[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Figure 1 is a flow chart of the steps of a risk management method provided by an embodiment of the present invention, such as Figure 1 As shown, the method may include:

[0046] Step 101: Based on target device data collected for a target object, determine a target risk type and a target risk level corresponding to the target object.

[0047] In an embodiment of the present invention, data acquisition equipment is deployed for a target object, wherein the target object may be a gas pipeline, a gas equipment, a gas station, an environment, etc., and the data acquisition equipment may include an Internet of Things device, such as a gas detection device, a pressure detection device, an image acquisition device, etc. Correspondingly, the target device data may include Internet of Things device data and system record data, such as pressure data, gas concentration data, image data, etc. The target device data collected by the data acquisition device for the target object is obtained, and based on the target device data, the target risk category and target risk level corresponding to the target object are determined. Among them, the target risk type includes a hidden danger type and an accident type, and the target risk level can be defined according to the severity of the risk and the scope of impact. For example, the target risk level can be divided into high risk, medium risk and low risk.

[0048] Exemplarily, judgment conditions corresponding to different risk types can be set in advance for different types of equipment data, for example, first judgment conditions and second judgment conditions corresponding to different risk types can be set for different types of equipment data. For any target equipment data, when the value of the target equipment data satisfies the first judgment condition or the second judgment condition corresponding to the equipment data of this type, the target risk type can be determined to be the risk type corresponding to the first judgment condition or the second judgment condition. For example, for pressure data, assuming that the judgment condition is set to be when the pressure data is greater than a and less than b, the target risk type is determined to be a hidden danger type; when the judgment condition is when the pressure data is greater than b, the target risk type is determined to be an accident type. For image data, assuming that the judgment condition is set to be when a general violation operation is detected in the image data based on image recognition, the target risk type is determined to be a hidden danger type; when the judgment condition is when a major violation operation is detected in the image data based on image recognition, the target risk type is determined to be an accident type.

[0049] Step 102: determine a target event tree matching the target risk type in the risk disposal bowtie diagram corresponding to the control items satisfied by the target object, and determine a first disposal method in the target event tree based on the target risk level; different risk types correspond to different event trees.

[0050] In an embodiment of the present invention, the bow-tie theory is combined with the dual pre-control method to construct a risk management bowtie diagram (bow-tie model) for the field of gas safety. The dual pre-control principle for gas safety issues mainly refers to the dual prevention mechanism of safety risk classification management and hidden danger investigation and treatment. This principle aims to control safety risks before hidden dangers are formed through a systematic method, and through hidden danger investigation, timely identify possible deficiencies and loopholes in the risk control process, and eliminate hidden dangers in a timely manner, thereby ensuring the safety of gas use. The core "risk-hidden danger-accident" management and control chain of the dual pre-control principle is based on the basic form of the bow-tie theory. The left and right branches in the risk management bowtie diagram are regarded as two different event trees. The event tree can be a hidden danger control tree on the left branch and an accident handling tree on the right branch. Different risk types are matched with different event trees, among which the hidden danger control tree matches the hidden danger type, and the accident handling tree matches the accident type. As Figure 2As shown, the hidden danger management tree can include risk hidden dangers and corresponding treatment methods for different risk levels. Specifically, risks can be regarded as hidden dangers with lower risk levels, that is, the hidden dangers far from the center in the hidden danger management tree are the treatment methods corresponding to the hidden dangers with lower risk levels (i.e., the risks in the double prevention and control principle), and the hidden dangers close to the center are the treatment methods corresponding to the hidden dangers with higher risk levels, such as rectification measures; the closer to the middle, the higher the risk level and the higher the possibility that the risk hidden danger will cause an accident. The accident handling tree can include accidents and corresponding treatment measures for accidents of different risk levels. The closer to the center, the treatment methods corresponding to major accidents, and the farther away from the center, the treatment methods corresponding to secondary accidents.

