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.

[0036] Embodiment 1:

[0037] See also Figure 1 to Figure 2As shown, the present invention is an air disinfection machine operation management system based on historical data analysis, including an operation management platform, a working condition information unit, a historical working condition unit, a maintenance evaluation unit, a real-time demand unit, a response supervision unit and a control management unit, the operation management platform is connected to the working condition information unit in a one-way communication, the working condition information unit is connected to the historical working condition unit and the maintenance evaluation unit in a one-way communication, the historical working condition unit and the maintenance evaluation unit are connected to the real-time demand unit in a one-way communication, the real-time demand unit is connected to the response supervision unit and the control management unit in a one-way communication, and the response supervision unit is connected to the control management unit in a one-way communication;

[0038] When the operation management platform monitors the operation of the air disinfector, a supervision instruction is generated and sent to the working condition information unit. After receiving the supervision instruction, the working condition information unit immediately collects the historical operation information and historical management information of the air disinfector, and sends the historical operation information and historical management information to the historical working condition unit and the maintenance evaluation unit respectively. After receiving the historical operation information, the historical working condition unit immediately conducts a historical operation condition supervision evaluation analysis on the historical operation information, so as to analyze it from the perspective of historical operation performance, so as to understand the abnormal risk of historical operation performance, so as to provide data support for subsequent operation management. The specific historical operation condition supervision evaluation analysis process is as follows:

[0039] The air disinfection machine operation time period is collected and set as the time threshold, and the historical operation information of the air disinfection machine within the time threshold is obtained. The historical operation information includes the operation performance index and the operation condition index. The operation performance index and the operation condition index are marked as YB and YK respectively. The operation performance index YB and the operation condition index YK are substituted into the formula LB = [YB × a1 ÷ (YK × a2)] 2 ×a3 to obtain the historical operation evaluation coefficient, where a1 and a2 are the preset proportional factor coefficients of the operation performance index and the operation condition index respectively. The proportional factor coefficient is used to correct the deviation of various parameters in the formula calculation process, so as to make the calculation result more accurate. a3 is the preset fault tolerance factor coefficient. a1, a2 and a3 are all greater than zero. LB is the historical operation evaluation coefficient. The historical operation evaluation coefficient LB is compared and analyzed with the preset thresholds E1 and E2 stored in the internal storage. E1<E2:

[0040] If the historical operation evaluation coefficient LB>E2, it is judged as the first-level state;

[0041] If the historical operation evaluation coefficient E1≤LB≤E2, it is judged to be in the second level state;

[0042] If the historical operation evaluation coefficient LB<E1, it is determined to be a level 3 state, wherein the abnormal operation performance risks corresponding to the level 1 state, level 2 state and level 3 state decrease in sequence, and the level 1 state, level 2 state and level 3 state are set as historical operation index YZ, YZ=3, 2, 1, that is, the historical operation index YZ=3, indicating the level 1 state, the historical operation index YZ=2, indicating the level 2 state, and the historical operation index YZ=1, indicating the level 3 state;

[0043] In the embodiment of the present invention, the operation performance index indicates the total duration corresponding to the operation performance coefficient in the total number of times the air disinfector operates. The operation performance coefficient indicates the duration corresponding to the value of the operation parameter exceeding the preset threshold value during a single operation. The operation parameters include abnormal sound, vibration amplitude, etc. It should be noted that the larger the value of the operation performance index, the higher the subsequent operation management requirements;

[0044] In the embodiment of the present invention, the operation condition index analysis process is as follows: a rectangular coordinate system is established with the historical operation times of the air disinfector as the X-axis and the operation efficiency index as the Y-axis, and an operation efficiency index curve is drawn by plotting points, and the mean between the maximum peak value and the minimum trough value in the operation efficiency index curve is set as the operation condition index. The operation efficiency index represents the ratio between the single operation efficiency and the single energy consumption total value. It should be noted that the larger the value of the ratio between the operation efficiency and the total energy consumption value, the better the operation condition performance of the air disinfector, the smaller the abnormal risk, the larger the value of the operation condition index, and the lower the operation management demand of the air disinfector;

[0045] After receiving the historical management information, the maintenance assessment unit conducts a comprehensive operation and maintenance assessment analysis on the historical management information, so as to analyze it from the two points of maintenance and repair, so as to understand the potential impact level of historical maintenance and repair on the operation of the air disinfector, so as to provide data support for subsequent analysis. The specific operation and maintenance comprehensive assessment analysis process is as follows:

[0046] Obtain the historical management information of the air disinfection machine within the time threshold. The historical management information represents the maintenance management coefficient and the repair assessment coefficient. The maintenance management coefficient and the repair assessment coefficient are labeled WH and WX respectively. Substitute the maintenance management coefficient WH and the repair assessment coefficient WX into the formula The operation and maintenance impact assessment coefficient is obtained, wherein f1 and f2 are respectively preset weight factor coefficients of the maintenance management coefficient and the repair assessment coefficient, and both f1 and f2 are greater than zero, and W is the operation and maintenance impact assessment coefficient. The operation and maintenance impact assessment coefficient W is compared and analyzed with the preset operation and maintenance impact assessment coefficient interval stored internally, and the preset interference value of the operation and maintenance impact assessment coefficient W corresponding to the preset operation and maintenance impact assessment coefficient interval is set as the operation and maintenance interference factor YR. For example, if the operation and maintenance impact assessment coefficient W belongs to the first interval in the preset operation and maintenance impact assessment coefficient interval, the corresponding value is 1.2, and 1.2 is the operation and maintenance interference factor YR. If the operation and maintenance impact assessment coefficient W belongs to the second interval in the preset operation and maintenance impact assessment coefficient interval, the corresponding value is 2.4, and 2.4 is the operation and maintenance interference factor. If the operation and maintenance impact assessment coefficient W belongs to the third interval in the preset operation and maintenance impact assessment coefficient interval, the corresponding value is 2.8, and 2.8 is the operation and maintenance interference factor, and so on, and the operation and maintenance interference factor is set by personnel according to needs;

[0047] In the embodiment of the present invention, the maintenance management coefficient represents the product value obtained by multiplying the number of delayed maintenance and the total delay time in the total number of historical maintenance of the air disinfector after data normalization. It should be noted that the larger the value of the maintenance management coefficient, the greater the potential interference of maintenance;

[0048] In an embodiment of the present invention, the maintenance assessment coefficient represents the product of the historical fault duration of the air disinfector and the total number of parts replacements after data normalization processing, and the historical fault duration represents the time between the time when the fault indication occurs and the time when the fault repair is completed. It should be noted that the larger the value of the maintenance assessment coefficient, the greater the potential maintenance impact of the air disinfector.

[0049] Embodiment 2:

[0050] The real-time demand unit is used to collect the start and stop condition information of the air disinfector, and conduct real-time management demand supervision evaluation and analysis on the start and stop condition information to determine whether the air disinfector needs to be managed during its actual operation, that is, to analyze from the two points of automatic start and stop and operation efficiency of the air disinfector, and to analyze in combination with the historical operation index and operation and maintenance interference factor to improve the accuracy of the analysis results. The specific real-time management demand supervision evaluation and analysis process is as follows:

[0051] The historical operation index YZ and operation and maintenance interference factor YR of the air disinfector within the time threshold are obtained, and the start and stop working condition information of the air disinfector within the time threshold is obtained. The start and stop working condition information includes the strain evaluation value and the working condition performance value. The management demand evaluation coefficient is obtained according to the formula H=[(YZ×v1+YR×v2)×YB×v3÷(GB×v4)]×v5, where YB represents the strain evaluation value, GB represents the working condition performance value, v1, v2, v3 and v4 are respectively the preset proportional coefficients of the historical operation index YZ, the operation and maintenance interference factor YR, the strain evaluation value YB and the working condition performance value GB, v5 is the error correction factor coefficient, v1, v2, v3, v4 and v5 are all greater than zero, H is the management demand evaluation coefficient, and the management demand evaluation coefficient H is compared and analyzed with the preset management demand evaluation coefficient threshold value stored in its internal input:

[0052] If the ratio between the management demand assessment coefficient H and the preset management demand assessment coefficient threshold is less than 1, a normal signal is generated;

[0053] If the ratio between the management demand assessment coefficient H and the preset management demand assessment coefficient threshold is greater than or equal to 1, an alarm signal is generated and sent to the control management unit. After receiving the alarm signal, the control management unit immediately performs the preset early warning operation corresponding to the alarm signal, so as to perform reasonable and targeted management of the air disinfector according to the information feedback, so as to ensure the operation stability and air disinfection efficiency of the air disinfector;

[0054] In the embodiment of the present invention, the strain evaluation value represents the sum of the values ​​of the corresponding parts of the instantaneous performance characteristics corresponding to the opening or closing time of the air disinfection machine that exceed the preset threshold value. The instantaneous performance characteristics include instantaneous voltage, instantaneous abnormal sound, etc. It should be noted that the strain evaluation value represents the characteristic performance value of the air disinfection machine at the moment of starting and stopping. The larger the value of the strain evaluation value, the greater the operation risk of the air disinfection machine.

