In response to this, the data classification / search unit 16 refers to the type data, the cause data, and the like among the data set stored in the accident database 18 and determines the number of incidents and the number of casualties for each accident type. The counted value is provided to the image / form creation unit 30. FIG. 19 is a diagram showing a driving accident totalization table obtained in this manner.

A required form can be obtained by the same procedure. For example, the operator operates the mouse to operate a “railroad driving accident notification form (fifth style)” button 1712.
Is picked up, the fact is transmitted to the control unit 14 via the input device 12. The control unit 14 instructs the data classification / search unit 16 to read necessary data from various databases. The data classification / search unit 16
In response to this, of the data sets stored in the accident database 18, the number of cases is counted for each cause of the accident with reference to the cause data and the like, and the obtained value is stored in the image / form creation unit 30. Give to. FIG. 20 is a diagram showing the railway driving accident notification form obtained in this manner.

As described above, according to the present embodiment, various data related to an accident are stored in the accident database 18, the countermeasure database 22 and the human error database 20, and the data classification / search unit 16 is required. In response, predetermined data is searched from these databases, and an image based on the data is displayed on the screen of the CRT 32 or output from the output device 34 as a printed matter. Therefore, the operator can refer to the information on the accident as desired, and can obtain necessary forms by simple operations when necessary.

Next, the analysis countermeasure / formulation unit 26 of the security management support system 10 according to the present embodiment will be described in detail. As shown in FIG.
An analysis / evaluation unit 40 for grasping / analyzing the accident situation and analyzing the cause of human error, a diagnosis unit 42 for obtaining a safety diagnosis based on the analysis result of the analysis / evaluation unit 40, A prediction / measure generation unit 44 for proposing a measure for prevention.

The analysis / evaluation unit 40 responds to the control unit 14 receiving a signal indicating an instruction to grasp and analyze the accident situation, and the data classification / search unit 16 uses the databases 18 and 20 , 22 are configured to perform the following seven analyzes based on the data read out. These seven analyzes are (1) year-on-year analysis,
(2) Factor composition ratio analysis, (3) ABC analysis (filling factor control chart creation), (4) time series analysis, (5) risk curve (loss / frequency curve) analysis, (6) countermeasure effect analysis and (7) ) Consisting of correlation analysis.

In the year-on-year analysis, various types of information on accidents are compared for each type of accident, for each year, for each year, or for a certain period of time, such as at a certain point in time and before and after. Then, tables and graphs based on this are created. In the factor composition analysis, a graph showing the type of the accident and the composition of the cause is created. In the ABC analysis, they are arranged in descending order of the number of accident causes and in descending order of the degree of influence (maximum delay or total delay of trains).
The cause (management factor) occupying 0% or 80% is examined. In time series analysis, year,
A time axis such as a month, a day, a time, or a day of the week is set, and a graph or the like describing the number of accidents in each time unit is created. In the risk curve analysis, a logarithmic graph is created in which the horizontal axis represents the amount of loss and the vertical axis represents the frequency. In the countermeasure effect analysis, a table based on a cross analysis of whether or not the countermeasure is effective (for example, before and after mounting the safety device) is created. Further, in the correlation analysis, a table or a graph showing a correlation between two factors (for example, a small accident and a large accident) is created.

These analyzes are executed by the operator operating the input device 12 to select any one of the above-mentioned seven analyses. The instruction from the input device 12 is provided to the analysis / evaluation unit 40 via the control unit 14. The analysis / evaluation unit 40 designates necessary data, and
This is transmitted to the data classification / search unit 16 via the control unit 4. For example, in the case of performing year-on-year analysis, an instruction indicating that a set of data on accidents of a specified year and type is read from the accident database 18 and the countermeasure database 22 is transmitted to the data classification / search unit 16. .

