[0063] See also Figure 1 , Figure 1 A flow chart of a control method for a liquefied gas tank according to an embodiment of the present application is shown. The present application embodiment provides a control method for a liquefied gas tank with implementation steps, including:

[0064] Step S110, obtaining the environmental parameters inside the liquefied gas tank and the tank body identification of the liquefied gas tank;

[0065] Step S120, obtaining control parameters corresponding to the environmental parameters according to the environmental parameters, and obtaining a first environmental analysis model corresponding to the tank identification;

[0066] Step S130, adjusting the parameters of the first environment analysis model according to the control parameters to obtain a second environment analysis model;

[0067] Step S140, inputting the environmental parameters into the first environmental analysis model and the second environmental analysis model respectively to obtain a first coping strategy and a second coping strategy;

[0068] Step S150: If the similarity between the first response strategy and the second response strategy does not reach the preset similarity threshold, the liquefied gas tank is controlled according to the first response strategy; if the similarity between the first response strategy and the second response strategy reaches the preset similarity threshold, the liquefied gas tank is controlled according to the second response strategy.

[0069] The above five steps are described in detail below.

[0070] In step S110, the environmental parameters inside the liquefied gas tank are obtained. Environmental parameters refer to parameters representing the internal environment of the liquefied gas tank. Changes in environmental parameters represent changes in the internal environment of the liquefied gas tank. If not handled in time, some corresponding changes may occur in the liquefied gas tank, causing safety hazards during the use of the liquefied gas tank.

[0071] In some embodiments, environmental parameters include: such as liquid level parameters, pressure parameters, temperature parameters and leakage parameters. The liquid level parameters are used to indicate the liquid level of the liquid in the liquefied gas tank; the pressure parameters are used to indicate the pressure inside the liquefied gas tank; the temperature parameters are used to indicate the temperature in the liquefied gas tank; and the leakage parameters are used to indicate whether the liquefied gas tank is leaking, or the severity of the leakage.

[0072] In some embodiments, the content included in the environmental parameters can be set by the user.

[0073] A method for obtaining environmental parameters inside a liquefied gas tank.

[0074] In some embodiments, the environmental parameters can be obtained by installing sensors inside the liquefied gas tank, such as installing various types of sensors on the liquefied gas tank, which can monitor and record relevant parameters inside the liquefied gas tank and automatically generate environmental parameters.

[0075] For example, liquid level sensor: used to obtain liquid level parameters, monitor the liquid level height in the liquefied gas tank, ensure that the liquid level is within a safe range, and prevent overfilling or overemptying. Pressure sensor: used to obtain pressure parameters, measure the pressure level in the tank to detect whether there is an overpressure risk, which may cause the tank to rupture or leak. Temperature sensor: used to obtain temperature parameters, monitor the temperature in the tank, and prevent high temperature from causing dangers, such as gas expansion or chemical reactions. Leak detection sensor: used to obtain leakage parameters to detect gas leaks.

[0076] In some embodiments, the user observes the environment inside the liquefied gas tank, and based on instructions input by the user, the environmental parameters inside the liquefied gas tank are obtained.

[0077] When obtaining the environmental parameters inside the liquefied gas tank, the tank identification of the liquefied gas tank is also obtained. The tank identification of the liquefied gas tank can correspond to one tank identification for each liquefied gas tank alone, or one type of liquefied gas tank can correspond to one tank identification.

[0078] In some embodiments, one liquefied gas tank has one tank body identification, which can realize the marking of the operation information of the liquefied gas tank, such as the usage, maintenance, accident situation, etc., so as to facilitate the use of a specific processing method based on the operation information and environmental parameters of the liquefied gas tank. This specific processing method is most suitable for the operation information of the liquefied gas tank. If two liquefied gas tanks have the same environmental parameters, but the two liquefied gas tanks have different operation information, the processing methods for the two liquefied gas tanks will be different. In this way, the processing method is more suitable for the liquefied gas tank in use, so as to increase the service life of the liquefied gas tank.

