In one embodiment, as shown in fig. 2, a respiratory therapy device control method is provided, and the method is applied to the terminal in fig. 1, where the terminal may represent a respiratory therapy device, and includes the following steps:

step 202, in response to a start-up operation of the respiratory therapy apparatus, entering an operational state in which at least two respiratory therapy control options are displayed.

The respiratory treatment device is a device with respiratory treatment function and is used for respiratory treatment of respiratory disease patients. The respiratory therapy control options refer to options corresponding to respiratory therapy functions in respiratory therapy equipment, and the options can be selected by a user, and different respiratory therapy functions correspond to different respiratory therapy control options. The user may comprise a respiratory patient.

Specifically, the terminal responds to the starting operation of the respiratory therapy equipment by a user, and enters an operation state, and at least two respiratory therapy control options are displayed in the operation state. The terminal can also receive a preset timing starting instruction for the respiratory therapy equipment, the timing starting instruction can carry starting time, and the terminal responds to the timing starting instruction and enters an operating state at the starting time. The terminal may perform a self-test after entering an operational state and display at least two respiratory therapy control options after the self-test is completed.

Step 204, in response to the selection operation of the target respiratory therapy control option in the at least two respiratory therapy control options, acquiring a target respiratory therapy control parameter corresponding to the target respiratory therapy control option, and acquiring first respiratory pressure information and second respiratory pressure information.

The target respiratory instruction control options refer to options corresponding to respiratory treatment functions selected by a user. The target respiratory therapy control parameter refers to a respiratory therapy control parameter corresponding to a target respiratory instruction control option set by a user. The respiratory therapy control parameter refers to a parameter required for respiratory therapy of a respiratory disease patient, and is used for controlling respiratory therapy equipment to perform respiratory therapy according to the therapy parameter. The first respiratory pressure information and the second respiratory pressure information refer to respiratory pressure information acquired by a first pressure sensor and a second pressure sensor in the terminal at the current moment. The respiratory pressure information refers to pressure information of the gas.

Specifically, the terminal responds to the selection operation of a user on a target respiratory therapy control option in at least two respiratory therapy control options, and responds to the input operation of the user on respiratory therapy control parameters, so as to obtain the target respiratory therapy control parameters corresponding to the target respiratory therapy control options. The terminal can also acquire the historical respiratory therapy control parameters corresponding to the historical use time of the target respiratory therapy control options, call the historical respiratory therapy control parameters corresponding to the latest use time, send confirmation information of the historical respiratory therapy control parameters to the user, and take the historical respiratory therapy control parameters as the target respiratory therapy control parameters when the confirmation operation of the user on the historical respiratory therapy control parameters is detected. The terminal can also collect audio signals sent by a user, convert the audio signals into electrical signals and perform voice recognition to obtain voice control instructions, and respond to the voice control instructions to operate, such as 'turning on treatment', 'turning off treatment', 'setting … … parameters', so as to obtain target respiratory treatment control parameters. And then the terminal can acquire the first respiratory pressure information and the second respiratory pressure information corresponding to the current moment through the first pressure sensor and the second pressure sensor. The terminal can also receive the target respiratory therapy control parameters remotely sent by the server management end.

Step 206, calculating an error between the first respiratory pressure information and the second respiratory pressure information to obtain a respiratory pressure information error, and performing flow rate conversion based on the respiratory pressure information error to obtain current respiratory flow rate information.

Wherein the respiratory pressure information error refers to difference information between the first respiratory pressure information and the second respiratory pressure information. Flow rate conversion refers to the process of converting respiratory pressure information errors into respiratory flow rate information. The current respiratory flow rate information refers to flow rate information of the gas.

