Description

  The present invention relates to a coating film diagnosis system for diagnosing the state of a coating film and an undercoat substrate coated on a steel structure, outputting the results, and proposing specifications for repainting as necessary.

  The outer wall of various structures plays an important role not only from an aesthetic point of view but also from the viewpoint of protecting the outer wall material in the case of a metal structure such as an oil tank. The coating film applied to the outer wall deteriorates over time. As a result, not only the aesthetics of the structure are impaired, but also the base metal of the structure is corroded by the penetration of the corrosion factor through the coating film, and the coating peels off as the corrosion further proceeds. If this condition is left unattended, not only will it cause aesthetic problems, but it will also shorten the life of the structure, so it is necessary to repair and repaint before the deterioration of the coating film and the substrate under the coating progresses. There is.

  On the other hand, it is difficult to judge whether or not the coating film needs to be repaired or repainted, and it has often been necessary to consult an experienced painter. Even for an experienced painter, the criteria for judgment vary depending on the painter, and objective judgment is not always made.

  Therefore, there is a technique for evaluating the deterioration state of the coating film by image processing the image data obtained by imaging the coating surface of the structure, and outputting a diagnosis result obtained from the deterioration state (for example, Patent Documents). 1). According to such a technique, since the deterioration state is evaluated according to a predetermined evaluation criterion, it is possible to eliminate variations in the diagnosis result.

  Moreover, the diagnosis of the deterioration state of the coating film by the technique as described above is based on the ratio of the peeling area of the coating film surface and the total area of the rust portion in a predetermined reference area of the structure. That is, one piece of image data is obtained from the structure, and the deterioration state of the coating film is diagnosed based on the ratio of the peeled portion or the like in the image data.

  Here, the coating film of the structure disposed outdoors is not actually deteriorated under uniform conditions as a whole. For example, the structure includes a portion that is easily exposed to rainwater, a portion that easily collects water, a portion that is easily exposed to direct sunlight and deteriorates, and the environmental conditions are different for each portion. In addition, non-uniform degradation may occur in the structure due to non-uniformity of the original substrate. For these reasons, the entire surface of the structure is hardly deteriorated uniformly.

  The above-described technique has a problem that accurate diagnosis of each part cannot be performed because the entire structure is imaged and diagnosed with one image data. For example, there is a case where a diagnosis that the coating film is good overall is made despite partial repair.

  In addition, even if it looks sound to the outside, sometimes it appears to be healthy, such as a thick-film epoxy resin paint or a vinyl ester resin-based paint containing glass flakes. There is a case where the deterioration has started. In such a case, the deterioration cannot be found, and the deterioration proceeds under the coating film. As a result, the strength of the structure is lowered, which may be a dangerous situation.

  Furthermore, if an inappropriate coating film diagnosis is performed, and repair and repainting are performed, re-deterioration is caused, resulting in unnecessary costs.

  Hereinafter, the best mode for carrying out the present invention will be described. The description of the present embodiment is an exemplification, and the present invention is not limited to the following description.

<Embodiment 1>
Prior to the description of the coating film diagnosis system according to the present embodiment, a storage tank that is an example of a steel structure that is a target for coating film diagnosis, and an investigation unit that quantifies the state of the coating film in the storage tank will be described. .

  FIG. 1 is a diagram illustrating a storage tank which is an example of a steel structure according to the first embodiment. The steel structure refers to a structure in which a portion to be coated to which a coating film is applied is made of steel. Moreover, the steel here includes low alloy steels such as weather resistant steel. As shown in FIG. 1, the storage tank 1 is formed in a columnar shape, and a coating film is formed on its outer wall surface by painting. A diagnosis area is determined on the outer wall surface of the storage tank 1. The diagnosis region is a region obtained by dividing the region of the storage tank 1 where the coating film is provided. Each diagnosis area is assigned an address for uniquely identifying these areas. In the present embodiment, the storage tank 1 is divided into a total of nine diagnostic areas and assigned addresses 1-9. For example, if the address is “1”, the diagnostic area at the upper left in the figure is specified.

  The investigation means quantifies the state of the coating film and the substrate under the coating film. Here, quantifying the state of the coating means various properties of the coating, for example, peeling, blistering, degree of rust, coating thickness, coating composition, adhesion and other physical properties, This refers to obtaining measured values of electrical properties such as resistance and capacity. Quantifying the state of the substrate under the coating means obtaining measured values of electrochemical properties such as polarization resistance or polarization capacity at the coating-substrate interface. Say. In the present embodiment, the following is used as the investigation means.

(1) Visual inspection: A painter visually examines a rusted portion, a bulged portion or a peeled portion of the coating film, and estimates the ratio of the total area of these portions to the area of the diagnostic region. This ratio is called the deterioration area rate.
(2) Image processing analysis: For example, the storage tank 1 is imaged by an imaging means such as a digital camera, and the image data of the storage tank obtained thereby is processed by the information processing device to calculate the deterioration area ratio.
(3) Under-coating corrosion measurement: Using a corrosion diagnostic apparatus, data on the coating area resistance, coating film capacity, polarization resistance of the under-coating substrate, and polarization capacity of the under-coating substrate is obtained. As the corrosion diagnosis apparatus, for example, an undercoat corrosion measurement apparatus as described in Japanese Patent No. 3051153 is used. From these data, the deterioration condition of the coating film and the corrosion condition of the substrate under the coating film can be understood.
(4) Chemical analysis of the coating film: A coating history is obtained by observing the cross section of the coating film in the diagnostic region. The painting history is the type and number of times of the coating film. Moreover, the resin system of a coating film is specified by FT-IR (infrared absorption spectrum method).
(5) Film thickness measurement of coating film: The film thickness of the coating film is measured using an electromagnetic film thickness measuring instrument.
(6) Adhesion investigation of coating film: Adhesion is investigated by adhesion tester (method according to JIS K 5600-5-7) or cross-cut test (method according to JIS K 5600-5-6).