[0079] In some embodiments, one type of liquefied gas tank corresponds to one tank body identification, which helps to centrally process multiple liquefied gas tanks of the same type, save computer resources, and process more efficiently. For example, if tank A and tank B are liquefied gas tanks of the same type, and tank A and tank B have the same environmental parameters, only one processing method corresponding to the environmental parameters can be obtained and implemented on tank A and tank B at the same time.

[0080] Moreover, the processing methods of the same type of liquefied gas tanks can be mutually borrowed. For example, when tank A has environmental parameters A, processing method A is used, and when tank B has environmental parameters A, processing method A is also used. No additional calculation is required, which saves computer resources and makes the processing more efficient.

[0081] In step S120, control parameters corresponding to the environmental parameters are obtained according to the environmental parameters. The control parameters are pre-set, and different environmental parameters correspond to different control parameters. While obtaining the control parameters, the corresponding first environmental analysis model is obtained according to the tank identification. The first environmental analysis model is a pre-trained algorithm model for outputting a response strategy for environmental parameters. The control parameters are used to adjust the first environmental analysis model so that the calculation method of the second environmental parameters based on the first environmental analysis model is more in line with the current environmental parameters.

[0082] In some embodiments, one environmental parameter corresponds to one control parameter.

[0083] In some embodiments, a class of environmental parameters corresponds to the same control parameters. A class of environmental parameters refers to environmental parameters that meet the same preset screening conditions.

[0084] In some embodiments, one tank identification corresponds to one first environment analysis model.

[0085] In some embodiments, a class of tank identifications corresponds to the same first environment analysis model, and a class of tank identifications refers to tank identifications that meet the same preset screening conditions.

[0086] In some embodiments, environmental parameters are collected by various sensors. The environmental parameters are sent to a central processing platform (also referred to as a carrier that carries the control method of the present application, or a type of execution subject) through an Internet of Things transmission module to which the sensor is connected. The Internet of Things transmission module uses a low-power wide area network (LoRaWAN), a cellular network, or other communication technologies suitable for industrial environments to ensure real-time and reliable transmission of environmental parameters.

[0087] The IoT transmission module is a bridge between sensors and the central processing platform. It is responsible for real-time transmission of environmental parameters to the central processing platform. The module uses Low-Power Wide-Area Network (LPWAN) technology, which is a communication technology designed specifically for IoT applications. It has the characteristics of low power consumption, long-distance transmission and high connection density.

[0088] Low-power wide-area IoT technology: LPWAN technology includes a variety of communication protocols, such as LoRaWAN, Sigfox, NB-IoT, etc. These protocols are designed for low-power, long-life devices and are suitable for industrial environments that require long-term operation and low maintenance costs. LPWAN technology enables sensor nodes to operate at extremely low energy consumption while ensuring the stability and reliability of data transmission.

[0089] The central processing platform matches the first environmental analysis model according to the tank identification: After receiving the tank identification, the central processing platform retrieves and matches the first environmental analysis model of the tank identification in the database. The first environmental analysis model is established based on historical data and experience, and is used to evaluate the safety status of the liquefied gas tank to output a response strategy.

[0090] In step S130, the obtained first environmental analysis model is adjusted according to the obtained control parameters, where these control parameters are adjustment values ​​of the first environmental analysis model and are used to optimize the accuracy of the response strategy output by the first environmental analysis model.

[0091] In some embodiments, the parameters corresponding to the control parameters in the first environment analysis model are replaced with the control parameters to obtain the second environment analysis model.

[0092] In some embodiments, the control parameters are input into the first environment analysis model, the first environment analysis model is trained according to the output value of the first environment analysis model, and the parameters of the first environment analysis model are changed to obtain the second environment analysis model.

[0093] In step S140, the environmental parameters are respectively input into the first environmental analysis model and the second environmental analysis model to obtain the first coping strategy and the second coping strategy.

[0094] In step S150, the similarity between the first response strategy and the second response strategy is compared. If the similarity between the first response strategy and the second response strategy reaches a preset similarity threshold, it means that the second environmental analysis model is relatively successful and the second response strategy is more in line with the current environmental parameters. Therefore, the second response strategy is executed on the liquefied gas tank to make corresponding adjustments to the environment inside the liquefied gas tank, or corresponding measures are executed according to the situation inside the liquefied gas tank, such as alarms, adjustment of temperature, pressure, etc.

