Description

Data acquisition system and method for evaluating the aging level of facilities {DATA COLLECTING SYSTEM FOR EVALUATING DETERIORATED LEVEL OF FACILITY, AND METHOD FOR THE SAME}

The present invention relates to the evaluation of the aging level of a facility, and more specifically, when evaluating the level of aging of a facility such as bridges, tunnels, dams, retaining walls, buildings, etc. It relates to a data securing system and method for evaluating the aging level of a facility that secures aging related data.

In general, facilities are classified into structures made through construction work and their facilities, and are classified into first class facilities and second class facilities. For example, first class facilities are roads, railways, ports, dams, bridges, tunnels, buildings, etc. Refers to facilities that need to be specially managed to promote convenience and safety of users, or are facilities that have been recognized to require advanced technology for structural maintenance. Class 2 facilities refer to facilities other than class 1 facilities.

By quickly and accurately investigating and evaluating the risk factors, facility function and performance degradation, and conditions inherent in these facilities, taking appropriate safety measures to prevent disasters and disasters, and supplementing and preserving facility safety and functionality In order to promote the utility of facilities and systematize scientific maintenance, it is necessary to check facility safety and precise safety diagnosis.

In Korea, major infrastructure began to be built intensively in the 1970s, and facilities that have been in operation for more than 30 years have been rapidly increasing. For example, as of 2014, among the first and second facilities in the "Special Act on the Safety Management of Facilities", 9.6% of facilities aged 30 years or more after completion, but will increase to 21.5% more than double in 2024. Is expected.

Nevertheless, in Korea, there is no way to systematically evaluate the degree of aging of facilities. Moreover, many researchers set the facility's aging standard as 30 years of public use, but there is no clear basis for this. In addition, even at the same facility, the design and materials at the time of construction are different, and the degree of aging varies depending on the location environment and maintenance conditions. Therefore, there is a problem in that it is inaccurate to determine the degree of aging of facilities collectively based on the number of years of public use.

Meanwhile, in Korea, there are about 33,500 bridges and about 2,300 tunnel facilities. In addition, there are various facilities such as retaining walls and dams. In order to evaluate the aging level of a facility through the method for evaluating the aging level of the facility, time history data for the measurement details of the facility is essential.

However, because of the large number of facilities, there is a problem that it takes a lot of evaluation time and evaluation cost to secure all of these data. Therefore, there is a need for a method to efficiently evaluate the aging level of many facilities.

Specifically, the system for evaluating the aging level of a facility collects detailed indicator measurements by measuring the detailed indicators of the facility, and then calculates the aging and comprehensive aging for each member according to the weight of the detailed indicator and the Accelerated Aging Index (AAI). In addition, it is possible to evaluate the level of aging of a facility through a relative comparison between the calculated value of the overall aging degree and the actual number of public years of the facility. For example, the aging degree of a facility can be evaluated by comparing the calculated aging degree of the facility with the design life, and comparing with the aging number of years and the number of public years of the facility at the time of evaluation.

Referring to FIG. 2, in the case of a data securing system for evaluating the aging level of a facility according to an embodiment of the present invention, the entire facility 200 is primarily classified into the same facility by type, such as bridges, tunnels, dams, retaining walls, buildings, etc. In addition, the same facilities for each type are classified according to classification conditions such as type, environmental conditions, and traffic volume, and are secondarily classified as identical facilities according to classification conditions. In addition, the representative facilities 210 are selected from the same facilities according to the classification conditions, and the same facilities according to the classification conditions other than the representative facilities 21 are the evaluation facilities 220 for evaluating the aging level.

(동결융해 6단계) = 108단계 구역으로 분류할 수 있다. 물론, 비래염분, 제설제 및 동결융해 이외에도 습도 등 시설물 분류에 필요한 다양한 항목들을 고려할 수 있다는 점은 당업자에게 자명하다.Specifically, among the entire facilities, the first classified bridges are classified by type, for example, considering the type of bridge, environmental conditions in which the bridge is located, and traffic volume. For example, the environmental conditions where the bridge is located can be classified into a total of 108 zones in consideration of flying salinity, snow removing agents and freeze-thaw. Specifically, in order to classify the entire area into 108 zones, the nasal salt is considered as 3 stages, the snow removal agent is considered as 6 stages, and freeze-thawing 6 stages, respectively.

