Description

  The present invention relates to an apparatus for automatically creating an inspection table representing inspection points and inspection items of electric power equipment, and a network system using the apparatus.

  Generally, power facilities such as hydraulic iron pipes and gates managed by an electric power company are inspected regularly or temporarily. In the inspection of the equipment, inspection work such as visual inspection or data measurement is performed according to an inspection table indicating inspection points and inspection items, and the inspection result is recorded in an information terminal such as a personal computer as electronic data. If any abnormality is found during the inspection, the inspector takes an emergency measure and records that fact as special item data.

  Also, in actual inspection work, there are a large number of inspection points and inspection items, and the number of skilled workers in the inspection work is decreasing. May be overlooked due to carelessness or oversight of equipment when concentration is lacking. Therefore, the inspection work is performed with various ingenuity, such as two or more inspectors working together.

  For example, Patent Literature 1 below describes an elevator inspection item execution leakage prevention device that can reliably prevent inspection item execution leakage and maintain elevator quality. In this technique, when it is determined that there is omission of inspection, an alarm notifying that inspection is not completed is displayed on a dedicated terminal operated by the operator.

  However, as mentioned in the above document, when it is pointed out that the inspection is not performed after the inspection is completed, the concentration of the inspector may be lacking due to circumstances such as fatigue. There is a risk of overlooking. In consideration of such circumstances, it is desirable to be able to grasp precautions such as inspection items that are highly likely to be abnormal in the inspection work.

  It is an object of the present invention to provide an inspection table creation device and an inspection table creation system for causing an inspector to perform an inspection of equipment accurately.

  The inspection table creation apparatus of the present invention is an apparatus that automatically creates an inspection table representing inspection points and inspection items of electric power equipment, and information on which the inspection table is based and past inspection results of the electric power equipment A data storage unit for storing the inspection table, and an inspection table creation unit for creating an inspection table that highlights the inspection points and inspection items to be preferentially inspected based on the information and the inspection result .

  In the embodiment of the present invention, the inspection result is indicated by an evaluation score obtained by evaluating an inspection item of each inspection location based on a predetermined standard, and the inspection table creation unit is configured to check the inspection location and the inspection based on the evaluation score. By rearranging the items, the inspection points and inspection items to be preferentially inspected are made conspicuous.

  In another embodiment, the inspection table creation unit creates an inspection table based on the latest inspection result among the inspection results.

  As the electric power facility, a hydraulic iron pipe or a gate installed in a hydroelectric power plant can be targeted.

  The inspection table creation system of the present invention comprises an inspection table creation device installed on a network, and a terminal connected to the inspection table creation device through the network so that communication is possible. The inspection table is created based on a request from the terminal side and transmitted to the terminal side.

  According to the inspection table preparation apparatus of the present invention, an inspector is highly likely to have a location and item to be inspected preferentially, that is, an abnormality has occurred. Since it can be grasped in advance, the inspection work can be performed accurately. For example, by checking these cautions at the start of highly concentrated inspection, the inspection can be performed carefully so as not to overlook the presence of an abnormality.

  By creating an inspection table based on the latest inspection results in the past, it is possible to accurately grasp inspection locations and inspection items that are likely to be abnormal at the present time.

  In the conventional inspection work of hydraulic iron pipes or gates, the inspection table printed on paper was used, so the priority of inspection could not be known, and troubles such as overlooking an abnormal state when concentration was insufficient may occur. However, by using the inspection table preparation apparatus of the present invention, these troubles can be avoided and the inspection work can be performed accurately.

  According to the inspection table creation system of the present invention, an inspector carries a terminal equipped with an application such as an Internet browser capable of browsing an inspection table (for example, an Html [Hyper Text Markup Language] file), The inspection table required for the inspection work can be browsed, and the inspection work can be performed accurately. Even in this case, the location and items to be preferentially inspected, that is, the possibility of abnormality is high, and it is possible to grasp the precautions such as the locations and items to be inspected in advance and carry out the inspection work more accurately. it can.

  FIG. 1 shows the configuration of an inspection table creation device 1 of the first embodiment.

