Description

Technical Field

[0001] The present invention relates to the technical field of chemical production safety monitoring, and in particular to a chemical production enterprise safety monitoring method and system. Background Art

[0002] Due to its special nature, the chemical industry has strict production control requirements for chemical companies. Safety control of chemical production is the most important component. Chemical safety is not only a basic condition factor necessary for enterprise production, but also a basic element to maintain the safety of enterprises and surrounding activities.

[0003] At present, for chemical production enterprises, safety supervision is mainly carried out through inspections, reviews, and supervision. At present, most of them are still completed manually, and there are large deviations in judgment and other human errors that lead to unsatisfactory safety monitoring results. At the same time, since different types of operations are involved in the chemical production process, the aspects involved in safety monitoring are also relatively many and different. For chemical production, the ultimate goal of safety control management is to ensure that production can proceed smoothly, so safety monitoring should also be carried out around this goal. However, most of the current safety monitoring content of chemical companies is not classified and is relatively chaotic.

[0004] Therefore, designing a safety monitoring method and system for chemical production enterprises to achieve reasonable and effective safety monitoring of chemical production through reasonable risk classification and risk assessment is an urgent problem to be solved. Summary of the invention

[0005] The purpose of the present invention is to provide a safety monitoring method for chemical production enterprises, by continuously collecting relevant identification information after the occurrence of risks to distinguish different risk types in a standardized manner, establish a risk identification information database for chemical production safety, and at the same time, perform reasonable analysis and processing of relevant information on the risk identification information in the risk identification information database, and use the risk matrix as a risk identification analysis method to reasonably and accurately complete the level confirmation of many risks of different types, so that when conducting safety monitoring of chemical production, reasonable risk monitoring and disposal can be carried out according to the established risk level table. On the one hand, the established risk level table provides most of the risk points involved in chemical production safety, which is conducive to enterprises to establish reasonable disposal plans for these risk points in advance, and can quickly identify risks, so that the disposal of risks is more targeted and effective. On the other hand, it also guides enterprises to establish reasonable risk response policies according to different levels of risks in the process of chemical production, while fully ensuring reasonable control of risks, it can also avoid unreasonable economic and resource consumption caused by blind disposal due to inadequate risk identification, greatly optimizing the management cost of risk control in the chemical production process, and making the risk management of enterprises more efficient.

[0006] The purpose of the present invention is also to provide a safety monitoring system for chemical production enterprises, which is configured to provide risk identification information collection to establish a risk identification information database, and implement risk level analysis based on the risk matrix based on the risk identification database, thereby providing reasonable guidance and disposal equipment and facilities for real-time risk detection in chemical production, and providing a stable material basis for the reasonable and efficient realization of chemical production safety monitoring.

[0007] In a first aspect, the present invention provides a safety monitoring method for a chemical production enterprise, comprising collecting risk identification information, performing information normalization processing, and establishing a risk identification information database; extracting risk identification information from the risk identification information database, establishing a risk level based on a risk matrix, and forming a risk level table; acquiring real-time risk information, and confirming the risk level in combination with the risk identification information database and the risk level table to form risk level warning information.

[0008] In the present invention, the method continuously collects relevant identification information after the occurrence of risks to distinguish different risk types in a standardized manner, establishes a risk identification information base for chemical production safety, and at the same time performs reasonable analysis and processing of relevant information on the risk identification information in the risk identification information base, and uses the risk matrix as a way of risk identification and analysis to reasonably and accurately complete the level confirmation of many risks of different types. In this way, when conducting safety monitoring of chemical production, reasonable risk monitoring and disposal can be carried out according to the established risk level table. On the one hand, the established risk level table provides most of the risk points involved in chemical production safety, which is conducive to enterprises to establish reasonable disposal plans for these risk points in advance, and can quickly identify risks, so that risk disposal is more targeted and effective. On the other hand, it also guides enterprises to establish reasonable risk response policies according to different levels of risks in the process of chemical production. While fully ensuring reasonable control of risks, it can also avoid unreasonable economic and resource consumption caused by blind disposal due to inadequate risk identification, greatly optimizing the management cost of risk control in the chemical production process, and making the risk management of enterprises more efficient.

[0009] As a possible implementation method, risk identification information is collected, and information is standardized and processed to establish a risk identification information database, including: classifying and calibrating the different risk identification information collected to form risk identification information for people, risk identification information for equipment and facilities, risk identification information for materials, risk identification information for processes, and risk identification information for the environment; standardizing different types of risk identification information to form basic information for human risk identification, basic information for equipment and facilities risk identification, basic information for material risk identification, basic information for process risk identification, and basic information for environmental risk identification; and combining basic information for human risk identification, basic information for equipment and facilities risk identification, basic information for material risk identification, basic information for process risk identification, and basic information for environmental risk identification to establish a risk identification information database.

[0010] In the present invention, the establishment of the risk identification information database is the data basis for the subsequent determination of the risk level of risk information. For chemical production enterprises, safe production is the content that enterprises should focus on controlling, so the departments related to safe production will record the risks that occur and the impact of the risks, and then the risk identification information can be collected based on these recorded information. It should be noted that for risks, on the one hand, there are differences in the information of risk identification for different types of risks. If the collection and processing of different types of risk identification information are carried out in general, the information analysis will not be in-depth, and then the risk cannot be accurately determined when the risk is identified based on the extracted information in the future. On the other hand, for different types of risks, there will be differences in the disposal and focus of risks. If the risk identification information is not distinguished by type, it is impossible to carry out reasonable and orderly management and control in the future when risk identification is carried out based on these extracted risk information, resulting in a waste of management resources and an increase in management costs. Therefore, when establishing a risk identification information database, it is necessary to classify the risk identification information reasonably. Here, the classification of risk identification information is mainly distinguished from the source of risk, including five aspects: human, equipment and facilities, materials, process and working environment. What needs to be explained here is that the risk identification information collected by this application is mainly for chemical production, that is, starting from the safety of chemical production, risk identification information that affects the safety of chemical production is collected, such as communication disputes caused by the personality of personnel that have no impact on production, damage to spare monitoring equipment, fluctuations in material costs, process improvements, and irrelevant changes in the environment are not included in the scope of risk identification information. In this way, it can be ensured that the risk identification information in the established risk identification library is completely related to the safety of chemical production. In addition, considering that the collected risk identification information itself has a certain content, and the content is relatively complicated, it is not conducive to subsequent reasonable extraction and processing analysis, so it is necessary to standardize it after collection.