The data read by the data classification / retrieval unit 26 is given to the analysis / evaluation unit 40, and the analysis / evaluation unit 40 responds to this by performing necessary processing (for example, for each type of accident). (Eg, calculation of the number of cases, sorting in the order of the number of cases, etc.), and outputs data obtained as a result of the processing to the image / form creation unit 30. The image / form creation unit 30 generates image data such as a table and a graph, and outputs the image data to the CRT 32 or the output device 34. This allows the operator
It is possible to obtain a desired analysis result.

The analysis / evaluation unit 40 responds to the control unit 14 receiving a signal indicating an instruction to analyze the cause of the human error, and the data classification / search unit 16 uses the human error database. Based on the data read from 20, the cause of the accident caused by the human error is analyzed, and the accident occurrence mechanism is analyzed. That is, based on data corresponding to the results of a questionnaire including a plurality of survey items in the human error database 20, the factors involved in the occurrence of the accident and the type of error are analyzed. More specifically, data for generating a graph or a table statistically representing the cause of the error is generated. A graph or table based on the obtained data is displayed on the screen of the CRT 32 via the image / form creation unit 30 or output as a printed matter from the output device 34.

Next, the diagnosis section 42 will be described in more detail. The diagnosis unit 42 is provided to evaluate the safety level of each line section based on the accident results. In the safety diagnosis, it is important to evaluate not only the number of accidents but also the quality of the accidents. In this embodiment, based on the analysis results of driving accidents, safety, stability,
Diagnosis is available for five items: economic, social and remedial.

Here, in the evaluation of safety, first,
In addition to grasping the total number of accidents during a predetermined period or a line section, the number of serious accidents such as a train derailment or a collision accident is grasped by referring to the accident type. Furthermore, based on the accident evaluation data (see reference numeral 308 in FIG. 3) in the data set of the grasp and accident database 18, the transition probability is calculated by referring to the past accident statistics, and the accident can be expanded. Gender (potential danger), that is, an index indicating how many accidents could have developed. In the evaluation of the stability, a numerical value that takes these into account is obtained based on the maximum delay of the train, the total delay, and the train suspension information. This makes it possible to obtain a degree of stable transport. In addition, the time until recovery in each accident is calculated.

In the evaluation of the economic efficiency, the cost performance of the investment is evaluated based on the amount of direct damage caused by the accident, the amount of indirect damage caused by transfer transportation, etc., and the amount of capital investment for ensuring safety. calculate. More specifically, referring to the impact data 306 included in the data set of the accident database and, if necessary, the data in the facility information database 60,
The amount of damage from the accident and the amount of capital investment are obtained, and the cost performance is calculated based on this.

In the evaluation of sociality, an index indicating the creditworthiness of the railway company is created based on how many passengers were affected by the accident or how much the accident was taken up as a newspaper article. In addition, based on the size of the accident in newspapers,
When creating an index indicating the degree of credit, it is necessary to prepare in advance in the impact data 306 data indicating the magnitude of the accident taken up.

In the evaluation of the improvement, the data indicating “accident type” in the type data is referred to.
Create an indicator of how often similar incidents occur.

As described above, the diagnostic section 42 can obtain indices for the above-described five items. This index is displayed on the screen of the CRT 32 via the image / form creation unit 30, or is output from the output device 34 as a printed matter.

Next, the human error safety diagnosis by the diagnosis unit 42 will be described. In this diagnosis, the contents and properties of the human error are evaluated using the data obtained by the human error analysis of the analysis / evaluation unit 40, and through this, a safety diagnosis of the entire railway company, departments and other organizations is generated. I do.

More specifically, in this embodiment, a plurality of evaluation indices having contents that contribute to safety management are prepared. These indices are configured to weight each item on the analysis sheet according to the aspect of the error to be evaluated. This weighting is determined by expert judgment by a human factor expert. Next, the rating values of the respective items in the analysis sheet are weighted as described above, and the values of the weighted items are summed to obtain the score of the accident.

