[0043] The component waterproof shell 6 protects the components in the rescue device that are easily damaged by water, provides the installation and fixing position of each component, and the streamlined shape can reduce the resistance of the rescue device in water.

[0044] The state of the rescue device provided by the utility model can be divided into four states: search state, advancing state to the drowning person, wrapping the drowning person and floating state, and returning state.

[0045] The working process of the rescue device will be described in detail below according to different states.

[0046] When the rescue device provided by the utility model is in the search state, as shown in Figure 2

[0047] In the search state, the air bag is in an uninflated state;

[0048] In the search state, the battery and charging device 5 detect the battery power under the control of the main control device 9 and charge as needed according to the detection result.

[0049] In the search state, the infrared camera device 1 transmits real-time images to the drowning state comparison device 8, as shown in Figure 4 The drowning state comparison device 8 receives the comparison start signal from the main control device 9, converts the input analog voltage signal into a digital signal, compares the conversion result with the threshold memory output value through a logic Xor gate, and transmits the comparison result to the main control device 9 through the output terminal U5.

[0050] In the advancing state to the drowning person:

[0051] ​The direction determination device 16 continuously tracks the location of the drowning person and transmits the direction information to the main control device 9. The main control device 9 sends a propulsion signal to the underwater propulsion device 4. The underwater propulsion device 4 propels the device to the drowning person, and then the device enters the state of wrapping the drowning person and floating.

[0052] Meanwhile, while moving towards the drowning victim, the sound and light alarm device 2 in this rescue device continuously emits sound and flashing alarm signals to alert others to avoid the area or to obtain assistance from others.

[0053] While the drowning person is wrapped and floating, refer to the attached document. Figure 3 After receiving signals from the infrared camera device 1 and the direction judgment device 16, the main control device 9 sends a propulsion signal to the underwater propulsion device 4. The underwater propulsion device 4 propels the rescue device to a position directly below the drowning person. Subsequently, the main control device 9 sends an inflation signal to the inflatable airbag 7. The inflatable airbag 7 inflates rapidly. After the bowl-shaped or butterfly-shaped inflatable airbag 7 inflates rapidly below the drowning person, it encloses the drowning person in the inflated airbag and floats to the surface of the water. The water accumulated in the bowl-shaped or butterfly-shaped inflatable airbag 7 is discharged outside the bowl-shaped or butterfly-shaped space formed by the airbag through multiple one-way drainage holes 12 on the bottom and sides of the inflatable airbag 7, ensuring that the drowning person enclosed inside is not submerged in water. Then, the rescue device enters the return state.

[0054] In the return phase, the main control device 9 receives the position information from the positioning device 3 and sends propulsion signals and position information to the underwater propulsion device 4. The inflatable airbag 7 propels the device back to its original starting point.

[0055] In the return-to-base state, the audible and visual alarm device 2 in this rescue device continuously emits sound and flashing alarm signals to alert others to avoid the area or to obtain assistance from others.

[0056] Appendix Figure 4 The comparison threshold stored in the threshold memory U6 ​​shown is a threshold for judging drowning patterns determined in advance by drowning big data and artificial intelligence software. This threshold is written into the threshold memory U6 ​​before the product leaves the factory. The threshold memory U6 ​​only serves to store this threshold and output it to the input of the XOR gate. Artificial intelligence software includes, but is not limited to, software like Wenxin Yiyan and Qianyi Tongwen. This application does not involve improvements to artificial intelligence software; it is limited to inputting the drowning comparison results (digital signals, etc.) collected by the drowning state comparison device into existing artificial intelligence software to obtain the drowning state comparison judgment threshold for the human drowning pattern recommended by artificial intelligence.

[0057] In this invention, the control information between the main control device and other modules is implemented through the pins of the main control device chip. That is, the main control device connects to other modules through pre-set pins, and the control signal is either high or low level. For example, when the level is high, the drowning state comparison device 8 is activated; when the level is low, the drowning state comparison device 8 stops working. The corresponding control method is existing technology in this field, and only requires corresponding settings according to the instruction manual of the main control device; this invention will not elaborate further. For example, the microcontroller model of the main control device is AT89C51.

[0058] The embodiments of this utility model have at least the following beneficial effects:

[0059] (1) Even if the drowning person has lost consciousness and is in a coma, the rescue device provided by this utility model can successfully carry out the rescue even if the drowning person does not actively cooperate.
