[0063] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0064] Example 1

[0065] This embodiment provides a method and system for assessing the security risk level of key areas. Figure 1 As shown, including:

[0066] Step 1: Acquire several risk data of key areas, and establish risk trigger information corresponding to each key area according to the risk type corresponding to each risk data;

[0067] Step 2: Using the risk trigger information, perform risk assessment on the regional facility information of the corresponding key areas to obtain several potential risk accidents corresponding to each of the key areas;

[0068] Step 3: construct a facility risk model corresponding to each of the key areas, and determine the potential occurrence level and potential risk factor corresponding to each of the potential risk accidents at the current moment in the facility risk model;

[0069] Step 4: When the potential occurrence level is higher than the specified occurrence level, the dangerous impact area corresponding to the potential risk factor is located in the key area, and a danger warning list is generated and displayed.

[0070] In this example, the key areas may be: residential areas, schools, gas stations, construction, commercial office buildings, public facilities, hazardous chemicals and industrial and mining enterprises, hotels and tourism, and road traffic;

[0071] In this example, since different key areas have different constituent facilities, their corresponding regional facility information is also different;

[0072] In this example, the risk type represents a means for distinguishing the risks that may occur in different key areas, and different key areas may correspond to several different types of risk types;

[0073] In this example, potential risk accidents refer to risk accidents that may occur in key areas;

[0074] In this example, the potential occurrence level indicates the level of risk if a risk accident occurs. Generally speaking, there are five levels, namely:

[0075] 1. Major risk (red risk): This level of risk has the highest severity, usually involves multiple risk factors, and is difficult to control. If an accident occurs, it may cause huge economic losses or heavy casualties;

[0076] 2. Greater risk (orange risk): This level of risk is also of high severity, involves more dangerous factors, and is more difficult to control. If an accident occurs, it may cause major economic losses or serious casualties;

[0077] 3. General risk (yellow risk): This level of risk is within the controllable range. Although it may cause certain economic losses or injury accidents, it usually does not cause serious consequences.

[0078] 4. Low risk (blue risk): This level of risk has the lowest severity and is usually under control. Even if an accident occurs, it will only cause general economic losses or minor injuries.

[0079] 5. No risk (green risk): This level of risk is not dangerous and is usually stable, that is, no accidents will occur. The worst case scenario is that the only non-injury accident can be solved by individuals themselves.

[0080] In this example, the potential risk factor indicates the cause of the risk incident. For example, if a pedestrian leaves a burning cigarette butt and encounters a suitable wind force, it may cause a fire. Then the burning cigarette butt and the corresponding wind force constitute the potential risk factor of the fire.

[0081] In this example, the occurrence levels are specified as: general risk and above, namely: general risk, relatively large risk and major risk;

[0082] In this example, the hazardous impact area refers to the area where potential hazardous factors have an impact on the key area;

[0083] In this example, the danger warning list lists all potential risks in key areas and issues corresponding warnings for potential risks with high danger levels.

[0084] The working principle and beneficial effects of the above technical solution: Since different key areas have different properties and different facility displays, before conducting a safety risk assessment, it is necessary to establish risk trigger information for key areas based on the risk data of key areas, and then conduct a risk assessment on the facilities in the key areas, determine the potential risk accidents contained in the key areas, and then build a model to analyze the level and cause of the risk at the current moment. Finally, conduct an in-depth analysis of potential risks at high risk levels, determine the scope of their hazardous impact, and generate a hazardous warning list in a timely manner to issue corresponding warnings. In this way, targeted safety analysis can be conducted on different types of key areas, reducing the occurrence of accidents and avoiding people’s property losses. In addition, during the assessment process, the safety level of each facility can be continuously monitored for a long time to analyze its stability, helping managers to make corresponding decisions.

[0085] Example 2

[0086] On the basis of Example 1, the method for assessing the security risk level of a key area, step 1, comprises:

[0087] Step 11: obtaining current facility data and historical construction data of the key area, using the historical construction data to build a conceptual model of the key area, and obtaining the construction causal relationship between the current facility data and the historical construction data in the conceptual model;

[0088] Step 12: Determine a number of risk items corresponding to the key area according to the regional attributes of the key area, determine the impact scope of each risk item in the conceptual model based on the item characteristics corresponding to each risk item, use the construction causal relationship to trace the data of each risk item, obtain the sub-current facility data and sub-historical construction data corresponding to each risk item, and establish the risk data corresponding to each risk item in combination with the corresponding impact scope;

[0089] Step 13: Determine the risk identification rules corresponding to the risk items based on the risk types corresponding to each of the risk data, split and identify the corresponding risk data using the risk identification rules, obtain a number of risk guiding factors corresponding to each of the risk items, input each of the risk triggering factors into the conceptual model for factor triggering training, and determine the sudden probability corresponding to each of the risk triggering factors in the key area;

[0090] Step 14: Count the target risk trigger factors whose sudden probability is not 0 corresponding to each of the risk items, identify the level of each of the target risk trigger factors respectively, and obtain the risk level classification corresponding to each of the risk items, and generate the risk trigger information corresponding to each of the risk items according to the risk items in the key areas and the target risk trigger factors and risk level classification corresponding to each of the risk items.