[0011] As a possible implementation method, different types of risk identification information are standardized and processed to form basic information for human risk identification, basic information for equipment and facility risk identification, basic information for material risk identification, basic information for process risk identification and basic information for environmental risk identification, including: the following standardized processing is performed on human risk identification information: extracting the prior certification information of the same risk identification information to form human risk identification feature information; extracting the scope of incidents involving the same risk identification information to form the following human risk impact scope information: human impact average productivity, human impact average cost rate and human impact average cycle rate; extracting the post-processing information of the same risk identification information to form the following human risk processing information; The equipment and facilities risk identification information is processed as follows: the parameter information of the same risk identification information is extracted to form the risk identification characteristic information of the equipment and facilities; the scope of the incident of the same risk identification information is extracted to form the following equipment and facility risk impact scope information: the average productivity of the equipment and facilities, the average cost rate of the equipment and facilities, and the average cycle rate of the equipment and facilities; the post-event disposal information of the same risk identification information is extracted to form the following equipment and facility risk disposal characteristic information. Information: average cost rate of equipment and facility disposal and average time rate of equipment and facility disposal; combined with the corresponding equipment and facility risk identification feature information, equipment and facility risk impact range information and equipment and facility risk disposal feature information, different basic information for equipment and facility risk identification is formed; the risk identification information of materials is processed as follows: parameter information of the same risk identification information is extracted to form material risk identification feature information; the scope information of the incidents of the same risk identification information is extracted to form the following material risk impact range information: average productivity of material impact, average cost rate of material impact and average cycle rate of material impact; post-processing information of the same risk identification information is extracted to form the following material risk disposal feature information: material The average cost rate of disposal and the average time rate of material disposal; combine the corresponding material risk identification feature information, material risk impact range information and material risk disposal feature information to form different basic information for material risk identification; perform the following regularization processing on the process risk identification information: extract parameter information of the same risk identification information to form process risk identification feature information; extract the scope information of the same risk identification information to form the following process risk impact range information: average productivity of process impact, average cost rate of process impact and average cycle rate of process impact; extract the post-process disposal information of the same risk identification information to form the following process risk disposal feature information: average cost rate of process disposal and average time rate of process disposal;Combine the corresponding process risk identification feature information, process risk impact range information and process risk disposal feature information to form different process risk identification basic information; perform the following regularization processing on the environmental risk identification information: extract parameter information of the same risk identification information to form environmental risk identification feature information; extract the incident scope information of the same risk identification information to form the following environmental risk impact range information: average environmental impact productivity, average environmental impact cost rate and average environmental impact cycle rate; extract the post-processing information of the same risk identification information to form the following environmental risk disposal feature information: average environmental disposal cost rate and average environmental disposal time rate; combine the corresponding environmental risk identification feature information, environmental risk impact range information and environmental risk disposal feature information to form different environmental risk identification basic information. ;

[0012] In the present invention, the extracted risk identification information is standardized according to different types, and the content of the standardized processing includes two aspects. On the one hand, the characteristic information used to identify the risk in the risk identification information is extracted. For the risks caused by human factors, the extraction of risk identification characteristic information is mainly through the proof information left, which includes but is not limited to the signed work card, the input control information in the production system, the communication information with the relevant operators in the production system, and the video monitoring information on the scene. Of course, the feature extraction of this information also needs to be reasonably extracted based on language features and image features, so as to form more targeted and accurate characteristic information. For the extraction of risk identification characteristic information of risk identification information of equipment, facilities, materials, processes and environment, it is considered that the information affecting the safety of chemical production is the control quantity information that affects the production, so the extraction of these types of risk identification characteristic information is the extraction of control parameters, and the extracted characteristic information includes but is not limited to the range quantity, control function, rate of change, etc., and the control form of production is determined specifically by the corresponding control parameters. Of course, since risk identification is the identification of specific risk events, different risk identification information under the same type is the information collection of events caused by the risk impact caused by the change of a single control parameter. On the other hand, the extraction of risk identification information is conducive to the subsequent reasonable prejudgment and foresight of the risks generated in the real-time production process, while the probability of risk occurrence and the size of the impact of risk on production need to be further extracted to determine the risk information. After all, the probability of risk occurrence and the size of the impact of risk not only determine the reasonable risk monitoring in the production process, but also provide a reference for the reasonable response to the possible impact of risk. It can be understood that the risk identification information collected in this application is information that has a direct impact on production. The occurrence of risk will inevitably cause the impact of production on output, cost, and cycle. Therefore, the probability of risk occurrence and the impact of risk are also based on their impact on output, cost, and cycle. Here, the impact on average productivity is the ratio of the average impact on output relative to the total average output when the same risk occurs in history, the impact on average cost rate is the ratio of the average impact on cost relative to the total average cost when the same risk occurs in history, and the impact on average cycle law is the ratio of the average impact on the production cycle relative to the total average production cycle when the same risk occurs in history. In addition, the occurrence of risks will also lead to risk disposal responses. The average cost rate and average time rate generated by risk disposal are also indicators to measure the impact of risks. The average cost rate of disposal is the ratio of the cost incurred by disposal after the same risk occurs to the total average cost of production. The average time rate of disposal is the ratio of the time for disposal after the same risk occurs to the total average time of production.Based on the risk identification information, feature information, impact information and disposal information are collected to form the basic information of the corresponding risk.

[0013] As a possible implementation method, risk identification information is extracted from the risk identification information database, and risk levels are established based on the risk matrix to form a risk level table, including: extracting different risk identification basic information from the risk identification information database, and conducting risk probability analysis based on process steps to form corresponding risk probability information; extracting different risk identification basic information from the risk identification information database, and conducting risk size analysis based on process steps to form corresponding risk size information; conducting risk assessment based on the risk probability information and risk size information corresponding to different risk identification basic information, and establishing a risk level table.

[0014] In the present invention, the risk matrix is ​​a common means of risk level assessment for risks, and when performing risk level assessment, it is necessary to reasonably determine how to obtain the corresponding risk probability information and the impact information generated by the risk. The common way to obtain the risk probability is to determine the number of times the risk occurs under the total number of cumulative statistical events, and the risk impact size is basically assessed by a preset evaluation value. However, on the one hand, the probability of different types of risks is considered, and not all risks can be obtained by statistics of independent events. On the other hand, the assessment of the risk size is based on the assessment and preset, and the impact size cannot be accurately reflected. After all, the reference level for comparison is a preset evaluation value, which has a certain hypothesis and there is a verification of rationality. This application is based on the characteristics of chemical production, and uses the characteristics of chemical production to reasonably define the probability of occurrence of risks and quantify the impact size, so as to achieve a more accurate and reasonable level determination.

