[0058] Specifically, before the small life support system of the submersible is used, it is first checked whether the modules can be used normally and whether the operating functions can be used normally, so as to prepare for the next use and put the system into a standby state.

[0060] Oxygen cylinder 110, oxygen cylinder 110 is a high compression ratio small oxygen cylinder with a new type of nano material coating. The nano material coating is made of multiple layers of nano-scale polymer films and metal oxide particles. The coating can effectively fill the microscopic pores of the bottle material to prevent oxygen leakage, and at the same time enhance the pressure resistance of the bottle, so that the oxygen storage pressure is greatly improved compared with the traditional oxygen cylinder. According to the storage capacity and pressure relationship formula: PV = nRT, P is the oxygen pressure, V is the volume of the oxygen cylinder, n is the amount of oxygen substance, R is the gas constant, and T is the temperature, the oxygen storage capacity of the oxygen cylinder under different pressures can be calculated, so as to facilitate the determination of the optimal storage pressure in combination with the nano material coating;

The following is a method for predicting oxygen demand:

[0062] Let the state variable X k =[O 2 ,V,R], respectively represent the oxygen concentration, diver's movement speed and breathing rate, and the state transition direction is X k+1 =AX k +BU k +W k , the observation equation is Z k =HX k +V k , where A is the state transfer matrix, B is the control input matrix, and U k is the control input vector, Wk is the process noise vector;

The multiple security unit 130 is used to collect the diver's motion state, breathing frequency and cabin environment data through multiple sensors;

[0064] Specifically, the main oxygen concentration sensor 131 is used to accurately detect the oxygen concentration in the cabin in real time. The backup sensor 132 serves as a backup. When the main sensor 131 fails, the backup sensor 132 is immediately put into use to ensure uninterrupted monitoring. The oxygen leakage detection device 133 can quickly detect oxygen leakage. Once a leak is detected, the emergency shutdown procedure is immediately triggered to ensure the safety of the diver.

[0065] Among them Figure 1-Figure 4 As shown, the carbon dioxide processing module 200 includes:

[0066] An absorption tank 210, wherein a composite carbon dioxide absorbent is arranged inside the absorption tank 210, and the absorption tank 210 is used to cooperate with the airflow generated by the silent fan 220 to absorb and purify the carbon dioxide in the cabin;

[0067] A silent fan 220, which is used to drive the air circulation in the cabin so that the carbon dioxide can contact the composite carbon dioxide absorbent;

[0068] The concentration monitoring device 230 feeds back the monitoring data to the processing memory 600 in real time through the system line to ensure that the carbon dioxide concentration in the cabin is always within the safe range;

[0069] Specifically, the composite carbon dioxide absorbent is an existing technology. Through a special chemical synthesis process, the traditional chemical absorbent is loaded on the surface of nanoporous materials and inside the micropores to improve the absorption efficiency. The silent fan 220 adopts magnetic levitation bearing technology. Compared with traditional fans, it has lower noise and higher efficiency. Its power can be used using the computational fluid dynamics (CFD) algorithm to simulate and analyze the airflow in the air duct, establish the fluid control equation in the air duct, and then obtain the fan parameters to improve the carbon dioxide treatment efficiency.

[0070] Among them Figure 1-Figure 5As shown, the temperature and humidity adjustment module 300 includes a temperature and humidity sensor 310, a semiconductor cooling and heating element 320 and a dehumidification and humidification device 330. The temperature and humidity sensor 310 is used to monitor the temperature and humidity data in the cabin in real time and transmit the above data to the processing memory 600. The semiconductor cooling and heating element 320 and the dehumidification and humidification device 330 are used to perform corresponding temperature and humidity adjustment operations according to the temperature and humidity range preset in the processing memory 600;

[0071] Specifically, the temperature and humidity adjustment module 300 adopts a combination of semiconductor cooling and heating technology and dehumidification and humidification technology. It monitors the temperature and humidity data in the cabin in real time through the temperature and humidity sensor 310, and transmits the data to the processing memory 600. The processing memory 600 controls the semiconductor cooling and heating element 320 and the dehumidification and humidification device 330 according to the preset temperature and humidity range, thereby achieving precise adjustment of the temperature and humidity in the cabin and creating a comfortable working environment for the divers.

[0072] Among them Figure 1-Figure 6 As shown, the pressure balance module 400 includes a pressure sensor 410, an electric valve 420 and a pressure pipeline. The pressure sensor 410 is used to monitor the internal and external pressure difference of the submersible in real time, and transmit the above pressure data to the processing memory 600 through the system line. The electric valve 420 is used to perform the corresponding valve opening operation according to the pressure adjustment value preset in the processing memory 600;

[0073] Specifically, the pressure in the cabin is replenished or exhausted through the pressure pipeline to achieve rapid and precise adjustment of the pressure in the cabin, ensuring that the pressure in the cabin and the external water pressure always maintain a proper balance, effectively avoiding damage to the diver's body caused by pressure changes.

