[0020] like Figure 1 As shown, Figure 1 A lifesaving method based on an intelligent lifebuoy is provided in an embodiment of the present invention, and the method comprises the following steps: S100, receiving a distress instruction, and determining a drowning location based on positioning information in the distress instruction; Specifically, the method provided in this embodiment can be executed by a cloud server, and after receiving the distress command, the cloud server quickly parses the location information.

[0021] S200, searching for a dormant lifebuoy according to the drowning location, determining an estimated rescue time from the searched lifebuoy to the drowning location, selecting a target lifebuoy from the searched lifebuoys according to the estimated rescue time, sending a distress command to the target lifebuoy, and triggering the target lifebuoy to alarm; Specifically, the states of the lifebuoy include a dormant state and an activated state. In the dormant state, some functions of the lifebuoy are limited; in the activated state, all functions of the lifebuoy can be used. After receiving the distress command, the cloud server quickly locks the surrounding dormant lifebuoys according to the drowning location, determines the estimated rescue time from each lifebuoy to the drowning location, selects the target lifebuoy according to the estimated rescue time, and sends a distress command to ensure that at least one lifebuoy responds in linkage. After the lifebuoy detects the distress command, it activates the alarm, sounds the alarm, and flashes the light, so that people around can hear the alarm sound or see the flashing light. Even if the lifebuoy is in a relatively hidden location, it can remind passers-by around to find it quickly, thereby saving rescue time.

[0022] S300, in response to an activation signal sent by a target life buoy, obtaining a position of the target life buoy, and providing real-time navigation according to the position of the target life buoy and a drowning position.

[0023] In this step, after the user finds the target lifebuoy, by pressing the activation button on the target lifebuoy, the target lifebuoy is activated and taken away. The target lifebuoy sends an activation signal to the cloud server. After receiving the activation signal, the cloud server immediately starts the real-time navigation function to accurately guide the rescue personnel to quickly reach the drowning position. According to the navigation information, the rescue personnel carry the lifebuoy and act quickly to ensure effective rescue within the rescue time. In this step, through the guidance of the navigation system, the rescue personnel can quickly reach the location, ensuring that the rescue operation is efficient and accurate, and maximizing the rescue success rate. In some embodiments, a display screen is provided on the lifebuoy. The user can receive the real-time navigation information from the target lifebuoy to the drowning position through the display screen on the lifebuoy or the display interface of the smart terminal. By providing real-time navigation, it is convenient for the rescue personnel to quickly reach the drowning position from the location of the lifebuoy for rescue, thereby improving the rescue efficiency.

[0024] In some embodiments, in S100, the receiving the distress instruction and determining the drowning position based on the positioning information in the distress instruction includes: Receiving a first distress instruction sent by the lifebuoy, parsing the first positioning information of the lifebuoy from the first distress instruction, and determining the drowning position based on the first positioning information; wherein, the first distress instruction includes the first positioning information of the lifebuoy; and / or, receiving a second distress instruction sent by the terminal device, parsing the second positioning information of the terminal device from the second distress instruction, and determining the drowning position based on the second positioning information; wherein, the second distress instruction includes the second positioning information of the terminal device.

[0025] Specifically, when the user discovers a drowning situation, if a lifebuoy is found, the lifebuoy is awakened by pressing the button on the lifebuoy to activate the lifebuoy, and the lifebuoy that sends the first distress instruction is used as the target lifebuoy. The lifebuoy is triggered to send a first distress instruction to the cloud server, and the first distress instruction includes the first positioning information of the lifebuoy; the cloud server parses the first positioning information of the lifebuoy from the first distress instruction and uses the first positioning information as the drowning position.

[0026] If the user's terminal device is installed with a mini-program or application, and registration and location sharing have been completed, the second distress instruction can also be reported through the terminal device. The second distress instruction includes the second positioning information of the terminal device. The cloud server parses the second positioning information of the lifebuoy from the second distress instruction and uses the second positioning information as the drowning position, so that a distress call can be made even when the lifebuoy is not found.

[0027] In some embodiments, the receiving the distress instruction and determining the drowning position based on the positioning information in the distress instruction includes: Receive a distress instruction and identify whether the distress instruction is a first distress instruction or a second distress instruction; wherein, the first distress instruction is sent by a life buoy in an active state, and the second distress instruction is sent by a terminal device; If the distress instruction is the first distress instruction, parse the first positioning information of the life buoy from the first distress instruction, and determine the drowning position based on the first positioning information; wherein, the first distress instruction includes the first positioning information of the life buoy; If the distress instruction is the second distress instruction, parse the second positioning information of the terminal device from the second distress instruction, and determine the drowning position based on the second positioning information; wherein, the second distress instruction includes the second positioning information of the terminal device.

