Description

  The present invention relates to a management method of ultrasonic flaw detection inspection records used for nondestructive inspection of pipes and container welds, and an ultrasonic flaw detection apparatus used therefor.

  In power plants that require a high degree of reliability, it is extremely important to check the soundness of equipment such as pipe welds, but for this check, a nondestructive inspection using ultrasonic flaw detection has traditionally been used. It is used.

  And the ultrasonic flaw inspection for the welded part at this time is also performed when the target power plant is constructed, and the inspection result is acquired as initial data. It is also carried out regularly after the start of commercial operation, and the presence or absence, size, etc. of welds that may occur with the operation of the plant are sequentially confirmed.

  By the way, in the inspection after the start of the plant operation, the inspection must be performed under the same conditions as in the initial data acquisition. Therefore, conventionally, the same contrast test piece is used, flaw detection is performed using the same probe, and the inspection is performed after the ultrasonic flaw detector is calibrated.

  Here, if a defect is detected at the time of construction of the plant or after the start of operation, the test conditions, test results, position, size, shape, etc. of the defect are recorded, and thereafter, the same conditions are used periodically. Inspection is performed and compared with past test results to evaluate the aging of defects, evaluate the progress of defects, and evaluate the remaining life of welds.

  The ultrasonic flaw detector used at this time is usually composed of a pulse transmitter, a probe, a receiver, and a display unit. The probe is brought into contact with the surface of the test body, and ultrasonic waves are passed into the test body. By transmitting, the ultrasonic wave propagated inside the test specimen is reflected by internal scratches and foreign matter and is received by the device as a defect echo. It simply displays the state of the reflected echo as a waveform.

  Therefore, the inspector observes the waveform of the displayed echo to determine the presence or absence of a defect. And to specify the defect position, the surface of the test specimen is marked by scribing, etc., and the defect position and size are specified by pulling the tape measure. At this time, a sensor is attached to the probe, An apparatus that automatically detects the position of the probe and the amount of swing when a defect echo is detected has been proposed as an example of the prior art (see, for example, Patent Document 1).

In addition, when creating the inspection result obtained at this time as a record, it is common for an inspector to read the waveform and describe the defect information to create an inspection record. As an example of the prior art, there has been proposed a method in which acquired waveform data is taken into an ultrasonic flaw detector and analyzed, and defect information is stored in a database (for example, see Patent Document 2).
Japanese Patent Laid-Open No. 5-142213 JP 2003-83944 A

  The above prior art does not take into account the fact that human intervention is involved in the storage of inspection results, and has the following problems.

  First, in nuclear power plant piping, etc., inspection records for over 700 inspection points must be managed manually for a long period of 40 years or more. During this time, inspectors may be replaced. In the prior art, record management is difficult, and the record may be lost.

  Next, in a series of operations related to ultrasonic flaw detection, the amount of information that must be handled by the inspector before and after the inspection and during the inspection is extremely large. For this reason, in the prior art, the inspector cannot obtain the information. It takes a lot of time and effort.

  At this time, by using a device that combines a mass storage device such as a personal computer with an ultrasonic flaw detector, there are cases where past inspection results and necessary information are brought to the site and used. In order to search for necessary information, a person must visually select data from a large amount of information at the site, which may cause human error.

  Further, in the prior art, since the entry and creation of the inspection record is handwritten, the work efficiency is poor, a lot of burden is placed on the personnel, and there is a possibility of erroneous writing due to the manpower.

  In addition, since it is a work by personnel, in the conventional technology, whether or not there is a need for a scaffold for approaching the part to be inspected in the inspection, whether there is anything that hinders the inspection around the inspected body, In the case of a nuclear power plant or a facility related to nuclear power, it is necessary to confirm in advance, but in areas where the radiation is at a high dose, it can be confirmed only when the plant is shut down and the radiation dose is low. Although it is a low dose, there is a possibility of exposure, so there is a safety problem.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an ultrasonic flaw detection inspection apparatus and an ultrasonic flaw inspection inspection record management method that do not cause any omission in record storage of inspection results.

