[0072] An embodiment of the present application provides a method for identifying the cause chain of general aviation flight accidents, as Figure 1 shown. The method includes:

[0073] 101. Obtain the accident investigation report of the target general aviation flight accident. Based on the mapping relationship between multiple accident cause subtypes and type descriptions, identify each unsafe action description included in the accident investigation report. Generate corresponding unsafe action names respectively according to each unsafe action description, and use each unsafe action name as the target unsafe action name one by one.

[0074] Among them, the accident investigation report records an overview of the occurrence process of the target general aviation flight accident. The cause chain involved in the present application is traced forward from the space-time point of the accident occurrence. Here, the space-time point refers to the point where the time point of the accident occurrence intersects with the longitude and latitude coordinates of the aircraft crash; the unsafe action description is used to characterize the description statement of the unsafe action sorted out according to the type description in the mapping relationship between multiple accident cause subtypes and type descriptions (as shown in Table 1, in Table 1, "violation of operation", "illegal command", etc. are accident cause subtypes, and "unsafe actions that violate general aviation laws, regulations, and safety management policies and procedures formulated by general aviation operating units to avoid accidents, and the action object is a specific physical object, such as a joystick, etc." is the type description), for example, when spraying pesticides, only staring at the high-voltage lines in the north-south direction and ignoring the high-voltage lines in the east-west direction, etc.; the unsafe action name is summarized according to the unsafe action description, for example, ignoring the high-voltage lines in the east-west direction, etc. In the embodiment of the present application, the current execution end can be a general aviation flight accident cause analysis module.

[0075] Table 1 Mapping relationship between accident cause subtypes and type descriptions

[0076]

[0077]

[0078] For example, first obtain the accident investigation report of the target general aviation flight accident: On a certain day, a helicopter with a certain number performed a task of spraying pesticides in a poplar forest in a certain place, with only one captain on board. The flight operation started at 08:30, and the first three sorties were normal. The fourth sortie started at 08:45, took off to the north, turned right to the southeast after takeoff, and when approaching the east-west high-voltage line, it rose to a height of 25 meters and flew over it, then descended and maintained a true height of about 5-10 meters, with a flight speed of 40-60 nautical miles per hour, and turned right to carry out the pesticide spraying operation. When the remaining amount of pesticide was about one-half, the captain flew the plane westward and prepared to spray the edge of the area. When the plane flew westward over the highway, the captain changed the route and flew northward along the highway, and prepared to turn right in time to spray the remaining pesticides. At this time, due to the low operating altitude and close field of vision, the captain completely ignored the east-west high-voltage wires. In addition, the terrain was undulating, there was a small amount of dust in the weather, and the sun was small in the morning, which affected the observation. When the east-west high-voltage wires suddenly appeared in the captain's sight, he immediately took the pole and pressed the left pole to avoid it, trying to fly the plane over the high-voltage wires, but it was too late. Further, the descriptions of each unsafe action contained in the accident investigation report were identified, and the corresponding unsafe action names were generated according to each unsafe action description, as shown in Table 2.

[0079] Table 2 Description of unsafe actions identified from accident investigation reports

[0080]

[0081]

[0082] It should be noted that the unsafe action categories in Table 2 are obtained by classifying the unsafe action descriptions into accident cause subtypes based on the mapping relationship between multiple accident cause subtypes and type descriptions. A detailed description will be given later and is only shown here in advance.

[0083] Furthermore, firstly, “ignoring the east-west high-voltage wire” is taken as the name of the target unsafe action.

[0084] 102. Based on the mapping relationship between multiple accident cause subtypes and type descriptions, identify the various indirect cause descriptions contained in the accident investigation report, and determine the indirect cause description that matches the target unsafe action name from the various indirect cause descriptions as the explicit indirect cause description of the target unsafe action name.

[0085] Among them, the indirect cause description is used to characterize the description statement of the indirect cause sorted out based on the type description in the mapping relationship between multiple accident cause subtypes and type descriptions according to the description in the accident investigation report. For example, focusing on pesticide spraying operations and ignoring external observation, etc.; the explicit indirect cause description is used to characterize the indirect cause description directly identified from the accident investigation report. Continuing the above example, the indirect cause descriptions identified from the accident investigation report are shown in Table 3.

