Description

[Technical Field]

[0001] The present invention relates to an accident information management device, an accident information management method, and an accident information management program that organize information about accidents in the same type of equipment collected from various locations and build a collection of accident information (database or table). [Background technology]

[0002] For example, there are facilities that require regular inspections, such as cubicle-type high-voltage power receiving facilities (hereinafter simply referred to as "cubicles"). This is because facilities like cubicles have the characteristic that the scope and scale of damage can be large in the event of an accident, and therefore require high levels of safety and availability. Therefore, regular inspections are required to detect abnormalities and deterioration in the equipment installed in the facilities in order to prevent accidents from occurring.

[0003] For example, Patent Document 1 discloses a system that supports the detection of deterioration. During each inspection, an inspector takes an image of the work site using a mobile device. The image data is stored in a server. During the inspection, an image from the previous work is displayed on the mobile device. The inspector can proceed with the current inspection while referring to the image from the previous work. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-16079 Summary of the Invention [Problem to be solved by the invention]

[0005] With the above system, what can be seen from the accumulated images, i.e., changes in appearance, are the only indicators for determining the progression of deterioration. However, as equipment deterioration progresses and an accident occurs, there may be other signs that appear besides changes in appearance. If only changes in appearance are used as a judgment indicator, other signs may be overlooked, and the degree of deterioration may not be accurately determined. As a result, it remains difficult for inspectors on-site to predict what process, what factors, and when an accident may occur, or to conclude what measures should be taken to prevent an accident.

[0006] Therefore, an object of the present invention is to construct useful information to prevent accidents in a given facility. [Means for solving the problem]

[0007] An accident information management device according to one embodiment of the present invention includes an information acquisition unit, an information organization unit, and an information storage unit. The information acquisition unit acquires information about individual accidents that have occurred in a specified facility. The information organization unit generates individual accident information by classifying the acquired information into multiple items. The multiple items include a causative device related to the device within the facility that caused the accident and an accident cause related to the phenomenon that caused the accident. The information storage unit records a collection of accident information generated by the information organization unit.

[0008] According to the above configuration, information on individual accidents occurring in a specified facility is collected. The collected information is systematically organized into multiple categories, thereby generating individual accident information. The accident information includes the causative device related to the device that caused the accident and the accident cause related to the phenomenon that caused the accident. Conversely, the accident information management device collects information that should be categorized into the causative device and the accident cause as "information on individual accidents." This accident information is recorded in the information storage unit and forms a collection. In other words, a database of accident information is constructed. By referring to this collection of accident information, it is possible to easily grasp the tendency of what causes accidents when a certain device in the facility is the cause of an accident.

[0009] Let us assume that a power outage occurs and the cause of the power outage is identified as the phenomenon in which a switchgear did not perform its expected circuit breaker operation. The "switchgear" is a factor device. Identifying why the shutoff operation was not performed (for example, due to deterioration of the switchgear or freezing due to snow that had entered the casing) is believed to lead to the prevention of future power outages caused by switchgears.

[0010] Therefore, the cause of the accident as one of the multiple items may include direct causes, into which information about the phenomenon that was the direct cause of the accident is classified, and root causes, into which information about the factors that caused the direct causes is classified. The above "no shutdown operation was performed" is an example of information that should be classified as a direct cause among the causes of the accident. The accident information also includes the root causes related to the factors that caused this direct cause. The above "why the shutdown operation was not performed" corresponds to the root cause. Conversely, the accident information management device also collects information that should be classified as a root cause as "information about individual accidents." By building such a collection of accident information, it is possible to easily grasp the points to note in order to prevent accidents from occurring.

[0011] Let's assume that the cause of the switch not performing its cutoff operation is identified as being due to the switch's deterioration. Before an actual power outage occurs, an inspector may be able to sense through their five senses an event that suggests the progression of this deterioration (for example, discoloration of the switch's cover). Therefore, the multiple items may include warning signs, which classify information about signs that were confirmed before the occurrence of an accident.

[0012] The above-mentioned "events suggesting the progression of deterioration" correspond to information that should be classified as "signs requiring attention." Accident information also includes such signs requiring attention. By creating a collection of such accident information, it becomes easy to understand the points requiring attention to prevent accidents from occurring. The items may include damage amounts, which classify information about economic losses caused by the accident. The damage amounts include direct damage amounts and secondary damage amounts (damage to the company's image, decreased sales, stock price crashes, etc.).