[0095] Because the first response strategy and the second response strategy are response strategies based on the same environmental parameters, and the second environmental analysis model is obtained by slightly adjusting the first environmental analysis model. The first response strategy and the second response strategy should be similar to a certain extent. Therefore, if the similarity between the first response strategy and the second response strategy does not reach the preset similarity threshold, it means that the second environmental analysis model fails and the second response strategy has a major error. Therefore, the control executes the first response strategy on the liquefied gas tank to make corresponding adjustments to the environment in the liquefied gas tank.

[0096] In the embodiment of the present application, the components of the liquefied gas tank, such as valves, can be controlled according to the response strategy. If it is found that the safety hazard is serious and cannot be well resolved, or cannot be resolved, a warning is sent to the user according to the response strategy. It should be clear that the response strategy includes a first response strategy and a second response strategy.

[0097] Through the method provided by the embodiment of the present application, the first environmental analysis model can be obtained according to the environmental parameters in the liquefied gas tank to control the liquefied gas tank more timely and accurately according to the environmental parameters in the liquefied gas tank, so as to avoid the occurrence of some dangerous situations. In addition, the second environmental analysis model that is more in line with the environmental parameters is obtained by the control parameters corresponding to the environmental parameters, so as to obtain a coping strategy that is more in line with the environmental parameters. However, in order to avoid errors in the second environmental parameter model, because it is temporarily acquired and is not as stable as the first environmental analysis model, the environmental parameters are simultaneously input into the first environmental analysis model and the second environmental analysis model to obtain the first coping strategy and the second coping strategy. According to the similarity between the first coping strategy and the second coping strategy, it is judged whether the second environmental analysis model is accurate. If it is accurate, the second coping strategy that is more in line with the environmental parameters is used to control the liquefied gas tank. Otherwise, the first coping strategy is used to control the liquefied gas tank. While using a more suitable coping strategy as much as possible, the accuracy of the coping strategy is guaranteed. Ensure that the control of the liquefied gas tank is foolproof. The method provided by the present application can monitor the state of the liquefied gas tank in real time, and provide a coping strategy including accurate risk assessment and early warning through intelligent data processing and model adjustment. This not only improves the efficiency of safety management, but also reduces potential safety risks through precise control, thereby ensuring the continuity and safety of industrial production.

[0098] In some embodiments of the present invention, when the first environmental analysis model or the second environmental analysis model analyzes the environmental parameters according to the environmental parameters and determines that there is a safety risk in the liquefied gas tank, a safety warning strategy will be automatically generated as a response strategy. This response strategy aims to reduce or avoid potential safety accidents through preventive measures. For example, when the risk type (such as overpressure, overheating, leakage, etc.) is determined, the corresponding response strategy is generated and selected in the database. The response strategy includes but is not limited to: sending an alarm to the user, automatically starting the emergency plan, adjusting the valve opening to reduce the pressure, increasing the output of the cooling system to reduce the temperature, etc.

[0099] In some embodiments, the valve control strategy included in the response strategy is one of the core executions. The valve control strategy refers to a series of instructions for precise control of industrial-grade intelligent valves, which will guide how the valve responds to early warning signals. It can be regulated according to actual needs, and will not be described in detail here.

[0100] In some embodiments, an industrial-grade intelligent valve installed in a liquefied gas tank is a key device for executing a valve control strategy. The valve may have a built-in microprocessor and an advanced drive unit to receive instructions and perform corresponding actions.

[0101] In some embodiments, the intelligent valves installed in the liquefied gas tanks can perform refined opening and closing control according to the instructions in the response strategy, including but not limited to adjusting the opening and closing speed and angle of the valves to adapt to different safety requirements and working conditions.

[0102] In some embodiments, the smart valve actuator is designed with a millisecond response time. Once it receives an instruction generated based on a response strategy, the valve can respond quickly and take timely action to prevent or mitigate safety incidents.

[0103] In some embodiments, as time goes by, the first environmental analysis model based on deep learning will continue to learn and optimize according to new data, making the first response strategy more accurate and improving the adaptability and reliability of the present application.

