When i=1, the production environment control parameters at the beginning of the current control date are preset production environment control parameters; step S105, if the production environment control parameters at the i+1th moment of the current control date need to be adjusted, determine the production environment control parameters at the i+1th moment of the current control date based on the production environment data at the i-1th moment of the current control date and the production environment data at the i+1th moment of the current control date; step S106, adjust the production environment of yak milk products based on the production environment control parameters at the i+1th moment of the current control date.

[0022] According to the yak milk product production environment control method of the embodiment of the present invention, by setting up multiple bacteria detection devices in the production area and monitoring the bacteria level in real time, potential hygiene problems can be discovered and handled in a timely manner, thereby improving the safety of yak milk products and reducing food safety risks. The production environment control parameters of yak milk products are accurately adjusted according to the real-time production environment conditions, thereby improving the production efficiency and quality of yak milk products.

[0023] According to one embodiment of the present invention, in step S101, the start time of the current control date can be set to 6 o'clock on the current day, 8 o'clock on the current day, etc., and the present invention is not limited to this. A plurality of bacteria detection devices are installed at a plurality of preset locations in the production area of ​​yak milk products to detect and monitor the bacteria level in the production environment and detect the hygiene and safety of the production area.

[0024] According to an embodiment of the present invention, in step S102, it is determined whether to start the production equipment according to the bacteria data and a preset bacteria threshold.

[0025] According to one embodiment of the present invention, step S102 includes: averaging the bacterial data of multiple preset positions in the production area to obtain the average bacterial data at the start time of the current control date; determining the bacterial distribution function at the start time of the current control date based on the preset position information of multiple bacterial detection devices and the bacterial data; determining the production area pollution coefficient based on the average bacterial data, the bacterial distribution function, the bacterial data and the preset bacterial threshold; if the production area pollution coefficient is greater than or equal to the set production area pollution coefficient threshold, determining not to start the production equipment and perform disinfection in the production area of ​​yak milk products; if the production area pollution coefficient is less than the set production area pollution coefficient threshold, determining to start the production equipment.

[0026] According to one embodiment of the present invention, the bacteria data obtained by the bacteria detection devices at multiple preset positions in the production area are averaged to obtain the average bacteria data at the start time of the current control date. A coordinate system is established with the center of the production area as the coordinate origin, and the preset position information of the bacteria detection device in the coordinate system is fitted with the bacteria data to obtain a bacteria distribution function for describing the bacteria distribution status of the production area at the start time of the current control date. That is, the coordinates of any position in the production area are input into the bacteria distribution function to obtain the bacteria data at the coordinates. The pollution coefficient of the production area is an important indicator for evaluating the sanitary conditions of the production area. The larger the pollution coefficient of the production area, the more serious the sanitary conditions of the production area. If the calculated pollution coefficient of the production area is greater than or equal to the set pollution coefficient threshold of the production area, it is determined not to start the production equipment, and disinfection is performed in the production area of ​​yak milk products to reduce potential health risks. If the pollution coefficient of the production area is less than the set pollution coefficient threshold of the production area, it is determined to start the production equipment, indicating that the production area has reached the safety standard and normal production activities can be carried out.

[0027] According to one embodiment of the present invention, the pollution coefficient of the production area is determined according to the average bacteria data, the bacteria distribution function, the bacteria data and the preset bacteria threshold, including: determining the pollution coefficient of the production area according to formula (1): , (1), in, is the bacterial distribution function at the start of the current control date, is the scope of the production area, To preset the bacterial threshold, is the function value of the bacterial distribution function at the s-th preset position at the start time of the current control date (bacterial data), is the average bacterial data, S is the number of preset positions, s≤S, and s and S are both positive integers, max is the maximum value function, and min is the minimum value function.

[0028] According to one embodiment of the present invention, in formula (1), The bacterial distribution function is used to describe the distribution of bacteria in the production area at the start of the current control date. Integrate the bacterial distribution function to determine the total amount of bacteria in the production area . It is the relative difference between the total amount of bacteria in the production area and the preset bacteria threshold. The larger the relative difference, the larger the total amount of bacteria in the production area, and the more serious the sanitary condition of the production area. The smaller the relative difference, the smaller the total amount of bacteria in the production area, and the safer the sanitary condition of the production area. The difference between the maximum and minimum values ​​of the function value of the bacteria distribution function at multiple preset locations at the start of the current control date and the ratio of the average bacteria data, that is, the relative difference between the maximum value of the bacteria data and the minimum value of the bacteria data. The larger the relative difference, the more uneven the distribution of bacteria in the production area, and the higher the risk of contamination at a preset location. Among the above two items, namely the relative difference between the total amount of bacteria in the production area and the preset bacteria threshold, and the relative difference between the maximum value of the bacteria data and the minimum value of the bacteria data, the maximum value is taken as the pollution coefficient of the production area. The larger the pollution coefficient of the production area, the more serious the sanitary conditions of the production area.