[0086] Table 3 Indirect cause descriptions identified from the accident investigation report

[0087]

[0088] Among them, the indirect cause descriptions matching the target unsafe action name "ignoring the east-west high-voltage line" are "focusing on pesticide spraying operations and ignoring external observation" and "undulating terrain, floating dust and sun glare causing visual illusions", so they are used as the explicit indirect cause descriptions of "ignoring the east-west high-voltage line".

[0089] 103. Based on the target unsafe action name and the mapping relationship between multiple accident cause subtypes and type descriptions, determine the implicit indirect cause description of the target unsafe action name.

[0090] Among them, the implicit indirect cause description is used to characterize the indirect cause description that needs to be inferred. Continuing the above example, according to the unsafe action name "ignoring the east-west high-voltage line", analyze one by one whether it conforms to the type descriptions of each indirect cause accident cause subtype (including insufficient safety knowledge, low safety awareness, poor safety habits, unfavorable safety psychology, and unfavorable safety physiology), and it can be determined that it conforms to the accident cause subtype of insufficient safety knowledge, which can be described as "the captain does not understand the location and direction of the obstacles in the operation area", that is, the implicit indirect cause description of the target unsafe action name is determined to be "the captain does not understand the location and direction of the obstacles in the operation area".

[0091] 104. Respectively based on the explicit indirect cause description and the implicit indirect cause description, and based on the mapping relationship between multiple accident cause subtypes and type descriptions, sequentially perform the matching of the accident cause subtypes of safety management system deficiencies and the accident cause subtypes of safety culture deficiencies, and obtain the accident cause subtypes of safety management system deficiencies and the accident cause subtypes of safety culture deficiencies that match the explicit indirect cause description, as well as the accident cause subtypes of safety management system deficiencies and the accident cause subtypes of safety culture deficiencies that match the implicit indirect cause description.

[0092] Among them, the matching of the sub - type of accident causes of safety management system deficiencies means that according to the explicit indirect cause description and the implicit indirect cause description, it is analyzed one by one whether it conforms to the type description of each sub - type of accident causes of safety management system deficiencies, or from the accident investigation report, the description of safety management system deficiencies that conforms to the type description of each sub - type of accident causes of safety management system deficiencies is identified (as shown in Table 4); the matching of the sub - type of accident causes of safety culture deficiencies means that according to the sub - type of accident causes of safety management system deficiencies that have been matched, it is analyzed one by one whether it conforms to the type description of each sub - type of accident causes of safety culture deficiencies.

[0093] Table 4 Safety management system deficiencies identified from the accident investigation report

[0094]

[0095] Continuing with the above example, according to the implicit indirect cause description "The captain does not know the location and direction of the obstacles in the operation area", it is analyzed one by one whether it conforms to the type description of each sub - type of accident causes of safety management system deficiencies. It can be determined that it conforms to the sub - type of accident causes of operating procedure deficiencies and can be described as "lacking a flight mission statement", that is, the sub - type of accident causes of safety management system deficiencies that matches the implicit indirect cause description is obtained. Further, according to the safety management system deficiency description "lacking a flight mission statement", it is analyzed one by one whether it conforms to the type description of each sub - type of accident causes of safety culture deficiencies. It can be determined that it conforms to the sub - type of accident causes of safety integration management deficiencies, the sub - type of accident causes of the degree of responsibility of management level deficiencies, and the sub - type of accident causes of the implementation method of safety system deficiencies. The matching of the sub - type of accident causes of safety management system deficiencies and the matching of the sub - type of accident causes of safety culture deficiencies for the explicit indirect cause description are similar to the above process and will not be elaborated here.

[0096] 105. Link the name of the target unsafe action, the explicit indirect cause description, the sub - type of accident causes of safety management system deficiencies that matches the explicit indirect cause description, and the sub - type of accident causes of safety culture deficiencies to obtain an explicit accident cause chain, and link the name of the target unsafe action, the implicit indirect cause description, the sub - type of accident causes of safety management system deficiencies that matches the implicit indirect cause description, and the sub - type of accident causes of safety culture deficiencies to obtain an implicit accident cause chain. Combine the explicit accident cause chain and the implicit accident cause chain to obtain the action accident cause chain of the name of the target unsafe action.

