Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

It should be noted that, all actions for acquiring signals, information or data in the present disclosure are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

Fig. 1 is a flow chart of a targeted security authentication method based on risk pre-control provided in an exemplary embodiment of the present disclosure. The method provided by the disclosure can be applied to targeted security authentication technology based on risk pre-control of enterprises in various fields, such as security authentication technology in the fields of thermal power plants, battery manufacturing and the like. For a clearer understanding of the present disclosure, an example of application to a thermal power plant will be exemplified below. It should be understood, however, that the illustration of a thermal power plant is not to be taken as a limitation on the field of application and the scope of protection of the present disclosure. As shown in fig. 1, the method may include S101 to S104.

S101, dividing the job tasks to obtain a plurality of job procedures.

By way of example, the job tasks of a power generation enterprise may refer broadly to production activities such as operation, overhaul, maintenance, inspection, testing, sampling, testing, engineering, etc., each job task may be divided into job procedures according to a process flow. Each working procedure has corresponding risks, the dangerous sources are gradually identified according to the working procedures, the possible accident types of each working procedure are clarified, and correspondingly formulated control measures can be more systematically and comprehensively realized.

In order to facilitate the subsequent bayesian network analysis, the task may first be divided into a number of work procedures, defining the work sites of the specific work procedures, and systems and areas associated with the work. According to different characteristics of operation, equipment overhaul and the like, the operation procedures are divided differently. Fig. 2 is a schematic diagram illustrating a division of working procedures according to an exemplary embodiment of the present disclosure, and as shown in fig. 2, the pre-job preparation may include working procedures such as security measure inspection, personnel preparation, equipment preparation, material preparation, and spare part preparation, and the post-job site cleaning stage may include working procedures such as security measure recovery, equipment self-condition and equipment environment condition confirmation, spare part consumption statistics, and defect handling conditions.

Taking the reheater service operation shown in fig. 3 as an example, the operation stage thereof may be divided into several operation steps. For example, preparation before overhaul, wear and explosion prevention inspection of the high-temperature reheater, inspection of a connecting pipe and a header hanging point, sampling of a reheater pipe, scaffold removal, and end of overhaul work, etc. can be included. Wherein, the preparation before maintenance can be further subdivided into: ① Entering the interior of a furnace top hot box for vibration coking; ② The outer wall of the tube of the heating surface of the low-temperature reheater and the high-temperature reheater is cleaned up of accumulated ash; ③ The high-order reheater area is erected with a scaffold. The high temperature reheater wear and explosion protection inspection can be further subdivided into: ① Checking the sparse clamp, the protective tile and the pipe clamp of the high-temperature reheater; ② Checking anti-wear protection tiles of the low-temperature reheater and the high-temperature reheater tube rows; ③ Repairing the abrasion-proof explosion-proof inspection defect of the reheater; ④ And checking the wear-resistant protection tile. Reheater tube sampling can be further subdivided into: ① Determining a sampling position; ② Checking a weld joint; ③ The pipe is assembled, and the welded junctions at the two ends are clamped by the pipe clamp, so that the pipe can be welded. The end of the service work can be further subdivided into: ① Counting tools and materials, and cleaning the site; ② Checking whether the scaffold, the temporary power supply and the illumination needed for overhauling the present place are dismantled and cleaned.

S102, analyzing the operation procedures by adopting a Bayesian network, and determining the risk probability and the sensitivity value of each operation procedure.

For example, a specific job task of the thermal power plant may be determined as a job task node; the job tasks are divided to obtain a plurality of job steps, and the job steps are determined as job step nodes. In this manner, a target Bayesian network can be constructed based on job task nodes, job process nodes, and associations between individual processes and tasks. The state of each node in the target bayesian network may be that a security problem has occurred or that no security problem has occurred.