[0029] In this way, the pollution coefficient of the production area can be determined by averaging the bacterial data, the bacterial distribution function, the bacterial data and the preset bacterial threshold. The severity of the sanitary condition of the production area can be judged from two aspects: the total amount of bacteria and the fluctuation of bacterial distribution, that is, the overall condition and local changes of bacteria in the production area, so as to more comprehensively reflect the sanitary condition of the production area and improve the comprehensiveness, objectivity and reliability of the pollution coefficient of the production area.

[0030] According to one embodiment of the present invention, in step S103, the interval between adjacent moments can be set to 10 minutes, 20 minutes, etc., and the present invention is not limited to this. The sensor set at the preset position is used to monitor and record the production temperature data, production humidity data, production light data and production harmful gas concentration data in the production environment. The sound level meter set in the production equipment is used to monitor and record the production noise data in the production environment.

[0031] According to one embodiment of the present invention, in step S104, the preset production environment control parameters are suitable production environment control parameters for controlling the production environment, for example, the temperature is adjusted to 26 degrees Celsius, and the noise is adjusted by controlling the power of the production equipment, and the concentration of harmful gases is adjusted by controlling the power of the ventilation system. By comparing the production environment data at the i-th moment of the current control date with the production environment data at the i-1th moment of the current control date, the production environment status at the i-th moment of the current control date can be judged, thereby determining whether the production environment control parameters at the i+1th moment of the current control date need to be adjusted.

[0032] According to one embodiment of the present invention, step S104 includes: determining the production climate vector at the i-th moment and the i-1-th moment of the current control date according to the production temperature data, the production humidity data and the production lighting data; determining the standard production climate vector according to the preset production temperature data, the preset production humidity data and the preset production lighting data; determining the production harmful gas concentration distribution function at the i-th moment and the i-1-th moment of the current control date according to the preset position information and the production harmful gas concentration data; determining whether the production environment control parameters at the i+1-th moment of the current control date need to be adjusted according to the production climate vector, the standard production climate vector, the production noise data and the production harmful gas concentration distribution function.

[0033] According to one embodiment of the present invention, the production climate vectors at the i-th moment and the i-1-th moment of the current control date are determined based on the production temperature data, the production humidity data and the production lighting data, and the production climate vector reflects the production climate conditions at a specific moment. The standard production climate vector is determined based on the preset production temperature data, the preset production humidity data and the preset production lighting data, and the standard production climate vector represents the ideal or standard production climate conditions. The preset position information is fitted with the production harmful gas concentration data to obtain a production harmful gas concentration distribution function for describing the distribution of harmful gas concentrations in the production area at the start of the current control date. Based on the production climate vector, the standard production climate vector, the production noise data and the production harmful gas concentration distribution function, the production environment conditions at the i-th moment of the current control date are judged, and it is determined whether the production environment control parameters at the i+1-th moment of the current control date need to be adjusted.

[0034] According to an embodiment of the present invention, determining whether the production environment control parameters at the i+1th moment of the current control date need to be adjusted according to the production climate vector, the standard production climate vector, the production noise data and the production harmful gas concentration distribution function includes: obtaining a first condition C1, a second condition C2 and a third condition C3 according to formula (2); (2), in, The production temperature data of the sth preset position at the i-th moment of the current control date, is the production temperature data of the sth preset position at the i-1th moment on the current control date, The production humidity data of the sth preset position at the i-th moment of the current control date, is the production humidity data of the sth preset position at the i-1th moment of the current control date, is the production lighting data of the sth preset position at the i-th moment of the current control date, is the production lighting data of the sth preset position at the i-1th moment of the current control date, is the standard value of production temperature, is the standard value of production humidity, To produce the standard value of lighting, is the production climate vector of the sth preset position at the i-th moment on the current control date, is the production climate vector of the sth preset position at the i-1th moment on the current control date, For the standard production climate vector, for The transposed vector of for The transposed vector of is the production noise data of the kth production equipment at the i-th moment on the current control date, is the production noise data of the kth production equipment at the i-1th moment on the current control date, To preset the production noise difference, is the production harmful gas concentration distribution function of the jth harmful gas at the i-th moment of the current control date, is the production harmful gas concentration distribution function of the jth harmful gas at the i-1th moment on the current control date, is the range of the production area, S is the number of preset positions, K is the number of production equipment, J is the number of types of harmful gases, s≤S, k≤K, j≤J, and s, k, j, S, K and J are all positive integers, and max is the maximum value function; when any one of the first condition C1, the second condition C2 and the third condition C3 is met, it is determined that the production environment control parameters at the i+1th moment of the current control date need to be adjusted.