[0097] In the embodiment of the present application, continuing with the above example, according to the causal relationship in steps 101 - 104 of the embodiment, link the name of the target unsafe action, the implicit indirect cause description, the sub - type of accident causes of safety management system deficiencies that matches the implicit indirect cause description, and the sub - type of accident causes of safety culture deficiencies to obtain an implicit accident cause chain, asFigure 2 As shown in the figure, in the figure, UA1--IC4--SMS1--SC2, SC4, SC5 are the hidden accident cause chains. Similarly, the obvious accident cause chains UA1--IC1--UA4--SMS2--SC2, SC4, SC5 and UA1--IC2--UC1 are obtained. Finally, the obvious accident cause chains and the hidden accident cause chains are combined to obtain the action accident cause chain of the target unsafe action name.

[0098] 106. Combine each action accident cause chain to obtain the accident cause chain of the target general aviation flight accident.

[0099] In the embodiment of the present application, by combining the action accident cause chains of all the unsafe actions identified in step 101 of the embodiment, the accident cause chain of the target general aviation flight accident can be obtained, as Figure 2 shown.

[0100] Compared with the prior art, in the embodiment of the present application, first, the unsafe actions and indirect causes are identified from the accident investigation report, and then the indirect cause that matches the unsafe action is selected from the indirect causes as the obvious indirect cause; further, based on the mapping relationship between multiple accident cause subtypes and type descriptions, the hidden indirect cause is determined according to the unsafe action; further, the upper-level causes of the obvious indirect cause and the hidden indirect cause are traced respectively, that is, the deficiencies in the safety management system and the safety culture, and they are linked according to the causal relationship to obtain the accident cause chain, realizing a comprehensive analysis of general aviation accidents, improving the clarity and enhancing the logic of the accident cause chain.

[0101] The embodiment of the present application provides another method for identifying the accident cause chain of general aviation flight accidents, as Figure 3 shown, the method includes:

[0102] 201. Obtain the accident investigation report of the target general aviation flight accident, and based on the mapping relationship between multiple accident cause subtypes and type descriptions, identify each unsafe action description included in the accident investigation report, generate corresponding unsafe action names respectively according to each unsafe action description, and use each unsafe action name as the target unsafe action name one by one.

[0103] 202. Based on the mapping relationship between multiple accident cause subtypes and type descriptions, identify each indirect cause description included in the accident investigation report, and determine the indirect cause description that matches the target unsafe action name from each indirect cause description as the obvious indirect cause description of the target unsafe action name.

[0104] 203. Based on the mapping relationship between multiple accident cause subtypes and type descriptions, determine the implicit indirect cause description of the target unsafe action name according to the target unsafe action name.

[0105] The implementation steps 201 - 203 of the embodiment can refer to the detailed description in the foregoing embodiment steps 101 - 103, and will not be elaborated here.

[0106] 204. According to the explicit indirect cause description and the implicit indirect cause description, conduct a sufficient and necessary verification on the implicit indirect cause description to determine that the implicit indirect cause description holds.

[0107] In the embodiment of the present application, the sufficient and necessary verification of the implicit indirect cause description can be based on the Causal Sufficiency Criterion (CSC). Specifically, continuing with the above example, the explicit indirect cause descriptions are: "Focusing on the pesticide spraying operation and neglecting external observation" and "The undulating terrain, floating dust, and the sun's glare caused visual illusions", and the implicit indirect cause description is: "The captain does not understand the location and direction of the obstacles in the operation area". First, conduct a sufficiency verification. Assume that "Focusing on the pesticide spraying operation and neglecting external observation", "The undulating terrain, floating dust, and the sun's glare caused visual illusions", and "The captain does not understand the location and direction of the obstacles in the operation area" exist simultaneously. Is it inevitable that "neglecting the east - west high - voltage line" will occur? The conclusion is yes, and the three together cause the captain to fail to identify the high - voltage line. Further, conduct a necessity verification. Assume that "neglecting the east - west high - voltage line" does not occur. Is at least one of the causes not valid? The conclusion is yes. For example, if the captain understands the location of the obstacles (i.e., "The captain does not understand the location and direction of the obstacles in the operation area" does not exist), the high - voltage line may be avoided in advance. Based on this, it is determined that the implicit indirect cause description "The captain does not understand the location and direction of the obstacles in the operation area" holds.