[0051] According to different target objects, they are defined as control items, where control items can be defined according to the object type of the target object. For each control item, a risk disposal bowtie diagram corresponding to the control item is constructed. Exemplarily, for each control item, the corresponding business definition judgment rule can be defined; and based on the rule, the corresponding IoT and system data are matched. The risk type in the left and right branches and the corresponding relationship between the risk level and the disposal method are divided and set by the collected device data.

[0052] After determining the target object, determine the control items that the target object satisfies based on the target object, and obtain the risk treatment bowtie diagram corresponding to the control items. Based on the risk treatment bowtie diagram, determine the target event tree corresponding to the target risk type, that is, determine the target event tree based on the target risk type. Since the target event tree defines treatment methods corresponding to different risk levels, based on the target risk level, the treatment method corresponding to the target risk level can be determined in the target event tree as the first treatment method.

[0053] Optionally, step 102 may include the following steps:

[0054] Step 201: Based on the target risk level, determine a handling method corresponding to the target risk level in the target event tree.

[0055] Step 202: Determine the disposal method as the first disposal method.

[0056] In the embodiment of the present invention, based on the target risk level, a handling method corresponding to the target risk level is determined in the target event tree.

[0057] For example, Figure 3As shown in the figure, assuming that the control item is a pipe network leak, the risk disposal bow tie diagram corresponding to the control item includes multiple disposal methods, namely: leakage IoT monitoring disposal method corresponding to low risk level, that is, when the risk level is low, it means that the target object has risk hazards, but the severity is low, and the IoT data can be monitored in real time first; pipe network inspection disposal method corresponding to medium risk level, that is, when the risk level is medium, it means that the target object has risk hazards, and the severity is medium, and the pipe network can be inspected and checked to find out the possible deficiencies and loopholes in the risk control process; regulator maintenance disposal method corresponding to higher risk level, that is, when the risk level is high, it is necessary to directly repair the risk hazard point, that is, the regulator, to eliminate the risk hazard as soon as possible; pipeline maintenance disposal method corresponding to high risk level, that is, when the risk level is high, it is necessary to comprehensively check the safety hazards existing in gas facilities, workplaces, etc., to eliminate the risk hazards as soon as possible and eliminate the hidden dangers existing in the pipe network. Assuming that the target risk level is medium risk level, the disposal method corresponding to the medium risk level, that is, the pipe network inspection disposal method, is determined as the first disposal method.

[0058] In a possible implementation, algorithm models can be established based on the hidden danger control tree and the accident handling tree in the risk handling bow tie diagram, respectively, so that the algorithm model can quickly identify the corresponding handling method based on the target equipment data.

[0059] In an embodiment of the present invention, by determining corresponding disposal methods based on different risk levels, appropriate management and control measures can be taken in a timely manner to effectively reduce the possibility of these risks occurring. At the same time, it can help ensure that resources (such as time, money, and manpower) are used in the most effective way to avoid excessive processing of security risks at low risk levels or insufficient resources for processing security risks at high risk levels.

[0060] Step 103: Obtain the execution effect of the first disposal method, and if the execution effect does not meet the preset execution effect, execute the second disposal method corresponding to the next level of the target risk level in the target event tree for the target object, until the execution effect obtained for the target object meets the preset execution effect.

[0061] In an embodiment of the present invention, a first disposal method is executed on a target object, and an execution effect of the first disposal method is obtained. The execution effect may be obtained based on feedback from disposal personnel, and the disposal effect may include effective disposal and invalid disposal. Effective disposal is used to characterize that after the first disposal method is executed on the target object, the hidden danger corresponding to the target object has been eliminated or the accident has been resolved; invalid disposal is used to characterize that after the first disposal method is executed on the target object, the hidden danger corresponding to the target object has not been eliminated or the accident has not been resolved. When the execution effect corresponding to the first disposal method does not meet the preset execution effect, it is characterized that the execution effect of the first disposal method has not met expectations. The preset execution effect may be effective disposal. If the execution effect corresponding to the first disposal method is invalid disposal, the second disposal method corresponding to the next level of the target risk level may be determined in the target event tree. Since the event tree includes disposal methods corresponding to different risk levels, the disposal intensity and disposal effect of the disposal method are proportional to the risk level. Therefore, when the first disposal method corresponding to the target risk level cannot achieve the expected execution effect, the disposal method corresponding to the next level can be determined as the second disposal method, and the second disposal method is executed on the target object to obtain the execution effect corresponding to the second disposal method, and it is determined whether the execution effect corresponding to the second disposal method meets the preset execution effect. This is repeated until the execution effect obtained for the target object meets the preset execution effect.