  The investigation means (1) to (6) are performed for each diagnosis area. Moreover, these investigation means are illustrations and are not limited to those described above as long as the degree of the state of the coating film and the substrate under the coating film can be quantified.

  The coating film diagnosis system according to the present embodiment determines and outputs the deterioration state of the coating film and the base material under the coating film based on the investigation result obtained by implementing such investigation means. Hereinafter, the coating film diagnosis system will be described in detail.

  FIG. 2 is a schematic configuration diagram of the coating film diagnosis system according to the first embodiment. As shown in the figure, the coating film diagnosis system includes a CPU, a storage device (RAM / hard disk, etc.), an input device (keyboard / mouse, etc.), an output device (display, etc.), a communication means, etc. An information registration unit 20, an image processing unit 21, a survey result registration unit 22, a determination criterion registration unit 23, a determination unit 24, and a report output unit 25 are provided. The coating film diagnosis system also includes a database 40 on which various data are recorded or read.

  Each of these means 20 to 25 is implemented as a program executed by the information processing apparatus 10. However, these means 20 to 25 are not limited to being executed as a single program. For example, each means 20-25 may be an individual program executed by each of a plurality of information processing apparatuses, or may be configured by hardware such as an electronic circuit.

  The matter information registration unit 20 registers matter information including an address that uniquely identifies a plurality of diagnosis areas in the database. In addition to registering the address, the project information may include information on the structure to be diagnosed for the coating film and the substrate under the coating film. Such information includes, for example, the name of the structure, the information of the client who requested the diagnosis, the request date and time, and the like.

  The image processing means 21 is a function implemented in the information processing apparatus 10 as one of investigation means. The image processing means 21 first takes in the image data of the storage tank 1 imaged by an imaging means such as a digital camera. This image data is taken for each diagnostic region of the storage tank 1. Then, the image processing means 21 registers the image data captured for each diagnosis area in the database 40 in association with the address. Thereby, each image data is specified by the address. Thereafter, the image processing means 21 finally performs image processing such as binarization on the image data of each address, and determines that the portion exceeding the predetermined threshold is rust, crack, or peeling, and such a portion is The ratio of the image data to the diagnosis area is calculated. This ratio is referred to as a deteriorated area rate, and the deteriorated area rate by image processing analysis is registered in the database 40 via the survey result registration means 22 described later as one of the survey results.

  The survey result registration unit 22 registers the survey result obtained by performing the survey unit described above for each diagnosis area in the database 40 in association with the address. Specifically, the survey result registration means 22 registers the address of the diagnostic area input via an input device such as a keyboard and a mouse and the survey result corresponding to the address in the database 40. Of course, the survey result is not limited to a keyboard or the like, but may be input directly from the survey means via a communication cable such as RS232C or USB, or input via a recording medium such as a non-volatile memory or a CD-R. It may be done.

  The criterion registration means 23 registers a criterion for determining a deterioration state indicating whether or not the coating film has deteriorated from the investigation result in the database for each investigation means. Degraded state is information indicating whether or not the coating film has deteriorated enough to require repair or re-repair due to rust or peeling. Judgment criteria refer to the survey results and the survey results in advance. This refers to the correspondence with the defined state of deterioration of the coating film.

  The deterioration state may be, for example, a binary value with “1” indicating a deteriorated state and “0” indicating a non-deteriorated state. In addition, the degree of deterioration may be expressed by, for example, a 5-stage numerical value. In addition, as a determination criterion, for example, there is one that determines a deterioration state depending on whether or not an investigation result exceeds a certain threshold value.

  The determination unit 24 determines, for each survey unit, the deterioration state of the diagnostic region specified by the address, based on whether the survey result registered in the database 40 by the survey result registration unit 22 meets the determination criterion. Whether or not the survey result conforms to the determination criterion is determined by reading the survey result registered in the database 40, extracting the determination criterion corresponding to the numerical value of the survey result from the database 40, and determining the deterioration state. . For example, when the criterion is “deteriorated when the visually deteriorated area ratio is 5% or more”, and the actual survey result is 10%, the diagnostic area in which the survey means is implemented It is determined that the deterioration state of the coating film is deteriorated.

  The report output means 25 outputs the investigation result and the deterioration state of the diagnosis area in association with the address. The report output means 25 outputs the investigation result and the deterioration state of the diagnosis area to the display of the information processing apparatus 10, but is not limited to this, and is connected via a printing device such as a printer or a communication means such as the Internet. Alternatively, it may be output to another information processing apparatus. Moreover, the report output means 25 may output the information regarding the structure used as the object which diagnoses a coating film other than outputting a research result and the degradation state of a diagnostic area | region. Such information includes, for example, the name of the structure, the information of the client who requested the diagnosis, the request date and time, and the like.