[0013] According to the above configuration, by referring to the collection of accident information, when a certain device in the facility causes an accident, it is possible to easily grasp the tendency of the scale of the damage. The accident information management device may further include a view request receiving unit that receives a view request for the collection of accident information, and a view permission unit that permits the view request when a predetermined view condition is satisfied.

[0014] According to the above configuration, a person who requests to view a collection of accident information can easily understand the trends of accidents that occur when a certain device in a facility is the cause of an accident, as long as the person satisfies the viewing conditions. A typical example of a "viewing condition" is the condition of being a paid member of the viewing service. The accident information management device may further include a contribution calculation unit that calculates a contribution that quantitatively indicates the information value for each piece of accident information based on the amount and content of information classified into each of the multiple items.

[0015] According to the above configuration, the information value of each piece of accident information can be quantitatively evaluated. When a viewing request is made by an information provider of the accident information, the viewing permission unit may relax the viewing conditions in accordance with the degree of contribution of the accident information provided by the information provider. According to the above configuration, the viewing conditions for viewing other accident information are relaxed for those who provide accident information with high information value. A typical example of "relaxation" is a discount on membership registration fees. This creates an incentive for information providers to provide high-value information, making it possible to build a database with high information value.

[0016] The contribution degree calculation unit may correct the contribution degree so that the greater the number of times the accident information is referenced by viewers whose viewing requests are permitted, the higher the contribution degree of the accident information. According to the above configuration, the number of references indicates the depth of interest of people in the industry who deal with the equipment. Accident information that is of great interest can be properly evaluated as having high information value. The accident information management device may further include a reaction input unit for inputting reactions from viewers whose viewing requests have been permitted for each piece of accident information. The contribution calculation unit may correct the contribution degree so that the more reactions from viewers, the higher the contribution degree of the accident information.

[0017] According to the above configuration, accident information that has received a large response from viewers can be properly evaluated as having high information value. "Responses" include comments or flags (including adding a bookmark or pressing the like button). The accident information management device may further include an additional information input unit to which additional information from an information provider of the accident information is input. The contribution degree calculation unit may correct the contribution degree of the accident information so that the more additional information from the information provider, the higher the contribution degree of the accident information.

[0018] According to the above configuration, accident information that includes a large amount of additional information from information providers can be properly evaluated as having high information value. "Additional information" includes photos of the scene, replies to comments from viewers, etc. The inspection work may be carried out by the facility owner themselves, or may be outsourced to a safety inspection company that is licensed to carry out the inspection work commercially.

[0019] The plurality of items may include a provider attribute for classifying information relating to attributes of an information provider of the accident information. The contribution degree calculation unit may correct the contribution degree so that the contribution degree is higher when the information provider is a party involved in the ownership of the facility. According to the above configuration, when information is provided by the person involved, such as the owner of the facility where the accident occurred, the credibility of the information provided is higher, and it is more likely that accurate information can be used to respond to feedback from viewers. Such accident information can be properly evaluated as having high information value and as having contributed greatly to building a collection of accident information.

[0020] An accident information management method according to one embodiment of the present invention includes acquiring information relating to individual accidents that have occurred in a specified facility, classifying the acquired information into multiple categories including a causative device relating to a device within the facility that caused the accident and an accident cause relating to the phenomenon that caused the accident, generating individual accident information, and recording a collection of the generated accident information.

[0021] An accident information management program according to an embodiment of the present invention causes a computer to execute the above-described accident information management method. The above method and program have the same or corresponding technical features as the above device, and therefore, when a certain device in a facility is the cause of an accident, it is possible to easily grasp the tendency of the cause of the accident. [Effects of the Invention]

[0022] According to the present invention, it is possible to construct useful information to prevent accidents in a given facility. [Brief explanation of the drawings]

[Figure 2] 10A and 10B are diagrams showing an example of accident information, and 10C is a diagram showing an example of information added to the accident information. [Figure 3] FIG. 10 is a diagram showing an example of a display mode of accident information presented to a viewer. [Figure 4]FIG. 10 is a diagram conceptually illustrating a process of calculating a contribution degree. [Figure 5] FIG. 10 is a diagram conceptually illustrating a process for deriving an instrument coefficient calculation table. DETAILED DESCRIPTION OF THE INVENTION

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The same or corresponding elements are designated by the same reference numerals throughout the drawings, and detailed descriptions thereof will be omitted. (Application example) 1 collects information about individual accidents that have occurred in a specified facility, organizes the collected information in a systematic manner, and constructs and records a collection of accident information D. In this sense, the accident information management device 1 serves as a device that performs information processing for constructing an accident information database 80.

