[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] Example 1

[0063] Please see Figure 1 . Figure 1 This is a flowchart illustrating a collaborative search and rescue method for personnel in a search and rescue aircraft, as disclosed in an embodiment of the present invention. Figure 1 The described search and rescue aircraft personnel collaborative search and rescue method is applied in a management system, such as a local server or cloud server for management, and the embodiments of the present invention are not limited thereto.

[0064] like Figure 1 As shown, the collaborative search and rescue method for personnel in a search and rescue aircraft disclosed in this embodiment of the invention includes:

[0065] S1. Obtain search target information and search and rescue resource information; the search target information includes the location coordinates of the search target, sea state information, terrain type, wind information, weather conditions, number of targets and injury level, etc.; the search and rescue resource information includes the location, flight status and search progress of search and rescue aircraft, as well as the location and rescue capabilities of ground rescue personnel, etc.

[0066] S2. Process the search target information and the search and rescue resource information to obtain a search and rescue plan;

[0067] S3. Evaluate and process the search and rescue plan to obtain the final search and rescue plan.

[0068] In another optional embodiment, the processing of the search target information and the search and rescue resource information to obtain a search and rescue plan includes:

[0069] S21. Match the search target information and the search and rescue resource information to obtain rescue information; the rescue information includes search range information and rescue equipment information.

[0070] S22. Based on the rescue information, the search target information and the search and rescue resource information are processed to obtain a search and rescue plan; the search and rescue plan includes a search path and a rescue mode, wherein the rescue mode is water rescue and / or airdrop rescue.

[0071] In another optional embodiment, the step of using a target-resource matching model to match the search target information and the search and rescue resource information to obtain rescue information includes:

[0072] S211. The search target information is processed to obtain search range information; the search range information includes the search target base point position and the search radius; the search range information represents a circle with the search target base point position as the center and the search radius as the radius.

[0073] Based on the search target information, the search base point correction model is used to process the data to obtain the search target base point position.

[0074] The search base point correction model is expressed as follows:

[0075] D = (x0 + Δx, y0 + Δy, z0)

[0076]

[0077] In the formula, D represents the corrected position of the search target base point, x0, y0, z0 represent the horizontal, vertical, and depth coordinates of the search target in the search target information; Δx and Δy represent the correction values ​​for the horizontal and vertical coordinates, respectively; v w vs These represent wind speed and ocean current speed, respectively; φ w , φ s These represent the wind direction angle and the ocean current direction angle, respectively; t d Indicates the time when the search and rescue aircraft arrived at the search location;

[0078] Based on the location of the target base point, the search radius is calculated using a search radius calculation model; the search radius calculation model is expressed as follows:

[0079]

[0080] In the formula, T represents the time interval from the time of distress to the start of the search; c w c represents the wind-induced drift coefficient. w The value ranges from 0.02 to 0.05, and is adjusted according to wind speed and target type;

[0081] S212. Based on the search range information, the search and rescue resource information is configured to obtain rescue equipment information; the rescue equipment information represents the equipment information participating in the rescue; the rescue equipment information includes search equipment requirements, rescue equipment requirements, medical equipment requirements, and communication equipment requirements, etc.

[0082] It should be noted that the technical solution described in the above embodiments takes into account the initial position of the search target, as well as multiple factors such as wind speed and ocean current speed. It can more accurately predict the drift position of the target under the influence of various environmental factors, improve the accuracy of the base point position, and thus provide a more reliable starting point for subsequent search work.

[0083] In another optional embodiment, the step of configuring the search and rescue resource information based on the search range information to obtain rescue equipment information includes:

[0084] S2121. The required configuration of search equipment shall be determined based on the search radius and marine environment.

[0085] When the search radius is small (e.g., less than 50 nautical miles) and the visibility in the sea area is good, equipment such as radar and optical telescopes should be deployed. Radar can quickly scan and locate targets within a certain range, while optical telescopes can conduct detailed observation and identification of targets at close range.

[0086] When the search radius exceeds 50 nautical miles, or when the marine environment is complex (such as low visibility weather such as heavy fog or heavy rain), more advanced search radar and infrared detection equipment are required to effectively search for distant targets in adverse environments.

[0087] S2122. The configuration of rescue equipment should be centered on the goal of rapid and safe rescue, mainly including lifeboats, hoisting equipment and diving equipment, which can cope with complex maritime rescue situations.

[0088] S2123. Medical equipment requirements must meet the needs of emergency treatment for those in distress during rescue operations, including first-aid kits containing tourniquets, bandages, oxygen cylinders, and CPR equipment to address common injuries and sudden illnesses. For missions with large search radii and potentially long rescue times, portable medical diagnostic equipment, such as electrocardiographs, blood pressure monitors, and blood glucose meters, is also required to enable medical personnel to conduct preliminary diagnoses and monitoring of the distressed individuals' conditions.

[0089] S2124. The configuration of communication equipment must ensure that all rescue forces can communicate in real time and stably with the command center.