[0108] 205. According to the explicit indirect cause description and the implicit indirect cause description respectively, based on the mapping relationship between multiple accident cause subtypes and type descriptions, successively conduct the matching of the accident cause subtypes of safety management system deficiencies and the accident cause subtypes of safety culture deficiencies, and obtain the accident cause subtypes of safety management system deficiencies and the accident cause subtypes of safety culture deficiencies that match the explicit indirect cause description, as well as the accident cause subtypes of safety management system deficiencies and the accident cause subtypes of safety culture deficiencies that match the implicit indirect cause description.

[0109] The implementation steps 205 of the embodiment can refer to the detailed description in the foregoing embodiment steps 104, and will not be elaborated here.

[0110] 206. Link the target unsafe action name, the explicit indirect cause description, the accident cause subtypes of safety management system deficiencies and the accident cause subtypes of safety culture deficiencies that match the explicit indirect cause description to obtain an explicit accident cause chain, and link the target unsafe action name, the implicit indirect cause description, the accident cause subtypes of safety management system deficiencies and the accident cause subtypes of safety culture deficiencies that match the implicit indirect cause description to obtain an implicit accident cause chain. Combine the explicit accident cause chain and the implicit accident cause chain to obtain an accident cause chain for the target unsafe action name.

[0111] In the embodiments of the present application, in order to analyze general aviation accidents more comprehensively, the method of the embodiment further includes: based on the mapping relationship between multiple accident cause subtypes and type descriptions, identify each unsafe material state description included in the accident investigation report; add each unsafe material state description to the accident cause chain of the action to obtain an updated accident cause chain of the action, so as to generate an accident cause chain for the target general aviation flight accident based on the updated accident cause chain of the action.

[0112] Among them, the unsafe material state description is used to represent a description statement for the unsafe material state sorted out based on the type description in the mapping relationship between multiple accident cause subtypes and type descriptions according to the description in the accident investigation report. For example, the terrain of the operation area is uneven, there is a small amount of floating dust in the weather, the sun angle is small in the morning and the sunlight is dazzling, etc., as shown in Table 5.

[0113] Table 5 Unsafe material state descriptions identified from the accident investigation report

[0114]

[0115] Continuing with the above example, when analyzing the explicit indirect cause, it can be determined that the cause of the explicit indirect cause "the undulating terrain, floating dust and sun glare caused visual illusion" is the unsafe material state description "the terrain of the operation area is uneven, there is a small amount of floating dust in the weather, the sun angle is small in the morning and the sunlight is dazzling". Based on this, the explicit accident cause chain UA1--IC2--UC1 can be obtained.

[0116] In addition, based on the mapping relationship between multiple accident cause subtypes and type descriptions, each external factor deficiency cause description included in the accident investigation report can be identified; each external factor deficiency cause description is added to the accident cause chain of the action to obtain an updated accident cause chain of the action.

[0117] 207. Combine each accident cause chain of the action to obtain an accident cause chain for the target general aviation flight accident.

[0118] Step 207 of the embodiment can refer to the detailed description in step 106 of the foregoing embodiment, and will not be elaborated here.

[0119] 208. Classify each description involved in the accident cause chain, determine the accident cause type to which each description belongs, and count the number of accident cause types to determine the weak link causing the target general aviation flight accident.

[0120] Specifically, step 208 of the embodiment includes: based on the mapping relationship between multiple accident cause subtypes and type descriptions, classify each description involved in the accident cause chain of the target general aviation flight accident into accident cause subtypes to obtain the accident cause subtypes corresponding to each description; classify each accident cause subtype into accident cause types to obtain the accident cause types corresponding to each accident cause subtype; count the number of each accident cause type to determine the weak link causing the target general aviation flight accident.

