However, this method is limited by cost, has limited training routes, requires specific locations, and cannot allow pilots to train anytime, anywhere, thus increasing the time cost of training to some extent. Summary of the Invention

[0012] Pilots can select the appropriate training curve based on the training objectives, and can set straight lines, circular arcs, and comprehensive training routes.

[0013] Set the corresponding curve parameters. For a straight line, you need to set the starting takeoff direction, flight distance, and ending altitude; for a circular arc, you need to set the starting takeoff direction, flight radius, arc angle, and center height above the ground; for comprehensive training, you only need to set the starting flight direction.

[0093] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0094] Understandably, the mainstream field route training method is limited by its single training venue, and the training routes available to pilots are also very limited. If one wants to add training routes to the traditional training method, it would require a large investment in the construction of venues, and it would also be impossible to meet the pilots' requirements for training anytime and anywhere.

[0095] To address the aforementioned issues, this invention provides an embodiment that sets a corresponding flight route based on the pilot's training objectives and records it completely. During flight training, various data from the flight backpack are acquired, including real-time positioning data, real-time speed and direction, and the flight backpack's real-time altitude. Based on the acquired real-time data, a real-time flight trajectory of the flight backpack is generated and compared with the flight backpack's set trajectory to analyze its deviation status. Based on the flight backpack's real-time trajectory deviation status and the original set route, a correction signal is output to the pilot.

[0096] Figure 1 A flowchart of the flight backpack training system provided in an embodiment of the present invention is shown.

[0097] Specifically, an auxiliary system and training method suitable for flight backpack training includes the following steps:

[0098] Step S101: Based on the training objectives set by the pilot, set the corresponding flight route and record it completely.

[0099] In this invention, when a pilot has a specific training objective, a flight route corresponding to that objective can be set. The settable routes specifically include straight training routes, circular training routes, and combined training routes. The process for setting a straight route includes setting the training starting point, the starting takeoff direction, the training distance, and the training endpoint altitude, such as... Figure 10 The process for setting up a circular route includes setting the training starting point, the takeoff direction, the altitude of the center of the training route above the ground, and the angles along the route. Figure 11 For comprehensive training routes, it is only necessary to determine the flight start point, such as... Figure 12 ,like Figure 13 After setting all the parameters, the system will automatically generate and record the training route.

[0100] In a preferred embodiment of the present invention, the step of setting a corresponding flight route based on the training objectives set by the pilot and recording it completely includes the following steps:

[0101] Step S1011: The pilot sets the starting point of the training route based on the actual scenario;

[0102] Step S1012: The pilot selects the corresponding training curve according to the training objective, which can be set as a straight line, a circular arc, or a comprehensive training route.

[0103] Step S1013: Set the corresponding curve parameters;

[0104] Step S1014: Generate and record the set curve route based on the pilot's set curve parameters.

[0105] Furthermore, the flight backpack-assisted training system also includes the following steps:

[0106] Step S102: Acquire various data of the flight backpack during flight training, including real-time positioning data, real-time speed and direction, and real-time altitude of the flight backpack.

[0107] In this invention, the system can obtain the real-time location information of the flight backpack through basic locators and other devices, generate the real-time trajectory of the flight backpack during training based on the real-time location data, and record it; at the same time, the system can measure and record the real-time speed and acceleration of the flight backpack based on the real-time changing location information.

[0108] In a preferred embodiment of the present invention, acquiring various data of the flight backpack during flight training, including real-time positioning data, real-time speed and direction, and the real-time altitude of the flight backpack, specifically includes the following steps:

[0109] Step S1021: Obtain and record real-time location information based on the locator;

[0110] Step S1022: Generate and record the corresponding flight trajectory based on real-time positioning data;

[0111] Step S1023: Measure and record the real-time speed and acceleration of the flight backpack based on the location information.

[0112] In step S1023, the step of determining and recording the real-time speed and acceleration of the flight backpack based on the location information, the function expression corresponding to the measured real-time speed is:

[0113]

[0114]

[0115] A spatial rectangular coordinate system is established with the starting point of the flight backpack route as the origin. This represents the i-th velocity vector data during the training of the flight backpack. This represents the (i+1)th displacement vector data during the training of the flight backpack. This represents the i-th displacement vector data during the training of the flight backpack. This represents the data at time i+1 during the training of the flight backpack. This represents the data at time i during the training of the flight backpack. This represents the i-th acceleration vector data during the training of the flight backpack. It's important to note that under normal training conditions, the flight backpack's real-time position is acquired synchronously with the time-series data; the first position vector is obtained from the starting position. and time data It acquires data at a frequency of once per second.