  Next, a processing procedure when a coating film is diagnosed by the coating film diagnosis system will be described. FIG. 3 is a diagram illustrating a processing flow of the coating film diagnosis system according to the first embodiment. As illustrated, the information processing apparatus 10 executes six processes. First, a registration process (step S1) for registering a diagnosis region or the like of a steel structure is executed. Then, image processing (step S2) for executing image processing analysis, which is one of the investigation means, investigation result registration processing (step S3) for registering investigation results of other investigation means, and determination criteria are registered. Determination criterion registration processing (step S4) is executed. Steps S <b> 2 to S <b> 4 are not sequentially performed, but are performed in an arbitrary order according to the selection of the user of the coating film diagnosis system. Then, a determination process (step S5) for determining the deterioration state of the coating film based on these registered data is executed, and a report output process (step S6) for outputting the result is executed. Hereinafter, each process will be described in detail.

[Item information registration process]
The case information registration process is executed by the case information registration means 20, and, for example, when receiving a diagnosis request for the state of the coating film of a certain steel structure, the case information including the address of the steel structure Is registered in the database 40.

  FIG. 4 is a process flow of the case information registration process. As shown in the figure, the case information registration means 20 displays on the display an input form for inputting case information including the address and name of the steel structure, the requester information, the request date and time, etc. (step S10). Project information such as an address is input from the user of the coating film diagnosis system via a keyboard or the like (step S11). Then, the case information registration unit 20 registers the case information input in the input form in the database 40 (step S12). Table 1 shows an example of item information registered in the database 40.

  As shown in Table 1, one item information item number “1000” is registered in the database 40. The item number is a number that uniquely identifies item information. The project number “1000” has the steel structure name “storage tank 1”, the client is “XX Corporation”, the request date and time is “February 8, 2008”, and the address starts from 1. It shows that there are 9 (there are 9 diagnosis areas in the storage tank 1 in total).

[Image processing]
The image processing is executed by the image processing means 21. The image processing is processing for taking in image data of each diagnosis region of the steel structure, calculating the deterioration area rate of the diagnosis region, and registering it in the database 40.

  FIG. 5 is a processing flow of image processing. As shown in the figure, the image processing means 21 displays on the display an input form for inputting the address of the storage tank 1 and the image data of each diagnostic area of the storage tank 1 specified by the address (step S20). ). Next, the image processing means 21 captures the image data of each diagnostic area captured by the digital camera (step S21), while the address corresponding to the diagnostic area of the image data is input via the keyboard (step S21). S22). The image data and the address of the diagnostic region input in steps S21 and S22 are associated with each other (step S23), and the deterioration area rate is calculated for each address (step S24). As described above, the deterioration area rate is calculated by performing image processing such as binarization on the image data of each address, and determining that the portion exceeding the predetermined threshold is rust, cracking, peeling, and such a portion. Is calculated by calculating the ratio (deterioration area ratio) of the image data to the diagnosis area. The deterioration area rate calculated in this way is registered in the database for each address (step S25). Table 2 shows an example of the deterioration area ratio registered in the database 40.

  As shown in Table 2, for the storage tank 1 with the project number “1000”, the diagnosis area corresponding to the address “1” has a degradation area rate of “15%” due to image processing. Similarly, the address “2” has a degraded area rate of “7%”, the address “4” has a degraded area rate of “3%”, and the other addresses have a degraded area rate of “0%”. It is shown.

[Investigation result registration process]
The investigation result registration process is executed by the investigation result registration means 22 and is a process for registering the investigation results by various investigation means in the database 40 in association with the addresses.

  FIG. 6 is a processing flow of the survey result registration process. As shown in the figure, the survey result registration unit 22 displays an input form for inputting the address of the diagnostic area surveyed by the various survey units and the survey result (step S30). Next, the survey result registration unit 22 receives the address of the diagnostic area surveyed by the various survey units and the survey result via the keyboard (step S31). Then, the survey result registration means 22 registers each survey result in the database 40 in association with the address (step S32). Table 3 shows an example of various investigation results registered in the database 40 (including the degradation area rate due to image processing). Unlike Table 2, the column of “steel structure name” is omitted for the sake of display space.

  As shown in Table 3, for the storage tank 1 with the project number “1000”, various investigation means, “visually deteriorated area ratio”, “polarization resistance” (the investigation means (3 ) (Obtained by under-coating corrosion measurement), “adhesiveness” (obtained by the above-mentioned investigation means (6) adhesion investigation of coating film), “film thickness” (inspection means (5) The results of the investigation of the film thickness of the coating film) and the “coating type” (obtained by the chemical analysis of the coating film of the investigation means (4)) are shown.

  As indicated by the blanks in Table 3, it is not always necessary to register the survey results by all survey means at all addresses. In this case, the deterioration state of the coating film is determined for the address / survey means in which the survey result is registered.

[Criteria registration process]
The determination criterion registration process is executed by the determination criterion registration means 23 and is a process for registering the determination criterion in the database 40.

  FIG. 7 is a process flow of the determination criterion registration process. As shown in the figure, the determination criterion registration unit 23 displays an input form for inputting the determination criterion on the display for each investigation unit (step S40). Next, the determination criterion registration means 23 receives the determination criterion via the keyboard (step S41). Then, the criterion registration means 23 registers the criterion in the database 40 (Step S42).

  In the present embodiment, the determination criterion is that the coating film is deteriorated when the investigation result is equal to or greater than or less than the threshold value determined for each investigation means. Table 4 shows an example of the determination criteria.

  As shown in Table 4, a criterion is set for each investigation means. For example, in the case of “visually deteriorated area ratio”, if the result of the investigation is “15% or more”, the coating film in the diagnostic region targeted by the investigation means is judged to be “deteriorated”. .