[0062] In one possible implementation, when the target event tree is a hidden danger management and control tree, if the execution effect corresponding to the handling method corresponding to the highest risk level in the hidden danger management and control tree still does not meet the preset execution effect, the target object can be handled based on the handling method corresponding to the lowest risk level in the accident handling tree. If the execution effect of the handling method corresponding to the lowest risk level in the accident handling tree still does not meet the preset execution effect, the handling method corresponding to the next level of the lowest risk level in the accident handling tree is executed for the target object until the execution effect obtained for the target object meets the preset execution effect.

[0063] In summary, in an embodiment of the present invention, based on the target device data collected for the target object, the target risk type and target risk level corresponding to the target object are determined; a target event tree matching the target risk type is determined in the risk disposal bowtie diagram corresponding to the control items satisfied by the target object, and a first disposal method is determined in the target event tree based on the target risk level; the execution effect of the first disposal method is obtained, and when the execution effect does not meet the preset execution effect, the second disposal method corresponding to the next level of the target risk level in the target event tree is executed for the target object, until the execution effect obtained for the target object meets the preset execution effect. In this way, due to the complexity and diversity of the gas system, as well as the specific risk differences in different regions and environments, the embodiment of the present invention can more comprehensively and deeply identify and analyze these different risks and their interrelationships by defining different event trees for different risk types in the risk disposal bowtie diagram, and then determining the first disposal method matching the target risk level in the target event tree based on the target risk level. Furthermore, the embodiment of the present invention can effectively guide the implementation of specific risk prevention and control measures by combining the bow-tie theory with the method of the double pre-control principle, and then quickly and accurately determine the first disposal method based on the risk disposal bow tie diagram when the target object has a safety risk, thereby improving the accuracy and reliability of risk assessment. Then, by judging the execution effect of the disposal method, a reliable disposal method that can eliminate the safety risk is continuously searched, ensuring that the safety risk generated by the target object can be effectively resolved, and improving the reliability of safety risk disposal.

[0064] Optionally, the embodiment of the present invention may further include the following steps:

[0065] Step 301: Based on the feedback of the execution effect of each treatment method, the risk treatment bowtie chart corresponding to each control item is regularly reviewed and updated.

[0066] In an embodiment of the present invention, the execution effect of each disposal method after execution is obtained, and the risk disposal bowtie diagram corresponding to each control item is regularly reviewed and updated based on the execution effect. Exemplarily, when the execution effect of a disposal method is that the disposal is effective, the disposal method can be used as a reference content for updating the disposal methods corresponding to other control items; when the execution effect of a disposal method is that the disposal is invalid, the content of the disposal method is updated to improve the disposal effect. At the same time, as the system develops and changes, the original risk factors and disposal methods may need to be updated. This means that the risk disposal bowtie diagram is not static and needs to be regularly reviewed, adjusted, and updated to maintain its effectiveness and relevance.

[0067] Optionally, the embodiment of the present invention further includes the following steps:

[0068] Step 401: Define multiple control items for the field of gas safety.

[0069] In the embodiment of the present invention, different control items are defined for the field of gas safety according to different risk types, wherein the control items may include pipe network leakage, equipment failure, and the like.

[0070] Step 402: For any of the control items, obtain a historical disposal solution corresponding to the control item and historical equipment data corresponding to the historical disposal solution.

