Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs.

The embodiment of the application provides an industrial control rule merging method, which is specifically shown in fig. 1, and comprises the following steps:

101. And acquiring rule parameter elements in each industrial control rule to be combined.

Wherein the industrial control rule comprises at least one rule parameter element.

In the embodiment of the present invention, the rule parameter elements of the industrial control rule may be understood as certain specific parameter elements in the industrial control rule, for example, in a conventional industrial control rule, including an execution behavior related to the industrial control rule itself, a triggering condition of how to trigger the execution behavior, or a rule parameter required for triggering. In the embodiment of the invention, the rule parameter element can be any one or more of an identifier of a triggering condition triggering a certain operation behavior, a content of the triggering condition, or a specific certain parameter, a certain type of parameter and an identifier of the parameter corresponding to the triggering of the certain operation behavior. Here, the specific selection of the rule parameter element may be selected based on the actual needs of the user.

Specifically, in order to facilitate the description of this embodiment and the following embodiments, the rule parameter element is described in terms of the content of the parameters required when the industrial control rule is triggered, that is, the rule parameters described above. In practical application, an industrial control rule can be simply regarded as two parts, wherein one part is a rule parameter for triggering the industrial control rule, and the other part is an operation behavior required to be executed after the rule is triggered. Therefore, in the process of merging industrial control rules, the merged industrial control rules generally have the same operation behavior, but different rule parameters. In this process, rule parameters are also classified into different categories, i.e., parameter classifications, and a particular such parameter classification may include: address class, function code class, numeric class, string class, numeric range class, etc.

102. And determining the rule type corresponding to each industrial control rule based on the rule parameter elements.

Based on the description of the foregoing steps, since different industrial control rules actually need to be divided into different classifications for merging when merging is performed subsequently under the condition that rule parameter elements are different, it is actually necessary to determine what rule type each industrial control rule actually corresponds to after the rule parameter elements are determined in the foregoing steps.

In this embodiment, the rule type determining process may be specifically performed in a manner of adding different labels to different rule parameter elements, and, of course, since the number of rule parameter elements included in an industrial control rule may be multiple different in practical application, there may be a case that one industrial control rule is determined to be multiple different rule types in the rule type determining process, or when a certain rule parameter element exists, all industrial control rules including the rule parameter element may be divided into one rule type, and industrial control rules of other rule parameter elements are divided into another rule type. The rule type, the number and the type of the rule types, which are determined for each specific industrial control rule are not limited herein, and may be selected based on the needs of the user. Specifically, as can be seen from the foregoing description of the steps, when the rule parameter element is exemplified by the rule parameter, in this step, the rule parameters in different industrial control rules can be actually used as the basis for classifying the industrial control rules, so as to determine the rule type of each industrial control rule. Of course, the industrial control rule may be classified in other manners to obtain different rule types, where, for example, the classification may be performed according to the number of rule parameters included in the industrial control rule, only one rule parameter is classified into one type, and the classification including a plurality of rule parameters is classified into another type. Here, any of the above manners may be adopted to divide the industrial control rule into different rule types, and the method is not limited herein, and may be selected according to actual needs of a user.

103. And executing merging operation on the corresponding industrial control rule based on the rule type.

After determining the rule type of each industrial control rule, the merging operation can be performed on the industrial control rule corresponding to the rule type, and because the merging operation is not necessarily performed on the basis of classifying the industrial control rules, the type merging is performed on the basis of the rule, and then in the practical application process of the method, a user can select one or more rule types from a plurality of different rule types to perform the merging operation based on own needs, so that the process of performing the merging operation can be determined to be more flexible and the industrial control rules can be merged with pertinence.