[0090] All search and rescue aircraft involved in the rescue operation should be equipped with VHF communication equipment for short-range real-time communication to facilitate coordination of rescue operations. For long-range communication, satellite phones and satellite communication equipment are required to ensure contact with the command center in areas without ground communication signals, enabling timely reporting of search and rescue progress and requests for support. In addition, emergency communication equipment, such as emergency beacons and radio position indicators, should be deployed to send distress signals in case of equipment malfunction or distress, thereby improving the aircraft's own safety.

[0091] In another optional embodiment, the step of processing the search target information and the search and rescue resource information based on the rescue information to obtain a search and rescue plan includes:

[0092] S221. Determine the search path based on the search range information;

[0093] S222. Determine the rescue mode based on the search range information and the rescue equipment information.

[0094] In yet another optional embodiment, determining the search path based on the search range information includes:

[0095] S2211. Calculate the forward distance based on the search base point; the forward distance represents the distance the search and rescue aircraft travels from its current position to the search base point.

[0096] S2212. Determine whether the forward distance is less than the first distance, and obtain the first determination result;

[0097] If the first judgment result is yes, proceed to step S2213; otherwise, proceed to step S2214.

[0098] S2213. Determine whether the search radius is less than the second distance, and obtain the second judgment result;

[0099] If the second determination result is yes, the first search route is adopted; otherwise, the second search route is adopted.

[0100] The first search route is as follows: taking the search base point as the starting point of the search area, the search and rescue aircraft enters the search area, constructs an equilateral triangle track with the search base point as the base point, and uses the side length of the equilateral triangle as the search radius. After completing one equilateral triangle track search, the search and rescue aircraft turns 120° to the right to perform the next equilateral triangle track search. If the search target is not found after the first search, the entire search segment can be rotated 30° clockwise to perform the next round of search.

[0101] The second search route is as follows: the interval of the search lines is determined based on the performance of the search sensors, with 80% of the detection distance of the search sensors used as the interval. The search base point is used as the starting point of the search area. The search and rescue aircraft enters the search area, and the length of the first segment is the interval of the search lines. It then turns 90° to the right, and the length of the second segment plus the interval of the search lines forms the third segment. It turns 90° to the right again, and the length of the third segment forms the fourth segment, and so on. For every two segments of search length, the distance between the search lines is increased by one, and then the search expands outwards in concentric rectangles. After completing the first round of expanded square search, if further searching is needed, the entire search segment can be rotated 45° for the next round of search.

[0102] S2214. Determine whether any vessels are cooperating in the search, and obtain the third judgment result;

[0103] If the third judgment result is yes, the third search route is adopted; otherwise, the fourth search route is adopted.

[0104] The third search route is as follows: with the search base point as the center, a rectangular search area covering the search radius is constructed, the search line spacing is determined, the search starting point is located within the rectangular search area at a distance of 1 / 2 search line spacing from each of the two right-angled sides, the search line spacing is not greater than the detection distance of the search sensor, the search line spacing is the scanning width, and then the search is performed back and forth along the short side of the rectangle while maintaining the spacing.

[0105] The fourth search route is as follows: with the search base point as the center, a rectangular search area covering the search radius is constructed, the search line spacing is determined, the search starting point is located within the rectangular search area at a distance of 1 / 2 search line spacing from each of the two right-angled sides, the search line spacing is not greater than the detection distance of the search sensor, the search line spacing is the scanning width, and then the search is performed back and forth along the long side of the rectangle while maintaining the spacing.

[0106] It should be noted that the technical solutions described in the above embodiments adapt to different scenario requirements by designing flexible and diverse search routes.

[0107] In yet another optional embodiment, determining the rescue mode based on the search range information and the rescue equipment information includes:

[0108] Based on the weather conditions in the search target information, wind force, wind speed, and sea state are processed to obtain search and rescue hazard values. It should be noted that by quantifying weather and sea state parameters, combined with preset weight allocation and risk matrix, wind force, wind speed, and sea state are transformed into quantifiable search and rescue hazard values.

[0109] Based on the rescue equipment information, it is determined whether the search and rescue danger value exceeds the safety threshold of the search and rescue aircraft, and a fourth judgment result is obtained;

[0110] If the fourth judgment result is yes, the airdrop rescue is adopted as the target rescue mode; otherwise, the water rescue is adopted as the target rescue mode.

[0111] If the rescue involves water landing, a rescue area is set up based on the extent of the distress, and the k-means clustering method is used to calculate the water landing point of the search and rescue aircraft before carrying out the rescue. If the rescue involves airdrop, environmental parameters are read or can be readjusted, and the airdrop location of the search and rescue aircraft is calculated based on wind force, wind direction, wind speed, etc. before carrying out the airdrop rescue.

[0112] It should be noted that a reasonable water-receiving area is calculated based on the target's location to achieve a safe and rapid rescue effect;

[0113] In the aforementioned airdrop rescue, based on the target location and the sea conditions at the time, including wave height, wind speed, and wind direction, a suitable airdrop location and direction are calculated to ensure that the airdropped rescue supplies are scattered in an accessible location within the target area, thus ensuring the effectiveness of the rescue.

