[0023] It should be noted that the pressure control method of the micro-pressure oxygen chamber is applied to medical equipment or health care products, which helps to increase the solubility of oxygen in the blood and promote oxygen to be absorbed by tissues more effectively. It can achieve precise pressure control and ensure that the pressure fluctuation is within a certain range.

[0024] The technical solution provided in the embodiments of the present application is further described below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 , Figure 1 It is a flow chart of the pressure control method of the microcompression oxygen chamber provided in the embodiment of the present application. The pressure control method of the microcompression oxygen chamber is applied to the controller of the intelligent control system, and the intelligent control system also includes a pressure detection device, an oxygen regulating device and a variable frequency scroll compressor, the variable frequency scroll compressor is respectively connected to the oxygen regulating device, the pressure detection device, and the controller, the oxygen regulating device and the pressure detection device are respectively connected to the controller, the controller includes a pressure control device of the microcompression oxygen chamber, and the pressure control method of the microcompression oxygen chamber is executed by a processor in an electronic device or a readable storage medium, and the pressure control method of the microcompression oxygen chamber includes steps S100, step S200, step S300, step S400, step S500 and step S600.

[0026] Step S100, obtaining the current air pressure value of the detected micro-pressure oxygen chamber from the pressure detection device.

[0027] In one embodiment, the current air pressure value is the pressure value in the micro-compression oxygen chamber at the current moment. By arranging multiple pressure sensors in the micro-compression oxygen chamber, the pressure sensors communicate with the pressure detection device, and the controller obtains the current air pressure value of the micro-compression oxygen chamber detected by the pressure detection device, so that the pressure state in the micro-compression oxygen chamber can be detected at any time or in time to prepare for subsequent pressure adjustment.

[0028] Step S200, obtaining the adjusted target air pressure value.

[0029] In one embodiment, the target air pressure value is the air pressure value corresponding to the actual required oxygen content. According to the demand, the adjusted target air pressure value can be obtained by the user inputting the pressure value and using a preset interface to obtain the input value; or it can be based on the oxygen content corresponding to the current air pressure value, and the pressure value is predicted by a preset prediction algorithm to obtain the adjusted pressure value, so that the solubility of oxygen is higher. Among them, the preset prediction algorithm can be a trained machine learning algorithm or a deep learning algorithm, and the specific training process is not described here. By obtaining the target air pressure value, it is beneficial to have a subsequent adjustment reference value and pressure regulation.

[0030] Step S300, obtaining an adjustment range according to the current air pressure value and a preset air pressure fluctuation value.

[0031] In one embodiment, in order to ensure that the air pressure is within a specific fluctuation range, in addition to setting a variable frequency scroll compressor, an adjustment range is also set. The preset air pressure fluctuation value is the value that the pressure fluctuation cannot exceed when the pressure of the set micro-pressure oxygen chamber is adjusted. It can be set to 1kpa or 2kpa. The adjustment range is calculated based on the current air pressure value obtained and the preset air pressure fluctuation value to avoid the gear or range of the adjustment being limited, and the pressure can be adjusted within a certain range without being restricted by the gear.

[0032] like Figure 2 As shown, according to the current air pressure value and the preset air pressure fluctuation value, the adjustment range is obtained, including but not limited to the following steps: Step S310, calculating the difference between the current air pressure value and the air pressure fluctuation value to obtain a first end value.

[0033] In some possible embodiments of the present application, the pressure difference is obtained by subtracting the pressure fluctuation value from the current pressure value, and when the pressure difference is greater than 0, the pressure difference is used as the first end value. When the pressure difference is less than 0, the absolute value of the pressure difference is taken, and the absolute value of the obtained pressure difference is used as the first end value, so as to obtain the adjustment range later.

[0034] Step S320, calculating the sum of the current air pressure value and the air pressure fluctuation value to obtain a second end value.