The application provides an industrial control rule merging method, in the embodiment of the application, rule parameter elements in each industrial control rule to be merged are firstly obtained, wherein the industrial control rule comprises at least one rule parameter element; then, determining a rule type corresponding to each industrial control rule based on the rule parameter elements; and finally, based on the rule type, executing the merging operation on the corresponding industrial control rule, thereby realizing the merging function of the industrial control rule. Compared with the prior art, the method and the device can classify the industrial control rules based on rule parameter elements in the industrial control rules to obtain rule types corresponding to each industrial control rule, and then combine the corresponding industrial control rules based on the rule types, so that the effect of combining the industrial control rules in the process of recording and collecting the industrial control rules can be realized, the data of the industrial control rules stored in the industrial control equipment can be reduced after the combination, the problem that more industrial control rules are difficult to store under the condition of limited storage space is avoided, and the problem that the combination is performed according to the rule types after the rule types are determined based on the rule parameter elements in the combination process, namely, the corresponding types can be selected according to different requirements for different rule types, the number of the industrial control rules is effectively reduced in the combination process, and the combination process has better controllability.

For more detailed description, the embodiment of the present application provides another method for merging industrial control rules, specifically as shown in fig. 2, the method includes:

201. and acquiring rule parameter elements in each industrial control rule to be combined.

Wherein the industrial control rule comprises at least one rule parameter element.

In the embodiment of the present application, as shown in the foregoing description of the embodiment, since the rule parameter element in the industrial control rule may be a rule trigger condition or a rule trigger parameter, that is, a rule parameter, the industrial control rule to be combined generally has the same operation behavior in the process of combining the industrial control rules, but the rule parameter elements are different rules. In this embodiment, when the industrial control rules are to be combined, rule parameter elements in each industrial control rule need to be determined first and acquired.

202. And determining the rule type corresponding to each industrial control rule based on the rule parameter elements.

Each rule parameter element comprises at least one rule parameter, and each rule parameter has a corresponding parameter classification, wherein the rule parameter is used for triggering the industrial control rule.

The step when determining the rule type of the industrial control rule based on the rule parameter element can be specifically: and determining the rule type corresponding to each industrial control rule based on the parameter classification corresponding to each rule parameter included by the rule parameter element.

Since rule parameter elements are different for different industrial control rules, in this embodiment, for convenience of description, the rule parameter elements are described herein in a manner of being specific to rule parameters. Based on this, in this embodiment, the industrial control rule may be regarded as two parts, wherein one part is a rule parameter for triggering the industrial control rule, and the other part is an operation behavior that needs to be executed after the rule is triggered. Meanwhile, as can be seen from the description of the foregoing steps, in this embodiment, the rule parameter element takes the rule parameter as an example, and in this step, the industrial control rules are divided based on the rule parameter, that is, the rule type corresponding to each industrial control rule is determined. In this process, rule parameters are also classified into different categories, i.e., parameter classifications, and a particular such parameter classification may include: address class, function code class, value class, string class, and value range class. Thus, the first and second substrates are bonded together,

In the process of determining the rule type in this embodiment, the determination may be understood as being performed based on the parameter classification to which the rule parameter included in the industrial control rule belongs, and specifically may be understood as adding a corresponding label to the rule parameter classification, that is, there may be a case that one industrial control rule corresponds to a plurality of different labels in this process. For example, when an industrial control rule includes a plurality of different rule parameters, and the parameter classifications to which each rule parameter belongs are different, then according to the method of this step, the industrial control rule is added with labels corresponding to the different parameter classifications, that is, the industrial control rule is marked with a plurality of labels, and then in the process of determining the rule type of the industrial control rule, the process can be divided into two different modes: one of the two ways is to determine that the labels all comprise a certain parameter classification are a certain rule classification, and the other way is to divide a plurality of industrial control rules with the same label combination into one rule classification after the corresponding labels are respectively added to different parameter classifications.

