[0002] As a medical device that promotes human tissue repair by precisely regulating the oxygen concentration and pressure in the chamber, the micro-hyperbaric oxygen chamber has been widely used in clinical treatment (such as carbon monoxide poisoning and wound healing), rehabilitation health care, and sports medicine.
[0003] Its core air conditioning system covers key links such as compressor air supply, filter impurity filtration, pipeline pressure control and sealing. The performance degradation of any component may cause systemic risks.
[0004] However, failures in the air conditioning system (such as compressors, filters, and pipe seals) can lead to treatment interruptions, safety risks, or decreased efficacy. Existing monitoring technologies, which are mostly based on single parameters (such as pressure and temperature), lack the ability to comprehensively assess complex failure modes (such as wear-corrosion coupling and coordinated failure of multiple components), making it difficult to achieve early warning and precise location of failures.
[0005] Therefore, a micro-hyperbaric oxygen chamber oxygen supply system and a micro-hyperbaric oxygen chamber monitoring system are needed to address the above-mentioned problems. Summary of the Invention

A pressure value greater than the pressure threshold is recorded as an abnormal pressure value, and the difference between each abnormal pressure value and the pressure threshold is calculated to obtain a pressure deviation value; Count the number of pressure deviation values and divide it by the number of all pressure values to get the degree of deviation; Arrange the pressure deviation values in descending order according to their numerical values, extract the four largest pressure deviation values, and use the pressure sensor positions corresponding to the four largest pressure deviation values as endpoints. Connect the four endpoints with straight lines to form a tetrahedron, and calculate the volume of the tetrahedron as the quantized value. The congestion coefficient is obtained by weighting the deviation value and the quantization value.

[0013] Preferably, the monitoring and evaluation coefficient is obtained by comprehensively processing the compressor abnormality coefficient, the blockage coefficient and the leakage possibility coefficient, which specifically includes: After normalizing the compressor abnormality coefficient, blockage coefficient and leakage possibility coefficient, the compressor abnormality coefficient and blockage coefficient are used as the two right-angled sides of a right triangle respectively, and the remaining side is connected to form a complete right triangle. The blockage coefficient is used as the height of the right triangle to construct a triangular pyramid model, and the volume of the triangular pyramid model is calculated and recorded as the monitoring evaluation coefficient.

The blockage coefficient is used as the height of the right triangle to construct a triangular pyramid model. The volume of the triangular pyramid model is calculated and recorded as the monitoring evaluation coefficient. Judgment module: obtains the corresponding air conditioning fault status level based on the monitoring evaluation coefficient and performs corresponding processing; Three groups of threshold value ranges are preset. Each threshold value range corresponds to an air conditioning fault status level. The monitoring evaluation coefficient is matched with the three threshold value ranges to obtain the air conditioning fault status level corresponding to the monitoring evaluation coefficient, including slight abnormality, moderate fault, and severe fault. When the fault status level is slightly abnormal: strengthen monitoring, record abnormal data trends, arrange regular maintenance, and prevent fault escalation; When the fault status is moderate: immediately initiate troubleshooting to locate the source of the abnormality (such as pipeline leakage, decreased compressor efficiency), and prioritize repairing or replacing damaged components to prevent the fault from spreading. When the fault status level is serious fault: emergency shutdown, power off, prohibition of further operation, professional team comprehensive inspection, replacement of seriously damaged parts, re-debug the system.
