Description

The present invention relates to a non-destructive inspection system for civil engineering structures for inspecting civil engineering structures to be inspected.

In recent years, the awareness of maintenance of existing civil engineering structures has been increasing socially, and an efficient management method is required. Inspection of such civil engineering structures is efficiently performed by using a non-destructive investigation device (see, for example, Patent Document 1).

In the inspection of civil engineering structures, there are on-site work to acquire inspection data of civil engineering structures and analysis work to analyze the acquired inspection data. Although it is efficient for analysis engineers in charge of analysis work to perform only analysis work, in order to ensure the quality of inspection data, traditionally, they go to the site where the civil engineering structure is located and directly collect the data. Have acquired. Therefore, the analysis engineer is required to perform on-site work and to and from the civil engineering structure, and the work burden is increasing. In addition, since analysis is performed after measurement and inspection data acquisition, the work becomes serial and the amount of work that can be handled is limited.

On the other hand, analysis engineers need specialized knowledge and experience, so it takes a certain amount of time for education and training, and due to the influence of the declining birthrate in recent years, it is not easy to secure personnel. ..

It is explanatory drawing which shows the nondestructive inspection system of one Embodiment of this invention.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, 10 indicates a non-destructive inspection system. The non-destructive inspection system 10 is a system for non-destructive inspection and inspection of existing civil engineering structures 11 to be inspected, such as roads, tunnels, waterways, bridges, embankments, seawalls, ports, and airports.

The non-destructive inspection system 10 includes a measuring device 13 and an analysis device 14.

The measuring device 13 is a non-contact type or contact type output unit that outputs a detection wave such as an electromagnetic wave or an ultrasonic wave, and an acquisition unit that acquires a reaction such as a reflected wave from the civil engineering structure 11 to the output from the output unit. And so on. The measuring device 13 is a device that non-destructively measures the state of the civil engineering structure 11 such as the thickness of the lining concrete in the civil engineering structure 11, the presence or absence of internal cavities G and defects, the state of reinforcing bars, and the state of internal metal objects. Is. The measuring device 13 includes, for example, buried pipes and structures of roads such as manholes M, cavities P having a risk of depression under the road surface, pavement structures S such as asphalt concrete thickness and roadbed thickness, and bridge decks. It is possible to measure F, the cavity G that causes the embankment to sink or collapse, and the like. The output unit and the acquisition unit can be realized by, for example, an antenna of a radar device. The measuring device 13 may be mounted on a measuring vehicle driven by a measuring person or a measuring assistant, such as a civil engineering structure 11 or a work vehicle capable of traveling in the vicinity thereof, or an unmanned aerial vehicle that can be remotely controlled. It may be mounted on a robot that assists in the acquisition of non-destructive inspection data of the civil engineering structure 11, such as (drone). The measuring device 13 may be singular or plural.

The analysis device 14 is a device that analyzes the non-destructive inspection data acquired by the measuring device 13. The analysis device 14 is a PC 16 which is a processing means, and a monitor 17 which is a display means capable of displaying data related to the non-destructive inspection data such as non-destructive inspection data or an image processed by the non-destructive inspection data. And so on.

Then, in the non-destructive inspection system 10 of the present embodiment, the non-destructive inspection data measured by the measuring device 13 is transmitted and stored in real time to a cloud server in a network N such as the Internet, and stored in the cloud server. The collected data is analyzed by the analysis device 14.

The measuring device 13 is lent, transferred, or sold to a person in the area where the civil engineering structure 11 is located, and the non-destructive inspection data is acquired by this person. As the personnel in the area where the civil engineering structure 11 is located, residents in the area where the civil engineering structure 11 is located or in the vicinity thereof are preferable. Therefore, it is preferable that the measuring device 13 is constructed to be fully automatic or semi-automatic, for example, so that even a person who does not have specialized skills or knowledge can use it with only simple adjustment. Further, it is preferable that the usage method such as the specific adjustment method of the measuring device 13 is prepared in advance. The manual display means for displaying the usage method may be lent, transferred, or sold together with the measuring device 13 as a printed matter or a booklet, or the measuring device 13 itself may be used as the manual display means, or on the network N. The usage method acquired from the cloud server of the above may be displayed on any display means. In the illustrated example, the measuring device 13 can be directly connected to the network N by wire or wirelessly, and can directly send and receive data to and from the cloud server on the network N, but the present invention is not limited to this. Data may be indirectly transmitted to and received from the cloud server on the network N via a communication device such as a PC or a mobile terminal that can be connected to the network N.