Specifically, an airflow resistance device is arranged between the first pressure sensor and the second sensor, so that a pressure difference can be formed. The air flow resistance device generates air resistance in the process that air passes through the first pressure sensor and the second pressure sensor, so that the respiratory pressure information acquired by the air passing through the first pressure sensor and the second pressure sensor is inconsistent to form a pressure difference. The terminal acquires first respiratory pressure information corresponding to the first pressure sensor and second respiratory pressure information corresponding to the second sensor, and compares the first respiratory pressure information with the second respiratory pressure information to obtain respiratory pressure information errors. And then the terminal can call a preset flow rate conversion algorithm to calculate the breathing pressure information error, so as to obtain the current breathing flow rate information.

And step 208, calculating the rotating speed of the fan based on the target respiratory therapy control parameter and the current respiratory flow rate information to obtain the target rotating speed of the fan corresponding to the respiratory therapy equipment.

Step 210, controlling a fan of the respiratory therapy device based on the target fan speed.

The target fan rotating speed refers to the rotating speed when the fan is controlled to rotate. Specifically, the terminal calculates the fan rotation speed according to a preset fan rotation speed algorithm by using the target respiratory therapy control parameter and the current respiratory flow rate information to obtain the target fan rotation speed corresponding to the respiratory therapy equipment. And then the terminal can send the calculated fan rotating speed to a driving device corresponding to the fan, and the driving device controls the fan to move according to the target fan rotating speed, so that the fan carries out respiratory treatment on a user according to the gas conveyed by the target fan rotating speed.

According to the respiratory therapy equipment control method, by responding to the selection operation of the target respiratory therapy control option in the at least two respiratory therapy control options, the corresponding working mode can be started according to the requirements of a user, so that the seamless switching of the respiratory therapy modes in different therapy schemes is realized, and the equipment resources are saved. After the corresponding working mode is started, by calculating the error between the first respiratory pressure information and the second respiratory pressure information and then carrying out flow rate conversion, more accurate current respiratory flow rate information can be obtained quickly, and the error of single respiratory pressure information is avoided. And then, the fan rotating speed is rapidly calculated by using the target respiratory therapy control parameters and the current respiratory flow rate information, and the fan rotating speed is reached by controlling the movement of the fan, so that the operation parameters of the respiratory therapy equipment are controlled to meet the target respiratory therapy control parameters, and the control accuracy of the respiratory therapy equipment is improved.

In one embodiment, as shown in FIG. 3, a flow diagram is provided that is responsive to a secondary respiratory therapy control option; the target respiratory therapy control options comprise auxiliary respiratory therapy control options, and the target respiratory therapy control parameters corresponding to the auxiliary respiratory therapy control options comprise reference respiratory pressure parameters; step 208, calculating a fan rotation speed based on the target respiratory therapy control parameter information and the current respiratory flow rate information to obtain a target fan rotation speed corresponding to respiratory therapy equipment, including:

step 302, calculating a respiration variation baseline based on the current respiration flow rate information, and determining a current respiration state corresponding to the current respiration flow rate information by using the respiration variation baseline;

step 304, obtaining a current pressure parameter corresponding to a current respiratory state in the reference respiratory pressure parameters;

step 306, determining the target fan rotation speed corresponding to the current pressure parameter based on the preset mapping relation between the respiratory pressure parameter and the rotation speed.

The auxiliary respiratory therapy control options refer to options in respiratory therapy equipment capable of providing auxiliary respiratory therapy functions. The reference respiratory pressure parameter refers to a set parameter required for treatment with the auxiliary respiratory therapy function, and may represent a respiratory pressure parameter required for providing the respiratory environment to the user by the respiratory therapy device. The current respiratory flow rate information may be indicative of a user's respiratory state, including an expiratory state and an inspiratory state. The respiration transformation baseline represents a standard line for switching the expiration state and the inspiration state in the current respiration flow rate information and is used for judging the respiration state of the current user. The current breathing state refers to an exhalation state or an inhalation state that the user is in progress. The current pressure parameter refers to a reference respiratory pressure parameter that is required by the user at the current respiratory state. The preset mapping relation between the breathing pressure parameter and the rotating speed refers to a one-to-one mapping association relation between the breathing pressure parameter and the rotating speed which are preset.

