Description

Technical Field

[0001] The present invention relates to the technical field of outdoor emergency oxygen supply, and in particular, to a shared self-service liquid oxygen supply monitoring system and method, and a mobile oxygen supplementation device. Background Art

[0002] Currently, in scenarios such as medical first aid and outdoor travel, the demand for oxygen is increasing day by day. Especially in scenarios such as plateau tourism, hypoxia symptoms such as insufficient oxygen supply and too low blood oxygen saturation are likely to occur. There are many problems with traditional oxygen supply means. For example, some fixed oxygen inhalation devices require users to stay in a specific place, which hinders the travel and activities of users, and the convenience during use is poor, reducing the willingness of users to use.

[0003] At the same time, with the development and progress of technology and the improvement of people's living standards, the demand for more convenient oxygen supply services is constantly increasing. The rise of the sharing economy model enables people to use various shared devices anytime and anywhere through simple operations such as scanning codes and swiping cards, meeting people's demand for convenience, and improving the utilization efficiency of oxygen inhalation devices, indirectly reducing the idle waste of resources.

[0004] In the prior art, when a shared oxygen inhalation device is returned, it is usually necessary to monitor the change in the internal liquid oxygen level of the oxygen inhalation device by means of a liquid level sensor or a weight sensor to assist in usage billing. However, since the environment that requires outdoor oxygen supply is usually in a plateau area, the overall terrain is relatively rugged and the environmental temperature is low. Therefore, improper use or temperature influence is likely to cause damage or aging of the equipment valve, resulting in liquid oxygen gasification leakage. Currently, the current oxygen inhalation devices generally do not have a leakage detection function when returned or stationary, which may lead to oxygen consumption during subsequent use by users and an increase in the overall use risk; at the same time, the monitoring sensor will have voltage attenuation during long-term operation. Especially in a low-temperature environment such as a plateau, the performance of the sensor is more affected by temperature, which is likely to lead to inaccurate monitoring of the liquid level and usage status of the returned equipment. Moreover, the performance attenuation of the above sensors is usually difficult to detect in time, further affecting the monitoring accuracy. Summary of the Invention

[0005] Therefore, the present invention provides a shared self-service liquid oxygen supply monitoring system and method, and a mobile oxygen supplementation device to solve the technical problems in the prior art that it is difficult to detect air leakage in a shared self-service oxygen supply oxygen inhalation device, and the monitoring sensor is prone to performance attenuation and difficult to detect and adjust in time.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A shared self-service liquid oxygen supply monitoring method, including the following steps:

[0008] Construct a leakage state monitoring, liquid level monitoring and monitoring performance calibration function architecture for mobile oxygen inhalation devices;

[0009] Based on the monitoring and calibration function architecture, the mobile oxygen inhalation devices placed correspondingly form a closed vacuum comparison cavity and a closed variable pressure monitoring cavity respectively;

[0010] Calculate the actual weighing data of the mobile oxygen inhalation device, and further convert it based on the actual weighing data of the mobile oxygen inhalation device to obtain its internal liquid level state, so as to complete the liquid level monitoring process;

[0011] Obtain the real-time internal pressure of the closed vacuum comparison cavity through the monitoring and calibration function architecture as the initial internal pressure of the architecture, and obtain the real-time internal pressure of the closed variable pressure monitoring cavity corresponding to different time axis nodes;

[0012] Compare the real-time internal pressures of the obtained closed variable pressure monitoring cavity corresponding to different time axis nodes, and judge the leakage state of the mobile oxygen inhalation device according to the internal pressure comparison result.