[Determination process]
The determination process is executed by the determination unit 24. Based on whether or not the investigation result registered in the database 40 meets the determination criterion, the deterioration state of the diagnostic region that is the investigation target of the investigation result is determined. This is a process of determining and registering in the database 40.

  FIG. 8 is a processing flow of determination processing. As shown in the figure, the determination means 24 reads the investigation result for each address for each address from the database 40 (step S50), and then reads the determination criteria from the database 40 (step S51). Next, it is calculated whether or not each survey result meets the criterion (step S52). And based on this calculation result, the deterioration state of a coating film is determined for every investigation means about each address (step S53), and it registers into the database 40 (step S54).

  For example, in the case of the investigation result for the address “1” shown in Table 3, the “deterioration area rate due to image processing” is “15%” (step S50). On the other hand, the criterion is “Deterioration area rate by image processing is 15% or more” in Table 4 (step S51). It is calculated whether “15%”, which is the result of this investigation, meets the criterion “deterioration area rate due to image processing is 15% or more” (step S52). In this case, the difference between the investigation result “15%” and the threshold value “15%” is calculated, and if the difference is positive, the determination criterion is met. If the deterioration state is expressed by binary values of “1” (deteriorated) and “0” (not deteriorated), according to the investigation means “deterioration area ratio by image processing”, the application of the address “1” The deterioration state of the film is “1”, that is, it is determined that the film is deteriorated (step S53).

  Similarly, it is calculated whether the survey result of each address “1, 5, 9” meets the criterion of the survey means, the deterioration state of the coating film and the substrate under the coating film is determined, and registered in the database 40 (step S54). ). As a result, as shown in Tables 5 to 7, the deterioration state is determined for the address / survey means to which the survey result is input. Table 5 relates to the address “1” of the project number “1000”, Table 6 relates to the address “5” of the project number “1000”, and Table 7 relates to the address “9” of the project number “1000”.

Report output processing
The report output process is executed by the report output means 25, and is a process for outputting the investigation result and the deterioration state of the coating film and the substrate under the coating film.

  FIG. 9 is a processing flow of report output processing. As shown in the figure, the report output means 25 receives the case number to be output via the keyboard (step S60), and acquires the case information corresponding to the case number (step S61). Further, the investigation result corresponding to the case number, the deterioration information of the coating film and the substrate under the coating film are acquired (step S62). Then, the item information, the investigation result of the coating film and the base material of the coating film, and the deterioration information of the coating film and the base material of the coating film are shaped into a predetermined format and displayed on the display (step S63). For example, when “1000” is input as the case number, the case information of the case number “1000” shown in Table 1, the survey results for each address shown in Tables 5 to 7, and the deterioration state of the coating film are displayed. Is displayed. Of course, the deterioration state may not be displayed as “1” or “0” but may be displayed as words such as “deteriorated” or “not deteriorated”.

  In the coating film diagnosis system described above, the outer wall surface of the storage tank 1 to be diagnosed is divided into diagnosis areas, and investigation results are obtained for each diagnosis area, and the investigation results conform to the judgment criteria. The deterioration state of the coating film in the diagnostic region is determined depending on whether or not to do so.

  On the other hand, since the environmental conditions differ from part to part, the structure may be partially degraded even if it is a good overall film. Even in such a case, since the deterioration state of the coating film in the diagnostic area and the base material under the coating area is determined by dividing the outer wall surface of the structure, the deterioration is partially avoided without overlooking the coating film on which rust or peeling has occurred. The state can be determined. Incidentally, for example, when image data obtained by imaging the entire outer wall surface of the storage tank 1 with a digital camera is subjected to image processing to obtain a deteriorated area rate, it is determined that the entire outer wall surface is good even if a deteriorated portion exists. However, this is not the case with the coating film diagnosis system of the present invention.

  Moreover, the deterioration state of each diagnostic area | region was determined from the investigation result obtained by implementing several investigation means in each diagnostic area | region. Thus, for example, even if a certain investigation means is difficult to implement due to the location of the structure, the positional relationship with other structures, and the shape of the structure, other investigation means should be implemented. Thus, the investigation result of the diagnosis area can be acquired and the deterioration state can be determined. For example, since there is a shield in front of the addresses “4” and “7” of the storage tank 1, the diagnosis area of the addresses “4” and “7” is difficult to investigate with a digital camera, but it is like under-coating corrosion measurement. In particular, electrochemical measurement means can be easily investigated by coating film diagnosis. In short, since the coating film diagnosis system according to the present embodiment is divided into a plurality of diagnosis areas, it is possible to implement investigation means suitable for each diagnosis area, so that the installation location of the structure and other structures It has the flexibility that the deterioration state of the coating film can be determined without being influenced by factors such as the positional relationship.

In the coating film diagnosis system according to the first embodiment, the deterioration state of the coating film and the base material of the steel structure to be diagnosed is finally determined for each investigation means. Furthermore, it is suitable for calculating the comprehensive judgment indicating whether or not the diagnosis area specified by the address is deteriorated from the deterioration state for each investigation means, and repairing the steel structure based on the comprehensive judgment. The recommended painting specifications are output.

  FIG. 10 is a schematic configuration diagram of a coating film diagnosis system according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same thing as Embodiment 1, and the overlapping description is abbreviate | omitted. As shown in the figure, the coating film diagnosis system according to the second embodiment includes an overall determination unit 26, a substrate adjustment method registration unit 27, a coating specification registration unit 28, a desired coating information acquisition unit 29, and a recommended coating specification extraction unit. 30 is different from the first embodiment.

