[0034] Please refer to Figs. 1-2 The utility model provides technical scheme: including 1 water surface device 100 and multiple underwater devices 200, the underwater device 200 includes:
[0035] The underwater device 200 includes:

[0039] The encoding module 204, which is connected to the underwater microcontroller 202, is programmed to send a specific code before sending the emergency signal, so as to distinguish the signal source for the surface device 100;
[0040] The surface device 100 comprises:
[0041] The surface power supply 101 is a portable battery or a power grid supply;
[0042] The surface microcontroller 102 controls other modules of the surface device 100;
[0043] The receiving module 103 comprises a radio frequency receiving circuit and an ultrasonic transducer, which are used to receive the low-frequency radio signal and the ultrasonic signal sent by the transmitting module 203 of the underwater device 200 respectively, and convert the radio signal and the ultrasonic signal into an electric signal, which is then sent to the decoding module 104;
[0044] The decoding module 104 analyzes the electric signal received by the receiving module 103, and identifies the identification code of the underwater transmitter, and the output is input to the surface microcontroller 102;

[0046] The display module 106 receives the signal from the surface microcontroller 102, and displays the corresponding underwater device 200 according to the identification code of the underwater transmitter identified by the decoding module 104.
[0047] A microcontroller is a small computing device that can both receive input, such as from a button or sensor on the device, and control output, such as activating a transmitter module or a display module. This device typically has a simple form of programming built in that controls the various functions of the device. When we program it, we can specify that it perform a particular action under certain conditions. In this embodiment, when the user triggers the distress signal, the underlying program of the microcontroller is activated, which sends a specific code for that device first, followed by the distress signal. This code and the distress signal are sent out by the transmitter module and are decoded at the receiving device to determine which device sent the signal. One common way to set the identification code is to use a numerical or alphabetical code called Morse Code to represent each device. Each device has a unique Morse Code that is used to send out a distress signal via radio or other means of communication in an emergency. Specifically, the Morse Code is first programmed into the microcontroller. The microcontroller sets the code for each device through a programming language, which can be a string of numbers, letters, or a combination of numbers and letters. Then, whenever the device needs to send a distress signal, the microcontroller sends this unique device code first, followed by the distress signal. The receiving device decodes the code first before processing the distress signal.
[0048] In other preferred embodiments, the modules of the underwater device 200 are encapsulated in a waterproof housing. The housing can prevent water and other harmful substances from entering and causing damage or corrosion to the modules. The device encapsulated in the waterproof housing can work for a long time in harsh environments such as deep sea without worrying about damage due to water infiltration. The waterproof housing can prevent changes in water or humidity from affecting the performance of the device, maintaining the stable working state of the device. The waterproof housing prevents short circuits caused by water and electricity, improving the safety of the device. Since the modules are encapsulated in a housing, the overall stability of the device is increased, and it is also convenient for the operator to carry and use. The waterproof housing can also prevent damage to the device caused by misoperation during underwater work.
[0049] In other preferred embodiments, the underwater device 200 can be fixed to the helmet or diving suit in a convenient position for touching. In an emergency, the diver can directly access the device and immediately initiate emergency communication without having to search for or remove the device from the body, greatly facilitating emergency operations and saving valuable time. Fixing the device to the helmet or diving suit can prevent the device from falling off or drifting during underwater activities, reducing the risk of losing the device. Fixing the device to the diving equipment allows the diver's hands to be free from holding the device, allowing for more freedom to perform other activities.
[0050] In other preferred embodiments, the warning module 105 is an audible and light alarm. Strong prompt effect: sound and light are the most direct and influential ways for human beings to receive information, that is, they can quickly attract people's attention and can be easily determined to be the source. The sound and light of the audible and light alarm can quickly spread to a certain range, thereby ensuring that the information can be delivered to more people. People of any language can understand the alarm information of the audible and light alarm, which is incomparable to the expression of words. In a noisy environment or an environment with poor visibility, the audible and light alarm is particularly obvious and can provide a stronger warning effect. The dual warning of sound and light can be more noticeable, and it also improves the urgency and severity of the warning
[0051] In other preferred embodiments, the display module 106 is an indicator light indicating the name of the personnel equipped with the corresponding underwater device 200. In an emergency, the identity of the diver in distress can be quickly determined through this indicator light, and the rescue operation can be quickly started. This improves work efficiency and also helps to improve the safety of the workplace, facilitating the management and cooperation of the team.
[0052] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
