(3) User data are acquired from an operator base station, and are synchronized to a system in a database synchronization mode through safety boundary ferry, wherein the user data comprise an equipment identification code IMEI of a mobile terminal carried by a user and longitude and latitude data of the IMEI. It can be understood that the system will perform corresponding data cleaning on the accessed data and complement the missing data information.

In this embodiment, the longitude and latitude point data of each ship at different times within the preset channel basin range is screened out from the accessed AIS data, and then the grid codes of the longitude and latitude point data of each ship are respectively calculated to obtain the second grid data of each ship. In the present embodiment, the second mesh data covers both the time dimension and the space dimension. Wherein the length of the grid may be a six-level grid.

Further, the AIS data records a ship ID of each ship, the ship ID being a unique identification code of the ship, and information for identifying the ship is available by the ship ID. Therefore, when historical grid data of a certain ship needs to be inquired, inquiry can be carried out by inputting the ship ID into the system.

And 106, matching the first grid data in the second grid data of all ships, and determining ship data in the water area data corresponding to the target user.

In this embodiment, the first grid data of each target user and the second grid data of all ships are subjected to grid collision, and according to a collision result, ship data in the water area data corresponding to the target user is determined.

Specifically, the number of the same grids between the first grid data and the second grid data is determined according to a collision result, ship data corresponding to a target user is screened out from all ship data in the water area data based on the size quantity relation of the number of the same grids, then, the track similarity of the target user and each ship in the ship data is calculated, the target ship to which the target user belongs is determined according to the track similarity and a preset similarity threshold value, and personnel on the ship are accurately determined, so that the management of the ship and the personnel on the ship is realized, the processing precision and the processing efficiency of the water area data are improved, and the management requirement on the water area data is met.

Example two:

referring to fig. 2, fig. 2 is a water area data processing method according to a second embodiment of the present invention, including:

step 201, in the operator data, a first identification code of a target user and a first longitude and latitude data set with a time sequence are obtained.

It should be noted that, in the case that step 210 is consistent with step 101, step 201 includes the following sub-steps:

s21: and screening target operator data in a preset channel basin range from the operator data.

It should be noted that, in this embodiment, because the operator data accessed in the system may be data of one city or data of a certain area in the city, the data is relatively complicated and the data size is relatively large, and in order to reduce consumption of analysis resources, this step is to screen out target operator data within a preset channel basin range from the accessed operator data.

Specifically, because the drive test data can have relevance with the base station data, the target operator data in the preset channel basin range can be screened out from the operator data by adopting the drive test data acquired by the drive test equipment near the preset channel basin, so that the operator data are preliminarily filtered, the waste of computing resources is reduced, and the processing efficiency of the water area data is further improved.

S22: and acquiring the equipment identification code and longitude and latitude data of the mobile terminal carried by each user in a preset time period from the target operator data.

In this embodiment, the equipment identification code IMEI of the mobile terminal carried by each user and the longitude and latitude data of the equipment identification code IMEI are acquired, where the preset time period may be determined according to actual conditions, and in this embodiment, the preset time period is one day.

S23: and judging whether the proportion of the number of the longitude and latitude points falling into the range of the preset channel basin to the total number of the longitude and latitude points meets the preset proportion requirement or not in the longitude and latitude point data, and if so, identifying the user corresponding to the equipment identification code as the target user.

It should be noted that in reality there is a special case: the IMEI is a device identification code which is used for identifying the IMEI in the water area, and the IMEI is a device identification code which is used for identifying the IMEI in the water area, wherein the IMEI is a device identification code which is used for identifying the IMEI in the water area, and the IMEI is a device identification code which is used for identifying the IMEI in the water area.

In order to avoid the error problem caused by the special condition, in the longitude and latitude point data of each user collected in one day, screening the users by judging whether the proportion of the number of the longitude and latitude points falling into the range of the preset channel basin to the total number of the longitude and latitude points meets the preset proportion requirement, and when the proportion of the number of the longitude and latitude points falling into the range of the preset channel basin to the total number of the longitude and latitude points does not meet the preset proportion requirement, showing that most of the longitude and latitude point data of the user are not in the range of the preset channel basin, namely, the special condition occurs.

It should be noted that, the applicant summarizes through actual data sampling and experiments that when the preset time period is one day, the preset proportion requirement is 70%, and the obtained data accuracy of the target user is higher, that is, the error of the water area data is smaller, so that the precision of water area data processing is greatly improved.

S24: the method comprises the steps of obtaining a first identification code of a target user and a first longitude point data set with a time sequence.

It should be noted that step 101 may be referred to as S24, and details are not repeated here.

Step 202, in the information acquisition device, a second identification code of the target user and a second longitude and latitude point data set with a time sequence are obtained.

It should be noted that step 202 may refer to step 102, and is not described herein again.

And 203, based on the association relationship between the first identification code and the second identification code, correcting the first longitude and latitude point data set by using the second longitude and latitude point data set to obtain a fourth longitude and latitude point data set.

It should be noted that the association relationship between the first identification code and the second identification code may be calculated and analyzed in advance, the association relationship is stored in the database, and the association relationship is called from the database when in use, so that the first identification code may be determined based on the second identification code data of the target user, and the first longitude and latitude point data set of the first identification code is corrected based on the second longitude and latitude point data set of the second identification code, so as to obtain the fourth longitude and latitude point data set.

And 204, performing outlier rejection operation on the fourth longitude and latitude point data set according to the running speed and the running distance of the ship to obtain a fifth longitude and latitude point data set.

In this embodiment, data cleaning needs to be performed on the fourth longitude and latitude point data set obtained after the correction operation is completed, and abnormal data is eliminated, so that a more accurate fifth longitude and latitude point data set is obtained. And eliminating longitude and latitude points which do not meet the requirements of the running speed and the running distance in the fifth longitude and latitude point data set by combining the running speed and the running distance of the ship.

It can be understood that the moving speed and the moving distance of the target user can be calculated according to the longitude and latitude point data at different moments, if the target user is located on a ship, the moving speed and the moving distance should meet the requirement of the running speed and the running distance of the ship, and based on the requirement, abnormal data in the second longitude and latitude point data set can be cleared, so that the accuracy of the track of the target user is further improved.

The driving speed requirement and the driving distance requirement of the ship can be obtained by sampling and calculating based on AIS data of the ship. Speed threshold range of travel speed requirement: 20-35km/h, threshold range required by driving distance: greater than or equal to 10 km.

And when the moving speed of the longitude and latitude point of the target user is calculated to be less than 20km/h or more than 35km/h, the longitude and latitude point is indicated as an outlier. And when the moving distance of the longitude and latitude point of the target user is calculated to be less than 10km, the longitude and latitude point is indicated as an outlier. More accurate longitude and latitude point data are obtained by eliminating longitude and latitude points which do not accord with the requirements of the running speed and the running distance.

And step 205, performing point supplementing operation on the missing longitude and latitude points in the fifth longitude and latitude point data set according to the running time and the running distance of the ship to obtain a third longitude and latitude point data set.

In this embodiment, a point supplementing operation is performed on the missing longitude and latitude points in the fifth longitude and latitude point data set according to the travel time and the travel distance of the ship to obtain a third longitude and latitude point data set, so that the reliability of the longitude and latitude point data of the target user is further improved.

In this embodiment, after the correction operation, the outlier rejection operation, and the point-supplementing operation are performed, the reliability of the longitude and latitude point data of the target user is greatly improved, so that the accuracy of determining the ship data corresponding to the target user is further improved, and the accuracy of processing the water area data is improved.

And step 206, carrying out grid coding calculation on the third longitude and latitude point data set to obtain first grid data.

Step 104 can be referred to in this step, and is not described herein again.

Step 207, acquiring second grid data of each ship within the preset channel basin range.

It should be noted that, the step 105 may be referred to in this step, and details are not repeated here.

And step 208, matching the first grid data in the second grid data of all ships, and determining ship data in the water area data corresponding to the target user.