[0104] In some embodiments, the first environmental analysis model is pre-trained by a deep learning model, which usually includes a multi-layer neural network and can process and analyze complex nonlinear relationships. The model can learn the operation mode of the liquefied gas tank from a large amount of sensor data and predict potential safety risks based on environmental parameters.

[0105] In some embodiments, the first environmental analysis model adjusts the model parameters to obtain the second environmental analysis model, which can use the environmental parameters as input. Using its deep learning architecture, the model will analyze the environmental parameters and identify patterns or trends that may indicate risks. The second environmental analysis model outputs a second response strategy, which indicates the safety status of the liquefied gas tank and the preventive measures that may need to be taken.

[0106] In some embodiments, the first environment analysis model and the second environment analysis model have adaptive learning capabilities and can continuously optimize themselves according to real-time data to improve the accuracy of prediction. In addition, as time goes by and data accumulates, the model can be retrained regularly to maintain its predictive ability.

[0107] See also Figure 2 , Figure 2 The present invention provides a flowchart of an environmental parameter including multiple sub-environmental parameters and obtaining control parameters corresponding to the environmental parameter according to the environmental parameter according to an embodiment of the present application. The present invention provides a step S120 of obtaining control parameters corresponding to the environmental parameter according to the environmental parameter including multiple sub-environmental parameters, including:

[0108] Step S121, determining the parameter range of each sub-environment parameter according to the parameter type corresponding to each sub-environment parameter; wherein each parameter type corresponds to multiple parameter ranges, and each parameter range has a corresponding initial control parameter;

[0109] Step S122, determining the initial control parameters corresponding to each sub-environment parameter according to the parameter range of each sub-environment parameter;

[0110] Step S123, calculating the control parameters according to the initial control parameters corresponding to each sub-environment parameter.

[0111] The above three steps are described in detail below.

[0112] In step S121, the environmental parameter includes at least one sub-environmental parameter, such as a liquid level parameter, a pressure parameter, a temperature parameter, a leakage parameter, etc. Each sub-environmental parameter belongs to a parameter type. Each parameter type corresponds to at least one parameter range interval. Each parameter range interval corresponds to an initial control parameter.

[0113] Determine the parameter type of each sub-environment parameter within the environment parameter, and then determine the parameter range interval of the sub-environment parameter within the parameter type to which it belongs.

[0114] In step S122, since each parameter range of each parameter type corresponds to an initial control parameter, taking a sub-environment parameter as an example, first determine the parameter type to which it belongs, and then determine at least one parameter range of the parameter type, and then determine the parameter range of the sub-environment parameter based on the value of the sub-environment parameter, and obtain the initial control parameter corresponding to the parameter range, that is, the initial control parameter corresponding to the sub-environment parameter.

[0115] Furthermore, through the above method, the initial control parameters corresponding to each sub-environment parameter can be determined respectively.

[0116] In step S123, the control parameters are calculated according to the initial control parameters corresponding to each sub-environment parameter.

[0117] In some embodiments, the average of all initial control parameters may be used as the control parameter.

[0118] In some embodiments, if the initial control parameters corresponding to the sub-environment parameters are the same, the initial control parameters are used as the control parameters.

[0119] See also Figure 3 , Figure 3 A flowchart of calculating control parameters according to initial control parameters corresponding to each sub-environment parameter according to an embodiment of the present application is shown. The present application embodiment provides a step S123 of calculating control parameters according to initial control parameters corresponding to each sub-environment parameter, including:

[0120] Step S1231, if the initial control parameters corresponding to the sub-environment parameters are different, then obtain the weight coefficient of each sub-environment parameter;

[0121] Step S1232: multiply the initial control parameters corresponding to each sub-environmental parameter by the weight coefficient of each environmental parameter, and use the sum of the multiplication results as the control parameter.

[0122] The above two steps are described in detail below.

[0123] In step S1231, if the initial control parameters corresponding to the sub-environment parameters are different, then using the initial control parameters corresponding to a sub-environment parameter as the control parameter will make the control parameter inaccurate, thereby affecting the accuracy of the obtained response strategy. Therefore, the weight coefficient of each sub-environment parameter is obtained, and the weight coefficient is a preset value.

[0124] In some embodiments, the weight coefficient is preset by the user according to the importance of each sub-environment parameter.

