Description

Technical Field

[0001] The present invention relates to the technical field of multi-parameter coordinated control, and in particular to a multi-parameter coordinated control method and system based on a kimchi fermentation process. Background Art

[0002] Kimchi is a sour pickled food made by lactic acid bacteria fermentation. It is a custom of making and eating kimchi all over the world. Kimchi fermentation mainly utilizes the anaerobic respiration of lactic acid bacteria. Lactic acid bacteria are a type of anaerobic bacteria. Under anaerobic conditions, they can decompose the sugars in vegetables into lactic acid. In the early stage of fermentation, some microorganisms attached to the surface of vegetables, such as Enterobacter and yeast, will also participate in the fermentation. Enterobacter can use the sugars and oxygen in vegetables to produce a small amount of lactic acid, acetic acid and carbon dioxide.

[0003] However, in the prior art, it is impossible to accurately analyze the sealing of the container during the kimchi fermentation process, so that the feasibility of the fermentation process cannot be ensured, and the fermentation process cannot be monitored and analyzed, and the diffusion efficiency of the auxiliary material concentration cannot be guaranteed. In addition, it is impossible to monitor the environmental parameters in the container and perform multi-parameter coordinated control.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems and to propose a multi-parameter coordinated control method and system based on the kimchi fermentation process.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A multi-parameter coordinated control system based on a kimchi fermentation process, comprising a fermentation control platform, wherein the fermentation control platform is communicatively connected with a sealing analysis unit, a concentration diffusion analysis unit and an environmental parameter monitoring unit;

[0008] The sealing analysis unit performs sealing analysis on the kimchi container, and infers whether the fermentation process execution environment of the current kimchi container is qualified through the container sealing analysis. After the sealing monitoring is qualified, the concentration diffusion analysis unit monitors and analyzes the execution efficiency of the fermentation process, and infers whether the concentration diffusion efficiency of the auxiliary materials in the kimchi container after the corresponding auxiliary materials of the fermentation process are added meets the actual process requirements; and after the concentration diffusion analysis of the fermentation process is normal, the environmental parameter monitoring unit monitors the environmental parameters of the kimchi container.

[0009] As a preferred embodiment of the present invention, the process of the sealing analysis unit is as follows:

[0010] The sealing information is collected, and the sealing analysis coefficient of the kimchi container during the fermentation process is obtained through calculation. If the sealing analysis coefficient of the kimchi container during the fermentation process exceeds the sealing analysis coefficient threshold, a high sealing signal is generated and sent to the fermentation regulation and control platform; if the sealing analysis coefficient of the kimchi container during the fermentation process does not exceed the sealing analysis coefficient threshold, a low sealing signal is generated and sent to the fermentation regulation and control platform.

[0011] As a preferred embodiment of the present invention, the sealing information includes the constant duration of the internal pressure value of the container when the kimchi container is not fermented, the deviation between the recovery value of the internal pressure value of the container after the fermentation process of the kimchi container is completed and the pressure value before execution, and the maximum deviation between the average value of the corresponding container pressure when the process is executed during the period when the kimchi container is not fermented and the average value of the corresponding container pressure during the period when the fermentation process is not executed.

[0012] As a preferred embodiment of the present invention, the process of the concentration diffusion analysis unit is as follows:

[0013] The concentration deviation information and concentration fluctuation information are obtained. If the concentration deviation information exceeds the maximum concentration deviation threshold, or the concentration fluctuation information exceeds the deviation shortening speed threshold, a diffusion inefficiency signal is generated and sent to the fermentation regulation and control platform; if the concentration deviation information does not exceed the maximum concentration deviation threshold, and the concentration fluctuation information does not exceed the deviation shortening speed threshold, a diffusion high-efficiency signal is generated and sent to the fermentation regulation and control platform.

[0014] As a preferred embodiment of the present invention, the concentration deviation information and the concentration fluctuation information are respectively the maximum concentration deviation value of the auxiliary material concentration added after the fermentation process is executed at any position in the kimchi container corresponding to the concentration of the auxiliary material, and the shortening speed of the concentration deviation corresponding to any position after the fermentation process is executed.

