Description

Technical Field

[0001] The present invention relates to the technical field of xxxx, and in particular to an oxygen-enriched fresh air purification system based on lora technology. Background Art

[0002] The oxygen-enriched fresh air purification system based on LoRa technology refers to the application of LoRa wireless communication technology to various components in the oxygen-enriched fresh air purification system to achieve remote monitoring and management between devices. In the oxygen-enriched fresh air purification system based on LoRa technology, the system is mainly composed of an oxygen-enriched generator and a purifier; among them, the oxygen-enriched generator is a key component in the oxygen-enriched fresh air purification system, responsible for separating oxygen from outdoor air and increasing its concentration. Its working principle is based on molecular sieve technology, which uses molecular sieve towers to process air and transport oxygen to the room; while the indoor air purifier is responsible for purifying indoor air, removing pollutants and harmful gases, and ensuring indoor air quality. It is equipped with multiple filtration systems inside, which can effectively remove PM2.5, bacteria, viruses, formaldehyde and other harmful substances; in addition, the air purifier is equipped with intelligent sensors to monitor indoor air quality in real time, automatically adjust the working mode according to the air quality, and ensure that the indoor air is continuously fresh; the purifier continuously inhales indoor air, processes it through the filtration system, and then releases it back to the room to achieve indoor air circulation purification.

[0003] The oxygen-enriched fresh air purification system achieves a virtuous cycle of indoor and outdoor air through the coordinated work of an oxygen-enriched generator and an indoor air purifier; the oxygen-enriched generator provides oxygen-rich fresh air to increase the oxygen concentration of the indoor air and promote air circulation, while the indoor air purifier simultaneously purifies the air to remove pollutants and harmful gases to ensure fresh and healthy air; in addition, the system is also equipped with intelligent control, which automatically adjusts the working status through real-time monitoring of indoor and outdoor environmental changes, optimizes energy efficiency and improves user experience; through this design, the oxygen-enriched fresh air purification system based on LoRa technology can effectively improve indoor air quality and create a healthy and comfortable living and working environment.

[0004] When the above-mentioned oxygen-enriched fresh air purification system based on LoRa technology is working, it mainly relies on the coordinated work of the oxygen-enriched generator and the air purifier; however, the above-mentioned method often assumes that the oxygen-enriched generator and the air purifier are in good condition when the oxygen-enriched fresh air purification system based on LoRa technology is working. However, if there is a fault in the oxygen-enriched generator and the air purifier and it is not discovered in time, the oxygen-enriched fresh air purification system based on LoRa technology will still perform purification activities, which will result in the oxygen-enriched fresh air purification system based on LoRa technology. The purification effect is not good, and it may even affect the health of users, and may also increase the energy consumption of the system, and ultimately cause premature damage to the equipment and increase maintenance costs.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0041] The embodiment of the present invention provides an oxygen-enriched fresh air purification system based on lora technology. Figure 1 , Figure 1 A framework diagram of an oxygen-enriched fresh air purification system based on LoRa technology provided in an embodiment of the present invention. The system includes:

[0042] Power abnormality module: obtains the working power of the oxygen-enriched generator in the oxygen-enriched fresh air purification system when oxygen is provided, and calculates the power abnormality coefficient of the oxygen-enriched generator according to the working power of the oxygen-enriched generator;

[0043] Air inhalation abnormality module: obtains the air flow rate inhaled by the air purifier, and calculates the air inhalation abnormality coefficient according to the air flow rate inhaled by the air purifier;

[0044] Collaborative abnormality module: obtains the oxygen concentration output by the oxygen enrichment generator and the inhaled flow rate of the air purifier to calculate the collaborative abnormality coefficient between the oxygen enrichment generator and the air purifier;

[0045] Purification judgment module: obtain the fault coefficient according to the power abnormality coefficient, the air intake abnormality coefficient and the coordinated abnormality coefficient, and judge whether to stop the oxygen-enriched fresh air purification system according to the fault coefficient and the preset fault coefficient threshold.