[0125] In some embodiments, if the initial control parameters corresponding to the sub-environment parameters are different, the average of all the initial control parameters is used as the control parameter.

[0126] In step S1232, the initial control parameters corresponding to each sub-environmental parameter are multiplied by the weight coefficient of each environmental parameter, and the sum of the multiplication results is used as the control parameter.

[0127] In some embodiments, the sub-environment parameters included in the environmental parameters are respectively a liquid level parameter, a pressure parameter, a temperature parameter, and a leakage parameter. The control parameters can also be obtained in the following manner. It should be clear that the liquid level parameter, the pressure parameter, the temperature parameter, and the leakage parameter are only examples, and do not limit the number of sub-environment parameters, and what kind of parameters the sub-environment parameters are. It can be completely through the first sub-environment parameter, the second sub-environment parameter, the third sub-environment parameter, the fourth sub-environment parameter, and so on.

[0128] A preset parameter range matrix is ​​obtained; wherein the parameter range matrix includes five rows and three columns, three different liquid level parameter range intervals are added to each matrix position in the first row, three different pressure parameter range intervals are added to each matrix position in the second row, three different temperature parameter range intervals are added to each matrix position in the third row, and three different leakage parameter range intervals are added to each matrix position in the fourth row. The parameter range intervals in each row are arranged in order according to the parameter size; initial control parameters corresponding to each column are added to each matrix position in the fifth row, and then the values ​​of each sub-environment parameter are compared with the parameter range matrix to generate a comparison matrix, and finally the corresponding control parameters are determined based on the comparison matrix.

[0129] In some embodiments, for the establishment of a parameter range matrix: first, create a preset parameter range matrix, which is used to define the acceptable ranges of the four sub-environment parameters of liquid level, pressure, temperature and leakage. The matrix is ​​5 rows and 3 columns, each row represents a different parameter, and each column represents a different parameter range interval. The first row represents three different parameter range intervals of the liquid level parameter, the second row represents three different parameter range intervals of the pressure parameter, the third row represents three different parameter range intervals of the temperature parameter, the fourth row represents three different parameter range intervals of the leakage parameter, and the fifth row corresponds to the initial control parameters of each column.

[0130] In some embodiments, the parameter range is sorted as follows: In the parameter range matrix, the parameter range intervals in each row need to be arranged in order of size to ensure that the values ​​of the sub-environment parameters actually monitored can be correctly matched with the preset parameter range intervals.

[0131] In some embodiments, the comparison matrix is ​​generated by comparing the sub-environment parameter number with the parameter range matrix to generate a comparison matrix. The comparison matrix is ​​used to mark which parameter range interval in the parameter range matrix each sub-environment parameter falls within.

[0132] In some embodiments, for determining the control parameters: Based on the comparison matrix, the corresponding control parameters can be determined. These control parameters are extracted from the fifth row of the parameter range matrix according to the comparison results, and they represent the adjustment values ​​that should be taken for the first environmental analysis model under the current environmental parameters.

[0133] Through the above-mentioned method for determining the control parameters based on the parameter range matrix, the liquefied gas tank safety warning system can respond to different internal environmental changes more flexibly and accurately, thereby improving the safety and reliability of the system.

[0134] In one embodiment, the step of comparing each sub-environment parameter included in the environmental parameter with the parameter range matrix to generate a comparison matrix includes:

[0135] Compare each sub-environment parameter with each parameter range interval in the parameter range matrix, determine the parameter range interval corresponding to each sub-environment parameter as the target range interval, in the parameter range matrix, retain the initial control parameters in the fifth row, eliminate all range intervals outside the target range interval, and the obtained matrix is ​​used as the comparison matrix.

[0136] Through the above-mentioned method based on the parameter range matrix and the comparison matrix, the system can flexibly respond to changes in the internal environment of the liquefied gas tank and realize the regulation of the model parameters, thereby improving the accuracy level of the safety assessment of the liquefied gas tank.

[0137] In some embodiments, based on the comparison matrix, the corresponding control parameters can be determined by the following technical means: in the comparison matrix, it is determined whether each target range interval is located in the same column. If it is located in the same column, the initial control parameters in the fifth row of the column where the target range interval is located are obtained as the corresponding control parameters.