Specifically, when the terminal detects that the target respiratory therapy control option is the auxiliary respiratory therapy control option, the terminal enters an auxiliary respiratory therapy control state. The auxiliary respiratory therapy function is realized under the auxiliary respiratory therapy control state, and can be used for carrying out auxiliary respiratory therapy by controlling respiratory pressure parameters so as to assist respiratory disease patients incapable of spontaneous breathing to breathe. The respiratory therapy apparatus may be used as a ventilator after entering a assisted respiratory therapy control state. And the terminal acquires the reference respiratory pressure parameter corresponding to the auxiliary respiratory therapy control option and acquires the current respiratory flow rate information.

The current respiration flow rate information of the user in the expiration state or the inspiration state is different, the terminal can convert the value of the corresponding current respiration flow rate information in the expiration state or the inspiration state into a flow rate curve, then a respiration change baseline is determined according to the change point in the flow rate curve, and the respiration change baseline can be a respiration change threshold of the respiration flow rate information. The terminal determines a current respiration state corresponding to the current respiration flow rate information by using the respiration change baseline, for example, the terminal acquires the current respiration flow rate information corresponding to the current moment, and when detecting that the value corresponding to the current respiration flow rate information exceeds a change threshold, the terminal indicates that the current respiration state corresponding to the current respiration flow rate information is an inhalation state; when the value corresponding to the current respiratory flow rate information is detected not to exceed the change threshold value, the current respiratory state corresponding to the current respiratory flow rate information is an expiration state.

And after the terminal determines the current respiratory state corresponding to the current respiratory flow rate information by using the respiratory variation baseline, determining the current pressure parameter corresponding to the current respiratory state in the reference respiratory pressure parameters. And then the terminal calls a preset mapping relation between the preset respiratory pressure parameter and the rotating speed, and searches the corresponding target fan rotating speed in the preset mapping relation between the respiratory pressure parameter and the rotating speed through the current pressure parameter. The terminal can detect whether the respiratory pressure parameter reaches the reference respiratory pressure parameter in real time, and convert the detected respiratory pressure parameter into a pressure parameter curve and display the pressure parameter curve.

In a specific embodiment, the fan is controlled to move in advance according to the minimum rotation speed to the maximum rotation speed, and under the condition of constant leakage flow rate, such as the leakage of a standard mask, the respiratory pressure parameters corresponding to different rotation speeds are collected at the tail end of a pipeline for conveying gas in real time, so that a one-to-one mapping relation between the respiratory pressure parameters and the rotation speed of the fan is generated.

In this embodiment, a respiration change baseline is calculated based on the current respiration flow rate information, and the current respiration state corresponding to the current respiration flow rate information can be rapidly determined according to the respiration change baseline, so as to obtain the current pressure parameter corresponding to the current respiration state in the reference respiration pressure parameters. The target fan rotating speed corresponding to the current pressure parameter can be obtained rapidly through the preset mapping relation between the respiratory pressure parameter and the rotating speed, so that the control efficiency of the respiratory treatment equipment is improved.

In one embodiment, step 302, calculating a breath variation baseline based on current breath flow information, comprises:

The normalization refers to a process of correcting a non-standard flow rate curve corresponding to current respiratory flow rate information into a standard flow rate curve. The standard flow rate curve refers to a normalized flow rate curve. The flow rate curve refers to a curve representing the breathing state of the user.

Specifically, when the flow velocity curve corresponding to the current respiratory flow velocity information is detected to be a non-standard flow velocity curve, for example, a flow velocity curve with unstable curve amplitude, unstable frequency and the like, the non-standard flow velocity curve is standardized, the non-standard flow velocity curve is corrected to be a flow velocity curve with a standard form, the terminal can be corrected by using a smooth filtering method to obtain a standard flow velocity curve, and the standard flow velocity curve can be a sine curve. When the flow velocity curve corresponding to the current respiratory flow velocity information is detected to be close to the standard flow velocity curve, the current respiratory flow velocity information is not standardized. And then the terminal acquires a peak value and a valley value corresponding to the standard flow rate curve, calculates the intermediate value of the peak value and the valley value to obtain a respiration change baseline, for example, calculates the average value of the peak value and the valley value to obtain the 0-axis of the sine wave, namely the respiration change baseline. Or calculating the difference between the absolute values of the peak value and the valley value, and dividing the difference by 2 to obtain the 0 axis of the sine wave, namely the respiratory variation baseline.

