[0032] The present application provides a flight status detection method, device, equipment and storage medium, which can timely adjust the network search frequency of electronic equipment.

[0033] In order to make the technical personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, they should all fall within the scope of protection of the present application.

[0034] It should be noted that, in this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or plural.

[0036] See also Figure 1, Figure 1 This is a schematic diagram of a scenario disclosed in the embodiment of this application. Figure 1 The schematic scene diagram shown includes an aircraft 10 , a user 20 , and an electronic device 30 .

[0037] It is found in practice that the network search frequency of the electronic device 30 of the user 20 is usually adjusted based on the flight status of the aircraft 10. In related technologies, detecting the flight status of the aircraft 10 usually means detecting whether the aircraft 10 is flying or not flying. The detection granularity is large, resulting in poor detection accuracy of the flight status. Therefore, the adjustment of the network search frequency of the existing electronic device 30 is often not timely enough.

[0038] To solve this problem, the embodiment of the present application discloses a flight status detection method, device, equipment and storage medium, which can timely adjust the network search frequency of the electronic device 30. The flight status detection method may include: performing spectrum analysis on the acceleration data of the electronic device 30 to obtain the jump of the main frequency; determining the flight status of the aircraft 10 according to the jump, the flight status is the take-off state or the landing state; adjusting the network search frequency of the electronic device 30 according to the flight status.

[0039] By implementing this method, the acceleration data of the electronic device 30 is subjected to spectrum analysis to obtain the jump of the main frequency, and then the flight state of the aircraft 10 is detected based on the jump, whether it is a take-off state or a landing state, and finally, based on the determined flight state, the network search frequency of the electronic device 30 is adjusted. Since the take-off state or the landing state is detected based on the jump of the main frequency, the detection granularity of the flight state of the aircraft 10 is refined, which is conducive to improving the detection accuracy of the flight state, and further, the adjustment of the network search frequency of the electronic device 30 can be made more timely.

[0040] The electronic device 30 in the embodiment of the present application may include a general handheld screen electronic device, such as a mobile phone, a smart phone, a portable terminal, a terminal, a personal digital assistant (PDA), a portable multimedia player (Personal Media Player, PMP) device, a laptop computer, a notebook (Note Pad), a wireless broadband (Wireless Broadband, Wibro) terminal, a tablet computer (Personal Computer, PC) and a smart PC, etc.

[0041] The electronic device 30 may also include a wearable device. A wearable device is a portable electronic device that can be worn directly on the user or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but can also realize powerful intelligent functions through software support, data interaction, and cloud server interaction, such as: computing function, positioning function, and alarm function. At the same time, they can also connect to mobile phones and various terminals. Wearable devices may include but are not limited to watches supported by the wrist (such as watches, wrists, etc.), shoes supported by the foot (such as shoes, socks or other products worn on the legs), glasses supported by the head (such as glasses, helmets, headbands, etc.), and various non-mainstream product forms such as smart clothing, school bags, crutches, accessories, etc.

[0042] The flight status detection method disclosed in the embodiment of the present application is described in detail below in conjunction with specific implementation methods.

[0043] See also Figure 2 , Figure 2 FIG. 1 is a flowchart of the flight status detection method disclosed in the embodiment of the present application. Figure 2 The flight status detection method shown may include the following steps:

[0044] 201. The electronic device performs spectrum analysis on the acceleration data of the electronic device to obtain the jump status of the main frequency.

[0045] In an embodiment of the present application, the acceleration data of the electronic device may include an acceleration modulus value, which is used to indicate the magnitude of the acceleration of the electronic device, and the acceleration modulus value may be obtained by calculating the square root of the sum of squares of acceleration components. The acceleration components may be acquired by an accelerometer of the electronic device, and the acceleration components may include horizontal acceleration components, vertical acceleration components, and depth acceleration components.