[0035] According to one embodiment of the present invention, in the first condition C1 of formula (2), It is the cosine similarity between the production climate vector of the sth preset position at the i-th moment of the current control date and the standard production climate vector. The larger the cosine similarity, the closer the production temperature data, production humidity data and production lighting data of the sth preset position at the i-th moment of the current control date are to the preset production temperature data, preset production humidity data and preset production lighting data, and the better the production climate condition of the sth preset position at the i-th moment of the current control date. It is the cosine similarity between the production climate vector of the sth preset position at the i-1th moment of the current control date and the standard production climate vector. The larger the cosine similarity, the closer the production temperature data, production humidity data and production lighting data of the sth preset position at the i-1th moment of the current control date are to the preset production temperature data, preset production humidity data and preset production lighting data, and the better the production climate condition of the sth preset position at the i-1th moment of the current control date. Take the maximum value of the difference between the cosine similarities of the production climate vectors of multiple preset positions at two adjacent moments and the standard production climate vector. When the maximum value satisfies the condition of being less than or equal to 0, that is, , indicating that the production climate conditions at the i-th moment of the current control date are worse than the production climate conditions at the i-1-th moment of the current control date, and the production environment control parameters need to be adjusted, for example, adjusting the production temperature data, production humidity data and production lighting data to make them closer to the preset production temperature data, preset production humidity data and preset production lighting data.

[0036] According to one embodiment of the present invention, in the second condition C2 of formula (2), It is the average value of the difference between the production noise data of multiple production equipment at the i-th moment of the current control date and the production noise data of the production equipment corresponding to the i-1th moment of the current control date, indicating the average change of the noise data of each production equipment at the i-th moment of the current control date and the i-1th moment of the current control date. When the average value satisfies the condition that it is greater than or equal to the preset production noise difference, that is, , indicating that the noise of the production environment at the i-th moment of the current control date has increased, and the production environment control parameters need to be adjusted, for example, reducing the power of the production equipment.

[0037] According to one embodiment of the present invention, in the third condition C3 of formula (2), It is the average value of the difference between the total amount of harmful gases produced by multiple harmful gases at the i-th moment of the current control date and the total amount of harmful gases produced by the harmful gases corresponding to the i-1th moment of the current control date, indicating the average change in the total amount of harmful gases produced between the i-th moment of the current control date and the i-1th moment of the current control date. When the average value satisfies the condition of being greater than or equal to 0, that is, , indicating that the concentration of harmful gases in the production environment has increased, and the production environment control parameters need to be adjusted, for example, increasing the power of the ventilation system.

[0038] In this way, it is possible to determine whether the production environment control parameters at the i+1th moment of the current control date need to be adjusted through the production climate vector, the standard production climate vector, the production noise data and the production harmful gas concentration distribution function. When judging whether the production environment control parameters at the i+1th moment of the current control date need to be adjusted, the production environment conditions at the i-th moment of the current control date are judged from three aspects: whether the production climate conditions have deteriorated, whether the noise in the production environment has increased, and whether the concentration of harmful gases in the production environment has increased. If the conditions for adjustment are met, the production environment control parameters at the i+1th moment of the current control date are adjusted, thereby improving the rationality of the production environment control parameters.

[0039] According to one embodiment of the present invention, in step S105, if the production environment control parameters at the i+1th moment of the current control date need to be adjusted, the production environment control parameters at the i+1th moment of the current control date are determined based on the production environment data at the i-1th moment of the current control date and the production environment data at the i-1th moment of the current control date.