203. And executing merging operation on the corresponding industrial control rule based on the rule type.

Specifically, in practical application, even if the merging operation is performed during the merging of the industrial control rules, the merging operation does not mean that all the industrial control rules need to be merged, wherein the control requirement of the user on the number of the industrial control rules can be met by only partially merging, in this case, when the merging process is performed on each type of corresponding industrial control rule based on the rule type, the corresponding priority can be actually set for different rule types, so that the merging can be performed step by step according to the priority, and the merging can be performed according to the priority order on the basis of meeting the classification merging, thereby avoiding the pressure of system resources caused by the merging of the industrial control rules with low priority.

Therefore, in this embodiment, each rule type corresponds to N priorities, where N is a positive integer.

Based on this, this step, when executed, may include:

step A, determining N priorities corresponding to the rule types respectively;

step B, determining N batches of rules to be combined based on the determined N priorities, wherein the priorities of industrial control rules in the rules to be combined in the same batch are the same;

And C, executing merging operation on the rules to be merged of the N batches according to the N priority orders.

Since the difference of the parameter classification affects the specific merging mode of the subsequent merging process and also affects the priority order in merging, N may be 3 in this embodiment for convenience of description, that is, in this case, the priority in merging is set to three levels, including the first level, the second level and the third level; the priorities of the first stage, the second stage and the third stage at the time of merging are sequentially decreased.

Specifically, in this step, as known from the foregoing examples, since rule parameters can be specifically classified into address classes, function code classes, numeric classes, character strings, and numeric range classes, and rule types are determined based on parameter classification of rule parameters, that is, in the process of determining priorities based on rule types, it is actually possible to mark based on specific kinds of rule parameters, where in the case of priorities of three-level classification, determining N priorities corresponding to the rule types, respectively, may include when executing:

when the parameters are classified into the address class, determining the priority of the corresponding merging as the first level, the second level and the third level;

When the parameters are classified into the function code class, determining the priority of merging corresponding to the parameter classification as the first stage;

when the parameter is classified into the numerical class, determining priorities at the time of merging corresponding to the parameter classification as the first stage, the second stage and the third stage;

when the parameters are classified into the character string class, determining the priority of merging corresponding to the parameter classification as the third level;

and when the parameters are classified into the numerical range class, determining the priority of merging corresponding to the parameter classification as the second level and the third level.

Specifically, the above multiple parameter classifications and the priority of the specific combination may be determined as shown in table 1:

TABLE 1

After the priorities of the different rule parameters corresponding to the classification are set, the priorities of the industrial control rule corresponding to the combination are determined. It can be known from the foregoing description that, since each parameter classification corresponds to at least one priority in merging, and the number of parameter classifications included in each industrial control rule is different, the priority in merging matched by each industrial control rule may be multiple. For example, when the parameter classification corresponding to the rule parameter included in the industrial control rule a is only an address class, the priority of the industrial control rule corresponding to the address class in combination is a first level, a second level and a third level, and the priority of the industrial control rule a in combination is the first level, the second level and the third level. When the industrial control rule B includes two rule parameters 1 and 2, and the two rule parameters correspond to the character string class and the function code class respectively, then the priorities of the two parameter classifications during the corresponding merging are the third level and the first level respectively, and the priorities of the industrial control rule B during the merging are the first level and the third level respectively.

Further, in step C of the present step, the merging operation is performed on the rules to be merged of the N batches, and the performing may specifically be: and executing the merging operation on the rules to be merged belonging to the same rule type in the rules to be merged of each of the N batches.

After the priority of the industrial control rules is determined by rule classification during the merging, the industrial control rules can be merged by corresponding batches according to the priority thereof based on the method of the step, that is, in this case, the industrial control rules can be merged step by step according to the marked priority of the step.

Specifically, in this step, based on the rule type, performing the merging operation on the corresponding industrial control rule includes:

mode a: in the industrial control rules, acquiring industrial control rules with the same parameter classification, and recording the industrial control rules as first rules; and executing the merging operation on the rule parameters in the plurality of first rules according to the rule type.