[0013] On the basis of the above technical solution, the present invention is further described as follows:

[0014] As a further solution of the present invention, the construction of the leakage state monitoring, liquid level monitoring and monitoring performance calibration function architecture for mobile oxygen inhalation devices specifically includes: setting a monitoring chamber structure, and setting a pick-up and placement channel communicating with its inner cavity at the top of the monitoring chamber structure and a pressing cover body detachably and hermetically assembled with the pick-up and placement channel, and arranging a lifting drive structure on the back side of the monitoring chamber structure which is drivingly assembled and connected with the pressing cover body;

[0015] Continuing, a number of groups of directional guide plates are fixedly arranged corresponding to the inner cavity of the monitoring chamber structure, and a number of groups of sensing weighing platforms are fixedly arranged at the bottom of the inner cavity of the monitoring chamber structure, and a ring-shaped flexible bottom bearing seat is commonly positioned at the outer edge top corresponding to a number of groups of the sensing weighing platforms, and the flexible bottom bearing seat is correspondingly arranged with the guiding positions formed by a number of groups of the directional guide plates, so as to accurately position and assist in hermetically supporting the bottom end of the mobile oxygen inhalation device through the flexible bottom bearing seat; At this time, the outer side of the mobile oxygen inhalation device and the flexible bottom bearing seat in the inner cavity of the monitoring chamber structure forms a closed variable pressure monitoring cavity, and the inner side of the mobile oxygen inhalation device and the flexible bottom bearing seat forms a closed vacuum comparison cavity;

[0016] A vacuum monitoring sensor and a vacuum suction valve body are respectively arranged corresponding to the closed vacuum comparison cavity, and a pressurizing blowing valve body, a variable pressure monitoring sensor and a recovery suction valve body are arranged corresponding to the closed variable pressure monitoring cavity;

[0017] The electronic control module is electrically connected to the lifting drive structure, the vacuum monitoring sensor, the vacuum suction valve body, the pressurized blowing valve body, the variable pressure monitoring sensor, and the recovery suction valve body through circuits.

[0018] As a further solution of the present invention,

[0019] The mobile oxygen inhalation devices placed corresponding to the monitoring and calibration function architecture respectively form a closed vacuum comparison chamber and a closed variable pressure monitoring chamber, specifically including:

[0020] Control the start of the lifting drive structure to output kinetic energy to lift the pressure cover body to open the access channel;

[0021] Place the mobile oxygen inhalation device into the inner cavity of the monitoring chamber structure through the access channel, and shift it along the directional guide plate until it is in a closed contact with the flexible bottom support on the top of several groups of sensing weighing platforms, so that the mobile oxygen inhalation device forms a closed vacuum comparison chamber corresponding to the inner side of the flexible bottom support;

[0022] At this time, the total gravity G1 of the initially placed mobile oxygen inhalation device and the flexible bottom support is obtained in real time through several groups of sensing weighing platforms, where the preset gravity of the flexible bottom support is G0;

[0023] Continue to control the drive to press the cover body to seal the access channel, so that the inner cavity of the monitoring chamber structure forms a closed variable pressure monitoring chamber corresponding to the outer sides of the mobile oxygen inhalation device and the flexible bottom support;

[0024] The actual weighing data of the mobile oxygen inhalation device is calculated, and the internal liquid level state is further converted based on the actual weighing data of the mobile oxygen inhalation device to complete the liquid level monitoring process, specifically including:

[0025] According to the obtained total gravity G1 of the initially placed mobile oxygen inhalation device and the flexible bottom support, calculate the current actual gravity G2 of the initially placed mobile oxygen inhalation device. The specific calculation formula is:

[0026] G2 = G1 - G0 (1)

[0027] In the formula, G0 is the preset gravity value of the flexible bottom support;

[0028] After that, based on the current actual gravity G2 of the mobile oxygen inhalation device, further convert it through a conversion coefficient to obtain the liquid level value of the mobile oxygen inhalation device at the initial placement to complete the liquid level monitoring process.

[0029] As a further solution of the present invention,

[0030] The real-time internal pressure of the closed vacuum comparison chamber is obtained through the monitoring and calibration function architecture as the initial internal pressure of the architecture, and the real-time internal pressures of the closed variable pressure monitoring chamber corresponding to different time axis nodes are obtained, specifically including:

[0031] Obtain the real-time internal pressure P of the closed variable-pressure monitoring cavity corresponding to the first node t1 of the current time axis through the variable-pressure monitoring sensor in the monitoring and calibration function architecture m1 , and obtain the real-time internal pressure P of the closed vacuum comparison cavity corresponding to the first node t1 of the current time axis through the vacuum monitoring sensor n . At this time, since the closed vacuum comparison cavity is closed immediately after the mobile oxygen inhalation device is initially placed, the internal pressure P of the closed vacuum comparison cavity n is used as the initial internal pressure P formed in the inner cavity of the monitoring chamber structure after the placement process n ;

[0032] Continue to obtain the real-time internal pressure P of the closed variable-pressure monitoring cavity corresponding to the second node t2 of the current time axis through the variable-pressure monitoring sensor in the monitoring and calibration function architecture m2 .