[0046] Based on an embodiment of the present invention, an oxygen-enriched fresh air purification system based on LoRa technology is provided. The power abnormality coefficient of the oxygen-enriched generator is calculated by obtaining the working power of the oxygen-enriched generator in the oxygen-enriched fresh air purification system when providing oxygen; the air flow rate inhaled by the air purifier is obtained to calculate the air intake abnormality coefficient; the oxygen concentration output by the oxygen-enriched generator and the intake flow rate of the air purifier are obtained to calculate the coordinated abnormality coefficient between the oxygen-enriched generator and the air purifier; the fault coefficient is obtained according to the power abnormality coefficient, the air intake abnormality coefficient and the coordinated abnormality coefficient, and it is determined whether to stop the oxygen-enriched fresh air purification system according to the fault coefficient and the preset fault coefficient threshold; in this way, when the oxygen-enriched fresh air purification system based on LoRa technology is working, the faults of the oxygen-enriched generator and the air purifier can be analyzed and determined, and it is determined whether the oxygen-enriched fresh air purification system based on LoRa technology can perform purification activities, thereby ensuring that the oxygen-enriched fresh air purification system based on LoRa technology has a good purification effect, will not affect the health of users, and reduce the energy consumption of the system, see Sharp maintenance cost.

[0047] In one embodiment, obtaining the working power of the oxygen-enriched generator in the oxygen-enriched fresh air purification system when providing oxygen, and calculating the power abnormality coefficient of the oxygen-enriched generator according to the working power of the oxygen-enriched generator includes:

[0048] Obtain the working power of the oxygen-enriched generator and obtain a power sequence based on time sequence;

[0049] The power in the power series is calibrated as Q w , w represents the order number of the power in the power sequence, w=1, 2, 3, 4, ..., u, u is the total number of powers in the power sequence, and u is a positive integer;

[0050] Compute the mean of the power series The calculation formula is:

[0051] Calculate the power abnormality coefficient using the following formula:

[0052]

[0053] Among them, HY is the power abnormality coefficient.

[0054] It should be noted that in the oxygen-enriched fresh air purification system, the working power of the oxygen-enriched generator can be obtained through the power sensor installed on the equipment. The sensor monitors the current and voltage of the oxygen-enriched generator in real time and calculates the power consumption of the equipment according to the power formula. Through these real-time data, the system can continuously track the working status of the oxygen-enriched generator, so as to detect power anomalies in time and ensure the efficient operation of the system. If the power exceeds the normal range, it may indicate that the equipment is faulty or the efficiency is reduced, and further inspection and maintenance are required.

[0055] It should be noted that in the oxygen-enriched fresh air purification system, the greater the working power fluctuation of the oxygen-enriched generator when providing oxygen, the greater the corresponding power abnormality coefficient, which means that the oxygen-enriched generator is more likely to fail. If the oxygen-enriched fresh air purification system based on LoRa technology is still performing purification activities, it will lead to poor purification effect of the oxygen-enriched fresh air purification system based on LoRa technology, and even affect the health of users. It may also increase the energy consumption of the system, and ultimately lead to premature damage to the equipment and increase maintenance costs. The reason is that the power fluctuation of the oxygen-enriched generator reflects the instability of its operating state, which may indicate that internal components such as compressors, molecular sieves or electronic control systems have failed or worn. The increase in the power abnormality coefficient indicates that the output efficiency of the oxygen-enriched generator is reduced, the oxygen concentration is unstable, and the fresh air system cannot continuously provide the required oxygen-enriched air. If the system continues to operate, the oxygen concentration in the air may not meet the expected standards, thereby affecting the indoor air quality, resulting in a significant decrease in the purification effect, and even the generation of harmful gases or pollutants. In addition, the operation of the oxygen-enriched generator in a faulty state will lead to unnecessary energy waste, increase power consumption and increase operating costs. Long-term operation will accelerate the aging of the equipment, shorten the service life of the equipment, and eventually lead to premature damage to the equipment, resulting in high maintenance and replacement costs. Therefore, timely detection and shutdown to deal with faults is the key to ensuring efficient and safe operation of the system.

[0056] In one implementation, the benefit of analyzing the working power fluctuation of the oxygen-enriched generator for judging whether the oxygen-enriched fresh air purification system based on LoRa technology can be purified is: analyzing the working power fluctuation of the oxygen-enriched generator helps to promptly discover abnormalities in the operation of the equipment, thereby ensuring that the oxygen-enriched fresh air purification system based on LoRa technology will not continue to perform purification activities when it is in poor condition. Large power fluctuations usually indicate that there is a fault in the equipment or the efficiency is reduced. By monitoring this change, early warning and processing can be carried out at the early stage of the problem to prevent the system from continuing to work when the oxygen supply is unstable, prevent the air quality from not meeting the standard, and thus protect the health of users. In addition, the analysis of power fluctuations can also optimize the energy efficiency management of the system, reduce unnecessary energy waste, reduce operating costs, and improve the reliability and life of the system. By accurately judging the working status of the oxygen-enriched generator, it is possible to ensure that the system operates in the best condition, avoid equipment damage and high maintenance costs caused by faults, thereby improving the overall user experience and the economy of the system.