The indices obtained as described above include (a)
Error maturity and (b) error negligence are conceivable.
“Error maturity” is based on “errors that occur in inexperienced situations” and “errors that occur in common operations”, and how much human error is biased to which side. It is a scale for checking whether or not This makes it possible to determine whether there are many “new type accidents” or “repeated accidents”. Further, it can be determined whether an accident often occurs when the party is inexperienced or when the party is an expert.

The "error degree of error" includes "an error that may have occurred if you noticed that you were working with caution," and "impossible while knowing that there was danger. This is a measure for examining how much the human error is biased to which side and how much error is caused by performing the above operation. This can suggest the direction of what measures should be taken for safety management.

Next, the prediction / measure generation unit 44 will be described. The prediction / countermeasure generation unit 44 generates the accident database 18 according to the type, time and / or location of the accident.
Necessary data and the like are read from the countermeasure database 22 and the knowledge base 28, and possible accidents and countermeasures are obtained.

More specifically, when the operator operates the input device 12 to specify at least one of the type, time, and location of the accident, the data relating to the prediction and countermeasure generation is generated via the control unit 14. Section 44. Next, the prediction / countermeasure generation unit 44 determines the type, time, place, and / or weather of the accident indicated by the given data.

In response to this, the data classification / search unit 16 searches the accident database 18 for a corresponding data set, and further takes a measure based on the ID data of the searched data set (see reference numeral 301 in FIG. 3). A necessary data set is searched from the database 22, and the data set obtained by the search is provided to the prediction / measure generation unit 44. The prediction / measure generation unit 44
Based on the set of data read from the accident database, the contents of possible accidents are obtained, and necessary measures are obtained based on the set of data read from the countermeasure database 22. The obtained content of the accident and the data corresponding to the necessary countermeasures are given to the image / form creation unit 30.
As a result, the content and countermeasures of the accident
32, or output from the output device 34 as a printed matter.

For example, the time of the accident includes a specific period such as the year-end and New Year holidays, a summer vacation, and a specific day of the week. The weather includes snow and rain. When desired conditions are set in this manner, the data classification / search unit 16 searches the accident database 18 and the countermeasure database 22 for data via the prediction / countermeasure generation unit 44 and the control unit 14, and sets a predetermined data set. Can be read out.

As described above, according to the present embodiment, various analyzes are executed by the analysis / evaluation unit 40 based on the data stored in the various databases, and a statistical graph or table is displayed on the screen of the CRT 32. Displayed or this is
It is obtained as a printed matter from the output device 32. The operator can obtain a desired analysis result by a simple operation of designating the analysis.

Further, according to the present embodiment, the diagnosis section 42
Thus, various evaluations such as evaluation of safety can be obtained. Further, according to the present embodiment, the prediction / measure generation unit 44 refers to past accidents stored in various databases and data on the countermeasures, and predicts possible accidents and measures for preventing the accidents. Generate
Therefore, the operator can be informed of an accident that can occur under conditions such as a predetermined time period (for example, New Year's holiday, summer vacation), a predetermined climate (snowfall, heavy rain) and the like, and
Necessary measures can be proposed.

Finally, other functions and operations of the safety management support system 10 according to the present embodiment will be described. In the safety management support system 10, when a responsible person is involved in an accident that has occurred or when a railway company and its affiliated companies include staff, data related to them is stored in an accident database, in particular. Is possible.

The data set (data related to the responsible person) composed of the data on the responsible person and the data set composed of the data related to the casualties of the staff (data on the casualties of the staff) are associated with the accident IDs and stored in the accident database. 18 are stored in predetermined areas. Hereinafter, input of characters and numerals corresponding to these data will be described.