[0035] In some possible embodiments of the present application, since the current air pressure value and the air pressure fluctuation value are both greater than 0, the current air pressure value and the air pressure fluctuation value are added to obtain the second end value, so as to subsequently obtain the adjustment range.

[0036] Step S330, obtaining an adjustment range according to the first end value and the second end value.

[0037] In some possible embodiments of the present application, the first end value is used as the lower limit of the adjustment range, and the second end value is used as the upper limit of the adjustment range to obtain the adjustment range, thereby avoiding limited adjustment gear or range, and being able to adjust the pressure within a certain range without being restricted by the gear.

[0038] In some other possible embodiments of the present application, the difference between the current air pressure value and the air pressure fluctuation value can be calculated to obtain the second end value, and the sum of the current air pressure value and the air pressure fluctuation value can be calculated to obtain the first end value. The first end value is used as the upper limit of the adjustment range, and the second end value is used as the lower limit of the adjustment range to obtain the adjustment range, thereby avoiding limited adjustment gears or ranges, and being able to adjust the pressure within a certain range without being restricted by gears.

[0039] Step S400, determine whether the target air pressure value is within the adjustment range. If it is not within the adjustment range, obtain the adjustment times and the adjustment pressure values ​​corresponding to each adjustment times according to the target air pressure value, the air pressure fluctuation value, the current air pressure value and the adjustment range.

[0040] In one embodiment, according to the adjustment range obtained in step S300, if the target air pressure value is within the adjustment range, it is proved that the pressure adjustment fluctuation is within the preset range, and if the target air pressure value is not within the adjustment range, it is proved that the pressure adjustment fluctuation exceeds the preset range once, and multiple adjustments are required to achieve accurate adjustment. First, it is determined whether the target air pressure value is within the adjustment range. If it is not within the adjustment range, the number of multiple adjustments and the adjustment value are calculated. According to the target air pressure value, the air pressure fluctuation value, the current air pressure value and the adjustment range, the number of adjustments and the adjustment air pressure values ​​corresponding to each adjustment number are obtained, so that subsequent adjustments are made according to the number of adjustments and the adjustment air pressure values ​​to achieve accurate pressure adjustment.

[0041] like Figure 3 As shown, according to the target air pressure value, the air pressure fluctuation value, the current air pressure value and the adjustment range, the adjustment times and the adjustment air pressure values ​​corresponding to each adjustment times are obtained, including but not limited to the following steps: Step S410, calculating the air pressure difference value according to the current air pressure value and the target air pressure value.

[0042] In some possible embodiments of the present application, the current air pressure value is subtracted from the target air pressure value to obtain the regulated pressure difference value, and when the regulated pressure difference value is greater than 0, the regulated pressure difference value is used as the air pressure difference value. When the regulated pressure difference value is less than 0, the absolute value of the regulated pressure difference value is taken, and the absolute value of the regulated pressure difference value is used as the air pressure difference value, so as to subsequently calculate the number of adjustments and the regulated air pressure value according to the air pressure difference value.

[0043] Step S420, dividing the air pressure difference by the air pressure fluctuation value to obtain a quotient and a remainder.

[0044] In some possible embodiments of the present application, the pressure difference is divided by the pressure fluctuation value to obtain a quotient and a remainder, so that the number of adjustments and the adjusted pressure value corresponding to each adjustment number can be determined based on the quotient and the remainder.

[0045] Step S430, when the remainder is 0, the quotient value is used as the adjustment number, and the air pressure fluctuation value is used as the adjustment air pressure value corresponding to each adjustment number.

[0046] In some possible embodiments of the present application, when the remainder is 0, it indicates that the pressure difference is just an integer multiple of the pressure fluctuation value, and the same pressure value can be adjusted each time. The quotient value is used as the number of adjustments, and in each adjustment, the pressure fluctuation value is used as the adjustment pressure value corresponding to each adjustment number, which can ensure that the working pressure fluctuation in the micro-pressure oxygen chamber does not exceed the set pressure fluctuation value, perform precise pressure control, and realize pressure adjustment of multiple different gears, so that the working pressure can be infinitely adjustable.