The safety problem may be a specific cause of safety accidents in the working tasks and working procedures, and may be classified into five types of unsafe behavior of a person, personnel conditions, conditions of objects, environmental conditions and production work management from the "man-machine-ring-pipe" level. Wherein the personnel condition elements include three aspects of mental condition, physiological condition and skill condition; the personnel unsafe behavior elements comprise the elements of incorrect operation (regulation) execution, nonstandard self behavior (actions, postures, station standardability requirements), safety risks existing in the state conditions of the production site, incorrect wearing and wearing of individual protective equipment, incorrect emergency treatment and the like; the condition elements of the object comprise the integrity and work suitability of the design and selection of the equipment system, the perfect quality of equipment facilities, the safety state and measures of a production place before operation, the sudden abnormal unsafe factors in the production operation and the like; the environmental condition elements comprise physical environment, space environment, safety protection, operation interference factors and other aspects; the production job management elements comprise technical management, production organization management, pre-job preparation management, job process management, basic management, compliance management and other aspects.

In the Bayesian comprehensive risk assessment process, a Bayesian network analysis method can be adopted for each operation procedure to obtain the risk probability of safety problems of each operation procedure node, determine the operation procedure which is easy to cause problems, and perform sensitivity analysis on each operation procedure node to determine the operation procedure with high sensitivity.

S103, determining a security authentication point from the operation procedure according to the risk probability and the sensitivity level value, wherein the risk probability of the security authentication point is greater than a first risk threshold value, and/or the sensitivity level value is greater than a first sensitivity threshold value.

For example, the first risk threshold and the first sensitivity threshold may be preset based on actual requirements. Security authentication may refer to the supervision of production security. Therefore, the operation procedure which is easy to cause problems and the operation procedure with higher sensitivity can be determined as the safety authentication point, the necessity of determining the safety authentication point is ensured, the pertinence of operation supervision is improved, and the operation supervision efficiency is further improved.

S104, determining a target authentication scheme according to the security authentication point.

The target authentication scheme comprises a target authentication person, a target authentication mode and target authentication equipment.

For example, the target authentication person may determine based on a risk level of the security authentication point, the target authentication manner may be determined based on a hazard factor characteristic of the security authentication point, and the target authentication device may be determined based on the target authentication manner of the security authentication point.

Therefore, the risk pre-control established by taking the operation task as the guide can be realized in each operation procedure of specific operation, the operation procedure with high risk and high sensitivity is determined from a plurality of operation procedures and is determined as a safety authentication point, and then a targeted personalized authentication scheme is established aiming at the safety authentication point from three different dimensions of personnel, modes and equipment, so that blindness of production safety supervision is reduced, supervision efficiency of production operation is improved, and scientific safety management of refinement and systemization of the production task is realized.

In an alternative embodiment, in S102, the analysis of the working procedures using the bayesian network, determining the risk probability of each working procedure may include:

Determining a job task as a job task node, determining a job procedure as a job procedure node, and constructing a target Bayesian network;

correcting the prior probability of the job task node;

By way of example, the historical incident data may include thermal power plant overhaul incident cases and historical experience management data, from which a parameter learning matrix may be constructedThe specific formula is as follows:

Wherein, For the total amount of historical accident data,/>Is the total number of job process nodes and job task nodes. Parameter learning matrix/>, which can utilize a target Bayesian networkAnd learning is carried out, and the prior probability that each operation procedure node and each operation task node are likely to have safety problems is obtained. The prior probability of the problem occurring in the job task node can be corrected to obtain the posterior probability of each job process node, and for example, the posterior probability corresponding to each job process can be obtained by the following formula:

Wherein, Characterization at job task/>Under the condition of safety problem, the operation procedure/>Probability of occurrence of a security problem, i.e., posterior probability; /(I)Characterization of working procedure/>The prior probability of a security problem occurring; /(I)Characterization in working procedure/>Under the condition of safety problem, job task/>Probability of a security problem occurring.

