[0062] The principles and features of the present invention will be described below. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0063] The present invention provides a dynamic anti-drowning system. Please refer here to Figure 1 as shown, including: a plurality of floating bodies 2, a first positioning module 103, and a central control module 105 communicatively connected to the first positioning module 103;

[0064] The first positioning module 103 is used to obtain the first positioning information of its location, and the central control module 105 is used to determine the target position of each floating body 2 in the current water area according to a preset water area range, a preset water area shape, a preset offshore distance, and the first positioning information. It should be understood that the preset offshore distance is the distance between the preset water area and the first positioning module 103;

[0065] Each floating body 2 is configured with a second positioning module, a driving module, and a microprocessor 202 communicatively connected to the second positioning module and the driving module respectively;

[0066] For each floating body 2, the second positioning module is used to obtain the second positioning information of its location in real time, the microprocessor 202 is used to determine the path information in real time according to the current second positioning information and the current target position, and generate a driving instruction according to the path information, and the driving module is used to control the floating body 2 to move to the target position according to the driving instruction.

[0067] Among them, there are multiple ways to implement the central control module 105 for determining the target position of each floating body 2 in the current water area according to the preset water area range, preset water area shape, preset offshore distance, and the first positioning information. For example, each floating body 2 can be sorted and numbered. After determining the range of the preset water area, the shape of the preset water area, and the preset offshore distance, a coordinate system is established with the first positioning module 103 as the origin, and the preset water area is projected onto this coordinate system, and then the coordinates of each point evenly distributed on the boundary of the preset water area can be determined, which are then used as the respective target positions;

[0068] Subsequently, the microprocessor 202 of each floating body 2 can also compare the second positioning information detected in real time with the corresponding target position. After the deviation between the second positioning information and the target position exceeds the preset range, the path information is re-determined according to the current second positioning information and the target position, and a driving instruction is generated according to the path information. The driving module is used to control the floating body 2 to move to the target position according to the driving instruction, that is, this dynamic adjustment process will continue, so that even if the waves in the preset water area are large, the floating body 2 can still stably hover around the target position.

[0069] Through the obtained first positioning information, as well as the preset water area range, preset water area shape, and preset offshore distance, the target position of each floating body 2 in the current water area can be determined. Subsequently, according to the generated driving instructions corresponding to each floating body 2, the floating body 2 can be controlled to move to the target position to form a safety preset water area identifier surrounded by multiple floating bodies 2.

[0070] Through a dynamic anti-drowning system disclosed by the present invention, a safety preset water area identifier surrounded by multiple floating bodies 2 can be formed quickly and conveniently, effectively preventing children from entering the deep water area and drowning.

[0071] In this embodiment, the information transmission between the central control module 105 and each floating body 2 is realized through a Bluetooth chip.

[0072] More preferably, each floating body 2 is also equipped with a micro sonar detection module for real-time detection of the current water depth;

[0073] The microprocessor 202 is configured to, when the current water depth is greater than the preset value, even after the current water depth is greater than the lowest safety water level, use the position where the first positioning module 103 is located as the target position and re-generate a driving instruction until the microprocessor 202 detects that the current water depth is lower than the preset value, and then use the current second positioning information of the floating body 2 corresponding to the microprocessor 202 as the pending position;

[0074] The central control module 105 is also configured to update the preset offshore distance according to the to-be-determined position, so as to re-determine the target positions of all the floating bodies 2 and generate new driving instructions, thereby ensuring that the safe preset water area enclosed by all the floating bodies 2 can still meet the requirements of the preset water area size and the preset water area shape.

[0075] Due to the change in water depth, or when the water depth of the preset water area is higher than the safe preset value due to the mistake in initially setting the target position of the floating body 2, at this time, the floating body 2 that detects that the water depth is higher than the preset value moves in the direction of the first positioning module 103, i.e., the original path, until it detects that the water depth is lower than the preset value, and updates and adjusts the target positions of all the floating bodies 2, and then regenerates the corresponding driving instructions to control the floating body 2 to move to the new target position.

[0076] Through the above settings, the floating body 2 can dynamically monitor the change in water depth of the current water area in real time and timely adjust the preset water area enclosed by the floating body 2, avoiding the situation that the water depth of the playing area is greater than the preset value due to setting mistakes or water depth changes.

[0077] More preferably, each of the floating bodies 2 is further configured with an alarm module;

[0078] For each of the floating bodies 2, the alarm module is communicatively connected to the microprocessor 202, and the microprocessor 202 is further configured to control the alarm module to give an alarm according to the first preset rule based on the current water depth;

[0079] In this embodiment, the above alarm module may include a buzzer and a plurality of indicator lights. The first preset rule may be that the higher the current water depth, the more dangerous the situation is, and the indicator lights gradually change according to the rule of blue - green - yellow - orange - red, etc. Of course, the color change can be adjusted according to the situation, and this embodiment is not limited thereto;

[0080] Or the above alarm module may also give an alarm in the following manner: if the set preset water area range or and / or the minimum safety water level, i.e., the preset value, is too large, a red light is used for warning to indicate that this setting has a certain degree of danger. As the danger coefficient decreases, the indicator lights will gradually change, i.e., red - orange - yellow - green - blue.

