Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention.
Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In the description of the present application, it should be noted that, if the terms "upper", "lower", and the like indicate an azimuth or a positional relationship based on the azimuth or the positional relationship shown in the drawings, or an azimuth or the positional relationship that is commonly put when the product of the application is used, it is merely for convenience of description and simplification of the description, and does not indicate or imply that the apparatus or element to be referred to must have a specific azimuth, be configured and operated in a specific azimuth, and therefore should not be construed as limiting the present application.
Furthermore, the terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, without conflict, features in embodiments of the present application may be combined with each other.
In the related art, the duration of the battery is estimated by sampling the current or the voltage at a certain time, and the method can only adapt to specific application scenes, for example, the quality of the unmanned aerial vehicle is kept unchanged, the external interference is zero, or the posture of the unmanned aerial vehicle is unchanged. If the quality of the unmanned aerial vehicle changes in a nonlinear manner, the residual capacity can be calculated inaccurately by simply using the voltage or the current sampled back for a certain time.
For example, when the plant protection unmanned aerial vehicle takes off in full load, the motor needs to do more work in full load, so that the required current can be increased, the residual time calculated by the sampled current is lower, and when the plant protection unmanned aerial vehicle works in flight, the work required by the motor is reduced along with the reduction of the quality of a medicine chest, and the residual time calculated according to the current is higher; similarly, for a vertical-up fixed wing unmanned aerial vehicle with two flight modes, in a multi-rotor state, the required current is far higher than the current in the fixed wing state, and the estimated remaining time of the battery is far shorter than the estimated remaining time in the fixed wing state in the multi-rotor state, so that the current or voltage sampled at a certain moment is simply used for estimating the remaining time, and the actual current or voltage at the next moment cannot be accurately predicted, so that the currently estimated remaining time is inaccurate. And the remaining time is affected by the sampling value at the next moment to cause the problem of abrupt change of the estimated remaining time.
The embodiment of the application provides a method for determining the endurance time of an unmanned aerial vehicle, wherein the obtained preset flight information of each leg in a target route can indicate the electric quantity consumption information of each leg and time consumption information, the electric quantity consumption information indicated in the preset flight information of each leg in the target route is subdivided, the flight states of different legs are changed, the electric quantity consumption information is also different, and the endurance time determined based on the current electric quantity of a battery and the preset flight information of each leg is also more accurate.
According to the method for determining the endurance time of the unmanned aerial vehicle, the execution main body can be processing equipment, and the processing equipment can be a controller arranged on the unmanned aerial vehicle; the device may also be independent of the drone and may communicate with the drone, for example, the processing device may be a terminal or a server; other devices with processing functions may be used, and the embodiments of the present application do not specifically limit this.
It should be noted that, the method for determining the endurance time of the unmanned aerial vehicle provided by the embodiment of the application can be applied to a scene where the unmanned aerial vehicle does not fly along the target route, can also be applied to a scene where the unmanned aerial vehicle flies along the target route, and can also be applied to other scenes, and the embodiment of the application does not limit the method specifically.
