[0031] Please refer to Figure 1 , Figure 1 which is a system architecture diagram of a search and rescue system provided by the application embodiment of the present application, 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 based on the initial positioning information.

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

[0041] In a possible example, the search and rescue system further includes a drone. The drone is equipped with 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 includes: sending an image acquisition message to the drone, where the image acquisition message is used to instruct the drone to go to the area indicated by the positioning information for image acquisition; receiving the on-site image information of the avalanche event sent by the drone; based on the on-site image information of the avalanche event, determining the first coordinate position and the second coordinate position of the avalanche event, where the first coordinate position represents the starting position of the avalanche event, and the second coordinate position represents the ending position of the avalanche event; and determining the lateral coverage range of the avalanche event; determining the area to be searched and rescued according to the first coordinate position, the second coordinate position, and the lateral coverage range.

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

[0043] Specifically, please refer to Figure 3 , Figure 3 which 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. As Figure 3 shown, the avalanche coverage area 300 includes: The first coordinate position 301 represents the coordinate of the avalanche occurrence position, generally located at a relatively high altitude on the snow mountain, such as the top of the mountain or the mountainside; the second coordinate position 302 represents the coordinate of the avalanche stop position, generally at a position with a relatively lower terrain than the first position coordinate, such as the foot of the mountain; and the lateral coverage range judged according to the image information, such as Figure 3 the coverage range formed between the third coordinate position 303 and the fourth coordinate position 304 shown in

[0044] Among them, the coordinate position indicates the outermost coordinates of the avalanche coverage area. That is, based on the above first position coordinate 301, second position coordinate 302, third position coordinate 303, and fourth position coordinate 304, the area to be searched and rescued determined is the search area with the widest range, including the entire avalanche coverage area.

[0045] It can be seen that in this example, by sending a message for collecting images to the drone, the on-site image information of the avalanche event sent by the drone is received. 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, and the lateral coverage range of the avalanche event is determined. 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 on-site avalanche coverage is accurately fed back through the image information, so as to improve the accuracy and reliability of determining the search and rescue range, which is beneficial to improving the success rate of search and rescue operations.

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

[0047] Among them, the beacon search and rescue device 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 device for detecting the Beidou wristwatch beacon. Among them, the detection range is the signal range within which the beacon search and rescue device can receive distress signals.

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

[0049] Among them, when the first search width is greater than the second search width, it means that the number of search and rescue personnel is small, and the area to be searched and rescued needs to be divided according to the number of personnel, and the number of personnel is equal to the number of sub-areas to be searched and rescued; specifically, please refer to Figure 4a , Figure 4a is a schematic diagram of the scenario of a sub-area to be searched and rescued provided by an embodiment of the present application. As Figure 4aAs shown, if the number of rescue personnel 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, according to the number of rescue personnel, the area to be searched is evenly divided into 4 areas, namely the first sub-area to be searched 4011, the second sub-area to be searched 4012, the third sub-area to be searched 4013, and the fourth sub-area to be searched 4014. In each sub-area to be searched, a rescue personnel carries a beacon search and rescue device. Thus, by dividing the number of sub-areas to be searched according to the number of people, while ensuring the rescue effect, the comprehensiveness of the search for the area to be searched is ensured.

[0050] Among them, when the first search width is less than or equal to the second search width, it means that the number of search personnel is large. Therefore, according to the diameter of the detection range, the area to be searched is divided to ensure that each sub-area to be searched can fully receive the search beacon. Please refer to Figure 4b , Figure 4b FIG. is a schematic diagram of another scenario of the sub-area to be searched provided by an embodiment of the present application. As Figure 4b shown, for the avalanche area 300, it is divided according to the detection range diameter of the beacon search and rescue device 130 as shown in Figure 1 . As shown in Figure 4b , the area to be searched is divided into 5 parts, including the fifth sub-area to be searched 4021, the sixth sub-area to be searched 4022, the seventh sub-area to be searched 4023, the eighth sub-area to be searched 4024, and the ninth sub-area to be searched 4025. Among them, each sub-area to be searched includes at least one rescue personnel, that is, at least one beacon search and rescue device 130. It should be understood that it also includes the situation shown in the fifth sub-area to be searched 4021, including two rescue personnel and carrying two beacon search and rescue devices. Thus, the search area can be reasonably divided according to the rescue resources, the search efficiency can be improved, and the success rate of the search operation can be enhanced.

[0051] S240. According to the sub-areas to be searched and the detection range, determine the search paths of multiple sub-areas to be searched to ensure that the areas covered when the rescue personnel search according to the assigned search paths include the area to be searched.

[0052] In a possible example, determining the search paths of multiple sub-areas to be searched according to the sub-areas to be searched and the detection range includes: determining the width of each sub-area among the multiple sub-areas to be searched; 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 path as a straight-line path, where the straight-line path refers to a straight-line route between the search starting point and the search ending point; when the sub-area width is greater than the detection range, determining the search path as a zigzag path, where the zigzag path refers to a zigzag route between the search starting point and the search ending point.

[0053] Among them, if it is determined according to the above judgment that when the first search width is greater than the second search width, there will be a situation where the width of the sub-region is greater than the detection range. At this time, a zigzag path is adopted so that the search signal reception range of the rescue personnel covers the entire sub-region to be searched without missing the search coverage range, ensuring the search effect; if the first search width is less than or equal to the second search width, the width of the sub-region is equal to the detection range. At this time, a straight-line path is adopted, that is, it can meet the search range of the search and rescue personnel to cover the sub-region to be searched.