(Snow removal agent step 6)

(Step 6 of Freezing and Melting) = It can be classified as step 108. Of course, it is apparent to those skilled in the art that various items necessary for classification of facilities, such as humidity, salt removal, and freeze-thawing, may be considered.

The representative facility selection and data securing unit 120 includes a representative facility selection unit 121, a representative facility time history data collection unit 122, and a representative facility time history data construction unit 123, the same facilities by classification conditions. Select the representative facility 210 from among them, collect the time history data for the items related to old age-related detailed indicators for the representative facility 210 only, and periodically measure the old age-related detailed indicators for the selected representative facility, Time history data is constructed by collecting and accumulating each data. Here, the detailed index items may include, but are not limited to, the neutralization depth of concrete, the surface strength of concrete, the crack width of concrete, the deflection of members, or the slope of members.

Specifically, the representative facility selection unit 121 selects the representative facility 210 from the same facilities according to the classification conditions included in the area classified by the classification conditions such as type, environmental condition, and traffic volume. At this time, the representative facility 210 is selected according to a predetermined selection criterion, and the type and characteristics of the facility 200 are reflected as the selection criterion. For example, the selection criteria may be detailed items such as the number of years of use, span length, route type, facility installation direction (azimuth angle), and height from sea level, and such items are prioritized, and the representative facility 210 Can be selected according to the priority of the selection criteria. At this time, it is obvious to those skilled in the art that other related indicators may be considered in addition to the detailed items suggested as the selection criteria.

The representative facility time history data collection unit 122 collects time history data for the detailed indicator items related to old age only for the representative facility 210.

The representative facility time history data construction unit 123 periodically measures detailed indicators related to aging on the selected representative facility and collects and accumulates each data to build time history data.

Referring back to FIG. 3, the representative facility aging level evaluation unit 130 may evaluate the aging level (aging degree) according to the facility aging evaluation method for the representative facility on which the time history data is constructed.

The evaluation facility data securing unit 140 includes an evaluation facility selection unit 141 and an evaluation facility time history data estimation unit 142, which are the same for each classification condition without time history data not selected as the representative facility 210. As the facilities 220, the time history data is estimated and secured by utilizing the time history data of the representative facility 210.

The evaluation facility selection unit 141 selects the evaluation facility 220 from among other facilities that do not have time history data not selected as the representative facility 210 in the same facility setting unit 112 according to the classification conditions.

The evaluation facility time history data estimating unit 142 secures data by estimating the time history data of the evaluation facility 220 by utilizing the time history data of the representative facility 210. That is, among the same facilities according to the classification conditions, the evaluation facility 220 other than the representative facility 210 may be estimated by using the time history data of the representative facilities 210 classified under the same conditions for evaluating the aging level. You can.

Referring back to FIG. 3, the evaluation facility aging level evaluation unit 150 evaluates the aging level by calculating weights and detailed acceleration index (AAI) for each detailed index of the evaluation facility 220 in which the time history data is estimated, Accordingly, it is possible to evaluate the aging level of the same facility according to different classification conditions. Here, the Aging Acceleration Index (AAI) represents the change in the rate of aging progression by the time history data of the corresponding detailed indicator.

In addition, the same facilities for each type can be classified into the same facilities for each classification condition, as described above, and then each representative facility can be selected to evaluate the aging level of the same facilities for all classification conditions.

On the other hand, Figure 4 is a view for explaining a representative facility aging level evaluation in a data acquisition system for evaluating the aging level of facilities according to an embodiment of the present invention.