It should be noted that step 208 includes the following sub-steps:

s31: and respectively carrying out grid collision operation on the first grid data of each target user and the second grid data of all ships, and determining the ships with the same grid tendency as the target users.

In this embodiment, after the grid collision operation is performed, the number of the first grid data and the second grid data having the same grid is determined, that is, the number of the target users and the number of the ships having the same grid can be determined, all the ships are sorted according to the descending order based on the number of the same grid, then the ships with the preset number are selected as the inclined ships, and the inclined ships are respectively associated with the target users. The preset number can be determined according to actual needs, and in this embodiment, the preset number is the first 10, for example, the target user a associates the inclined ship 1, the inclined ship 2, … …, and the inclined ship 10. The target user A is associated with the inclined ship 1 as a relation pair a, the target user A is associated with the inclined ship 1 as a relation pair b, and so on.

S32: and calculating the track similarity of the target user and each inclined ship.

In this embodiment, the track relationship between the target user and each inclined ship is calculated, and referring to the foregoing example, the track similarity between the relationship pair a, the track similarity between the relationship pair b, and the like are calculated.

S33: and comparing the track similarity with a preset similarity threshold, and determining ship data in the water area data corresponding to the target user according to the comparison result.

In this embodiment, the track similarity and a preset similarity threshold are obtained through comparison and calculation, if the track similarity is greater than or equal to the preset similarity threshold, the relationship pair is retained, then the track similarities of each group of relationship pairs are compared, and the inclined ship in the relationship pair with the highest similarity is selected as the target ship to which the target user belongs, that is, the ship data corresponding to the target user is determined. Referring to the example of the previous step, if the track similarity of the relationship pair a and the track similarity of the relationship pair b are both greater than the preset similarity threshold, the relationship pair a and the relationship pair b are retained, then the track similarity between the relationship pair a and the relationship pair b is compared, and if the track similarity of the relationship pair a is greater than the relationship pair b, the target ship is an inclined ship 1, that is, the ship on which the target user a sits is a ship 1, and the target user a is a ship-associated person of the ship 1.

The water area data processing method provided by the embodiment of the invention further comprises the following steps:

step 209, associating the second identification code of the target user, the information acquisition equipment and the acquisition time to obtain an association relationship pair; the information acquisition equipment is used for acquiring the second identification code.

It should be noted that, in this step, the IMSI number and the number of the information acquisition device are associated to form a relationship pair of time-information acquisition device number-IMSI number. Specifically, IMSI code data collected by the same information collection device at the same time in the information database are correlated to form a time-information collection device number-IMSI code relationship pair.

And step 210, performing cluster analysis on the incidence relation pairs of all the target users to determine the peer personnel data of each target user.

And performing merging and clustering analysis on all the relation pairs of time-information acquisition equipment number-IMSI code, determining the association relation between the IMSI code and the IMSI code, namely determining an IMSI code data set acquired by the same information acquisition equipment at the same time through a clustering result, determining a common moving track between a target user and the target user by analyzing and comparing longitude and latitude point data corresponding to each IMSI code in the IMSI code data set, and determining the peer personnel data of the target user based on the common moving track. It is to be understood that the peer of the target user is not limited to 1 person.

Further, based on this embodiment, the ship data corresponding to the target user obtained in the foregoing step may be further verified, for example, it is obtained through step 208 that the target user a and the target user B are both in the target ship C, and then the target user a and the target user B are mutually the same-person (the target user B is the same-person of the target user a, and the target user a is the same-person of the target user B), on this basis, if the target user B exists in the same-person of the target user a calculated in step 210, it is proved that the determination result that the target user a and the target user B are both in the target ship C obtained in step 209 is relatively accurate, and if the target user B does not exist, it is indicated that the calculation and the matching are required again.

In the embodiment, the second identification code of the target user, the information acquisition equipment and the acquisition time are associated to obtain an association relationship pair, all the association relationship pairs are subjected to cluster analysis to determine the peer personnel data of the target user, and the ship data corresponding to the target user is further verified based on the peer personnel data of the target user, so that the processing precision of the water area data is greatly improved.