In one embodiment, as shown in FIG. 4, a schematic diagram of a standard flow rate profile is provided; the sine wave curve represents a standard flow rate curve; axis 0 represents respiratory change baseline; point a represents an exhalation trigger point, and point b represents an inhalation trigger point; the sine wave area above the 0 axis represents the inhalation state, and the sine wave area below the 0 axis represents the exhalation state.

In this embodiment, the accuracy of the breath change baseline can be improved by correcting the flow velocity curve corresponding to the current breath flow velocity information into the standard flow velocity curve and calculating the breath change baseline according to the standard flow velocity curve, thereby improving the accuracy of identifying the breath state.

In one embodiment, as shown in FIG. 5, a schematic flow diagram of a blow-by state process is provided; step 210, after controlling the fan corresponding to the respiratory treatment apparatus based on the target fan rotation speed, further includes:

step 502, when detecting that air leakage information exists, acquiring air leakage respiration flow rate information corresponding to the air leakage information;

step 504, calculating the rotating speed of the blower based on the target respiratory therapy control parameter and the air leakage respiratory flow rate information to obtain the rotating speed of the air leakage blower corresponding to the respiratory therapy equipment;

Step 506, controlling the fan of the respiratory therapy device based on the air leakage fan speed.

The air leakage information refers to information of abnormal air leakage of the mask. The blow-by respiratory flow rate information refers to respiratory flow rate information in the case of abnormal blow-by. The air leakage fan rotating speed refers to the fan rotating speed calculated under the abnormal air leakage condition.

In particular, respiratory therapy devices deliver gas to a mask to a user to enhance the respiratory environment, and the respiratory pressure parameter at the mask may decrease when an abnormal leak condition occurs at the mask in the respiratory therapy device. When the terminal can detect that the respiratory pressure parameter at the mask is reduced through the pressure sensor at the mask, or when the terminal detects that the respiratory pressure parameter at the mask is always smaller than the reference respiratory pressure parameter in a preset time period, the terminal judges that the mask is an abnormal air leakage result, for example, a user does not wear the mask correctly to cause abnormal air leakage, and the terminal takes the abnormal air leakage judgment result as air leakage information.

And when the terminal detects the air leakage information, acquiring the breathing pressure parameter of the mask under the abnormal air leakage condition, and then acquiring the breathing pressure parameter of the mask under the normal air leakage condition. The terminal calculates error information of the respiratory pressure parameter under the condition of normal air leakage and the respiratory pressure parameter under the condition of abnormal air leakage, and then the terminal can control the fan by using a preset pressure parameter adjustment algorithm, so that the respiratory pressure parameter at the mask is updated to the respiratory pressure parameter under the condition of normal air leakage. The terminal can also control the fan to gradually increase the rotating speed when detecting the air leakage information, and detect in real time through the pressure sensor at the face guard, stop controlling the fan to increase the rotating speed when detecting that the breathing pressure parameter at the face guard reaches the breathing pressure parameter under the condition of normal air leakage, and realize the breathing pressure parameter compensation at the face guard.

After the terminal detects that the respiratory pressure parameter at the mask reaches the respiratory pressure parameter under the condition of normal air leakage, the respiratory pressure information error corresponding to the air leakage information is calculated through the first pressure sensor and the second pressure sensor, and the flow rate conversion is carried out according to the respiratory pressure information error corresponding to the air leakage information, so that the air leakage respiratory flow rate information corresponding to the air leakage information is obtained.

