[0031] See also Figure 1 , Figure 1 is a system architecture diagram of a search and rescue system provided in an embodiment of the present application, such as Figure 1As shown, the search and rescue system 100 includes: a server 110, a beacon search and rescue device 130 and a Beidou watch 120, and the server 110 is communicatively connected with the beacon search and rescue device 130 and the Beidou watch 120 respectively.

[0032] Among them, the Beidou watch 120 is a smart watch based on the timing and positioning of the Chinese Beidou satellite navigation system. The Beidou watch 120 can receive the Beidou satellite navigation system signal for timing; and the Beidou watch 120 has a positioning function, can display longitude and latitude information, and is equipped with functions such as a compass and an altimeter. Specifically, the Beidou watch 120 may include: a processing module, a storage module, and a sending module. Among them, the processing module is used to identify the user's distress operation in a trapped and distressed situation, such as pressing a distress button or sending a distress signal through the operation interface of the Beidou watch; the storage module is used to store the user's historical distress records for subsequent analysis of the user's search and rescue related data, such as search and rescue time, search and rescue effect, etc.; the sending module is used to generate a wireless signal based on the distress signal received by the processing module to send a distress signal to the outside world.

[0033] Among them, the beacon search and rescue equipment 130 can be a satellite phone, which can communicate using communication satellites and can receive distress signals sent by search and rescue beacons in remote areas or areas without ground communication network coverage; it can also be a search and rescue handheld terminal that integrates the short message function of the Beidou system and can receive short message distress signals sent by search and rescue beacons. Specifically, it can communicate in an environment without ground communication network coverage.

[0034] See also Figure 2 , Figure 2 is a specific flow chart of a method for processing search and rescue information for avalanche events provided by an embodiment of the present application, which is applied to Figure 1 The server 110 in the search and rescue system 100 shown in FIG. Figure 2 As shown, the method comprises the following steps:

[0035] S210, receiving a distress signal from the Beidou watch.

[0036] Among them, the distress signal is associated with the distress event of the Beidou watch, and the distress signal carries the initial positioning information used to indicate the location of the Beidou watch.

[0037] Among them, the initial positioning information can only indicate the location information of the Beidou watch within a certain range. Due to factors such as being buried under snow and possible damage to signal transmission, the Beidou watch cannot be accurately located.

[0038] Specifically, a distress call event occurs when a person in distress wearing a Beidou watch presses the distress button of the Beidou watch or touches the smart panel of the Beidou watch to call for help when suddenly encountering an avalanche.

[0039] S220: Determine the area to be searched and rescued in the current avalanche event according to the initial positioning information.

[0040] The search and rescue area refers to the area covered by snow due to an avalanche event. After detecting the initial positioning information, the server determines that there are people buried in an avalanche and a search and rescue operation is required.

[0041] In one possible example, the search and rescue system also includes a drone, which carries an image sensor, and the server is communicatively connected to the drone; determining the area to be searched and rescued in the current avalanche event based on the initial positioning information, including: sending an image acquisition message to the drone, the image acquisition message is used to instruct the drone to go to the area indicated by the positioning information to collect images; receiving on-site image information of the avalanche event sent by the drone; based on the on-site image information of the avalanche event, determining a first coordinate position and a second coordinate position of the avalanche event, the first coordinate position is a starting position representing the avalanche event, and the second coordinate position is an end position representing the avalanche event; and determining the lateral coverage range of the avalanche event; determining the area to be searched and rescued based on the first coordinate position, the second coordinate position and the lateral coverage range.

[0042] Specifically, the drone uses image sensors to conduct all-round and three-dimensional reconnaissance of the avalanche area, and preliminarily determines the buried area by observing the avalanche flow path, accumulation terrain, and possible signs of trapped victims (such as clothing, equipment, etc.).

[0043] Specifically, see Figure 3 , Figure 3 is a schematic diagram of an avalanche event scenario provided by an embodiment of the present application, Figure 3 This is the on-site image information obtained by the drone in this example, such as Figure 3 As shown, the avalanche coverage area 300 includes: a first coordinate position 301 representing the coordinates of the location where the avalanche occurred, which is generally located at a higher altitude position on the snow mountain, such as the top of the mountain or the mountainside; a second coordinate position 302 representing the coordinates of the stopping position of the avalanche, which is generally located at a lower position than the first coordinate position, such as the foot of the mountain; and a lateral coverage range determined according to the image information, such as Figure 3 The coverage area formed between the third coordinate position 303 and the fourth coordinate position 304 is shown in FIG.

