[0033] Figure 1 The figure is a schematic flow chart of the method steps of the present invention. DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Reference Figure 1 As shown, the first aspect of the present invention provides a control method for a noise reduction ventilation system, comprising: S1. Detecting the environment of a medical air compressor: acquiring environmental data of the area to which the medical air compressor belongs, analyzing to obtain an air compressor environmental impact index, and comparing the data with the air compressor environmental impact index boundary value preset in a ventilation control database to obtain an environmental impact comparison result, and determining whether it is necessary to issue an early warning prompt for the environment of the area to which the medical air compressor belongs based on the environmental impact comparison result.

[0036] In this embodiment, the noise reduction ventilation system is a system specially designed to address the noise and heat generated by medical air compressors during operation. The noise reduction ventilation system significantly reduces the noise level of medical air compressors by adopting effective noise reduction measures, providing a more comfortable medical environment for medical staff and patients. The noise reduction ventilation system can effectively discharge the heat generated by the compressor through reasonable ventilation design, keeping the compressor operating within a normal operating temperature range.

[0037] S2. Performance testing of medical air compressors: obtain the performance data of the medical air compressor, and conduct a comprehensive analysis with the air compressor environmental impact index to obtain the medical air compressor operation performance stability index, and compare it with the medical air compressor operation performance stability index limit value preset in the ventilation control database to obtain the operation stability comparison result. Based on the operation stability comparison result, determine whether it is necessary to issue an early warning prompt for the operation performance of the medical air compressor.

[0038] S3. Output air quality detection: The real-time noise intensity and air quality data of the medical air compressor during the compression cycle are comprehensively analyzed to obtain the medical air compressor function index, and compared with the medical air compressor function index boundary value preset in the ventilation control database to obtain the function comparison result. Finally, based on the function comparison result, it is determined whether it is necessary to issue an early warning prompt for the function of the medical air compressor.

[0039] Specifically, the environmental data of the area to which the medical air compressor belongs includes the real-time ambient temperature, real-time ambient air pressure, real-time electromagnetic interference intensity, real-time particulate matter concentration and real-time harmful gas concentration of the medical air compressor during the detection period.

[0040] It should be explained that the real-time ambient temperature of the above-mentioned medical air compressor during the detection period is measured by a temperature sensor installed near the medical air compressor, the real-time ambient air pressure is measured by an air pressure sensor, the real-time electromagnetic interference intensity is measured by an electromagnetic interference detection device, the real-time particulate matter concentration can be measured by a particle counter device, and the real-time harmful gas concentration is measured by a harmful gas detector. These detectors can detect the concentration of specific harmful gases in the air, such as carbon dioxide, carbon monoxide, oxygen, etc.; in this embodiment, the detection period refers to the time interval for regular detection of various environmental parameters. This period is usually randomly determined based on the frequency of use of the medical air compressor, its importance and the fluctuation of environmental parameters.

[0041] In this embodiment, there is a mutual influence relationship between the above-mentioned real-time ambient temperature, real-time ambient air pressure, real-time electromagnetic interference intensity, real-time particulate matter concentration and real-time harmful gas concentration. Changes in ambient temperature will affect the ambient air pressure. Generally speaking, as the temperature rises, the thermal motion between air molecules intensifies, which may cause a slight decrease in air pressure. In a high temperature environment, particulate matter may be more easily suspended in the air, increasing its concentration. Under lower air pressure, particulate matter may be more easily suspended in the air, increasing its concentration. Under high temperature conditions, the solubility of certain harmful gases will decrease, which will lead to an increase in the concentration of harmful gases.

[0042] The real-time particle concentration of the medical air compressor during the detection period is ratio-processed with the allowable particle concentration preset in the ventilation control database to obtain the real-time particle concentration ratio of the medical air compressor during the detection period.

[0043] The real-time harmful gas concentration of the medical air compressor during the detection period is ratio-processed with the allowable concentration of harmful gases preset in the ventilation control database to obtain the real-time harmful gas concentration ratio of the medical air compressor during the detection period.

[0044] Specifically, the environmental impact index of the air compressor is analyzed in the following steps: The real-time ambient temperature of the medical air compressor during the detection period is processed with the ambient reference temperature preset in the ventilation control database to obtain the real-time ambient temperature difference of the medical air compressor during the detection period.