[0015] As a preferred embodiment of the present invention, the process of the environmental parameter monitoring unit is as follows:

[0016] Internal and external environmental data are collected. If the internal environmental data exceeds the constant frequency threshold and the external environmental data does not exceed the pH deviation threshold, an environmental parameter abnormal signal is generated and sent to the fermentation regulation platform; if the internal environmental data does not exceed the constant frequency threshold, or the external environmental data exceeds the pH deviation threshold, a normal environmental parameter signal is generated and sent to the fermentation regulation platform.

[0017] As a preferred embodiment of the present invention, the internal environmental data and the external environmental data are respectively the constant frequency of the internal and external temperature difference at the same time corresponding to the internal temperature floating period of the container and the external temperature floating period during the fermentation stage of the kimchi container, and the numerical deviation between the internal pH of the container and the preset pH of the current progress when the fermentation process is executed during the fermentation stage of the kimchi container.

[0018] A multi-parameter coordinated control method based on kimchi fermentation process, the specific coordinated control method is as follows:

[0019] Sealing analysis: Conduct sealing analysis on kimchi containers to infer whether the fermentation process execution environment of the current kimchi container is qualified;

[0020] After the concentration diffusion analysis and sealing monitoring are qualified, the fermentation process execution efficiency is monitored and analyzed to infer whether the concentration diffusion efficiency of the auxiliary materials in the kimchi container after the corresponding auxiliary materials are added in the fermentation process meets the actual process requirements;

[0021] After the environmental parameter monitoring and concentration diffusion analysis performed in the fermentation process are normal, the environmental parameter monitoring of the kimchi container is carried out.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, the sealing performance of the kimchi container is analyzed, and the container sealing performance analysis is used to infer whether the fermentation process execution environment of the current kimchi container is qualified, thereby ensuring the execution efficiency of the fermentation process in the kimchi container and avoiding abnormal sealing performance of the kimchi container, which causes the fermentation process in the kimchi container to fail to achieve the preset effect and reduces the kimchi fermentation preparation efficiency;

[0024] The efficiency of the fermentation process is monitored and analyzed to infer whether the diffusion efficiency of the auxiliary material concentration in the kimchi container after the corresponding auxiliary materials are added to the fermentation process meets the actual process requirements, so as to ensure the efficiency of the fermentation process and ensure the efficient execution of the fermentation process. When the fermentation process is inefficient, auxiliary processes can be carried out to improve the work efficiency of kimchi fermentation.

[0025] 2. In the present invention, environmental parameters of the kimchi container are monitored, and environmental parameters are monitored on the premise that the air tightness and concentration diffusion efficiency are normal, so that the fermentation process strategy is effectively and accurately monitored, which facilitates timely adjustment of the fermentation process and improves the success rate of kimchi manufacturing.

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.

[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] See also Figure 1 As shown, a multi-parameter coordinated control system based on a kimchi fermentation process includes a fermentation control platform, wherein the fermentation control platform is communicatively connected with a sealing analysis unit, a concentration diffusion analysis unit and an environmental parameter monitoring unit;

[0032] The fermentation control platform generates a sealing analysis signal and sends the sealing analysis signal to the sealing analysis unit. After receiving the sealing analysis signal, the sealing analysis unit performs a sealing analysis on the kimchi container, and infers whether the fermentation process execution environment of the current kimchi container is qualified through the container sealing analysis, thereby ensuring the execution efficiency of the fermentation process in the kimchi container and avoiding abnormal sealing of the kimchi container, which causes the fermentation process in the kimchi container to fail to achieve the preset effect, thereby reducing the kimchi fermentation preparation efficiency;

[0033] Obtain the constant duration of the internal pressure value of the kimchi container when the non-fermentation process is executed, and mark the constant duration of the internal pressure value of the kimchi container when the non-fermentation process is executed as HDS;

[0034] Obtain the deviation between the value of the pressure inside the container restored after the kimchi container fermentation process is completed and the value of the pressure before the execution, and mark the deviation between the value of the pressure inside the container restored after the kimchi container fermentation process is completed and the value of the pressure before the execution as YPC;