[0057] In one embodiment, obtaining the air flow rate sucked in by the air purifier and calculating the air inhalation abnormality coefficient according to the air flow rate sucked in by the air purifier includes:

[0058] The actual inhaled air flow data of the air purifier at different time points is obtained through an air flow sensor to obtain an inhaled air flow sequence based on time sequence;

[0059] The intake air flow rate in the intake air flow rate sequence is calibrated as S d , d represents the sequence number of the intake air flow in the intake air flow sequence, d=1, 2, 3, 4, ..., k, k is the total number of the intake air flow in the intake air flow sequence, and k is a positive integer;

[0060] Calculating the absolute difference between each intake air flow in the intake air flow sequence and a preset standard intake air flow, and obtaining the deviation between the intake air flow at a corresponding moment and the preset standard intake air flow;

[0061] The air intake abnormality coefficient is calculated based on the deviation between the intake air flow rate at all times and the preset standard intake air flow rate. The calculation formula is: Where DF is the air intake abnormality coefficient, and SW is the preset standard intake air flow rate.

[0062] It should be noted that in the oxygen-enriched fresh air purification system, the actual air flow rate of the air purifier at different time points can be obtained through the flow sensors installed in the equipment. These sensors can monitor the air flow rate at the air inlet of the air purifier in real time and transmit the data to the system for processing. By collecting and recording the flow data at each time point, the system can derive a time series that reflects the amount of air inhaled by the air purifier during operation; in addition, the preset standard intake air flow rate is set by the factory staff based on the actual performance of the air purifier, and no specific restrictions or elaborations are made.

[0063] It should be noted that in the oxygen-enriched fresh air purification system, the larger the inhalation abnormality coefficient of the air purifier when providing oxygen, the greater the possibility of a malfunction of the oxygen-enriched generator. If the oxygen-enriched fresh air purification system based on LoRa technology is still performing purification activities, the purification effect of the oxygen-enriched fresh air purification system based on LoRa technology will be poor, and it may even affect the health of users. It may also increase the energy consumption of the system and ultimately cause premature damage to the equipment and increase maintenance costs. The reason is that an increase in the inhalation abnormality coefficient of the air purifier usually means that the air intake flow rate of the equipment is significantly different from the preset standard, which may be due to a blockage in the filtration system, a decrease in fan efficiency, or a sensor failure. When these problems are not discovered and handled in time, the air purifier cannot normally inhale and process indoor air, resulting in the inability to effectively purify the air quality. If the oxygen-enriched fresh air purification system continues to operate at this time, the oxygen-enriched generator may continue to provide oxygen-enriched air, but since the air purifier cannot effectively filter and purify the air, the overall purification effect of the system will be greatly reduced, and the pollutants and harmful substances remaining in the air will affect the health of users. At the same time, the system may need to increase power to maintain operation, resulting in unnecessary energy consumption and increased equipment wear, which may eventually cause premature damage to the equipment, leading to frequent repairs and maintenance, and increased operating costs. Therefore, timely monitoring and diagnosis of the air purifier's inhalation abnormality coefficient is crucial to ensure efficient and stable operation of the system.

[0064] In one implementation, the benefits of analyzing the inhalation abnormality coefficient of the air purifier for judging whether the oxygen-enriched fresh air purification system based on LoRa technology can be purified are as follows: analyzing the inhalation abnormality coefficient of the air purifier has important benefits for judging whether the oxygen-enriched fresh air purification system based on LoRa technology can be purified; first, the inhalation abnormality coefficient can reflect the working status of the air purifier in real time. If there is a deviation, the system can identify and take countermeasures in time. This real-time monitoring capability ensures the efficient operation of the air purifier and avoids poor air purification effect caused by equipment failure. Secondly, by comparing with the preset standard flow rate, the system can identify abnormal fluctuations in the air purifier's inhaled air flow, thereby early detection of potential equipment failures, such as filter blockage or fan problems, to avoid these problems from causing system energy efficiency to decline or fault spread; finally, based on the remote monitoring and data transmission capabilities of LoRa technology, these anomalies can be quickly fed back to the management platform, and remote diagnosis and adjustment can be carried out in time, reducing the need for manual intervention and improving the system's automation and user experience; this analysis not only helps to improve purification efficiency, but also reduces energy consumption and maintenance costs, ensuring that the oxygen-enriched fresh air purification system always maintains the best operating state.

