Description

Detailed Description of the Invention [Industrial applications]

[0001] The present invention relates to a patrol support system using a handy terminal most suitable for use in maintenance management services for various facilities and equipment.

[0002]

2. Description of the Related Art As is well known, in various facilities and equipment, service personnel regularly or irregularly patrol (pay) to perform maintenance management and maintenance services. Conventionally, for such patrol work, a checklist in which check items are displayed in advance or a handy terminal in which these check items are stored in an IC memory is always carried by a service person, and the facility / facility at the service site. After entering or inputting the check results of the above into these media, the centralized centralized management of the check results in a management system that prevents check failures and equipment failures from occurring.

[0003]

By the way, the following problems exist in the above-mentioned conventional patrol work. First, if you want to centrally maintain multiple facilities,
It is desirable to register a patrol item file in which patrol items (patrol points, check contents, etc.) are created / edited for each patrol target in advance in a database. However, when the facilities and equipment to be inspected are diverse, even if the inspection target is categorized into some basic configuration patterns in advance, there are many cases where the detailed device configuration and the inspection content are different.

Even if there is a difference in the details of the structure, it is naturally impossible to use the same inspection item file because the inspection contents are different. Therefore, the database is rebuilt for each facility. Must be,
This requires a great deal of time and labor. In addition, there is a case where the equipment is changed after the dedicated database is created and the contents of the database must be changed again.

In view of the actual inspection work, it is not always necessary for a person who is familiar with the work to perform it, and a beginner with little experience may perform it. Therefore, when creating a check sheet or guidance display contents for a handy terminal for beginners, it is necessary to consider, for example, setting each inspection item in order of inspection route in order to prevent omission of checks. However, in such a case, it is possible that the check contents become redundant to the expert, the time required for the work becomes long, and as a result, the work efficiency is lowered. On the other hand, if you set the check contents according to the expert, beginners will not know what to do, and it will be easy for check omissions to occur.
It reduces the reliability of patrol work.

As described above, in the conventional patrol work, although the rough basic structure of the patrol target is the same, in many cases, there are differences in details such as facilities and devices, and therefore, it differs for each patrol target. Since it is necessary to prepare a check sheet, etc., there is a problem that it is difficult to create a database of patrol items and patrol results according to these patrol items.
There was a problem that it was not possible to perform patrol work according to the level of proficiency of the patrol. Furthermore, as the number of inspection targets increases and the number of inspection points increases, it becomes difficult to centrally manage inspection data, and it becomes difficult to perform efficient maintenance maintenance. The present invention has been made in view of the above-mentioned circumstances, and an inspection item,
It is an object of the present invention to provide a patrol support system that can easily make a patrol result database and can perform patrol work according to the proficiency level of a patrol person and enable efficient maintenance management.

[0007]

The present invention provides a database in which a plurality of basic configuration patterns to be inspected are registered, and the inspection contents for each of the basic configuration patterns are previously edited and stored, and the database. After selecting the basic configuration pattern of the scheduled inspection target from, the inspection item editing means for individually changing the details of the inspection content in the database, and the inspection item editing means, Numerical item editing means for editing numerical items of equipment to be patroled, route order item editing means for editing input items of patrol data, and selection item editing means for hierarchically editing input items of the patrol data. At least, the patrol item edited by the patrol item editing means is stored in the handy terminal, and then the guidance is provided in the handy terminal. It collects patrol data locally in accordance inspection items shown, after patrol completed, to transfer these inspection data to the central processing unit, it is characterized by aggregating processed collectively.

