In this embodiment, the above three operator networks are taken as an example for explanation. Firstly, evaluating the three operator networks by the current unmanned aerial vehicle equipment, wherein the evaluation mode is that the three operator networks are configured on a wireless communication module of the current unmanned aerial vehicle equipment successively according to a preset sequence, and when each operator network is configured and successfully accesses the network, the evaluation score of each operator network is obtained, namely, the network quality of the current operator network is measured in a quantitative mode; then, whether the evaluation scores of the three operator networks meet a first preset condition or not is judged, and the operator network meeting the first preset condition is used as the current operator network of the unmanned aerial vehicle device.
Optionally, the first preset condition is that whether the evaluation score exceeds a first preset value, and at this time, the operator network with the evaluation score exceeding the first preset value is taken as the current operator network; optionally, the first preset condition is that when the evaluation score is higher than the first preset value, the evaluation score is in a difference relationship with the first preset value, and at this time, the operator network with the difference larger than the second preset value is taken as the current operator network. Optionally, the first preset condition may also be a difference relationship between the evaluation score and other evaluation scores when the evaluation score is higher than the first preset value, and at this time, the operator network of which the difference is greater than the third preset value is taken as the current operator network.

In this embodiment, the evaluation scores of the three operator networks are obtained again, and the current operator network is determined according to the first preset condition; optionally, after the evaluation scores of the three operator networks are obtained again, selecting the operator network with the highest evaluation score as the current operator network, and updating the current operator network in time according to a second preset condition; optionally, after the evaluation scores of the three operator networks are obtained again and the current operator network is determined according to the first preset condition, the current operator network is updated in time according to a second preset condition.
EXAMPLE five
Based on the foregoing embodiment, the step of determining the first score according to the strength value of the signal strength includes:
when the intensity value has no signal, recording the first score as zero;
when the intensity value has a signal, the value obtained by adding one to the intensity value is recorded as the first score.
The step of determining the second score according to the format type of the network format further includes:
when the standard type is out of service, recording the second score as zero;
and when the system type is a 4G system, a 3G system or a 2G system, correspondingly setting three values from large to small, and selecting the value corresponding to the current system type to be recorded as the second score.
The step of determining the third fractional value according to the delay value of the network delay further includes:
when the time delay value is zero or error occurs, recording the third score as zero;
and correspondingly setting a plurality of values from large to small for the time delay ranges of the plurality of time delay intervals from small to large, and selecting the value corresponding to the time delay interval where the current time delay value is positioned as the third score.
In this embodiment, a calculation manner of the first score, the second score and the third score is given, and specifically, please refer to the following table:
wherein:
when no signal exists, the first score is recorded as 0; when there is a signal, the value of the intensity value plus one is recorded as the first score, i.e., CSQ + 1.
When the network type is a non-service type, the second score is recorded as 0, when the network type is a 4G system, a 3G system or a 2G system, three values from large to small, namely 34, 26 and 18, are correspondingly set, and based on the three values, the value corresponding to the current system type is selected and recorded as the second score.
(iv) when said delay value is 0 or-1 (wherein-1 represents an error), noting that said third score is 0; the time delay ranges in the time delay sections are from small to large, and a plurality of values from large to small, namely, a range of [0,25), a range of [25,150), a range of [150,500), a range of [500,1000) and a range of [1000, + ∞) are correspondingly set respectively to 34, 34,
15. And 10 and 5, selecting a value corresponding to the time delay interval in which the current time delay value is positioned as the third score.
In this embodiment, one or more of the first score, the second score, and the third score are obtained according to a preset frequency within the preset time period.
In this 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 scores, one of the second scores, and one of the third scores is used as the evaluation score. Alternatively, the evaluation score is calculated by taking the sum of one of the first scores, one of the second scores, and one of the third scores as a group and calculating the average of the plurality of groups.
Based on the above score setting scheme, in a specific scenario, if the unmanned aerial vehicle device is currently registered as a 4G network, the CSQ is 31 (that is, the RSSI is greater than or equal to-53 dBm), and the ping value (the destination address may be ping www.baidu.com) is less than 25 milliseconds, the corresponding evaluation score is 100. In another specific scenario, if the drone device is currently registered in the 3G network, the CSQ is 19 (i.e., RSSI is-75 dBm), and the ping value is 150 milliseconds, the corresponding evaluation score is 60.
For example, if the duration of the continuous 12-second detection period performed for the current operator network is continuously evaluated to be less than 60 minutes, it is determined that the network is bad, and then the handover is performed in the order of the three operator networks.
For another example, after the three operator networks are sequentially registered, one operator with the highest score is selected and switched according to the evaluation score within 10 seconds; optionally, if the evaluation score of the current operator is greater than 60 scores and is less than 5 scores lower than the operator score with the highest score, it is determined that handover is not necessary, and frequent network interruption is avoided, and at this time, the current operator network is continuously maintained.