The step that the terminal uses the target respiratory therapy control parameter and the air leakage respiratory flow rate information to calculate the fan rotating speed is the same as the step that the target respiratory therapy control parameter and the current respiratory flow rate information are used to calculate the fan rotating speed, which is not described in detail herein, then the terminal obtains the air leakage fan rotating speed corresponding to the respiratory therapy equipment, the terminal controls the fan of the respiratory therapy equipment according to the air leakage fan rotating speed, and the rotating speed of the fan is controlled to reach the air leakage fan rotating speed.

In this embodiment, when the air leakage information occurs, the respiratory pressure parameter at the mask is reduced, the pressure compensation at the mask is required to be achieved by increasing the rotational speed of the blower and increasing the flow rate of the air, and the flow rate of the user in the air suction state is also increased, so that the amplitude of the air suction curve in the sinusoidal flow rate curve corresponding to the air leakage respiratory flow rate information is increased, and therefore, the respiratory variation baseline in the sinusoidal flow rate curve corresponding to the air leakage respiratory flow rate information needs to be adjusted in real time again according to the values of the peak value and the valley value, thereby ensuring the accuracy of identifying the air suction and the air exhaust of the respiratory treatment device.

In one embodiment, as shown in fig. 6, a flow diagram is provided that is responsive to a flow respiratory therapy control option; the target respiratory therapy control options comprise flow respiratory therapy control options, and the target respiratory therapy control parameters corresponding to the flow respiratory therapy control options comprise reference oxygen concentration parameters and reference respiratory flow rate parameters; step 208, calculating a fan rotation speed based on the target respiratory therapy control parameter information and the current respiratory flow rate information to obtain a target fan rotation speed corresponding to respiratory therapy equipment, including:

step 602, performing flow rate distribution calculation on the gas of the respiratory therapy equipment based on the reference oxygen concentration information and the reference respiratory flow rate information to obtain gas flow rate distribution information of the respiratory therapy equipment;

step 604, determining a target fan rotation speed corresponding to the gas flow rate distribution information based on a preset mapping relation between the gas flow rate and the rotation speed, wherein the target fan rotation speed is used for updating the current respiration flow rate information to obtain the gas flow rate distribution information.

The preset mapping relation between the gas flow rate and the rotating speed refers to a one-to-one mapping association relation between the preset gas flow rate and the rotating speed.

Specifically, when the terminal detects that the target respiratory therapy control option is the flow respiratory therapy control option, the terminal enters a flow respiratory therapy control state. The flow respiratory therapy function is realized under the flow respiratory therapy control state, and can be used for carrying out respiratory therapy by controlling the gas flow, and carrying out oxygen supply therapy on patients suffering from mild-moderate hypoxia. The respiratory therapy apparatus may be used as a high flow respiratory therapy apparatus after entering a flow respiratory therapy control state. The terminal acquires a reference oxygen concentration parameter and a reference respiratory flow rate parameter corresponding to the auxiliary respiratory therapy control options.

And then the terminal performs flow rate distribution calculation on different input gases in the respiratory treatment equipment according to the reference oxygen concentration parameter and the reference respiratory flow rate parameter, so as to obtain flow rate information corresponding to different conveying gases by calculation, and obtain gas flow rate distribution information. And then the terminal acquires a preset mapping relation between the preset gas flow rate and the rotating speed, and searches the corresponding target fan rotating speed in the preset mapping relation between the gas flow rate and the rotating speed through the gas flow rate distribution information. The terminal controls the wind to move according to the target fan rotating speed, so that the rotating speed of the fan reaches the target fan rotating speed, and the current breathing flow rate information corresponding to the gas conveyed during the movement of the fan is updated into gas flow rate distribution information. The terminal can detect whether the flow velocity information of the input gas reaches the reference respiratory flow velocity parameter in real time, and convert the flow velocity information of the input gas into a corresponding flow velocity curve and display the flow velocity curve.