[0015] As a possible implementation method, different risk identification basic information in the risk identification information library is extracted, and risk probability analysis based on the process steps is performed to form corresponding risk probability information, including: setting a probability analysis cycle, and determining different processes of the production process and processes corresponding to different risk identification basic information in the risk identification information library, to form different process risk identification basic information sets; for the human risk identification basic information in the process risk identification basic information set, the number of behaviors within the probability analysis cycle is judged according to the corresponding human risk identification feature information, the frequency of risk occurrence is determined, and the corresponding probability of human risk occurrence is formed; for the equipment and facility risk identification basic information in the process risk identification basic information set, the parameters within the probability analysis cycle are determined according to the corresponding equipment and facility risk identification feature information. The effective time ratio of risk occurrence is determined to form the corresponding equipment and facility risk occurrence probability; for the material risk identification basic information in the process risk identification basic information set, the effective time ratio of parameter risk occurrence within the probability analysis period is determined according to the corresponding material risk identification characteristic information, to form the corresponding material risk occurrence probability; for the process risk identification basic information in the process risk identification basic information set, the effective time ratio of parameter risk occurrence within the probability analysis period is determined according to the corresponding process risk identification characteristic information, to form the corresponding process risk occurrence probability; for the environmental risk identification basic information in the process risk identification basic information set, the effective time ratio of parameter risk occurrence within the probability analysis period is determined according to the corresponding environmental risk identification characteristic information, to form the corresponding environmental risk occurrence probability.

[0016] In the present invention, for chemical production, the occurrence of risk is also related to the importance of different processes. When conducting reasonable production safety monitoring, enterprises will consider limited resources and costs, and will distinguish between key and secondary risk monitoring. The level assessment is also a reasonable division of the importance of risks to provide guidance for reasonable risk management. Therefore, when obtaining quantitative data on the probability of risk occurrence, the situation of the process is fully considered, and the probability of different risks is determined for different processes. In each process, whether it is human operation, operation and control of equipment and facilities, addition of materials, implementation of process and control of environmental parameters, they are all independent events. Therefore, when quantifying the probability, for human risk, the ratio of the number of times the operation risk occurs to the total number of operations in a reasonable analysis cycle is used as the probability quantification of risk occurrence. For equipment and facilities, considering that the control of production by equipment and facilities in the process is continuous, the ratio of the duration of parameter risk occurrence to the total duration of parameter normal production is used as the indicator of probability quantification. For materials, the ratio of the duration of material parameter change risk to the duration of normal material parameter is used as the indicator of operation probability quantification. For process, the ratio of the duration of process parameter risk occurrence to the duration of normal process parameter occurrence is used as the indicator of probability quantification. For environment, the ratio of the duration of environmental parameter risk occurrence to the duration of normal environmental parameter occurrence is used as the indicator of probability quantification. Such probability determination can fit different types of parameter data and can also realize the embodiment of accurate probability quantification data of non-preset evaluation. Ensure the accuracy and rationality of risk probability determination and adaptability to different types of risks.

[0017] As a possible implementation method, extract different risk identification basic information from the risk identification information database, and conduct risk size analysis based on the process steps to form corresponding risk size information, including: for different processes, determine the corresponding average process operation time Enter the total number of items Total number of output materials Total number of monitoring parameters And the total amount of process materials v represents the number of different processes; according to the average process operation time corresponding to different processes Enter the total number of items Total number of output materials Total number of monitoring parameters And the total amount of process materials Determine the importance of different processes in the production process in: Get the average productivity of human impact of different human risk identification basic information in the process risk identification basic information set under the corresponding process Average cost rate of human impact Average cycle rate of human impact Average cost rate of human disposal And the average time rate of human treatment Combined with the process importance of the corresponding process Determine the risk amount corresponding to different human risks m is the number of the basic information for identifying different human risks under the process numbered v, where: Obtain the average productivity of the equipment and facilities that affect the risk identification basic information of different equipment and facilities in the process risk identification basic information set under the corresponding process Equipment and facilities affect the average cost rate Average cycle rate of equipment and facilities impact Average cost rate of equipment and facility disposal And the average time rate of equipment and facilities disposal Combined with the process importance of the corresponding process Determine the risk amount corresponding to different equipment and facility risks n is the number of the basic information for risk identification of different equipment and facilities under the process numbered v, where: Get the average productivity of materials that affect different material risk identification basic information in the process risk identification basic information set under the corresponding process Material impact average cost rate Average cycle rate of material impact Average cost rate of material disposal And the average material handling time Combined with the process importance of the corresponding process Determine the risk amount corresponding to different material risks i is the number of the basic information for risk identification of different materials under the process numbered v, where: Obtain the average productivity of the process impact of different process risk identification basic information in the process risk identification basic information set under the corresponding process Process affects average cost rate Process influences average cycle rate Average cost rate of process disposal And the average time rate of process treatment Combined with the process importance of the corresponding process Determine the risk amount corresponding to different process risks k is the number of the basic information for identifying different process risks under the process numbered v, where: Obtain the average productivity of environmental impact of different environmental risk identification basic information in the process risk identification basic information set under the corresponding process Average cost rate of environmental impact Average cycle rate of environmental impact Average cost rate of environmental disposal And the average time rate of environmental treatment Combined with the process importance of the corresponding process Determine the amount of risk corresponding to different environmental risks r is the number of the basic information for identifying different environmental risks under the process numbered v, where:

[0018] In the present invention, the quantification of the risk impact is based on the historical occurrence of risks, including output, cost, cycle, cost and cycle consumed by disposal, and the importance of different processes. It should be noted that the quantification of the importance of the process is evaluated by the operation time, input material items, output material items, monitoring parameter quantity and total process material quantity of the process. After all, for chemical processes, the longer the time consumed, the more complex the reaction, the higher the stability of the reaction parameters that need to be guaranteed, the more material items required for the reaction, the more output material items, the more complex the reaction, the more complex the classification and extraction of the substances formed by the reaction, the more parameters monitored by the reaction, the higher the difficulty of maintaining the stability of the reaction, the more total reaction materials, the larger the volume of the reaction, and the more difficult the stability to be guaranteed by the reaction, so the importance is proportional to the change value of these parameters, which is very accurate and reasonable for quantifying the importance of the process. The output, cycle, cost, cost of disposal and cycle of disposal of the risk impact are also proportional to the size of the risk impact, so it is accurate and reasonable to evaluate the size of the risk based on these data.