Further, since each parameter class corresponding to each industrial control rule to be combined has at least one rule parameter, the process of combining the industrial control rules based on rule types further includes:

Mode B: among the industrial control rules to be combined, determining the industrial control rule with the target priority as a second rule; determining a set formed by rule parameters contained in each second rule as a first parameter set; determining all parameter classifications corresponding to the second rule, and determining a set formed by rule parameters under each parameter classification as a second parameter set to obtain a plurality of second parameter sets corresponding to all parameter classifications; calculating the plurality of second parameter sets by using a Cartesian product algorithm to obtain a third parameter set, wherein elements in the third parameter set are combination sequences of rule parameters in each second parameter set; when the third parameter set matches the first parameter set, determining that the second rule meets a merging condition, and/or executing merging on the second rule.

Further, in the implementation of the method B, there is a case that the third parameter set and the first parameter set do not match, then the third parameter set and the first parameter set may be redetermined and re-matched by narrowing the scope of the second rule, based on this, the step further includes, after the step B:

Mode C: when the third parameter set is not matched with the first parameter set, part of the industrial control rules in all the second rules are redetermined as the second rules, and the first parameter set and the third parameter set are redetermined respectively; when the redetermined first parameter set matches the redetermined third parameter set, determining that the redetermined second rule meets the merging condition, and/or performing merging on the redetermined second rule.

In the implementation process of the above-mentioned three modes of merging operation in mode a, mode B and mode C, it is actually determined which rules can be specifically merged, that is, the above-mentioned three modes belong to all industrial control rules, which can be merged for the industrial control rules classified by the same rule.

For the merging operation in the mode a, all rule parameters in all the plurality of industrial control rules including only the parameter classification need to be regarded as a whole, and the rule parameters are completely consistent to perform the merging operation. That is, only the industrial control rules including the parameter classifications with the same priority (in the case that the priority set in the embodiment is three-level, it may be assumed that the two are the first-level) are processed in the process of the merging operation, where the industrial control rules including the same parameter classification are merged in the merging process, that is, only the parameter classifications with the same priority are related to the two industrial control rules, and if the parameter classifications of the two parameter classifications are different, the two parameter classifications are not merged in the process of the first merging operation. For the merging operation in the mode B and the merging operation in the mode C, it may be understood that a determining process of determining which industrial control rules can be merged into one industrial control rule in a plurality of industrial control rules according to a preset algorithm and parameter classification of rule parameters, where the preset algorithm may be a cartesian product algorithm, and the algorithm is mainly used to combine elements in a plurality of sets, so as to obtain element combinations, where a meaning represented by the element combinations is a composition manner between elements in different sets, and all combinations of elements between the plurality of sets may be represented.

Specifically, for the implementation of mode a:

for example, when the rule parameter included in the industrial control rule a is 172.24.2, the rule parameter included in the industrial control rule B is read, and based on the foregoing description, the parameter corresponding to the rule parameter 172.24.2 of the industrial control rule a is classified into an address class, and the priority corresponding to the industrial control rule is a first stage, a second stage and a third stage; the parameters corresponding to the rule parameters read of the industrial control rule B are classified into function code classes, the priority corresponding to the industrial control rule B is a first level, and the merging levels of the two are all the first level, so that when merging, whether the parameter classifications of the two are consistent is determined, and the address class and the function code class are not identical, so that the rule of the first merging operation is not satisfied. When the rule parameters of the industrial control rule C are 172.24.3, the parameter classification of the rule parameters of the pre-industrial control rule A belongs to the address class, so that the condition of the mode A merging operation is met, and the industrial control rule A and the industrial control rule C can be executed to be merged in the mode A merging operation process, so that the industrial control rule is obtained after merging.