[0033] As a further solution of the present invention,

[0034] Compare the real-time internal pressures of the obtained closed variable-pressure monitoring cavity corresponding to different time axis nodes, and judge the air leakage state of the mobile oxygen inhalation device according to the internal pressure comparison result, specifically including:

[0035] Compare the real-time internal pressure values of the obtained closed variable-pressure monitoring cavity corresponding to the first node t1 and the second node t2 of the current time axis, specifically as follows:

[0036] If P m2 =P m1 =P n , it proves that the internal pressure in the closed variable-pressure monitoring cavity from the first node t1 to the second node t2 of the current time axis has not increased, and at this time the mobile oxygen inhalation device is not in a leaking state;

[0037] If P m2 >P m1 , it proves that the internal pressure in the closed variable-pressure monitoring cavity from the first node t1 to the second node t2 of the current time axis has increased, and at this time the mobile oxygen inhalation device is in a leaking state.

[0038] As a further solution of the present invention, it also includes:

[0039] When the mobile oxygen inhalation device is in a leaking state, control the monitoring and calibration function architecture to pressurize the closed variable-pressure monitoring cavity until the pressure at the leakage point is balanced and the air leakage stops;

[0040] Continue to cooperate with the gravity change value formed by the pressurization of the closed variable-pressure monitoring cavity and the air leakage state corresponding to the mobile oxygen inhalation device to verify the monitoring performance of the monitoring and calibration function architecture.

[0041] As a further solution of the present invention,

[0042] When the mobile oxygen inhalation device is in a leaky state, the control monitoring and calibration function architecture corresponds to pressurizing the closed variable pressure monitoring chamber until the pressure at the leakage point is balanced and the air leakage stops. Specifically, it includes:

[0043] Through the cooperation of the pressurizing and blowing valve body and the variable pressure monitoring sensor in the monitoring and calibration function architecture, oxygen is input into the closed variable pressure monitoring chamber from the second node t2 of the time axis to pressurize the inside of the closed variable pressure monitoring chamber. The variable pressure monitoring sensor is used to monitor and record the current internal pressure increase speed value of the closed variable pressure monitoring chamber in real time, as the total internal pressure increase speed R corresponding to pressurization and air leakage m ;

[0044] During the gradual pressurization process inside the closed variable pressure monitoring chamber, the air leakage volume at the leakage point of the mobile oxygen inhalation device gradually decreases under the action of external pressure. At this time, the internal pressure increase speed corresponding to air leakage decreases synchronously. When the internal pressure increase speed R corresponding to pressurization a is preset to be unchanged, the total internal pressure increase speed R m then decreases synchronously;

[0045] Continue to monitor and record the total internal pressure increase speed R of the closed variable pressure monitoring chamber m , when reaching the third node t3 of the time axis, when the total internal pressure increase speed R m no longer decreases but maintains a constant value within the preset threshold range, then immediately stop continuing to pressurize. At this time, the internal pressure increase speed corresponding to air leakage is 0, and the finally monitored total internal pressure increase speed R m is the preset internal pressure increase speed R corresponding to pressurization a , thus completing the pressure balance regulation for the leakage point position of the mobile oxygen inhalation device, preventing waste and safety hazards caused by continuous oxygen leakage.

