[0048] To make the objectives, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings.

[0049] It should be noted that the terms "first", "second", etc. in the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0050] Please refer to Figures 1 to 4 As shown, the present invention provides a concrete construction maintenance management system, which includes a destructive detection unit 1, a non - destructive detection unit 2, a humidity analysis unit 3, a display unit 4, and a warning unit 5 in terms of functional modules. The destructive detection unit 1 can be a virtual functional unit as long as it can drill and sample the concrete to test the humidity, or it can also be a complete device. The non - destructive detection unit 2 uses non - destructive means to detect the non - destructive detection humidity inside the concrete component. In actual operation, there are various methods for measuring the moisture content of concrete. Two of the most common methods are using a non - destructive electronic impedance meter (ASTM F2659) or an in - situ relative humidity probe (ASTM F2170).

[0051] Before the analysis by the humidity analysis unit 3, the destructive detection unit 1 needs to execute step S01 to detect the destructive detection humidity at different position points inside the concrete component using non - destructive means. Then, the non - destructive detection unit 2 executes step S02 to detect the non - destructive detection humidity at different position points inside the concrete component using destructive means.

[0052] During the analysis by the humidity analysis unit 3, first, step S1 can be executed to perform non-destructive testing on the concrete member to obtain the non-destructive testing humidity at different position points inside the concrete member. Next, step S2 can be executed to analyze the non-destructive testing humidity at different position points of the concrete member to obtain several humidity mass regions inside the concrete member, and the humidity of the concrete within each humidity mass region is consistent. Next, step S3 can be executed to select several position points as destructive testing points within the humidity mass region. Next, step S4 can be executed to obtain the destructive testing humidity of each destructive testing point. Finally, step S5 can be executed to obtain the humidity of each position point inside the concrete member based on the destructive testing humidity of the destructive testing points corresponding to each humidity mass region.

[0053] In order to enable construction inspectors to visually observe the humidity distribution inside the concrete, the display unit 4 can execute step S041 to obtain a spatial model containing the concrete member. Next, step S042 can be executed to receive the humidity of each position point inside the concrete member. Next, step S043 can be executed to mark and display the humidity of each position point inside the concrete member within the spatial model.

[0054] In order to enable construction inspectors to promptly inspect problematic concrete areas, the warning unit 5 can execute step S051 to obtain the standard humidity range of the concrete. Next, step S052 can be executed to receive the humidity and humidity mass regions of each position point. Next, step S053 can be executed to mark the humidity mass regions containing position points with humidity not within the standard humidity range of the concrete as warning humidity mass regions. Finally, step S054 can be executed to give a warning for the warning humidity mass regions.

[0055] Please refer to Figure 5 As shown, since the concrete may be non-uniform during construction mixing and subsequent solidification, in order to reduce the damage to the concrete member caused by destructive testing, the concrete member can first be divided into humidity mass regions with similar internal humidity through non-destructive testing. Specifically, first, step S21 can be executed to uniformly select multiple position points as positioning points among the position points of the concrete member. Next, step S22 can be executed to obtain the difference between the maximum value and the minimum value of the non-destructive testing humidity of each positioning point. Next, step S23 can be executed to use the ratio of the difference between the maximum value and the minimum value of the non-destructive testing humidity of each positioning point to the total number of positioning points as the division gradient value. Finally, step S24 can be executed to take the region occupied by multiple adjacent positioning points with a difference in non-destructive testing humidity less than the division gradient value among the positioning points of the concrete member as the humidity mass region.

[0056] Please refer to Figure 6As shown, since the humidity mass regions may be large and cannot all be used as sampling points for destructive testing as a whole, it is necessary to select the most representative positioning points as the destructive testing points. Specifically, first, step S31 can be executed to classify the humidity mass regions according to the shape and area of each humidity mass region to obtain grouped mass regions. Next, step S32 can be executed to select one humidity mass region from each grouped mass region as the representative humidity mass region. In actual operation, within each grouped mass region, the humidity mass region corresponding to the representative region feature vector in subsequent step S313 can be used as the representative humidity mass region. Next, step S33 can be executed to obtain the geometric center of each representative humidity mass region. Finally, step S34 can be executed to obtain the positioning point closest to the geometric center in each representative humidity mass region as the destructive testing point.