Fig. 4 is a schematic diagram of a bayesian network before adjustment, that is, a schematic diagram representing prior probabilities of each node, according to an exemplary embodiment of the present disclosure, the probability of occurrence of a safety problem may be adjusted to be 100% for the reheater maintenance operation state in fig. 4, and the probabilities of the other nodes may be correspondingly changed accordingly, so as to obtain fig. 5, that is, a schematic diagram representing posterior probabilities of each node after adjustment. The difference values of the corresponding nodes in fig. 4 and fig. 5 can be compared, and the key node which is greatly affected by the safety problem of the overhaul operation of the reheater, namely the operation procedure which is easy to cause the problem, is determined, wherein the greater the difference value is, the more easy the safety problem is caused in the operation procedure. The operation procedure which is easy to cause problems is determined as a security authentication point.

Therefore, the risk probability can be updated in real time through the continuously updated historical accident data, so that the safety certification point is updated in real time, the necessity of determining the safety certification point is ensured, the blindness of production safety supervision is reduced, and the supervision efficiency of production operation is improved.

In an alternative embodiment, in S102, the analysis of the working procedures using the bayesian network to determine the sensitivity level value of each working procedure may include:

For example, a task node in the target bayesian network may be set as a target node, the sensitivity analysis function of the bayesian network is utilized to perform sensitivity analysis on the task, and according to the sensitivity degree value of each task node for the task node, a task with higher sensitivity to the security problem of the task is determined, and the task is determined as a security authentication point. For example, the reheater overhaul operation may be set as a target node, and the sensitivity analysis is performed on the target bayesian network, a result of the sensitivity analysis is shown in fig. 6, a Gr on the upper right side in a schematic block diagram of each node in the figure is used for representing the high and low of the sensitivity level value, the larger the value of r is, the lower of the sensitivity level value represented by the Gr is, the sensitivity level value represented by the G1 is higher than the sensitivity level value represented by the G2 in fig. 6, the sensitivity level value represented by the G2 is higher than the sensitivity level value represented by the G3, and the sensitivity level value represented by the G3 is higher than the sensitivity level value represented by the G4. Therefore, the high-sensitivity operation procedure can be determined as the safety authentication point, the necessity of determining the safety authentication point is ensured, the blindness of production safety supervision is reduced, and the supervision efficiency of production operation is improved.

In an alternative embodiment, the target authentication scheme includes a target authentication person, and in S104, determining the target authentication scheme according to the security authentication point may include:

In an alternative embodiment, determining the risk level of the security authentication point according to the risk probability and the sensitivity value may include:

if the risk probability and the sensitivity level value meet the first preset condition and do not meet the second preset condition, determining that the risk level is a high risk level;

if the risk probability and the sensitivity level value do not meet the first preset condition and the second preset condition, determining that the risk level is a middle risk level;

if the risk probability and the sensitivity level value do not meet the first preset condition and meet the second preset condition, the determined risk level is a low risk level.

In one embodiment, the first preset condition includes: the risk probability of the operation procedure is larger than a second risk threshold value, and/or the sensitivity degree value of the operation procedure is larger than a second sensitivity threshold value; the second preset condition includes: the risk probability of the working procedure is smaller than the third risk threshold value, and/or the sensitivity degree value of the working procedure is smaller than the third sensitivity threshold value.

The second risk threshold is greater than the third risk threshold, and the third risk threshold is greater than the first risk threshold; the second sensitivity threshold is greater than the third sensitivity threshold, which is greater than the first sensitivity threshold. The second risk threshold, the second sensitivity threshold, the third risk threshold, and the third sensitivity threshold may be preset based on actual requirements.