[0046] Exemplarily, the calculation formula of the acceleration modulus at any moment is:

[0047] Among them, acc norm Indicates the acceleration modulus, acc x ,acc y ,acc z They represent the horizontal acceleration component, the vertical acceleration component and the depth acceleration component respectively.

[0048] Among them, the jump of the main frequency can be used to reflect the change of the main frequency.

[0049] It is understandable that the electronic device can obtain multiple groups of acceleration module values, and perform spectrum analysis on each group of acceleration module values ​​to obtain the frequency of the main frequency corresponding to each group of acceleration module values, and based on the frequency of the main frequency corresponding to each group of acceleration module values, obtain the jump situation of the main frequency.

[0050] Optionally, the electronic device may pre-create a buffer for storing the main frequency and its frequency. When the buffer reaches an upper limit, the electronic device obtains the jump status of the main frequency based on the frequency of the main frequency in the buffer.

[0051] In some embodiments, after obtaining the acceleration modulus value, the electronic device may first filter the acceleration modulus value, and perform spectrum analysis on the filtered acceleration modulus value to obtain the jump condition of the main frequency.

[0052] It is understandable that the electronic device filters each group of acceleration module values, performs spectrum analysis on each group of filtered acceleration module values, obtains the main frequency corresponding to each group of acceleration module values, and obtains the jump of the main frequency according to the frequency of each main frequency.

[0053] Optionally, the manner in which the electronic device filters the acceleration modulus value may include, but is not limited to, at least one of the following: smoothing filtering, bandpass filtering, arithmetic square filtering, and Kalman filtering.

[0054] Optionally, the electronic device may perform spectrum analysis on the filtered acceleration modulus value through fast Fourier transform to obtain the main frequency.

[0055] It should be noted that the electronic device first filters the acceleration modulus value and then performs spectrum analysis on the filtered acceleration modulus value, which is conducive to obtaining an accurate main frequency.

[0056] 202. The electronic equipment determines the flight state of the aircraft according to the jump situation, and the flight state is a take-off state or a landing state.

[0057] The take-off state may refer to a state in which the aircraft is moving from being stationary on the ground to flying in the air, and the landing state may refer to a state in which the aircraft is gradually descending from flying in the air to the ground.

[0058] In some embodiments, the electronic device determines the flight status of the aircraft according to the jump situation, which may include:

[0059] In a case where the jump condition indicates that the main frequency jumps from the first frequency interval to the second frequency interval, determining that the aircraft is in a take-off state, wherein the frequency value of the first frequency interval is greater than the frequency value of the second frequency interval;

[0060] When the jump condition indicates that the main frequency jumps from the third frequency interval to the fourth frequency interval, it is determined that the aircraft is in a landing state, wherein the frequency value of the third frequency interval is less than the frequency value of the fourth frequency interval.

[0061] In the embodiment of the present application, the third frequency interval may be the same as the second frequency interval, and the fourth frequency interval may be the same as the first frequency interval.

[0062] Among them, the first frequency range can be obtained by counting the frequency of the main frequency in the frequency spectrum corresponding to the acceleration modulus of the electronic device during daily use, and the second frequency range can be obtained by counting the frequency of the main frequency in the frequency spectrum corresponding to the acceleration modulus of the electronic device after the aircraft engine is started.

[0063] It should be noted that when users use electronic devices in daily life, such as swinging arms when walking and small pitching movements when reading, the frequency range is in a relatively high frequency range. The frequency peak of the main signal in the spectrum graph corresponding to the acceleration modulus value of the electronic device appears around 2.3Hz, as shown below Figure 3A When a user is on an airplane, the vibration and acceleration / deceleration motion caused by the start of the airplane engine is a relatively low-frequency motion. The frequency peak of the main signal in the spectrum graph corresponding to the acceleration modulus of the electronic device appears around 0.1 Hz, as shown in Figure 1. Figure 3B As shown. Among them, Figure 3A-3B The horizontal axis represents the frequency, and the vertical axis represents the intensity of the electric quantity or voltage.

[0064] Exemplarily, the first frequency interval may be [1.5 Hz, 5 Hz], and the second frequency interval may be [0, 0.5 Hz].

[0065] 203. Electronic devices adjust their network search frequency according to flight status.

[0066] The network search frequency of the electronic device may refer to the frequency at which the electronic device searches for network signals. The higher the network search frequency, the greater the power consumption of the electronic device.

[0067] In some embodiments, the electronic device adjusts the network search frequency of the electronic device according to the flight state, which may include: when the flight state is a take-off state, the electronic device reduces the network search frequency of the electronic device.

[0068] Optionally, the electronic device reducing the network search frequency of the electronic device may include: the electronic device reducing the network search frequency of the electronic device to a first frequency. The first frequency may be a preset lower frequency, the first frequency may be 0 or a frequency close to 0, etc., which is not limited in the embodiment of the present application.

[0069] It is understandable that when the aircraft is in the take-off state, the distance between the electronic equipment and the ground base station begins to become farther, and the signal quality decreases. At this time, the electronic equipment reduces the network search frequency to reduce the electronic equipment doing useless work, which is beneficial to reducing the power consumption of the electronic equipment.

[0070] In some embodiments, the electronic device adjusts the network search frequency of the electronic device according to the flight state, which may include: when the flight state is a landing state, the electronic device increases the network search frequency of the electronic device.

[0071] Optionally, the electronic device increasing the network search frequency of the electronic device may include: the electronic device increasing the network search frequency of the electronic device to a second frequency. The second frequency may be a preset higher frequency, and the electronic device can quickly connect to the network by searching the network at the second frequency.

[0072] It is understandable that when the plane is in the landing state, the distance between the electronic equipment and the ground base station begins to get closer, and the signal quality improves. At this time, the electronic equipment increases the network search frequency, which is conducive to the electronic equipment to quickly access the network.

[0073] In the embodiment of the present application, when the flight state is the take-off state, the electronic device can also continue to detect the landing state.

[0074] The electronic device may continue to detect the landing status in such a way that, after a preset time period, the electronic device continues to perform spectrum analysis on the acceleration data of the electronic device to obtain the jump situation of the main frequency, so as to determine the flight status of the aircraft according to the jump situation.

[0075] The preset duration may be the shortest flight duration obtained by statistics. For example, the preset duration may be 1000 seconds.

[0076] It is understandable that when the flight state is the take-off state, the electronic device may not perform take-off state (landing state) detection within a preset time period, until after the preset time period, the electronic device continues to perform landing state detection, which is beneficial to reducing the amount of calculation of the electronic device.

[0077] By implementing Figure 2 The method shown performs spectrum analysis on the acceleration data of the electronic device to obtain the jump of the main frequency, and then detects whether the flight state of the aircraft is take-off or landing based on the jump, and finally adjusts the network search frequency of the electronic device based on the determined flight state. Since the take-off state or landing state is detected based on the jump of the main frequency, the detection granularity of the flight state is refined, which is conducive to improving the detection accuracy of the flight state, and thus the adjustment of the network search frequency of the electronic device can be more timely.

[0078] See also Figure 4 , Figure 4 FIG. 1 is another flowchart of the flight status detection method disclosed in the embodiment of the present application. Figure 4 The flight status detection method shown may include the following steps:

[0079] 401. The electronic device performs spectrum analysis on acceleration data of the electronic device to obtain a jump condition of a main frequency.

[0080] 402. The electronic equipment determines the flight state of the aircraft according to the jump situation, and the flight state is a take-off state or a landing state.

[0081] For a detailed description of step 401 - step 402 , please refer to the above description of step 201 - step 202 , which will not be repeated here.

[0082] 403. The electronic device determines the confidence level corresponding to the flight state by using the frequency difference between the frequency of the main frequency before the jump and the frequency of the main frequency after the jump.

[0083] Among them, the confidence level corresponding to the flight state can be used to indicate the reliability of the flight state. The greater the confidence level, the more reliable and accurate the flight state determined by the electronic device. The frequency difference can be used to indicate the jump amplitude of the main frequency. When the flight state of the aircraft is the take-off state, the frequency difference can be obtained by subtracting the frequency of the main frequency after the jump from the frequency of the main frequency before the jump. When the flight state of the aircraft is the landing state, the frequency difference can be obtained by subtracting the frequency of the main frequency before the jump from the frequency of the main frequency after the jump.

[0084] The electronic device determines the confidence corresponding to the flight state by using the frequency difference between the frequency of the main frequency before the jump and the frequency of the main frequency after the jump, which may include: the electronic device calculates the confidence corresponding to the flight state by using the frequency difference between the frequency of the main frequency before the jump and the frequency of the main frequency after the jump and the first calculation formula.

[0085] It should be noted that the first calculation formula is a formula for the frequency difference. Exemplarily, the first calculation formula may be: wherein, prob represents the confidence level corresponding to the flight status, and deltaFreq is the frequency difference.

[0086] For example, if the main frequency jumps from 1.5 Hz to 0.5 Hz, the flight state is the take-off state. If the main frequency jumps from 0.5Hz to 4Hz, the flight state is landing state,

[0087] 404. The electronic device determines whether the confidence level corresponding to the flight status is greater than or equal to a confidence level threshold.

[0088] If yes, execute step 405; if no, execute step 406-step 407.

[0089] The confidence threshold may be obtained through a large number of experiments. For example, the confidence threshold may be 60%, 65%, etc.

[0090] 405. The electronic device adjusts the network search frequency according to the flight status.

[0091] It should be noted that when the confidence level is greater than or equal to the confidence level threshold, it indicates that the reliability of the above-mentioned flight status determined by the electronic device is relatively high, and it is believed that a take-off event or a landing event has occurred. The electronic device then directly adjusts the network search frequency of the electronic device according to the flight status.

[0092] It is understandable that the electronic device can not only determine the flight status based on the jump of the main frequency, but also determine the confidence level corresponding to the flight status, and then judge whether a take-off or landing event occurs based on the confidence level, which is conducive to further improving the detection accuracy of the flight status.

[0093] 406. The electronic device obtains a heading angle change parameter.

[0094] The heading angle variation parameter in step 406 is the heading angle variation parameter actually calculated at present. When the confidence level is less than the confidence level threshold, it indicates that the reliability of the flight state determined by the electronic device is low, and it is impossible to determine whether a take-off event or a landing event occurs. The electronic device further makes a judgment based on the heading angle variation parameter.

[0095] It should be noted that when the aircraft takes off and lands, there will be corresponding changes in the heading angle. For example, when taking off, the aircraft will perform a step-by-step climb, and will make a spiral-like upward movement, at which time the heading angle will change greatly. When the aircraft lands, the aircraft will follow the principle of "five-side takeoff and landing" to move, and at this time the heading angle will also change greatly. Based on this, the heading angle change parameter can be used to further confirm the occurrence of a takeoff event or a landing event.

[0096] The heading angle refers to the angle between the north end of the meridian at the aircraft's location and the projection of the aircraft's longitudinal axis on the horizontal plane in a clockwise direction. For an illustration of the heading angle, see Figure 5 The heading angle change parameter can be used to indicate the discrete degree of the heading angle change.

[0097] Optionally, the heading angle change parameter may include but is not limited to the variance of the heading angle change, or the standard deviation of the heading angle change.