[0019] As a possible implementation method, risk assessment is carried out according to the risk probability information and risk size information corresponding to different risk identification basic information, and a risk level table is established, including: According to the importance of the process Establish process risk levels from large to small; Under different process risk levels, obtain the probability of occurrence of human risks corresponding to different human risks in the corresponding process and risk amount And form the process artificial grade value in, Under different process risk levels, obtain the probability of occurrence of human equipment and facility risks corresponding to different equipment and facility risks in the corresponding process and risk amount And form the process equipment and facility grade value in, Under different process risk levels, obtain the material risk occurrence probability corresponding to different material risks in the corresponding process and risk amount And form the process material grade value in, Under different process risk levels, obtain the process risk occurrence probability corresponding to different process risks in the corresponding process and risk amount And form the process level value in, Under different process risk levels, obtain the probability of occurrence of environmental risks corresponding to different environmental risks in the corresponding process and risk amount And form the process environment level value in, For different human risks in the process risk level, according to the corresponding process human level value Sort the processes from large to small, and assign human risk levels to the processes according to the rankings; for different equipment and facility risks in the process risk levels, assign the corresponding process equipment and facility level values Sort the process from large to small, and assign risk levels to the process equipment and facilities according to the ranking; for different material risks in the process risk level, assign risk levels according to the corresponding process material level values. Sort the process materials from large to small and assign risk levels to the process materials in turn according to the ranking; for different process risks in the process risk level, assign risk levels according to the corresponding process process level values. Sort the processes from large to small and assign process risk levels according to the ranking; for different environmental risks in the process risk level, assign a corresponding process environmental level value Sort the processes from large to small, and assign process environmental risk levels according to the ranking; combine the process human risk level, process equipment and facility risk level, process technology risk level and process environmental risk level under different process risk levels to form a risk level table.

[0020] In the present invention, it can be understood that the probability of risk occurrence and the magnitude of risk impact are two dimensions of risk assessment, and both often determine the attention paid by enterprises to different risks in production safety monitoring, so it is necessary to comprehensively consider the two when determining the risk level. In addition, for production safety, different risk types require different responses, and this response is also sequential. For example, human life and property are above all else, so when a person is at risk, the first thing to do is to get rid of the risk. Therefore, when conducting a level assessment, it is also based on different types of risks in different processes. Different assessments are made, which is beneficial to showing more risk types under the corresponding risk levels on the one hand, and on the other hand, it is also beneficial to guide enterprises to provide different types of risk attention when conducting production safety monitoring, better help enterprises to allocate resources and control costs for risk monitoring, and make the enterprise's risk management more efficient.

[0021] As a possible implementation method, real-time risk information is obtained, and the risk level is confirmed in combination with the risk identification information library and the risk level table to form risk level warning information, including: for different process steps, obtaining real-time information on human behavior, real-time parameter information on equipment and facilities, real-time parameter information on materials, real-time parameter information on processes, and real-time parameter information on the environment in the corresponding process; according to different types of real-time information corresponding to different processes, risks are confirmed in combination with the risk identification information library and the risk level table to form corresponding risk level warning information.

[0022] In the present invention, the purpose of establishing risk levels is, on the one hand, to provide enterprises with the focus of production safety monitoring and the reasonable arrangement of monitoring resources, and on the other hand, to identify different risks in advance. In risk monitoring, based on the focus of risk levels, real-time data collection with identification information as a reference can achieve more accurate and efficient monitoring and early warning of risks.

[0023] As a possible implementation method, according to the different types of real-time information corresponding to different processes, risks are confirmed in combination with the risk identification information library and the risk level table to form corresponding risk level warning information, including: obtaining the real-time information of human behavior corresponding to the process, and matching it with the human risk identification feature information of the corresponding process. If there is a match between the real-time information of human behavior and the human risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output; obtaining the real-time parameter information of equipment and facilities corresponding to the process, and matching it with the equipment and facility risk identification feature information of the corresponding process. If there is a match between the real-time parameter information of equipment and facilities and the equipment and facility risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output; obtaining the real-time parameter information of the process The corresponding material real-time parameter information is obtained, and a matching comparison is made with the material risk identification feature information of the corresponding process. If the material real-time parameter information matches the material risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output; the process real-time parameter information corresponding to the process is obtained, and a matching comparison is made with the process risk identification feature information of the corresponding process. If the process real-time parameter information matches the process risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output; the environment real-time parameter information corresponding to the process is obtained, and a matching comparison is made with the environment risk identification feature information of the corresponding process. If the environment real-time parameter information matches the environment risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output.

[0024] In the present invention, of course, when conducting monitoring and early warning, for different types of risk information, only when it fully matches the identification information can it be determined that the risk may occur. The level table can be used to reasonably arrange and deal with resources based on the results of risk identification, making the company's production safety monitoring more reasonable and effective.

[0025] In a second aspect, the present invention provides a safety monitoring system for a chemical production enterprise, which is configured to: collect risk identification information, perform information normalization processing, and establish a risk identification information database; extract risk identification information in the risk identification information database, establish risk levels based on the risk matrix, and form a risk level table; obtain real-time risk information, and confirm the risk level in combination with the risk identification information database and the risk level table to form risk level warning information.

[0026] In the present invention, the system is configured to provide risk identification information collection to establish a risk identification information database, and implement risk level analysis based on the risk matrix based on the risk identification database, thereby providing reasonable guidance and disposal equipment and facilities for real-time risk detection in chemical production, and providing a stable material basis for the reasonable and efficient realization of chemical production safety monitoring.

[0027] The beneficial effects of a chemical production enterprise safety monitoring method and system provided by the present invention are:

[0028] The method continuously collects relevant identification information after the occurrence of risks to distinguish different risk types in a standardized manner, establishes a risk identification information database for chemical production safety, and at the same time performs reasonable analysis and processing of relevant information on the risk identification information in the risk identification information database, and uses the risk matrix as a way of risk identification analysis to reasonably and accurately complete the level confirmation of many risks of different types. In this way, when conducting safety monitoring of chemical production, reasonable risk monitoring and disposal can be carried out according to the established risk level table. On the one hand, the established risk level table provides most of the risk points involved in chemical production safety, which is conducive to enterprises to establish reasonable disposal plans for these risk points in advance, and can quickly identify risks, making risk disposal more targeted and effective. On the other hand, it also guides enterprises to establish reasonable risk response policies according to different levels of risks in the process of chemical production. While fully ensuring reasonable control of risks, it can also avoid unreasonable economic and resource consumption caused by blind disposal due to inadequate risk identification, greatly optimizing the management cost of risk control in the chemical production process, and making the risk management of enterprises more efficient.