[0047] For example, when the remainder is 0, the value of the quotient can be 1. A quotient value of 1 indicates that only one adjustment is required. When the quotient value is 2, it indicates that two adjustments are required, and the adjusted air pressure value of each adjustment is the same as the air pressure fluctuation value, so that the maximum working pressure fluctuation in the micro-pressure oxygen chamber does not exceed the set air pressure fluctuation value, thereby achieving precise pressure control.

[0048] It should be noted that, according to the sign of the pressure difference, the pressure adjustment value is also marked with the sign. When the pressure value in the micro-compression oxygen chamber is large and needs to be reduced, the sign of the pressure adjustment value is negative, and the sign is used as a mark of pressure reduction, and its value is used as the pressure value to be adjusted. When the pressure value in the micro-compression oxygen chamber is large and needs to be increased, the sign of the pressure adjustment value is positive, as a mark of pressure increase, and its value is used as the pressure value to be adjusted.

[0049] like Figure 3 As shown, after the pressure difference is divided by the pressure fluctuation value to obtain the quotient and remainder, the pressure control method of the micro-pressure oxygen chamber also includes but is not limited to the following steps: Step S440, when the remainder is not 0, the result of adding 1 to the quotient is used as the adjustment number, in the adjustment number corresponding to the quotient, the air pressure fluctuation value is used as the adjustment air pressure value corresponding to the adjustment number, and in the adjustment number corresponding to the remainder, the remainder is used as the adjustment air pressure value.

[0050] In some possible embodiments of the present application, when the remainder is 0, it indicates that the air pressure difference is not an integer multiple of the air pressure fluctuation value, and the air pressure value adjusted each time may be different. At this time, the value of the quotient is added by 1 as the number of adjustments to ensure that the target air pressure value can be accurately adjusted. When the number of adjustments corresponds to the quotient value, the air pressure fluctuation value is used as the adjusted air pressure value corresponding to each adjustment number each time. At the last adjustment number, the remainder is used as the adjusted air pressure value, which can meet the requirement that the working pressure fluctuation in the micro-pressure oxygen chamber does not exceed the set air pressure fluctuation value, and can perform precise pressure control, and can realize pressure adjustment of multiple different gears, and realize infinitely adjustable working pressure.

[0051] In one embodiment, after determining whether the target air pressure value is within the adjustment range, the pressure control method of the micro-pressure oxygen chamber further includes but is not limited to the following steps: Step S700, when it is within the adjustment range, determine that the number of adjustments is one, and obtain the adjustment air pressure value according to the target air pressure value and the current air pressure value, and execute the step of obtaining the adjustment speed according to the number of adjustments and the adjustment air pressure value.

[0052] In one embodiment, according to the adjustment range obtained in step S300, if the target air pressure value is within the adjustment range, it is proved that the pressure adjustment fluctuation is within the preset range, and it is judged whether the target air pressure value is within the adjustment range. If it is within the adjustment range, it indicates that the current adjustment air pressure value will not exceed the working fluctuation range in the micro-compression oxygen chamber, and there is no need to make multiple adjustments, and the number of adjustments is determined to be one. Within this number of adjustments, the target air pressure value is subtracted from the current air pressure value to obtain the adjustment air pressure value, and then the step of obtaining the adjustment speed according to the number of adjustments and the adjustment air pressure value is performed to adjust the working pressure in the micro-compression oxygen chamber, which can realize pressure adjustment of multiple different gears and realize infinitely adjustable working pressure.

[0053] It should be noted that the adjusted air pressure value obtained by subtracting the current air pressure value from the target air pressure value may be negative. For example, when the pressure value in the micro-pressure oxygen chamber is large and needs to be reduced, the target air pressure value is less than the current air pressure value. At this time, the adjusted air pressure value is a negative value, and the sign is used as an indicator of reducing pressure, and its value is used as the air pressure value that needs to be adjusted. When the target air pressure value is greater than the current air pressure value, the sign is positive, which is used as an indicator of increasing pressure, and its value is used as the air pressure value that needs to be adjusted.