  In the ultrasonic flaw detection inspection record management method in which the inspection object is inspected for defects by ultrasonic flaw detection and the inspection result is recorded and stored, the inspection object is held with a RFID tag, and the RFID The test result is stored in a tag memory, and a record keeping of the test result is provided by the test object.

  At this time, at least one of the past inspection record and the attribute information necessary for the inspection of the inspection object may be recorded and stored in the memory of the RFID tag, and stored in the memory of the RFID tag. Information may be transferred to a database, and inspection records may be managed on the database.

  Further, at this time, the inspection record in the database may be output to the inspection record sheet format so that the inspection record is managed on the inspection record sheet format. Means for displaying the environment on the three-dimensional CAD may be provided.

  Similarly, in the ultrasonic flaw detection inspection apparatus that inspects the presence or absence of a defect of an inspection object by ultrasonic flaw detection with a probe, an RFID information writing unit for writing at least the inspection result by the ultrasonic flaw detection to an RFID tag is provided. It is provided that at least the inspection result is stored in a memory of an RFID tag held on the inspection object.

  At this time, in the case of the embodiment of the present invention, when managing inspection records of a large number of inspection target parts over a long period of time, in order to easily manage data without being affected by the replacement of inspectors or the passage of years, The main feature is that an RFID tag is used for one inspection object, and past inspection records and other attribute information and a new inspection record are recorded in the RFID tag and managed in an integrated manner.

  At this time, the data in the RFID tag is transferred to the large-capacity storage database using a reader / writer, and the data is managed by both, whereby management with higher reliability becomes possible.

  Also, in the case of the embodiment of the present invention, in order to perform inspection work efficiently on the site, attribute information such as past inspection records and device calibration conditions is written on the RFID tag and pasted in the vicinity of the welded portion to be inspected. Thus, it is possible to confirm information with a reader / writer before and after the inspection and during the inspection.

  Here, in the ultrasonic flaw detection according to the embodiment of the present invention, the amount of information referred to by the inspector is very large, and in order to extract necessary information from the information without mistake, welding in the RFID tag is performed. The inspector can obtain only the necessary information by recording the minimum information necessary for the inspection of only the section and reading it with a reader / writer.

  At this time, the inspection record is written from the ultrasonic flaw detector to the RFID tag, and the information is transferred to the database by the reader / writer. Can be reduced. At this time, the computer automatically outputs the inspection record in the database to the inspection record sheet format, thereby making it possible to create the inspection record accurately and efficiently without human intervention.

  In addition, in the case of the embodiment of the present invention, design information and inspection records are stored as attribute information in the inspection target portion on the 3D-CAD using 3D-CAD that displays the positional relationship between the inspection object and the surrounding environment. This allows the inspector to easily obtain the necessary information before the test on the 3D-CAD screen in the computer, and to check the surrounding environment of the inspection target area on site every time. You can reduce your going.

  According to the present invention, the inspection record and other attribute information are stored in the RFID tag held in the object to be inspected, so that there is no possibility of losing information on the object to be inspected, and therefore record management is easy. In addition, it is possible to manage the recording with certainty.

  In addition, according to the present invention, inspection records and other attribute information can be centrally managed in the RFID tag or on the database, thereby improving the reliability of the data and easily obtaining the data even in the field or in the office. be able to.

  Since past inspection records and other information can be confirmed in the field in this way, according to the present invention, necessary information can be obtained easily and quickly, and the same apparatus and probe as those used for the first inspection are used. However, when the test apparatus must be calibrated under the same conditions, it is possible to reduce the human error in the selection of the apparatus and its correction method.

  Further, according to the present invention, by using a reader / writer, the position of the defect can be grasped in advance from the past inspection record, and preliminary knowledge can be obtained, so that the inspection work efficiency and reliability can be improved. Can do.

  Furthermore, according to the present invention, since record entry, which has been performed manually in the past, is performed by a computer, the efficiency of creating an inspection record can be improved, and human errors such as errors can be reduced.

  At this time, according to the present invention, it is possible to perform an embodiment in which the surrounding environment of the welded part to be inspected, the inspection record, etc. can be confirmed on 3D-CAD. In addition to being able to confirm the situation on the computer at any time, work efficiency is improved, and in the case of a nuclear power plant, exposure can be reduced.