[0046] As a further solution of the present invention,

[0047] The above-mentioned continues to utilize the gravity change value formed by the pressurization and air leakage state of the closed variable pressure monitoring chamber corresponding to the mobile oxygen inhalation device to jointly verify the monitoring performance of the monitoring and calibration function architecture. Specifically, it includes:

[0048] Continue to use the variable pressure monitoring sensor in the monitoring and calibration function architecture to monitor and obtain the real-time internal pressure P of the closed variable pressure monitoring chamber corresponding to the current third node t3 of the time axis m3 , then the real-time internal pressure change amplitude P e from the initial placement of the mobile oxygen inhalation device to the third node t3 of the time axis is calculated as follows:

[0049] P e =P m3 -P n (2)

[0050] Wherein, P n is the initial internal pressure formed in the closed variable pressure monitoring cavity after the mobile oxygen inhalation device is placed;

[0051] During the calculation from time axis node t2 to t3, the amplitude of the internal pressure increase P corresponding to the pressure boost is a , and the calculation formula is as follows:

[0052] P a = R a ×(t3 - t2) (3)

[0053] Thus, by performing a difference calculation, the total amplitude of the internal pressure increase P corresponding to air leakage from the initial placement of the mobile oxygen inhalation device to the third time axis node t3 is obtained, and the calculation formula is as follows: f , and the calculation formula is as follows:

[0054] P f = P e - P a (4)

[0055] Continuing to introduce the ideal gas state equation PV = NRT to calculate the total amplitude of the internal pressure increase P corresponding to air leakage inside the closed variable pressure monitoring cavity m, and the corresponding oxygen increment N. The calculation process is as follows: f The corresponding oxygen increment N is calculated as follows:

[0056] P f V = NRT (5)

[0057] N = P f V / RT (6)

[0058] Wherein, V is the preset standard space volume formed inside the closed variable pressure monitoring cavity after the mobile oxygen inhalation device is placed, N is the amount of substance of the leaked oxygen in moles, R is the ideal gas constant, and T is the preset constant temperature environment temperature of the gas inside the closed variable pressure monitoring cavity;

[0059] Further introducing the oxygen mass conversion equation, the mass M of the leaked oxygen is calculated, and the calculation formula is as follows:

[0060] M = N × M o (7)

[0061] Wherein, M is the mass of the leaked oxygen, N is the amount of substance of the leaked oxygen in moles, and M o is the molar mass of oxygen, with a value of 32 g / mol;

[0062] Through the cooperation of the vacuum monitoring sensor and the vacuum suction valve body, the internal pressure suction and monitoring process are carried out synchronously to make the inside of the closed vacuum comparison cavity form a vacuum state P0, thereby more accurately calculating the pressure difference between the upper and lower ends of the mobile oxygen inhalation device after the air leakage and pressure boost processes;

[0063] Continuously obtain the total gravity G3 of the flexible bottom bearing seat of the third node t3 of the current time axis and the leakage and pressure of the mobile oxygen supply device through several groups of sensing weighing platforms in real time. The calculation formula is as follows:

[0064] G3 = G4 + G0 + F1 (8)

[0065] Wherein, G4 is the current actual gravity of the mobile oxygen supply device after leakage, and F1 is the internal pressure acting force on the upper surface of the mobile oxygen supply device and the flexible bottom bearing seat corresponding to the time axis node t3;

[0066] The upper surface area of the preset mobile oxygen supply device and the flexible bottom bearing seat is S. Calculate the internal pressure acting force F1 on the upper surface of the mobile oxygen supply device and the flexible bottom bearing seat corresponding to the time axis node t3. Specifically:

[0067] F1 = P m3 × S (9)

[0068] Calculate the current actual gravity G4 of the mobile oxygen supply device after leakage. The calculation formula is as follows:

[0069] G4 = G3 - G0 - F1 (10)

[0070] G4 = G3 - G0 - P m3 × S (11)

[0071] Further introduce the gravity equation according to the leaked oxygen mass M to calculate the leakage loss gravity G5 of the mobile oxygen supply device corresponding to the time axis node t3. The calculation formula is as follows:

[0072] G5 = Mg (12)

[0073] Compare whether the obtained value of G4 + G5 is equal to the gravity value G2 of the initially placed mobile oxygen supply device within a specific error range. Since the gravity value G2 is measured separately by the sensing weighing platform, while the gravity values G4 and G5 are measured in cooperation by the sensing weighing platform, the vacuum monitoring sensor and the variable pressure monitoring sensor. Therefore, if the difference between the comparison values exceeds the specific error range, it proves that the monitoring performance of the sensing weighing platform and / or the vacuum monitoring sensor and / or the variable pressure monitoring sensor has excessive attenuation.

