DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0031] See also Figure 1-13 The present invention provides a technical solution: an indoor ventilation control system based on artificial intelligence, comprising a main pipeline 1, a plurality of branch pipelines 2, a blower device 3 and a control system, wherein a detection module 21 is provided in the branch pipeline 2 for detecting the carbon dioxide concentration and temperature and humidity of the gas circulating in the corresponding branch pipeline 2, a fixed wind plate 22 is provided at the interface between the branch pipeline 2 and the main pipeline 1, and a plurality of wind holes 221 are provided on the fixed wind plate 22, a sliding wind plate 11 is provided at the interface between the main pipeline 1 and the branch pipeline 2, and a plurality of wind holes 111 are provided on the sliding wind plate 11, and a driving module is connected to the sliding wind plate 11, and the blower device 3 is connected to the main pipeline 1, and the control system is used to collect the detection data of the detection module 21 for analysis and control the ventilation process;

[0032] Supplementary explanation based on the above structure is as follows: wind hole 1 221 corresponds to wind hole 2 111 one by one. In the initial state, wind hole 1 221 and wind hole 2 111 are in an overlapping state. At this time, the ventilation area is the largest. When the sliding wind plate 11 is controlled by the driving module and translates relative to the fixed wind plate 22, wind hole 1 221 and wind hole 2 111 are staggered, and the ventilation area is reduced accordingly. The size of the ventilation area is adjusted according to the detection result of the detection module 21.

[0033] like Figure 7 As shown, the branch pipeline 2 is located on one side of the fixed wind plate 22 and is penetrated by a disinfection pipe 4. The disinfection pipe 4 is a hollow pipe structure, and a blocking block 41 is movably arranged inside. A screw 42 is rotatably connected to one side of the blocking block 41, and one end of the screw 42 is connected to the driving module. A plurality of atomizing nozzles 43 are arranged on the disinfection pipe 4, and the feed port of the atomizing nozzle 43 is connected to the disinfection pipe 4.

[0034] In actual operation, the driving module is used to control the length of the screw 42 in the disinfection tube 4, so as to adjust the number of the atomizing nozzles 43 blocked by the blocking block 41, and finally adjust the spraying amount of the disinfectant.

[0035] One end of the disinfection tube 4 is connected to the infusion tube 5 , the infusion tube 5 is connected to a liquid pump 51 , and the inlet end of the liquid pump 51 is connected to a disinfectant storage tank 52 .

[0036] The driving module includes a group of slide rails 60, screw rod 2 61, wheel 1 62, wheel 2 63, wheel 3 64, shaft 65, support block 66 and motor 67, wherein the slide rails 60 are arranged on both sides of the sliding wind plate 11 and cooperate with it, screw rod 2 61 is penetrated on both sides of the sliding wind plate 11 and both ends are rotatably arranged on the side wall of the main pipeline 1, wheel 1 62 is sleeved on screw rod 2 61, wheel 2 63 is rotatably arranged on the outer wall of the main pipeline 1 and corresponds to wheel 1 62, wheel 3 64 is arranged corresponding to wheel 2 63, shaft 65 is fixed at both ends of wheel 3 64 and rotatably cooperates with support block 66, shaft 65 is threadably matched with screw rod 1 42, support block 66 is fixed on the outer wall of the main pipeline 1, and motor 67 is connected to one of wheel 2 63.

[0037] In one embodiment, the first wheel 62, the second wheel 63, and the third wheel 64 are connected to each other through pulleys, and the motor 67 controls the rotation of the two second wheels 63. First, the movement of the sliding air plate 11 is controlled by the rotation of the screw 42. Secondly, the third wheel 64 drives the rotating shaft 65 to rotate, and indirectly drives the screw 42 to move, so as to adjust the length of the screw 42 extending into the disinfection tube 4. Furthermore, the ventilation area is made corresponding to the amount of disinfectant sprayed. When the ventilation area is the largest, the air flow is the largest, and the required disinfectant is also the largest. At this time, the length of the screw 42 extending into the disinfection tube 4 is the shortest, so that all the atomizing nozzles 43 can spray normally; as the ventilation area gradually decreases, the length of the screw 42 extending into the disinfection tube 4 gradually increases, so that the number of atomizing nozzles 43 that can spray normally gradually decreases, and they are connected and corresponding to each other.