[0091] In this example, the current facility data represents the data on various facilities currently presented in the key area;

[0092] In this example, historical construction data refers to data generated during the construction process of key areas;

[0093] In this example, the conceptual model represents a model that can be used to simulate various facilities in the key area;

[0094] In this example, the construction causal relationship indicates the causal relationship between the current facility data and the historical construction data. For example, if the historical construction data contains highway maintenance data and the current facility data contains highway leveling data, then there is a construction causal relationship between the highway maintenance data and the highway leveling data.

[0095] In this example, the regional attributes represent the external attributes of the key areas, including: residential area attributes, school attributes, gas station attributes, construction attributes, commercial office building attributes, public facilities attributes, hazardous chemicals and industrial and mining enterprise attributes, hotel tourism attributes, and road traffic attributes;

[0096] In this example, risk items refer to items that may cause safety risks in key areas, such as fire, collapse, soil erosion, explosion, and leakage, etc.

[0097] In this example, the sub-current facility data represents data related to a risk item in the current facility data;

[0098] In this example, the sub-historical construction data represents data related to a risk item in the historical construction data;

[0099] In this example, the impact scope indicates the scope of impact of a risk item on the key area;

[0100] In this example, risk data refers to data used to describe a risk item;

[0101] In this example, the risk identification rules represent rules used to identify various risk factors included in risk items;

[0102] In this example, split identification refers to the process of splitting risk data into multiple sub-data and then identifying the risk guiding factors described by each sub-data;

[0103] In this example, factor trigger training refers to the process of training risk trigger factors in the conceptual model to determine the probability of key areas triggering each risk trigger factor;

[0104] In this example, the target risk trigger factor represents an unstable risk trigger factor that is easily triggered;

[0105] In this example, the risk level classification standard is 5 levels.

[0106] The working principle and beneficial effects of the above technical solution: In order to cope with different types of key areas, it is necessary to conduct a unified analysis for different key areas. First, the current facility data and historical construction data of the key areas are obtained. The risk items in the key areas are separated by establishing a conceptual model and analyzing the construction causal relationship between the current facility data and the historical construction data. The impact scope corresponding to each risk item and the various types of sub-data corresponding to each risk item are determined, thereby determining the risk data corresponding to each risk item. Then, the risk guidance factor of each risk item is determined according to the risk type of the risk data. The risk guidance factor is trained using the conceptual model to determine the sudden probability of each risk trigger factor in the key area. The target risk trigger factor with a high sudden probability is graded to determine the risk level classification of the risk item. Finally, all the information obtained is sorted out to create risk trigger information for each risk item. In this way, various risk data in the key areas can be summarized and listed, and all large and small risks in the key areas can be counted, providing strong reference materials for management personnel.

[0107] Example 3

[0108] Based on Example 2, the security risk level assessment method for key areas further includes:

[0109] The risk level corresponding to each of the target risk trigger factors is determined according to the level identification result, and the level trigger rules corresponding to each of the risk items in the key area are established and displayed.

[0110] The working principle and beneficial effects of the above technical solution: Create level trigger rules for each risk item to facilitate managers to understand the risk situation in key areas in a timely manner.

[0111] Example 4

[0112] Based on Example 1, the security risk level assessment method for key areas is characterized in that step 2 comprises:

[0113] Step 21: Acquire regional facility information of the key area, pre-process the regional facility information, generate a risk training information set and a risk test information set of the key area, perform risk assessment on the risk test information set using the risk trigger information, and obtain a number of assessment trigger factors contained in the key area;

[0114] Step 22: searching the risk level classification corresponding to each of the assessment trigger factors in the risk trigger information, performing trigger training on the assessment trigger factors using the risk training information, obtaining a risk trigger value corresponding to each of the assessment trigger factors, and mapping the risk trigger value to the corresponding risk level classification to obtain a trigger risk level corresponding to each of the assessment trigger factors;

[0115] Step 23: Determine the risk item corresponding to each of the risk trigger factors according to the risk trigger information, establish a facility distribution map of the key area according to the regional facility information, locate the target area facility corresponding to each of the risk items in the facility distribution map, configure corresponding risk item characteristics for each of the target area facilities, and determine the risk impact characteristics between facilities in different areas based on the trigger risk level corresponding to each of the assessment trigger factors;

[0116] Step 24: Establish several types of risk impact data corresponding to the regional facilities according to the risk item characteristics and risk impact characteristics corresponding to each of the regional facilities, determine the work interference characteristics of the risk impact data on the corresponding regional facilities, and generate several potential risk accidents in the key areas.