Further, taking the above example as an example, among the plurality of industrial control rules, the industrial control rule a, the industrial control rule B and the industrial control rule C all refer to the rule parameters of the first stage, but when the method described in this embodiment is executed, not all the industrial control rules meet the condition of the merging operation of the execution mode a, in this process, the industrial control rule classified by the identical parameters needs to be determined as the first rule, that is, the industrial control rule a and the industrial control rule C are determined as the first rule, that is, the two industrial control rules can execute the first merging operation, and then the two industrial control rules can execute the specific merging operation, where the merging mode is to execute the merging operation by classifying the rule parameters in the first rule according to the parameters, so in the case that the rule parameters of the industrial control rule a are 172.24.2 and the rule parameters of the industrial control rule C are 172.24.3, the rule parameters in the merged industrial control rule X are 172.24.2 and 172.24.3.

Further, for the mode B, the implementation can be understood as follows:

in the process of executing the merging operation of the mode B, all the industrial control rules related to the same priority (which can be assumed to be all industrial control rules including rule parameters corresponding to the second level) are merged, in this process, the coverage range of the rule parameters in the second rule is determined, and whether the coverage range of a combination sequence of the cartesian product algorithm is consistent with the rule parameters according to the parameter classification is determined, that is, whether the first parameter set is matched with the third parameter set, wherein the elements included in the first parameter set are all rule parameters extracted from the second rule, and if the two rule parameters are consistent, it is indicated that all the combination cases of the rule parameters combined according to the parameter classification are consistent with all the combination cases of the rule parameters included in the industrial control rules, then the second rules can be merged, and thus the merging operation of the mode B is executed.

For example, when four rules in the second rule are determined to be rule 1 to rule 4 respectively, the range obtained by extracting the rule parameters according to the parameter classification mode, that is, the first parameter set is shown in table 2:

Industrial control rule	Parameter Classification A	Parameters respectively B
			Rule 1	a	1
Rule 2	a	2
			Rule 3	b	1
Rule 4	b	2

TABLE 2

Wherein the elements included in the first parameter set are actually { a,1} { a,2} { b,1} { b,2}, and the combined sequence of rule parameters of the 4 rules can be determined by using a Cartesian product algorithm as follows:{a,b}*{1,2}。

due to the third parameter set calculated by the Cartesian integration method{a, b = { (1, 2) = { { (a, 1) { (a, 2) { (b, 1) { (b, 2) } is consistent with the first parameter set "{ a,1} { (a, 2) { (b, 1) } { (b, 2) }". Then based on analysis, it is known that the coverage of the first parameter set is equal to the third parameter set formed by the combination sequence calculated by the cartesian integration algorithm, and in this case, the rules 1 to 4 can be combined into one rule X as shown in table 3:

industrial control rule	Parameter Classification A	Parameters respectively B
			Rule X	[a,b]	[1,2]

TABLE 3 Table 3

Specifically, for the executing process of the mode C, the redefining a part of the industrial control rules in all the second rules as the second rules, and redefining the first parameter set and the third parameter set respectively may specifically be:

screening out part of industrial control rules from all the second rules by using a preset loop body algorithm to serve as the redetermined second rules; and the preset loop body algorithm is used for reducing the rule number of the second rule when the first parameter set is not matched with the third parameter set, and redefining the second rule with the reduced rule number as the second rule until the redetermined first parameter set is matched with the redetermined third parameter set or the number of the industrial control rules is reduced to a preset value.

Based on this, for mode C, its merging process may be:

in the merging operation of the mode C, the method is the same as that of the mode B, and it is determined by using a cartesian product algorithm whether the coverage formed by the combination sequence formed by the rule parameters is consistent with the coverage formed by the rule parameters in practice of all the second rules, if not, the number of the industrial control rules participating in the calculation of the combination sequence by using the cartesian product algorithm is decreased, that is, the number of the industrial control rules is decreased, and then the first parameter set and the third parameter set of the second rules are re-determined as the second rules, and then, whether the first parameter set and the third parameter set of the second rules are matched or not is checked until the industrial control rules corresponding to a certain rule parameters are consistent between the combination sequence (that is, the third parameter set) and the range formed by the rule parameters directly extracted from the second rules (that is, the first parameter set) after the cartesian product algorithm is performed, which indicates that the rule parameters in the second rules are identical with the actual rule parameter combination in the second rules according to the combination condition of the rule parameters calculated by the cartesian product algorithm, and then the redetermined second rules can be merged.