  The comprehensive determination unit 26 calculates a comprehensive determination from the deterioration state determined by the determination unit 24. The deterioration state indicates the degree of deterioration of the coating film and the substrate under the coating film for each investigation means, but the comprehensive judgment indicates the degree of deterioration of the coating film in the diagnosis area specified by each address. It is. That is, according to the comprehensive determination, a comprehensive degree of deterioration of the coating film and the substrate under the coating in the diagnosis region can be obtained.

  Specifically, the comprehensive determination is calculated as follows. First, a total score is calculated by multiplying and adding a predetermined weighting factor to the deterioration state of the coating film and the substrate under the coating film for each investigation means. If the total score exceeds a predetermined threshold, the diagnosis area specified by the address is assumed to be degraded. If the threshold is not exceeded, the diagnosis area is not degraded.

  Note that a plurality of threshold values may be set and the degree of deterioration may be set in a plurality of stages. For example, “the deterioration degree is large when the total score exceeds 2”, “the deterioration level is medium when the total score exceeds 1 and 2 or less”, and “no deterioration is generated when the total score is 1 or less”.

  The substrate adjustment method registration unit 27 registers the substrate adjustment method defined for each degree of deterioration of the coating film and the substrate under the coating area in the diagnosis area in the database 40. Here, the substrate adjustment method refers to the work content performed on the diagnosis area prior to the repair painting of the diagnosis area of the storage tank 1. The substrate adjustment method is defined for each degree of deterioration of the coating film and the substrate under coating, if the degree of deterioration of the coating film and the substrate under coating is determined, the substrate adjustment method to be applied is determined. .

  The paint specification registration means 28 registers the paint specification including the paint name and the paint method in the database 40 in association with the combination of the substrate adjustment method and the paint information. The painting information is information relating to the property of painting that is determined in advance and is used for repair painting of the diagnostic area. Although details will be described later, the painting information is used to reflect the desire of the person who requests the painting of the storage tank 1 as to what kind of property is used as the painting used for the storage tank 1.

  For example, the painting information includes “the type of the old paint film that has already been painted in the past”, “whether the same paint film as the old paint film is repaired,” “whether it is an environmentally-friendly paint,” “ It consists of a set of possible values for each item such as “whether it is a painting process with a reduced process” and “whether it is a highly durable coating”. Table 8 shows an example of paint information.

  As shown in Table 8, the old coating film can take values of “phthalic acid type” and “chlorinated rubber type”, for example. Similarly, "Whether the same coating as the old paint film is repaired or not", "Whether it is an environmentally-friendly coating", "Whether it is a coating method with a reduced process" and "High durability coating" As for “whether or not,” one of the two values “◯” and “×” can be taken.

  And the combination of the value which such painting information can take and each substrate adjustment method is created, and each combination is related with the painting specification. Table 9 shows an example in which the coating specification is associated with the combination of the substrate adjustment method and the coating information when the type of the substrate adjustment method is “1 type” and “2 types”.

  As shown in Table 9, for example, the “type” of the substrate adjustment method is “1 type”, the “old paint film” of the paint information is “phthalic acid type”, and “the same thing as the old paint film is repaired” If “painted” is “× (same thing is not repair painted)”, “environmental response” is “○”, “saving process” is “○”, and “high durability” is “○” It shows that the code of the coating specification used sometimes is “1-1-7”. That is, if the substrate adjustment method and the painting information are specified, one painting specification is determined. In this way, the painting specification registration means 28 registers one painting specification in the database 40 for all combinations of the substrate adjustment method and the values that the painting information can take. In the example shown in Table 9, only the code is shown for the coating specification, but it is assumed that a specific paint name and coating method are registered in the database 40 for each code.

  Specifically, the desired painting information acquisition means 29 interviews a person who requests the painting of the storage tank 1 with regard to what kind of property is used as the painting used for the storage tank 1, and obtains the result. Obtained via input means such as a keyboard.

  The recommended paint specification extraction means 30 matches the desired paint information among the base material adjustment method corresponding to the degree of deterioration of the coating film in the diagnosis area determined by the comprehensive determination means 26 and the paint information registered in the database 40. The one corresponding to the combination with the painting information is extracted from the database 40 as the recommended painting specification. That is, the substrate adjustment method to be performed in the diagnosis area is selected according to the degree of deterioration of the coating film in the diagnosis area, and the painting specification that matches the painting information desired by the person requesting the painting is selected. .

  Next, a processing procedure when a coating film is diagnosed by the coating film diagnosis system according to the second embodiment will be described. FIG. 11 is a diagram illustrating a processing flow of the coating film diagnosis system according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same process as Embodiment 1, and the overlapping description is abbreviate | omitted. As illustrated, in the information processing apparatus 10, six processes are newly added from the first embodiment. First, the registration process (step S1) which registers the diagnostic area | region of a steel structure, etc. similarly to Embodiment 1 is performed. Then, image processing (step S2) for executing image processing analysis, which is one of the investigation means, investigation result registration processing (step S3) for registering investigation results of other investigation means, and determination criteria are registered. Determination criterion registration processing (step S4) is executed. Further, in the second embodiment, a base material adjustment method registration process (step S4-2), a paint specification registration process (step S4-3), and a desired paint information acquisition process (step S4-4) are executed. Steps S <b> 2 to S <b> 4 and S <b> 4-2 to S <b> 4-4 are not sequentially performed, but are performed in an arbitrary order according to the selection of the user of the coating film diagnosis system. And after the determination process (step S5) which determines the deterioration state of a coating film based on these registered data is performed, comprehensive determination process (step S5-2) and recommended coating specification extraction process (step S5-3) ) Is executed, and a report output process (step S6) for outputting the result is executed. Hereinafter, each process will be described in detail.