[0074] Among them Figure 1-Figure 7 As shown, the emergency standby module 500 includes an emergency oxygen cylinder 510, a manual valve 520, a carbon dioxide absorption device 530 and an emergency pipeline. The emergency oxygen cylinder 510 adopts an independent high-pressure gas storage tank, and the carbon dioxide absorption device 530 adopts a disposable chemical absorption bag;

[0075] Specifically, when a fault occurs, the emergency backup module 500 starts automatically, the emergency oxygen cylinder 510 delivers oxygen to the cabin through the emergency pipeline, and absorbs the exhaled carbon dioxide through the disposable chemical absorption bag. The emergency oxygen cylinder 510 adopts an independent high-pressure gas storage tank, which is made of high-strength and lightweight composite materials to ensure that enough emergency oxygen is stored in a limited space, and can provide divers with sufficient oxygen supply in emergency situations. The manual valve 520 is made of sturdy and durable stainless steel with good sealing and operating feel. Even in extreme environments, divers can operate it easily and accurately to control the output flow of emergency oxygen. The disposable chemical absorption bag is also filled with carbon dioxide absorbent, which can quickly absorb the carbon dioxide exhaled by the diver, maintain the fresh air in the emergency environment, and ensure the basic survival needs of the diver.

[0076] Among them Figure 1-Figure 2 As shown, a fault diagnosis module 700 for judging whether a pipeline or sensor at a corresponding node fails is provided on one side of the oxygen supply module 100. The fault diagnosis module 700 includes a fault judgment unit 710 and an indicator light 720 which are electrically connected. The fault judgment unit 710 is used to identify the fault conditions of different sensors and circuits, and prompts the sensor and circuit whether they meet the fault conditions through the indicator light 720. Through the fault judgment unit 710, the circuit of the sensor and circuit can be inspected to avoid the circuit short circuit. When the sensor and circuit fail, the indicator light 720 emits a red light to facilitate subsequent operations.

[0077] Specifically, the fault diagnosis module 700 can quickly determine the location and type of the fault. The indicator light 720 prompts the fault condition with different colors and flashing frequencies, which is convenient for divers to troubleshoot and repair the fault according to the prompts. The fault diagnosis module 700 adopts a fault diagnosis algorithm based on the Bayesian network to build a Bayesian network model. The sensor data of each module is used as a node, and the module fault state is used as a hidden node. The network parameters are learned through known fault sample data to determine the conditional probability between nodes. When abnormal data is detected, the Bayesian formula is used to Calculate the probability of failure of each module to quickly locate the fault point.

[0078] Among them Figure 1-Figure 2 As shown, a human-computer interaction interface 800 is provided on one side of the processing memory 600. The processing memory 600 and the human-computer interaction interface 800 are electrically connected through a system line. The human-computer interaction interface 800 is used to display multiple environmental parameters in real time and adjust the operating parameters of each module based on the above parameter characteristics. The environmental parameters include but are not limited to oxygen concentration, carbon dioxide concentration, temperature, humidity and pressure.

[0079] Among them Figure 2As shown, the human-computer interaction interface 800 is internally provided with a data recording and analysis module 810 and an early warning module 820. The data recording and analysis module 810 is used to automatically record the change data of various environmental parameters in the cabin over a period of time, and automatically update and retrospectively display the historical data in the form of charts based on the above-mentioned change data, so as to facilitate the operator to analyze the change trend of the environmental parameters. The early warning module 820 is used to issue early warning prompts for possible abnormal situations according to the threshold value preset by the processing memory 600.

[0080] Specifically, when a diver finds that a certain parameter deviates from the normal range, he or she can operate on the human-computer interaction interface 800. For example, when the oxygen concentration is close to the lower limit, the diver can touch to adjust the opening of the electronic control valve 121 of the flow control unit 120 in the oxygen supply module 100 to increase the oxygen output; when the carbon dioxide concentration is too high, the speed of the silent fan 220 in the carbon dioxide processing module 200 is adjusted to improve the carbon dioxide absorption efficiency. In addition, the human-computer interaction interface 800 also supports voice control function, and the operation of each module can be realized through voice commands, which effectively saves time.

[0081] Working principle:

[0082] First, the processing memory 600 is started, so that the system automatically performs an initialization self-test operation, and each module is started in sequence: the multiple sensors and flow control unit 120 inside the oxygen supply module 100 start working, and automatically adjust the oxygen supplement amount according to the oxygen concentration in the cabin; the silent fan 220 in the carbon dioxide processing module 200 starts, establishes an air flow cycle, and begins to absorb and purify the carbon dioxide in the cabin; the temperature and humidity adjustment module 300 automatically adjusts the temperature and humidity in the cabin according to the set temperature and humidity range; the pressure sensor 410 of the pressure balance module 400 monitors the cabin pressure in real time, and the electric valve 420 adjusts the pressure according to the instructions of the processing memory 600.

[0083] The diver can then view the oxygen concentration, carbon dioxide concentration, temperature, humidity, and pressure parameters in real time through the human-computer interaction interface 800: if the diver finds that the environmental parameters are all within the normal range, no measures are needed; if the diver finds that a certain parameter deviates from the normal range, the human-computer interaction interface 800 can be used to adjust the parameters; if the diver does not find that a certain parameter deviates from the normal range, the early warning module 820 can issue early warning prompts for possible abnormal situations based on historical data and preset thresholds, and remind the diver to take corresponding measures based on the prompts.

[0084] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present application should be included in the protection scope of the present application.