[0121] Among them, the accident cause types include unsafe action accident cause types, unsafe physical state accident cause types, indirect cause accident cause types, safety management system deficiency accident cause types, safety culture deficiency accident cause types, and external factor deficiency accident cause types. Further, the unsafe action accident cause types include accident cause subtypes of violation of operation regulations, accident cause subtypes of violation of command, accident cause subtypes of violation of actions, accident cause subtypes of non-violation but causing accidents, and accident cause subtypes of poor emergency response; the unsafe physical state accident cause types include accident cause subtypes of physical environment and accident cause subtypes of technical environment; the indirect cause accident cause types include accident cause subtypes of insufficient safety knowledge, accident cause subtypes of low safety awareness, accident cause subtypes of poor safety habits, accident cause subtypes of unfavorable safety psychology, and accident cause subtypes of unfavorable safety physiology; the safety management system deficiency accident cause types include accident cause subtypes of safety policy deficiency, accident cause subtypes of organizational setup deficiency, accident cause subtypes of responsibility assignment deficiency, accident cause subtypes of operation procedure deficiency, accident cause subtypes of system procedure deficiency, accident cause subtypes of training program deficiency, accident cause subtypes of human resource deficiency, accident cause subtypes of financial resource deficiency, and accident cause subtypes of equipment and facility deficiency; the safety culture deficiency accident cause types include accident cause subtypes of deficiency in the importance of safety, accident cause subtypes of safety creating economic benefits deficiency, accident cause subtypes of safety integrating into management deficiency, accident cause subtypes of safety mainly depending on safety awareness deficiency, accident cause subtypes of the main responsibility of safety deficiency, accident cause subtypes of safety investment deficiency, accident cause subtypes of the role of safety regulations deficiency, accident cause subtypes of the formation of safety values deficiency, accident cause subtypes of the degree of responsibility of management deficiency, accident cause subtypes of the role of safety department deficiency, accident cause subtypes of the degree of employee participation deficiency, accident cause subtypes of safety training needs deficiency, accident cause subtypes of line departments being responsible for safety deficiency, accident cause subtypes of the role of safety management system deficiency, accident cause subtypes of the formation method of safety system deficiency, accident cause subtypes of the implementation method of safety system deficiency, accident cause subtypes of the type of safety inspection deficiency, accident cause subtypes of the treatment of safety performance deficiency, accident cause subtypes of the relationship between safety performance and human resources deficiency, accident cause subtypes of safety management between the company and contract units deficiency, and accident cause subtypes of emergency response ability deficiency; the external factor deficiency accident cause types include accident cause subtypes of laws and regulations deficiency, accident cause subtypes of local authority supervision deficiency, accident cause subtypes of design and manufacturing deficiency, and accident cause subtypes of deficiencies in relevant units of general aviation activities.

[0122] Continuing with the above example, the detailed catalog of each description involved in the accident cause chain of the target general aviation flight accident is shown in Table 6.

[0123] Table 6 Catalog of Accident Cause Descriptions

[0124]

[0125] Furthermore, classify each description into accident cause sub - types to obtain the accident cause sub - types corresponding to each description. Then, classify each accident cause sub - type into accident cause types to obtain the accident cause types corresponding to each accident cause sub - type, and count the quantities, as shown in Table 7.

[0126] Table 7 Accident Cause Statistics Table

[0127]

[0128]

[0129] According to Table 7, there are a total of 19 sub - types of accident - causing reasons in the table. Among the 6 types of reasons, lack of safety culture, lack of safety management system, indirect reasons, unsafe material conditions, and unsafe actions all contain at least 1 sub - type of reason. Among them, the category of lack of safety culture contains the most sub - types of reasons, indicating that the lack of safety culture is the fundamental reason for the target general aviation flight accidents, that is, the weak link.

