[0056] See also Figure 1 As shown, in some embodiments of the present application, this embodiment provides a central automatic disinfection spray system, including:

[0057] A spray master station, a valve group, a nozzle, a sensor group, a monitoring device and a control device; the spray master station is connected to the valve group, and the spray master station is used to store and mix disinfectants; the valve group is connected to the nozzle, and the valve group is used to control the flow of the disinfectant; there are several nozzles; the sensor group includes several temperature sensors, humidity sensors and particle concentration sensors; the nozzles, the sensor group and the monitoring device are all arranged in the dairy processing workshop, and the monitoring device is used to monitor personnel situation data; the control device is connected to the spray master station, the valve group, the nozzle, the sensor group and the monitoring device, and the control device includes a determination module, a judgment module, an adjustment module and a storage module;

[0058] The determination module is configured to collect the total area of ​​the dairy processing workshop and the height of each nozzle from the ground of the dairy processing workshop, and determine the initial spray parameters of each nozzle according to the total area and the height; wherein the initial spray parameters include the initial spray volume and the initial spray time interval;

[0061] The storage module is configured to store the injection influencing factor.

[0062] It can be seen that the central automatic disinfection spray system provided in the embodiment can achieve fully automated disinfection, effectively cover every corner of the workshop, and ensure the uniformity and thoroughness of the disinfection effect. Through real-time monitoring and intelligent adjustment, the system can automatically optimize the spray parameters according to the environmental changes and personnel activities in the workshop, thereby achieving the purpose of saving disinfectants and improving disinfection efficiency.

[0063] It can be understood that the spray main station is used to store and mix disinfectants to ensure a stable supply of disinfectants and a suitable mixing ratio; the valve group, as an intermediate link connecting the spray main station and the nozzle, needs to ensure that the flow of the disinfectant can be accurately controlled. In some embodiments, the valve group includes solenoid valves, which can respond to the instructions of the control device and quickly open or close, thereby achieving accurate control of the spray volume and spray time interval; the nozzle is used to spray disinfectants; the sensor group is a key part of the system for real-time monitoring of environmental conditions; the temperature sensor, humidity sensor and particle concentration sensor can provide real-time environmental data in the workshop, which are crucial for determining whether the spray parameters need to be adjusted; the monitoring device is responsible for collecting the activities of personnel in the workshop, including the number of personnel and the length of stay, which are equally important for the system to determine whether the spray parameters need to be adjusted; the control device is the core of the entire system, and it realizes intelligent control of the spray system through the collaborative work of various modules; the mutual cooperation of the determination module, the judgment module, the adjustment module and the storage module ensures that the system can dynamically adjust the spray parameters according to real-time data to achieve the best disinfection effect. In summary, the central automatic disinfection spray system of this embodiment not only improves the disinfection efficiency, but also reduces the amount of disinfectant used, achieving a dual improvement in environmental protection and economic benefits.

[0064] Specifically, the spray master station includes:

[0065] The liquid storage tank 110 has a discharge pipe 170 at the bottom;

[0066] A high and low liquid level gauge 120 is located at the top of the liquid storage tank 110 and extends into the liquid storage tank 110;

[0067] A water inlet pipe 130 is connected to the top of the liquid storage tank 110;

[0068] The liquid inlet pipe 140, the liquid outlet pipe 150 and the pneumatic double diaphragm pump 160, one end of the liquid inlet pipe 140 is connected to the bottom end of the liquid storage tank 110, and the other end of the liquid inlet pipe 140 is connected to one end of the pneumatic double diaphragm pump 160; the other end of the pneumatic double diaphragm pump 160 is connected to the liquid outlet pipe 150.

