Specifically, the network data includes one or more of signal strength, network format, and network latency.

when the system type is out of service, recording the second score as zero;
when the system type is 4G system, 3G system or 2G system, setting up three values from big to small correspondingly, and selecting the value corresponding to the current system type as the second score.

and the time delay ranges of the time delay sections are from small to large, a plurality of values from large to small are correspondingly set, and the value corresponding to the time delay section where the current time delay value is positioned is selected and recorded as the third score.
In this embodiment, the calculation manners of the first score, the second score and the third score are given, and in particular, please refer to the following table:
wherein:
when no signal exists, the first score value is recorded as 0; when there is a signal, the value of the intensity value plus one is denoted as the first score, csq+1.
And when the system type of the network is out of service, recording the second score as 0, and when the system type of the network is 4G system, 3G system or 2G system, correspondingly setting three values from large to small, namely 34, 26 and 18, and selecting a value corresponding to the current system type as the second score based on the three values.
When the delay value is 0 or-1 (wherein, -1 represents an error), the third score value is 0; the time delay ranges in a plurality of time delay intervals are from small to large, and the time delay ranges are correspondingly set from small to largeA plurality of values from large to small, i.e., [0, 25) range, [25,150) range, [150,500) range, [500, 1000) range, and [1000, ++ infinity) range is respectively to the value that should be set is that, 34,15. 10 and 5, based on which a value corresponding to the delay interval in which the current delay value is located is selected and noted as the third score.
In this embodiment, one or more of the first score, the second score, and the third score are obtained at a preset frequency within the preset time period.
In the present embodiment, an average value of one or more of the plurality of first scores, the plurality of second scores, and the plurality of third scores is used as the evaluation score.
Specifically, for example, the sum of one of the first score, one of the second score, and one of the third score is used as the evaluation score. Alternatively, the sum of one of the first score, one of the second scores, and one of the third scores is taken as one group, and the average value of the plurality of groups is calculated as the evaluation score.
Based on the above-mentioned score setting scheme, in a specific scenario, if the unmanned aerial vehicle device is currently registered as a 4G network, CSQ is 31 (i.e., RSSI is greater than or equal to-53 dBm), and the ping value (the target address may be ping www.baidu.com) is less than 25 ms, the corresponding evaluation score is 100 minutes. In another specific scenario, if the drone device is currently registered in the 3G network, CSQ is 19 (i.e., RSSI is-75 dBm), and ping value is 150 ms, then the corresponding score of evaluation is 60 points.
For example, if the evaluation is continuously made to be lower than 60 minutes in the detection period of 12 seconds continuously performed for the current operator network, the network is determined to be poor, and at this time, the switching is performed in the order of the above three operator networks.
For another example, after the three operator networks are registered in turn, the evaluation score within 10 seconds is obtained, and one operator with the highest score is selected and switched; optionally, if the evaluation score of the current operator is greater than 60 and less than 5 score lower than the highest score of the operator, it is determined that handover is not necessary, frequent network interruption is avoided, and at this time, the current operator network is kept continuously.