[0117] In this example, the risk training information set refers to an information set that determines the risk levels of various risks through training;

[0118] In this example, the risk test information set represents an information set used to test risks in a key area;

[0119] In this example, the facility distribution map refers to a map used to depict the distribution of various types of facilities in a key area;

[0120] In this example, the risk event characteristics represent the characteristics presented by the target area facilities when a risk event occurs;

[0121] In this example, the risk impact feature indicates that a regional facility is affected by other regional facilities due to the support or restriction relationship between the regional facilities;

[0122] In this example, one risk item can correspond to one or more target area facilities;

[0123] In this example, the work interference feature represents the interference of risk impact data on regional facilities.

[0124] The working principle and beneficial effects of the above technical solution are as follows: In order to further determine the potential risks existing in the key areas, a risk training information set and a risk test information set are first formulated based on the regional facility information of the key areas, and then these two information sets are used to perform risk assessment to determine the assessment trigger factors contained in the key areas and the trigger risk level corresponding to each assessment trigger factor, thereby determining the risk items contained in the key areas, and locating the target regional facilities involved in each risk item in the facility distribution map of the key areas, and analyzing the risk impact between facilities in different areas to create risk impact data for each regional facility, and finally generating potential risk accidents in the key areas by analyzing the interference of the risk impact data on the regional facilities. In this way, various types of potential risk accidents contained in the key areas can be quickly located, and potential risk accidents in the key areas can also be located. If an accident occurs, corresponding rescue can be carried out in a timely manner, and early intervention can also be carried out before the accident occurs.

[0125] Example 5

[0126] On the basis of Example 4, the method for assessing the security risk level of a key area, the process of preprocessing the regional facility information includes:

[0127] Cleaning the regional facility information, and determining facility parameters corresponding to each regional facility in the key area according to the cleaned regional facility information;

[0128] Establishing a recoding rule according to the coding form corresponding to each of the facility parameters, encoding the facility parameters using the recoding rule to obtain the standard parameters corresponding to each of the regional facilities;

[0129] Mirroring each of the standard parameters respectively to obtain non-standard parameters corresponding to each of the regional facilities, and constructing a risk test information set for the key area based on the non-standard parameters and the regional facility information;

[0130] The risk test information set is decomposed to obtain a plurality of test methods, and the training process corresponding to each test method is searched respectively. The training process is adaptively trained based on the regional facility information to generate the risk training information set of the key area.

[0131] The working principle and beneficial effects of the above technical solution are as follows: by cleaning the regional facility information and eliminating the interference data, the facility parameters of each regional facility in the key area are determined, and the risk test information set of the regional facilities is generated by mirroring, and then the risk training information set is determined by decomposition. This can improve the efficiency and quality of subsequent risk assessment.

[0132] Example 6

[0133] On the basis of Example 1, the method for assessing the security risk level of a key area, the step 3 comprises:

[0134] Step 31: collecting regional facility images of the key area within a specified period, locating each of the potential risk accidents in the regional facility images, and establishing a facility risk model for the key area based on the positioning results combined with the regional facility information of the key area;

[0135] Step 32: Collecting real-time dynamic information in the key area, inputting the real-time dynamic information into the facility risk model for real-time simulation, and obtaining simulated triggering information corresponding to each potential risk accident;

[0136] Step 33: using the risk trigger information to identify the trigger level of each of the simulated triggered information, obtaining the simulated trigger level of each of the simulated triggered information, and determining the potential occurrence level of each of the potential risk accidents;

[0137] Step 34: using the risk trigger information, respectively identify the triggering factors of each of the simulated triggered information, obtain the simulated triggering factors of each of the simulated triggered information, and determine the potential risk factors of each of the potential risk accidents.

[0138] In this example, the prescribed period is 15 days. The administrator can set the prescribed period according to actual needs.

[0139] In this example, the facility risk model represents the risk model used to simulate the key areas;

[0140] In this example, the real-time dynamic information refers to the real-time activity information in the key area;

[0141] In this example, the simulated triggered information represents the triggering situation of a potential risk accident.