[0069] It is understandable that the other end of the liquid outlet pipe 150 is connected to the discharge pipe 170 of the spray main station. The liquid storage tank 110 can store enough disinfectant to meet the needs of continuous disinfection operations. The high and low liquid level gauge 120 is used to monitor the disinfectant level in the liquid storage tank 110 to ensure that the system can replenish the disinfectant in time to prevent the continuity of the disinfection operation from being affected by insufficient disinfectant. The water inlet pipe 130 is used to replenish the disinfectant in the liquid storage tank 110, while the liquid inlet pipe 140, the liquid outlet pipe 150 and the pneumatic double diaphragm pump 160 together constitute the disinfectant delivery system to ensure that the disinfectant can be accurately delivered from the liquid storage tank 110 to the spray main station. In this embodiment, the pneumatic double diaphragm pump 160 is a commonly used pumping equipment, which uses compressed air as a power source to deliver fluids through the reciprocating motion of the diaphragm. This pump has the characteristics of simple structure, easy maintenance, strong corrosion resistance, etc., and is very suitable for conveying liquids such as disinfectants that may corrode the pump body.

[0070] Specifically, when determining the initial spray parameters of the nozzle based on the total area and height, it includes:

[0071] The initial injection volume is obtained by the following formula:

[0072]

[0073] The initial injection time interval is obtained by the following formula:

[0074]

[0075] Wherein, Qi represents the initial spray volume of the i-th nozzle; A represents the total area; N represents the total number of nozzles; Hi represents the nozzle height of the i-th nozzle; Ci represents the spray capacity coefficient of the i-th nozzle; T represents the initial spray interval; i=1, 2, 3...N.

[0076] It is understandable that the spray capacity coefficient Ci is pre-set according to the spray range and spray intensity of the nozzle to ensure that each nozzle can evenly cover the area it is responsible for in the initial state. In actual applications, the spray capacity coefficient of the nozzle may need to be adjusted according to the degree of wear, blockage or other factors of the nozzle to ensure the consistency of the spray effect. The nozzle height Hi refers to the vertical distance from the nozzle to the ground. This parameter is crucial to determining the spray volume and spray coverage. The height of the nozzle setting needs to take into account the spatial layout and spray effect in the workshop to ensure that the disinfectant can effectively cover every corner of the workshop.

[0077] In this embodiment, the spray master station, valve group, nozzle, sensor group, monitoring device and control device are all connected through a network to form an intelligent central automatic disinfection spray system. The network connection makes the data exchange and instruction transmission between the various components fast and accurate, thereby improving the response speed and control accuracy of the system.

[0078] Specifically, the environmental data of each monitoring area is collected, and the initial spray parameters are determined based on the environmental data, including:

[0079] Environmental data includes temperature data, humidity data and air quality index;

[0080] The number of monitoring areas where the collected temperature data is greater than the temperature threshold is recorded as the temperature number;

[0081] The number of monitoring areas where the collected humidity data is greater than the humidity threshold is recorded as the humidity quantity;

[0082] The number of monitoring areas where the collected air quality index is greater than the air quality index is recorded as the air quality quantity;

[0083] The temperature quantity is compared with the temperature quantity threshold, the humidity quantity is compared with the humidity quantity threshold, and the air quality quantity is compared with the air quality quantity threshold, and it is determined whether to adjust the initial spray parameters according to the comparison results.

[0084] It is understandable that the temperature quantity threshold, humidity quantity threshold and air quality quantity threshold are pre-set according to the specific environmental requirements of the dairy processing workshop. These thresholds are used to determine whether the environment in the workshop has reached the level where the spray parameters need to be adjusted. For example, if the temperature quantity exceeds the temperature quantity threshold, it means that the temperature in certain areas of the workshop is too high, and the amount of disinfectant sprayed may need to be increased to ensure the disinfection effect; similarly, if the humidity quantity or air quality quantity exceeds the corresponding threshold, the spray parameters also need to be adjusted accordingly. In this way, the system can dynamically adjust the spray strategy according to the actual environmental conditions to adapt to different working conditions and ensure the efficiency and safety of the disinfection operation.

[0085] Specifically, judging whether to adjust the initial liquid injection parameters according to the comparison results includes:

[0086] When the temperature quantity is greater than a temperature quantity threshold and / or the humidity quantity is greater than a humidity quantity threshold and / or the air quality quantity is greater than an air quality quantity threshold, determining to adjust the initial liquid injection parameters;

[0087] When the temperature quantity is less than or equal to the temperature quantity threshold, the humidity quantity is less than or equal to the humidity quantity threshold, and the air quality quantity is less than or equal to the air quality quantity threshold, it is determined that the initial liquid injection parameters are not adjusted.

[0088] It can be understood that through the intelligent adjustment of the adjustment module, the system can ensure the pertinence and efficiency of the disinfection operation, while reducing unnecessary waste of disinfectants and achieving optimal allocation of resources.

[0089] Specifically, the calculation of the spraying impact factor based on the personnel quantity data, personnel stay time data and environmental data in each monitoring area includes:

[0090] The spray influence factor is obtained by the following formula:

[0091]

[0092] Among them, F represents the spray impact factor, P represents the total number of people in all monitoring areas; Ts represents the average residence time of people in all monitoring areas; Et represents the temperature environment impact value; Eh represents the humidity environment impact value; Ea represents the air quality index environment impact value; α represents the quantity weight coefficient; β represents the residence time weight coefficient; γ represents the environment weight coefficient.

[0093] It can be understood that α, β, and γ represent the importance weights of the number of personnel, residence time, and environmental factors in the calculation of the spray influencing factors. These weight coefficients are determined based on actual disinfection needs and experience to ensure that the system can comprehensively consider the influence of personnel activities and environmental conditions when calculating the spray influencing factors. For example, if there are a large number of people in the workshop, the system will increase the spray volume to ensure the disinfection effect; if the personnel stay for a long time, the system will also increase the spray volume, because a long stay means a higher risk of contamination; and changes in environmental factors such as temperature, humidity, and air quality index will also affect the spray volume through the corresponding environmental impact value. Through this calculation method, the system can comprehensively consider multiple factors to achieve precise control of the spray volume, thereby achieving the best disinfection effect.

[0094] In this embodiment, the value of α is preferably 0.5, the value of β is preferably 0.3, and the value of γ is preferably 0.2.

[0095] Specifically, the spraying influencing factors are compared with historical data, and the adjustment coefficients of the initial spraying parameters are determined based on the comparison results, including:

[0096] When there is a historical spraying influence factor that is the same as the spraying influence factor in the historical data, the initial spraying parameters are adjusted according to the historical adjustment coefficient corresponding to the historical spraying influence factor;

[0097] When there is no historical spraying influence factor identical to the spraying influence factor in the historical data, the frequency of personnel staying in each monitoring area is calculated, and the adjustment coefficient is obtained according to the frequency of personnel staying, and the initial spraying parameters are adjusted.

[0098] It is understandable that when there are historical spraying influencing factors that are the same as the spraying influencing factors in the historical data, it indicates that the system has encountered similar environments and personnel activities before, so the historical experience can be directly used to adjust the spraying parameters. This adjustment method based on historical data can reduce the calculation burden of the system while improving the accuracy and efficiency of the adjustment. When there is no situation that is the same as the current spraying influencing factor in the historical data, the system needs to calculate the frequency of personnel stay through real-time monitoring data and obtain the adjustment coefficient accordingly. The calculation of the frequency of personnel stay takes into account the stay time and activity patterns of personnel in different monitoring areas, thereby providing a more accurate basis for the adjustment of spraying parameters. In this way, the system can ensure that the optimal disinfection effect can be achieved under a variety of working conditions.

