[0002] Aircraft often lose control due to various reasons. For example, existing aircraft products rely on wireless communication to control flight, or rely on satellite positioning system to fly autonomously, but wireless communication or satellite positioning system are very susceptible to interference in certain places. Moreover, the existing aircraft generally do not have the anti-collision function. When the aircraft collides with power lines, or collides with trees, it will cause the aircraft to lose control.
For another example, sometimes the aircraft flies far away, beyond the operator's line of sight, if the control is not proper, the aircraft may lose control

[0160] see Figure 4 , the method can include:
[0161] Step 400, the mobile terminal detects that the communication with the aircraft fails, and obtains the state parameter information sent last time by the aircraft before the communication fails.
[0162] In this step, the state parameter information includes altitude information, speed information, first position information and remaining power information of the aircraft.
[0163] Step 401 , the mobile terminal judges whether the remaining power is less than or equal to a preset threshold, if yes, execute steps 402 to 404 ; if not, execute steps 405 to 408 .
[0164] Step 402, the mobile terminal determines first distance information according to the altitude information and speed information.
[0165] Step 403, the mobile terminal determines the second location information of the aircraft according to the first distance information and the first location information.
[0166] In this step, the second position informati...

[0175] Step 500, the mobile terminal detects that the communication with the aircraft fails, and obtains the status parameter information sent by the aircraft last time before the communication fails.
[0176] In this step, the state parameter information includes altitude information, speed information, first position information and remaining power information of the aircraft.
[0177] Step 501 , the mobile terminal judges whether the remaining power is less than or equal to a preset threshold, if yes, execute steps 502 to 504 ; if not, execute steps 505 to 508 .
[0178] Step 502, the mobile terminal determines first distance information according to the altitude information, speed information and wind speed information.
[0179] Step 503, the mobile terminal determines the second location information of the aircraft according to the first distance information and the first location information.

Abstract
The embodiment of the invention discloses an aircraft positioning method and an aircraft positioning device. The aircraft positioning method comprises the following steps: when a mobile terminal detects that communication between the mobile terminal with an aircraft fails, acquiring state parameter information which is transmitted for the last time before communication failure from the aircraft bythe mobile terminal, wherein the state parameter information comprises height information, speed information and first position information of the aircraft; according to the height information and the speed information, confirming first distance information by the mobile terminal; according to the first distance information and the first position information, confirming second position information of the aircraft, wherein the second position information is used for representing the position of a landing point of the aircraft. By adopting the scheme of the embodiment of the invention, the position of the landing point of the aircraft is accurately confirmed by the mobile terminal according to the state parameter information transmitted for the last time from the aircraft before communication failure, so that the search range of a user is reduced, and the success rate that the aircraft is found by the user is increased.
Description
technical field [0001] The invention relates to aircraft technology, in particular to an aircraft positioning method and a mobile terminal. Background technique [0002] Aircraft often lose control due to various reasons. For example, existing aircraft products rely on wireless communication to control flight, or rely on satellite positioning system to fly autonomously, but wireless communication or satellite positioning system are very susceptible to interference in certain places. Moreover, the existing aircraft generally do not have the anti-collision function. When the aircraft collides with a power line, or collides with a tree, the aircraft will lose control. For another example, sometimes when the aircraft flies farther than the operator's line of sight, if the control is not done properly, the aircraft may lose control. After the aircraft loses control, how to determine the landing position of the aircraft has become a subject of active research by those skilled in ...
