Description

Technical Field

[0001] The present invention relates to the field of air purification management, and in particular to an indoor air purification management system based on data collection and analysis. Background Art

[0002] Modern office buildings, hospitals, residences, apartments, and schools often use highly enclosed tower-like structures to improve energy efficiency. While these structures offer excellent thermal insulation, natural ventilation is limited because the entire building is primarily ventilated through air conditioning circulation systems. This significantly reduces the building's air renewal rate, leading to a deterioration in indoor air quality. Studies have shown that without good ventilation, indoor air pollution is 2 to 5 times more serious than outdoor air pollution, and even dozens of times more serious in special cases. The deterioration of indoor air quality creates favorable conditions for the growth of microorganisms such as bacteria and viruses. The widespread use of air-conditioning systems will also lead to an increase in the concentration of inhalable particulate matter indoors. Inhalable particulate matter PM2.5 in indoor air can remain suspended for a long time and can be easily inhaled by the human respiratory system. These particles can carry biologically active pollutants such as bacteria and viruses. The suspension time of particles in the air is inversely proportional to their size, that is, the smaller the particle size, the longer the suspension time. Inhalable particles that have absorbed microorganisms such as bacteria and viruses can remain suspended in the air for a long time. Once inhaled, they can penetrate deep into the lung tissue and cause harm to human health. At present, indoor air pollution has become an "invisible killer" that endangers health. Currently, existing ventilation systems are primarily operated at a set power level, and once set, the power level is generally not frequently changed. Consequently, when indoor or outdoor air quality changes, the ventilation system is unable to respond effectively, resulting in insufficient ventilation system operation and poor indoor air quality. In response to the above technical problems, this application proposes a solution. Summary of the Invention

[0003] In the present invention, by collecting gas environment data and performing real-time feedback adjustment on the operation of the air purification equipment according to the gas environment, the operating status of the air purification equipment is adjusted in real time, achieving high-precision identification of pollution and automatic optimization of the operation strategy, solving the problem that the ventilation system cannot perform effective feedback adjustment according to the air quality and the operation effect lacks visual presentation, thereby causing the indoor air quality to deteriorate, and proposing an indoor air purification management system based on data collection and analysis.

[0004] The purpose of the present invention can be achieved through the following technical solutions: An indoor air purification management system based on data collection and analysis, comprising a purification collection unit, a change analysis unit, an effect feedback unit, a comprehensive control unit, and an operation statistics unit. The purification collection unit is capable of collecting indoor gas environment data, obtaining multiple sets of gas environment-related parameters, and sending the gas environment-related parameters to the change analysis unit and the comprehensive control unit; The integrated control unit obtains multiple sets of gas environment related parameters, analyzes the multiple gas environment related parameters through a preset gas analysis model, generates corresponding customized gas purification parameters, and sends the gas purification parameters to the operation statistics unit and the effect feedback unit; The change analysis unit collects statistics on the gas environment related parameters obtained each time, performs difference calculation based on the statistical results, obtains the gas environment change parameters, and sends the gas environment change parameters to the effect feedback unit; The effect feedback unit compares the gas environment change parameter with the gas purification parameter, generates a change coupling signal or a change abnormality signal according to the comparison result, and sends the change coupling signal or the change abnormality signal to the operation statistics unit; The operation statistics unit can obtain gas purification parameters through the comprehensive control unit, and obtain the change coupling signal or change abnormal signal through the effect feedback unit, calculate the proportion of the gas purification parameters, change coupling signal and change abnormal signal, and thus obtain the operation evaluation result.

The purification collection unit performs arithmetic averaging on the multiple groups of gas humidity data and uses the arithmetic average result as the ambient gas humidity.

[0006] As a preferred embodiment of the present invention, the gas environment-related parameters obtained by the integrated control unit include the impurity content in the gas and the ambient gas humidity. The integrated control unit simulates and analyzes the impurity content in the gas and the ambient gas humidity through formula analysis to obtain air purification parameters, wherein the air purification parameters include dust removal power and drying power; After the integrated control unit generates the corresponding dust removal power and drying power, the gas filter component in the control device operates according to the corresponding dust removal power and drying power.

[0007] As a preferred embodiment of the present invention, the change analysis unit records the ambient gas humidity and the impurity content in the gas obtained for the first time, and performs difference calculation on the corresponding parameters when obtaining the ambient gas humidity and the impurity content in the gas for the second time to obtain the ambient gas humidity difference and the impurity content difference in the gas; The variation analysis unit obtains the specifications of the environment in which the indoor air purification device operates, and performs an approximate calculation of the indoor volume to obtain the total amount of gas, compares the difference in ambient gas humidity with the total amount of gas to obtain a humidity variation ratio, and compares the difference in gas impurity content with the total amount of gas to obtain an impurity variation ratio; The variation analysis unit records the humidity variation ratio and the gas impurity variation ratio as gas environment variation parameters.