[0098] The electronic device obtains the heading angle change parameter, which may include:

[0099] The electronic device obtains multiple heading angles within a target time period;

[0100] The electronic device calculates the heading angle difference between each pair of consecutive heading angles;

[0101] The electronic device sums up all heading angle differences to obtain a total difference;

[0102] The electronic device divides the sum of the differences by the number of heading angle differences to obtain the average change;

[0103] The electronic device obtains a first calculated value corresponding to each heading angle difference by subtracting the average change amount from each heading angle difference;

[0104] The first calculated value corresponding to each heading angle difference of the electronic device is squared and then summed to obtain a second calculated value;

[0105] The electronic device divides the second calculated value by the number of heading angle difference values ​​to obtain the variance of the heading angle change.

[0106] Furthermore, the electronic device may calculate the square root of the variance of the heading angle change to obtain the standard deviation of the heading angle change.

[0107] Optionally, the heading angle at any time within the target time period can be calculated using the dual-vector attitude determination principle; wherein the dual vectors can include the earth's gravity acceleration vector measured by an accelerometer and the geomagnetic vector measured by a magnetometer, and the main principle is:

[0108] For the vector V in the electronic device coordinate system b , the reference vector V in the reference coordinate system r , the two can be transformed through the rotation matrix, that is:

[0109]

[0110] The earth's gravity acceleration vector measured by the accelerometer and the geomagnetic vector measured by the magnetometer can be expressed as and The reference vectors corresponding to these two measured quantities can be obtained through model calculation and can be considered as known quantities, which are and pass and A new vector can be constructed: Through the correspondence between these three pairs of vectors: The following rotation matrix can be obtained:

[0111]

[0112] The rotation matrix is ​​then converted into an attitude angle, which includes a heading angle.

[0113] In addition, since the value range of the heading angle is [0, 360), directly calculating the difference of the heading angle will cause a jump problem due to 0 / 360 degree crossing. Therefore, the value range of the heading angle difference can be limited to [0, 90].

[0114] 407. When the heading angle change parameter is greater than or equal to the first parameter threshold, the electronic device adjusts the network search frequency of the electronic device according to the flight status.

[0115] It should be noted that the electronic device can obtain the parameter variation range according to the heading angle variation parameter when the aircraft takes off and / or lands multiple times, and the first parameter threshold can be the lower limit value in the parameter variation range.

[0116] Among them, when the heading angle change parameter is the variance of the heading angle change, the first parameter threshold may be a first variance threshold; when the heading angle change parameter is the standard deviation of the heading angle change, the first parameter threshold may be a first standard deviation threshold.

[0117] It can be understood that before step 407, the electronic device can also determine whether the heading angle change parameter is greater than or equal to the first parameter threshold. If the heading angle change parameter is greater than or equal to the first parameter threshold, the electronic device believes that the reliability of the above-mentioned flight state determined is high, and confirms that a take-off or landing event has occurred, then the network search frequency of the electronic device is adjusted; if the heading angle change parameter is less than the first parameter threshold, the electronic device believes that the reliability of the above-mentioned flight state determined is low, and confirms that no take-off or landing event has occurred, then the network search frequency of the electronic device is not adjusted.

[0118] In some embodiments, when the heading angle change parameter is greater than or equal to the first parameter threshold, the electronic device adjusts the network search frequency of the electronic device according to the flight state, which may include:

[0119] When the heading angle change parameter is greater than or equal to the first parameter threshold, the electronic device can directly adjust the network search frequency of the electronic device according to the flight state;

[0120] or,

[0121] When the heading angle change parameter is greater than or equal to a first parameter threshold, the electronic device increases the confidence level, wherein the increased confidence level is greater than or equal to the confidence threshold; and the network search frequency of the electronic device is adjusted according to the flight status.

[0122] It is understandable that when the heading angle change parameter is greater than or equal to the first parameter threshold, the electronic device directly adjusts the network search frequency of the electronic device according to the flight status, which is conducive to improving the flexibility of the algorithm. When the heading angle change parameter is greater than or equal to the first parameter threshold, the electronic device can increase the confidence level to greater than the confidence level threshold to trigger the execution of adjusting the network search frequency of the electronic device according to the flight status, which is conducive to reducing the complexity of the algorithm calculation.

