Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
The first embodiment is as follows:
in order to explain the technical scheme of the invention, the embodiment of the invention provides a flight operation data fusion method.
Fig. 1 is a schematic flow chart of a flight operation data fusion method according to an embodiment of the present invention.
Referring to fig. 1, a flight operation data fusion method provided by an embodiment of the present invention may include the following steps:
s11, obtaining target flight operation data in the air traffic control production system, and dividing the flight operation data into scheduled flight operation data and monitoring flight operation data according to functions.
Various types of flight operation data can be continuously generated in the operation process of the civil aviation air traffic control production system. At present, most of the data are stored and applied independently, and the effective integration of the data is lacked. Based on the method, in the air traffic control production system, the target flight operation data are obtained, and the obtained flight operation data are divided into scheduled flight operation data and monitoring flight operation data according to functions.
For example, to ensure the comprehensiveness of data fusion, in this embodiment, flight operation data of multiple production systems, such as target flight operation data, may be acquired, and may include: the flight planning system comprises one or more of advanced flight planning data generated by the flight planning processing system, flight message data generated by the rebroadcasting system, flight dynamic data generated by the automation system, flight ground operation data generated by the tower electronic process unit system, flight cooperative release data generated by the CDM system, flight stop data generated by the airport production scheduling system or flight comprehensive track number generated by the automation system. Preferably, in the present embodiment, all the data described above may be described as target data.
Specifically, the flight plan refers to a flight that an aircraft performs a direct flight from place a to place B, and is called a primary flight plan. The advance flight plan is a plan in which all flight plans executed on the same day are usually generated in advance on the previous day, and is referred to as an advance flight plan. The message data refers to the message which is an information unit transmitted and exchanged in the civil aviation internal data network, such as flight take-off time, landing time and the like. The flight dynamic data refers to flight status that the flight continuously updates in the flight process, such as predicted arrival time, belonging control area, etc., and changes of the flight status become flight dynamic. The ground operation data refers to a taxi phase of a flight from pushing out for driving to taking off from the ground and from landing to sliding back to the flight seat, and is called a ground operation phase, and the relevant state change data generated in the ground operation phase is called ground operation data. The cooperative release data refers to flight release data formed under the cooperative action of a plurality of different units. The stop data refers to the flight stop or the station data to be stopped. The comprehensive track data refers to final position data generated by fusing flight position data detected by a plurality of radars according to a certain rule and is called as comprehensive track data.
In this embodiment, when dividing the target data, the target data may be divided into two types, namely scheduled flight operation data and monitoring flight operation data according to functions. For example, the scheduled flight operation data may include: the method comprises the steps of providing scheduled flight planning data, scheduled flight message data, scheduled flight dynamic data, scheduled flight ground operation data, scheduled flight cooperative release data and scheduled flight stop data. The monitoring class flight operation data comprises flight integrated track data.
S12, extracting a planning main key from the planning type flight operation data, and constructing a main key mapping table of the planning main key and the radar main key.
The planning main key is composed of a plurality of information fields, and each type of scheduled flight operation data contains the information fields. The radar main key is composed of a plurality of information fields, and each type of monitoring type flight operation data contains the information fields. The secondary code is a four-digit octal code distributed by a certain control unit at a certain stage of flight operation, and can be used as an identifier for distinguishing different flights in the current airspace of a single control area.
In an embodiment of the present invention, the plan primary key may include: one or more of the four fields of flight number, takeoff airport, landing airport, or takeoff time are described, and in the present embodiment, the plan home key includes all of the four fields as an example.
In a specific embodiment, a plan Primary Key (PK) may be extracted from the flight schedule data as a basis for associating the flight schedule identifier with different types of data. In the embodiment, the planning main key PK is composed of four fields of flight number, takeoff airport, landing airport and takeoff time, and the planning type flight operation data generally includes these four fields.