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

[0055] In a possible example, determining the search path as a zigzag path includes: determining the search length of the sub-region to be searched according to the first coordinate position and the second coordinate position; determining the number of cycles of multiple broken lines in the zigzag path according to the third proportional relationship between the search length and the radius of the detection range, and the zigzag path is formed by cycling multiple broken lines; determining the length of each broken line among multiple broken lines according to the width of the sub-region; and constructing the zigzag path according to the length of a single broken line and the number of cycles.

[0056] Among them, according to the proportional relationship between the search length and the radius of the detection range, the number of cycles of the zigzag path is determined. For example, if the radius of the detection range is 20m and the search length is 80m, the number of cycles is 80÷20*2 = 2 times. Please refer to Figure 5 , Figure 5 is a schematic diagram of a search path provided by 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. As Figure 5 shown, the path 501 can ensure that the search range of a single search and rescue personnel covers the sub-region to be searched.

[0057] It can be seen that in this example, by determining the search and rescue length of the sub-region to be searched and rescued based on the first coordinate position and the second coordinate position, determining the number of cycles of multiple broken line segments in the broken line path according to the third proportional relationship between the search and rescue length and the radius of the detection range, determining the length of each broken line segment in the multiple broken line segments according to the width of the sub-region, and constructing the broken line path based on 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, enabling the search and rescue personnel to cover the sub-region to be searched and rescued along the search and rescue path, improving the search and rescue efficiency while ensuring comprehensive search and rescue.

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

[0059] Among them, the search and rescue instruction is used to instruct the search and rescue personnel to perform search and rescue operations according to the search and rescue path. The search and rescue instruction includes: information on the area to be searched and rescued and information on the search and rescue path.

[0060] Specifically, the information on the area to be searched and rescued and the information on the search and rescue path can be coordinate information, or can also be image information of a satellite map, and the search and rescue path of the search and rescue personnel is 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 wristwatch. The distress signal is associated with the distress event of the Beidou wristwatch, and the distress signal carries the initial positioning information for indicating the position of the Beidou wristwatch. 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 device and the number of search and rescue personnel, the area to be searched and rescued is divided into multiple sub-regions to be searched and rescued. The beacon search and rescue device 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 device for detecting the Beidou wristwatch beacon. Then, according to the sub-regions to be searched and rescued and the detection range, the search and rescue paths of multiple sub-regions to be searched and rescued are determined to ensure that the area covered by the search and rescue personnel along the respective search and rescue paths includes the area to be searched and rescued. Finally, a search and rescue instruction is sent to the beacon search and rescue device. The search and rescue instruction is used to instruct the search and rescue personnel to perform search and rescue operations according to the search and rescue path. The search and rescue instruction includes: information on the area to be searched and rescued and information on the search and rescue path. In this way, by reasonably dividing the area to be searched and rescued through the detection range of the search and rescue personnel and the search and rescue device, the rescue efficiency can be improved, the rescue time can be shortened, and thus the possibility of the buried person being rescued in time can be increased.

[0062] In a possible example, determining the search and rescue paths for multiple sub-areas to be searched and rescued further includes: after dividing the area to be searched and rescued into multiple sub-areas to be searched and rescued according to the second proportional relationship, comparing the number of rescue personnel with the number of sub-areas to be searched and rescued; if the number of rescue personnel is an integer multiple of the number of sub-areas, formulating a first allocation plan, where the first allocation plan is used to represent evenly distributing the rescue personnel to multiple sub-areas to be searched and rescued; if the number of rescue personnel is not an integer multiple of the number of sub-areas, formulating a second allocation plan, where the second allocation plan is used to represent first evenly distributing the rescue personnel to the sub-areas to be rescued and then sequentially supplementing the remaining rescue personnel to 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 based on 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 equipment.

[0063] Specifically, if the number of rescue personnel is an integer multiple of the number of sub-areas, for example, the number of rescue personnel is 8 and the number of sub-areas is 4, then on average, each sub-area has two rescue personnel; if the number of rescue personnel is not an integer multiple of the number of sub-areas, for example, the number of rescue personnel is 10 and the number of sub-areas is 4, then first allocate two rescue personnel to each sub-area, and then evenly distribute the remaining personnel to the sub-areas to be searched and rescued in sequence 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 with the number of sub-areas to be searched and rescued, formulating an appropriate search and rescue personnel allocation plan ensures that there are search and rescue personnel in each area to be searched and rescued, improves the search and rescue effect, and effectively protects the safety of the buried personnel.

[0065] In a possible example, formulating a search and rescue plan based on the number of rescue personnel in the sub-areas to be searched and rescued includes:

[0066] When it is determined that there are at least 2 or more rescue personnel configured in the sub-area to be searched and rescued, it is determined that some of the rescue personnel in the sub-area to be searched and rescued start the search and rescue operation from the search starting point of the sub-area to be searched and rescued, and the remaining rescue personnel start the search and rescue operation from the search ending point of the sub-area to be searched and rescued;

[0067] When it is determined that there is 1 rescue personnel configured in the sub-area to be searched and rescued, the search and rescue is carried out according to the search and rescue path.

[0068] Specifically, in the case where the number of rescue personnel is an integer multiple of the number of sub-areas as described above, for example, the number of rescue personnel is 8 and the number of sub-areas is 4, then each sub-area includes 2 rescue personnel. In each sub-area, rescue personnel a starts the search from the search starting point, and rescue personnel b first goes to the search ending point and starts the search synchronously with rescue personnel a from the search ending point to form an oncoming search.

[0069] It can be seen that in this example, since the number of people in each sub-area to be searched and rescued is different, the search and rescue plan is reasonably adjusted, which improves the search and rescue efficiency while ensuring the search and rescue effect and not missing the search and rescue coverage area, reduces the time for the people in distress to be buried under the snow, and improves the safety of the people in distress.