[0038] Further, such as Figures 8 to 11 As shown, a screening assembly is provided in the branch pipeline 2, and the screening assembly includes a screen 70, two groups of fixed plates 71, a plurality of springs 72 and a processing pipeline 73, wherein the fixed plates 71 are fixed on the inner wall of the branch pipeline 2 at intervals, and the two ends of the spring 72 are respectively connected to the screen 70 and the fixed plates 71, and the upper and lower sides of the screen 70 are connected to slide plates 74, and the branch pipeline 2 is provided with a slide groove 23 to cooperate with the slide plate 74. The branch pipeline 2 is located at the upper and lower side openings of the screen 70, and the two ends of the processing pipeline 73 are respectively connected to the upper and lower side openings of the branch pipeline 2.

[0039] The supplementary explanation based on the above structure is as follows: In the initial state, the screen 70 is located in the middle of the opening of the branch pipeline 2, and the two slides 74 completely block the openings on the upper and lower sides. According to the different directions of the airflow, the screen 70 is pushed to slide to one side, and the impurities in the airflow are intercepted on the other side of the screen 70. For example, when used to extract the original gas in the room, the airflow flows from the branch pipeline 2 to the main pipeline 1, and the screen 70 is affected by the air inlet direction and moves toward the main pipeline 1, and the impurities in the airflow are blocked on the side of the screen 70 facing the branch pipeline 2, while the opening of the branch pipeline 2 connecting to the processing pipeline 73 is exposed; similarly, when used to transport fresh air to the room, the airflow flows from the main pipeline 1 to the branch pipeline 2, and the screen 70 is affected by the air inlet direction and moves toward the branch pipeline 2, and the impurities in the airflow are blocked on the side of the screen 70 facing the main pipeline 1, while the opening of the branch pipeline 2 connecting to the processing pipeline 73 is exposed.

[0040] like Fig.13 As shown, a secondary fan 731 and a sieve plate 732 are provided in the processing pipeline 73. Preferably, the secondary fan 731 is located on the upper side of the branch pipeline 2, and the sieve plate 732 is located on the lower side of the processing pipeline 73. The processing pipeline 73 is externally connected to the lower side of the sieve plate 732 with respect to the output pipeline.

[0041] In actual operation, the secondary fan 731 is used to deliver airflow to the surface of the screen 70 to clean impurities on the surface of the screen 70 to avoid blockage. The airflow carries the impurities and enters from the lower opening of the branch pipeline 2. The impurities are blocked by the screen plate 732, and the remaining airflow continues to circulate. The impurities accumulated on the lower side of the screen plate 732 will be pumped out of the processing pipeline 73 by the external output pipeline after a period of time.

[0042] The control system includes an information acquisition module, a data analysis module and an execution module, wherein the information acquisition module includes an internal data detection unit and an external information input unit, the internal data detection unit is used to collect the gas carbon dioxide concentration, temperature and humidity detected by the detection module 21 corresponding to the branch pipeline 2, the external information input unit is used to record the date and shopping mall activities, the data analysis module is used to combine the data of the internal data detection unit and the external information input unit to analyze and predict the indoor air status, and output the corresponding processing plan, and the execution module is used to execute the processing results of the data analysis module.

[0043] Specifically, the external information input unit is used to determine the daily flow of people in the mall. By recording the date, the daily working days and weekends are classified. By default, the flow of people on daily working days is small, the ventilation demand is small, and the ventilation level is Ⅰ a Level, there are more people on weekends and holidays, and the ventilation demand is high, so the ventilation level is II a Enter the shopping mall activities, classify the overall activities and individual activities, and make secondary classifications of the ventilation needs of the spaces where each merchant is located according to the shopping mall activities. Those who do not participate in the overall activities and have no individual activities are classified as I b Class II, that is, the ventilation demand is the lowest, only overall activities or only individual activities are b Category III: There are both overall and individual activities b Class, ventilation needs are highest.

[0044] Furthermore, based on the above analysis results, real-time adjustments are made in combination with the carbon dioxide concentration and temperature and humidity detected by the detection module 21. At the same time, the detection results of the detection module 21 can be used to identify whether there is an abnormal fire at the location of the merchant, that is, the detected carbon dioxide concentration and temperature values ​​are much higher than normal values. Timely warnings can be given while increasing the gas extraction force to help extract the upper layer of smoke generated by the fire, avoid smoke blocking the field of vision and endangering human health, thereby assisting personnel in evacuating.

[0045] Based on the above description, if Fig.14As shown in the figure, in order to better purify the air, an anion generator 8 is added to each branch pipeline 2. Anions can adsorb harmful substances such as dust, bacteria, and viruses in the air, combine with the harmful substances in the air and agglomerate into clusters, causing them to sink, thereby achieving the purpose of purifying the air. A visual detection module 9 is added to the processing pipeline 73. Under the set normal ventilation state, the amount of anions introduced into the room by each branch pipeline 2 each time is a fixed value M.

[0046] During the process of extracting the original indoor gas, the visual detection module 9 records the state of impurity accumulation at the bottom of the processing pipeline 73 in each cycle. That is, after a single exhaust cycle is completed, the secondary fan 731 is turned off, the passage between the processing pipeline 73 and the branch pipeline 2 is closed, and the impurities inhaled into the processing pipeline 73 begin to precipitate and accumulate at the bottom of the processing pipeline 73. The visual detection module 9 scans the bottom of the processing pipeline 73, evaluates the amount of impurities n based on the comprehensive impurity coverage area and height, and determines whether the amount of impurities is within the ideal range of 0 to N. If a is always less than or equal to N, the amount of anions introduced each time can meet the requirements, and most of the impurities in the gas have been adsorbed and precipitated. If n is greater than N, the amount of anions introduced cannot meet the need to purify the air. In the next ventilation cycle, the amount of anions introduced is increased. The actual increase amount m is related to the amount of impurities and the limit value of the ideal range, and the difference and the increase amount show a progressive relationship, that is, m = Q(n - N), where Q is a proportionality coefficient set by humans;

[0047] Specifically, taking a working day as an example, the ventilation level is Ⅰ a When it is, the amount of anions introduced into the room by each merchant each time is set as a fixed value M a . On this basis, for merchants in category Ⅰ b , the amount of anions introduced remains unchanged; for merchants in category Ⅱ b , the amount of anions introduced is adjusted to 1.5M a ; for merchants in category Ⅲ b , the amount of anions introduced is adjusted to 2M a .

[0048] Furthermore, the amount of anions introduced is adjusted in combination with the amount of impurities n. The personnel flow is proportional to the amount of impurities n.

[0049] For merchants in category Ⅰ b , the personnel flow is small, and the amount of impurities n should be within the ideal range:

[0050] When 0 ≤ n ≤ N, the indoor personnel flow of category Ⅰ b merchants is normal, and the ventilation system operates normally;

[0051] When N < n ≤ 1.2N, for category Ⅰ bFor Class I merchants, the indoor footfall is relatively more than the ideal state but still within the allowable normal range. The ventilation system is operating normally and the input amount of negative oxygen ions is relatively increased according to the increase in n.

[0052] When n > 1.2N, for Class I b merchants, the indoor footfall is abnormal. While increasing the input amount of negative oxygen ions, the ventilation system should notify the mall official to locate the abnormal merchant for verification.

[0053] For Class II b merchants, the personnel flow should be more than that of Class I b merchants, and the impurity quantity n may exceed the ideal range:

[0054] When 0 ≤ n ≤ 1.2N, for Class II b merchants, the indoor footfall is normal and the ventilation system is operating normally.

[0055] When 1.2N < n ≤ 1.5N, for Class II b merchants, the indoor footfall is relatively more than the ideal state but still within the allowable normal range. The ventilation system is operating normally and the input amount of negative oxygen ions is relatively increased according to the increase in n.

[0056] When n > 1.5N, for Class II b merchants, the indoor footfall is abnormal. While increasing the input amount of negative oxygen ions, the ventilation system should notify the mall official to locate the abnormal merchant for verification.

[0057] For Class III b merchants, the personnel flow should be more than that of Class II b merchants, and the impurity quantity n will exceed the ideal range:

[0058] When 0 ≤ n < 0.8N, for Class III b merchants, the indoor footfall is small. The ventilation system is operating normally and the input amount of negative oxygen ions is relatively decreased according to the decrease in n.

[0059] When 0.8N ≤ n ≤ 1.5N, for Class III b merchants, the indoor personnel flow is in a normal state. The ventilation system is operating normally and the input amount of negative oxygen ions is relatively increased according to the increase in n.

[0060] When n > 1.5N, for Class III b merchants, the indoor personnel flow is excessive. While the ventilation system is operating normally, it should remind the mall official whether additional personnel need to be dispatched to the designated merchant to maintain order.

[0061] The above values are for exemplary illustration, and the specific range values are adjusted according to actual needs.

The indoor ventilation control system based on artificial intelligence according to claim 8 is characterized in that: The external information input unit is used to determine the daily flow of people in the mall. By recording the date, the daily working days and weekends are classified. The default is that the flow of people on daily working days is small, the ventilation demand is small, and the ventilation level is I. a Level, there are more people on weekends and holidays, and the ventilation demand is high, so the ventilation level is II a Enter the shopping mall activities, classify the overall activities and individual activities, and make secondary classifications of the ventilation needs of the spaces where each merchant is located according to the shopping mall activities. Those who do not participate in the overall activities and have no individual activities are classified as I b Class II, that is, the ventilation demand is the lowest, only overall activities or only individual activities are b Category III: There are both overall and individual activities b Class, ventilation needs are highest.

10. The indoor ventilation control system based on artificial intelligence according to claim 9, characterized in that: Each of the branch pipes (2) is provided with a negative oxygen ion generator (8), and the processing pipe (73) is provided with a visual detection module (9). Under normal ventilation conditions, the amount of negative oxygen ions introduced into the room through the branch pipe (2) each time is set to a fixed value M; In the process of extracting the original indoor gas, the visual detection module (9) records the state of impurity accumulation at the bottom of the processing pipeline (73) in each cycle, that is, after one ventilation cycle is completed, the secondary fan (731) is turned off, the passage between the processing pipeline (73) and the branch pipeline (2) is closed, and the impurities sucked into the processing pipeline (73) begin to precipitate and accumulate at the bottom of the processing pipeline (73). The visual detection module (9) scans the bottom of the processing pipeline (73), comprehensively evaluates the impurity amount n based on the impurity coverage area and height, and determines whether the impurity amount is in the ideal range of 0 to N. If a is always less than or equal to N, the amount of negative oxygen ions introduced each time can meet the demand, and most of the impurities in the gas have been adsorbed and precipitated. If n is greater than N, the amount of negative oxygen ions introduced cannot meet the need for air purification. In the next ventilation cycle, the amount of negative oxygen ions introduced is increased. The actual increase m is related to the impurity amount and the limit value of the ideal range. The difference and the increase are in a progressive relationship, that is, m=Q(nN), where Q is a proportional coefficient, which is set manually.