The analyzer 14 is used by an analysis technician who is different from the personnel who acquire the nondestructive inspection data. The analysis device 14 may be connected to the network N and may be installed in an area away from the area where the civil engineering structure 11 is located, as long as it is in a place or area where an analysis engineer performs analysis. Further, the analysis device 14 may be equipped with artificial intelligence AI. Artificial intelligence AI assists in the analysis of non-destructive inspection data for civil engineering structures 11. Specifically, the artificial intelligence AI analyzes the non-destructive inspection data (image) and detects the presence or absence of an abnormal part in the civil engineering structure 11.

Then, the non-destructive inspection system 10 of the present embodiment has a step of acquiring non-destructive inspection data of the civil engineering structure 11 from the area where the civil engineering structure 11 to be inspected is present, and non-destructive inspection data of the civil engineering structure 11. The non-destructive inspection method of the civil engineering structure 11 including the step of transmitting the image via the network N and the step of analyzing the transmitted non-destructive inspection data is carried out. Further, in the non-destructive inspection method of the civil engineering structure 11 of the present embodiment, the step of determining the repair order of the civil engineering structure 11 based on the analysis of the non-destructive inspection data and the repair order of the civil engineering structure 11 are set. Includes steps to feed back to a region.

Specifically, in the present embodiment, the measuring device 13 is lent to, for example, a locally hired person in the area where the civil engineering structure 11 is located, and the person uses the measuring device 13 to acquire non-destructive inspection data. do. At that time, by creating a manual for the on-site work, it will be possible for local personnel to easily acquire non-destructive inspection data.

The acquired non-destructive inspection data becomes a huge amount of big data. This big data is transmitted in real time to a cloud server on the network N.

The transmitted non-destructive inspection data is analyzed by a standby analysis engineer using the analysis device 14. For example, the analysis engineer processes the non-destructive inspection data displayed on the monitor 17 of the analysis device 14 or the data related to the non-destructive inspection data, and visually analyzes the data. For example, the civil engineering structure 11 Judge the presence or absence of defects, the soundness of the civil engineering structure 11 and the like. At the time of this data analysis, the artificial intelligence AI mounted on the analysis device 14 may be used.

When the analysis engineer or the artificial intelligence AI detects a defect in the civil engineering structure 11 by data analysis, the analysis engineer or the artificial intelligence AI determines the repair order of the civil engineering structure 11 or the repair order of the defect of the civil engineering structure 11. That is, the artificial intelligence AI may have the function of the artificial intelligence for determining the priority. The repair order is determined based on a predetermined standard set in advance. The input information for determining the priority is, for example, non-destructive inspection data of the civil engineering structure 11 to be inspected such as the depth, spread, and thickness of the detected cavity. In addition, the past history of inspection data, the types of civil engineering structures 11 such as bridges and roads, the amount of rain in the area where the civil engineering structures 11 are located, or the weather conditions such as temperature, and at least any of the traffic volume and vehicle types. May be used as input information for determining the priority. As an example, repairing shallow cavities is prioritized over repairing deep cavities, repairing large cavities is prioritized over repairing small cavities, and repairing thick cavities is prioritized over repairing small cavities. do. Further, the depth, the spread, and the thickness may be given a predetermined priority in advance. As an example, the depth is given the highest priority, then the spread, and the thickness is prioritized in this order. These priorities may be determined arbitrarily. The priority determination artificial intelligence does not necessarily have to be the same as the artificial intelligence AI mounted on the analysis device 14.

As the teacher data of the artificial intelligence for determining the priority, for example, the model of the input information and the judgment of the analysis engineer for the model may be used, or the repair record or the literature information may be used.

The analysis result of the data including the repair order of the civil engineering structure 11 is transmitted to, for example, a cloud server on the network N, and is fed back to the area where the civil engineering structure 11 is located.