[0057] Please refer to Figure 7 As shown, since the number of divided humidity mass regions may be large, if all are subjected to destructive humidity testing, it may cause excessive damage to the concrete components. Therefore, only one humidity mass region with similar or the same state needs to be tested, which requires grouping the humidity mass regions according to their characteristics. Specifically, first, step S311 can be executed to calculate and obtain the ratio of the area of each humidity mass region to the area of its minimum circumscribed rectangle as the shape factor of each humidity mass region. Next, step S312 can be executed to use the two-dimensional vector composed of the shape factor and area values of each humidity mass region as the region feature vector of the humidity mass region. Next, step S313 can be executed to select several from all the region feature vectors as the representative region feature vectors. Next, step S314 can be executed to calculate and obtain the vector difference norm between each representative region feature vector and other region feature vectors. Next, step S315 can be executed to classify each other region feature vector and the representative region feature vector with the smallest vector difference norm into the same grouped mass region.

[0058] Since the region feature vectors within the grouped mass region may not have sufficient consistency at this time, next, step S316 can be executed to calculate and obtain the region feature vector with the smallest vector difference norm from the mean vector within each grouped mass region as the updated representative region feature vector. Next, step S317 can be executed to determine whether the updated representative region feature vector has changed. If so, it means that all the region feature vectors within the grouped mass region have consistency at this time. Therefore, next, steps S314 to S317 can be continuously executed to update the grouped mass regions and the representative region feature vectors. If not, it means that all the region feature vectors within the grouped mass region do not have consistency at this time. Therefore, finally, step S318 can be executed to obtain the classified grouped mass regions.

[0059] To supplement the implementation process of the above steps S311 to S318, the source code of some functional modules is provided, and corresponding explanations are given in the annotation part. To avoid the leakage of data involving business secrets, some data that does not affect the implementation of the solution is desensitized. The same applies hereinafter.

[0065] This code first defines a Cluster structure for representing the area of a humidity blob, which includes the shape factor and the area. Then, the shape factor is obtained by calculating the ratio of the area of the minimum bounding rectangle of each blob to the area of the blob itself, and the shape factor and the area are combined into a two-dimensional feature vector. Next, all blobs are processed, grouped according to the shape factor and the area, and finally the group to which each blob belongs is output. This method can effectively classify the blob areas according to the shape and area features.

[0066] Please refer to Figure 8 As shown, since the non-destructive detection humidity of each positioning point within the same humidity blob area is not exactly the same, and there may be systematic deviations in the detected values of the non-destructive detection humidity, it is necessary to correct it. Specifically, within each humidity blob area, first, step S51 can be executed to calculate the ratio of the destructive detection humidity of the destructive detection point to the corresponding non-destructive detection humidity as the correction coefficient. Next, step S52 can be executed to obtain the corrected non-destructive detection humidity of each positioning point as the humidity of the positioning point according to the non-destructive detection humidity of each positioning point and the correction coefficient. Next, step S53 can be executed to smooth the humidity of each positioning point within the humidity blob area to obtain the humidity of each position point within the humidity blob area. Finally, step S54 can be executed to summarize the humidity of each position point within each humidity blob area to obtain the humidity of each position point inside the concrete member.

[0067] To supplement the implementation process of the above steps S51 to S54, the source code of some functional modules is provided, and corresponding explanations are given in the annotation part. To avoid the leakage of data involving business secrets, some data that does not affect the implementation of the solution is desensitized. The same applies hereinafter.

[0071] This program first defines the structures Point and Cluster to represent a single location point and a humidity mass region respectively. Each mass contains multiple location points and a damage detection point. The program first calculates the ratio of the humidity between the damage detection point and a non-damage detection point as a correction factor. Then this correction factor is used to adjust the humidity values of all points in the mass. After that, the humidity data within the mass is smoothed to reduce the impact of anomalies at individual measurement points on the whole. Finally, through correction and smoothing, this method provides a more accurate and balanced way to estimate the humidity at each location point inside the concrete member.
