation channel based on adjacent instant samples and adjacent state samples in the first state sample set as generation samples, training an added discrimination channel based on added instant samples and added state samples as discrimination samples, and obtaining the added state model by fusing the added generation channel and the added discrimination channel; inputting the first instant and the second instant into the added state model for added generation to obtain the first added instant state, where the first added instant state corresponds to the first added instant.
[0037] Specifically, adjacent instant samples and adjacent state samples are extracted from the first state sample set at the historical time corresponding to the first acquisition source to generate training samples. The adjacent instant samples are any two adjacent time points among the acquisition data time points of the ship's state, and the state samples are the state data acquired at these adjacent time points, and are then used to train the added generation channel.
[0038] Then, an added discrimination channel is trained based on added instant samples and added state samples as discrimination samples, so as to provide support for judging whether the generated data is reliable and whether it conforms to the actual operation condition. The purpose of the discrimination channel is to judge whether the generated data meets the expectations, ensure that the generated instant state data has a high credibility, and can accurately reflect the real operation state of the ship. Then, the added state model is obtained by fusing the added generation channel and the added discrimination channel, so as to improve the quality and accuracy of the data in multiple dimensions and ensure the timeliness and continuity of the ship's state data.
[0039] Finally, append the first instantaneous and second instantaneous input to the append state model for append generation to obtain the first appended instantaneous state. Here, the first appended instantaneous state corresponds to the first appended instant. After inputting the original first instantaneous and second instantaneous data into the append state model, new appended instantaneous state data is output, thus making the description of the ship's state more continuous and refined.
[0040] The data generated by the append state model can fill the gaps between the acquisition time points, shorten the data period, and thus improve the timeliness and accuracy of the data.
[0041] Furthermore, this application also includes: obtaining the instantaneous sample step and state sample step of the first acquisition source; performing time series training according to the instantaneous sample step and state sample step to generate a full sequence state; extracting adjacent instantaneous samples, adjacent state samples, appended instantaneous samples, and appended state samples from the full sequence state, where the distances between the appended instantaneous samples and the adjacent instantaneous samples are the same.
[0042] Specifically, obtain the instantaneous sample step and state sample step of the first acquisition source. The instantaneous sample step represents multiple instantaneous samples in the time series, and the state sample step is the acquisition data corresponding to the instantaneous sample step.
[0043] Next, perform time series training according to the instantaneous sample step and state sample step to generate a full sequence state. Organize the ship state data into a complete time series in chronological order according to the time interval, so as to comprehensively reflect the operating state of the ship, and then form an ordered and continuous state sequence, providing a structured data basis for subsequent analysis.
[0044] Then, extract adjacent instantaneous samples, adjacent state samples, appended instantaneous samples, and appended state samples from the full sequence state. Among them, the distances between the appended instantaneous samples and two time points in the adjacent instantaneous samples are the same, filling the blanks in the time interval, making the time distribution of the ship state data denser, and ensuring the consistency and coherence of the data time interval.
[0045] By extracting adjacent samples from the full sequence state and generating appended samples, the data set is further improved, effectively increasing the continuity and timeliness of the data, and enabling the changes in the ship's state to be captured more meticulously and accurately.
[0046] Furthermore, this application also includes: performing state synchronization authentication according to the first enhanced instantaneous state set of the first acquisition source and the traversal enhanced instantaneous state set of the traversed acquisition source to obtain the first synchronization coefficient, where the first acquisition source is extracted according to the acquisition source; traversing the acquisition source to perform traversal authentication on the enhanced instantaneous state set to obtain the synchronization coefficient.
[0047] Specifically, the enhanced instantaneous state set obtained from the first acquisition source is synchronously authenticated with all the enhanced instantaneous state sets obtained by sequentially accessing the acquisition sources. By comparing the corresponding situations of the data sets at the same time point, the synchrony between the data of each acquisition source is evaluated to ensure the temporal consistency of each data source, thereby improving the accuracy and reliability of the overall data. The enhanced instantaneous state set of the first acquisition source is based on the acquisition sources randomly extracted from multiple sensors or devices.
[0048] Next, by traversing different acquisition sources, the synchrony authentication of each enhanced instantaneous state set is performed to obtain the synchrony coefficient of each acquisition source with other acquisition sources, which reflects the degree of temporal alignment between multiple data sources. The higher the value of the synchrony coefficient, the higher the degree of consistency of the data from each source at the same time, and vice versa, indicating the existence of an acquisition source with acquisition data deviation.
[0049] By obtaining the synchrony coefficient, the temporal consistency and quality of the data set can be effectively evaluated and improved.
[0050] Furthermore, the present application further includes: comparing the synchrony coefficient based on a synchrony coefficient threshold to extract collaborative acquisition sources; fusing according to the collaborative instantaneous state set of the collaborative acquisition sources to obtain the fused instantaneous state set, wherein the collaborative instantaneous state set is extracted according to the enhanced instantaneous state set.
[0051] Specifically, the synchrony coefficients of each acquisition source are compared based on the synchrony coefficient threshold, and the acquisition sources with higher synchrony coefficients are selected to extract the collaborative acquisition sources that meet the synchrony coefficient threshold for collaborative work. The synchrony coefficient threshold is obtained by those skilled in the art according to the actual situation.
[0052] Next, the collaborative instantaneous state set is extracted according to the enhanced instantaneous state set. Based on the selected collaborative acquisition sources, the collaborative instantaneous state set is extracted, thereby ensuring the consistency and reliability of the data. By fusing the collaborative instantaneous state sets, the fused instantaneous state set is obtained. By integrating the data of multiple collaborative acquisition sources, the integrity, accuracy, and timeliness of the data are improved, so as to more comprehensively reflect the operating state of the ship.
[0053] In summary, the multi-point synchronous processing method for shipborne navigation data provided by this application has the following technical effects: By obtaining the status data of shipborne navigation, the status data includes an instantaneous status set, and the instantaneous status set corresponds to the status instantaneous set; data is appended to adjacent status instants in the status instantaneous set to obtain an appended instantaneous status set and an appended status instantaneous set; data combination is performed according to the appended instantaneous status set and the instantaneous status set to obtain an enhanced instantaneous status set; synchronous authentication is performed on the enhanced instantaneous status set according to the acquisition source to obtain a synchronous coefficient; the acquisition quality of the status data is evaluated according to the synchronous coefficient, and the enhanced instantaneous status set is fused according to the acquisition quality evaluation result to obtain a fused instantaneous status set. That is to say, by achieving the technical goal of efficient synchronization and precise fusion of ship status data, the accuracy, real-time performance, and reliability of ship status analysis are improved, thereby better ensuring navigation safety and enhancing the efficiency of ship management.