In a specific embodiment, the fan is controlled to move in advance from the minimum rotation speed to the maximum rotation speed, and under the condition of constant leakage flow rate, such as the leakage of a standard mask, the gas flow rates corresponding to different rotation speeds are collected at the tail end of a pipeline for conveying the gas in real time, so that a one-to-one mapping relation between the gas flow rates and the rotation speed of the fan is generated.

In this embodiment, the terminal performs flow rate distribution calculation on the gas of the respiratory therapy device according to the reference oxygen concentration information and the reference respiratory flow rate information, so that the gas flow rate distribution information can be obtained quickly, and then the terminal determines the target fan rotation speed corresponding to the gas flow rate distribution information by using the preset mapping relation between the gas flow rate and the rotation speed, so that the fan is controlled to move in quick response to the obtained target fan rotation speed, the gas conveyed by the fan according to the target fan rotation speed reaches the reference oxygen concentration parameter and the reference respiratory flow rate parameter, and the control efficiency of the respiratory therapy device is improved.

The parameter unit of the reference respiratory flow rate information may be ml/min (milliliter/min), which indicates the content of the mixed gas in a unit time, for example, 100ml/min indicates that the content of the mixed gas in 1min is 100ml. The reference oxygen concentration information refers to the ratio of the oxygen content in the mixed gas to the mixed gas content.

Specifically, the terminal performs product calculation on the reference oxygen concentration information and the reference respiratory flow rate information to obtain oxygen content corresponding to the reference respiratory flow rate information, and the oxygen content in the mixed gas is represented. And the terminal calculates the difference value between the content of the mixed gas and the content of oxygen in the reference respiratory flow rate information to obtain the target non-oxygen content corresponding to the reference respiratory flow rate information, and the target non-oxygen content represents the content of the non-oxygen gas in the mixed gas. Since the oxygen flow rate information corresponds to pure oxygen, the non-oxygen gas in the mixed gas corresponding to the reference respiratory flow rate information is derived from the air corresponding to the air flow rate information. The ratio of the oxygen content and the ratio of the non-oxygen content in the air can be obtained through the ratio of the air component content. The relation expression of the air flow rate and the non-oxygen content can be generated through the non-oxygen content proportion, the non-oxygen content and the air flow rate information in the air. The air flow rate and non-oxygen content relationship expression can be stored in the storage space in advance by manpower for subsequent use.

And after the terminal calculates the target non-oxygen content, calling a preset relational expression of the air flow rate and the non-oxygen content to calculate the target non-oxygen content, so as to obtain air flow rate information. And then the terminal obtains oxygen flow rate information according to the preset association relation between the air flow rate information, the oxygen flow rate information and the reference respiratory flow rate information. The preset association of the air flow rate information, the oxygen flow rate information and the reference respiratory flow rate information may indicate that the sum including the air flow rate information and the oxygen flow rate information is equal to the reference respiratory flow rate information.

In one embodiment, the terminal may use the air flow rate information and the oxygen flow rate information as unknown calculation parameters. The terminal then takes the air composition ratio, wherein nitrogen (N ₂ ) About 78.1% of oxygen (O) ₂ ) About 20.9% and rare gases about 0.939%, so that an oxygen content of 20.9% and a non-oxygen content of 79.1% in air can be obtained. Then within a unit time, the following relationship exists:

the relational expression of the reference respiratory flow rate information and the reference oxygen concentration information is:

reference respiratory flow rate information reference oxygen concentration information = oxygen content in the mixed gas;

the relational expression concerning the oxygen content in the mixed gas is:

air flow rate information 20.9% + oxygen flow rate information 100% = oxygen content in the mixed gas;

the preset association relationship between the air flow rate information, the oxygen flow rate information and the reference respiratory flow rate information is as follows:

air flow rate information+oxygen flow rate information=reference respiratory flow rate information (mixed gas content).