[0008] As a preferred embodiment of the present invention, the method in which the effect feedback unit compares the gas environment change parameter with the gas purification parameter is: The impurity change ratio in the gas environment change parameter and the dust removal power in the gas purification parameter are weighted and compared based on the results after weighted distribution to obtain the magnitude relationship between the impurity change ratio and the gas purification parameter after weight adjustment, which is recorded as the impurity purification result; The effect feedback unit weights the humidity change ratio and the drying power, and compares the results after weight distribution to obtain the size relationship between the humidity change ratio and the drying power after weight adjustment, and records it as the gas dehumidification result.

[0009] As a preferred embodiment of the present invention, after obtaining the impurity purification result and the gas dehumidification result, the effect feedback unit compares the impurity purification result with a set threshold value. If the impurity purification result is less than the set threshold value, a change unqualified signal is generated; if the impurity purification result is greater than or equal to the set threshold value, a change qualified signal is generated; The effect feedback unit compares the gas dehumidification result with a set threshold value. If the gas dehumidification result is less than the set threshold value, a change unqualified signal is generated.

[0011] As a preferred embodiment of the present invention, the operation statistics unit collects statistics on the gas purification parameters, establishes a time axis, records the changes in the gas purification parameters, and simultaneously records the change coupling signal and the change abnormal signal on the same time axis, and calculates the percentage of the total recorded results on the time axis; The specific calculation method is: The operation statistics unit records the total length of the time axis, and calculates the proportion of the duration of the change coupling signal and the change abnormal signal in the total length, respectively, to obtain the coupling proportion and the abnormal proportion, and then calculates the number of changes of the gas purification parameter, and counts the number of times the change number is distributed within the duration of the change coupling signal and the change abnormal signal, to obtain the coupling change number and the abnormal change number; The operation statistics unit uses the abnormal proportion and the number of abnormal changes as the operation evaluation result. If the abnormal proportion is greater than the set proportion or the number of abnormal changes is greater than the set standard, an operation abnormality warning is issued.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by collecting gas environment data and performing real-time feedback adjustment on the operation of the air purification equipment according to the gas environment, the operating state of the air purification equipment is adjusted in real time, achieving high-precision identification of pollution and automatic optimization of the operating strategy, avoiding the disadvantage that the equipment cannot be adaptively adjusted according to environmental changes under traditional static control. In the present invention, when collecting the gas environment, the gas is continuously extracted and uniformly analyzed based on the extracted gas, thereby expanding the amount of gas used as a sample during detection and the sample distribution range, improving the accuracy of gas environment collection and the representativeness of the sampled gas to the overall environment, and ensuring the accuracy of the gas environment collection results as the basis for feedback regulation. In the present invention, the operating parameters of the purification equipment are collected when the gas purification equipment is running, and the changes in the gas environment are analyzed at the same time. Correlation analysis is performed based on the changes in the gas environment and the operating parameters of the gas equipment, so as to evaluate the operating effect of the gas purification equipment, and actively generate early warnings and operation evaluation results when the operating effect of the gas purification equipment is insufficient.

The humidity difference of the ambient gas is compared with the total amount of gas to obtain the humidity variation ratio. The difference in gas impurity content is compared with the total amount of gas to obtain the impurity variation ratio. The change analysis unit records the humidity change ratio and the gas impurity change ratio as gas environment change parameters; The effect feedback unit compares the gas environment change parameter with the gas purification parameter. The method by which the effect feedback unit compares the gas environment change parameter with the gas purification parameter is as follows: The impurity change ratio in the gas environment change parameter and the dust removal power in the gas purification parameter are weighted and compared based on the results after weighted distribution to obtain the magnitude relationship between the impurity change ratio and the gas purification parameter after weight adjustment, which is recorded as the impurity purification result; The effect feedback unit weights the humidity change ratio and the drying power, and compares the results after weight distribution to obtain the relationship between the humidity change ratio and the drying power after weight adjustment, which is recorded as the gas dehumidification result, specifically: Assign weights a and b to the humidity change ratio and drying power respectively, and record the humidity change ratio and drying power as A and B. The gas dehumidification results are obtained, and the impurity purification results are the same; After obtaining the impurity purification result and the gas dehumidification result, the effect feedback unit compares the impurity purification result with the set threshold value.

Otherwise, a change abnormality signal is generated. The effect feedback unit sends the change coupling signal or the change abnormality signal to the operation statistics unit. The operation statistics unit sends the change coupling signal and the change abnormality signal through the network, thereby realizing the operation status reminder of the air purification equipment through the change abnormality signal. Example