[0035] The maximum deviation value between the mean pressure of the container when the process is executed during the period when the kimchi container does not have a fermentation process and the mean pressure of the container when the process is executed after the fermentation process is completed is obtained, and the maximum deviation value between the mean pressure of the container when the process is executed during the period when the kimchi container does not have a fermentation process and the mean pressure of the container when the process is executed after the fermentation process is completed is marked as YJC; the fermentation process is a process for adding auxiliary materials to the kimchi process, and the container needs to be opened, so it has an impact on the pressure in the container;

[0036] The above collected data are uniformly marked as sealing information, and substituted into the formula to obtain the sealing analysis coefficient of the kimchi container during fermentation, where the formula is: , where FG is the sealing analysis coefficient during the fermentation process of kimchi container, dwa1, dwa2 and dwa3 are all preset proportional coefficients, and α is used as the error correction factor, with a value of 0.98;

[0037] Compare the airtightness analysis coefficient of the kimchi container during fermentation with the airtightness analysis coefficient threshold:

[0038] If the sealing analysis coefficient of the kimchi container exceeds the sealing analysis coefficient threshold during the fermentation process, it is inferred that the sealing analysis of the kimchi container is qualified, a high sealing signal is generated and sent to the fermentation control platform. After receiving the high sealing signal, the fermentation control platform adjusts the execution time of the fermentation process of the kimchi container, that is, monitors the sealing in real time, and executes the fermentation process according to the high sealing period;

[0039] If the sealing analysis coefficient of the kimchi container does not exceed the sealing analysis coefficient threshold during the fermentation process of the kimchi container, it is inferred that the sealing analysis of the kimchi container is unqualified, a low sealing signal is generated and sent to the fermentation control platform. After receiving the low sealing signal, the fermentation control platform repairs the current kimchi container to control the sealing performance and readjusts the execution strategy of the current fermentation process;

[0040] At the same time, a concentration diffusion analysis signal is generated and sent to a concentration diffusion analysis unit. After receiving the concentration diffusion analysis signal, the concentration diffusion analysis unit monitors and analyzes the execution efficiency of the fermentation process, and infers whether the concentration diffusion efficiency of the auxiliary materials in the kimchi container after the corresponding auxiliary materials of the fermentation process are added meets the actual process requirements, so as to ensure the execution efficiency of the fermentation process, ensure the efficient execution of the fermentation process, and perform auxiliary processes when the fermentation process is inefficient, so as to improve the work efficiency of kimchi fermentation;

[0041] The maximum concentration deviation value at any position in the kimchi container corresponding to the concentration of the auxiliary material added after the fermentation process is executed is obtained, and the shortening speed of the concentration deviation at any position corresponding to the concentration of the auxiliary material after the fermentation process is executed is obtained, and the maximum concentration deviation value at any position in the kimchi container corresponding to the concentration of the auxiliary material added after the fermentation process is executed and the shortening speed of the concentration deviation at any position corresponding to the concentration of the auxiliary material after the fermentation process are marked as concentration deviation information and concentration floating information, respectively, and compared with the maximum concentration deviation threshold and the deviation shortening speed threshold, respectively:

[0042] If the maximum deviation value of the concentration of the auxiliary material added after the fermentation process is executed at any position in the kimchi container exceeds the maximum concentration deviation threshold, or the shortening speed of the concentration deviation at any position of the auxiliary material concentration after the fermentation process is executed exceeds the deviation shortening speed threshold, it is inferred that the concentration diffusion analysis executed by the fermentation process is abnormal, and a diffusion inefficiency signal is generated and sent to the fermentation control platform. After receiving the diffusion inefficiency signal, the fermentation control platform performs auxiliary processes on the current fermentation process, such as performing stirring again or adding auxiliary materials.