[0029] The system is configured to provide risk identification information collection to establish a risk identification information database, and implement risk level analysis based on the risk matrix based on the risk identification database, providing reasonable guidance and disposal equipment and facilities for real-time risk detection in chemical production, and providing a stable material basis for the reasonable and efficient realization of chemical production safety monitoring.

[0030] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for use in the embodiments of the present invention are briefly introduced below. It should be understood that the following drawings only show certain embodiments of the present invention and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without creative work.

[0031] Figure 1 A step diagram of a chemical production enterprise safety monitoring method provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Due to its special nature, the chemical industry has strict production control requirements for chemical companies. Safety control of chemical production is the most important component. Chemical safety is not only a basic condition factor necessary for enterprise production, but also a basic element to maintain the safety of enterprises and surrounding activities.

[0034] At present, for chemical production enterprises, safety supervision is mainly carried out through inspections, reviews, and supervision. At present, most of them are still completed manually, and there are large deviations in judgment and other human errors that lead to unsatisfactory safety monitoring results. At the same time, since different types of operations are involved in the chemical production process, the aspects involved in safety monitoring are also relatively many and different. For chemical production, the ultimate goal of safety control management is to ensure that production can proceed smoothly, so safety monitoring should also be carried out around this goal. However, most of the current safety monitoring content of chemical companies is not classified and is relatively chaotic.

[0035] refer to Figure 1 The embodiment of the present invention provides a safety monitoring method for a chemical production enterprise. The method continuously collects relevant identification information after a risk occurs to perform standardized processing to distinguish different risk types, establishes a risk identification information database for chemical production safety, and performs reasonable analysis and processing of relevant information on the risk identification information in the risk identification information database. The risk matrix is ​​used as a risk identification and analysis method to reasonably and accurately complete the level confirmation of many risks of different types. In this way, when performing safety monitoring of chemical production, reasonable risk monitoring and disposal can be performed according to the established risk level table. On the one hand, the established risk level table provides most of the risk points involved in chemical production safety, which is conducive to the enterprise to establish a reasonable disposal plan for these risk points in advance, and can quickly identify risks, so that the disposal of risks is more targeted and effective. On the other hand, it also guides the enterprise to establish a reasonable risk response policy according to different levels of risks in the process of chemical production. While fully ensuring the reasonable control of risks, it can also avoid the unreasonable consumption of economy and resources caused by blind disposal due to inadequate risk identification, greatly optimizing the management cost of risk control of enterprises in the process of chemical production, and making the risk management of enterprises more efficient.

[0036] The safety monitoring method for chemical production enterprises specifically includes the following steps:

[0037] S1: Collect risk identification information, conduct information standardization processing, and establish a risk identification information database.

[0038] Collect risk identification information, conduct information standardization processing, and establish a risk identification information database, including: classify and calibrate the different risk identification information collected to form risk identification information for people, risk identification information for equipment and facilities, risk identification information for materials, risk identification information for processes, and risk identification information for the environment; standardize different types of risk identification information to form basic information for human risk identification, basic information for equipment and facilities risk identification, basic information for material risk identification, basic information for process risk identification, and basic information for environmental risk identification; and gather basic information for human risk identification, basic information for equipment and facilities risk identification, basic information for material risk identification, basic information for process risk identification, and basic information for environmental risk identification to establish a risk identification information database.

[0039] The establishment of the risk identification information database is the data basis for the subsequent determination of the risk level of risk information. For chemical production enterprises, safe production is the key content that enterprises need to control. Therefore, the departments related to safe production will record the risks that occur and the impact of the risks, and then collect risk identification information based on these recorded information. It should be noted that, for risks, on the one hand, there are differences in risk identification information for different types of risks. If different types of risk identification information are collected and processed in a general way, the information analysis will not be in-depth, and then the risk cannot be accurately determined when the risk is identified based on the extracted information in the future. On the other hand, for different types of risks, there will be differences in risk handling and focus. If the risk identification information is not differentiated by type, it will be impossible to carry out reasonable and orderly management and control when risk identification is carried out based on these extracted risk information, resulting in a waste of management resources and an increase in management costs. Therefore, when establishing a risk identification information database, it is necessary to reasonably classify the risk identification information. Here, the classification of risk identification information is mainly distinguished from the source of risk, including five aspects: human, equipment and facilities, materials, process and working environment. What needs to be explained here is that the risk identification information collected by this application is mainly for chemical production, that is, starting from the safety of chemical production, risk identification information that affects the safety of chemical production is collected, such as communication disputes caused by the personality of personnel that have no impact on production, damage to spare monitoring equipment, fluctuations in material costs, process improvements, and irrelevant changes in the environment are not included in the scope of risk identification information. In this way, it can be ensured that the risk identification information in the established risk identification library is completely related to the safety of chemical production. In addition, considering that the collected risk identification information itself has a certain content, and the content is relatively complicated, it is not conducive to subsequent reasonable extraction and processing analysis, so it is necessary to standardize it after collection.

