Description

Technical Field

[0001] The present application relates to the field of industrial safety control, and specifically to safety control methods, devices, electronic equipment, and storage media for industrial operations. Background Art

[0002] With the continuous development of Internet technology and industrial control, safety control technology is increasingly being used in industrial production. In existing technologies, the focus is on learning whether a single instruction is compliant and issuing an alarm when an instruction is not compliant.

It may receive multiple instructions, such as heating to a certain temperature, feeding a certain gas, and pressurizing to a certain Pa.

For example, assuming that after injecting gas a, gas b cannot be injected. Based on the judgment of a single instruction, each instruction is compliant, and it is impossible to reasonably analyze and control it. Summary of the Invention

Electronic device 200 can be a host computer, tablet computer, etc., and is used to implement the industrial operation safety control method.

[0049] In one embodiment, the memory 202 can be implemented by any type of volatile or non-volatile memory device or a combination thereof, including but not limited to random access memory (RAM), read only memory (ROM), static random access memory (SRAM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), and electrically erasable programmable read-only memory (EEPROM).

The instructions are executed by the processor 203 so that the electronic device 200 can execute the entire process or part of the process of the method in the following embodiment to achieve safe control of industrial operations.

[0052] Please refer to Figure 3 , which is a flow chart of a safety control method for industrial operations provided by an embodiment of the present application, which can be Figure 2 The method executed by the electronic device 200 shown includes S310 - S330 .

[0053] S310: Cache the industrial operation instructions received in chronological order to obtain industrial control business sequences of different dimensions.

[0054] In industrial production, the second terminal receives industrial operation instructions for industrial equipment issued by the first terminal. In this step, these industrial operation instructions are stored in chronological order, and the chronological order of storage is used to form an industrial control business sequence. According to the preset sequence analysis dimension, assuming the preset sequence analysis dimension is 5, the industrial control business sequence can have 1 dimension, 2 dimensions, 3 dimensions, 4 dimensions, and 5 dimensions, providing five different dimensional industrial control business sequences. Among them, 1 dimension indicates that the industrial control business sequence contains one industrial operation instruction. 2 dimensions indicate that the industrial control business sequence contains two consecutive industrial operation instructions, and so on.

[0055] In one embodiment, according to the address information of each work operation instruction, the work operation instructions with the same address information may be arranged in order of receipt to obtain industrial control service sequences of different dimensions corresponding to the address information.

[0056] Address information includes the source address and destination address. An industrial operation instruction includes the source address, destination address, and operation content. The source address is the address of the terminal issuing the operation instruction, the destination address is the address of the device that ultimately executes the operation, and the operation content is the specific operation that the device needs to perform.

[0057] When arranging the work operation instructions, the work operation instructions containing the same address information are arranged and cached in chronological order to obtain industrial control business sequences of different dimensions with the same address information.

[0058] In one embodiment, in response to a start instruction of a specified sequence mode, the second terminal may extract target operation instructions from the received industrial operation instructions in sequence according to the specified sequence mode to obtain industrial control business sequences of different dimensions.

[0059] The specified sequence mode may include any one of an operation serialization mode, a parameter serialization mode, and an operation parameter combination serialization mode.

[0060] Each mode includes a source address, a destination address, and an operation. The operation content of the operation sequence mode includes different operations on the device, the operation content of the parameter sequence mode includes different parameter values ​​for the same operation, and the operation content of the operation parameter combination sequence mode includes different parameter values ​​for different operations.

[0061] For example, the operation serialization mode can be: source address, destination address, operation a; source address, destination address, operation b; source address, destination address, operation c...

[0062] The parameter serialization mode can be: source address, destination address, operation a, value x; source address, destination address, operation a, value y; source address, destination address, operation a, value z...

[0063] The operation parameter combination serialization mode can be: source address, destination address, (operation a, value x); source address, destination address, (operation b, value y); source address, destination address, (operation c, value z)...

[0064] When the user turns on the switch of a certain sequence mode, the second terminal receives the start instruction of the specified sequence mode, and the second terminal extracts all industrial operation instructions of a certain sequence mode specified by the user from all received industrial operation instructions to obtain industrial control business sequences of different dimensions.

[0065] S320: Based on known standard operation sequences of different dimensions, compare the industrial control service sequence of the same dimension with the standard operation sequence to determine whether the industrial control service sequence matches the standard operation sequence.