Based on the scheme, the operation procedures with higher sensitivity and high possibility of generating safety problems can be determined as safety authentication points, the risks of the safety authentication points can be classified into three grades of low, medium and high, for example, the risk grade of the operation procedure node with higher sensitivity value or higher risk probability can be determined as high risk grade, and for example, the risk grade of the operation procedure node with higher posterior probability, for example, the risk grade of the operation procedure node with the posterior probability of more than 60 percent, can be determined as high risk grade; the risk level of the working procedure node with the smaller sensitivity value or the smaller risk probability can be determined as a low risk level, and for example, the risk level of the working procedure node with the smaller posterior probability, for example, the risk level of the working procedure node with the posterior probability less than 30%, can be determined as a low risk level, and the risk levels corresponding to the other nodes are medium risk levels. The risk level of each operation procedure can be obtained through the bayesian network analysis result of the reheater maintenance operation, and the risk level can be shown in table 1:

TABLE 1

Different levels of security authentication points can be set according to different risk levels. If the risk level of the operation procedure is a low risk level, setting the security authentication point as a 1-level security authentication point; if the risk level of the operation procedure is the risk level of the stroke, setting the security authentication point as a 2-level security authentication point; if the risk level of the operation procedure is a high risk level, the security authentication point can be set to be a 3-level security authentication point. Specifically, it can be shown in table 2:

TABLE 2

In an alternative embodiment, determining the target authentication person according to the risk level of the security authentication point may include:

Illustratively, the provers may be classified into different levels, such as different levels of manager in a factory leader, department, team, etc. The correspondence between the risk level and the certifying person may be pre-calibrated and stored.

Aiming at low risk level operation procedures, such as connection pipe and header hanging point inspection in reheater maintenance, a 1-level safety authentication point is set, and a first-level acceptance check can be adopted. Before the working procedure is executed, a working responsible person needs to check the execution condition of risk pre-control management safety measures of the working procedure on site before the working procedure is started, and signs and confirms on the premise of meeting the working standard.

Aiming at the working procedures of medium risk level, such as entering the furnace top box for coke vibration and the like in the overhaul of a reheater, a 2-level safety identification point is set, and a second-level acceptance check can be adopted. Two levels of personnel signing are required before this procedure is performed. The working responsible person, each production department spot check (special worker) and the above personnel check the risk pre-control management safety measure execution condition of the working procedure on site before the working procedure starts, and respectively sign and confirm on the premise of meeting the working standard.

Aiming at high risk level operation procedures, such as checking anti-abrasion protection tiles and the like in reheater overhaul, a 3-level safety certification point is set, and three-level acceptance is adopted. Three levels of signatures are required before this procedure is performed. The working person in charge, each production department spot check (special worker) and above, the production technical department or An Jian ring monitoring department person in charge and above need to check the risk pre-control management safety measure execution condition of the high risk level working procedure on site before working the high risk level working procedure, and respectively sign and confirm on the premise of meeting the operation standard.

Therefore, according to the corresponding relation between the predetermined risk level and the certification personnel, the target certification personnel corresponding to the current risk level can be rapidly determined, the waste of manpower is avoided, the flexibility of production operation supervision is improved, and the problem that supervision is not in place is avoided.

In an alternative embodiment, the target authentication scheme includes a target authentication mode, and in S104, determining the target authentication scheme according to the security authentication point may include:

and determining a target authentication mode according to the hazard factor characteristics of the security authentication point.

The hazard factor characteristics of the working procedure may include: action characteristics and production phase. As shown in fig. 7, the action characteristics include hard-related characteristics and soft-related characteristics related to the effect aging, and trace-back characteristics and trace-free characteristics related to the trace-back angle, and the production phase includes a production preparation phase, a production phase, and a production end phase. The safety authentication point is a selected operation procedure, namely the hazard factor characteristic of the safety authentication point can refer to the hazard factor characteristic of the corresponding operation procedure.

Hazard factors can be classified into hard and soft associations from the time-efficiency perspective of the effect, and some hazard factors directly cause serious accident effects, which are called hard association hazard factors, such as sparks capable of igniting combustible gases, causing fires or explosions, and the supervision of such hazard factors is strictly prevented. Some hazard factors cannot immediately cause accident consequences, but can continuously influence safe production, have time persistence, and finally cause accident conditions to be influenced by other factors, namely soft-association hazard factors, such as equipment leakage can not obviously influence production or cause accidents, but can influence the health state of equipment or cause fire due to leakage, high-concentration gas can cause gas explosion and the like under the condition of sparks, so that the supervision of the hazard factors is controlled on one hand, and on the other hand, the hazard factors are treated and eliminated immediately after the occurrence.