In this way, the non-destructive inspection data acquired by the personnel in the area where the civil engineering structure 11 is located by the measuring device 13 is transmitted via the network N, and the transmitted non-destructive inspection data is analyzed by the analysis engineer. By analyzing with the analysis device 14, the analysis engineer does not have to go directly to the area where the civil engineering structure 11 is located, and the data is transferred in real time to acquire and analyze the non-destructive inspection data in parallel. The civil engineering structure 11 can be inspected efficiently, such as being able to quickly analyze the acquired non-destructive inspection data. Therefore, it is possible to reduce the cost of inspection and solve the shortage of personnel.

Further, even in the case of inspection of civil engineering structures 11 in a plurality of different areas, it is not necessary for an analysis engineer to go to acquire non-destructive inspection data each time, and it is possible to respond easily and quickly.

In particular, the areas covered by the maintenance of the civil engineering structure 11 exist in various parts of the country such as local cities, their suburbs, coastal areas, and mountainous areas. Analysis can be performed intensively in the area where the analysis device 14 is installed without going to the area, and the time and cost required for movement can be reduced. In addition, the civil engineering structure 11 can be inspected not only in Japan but also overseas.

Since the personnel who use the measuring device 13 can use the measuring device 13 by referring to the manual display means, the acquisition of non-destructive inspection data can be made more efficient, and regardless of the skill level of the personnel who use the measuring device 13, the personnel can use the measuring device 13. The accuracy of non-destructive inspection data can be ensured above a certain level. Therefore, it is not necessary for the analysis engineer himself to go to acquire non-destructive inspection data, and there is no need for night shifts or on-site work that requires physical strength, so even elderly people with specialized skills can be used as analysis engineers. It becomes possible to perform analysis.

By assisting the non-destructive inspection data of the civil engineering structure 11 with a robot or a measuring vehicle, the non-destructive inspection data can be obtained efficiently with a smaller number of people and accurately without a specialized engineer. In addition, by using a robot, it is possible to acquire data in a place that is difficult for a person to directly approach.

By mounting artificial intelligence AI on the analysis device 14 and using the detection of the presence or absence of abnormal parts by artificial intelligence AI, it is possible to suppress oversight by analysis engineers, eliminating the need for excessive expertise of analysis engineers. It is possible to suppress variations in analysis results depending on the level of the analysis engineer. In other words, by performing analysis of abnormal parts with artificial intelligence AI, it is possible to take an objective response, suppress misidentification and oversight due to human error of the analysis engineer, eliminate the need for excessive expertise of the analysis engineer, and at the same time. Time constraints due to staff shortages and education can also be suppressed. In addition, it is not necessary to check the data by a skilled analysis engineer, and the amount of work can be suppressed.

By determining the priority of the civil engineering structure 11 or the abnormal part to be repaired by the artificial intelligence AI at least based on the non-destructive inspection data, the civil engineering structure 11 or the abnormal part can be efficiently repaired without depending on the analysis engineer. .. Further, by making the artificial intelligence AI the same as the artificial intelligence AI that detects the presence or absence of an abnormal portion, a series of steps from the detection of the abnormal portion to the determination of the priority of repair can be carried out by the artificial intelligence AI.

As a result, it is possible to reduce costs, respond to diversifying work styles, and create local employment. In other words, it is possible to build a system to work without time constraints, and it will lead to new employment promotion by being able to hire experienced elderly people or people who care for children or care at home as personnel who acquire non-destructive inspection data. be able to.

The personnel who acquire non-destructive inspection data can be expected to be those who are good at geography and location information of the area where the civil engineering structure 11 is located, and it will be possible to take advantage of the strength of the network between local areas. In addition, since it is an inspection of the civil engineering structure 11 used for the life of the area where the personnel live, it also contributes to the area of the personnel.

In addition, if there is information that is judged to be an abnormal part or danger of the civil engineering structure 11 as a result of the inspection, the civil engineering structure 11 is found via the network N, including indicators such as the soundness of the civil engineering structure 11. You can promptly give feedback to the area.

For example, in the present embodiment, the repair order of the civil engineering structure 11 is determined based on the analysis of the non-destructive inspection data, and the repair order is fed back to the area where the civil engineering structure 11 is located. In recent years, the number of defects such as cavities has increased due to abnormal weather such as guerrilla rainstorms, so by feeding back the repair order of civil engineering structure 11, the priority is higher in the area where civil engineering structure 11 is located. Repairs can be carried out in order from the defect, and the civil engineering structure 11 can be repaired efficiently.