As shown in FIG. 4, in the data securing system for evaluating the aging level of a facility according to an embodiment of the present invention, the representative facility aging level evaluation unit 130 includes an aging-related data analysis unit 131, an aging-related DB ( 132), detailed indicator weight setting unit 133, detailed indicator aging acceleration index setting unit 134, member aging calculation unit 135, member weight setting unit 136, comprehensive aging calculation unit 137 And an aging training and level evaluation unit 138. At this time, the representative facility 210 includes first to n-th members 211 to 213.

The aging-related data analysis unit 131 displays detailed indicator measurement values for the members 211, 212, and 213 of the representative facility 210 according to the initial state (design value) and the limit state of the member, and the aging of the detailed index measurement values. Analyze the level. At this time, detailed index items for the first to n-th members 211 to 213 may include neutralization depth of concrete, surface strength of concrete, crack width of concrete, deflection of members, and slope of members.

The aging-related DB 132 stores the initial state (design value) and limit state of the material and member, and stores the set weight and the aging acceleration index. At this time, the aging acceleration index (AAI) represents the change in the aging progress rate by the time history data of the corresponding detailed indicator.

The detailed indicator weight setting unit 133 sets the weight for each detailed indicator, and the detailed indicator aging acceleration index setting unit 134 sets the aging acceleration index for each detailed indicator. At this time, the aging acceleration index for each detailed index is calculated periodically based on the measurement period.

The aging degree calculation unit 135 for each member calculates the aging degree for each member of the aging level evaluation facility 200 for the analyzed detailed indicator measurement value according to the weight for each metric and the aging acceleration index for each metric (AAI). .

The weight setting unit 136 for each member sets weights for the members so as to calculate the age of the members by combining data by analyzing the measured values of detailed indicators related to the oldness of each member. Specifically, the weight setting unit 136 for each member classifies the members 211 to 213 of the representative facility 210 according to the types and characteristics of the members 211, 212, and 213 when calculating the age of each member. The oldness of the corresponding members 211, 212, 213 is calculated by combining the data by analyzing the measured values of detailed indicators related to the oldness of the members 211, 212, 213.

The comprehensive aging degree calculation unit 137 calculates the overall aging degree of facilities by synthesizing the aging degrees for each member.

The aging training and level evaluation unit 138 evaluates the aging level of the facility through a relative comparison between the calculated total aging degree value and the actual public years of the facility.

Accordingly, the overall aging degree of the calculated facilities can be compared with the design life, and expressed as aging years, and the aging years and the aging level can be evaluated by comparing the aging years with the public years of the facilities at the time of evaluation.

Meanwhile, FIG. 5 is a view for specifically explaining the evaluation of the aging level of the evaluation facility in the data securing system for evaluating the aging level of the facility according to an embodiment of the present invention.

Referring to FIG. 5, in the data securing system for evaluating the aging level of a facility according to an embodiment of the present invention, the evaluating facility aging level evaluation unit 150 includes an aging-related data analysis unit 151 and an aging-related DB 152 , Detailed indicator weight setting unit 153, detailed indicator aging acceleration index setting unit 154, member aging calculation unit 155, member weight setting unit 156, comprehensive aging calculation unit 157, and aging And a training and level evaluation unit 158.

At this time, when the evaluation facility aging level evaluation unit 150 is compared with the representative facility aging level evaluation unit 130, the representative facility aging level evaluation unit 130 is only the representative facility 210, the detailed indicators related to aging. After collecting time history data for the item, time history data is constructed by periodically measuring detailed indicators related to aging on the selected representative facilities and collecting and accumulating each data.

On the other hand, the evaluation facility aging level evaluating unit 150 analyzes the detailed indicator measurement value only once, and the evaluation facility (according to the representative facility time history data constructed by the representative facility time history data building unit 12) Except for estimating the time history data for 220), the operation of the representative facility aging level evaluation unit 130 and the evaluation facility aging level evaluation unit 150 is substantially the same, so a detailed description thereof will be omitted.