[0025] The accident information D is made available for viewing. In this sense, the accident information management device 1 serves as a device that performs information processing for executing the accident information database 80 viewing service. "Facilities" include, for example, electrical equipment, communications equipment, mechanical equipment (e.g., elevators, production equipment), air conditioning equipment, disaster prevention equipment, sanitary equipment, septic tanks, etc. Equipment that requires high safety and availability, such as equipment that requires regular inspections, is preferred. Such facilities are generally installed in relatively large-scale business establishments (hereinafter simply referred to as "facilities"). "Facilities" include, for example, factories, government buildings, schools, hospitals, hotels, sports facilities, entertainment facilities, commercial facilities, etc.

[0026] The "predetermined facility" refers to a certain facility of the same type among the various facilities exemplified above. In the following, this embodiment will be described using an example in which the predetermined facility is a high-voltage power receiving facility installed in various locations. High-voltage power receiving equipment transforms electricity received at high voltage (e.g., 6,600V or 3,300V) from a distribution line to low voltage (e.g., 100V or 200V) and supplies the electricity at low voltage to load equipment within the facility. A so-called "cubicle" is one type of high-voltage power receiving equipment. A cubicle comprises a housing and the equipment housed within. The housing is a grounded metal box with a front door that opens and closes the interior. The equipment includes transformers, meters, switches, and protective devices. The meters measure and display voltage, current, power, etc. The switches open and close circuits. The protective devices protect the equipment in the event of overcurrent, ground faults, abnormally high voltage, etc. Other equipment includes capacitors for improving the power factor.

[0027] (subject) In this document, a "service provider" is a person who has the authority to handle the accident information management device 1, and who provides a database construction service and a browsing service for the accident information D. A "service user" is a person (viewer) who uses such a viewing service, and is typically a party to the facility. Parties include, for example, the owner of the facility, the owner of the facility where the facility is installed, the manufacturer of the facility or the equipment installed therein, and a safety inspection company commissioned by the owner to inspect the facility.

[0028] The service provider sets conditions for using the service (for example, paid membership registration). By satisfying the conditions, the person involved in the facility is granted permission to view the accident information database 80 and becomes a service user. A service user can also be an information provider. An "information provider" is someone who provides information to a service provider about individual accidents that occur at equipment. Information providers can be broadly categorized as "parties involved" or "third parties." Parties are people involved in the ownership of the equipment, such as the owner of the equipment where the accident occurred or the facility in which it is installed. A third party is someone other than the parties involved, such as a safety inspection company that has been commissioned by the parties involved to inspect the equipment where the accident occurred.

[0029] (Accident information management device) In the unlikely event that an accident occurs at high-voltage power receiving equipment installed in various locations, the accident information management device 1 according to this embodiment acquires information about the accident from information providers. The provided information is organized and forms part of the accident information database 80. By using the browsing service, each person involved in the high-voltage power receiving equipment can refer to a much larger number of cases than their own experience. All parties involved can share a wealth of knowledge about the accident, which can be used to prevent similar accidents from occurring again.

[0030] To enhance such browsing services, the accident information management device 1 provides a place for communication between information providers and viewers. The accident information management device 1 quantitatively evaluates the value of the provided information. The evaluation takes into account not only the quantity and quality of the provided information but also the reaction from viewers. As an example of how the evaluation results can be used, information providers who provide highly valuable information are given preferential treatment when using the service.

[0031] This will encourage service users to provide as much information as possible about accidents, which tend to be perceived as negative in society (although this information is useful to those involved), and will also support the safe operation of high-voltage power receiving facilities throughout the country. The configuration of the accident information management device 1 according to this embodiment will be described in more detail below. The accident information management device 1 is realized, for example, by a server managed by a service provider or an information terminal used by an operator of the service provider. The server or information terminal is a computer equipped with a CPU, memory, and an input / output interface.

[0032] The accident information management program according to the present invention is installed on the computer and stored, for example, in its memory. The CPU reads the program from the memory and processes information according to the steps instructed by the program. This allows the computer to execute the accident information management method according to the present invention and function as the accident information management device 1. However, the accident information management program does not need to be stored in the same computer as the CPU that reads it, and may be stored on a server or cloud that is physically separated from the computer.