[0081] Through the setting of this alarm module, the players can more clearly observe the boundary of the floating body 2 and the water depth at the corresponding position, further improving the safety.

[0082] More preferably, each of the floating bodies 2 is further configured with a sensing module;

[0083] For each of the floating bodies 2, the sensing module is communicatively connected to the microprocessor 202, and the sensing module is configured to detect and obtain the current position of a preset target in real time;

[0084] The central control module 105 is further configured to determine the positional relationship between the preset target and the area surrounded by each of the floating bodies 2 according to the respective target positions and the current position, and control the alarm module in the preset floating body 2 to give an alarm according to a second preset rule based on the positional relationship. The above-mentioned preset target is usually a player. That is, the central control module 105 is further configured to determine whether the player is approaching the boundary of the safe water area according to the current position of the player fed back by each microprocessor 202 and the safe water area position of the area surrounded by each floating body 2. If the player approaches or leaves the boundary of the safe preset water area, at this time, the central controller can control several floating bodies 2 closest to the player to give a red light warning and turn on the buzzer to remind the player to stay away.

[0085] Through the setting of the sensing module, the position of the preset target in the area surrounded by each of the floating bodies 2 can be detected in real time and fed back through the alarm module, effectively avoiding the danger caused by negligence and preventing the preset target, that is, the player, from ignoring and leaving the area surrounded by the floating bodies 2, thereby causing the risk of drowning.

[0086] In summary, the present invention designs a series of intelligent floating bodies 2. These floating bodies 2 have the ability to detect the water depth (including mud), and can automatically adjust the layout according to the preset parameters of "minimum safe water level", "offshore distance", and "water area range" (the water area shape is defaulted to a rectangle), forming a dynamic and enclosed safe water area.

[0087] When the floating bodies 2 are deployed in the water area, they will adjust their positions according to the "offshore distance" parameter to ensure that all floating bodies 2 are within the safe range of the preset water area set by the user. To cope with dynamic environments such as rippling water, the microprocessor 202 equipped on the small floating body 2 can generate a driving instruction according to the current second positioning information and the current target position, and make an immediate adjustment when the deviation between the second positioning information and the current target position is large to avoid the floating body 2 from deviating; at the same time, when the floating body 2 of the present invention detects that the current water depth in the water area changes until it exceeds the minimum safe water level, it can adjust the preset safe water area surrounded by each floating body 2 to ensure the safety of the players.

[0088] In addition, the floating body 2 of the present invention is also integrated with a sensing module. When a child leaves or approaches the safe water area, the system will give an alarm to timely remind parents and children to pay attention. This function further improves the safety, ensuring that children can enjoy the fun of swimming without being in danger due to negligence.

[0089] In summary, through a series of technical measures, this solution constructs an intelligent, dynamic and reliable child drowning prevention system, fundamentally solving the deficiencies of the existing technologies in preventing child drowning and providing a safer and more reassuring swimming environment for children.

[0090] The present invention also provides a dynamic anti-drowning device, which is described in combination with Figure 2 , Figure 3 and Figure 4 as shown. It includes a dynamic anti-drowning system as described above, and further includes:

[0091] Device main body 1, the device has a top shell 101 and a bottom shell 102 arranged in a snap-fit structure. There is a chamber between the top shell 101 and the bottom shell 102. The first positioning module 103 and the central control module 105 are arranged in the chamber. The chamber is also provided with a plurality of recovery bins 104 for storing the floating bodies 2.

[0092] By using a dynamic anti-drowning system as described above, this dynamic anti-drowning device can form a dynamic safety water area mark through the cooperation of the device main body 1 and a plurality of floating bodies 2. Each floating body 2 can also issue corresponding alarms according to the water depth where it is located, and at the same time, when a preset target leaves the safe water area, it can timely remind parents and visitors, further improving the safety;

[0093] At the same time, a plurality of recovery bins 104 are arranged inside the device main body 1, which can also store the floating bodies 2 together with the device main body 1 when the floating bodies 2 are not in use, facilitating handling together and improving the convenience of use of this device.

[0094] More preferably, as shown in Figure 5 and Figure 6 , the bottom of each floating body 2 is in a conical structure, and a plurality of air outlets 201 are evenly distributed at the bottom. There is a cavity inside the floating body 2. The second positioning module, the microprocessor 202, the driving module, the micro sonar detection module and the sensing module are all arranged in the cavity;

[0095] The driving module includes an air compressor 203, a self-priming pump 204 and a plurality of high-frequency electromagnetic valves 205 that are communicatively connected to the microprocessor 202;

[0096] The suction end of the self-priming pump 204 extends out of the floating body 2, and the air outlet end of the self-priming pump 204 is communicated with the air inlet end of the air compressor 203;

[0097] Each air jet port of the air compressor 203 is respectively communicated with a non-repeating one of the air outlets 201;

[0098] Each of the high-frequency electromagnetic valves 205 is respectively disposed on one of the non-repeating jet ports to control the conduction of the jet port.