[0138] If the target range intervals are not in the same column, a weight is assigned to each column according to the number of target range intervals in each column, and the initial control parameters in the fifth row of the column where each target range interval is located are obtained. The initial control parameters are fused and calculated according to the weights assigned to each column to obtain the fused control parameters as the corresponding control parameters.

[0139] In some embodiments, for parameter fusion calculation: each initial control parameter is fused and calculated according to the weight assigned to each column, that is, each initial control parameter. The fusion calculation can adopt a variety of methods, such as weighted average, optimization algorithm or other mathematical methods, to comprehensively consider the influence of different parameters and obtain a comprehensive control parameter.

[0140] This method of obtaining control parameters takes into account multiple aspects of the internal environment of the liquefied gas tank and provides a more comprehensive and balanced control value.

[0141] Through this method, even in the complex situation where multiple sub-environmental parameters point to different control requirements, the system can determine a control parameter that comprehensively considers various factors through weight allocation and parameter fusion, and then make reasonable adaptive adjustments to the first environmental analysis model. This makes the second response strategy more flexible and effective.

[0142] In some embodiments, after step S110, the obtained environment parameters are encrypted. Before step S120, the encrypted environment parameters need to be decrypted before use.

[0143] See also Figure 4 , Figure 4 A flowchart of encrypting the acquired environmental parameters using an encryption algorithm according to an embodiment of the present application is shown. The embodiment of the present application provides steps of encrypting the acquired environmental parameters using an encryption algorithm, including:

[0144] Step S201, obtaining a first encryption algorithm according to an encryption algorithm corresponding to the acquisition time of the environmental parameter, or obtaining a preset first encryption algorithm;

[0145] Step S202, according to the acquisition time of the environmental parameters, the encryption algorithm corresponding to the acquisition time of the environmental parameters is obtained as the second encryption algorithm, and different second encryption algorithms correspond to different times;

[0146] Step S203, using the first encryption algorithm and the second encryption algorithm as target encryption algorithms;

[0147] Step S204, encrypt the environmental parameters according to the target encryption algorithm to obtain encrypted environmental parameters.

[0148] The above four steps are described in detail below.

[0149] In step S201, a preset first encryption algorithm is obtained. The first encryption algorithm is set in advance by the user.

[0150] In some embodiments, there are multiple first encryption algorithms, each encryption algorithm corresponds to a different tank identification, and the first encryption algorithm is determined according to the tank identification.

[0151] In some embodiments, there are multiple first encryption algorithms, each encryption algorithm corresponds to a different environmental parameter type, and the first encryption algorithm is determined according to the environmental parameter type.

[0152] In some embodiments, the first encryption algorithm is an incomplete algorithm and needs to be combined with the second encryption algorithm to form a complete encryption algorithm, that is, a target encryption algorithm.

[0153] In some embodiments, the first encryption algorithm is an algorithm with a few core codes, the second encryption algorithm is a core code that can be combined with the first encryption algorithm, and the second encryption algorithm has multiple core codes.

[0154] In some embodiments, the first encryption algorithm may also be determined based on the time when the environmental parameters are acquired.

[0155] In some embodiments, the first encryption algorithm is obtained according to the encryption algorithm corresponding to the acquisition time of the environmental parameter. The acquisition time of the environmental parameter corresponds to at least one encryption algorithm. When the acquisition time of the environmental parameter corresponds to an encryption algorithm, the first encryption algorithm and the second encryption algorithm are the same.

[0156] In step S202, according to the acquisition time of the environmental parameters, the encryption algorithm corresponding to the acquisition time of the environmental parameters is obtained as the second encryption algorithm. Different second encryption algorithms correspond to different times, or different acquisition times correspond to different second encryption algorithms. The acquisition time of the environmental parameters is the time when the environmental parameters are generated.

[0157] In some embodiments, the time of acquiring the environmental parameters refers to the time when the collection of the environmental parameters begins.

[0158] In some embodiments, the time of obtaining the environmental parameters refers to the time when the user completes inputting the environmental parameters.

[0159] In some embodiments, if there are multiple sensors collecting environmental parameters, the time of obtaining the environmental parameters may be the time when any sensor starts or ends collecting the environmental parameters.

[0160] In step S203, the first encryption algorithm and the second encryption algorithm are used as target encryption algorithms.

[0161] In some embodiments, the first encryption algorithm and the second encryption algorithm are combined as a target encryption algorithm, and the combination method of the first encryption algorithm and the second encryption algorithm is not limited herein.

[0162] In step S204, the environment parameters are encrypted according to the target encryption algorithm to obtain encrypted environment parameters. The encryption method of the environment parameters using the target encryption algorithm is not limited here.

[0163] In some embodiments, the environment parameter may be first encrypted using a first encryption algorithm to obtain a first encrypted parameter, and then the first encrypted parameter may be encrypted using a second encryption algorithm to obtain a second encrypted parameter, namely, the encrypted environment parameter.

[0164] In some embodiments, a preset target encryption algorithm matrix is ​​obtained. The target encryption algorithm matrix is ​​a matrix of three rows and three columns. The center matrix position of the target encryption algorithm matrix is ​​blank, and an encryption algorithm is added to each other matrix position. These encryption algorithms can be second encryption algorithms.

[0165] Obtain the acquisition time of the environmental parameters, take the center of the target encryption algorithm matrix as the clock center, and represent the time information of the acquisition time of the environmental parameters in the target encryption algorithm matrix in the form of a clock. The clock form includes an hour hand (the first target unit) and a minute hand (the second target unit). More pointers can be added to refer to different target time units.

[0166] In the target encryption algorithm matrix, the encryption closest to the direction of the hour hand is obtained as the first encryption algorithm, and the encryption algorithm closest to the direction of the minute hand is obtained as the second encryption algorithm.

[0167] The environmental parameter is encrypted based on the first encryption algorithm to obtain the first encryption parameter, and the first encryption parameter is encrypted based on the second encryption algorithm identifier to obtain the second encryption parameter, which is the encrypted environmental parameter.

[0168] In this way, the environmental parameters are more secure and less likely to be leaked.

[0169] See also Figure 5 , Figure 5The flowchart of the embodiment of the present application is shown in which a plurality of time units are preset, each value in each time unit corresponds to an encryption algorithm, a first encryption algorithm is preset, the first encryption algorithm and the second encryption algorithm are combined into an encryption algorithm as a target encryption algorithm, and the encryption algorithm corresponding to the acquisition time of the environmental parameter is obtained as the second encryption algorithm. The embodiment of the present application provides a plurality of time units are preset, each value in each time unit corresponds to an encryption algorithm, the first encryption algorithm is preset, the first encryption algorithm and the second encryption algorithm are combined into an encryption algorithm as a target encryption algorithm, and the encryption algorithm corresponding to the acquisition time of the environmental parameter is obtained as the second encryption algorithm Step S202 includes:

[0170] Step S301, randomly selecting at least one time unit from a plurality of preset time units as a target time unit;

[0171] Step S302, obtaining the value of the target time unit in the acquisition time of the environmental parameter;

[0172] Step S303: Use the encryption algorithm corresponding to the value of the target time unit as the second encryption algorithm.

[0173] The above three steps are described in detail below.

[0174] In step S301, the time unit refers to a time unit used in daily life, such as year, month, day, hour, minute, second, millisecond, etc. At least one time unit is selected from these time units as a target time unit.

[0175] In step S302, the value of the target time unit in the acquisition time of the environmental parameter is obtained. For example, if the target time unit is hours and minutes, and the acquisition time of the environmental parameter is 15:26 on September 8, the values ​​of the target unit are 15 and 26.

[0176] In step S303, each value of each time unit corresponds to an encryption algorithm and is not limited to the target time unit. This is because the target time unit may be changed by the user at any time, or automatically changed randomly to increase the randomness of the encryption algorithm and increase the confidentiality of environmental parameters.

[0177] The encryption algorithm corresponding to the value of the target time unit is used as the second encryption algorithm.

[0178] In some embodiments, there may be multiple second encryption algorithms, which may be combined with the first encryption algorithm respectively to obtain multiple target encryption algorithms, and the environmental parameters may be encrypted multiple times.