[0033] As shown in Figure 1, the accident information management device 1 includes an information storage unit 10, an information acquisition unit 11, an information organization unit 12, a viewing request acceptance unit 21, a viewing permission unit 22, a response input unit 23, an additional information input unit 24, a notification unit 25, and a contribution calculation unit 30. The information storage unit 10 stores user information, an accident information database 80, and a contribution calculation table 90. The user information is information about service users. The accident information database 80 is a collection of accident information D generated based on information acquired from information providers. The contribution calculation table 90 defines an evaluation scale used when evaluating the information value of each piece of accident information D. The information acquisition unit 11 acquires information on individual accidents that have occurred in specific facilities (high-voltage power receiving facilities) from an information provider. The information organization unit 12 generates individual accident information D by classifying the acquired information into multiple categories. The accident information database 80 is constructed by accumulating the accident information D generated in this manner.

[0034] (Accident information) 2(A) and 2(B) show an example of accident information D generated by the information organizing unit 12. The accident information D is generated by organizing information acquired from information providers into multiple items. In this embodiment, these multiple items include "basic information," "provider attributes," "facility attributes," "causing equipment," "cause of accident," "signs to be aware of," and "damage."

[0035] "Basic Information" is categorized as basic information about the accident. "Basic Information" is further divided into "Time of Occurrence," "Weather," and "Event," and the acquired information is classified into each of these sub-categories. "Time of Occurrence" is categorized as information that identifies the date the accident occurred, and "Weather" is categorized as information that identifies the weather at the time the accident occurred. "Event" is categorized as information that identifies the specific details of the accident (for example, fire, widespread power outage, etc.).

[0036] "Provider attributes" classifies information about the attributes of the information provider. "Provider attributes" is further divided into "provider name," "party / third party," "property handled," and "area," and the acquired information is classified into each of these subdivided items. "Provider Name" classifies information that identifies the name of the information provider. "Party / Third Party" classifies information that identifies whether the information provider is a party or a third party. "Properties Handled" classifies information about the types of properties handled by the information provider, and "Area" classifies information that identifies the main area of ​​activity of the information provider. Information about properties handled and areas does not have to be acquired as part of the information about the accident. The information may be acquired as part of the procedure for becoming a service user and stored in the information storage unit 10 as user information.

[0037] "Facility attributes" classifies information about the facility where the equipment where the accident occurred is installed. "Facility attributes" are further divided into "use," "size," "location," "regional characteristics," and "surrounding environment," and the acquired information is classified into each of these subdivided items. "Use" classifies information that specifies the use or type of facility. "Scale" classifies information that specifies the size of the facility (number of people and area). "Location" classifies information that specifies the location of the facility. "Area characteristics" classifies information about whether the facility is located in an environment that is prone to accidents geographically or climatically (for example, areas prone to salt damage, areas prone to snow damage, areas with heavy rainfall, areas with heavy snow and cold weather, etc.). Even for equipment with the same specifications, the rate of deterioration (likelihood of accidents occurring) can vary depending on the characteristics of the area. "Surrounding environment" classifies information about the environment around the facility (for example, close to residential areas, mountainous areas, plains, etc.). Even for accidents involving the same phenomenon, the extent of damage can vary depending on the surrounding environment.

[0038] "Causing Equipment" classifies information about the equipment in the facility that caused the accident. "Causing Equipment" is further divided into "Type," "Manufacturer," "Model," and "Excessive Age," and the acquired information is classified into each of these subdivided items. "Type" classifies information that identifies the type of equipment that caused the accident (for example, high-voltage cable, PAS, etc.). "Manufacturer" classifies information that identifies the manufacturer of the equipment in question, and "Model" classifies information that identifies the product number of the equipment in question. "Exceeding years" classifies information that identifies the number of years that have passed since the expiration date of the equipment in question at the time the accident occurred. The expiration date is the limit of the useful life as determined by the manufacturer, etc. A positive value is entered if the accident occurred after the expiration date, and a negative value is entered if the accident occurred before the expiration date.