[0114] It should be noted that the technical solutions described in the above embodiments can quickly and accurately determine the rescue mode according to different environmental conditions, improve the success rate and efficiency of search and rescue operations, and provide more reliable and effective rescue protection for people in distress.

[0115] In another optional embodiment, the step of processing wind force, wind speed, and sea state based on weather conditions in the search target information to obtain a search and rescue danger value includes:

[0116] According to industry standards, wind force, wind speed, and sea state parameters are converted into a risk score of 1-5 points. The higher the score, the higher the risk.

[0117] Based on the actual impact of each parameter in the search and rescue scenario, the weights of wind force (W1), wind speed (W2), and sea state (W3) are preset to satisfy W1+W2+W3=1;

[0118] The total risk score (S) is obtained by multiplying the scores of each quantified parameter by their corresponding weights and summing the results.

[0119] The specific calculation formula is as follows:

[0120] S = P w *W1+P v *W2+P s *W3

[0121] In the formula, S represents the total risk score; P w Indicates wind force rating; P v Indicates wind speed rating; P s The values ​​represent the sea state score; W1, W2, and W3 represent the weights of wind force, wind speed, and sea state, respectively.

[0122] In yet another optional embodiment, the evaluation of the search and rescue plan to obtain the final search and rescue plan includes:

[0123] S31. According to the search and rescue plan, the search target information and the rescue information are processed using a discovery probability model to obtain a discovery probability estimate;

[0124] The discovery probability model is expressed as follows:

[0125]

[0126] In the formula, P represents the estimated probability of discovery, k represents the matching coefficient, which is related to the search route and search mode and is preset according to the expert system; λ represents the detection sensitivity parameter of the search and rescue aircraft; A represents the search range, and T S Indicates search duration; ξ represents weather influence factor; μ represents sea state influence factor; V P Indicates the speed of the search and rescue aircraft; H indicates the spacing between search lines;

[0127] The weather influence factor ξ is represented as follows:

[0128] ξ=exp(-k w v w -k r p r -k v l v )

[0129] In the formula, k w v w These represent the wind speed influence coefficient and wind speed, respectively, k. w=0.02; k r p r k represents the rainfall impact coefficient and rainfall intensity, respectively. r =0.4; k v l v Representing the visibility distance influence coefficient and visibility distance (in meters), respectively, k v =0.01;

[0130] The sea state influence factor μ is expressed as:

[0131] μ = exp(-k h w h -k s v s -k si v si )

[0132] In the formula, k h w h Representing the wave height influence coefficient and wave height respectively, k h =0.3; k s v s Representing the influence coefficient of ocean current velocity and ocean current velocity, respectively, k s =0.04; k si v si Let k represent the seawater visibility influence coefficient and seawater visibility, respectively. si =0.06;

[0133] The recommended range for the matching coefficient is 0.6 to 0.9, specifically:

[0134] When the search line and search mode are highly matched with the target characteristics and environment, such as using parallel dense search lines and radar mode for static targets at known locations, the matching coefficient can be taken as 0.8 to 0.9.

[0135] When the matching degree is average, such as when using conventional fan-shaped search lines and visual mode for dynamic targets, the matching coefficient can be taken as 0.7 to 0.8;

[0136] When the matching degree is low, such as when using a coarse search route and a single visual mode for unknown dynamic targets, the matching coefficient can be taken as 0.6 to 0.7.

[0137] It should be noted that traditional search and rescue plan selection may rely on experience-based judgment, which is highly subjective. The technical solution provided in this application uses the probability of discovery as the criterion, which can eliminate reliance on mere experience and reduce the interference of human factors in decision-making. Judging the merits of a plan based on the probability of discovery ensures that search and rescue decisions are always focused on improving the likelihood of target discovery, ensuring that resource allocation and action deployment are directed in the direction most conducive to target discovery, avoiding the waste of resources on plans that lack efficient target discovery capabilities, and maximizing the achievement of search and rescue operation objectives.

[0138] S32. Determine whether the estimated discovery probability is less than the preset expected value, and obtain the fifth determination result;

[0139] When the fifth judgment result is yes, after optimizing the search and rescue plan by adjusting parameters such as search range, search route, search mode, search time, and search equipment, step S31 is executed to recalculate the estimated probability of discovery.

[0140] If the fifth judgment result is negative, the search and rescue plan will be determined as the final search and rescue plan.

[0141] As can be seen, the technical solution described in the above embodiments, based on the dynamic assessment of the discovery probability, provides strong support for the flexible adjustment of the search and rescue plan. When the discovery probability does not meet the expected value, it can quickly optimize the factors affecting the discovery probability (such as search routes, search modes, search time, etc.), recalculate the discovery probability, and continue until the plan achieves the best results. This dynamic optimization mechanism enables search and rescue operations to quickly adapt to complex and ever-changing environments, improving the ability to respond to emergencies.