[0008]

According to the above-mentioned invention, a database is prepared in which a plurality of basic configuration patterns to be inspected are registered, and the contents of inspection for each of the basic configuration patterns are edited and stored in advance. After the basic configuration pattern of the scheduled object is selected and designated, the inspection item editing means individually changes the details of the inspection contents in the database. In addition, after editing the numerical items of the inspection target equipment in the inspection target by the numerical item editing means in the inspection item editing means and hierarchically editing the inspection items randomly selected by the inspection person by the selection item editing means. The route order item editing means edits the input items of the inspection data in the route order. Furthermore, after the patrol is over, the patrol data collected at the handy terminal is collectively processed by a personal computer to create a patrol database.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. The target of the patrol support system of the present invention covers various fields such as maintenance management of industrial plants and maintenance of building facilities. In the following description, an example in which the patrol work of a substation is applied will be described.

A. Overall Configuration FIG. 1 is a block diagram showing the overall configuration of a patrol support system. In this figure, reference numeral 1 denotes a device carried by a patrol person at the time of patrol, which is a mobile terminal device (handy terminal) to which patrol items are displayed and check data is input. Reference numeral 1a is a CPU that controls each part of the handy terminal 1. The operation of the system will be described later. Reference numeral 1c is, for example, an IC memory card, and the inspection items of the substation to be inspected are downloaded in advance from the inspection item file in the database to the IC memory card 1c.
Further, the inspection result input for each inspection site and inspection item is written in the IC memory card 1c by the CPU 1a.

Reference numeral 1b is a ROM in which a system program of the handy terminal 1 is stored, and 1f is a RAM in which a patrol program and the like are stored and which is always backed up by a battery. Reference numeral 1d is a display device such as an LCD, which is a device for displaying various data supplied from the CPU 1a via an internal bus. Reference numeral 1e designates an operator composed of a transparent touch panel arranged on the display device 1d, a ten-key pad, etc., for generating an operator signal corresponding to each operation, and for the above-mentioned inspection result input, This operator 1e is used.

The IC memory card 1c is detachable from the handy terminal 1, and is detached after the inspection is completed and attached to the card interface 2. 3 is a personal computer as a central processing unit
This personal computer 3 edits and creates the inspection items under the memory operation of the IC memory card 1c and the system operation described later, and uploads the inspection data stored in the IC memory card 1c. , Register it in the database. An external storage device 4 is composed of, for example, a magnetic disk device. This external storage device 4
The configuration pattern, which has been categorized into several types, and the inspection items corresponding thereto are stored in the table, and the information supplied from the personal computer 3, that is, the inspection data read from the memory card 1c and the updated items. Items and the like are stored. The CRT display 5 displays various information from the personal computer 3.

Next, the functions of the handy terminal 1 and the personal computer 3 having the above-mentioned configurations will be described in detail with reference to FIG. Functions of personal computer 3 The personal computer 3 functions Mf1 to Mf according to the control program.
Embody f4. Mf1 is a function Mf2 to Mf described later.
This is a menu function for selecting any one of the four. Next, the substation definition function Mf2 includes a plurality of configuration patterns of inspection targets registered in advance in the database of the internal or external memory as inspection item files, that is, a plurality of configuration patterns representing the configuration of each inspection target facility. This is a function to change the type, model, etc. of equipment after extracting the configuration pattern of the specific target from within.

Here, the updated inspection item is updated and registered in the inspection item file of the database. In this way, a basic configuration pattern corresponding to various equipment configurations should be prepared in advance as a database. Then, it becomes possible to update the database so as to exactly match the target inspection target equipment and easily create a new inspection item.

Next, the inspection item editing function Mf3 individually edits (corrects) the inspection item created by the function Mf2. Although this function Mf3 has the same basic configuration pattern, it actually has some equipment configuration,
Since there are many cases where the inspection contents are different, it is for correcting the inspection item in response to such a case, and more specifically, the numerical value for editing and specifying the numerical item of the inspection target equipment in the inspection target. Item means, route order item editing means for editing and designating the input items of the inspection data in route order, and selection item editing means for hierarchically editing and designating the input items of the inspection data, and further adopted as necessary. It is realized by means for editing confirmation items at the time of the end of the inspection, and by using it in combination with the above function MF2,
It is possible to efficiently create different inspection items for each substation. The edited result is registered in the external storage device 4 as the inspection item file F1.