[0055] In the embodiment of the present invention, the working condition performance value represents the ratio between the actual operating efficiency of the air disinfector and the actual energy consumption value. It should be noted that the larger the value of the working condition performance value is, the smaller the operating risk of the air disinfector is and the better the disinfection effect is.

[0056] When a normal signal is generated, the response supervision unit is used to respond to the normal signal and collect the response management information of the air disinfector, and perform automatic air disinfection response performance supervision analysis on the response management information, so as to analyze from the perspective of air disinfection response when the overall operation of the air disinfector is normal, so as to reduce the impact of the disinfection response on the operation of the air disinfector. The specific automatic air disinfection response performance supervision analysis process is as follows:

[0057] The response management information of the air disinfection machine within the time threshold is obtained. The response management information includes a response deviation value and a response evaluation index. The response deviation value and the response evaluation index are compared and analyzed with the preset response deviation value threshold and the preset response evaluation index threshold stored in the internal input:

[0058] If the response deviation value is less than the preset response deviation value threshold, and the response evaluation index is less than the preset response evaluation index threshold, no signal is generated;

[0059] If the response deviation value is greater than or equal to the preset response deviation value threshold, or the response evaluation index is greater than or equal to the preset response evaluation index threshold, a control optimization signal is generated, and the control optimization signal is sent to the control management unit. After receiving the control optimization signal, the control management unit immediately performs a preset early warning operation corresponding to the control optimization signal, so as to optimize the automatic air disinfection control program of the air disinfector according to the information feedback, so as to improve the air disinfection effect of the air disinfector, and at the same time help reduce the impact of the disinfection response on the operation of the air disinfector;

[0060] In the embodiment of the present invention, the response deviation value represents the product value obtained by multiplying the corresponding number of delays in the automatic air disinfection start and stop of the air disinfection machine and the delay duration after data normalization. It should be noted that the larger the value of the response deviation value, the greater the risk of the air disinfection operation of the air disinfection machine;

[0061] In the embodiment of the present invention, the analysis process of the response evaluation index is as follows: a rectangular coordinate system is established with the number of automatic air disinfection startups of the air disinfector as the X-axis and the startup duration as the Y-axis, and a startup duration curve is drawn by plotting points, and then the difference between the maximum peak value and the minimum trough value in the startup duration curve is obtained, and it is set as the response evaluation index. It should be noted that the larger the value of the response evaluation index, the greater the response optimization demand;

[0062] In summary, the present invention analyzes from two dimensions, historical operation and historical operation and maintenance, to understand the impact level of historical operation and historical operation and maintenance on the operation and control of the air disinfector, and analyzes from the two points of maintenance and repair in historical operation and maintenance to improve the comprehensiveness of data analysis, and conducts real-time management demand supervision and evaluation analysis on the start-stop operating condition information by means of information feedback to determine whether management is required during the actual operation of the air disinfector, that is, from the two points of automatic start-stop and operation efficiency of the air disinfector, and combines the historical operation index and the operation and maintenance interference factor for analysis to improve the accuracy of the analysis results, so as to reasonably and targetedly manage the air disinfector according to the information feedback to ensure the operating stability and air disinfection efficiency of the air disinfector, and further perform automatic air disinfection response performance supervision analysis on the response management information in a progressive manner, that is, when the overall operation of the air disinfector is normal, analyze from the perspective of air disinfection response, so as to optimize the automatic air disinfection control program of the air disinfector according to the information feedback to improve the air disinfection effect of the air disinfector, and at the same time help reduce the impact of the disinfection response on the operation of the air disinfector.

[0063] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0064] The above formulas are obtained by collecting a large amount of data for software simulation and selecting a formula that is close to the actual value. The coefficients in the formula are set by technical personnel in this field according to actual conditions. The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited to this. Any technical personnel familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, make equivalent replacement or change, which should be covered within the protection scope of the present invention.