[0116] Furthermore, the flight backpack-assisted training system also includes the following steps:

[0117] Step S103: Generate the real-time flight trajectory of the flight backpack based on the obtained real-time data, and compare it with the flight backpack's set trajectory to analyze its deviation status.

[0118] In this invention, the offset state analysis and determination includes a comparative analysis of the real-time position of the flight backpack and the preset training route, and a comparative analysis of the real-time flight speed direction measured by the flight backpack and the tangent direction of the corresponding position point of the preset training route.

[0119] In a preferred embodiment of the present invention, the step of generating a real-time flight trajectory of the flight backpack based on the obtained real-time data and comparing it with the set flight backpack trajectory to analyze its deviation status specifically includes the following steps:

[0120] Step S1031: Compare the acquired real-time location information with the preset route, calculate the degree of trajectory deviation, and record it in real time;

[0121] In step S1031, the obtained real-time location information is compared with the preset route, and the function expression corresponding to the trajectory deviation is calculated as follows:

[0122]

[0123] in Indicates the degree of trajectory deviation. This represents the i-th displacement vector data during the training of the flight backpack. This represents the displacement vector data of the corresponding position point on the preset route corresponding to the i-th displacement vector data during flight backpack training. d represents the maximum distance between the real-time position of the flight backpack and the corresponding position point on the preset route under normal training conditions. It should be noted that the value of d can be manually set by the pilot; if not manually set, 2.5 is selected as the default value.

[0124] Step S1032: Compare the obtained real-time flight direction with the tangent of the corresponding point on the preset route, calculate the offset angle and record it in real time;

[0125] In step S1032, the obtained real-time flight direction is compared with the tangent at the corresponding point on the preset route, and the function expression corresponding to the offset angle is calculated as follows:

[0126]

[0127] in Indicates the degree of angular offset. This represents the i-th velocity vector data during the training of the flight backpack. This represents the unit vector along the tangent direction of the position point on the preset route corresponding to the i-th displacement vector data during flight backpack training. It is a radian measure of angles.

[0128] Step S1033: Combine trajectory offset and direction offset to perform data analysis, and then determine its offset status.

[0129] In step S1033, data analysis is performed by combining trajectory offset and direction offset to determine the function expression corresponding to its offset state:

[0130]

[0131] in This is the offset state determination value. It's important to note that when... When the flight status of the flight backpack is determined to be normal, it is considered to be normal. If the training status of the flight backpack is abnormal at that time, it will be determined that the training status is abnormal. This represents the i-th velocity vector data during flight backpack training. t represents the preset time, which the pilot can set. Under the same conditions as other parameters in flight backpack training, the larger this value, the higher the likelihood that the system will determine it as an abnormal training state. The default value of 1 is used if the pilot does not set it. d represents the maximum distance between the flight backpack's real-time position and the corresponding point on the preset route under normal training conditions. It should be noted that the value of d can be manually set by the pilot; if not manually set, 2.5 is selected as the default value. Indicates the degree of trajectory deviation. Indicates the degree of angular deviation.

[0132] Furthermore, the flight backpack-assisted training system also includes the following steps:

[0133] Step S104: Based on the real-time trajectory deviation of the flight pack and the original set route, output a correction signal to the pilot.

[0134] In this embodiment of the invention, when the offset determination result indicates a normal training state, the system will use a locator to re-acquire the real-time position of the flight backpack to ensure the accuracy of subsequent route correction design; in order to output signal lights according to the corrected route plan, signal lights are equipped on the flight backpack, such as... Figure 14 The four directional indicator lights provide route correction instructions for the four directions: up, down, left, and right. It's important to note that two of these lights can be on simultaneously, or a single indicator light can illuminate. For example, if the up and left indicator lights are on simultaneously, it means the pilot of the jetpack needs to fly to the upper left to return to the preset training route.