[0040] Different types of risk identification information are standardized and processed to form basic information for human risk identification, basic information for equipment and facility risk identification, basic information for material risk identification, basic information for process risk identification and basic information for environmental risk identification, including: the following standardized processing is performed on human risk identification information: prior certification information of the same risk identification information is extracted to form characteristic information for human risk identification; the scope of incidents of the same risk identification information is extracted to form the following human risk impact scope information: average productivity of human impact, average cost rate of human impact and average cycle rate of human impact; post-processing information of the same risk identification information is extracted to form the following characteristic information for human risk processing: average cost rate of human processing and average time of human processing. rate; combine the corresponding artificial risk identification feature information, artificial risk impact range information and artificial risk disposal feature information to form different artificial risk identification basic information; perform the following regularization processing on the risk identification information of equipment and facilities: extract parameter information of the same risk identification information to form equipment and facility risk identification feature information; extract the scope information of the same risk identification information to form the following equipment and facility risk impact range information: average productivity of equipment and facility impact, average cost rate of equipment and facility impact and average cycle rate of equipment and facility impact; extract the post-event disposal information of the same risk identification information to form the following equipment and facility risk disposal feature information: average cost rate of equipment and facility disposal and average time rate of equipment and facility disposal; combine the corresponding equipment The facility risk identification characteristic information, equipment and facility risk impact range information and equipment and facility risk disposal characteristic information form different basic information for equipment and facility risk identification; the material risk identification information is processed as follows: the parameter information of the same risk identification information is extracted to form the material risk identification characteristic information; the incident scope information of the same risk identification information is extracted to form the following material risk impact range information: the average productivity of material impact, the average cost rate of material impact and the average cycle rate of material impact; the post-event disposal information of the same risk identification information is extracted to form the following material risk disposal characteristic information: the average cost rate of material disposal and the average time rate of material disposal; the corresponding material risk identification characteristic information and material risk impact range information are combined to form the material risk disposal characteristic information. and material risk disposal characteristic information to form different basic information for material risk identification; the risk identification information of the process is subjected to the following regularization processing: the parameter information of the same risk identification information is extracted to form the process risk identification characteristic information; the scope information of the same risk identification information is extracted to form the following process risk impact scope information: the average productivity of process impact, the average cost rate of process impact and the average cycle rate of process impact; the post-process disposal information of the same risk identification information is extracted to form the following process risk disposal characteristic information: the average cost rate of process disposal and the average time rate of process disposal; different basic information for process risk identification is formed by combining the corresponding process risk identification characteristic information, process risk impact scope information and process risk disposal characteristic information;The following regularization processing is performed on the environmental risk identification information: extract parameter information of the same risk identification information to form environmental risk identification feature information; extract the scope of the incident of the same risk identification information to form the following environmental risk impact range information: average environmental impact productivity, average environmental impact cost rate and average environmental impact cycle rate; extract the post-processing information of the same risk identification information to form the following environmental risk disposal feature information: average environmental disposal cost rate and average environmental disposal time rate; combine the corresponding environmental risk identification feature information, environmental risk impact range information and environmental risk disposal feature information to form different environmental risk identification basic information. ;

[0041] The extracted risk identification information is standardized according to different types, and the content of the standardized processing includes two aspects. On the one hand, the characteristic information used to identify risks in the risk identification information is extracted. For risks caused by human factors, the extraction of risk identification characteristic information is mainly through the proof information left, which includes but is not limited to the signed work card, the input control information in the production system, the communication information with relevant operators in the production system, and the video monitoring information on site. Of course, the feature extraction of this information also needs to be reasonably extracted based on language features and image features, so as to form more targeted and accurate characteristic information. For the extraction of risk identification characteristic information of risk identification information such as equipment, facilities, materials, processes and environment, it is considered that the information affecting the safety of chemical production is the control quantity information that affects the production. Therefore, the extraction of these types of risk identification characteristic information is the extraction of control parameters. The extracted characteristic information includes but is not limited to the range quantity, control function, change rate, etc., and the control form of production is determined by the corresponding control parameters. Of course, since risk identification is the identification of specific risk events, different risk identification information under the same type is the information collection of events caused by the risk impact of changes in a single control parameter. On the other hand, the extraction of risk identification information is conducive to the subsequent reasonable prejudgment and foresight of the risks generated in the real-time production process, while the probability of risk occurrence and the size of the impact of risk on production need to be further extracted to determine the risk information. After all, the probability of risk occurrence and the size of the impact of risk not only determine the reasonable risk monitoring in the production process, but also provide a reference for the reasonable response to the possible impact of risk. It can be understood that the risk identification information collected in this application is information that has a direct impact on production. The occurrence of risk will inevitably cause the impact of production on output, cost, and cycle. Therefore, the probability of risk occurrence and the impact of risk are also based on their impact on output, cost, and cycle. Here, the impact on average productivity is the ratio of the average impact on output relative to the total average output when the same risk occurs in history, the impact on average cost rate is the ratio of the average impact on cost relative to the total average cost when the same risk occurs in history, and the impact on average cycle law is the ratio of the average impact on the production cycle relative to the total average production cycle when the same risk occurs in history. In addition, the occurrence of risks will also lead to risk disposal responses. The average cost rate and average time rate generated by risk disposal are also indicators to measure the impact of risks. The average cost rate of disposal is the ratio of the cost incurred by disposal after the same risk occurs to the total average cost of production. The average time rate of disposal is the ratio of the time for disposal after the same risk occurs to the total average time of production.Based on the risk identification information, feature information, impact information and disposal information are collected to form the basic information of the corresponding risk.

[0042] S2: Extract risk identification information from the risk identification information database, establish risk levels based on the risk matrix, and form a risk level table.

[0043] Extract risk identification information from the risk identification information database, establish risk levels based on the risk matrix, and form a risk level table, including: extract different risk identification basic information from the risk identification information database, and conduct risk probability analysis based on process steps to form corresponding risk probability information; extract different risk identification basic information from the risk identification information database, and conduct risk size analysis based on process steps to form corresponding risk size information; conduct risk assessment based on the risk probability information and risk size information corresponding to different risk identification basic information, and establish a risk level table.

[0044] The risk matrix is ​​a common means of assessing the risk level. When assessing the risk level, it is necessary to reasonably determine how to obtain the corresponding probability information of the risk and the impact information of the risk. The common way to obtain the risk probability is to determine the number of times the risk occurs under the total number of cumulative statistical events, and the risk impact size is basically assessed by preset evaluation values. However, on the one hand, the probability of different types of risks is taken into account. Not all risks can be obtained by statistics of independent events. On the other hand, the assessment of the risk size is based on the assessment and preset, and the impact size cannot be accurately reflected. After all, the reference level for comparison is a preset evaluation value, which has certain assumptions and verification of rationality. This application is based on the characteristics of chemical production, and uses the characteristics of chemical production to reasonably define the probability of risk and quantify the impact size, so as to achieve more accurate and reasonable level determination.

