[0073] Specifically, the flight altitude range and speed range of the aircraft are obtained according to the aircraft performance, the restricted flight altitude and speed range of the flight mission execution area are obtained according to the aircraft airspace management regulations information data of the flight mission execution area, and whether the flight mission can be performed at this time is judged according to the flight mission execution time. If the weather is bad, the mission is canceled. If the weather allows the aircraft to fly, the safe altitude and speed for the flight on that day are obtained to determine the flyable altitude and speed values of the aircraft in the flight mission execution area.
[0074] Furthermore, the range of values of the aircraft's flight altitude is as follows:
[0075] (hx min ,hy min ) max ≤h≤(hx max ,hy max ,ht max ) min

[0080] Step S6: The control console generates an optimal flight route for the aircraft according to the flight mission execution area marked chart and the flyable altitude range and the flyable speed range;
[0081] Furthermore, the control console generates the following sub-steps for the optimal flight route of the aircraft based on the flight mission execution area marked chart and the flyable altitude range and the flyable speed range:
[0082] Step S61: The control console obtains the optimal flight route when encountering obstacles based on the flight mission execution area marked on the chart, the flyable altitude range, and the flyable speed range;
[0083] Specifically, according to the flyable altitude range and the flight mission execution area annotated chart, the obstacle information that is not within the flyable altitude range is obtained, and obstacles higher than the maximum flyable altitude are marked on the flight mission execution area annotated chart as areas that need to be detoured; obstacles lower than the minimum flyable altitude are marked on the flight mission execution area annotated chart as passable areas; according to the flyable altitude range and the flight mission execution area annotated chart, the obstacle geographic information data within the flyable altitude range is obtained and the obstacle height, shape and horizontal area at each height are obtained, and the flight plan for the aircraft encountering the obstacle is determined according to the shape of the obstacle. For example, if the aircraft encounters an obstacle of the type of high-voltage line during flight, the flight altitude can be changed to avoid it. If the aircraft encounters an obstacle of the type of high-rise building during flight, it can choose to bypass the obstacle from above or from the side. The choice of bypassing the obstacle from above or from the side requires comparing the flight distances of the two plans to select the optimal flight plan.
[0084] Furthermore, the flight distance from the side to bypass the obstacle is expressed as follows:
[0085]
[0086] Specifically, the obstacle is abstracted as a horizontal ellipse, rl is the flight distance of the sideways obstacle, and d h is the distance between any two points of an obstacle passing through the center of the obstacle encountered by the aircraft when it flies to a certain altitude, (d h ) max is the longest distance between any two points of the obstacle passing through the center of the obstacle, (d h ) min is the shortest distance between any two points of the obstacle passing through the center point of the obstacle and perpendicular to the longest line segment, zj is the distance the aircraft needs to be away from the obstacle to change its heading, and θ is the angle between the aircraft and the center point of the obstacle before and after the aircraft bypasses it.
[0087] Furthermore, the expression for the flight distance to bypass obstacles from above is as follows:
[0088] sl=π×(zh-fh+zj,qh+zj) min +2×[(zh-fh+zj,qh+zj) max -(zh-fh+zj,qh+zj) min ]
[0089] Specifically, sl is the flight distance around the obstacle above, zh is the height of the obstacle encountered, fh is the flight altitude of the aircraft, zj is the distance from the obstacle that the aircraft needs to change its heading, and qh is the straight-line distance before and after the aircraft passes over the obstacle.

The flight route of obstacles in this area is marked on the flight mission execution area annotation chart.
[0091] Step S62: The control console obtains the optimal flight route according to the flight mission execution area marked chart and the optimal flight route when encountering obstacles;
[0092] Specifically, the flight route between the take-off point and the landing point of the aircraft is fully marked on the marked chart of the flight mission execution area using the ant algorithm according to the marking information of the marked chart of the flight mission execution area, the flight time and energy consumption of the aircraft for each route are calculated, and the optimal flight route is selected.

[0096] Specifically, the energy of the aircraft is compared with the energy consumption of the flight route, and routes whose energy consumption is greater than the energy of the aircraft are eliminated.
[0097] Furthermore, the total flight time of each flight route is expressed as follows:

[0100] Specifically, the energy consumption of the flight route is divided into ten levels, and the lower the energy consumption, the higher the level; the flight route time is divided into ten levels, and the shorter the time, the higher the level.
[0101] Furthermore, the optimal flight path score expression is as follows:
[0102] FS=(60%×snd1+40%×hs1,…,60%×sndi +40%×hs i ) max
[0103] Specifically, FS is the flight route score, snd is the flight route energy consumption level, hs is the flight route time level, and i is the flight route number, wherein the flight route energy consumption level snd has a weight of 60%, and the flight route time level hs has a weight of 40%.
[0104] Specifically, a flight route with the highest score is calculated through an optimal flight route score expression, and an optimal flight route is determined according to the flight mission.