[0065] In one embodiment, obtaining the oxygen concentration output by the oxygen enrichment generator and the inhaled flow rate of the air purifier to calculate the synergistic abnormality coefficient between the oxygen enrichment generator and the air purifier includes:

[0066] The oxygen-enriched fresh air purification system obtains the oxygen concentration E output by the oxygen-enriched generator at each time point during the period of oxygen supply. d and the actual air flow rate S of the air purifier d , d represents the sequence number of the time point, d = 1, 2, 3, 4, ..., k, k is the total number of time points, and k is a positive integer;

[0067] According to the output oxygen concentration E of the oxygen enrichment generator d and the air purifier's suction flow S d , calculate the expected oxygen supply Y d , the calculation formula is: d =E d ×S d ; Y d represents the expected oxygen supply at this time point d;

[0068] The oxygen concentration C in the air flow is obtained by installing an oxygen concentration sensor in the air purifier d , the air purifier's suction flow S d Multiply by the oxygen concentration C d Get the actual oxygen amount A of the air purifier d ;

[0069] According to the desired oxygen supply Y d and the actual amount of oxygen A d The synergistic abnormal coefficient KU between the oxygen enrichment generator and the air purifier is obtained, and the calculation formula is:

[0070] It should be noted that the oxygen concentration data output by the oxygen enriched generator at each time point is obtained through the oxygen concentration sensor of the oxygen enriched generator; the air flow data inhaled by the air purifier at each time point is obtained through the flow sensor; the oxygen concentration in the inhaled air flow is obtained through the oxygen concentration sensor in the air purifier; these data combined together can be used to calculate the expected oxygen supply and the actual oxygen amount, so as to further calculate the synergistic anomaly coefficient between the oxygen enriched generator and the air purifier.

[0071] It should be noted that in the oxygen-enriched fresh air purification system, the larger the synergistic abnormality coefficient between the oxygen-enriched generator and the air purifier when providing oxygen, the greater the possibility of a failure of the oxygen-enriched generator. If the oxygen-enriched fresh air purification system based on LoRa technology continues to perform purification activities, the purification effect of the oxygen-enriched fresh air purification system based on LoRa technology will be poor, and it may even affect the health of the user. It may also increase the energy consumption of the system, and ultimately cause premature damage to the equipment and increase maintenance costs. The reason is that the larger the synergistic abnormality coefficient between the ozone generator and the air purifier, the greater the deviation in the working efficiency and effect between the two; this deviation usually indicates that there are problems with key components of the system (such as the coordination of oxygen concentration output and air flow), which may lead to insufficient oxygen supply or a decrease in air purification effect; if the oxygen-enriched fresh air purification system continues to perform purification activities at this time, the air quality cannot be effectively improved, which may cause users to stay in an unhealthy environment, increase the burden on the respiratory system, and even cause health problems in severe cases. At the same time, the system's energy consumption will also increase due to equipment incoordination, resulting in energy waste, reduced overall system operating efficiency, further accelerated equipment aging and damage, and increased costs for frequent repairs and replacements; therefore, timely detection and identification of the synergistic abnormality coefficient between the oxygen enrichment generator and the air purifier will help prevent equipment failures and ensure efficient, safe and sustainable operation of the system.

[0072] In one implementation method, the benefit of analyzing the synergy anomaly coefficient between the oxygen-enriched generator and the air purifier for determining whether the oxygen-enriched fresh air purification system based on LoRa technology can be used for purification is as follows: by real-time monitoring of the synergy anomaly coefficient, it is possible to effectively identify whether there is a functional mismatch or failure between the oxygen-enriched generator and the air purifier, thereby ensuring that the system operates in a normal synergy state; if the synergy anomaly coefficient is large, it means that the system has a large working deviation or failure risk. At this time, the system should be shut down for inspection and repair in time to avoid continued operation resulting in a decrease in air purification effect, or energy waste due to equipment failure; in addition, timely detection and handling of synergy anomalies can not only avoid potential harm to user health, but also extend the service life of equipment, reduce maintenance costs, optimize energy consumption, and improve the overall efficiency of the system; therefore, the analysis of the synergy anomaly coefficient plays a vital role in ensuring the long-term stable operation of the system and user experience.

[0073] In one embodiment, the fault coefficient obtained according to the power abnormality coefficient, the air intake abnormality coefficient and the coordinated abnormality coefficient includes:

[0074]

[0075] Wherein, GHT is the fault coefficient, HY, DF and KU are the power abnormality coefficient, air intake abnormality coefficient and coordinated abnormality coefficient respectively, a1, a2 and a3 are the preset proportional coefficients of HY, DF and KU respectively, and a1, a2 and a3 are all greater than 0.

