DETAILED DESCRIPTION OF THE INVENTION

The technical solutions of the present invention will be described below in combination with the drawings in various embodiments of the present invention. It should be apparent that the embodiments described herein are only a part rather than all of the embodiments of the present invention. Other embodiments obtained by those having ordinary skill in the art on the basis of the embodiments of the present invention without any inventive efforts should fall within the protection scope of the present invention.
An embodiment of the present invention can automatically obtain meteorological information of a certain target region, and then determine one or more flight parameter candidates of an aerial vehicle which might be limited by meteorological conditions according to the meteorological information, so that a user or the aerial vehicle can select whether to cancel or to modify a flight task according to the requirement of the flight task. The target region may be a region for the aerial vehicle to pass by when flying automatically as the aerial vehicle performs the flight task, or a region specified by the user according to certain requirements.
Referring to FIG. 1, which is a flow chart of a flight instructing method according to embodiments of the present invention, the method according to the embodiments of the present invention may be implemented by an intelligent mobile terminal with a network function for controlling the aerial vehicle, such as a smart phone, a tablet, an intelligent wearable apparatus or the like. Of course, the method may also be implemented by a flight controller with a network communication function disposed on the aerial vehicle. The embodiments of the present invention use an implementation in the intelligent mobile terminal as an example to illustrate the method. Specifically, the method may include the following steps.
S101: obtaining meteorological information of a target flight region.
In one embodiment, the meteorological information of the target flight region may be queried by accessing a server which provides the meteorological information via the Internet or the like. The meteorological information needs to be queried may be all meteorological information provided by the server, and may also be the required meteorological information which is queried or screened out from all meteorological information based on related flight parameters, which may be determined by the intelligent mobile terminal based on the model number and performance of the aerial vehicle.
Alternatively, the intelligent mobile terminal or the aerial vehicle may come with its own meteorological monitoring function, for example, with simple mechanisms for monitoring meteorological information, such as wind speed, wind direction, air temperature, air pressure and the like, so as to implement monitoring of the meteorological information based on these monitoring mechanisms when the aerial vehicle needs to fly in a certain region.
S102: determining a flight-limiting parameter candidate of the aerial vehicle in the target flight region according to the obtained meteorological information.
The mobile terminal may use a preset simulator to evaluate an impact on a flight of a simulated aerial vehicle by a simulative meteorological environment generated by the meteorological information, and thereby calculates and determines one or more flight parameters of the aerial vehicle that might need to be limited (flight-limiting parameter candidate(s)). In the simulator of the mobile terminal, specifically, the meteorological environment may be simulated based on a level of the wind speed, a temperature level of the air temperature and a value of the air pressure, and the simulated meteorological environment may be applied on the simulated aerial vehicle in the simulator, so as to more precisely evaluate the flight-limiting parameter candidate(s).
Of course, in a simple implementation, a mapping table may be provided to include a mapping relationship between the meteorological information and the flight parameters. A one-to-one mapping relationship between the meteorological information (and a level thereof) and the flight parameters may be specifically included in the mapping table. After the meteorological information of the target flight region is obtained, the mapping table is looked up based on the specific data of the meteorological information (for example, wind speed level), and a possible flight-limiting parameter candidate can be obtained. Using the looking up table is relatively quick and convenient to realize.
S103: issuing a flight-limiting indication based on the determined flight-limiting parameter candidate(s).
In some embodiments, S103 may specifically comprise: displaying the determined flight-limiting parameter candidate(s); or issuing a flight-limiting control instruction according to the determined flight-limiting parameters.
In some embodiments, the flight-limiting indication may just be prompting information in a preset format for prompting a user, and the mobile terminal may display the flight-limiting parameter candidate(s) in a list on a display screen as the flight-limiting indication. Suggestion information by the user may be added into the flight-limiting indication. For example, after a visibility information is determined based on a haze level, the suggestion information of a flight altitude limit and/or distance limit is issued. Specifically, if the visibility is 100 m, the flight-limiting indication comprising a flight altitude being limited to 100 m is issued.