[0028] In some embodiments, in S200, the step of searching for a dormant life buoy according to the drowning position, determining the estimated rescue time from the searched life buoy to the drowning position, and screening a target life buoy from the searched life buoys includes: S211, centering on the drowning position, search for nearby dormant life buoys in the order from near to far, and gradually expand the search range; Generally, when deploying life buoys, multiple life buoys will be placed in an area of the river. In some embodiments, a life buoy group is established according to the deployment area. When an alarm is triggered by one life buoy in the group, nearby life buoys will be searched, and other life buoys will respond synchronously to form a linkage mechanism. Specifically, centering on the drowning position, gradually expand the search radius in a circular range to ensure that all surrounding life buoys are covered, accurately calculate the estimated rescue time for each life buoy to reach the drowning position, preferentially select the target life buoy with the shortest time, send a distress instruction, and achieve a fast linkage response to improve the rescue success rate.

[0029] S212, after searching for a dormant life buoy, plan the optimal rescue path for the searched life buoy, determine the estimated rescue time based on the optimal rescue path, and select the life buoy with an estimated rescue time lower than the time threshold as the target life buoy.

[0030] By planning the optimal path from the life buoy to the drowning position and calculating the corresponding estimated rescue time, it is possible to quickly screen out the life buoys in the group with an estimated rescue time lower than the time threshold, thereby improving the effectiveness of rescue. For example, the time threshold can be set to 5 minutes, and the estimated rescue time is 3 minutes, then the corresponding life buoy is used as the target life buoy to ensure the timeliness of rescue. If the estimated rescue time of each life buoy exceeds the time threshold, search and screen the life buoys again until a target life buoy that meets the conditions is found. By dynamically adjusting the time threshold to adapt to different water environments and rescue requirements, the rescue efficiency is further improved.

[0031] In some embodiments, in S212, the planning of the optimal rescue path for the retrieved lifebuoy includes: Determine the location of the retrieved lifebuoy, use the location of the retrieved lifebuoy as the starting point, and use the drowning location as the end point for optimal path planning to obtain the optimal rescue path.

[0032] Specifically, the lifebuoy reminds by calling nearby people. The location of the target lifebuoy can be used as the starting position, and the optimal path from the location of the retrieved lifebuoy to the drowning location is planned to obtain the optimal rescue path.

[0033] In some embodiments, the method further includes: S221, obtain the location of the target lifebuoy, search for nearby terminal devices in order from near to far with the location of the target lifebuoy as the center, and gradually expand the search range; As described above, if the user's terminal device installs a mini-program or application and completes registration and location sharing, as a registered intelligent terminal, the user of this intelligent terminal is regarded as potential rescue force.

[0034] S222, after the terminal device is retrieved, plan the optimal rescue path for the retrieved terminal device, determine the estimated rescue time based on the optimal rescue path, select the terminal device with an estimated rescue time lower than the time threshold as the target device, and send a distress instruction to the target device to trigger the target device to give an alarm.

[0035] Specifically, the cloud server dynamically adjusts the search radius according to the location of the target lifebuoy to ensure all terminal devices within the coverage range, accurately calculates the estimated time for each terminal device to reach the drowning location via the target lifebuoy, preferentially selects the terminal device with the shortest time, sends a distress instruction, and realizes the linkage of multiple terminal devices; in addition to being able to call the people near the target lifebuoy, it can also find more rescuers through the registered terminal devices, further improving the rescue efficiency.

[0036] In some embodiments, in S222, the planning of the optimal rescue path for the retrieved terminal device includes: Determine the location of the retrieved terminal device, plan the optimal path from the location of the target device to the location of the target lifebuoy, and from the location of the target lifebuoy to the drowning location to obtain the optimal rescue path.

[0037] Specifically, after receiving the distress instruction through the intelligent terminal, the user will first view the navigation information from the user to the target lifebuoy through the intelligent terminal. After getting the target lifebuoy, perform real-time navigation based on the target lifebuoy and the drowning location.

[0038] In some embodiments, the method further includes: In response to an activation signal sent by the target lifebuoy, mark the target lifebuoy as the activated state.

[0039] Specifically, the user presses the stop alarm button on the target lifebuoy. After user intervention, the target lifebuoy stops alarming and reports the stop alarm information to the cloud server. The cloud server updates the status of the target lifebuoy in real time, coordinates actions, and improves the efficiency of searching for the lifebuoy.