For example, when it is determined that the second rule is rule 1 to rule 5, respectively, the parameter set calculated according to the method of the present step according to each rule parameter in the second rule is as shown in table 4:

Industrial control rule	Parameter Classification A	Parameters respectively B
			Rule 1	a	1
Rule 2	a	2
			Rule 3	b	1
Rule 4	b	2
			Rule 5	c	1

TABLE 4 Table 4

Wherein the first parameter set at this time is "{ a,1} { a,2} { b,1} { b,2} { c,1}" then the method based on this step starts to calculate the assigned rule parameters involved in the merging in the second rule based on the preset loop body, wherein the cartesian product sequence determined by all rule parameters, that is, the third parameter set is { a, b, c } {1,2 = { a,1} { a,2} { b,1} { b,2} { c,1} { c,2}, and then the combined sequence obtained by the cartesian algorithm is found to be inconsistent with the first parameter set "{ a,1} { a,2} { b,1} { c,1}" related to the above table 4 (when the third parameter set is more than { c,2} rule parameters are combined), one of the two are not matched, that is one of the cartesian product rules can be reduced, that is the rule parameters are reduced when the rule set is determined by the second rule set according to the algorithm is calculated according to the algorithm, that the second rule set is calculated according to the step 5:

industrial control rule	Parameter Classification A	Parameters respectively B
			Rule 1	a	1
Rule 2	a	2
			Rule 3	b	1
Rule 4	b	2

TABLE 5

The cartesian product algorithm yields a combined sequence (i.e. a redetermined third set of parameters) of: { a, b } {1,2 = { { a,1} { a,2} { b,1} { b,2} }, when the comparison finds that the third parameter set at this time is consistent with both the redetermined first parameter set, then the redetermined second rule, namely rule 1 to rule 4, can be combined next.

Further, in the process of merging operation, when merging specific rule parameters, different rule parameters in different parameter classifications are executed differently, based on this, the step executes the merging operation on the corresponding industrial control rule based on the rule type, and when the specific rule parameters are executed, the steps can be divided into the following cases:

for the address class, a specific merging operation can respectively extract the address of the rule parameters of each industrial control rule to obtain a plurality of address information, and merge the plurality of address information to obtain merged address information; the combined address information comprises an address range formed by a plurality of address information and/or an address set formed by a plurality of address scattered points.

As shown in fig. 2-a, where arg1 and arg2 are two parameter classifications respectively, rule parameters of the two parameter classifications in the plurality of industrial control rules in the figure are the same, so that the two parameter classifications can be directly de-overlapped and belong to address classes, and in the process of merging the industrial control rules, if continuous addresses exist among rule parameters 172.24.2.1, 172.24.2.2, 172.24.2.3 and 172.24.2.4, then the addresses need to form an address range if continuous, and rule parameters 172.24.3.3 and 172.2.2.31 are discontinuous addresses and form an address set formed by address scattering points, then the rule parameters of the finally obtained merged industrial control rule are: [ [172.24.2.1-172.24.2.4], [172.24.3.3], [172.2.2.31], [ [1234] ] and [ (1256 ] ].

For the corresponding function code class, the merging operation may respectively perform function code extraction on the parameters of each industrial control rule to obtain a plurality of function codes, and de-duplicate the plurality of function codes to obtain a merged function code. Specifically, as shown in fig. 2-B, the rule parameters in the 5 rules are read, read, write, write and write, respectively, so that the first two rules can be combined into a combining rule with read as the rule parameter, and the last three industrial control rules are combined into a combining rule with write as the rule parameter.