[0135] In a preferred embodiment of the present invention, the step of outputting a correction signal to the pilot based on the real-time trajectory deviation of the flight backpack and the original planned route specifically includes the following steps:

[0136] Step S1041: Receive the offset state determination result, indicating that it is in a normal training state;

[0137] Step S1042: Further analyze the deviation between the real-time location and the set route, and design a corrected route plan;

[0138] In step S1042, the function expression for further analyzing the deviation between the real-time location point and the set route, and designing the corrected route scheme, is as follows:

[0139]

[0140] in, This represents the variable controlling the left and right directions of the output correction path. This represents the z-coordinate of the vector within the parentheses. This is represented by the degree of trajectory offset when the z-coordinate is 0. The velocity vector data where the i-th z-coordinate is zero during flight backpack training. This represents the variable that controls the vertical direction of the corrected path output by the controller. This indicates the degree of trajectory deviation. It's important to note that when the Y value is positive, the output is a corrected path to the left; when the Y value is negative, the output is a corrected path to the right. When the Z value is positive, the output is a corrected path to the up; when the Z value is negative, the output is a corrected path to the down.

[0141] Step S1043: Based on the revised route plan, output instructions to the signal lights to assist the pilot in correcting the direction;

[0142] In step S1043, when a corrected route is output to the left, the left indicator light will illuminate; when a corrected route is output to the right, the right indicator light will illuminate. When a corrected route is output to the up, the forward indicator light will illuminate; when a corrected route is output to the down, the rear indicator light will illuminate.

[0143] Furthermore, Figure 8 The application architecture diagram of the flight backpack-assisted training system provided in this embodiment of the invention is shown.

[0144] In another preferred embodiment of the present invention, an auxiliary system suitable for flight backpack training includes:

[0145] The training route setting unit 101 is used to set a specific training route based on the pilot's specific training objectives, and to acquire and record the route setting information.

[0146] In this invention embodiment, when a pilot has a relatively specific training objective, the training route setting unit 101 can set a flight route corresponding to that training objective. The settable routes specifically include straight training routes, circular training routes, and comprehensive training routes. The setting process for a straight route includes setting the training starting point, the starting point takeoff direction, the training distance, and the training endpoint altitude, such as... Figure 10 The process for setting up a circular route includes setting the training starting point, the takeoff direction, the altitude of the center of the training route above the ground, and the angles along the route. Figure 11 For comprehensive training routes, it is only necessary to determine the flight start point, such as... Figure 12 ,like Figure 13 After setting all the parameters, the system will automatically generate and record the training route.

[0161] Furthermore, the flight backpack-assisted training system also includes:

[0162] The offset state analysis unit 103 is used to compare and analyze the trajectory during flight training with the set route, and at the same time, analyze the overall offset data of the flight backpack by combining the angle deviation between the real-time flight direction and the tangent direction of the set route.

[0170] The flight suggestion output unit 104 is used to determine the offset status of the flight backpack based on the overall offset data of the flight backpack. If it is determined to be normal, it generates a corrected route suggestion and outputs it to the pilot.

[0171] In this embodiment of the invention, when the flight suggestion output unit 104 receives a deviation determination result indicating a normal training state, the system will use a locator to re-acquire the real-time position of the flight backpack to ensure the accuracy of subsequent route correction design. To output signal lights based on the corrected route plan, signal lights are equipped on the flight backpack, such as... Figure 14 The four directional indicator lights provide route correction instructions for the four directions: up, down, left, and right. It's important to note that two of these lights can be on simultaneously, or a single indicator light can illuminate. For example, if the up and left indicator lights are on simultaneously, it means the pilot of the jetpack needs to fly to the upper left to return to the preset training route.

[0172] Specifically, Figure 6 A structural block diagram of the flight suggestion output unit 104 in the system provided by an embodiment of the present invention is shown.

[0173] In a preferred embodiment of the present invention, the flight suggestion output unit 104 specifically includes:

[0176] Signal output module 1043 converts the corrected route plan into indicator light signals and outputs them to the pilot;

[0177] Understandably, to ensure the safety of pilots during training, the auxiliary system is equipped with a safety braking system. This system can be triggered by the pilot pressing a button, or it can be triggered by the system detecting deviation and alerting the pilot after detecting abnormal training conditions.