It should be noted that, if it is implemented by a flight controller of the aerial vehicle, in S103, the flight controller may send related information to a designated user terminal such that the flight-limiting parameters can be prompted to the user.
The flight-limiting indication information may include a flight control instruction issued based on the flight-limiting parameters and corresponding meteorological information. As described above, after the visibility information is determined based on the haze level, flight control instructions to limit altitude and to limit distance may be generated as the flight-limiting indication, so as to limit the flight altitude and flight distance and the like when the aerial vehicle flies in the target flight region to ensure flight safety.
Further, an alert level may also be displayed correspondingly. For some very dangerous meteorological conditions, for example, a strong wind environment, a red alert and the like is issued. Moreover, in some embodiments, for a good meteorological condition, that is, when no flight-limiting indication is determined, the prompting information of being suitable to fly may be issued.
In addition, the obtained meteorological information may be displayed at a designated position on the display screen, and may further be displayed in the form of a drawing icon, facilitating the user to view intuitively the meteorological condition of the target region.
Accordingly, the embodiments of the present invention may determine the flight-limiting parameters based on the obtained meteorological information of the target flight region, create the flight-limiting indication, and prompt the user in advance or control an unmanned aerial vehicle directly to perform a flight task more safely in the target flight region, ensuring flight safety of the aerial vehicle and meeting requirements of the user of the aerial vehicle on automatic and intelligent meteorological information.
Referring to FIG. 2, which is a flow chart of another flight instructing method according to embodiments of the present invention, the method according to the embodiments of the present invention may be implemented by an intelligent mobile terminal with a network function for controlling the aerial vehicle, such as a smart phone, a tablet, an intelligent wearable apparatus or the like. Of course, the method may also be implemented by a flight controller with a network communication function disposed on the aerial vehicle. Specifically, the method may include the following steps.
S201: obtaining meteorological information of a target flight region.
Specifically, S201 may comprise: using a region where an aerial vehicle currently flies in or a region designated by the user as the target flight region; based on meteorological reference information of the aerial vehicle, accessing a network and searching the meteorological information of the target flight region indicated by the meteorological reference information. The meteorological reference information may include: designated meteorological reference information or meteorological reference information generated based on a type of the aerial vehicle. The meteorological reference information is used for indicating which meteorological information needs to be searched, for example, a wind speed indication, a wind direction indication and the like. In this way, the amount of data to be searched may be smaller.
S202: looking up a flight parameter or parameters associated with the obtained meteorological information according to a preset mapping relationship between the meteorological information and flight parameters.
S203: determining the looked up flight parameter(s) as a flight-limiting parameter candidate(s) of the aerial vehicle in the target flight region.
In some embodiments, specifically, in the preset mapping relationship between the meteorological information and the flight parameters, the mapping relationship between the meteorological information (and a level thereof) and the flight parameters is included. Looking up a flight parameter associated with the obtained meteorological information according to the preset mapping relationship between the meteorological information and flight parameters may comprise: analyzing and determining a meteorological level of the obtained meteorological information; looking up the associated flight parameter in the preset mapping relationship between the meteorological information and the flight parameters based on the meteorological information and the level thereof. For example, a lower level of haze will not be associated with a flight distance range parameter and a flight altitude parameter, and the flight distance range parameter and the flight altitude parameter will not be determined as flight-limiting parameters under the meteorological condition with a lower level of haze.
The determined flight-limiting parameter candidate may comprise any one of or a combination of a flight speed parameter candidate, a flight altitude parameter candidate, and a flight distance range candidate.
S204: issuing a flight-limiting indication based on the determined flight-limiting parameter candidate.
In some embodiments, the flight-limiting indication is directly displayed to the user of the aerial vehicle as prompting information.