[0045] The real-time ambient air pressure of the medical air compressor during the detection period is processed with the ambient reference air pressure preset in the ventilation control database to obtain the real-time ambient air pressure difference of the medical air compressor during the detection period.

[0046] The real-time electromagnetic interference intensity, real-time particle concentration ratio, real-time ambient temperature difference and real-time ambient pressure difference of the medical air compressor during the detection period are comprehensively analyzed to obtain the environmental impact index of the air compressor. The specific analysis method is as follows:

[0047] In the formula, is the environmental impact index of the air compressor, e is a natural constant, is the starting time point of the detection cycle, is the end time of the detection cycle, t is any time point in the detection cycle, , is the real-time electromagnetic interference intensity of the medical air compressor at time point t within the detection period, The electromagnetic permissible interference intensity preset for the ventilation control database, is the real-time particle concentration ratio of the medical air compressor at time point t within the detection period, The influence factor corresponding to the unit value of the particle concentration preset in the ventilation control database, is the real-time concentration ratio of harmful gases in the medical air compressor at time point t within the detection period, The influence factor corresponding to the unit value of harmful gas concentration preset in the ventilation control database, is the real-time ambient temperature difference of the medical air compressor at time point t within the detection cycle, The ambient allowable temperature difference value preset for the ventilation control database, is the real-time ambient air pressure difference of the medical air compressor at time point t within the detection cycle, The allowable difference in air pressure preset for the ventilation control database.

[0048] It should be explained that the above-mentioned arbitrary time point in the detection cycle refers to any time point when the medical air compressor is detected within the specific detection cycle set by the medical air compressor; the real-time electromagnetic interference intensity refers to the intensity of the interference signal existing in the electromagnetic environment at the current moment; the electromagnetic allowable interference intensity preset in the ventilation control database refers to the maximum electromagnetic interference intensity allowed in a specific ventilation control system to ensure the normal operation and safety of the system; the real-time particle concentration ratio refers to the ratio between the real-time particle concentration of the medical air compressor during the detection cycle and the allowable particle concentration preset in the ventilation control database; the real-time harmful gas concentration ratio refers to the ratio between the real-time harmful gas concentration of the medical air compressor during the detection cycle and the allowable harmful gas concentration preset in the ventilation control database; the real-time ambient temperature difference refers to the difference between the real-time ambient temperature of the medical air compressor during the detection cycle and the ambient reference temperature preset in the ventilation control database; the allowable ambient temperature difference preset in the ventilation control database refers to the maximum ambient temperature difference allowed in a specific ventilation control system to ensure the comfort and energy saving of the system; the real-time ambient air pressure difference refers to the real-time ambient air pressure difference of the medical air compressor during the detection cycle. The difference between the pressure and the ambient reference pressure preset in the ventilation control database; the allowable pressure difference preset in the wind control database refers to the maximum pressure difference allowed in a specific ventilation control system in order to ensure the normal operation and safety of the system; the influence factor corresponding to the unit value of the particle concentration ratio preset in the ventilation control database indicates the degree of influence of the unit value of the particle concentration ratio on the environmental impact index of the air compressor, and the corresponding relationship between the unit value of the particle concentration ratio and its corresponding influence factor is stored in the ventilation control database. For example, the unit value of the particle concentration ratio is input into the ventilation control database, and the ventilation control database can match the influence factor corresponding to the unit value of the particle concentration ratio. In this embodiment, the value range is (0, 1); the influence factor corresponding to the unit value of the harmful gas concentration ratio preset in the ventilation control database indicates the degree of influence of the unit value of the harmful gas concentration ratio on the environmental impact index of the air compressor. The corresponding relationship between the unit value of the harmful gas concentration ratio and its corresponding influence factor is stored in the ventilation control database. For example, the unit value of the harmful gas concentration ratio is input into the ventilation control database, and the ventilation control database can match the influence factor corresponding to the unit value of the harmful gas concentration ratio. In this embodiment, the value range is (0, 1).