[Base adjustment method registration process]
The substrate adjustment method registration process is executed by the substrate adjustment method registration unit 27 and is a process of registering the substrate adjustment method in the database 40.

  FIG. 12 is a processing flow of the substrate adjustment method registration processing. As shown in the figure, the substrate adjustment method registration means 27 displays an input form for inputting the substrate adjustment method for each degree of coating film deterioration on the display (step S70). Next, the substrate adjustment method registration means 27 receives the substrate adjustment method via the keyboard (step S71). Then, the substrate adjustment method registration unit 27 registers the substrate adjustment method in the database 40 in association with the degree of deterioration of the coating film and the substrate under the coating film (step S72). Table 10 shows an example of the substrate adjustment method defined for each degree of deterioration of the coating film and the substrate under the coating film.

  In Table 10, for example, if the degree of deterioration of the coating film and the base material under the coating film is “large deterioration degree”, “1 type” “rust, coating film is removed, It is shown that the method of “steel surface” is associated.

[Painting specification registration process]
The paint specification registration process is executed by the paint specification registration means 28, and the paint specification including the paint name and the paint method is registered in the database 40 in association with the combination of the paint information and the substrate adjustment method.

  FIG. 13 is a process flow of the paint specification registration process. As shown in the figure, the paint specification registration means 28 displays an input form for inputting the paint specification on the display (step S80). Next, the paint specification registration means 28 receives the paint specification via the keyboard (step S81). Then, the coating specification registration means 28 associates the coating specification input in step S81 with the combination of the predetermined coating information and the substrate adjustment method registered in the substrate adjustment method registration process, and registers them in the database 40 (step S82). ). Thereby, as shown in Table 9, the painting specification is registered in the database 40 in association with the painting information and the substrate adjustment method.

[Request painting information acquisition process]
The desired paint information acquisition process is executed by the desired paint information acquisition means 29, and is a process for acquiring desired paint information relating to the properties of the paint to be used when repairing the diagnostic area.

  FIG. 14 is a processing flow of desired coating information acquisition processing. As shown in the figure, the desired painting information acquisition unit 29 displays an input form for inputting the project number and the desired painting information on the display (step S90). Next, the desired paint information acquisition means 29 receives the project number and the desired paint information via the keyboard (step S91). Then, the desired painting information acquisition means 29 registers the desired painting information in the database 40 in association with the project number (step S92). As a result, the request from the client regarding the painting used in the diagnosis area requiring repair painting is registered in the database 40 for a certain project number.

  For example, as desired paint information, "Old paint film is chlorinated rubber", "Do not use the same as the old paint film", "Use environmentally friendly", "No need for process savings", " It is assumed that “use a highly durable material” is input.

  Next, although the determination process of step S5 is performed, since the process content is the same as that of Embodiment 1, description is abbreviate | omitted, and the deterioration of the coating film and subbing | coated base material about each address like Table 5-Table 7 Suppose the state is obtained.

[Comprehensive judgment processing]
The comprehensive determination process is executed by the comprehensive determination means 26, and is a process of calculating a comprehensive determination from the deterioration state of the coating film and the base material under the coating film for each addressing means registered in the database 40.

  FIG. 15 is a process flow of the comprehensive determination process. As shown in the figure, the comprehensive judgment means 26 acquires the deterioration state of the coating film and the base material under the coating film for each investigation means from the database 40 for each address (step S100). For example, it is assumed that the deterioration state of the coating film and the base material under the coating film shown in Table 5 is acquired.

Next, the total points are calculated by multiplying and adding the respective weighting factors to the deterioration states of these coating films and the substrate under the coating films (step S101). That is, “deterioration state obtained from visual degradation area ratio” is X ₁ , “degradation state obtained from degradation area ratio by image processing” is X ₂ , and “degradation state obtained from polarization resistance” is X _3. If the “degraded state obtained from adhesion” is X ₄ and the “degraded state obtained from film thickness” is X ₅ , the total point Y is obtained by the following equation. In the following formula, a to e are predetermined weighting factors.

Next, based on the value of the total point Y, the degree of deterioration (overall determination) of the coating film and the substrate under the coating area in the diagnosis region is calculated (step S102). Specifically, a threshold value is provided, and the degree of deterioration is calculated based on whether or not the total point Y exceeds the threshold value. For example, using a plurality of threshold values t _{0 to} t ₂ , if the total point Y is 0 or more and less than t ₀ , the comprehensive determination is “sound”, and if it is t ₀ or more and less than t ₁ , the comprehensive determination is “degradation degree”. If it is “small”, t ₁ or more and less than t ₂ , the comprehensive judgment can be “medium degree of deterioration”, and if it is t ₂ or more, the comprehensive judgment can be “high degree of deterioration”.