[0043] If the maximum deviation value of the concentration of the auxiliary material added after the fermentation process is executed at any position in the kimchi container does not exceed the maximum deviation threshold value, and the shortening speed of the concentration deviation at any position of the auxiliary material concentration after the fermentation process is executed does not exceed the deviation shortening speed threshold, it is inferred that the concentration diffusion analysis executed in the fermentation process is normal, and a diffusion efficiency signal is generated and sent to the fermentation control platform;

[0044] After receiving the high-efficiency diffusion signal, the fermentation control platform generates an environmental parameter monitoring signal and sends the environmental parameter monitoring signal to the environmental parameter monitoring unit. After receiving the environmental parameter monitoring signal, the environmental parameter monitoring unit monitors the environmental parameters of the kimchi container. Under the premise of ensuring that the air tightness and concentration diffusion efficiency are normal, the environmental parameter monitoring is performed to effectively and accurately monitor the fermentation process strategy, so as to facilitate timely adjustment of the fermentation process and improve the success rate of kimchi manufacturing.

[0045] Obtain the constant frequency of the internal and external temperature difference at the same time during the internal temperature floating period of the container and the external temperature floating period in the fermentation stage of the kimchi container, and mark the constant frequency of the internal and external temperature difference at the same time during the internal temperature floating period of the container and the external temperature floating period in the fermentation stage of the kimchi container as internal environmental data;

[0046] Obtaining the numerical deviation between the pH value inside the container and the preset pH value of the current progress when the fermentation process is executed in the fermentation stage of the kimchi container, and marking the numerical deviation between the pH value inside the container and the preset pH value of the current progress when the fermentation process is executed in the fermentation stage of the kimchi container as external environment data;

[0047] And the constant frequency of the internal and external temperature difference at the same time in the internal temperature floating period of the kimchi container fermentation stage and the external temperature floating period, and the numerical deviation between the internal pH value of the container and the preset pH value of the current progress when the fermentation process is executed in the kimchi container fermentation stage are compared with the constant frequency threshold and the pH deviation threshold respectively:

[0048] If the constant frequency of the internal and external temperature difference at the same time during the internal temperature floating period of the kimchi container during the fermentation stage of the kimchi container and the external temperature floating period exceeds the constant frequency threshold, and the numerical deviation between the pH value inside the container and the preset pH value of the current progress during the fermentation process during the fermentation stage of the kimchi container does not exceed the pH value deviation threshold, it is inferred that the environmental parameter monitoring and analysis inside the kimchi container is abnormal, an environmental parameter abnormal signal is generated and sent to the fermentation control platform, and after receiving the environmental parameter abnormal signal, the fermentation control platform controls multiple parameters inside the kimchi container, that is, the temperature, pH value and other parameters are synchronously adjusted;

[0049] If the constant frequency of the internal and external temperature difference at the same time during the internal temperature floating period of the container and the external temperature floating period during the fermentation stage of the kimchi container does not exceed the constant frequency threshold, or the numerical deviation between the pH value inside the container and the preset pH value of the current progress during the fermentation process during the fermentation stage of the kimchi container exceeds the pH deviation threshold, it is inferred that the environmental parameter monitoring and analysis in the kimchi container is normal, and a normal environmental parameter signal is generated and sent to the fermentation control platform;

[0050] See also Figure 2 As shown, a multi-parameter coordinated control method based on the kimchi fermentation process, the specific coordinated control method is as follows:

[0051] Sealing analysis: Conduct sealing analysis on kimchi containers to infer whether the fermentation process execution environment of the current kimchi container is qualified;

[0052] After the concentration diffusion analysis and sealing monitoring are qualified, the fermentation process execution efficiency is monitored and analyzed to infer whether the concentration diffusion efficiency of the auxiliary materials in the kimchi container after the corresponding auxiliary materials are added in the fermentation process meets the actual process requirements;

[0053] After the environmental parameter monitoring and concentration diffusion analysis performed in the fermentation process are normal, the environmental parameter monitoring of the kimchi container is carried out.

[0054] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;

[0055] When the present invention is in use, the sealing analysis unit performs a sealing analysis on the kimchi container, and infers whether the fermentation process execution environment of the current kimchi container is qualified through the container sealing analysis. After the sealing monitoring is qualified, the concentration diffusion analysis unit monitors and analyzes the execution efficiency of the fermentation process, and infers whether the concentration diffusion efficiency of the auxiliary material in the kimchi container after the corresponding auxiliary material of the fermentation process is added meets the actual process requirements; and after the concentration diffusion analysis of the fermentation process is normal, the environmental parameter monitoring unit monitors the environmental parameters of the kimchi container.
