Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patrol inspection system suitable for patrol / inspection of substation equipment such as a substation, and particularly to a patrol inspection provided with a dictionary database in which terms used in patrol inspection items are registered. Regarding the system.

[0002]

2. Description of the Related Art As power is indispensable in modern society and blackouts are often a social problem, the demand for stable power supply is expected to increase in the future.

In addition, with the recent increase in the demand for electric power, 27
Gas insulated switchgear and air-insulated equipment with high voltage and large capacity of 5KV and 500KV have been added to conventional substations.

FIG. 10 shows a plan view of an example of such a general substation, which is a 500 KV gas insulated switchgear A, 500 KV / 275 KV transformer B, 275 KV air insulated switchgear C, 275 KV / 66 KV. Transformer D, 6
A 6KV air insulated switchgear E is provided.

However, when an accident occurs in such substation devices A to E, the effect thereof may be extremely serious. Therefore, the precursory phenomenon before the accident is caught in advance and the accident It is extremely important to prevent the occurrence.

[0006] Therefore, in the substation, a patrol / inspection is generally performed once a month or a few months in the past, and various data regarding each device are collected to determine whether or not there is an abnormality. ..

[0007] In other words, patrols at such substations
The inspection work is carried out by patrol staff carrying a record table that records the state of the equipment, various data, etc., and sequentially turning around each equipment in the substation premises.

[0008]

However, such a conventional patrol inspection system has the following problems.

That is, when a patrol / inspection work is performed in a substation as shown in FIG. 10 based on a conventional patrol / inspection system, the amount of inspection data becomes enormous because the number of constituent devices is very large. , It takes a lot of time to organize them.

Further, although the inspection work is carried out in accordance with a fixed inspection inspection route, inspection omission may occur, and it is not always easy to perform highly accurate inspection / inspection work.

Furthermore, when comparing the collected inspection data with past data, it is necessary to return to the office or central monitoring center from the inspection site and check the binder etc. in which the record list of past data is stored. Therefore, the efficiency of inspection and inspection work is not always high.

Furthermore, for this purpose, during patrol inspection, information about the substation equipment is input to a portable computer and stored in a database, so that the equipment status of all substation equipment can be monitored and confirmed, and patrol records can be recorded. It is necessary to improve the efficiency of daily work at substations, such as the creation and storage of tables. In such a patrol inspection system, inspection items along a certain patrol inspection route must be entered in the database in advance.

However, as shown in FIG. 11, the inspection items of the substation include a plurality of models for one line, and a plurality of inspection items for the one model.

Furthermore, one inspection item is often common to a plurality of models, and one line is often common to a plurality of models. In order to freely set the order of these inspection items, all the inspection items must be independent of each other, and one inspection item must have all the information on the model, line, and inspection item. That is, since the same terms such as model name and line name are used many times, there is a complication that the same terms must be keyed in many times when the database is input.

Further, when changing the term, all the places recorded by the term must be searched and changed, which is very complicated and is not changed if the search is forgotten. There is a possibility that the old term will remain as it is, and an inaccurate database will be used for patrol inspection. Furthermore, the same term is registered in many places, which causes the database to become large.

Therefore, the present invention has been made in consideration of such circumstances, and its purpose is to improve the work efficiency at the time of creating a database of patrol inspection items and to establish a reliable database. It is to provide a highly observable inspection system.

[0017]

[Means for Solving the Problems] The present invention is configured as follows to achieve the above object.

That is, the present invention comprises a portable computer for inputting and recording the inspection inspection data obtained according to the inspection inspection items for the inspection inspection target, and a host computer which receives the inspection inspection data from the computer and creates a database. The patrol inspection system has a dictionary database in which the terms used in the patrol inspection items are independently registered in the dictionary.

[0019]

[Function] Since the terms used for inspection items such as models and lines are registered in an independent dictionary database for each term, when creating a database of inspection items, complicated input of these terms or The change work can be minimized, and the work efficiency of the database creation can be improved.

Further, it is possible to prevent the names of the inspection items from being different among a plurality of inspection / maintenance personnel, an accurate database can be constructed, and the standardization of the names of the inspection items can be promoted.

[0021]

Embodiments of the present invention will be described below with reference to FIGS.

FIG. 2 is a perspective view showing the configuration of an embodiment of the present invention. In the figure, the patrol inspection system 1 allows a portable computer 2 to freely communicate data with a host computer 4 via a communication cable 3, And it is detachably connected.

The portable computer 2 is a target of inspection inspection, for example, it is carried by an inspection inspector who goes around the substation premises in accordance with the inspection route, and is obtained by inspection of each substation equipment by the inspection inspector. It has a key input unit 5 for inputting inspection inspection data and the like, a screen 6 for displaying the input data and the like, and a communication interface 7 for data communication.