Further, if the number of the same main planning keys in all main planning keys of the different scheduled flight operation data is greater than the preset threshold value with the same number, the different scheduled flight operation data are associated and fused according to the preset reference. For example, for the case where the individual scheduled flight run data may include multiple departure time related fields, the priority selected by the present invention is estimated departure time (ETOT) > time-in-flight (STOD) > actual departure time (ATOT), i.e., if the data includes an ETOT field and is not null, the departure time field of the primary key is ETOT, otherwise if the data includes a STOD field and is not null, the departure time field of the primary key is STOD, otherwise the departure time field of the primary key is ATOT. Based on the selection method of the plan main key, the association and fusion rules of the operation data of the scheduled flights are as follows: if the flight numbers of two pieces of scheduled flight operation data are the same, the takeoff airports are the same, the landing airports are the same, and the takeoff time difference is less than 8 hours (the actual takeoff time delay caused by flight delay is solved), the two pieces of data are considered to belong to the same flight schedule and are associated and fused.
And S13, extracting the radar main key from the monitoring type flight operation data.
In the embodiment of the invention, a radar main key (RK) is extracted from the monitoring data to be used as the identification of the flight plan. Similarly, in the present embodiment, the radar primary key includes three fields as an example, and the description is given by taking the example that the radar primary key includes three fields.
In order to realize the association and fusion of the monitoring type flight operation data and the planning type flight operation data, the invention provides a primary key mapping table which is used for maintaining the mapping relation between the radar primary key and the planning primary key belonging to the same flight plan at the current time period. Fig. 2 is a schematic diagram of a primary key mapping table according to an embodiment of the present invention.
Referring to fig. 2, for a plurality of pieces of scheduled flight operation data and monitoring type flight operation data, a schedule primary key may be extracted for each piece of scheduled flight operation data, for example, PK 1: (flight number 1, takeoff airport 1, landing airport 1, takeoff time 1), and so on. Extracting a radar main key for each piece of monitoring class flight operation data, wherein the radar main key comprises the following steps of RK 1: (flight number 1, secondary code 1, data source area 1), and so on. In the master key map, the radar master key RK1 and the plan master key PK1 are mapped to each other.
And S14, fusing the scheduled flight operation data and the monitored flight operation data according to a preset fusion rule through the radar main key and the main key mapping table.
Because part of scheduled flight operation data simultaneously comprises four fields of the scheduled main key and three fields of the radar main key, when the scheduled data is processed, the radar main key and the corresponding scheduled main key (the takeoff time field is selected according to the priority) in the data are updated into the main key mapping table. When the monitoring type flight operation data is processed, the radar main key is extracted from the monitoring type flight operation data, the corresponding plan main key is found in the main key mapping table, then the processing is carried out according to the association of the plan type flight operation data and the set fusion rule, and finally the fusion of the monitoring type flight operation data and the plan type flight operation data is realized.
Further, on the basis of the above embodiment, the method further includes: judging whether a planning main key can be extracted from the planning type flight operation data; if so, searching a corresponding entry in the fusion rule according to the plan main key, and fusing the plan type flight operation data with the corresponding entry; judging whether a radar main key can be acquired from the scheduled flight operation data or not; if the radar main key can be obtained, adding a plan main key and a radar main key in a mapping table; and if not, performing exception processing on the scheduled flight operation data.
Further, on the basis of the above embodiment, the method further includes: judging whether a radar main key can be acquired from the monitoring type flight operation data; if the radar main key is obtained, searching the matching entry in the mapping table by the radar main key; searching corresponding items in the fusion rule according to the plan main key in the matched items; and fusing the monitoring flight operation data and the corresponding entries according to the rule of the fusion rule.
Specifically, a fused data storage table may be established to store flight operation fused data using a flight plan as an entry provided by the embodiment of the present invention.
For example, fig. 3 is a schematic flowchart of a fusion process of scheduled flight operation data according to an embodiment of the present invention.