  Hereinafter, an ultrasonic inspection inspection record management method and an ultrasonic inspection inspection device according to the present invention will be described in detail with reference to the illustrated embodiments.

  FIG. 1 is an example of the arrangement of equipment necessary for ultrasonic flaw detection inspection in one embodiment of the ultrasonic flaw detection inspection record management method according to the present invention. Here, as an example, the piping of a power plant is the inspection object 1. The case where the inspection target part 2 such as the welded part is nondestructively inspected by the ultrasonic flaw detector 3 is shown.

  For this reason, the ultrasonic flaw detector 3 uses the probe 4 to transmit an ultrasonic pulse into the inspection target part 2 and receive a reflected echo due to a defect or the like to inspect the inspection target part 2. However, in this embodiment, the ultrasonic flaw detector 3 is provided with an RFID information writing unit, and at the same time, the surface of the inspection object 1 is positioned in the vicinity of the inspection object 2 in advance. The RFID tag 5 is attached.

  Here, the RFID information writing unit is a part that functions to write information to the RFID tag, and the RFID tag at this time is a tag (Radio Frequency Identification Tag) capable of identification confirmation by radio frequency This is affixed in the vicinity of the inspection object part 2 as the RFID tag 5.

  At the time of inspection, the ultrasonic flaw detector 3 processes the reflected echo received by the probe 4 according to the method described later, and detects the presence / absence of a defect in the inspection target portion 2, the position and size of the defect, and the detection of the defect. Data such as the position of the touch element 4 is created and transferred to the RFID tag information writing unit described above.

  At this time, in the storage unit of the RFID tag 5, as will be described later, the individual management number of the inspection target unit 2, the type and model number of the ultrasonic flaw detector 3 and the probe 4 used at this time, the device Register the attribute information necessary for inspection, such as the number of the contrast specimen used for calibration, calibration record / calibration conditions, and past inspection records.

  On the other hand, the reader / writer 6 is used to read the attribute information registered in the storage unit of the RFID tag 5, and when reading, the reader / writer 6 is arranged within a range where the information of the RFID tag 4 can be read. Although used, the reader / writer 6 is provided with a display unit so that the inspector can confirm the information.

  The reader / writer 6 is also used to write the attribute information described above to the storage unit of the RFID tag 5, and therefore, in addition to the display unit described above, a data input man-machine interface such as a keyboard is provided. .

  The reader / writer 6 has a data transfer function. By using this reader / writer 6, inspection records written in the RFID tag 5 and other attribute information can be transferred to the database 7. Data can be taken from the database 7.

  Data transfer at this time may be transmission by direct wiring connection, or may employ a method of transmission without using a wireless compatible device. For this reason, a memory device capable of storing a large amount of data is used for the database 7.

  Information such as inspection records stored in the database 7 can be read by the computer 8 via a connection medium such as a local area network (LAN) so that the data can be confirmed on the display 9. It has become.

  At this time, the computer 8 functions to read and display the information in the database 7 described above. In addition, as will be described later, the computer 8 evaluates the crack progress of defects detected by inspection, and automatically records inspection records. It also has functions such as output.

  Next, the operation of this embodiment will be described with reference to FIG. Here, FIG. 2 shows a work procedure for managing the ultrasonic flaw detection inspection record using the ultrasonic flaw detection apparatus 3, the RFID tag 5, the reader / writer 6, the database 7, the computer 8, and the display 9. It is a thing.

  First, in step 10, the inspector confirms the inspection plan and the like, confirms the management number of the inspection target part where the inspection is planned, and then in step 11, checks whether the inspection target part has an inspection record. To do. Here, in the case of the first inspection, there is no result in step 11 (no inspection results). Therefore, at this time, the process proceeds to step 12, where the reader / writer 6 is used to write the initial data shown in FIG.