The inspection table creation device 1 automatically creates an inspection table representing inspection points and inspection items of a hydraulic iron pipe through which water for hydropower generation flows.
A data storage unit 3 for storing information such as inspection points and inspection items that are the basis of the inspection table, inspection methods for inspection items at each inspection point and other information necessary for inspection, and past inspection results for the above-mentioned hydraulic iron pipes,
An input unit (for example, a mouse and a keyboard) 5 capable of inputting appropriate information necessary for information processing performed by the inspection table creation device 1 such as information for specifying the inspection result and the hydraulic iron pipe to be inspected;
An inspection result registration unit 7 for storing the inspection result input from the input unit 5 in the data storage unit 3;
Based on information representing a specific hydraulic iron pipe input from the input unit 5, an inspection result search unit 9 that retrieves a past (for example, latest) inspection result for the hydraulic iron pipe from the data storage unit 3;
Based on the information that is the basis of the inspection table and the past inspection results retrieved, the inspection table that highlights the points and items that should be inspected preferentially among the inspection items for each inspection point of the hydraulic iron pipe that is the inspection target An inspection table creation unit 11 for creating
A display unit (for example, a liquid crystal monitor or the like) 13 for presenting the created inspection table;
When there is a request from the input unit 5 to output an inspection method for a certain inspection item or other information necessary for the inspection, the information is extracted from the data storage unit 3 and prepared by the inspection table preparation unit 11 An inspection information presenting unit 15 that is displayed on the display unit 13 together with or separately from the inspection table is provided.

  For example, as shown in FIG. 2, the past inspection results are mainly indicated by evaluation points (numerical values) that represent the state of each inspection item based on a predetermined standard, and are used as the basis of the inspection item. In the corresponding state, it is accumulated in the data storage unit 3 every time inspection is performed. This evaluation score represents that the larger the value, the greater the degree of abnormality found in the inspection item. In the figure, the total evaluation score is the total of the values obtained by subtracting 1 from each evaluation score, and the abnormality ratio is the value obtained by dividing the total evaluation score at each inspection location by the number of inspection items at each inspection location. . Also, in the special remarks, items noticed by the inspector at the time of inspection of each inspection point, such as precautions at the inspection of each inspection point, are input and recorded as inspection results. Evaluation criteria for inspection items will be described later.

  In actual inspection, since the number of inspection items to be inspected is different for each inspection location, a difference in weight is generated between the total evaluation points of each inspection location. For example, the total score of “Iron pipe-tube barrel” and “Iron pipe-joint-welding” is “1”, but the number of inspection items is “12” and “7”, respectively, and the number of inspection items is small. It can be said that “iron pipe-joint-welding” has a lower possibility of anomaly being found than “iron pipe-cylinder” and has a smaller weight. Therefore, simply comparing the total evaluation points cannot accurately identify the inspection location to be preferentially inspected, that is, the location that is more abnormal. Therefore, the influence of the difference in weight between the total evaluation points is eliminated by specifying the inspection points to be preferentially inspected based on the abnormality ratio. Further, by comparing the evaluation points of the respective inspection items, the inspection items to be preferentially inspected at each inspection location can be specified.

  As described above, the inspection table creation unit 11 identifies inspection points and inspection items to be preferentially inspected, and creates an inspection table that highlights these.

Specifically, in order to create the inspection table, the inspection table preparation unit 11
An inspection point sorting unit 17 that creates an inspection table in which inspection points (lines in FIG. 2) are rearranged based on an abnormality ratio of each inspection point in a predetermined (for example, latest) inspection result;
The inspection items (columns in FIG. 2) of the inspection table created by the inspection point sorting unit 17 are the evaluation points of the inspection points with the highest inspection priority, specifically the inspection points with the highest ratio. And an inspection item sorting unit 19 for rearranging and preparing an inspection table based on the above.

  FIG. 3 shows an example of the inspection table 31 in which the inspection points and inspection items are rearranged based on the abnormal ratio of each inspection portion and the evaluation points of the inspection items, and the points and items to be preferentially inspected are conspicuous. Indicates. In the first embodiment, the inspection points that should be performed as a series of work in the actual inspection work, for example, “iron pipe-joint—˜” are rearranged integrally, and further, the three places are rearranged. It was decided to do.

  The inspection table 31 is a table in which inspection locations and inspection items are associated with each other. The inspection locations are arranged from the top and the inspection items are arranged from the left in descending order of inspection priority. Also, at the right end of the check table 31, a special note entry field 33 is provided for an inspector to input special notes.

  In the inspection table 31, an inspection column 35 indicating a location and an item to be inspected is displayed in white, and a blank space 37 indicating a location and an item not to be inspected is colored and an evaluation score is input only in the inspection column 35. can do. In addition, an inspection information display button 39 is provided at the upper right of each inspection column 35. The inspection information display button 39 can be displayed by operating the input unit 5 and clicking on the display unit 13 to present the inspection method and other information necessary for the inspection. It has been. When this button 39 is clicked, the inspection information presenting unit 15 displays information on the inspection item corresponding to the column, superimposed on the inspection table 31 or side by side with the inspection table 31. Information presented by the inspection information presentation unit 15 will be described later.