S205: judging whether a flight path in the target flight region is included in a flight task of the aerial vehicle.
S206: if a flight path in the target flight region is included in a flight task of the aerial vehicle, modifying and updating the determined flight-limiting parameter candidate according to the meteorological information to cause the aerial vehicle to fly normally.
In some embodiments, after the flight-limiting parameter candidate is determined in S203, if the aerial vehicle is performing an automatic flight task, it is judged whether a flight path in the target flight region is included in the flight task of the aerial vehicle. If the flight path in the target flight region is included in the flight task of the aerial vehicle, the flight path may be modified to avoid the target flight region, or a flight limit, such as a limit about flight altitude and the like, may be added when the aerial vehicle is in the flight region.
In some embodiments, the flight-limiting parameters of a plurality of different regions may be obtained simultaneously in S201 to S203, and each region is judged in S205 and S206 to determine whether the flight task to be performed by the aerial vehicle will be modified or not.
Accordingly, the embodiments of the present invention may determine the flight-limiting parameters rapidly based on the obtained meteorological information of the target flight region and the mapping table, create the flight-limiting indication, and prompt the user in advance and modify the flight task of the aerial vehicle, such that the unmanned aerial vehicle can perform the flight task in various regions more safely, ensuring flight safety of the aerial vehicle and meeting requirements of the user of the aerial vehicle on automatic and intelligent meteorological information.
Referring to FIG. 3, which is a flow chart of yet another flight instructing method according to embodiments of the present invention, the method according to the embodiments of the present invention may be implemented by an intelligent mobile terminal with a network function for controlling the aerial vehicle, such as a smart phone, a tablet, an intelligent wearable apparatus or the like. The method may also be implemented by a flight controller with a network communication function disposed on the aerial vehicle. Specifically, the method may include the following steps.
S301: obtaining meteorological information of a target flight region.
Specifically, S301 may comprise: using a region where an aerial vehicle currently flies in or a region designated by the user as the target flight region; based on meteorological reference information of the aerial vehicle, accessing a network and searching the meteorological information of the target flight region indicated by the meteorological reference information. The meteorological reference information may include: designated meteorological reference information or meteorological reference information generated based on a type of the aerial vehicle.
S302: running a preset simulator according to the obtained various meteorological information as simulative meteorological input parameters, to determine an impact of a simulative meteorological environment generated by the various meteorological information on a flight of a simulated aerial vehicle, and to further determine a flight-limiting parameter candidate(s) of the aerial vehicle in the target flight region.
In some embodiments, the determined flight-limiting parameter candidate may specifically comprise any one or a combination of a flight speed parameter candidate, a flight altitude parameter candidate, and a flight distance range parameter candidate.

In some embodiments, the flight-limiting indication may be displayed directly to the user of the aerial vehicle as prompting information.
S304: judging whether a flight path in the target flight region is included in a flight task of the aerial vehicle.
S305: if the flight path in the target flight region is included in a flight task of the aerial vehicle, modifying and updating the determined flight-limiting parameter candidate according to the meteorological information, to cause the aerial vehicle to fly normally.
In some embodiments, after the flight-limiting parameter candidate is determined in S302, if the aerial vehicle is performing an automatic flight task, it is judged whether a flight path in the target flight region is included in the flight task of the aerial vehicle. If the flight path in the target flight region is included in a flight task of the aerial vehicle, the flight path may be modified to avoid the target flight region, or a flight limit, such as a limit about flight altitude and the like, may be added when the aerial vehicle is in the flight region.
In some embodiments, the flight-limiting parameters of a plurality of different regions may be obtained simultaneously in S301 to S302, and each region is judged in S304 and S305, to determine whether the flight task to be performed by the aerial vehicle will be modified or not.