[0045] Extract different risk identification basic information from the risk identification information library, and conduct risk probability analysis based on the process steps to form corresponding risk probability information, including: setting a probability analysis cycle, and determining different processes of the production process and processes corresponding to different risk identification basic information in the risk identification information library to form different process risk identification basic information sets; for the human risk identification basic information in the process risk identification basic information set, determine the number of behaviors within the probability analysis cycle based on the corresponding human risk identification feature information, determine the frequency of risk occurrence, and form the corresponding human risk occurrence probability; for the equipment and facility risk identification basic information in the process risk identification basic information set, determine the parameter risk occurrence within the probability analysis cycle based on the corresponding equipment and facility risk identification feature information. The effective time ratio of parameter risk occurrence is determined according to the corresponding material risk identification characteristic information for the material risk identification basic information in the process risk identification basic information set, and the corresponding material risk occurrence probability is formed; the process risk identification basic information in the process risk identification basic information set, the effective time ratio of parameter risk occurrence in the probability analysis period is determined according to the corresponding process risk identification characteristic information, and the corresponding process risk occurrence probability is formed; the environmental risk identification basic information in the process risk identification basic information set, the effective time ratio of parameter risk occurrence in the probability analysis period is determined according to the corresponding environmental risk identification characteristic information, and the corresponding environmental risk occurrence probability is formed.

[0046] For chemical production, the occurrence of risks is also related to the importance of different processes. When conducting reasonable production safety monitoring, enterprises will consider limited resources and costs, and will distinguish between key and secondary risk monitoring. Grade assessment is also a reasonable division of risk importance to provide guidance for reasonable risk management. Therefore, when obtaining quantitative data on the probability of risk occurrence, the process conditions are fully considered, and the probability of different risks is determined for different processes. In each process, whether it is human operation, operation and control of equipment and facilities, addition of materials, implementation of process and control of environmental parameters, they are all independent events. Therefore, when quantifying the probability, for human risk, the ratio of the number of times the operation risk occurs to the total number of operations in a reasonable analysis cycle is used as the probability quantification of risk occurrence. For equipment and facilities, considering that the control of production by equipment and facilities in the process is continuous, the ratio of the duration of parameter risk occurrence to the total duration of parameter normal production is used as the indicator of probability quantification. For materials, the ratio of the duration of material parameter change risk to the duration of normal material parameter is used as the indicator of operation probability quantification. For process, the ratio of the duration of process parameter risk occurrence to the duration of normal process parameter occurrence is used as the indicator of probability quantification. For environment, the ratio of the duration of environmental parameter risk occurrence to the duration of normal environmental parameter occurrence is used as the indicator of probability quantification. Such probability determination can fit different types of parameter data and can also realize the embodiment of accurate probability quantification data of non-preset evaluation. Ensure the accuracy and rationality of risk probability determination and adaptability to different types of risks.

[0047] Extract different risk identification basic information from the risk identification information database, and conduct risk size analysis based on the process to form corresponding risk size information, including: for different processes, determine the corresponding average process operation time Enter the total number of items Total number of output materials Total number of monitoring parameters And the total amount of process materials v represents the number of different processes; according to the average process operation time corresponding to different processes Enter the total number of items Total number of output materials Total number of monitoring parameters And the total amount of process materials Determine the importance of different processes in the production process in: Get the average productivity of human impact of different human risk identification basic information in the process risk identification basic information set under the corresponding process Average cost rate of human impact Average cycle rate of human impact Average cost rate of human disposal And the average time rate of human treatment Combined with the process importance of the corresponding process Determine the risk amount corresponding to different human risks m is the number of the basic information for identifying different human risks under the process numbered v, where: Obtain the average productivity of the equipment and facilities that affect the risk identification basic information of different equipment and facilities in the process risk identification basic information set under the corresponding process Equipment and facilities affect the average cost rate Average cycle rate of equipment and facilities impact Average cost rate of equipment and facility disposal And the average time rate of equipment and facilities disposal Combined with the process importance of the corresponding process Determine the risk amount corresponding to different equipment and facility risks n is the number of the basic information for risk identification of different equipment and facilities under the process numbered v, where: Get the average productivity of materials that affect different material risk identification basic information in the process risk identification basic information set under the corresponding process Material impact average cost rate Average cycle rate of material impact Average cost rate of material disposal And the average material handling time Combined with the process importance of the corresponding process Determine the risk amount corresponding to different material risks i is the number of the basic information for risk identification of different materials under the process numbered v, where: Obtain the average productivity of the process impact of different process risk identification basic information in the process risk identification basic information set under the corresponding process Process affects average cost rate Process influences average cycle rate Average cost rate of process disposal And the average time rate of process treatment Combined with the process importance of the corresponding process Determine the risk amount corresponding to different process risks k is the number of the basic information for identifying different process risks under the process numbered v, where: Obtain the average productivity of environmental impact of different environmental risk identification basic information in the process risk identification basic information set under the corresponding process Average cost rate of environmental impact Average cycle rate of environmental impact Average cost rate of environmental disposal And the average time rate of environmental treatment Combined with the process importance of the corresponding process Determine the amount of risk corresponding to different environmental risks r is the number of the basic information for identifying different environmental risks under the process numbered v, where:

[0048] For the quantification of the risk impact, this application is based on the historical occurrence of risks, including output, cost, cycle, cost and cycle consumed by disposal, and the importance of different processes is evaluated. It should be noted that the quantification of the importance of the process is evaluated by the operation time, input material items, output material items, monitoring parameter quantity and total process material quantity of the process. After all, for chemical processes, the longer the time consumed, the more complex the reaction, the higher the stability of the reaction parameters that need to be guaranteed, the more material items required for the reaction, the more output material items, the more complex the reaction, the more complex the classification and extraction of the substances formed by the reaction, the more parameters monitored by the reaction, the higher the difficulty of maintaining the stability of the reaction, the more total reaction materials, the larger the volume of the reaction, and the more difficult the stability to be guaranteed by the reaction, so the importance is proportional to the change value of these parameters, which is very accurate and reasonable for quantifying the importance of the process. The output, cycle, cost, cost of disposal and cycle of disposal of the risk impact are also proportional to the size of the risk impact, so it is accurate and reasonable to evaluate the size of the risk based on these data.