[0179] See also Figure 6 , Figure 6A flowchart of encrypting environmental parameters according to an embodiment of the present application. The present application embodiment provides a step S204 of encrypting environmental parameters, including:

[0180] Step S401, if there are multiple target time units, determine the priority of each second encryption algorithm according to the size order of the target time units, and the priority of the second encryption algorithm is positively correlated with the size order of the target time units;

[0181] Step S402: according to the priority of each second encryption algorithm, different second encryption algorithms are used in combination with the first encryption algorithm to encrypt the environmental parameters.

[0182] The above two steps are described in detail below.

[0183] In step S401, if there are multiple target time units, the priority of each second encryption algorithm is determined according to the size order of the target time units, and the priority of the second encryption algorithm is positively correlated with the size order of the target time units, such as when the priority is greater than that of the target time units. Of course, this priority can be freely set by the user.

[0184] In step S402, different second encryption algorithms are used in sequence in combination with the first encryption algorithm according to the priority of each second encryption algorithm to encrypt the environmental parameters multiple times, thereby further ensuring the confidentiality of the environmental parameters.

[0185] In some embodiments, the encryption algorithm obtained based on the target time unit can also be used as the target encryption algorithm. For example, if there are two target time units, the encryption algorithm corresponding to the first target time unit is an encryption algorithm lacking a core code. The encryption algorithm corresponding to the second target time unit is a core code adapted to the encryption algorithm corresponding to the first target time unit. The first encryption algorithm and the second encryption algorithm are used separately and combined as the target encryption algorithm.

[0186] In some embodiments, the first encryption algorithm is an encryption algorithm that lacks at least a portion of the core code. The number of target time units is the same as the number of "parts" missing from the first encryption algorithm, and the second encryption algorithm is obtained according to the target time unit, and all the second encryption algorithms are combined with the first encryption algorithm to obtain the target encryption algorithm.

[0187] In some embodiments, the first encryption algorithm is an algorithm with a few core codes, and the second encryption algorithm is a core code that can be combined with the first encryption algorithm. There are multiple target time units, and multiple second encryption algorithms are obtained according to the target time units, which are respectively combined with the first encryption algorithm to obtain multiple target encryption algorithms, and the environmental parameters are encrypted in turn.

[0188] See also Figure 7 , Figure 7 A flowchart of decrypting encrypted environmental parameters before obtaining control parameters corresponding to environmental parameters according to an embodiment of the present application is shown. The embodiment of the present application provides a step of decrypting encrypted environmental parameters before obtaining control parameters corresponding to environmental parameters according to environmental parameters, including:

[0189] Step S501, determining the time for obtaining the environment parameters according to the obtained encryption environment parameters;

[0190] Step S502, determining a target encryption algorithm for the environmental parameters according to the acquisition time of the environmental parameters;

[0191] Step S503, according to the target encryption algorithm, obtain the corresponding target decryption algorithm;

[0192] Step S504, decrypt the encrypted environment parameters according to the target decryption algorithm to obtain the environment parameters.

[0193] The above four steps are described in detail below.

[0194] In step S501, the acquisition time of the environment parameters is determined according to the obtained encrypted environment parameters. When the encrypted environment parameters are transmitted, the acquisition time of the environment parameters is carried.

[0195] In step S502, the target encryption algorithm of the environmental parameters is determined according to the acquisition time of the environmental parameters. The target encryption algorithm is determined according to the acquisition time of the environmental parameters based on the same mechanism as the encryption algorithm.

[0196] In step S503, a decryption algorithm corresponding to the target encryption algorithm is determined from the multiple decryption algorithms stored in the database.

[0197] In step S504, the encrypted environmental parameters are decrypted using a corresponding decryption algorithm to obtain environmental parameters, so as to adjust the parameters of the first environmental analysis model to obtain second environmental parameters, or to obtain the first response strategy and the second response strategy according to the environmental parameters.

[0198] Through this encrypted transmission mechanism, the above technical solution not only improves the security of data transmission, but also increases the security and anti-attack capability of the system by dynamically selecting the encryption algorithm. This method is particularly suitable for industrial environments with extremely high security requirements, and can effectively prevent data from being unauthorized access or tampering during transmission.