[0044] Among them, the coordinate position indicates the outermost coordinates of the avalanche coverage area, that is, based on the above-mentioned first position coordinate 301, second position coordinate 302, third position coordinate 303 and fourth position coordinate 304, the determined search and rescue area is the most extensive search and rescue area, including the entire avalanche coverage area.

[0045] It can be seen that in this example, by sending an image collection message to the drone, the on-site image information of the avalanche event sent by the drone is received, and based on the on-site image information of the avalanche event, the first coordinate position and the second coordinate position of the avalanche event are determined, as well as the lateral coverage range of the avalanche event are determined; and according to the first coordinate position, the second coordinate position and the lateral coverage range, the area to be searched and rescued is determined. In this way, the avalanche coverage site is accurately fed back through image information, thereby improving the accuracy and reliability of determining the search and rescue range, which is conducive to improving the success rate of the search and rescue operation.

[0046] S230: Divide the area to be searched and rescued into a plurality of sub-areas to be searched and rescued according to the detection range of the beacon search and rescue equipment and the number of search and rescue personnel.

[0047] The beacon search and rescue equipment is a device used by search and rescue personnel to receive distress beacons, and the detection range is the signal coverage range of the beacon search and rescue equipment to detect the Beidou watch beacon. The detection range is the signal range of the beacon search and rescue equipment that can receive distress signals.

[0048] In one possible example, the area to be searched and rescued is divided into multiple sub-areas to be searched and rescued according to the detection range of the beacon search and rescue equipment and the number of search and rescue personnel, including: determining a first search and rescue width according to the size of the lateral coverage range; determining a second search and rescue width according to the detection range and the number of search and rescue personnel, the second search and rescue width being used to characterize the product of the diameter of the detection range and the number of search and rescue personnel; comparing the first search and rescue width and the second search and rescue width; when the first search and rescue width is greater than the second search and rescue width, determining a first proportional relationship between the first search and rescue width and the number of rescue personnel, dividing the area to be searched and rescued into multiple sub-areas to be searched and rescued according to the first proportional relationship, and the number of sub-areas to be searched and rescued is associated with the first proportional relationship; when the first search and rescue width is less than or equal to the second search and rescue width, determining a second proportional relationship between the first search and rescue width and the detection range, dividing the area to be searched and rescued into multiple sub-areas to be searched and rescued according to the second proportional relationship, and the number of sub-areas to be searched and rescued is associated with the second proportional relationship.

[0049] When the first search and rescue width is greater than the second search and rescue width, it means that the number of people to be searched and rescued is small, and the search and rescue area needs to be divided according to the number of people, and the number of people is equal to the number of sub-areas to be searched and rescued; for details, please refer to Figure 4a , Figure 4a is a schematic diagram of a scene of a sub-area to be searched and rescued provided in an embodiment of the present application, such as Figure 4aAs shown, if the number of rescuers is 4 at this time, and the lateral coverage distance of the avalanche area 300 is greater than the diameter of the detection range of 4 people, the area to be searched and rescued is divided into 4 areas according to the number of rescuers, namely the first sub-area to be searched and rescued 4011, the second sub-area to be searched and rescued 4012, the third sub-area to be searched and rescued 4013 and the fourth sub-area to be searched and rescued 4014. The rescuers in each sub-area to be searched and rescued carry a beacon search and rescue equipment. In this way, the number of sub-areas to be searched and rescued is divided according to the number of people, which ensures the comprehensiveness of the search and rescue in the areas to be searched and rescued while ensuring the rescue effect.

[0050] When the first search width is less than or equal to the second search width, it means that there are many people to be rescued. Therefore, the search area is divided according to the diameter of the detection range to ensure that each sub-area to be searched can fully receive the search beacon. Figure 4b , Figure 4b is a schematic diagram of another scene of a sub-area to be searched and rescued provided in an embodiment of the present application, such as Figure 4b As shown, for the avalanche region 300, according to Figure 1 The detection range diameter of the beacon search and rescue device 130 is divided into: Figure 4b As shown, the area to be searched and rescued is divided into five parts, including the fifth sub-area to be searched and rescued 4021, the sixth sub-area to be searched and rescued 4022, the seventh sub-area to be searched and rescued 4023, the eighth sub-area to be searched and rescued 4024 and the ninth sub-area to be searched and rescued 4025, wherein each sub-area to be searched and rescued includes at least one search and rescue personnel, that is, at least one beacon search and rescue device 130. It should be understood that it also includes the situation as shown in the fifth sub-area to be searched and rescued 4021, including two search and rescue personnel and carrying two beacon search and rescue devices. In this way, the search and rescue area can be reasonably divided according to the rescue resources, the search and rescue efficiency can be improved, and the success rate of the search and rescue operation can be increased.

