Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inspection support system for supporting inspection work for maintenance of facilities and equipment, and more particularly to inspection work such as patrol inspection and repair inspection carried out in an electric substation. The present invention relates to an inspection support system useful for providing assistance.

[0002]

2. Description of the Related Art Conventionally, inspection work for maintenance of facilities and equipment includes patrol inspection and repair inspection. The patrol inspection is an inspection work performed by the patrol member by visually checking the instruments and the general condition of the inspection object, and the repair inspection is an inspection work performed by the repair member disassembling the inspection object. As described above, since the repair inspection is a more troublesome inspection work than the patrol inspection, it is not performed as frequently as the patrol inspection. For example, when the equipment to be inspected is an electric station, patrol inspection is performed about twice a month, and repair inspection is performed once every several months to one year.

[0003] The work process of the patrol inspection and the repair inspection is performed by a skilled worker based on an inspection manual that defines an inspection item and an inspection method for each inspection object. For example, in the case of a patrol inspection, the patrol member compares the numerical values of each instrument of the inspection target with a judgment reference value that has been determined in advance, and inspects the general status of the inspection target to determine whether there is an abnormality sign of the inspection target. Judgment was made, and the inspection results were entered in a paper form carried during inspection work.

However, in such a patrol inspection, there is a problem that the criteria for judging abnormal signs are different for each patrol member, and recently, the inspection work has become difficult due to an increase in equipment to be inspected and complication of the equipment. This has led to a shortage of skilled workers. For this reason, an inspection support system including a portable terminal such as a portable computer is applied in order to quantitatively determine the presence or absence of an abnormality sign of the inspection object.

FIG. 5 is a block diagram showing a conventional inspection support system 30. As shown in FIG. The inspection support system 30 supports inspection work by inputting inspection data to a portable terminal 31 such as a portable computer and collecting data, and displaying an inspection method. The mobile terminal 31 includes an input unit 32 and an output unit 33 for various data, and the inspection object 3.
4 is provided with state determination means 35 for determining the state of No. 4, various data storage means 36, and data transfer means 38 capable of transferring various data between the upper terminal 37.

In the procedure of the inspection work to which the inspection support system 30 is applied, first, various data for supporting the inspection work are transferred from the upper terminal 37 to the storage means 36 of the portable terminal 31 (arrows A and B). Then, the worker 39 recognizes the state data of the inspection object 34 (arrow C) and inputs it to the portable terminal 31 by the input means 32 such as a keyboard (arrow D). The portable terminal 31 determines the presence or absence of an abnormal sign (arrow E) by the state determination unit 35 stored in the storage unit 36 based on the input state data, and outputs the state determination result to an output unit 33 such as a monitor. (Arrow F) to notify the worker 39 of the state determination result (arrow G). In addition, the storage means 36 of the portable terminal 30 stores data similar to a conventional inspection manual or a paper form as various data, and also displays an image of the inspection object 34 and its inspection items and inspections on a monitor as the output means 33 during the inspection work. By outputting the method, etc., the inspection work is supported. After the inspection work, the inspection data is migrated from the portable terminal 31 to the upper terminal 37 by the data migration means 38 (arrows H and I) so that accumulation management and analysis of the inspection data can be performed.

[0007]

However, the above-described conventional inspection support system is useful because the processing for determining the abnormal sign of the inspection object is quick and reliable, and the data processing after the inspection work is easy. That human input such as erroneous input has not been reduced because the input work of inspection data etc. is performed manually, and the time required for input work of inspection data etc. has not been shortened. There is room for improvement.

Further, the conventional inspection support system can reliably perform the state determination processing of the inspection object based on the inspection data input to the mobile terminal, but the inspection data itself input to the mobile terminal is visually recognized by the worker. Therefore, a reading error of each instrument of the inspection object occurred, and accurate inspection data could not be collected.

That is, most of the conventional inspection support systems are provided with means for inputting various data to the portable terminal (for example, a keyboard, a mouse, etc.) which are manually operated by an operator. Since the inspection data itself is data visually recognized by an operator, an erroneous input or a reading error in an input operation to the portable terminal occurs at a predetermined ratio, and thus a problem occurs that the accuracy of the inspection data is reduced.

The present invention has been made in view of the above circumstances and reduces the time required for inspection work by inputting inspection data promptly and accurately in patrol inspection, and also provides accurate state data in patrol inspection. The purpose of this is to provide a repair and inspection plan that efficiently performs repairs and inspections as necessary by collecting data and inspection support systems that can determine capital investment plans based on inspection data obtained by patrols and repairs and inspections And

[0011]

In order to achieve the above object, an inspection support system according to the present invention comprises a portable terminal which can be carried at the time of inspection of an inspection object, and analysis and accumulation of various data collected by the portable terminal. A top device that can manage,
In the inspection support system including a data communication network for performing transfer of various data between the upper terminals, the portable terminal includes an input unit and an output unit for various data, and a state determination unit that determines a state of the inspection target. Having various data storage means and data transfer means to the upper terminal,
An identification device capable of recognizing identification data given to each inspection object is provided as the input means.

That is, the inspection support system of the present invention comprises:
When carrying out a patrol inspection and a repair inspection of the inspection target, the user carries the mobile terminal and reads the identification data given to the inspection target by the identification device of the mobile terminal, thereby storing the identification information in the storage means of the mobile terminal. Individual data and type data relating to the inspection object can be displayed on an output screen or the like as an output unit from among all the data that has been inspected.

[0013] Further, as an identification device for the identification data, an optical reading device or a magnetic reading device, such as an optical reading device or a magnetic reading device, capable of mechanically reading optical data or magnetic data without intervention of human thought is applied. Thus, the inspection object can be promptly recognized by the portable terminal. For example, when the identification device is an optical reader, a barcode reader may be applied as the identification device, and a barcode may be applied as the identification data.
Any optical reader may be used, in which numbers, symbols, symbols, and the like are arranged, and the identification device can recognize the identification data.

When the identification device is a bar code reader, if the status data of the inspection object is displayed as a digital bar code corresponding to the bar code reader, the bar code reader can be used as input means for the status data. For example,
When a patrol inspection object is normal, a barcode (identification data) and a digital barcode (status data) are input to a portable terminal with a barcode reader, thereby completing the inspection inspection of the inspection object. The work time can be significantly reduced as compared with the inspection work.

Further, the inspection support system of the present invention can accurately collect the state data of the inspection object in the patrol inspection work, and analyze the accurate state data by the upper terminal to determine the time of the repair inspection. Efficient decisions can be made as needed.