Next, as described above, the patrol database function Mf4 reads the patrol result file F2 stored in the IC memory card 1c of the handy terminal 1 after the patrol, and patrols the external storage device 4 with this. It is registered as the database F3, and if necessary, the inspection item is used as a keyword to search the database for a desired inspection result, sort the inspection results in a sorted order, or perform processing such as data graphing.

Functions of Handy Terminal 1 The Handy Terminal 1 displays a screen corresponding to a conventional check sheet under the operation of the patrol program Pf.
In addition, the inspection result input according to this screen display is I
It is written in the inspection result file F2 of the C memory card 1c.

B. General Operation Next, the general operation of the system according to the embodiment will be described with reference to FIGS. Here, first, the inspection item creation / editing on the personal computer 3 is shown, then, after explaining the operation of the handy terminal 1, the inspection result of the personal computer 3 based on the inspection result collected by the handy terminal 1 is displayed. Database creation will be explained.

(1) Operation of personal computer 3 Substation defining operation When the personal computer 3 is started, first, an initial menu screen (not shown) is displayed. In this menu screen,
When the operator selects the substation definition function and selects a desired configuration from among several modeled substation configurations, the substation definition unit of the system uniquely identifies the substation type. , The morphology is determined. The personal computer 3 extracts a compatible configuration pattern from a plurality of basic configuration patterns registered in the database and displays it as a skeleton diagram in the display area G1 in the substation definition setting screen D1 shown in FIG. To do. On this screen, the substation name; IP1, and the basic configuration pattern of the substation (substation type; IP2, substation form; IP3) can be modified as necessary. In addition, in this example, a single-line connection diagram of a two-line power receiving form is displayed as a substation configuration pattern corresponding to a designated input.

Thus, in the initial state of the function Mf2,
The basic structure of the equipment to be visited is displayed graphically. Here, if it is necessary to change the configuration model etc. according to the target substation equipment, specify the icon of the device type in the lower right of the screen, and a window screen (not shown) showing another model, model, name, etc. ) Opens, and by specifying specific data in this window screen or by inputting data, the initially configured model etc. is changed. Even if the equipment configuration model is changed as described above, new inspection items and inspection contents after the change are prepared, so just by changing the configuration model etc., the corresponding part of the original inspection item file Is re-edited and a new patrol item file is completed.

Inspection item editing operation By the way, in the above-mentioned substation defining operation, the change of the equipment model and the like was targeted. However, when a detailed change of the inspection contents is requested, this inspection item editing operation is performed. To function. This inspection item editing operation is realized by the inspection item editing means of the system, and more specifically, the numerical item editing means for editing the numerical item of the inspection target equipment in the inspection target, and the input item of the inspection data. Order item editing means for editing the route order, a selection item editing means for editing the input items of the inspection data in a hierarchical structure, and an item to be checked at the time of exit when the inspection is completed It is realized by four means.

For example, the numerical item editing is realized by the numerical item editing means, and when the numerical means is designated, the numerical item editing screen D2 shown in FIG. 4 is displayed on the display 5. In this example, a screen for numerically inputting the "gas pressure" is shown. The screen D2 is divided into a main screen of the display area G2 and a sub-screen of the display area G3. The display area G2 is used for editing numerical items, and is a “unit” of the numerical value read at the time of patrol and read. Warning conditions such as specification of calculation formulas such as “temperature correction coefficient” for numerical values or upper and lower limits of “control value” that is a criterion for abnormality are defined as necessary. Here, when the editor newly defines a “correction coefficient”, a management value, and the like according to the device to be inspected, the numerical items displayed in the display area G3 are changed accordingly.

The display mode of the display area G3 is as follows.
As will be described later, the layout is the same as the input screen for the numerical items of the handy terminal 1. Therefore,
By editing while referring to this display area G3, it becomes clear at a glance how the item being edited is displayed on the handy terminal 1. The editing result made in this way is reflected in the inspection item file F1 and the corresponding inspection item is updated and registered.