  FIG. 4 is a flowchart of software for causing an information processing apparatus such as a computer to operate as the inspection table creation apparatus 1. The information processing by this software will be explained along with the actual inspection work of a hydraulic iron pipe.

  The inspector of the hydraulic iron pipe carries the inspection table preparation device 1 having the above-mentioned software installed on the notebook computer to the inspection site, and operates the input unit 5 to identify the inspection result regarding the hydraulic iron pipe to be inspected. And the information which specifies the predetermined | prescribed (for example, the newest) thing among the said inspection results is input. Based on this information, the inspection result retrieval unit 9 takes out the corresponding inspection result from the data storage unit 3 (step [hereinafter referred to as ST] 1) and sends it to the inspection table creation unit 11.

  The inspection location sorting unit 17 of the inspection table creation unit 11 creates an inspection table in which inspection locations (rows in FIG. 2) are rearranged based on the abnormal ratio of each inspection location in the searched inspection result (ST2). The inspection item sorting unit 19 rearranges the inspection items (column in FIG. 2) of the inspection table created by the inspection point sorting unit 17 based on the evaluation points of the inspection items of the inspection points with the highest inspection priority. An inspection table 31 (FIG. 3) is created (ST3) and displayed on the display unit 13 (ST4).

  The inspector performs the inspection in order from the inspection item of the inspection place with the highest priority according to the inspection table 31 displayed on the display unit 13. At this time, if you want to know information such as the inspection method, evaluation criteria, and special remarks regarding the inspection location regarding the item to be inspected, by clicking the inspection information display button 39 in the upper right of the inspection column 35 of the inspection table 31, An inspection information display request message is transmitted (the determination result of ST5 is “inspection information display request”). On the other hand, when all the inspection items have been inspected, a message indicating that inspection has been completed and the inspection result should be registered, such as an end button (not shown) displayed on the display unit 13, is transmitted. By clicking the button, an inspection result registration request message is transmitted (the determination result of ST5 is “inspection result registration request”).

[When the determination result of ST5 is “Display request for inspection information”]
When the inspection information display request message is input, the inspection information presenting unit 15 refers to the inspection result (FIG. 2) in the past (here, the latest) and the evaluation criteria table shown in FIG. An inspection method, evaluation criteria, and special notes regarding the inspection item of the place are extracted (ST6). The evaluation criterion table is composed of a plurality of records in which data corresponding to the fields of inspection points, inspection items, inspection methods, evaluation points, and evaluation criteria are input, and is stored in the data storage unit 3. In a database such as an evaluation criteria table, vertical items such as inspection locations and inspection items are called fields, and horizontal rows formed by inputting data into each field are called records. A file such as an evaluation criteria table is composed of one or more records.

  When the inspection information presentation unit 15 extracts the inspection method, the evaluation criteria, and the special notes, the inspection information is presented as inspection information on the inspection table 31 as shown in FIG. 6 (ST7), and the determination of ST5 is performed again. The inspector can perform an accurate inspection based on the inspection table 31 and the presented inspection information.

[When the determination result of ST5 is “Registration request for inspection result”]
When the inspection result registration request message is input, the inspection result registration unit 7 has inspected all the inspection items in the inspection table 31 of the inspection table 31, that is, whether the evaluation points have been input in all the inspection columns 35. Is determined (ST8).

  If the determination in ST8 is “NO”, that is, if there is an omission of an evaluation score in one or more inspection fields 35, an error message indicating that the inspection has not been completed is displayed on the display unit 13 (ST9).

  On the other hand, when the determination of ST8 is “YES”, that is, evaluation points have been input in all the inspection fields 35 and it is determined that the inspection has been completed, evaluation points for each inspection point are based on the input evaluation points. The sum and the abnormal ratio are obtained (ST10). After obtaining the evaluation score total and the abnormality ratio, the inspection result registration unit 7 stores the inspection result including the evaluation score, the evaluation point total, the number of inspection items, the abnormality ratio, and the special notes in the data storage unit 3 ( ST11), a series of information processing by the software stored in the inspection table creation device 1 is completed.

  By using the inspection table preparation apparatus 1 of the first embodiment at the inspection site, points and items to be preferentially inspected, that is, there is a high possibility of abnormality, and notes such as points and items to be inspected with caution Therefore, it is possible to accurately perform inspection work. Specifically, for example, by grasping these precautions at the start of inspection with high concentration, it is possible to perform the inspection work carefully so as not to miss the presence of an abnormality.