[0123] Optionally, the electronic device raising the confidence level may include: the electronic device raising the confidence level to a target confidence level.

[0124] For example, when the confidence threshold is 65%, the target confidence may be 65%, 70%, etc., which is not limited in the embodiments of the present application.

[0125] It can be understood that when the heading angle change parameter is greater than or equal to the first parameter threshold, the electronic device can directly increase the confidence to a target confidence that is greater than the confidence threshold. At this time, the new confidence (target confidence) is greater than the confidence threshold, and the electronic device adjusts the network search frequency of the electronic device according to the flight status.

[0126] Optionally, the electronic device raising the confidence level may include: the electronic device calculating the confidence increase amount using the heading angle change parameter, the first parameter threshold, and the second parameter threshold; and summing the above confidence level and the confidence increase amount to obtain the raised confidence level.

[0127] The second parameter threshold may be an upper limit value in the above parameter variation range, and the second parameter threshold is greater than or equal to the heading angle variation parameter. When the heading angle variation parameter is the variance of the heading angle variation, the second parameter threshold may be a second variance threshold, and when the heading angle variation parameter is the standard deviation of the heading angle variation, the second parameter threshold may be a second standard deviation threshold.

[0128] Optionally, the electronic device calculates the confidence increase using the heading angle change parameter, the first parameter threshold, and the second parameter threshold, which may include:

[0129] The electronic device subtracts the first parameter threshold from the heading angle change parameter to obtain a first difference;

[0130] The electronic device subtracts the first parameter threshold from the second parameter threshold to obtain a second difference;

[0131] Dividing the first difference by the second difference to obtain a target ratio;

[0132] The target ratio is multiplied by the specified factor to obtain the confidence increase.

[0133] When the heading angle change parameter is the standard deviation of the heading angle change, the coefficient is specified to be 0.35.

[0134] Exemplarily, the calculation formula for the confidence increase may be: Among them, std_in represents the standard deviation of the current actual heading angle change, std_min represents the first standard deviation threshold, and std_max represents the second standard deviation threshold.

[0135] Furthermore, the calculation formula for the increased confidence level is:

[0136] It can be understood that when the heading angle change parameter is greater than or equal to the first parameter threshold, the electronic device can calculate the confidence increase based on the heading angle change parameter, the first parameter threshold and the second parameter threshold, which is conducive to improving the calculation accuracy of the confidence.

[0137] In some embodiments, the electronic device adjusts the network search frequency of the electronic device according to the flight status, which may include: the electronic device adjusts the network search frequency according to the flight status and the confidence level corresponding to the flight status.

[0138] It is understandable that the flight state can be used to determine the adjustment direction (reduction or increase) of the network search frequency. For example, when the flight state is the take-off state, the adjustment direction of the network search frequency is reduction; for another example, when the flight state is the landing state, the adjustment direction of the network search frequency is increase. The confidence level can be used to determine the adjustment range of the network search frequency. The higher the confidence level, the larger the corresponding adjustment range.

[0139] Based on this, the electronic device may adjust the network search frequency according to the flight status and the corresponding confidence level, including:

[0140] When the flight state is the take-off state, the electronic device determines the frequency drop amplitude according to the confidence level corresponding to the flight state; the electronic device obtains the current network search frequency of the terminal device by subtracting the frequency drop amplitude from the network search frequency of the electronic device at the previous moment;

[0141] When the flight state is a descending state, the frequency increase amplitude is determined according to the confidence level corresponding to the flight state; the electronic device uses the network search frequency of the electronic device at the previous moment plus the frequency increase amplitude to obtain the current network search frequency of the terminal device.

[0142] It should be noted that the electronic device adjusts the network search frequency based on the flight status and the corresponding confidence level, which can make the adjustment of the network search frequency more flexible.