  For example, in order to increase the specific gravity with respect to the deterioration area ratio and the polarization resistance by visual and image processing, the predetermined weighting coefficient is “2 for a, b, and c” and “1 for d and e”. Further, for example, if the overall score Y is 0 or more and less than 1.5, the threshold for the comprehensive judgment is “sound”, and if it is 1.5 or more and less than 3, “deterioration degree is low”, 3 or more and 4.5 If it is less than “deterioration degree”, “deterioration degree is medium”, and if it is 4.5 or more, “deterioration degree is large”. From the deterioration state of the addresses “1, 5, 9” in Tables 5 to 7 and the predetermined weighting factor, the overall point Y1 for the address “1” and the overall point for the address “5” as shown in the following equation: The total point Y9 for Y5 and the address “9” can be calculated.

  Table 11 shows the overall judgment calculated from these overall points Y1, Y5, Y9 and the threshold values.

  In this way, comprehensive determination is calculated for each address, and these comprehensive determinations are registered in the database 40 (step S103).

  The predetermined weighting factor may be determined according to the type of coating applied to the diagnostic area. For example, in a weak coating film such as an alkyd system, deterioration such as rust is likely to occur on the surface, and therefore a coefficient related to the deterioration area ratio is set large. On the other hand, a strong coating film such as an epoxy type or a thick coating type does not show deterioration on the surface, and peeling may proceed under the coating film, so the coefficient related to the polarization resistance is set large. Thereby, an appropriate comprehensive determination can be made according to the coating film.

[Recommended paint specification extraction process]
The recommended paint specification extraction process is executed by the recommended paint specification extraction means 30 and corresponds to a combination of the base information adjustment method and the paint information that matches the desired paint information among the paint information registered in the database 40. A thing is extracted from the database 40 as a recommended painting specification.

  FIG. 16 is a processing flow of recommended painting specification extraction processing. As shown in the figure, the recommended paint specification extracting means 30 extracts a substrate adjustment method suitable for comprehensive determination of each address from the substrate adjustment methods registered in the database 40 (see Table 10) (step S110). For example, for the address “1” in Table 11, the overall determination is “high degradation level”, and therefore, in Table 10, the substrate adjustment method having the type “1 type” is extracted. Further, for the address “9” in Table 11, since the comprehensive determination is “medium degree of degradation”, the base adjustment method with the type “2 types” is extracted from Table 10. For the address “5”, since the comprehensive determination is “sound”, the base adjustment method is not particularly extracted.

  Next, among the combinations of the substrate adjustment method and the paint information shown in Table 9, the paint information that corresponds to the substrate adjustment method extracted in step S110 and matches the desired paint information acquired in the desired paint information acquisition process Is searched (step S111).

  The desired paint information includes "Old paint film is chlorinated rubber", "Do not use the same paint film as the old paint film", "Use environmentally friendly product", "No need for process savings", "High Since “use durable ones” is input, the combinations shown in Table 12 among the combinations shown in Table 9 are searched for the addresses “1” and “9”.

  Next, a painting specification corresponding to the combination of the found substrate adjustment method and painting information is set as a recommended painting specification (step S112). In the case of the example in Table 12, as the coating specification, the recommended coating specification is the paint and the coating method specified by the code “1-2-6”. In this way, the paint information that matches the desired paint information is retrieved and becomes the recommended paint specification, so that it is possible to reflect the desire of the person who has requested the diagnosis of the painting of the storage tank 1.

  Then, in the report output process, as shown in Table 13, the comprehensive judgment, item information, survey results, and the like including this recommended paint specification are shaped into a predetermined format and output on the display.

  In the coating film diagnosis system described above, the outer wall surface of the storage tank 1 to be diagnosed is divided into diagnosis areas, and investigation results are obtained for each diagnosis area, and the investigation results conform to the judgment criteria. The deterioration state of the coating film in the diagnosis region is determined depending on whether or not to perform, and comprehensive determination is calculated for each diagnosis region from the deterioration state, and the recommended coating specification is output by this comprehensive determination.

  Thus, after dividing the outer wall surface of the storage tank 1 into a plurality of diagnostic areas, the recommended coating specifications are calculated for each diagnostic area. Therefore, the storage tank 1 is applied with appropriate coating for each diagnostic area according to the recommended coating specifications. The outer wall of the steel structure such as can be kept good. In particular, although the coating on the entire outer wall surface is good, even if a certain diagnosis area is deteriorated, a recommended coating specification suitable for the diagnosis area can be obtained.

  In addition, as described in the first embodiment, since the coating film diagnosis system according to the present embodiment is divided into a plurality of diagnosis areas, it is possible to carry out investigation means suitable for each diagnosis area. Determine the deterioration state of the paint film and the base material under the paint film without being influenced by factors such as the installation location and the positional relationship with other structures, and make a comprehensive judgment based on this deterioration state to obtain the recommended paint specifications It has the flexibility of being able to

  Furthermore, since the information processing apparatus 10 is the main body and the overall determination is calculated, an objective determination that does not depend on the allegation of the painter can be performed quickly, and the recommended coating specification is determined based on the overall determination. Since it is output, even a painter with little experience can perform painting work maintaining a certain quality.

<Embodiment 3>
In the coating film diagnosis system according to the first embodiment and the second embodiment, nine diagnosis areas are set in advance, and the number, size, position, and shape thereof are fixed. May be set or corrected according to the above.

  FIG. 17 is a schematic configuration diagram of a coating film diagnosis system according to the third embodiment. In addition, the same code | symbol is attached | subjected to the same thing as Embodiment 1, Embodiment 2, and the overlapping description is abbreviate | omitted. As shown in the drawing, the coating film diagnosis system according to the third embodiment is different from the second embodiment in that it further includes a diagnosis region setting unit 31 and a diagnosis region resetting unit 32.