[0074] An oxygen supply monitoring system according to the shared self-service liquid oxygen oxygen supply monitoring method described above, comprising:

[0075] A monitoring and calibration function architecture construction module for constructing a leakage state monitoring, liquid level monitoring and monitoring performance calibration function architecture for the mobile oxygen supply device;

[0076] The closed cavity establishment module is used to form a closed vacuum comparison cavity and a closed variable pressure monitoring cavity respectively based on the mobile oxygen inhalation devices placed corresponding to the monitoring and calibration functional architecture;

[0077] The liquid level monitoring module is used to calculate the actual weighing data of the mobile oxygen inhalation device, and further convert it based on the actual weighing data of the mobile oxygen inhalation device to obtain its internal liquid level state, so as to complete the liquid level monitoring process;

[0078] The time-axis internal pressure monitoring module is used to obtain the real-time internal pressure of the closed vacuum comparison cavity as the initial internal pressure of the architecture through the monitoring and calibration functional architecture, and obtain the real-time internal pressures of the closed variable pressure monitoring cavity corresponding to different time-axis nodes;

[0079] The internal pressure comparison module is used to compare the real-time internal pressures of the closed variable pressure monitoring cavity corresponding to different time-axis nodes, and judge the air leakage state of the mobile oxygen inhalation device according to the internal pressure comparison result.

[0102] like Figures 1 to 5 As shown, the embodiment of the present invention provides a shared self-service liquid oxygen supply monitoring method, which is used to effectively monitor the changes in the built-in liquid oxygen level of shared oxygen breathing equipment, so as to assist in completing the established usage billing function, and at the same time, it can further monitor the leakage status of the oxygen breathing equipment in real time to effectively ensure the status availability of the oxygen breathing equipment, and can significantly reduce the continuous leakage through the boost setting, thereby improving the overall safety. In addition, it can also timely compare and verify the attenuation degree of the monitoring performance of the architecture, further improving the accuracy of monitoring the equipment liquid level and usage status. Specifically including the following steps:

[0103] S1: Please refer to Figure 2 and Figure 3 , build a functional architecture for leakage status monitoring, liquid level monitoring and monitoring performance calibration for mobile oxygen breathing equipment a;

[0104] The specific process is:

[0105] A monitoring bin structure 1 is provided, and a taking-in and putting-out channel 11 connected to the inner cavity thereof and a pressing cover 12 which is detachably and closedly assembled with the taking-in and putting-out channel 11 are provided on the top of the monitoring bin structure 1, and a lifting and driving structure 2 which is transmission-assembled and connected with the pressing cover 12 is provided on the back side of the monitoring bin structure 1, so as to open or press the pressing cover 12 by outputting kinetic energy through the lifting and driving structure 2;

[0106] Continue to fixedly arrange several groups of directional guide plates 13 corresponding to the inner cavity of the monitoring chamber structure 1, and fixedly arrange several groups of sensing weighing platforms 3 at the bottom of the inner cavity of the monitoring chamber structure 1. And a ring-shaped flexible bottom bearing seat 31 is jointly positioned at the top of the outer edge corresponding to several groups of the sensing weighing platforms 3. The flexible bottom bearing seat 31 is correspondingly arranged between the guiding positions formed by several groups of the directional guide plates 13, so as to accurately position and assist in the closed support of the bottom end of the mobile oxygen inhalation device a through the flexible bottom bearing seat 31. At this time, a closed variable pressure monitoring chamber m is formed corresponding to the outer side of the mobile oxygen inhalation device a and the flexible bottom bearing seat 31 in the inner cavity of the monitoring chamber structure 1, and a closed vacuum comparison chamber n is formed in the inner side of the mobile oxygen inhalation device a and the flexible bottom bearing seat 31, so as to assist in completing the functions of air leakage state monitoring, liquid level monitoring and monitoring performance calibration through the closed variable pressure monitoring chamber m. At the same time, the closed vacuum comparison chamber n is used to assist in maintaining the constant vacuum at the bottom of the mobile oxygen inhalation device a, thereby avoiding the defect that the pressure difference between the upper and lower end faces of the mobile oxygen inhalation device a is too large / unstable during the subsequent inner cavity pressurization process, resulting in inaccurate weighing and corresponding liquid level calculation.