[0051] S240, determining a search and rescue path for multiple sub-areas to be searched and rescued according to the sub-areas to be searched and rescued and the detection range, to ensure that the area covered by the search and rescue personnel when searching and rescuing according to the corresponding search and rescue path includes the sub-areas to be searched and rescued.

[0052] In one possible example, based on the sub-areas to be searched and rescued and the detection range, the search and rescue paths of multiple sub-areas to be searched and rescued are determined, including: determining the width of each sub-area in the multiple sub-areas to be searched and rescued; comparing the sub-area width with the detection range; when the sub-area width is less than or equal to the detection range, determining the search and rescue path to be a straight line path, and the straight line path refers to the straight line route from the search and rescue starting point to the search and rescue end point; when the sub-area width is greater than the detection range, determining the search and rescue path to be a broken line path, and the broken line path refers to the broken line route from the search and rescue starting point to the search and rescue end point.

[0053] Among them, if according to the above judgment, when the first search and rescue width is greater than the second search and rescue width, there is a situation where the sub-area width is greater than the detection range. At this time, a zigzag path is taken so that the rescue personnel's search and rescue signal receiving range covers the entire sub-area to be searched and rescued, without missing the search and rescue coverage range, thereby ensuring the search and rescue effect; if the first search and rescue width is less than or equal to the second search and rescue width, the sub-area width is equal to the detection range. At this time, a straight line path is taken, which can satisfy the search and rescue personnel's search and rescue range to cover the sub-area to be searched and rescued.

[0054] It can be seen that in this example, by determining the width of each sub-area in multiple sub-areas to be searched and rescued, and comparing the sub-area width with the detection range, when the sub-area width is less than or equal to the detection range, the search and rescue path is determined to be a straight line path, and when the sub-area width is greater than the detection range, the search and rescue path is determined to be a broken line path. In this way, different search and rescue paths are formulated according to the coverage of the search and rescue sub-area by the detection range, so as to ensure that the search and rescue personnel can cover the sub-area to be searched and rescued according to the search and rescue path, thereby ensuring the reliability of the search and rescue operation.

[0055] In one possible example, determining that the search and rescue path is a zigzag path includes: determining the search and rescue length of the sub-area to be searched based on the first coordinate position and the second coordinate position; determining the number of cycles of multiple zigzag segments in the zigzag path based on a third proportional relationship between the search and rescue length and the radius of the detection range, the zigzag path being formed by the cycle of multiple zigzag segments; determining the length of each of the multiple zigzag segments based on the width of the sub-area; and constructing a zigzag path based on the length of a single zigzag segment and the number of cycles.

[0056] The number of loops of the broken line path is determined according to the proportional relationship between the search length and the radius of the detection range. For example, if the radius of the detection range is 20m and the search length is 80m, the number of loops is 80÷20*2=2 times. Figure 5 , Figure 5 5 is a schematic diagram of a search and rescue path provided in an embodiment of the present application. The length h1 in the path 501 is the diameter length of the detection range, and the length h2 is the radius length of the detection range. Figure 5 The path 501 shown can ensure that the search range of a single rescuer covers the sub-area to be searched.

[0057] It can be seen that in this example, the search and rescue length of the sub-area to be searched and rescued is determined according to the first coordinate position and the second coordinate position, the number of cycles of multiple broken line segments in the broken line path is determined according to the third proportional relationship between the search and rescue length and the radius of the detection range, and the length of each broken line segment in the multiple broken line segments is determined according to the width of the sub-area, and the broken line path is constructed according to the length of a single broken line segment and the number of cycles. In this way, a reasonable search and rescue path is formulated according to the detection range and the search and rescue length, so that the search and rescue personnel can cover the sub-area to be searched and rescued according to the search and rescue path, and the search and rescue efficiency is improved while ensuring comprehensive search and rescue.

[0058] S250: Send a search and rescue instruction to the beacon search and rescue device.

[0059] The search and rescue instructions are used to instruct the search and rescue personnel to perform the search and rescue operation according to the search and rescue path. The search and rescue instructions include: information about the area to be searched and rescued and information about the search and rescue path.

[0060] Specifically, the information of the area to be searched and rescued and the information of the search and rescue path may be coordinate information or image information of a satellite map, and the search and rescue path of the rescue personnel may be indicated in the satellite map by marking the path.