[0066] During the learning phase, an industrial control business sequence consisting of operating instructions that enable the normal operation of the equipment can be pre-stored in the database, which is called a standard operation sequence. The standard operation sequence can also have different dimensions. Assuming that the preset sequence analysis dimension is 5 dimensions, the standard operation sequence can have 1-dimensional, 2-dimensional, 3-dimensional, 4-dimensional and 5-dimensional standard operation sequences. After obtaining industrial control business sequences of different dimensions in S310, the one-dimensional industrial control business sequence can be compared with the pre-stored one-dimensional standard operation sequence to determine whether they match; the two-dimensional industrial control business sequence can be compared with the two-dimensional standard operation sequence to determine whether they match; the three-dimensional industrial control business sequence can be compared with the three-dimensional standard operation sequence to determine whether they match; and so on.

[0067] S330: If the industrial control service sequence of any dimension does not match the standard operation sequence, perform a security control operation.

[0068] The security control operation can include issuing an alarm or blocking the issuance of industrial operation instructions. In one embodiment, if the industrial control service sequence of a certain dimension does not match the standard operation sequence, the second terminal issues an alarm and blocks the issuance of the industrial operation instruction, thereby preventing the device from executing the operation instruction.

[0069] When it is found that the industrial control service sequence of each dimension matches the standard operation sequence, the second terminal can send the industrial control service sequence to the industrial equipment.

[0070] The industrial operation security control method provided in this embodiment sequentially caches industrial operation instructions with the same address, obtaining industrial control service sequences of different dimensions arranged in the order they were received. The system then compares these service sequences to see if they conform to standard service sequences of different dimensions. If they do not conform to the standards, an alarm is issued. This method verifies complex industrial operation flows, preventing the execution of complex, illegal, or non-compliant industrial operations and improving industrial production safety.

[0071] Please refer to Figure 4 , which is a flow chart of a safety control method for industrial operations provided by another embodiment of the present application, which can be Figure 2 The electronic device 200 shown executes the method including S410 - S450 .

[0072] S410: extracting industrial operation instructions under normal operating conditions according to a preset sequence analysis dimension, and arranging them in sequence to obtain a plurality of standard operation sequences of different dimensions.

[0073] The sequence analysis dimension refers to the maximum number of dimensions of the recorded and analyzed industrial control business sequences and standard operation sequences. Dimensionality refers to the number of industrial operation instructions contained in the industrial control business sequences and standard operation sequences. A standard operation sequence is an operation sequence that enables normal device operation. During the learning phase, traffic parsing is first performed. Instruction transmission is based on the HTTPS protocol, and the protocol rules are parsed to obtain the content of the operation instructions. Then, standard operation sequences that contain the specified number of operation instructions and enable normal device operation are stored. Assuming the sequence analysis dimension is 5, standard operation sequences can have 1, 2, 3, 4, or 5 dimensions.

[0074] The process of learning the industrial control flow sequence is as follows Figure 5 As shown. Learning is performed in the initial stage according to the learning dimension set by the user, for example, setting the sequence analysis dimension to N dimensions. First, a one-dimensional analysis is performed on each received industrial operation instruction (i.e., whether each industrial operation instruction exists in the database). If this one-dimensional sequence exists in the database, a two-dimensional analysis is performed (i.e., whether any two consecutive industrial operation instructions exist in the database). If not, this one-dimensional sequence is recorded and then a two-dimensional sequence is performed. If this two-dimensional sequence exists in the database, a three-dimensional analysis is performed. If this two-dimensional sequence does not exist in the database, a three-dimensional analysis is performed (i.e., whether any three consecutive industrial operation instructions exist in the database). Similarly, the N-dimensional sequence is analyzed. If this N-dimensional sequence exists, the N-dimensional sequence learning is completed. If it does not exist, a new N-dimensional sequence is recorded in the database and generated.

[0075] In one embodiment, a plurality of standard operation sequences of different dimensions are stored in a database, and the extraction of the standard operation sequence is stopped until a stopping condition is satisfied.

[0076] In one embodiment, the stopping condition includes any one of the following three stopping conditions: the number of repetitions of each standard operation sequence exceeds a first threshold, the time without a new standard operation sequence exceeds a second threshold, and the total extraction time exceeds a third threshold.

[0077] During the learning phase, when a standard operation sequence that meets the user's preset dimension is stored in the database, a stopping condition needs to be met before the standard operation sequence can be stopped from being stored in the database.