[0107] Further, a vacuum monitoring sensor 4 and a vacuum suction valve body 5 are respectively arranged corresponding to the closed vacuum comparison chamber n, so as to monitor and maintain the closed vacuum comparison chamber n in a constant vacuum state in real time.

[0108] At the same time, a pressurized blowing valve body 6, a variable pressure monitoring sensor 7 and a recovery suction valve body 8 are arranged corresponding to the closed variable pressure monitoring chamber m to monitor and complete the constant pressure and variable pressure states of the closed variable pressure monitoring chamber m in real time.

[0109] The electronic control module is electrically connected to the lifting drive structure 2, the vacuum monitoring sensor 4, the vacuum suction valve body 5, the pressurized blowing valve body 6, the variable pressure monitoring sensor 7 and the recovery suction valve body 8 through circuits respectively.

[0110] S2: Please refer to Figures 2 to 4 , and the closed vacuum comparison chamber n and the closed variable pressure monitoring chamber m are respectively formed for the mobile oxygen inhalation device a placed corresponding to the monitoring and calibration function architecture.

[0111] The specific process is as follows:

[0112] Control and start the lifting drive structure 2 to output kinetic energy to lift the cover body 12 to open the access channel 11.

[0113] Place the mobile oxygen inhalation device a into the inner cavity of the monitoring chamber structure 1 through the access channel 11, and shift it along the directional guide plate 13 until it is in closed contact with the flexible bottom bearing seat 31 on the top of several groups of sensing weighing platforms 3, so that the mobile oxygen inhalation device a forms a closed vacuum comparison chamber n corresponding to the inner side of the flexible bottom bearing seat 31.

[0114] At this time, the total gravity G1 of the initially placed mobile oxygen inhalation device a and the flexible bottom bearing seat 31 is obtained in real time through several groups of sensing and weighing platforms 3, where the preset gravity of the flexible bottom bearing seat 31 is G0;

[0115] Continue to control the driving press-fitting cover body 12 to be hermetically closed on the access channel 11, so that the inner cavity of the monitoring chamber structure 1 forms a closed variable-pressure monitoring chamber m corresponding to the outer side of the mobile oxygen inhalation device a and the flexible bottom bearing seat 31;

[0116] S3: Calculate the actual weighing data of the mobile oxygen inhalation device a, and further convert it based on the actual weighing data of the mobile oxygen inhalation device a to obtain its internal liquid level state, so as to complete the liquid level monitoring process;

[0117] The specific process is as follows:

[0118] According to the obtained total gravity G1 of the initially placed mobile oxygen inhalation device a and the flexible bottom bearing seat 31, calculate the current actual gravity G2 of the initially placed mobile oxygen inhalation device a. The specific calculation formula is:

[0119] G2 = G1 - G0 (1)

[0120] In the formula, G0 is the preset gravity value of the flexible bottom bearing seat 31;

[0121] After that, based on the current actual gravity G2 of the mobile oxygen inhalation device a, further convert it through the conversion coefficient to obtain the liquid level value of the mobile oxygen inhalation device a at the initial placement, so as to complete the liquid level monitoring process;

[0122] S4: Obtain the real-time internal pressure of the closed vacuum comparison chamber n as the initial internal pressure of the architecture through the monitoring and calibration function architecture, and obtain the real-time internal pressure of the closed variable-pressure monitoring chamber m corresponding to different time axis nodes;

[0123] The specific process is as follows:

[0124] Obtain the real-time internal pressure P of the closed variable-pressure monitoring chamber m corresponding to the first node t1 of the current time axis through the variable-pressure monitoring sensor 7 in the monitoring and calibration function architecture m1 , and obtain the real-time internal pressure P of the closed vacuum comparison chamber n corresponding to the first node t1 of the current time axis through the vacuum monitoring sensor 4 n . At this time, since the closed vacuum comparison chamber n is closed immediately after the initial placement of the mobile oxygen inhalation device a, the internal pressure P of the closed vacuum comparison chamber n n is used as the initial internal pressure P of the inner cavity of the monitoring chamber structure 1 after the placement process n ;

[0125] Continue to obtain the real-time internal pressure P of the closed variable-pressure monitoring chamber m corresponding to the second node t2 of the current time axis through the variable-pressure monitoring sensor 7 in the monitoring and calibration function architecture m2 ;

[0126] S5: Compare the real-time internal pressures of the obtained sealed variable-pressure monitoring cavity m corresponding to different time-axis nodes, and determine the air leakage state of the mobile oxygen inhalation device a according to the results of the internal pressure comparison;

[0127] The specific process is as follows:

[0128] Compare the real-time internal pressure values of the obtained sealed variable-pressure monitoring cavity m corresponding to the first node t1 and the second node t2 of the current time axis, as follows:

[0129] If P m2 = P m1 = P n , it proves that the internal pressure of the sealed variable-pressure monitoring cavity m from the first node t1 to the second node t2 of the current time axis has not increased, and at this time, the mobile oxygen inhalation device a is not in a state of air leakage;

[0130] If P m2 > P m1 , it proves that the internal pressure of the sealed variable-pressure monitoring cavity m from the first node t1 to the second node t2 of the current time axis has increased, and at this time, the mobile oxygen inhalation device a is in a state of air leakage;

[0131] S6: When the mobile oxygen inhalation device a is in a state of air leakage, control the monitoring and calibration function architecture to pressurize the sealed variable-pressure monitoring cavity m until the pressure at the leakage point is balanced and the air leakage stops;

[0132] The specific process is as follows:

[0133] Through the cooperation of the pressurizing and blowing valve body 6 and the variable-pressure monitoring sensor 7 in the monitoring and calibration function architecture, input oxygen into the sealed variable-pressure monitoring cavity m from the second node t2 of the time axis to pressurize the inside of the sealed variable-pressure monitoring cavity m. The variable-pressure monitoring sensor 7 monitors and records the real-time internal pressure increase speed value of the current sealed variable-pressure monitoring cavity m as the total internal pressure increase speed R corresponding to pressurization and air leakage m ;

[0134] During the gradual pressurization process inside the sealed variable-pressure monitoring cavity m, the air leakage amount at the leakage point of the mobile oxygen inhalation device a gradually decreases under the action of the external pressure. At this time, the internal pressure increase speed corresponding to the air leakage decreases synchronously. When the internal pressure increase speed R a preset remains unchanged, the total internal pressure increase speed R m then decreases synchronously;

[0135] Continue to monitor and record the total internal pressure increase speed R m of the sealed variable-pressure monitoring cavity m. When reaching the third node t3 of the time axis, the total internal pressure increase speed R mWhen it no longer decreases gradually but maintains a constant value within the preset threshold range, the pressure boosting is immediately stopped. At this time, the internal pressure increase rate corresponding to the air leakage is 0, and the finally monitored total internal pressure increase rate R m is the preset internal pressure increase rate R corresponding to the pressure boosting a , thus completing the pressure balance regulation for the leakage point position of the mobile oxygen inhalation device a, preventing waste and potential safety hazards caused by continuous oxygen leakage;

[0136] S7: Continue to cooperate with the gravity change value formed by the pressure boosting and air leakage states of the closed variable-pressure monitoring chamber m for the mobile oxygen inhalation device a to verify and calibrate the monitoring performance of the monitoring and calibration functional architecture;

[0137] The specific process is as follows:

[0138] Continue to obtain the real-time internal pressure P of the closed variable-pressure monitoring chamber m corresponding to the third node t3 of the current time axis in real time through the variable-pressure monitoring sensor 7 in the monitoring and calibration functional architecture m3 , then the real-time internal pressure change amplitude P e from the initial placement of the mobile oxygen inhalation device a to the third node t3 of the time axis is calculated as follows:

[0139] P e =P m3 -P n (2)

[0140] In the formula, P n is the initial internal pressure formed by the closed variable-pressure monitoring chamber m after the placement of the mobile oxygen inhalation device a;

[0141] Calculate the internal pressure increase amplitude P a corresponding to the pressure boosting within the time axis nodes t2 to t3, and the calculation formula is as follows:

[0142] P a =R a ×(t3 - t2) (3)

[0143] Thus, the total internal pressure increase amplitude P f corresponding to the air leakage from the initial placement of the mobile oxygen inhalation device a to the third node t3 of the time axis is obtained by subtraction, and the calculation formula is as follows:

[0144] P f =P e -P a (4)

[0145] Continue to introduce the ideal gas state equation PV = NRT to calculate the corresponding oxygen increment N for the total internal pressure increase amplitude P f corresponding to the air leakage inside the closed variable-pressure monitoring chamber m, and the calculation process is as follows:

[0146] Pf V = NRT (5)

[0147] N = P f V / RT (6)

[0148] Wherein, V is the preset standard space volume formed inside the closed variable pressure monitoring chamber m after the placement of the mobile oxygen inhalation device a, N is the amount of substance of the leaked oxygen in moles, R is the ideal gas constant, and T is the preset gas constant temperature environment temperature inside the closed variable pressure monitoring chamber m;

[0149] Furthermore, the oxygen mass conversion equation is introduced to calculate the mass M of the leaked oxygen, and the calculation formula is as follows:

[0150] M = N × M o (7)

[0151] Wherein, M is the mass of the leaked oxygen, N is the amount of substance of the leaked oxygen in moles, and M o is the molar mass of oxygen, with a value of 32 g / mol;

[0152] Please refer to Figure 5 , through the cooperation of the vacuum monitoring sensor 4 and the vacuum suction valve body 5, the internal pressure suction and monitoring process are carried out synchronously to form a vacuum state P0 inside the closed vacuum comparison chamber n, so as to more accurately calculate the pressure difference between the upper and lower end faces of the mobile oxygen inhalation device a after the air leakage and pressurization processes;

[0153] Continue to obtain the total gravity G3 of the flexible bottom bearing 31 and the mobile oxygen inhalation device a after air leakage and pressure through several groups of sensing weighing platforms 3 in real time at the third node t3 of the current time axis, and the calculation expression is as follows:

[0154] G3 = G4 + G0 + F1 (8)

[0155] Wherein, G4 is the current actual gravity of the mobile oxygen inhalation device a after air leakage, and F1 is the internal pressure acting force on the upper surface of the mobile oxygen inhalation device a and the flexible bottom bearing 31 corresponding to the time axis node t3;

[0156] The upper surface area of the preset mobile oxygen inhalation device a and the flexible bottom bearing 31 is S, and the internal pressure acting force F1 on the upper surface of the mobile oxygen inhalation device a and the flexible bottom bearing 31 corresponding to the time axis node t3 is calculated as follows:

[0157] F1 = P m3 × S (9)

[0158] Calculate the current actual gravity G4 of the mobile oxygen inhalation device a after air leakage, and the calculation formula is as follows:

[0159] G4 = G3 - G0 - F1 (10)

[0160] G4 = G3 - G0 - P m3 ×S(11)

[0161] Further, according to the mass M of the leaked oxygen, a gravity equation is introduced to calculate the gravity loss G5 of the mobile oxygen inhalation device a corresponding to the time axis node t3. The calculation formula is as follows:

[0162] G5 = Mg(12)

[0163] Compare whether the obtained value of G4 + G5 is equal to the gravity value G2 of the initially placed mobile oxygen inhalation device a within a specific error range. Since the gravity value G2 is measured separately by the sensing weighing platform 3, while the gravity values G4 and G5 are measured by the cooperation of the sensing weighing platform 3, the vacuum monitoring sensor 4 and the variable pressure monitoring sensor 7. Therefore, if the difference between the comparison values exceeds the specific error range, it proves that the monitoring performance of the sensing weighing platform 3 and / or the vacuum monitoring sensor 4 and / or the variable pressure monitoring sensor 7 has excessive attenuation.
