Fig. 1 shows a flowchart of a data synchronization method for an airborne radar signal of an unmanned aerial vehicle, which is provided by the embodiment of the present application, where the data synchronization method for an airborne radar signal of an unmanned aerial vehicle may be performed by a data synchronization device for an airborne radar signal of an unmanned aerial vehicle, and the data synchronization device for an airborne radar signal of an unmanned aerial vehicle may be implemented by means of hardware and/or software and is integrated in a data synchronization device (e.g. a server) for an airborne radar signal of an unmanned aerial vehicle.

The following description will be made taking, as an example, a method of performing data synchronization of an unmanned aerial vehicle-mounted radar signal to a data synchronization device of the unmanned aerial vehicle-mounted radar signal. Referring to fig. 1, the data synchronization method of the airborne radar signal to the unmanned aerial vehicle includes:

S110: and obtaining one or more flight tasks and the number of the repetition of the flight task logs corresponding to each flight task through the flight record of the unmanned aerial vehicle.

S120: and obtaining one or more airborne radar communication signals and the number of the airborne radar communication signal log repetition corresponding to each airborne radar communication signal through the airborne radar communication record.

In one embodiment, the data synchronization device for the airborne radar signal of the unmanned aerial vehicle provided by the scheme can collect the unmanned aerial vehicle behavior data of each unmanned aerial vehicle according to a set time interval (such as one day, three days, one week and the like), and execute the data synchronization method for the airborne radar signal of the unmanned aerial vehicle based on the collected unmanned aerial vehicle behavior data so as to synchronize the navigation data corresponding to each unmanned aerial vehicle.

The unmanned aerial vehicle behavior data that this scheme provided includes unmanned aerial vehicle flight record and airborne radar communication record, and unmanned aerial vehicle flight record can reflect unmanned aerial vehicle's text data that flies when platform or application carry out the interactive operation, and airborne radar communication record can reflect unmanned aerial vehicle's condition that uses airborne radar. Optionally, the client installed on the unmanned aerial vehicle device generates a corresponding unmanned aerial vehicle flight record or airborne radar communication record when the unmanned aerial vehicle performs interactive operation on a platform or an application each time or performs interactive operation on an airborne radar, and uploads the corresponding unmanned aerial vehicle flight record or airborne radar communication record to a set position (a data synchronization device or a set database of airborne radar signals of the unmanned aerial vehicle) in real time or at intervals, or performs interactive operation on the platform or the application each time for the unmanned aerial vehicle to the data synchronization device of the airborne radar signals of the unmanned aerial vehicle, or generates a corresponding unmanned aerial vehicle flight record or airborne radar communication record for the interactive operation of the airborne radar. Optionally, the flight task and the airborne radar communication signal provided by the scheme can be represented by a task code.

For example, for synchronization of navigation data of one unmanned aerial vehicle, a flight record of the unmanned aerial vehicle corresponding to a set time length (for example, 30-60 days) is obtained, one or more flight tasks corresponding to the unmanned aerial vehicle are obtained through the flight record of the unmanned aerial vehicle, and the number of repeated flight task logs corresponding to the one or more flight tasks is obtained. The number of the log repetition of the flight task is understood to be the number of the log repetition of the corresponding flight task. Optionally, the obtaining of the flight tasks may be task identification of an unmanned aerial vehicle flight record, and the number of flight task log repetition bars corresponding to each flight task may be the number of log repetition bars corresponding to the flight tasks identified by the unmanned aerial vehicle flight record, for example, when one unmanned aerial vehicle flight record detects one flight task, the number of flight task log repetition bars corresponding to the flight tasks is increased by one.

Optionally, after obtaining one or more flight tasks and the number of flight task log repetition numbers corresponding to each flight task, screening out the flight tasks with the number of flight task log repetition numbers set in front (for example, front 20), retaining a plurality of flight tasks which are most affected by the unmanned aerial vehicle behaviors, and improving the accuracy of data synchronization of the airborne radar signals to the unmanned aerial vehicle.

In one embodiment, an airborne radar communication record corresponding to a set time period (for example, 30-60 days) is obtained, one or more airborne radar communication signals corresponding to the unmanned aerial vehicle are obtained through the airborne radar communication record, and the log repetition number of the airborne radar communication signals corresponding to the one or more airborne radar communication signals is obtained. The number of log repetition of the airborne radar communication signals is understood to be the number of log repetition of the corresponding airborne radar communication signals. Alternatively, the obtaining of the airborne radar communication signals may be obtained by using tasks corresponding to the airborne radar by the unmanned aerial vehicle within a set time range (for example, 1-3 days), and the number of log repetition of the airborne radar communication signals of each airborne radar communication signal may be the number of log repetition or the number of days that the airborne radar communication signals appear within the set time length.

For example, the airborne radar communication signals used when the airborne radar is used in the set time range are collected, and the corresponding airborne radar communication record in the set time range records the airborne radar communication signals. When one or more airborne radar communication signals and the number of the log repetition of the airborne radar communication signals corresponding to the airborne radar communication signals are obtained through the airborne radar communication records, obtaining the airborne radar communication signals appearing in the airborne radar communication records within a set time length, and obtaining the number of the log repetition of the airborne radar communication signals as the number of the log repetition of the corresponding airborne radar communication signals. For example, the airborne radar communication records are recorded according to the sky, the airborne radar communication signals used in the day are recorded in the daily airborne radar communication records, the airborne radar communication records corresponding to the unmanned aerial vehicle within 30 days are obtained, the airborne radar communication signals appearing in the airborne radar communication records are obtained, and the log repetition number of each airborne radar communication signal appears is used as the corresponding airborne radar communication signal log repetition number.

Optionally, after obtaining one or more airborne radar communication signals and the number of the airborne radar communication signal log repetition numbers corresponding to each airborne radar communication signal through the airborne radar communication record, a set number (for example, two) of airborne radar communication signals with the highest number of the airborne radar communication signal log repetition numbers can be reserved, a plurality of airborne radar communication signals with the greatest influence by unmanned aerial vehicle behaviors are reserved, and data synchronization accuracy of the airborne radar signals to the unmanned aerial vehicle is improved.

S130: and obtaining candidate tasks and candidate task evaluation values corresponding to the candidate tasks according to the flight tasks, the number of repetition of the flight task logs, the airborne radar communication signals and the number of repetition of the airborne radar communication signal logs.

Exemplary, after the number of flight tasks and corresponding flight task log repetition numbers and the number of airborne radar communication signals and corresponding airborne radar communication signal log repetition numbers are obtained, candidate tasks and candidate task evaluation values corresponding to the candidate tasks are obtained through the number of flight tasks, the number of flight task log repetition numbers, the number of airborne radar communication signals and the number of airborne radar communication signal log repetition numbers.

The candidate task provided by the scheme can be understood as a candidate task which can be used for synchronizing the navigation data corresponding to the unmanned aerial vehicle at present. Alternatively, candidate tasks may be obtained from the airborne radar communication signals and the flight tasks by corresponding conditions of the airborne radar communication signals and the flight tasks (i.e., whether the flight tasks have airborne radar communication signals in the flight tasks), and/or the number of repetition of the flight task logs and the number of repetition of the airborne radar communication signal logs, and the corresponding task evaluation values may be obtained as candidate task evaluation values. For example, among the airborne radar communication signals corresponding to the mission, the airborne radar communication signal having the largest number of the repetition of the airborne radar communication signal log is used as a candidate mission, or the airborne radar communication signal or the mission having the largest number of the repetition of the mission log among the number of the repetition of the airborne radar communication signal log and the number of the repetition of the mission log is used as a candidate mission.

S140: and synchronizing the navigation data through the candidate tasks and the candidate task evaluation values.

Illustratively, the navigation data is synchronized through the candidate task, the candidate task evaluation value, the navigation data and the navigation data evaluation value corresponding to the navigation data obtained above. Alternatively, the synchronization of the evaluation values of the navigation data may be to supplement new navigation data, or may be to correct the navigation data with the minimum evaluation value of the original navigation data.