[0039] "Cause of accident" is classified as information that identifies the phenomenon that caused the accident. "Cause of accident" is further divided into "direct cause" and one or more "root causes," and the information obtained is classified into each of these subdivided items. "Direct causes" classifies information about the phenomenon that was the direct cause of the accident (for example, a short circuit, a switch not breaking, etc.). "Root causes" classifies information about the phenomenon that caused this direct cause (for example, poor insulation, deterioration of coating, snow and ice, etc.).

[0040] "Caution Signs" refers to information about signs that were observed before the accident occurred (for example, discoloration of the coating, remaining snow after a snowfall, etc.). "Signs" specifically refer to symptoms that may suggest the occurrence of the underlying cause. "Damage" is a category that includes information about damage caused by the occurrence of an accident. "Damage" is further divided into "amount of damage," "compensation amount," "self-paid amount," and "recovery period," and the information obtained is classified into each of these subdivided items.

[0041] "Damage amount" is information about the economic losses caused by the accident, especially information that specifies the total amount of economic losses. "Compensation amount from other companies" and "Self-paid amount" are entered as a breakdown of the "Damage amount" for each payer. "Recovery period" is information that specifies the number of days required from the occurrence of the accident to the restoration of the equipment. In order to obtain as much information as possible covering a wide range of items as described above, the service user is presented with a format to be used when providing information. The information provider inputs information about the accident according to the format in which the above-mentioned multiple items are listed. This simplifies the information organization process by the information organization unit 12.

[0042] As shown in FIG. 2(C), each piece of accident information D is supplemented with additional information from the information provider and information regarding reactions from viewers. The additional information includes image information of the scene. The image information may be attached to the information regarding the accident. When the information organizing unit 12 generates the accident information D, there is naturally no reaction from viewers to the accident information D. When this accident information D is made available for viewing, information regarding reactions is added as needed. Image information may be added after the accident information D is made available for viewing as part of a response to the reaction from the information provider.

[0043] (View) Returning to FIG. 1 , the viewing request receiving unit 21 receives a viewing request for the accident information database 80 from an information terminal communicatively connected to the accident information management device 1. The viewing permission unit 22 determines whether the information terminal that made the viewing request satisfies predetermined viewing conditions, for example, by referring to user information. The viewing conditions are, for example, a condition that the user has registered as a member of the service and a condition that the necessary fees have been properly paid. If such viewing conditions are met, the viewing permission unit 22 permits the viewing request from the information terminal.

[0044] Fig. 3 shows an example of the display mode of information presented to the viewer. As shown in Fig. 3, first, for example, a list of multiple pieces of accident information D stored as an accident information database 80 is displayed. At this time, only a portion of the multiple items constituting the accident information D is displayed. Here, only the time of occurrence, event, facility use, type of causative equipment, direct cause, and amount of damage are picked up as a portion of the items initially displayed, but there is no particular limitation on the types of items that are displayed.

[0045] In this list, a check box B1, a detail display button B2, and a comment button B3 are displayed for each piece of accident information D. The viewer can press the detail display button B2 and the comment button B3 on the screen using a pointing device such as a mouse. When the detail display button B2 is pressed, the list initially displayed is replaced with details of the accident information D, i.e., information on all or almost all items of the accident information D stored in the information storage unit 10. In addition, if image information has been uploaded by the information provider, the images are also displayed.

[0046] When the detail display button B2 is pressed, the reaction input unit 23 counts up the number of times the accident information D has been referenced by viewers (hereinafter referred to as the "reference number") and updates information regarding the reaction added to the accident information D. When the comment button B3 is pressed, a screen for entering a comment appears. Comments are structured in a thread format, and the viewer can choose to create a new thread or add a comment to an existing thread. The viewer can add a comment to the accident information D by using an input device such as a keyboard. The viewer can also use this thread format comment function to ask the information provider a question about the accident information D.

[0047] The input comment may be saved as one item in the table format shown in Figures 2(A) to 2(C), or may be saved as separate data in the information storage unit 10. This allows viewers to refer to the same question or answer that interests them as important additional information when it is saved as a comment, thereby improving the quality and quantity of the saved information.

[0048] When a comment is posted on the accident information D, the notification unit 25 notifies the information terminal used by the information provider of this fact. The information provider can input a reply to the comment added by the viewer. The input reply is input into the additional information input unit 24 and attached to the comment of the viewer to whom the reply is sent, forming a thread together with the viewer's comment. The information provider can also attach an image to this reply for the viewer's reference. When a reply is input by the information provider, the notification unit 25 notifies the information terminal used by the viewer to whom the reply is sent of this fact. This supports smooth communication between the viewer and the information provider.