[0049] In this embodiment, when the electromagnetic interference intensity is relatively strong, even greater than the preset electromagnetic interference intensity, the electronic components, sensors or control systems inside the air compressor will fail, affecting the normal operation of the equipment. At the same time, the electromagnetic interference will also cause errors in the data collected by the sensor, thereby affecting the accuracy of the environmental impact index; a large particle concentration ratio will increase the burden on the air filter and shorten its service life, and may also cause wear on the mechanical parts inside the compressor, reducing the overall performance of the equipment; when the concentration of harmful gases is relatively large, it will not only pose a threat to human health, but may also corrode the metal parts inside the compressor, affecting its long-term stability; when the ambient temperature difference is relatively large, even greater than the preset ambient allowable temperature difference, the internal temperature of the compressor will be too high, affecting the performance of the lubricating oil and the heat dissipation effect of the compressor, thereby affecting the operating efficiency and life of the equipment; when the ambient pressure difference is relatively large, even greater than the preset pressure allowable difference, it will affect the suction and exhaust process of the compressor, resulting in a decrease in compression efficiency; therefore, by analyzing the various parameters in the environmental impact index of the air compressor in detail, potential problems can be discovered in a timely manner and measures can be taken to adjust or maintain them, thereby ensuring that the medical air compressor operates in the best environment, ensuring the air quality of the medical environment and the safe and stable operation of the equipment.

[0050] Furthermore, the environmental impact comparison result is used to determine whether it is necessary to issue an early warning for the environment of the area where the medical air compressor is located. The specific determination process is as follows: If the air compressor environmental impact index is greater than the air compressor environmental impact index limit value preset in the ventilation control database, the environmental impact comparison result is recorded as the environmental first impact comparison result.

[0051] If the air compressor environmental impact index is less than or equal to the air compressor environmental impact index limit value preset in the ventilation control database, the environmental impact comparison result is recorded as the environmental second impact comparison result.

[0052] If the environmental impact comparison result is the environmental first impact comparison result, it is necessary to issue an early warning reminder for the environment of the area where the medical air compressor is located.

[0053] In this embodiment, the air compressor environmental impact index is compared with the air compressor environmental impact index limit value preset in the ventilation control database. When the air compressor environmental impact index is less than or equal to the air compressor environmental impact index limit value preset in the ventilation control database, it means that the current environmental conditions are within a safe or comfortable range and will not have a significant impact on equipment performance or environmental quality; when the air compressor environmental impact index is greater than the air compressor environmental impact index limit value preset in the ventilation control database, it means that the current environmental conditions have exceeded the safety or comfort threshold and may have an adverse effect on equipment performance or environmental quality. The environmental impact comparison result in this case is recorded as the environmental first impact comparison result. At the same time, it is necessary to give an early warning prompt for the environment of the area where the medical air compressor is located. The specific early warning prompt can be displayed on the system's monitoring interface with specific text prompts, such as "Please note that the environmental impact is large, please start the environmental ventilation system."

[0054] Specifically, the performance data of the medical air compressor includes real-time power consumption, real-time noise intensity, real-time input pressure, real-time air output flow, real-time air intake flow and real-time exhaust pressure of the medical air compressor during a detection period.

[0055] It should be explained that the above-mentioned real-time power consumption is obtained by connecting an electric energy metering device (such as an electric energy meter or a power meter) to obtain the real-time power consumption of the medical air compressor, the real-time noise intensity is obtained by measuring using a noise measuring instrument, the real-time input pressure is obtained by measuring using a pressure gauge connected to the air inlet pipe of the medical air compressor, the real-time exhaust pressure is obtained by measuring using a pressure gauge connected to the exhaust pipe of the medical air compressor, the real-time air output flow is measured using a flow meter connected to the air outlet pipe of the medical air compressor, and the real-time air intake flow is measured using a flow meter connected to the air intake pipe of the medical air compressor. Similarly, the real-time air intake flow is measured using a flow meter connected to the intake pipe of the medical air compressor; in this embodiment, the detection cycle refers to the time interval for regular inspection and performance evaluation of the medical air compressor. This cycle is usually randomly determined based on the frequency of use of the compressor and the working environment conditions. The detection cycle of these performance parameters is the same as the environmental detection cycle of the area to which the above-mentioned medical air compressor belongs, because these parameters take into account the influence of environmental conditions and need to be monitored regularly to ensure the normal operation and stable performance of the compressor.