[0143] In some embodiments, when the flight state is the take-off state and the confidence corresponding to the take-off state is greater than the confidence threshold, the electronic device continues to perform spectral analysis on the acceleration data of the electronic device after a preset time to obtain the jump situation of the main frequency to determine the flight state of the aircraft based on the jump situation.

[0144] The preset duration may be the shortest flight duration obtained by statistics.

[0145] It is understandable that when the flight state is the take-off state and the reliability of the take-off state is relatively high, the electronic device may not perform take-off state (landing state) detection within a preset time period, and continue to perform take-off state detection after the preset time period, which is beneficial to reducing the amount of calculation of the electronic device.

[0146] Based on the above embodiments, the electronic device uses two low-power sensors, an accelerometer and a magnetometer, when detecting a takeoff event or a landing event. Both sensors do not need to receive external signals and do not radiate signals to the outside, which is beneficial to reducing the power consumption of the electronic device.

[0147] Optionally, the process of electronic equipment detecting takeoff events and landing events can be found in Figure 6 ,like Figure 6 The method shown may include the following steps:

[0148] 601. The electronic device performs smoothing filtering on the acceleration modulus value.

[0149] 602. The electronic device analyzes the filtered acceleration modulus value spectrum to obtain a main frequency, and records the main frequency and its corresponding frequency in a buffer.

[0150] 603. The electronic device determines whether the buffer has reached an upper limit.

[0151] If yes, continue to execute step 604; if no, return to execute step 601.

[0152] 604. The electronic device obtains the jump status of the main frequency in the buffer.

[0153] 605. When the jump condition indicates that the main frequency jumps from the first frequency interval to the second frequency interval, the electronic device determines that the aircraft is in a take-off state.

[0154] 606. The electronic device determines the confidence level corresponding to the take-off state by using the frequency difference between the frequency of the main frequency before the jump and the frequency of the main frequency after the jump.

[0155] 607. The electronic device determines whether the confidence level is greater than or equal to a confidence level threshold.

[0156] If yes, execute step 609 - step 610 ; if no, execute step 608 .

[0157] 608. The electronic device determines whether the heading angle change parameter is greater than or equal to a first parameter threshold.

[0158] If yes, continue to execute step 609 - step 610 ; if no, continue to execute step 601 .

[0159] 609. The electronic equipment determined that a takeoff event had occurred.

[0160] 610. Setting a timer and preset duration for an electronic device.

[0161] It should be noted that after step 610, the electronic device continues to execute step 611 to detect the landing event.

[0162] 611. The electronic device determines whether it is within a preset time period.

[0163] If not, continue to execute step 601 - step 602 ; if so, continue to execute step 611 .

[0164] 612. When the jump condition indicates that the main frequency jumps from the third frequency interval to the fourth frequency interval, the electronic device determines that the aircraft is in a landing state.

[0165] 613. The electronic device determines the confidence level corresponding to the landing state by using the frequency difference between the frequency of the main frequency before the jump and the frequency of the main frequency after the jump.

[0166] 614. The electronic device determines whether the confidence level is greater than or equal to a confidence level threshold.

[0167] If yes, execute step 616 , if no, continue to execute step 615 .

[0168] 615. The electronic device determines whether the heading angle change parameter is greater than or equal to a first parameter threshold.

[0169] If yes, continue to execute step 613, if no, continue to execute step 601.

[0170] 616. Electronic equipment determined that a landing event had occurred.

[0171] By implementing Figure 4In the method shown, the electronic device first performs spectrum analysis on the acceleration data of the electronic device to obtain the jump of the main frequency, and determines the flight state of the aircraft and its corresponding confidence based on the jump, and when the confidence is high, adjusts the network search frequency of the electronic device based on the flight state, and when the confidence is low, further judges the credibility of the flight state based on the heading angle change, which is conducive to improving the detection accuracy of the flight state. Furthermore, since the electronic device detects the take-off state or the landing state based on the jump of the main frequency, the detection granularity of the flight state is refined, which can make the adjustment of the network search frequency of the electronic device more timely.