Accordingly, the embodiments of the present invention may determine the flight-limiting parameters more comprehensively based on the obtained meteorological information of the target flight region and the simulator, create the flight-limiting indication, and prompt the user in advance and modify the flight task of the aerial vehicle, such that the unmanned aerial vehicle can perform the flight task in various regions more safely, ensuring flight safety of the aerial vehicle and meeting requirements of the user of the aerial vehicle on automatic and intelligent meteorological information.
Referring to FIG. 4, which is a flow chart of still yet another flight instructing method according to embodiments of the present invention, the method according to the embodiments of the present invention may be implemented by an intelligent mobile terminal with a network function for controlling the aerial vehicle, such as a smart phone, a tablet, an intelligent wearable apparatus or the like. The method may also be implemented by a flight controller with a network communication function disposed on the aerial vehicle. Specifically, the method may include the following steps.
S401: obtaining meteorological information of a target flight region.
Specifically, S401 may comprise: using a region where an aerial vehicle currently flies in or a region designated by the user as the target flight region; based on meteorological reference information of the aerial vehicle, accessing a network and searching the meteorological information of the target flight region indicated by the meteorological reference information. The meteorological reference information may include: designated meteorological reference information or meteorological reference information generated based on a type of the aerial vehicle.
S402: determining a flight-limiting parameter candidate of the aerial vehicle in the target flight region according to the obtained meteorological information.
In some embodiments, S402 may specifically comprise: looking up the flight parameter associated with the obtained meteorological information according to a preset mapping relationship between the meteorological information and the flight parameters. The looked up flight parameter is determined as the flight-limiting parameter candidate of the aerial vehicle in the target flight region. Alternatively, S402 may specifically comprise: running a preset simulator according to the obtained various meteorological information as simulative meteorological input parameters, to determine an impact of a simulative meteorological environment generated by various meteorological information on a flight of a simulated aerial vehicle, and to further determine the flight-limiting parameter candidate of the aerial vehicle in the target flight region.
In some embodiments, specifically, in the preset mapping relationship between the meteorological information and the flight parameters, the mapping relationship between the meteorological information (and a level thereof) and the flight parameters is included. Looking up a flight parameter associated with the obtained meteorological information according to the preset mapping relationship between the meteorological information and flight parameters may comprise: analyzing and determining a meteorological level of the obtained meteorological information; looking up the associated flight parameter in the preset mapping relationship between the meteorological information and the flight parameters based on the meteorological information and the level thereof. The determined flight-limiting parameter candidate may comprise any one of or a combination of a flight speed parameter candidate, a flight altitude parameter candidate, and a flight distance range parameter candidate.
S403: providing the flight-limiting parameter candidate(s) to a user for selection.
Specifically, each of the determined flight-limiting parameter candidates may be displayed to the user in a form of a button to facilitate the user to click the button to select any flight-limiting parameter candidate.
S404: generating a flight-limiting instruction for controlling a limited flight of the aerial vehicle according to a selection operation on the provided flight-limiting parameter candidates.
The user may select one or more parameters which are allowed to be limited, or one or more parameters which are not allowed to be limited, by a way of clicking by a touch screen or by a mouse or the like as required.
S405: issuing the flight-limiting instruction to control the limited flight of the aerial vehicle.
The flight limit may be performed selectively according to an actual selection of the user. For example, a limit to the flight distance may be determined in a haze weather, but since the user is in a sparsely populated and spacious region, at this time the user may select not to be limited by the flight distance. Thus, the issued flight-limiting instruction does not include a control information for controlling the aerial vehicle to fly within a limited distance (a distance from the aerial vehicle to the user).
Accordingly, the embodiments of the present invention may determine the flight-limiting parameters more comprehensively based on the obtained meteorological information of the target flight region and the simulator, create the flight-limiting indication, and prompt the user in advance and modify the flight task of the aerial vehicle, such that the unmanned aerial vehicle can perform the flight task in various regions more safely, ensuring flight safety of the aerial vehicle and meeting requirements of the user of the aerial vehicle on automatic and intelligent meteorological information.