Hazard factors can be classified into trace and no trace from the traceability point of view of action, some hazard factors can not leave trace, and the hazard factors belong to no trace, and the state of the hazard factors can only be found in the occurring process, typically, unsafe behaviors of people in most cases can only be monitored in the production operation process. Some harmful factors can leave marks, can be found after the post-production, can be detected after the production operation is stopped, and can be detected only after the shutdown, and the timeliness related to the results can be combined.

Hazard factors are divided from the process of production and can be divided into a production preparation stage, a production stage and a production ending stage. The hazard factors are generated in the production preparation stage, some are generated in the production process, and other are generated in the production ending stage, so that hidden danger is left for subsequent work.

The hazard factors have various action characteristics, and the target identification mode can be determined by specifically analyzing the action characteristics of various hazard factors. In one embodiment, the target authentication may be determined by:

Aiming at the hazard factors generated in the production preparation stage, determining a target authentication mode as to execute a corresponding operation procedure after the authentication of a target authentication person, wherein the target authentication mode can be represented by H;

aiming at the hazard factors with the action characteristics of hard association characteristics or traceless characteristics, determining a target authentication mode as a corresponding operation procedure of the target authentication personnel in a full-range continuous monitoring mode, wherein W can be used for representing the target authentication mode;

Aiming at the hazard factors with the action characteristics of soft association characteristics or trace characteristics, the target authentication mode is determined to be the target authentication mode, and the target authentication mode can be represented by S without monitoring corresponding operation procedures.

Therefore, according to the hazard factor characteristics, the target authentication mode which is adaptive to the safety authentication point and flexible and effective can be determined, the blindness of production safety supervision is reduced, and the supervision efficiency of production operation is improved.

In addition, the target authentication mode can be further supplemented by combining the production operation state during supervision and authentication, the required checking frequency and the position of the authentication personnel.

For example, the production job status at the time of supervision and authentication may refer to a supervision check or a shutdown supervision check during the production job. Aiming at the authentication mode of continuously monitoring the corresponding operation procedure in the whole process of the target authentication personnel, the supervision and inspection in the production process can be determined; the target certification personnel can determine to carry out supervision and inspection after the production is finished, namely, the shutdown without monitoring the corresponding operation.

For example, the required inspection frequency may be determined according to a risk level of the work process, the higher the risk level, the higher the required inspection frequency. The required inspection frequency may be determined from the hazard factor characteristics, in particular, for hazard factors whose action characteristics are hard-associated characteristics or traceless characteristics, the required inspection frequency may be determined to be always under supervision on site; the required inspection frequency may be determined as a periodic spot inspection for a hazard factor whose action characteristic is a soft-related characteristic or a mark characteristic, or a hazard factor generated at a production preparation stage.

For example, the location of the authentication personnel may be determined based on available authentication equipment and complexity of field operations, i.e., determining whether the supervising authentication personnel is performing field authentication or remote authentication. Or may be determined by the authenticating person itself.

Still, the operation of repairing the reheater is taken as an example, wherein the target authentication mode corresponding to each operation procedure can be as shown in table 3:

TABLE 3 Table 3

In an alternative embodiment, the target authentication scheme further includes a target authentication device, and in S104, determining the target authentication scheme according to the security authentication point may include:

and determining target authentication equipment according to the security authentication point.

For example, besides field visual inspection, related equipment can be used as a verification means, and different target verification equipment can be selected according to specific screened operation procedures, namely safety verification points, so as to form a verification means scheme of the system. Therefore, the safety authentication can be flexibly and scientifically realized, and the supervision efficiency of production operation is improved. The selection of the authentication means may take into account the risk characteristics of each working procedure, and may specifically include:

(1) The visual perception equipment means adopted for the remote authentication working procedure of the authentication personnel can comprise a remote monitoring system, an unmanned aerial vehicle, a robot and a personnel positioning system.