[0049] According to the risk probability information and risk size information corresponding to different risk identification basic information, risk assessment is carried out and a risk level table is established, including: according to the process importance corresponding to different processes According to the importance of the process Establish process risk levels from large to small; Under different process risk levels, obtain the probability of occurrence of human risks corresponding to different human risks in the corresponding process and risk amount And form the process artificial grade value in, Under different process risk levels, obtain the probability of occurrence of human equipment and facility risks corresponding to different equipment and facility risks in the corresponding process and risk amount And form the process equipment and facility grade value in, Under different process risk levels, obtain the material risk occurrence probability corresponding to different material risks in the corresponding process and risk amount And form the process material grade value in, Under different process risk levels, obtain the process risk occurrence probability corresponding to different process risks in the corresponding process and risk amount And form the process level value in, Under different process risk levels, obtain the probability of occurrence of environmental risks corresponding to different environmental risks in the corresponding process and risk amount And form the process environment level value in, For different human risks in the process risk level, according to the corresponding process human level value Sort the processes from large to small, and assign human risk levels to the processes according to the rankings; for different equipment and facility risks in the process risk levels, assign the corresponding process equipment and facility level values Sort the process from large to small, and assign risk levels to the process equipment and facilities according to the ranking; for different material risks in the process risk level, assign risk levels according to the corresponding process material level values. Sort the process materials from large to small and assign risk levels to the process materials in turn according to the ranking; for different process risks in the process risk level, assign risk levels according to the corresponding process process level values. Sort the processes from large to small and assign process risk levels according to the ranking; for different environmental risks in the process risk level, assign a corresponding process environmental level value Sort the processes from large to small, and assign process environmental risk levels according to the ranking; combine the process human risk level, process equipment and facility risk level, process technology risk level and process environmental risk level under different process risk levels to form a risk level table.

[0050] It is understandable that the probability of risk occurrence and the magnitude of risk impact are two dimensions of risk assessment. Both often determine the attention paid by enterprises to different risks in production safety monitoring. Therefore, it is necessary to comprehensively consider both when determining the risk level. In addition, different risk types require different responses for production safety, and this response is also sequential. For example, human life and property are above all else, so when a person is at risk, the first thing to do is to get rid of the risk. Therefore, when conducting level assessment, it is also based on different types of risks in different processes. Different assessments are made. On the one hand, this is conducive to showing more risk types under the corresponding risk level, and on the other hand, it is also conducive to guiding enterprises to provide different types of risk attention when conducting production safety monitoring, better helping enterprises to allocate resources and control costs for risk monitoring, and making enterprise risk management more efficient.

[0051] S3: Obtain real-time risk information, and confirm the risk level in combination with the risk identification information database and risk level table to form risk level warning information.

[0052] Acquire real-time risk information, and confirm the risk level in combination with the risk identification information base and risk level table to form risk level warning information, including: for different process steps, obtain the real-time information of human behavior, real-time parameter information of equipment and facilities, real-time parameter information of materials, real-time parameter information of processes, and real-time parameter information of the environment in the corresponding process; confirm the risk according to the different types of real-time information corresponding to different processes, and combine the risk identification information base and risk level table to form the corresponding risk level warning information.

[0053] The purpose of establishing risk levels is, on the one hand, to provide enterprises with the focus of production safety monitoring and the reasonable arrangement of monitoring resources, and on the other hand, to identify different risks in advance. In risk monitoring, based on the focus of risk levels and using identification information as a reference for real-time data collection, risk monitoring and early warning can be achieved more accurately and efficiently.

[0054] According to the different types of real-time information corresponding to different processes, risks are confirmed in combination with the risk identification information library and risk level table to form corresponding risk level warning information, including: obtaining the real-time information of human behavior corresponding to the process, and matching it with the human risk identification feature information of the corresponding process. If there is a match between the real-time information of human behavior and the human risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output; obtaining the real-time parameter information of equipment and facilities corresponding to the process, and matching it with the equipment and facility risk identification feature information of the corresponding process. If there is a match between the real-time parameter information of equipment and facilities and the equipment and facility risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output; obtaining the real-time information of materials corresponding to the process Parameter information is obtained, and a matching comparison is made with the material risk identification feature information of the corresponding process. If the material real-time parameter information matches the material risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output; the process real-time parameter information corresponding to the process is obtained, and a matching comparison is made with the process risk identification feature information of the corresponding process. If the process real-time parameter information matches the process risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output; the environment real-time parameter information corresponding to the process is obtained, and a matching comparison is made with the environment risk identification feature information of the corresponding process. If the environment real-time parameter information matches the environment risk identification feature information, the corresponding level is determined, and the corresponding level value and risk type are output.

[0055] Of course, when conducting monitoring and early warning, for different types of risk information, only when it fully matches the identification information can it be determined that the risk may occur. The level table can be used to make reasonable resource arrangements and disposals based on the results of risk identification, making the company's production safety monitoring more reasonable and effective.

[0056] The present invention also provides a safety monitoring system for chemical production enterprises, which is configured to collect risk identification information, perform information normalization processing, and establish a risk identification information database; extract risk identification information in the risk identification information database, establish risk levels based on the risk matrix, and form a risk level table; obtain real-time risk information, and confirm the risk level in combination with the risk identification information database and the risk level table to form risk level warning information.

[0057] The system is configured to provide risk identification information collection to establish a risk identification information database, and implement risk level analysis based on the risk matrix based on the risk identification database, providing reasonable guidance and disposal equipment and facilities for real-time risk detection in chemical production, and providing a stable material basis for the reasonable and efficient realization of chemical production safety monitoring.

[0058] In summary, the chemical production enterprise safety monitoring method and system provided by the embodiments of the present invention have the following beneficial effects:

[0059] The method continuously collects relevant identification information after the occurrence of risks to distinguish different risk types in a standardized manner, establishes a risk identification information database for chemical production safety, and at the same time performs reasonable analysis and processing of relevant information on the risk identification information in the risk identification information database, and uses the risk matrix as a way of risk identification analysis to reasonably and accurately complete the level confirmation of many risks of different types. In this way, when conducting safety monitoring of chemical production, reasonable risk monitoring and disposal can be carried out according to the established risk level table. On the one hand, the established risk level table provides most of the risk points involved in chemical production safety, which is conducive to enterprises to establish reasonable disposal plans for these risk points in advance, and can quickly identify risks, making risk disposal more targeted and effective. On the other hand, it also guides enterprises to establish reasonable risk response policies according to different levels of risks in the process of chemical production. While fully ensuring reasonable control of risks, it can also avoid unreasonable economic and resource consumption caused by blind disposal due to inadequate risk identification, greatly optimizing the management cost of risk control in the chemical production process, and making the risk management of enterprises more efficient.

[0060] The system is configured to provide risk identification information collection to establish a risk identification information database, and implement risk level analysis based on the risk matrix based on the risk identification database, providing reasonable guidance and disposal equipment and facilities for real-time risk detection in chemical production, and providing a stable material basis for the reasonable and efficient realization of chemical production safety monitoring.