[0099] Specifically, the frequency of personnel staying in each monitoring area is calculated, and the adjustment coefficient is obtained according to the frequency of personnel staying to adjust the initial spray parameters, including:

[0100] Extract the frequency of personnel stay in all monitoring areas, and obtain the maximum frequency of personnel stay and the average frequency of personnel stay;

[0101] Subtract the maximum personnel stay frequency from the average personnel stay frequency to obtain the stay frequency difference;

[0102] The dwell frequency difference is compared with a first dwell frequency difference threshold and a second dwell frequency difference threshold, and an adjustment coefficient is determined according to the comparison result; wherein the first dwell frequency threshold is smaller than the second dwell frequency threshold.

[0103] Specifically, when determining the adjustment coefficient based on the comparison results, it includes:

[0104] Presetting an adjustment coefficient interval, the adjustment coefficient interval includes a first adjustment coefficient, a second adjustment coefficient and a third adjustment coefficient;

[0105] When the dwell frequency difference is less than the first dwell frequency difference threshold, determining the adjustment coefficient to be the first adjustment coefficient;

[0106] When the dwell frequency difference is greater than or equal to the first dwell frequency difference threshold and less than the second dwell frequency difference threshold, determining the adjustment coefficient to be the second adjustment coefficient;

[0107] When the dwell frequency difference is greater than or equal to the second dwell frequency difference threshold, the adjustment coefficient is determined to be the third adjustment coefficient.

[0108] It can be understood that the first adjustment coefficient, the second adjustment coefficient and the third adjustment coefficient correspond to three different personnel stay frequencies of low, medium and high, respectively, and the first adjustment coefficient is smaller than the second adjustment coefficient, and the second adjustment coefficient is smaller than the third adjustment coefficient. When the difference in stay frequency is small, it indicates that the activities of personnel in the workshop are relatively scattered. At this time, the first adjustment coefficient can be used to reduce the amount of spray to save resources; on the contrary, if the difference in stay frequency is large, it means that the activities of personnel in certain areas are relatively concentrated. At this time, the third adjustment coefficient should be used to increase the amount of spray to ensure the disinfection effect. In this way, the system can flexibly adjust the spray strategy according to the actual situation of personnel activities, which not only ensures the disinfection effect, but also avoids the waste of resources.

[0109] Specifically, the adjustment coefficient includes a liquid spraying amount adjustment coefficient and a liquid spraying interval adjustment coefficient, and the adjustment coefficient, the liquid spraying amount adjustment coefficient and the liquid spraying interval adjustment coefficient satisfy the following relationship:

[0110] Ch=θv×Cv+θt×Ct;

[0111] Among them, Ch represents the adjustment coefficient; Cv represents the injection amount adjustment coefficient, and Cv>1; Ct represents the injection interval adjustment coefficient, and 0<Ct<1; θv represents the injection amount weight coefficient; θt represents the injection interval weight coefficient, and θv+θt=1.

[0112] It can be understood that the spray volume weight coefficient θv and the spray interval weight coefficient θt are pre-set according to the relative importance of the spray volume and the spray interval in the disinfection effect. The spray volume weight coefficient θv is greater than 1, which means that the adjustment of the spray volume has a greater impact on the disinfection effect, while the spray interval weight coefficient θt is between 0 and 1, indicating that the adjustment of the spray interval has a relatively small impact on the disinfection effect. By reasonably allocating these two weight coefficients, the system can dynamically adjust the spray volume and spray interval according to the actual monitored personnel activities and environmental data to achieve the best disinfection effect. For example, in areas where personnel activities are frequent and the stay time is long, the system will increase the spray volume weight coefficient θv, thereby increasing the spray volume to ensure the disinfection effect; while in areas where personnel activities are less, the spray interval weight coefficient θt may be increased to extend the spray interval to save the use of disinfectants. Through this flexible adjustment mechanism, the system can not only effectively respond to the disinfection needs of different areas, but also realize the rational use of resources, and further improve the efficiency and economy of disinfection operations.

[0113] In this embodiment, the value of θv is preferably 0.7, and the value of θt is preferably 0.3.