[0056] In this embodiment, there is a certain correlation between the real-time power consumption, real-time noise intensity, real-time input pressure, real-time air output flow, real-time air intake flow and real-time exhaust pressure of the above-mentioned medical air compressor during the detection period. These parameters jointly reflect the operating status and working efficiency of the compressor. As the air output flow increases, the power consumption of the medical air compressor will also increase accordingly. The increase in exhaust pressure may also lead to an increase in power consumption. As the power consumption increases, the mechanical movement and vibration inside the compressor will intensify, thereby increasing the noise intensity. The increase in exhaust pressure leads to the acceleration of gas flow and the intensification of collision inside the compressor, thereby generating greater noise. When the input pressure is low, the intake flow may be limited because the compressor needs to overcome a greater negative pressure to inhale gas. There is a certain relationship between the input pressure and the exhaust pressure. In some cases, an increase in input pressure will lead to an increase in exhaust pressure. The increase in exhaust pressure will affect the air output flow. When the exhaust pressure rises to a certain level, the increase in output flow will be limited because the compressor needs to overcome greater resistance to discharge gas.

[0057] The real-time air intake flow rate and the real-time air output flow rate of the medical air compressor during the detection period are subjected to difference processing to obtain the real-time air loss amount of the medical air compressor during the detection period.

[0058] Specifically, the operation performance stability index of the medical air compressor is analyzed in the following steps: The real-time input pressure and the real-time exhaust pressure of the medical air compressor during the detection period are subjected to difference processing to obtain the real-time pressure difference of the medical air compressor during the detection period.

[0059] The air compressor environmental impact index, the real-time power consumption, real-time noise intensity, real-time air loss and real-time pressure difference of the medical air compressor during the detection period are comprehensively analyzed to obtain the medical air compressor operation performance stability index. The specific analysis method is as follows: ; In the formula, is the operating performance stability index of the medical air compressor, e is a natural constant, It is the environmental impact index of air compressor. The operation impact index corresponding to the unit value of the air compressor environmental impact index preset in the ventilation control database, is the starting time point of the detection cycle, is the end time of the detection cycle, t is any time point in the detection cycle, , is the real-time power consumption of the medical air compressor at time point t within the detection cycle, The reference power consumption preset for the ventilation control database, is the real-time noise intensity of the medical air compressor at time point t within the detection period, The noise tolerance level preset for the ventilation control database, is the real-time air loss of the medical air compressor at time point t within the detection cycle, The air loss allowance preset for the ventilation control database, is the real-time pressure difference of the medical air compressor at time point t within the detection cycle, Pressure reference differential preset for ventilation control database.

[0060] It should be explained that the above-mentioned air compressor environmental impact index refers to a comprehensive index used to evaluate the impact of the surrounding environment on the operation of the air compressor; real-time power consumption refers to the actual power consumed by the air compressor at a specific point in time; the reference power consumption preset in the ventilation control database refers to the power value required to maintain the normal operation of the air compressor; real-time noise intensity refers to the noise level generated by the operation of the air compressor at the current moment; the allowable noise intensity preset in the ventilation control database refers to the maximum noise intensity allowed by the air compressor in a specific ventilation control system; real-time air loss refers to the difference between the real-time air intake flow and the real-time air output flow of the medical air compressor during the detection period; the allowable air loss preset in the ventilation control database refers to the amount of air loss allowed during the operation of the air compressor in a specific ventilation control system in order to ensure the normal operation and energy saving of the system. air volume; the real-time pressure difference refers to the difference between the real-time input pressure and the real-time exhaust pressure of the medical air compressor within the detection period; the pressure reference difference preset in the ventilation control database refers to the reference difference between the inlet and outlet pressures of the air compressor in order to maintain environmental stability and meet the normal operation of the equipment in a specific ventilation control system; the operation impact index corresponding to the unit value of the air compressor environmental impact index preset in the ventilation control database represents the degree of influence of the unit value of the air compressor environmental impact index on the medical air compressor operation performance stability index. The ventilation control database stores the corresponding relationship between the unit value of the air compressor environmental impact index and its corresponding operation impact index. For example, the unit value of the air compressor environmental impact index is input into the ventilation control database, and the ventilation control database can match the operation impact index corresponding to the unit value of the air compressor environmental impact index. In this embodiment, the value range is (0, 1).

