After step S101 and before step S102, the method includes:
s1020, acquiring height data of a target signal base station, relative position data of the target signal base station and an unmanned aerial vehicle route, position data and height data of the unmanned aerial vehicle route;

When a plurality of antennas are installed on the target signal base station, step S103 includes:

s105, when the logistics unmanned aerial vehicle performs flight test on the unmanned aerial vehicle route, acquiring route signal intensity data corresponding to the unmanned aerial vehicle route acquired by the unmanned aerial vehicle;
s106, judging whether the route signal intensity data is smaller than a set threshold value, if so, determining the route position corresponding to the route signal intensity data, and adjusting the angle of an antenna on a target signal base station which can cover the route position.
The following is a detailed description of the situation:
because the number of signal base stations laid on the ground by an operator is quite dense, after the unmanned aerial vehicle route is planned, a certain number of proper target signal base stations are selected in a certain range (such as within 5 km) around the unmanned aerial vehicle route by combining surrounding terrain features, high-rise buildings and other influencing factors.
After the appropriate target signal base stations are selected, the target signal coverage and the target signal height of each target signal base station, which need to cover the unmanned aerial vehicle route, are determined. Because the height of the logistics unmanned aerial vehicle in the cruising stage is basically fixed, the height of each target signal base station is also fixed, and therefore, after the antenna on the target signal base station is adjusted to a certain angle, the whole unmanned aerial vehicle route can be completely covered.
When the signal emission direction of the antenna is toward the sky direction, the shielding object is small, the antenna with the same power is used, and the signal coverage area is larger than the antenna area toward the ground, so that the signal emission direction of the antenna is adjusted to be toward the sky direction.
Since the signal strength of the coverage area is inversely related to the distance from the antenna, the signal strength of the coverage area is weaker as the distance is greater, so that the signal coverage areas corresponding to two adjacent target signal base stations should overlap. As shown in fig. 7, T1 and T2 respectively represent two target signal base stations, a represents the starting point of the air route, b represents the end point of the air route, the left circular area S1 is the signal coverage corresponding to the target signal base station T1, the right circular area S2 is the signal coverage corresponding to the target signal base station T2, and the middle area S is the signal coverage common to the target signal base stations T1 and T2, so that the signal full coverage of the air route of the unmanned aerial vehicle is ensured, and if the distance between T1 and the starting point a is about 8km, the distance between T2 and the starting point b is about 4km, the distance between T1 and T2 is about 53km, and the signal transmission radius ranges of the target signal base stations T1 and T2 are all 50km, the distance between two adjacent target signal base stations T1 and T2 is between 10 km and 40km, so that the requirements can be satisfied.
After the position of the target signal base station is determined, determining a target signal coverage area corresponding to the target signal base station according to the position of the air route, the height of the target signal base station and the relative position of the target signal base station and the air route, determining the elevation angle of an antenna erected on the target signal base station by an operator according to the target signal coverage area, and adjusting the angle of the antenna according to the calculated elevation angle.
As shown in fig. 8, 3 target signal base stations TA, TB, TC are selected along the periphery of one unmanned aerial vehicle route, and the whole unmanned aerial vehicle route can be covered. Wherein, two opposite antennas can be arranged on each target signal base station, and the signals in two opposite directions of the route are respectively and repeatedly covered.
The shortest distance between the target signal base station TB and the route is about 3km, the area, close to the route, of the target signal base station is mainly cultivated land, no high-rise building exists, the topography is flat, the surrounding topography is uniformly distributed, and the target signal base station TB is an ideal choice for covering the route signals. The flying height of the logistics unmanned aerial vehicle is about 300m, the iron tower height is about 45m, the erection height of the actual target signal base station is about 35m, and the whole course elevation angle calculation result of the antenna on the target signal base station is as follows:
| Direction | Elevation angle (°) of antenna |
| Route origin → TB | 0.69–5 |
| TB-receiving |
5–0.46 |
After the antenna angle on the target signal base station is set, the pipeline area of the unmanned aerial vehicle route should be covered with signals in theory. However, because the relative positions of each point on the route from the antenna are different, the signal intensity distribution is different, and whether the whole-course communication data transmission requirement can be met in practice is particularly required, the actual logistics unmanned aerial vehicle is required to carry communication equipment for test flight, and further optimization and correction are performed.
For example, after analyzing the signal intensity data of the route acquired after the communication device is mounted on the logistics unmanned aerial vehicle, as shown in fig. 9 and 10, it can be seen that the signal intensity of the route L at the F area is abnormal, as shown in fig. 10 (the horizontal axis represents time, the unit min, and the vertical axis represents signal intensity in dB), that is, the signal intensity F of the route L at the F area is weak, which indicates that the signal coverage condition of the F area is bad, and the angle of the antenna on the corresponding target signal base station nearby needs to be adjusted or the antenna needs to be newly added so that the signal coverage of the F area meets the requirement. Finally, through repeated experimental optimization, the signal coverage effect of the whole unmanned aerial vehicle route reaches the requirement. As shown in fig. 11 (the horizontal axis represents time, the unit is min, the vertical axis represents signal strength, the unit is dB), the signal strength of the route at the F region is no longer abnormal, and the signal coverage requirement is satisfied, so that the problem of poor signal coverage effect is solved; and by analogy, the problem of full signal coverage of each unmanned aerial vehicle route is finally realized.

Example 6
As shown in fig. 14, the control system for signal coverage of the unmanned aerial vehicle route of the present embodiment is a further improvement of embodiment 5, specifically:
the control system further comprises a signal strength data acquisition module 9 and a judgment module 10.