Referring to fig. 3, after receiving a piece of scheduled flight operation data, analyzing the scheduled flight operation data, analyzing each field of the analyzed scheduled flight operation data, determining whether a scheduled key can be obtained in the scheduled flight operation data, and if the scheduled key cannot be extracted, performing exception handling on the scheduled flight operation data, and ending the data processing.
If the PLAnKey can be formed by four fields of flight number, take-off airport, landing airport and take-off time, whether the PLAnKey of a flight plan entry can be matched is searched in the existing fusion data storage table according to the formed PLAnKey, and the matching rule is that the flight number is the same, the take-off airport is the same, the landing airport is the same and the take-off time is within 8 hours.
If the number of the matched items is 0, creating a new flight plan item for the new data in the fusion data storage table, taking a PlanKey formed in the new data as a PlanKey of the newly-created flight plan item, attaching all fields in the new data to the newly-created flight plan item, judging whether the newly-received data has three RadarKey forming fields of a flight number, a secondary code and a data source area, and if so, adding a mapping item in a primary key mapping table. If the primary key mapping table has the mapping item of the RadarKey, only the mapping update of the PlanKey is carried out, and if the mapping item does not exist, a mapping item is newly established for the RadarKey and the PlanKey.
And if the number of the matched entries is 1, performing fusion processing on the matched flight plan entries and newly received flight operation data in the fusion data storage table, namely if new fields exist in the new data, directly attaching the new fields to the matched flight plan entries, and if the fields of the new data also exist in the matched flight plan entries, determining whether to perform field data coverage according to a set priority rule. And judging whether the newly received data has three composing fields of RadarKey of flight number, secondary code and data source area.
If the number of matched entries is more than 1, logging abnormal data and performing necessary feedback.
For example, fig. 4 is a schematic view of a fusion process of monitoring flight operation data according to an embodiment of the present invention.
Referring to fig. 4, when a piece of monitored flight operation data is received, each field of the monitored flight operation data is analyzed, whether a radar primary key can be extracted from the monitored flight operation data is judged, that is, whether a flight number, a secondary code, and a data source region can form a RadarKey key is judged, and if the RadarKey key exists, a mapping entry of the RadarKey key is searched in an existing primary key mapping table according to the formed RadarKey key.
And if the number of the matched items is 0, ending the data processing flow.
If the number of the matched items is 1, searching whether the PLAnKey of the flight plan item can be matched in the existing fusion data storage table according to the PLAnKey mapped by the matched items, wherein the matching rule is that the flight number is the same, the takeoff airport is the same, the landing airport is the same, and the takeoff time difference is within 8 hours, if the number of the matched items is 0, creating a new flight plan item for the new data in the fusion data storage table, taking the PLAnKey mapped by the RadarKey as the PLAnKey of the newly-built flight plan item, and attaching all fields in the new data to the newly-built flight plan item; if the number of the matched items is 1, performing fusion processing on the matched flight plan entry and newly received flight operation data in the fusion data storage table, namely if new data has a new field, directly attaching the new data to the matched flight plan entry, and if the field of the new data also exists on the matched flight plan entry, determining whether field data coverage is performed or not according to a set priority rule; if the number of matched entries is more than 1, logging abnormal data and performing necessary feedback.
If the number of matched entries is more than 1, logging abnormal data and performing necessary feedback.
Fig. 5 is a schematic view of flight operation data fusion provided in the embodiment of the present invention. Referring to fig. 5, for example, when the monitored flight operation data is G1, the radar master key is extracted as RK1, and the planned master key corresponding to RK1 is PK1, so that the planned flight operation data with the planned master key PK1 can be found in the planned flight operation data, as shown in fig. 5, the planned flight operation data with the planned master key PK1 is preplanned (a1, PK1), message data (B2, PK1), flight dynamics (C3, PK1), ground operation (D1, PK1), collaborative release (E2, PK1), and airplane stop position (F3, PK1), so that the fused data obtained by fusing the planned flight operation data and the monitored flight operation data is:
flight plan 1(PK 1): (A1, B2, C3, D1, E2, F3, G1).