  If the RFID tag 5 is not pasted in the vicinity of the inspection target portion even though there is an inspection result in the procedure 11, the reader / writer 6 is used as the procedure 12, and the initial data and past inspection records shown in FIG. Write to tag 5. Thereafter, in step 13, the RFID tag 5 is attached in the vicinity of the inspection target portion 2. At this time, a position where the ultrasonic flaw detector 3 and the reader / writer 6 can read and write information is selected as the pasting position.

  After this step 13, the process proceeds to step 14, where the inspector uses the reader / writer 6 to record the information recorded in the RFID tag 5, that is, the ultrasonic flaw detector 3 and the probe to be used at this time. The information of the model number of the child 4 is read, and the inspector confirms that it matches the one that is about to be used.

  On the other hand, when the result of step 11 is present (there is an inspection result), that is, when there is an inspection result and the RFID tag is attached in the vicinity of the welded portion to be inspected, the process proceeds to step 14 after step 11, Similarly, the ultrasonic flaw detector 3 and the probe 4 are confirmed.

  Next, in step 15, the inspector uses the reader / writer 6 to check the comparison specimen number stored in the RFID tag 5 and the calibration conditions of the apparatus at the time of the first inspection. The inspector calibrates the ultrasonic flaw detector 3 so that The calibration result at this time is written in the RFID tag 5 as one item of the inspection result by the inspector using the reader / writer 6.

  After calibrating the apparatus in this way, in step 17, the inspector uses the reader / writer to check the past inspection results stored in the RFID tag 5, the presence or absence, position, size, etc. of the defect. The worker uses the ultrasonic flaw detector 3 to start flaw detection work. Then, the inspection result obtained by this flaw detection work is written in the RFID tag 5 as inspection records such as defect position information from the ultrasonic flaw detector 3 by the method shown in FIG.

  Thereafter, in step 19, first, the inspector uses the reader / writer 6 to transfer the inspection record written in the RFID tag to the database 7, and the transferred inspection record is stored in the database 7 as an individual inspection target part. It is managed after being assigned to a management number.

  In the following procedure 20, when the stress state received by the inspection target portion is evaluated and the stress value is recorded in the database 7, as the next procedure 21, the defect progress rate and the usage period of the inspection object are used. The amount of progress is calculated by the computer 8. In the calculation at this time, the position, shape, and size of the defect recorded in the database 7 are taken into consideration, as well as the shape and thickness of the inspection object 1 and the stress state that the defect detection unit receives at this time. Used.

  In addition, about the standard of the defect evaluation in the welded part at this time, there are a standard specified in WES 2805-1997 by the Japan Welding Association and a maintenance standard JSMES NA1-2004 by the Japan Opportunity Association, and therefore conform to these standards. do it.

  At this time, when 3D-CAD is included in the software of the computer 8, in step 22, the inspection record history together with the position information of the defect detection unit, and the predicted progress of the defect during the use period calculated in step 21, It is displayed on the 3D-CAD software as one of the attribute information of the inspection object part.

  In step 23, the computer 8 reads the inspection result, the calibration result, and the like in the database 7, automatically outputs the result to the inspection recording paper format, and creates the inspection recording paper. Here, FIG. 3 shows an example of initial data and inspection records written in the RFID tag 5 at this time.

  In FIG. 3, first, the initial data is data that is recorded in advance in the RFID tag 5 as information necessary for the inspection before the first inspection. Prior to the inspection of the place where the tag 5 is not used, the past inspection record is recorded in the RFID tag 5 together with the initial data, which is the past inspection record. During the inspection, new inspection records are sequentially recorded on the RFID tag 5.

  Therefore, according to this embodiment, since the inspection record and other attribute information are stored in the RFID tag held in the inspected object, the information regarding the inspected object is always together with the inspected object. ing. As a result, there is no possibility of losing information, so that record management becomes easy and requires no manpower, and records can be managed reliably.

  In addition, according to this embodiment, inspection records and other attribute information are centralized and managed by the RFID tag 5 and the database 7, so that the ultrasonic flaw detection result can have high reliability and the inspection can be performed. Data on the object 1 can be easily obtained in the field or in the office. As a result, past inspection records and other information can be confirmed on the site, so the same equipment and probe as the first inspection are used and the same conditions are used. Even when the test apparatus has to be calibrated, human error can be reduced.

  Further, according to the above embodiment, by using the reader / writer 6, the position of the defect can be grasped in advance from the past inspection record and the preliminary knowledge can be obtained. Since the entry is performed by a computer and no manual work is required, it is possible to improve the efficiency of creating the inspection record and reduce human errors such as typographical errors.

  Next, an embodiment of an ultrasonic flaw detector 3 capable of writing data to an RFID tag will be described with reference to FIG. Here, first, reference numeral 24 denotes a main body of the ultrasonic flaw detector, which includes a probe 4, a pulse transmitter 25, a receiver 27, and a display unit 28.

  Therefore, the ultrasonic flaw detector main body 24 is also general, but in this embodiment, the inspection result information can be written in the RFID tag 5, and therefore, in addition to the ultrasonic flaw detector main body 24, A A / D converter 29, a CPU 30, a probe position measuring device 31, and a writing device 32 corresponding to the RFID information writing unit described above are provided.

  Next, the operation of the ultrasonic flaw detector 3 will be described with reference to FIG. 3. The probe 4 receives the pulse supplied from the pulse transmitter 25 and generates an ultrasonic wave, whereby the ultrasonic wave is inspected. Incident into the object 1. The incident ultrasonic waves are reflected by the bottom surface and defects of the inspection target part 2, return to the probe 4 as reflected waves, and are supplied to the receiver 27 as reflected echoes.

  Therefore, this reflected echo is supplied as an electric signal to the display unit 28 and displayed as a waveform, and this electric signal is also supplied to the A / D converter 29, where it is converted into digital data, as shown in FIG. The waveform data is supplied to the CPU 30.

  At the same time, the probe position measuring device 31 detects the position of the probe 4 and sequentially supplies the position information to the CPU 30. At this time, the probe position measuring device 31 functions to detect the position of the probe 4 on the surface of the object 1 to be inspected. For example, the probe position measuring device 31 disclosed in JP-A-5-142213 is used. That's fine.

  Therefore, the CPU 30 inputs the transmitted waveform data and position information and determines the data to be supplied to the writing device 32 by processing according to the method described later with reference to FIG. The writing device 32 can manage the ultrasonic inspection result as described above by receiving the data transmitted by the CPU 30 and writing it in the RFID tag 5.

  At this time, it is necessary to arrange the ultrasonic flaw detector 3 at a position where the inspection result by the writing device 32 can be written into the RFID tag 5 as already described in the embodiment of FIG.

  Next, in the ultrasonic flaw detector 3 shown in FIG. 4, the processing from when the probe 5 receives the reflected echo after the start of the flaw detection operation until data is written to the RFID tag 5 will be described with reference to FIG. .

  The processing of FIG. 5 is executed by a program installed in the CPU 30. Therefore, if the flaw detection operation is started and an ultrasonic wave is emitted, the probe 4 receives the reflected wave and the reflected echo is supplied to the receiver 27 (step 33). Next, an electric signal by the reflected echo is sent from the receiver 27 to the A / D converter 29 (step 34), and the received electric signal is converted into digital data by the A / D converter 29 (step 35). Digital waveform information is supplied to the CPU 30.

  In parallel with this, the position information of the probe 4 is detected by the probe position measuring device 31. This position information is also supplied to the CPU 30 (step 36). Therefore, waveform data and probe position information to be transferred to the writing device 32 are determined from these pieces of information (step 37), and these are then integrated as one data group (step 38). In addition, about the process at this time, the arithmetic processing shown in FIG. 8 mentioned later can also be used.

  Thereafter, the write data is transferred from the CPU 30 to the writing device 31 (step 39). As a result, the data writing to the RFID tag 5 is obtained.

  Next, the ultrasonic flaw detection waveform obtained by the ultrasonic flaw detection apparatus 3 will be described with reference to FIG. 6. First, this figure shows a waveform when the ultrasonic flaw detection result is displayed on an A scope. Sometimes the vertical axis is the echo height (the intensity of the reflected echo), and the horizontal axis is the ultrasonic propagation distance.

  In FIG. 6, the height (intensity) of the detected reflected echo is represented by level E, and the threshold value (threshold) for determining that the reflected echo is a defect echo is represented by level Eth. However, the threshold value Eth is preset in the CPU 30 as data. At this time, the ultrasonic propagation distance when the defect echo is detected is indicated by W.

  6 is displayed as analog data on the display unit 28 of the ultrasonic flaw detector 24 and converted to a digital value by the A / D converter 29 and supplied to the CPU 30 as described above. Here, the defect echo is determined, and the result is written to the RFID tag.

  Next, FIG. 7 shows an example of data that is written to the RFID tag 5 at this time and used for calculation when determining the inspection result later, and data that is written after the calculation. As shown in the figure, these include information relating to waveform data, information relating to the position of the probe 4, and information relating to defects.

  First, the waveform data information includes an echo height E, a maximum echo height Emax, a defect recognition threshold Eth, an ultrasonic propagation distance W, and an ultrasonic propagation distance Wmax when detecting the maximum echo height. There is.

Next, the position information of the probe 4 includes the X-direction position X of the probe, the Y-direction position Y of the probe, the probe swing angle θ, the ultrasonic incident angle φ, and the X at the time of defect detection. There is a probe position X _{p in} the direction, a probe position Y _p in the Y direction when a defect is detected, and a swing angle θ _p of the probe when a defect is detected.

The defect information includes defect number Def I, defect X-direction position X _d , defect Y-direction position Y _d , defect Z-direction position Z _d , defect X-direction length l _x , defect There is a length l _y in the Y direction.

  Next, a process for determining data to be transferred to the writing device 31 in step 37 of FIG. 5 will be described with reference to FIG. Here, this processing is executed by a program stored in the CPU 30, and symbols used in FIG. 8 are as shown in FIG.

  When the process of FIG. 8 is started, first, it is determined whether or not the defect echo height E exceeds the threshold value Eth (step 43). First, if not exceeded, data initialization processing is executed (step 52), and the program ends here. In this data initialization process, the maximum echo height Emax, the maximum values Xmax and Ymax of the probe position, and the minimum values Xmin and Ymin are set to 0, respectively.

  On the other hand, if the maximum echo height Emax exceeds the threshold value Eth in step 43, it is determined whether or not the maximum echo height Emax is 0 (step 44). If the maximum echo height Emax is not 0 and the echo height E does not exceed the maximum echo height Emax (step 45), the program ends here.

If the maximum echo height Emax is 0 in step 44, or if the echo height E is greater than the maximum echo height Emax in step 45, first, the maximum echo height Emax is set to the echo height E and the maximum echo height. upon detection of the ultrasonic wave propagation distance Wmax in W is respectively replaced (step 46), then the position of the maximum echo height at the time of detecting probe _{4 (X p, Y p,} θ p) position (X, Y, θ) (step 47).

Then, from the probe position (X _p , Y _p , θ _p ) when detecting the maximum echo height, the ultrasonic propagation distance Wmax when detecting the maximum echo height, and the ultrasonic incident angle φ, the following calculation formula Is used to calculate the position (X _d , Y _d , Z _d ) of the defect (step 48).

X _d = X _p + Wsinφ / √ (1 + tan ² θ)
Y _d = Y _p + W sin φ · tan θ / √ (1 + tan ² θ)
Z _d = −cosφ

In step 43, if the echo height E exceeds the threshold value Eth, the position (X, Y) of the probe is successively monitored, and the maximum value Xmax, Ymax and minimum value Xmin, Yuki update the ymin, it calculates the X direction length l _x and Y direction length l _y defect (step 50).

Then, after the processing of step 48 and step 51 is completed, each defect data Def i = (Emax, Wmax, X _p , Y _p , θ _p , X _d , Y _d , Z _d , φ, l _x , l _y ) are given (step 49), and the program ends here.

  Therefore, according to the ultrasonic flaw detection apparatus 3, the function as the ultrasonic flaw detection inspection record management method can be sufficiently exhibited when applied to the embodiment of FIG.

  The present invention can be applied, for example, to soundness evaluation of a welded part using an ultrasonic flaw detector such as a pipe of various power plants or a welded part of a container.