[0130] In a specific application scenario, first, according to the general aviation flight accident cause classification and analysis model (as Figure 4 shown) and Table 1, starting from the unsafe actions and unsafe material conditions closest to the accident occurrence, follow the accident analysis path (as Figure 5 shown), and trace back successively forward the indirect reasons, reasons for lack of safety management system, reasons for lack of safety culture, and lack of external factors. Specifically for the 46 sub - type cause analysis paths, the first step is to identify the unsafe actions most closely related to the accident. Based on the definition of unsafe actions given in Table 1, identify and extract the unsafe actions in the accident report, and in accordance with the definitions and expressions of each sub - type of reason for unsafe actions given in Table 1, as well as the order of sub - types of reasons for unsafe actions, identify and classify the sub - types of reasons for unsafe actions successively in the following order: illegal operation, illegal command, illegal action, not illegal but causing accidents, and poor emergency response. Similar to the process of identifying unsafe actions and classifying their sub - types of reasons, it is necessary to successively identify the unsafe material conditions, indirect reasons, lack of safety management system, lack of safety culture, lack of external factors and their corresponding sub - types of reasons from the accident report. The process of using the general aviation flight accident cause classification and analysis model to specifically analyze a general aviation flight accident is as Figure 6 shown. It should be noted that in the process of analyzing and extracting accident causes, each identified unsafe action should be used as the starting point of a unit according to the significant expressions of each accident report (if n unsafe actions can be identified in an accident report, there will be n starting points), in accordance withFigure 3 For the process of , for each identified unsafe act, it is necessary to trace back in sequence the unsafe material conditions, indirect causes, deficiencies in the safety management system, deficiencies in safety culture, and causes of deficiencies in external factors that led to its occurrence. For each type of cause, its corresponding cause subcategory should be traced back in sequence and classified. The above process can identify the accident causes as comprehensively as possible and minimize the omission of accident causes. When analyzing the causes of general aviation flight accidents using the general aviation flight accident cause classification and analysis model, not every cause module can be directly extracted from the accident report information. Generally, the unsafe acts and unsafe material conditions in the accident can be directly obtained from the accident report and are relatively comprehensive. The lack of safety knowledge, low safety awareness, poor safety habits, unfavorable safety psychology, and unfavorable safety physiology in the indirect causes are also clearly expressed in the accident report or there is information for reasonable hypothetical inferences. For the identification of deficiencies in the safety management system, on the one hand, it can be obtained from the clear information in the accident report, and on the other hand, reasonable logical inferences need to be made based on the analysis results of the previous cause. The deficiencies in safety culture need to make reasonable hypothetical inferences based on the established items and their definitions and the analysis results of the causes of deficiencies in the safety management system. The determination of deficiencies in external factors is mainly based on the descriptive information obtained from the accident report.

[0131] The present application provides a method for identifying the cause chain of general aviation flight accidents. First, obtain the accident investigation report of the target general aviation flight accident. Based on the mapping relationship between multiple accident cause subtypes and type descriptions, identify each unsafe action description included in the accident investigation report, generate corresponding unsafe action names respectively according to each of the unsafe action descriptions, and use each of the unsafe action names as the target unsafe action name one by one. Secondly, based on the mapping relationship between multiple accident cause subtypes and type descriptions, identify each indirect cause description included in the accident investigation report, and determine the indirect cause description that matches the target unsafe action name from each of the indirect cause descriptions as the explicit indirect cause description of the target unsafe action name; at the same time, according to the target unsafe action name, based on the mapping relationship between multiple accident cause subtypes and type descriptions, determine the implicit indirect cause description of the target unsafe action name. Thirdly, respectively according to the explicit indirect cause description and the implicit indirect cause description, based on the mapping relationship between multiple accident cause subtypes and type descriptions, sequentially perform safety management system deficiency accident cause subtype matching and safety culture deficiency accident cause subtype matching to obtain the safety management system deficiency accident cause subtype and safety culture deficiency accident cause subtype that match the explicit indirect cause description, and the safety management system deficiency accident cause subtype and safety culture deficiency accident cause subtype that match the implicit indirect cause description. Further, link the target unsafe action name, the explicit indirect cause description, and the safety management system deficiency accident cause subtype and safety culture deficiency accident cause subtype that match the explicit indirect cause description to obtain an explicit accident cause chain, and link the target unsafe action name, the implicit indirect cause description, and the safety management system deficiency accident cause subtype and safety culture deficiency accident cause subtype that match the implicit indirect cause description to obtain an implicit accident cause chain, and combine the explicit accident cause chain and the implicit accident cause chain to obtain the action accident cause chain of the target unsafe action name. Finally, combine each action accident cause chain to obtain the accident cause chain of the target general aviation flight accident.Compared with the prior art, in the embodiment of the present application, first, unsafe actions and indirect causes are identified from the accident investigation report, and then the indirect cause that matches the unsafe action is selected from these indirect causes as the explicit indirect cause; further, based on the mapping relationship between multiple accident cause subtypes and type descriptions, the implicit indirect cause is determined according to the unsafe action; further, the upper-level causes of the explicit indirect cause and the implicit indirect cause are traced respectively, that is, the deficiencies in the safety management system and the safety culture deficiency, and they are linked according to the causal relationship to obtain the accident cause chain, realizing a comprehensive analysis of general aviation accidents, improving the clarity and enhancing the logic of the accident cause chain.