[0078] The maximum number of repetitions of each standard operation sequence stored in the database can be set, which is defined as the first threshold; the time when the standard operation sequence is no longer stored in the database is defined as the second threshold; the total duration of storing the standard operation sequence in the database is defined as the third threshold.

[0079] The stopping conditions include the number of repetitions of each standard operation sequence exceeding a first threshold, the time without a new standard operation sequence exceeding a second threshold, and the total extraction time exceeding a third threshold. The extraction of standard operation sequences can be stopped if any one of the three stopping conditions is met.

[0080] In one embodiment, the dimensionality of a sequence can be changed based on user needs, including dimensionality reduction and dimensionality increase. When a user wants to reduce the dimensionality of an operation sequence, they simply delete the corresponding high-dimensional operation sequence. For example, to change a three-dimensional operation sequence to a two-dimensional one, the three-dimensional operation sequence in the database must be deleted.

[0081] If the user wishes to increase the dimensionality of an operation sequence, they can expand the database and add the corresponding higher-dimensional sequence information. For example, to change a two-dimensional operation sequence to a three-dimensional one, they first need to expand and optimize the database, reanalyze the sequence information from all sequences in the original database, and generate the required high-dimensional sequence. The larger the data volume and the higher the dimensionality, the longer the generation process will take. Therefore, when changing the sequence dimensionality, it is necessary to define different dimensionality limits and decide whether to enable them based on the computing and storage capabilities of different devices.

[0082] S420: Cache the industrial operation instructions received in chronological order to obtain industrial control business sequences of different dimensions. Refer to step S310 of the above embodiment.

[0083] S430: Based on known standard operation sequences of different dimensions, for each dimension, each industrial operation instruction of the industrial control business sequence of the same dimension is sequentially compared with the standard operation sequence of the same dimension one by one.

[0084] In one embodiment, for each dimension, according to the standard operation sequence of the dimension corresponding to the address information, the industrial control service sequence of the dimension corresponding to the address information and the standard operation sequence of the dimension corresponding to the address information may be compared one by one in sequence.

[0085] Address information includes the source and destination addresses, specifically the sender and receiver addresses of industrial operation instructions. Assuming there are a large number of industrial devices, the industrial control business sequence and standard operation sequence involved in the comparison must ensure the same address information. This means they are a sequence of industrial operation instructions from the same upstream terminal to the same downstream industrial device. To determine whether an industrial control business sequence of a certain dimension matches a standard operation sequence of the same dimension, it is necessary to compare each work operation instruction contained in the industrial control business sequence with the standard operation sequence for consistency, including the content and order of the work operation instructions within the sequence. The work operation instruction content includes address information.

[0086] S440: If the industrial control business sequence of any dimension is consistent with any standard operation sequence of the same dimension, then the industrial control business sequence of the dimension matches the standard operation sequence of the dimension; S450: If the industrial control business sequence of any dimension is inconsistent with any standard operation sequence of the same dimension, then the industrial control business sequence of the dimension does not match the standard operation sequence of the dimension.

[0087] S460: If the industrial control service sequence of any dimension does not match the standard operation sequence, perform a security control operation.

[0088] like Figure 6 As shown, when there are multiple industrial control business sequences of different dimensions, you can first search and match the one-dimensional sequence. If there is no match, an alarm blocking is performed; if the match is successful, then search and match the two-dimensional sequence. If there is no match, an alarm blocking is performed; if the match is successful, then search and match the three-dimensional sequence. And so on, search and match the N-dimensional sequence. Only when all matches are successful can it be considered to have passed the review and be sent to the downstream industrial equipment.

[0089] It should be noted that when prompts, alarms, and blocking operations occur, if they are compliant sequences after manual verification by the user, these operation sequences can be stored in the database as standard operation sequences. For scenarios that require security control, a serialized automatic editing solution can be added to not only refresh and add rules for the current state, but also add and refresh sequence rules for adjacent states. For example: when it is necessary to perform a whitelist operation on an alarm, that is, add it to the industrial control whitelist and consider it a standard operation sequence, for example, for the ABDEXY sequence, assuming that the alarm has the E instruction, when the sequence analysis dimension is 3, then BDE, DEX, EXY, DE, EX, and E can all be added to the database as standard operation sequences.

[0090] Please refer to Figure 7 , which is a schematic diagram of the structure of the industrial operation safety control device provided by an embodiment of the present application. Figure 7 As shown, the safety control device 700 for industrial operations may include:
