In particular, the identification and unique information of industrial infrastructure facilities using radio frequency identification (hereinafter referred to as 'RFID') technology After attaching the recorded RF Tag to the inspection location of the facility, and recognizing the identification and unique information of the facility to which the RF tag is attached through the RF tag read / write device, the portable computer Through the access to the management server through the system to check the relevant information of each facility or record the inspection results of the facility, the industry using the RFID technology to perform the overall history and maintenance of the industrial facilities more systematically and efficiently It relates to the information management system of infrastructure.

In general, the maintenance plan for the current Class 1 facility under the “Special Act on the Safety of Facility Facilities” includes overhaul at least once every three years, and once every five years as a facility that has passed ten years since its completion. There is a precision safety diagnosis.

The overhaul is an inspection to accurately determine the current state of the facility by scheduled periodic inspections, to confirm changes from the original or previously recorded state, and to ensure that the structure continues to meet the current use requirements.

In addition, the precision safety diagnosis is a close inspection that includes a precise visual inspection and measurement by measuring equipment that is performed to find a defect site that is not easily found through a precision inspection process.

In the history and maintenance of industrial infrastructure facilities through the above-mentioned precision inspection and precision safety diagnosis, conventionally, some servers, such as drawings and specifications of the structure, design books, maintenance reinforcement history and calculation load capacity, inspection history, etc. Although the database is stored as computer files and stored and managed, the systematic and objective history management and maintenance such as loss of related data occurs due to frequent changes of managers. In case of, it is hard to expect to keep related data such as design books and plumbing diagrams, so it is very difficult when constructing newly constructed facilities in the neighboring area.

In other words, the inspection method that is conventionally performed, the inspector is put into the field with the relevant drawings, field yards, etc. of the facility to perform the on-site work and the daily inspection and precision inspection, where the damage occurs, the degree of damage, etc. The results of the verification are manually entered into the field, and several photographs are taken and recorded in future reports, and the manager manages these reports in the library.

Therefore, not only is there a lot of difficulties in the field work, but the amount of information that can be inquired and referenced in the field is not only limited, but a series of hysteresis, such as the progress of cracking, is difficult only by regular visual inspection alone, and thus effective measures are limited. . In particular, although the damage may seriously affect the structure, depending on the skill of the inspector, it may be missed during on-site inspection, and the same damage may be different from the field manager or report due to the subjective judgment of the expert (expert) or the unskilled person (non-expert). There is a problem that results may be recorded or different measures may be established accordingly.

In addition, facilities such as plants, nuclear power plants, etc. are scattered with related equipment and equipment, and dangerous situations may be caused by carelessness of inspectors.

When detecting a signal within the effective range consists of an antenna for transmitting the identification and unique information recorded in the IC chip or memory.

The IC chip or memory of the RF tag 11 includes the identification and unique information of the facility 10, that is, the serial number, the facility name, the date of construction, the deadline for the inspection, the deadline for the accurate safety diagnosis, and the like. Various various information is recorded, and more additional information may be recorded through the RF tag lead / writer 21.

In addition, by providing a sensor input terminal to the RF tag 11, in the case of the inspection of the facility that is not possible to continuously visually inspect, despite the need for continuous observation and quantitative data such as crack propagation, inclination, etc. The RF tag 11 is attached to the facility 10 and the inspection and measurement data are stored in the IC chip or memory of the RF tag 11 at regular intervals. By backing up and verifying these facilities, accurate inspections can be made.

In this case, the RF tag 11 is configured to perform a CPU and a main operation function like an embedded system, and the maximum, minimum, and maximum values may be set by a program that presets measurement values of sensors connected to a sensor input. Representative values such as average value and frequency analysis value can be calculated by itself to transmit only representative values necessary for analysis.

The RF tag 11 includes both an active RF tag with its own power source and a passive RF tag that can be driven by an externally applied power source. In the case of the RF tag, the power circuit unit utilizes not only its own AC power but also a battery which can be charged, exchanged or removed, or is supplied with operating power by a solar cell.

In addition, the RF tag 11 checks the operation state of the RF tag 11 to set a sleep mode when the sensing or communication function is not performed for a predetermined time so that the power circuit unit supplies only standby power. The apparatus further includes a sleep mode control unit for releasing the sleep mode by wireless remote control or sensing operation to control supply of operating power to each unit normally.