Meanwhile, FIGS. 6A and 6B are diagrams illustrating calculating concrete neutralization aging and concrete surface strength aging as aging for each measurement item in a data securing system for evaluating the aging level of facilities according to an embodiment of the present invention, respectively. to be.

When the measured value of the detailed indicator obtained through the measurement of the detailed indicator items described above is the same as the initial state (design value), the aging level is regarded as not progressing, and the aging level is evaluated as "0 (Zero)". In addition, when the measured value of the detailed indicator is the same as the limit state, the aging level is regarded as the maximum, and the aging level is evaluated as “100”.

For example, when the detailed index is "depth of neutralization of concrete", the initial state is "0 mm" and the limit state is "depth of coated concrete (mm)". At this time, the detailed index measurement value obtained by measuring the "neutralization depth of concrete" through measurement may be expressed as the depth of the neutralized concrete (mm) from the concrete surface. Accordingly, the aging level (aging degree) for each measurement item may be expressed as Equation 1 below by converting the detailed index measurement value into a relative value in a range of an initial state and a limit state. Hereinafter, the level of aging refers to the same term as deterioration.

For example, as shown in FIG. 6A, when the measured value of “concrete neutralization depth” is 10 mm in a concrete covering of 40 mm, the “concrete neutralization” aging degree for the corresponding member of the aging level evaluation facility is It can be calculated as in Equation 2.

In addition, as shown in FIG. 6B, when the surface strength measurement value is 26 MPa for concrete having a design reference strength of 28 MPa, the “concrete surface strength” aging degree in the corresponding member may be calculated as in Equation 3 below.

Here, the 85% level of 28MPa, which is the initial state, is applied as the limit state.

Meanwhile, the method of securing data of the same facility according to the classification conditions without time history data will be described in detail as follows.

7A and 7B are diagrams illustrating a model of "years of public-age" for concrete neutralization aging in a data acquisition system for evaluating aging levels of facilities according to an embodiment of the present invention, respectively. In addition, FIGS. 8A and 8B are diagrams illustrating a model of “years of public-age” for concrete surface strength in a data acquisition system for evaluating the aging level of facilities according to an embodiment of the present invention, respectively.

First, among the same facilities according to the classification conditions, the evaluation facilities 220 other than the representative facilities 210 are representative facilities 210 classified under the same conditions so as to calculate the weight and the accelerated aging index (AAI) for each detailed index for evaluating the aging level. The aging level (aging degree) can be evaluated by estimating the time history data using the time history data of.

7A and 7B, as shown in FIGS. 8A and 8B, the solid blue line represents the time history data of the representative facility, and the red dot is the detail measured in the evaluation facility 220 to be evaluated without the time history data. Shows the level of aging (aging) by indicator measurements. At this time, the detailed indicators exemplify the cases of neutralizing concrete and surface strength of concrete, respectively.

The time history model of the evaluation facility 220 is estimated through the type of time history of the representative facility 210 and the measured value analysis of the evaluation facility and the old point (0, 0). That is, the time history model of the evaluation facility 220 other than the representative facility 210 may be estimated as indicated by the black broken line.

Through the estimated time history model (black dashed line), it is possible to calculate the weights and the aging acceleration index (AAI) for each detailed index of the evaluation facility, and accordingly, as shown in FIG. 5 described above, the evaluation facility The aging level of 220 can be evaluated.

After all, according to an embodiment of the present invention, the facility is classified into the same facility by type and the same facility by classification condition, the representative facility is selected from the same facility by classification condition, and then the aging level is evaluated. Evaluation of the aging level of the evaluation facility can be easily evaluated by estimating the evaluation facility time history data by evaluating the evaluation facility without time history data, thereby reducing the aging evaluation time and evaluation cost of the evaluation facility. In addition, after collecting the time history data for the items related to old age-related detailed indicators only for representative facilities, periodically measuring the old age-related detailed indicators for representative facilities, and collecting and accumulating each data to accumulate the aging of all domestic facilities. It can be used as evaluation and basic data.