Further, the selection item editing for hierarchically editing the input items of the inspection data is realized by the selection item editing means, and when the means is designated, a selection item editing screen (not shown) is displayed. This screen is divided into the display area of the main screen and the display area of the sub-screen, and the display area of the sub-screen is the same as in the case of editing numerical items.
Since it is the same as the display screen of No. 1, it is obvious by editing while referring to the display area of the sub screen how the item being edited is displayed on the handy terminal 1.

Here, the meaning of hierarchically editing is as follows.
For example, as shown in FIG. 5, the inspection target equipment is classified into a large classification (a rough model classification), a middle classification (a device classification in the vertical direction of the connection diagram), and a small classification (a detailed check point). This is to edit by classifying according to the size of the classification, and it is clear to the experienced practitioner that performing the inspection work while specifying each classification in this way is extremely efficient. The edited result obtained in this way is reflected in the inspection item file of the database, and the corresponding inspection item is updated and registered. Further, even when the route order item editing for editing the inspection route and the input items of the inspection data in advance in the route order is designated after the selection item editing is completed, the same screen configuration as that described above is obtained by the route order item editing means. The route order item edit screen is displayed, and the edit work is performed in the same process.

The edited result obtained in this way is reflected in the inspection item file of the database and the corresponding inspection item is updated and registered in the same manner as described above. Finally, if necessary, edit the check items for exit and edit the check items for exit (gate, key status, etc.) at the end of the patrol in the same procedure as above, and edit this. Register the result in the patrol item file. The patrol item editing is realized by the above four means.

(2) Operation on the handy terminal 1 side When starting a patrol, first, the patrol item file F1 edited / created on the personal computer 3 side is prepared exclusively for each patrol target (substation). IC memory card 1c
To download. Next, at the inspection location, when the inspection person turns on the power of the handy terminal 1 equipped with the IC memory card 1c to start the inspection program, the inspection item file F1 is read and the inspection items are displayed as guidance. go.

As explained in the operation on the side of the personal computer 3, in the handy terminal 1, a patrol item can be randomly selected in order to patrol according to the work level and know-how of the patrol operator and to improve work efficiency. The screen for inputting the above-mentioned selection items that was edited in the above, and so that inspection leaks are unlikely to occur, so that even beginners can realize highly reliable work,
A screen is provided for inputting route order items in which the inspection items are displayed in the order of the inspection route.

FIGS. 5A to 5B show an example of a screen for inputting selection items, in which the patrol observer hierarchically sets the input items from large classification to small classification according to the situation of the substation. The display screens required for random selection are shown. First, in the screen PT1 of FIG. 5 (a), as a large classification screen of the substation equipment, a circuit breaker, a breaking path, etc. are displayed as a rough type of equipment. When (touched), the transparent touch panel provided on the display screen 1d generates an operation signal corresponding thereto, and the CPU 1a detecting this operation signal switches the display screen to the screen PT2 shown in FIG.

The screen PT2 is a middle classification input screen in which the devices are classified in the vertical direction with respect to the connection diagram, and one of the displayed "transformers # 1B to # 3B" is selected. Next, on this screen PT2, for example, when an observer presses the point P2, the small classification screen PT shown in FIG.
3 is selected, and on this screen PT3, a detailed check location in "transformer # 2B", that is, any one of "control panel", "tap switching device" and "other" is selected.

After the above work, more detailed inspection items (not shown) are displayed, and the inspection result is input in accordance with the guidance display on this screen. As described above, since all the patrol work by the handy terminal 1 is touch panel guidance input, all patrols can be performed without referring to the chuck sheet or the work manual.

Next, FIG. 6 is a diagram showing display screen examples PT4 to PT6 at the time of inputting the above-mentioned numerical items. Screen PT5 is displayed after selecting an input item on screen PT4.
Enter a numerical value in PT6. As shown in this example, in the numerical value input screen displayed on the handy terminal 1, reference to the numerical value input in the previous patrol (previous value displayed on the screen PT6) and correction automatically calculated based on the input value It realizes a function of improving reliability of input work such as displaying a value or sounding a warning sound (for example, a beep sound) under a predetermined condition. Furthermore, in consideration of the fact that the data collection interval is different for each inspection item, the interval of inspection work can be appropriately selected.