[0061] In this embodiment, when the air compressor environmental impact index is large, it means that the environmental conditions of the air compressor are relatively harsh, such as high temperature, dust, etc. These adverse environmental conditions will increase the operating burden of the air compressor, resulting in accelerated wear of components and performance degradation, thereby resulting in a decrease in the medical air compressor operating performance stability index; when the power consumption is large or small, that is, when the degree of deviation from the preset reference power consumption is large, it indicates that there may be problems with the operating efficiency of the air compressor. Excessive power may cause energy waste, and too little power may not meet medical needs. Both of these situations will reduce the medical air compressor operating performance stability index; a large noise intensity, even greater than the preset noise allowable intensity, will interfere with the medical environment. In addition, excessive noise may also intentionally It means that the air compressor has mechanical failure or unbalanced operation, which further reduces the medical air compressor operation performance stability index; when the air loss is large, even greater than the preset allowable air loss, the efficiency of the medical air compressor will be reduced, affecting the normal operation of medical equipment, resulting in a reduction in the medical air compressor operation performance stability index; a large pressure difference, even greater than the preset pressure reference difference, may mean that the output pressure of the air compressor is unstable or there is a leakage, which will cause the medical air compressor to be unable to meet medical needs and reduce its operation performance stability index; therefore, through a detailed analysis of each parameter in the medical air compressor operation performance stability index, potential problems can be discovered and solved in a timely manner to ensure the efficient and stable operation of the air compressor.

[0062] Furthermore, the specific determination process of determining whether it is necessary to issue an early warning prompt for the operation performance of the medical air compressor according to the operation stability comparison result is as follows: If the medical air compressor operating performance stability index is greater than or equal to the medical air compressor operating performance stability index limit value preset in the ventilation control database, the operating stability comparison result will be recorded as the first operating stability comparison result.

[0063] If the medical air compressor operating performance stability index is less than the medical air compressor operating performance stability index limit value preset in the ventilation control database, the operating stability comparison result will be recorded as the second operating stability comparison result.

[0064] If the operation stability comparison result is the second operation stability comparison result, it is necessary to give an early warning prompt for the operation performance of the medical air compressor.

[0065] In this embodiment, the medical air compressor operating performance stability index is compared with the medical air compressor operating performance stability index limit value preset in the ventilation control database. When the medical air compressor operating performance stability index is greater than or equal to the medical air compressor operating performance stability index limit value preset in the ventilation control database, it means that the medical air compressor is operating stably, and the operation stability comparison result is recorded as the first operation stability comparison result, and no special warning is required at this time; when the medical air compressor operating performance stability index is less than the medical air compressor operating performance stability index limit value preset in the ventilation control database, it means that the operation of the medical air compressor may be abnormal or unstable, and the operation stability comparison result is recorded as the first operation stability comparison result. The fixed comparison result is recorded as the second comparison result of stable operation. At this time, early warning prompts are needed. The specific early warning prompts can be provided by an audible and visual alarm installed near the medical air compressor. When the operating performance stability index is lower than the limit value, the alarm will send out audible and visual signals to remind on-site personnel to pay attention. After receiving the early warning prompt, relevant personnel should first check whether there are any faults or abnormalities in the medical air compressor itself, such as checking the pressure gauge, whether the electrical connection is loose or burned, whether the lubricating oil is sufficient, etc., check the real-time power consumption, exhaust pressure, exhaust temperature and other key parameters of the medical air compressor, and according to the inspection results, perform corresponding maintenance or replace parts of the medical air compressor to ensure its normal operation.

[0066] Specifically, the functional indicators of the medical air compressor are analyzed in the following steps: Get real-time noise intensity of medical air compressors during the compression cycle.

[0067] It needs to be explained that the real-time noise intensity of the above-mentioned medical air compressor during the compression cycle is obtained by measuring with a noise measuring instrument, where the compression cycle refers to a complete working process of the medical air compressor from starting to inhale to completing the exhaust and preparing to inhale again. During this process, the moving parts such as the piston or screw inside the compressor will reciprocate or rotate to achieve compression of the gas. The length of the compression cycle depends on many factors such as the design of the compressor, operating conditions and load conditions.