[0049] In addition, the comments are available for viewing by service users other than the person who wrote them. In other words, for viewers, the comments themselves become supplementary material to the accident information D. When a comment is input from a viewer or an information provider, the reaction input unit 23 counts up the number of comments added to the accident information D, and updates information relating to the reaction added to the accident information D.

[0050] A viewer can use a pointing device such as a mouse to mark or unmark the check box B1. This check box B1 is a flag that indicates whether the article was useful (a so-called "Like button") or functions as a bookmark for future reference. If the viewer finds the article useful or would like to refer to it later, they can mark the check box B1, which sets the flag.

[0051] When a mark is added by a viewer, the reaction input unit 23 counts up the number of flags added to the accident information D, and updates the information related to the reaction added to the accident information D. As shown in Figure 3, the list initially presented to the viewer may display the number of uploaded images, the number of views, the number of comments, etc. This allows the viewer to easily gauge the level of response to each piece of accident information D. The accident information database 80 may also be processed into dashboard information using a BI (business intelligence) tool and then made available for viewing by viewers, making it easier for viewers to analyze accident information and helping them take measures to prevent accidents from occurring.

[0052] (Contribution) The contribution calculation unit 30 refers to the contribution calculation table 90 and calculates a contribution C that quantitatively indicates the information value for each piece of accident information D based on the amount and content of information classified into each of a plurality of items.

[0053] Fig. 4 conceptually shows the process of calculating the contribution degree C. The contribution degree calculation table 90 includes a raw score calculation table 91, a comment quality coefficient calculation table 92, a damage coefficient calculation table 93, an equipment coefficient calculation table 94, and an attribute coefficient calculation table 95. The contribution degree C is calculated by the following formula (1) (see also Fig. 4). C=Σ[α∈A]α × β × γ × δ ……(1) Here, Σ[α∈A]α is the sum of the elements constituting set A, i.e., the raw score αi (in this embodiment, i=1 to 7, for example). β is a damage coefficient calculated according to the damage amount X. γ is an equipment coefficient calculated according to the type of factor equipment. δ is an attribute coefficient calculated according to the correlation between the provider attribute and the facility attribute.

[0054] The contribution calculation unit 30 refers to the raw score calculation table 91 and calculates the raw score αi of the contribution C for each of the seven items. The contribution calculation unit 30 calculates the basic value Σα of the contribution C by adding up the raw scores αi. Meanwhile, the contribution calculation unit 30 derives the coefficients β, γ, and δ by referring to each of the coefficient calculation tables 93 to 95. The contribution calculation unit 30 calculates the contribution C by multiplying the basic value Σα by the coefficients β, γ, and δ.

[0055] <Raw score> The contribution calculation unit 30 calculates a first raw score α1 depending on whether the information provider is a party to the information or a third party. A score is assigned only if the information provider is a party to the information, and this score is higher than the other second raw scores α2 to seventh raw scores α7. In this regard, information provided by the parties involved, such as the owner of the equipment that caused the accident, is based on a willingness to share information that is often perceived as negative in society, and is therefore considered to be an act that should be respected. Furthermore, information provided by the parties involved is considered to be more credible and to be able to respond accurately to feedback from viewers. The presence of the first element score α1 allows accident information D from the parties involved to be properly evaluated as being of high value.

[0056] The contribution calculation unit 30 calculates a second raw score α2 according to the number of pieces of information classified as root causes. A root cause is information about the fundamental cause of the phenomenon that directly caused the accident. Identifying not only the direct cause but also the root cause through an investigation after the accident is thought to lead to the prevention of similar accidents from recurring. The existence of the second raw score α2 allows accident information D, which deeply addresses the root cause, to be properly evaluated as having high value.

[0057] The contribution calculation unit 30 calculates a third raw score α3 according to the number of pieces of information classified as signs requiring attention. Signs requiring attention are information about phenomena that suggest the occurrence of the above-mentioned root causes. The more knowledge an inspector has about signs requiring attention, the less likely they are to overlook abnormal signs during regular inspections, and this can be reflected in the inspection results. The existence of the third raw score α3 allows accident information D, which contains valuable information useful at the work site, to be properly evaluated as having high value.