[0054] Step S500, obtaining the adjustment speed according to the adjustment times and the adjustment air pressure value.

[0055] like Figure 4 As shown, according to the adjustment times and the adjustment air pressure value, the adjustment speed is obtained, including but not limited to the following steps: In one embodiment, the pressure difference and the number of adjustments are input into a preset adjustment algorithm, which can be a machine learning model or a deep learning model. The deep learning model is used as an example for explanation. The adjustment algorithm includes an input layer, a hidden layer, and an output layer. The processing steps of the adjustment algorithm are: Step S510, input the air pressure difference and the number of adjustments into the input layer, and output the air pressure feature vector corresponding to the air pressure difference and the adjustment feature vector corresponding to the number of adjustments.

[0056] In some possible embodiments of the present application, the air pressure difference and the number of adjustments are input into the input layer for feature vector conversion to obtain the air pressure feature vector corresponding to the air pressure difference and the adjustment feature vector corresponding to the number of adjustments, so that the subsequent hidden layer can extract features from the air pressure feature vector and the adjustment feature vector. It should be noted that before the air pressure difference and the number of adjustments are input into the input layer, the air pressure difference and the number of adjustments can also be processed, illustratively, data normalization and other processing are performed, which will not be described in detail here.

[0057] Step S520, using the hidden layer to extract the pressure feature vector and the adjustment feature vector to obtain the intermediate feature vector, the hidden layer has multiple layers, each hidden layer is provided with 256 neurons, and non-adjacent hidden layers are connected to transmit the features of the previous hidden layer to the lower layer.

[0058] In some possible embodiments of the present application, the adjustment algorithm sets multiple hidden layers, and each hidden layer is provided with 256 neurons. Setting the above number of neurons can ensure the full extraction of features, and can also reduce network parameters, thereby reducing network complexity. Then, the non-adjacent hidden layers are connected to transmit the features of the previous hidden layer to the lower layer, that is, the previous hidden layer is not only connected to the next hidden layer, but also to the next hidden layer, which can avoid the disappearance of the gradient in the network calculation process, and is conducive to the full fusion of features and improves the ability to express features. By using each hidden layer to extract features from the air pressure feature vector and the adjustment feature vector, an intermediate feature vector is obtained, which can accurately express features, and is conducive to the subsequent prediction of the rotation speed, thereby achieving accurate pressure regulation.

[0059] Step S530: perform feature linear processing on the intermediate feature vector using the output layer, and output the adjusted speed.

[0060] In some possible embodiments of the present application, the output layer is finally used to perform feature linear processing on the intermediate feature vector, extract high-dimensional features of the data, enhance the expressiveness of the data, and output the adjusted speed. By utilizing the adjustment algorithm, a more accurate adjusted speed can be predicted so that the adjusted speed can be used to subsequently drive the variable frequency scroll compressor.

[0061] Step S600, driving the variable frequency scroll compressor according to the adjusted air pressure value and the adjusted speed, so as to drive the oxygen regulating device to inject gas into the micro-compression oxygen chamber or extract gas from the micro-compression oxygen chamber, so that the pressure value of the micro-compression oxygen chamber fluctuates within a preset fluctuation range.

[0062] In one embodiment, the variable frequency scroll compressor is a variable frequency scroll oil-free compressor, which can provide a stable oxygen supply for the micro-pressure oxygen chamber and help adjust the air pressure in the chamber to meet different adjustment requirements. The sign of the pressure value can determine the direction of adjustment, and the speed can adjust the frequency of the variable frequency scroll oil-free compressor, thereby driving the variable frequency scroll oil-free compressor to achieve precise adjustment.