The following is a detailed description of the situation:
because the number of signal base stations laid on the ground by an operator is quite dense, after the unmanned aerial vehicle route is planned, a certain number of proper target signal base stations are selected in a certain range (such as within 5 km) around the unmanned aerial vehicle route by combining surrounding terrain features, high-rise buildings and other influencing factors.
After the appropriate target signal base stations are selected, the target signal coverage and the target signal height of each target signal base station, which need to cover the unmanned aerial vehicle route, are determined. Because the height of the logistics unmanned aerial vehicle in the cruising stage is basically fixed, the height of each target signal base station is also fixed, and therefore, after the antenna on the target signal base station is adjusted to a certain angle, the whole unmanned aerial vehicle route can be completely covered.
When the signal emission direction of the antenna is toward the sky direction, the shielding object is small, the antenna with the same power is used, and the signal coverage area is larger than the antenna area toward the ground, so that the signal emission direction of the antenna is adjusted to be toward the sky direction.
Since the signal strength of the coverage area is inversely related to the distance from the antenna, the signal strength of the coverage area is weaker as the distance is greater, so that the signal coverage areas corresponding to two adjacent target signal base stations should overlap. As shown in fig. 7, T1 and T2 respectively represent two target signal base stations, a represents the starting point of the air route, b represents the end point of the air route, the left circular area S1 is the signal coverage corresponding to the target signal base station T1, the right circular area S2 is the signal coverage corresponding to the target signal base station T2, and the middle area S is the signal coverage common to the target signal base stations T1 and T2, so that the signal full coverage of the air route of the unmanned aerial vehicle is ensured, and if the distance between T1 and the starting point a is about 8km, the distance between T2 and the starting point b is about 4km, the distance between T1 and T2 is about 53km, and the signal transmission radius ranges of the target signal base stations T1 and T2 are all 50km, the distance between two adjacent target signal base stations T1 and T2 is between 10 km and 40km, so that the requirements can be satisfied.
After the position of the target signal base station is determined, determining a target signal coverage area corresponding to the target signal base station according to the position of the air route, the height of the target signal base station and the relative position of the target signal base station and the air route, determining the elevation angle of an antenna erected on the target signal base station by an operator according to the target signal coverage area, and adjusting the angle of the antenna according to the calculated elevation angle.
As shown in fig. 8, 3 target signal base stations TA, TB, TC are selected along the periphery of one unmanned aerial vehicle route, and the whole unmanned aerial vehicle route can be covered. Wherein, two opposite antennas can be arranged on each target signal base station, and the signals in two opposite directions of the route are respectively and repeatedly covered.
The shortest distance between the target signal base station TB and the route is about 3km, the area, close to the route, of the target signal base station is mainly cultivated land, no high-rise building exists, the topography is flat, the surrounding topography is uniformly distributed, and the target signal base station TB is an ideal choice for covering the route signals. The flying height of the logistics unmanned aerial vehicle is about 300m, the iron tower height is about 45m, the erection height of the actual target signal base station is about 35m, and the whole course elevation angle calculation result of the antenna on the target signal base station is as follows:
| Direction | Elevation angle (°) of antenna |
| Route origin → TB | 0.69–5 |
| TB-receiving |
5–0.46 |
After the antenna angle on the target signal base station is set, the pipeline area of the unmanned aerial vehicle route should be covered with signals in theory. However, because the relative positions of each point on the route from the antenna are different, the signal intensity distribution is different, and whether the whole-course communication data transmission requirement can be met in practice is particularly required, the actual logistics unmanned aerial vehicle is required to carry communication equipment for test flight, and further optimization and correction are performed.
For example, after analyzing the signal intensity data of the route acquired after the communication device is mounted on the logistics unmanned aerial vehicle, as shown in fig. 9 and 10, it can be seen that the signal intensity of the route L at the F area is abnormal, as shown in fig. 10 (the horizontal axis represents time, the unit min, and the vertical axis represents signal intensity in dB), that is, the signal intensity F of the route L at the F area is weak, which indicates that the signal coverage condition of the F area is bad, and the angle of the antenna on the corresponding target signal base station nearby needs to be adjusted or the antenna needs to be newly added so that the signal coverage of the F area meets the requirement. Finally, through repeated experimental optimization, the signal coverage effect of the whole unmanned aerial vehicle route reaches the requirement. As shown in fig. 11 (the horizontal axis represents time, the unit is min, the vertical axis represents signal strength, the unit is dB), the signal strength of the route at the F region is no longer abnormal, and the signal coverage requirement is satisfied, so that the problem of poor signal coverage effect is solved; and by analogy, the problem of full signal coverage of each unmanned aerial vehicle route is finally realized.
In this embodiment, through establishing many unmanned aerial vehicle airlines at every website, select the target signal basic station, and through the antenna angle on the target signal basic station of adjustment operator, guarantee that commodity circulation unmanned aerial vehicle can be covered by the signal is full at the cruising altitude that unmanned aerial vehicle airlines correspond, simultaneously, the second unmanned aerial vehicle airlines also realize signal full coverage between different websites, need not extensive signal coverage promptly, only need to carry out signal coverage to the pipeline type region that forms along unmanned aerial vehicle airlines can, thereby when guaranteeing steady data communication transmission, the running cost of current commodity circulation unmanned aerial vehicle has been reduced greatly, and the operation mode of having constructed brand-new commodity circulation unmanned aerial vehicle has promoted the development of commodity circulation business based on commodity circulation unmanned aerial vehicle effectively.