On the other hand, the host computer 4 is installed in an office of a substation or a central monitoring center, etc., and transmits a database of patrol items registered in the patrol order to the portable computer 2 before patrol, and the patrol ends. The data transmitted later from the portable computer 2 is accumulated and created in the database.

In addition, in the inspection inspection system 1, the maintenance inspection personnel themselves set the inspection item name and inspection route in advance by the high-level computer 4
By inputting into, a means for appropriately setting the inspection item name and inspection route is provided.

Moreover, the inspection item names and inspection routes installed in the host computer 4 are stored in a memory or the like by transmitting them to the portable computer 2 before the patrol, for example, during the patrol inspection. On screen 6 of
The inspection item names are sequentially displayed according to the patrol route. The maintenance staff can surely prevent inspection omissions by sequentially patrol according to the items displayed on the screen 6.

The features of this embodiment reside in the dictionary database of the host computer 4 and the method of inputting check items in the host computer 4, which will be described below.

As the dictionary database, a model database, a line database, an inspection item database, a master database and a selector database are independently provided.

The model database is first created by maintenance personnel in order to register the model name. The model names entered in the model database are automatically numbered sequentially. To be done. This is for example model N
It is called O (number). FIG. 3 shows an example of a screen display when the model database is input by the host computer 4.

Further, when the maintenance staff inputs the line database in which the line names are registered, the input line names are also automatically numbered sequentially. This is called line NO, for example. FIG. 4 shows an example of the input screen of the line database.

Similarly, FIG. 5 shows an example of an input screen of the inspection item database to be entered by the maintenance personnel, and the number attached to the inspection item name is called, for example, inspection item NO. here,
For the data type, specify whether the inspection item is a numeric input or a selector input. That is, when the data type is "numeric type", the inspection item is a numeric input, and when "selection" + positive number, it is an input by the selector, and the positive number corresponds to the record of the selector database. .. The selector combination to be used is registered in the selector database, and the number combination to be used is registered in the data type.

FIG. 6 shows an example of the input screen of the selector database. At this stage, a dictionary database in which the model name, line name, inspection item and its data type are registered is created. Next, these are combined to enter a master database for inputting inspection items in the order of patrol. Examples of this master database input screen are shown in FIGS.

FIG. 7 is a model selection screen. The contents of the model database are displayed in the window on the right side of the screen, and one of them is highlighted as shown by the broken line box in the figure. The maintenance staff can move the highlighted display position by operating the up and down arrow keys of the host computer 4 and select the highlighted model with the input key.

When a model is selected, the selected model name is displayed on the input line of the screen, and the contents of the line database are displayed in the window on the right side of the drawing as shown in FIG. The maintenance personnel can select the line only by operating the up and down arrow keys and the input key, as well as selecting the model name. The selected line name is displayed on the input line at the bottom of the screen, and as shown in FIG. 9, the contents of the inspection item database are displayed in the window on the right side of the screen.
Furthermore, when inspection items are selected by the same method, a combination of model, line, and inspection item is determined and registered as one inspection item in the master database.

Further, as shown in FIG. 1, the information on the model, line, and inspection item registered in the master database is registered by model number, line NO, and inspection item NO, respectively.

Therefore, according to this embodiment, first, when inputting inspection items in the order of patrol, the maintenance staff constructs the database by only operating the arrow keys and the input keys of the key input unit 5 of the portable computer 2. Therefore, the efficiency of the data input work can be improved.

Secondly, since the terms used for inspection items such as models and lines are registered in an independent dictionary database for each term, these terms are frequently input when creating the inspection inspection database. Or the change work can be minimized.

It is also possible to prevent the names of inspection items from being different among a plurality of maintenance and inspection personnel.
In addition to being able to build an accurate database, it is possible to promote standardization of the names of inspection items.

Third, the master database is model N
O, line No., check item No. are registered, so when the model name, line name, check item, etc. are changed, only the corresponding database and the corresponding record need be changed. It is a normalized database design without the need to change the entire database. Therefore, the time required for the change can be suppressed to a minimum, and the forgetting of the change can be prevented, so that the correct database can always be maintained.

Fourthly, by using the dictionary database and the master database, the capacity occupied by the database can be significantly increased as compared with the database in which the model name, line name and inspection item name are directly registered as shown in FIG. It can be reduced.

[0041]

As described above, according to the present invention, since the terms frequently used for the inspection items such as the model, the line, and the inspection item are registered in the independent dictionary database for each term, the inspection item is input. The efficiency of the work, the standardization of terms, the normalization of the database, the downsizing of the database can be achieved together, and the accurate database can be constructed, so that the reliability of the inspection inspection can be enhanced.
