1 is a schematic flowchart of a method for evaluating a flight conflict release control instruction according to an embodiment of the present invention; as shown in FIG. 1 , the method includes the following steps:

S1, read the control instruction, and obtain the conflict relief track;

S2, calculate the flight conflict index; specifically including the conflict resolution track flight conflict index and the planned track flight conflict index;

S3, on the basis of the flight conflict index, construct a flight conflict evaluation index system with three indicators of effectiveness, accuracy and timeliness.

Specifically, after the flight conflict is resolved, the control instruction is read to obtain the conflict resolution track, and the flight conflict index is calculated for the planned track and the conflict resolution track respectively. The three indicators are combined with the time and space dimensions to build a flight conflict evaluation indicator system to achieve a comprehensive and detailed evaluation of the conflict release control order.

After calculating the above four sub-indices, the four sub-indices of the flight conflict are determined with reference to the Civil Aircraft Incident Standard. conflict index.

Further, in step S3, the validity index defines the conflict index decrease ratio CID, and the calculation formula is:

Among them, on the basis of calculating the flight conflict index for the planned track and the conflict resolution track, draw two flight conflict index trends; select the conflict index trend peak point of the planned track and the conflict resolution track, that is, the flight conflict occurs in the track. The maximum possibility of the flight conflict; the maximum conflict index of the planned track is CI _max , and the maximum conflict index of the conflict resolution track is CI′ _max , when 0<CID<1, it indicates that the possibility of flight conflict decreases, and the closer to 0, the diversion The lower the possibility of post-conflict occurrence, the better the effectiveness of the relief; when CID≥1, it indicates that the conflict relief track after the control instruction is issued does not reduce the possibility of flight conflict, and the flight conflict relief fails;

Accuracy, define the target track deviation ratio as TDD, and the calculation formula is:

Among them, the planned flight length is ITL, and the conflict resolution track length is PTL. Obviously, it can be judged that the target track deviation ratio TDD is greater than 0. The closer to 0, the closer the conflict resolution track is to the planned track, and the better the resolution accuracy;

Timeliness, defines the instruction time delay ratio ITD, and the calculation formula is:

Among them, according to the flight conflict index of the planned track, the starting time in the conflict time period is taken as the conflict occurrence time as the FCT, the current time as the PT, and the time when the control command is issued as the CIT. Through simple analysis, it can be judged that 0<ITD< 1. The closer the ITD is to 0, the faster the command time is issued, the better it is for conflict avoidance, and the better the release timeliness.