In 10), enter predetermined letters and numbers. Here, for example, a button is added to the right side of the columns 2101 to 2105. When the operator picks a button using the mouse, the input device 12 notifies the controller 14 of the fact. The control unit 14 accesses personnel information and organization information stored in the facility information database 60 using a transmitting / receiving device (not shown), reads out necessary data,
Accept this. By giving this to the image / form creation unit 30, a pull-down menu including necessary information is displayed on the screen of the CRT 32. Thus, the operator inputs a character string using the keyboard, or selects a desired character string from a pull-down menu. As a result, it becomes possible to enter necessary information in the columns of the screen 2100. The entered information (character strings and numbers) is stored in the accident database 18 as the above-described responsible person-related data.

On the other hand, when the operator operates the mouse or the like to give an instruction to display a screen for inputting employee casualty data, the CRT 32 of the CRT 32 is transmitted via the control unit 14 and the image / form creation unit 30. The image shown in FIG. 22 is obtained on the screen. As with the input of the responsible person data described above, the operator inputs a character string using a keyboard, or selects a desired character string from a pull-down menu. Thus, necessary information can be entered in the columns of the screen 2200. The entered information (character strings and numbers) is stored in the accident database 18 as employee casualty data.

[0099] When necessary, the control unit 14 transmits the responsible person-related data and / or the casualty data to the facility information database 60 provided in the host computer via the transmission / reception device. It may be configured.

Further, in the safety management support system 10 according to the present embodiment, when the death or injury of an employee due to an accident is an occupational accident, it is possible to store data relating to the accident in the accident database.

When the operator operates the mouse or the like to give an instruction to display a screen for inputting occupational accident data, a CR is transmitted via the control unit 14 and the image / form creation unit 30.

A pull-down menu containing necessary information is displayed on the screen of (1). By inputting a character string using a keyboard or selecting a desired character string from a pull-down menu, the operator can enter necessary information in a column on the screen. The entered information (character strings and numbers) is stored in the accident database 18 and the countermeasure database 22.

The set of data on work-related accidents stored in the accident database is almost the same as the structure of the data set described with reference to FIG. However, instead of an accident ID for specifying an accident, a work injury ID corresponding to a work accident number for specifying a work accident is added. The data set stored in the countermeasure database 22 and showing details of the countermeasures for occupational accidents is almost the same as the structure of the data set described with reference to FIG. Also in this data set, a work accident ID corresponding to a work accident number for specifying a work accident is added instead of an accident ID for specifying an accident.

The control unit 14 may also be configured to transmit such data relating to occupational accidents to a facility information database of a host computer via a transmission / reception device (not shown). In addition, when the driving accident and the occupational accident correspond to each other, and as a result, the part of the data set (see FIG. 3A) related to the driving accident coincides with the part of the data set related to the occupational accident, The former may be copied to the latter, or the accident ID and the work injury ID may be associated with each other, and the latter may be omitted to reduce the necessary data amount.

Further, in the present embodiment, the number of occupational accidents per month, the number of occupational accidents, and a summary table of the number of occupational accidents are the same as those shown in the form (for example, summary list of occurrences, generalization table) shown in FIG. Can be output. These processes are almost the same as those described with reference to FIG.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, this is done.

For example, in the above embodiment, the safety management support system stores various data related to the railway accident in various databases, retrieves and outputs them, or converts the data into data. Although it is based on analysis, it is clear that the present invention is not limited to railway accidents, and that the safety management support system can be used to manage car accidents, accidents at construction sites, and the like.

Further, in the above-described embodiment, in the security management support system, it is possible to perform all of the retrieval of data stored in the database, output of forms, accident analysis, safety diagnosis, accident prediction, and formulation of countermeasures. In Although,
Obviously, the configuration may be such that only one of them can be executed.

Further, in the above embodiment, the security management support system is provided with four databases, which means storage devices (for example, hard disk devices) physically separated into four. It is apparent that they may be provided in one storage device.

In this specification, means does not always mean physical means, but also includes a case where the function of each means is realized by software.
Also, even if the function of one means is realized by two or more physical means, or the function of two or more means,
It may be realized by one means.