[0068] The air quality data specifically includes the real-time air pressure, real-time flow, real-time oil content, real-time particulate matter concentration and real-time humidity of the air during the compression cycle.

[0069] It should be explained that the above-mentioned real-time air pressure is measured by an air pressure sensor, the real-time flow rate is measured by a flow sensor, the real-time oil content is measured by an oil concentration sensor, the real-time particle concentration is measured by a particle counter device, and the real-time humidity is measured by a humidity sensor.

[0070] The performance data of the air compressor during the compression cycle is obtained and analyzed to obtain the air compression stability index.

[0071] In this embodiment, the performance data of the above-mentioned air compressor during the compression cycle is the same as the performance data of the above-mentioned medical air compressor. Therefore, the analysis process and method used to obtain the medical air compressor operating performance stability index obtained by analyzing the performance data of the medical air compressor can also analyze the performance data of the air compressor during the compression cycle to obtain the air compression stability index.

[0072] The air compression stability index, real-time air pressure during the compression cycle, real-time flow, real-time oil content, real-time particle concentration and real-time humidity are comprehensively analyzed to obtain the functional index of the medical air compressor.

[0073] It should be explained that the air compression stability index is a key indicator to measure the performance stability and reliability of medical air compressors. It reflects whether the compressor can maintain the stability of the pressure, flow and other parameters of the output gas during long-term operation. If the air compression is unstable, the air pressure will fluctuate, affecting the air pressure supply. If the compressed air is unstable, the flow may fluctuate, resulting in the medical air compressor being unable to obtain a stable flow supply. If the compressed air is unstable, the oil content will fluctuate, thereby increasing the risk of blockage or damage to the medical air compressor. If the compressed air is unstable, the particle concentration will fluctuate, thereby increasing the risk of failure of the medical air compressor. If the compressed air is unstable, the humidity will fluctuate, affecting the performance and accuracy of the medical air compressor. For example, too high humidity may cause the medical air compressor to rust or corrode, while too low humidity may cause the equipment to dry out and crack.

[0074] The specific analysis method of the medical air compressor function index is as follows: ; In the formula, is the function index of medical air compressor, e is the natural constant, is the starting time point of the compression cycle, is the end time of the compression cycle, v is any time point within the compression cycle, , It is the air compression stability index. The functional impact index corresponding to the unit value of the air compression stability index preset in the ventilation control database. is the real-time air pressure at time point v during the compression cycle, The preset air pressure limit values ​​for the ventilation control database, is the real-time operating temperature of the air at time point v during the compression cycle, The operating allowable temperature preset for the ventilation control database, is the real-time flow rate of air at time point v during the compression cycle, Reference flow rates preset for ventilation control database, is the real-time oil content of the air at time point v during the compression cycle, The permissible oil content preset for the ventilation control database, is the real-time particle concentration of air at time point v during the compression cycle, The permitted concentration of particulate matter preset for the ventilation control database, is the real-time humidity of the air at time point v during the compression cycle, The permissible humidity preset for the ventilation control database.

[0075] It should be explained that the above-mentioned real-time air pressure refers to the outlet air pressure value of the medical air compressor at the current moment; the air pressure limit value preset in the ventilation control database refers to the preset minimum value of the air compressor outlet air pressure in a specific ventilation control system in order to maintain environmental stability and meet the normal operation of the equipment; the real-time operating temperature refers to the operating temperature of the medical air compressor at the current moment; the operating allowable temperature preset in the ventilation control database refers to the preset maximum operating temperature value in a specific ventilation control system in order to maintain the normal operation of the air compressor and prevent overheating; the real-time flow rate refers to the output flow rate at the current moment; the reference flow rate preset in the ventilation control database refers to the reference value of the air compressor output flow rate preset in a specific ventilation control system in order to maintain environmental stability and meet the normal operation of the equipment; the real-time oil content refers to the concentration of oil droplets contained in the compressed air output by the medical air compressor; the allowable oil content refers to the maximum oil concentration value allowed to ensure that medical equipment obtains high-quality compressed air supply; the real-time particulate matter Concentration refers to the concentration of particulate matter (such as dust, particles, etc.) contained in the compressed air output by the medical air compressor; the allowable concentration of particulate matter preset in the ventilation control database refers to the preset maximum particle concentration value in a specific ventilation control system in order to maintain the quality of the air output by the air compressor and meet the requirements of medical equipment; the allowable humidity preset in the ventilation control database refers to the maximum humidity value allowed in a specific ventilation control system in order to keep the humidity of the air output by the air compressor within an appropriate range; the functional impact index corresponding to the unit value of the air compression stability index preset in the ventilation control database indicates the degree of influence of the unit value of the air compression stability index on the functional index of the medical air compressor. The ventilation control database stores the corresponding relationship between the unit value of the air compression stability index and its corresponding functional impact index. For example, the unit value of the air compression stability index is input into the ventilation control database, and the ventilation control database can match the functional impact index corresponding to the unit value of the air compression stability index. In this embodiment, the value range is (0, 1).