[0142] The working principle and beneficial effects of the above technical solution are as follows: in order to screen out all potential risk factors in key areas, the regional facility images and regional facility information of key areas are used to construct a facility risk model for key areas, and then the model is used to simulate the real-time dynamic information in the key areas in real time to determine its corresponding simulated triggered information, and then the simulated triggered information is further level-identified to determine the potential level of occurrence of each potential risk accident, and finally each simulated triggered factor is identified to determine the potential risk factors of potential risk accidents. In this way, various risk factors in key areas can be screened out, and the potential level of occurrence of each potential risk accident can be determined, laying the foundation for subsequent risk warnings.

[0143] Example 7

[0144] On the basis of Example 1, the method for assessing the security risk level of a key area, step 4, comprises:

[0145] Step 41: Find target risk accidents whose potential occurrence level is higher than the specified occurrence level, trace the target potential risk factors of the target risk accidents, and obtain the risk source corresponding to each target potential risk factor;

[0146] Step 42: locating each of the risk sources in the key area, and determining the risk impact area corresponding to each of the target potential risk factors in combination with the target potential occurrence level corresponding to the target risk accident;

[0147] Step 43: respectively obtain the field information corresponding to each of the dangerous impact fields, generate the danger level of each of the dangerous impact fields, call the corresponding warning method to establish a danger warning list and display it.

[0148] In this example, the hazard source indicates the source of the target potential hazard factor;

[0149] In this example, the hazard impact area represents the scope of influence of the target potential factor.

[0150] The working principle and beneficial effects of the above technical solution are as follows: when the level of potential risk accidents in key areas is too high, trace the source of the accidents to determine the source of danger, and then analyze the dangerous impact area of ​​the target potential risk factors, and finally call for the corresponding early warning method to issue an early warning. In this way, the dangers in key areas can be identified and warned, effectively avoiding accidents in key areas.

[0151] Example 8

[0152] Based on Example 7, the security risk level assessment method for key areas further includes:

[0153] A danger guide is established according to the danger level corresponding to each of the danger impact areas in combination with the area attributes of the corresponding danger impact area, and the danger warning guide is transmitted to the area terminal corresponding to the corresponding danger impact area for display.

[0154] The working principle and beneficial effects of the above technical solution are: constructing a risk guide for each dangerous impact area, providing people with effective risk avoidance methods to avoid accidents.

[0155] Example 9

[0156] This embodiment provides a security risk level assessment system for key areas, such as Figure 2 As shown, including:

[0157] An information collection module is used to obtain a number of risk data of key areas, and establish risk trigger information corresponding to each of the key areas according to the risk type corresponding to each of the risk data;

[0158] An accident analysis module is used to use the risk trigger information to perform risk assessment on the regional facility information of the corresponding key areas to obtain a number of potential risk accidents corresponding to each of the key areas;

[0159] A hazard screening module is used to construct a facility risk model corresponding to each of the key areas, and determine the potential occurrence level and potential hazard factor corresponding to each of the potential risk accidents at the current moment in the facility risk model;

[0160] The danger warning module is used to locate the danger impact area corresponding to the potential danger factor in the key area when the potential occurrence level is higher than the specified occurrence level, generate a danger warning list and display it.

[0161] In this example, the key areas may be: residential areas, schools, gas stations, construction, commercial office buildings, public facilities, hazardous chemicals and industrial and mining enterprises, hotels and tourism, and road traffic;

[0162] In this example, since different key areas have different constituent facilities, their corresponding regional facility information is also different;

[0163] In this example, the risk type represents a means for distinguishing the risks that may occur in different key areas, and different key areas may correspond to several different types of risk types;

[0164] In this example, potential risk accidents refer to risk accidents that may occur in key areas;

[0165] In this example, the potential occurrence level indicates the level of risk if a risk accident occurs. Generally speaking, there are five levels, namely:

[0166] 1. Major risk (red risk): This level of risk has the highest severity, usually involves multiple risk factors, and is difficult to control. If an accident occurs, it may cause huge economic losses or heavy casualties;

[0167] 2. Greater risk (orange risk): This level of risk is also of high severity, involves more dangerous factors, and is more difficult to control. If an accident occurs, it may cause major economic losses or serious casualties;

[0168] 3. General risk (yellow risk): This level of risk is within the controllable range. Although it may cause certain economic losses or injury accidents, it usually does not cause serious consequences.

[0169] 4. Low risk (blue risk): This level of risk has the lowest severity and is usually under control. Even if an accident occurs, it will only cause general economic losses or minor injuries.