[0076] It should be noted that a1, a2, and a3 are set by professionals according to actual conditions. Generally, the sum of a1, a2, and a3 is 1. For example, a1, a2, and a3 can be 0.2, 0.4, and 0.4 respectively. They can also be other numbers without specific limitations. In addition, before calculating the fault coefficient, it is necessary to remove the unit from the power abnormal coefficient, the air intake abnormal coefficient, and the coordinated abnormal coefficient.

[0077] In one embodiment, judging whether to stop the oxygen-enriched fresh air purification system according to the fault coefficient and the preset fault coefficient threshold includes:

[0078] If the fault coefficient is not less than the preset fault coefficient threshold, it means that the oxygen-enriched generator and air purifier of the oxygen-enriched fresh air purification system based on LoRa technology have failed, and the oxygen-enriched fresh air purification system needs to be stopped;

[0079] If the fault coefficient is less than the preset fault coefficient threshold, it means that the oxygen-enriched generator and air purifier of the oxygen-enriched fresh air purification system based on LoRa technology have not failed, and there is no need to stop the oxygen-enriched fresh air purification system.

[0080] It should be noted that the preset fault coefficient threshold is determined by professionals based on actual conditions and is not limited or elaborated on in detail.

[0081] It should be noted that some technical parameters of the oxygen-enriched fresh air purification system based on LoRa technology are:

[0082] Rated fresh air volume: 40-120 cubic meters per hour (various models can be selected according to different house types and space requirements, such as 40m 3 / h、60m 3 / h、80m 3 / h、120m 3 / h, etc.);

[0083] The oxygen-enriched generator generates oxygen in the following ways: using advanced molecular sieve pressure swing adsorption (PSA) oxygen production technology to separate high-purity oxygen from the air;

[0084] Oxygen enrichment concentration: The indoor air can be enriched with oxygen to 23%-27%, effectively increasing the oxygen content in the indoor air, improving the breathing experience of personnel, and improving indoor work efficiency and comfort.

[0085] Oxygen production efficiency: Under standard working conditions, different models of equipment can produce 40 liters to 120 liters of oxygen per minute, meeting the needs of multiple people using it at the same time.

[0086] Purification performance:

[0087] Primary filtration: The primary filter is the primary filter of the air purifier, mainly used to filter dust particles larger than 5 microns, including large particles of dust, burrs, pollen, floating objects and other pollutants.

[0088] High-efficiency filtration (HEPA): H13 grade HEPA filter, the filtration efficiency is up to ≥99.97% for tiny particles of 0.3μm and above, such as PM2.5, bacteria, viruses, etc.

[0089] Negative ion release: releases a large number of negative ions. Negative ions are due to the addition of an outer electron to oxygen molecules, which gain negative charges and therefore have extraordinary binding ability; they cause indoor floating dust, smoke, germs, and viruses that usually carry positive charges to gather together, lose the ability to float freely in the air, and fall quickly, thereby purifying the air; purifying the environment and no longer causing harm to the human body. These ultrafine particles are difficult to filter out using general mechanical equipment; and air negative ions have a special ability to capture these harmful substances. The smaller the particle size, the higher the capture rate, which is an effective way to eliminate these pollutions.

[0090] Noise Level:

[0091] Low wind speed operation noise: ≤30 dB(A). At night or when running at low load, the noise is almost imperceptible and does not affect the rest and work of indoor personnel.

[0092] High wind speed operation noise: ≤60 dB(A). Even at the maximum fresh air volume output, the noise is controlled within a relatively comfortable range, meeting the noise standard requirements for office buildings and other places.

[0093] Energy consumption: Rated power: 1500-3750 watts (power varies for different air volume models). It adopts high-efficiency energy-saving motors and optimized circuit design to reduce energy consumption while ensuring system performance, meeting energy-saving standards.

[0094] Intelligent control: Air quality monitoring: Built-in high-precision PM2.5, PM1.0 and other air quality sensors to monitor indoor air quality in real time.

[0095] Automatic mode: When the automatic button is touched, the negative ion and sterilization lamp are turned on, and the motor position is automatically adjusted according to the air quality detection data to ensure that the indoor air is always kept in a high-quality state. When the air quality exceeds the standard, the fresh air volume and purification intensity are automatically increased; when the air quality is good, the operating power is automatically reduced to save energy and reduce consumption.

[0096] In one implementation method, through the above-mentioned design principles, the oxygen-enriched fresh air purification system can effectively improve the indoor air quality and provide users with a healthy and comfortable living and working environment.

[0097] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be used to artificially limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