The relation expression of the air flow rate and the non-oxygen content obtained after conversion is as follows: air flow information = target non-oxygen content/79.1%. And after the terminal calculates the air flow rate information by using the relational expression of the air flow rate and the non-oxygen content, obtaining the oxygen flow rate information by using the preset association relation of the air flow rate information, the oxygen flow rate information and the reference respiratory flow rate information. For example, if the reference respiratory flow rate information is 100ml/min and the reference oxygen concentration information is 50%, the mixed gas content in the reference respiratory flow rate information can be obtained in a unit time to be 100ml, and the oxygen content in the mixed gas is 100×50% =50 ml. Taking the air flow rate information as an unknown calculation parameter A and the oxygen flow rate information as an unknown calculation parameter B, the association relationship is as follows:

A*20.9％+B*100％＝50ml；

A+B＝100ml；

Specific values of the air flow rate information and the oxygen flow rate information can be obtained through calculation.

In one embodiment, the terminal calculates the gas flow rate distribution information, which includes air flow rate information and oxygen flow rate information. The terminal opens the oxygen valve according to different opening degrees after obtaining the oxygen flow rate information, and oxygen is conveyed through the oxygen valve, then the pressure difference acquired through the first pressure sensor and the second pressure sensor is converted into the current flow rate of conveying the oxygen, and when detecting that the current flow rate of conveying the oxygen reaches the oxygen flow rate information, the current opening degree of the oxygen valve is maintained. And then the terminal searches the corresponding target fan rotating speed in the preset mapping relation between the air flow speed and the rotating speed according to the air flow speed information, opens the air inlet, controls the fan to move according to the target fan rotating speed to convey air, converts the pressure difference acquired by the first pressure sensor and the second pressure sensor into the current flow speed of the conveyed air, and detects whether the current flow speed of the conveyed air reaches the air flow speed information.

In this embodiment, by performing flow rate distribution calculation to obtain air flow rate information and oxygen flow rate information, an air flow rate value and an oxygen flow rate value that need to be input can be obtained. Then, the opening of the oxygen valve is controlled according to the oxygen flow velocity value to input the required oxygen flow velocity value, single accurate output can be realized, and the oxygen valve does not need to be regulated in real time. And the fan is controlled according to the target fan rotating speed obtained by the air flow velocity value, so that the control efficiency of the fan and the oxygen valve is improved.

And then the oxygen generating equipment inputs the dried gas into a molecular tower to adsorb nitrogen, discharges non-adsorbed oxygen in the adsorption process, and releases the nitrogen just adsorbed after the oxygen is conveyed to a storage tank, the oxygen generating equipment controls the molecular tower to alternately and circularly operate left and right towers to circularly manufacture more oxygen, and the oxygen is conveyed through an oxygen valve in response to an oxygen generating instruction, so that the conveyed oxygen is mixed with air, and the mixed gas conforming to the reference oxygen concentration information and the reference breathing flow rate information is obtained.

In a specific embodiment, when the terminal detects that the respiration flow rate information and the oxygen concentration information of the conveyed mixed gas accord with the reference oxygen concentration information and the reference respiration flow rate information, or the terminal detects that the respiration pressure parameter of the conveyed auxiliary respiration gas accords with the reference respiration pressure parameter, the temperature and the humidity of the conveyed gas are detected by the temperature and humidity sensor. When the temperature of the conveyed gas is detected to be smaller than the set temperature, a heating instruction is sent to heating equipment, the heating equipment responds to the heating instruction to heat the pipeline for conveying the gas, and meanwhile, the water tank of the pipeline for conveying the gas is heated. Different temperatures can correspond to different humidities, different evaporation amounts are controlled through different heating amounts of the water tank according to different temperatures, gas at the tail end of a pipeline for conveying gas reaches the optimal relative humidity of a human body, and the terminal monitors whether the gas temperature at the tail end reaches the set gas temperature in real time. In this embodiment, the heating amount of the water temperature is determined according to the tolerance degree and the comfort degree of the human body to different humidities under different temperature conditions, so that the heating efficiency of the gas is improved.