The RF tag 11 as described above is attached to a predetermined inspection position of the industrial facility 10 through a bracket structure, especially if the facility 10 to be checked is a concrete structure to the concrete structure Attach the mounting base (Mounting Base) directly with an adhesive or the like, and fix the bracket of the RF tag 11 to the mounting base by a fixing means such as a stud or a bolt (Stud) or the RF tag 11 to concrete To be attached to the structure.

In addition, when the industrial facility 10 to be checked is a steel material structure, a magnet is attached to the bracket of the RF tag 11, and the RF tag 11 is attached to the steel material structure by the magnet. Let's do it.

In the case of the portable computer 22, it is possible to use PDA (Personal Digital Assistants) as a kind of portable computer, or may use a PDA equipped with a camera.

That is, to maintain the security of the management server 30, to ensure that the inspector checks all the facilities 10 of the inspection object without missing, to ensure the quality of inspection management.

 Thereafter, the site inspector performs a check on the facility 10 according to the main check list identified in step S4 to prepare a check result for each main check list (S5), that is, on the facility 10 Record various damage history information, date of inspection, inspection history of inspector, name of inspection company, maintenance reinforcement history, current status, etc.

At this time, the state of the facility 10 at the inspection position of the facility 10 can be recorded using the digital camera 23 or the camera installed in the PDA, and the corresponding photo information can be recorded in the management server 30.

In other words, in order to acquire accurate image information about damage such as crack width and length, a known length or area body is attached to the measurement target surface, and then image processing techniques are taken to record and record the image to quantitative damage information ( Crack width, crack length, white area, peeled area, etc.) can be obtained automatically.

In the inspection of the facility 10 divided into the daily inspection and the precision inspection as described above, in the case of daily inspection, various inspection results on the inspection position of the facility 10 with the RF tag 11 is attached even by an unskilled person Record, and can access the vast data contained in the management server 30 through the wireless LAN to check the previous status, relevant data, etc. of the facility 10 and update the new information form by the conventional non-skilled person It is possible to prevent the deterioration of quality with a general inspection level.

On the other hand, the manager is connected to the management server 30 through the manager PC 40, from the management server 30 to check the check results for the main check list of the facility 10 (S6), such a ratio Even when inspected by skilled personnel, it is possible to carry out systematic records, maintenance and countermeasures against quantitative quality assurance and damage development.

That is, when clicking on the inspection position where the RF tag 11 is attached to the facility 10 displayed on the manager PC 40, the results recorded by the inspector, that is, the maintenance reinforcement history, as well as the past damage, As it is possible to check the current status, it is possible not only to manage the history and trend analysis, but also to present the quantitative judgment criteria as a quantitative basic data for determining the investment priority for reinforcing reinforcement of the entire facility under the management. You can do it.

On the other hand, in the present invention, when the communication by the wireless LAN is limited in real time, such as a tunnel, the related DB of the facility 10 is downloaded from the management server 30 and backed up to a laptop and storage device, Bring it to the site can perform the same operation as described above in the field, and to update after connecting to the management server 30 for the new information obtained after the operation.

In addition, in the case of inspection of a facility where continuous visual inspection is impossible despite continuous observation and acquisition of quantitative data such as crack propagation and tilting, an RF tag 11 having a sensor input terminal is used. The RF tag 11 is attached to the facility 10 and the inspection and measurement data are stored in the IC chip or memory of the RF tag 11 at regular intervals. By backing up and verifying these facilities, accurate inspections can be made.

As described above, the present invention, by using the RFID technology to attach the RF tag recorded the identification and unique information for the inspection of the industrial period facilities to the inspection location of the facility, and through the RF tag read / write machine After recognizing the identification and the unique information of the facility attached to the RF tag, it is connected to the management server through a portable computer to check various related information of the facility or record the inspection result of the facility according to the main check list. The overall history management and maintenance of infrastructure can be effected more systematically and efficiently.

As described above, in the present invention, in accordance with the attachment of the RF tag using RFID technology, the quantitative inspection for damages that need to be inspected by the non-skilled persons in the daily inspection (information recording on damage, such as photographing, crack width and length, and other damages). Information such as judgment information, inspection date, inspector's name, inspection company record, etc.), so that there is no missing inspection even through inspection by unskilled personnel and objective results are output. In case of damage, a new RF tag may be attached by a skilled worker at the time of detailed inspection to enable investment prioritization for quantitative maintenance and maintenance of the entire facility.

In the present invention, it is very convenient in the field work as it is easy to carry only portable devices such as RF tag lead / lighter, portable computer, digital camera, etc., and the inspector can view the vast data recorded on the RF tag or management server in the field. As a result, time reduction and quantitative data acquisition are possible.