In one embodiment, after obtaining the candidate task, if the candidate task does not currently have corresponding navigation data, the candidate task is directly obtained as the navigation data. Alternatively, when the number of navigation data does not reach the set number of tasks (for example, two), the candidate task may be directly added as new navigation data, or when the current navigation data evaluation value reaches the set evaluation value threshold, the navigation data is only an invalid task and the candidate task evaluation value reaches the set evaluation value threshold, the candidate task is added as new navigation data, or when the current navigation data evaluation value is smaller than the set evaluation value threshold, the candidate task is added as new navigation data. When the number of the navigation data reaches the set task number, whether to correct the navigation data with the lowest evaluation value of the candidate task is obtained through the navigation data with the lowest evaluation value of the navigation data and the candidate task evaluation value, for example, the navigation data with the lowest evaluation value of the candidate task is smaller than the first set evaluation value threshold value, or the navigation data with the lowest evaluation value of the candidate task is used when the evaluation value of the candidate task is larger than the minimum evaluation value of the navigation data and larger than the second set evaluation value threshold value (larger than the first evaluation value threshold value).

The method comprises the steps of obtaining the number of the flight task log repetition bars corresponding to one or more flight tasks and each flight task through unmanned aerial vehicle flight records, obtaining the number of the airborne radar communication signal log repetition bars corresponding to one or more airborne radar communication signals and each airborne radar communication signal through airborne radar communication records, obtaining candidate tasks and candidate task evaluation values corresponding to the candidate tasks through the number of the flight tasks, the number of the flight task log repetition bars, the number of the airborne radar communication signals and the number of the airborne radar communication signal log repetition bars, synchronizing navigation data through the candidate tasks and the candidate task evaluation values, obtaining the candidate tasks and the corresponding candidate task evaluation values through unmanned aerial vehicle flight records and the airborne radar communication records reflecting unmanned aerial vehicle behaviors, dynamically correcting the navigation data, and realizing flexible synchronization of the navigation data.

In one embodiment, the unmanned aerial vehicle flight records provided by the present scheme include a combination of one or more of flight formation data, flight environment data, flight risk data, flight path adjustment data, and flight accident data.

In one embodiment, after the unmanned aerial vehicle flight records within the set time length are obtained, unmanned aerial vehicle flight records with text related contents can be screened first, and then the unmanned aerial vehicle flight records with text related contents are segmented to obtain unmanned aerial vehicle flight record keywords.

For example, when the airborne radar communication signal with the largest number of the airborne radar communication signal log repetition stripes is a valid task and corresponds to a flight task, the airborne radar communication signal with the largest number of the airborne radar communication signal log repetition stripes is used as an alternative task, and the alternative task evaluation value is the sum of the corresponding airborne radar communication signal log repetition stripes and the flight task log repetition stripes; when the airborne radar communication signal with the largest number of the airborne radar communication signal log repetition is an effective task and does not correspond to the flight task, taking the flight task with the largest number of the flight task log repetition as an alternative task, and taking the alternative task evaluation value as the corresponding number of the flight task log repetition. When the airborne radar communication signal with the largest number of airborne radar communication signal log repetition stripes is an invalid task and the airborne radar communication signal with the largest number of airborne radar communication signal log repetition stripes is an valid task, if the airborne radar communication signal with the largest number of airborne radar communication signal log repetition stripes corresponds to a flight task, taking the airborne radar communication signal with the largest number of airborne radar communication signal log repetition stripes as an alternative task, and taking the alternative task evaluation value as the sum of the corresponding airborne radar communication signal log repetition stripes and the flight task log repetition stripes, and if the airborne radar communication signal with the largest number of airborne radar communication signal log repetition stripes does not correspond to the flight task, taking the airborne radar communication signal with the largest number of airborne radar communication signal log repetition stripes as the alternative task, and taking the alternative task evaluation value as the corresponding airborne radar communication signal log repetition stripes.