[0040] According to one embodiment of the present invention, step S105 includes: determining the conditions satisfied by the production environment data at the i-th moment of the current control date and the production environment data at the i-1th moment of the current control date among the first condition C1, the second condition C2 and the third condition C3; determining the loss function of the production environment control parameter model at the i-1th moment of the current control date according to the conditions satisfied by the production environment data at the i-th moment of the current control date and the production environment data at the i-1th moment of the current control date, as well as the production environment data at the i-th moment of the current control date and the production environment data at the i-1th moment of the current control date; training the production environment control parameter model at the i-1th moment of the current control date according to the loss function of the production environment control parameter model at the i-1th moment of the current control date to determine the trained production environment control parameter model at the i-th moment of the current control date; determining the production environment control parameters at the i+1th moment of the current control date according to the trained production environment control parameter model at the i-th moment of the current control date.

[0042] According to one embodiment of the present invention, in formula (3), The following two situations are expressed in the form of conditional functions. When the first condition C1 is met, it means that the production climate is poor, and the conditional function value is That is, the difference between the threshold of production climate conditions and the maximum value of the difference between the cosine similarity of the production climate vectors of multiple preset positions at two adjacent moments and the standard production climate vector is used as the loss function. In the process of training the production environment control parameter model, the gap is narrowed so that the production climate conditions meet the preset standards. When the first condition C1 is not met, the value of the above conditional function is 0, and the parameters related to the temperature, humidity and light of the production environment in the loss function do not need to be adjusted.

[0043] According to one embodiment of the present invention, in formula (3), The following two situations are expressed in the form of conditional functions. When the second condition C2 is met, it means that the noise in the production environment becomes larger, and the conditional function value is That is, the difference between the preset production noise difference and the average value of the difference between the production noise data of multiple production equipment at the i-th moment of the current control date and the production noise data of the production equipment corresponding to the i-1-th moment of the current control date is used as the loss function. In the process of training the production environment control parameter model, the difference is narrowed so that the production noise meets the preset standard. When the second condition C2 is not met, the value of the above conditional function is 0, and the parameters related to the noise of the production environment in the loss function do not need to be adjusted.

[0044] According to one embodiment of the present invention, in formula (3), The following two situations are expressed in the form of conditional functions. When the third condition C3 is met, it means that the concentration of harmful gases in the production environment increases, and the conditional function value is That is, the difference between the threshold of the total amount of harmful gases produced and the average value of the difference between the total amount of harmful gases produced by multiple harmful gases at the i-th moment of the current control date and the total amount of harmful gases produced by harmful gases corresponding to the i-1-th moment of the current control date is used as the loss function. In the process of training the production environment control parameter model, the gap is narrowed so that the concentration of harmful gases in the production environment reaches the preset standard. When the third condition C3 is not met, the value of the above conditional function is 0, and the parameters of the harmful gas concentration in the production environment in the loss function do not need to be adjusted.

[0045] According to an embodiment of the present invention, in formula (3), the above three items can be summed to obtain the loss function of the production environment control parameter model at the i-1th moment of the current control date.

[0046] In this way, the loss function of the production environment control parameter model at the i-1th moment of the current control date can be determined through the conditions satisfied by the production environment data at the i-th moment of the current control date and the production environment data at the i-1th moment of the current control date, as well as the production environment data at the i-th moment of the current control date and the production environment data at the i-1th moment of the current control date, so as to stabilize the production climate conditions, effectively reduce the noise in the production environment and the concentration of harmful gases in the production environment, improve the training efficiency, and improve the accuracy of the production environment control parameter model.

The production environment control parameters of yak milk products are accurately adjusted according to the real-time production environment conditions, thereby improving the production efficiency and quality of yak milk products. When determining the pollution coefficient of the production area, the pollution coefficient of the production area can be determined by averaging bacteria data, bacteria distribution function, bacteria data and preset bacteria thresholds. The severity of the sanitary condition of the production area is judged from two aspects: the total amount of bacteria and the fluctuation of bacteria distribution, that is, the overall condition and local changes of bacteria in the production area, so as to more comprehensively reflect the sanitary condition of the production area and improve the comprehensiveness, objectivity and reliability of the pollution coefficient of the production area. When determining whether the production environment control parameters at the i+1th moment of the current control date need to be adjusted, the production climate vector, standard production climate vector, production noise data and production harmful gas concentration distribution function can be used to determine whether the production environment control parameters at the i+1th moment of the current control date need to be adjusted. When determining whether the production environment control parameters at the i+1th moment of the current control date need to be adjusted, the production environment conditions at the i+1th moment of the current control date are determined from three aspects: whether the production climate conditions have deteriorated, whether the noise in the production environment has increased, and whether the concentration of harmful gases in the production environment has increased. If the conditions for adjustment are met, the production environment control parameters at the i+1th moment of the current control date are adjusted, thereby improving the rationality of the production environment control parameters.