[0058] The contribution calculation unit 30 calculates a fourth raw score α4 according to the number of images. There are limits to expressing things in words, and image information contains significantly more information than text information. The more images there are, the more substantial the accident information D becomes. The existence of the fourth raw score α4 makes it possible to properly evaluate highly substantial accident information D as having high value. The contribution calculation unit 30 calculates a fifth raw score α5 according to the number of references, and calculates a sixth raw score α6 according to the number of flags. The number of references reflects the level of demand or interest among industry participants. The number of flags simply represents the quality of the evaluation by industry participants. The existence of the fifth raw score α5 and the sixth raw score α6 allows accident information D, which has received a great response from viewers (almost synonymous with stakeholders), to be properly evaluated as having high value.

[0059] The contribution calculation unit 30 calculates a seventh raw score α7 according to the number of comments. The second raw score α2 to the sixth raw score α6 are proportional to the number of pieces of information, and the score per piece is set to a fixed value as the proportionality constant. A score is calculated for each comment according to its quality. Specifically, the score for each comment is calculated by multiplying a predetermined base value (for example, 20 points) per comment by a quality coefficient q according to the content of the comment. The scores calculated for each comment in this way are added up to calculate the seventh raw score α7.

[0060] The contribution calculation unit 30 derives the quality coefficient q for each comment by referring to the comment quality coefficient calculation table 92. In this embodiment, based on the idea that the quality of a comment is positively correlated with its quantity, the quality coefficient q is determined based on the number of characters. This allows the quality of a comment to be easily evaluated even without a tool for interpreting the content of the comment. Comments that do not directly mention accident information D, such as simple greetings, are likely to have a small number of characters. On the other hand, questions about detailed information and detailed responses to those questions are likely to have a large number of characters. Therefore, for comments that are less than a certain number of characters (for example, less than 20 characters), the quality coefficient q is set to zero, and the score for the comment is also set to zero (20 x 0 = 0). As the number of characters increases, the quality coefficient q also increases gradually.

[0061] Images convey more information than text, making them extremely useful as supplemental materials for text. Therefore, for comments with attached images, the quality factor q, derived based on the number of characters, is doubled. In the example shown, if an image is attached to a comment with 20 to 100 characters, the quality factor q is 6 (= 2 × 3), and if an image is attached to a comment with over 100 characters, the quality factor q is 10 (= 2 × 5). In this way, the more comments there are and the higher the quality of the comments, the more information the accident information D provides to viewers. The existence of the seventh element score α7 allows such accident information D to be properly evaluated as being of high value.

[0062] <Coefficient> The basic value Σα of the contribution C is the sum of the raw scores αi. The basic value Σα is increased by coefficients β, γ, and δ that are 1 or greater. As a result, if there are circumstances that allow the contribution C to be evaluated as high from a perspective other than the items referenced to calculate each raw score αi, the final contribution C will be a numerical value higher than the basic value Σα. In this embodiment, the amount of damage and provider attributes are taken into consideration as the "circumstances."

[0063] The contribution calculation unit 30 refers to the damage coefficient calculation table 93 and derives the damage coefficient β based on the damage amount X of the accident information D. The damage amount X simply and quantitatively indicates the risk itself that occurs due to an accident. The larger the damage amount X of an incident, the more desirable it is to prevent recurrence. In the illustrated example, the damage coefficient β increases stepwise as the damage amount X increases. This allows accident information D for incidents that should be prevented to be properly evaluated as having high value.

[0064] The contribution calculation unit 30 refers to the equipment coefficient calculation table 94 and derives the equipment coefficient γ based on the type of the factor equipment in the accident information D. If the factor equipment increases the amount of damage, an equipment coefficient γ of 1 or more is derived, and the contribution C is increased. To perform this processing, the contribution calculation unit 30 evaluates in advance the correlation between the factor devices and the damage amount, as shown in Fig. 5. In the illustrated example, the number of multiple pieces of accident information D accumulated as the accident information database 80 is 500, and the total damage amount for the 500 pieces of accident information D is 5 billion yen. The contribution calculation unit 30 tallies the damage amount for each device, sorts the tallied results (damage amount by element) in descending order, and calculates the ratio of each damage amount by element to the total damage amount.