[0071] In an embodiment of the present invention, for any control item, based on the historical disposal situation corresponding to the control item, a historical disposal plan is obtained, that is, the disposal plan used for the historical disposal of the target object corresponding to the control item, and the historical equipment data corresponding to the historical disposal plan, that is, the data situation of the historical equipment data collected by the equipment when performing risk disposal on the target object corresponding to the control item.

[0072] Step 403: Based on the historical handling solutions and the historical equipment data, determine multiple hidden danger handling methods and multiple accident handling methods for the control item.

[0073] In an embodiment of the present invention, historical equipment data and historical disposal plans are analyzed based on multiple groups of historical equipment data and historical disposal plans, the correlation between changes in equipment data and the selection of disposal plans is obtained, and the historical disposal plans are classified to divide multiple hidden danger disposal methods and multiple accident disposal methods.

[0074] At the same time, based on historical equipment data and national standards, industry standards, enterprise standards and other specifications and standards related to gas safety, corresponding risk levels are set for different hidden danger handling methods and accident handling methods.

[0075] Step 404: construct a hidden danger management and control tree based on the multiple hidden danger handling methods, and construct the accident handling tree based on the multiple accident handling methods; the accident handling tree and the hidden danger management and control tree are used to construct the risk handling bowtie diagram.

[0076] In an embodiment of the present invention, a hidden danger management and control tree is constructed based on multiple hidden danger handling methods. Exemplarily, the risk levels corresponding to multiple hidden danger handling methods can be determined, and a hidden danger management and control tree is constructed based on the hidden danger handling methods corresponding to different risk levels. An accident handling tree is constructed based on multiple accident handling methods. Exemplarily, the risk levels corresponding to multiple accident handling methods can be determined, and an accident handling tree is constructed based on the accident handling methods corresponding to different risk levels. The risk levels corresponding to different handling methods can be set according to the handling content, handling scope, handling intensity, and handling effect of the handling method, and the specific embodiment of the present invention does not limit this.

[0077] The accident handling tree and the hidden danger control tree are used to construct a risk handling bowtie diagram. Specifically, the accident handling tree and the hidden danger control tree can be connected to obtain a risk handling bowtie diagram, such as Figure 2 shown.

[0078] The embodiment of the present invention constructs a risk management bowtie diagram including a hidden danger management tree and an accident handling tree. The hidden danger management tree indicates that the target object has not had a substantial accident yet, but needs daily risk management, which is a preventive measure; the accident handling tree indicates that an accident has already occurred and that timely emergency handling of the accident is required, which is a remedial measure. The personnel skills, economic investment, measures taken, etc. corresponding to the handling methods in the hidden danger management tree and the accident handling tree will be differentiated due to the different preventive measures or remedial measures taken and the different risk levels. In the scenario of the actual application of the risk management bowtie diagram, by combining algorithms or management methods, the target object can be monitored in real time, and when the target object has risk hazards, the handling method can be determined in time for management and control, so that the hidden danger control can be gradually realized from planning to predictive, and then through the management of risk hazards, the probability of accidents can be reduced, and the effect of cost management can be achieved to a certain extent.

[0079] Exemplarily, when the target object is a voltage regulator, data collection and data recording are performed on the voltage regulator in real time to monitor the voltage regulator in real time. For example, the inlet and outlet pressure values ​​of the voltage regulator can be monitored daily. Assuming that when the inlet and outlet pressure values ​​are abnormal, the target device data corresponding to the voltage regulator is analyzed to determine whether the hidden danger control tree on the left branch of the corresponding risk disposal bow tie diagram or the accident disposal tree on the right branch is needed, so as to determine whether hidden danger control or accident disposal is needed, obtain the disposal method corresponding to the risk level, and perform risk disposal on the voltage regulator based on the disposal method.

[0083] The first acquisition module 503 is used to obtain the execution effect of the first disposal method, and if the execution effect does not meet the preset execution effect, execute the second disposal method corresponding to the next level of the target risk level in the target event tree for the target object, until the execution effect obtained for the target object meets the preset execution effect.