When the parameters are classified into the numerical value classes, the merging operation can respectively extract the numerical values at the rule parameters of each industrial control rule to obtain a plurality of numerical values, and merge the numerical values to obtain a merged numerical value, wherein the merged numerical value comprises a numerical value range formed by the numerical values and/or a numerical value set formed by the numerical value scattered points.

For example, as shown in fig. 2-C, there is an intersection between rule parameters [1234-1236] and rule parameters [1234-1237], so that rule parameters are extracted and combined to form rule parameters [1234-1237], and the remaining rule parameters with repetition are de-duplicated, and finally the rule parameters of the combined industrial control rule are obtained as follows: [1234-1237][9][234][2234-2334].

And for the parameters classified into the numerical range classes, the numerical range extraction can be respectively carried out on the rule parameters of each industrial control rule when the merging operation is carried out, so as to obtain a plurality of numerical ranges, and the union of the numerical ranges is calculated, so that the numerical ranges after merging are obtained.

Specifically, when the rule parameters of the class of the numerical ranges are combined, the combination may be performed in a set-combining manner, that is, the numerical ranges after the combination are obtained by taking the union set are actually performed in a set-taking-union manner. For example, when a {1,100} n B {10,20} = B {10,20}, say that a contains B, then during the merge operation, the rule parameter after the merge is { a }; when a {1,100} n B {50,110} = C{50,100}, say A B there is intersection, then the rule parameter after the merging operation is performed in this step is { A }; when (when)The two sets of instructions A B do not intersect, then the rule parameters after this step performs the merge operation are { A, B }.

And when the parameters are classified into the character string classes and the rule parameters are multiple, extracting the character string from the rule parameters of each industrial control rule to obtain multiple character strings, determining the same part and different parts in the multiple character strings, calculating the union of the different parts, and determining the character strings formed by the union of the same part and the different parts as the combined character strings.

Wherein prior to said determining the same portion and different portions of the plurality of character strings, the method further comprises:

when the rule type is a character string, determining the similarity between any two character strings in a plurality of character strings based on a preset similarity algorithm, wherein the similarity is equal to the ratio between the number of the same characters in the two character strings and the number of all characters after the duplicate of the two character strings is removed;

if the similarity reaches a preset similarity threshold, determining the same part and different parts in the corresponding two character strings until the same part and different parts in the plurality of character strings are obtained

Specifically, when the industrial control rule of the rule parameters of the character string class is merged, the jaccard similarity calculation may be performed on any two of the plurality of character strings, where the jaccard similarity calculation is an algorithm for determining the similarity degree between two sets, and a specific calculation process may be: the number of characters in the intersection of the two sets divided by the total number of characters in the duplicate of the union of the two sets is removed. That is, it is determined whether or not a merging operation can be performed according to the degree of similarity between characters between character strings. Specifically, the similarity threshold may be set by the user, and the merging operation is performed when the similarity threshold is higher than the threshold. For example, taking fig. 2-D as an example, when the parameter classifications arg2 of the five industrial control rules are qq1.Txt, qqq0.Txt, qqq2.Txt, qqq3.Txt, and qqq4.Txt, respectively, and the values obtained by jaccard similarity calculation exceed the similarity threshold, which indicates that the similarity of these rule parameters is extremely high, the similar parts qqq _, txt, and the different parts [0-4] in the character string are extracted according to the method of this step, and then the rule parameters of the final combined industrial control rule are qqq [0-4] txt.

204. And determining whether the number of the industrial control rules accords with a preset termination condition.

Wherein, the preset termination condition includes: the number of the industrial control rules is lower than a preset number, or the ratio of the number of the industrial control rules to the number of the initial industrial control rules is lower than a preset ratio.

Specifically, in the judging process, the method may specifically be: and judging that the number of the stored industrial control rules is lower than a preset number.

Since the purpose of the method for merging industrial control rules in this embodiment is to indicate that the number of remaining industrial control rules meets the user's expectations when the number of the industrial control rules stored in the industrial control device is lower than a certain limit value, that is, after merging the industrial control rules to reduce the number of the stored industrial control rules, the industrial control rules are in compliance with the preset suspension conditions. Similarly, in some cases, it may also be performed if the ratio of the combined number to the initial industrial control rule number is lower than a preset ratio, for example, the preset suspension condition is set to be one fifth of the original number, if the combined number is one sixth of the original number, the combined number is obviously higher than the expected value of the user, and then the preset suspension condition is met.

Based on the judgment result, when it is determined that the number of the industrial control rules does not meet the preset termination condition, step 205 is executed; otherwise, step 206 is performed.

205. And if the number of the industrial control rules is determined to be not in accordance with the preset termination condition, executing the merging operation.

In this case, it is actually explained that the number of industrial control rules is large, and the merging operation is required, and then the process returns to the step 203.

The specific judging process can be based on the steps that the industrial control rule is compressed to a first threshold value and then judging whether the number of the industrial control rules reaches a second threshold value, wherein the second threshold value is lower than the first threshold value.

When it is determined that the number of currently stored industrial control rules has reached the first threshold, the industrial control rules need to be merged according to a preset merging strategy, and the number of the industrial control rules is generally reduced to be below a second threshold smaller than the first threshold, so that a specific merging process in the process can be actually performed step by step based on the priority of merging which has been determined previously.

206. And if the number of the industrial control rules accords with the preset termination condition, terminating the execution of the merging operation.

When the number of the industrial control rules is determined to be smaller than a certain threshold value or the number of the industrial control rules after combination reaches a preset proportion before combination, the number of the industrial control rules is smaller at the moment, further combination is not needed, that is, the number of the current industrial control rules accords with a preset suspension condition, and then combination operation is not needed.

In addition, it should be noted that, in the present steps 204-206, the process of determining and determining whether to perform the merging operation or to terminate the merging operation based on the number of the industrial control rules may be performed after the foregoing merging operation is performed, or may be performed after each merging operation when a plurality of merging operations are performed, so as to ensure that in practical applications, whether to further perform the subsequent merging operation is determined based on the number of the current industrial control rules after each merging operation is performed, thereby making the merging process more controllable.

In addition, after the merging operations of the modes a to C are performed, there may be a case where the number of the merged rules does not meet the suspension condition, and then the operation of forced merging, that is, forcing the plurality of rules to be merged into one rule, is further required to be performed, and in this embodiment, the method further includes:

When the number of the industrial control rules after the preset times of merging operation is determined to still not meet the preset termination condition, in the industrial control rules after the preset times of merging operation, rule parameters under the same parameter classification are subjected to merging operation, and the same rule parameters in the rule parameters after the merging operation are subjected to de-duplication to obtain a fourth parameter set;

and determining the fourth parameter set as a merged rule parameter.

When the method described in this embodiment is executed, since there may be a situation that the number of the industrial control rules is still high after the merging operation in three ways, or the proportion of the merging industrial control rules is too small, in this case, forced merging needs to be performed according to the method described above, for example, as shown in fig. 2-E, among the five industrial control rules, the former two industrial control rules are exemplified, in rule 1 and rule 2, rule parameters of the two rules are respectively subjected to merging operation according to parameter classification, and in this case, it is found that a repeated rule parameter a appears in parameter classification arg1, then the repeated rule parameter needs to be subjected to de-duplication, and in other two parameter classifications arg2 and arg3, rule parameters under these two parameter classifications need to be taken and merged, and in the same way, the subsequent rules are also performed in the same way and finally obtain rule parameters of the fourth parameter set, which is determined as the rule parameter set after merging, shown in the right side in fig. 2-E.