And in this handy terminal 1,
When the patrol person performs the patrol work based on the display screen and completes the input of the confirmation items at the time of the termination of the patrol, the series of patrol results are displayed as the patrol result file F2 of the IC memory card described above.
Register with. When all inspection work is completed, the IC memory card 1c is removed from the handy terminal 1, this is set in the card interface 2, and the inspection data is transferred to the personal computer 3.

(3) Operation on the side of the personal computer 3 (making a database of patrol results) The personal computer 3 with the memory card 1c set in this way
Activates the above-described inspection database function Mf4 in accordance with the operator's instruction to create a database, and the inspection result is merged with the inspection result before the previous time as necessary. The databased patrol result is subjected to known processing such as extraction processing based on a predetermined keyword, search processing, or sorting. Here, it is important to note that conventionally, different check sheets were used for each facility, so that the vocabulary or expressions of the inspection items could not be unified. However, according to this embodiment, it is possible to unify the inspection items because the inspection items corresponding to each equipment configuration are created / edited in a unified manner.

As described above, in this embodiment, the personal computer 3 centrally creates the inspection items corresponding to each substation facility, so that even if there is a difference in the facility configuration, a uniform expression, or You can set patrol items by vocabulary. Therefore, it is possible to easily make a database of each inspection result using the unified inspection item as a keyword. in addition,
Since the handy terminal 1 that is carried in patrol work can select and display patrol items hierarchically structured according to the level of patrols and patrol items in the order of routes,
It is as if patrol work using a check sheet according to the level of proficiency of the patrol. By doing so, the skilled worker is urged to improve the work efficiency, while the inexperienced beginner contributes to the improvement of the reliability of the inspection work. Further, since the handy terminal 1 uses guidance input by operating the touch panel, it is an extremely easy input operation.

The IC memory card 1c described above is
It is practical that a plurality of memory cards are used and the inspection item files F1 corresponding to different equipment configurations are registered in these cards, and the memory cards of the handy terminal 1 are sequentially replaced to patrol a plurality of equipment. However, it is of course possible to exchange the data of one card and share the card. Furthermore, in the above embodiment, the memory card 1c is replaced to share the data between the personal computer 3 and the handy terminal 1. However, instead of this, for example, both are equipped with input / output ports, It is also possible to share each other's data by transferring the data via.

[0037]

As described above, according to the present invention, a plurality of basic configuration patterns to be inspected are registered, and the inspection contents for each of these basic configuration patterns are created / edited in advance. Is prepared, it is possible to collectively create inspection items for each inspection target by selecting a basic pattern of inspection target from the configuration patterns stored in this database and only slightly modifying the equipment type or the like. Further, the present invention provides a numerical item editing means, a route order item editing means for editing and specifying the input items of the inspection data in the route order,
It is equipped with a selection item editing means for hierarchically editing and designating the input items of the inspection data, and a patrol item editing means which is adopted as necessary and includes a confirmation item editing means at the time of leaving when the inspection ends. By the numerical item editing means, it is possible to create a selection item input screen in which the inspection items can be randomly selected and input according to the skill level for the expert, and by the route order item editing means, a beginner's inspection leakage can be prevented. Since it is possible to create a screen for inputting route order items that can prevent problems and realize highly reliable work, you can individually change the details of the inspection items in the inspection database and select different inspection items for each inspection target. In addition to being able to create efficiently, it becomes possible to create the inspection item file according to the inspection skill level of the inspection person, so that efficient inspection work can be performed. . Furthermore, since this handy terminal uses guidance input by operating the touch panel, it is easy to input the inspection data, and the inspection data can be collectively processed by the PC to create the inspection database.