  The diagnosis area setting means 31 first acquires the deterioration area rate for the temporary diagnosis area provided with the coating film of the steel structure, and re-divides the temporary diagnosis area whose deterioration area ratio is a predetermined value or more to diagnose the diagnosis area And At the time of re-segmentation, a boundary line that divides the diagnostic region is added to the image data obtained by imaging the steel structure and output to the output device. As a result, a diagnosis area to be newly surveyed is presented to the person who conducts the survey. Further, the case information (see Table 1) is registered in the database 40 so that the diagnosis area is uniquely identified by the address.

  Thereby, in the initial setting of the diagnosis area, the diagnosis area is automatically set in consideration of the deterioration area rate of the coating film of the current steel structure. As described in the first and second embodiments, the deterioration area ratio is acquired by the survey result registration unit 22 or the image processing unit 21.

  The method of re-segmentation may be appropriately set with respect to the number, position, size, and shape. In particular, the provisional diagnosis area whose deterioration area rate is a predetermined value or more is relatively finely divided, and the other provisional diagnosis areas are classified. It is preferable to divide relatively large. As a result, a fine diagnostic region is set for a portion where the degree of deterioration is large, and a large diagnostic region is set for a portion where the degree of deterioration is small. For this reason, places where the degree of deterioration is large are intensively investigated by each investigation means, and places where the degree of deterioration is small can be simply investigated. In this way, the investigation by the later investigation means can be rationalized.

  The diagnosis area resetting means 32 repartitions the diagnosis area that is deteriorated from a predetermined standard based on the comprehensive judgment calculated by the comprehensive judgment means 26 into a plurality of new diagnostic areas, and uniquely assigns them by address. The item information in the database 40 is corrected so as to be identified. Although it is the same as the diagnostic area setting means 31 in that the diagnostic area is re-segmented, the diagnostic area resetting means 32 is characterized by appropriately re-dividing the diagnostic area based on the comprehensive determination.

  Specifically, first, a diagnosis region in which the degree of deterioration is equal to or greater than a predetermined reference is specified based on the comprehensive determination. For example, if the predetermined criterion is “high degradation level”, the diagnosis area of the address “1” in Table 11 is specified. For example, the diagnosis information is divided into three equal parts to update the case information. Table 14 shows the updated item information.

  The diagnosis area specified by the address “1” is divided into three, and addresses “1a”, “1b”, and “1c” that specify each diagnosis area are registered. Thereafter, as shown in Table 15, each investigation means is implemented including the divided diagnostic areas. Thereafter, in the same manner as in the first and second embodiments, each process is performed on the newly re-divided diagnosis area, and the deterioration state, comprehensive determination, recommended coating specification, and the like are calculated and output.

  The re-segmented diagnostic area is output to the output device by adding a boundary line that classifies the new diagnostic area to the image data obtained by imaging the steel structure. As a result, a diagnosis area to be newly surveyed is presented to the person who conducts the survey.

  The method of re-segmentation may be set as appropriate for the number, position, size, and shape, but in particular, the diagnosis area whose comprehensive judgment is a predetermined value or more is relatively finely divided, and the other diagnosis areas are relatively It is preferable to divide it roughly. As a result, when a diagnosis area that easily deteriorates due to factors such as aging occurs, the diagnosis area is finely re-divided, and the subsequent investigation can be performed closely, and a more accurate coating film and sub-coating substrate Can be diagnosed. In this way, every time a survey is performed and a comprehensive determination is calculated, the number, position, size, and range of diagnosis areas are changed according to the degree of deterioration. That is, the diagnostic region can be followed according to the secular change.

  Since the diagnosis area is dynamically changed in this way, it is possible to conduct an efficient investigation in which a diagnosis area that is likely to deteriorate can be investigated closely and a diagnosis area that is difficult to deteriorate can be investigated roughly. In addition, since the region that is likely to deteriorate is closely investigated, it is possible to diagnose the state of the coating film and the substrate under the coating more accurately.

<Other embodiments>
In the first, second, and third embodiments described above, the diagnosis region of the steel structure is specified by the address. However, the present invention is not limited to this, and the address may be configured hierarchically. For example, “Item number” that uniquely identifies a plurality of steel structures, “Parts” that uniquely identify a plurality of parts of one steel structure, for example, top, side, back, etc. It is good also as "address" which identifies the diagnostic area | region uniquely. Table 14 illustrates hierarchical addresses.

  Even in such a case, the investigation means may be implemented for each diagnosis area specified by each case number, each part, and each address, and the deterioration state, comprehensive judgment, and recommended coating specification may be calculated.

  In the first and second embodiments described above, the deterioration state or the like is determined for one investigation result obtained by performing the investigation means once for each diagnosis area. The deterioration state or the like may be determined based on a plurality of survey results obtained by performing the above. Table 17 exemplifies the investigation results obtained by conducting the investigation means twice for the diagnosis region identified by the address “1”.

  In such a case, a deterioration state is calculated for each investigation result, and a comprehensive point (see [General determination processing]) is calculated from the deterioration state for each investigation result. Thereafter, for example, the average of the total points for each survey result is taken. Then, a comprehensive determination can be calculated based on whether this average exceeds a predetermined threshold.

  Moreover, although the cylindrical storage tank 1 was demonstrated to the example as a steel structure, of course, it is not limited to a storage tank, The coating-film diagnostic system which concerns on this invention can apply widely to various structures It is.