[0061] It can be seen that in the embodiment of the present application, the server in the search and rescue system first receives the distress signal of the Beidou watch, the distress signal is associated with the distress event of the Beidou watch, and the distress signal carries the initial positioning information for indicating the position of the Beidou watch. Secondly, the area to be searched and rescued in the current avalanche event is determined according to the initial positioning information. The area to be searched and rescued refers to the area covered by snow due to the avalanche event. Then, according to the detection range of the beacon search and rescue equipment and the number of search and rescue personnel, the area to be searched and rescued is divided into multiple sub-areas to be searched and rescued. The beacon search and rescue equipment is a device used by the search and rescue personnel to receive distress beacons. The detection range is the signal coverage range of the beacon search and rescue equipment to detect the beacon of the Beidou watch. Then, according to the sub-areas to be searched and rescued and the detection range, the search and rescue paths of the multiple sub-areas to be searched and rescued are determined to ensure that the area covered by the search and rescue personnel when searching and rescuing according to the search and rescue path includes the area to be searched and rescued. Finally, a search and rescue instruction is sent to the beacon search and rescue equipment. The search and rescue instruction is used to instruct the search and rescue personnel to perform search and rescue actions according to the search and rescue path. The search and rescue instruction includes: information about the area to be searched and rescued and information about the search and rescue path. In this way, by reasonably dividing the search and rescue area through the detection range of search and rescue personnel and search and rescue equipment, the rescue efficiency can be improved, the rescue time can be shortened, and the possibility of buried people being rescued in time can be increased.

[0062] In one possible example, determining the search and rescue paths for multiple sub-areas to be searched and rescued also includes: after dividing the area to be searched and rescued into multiple sub-areas to be searched and rescued according to a second proportional relationship, comparing the number of rescue personnel and the number of sub-areas in the sub-areas to be searched and rescued; if the number of rescue personnel and the number of sub-areas are in integer multiples, formulating a first allocation plan, the first allocation plan is used to characterize that the rescue personnel are evenly distributed to the multiple sub-areas to be searched and rescued; if the number of rescue personnel and the number of sub-areas are not in integer multiples, formulating a second allocation plan, the second allocation plan is used to characterize that the rescue personnel are first evenly distributed to the sub-areas to be rescued, and the remaining rescue personnel are sequentially added to the multiple sub-areas to be rescued; determining the number of rescue personnel in the sub-areas to be searched and rescued according to the first allocation plan or the second allocation plan; formulating a search and rescue plan according to the number of rescue personnel in the sub-areas to be searched and rescued; and sending the search and rescue plan to the beacon search and rescue device.

[0063] Specifically, if the number of rescuers and the number of sub-areas are in integer multiples, for example, the number of rescuers is 8 and the number of sub-areas is 4, then two rescuers are evenly allocated to each sub-area; if the number of rescuers and the number of sub-areas are not in integer multiples, for example, the number of rescuers is 10 and the number of sub-areas is 4, then two rescuers are preferentially allocated to each sub-area, and the remaining personnel are evenly allocated to the sub-areas to be searched and rescued to be responsible for the search and rescue operations.

[0064] It can be seen that in this example, by comparing the number of rescue personnel and the number of sub-areas in the search and rescue sub-area, an adaptive search and rescue personnel allocation plan is formulated to ensure that there are search and rescue personnel in each search and rescue area, thereby improving the search and rescue effect and effectively protecting the safety of the buried people.

[0065] In a possible example, a search and rescue plan is formulated based on the number of rescuers in the sub-area to be searched and rescued, including:

[0066] When it is determined that at least two or more rescuers are deployed in the sub-area to be searched and rescued, it is determined that some of the rescuers in the sub-area to be searched and rescued start the search and rescue operation from the search and rescue starting point of the sub-area to be searched and rescued, and the remaining rescuers start the search and rescue operation from the search and rescue end point of the sub-area to be searched and rescued;

[0067] When it is determined that one rescuer is configured in the sub-area to be searched and rescued, the search and rescue is performed according to the search and rescue path.

[0068] Specifically, if the number of rescuers and the number of sub-areas are integer multiples, for example, the number of rescuers is 8 and the number of sub-areas is 4, then each sub-area includes 2 rescuers. In each sub-area, rescuer a conducts search and rescue from the search and rescue starting point, and rescuer b gives priority to going to the search and rescue end point, and conducts search and rescue simultaneously with rescuer a from the search and rescue end point, forming a counter-search and rescue.

[0069] It can be seen that in this example, the search and rescue plan is reasonably adjusted according to the different number of people in each sub-area to be searched and rescued. While ensuring the search and rescue effect and not missing the search and rescue coverage area, the search and rescue efficiency is improved, the time that the people in distress are buried in the snow is reduced, and the safety of the people in distress is improved.