[0170] 5. No risk (green risk): This level of risk is not dangerous and is usually stable, that is, no accidents will occur. The worst case scenario is that the only non-injury accident can be solved by individuals themselves.

[0171] In this example, the potential risk factor indicates the cause of the risk incident. For example, if a pedestrian leaves a burning cigarette butt and encounters a suitable wind force, it may cause a fire. Then the burning cigarette butt and the corresponding wind force constitute the potential risk factor of the fire.

[0172] In this example, the occurrence levels are specified as: general risk and above, namely: general risk, relatively large risk and major risk;

[0173] In this example, the hazardous impact area refers to the area where potential hazardous factors have an impact on the key area;

[0174] In this example, the danger warning list lists all potential risks in key areas and issues corresponding warnings for potential risks with high danger levels.

[0175] The working principle and beneficial effects of the above technical solution: Since different key areas have different properties and different facility displays, before conducting a safety risk assessment, it is necessary to establish risk trigger information for key areas based on the risk data of key areas, and then conduct a risk assessment on the facilities in the key areas, determine the potential risk accidents contained in the key areas, and then build a model to analyze the level and cause of the risk at the current moment. Finally, conduct an in-depth analysis of potential risks at high risk levels, determine the scope of their hazardous impact, and generate a hazardous warning list in a timely manner to issue corresponding warnings. In this way, targeted safety analysis can be conducted on different types of key areas, reducing the occurrence of accidents and avoiding people’s property losses. In addition, during the assessment process, the safety level of each facility can be continuously monitored for a long time to analyze its stability, helping managers to make corresponding decisions.

[0176] Example 10

[0177] On the basis of Example 9, the safety risk level assessment system for key areas, the accident analysis module, includes:

[0178] A first analysis unit is used to obtain regional facility information of the key area, pre-process the regional facility information, generate a risk training information set and a risk test information set of the key area, perform risk assessment on the risk test information set using the risk trigger information, and obtain a plurality of assessment trigger factors contained in the key area;

[0179] A second analysis unit is used to search the risk level classification corresponding to each of the assessment trigger factors in the risk trigger information, perform trigger training on the assessment trigger factors using the risk training information to obtain a risk trigger value corresponding to each of the assessment trigger factors, and map the risk trigger value to the corresponding risk level classification to obtain a trigger risk level corresponding to each of the assessment trigger factors;

[0180] A third analysis unit is used to determine the risk item corresponding to each of the risk trigger factors according to the risk trigger information, establish a facility distribution map of the key area according to the regional facility information, locate the target area facility corresponding to each of the risk items in the facility distribution map, configure corresponding risk item characteristics for each of the target area facilities, and determine the risk impact characteristics between facilities in different areas based on the trigger risk level corresponding to each of the assessment trigger factors;

[0181] The fourth analysis unit is used to establish several types of risk impact data corresponding to the regional facilities according to the risk item characteristics and risk impact characteristics corresponding to each of the regional facilities, determine the work interference characteristics of the risk impact data on the corresponding regional facilities, and generate several potential risk accidents in the key areas.

[0182] In this example, the risk training information set refers to an information set that determines the risk levels of various risks through training;

[0183] In this example, the risk test information set represents an information set used to test risks in a key area;

[0184] In this example, the facility distribution map refers to a map used to depict the distribution of various types of facilities in a key area;

[0185] In this example, the risk event characteristics represent the characteristics presented by the target area facilities when a risk event occurs;

[0186] In this example, the risk impact feature indicates that a regional facility is affected by other regional facilities due to the support or restriction relationship between the regional facilities;

[0187] In this example, one risk item can correspond to one or more target area facilities;

[0188] In this example, the work interference feature represents the interference of risk impact data on regional facilities.

[0189] The working principle and beneficial effects of the above technical solution are as follows: In order to further determine the potential risks existing in the key areas, a risk training information set and a risk test information set are first formulated based on the regional facility information of the key areas, and then these two information sets are used to perform risk assessment to determine the assessment trigger factors contained in the key areas and the trigger risk level corresponding to each assessment trigger factor, thereby determining the risk items contained in the key areas, and locating the target regional facilities involved in each risk item in the facility distribution map of the key areas, and analyzing the risk impact between facilities in different areas to create risk impact data for each regional facility, and finally generating potential risk accidents in the key areas by analyzing the interference of the risk impact data on the regional facilities. In this way, various types of potential risk accidents contained in the key areas can be quickly located, and potential risk accidents in the key areas can also be located. If an accident occurs, corresponding rescue can be carried out in a timely manner, and early intervention can also be carried out before the accident occurs.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