[0065] When the ratio of the contributing equipment exceeds a predetermined value (e.g., 20%), the equipment coefficient γ becomes a value greater than 1 (e.g., γ=1.2). In the illustrated example, the ratio of PAS and transformers exceeds 20%. For accident information D in which the type of contributing equipment is PAS or transformer, the basic value Σα is increased and corrected by the equipment coefficient γ. Equipment with a high ratio is equipment that is prone to accidents and / or equipment that is likely to cause significant damage when an accident occurs. In order to reduce the number of accidents or the damage caused by accidents, it is thought that preventing recurrence of accidents caused by the equipment in question would be effective. Accident information D for such cases can be properly evaluated as being of high value.

[0066] The contribution calculation unit 30 refers to the attribute coefficient calculation table 95 and derives the attribute coefficient δ depending on whether there is a correlation between the provider attribute and the facility attribute. The contribution calculation unit 30 compares the property handled by the provider attribute with the facility use of the facility attribute within the same accident information D. The contribution calculation unit 30 also compares the area of ​​the provider attribute with the location of the facility attribute within the same accident information D. If any one of them matches, the attribute coefficient δ becomes a value greater than 1 (for example, δ = 1.1).

[0067] If the property handled by the information provider in their daily work matches the use of the facility where the equipment where the accident occurred is installed, it is believed that the information provider will be able to conduct a deeper analysis of accident information D (investigating the root causes and warning signs). The same applies if the area matches. Therefore, it is believed that accurate and detailed information will be provided. Such accident information D can be properly evaluated as having high value.

[0068] <Example> For accident information D, No. 1, the information provider is a third party, the number of pieces of information on root causes is 3, the number of pieces of information on warning signs is 3, the number of images is 8, the number of references is 200, and the number of flags is 30. There are 10 comments. There are 4 comments of 20 characters or less, 4 comments of 100 characters or less without images, 1 comment of 100 characters or less with an image, and 1 comment of over 100 characters without an image, and the seventh raw score α7 is 460 points. In this case, the basic value Σα is 1910 points.

[0069] The damage amount is 39 million yen, so the damage coefficient β is 4. The type of factor equipment is not a PAS or a transformer, so the equipment coefficient γ is 1. The property handled by the information provider matches the facility use, so the attribute coefficient δ is 1.1. Therefore, the basic value Σα is multiplied by 4.4, and the contribution C is 8,404 points. For accident information D of No. 2, the informant is the party involved, the number of pieces of information on the root cause is 2, the number of pieces of information on warning signs is 2, the number of images is 4, the number of references is 0, the number of flags is 0, and the number of comments is 0. In this case, the basic value Σα is 3600 points. The damage amount is 19 million yen, so the damage coefficient β is 2. The type of factor equipment is PAS, so the equipment coefficient γ is 1.2. The property handled by the information provider matches the facility use, so the attribute coefficient δ is 1.1. Therefore, the basic value Σα is multiplied by 2.64, and the contribution C is 9,504 points.

[0070] <How to use> Contribution C is returned to information providers when they use the service. The higher the contribution C, the more relaxed the viewing conditions for information providers. For example, the membership registration fee will be discounted.

[0071] (Action and effect) According to an accident information management device 1 of one embodiment of the present invention, information on individual accidents that have occurred in a specified facility is collected. The collected information is systematically organized into multiple categories, thereby generating individual accident information D. The accident information D includes a causative device related to the device that caused the accident and an accident cause related to the phenomenon that caused the accident. Conversely, the accident information management device 1 collects information that should be categorized into a causative device and an accident cause as "information on individual accidents." This accident information D is recorded in the information storage unit 10, forming an accident information database 80. By referring to this accident information database 80, it is possible to easily grasp the tendency of accidents occurring when a certain device in the facility is the cause of an accident.

[0072] The value of the accident information D is then quantitatively evaluated, and information providers who provide highly valuable information are given preferential treatment for using the service according to their contribution C. This will encourage service users to provide as much information as possible about accidents, which tend to be perceived as negative in society. This will also support the safe operation of facilities installed in various locations.

[0073] (Variation) The embodiments of the present invention have been described above, but the above configurations can be appropriately changed, added, and / or deleted within the scope of the present invention. (A) When information about the same accident is obtained from different information providers, only one of them may be added to the accident information database 80. Whether or not the accidents are the same can be determined from the time and location of the accident.

[0074] (B) In the above embodiment, the "predetermined facility" is a cubicle, and the accident information management device 1 collects accident cases of the cubicle. However, the accident information management device 1 can also be applied to electrical facilities other than cubicles and various facilities other than electrical facilities.