[0076] In this embodiment, a lower air compression stability index will lead to unstable output of the air compressor, resulting in a decrease in the functional index of the medical air compressor; a lower real-time air pressure, even less than the preset air pressure limit, may result in other medical equipment being unable to obtain sufficient air pressure support, affecting their working effect, and further resulting in a decrease in the functional index of the medical air compressor; a higher real-time operating temperature, even higher than the preset operating allowable temperature, may accelerate the wear and aging of the internal parts of the compressor, reduce its service life, and increase energy consumption and failure rate, resulting in the medical equipment being unable to obtain a continuous air source; when the real-time flow rate is relatively large or relatively small, that is, when the degree of deviation from the preset reference flow rate is relatively large, the medical equipment is unable to obtain the required air flow; when the real-time oil content is relatively large, even when it is more than the preset allowable oil content, the internal parts of the medical equipment may be damaged. Parts are contaminated by oil, which affects their normal operation and accuracy, and thus leads to an increase in the functional indicators of medical air compressors; when the real-time particle concentration is large, or even greater than the preset allowable particle concentration, the internal parts of the medical equipment are worn by particles, reducing their service life and accuracy. For example, the ventilation effect of the ventilator may be affected by the blockage of the airway by particles; when the real-time humidity is too high or too low, that is, the degree of deviation from the preset allowable humidity is large, the normal operation and treatment effect of the medical equipment are affected. For example, the ventilator may cause dryness of the patient's respiratory tract due to insufficient humidity, increasing the risk of infection, while excessive humidity may cause excessive moisture in the airway, affecting the ventilation effect; therefore, through a detailed analysis of each parameter in the functional indicators of the medical air compressor, it can be ensured that the medical equipment obtains stable and continuous air source support to improve its operation effect and reliability.

[0077] Specifically, the final determination of whether it is necessary to issue an early warning prompt for the function of the medical air compressor is made according to the function comparison result, and the specific determination process is as follows: If the medical air compressor function index is greater than or equal to the medical air compressor function index limit value preset in the ventilation control database, the function comparison result is recorded as the first function comparison result.

[0078] If the medical air compressor function index is less than the medical air compressor function index limit value preset in the ventilation control database, the function comparison result is recorded as the second function comparison result.

[0079] If the function comparison result is the second function comparison result, it is necessary to give an early warning prompt for the function of the medical air compressor.

[0080] In this embodiment, the medical air compressor function index is compared with the medical air compressor function index limit value preset in the ventilation control database. When the medical air compressor function index is greater than or equal to the medical air compressor function index limit value preset in the ventilation control database, it means that the medical air compressor is in good working condition and the performance index reaches or exceeds the expected standard. In this case, the function comparison result can be recorded as the "first function comparison result", which usually indicates that the equipment is in normal or excellent operating condition; when the medical air compressor function index is less than the medical air compressor function index limit value preset in the ventilation control database, it means that the medical air compressor is in poor working condition and the performance index does not reach the expected standard. In this case, the function comparison result can be recorded as the "second function comparison result", which usually indicates that the equipment needs the function of the medical air compressor for early warning prompts. The specific early warning prompts can be used in the monitoring interface of the noise reduction ventilation system. The text is used for early warning prompts, such as "The operating temperature of the medical air compressor is too high. Please check the cooling system immediately and take corresponding cooling measures." Or "The medical air compressor noise is abnormal. There may be mechanical failure or vibration problems. Please stop and check immediately."

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined in this specification, they should all fall within the protection scope of the present invention.