[0099] The microprocessor 202 adjusts the air volume and direction ejected from the four jet ports by controlling the working state of the micro air compressor 203 and the opening and closing of the high-frequency electromagnetic valve 205. By precisely controlling the opening sequence, duration, and air flow rate of the jet ports, different directions of propulsion force can be simulated, enabling the floating body 2 to move along a preset path.

[0100] Moreover, there is a solar panel on the top of the floating body 2 of the present invention. The solar panel 206 above the floating body 2 absorbs solar energy and converts it into electricity that can be supplied to the lower part. And it is sealed in the housing by glass with good light transmittance. The lower main part is made of low-density, high-strength, and non-toxic plastic or other materials and can float on the water surface.

[0101] The operation of this device is simple. When in use, only need to turn on the main switch - preset water area range - preset minimum safety water level value - preset offshore distance - turn on the switch of the floating body 2 - put the floating body 2 into the water. Subsequently, the micro air compressor 203 and the high-frequency solenoid valve switch in the floating body 2 continue to work according to the driving instructions of the microprocessor 202, release air through the air distributor, generate propulsion force, and freely disperse to form a visible area according to the set requirements - press the main body switch to recover - store the floating body 2. It should be understood that there are still various ways to realize the recovery of the floating body 2 by pressing the main body switch. For example, taking the position of the first positioning module 103 as the target position to update the target positions of all floating bodies 2 can recover all the floating bodies 2.

[0102] The overall control logic of this embodiment is as follows:

[0103] I. System startup and deployment of the floating body 2

[0104] System startup: The user presses the switch on the device main body 1, and the system starts. At this time, the central controller in the device main body 1 sends a startup instruction to all floating bodies 2 through the 5G Bluetooth networking signal.

[0105] Deployment of the floating body 2: After receiving the startup instruction, the micro air compressor 203 inside the floating body 2 starts to work, releases air through the disc-shaped air distributor, and makes the floating body 2 float on the water surface. At the same time, the Bluetooth chip in the floating body 2 receives the preset parameters (water depth range, offshore distance, target position, etc.) sent by the device main body 1.

[0106] Self - arrangement: Each floating body 2, according to the generated driving instructions, controls the air to be ejected from the four air jets on the air distributor through the internal micro air compressor 203 and high - frequency solenoid valve switch, generates propulsion force, and adjusts its position by itself until all floating bodies 2 form a closed safe preset water area according to the preset parameters.

[0107] II. Water depth detection and processing

[0108] Water depth detection: The micro sonar detector built in the floating body 2 wirelessly detects the depth of water (including mud), and feeds the detection result back to the Bluetooth chip in the floating body 2 in real time.

[0109] Processing logic: The Bluetooth chip compares the detected water depth data with the preset value, i.e., the lowest safe water level. If the actual water depth exceeds the lowest safe water level, the floating body 2 will immediately send an alarm signal to the main body and adjust its own position to avoid entering the dangerous water area. At the same time, the main body will also send a rearrangement instruction to all floating bodies 2 through the 5G Bluetooth networking signal to ensure that the scope and shape of the safe water area meet the preset requirements.

[0110] III. System shutdown and recovery of floating body 2

[0111] System shutdown: After the user finishes swimming, press the middle button on the main body, and the system enters the shutdown procedure.

[0112] Recovery of floating body 2: After receiving the shutdown instruction, the main body sends a recovery instruction to all floating bodies 2 through the 5G Bluetooth networking signal. The floating body 2 adjusts its position according to the instruction and swims towards the shore near the main body. During the swimming process, the micro air compressor 203 and high - frequency solenoid valve switch in the floating body 2 continue to work, release air through the air distributor, and generate propulsion force. When the small floating body 2 reaches the preset shore position, the internal micro air compressor 203 stops working.

[0113] IV. Internal execution instruction logic

[0114] Receiving instructions: The Bluetooth chip in the floating body 2 is responsible for receiving instructions and position feedback signals from the main body.

[0115] Processing instructions: The microprocessor 202 generates driving instructions from the received instructions and controls the working states of the micro air compressor 203 and high - frequency solenoid valve switch according to the driving instructions.

[0116] Executing instructions: When the position needs to be adjusted, the microprocessor 202 controls the micro air compressor 203 to produce air, and controls the air to be ejected from the four air jets on the air distributor through the high - frequency solenoid valve switch, generates propulsion force, and makes the small floating body 2 swim according to the preset logic and path.
