FIG. 1 is a system configuration diagram of a radiation piping diagnostic system according to the present embodiment. As shown in FIG. 1, the radiation pipe diagnosis system according to the present embodiment includes an internal inspection device 11, a thickness measuring device 12, and a pipe sorting device 13 as pipe inspection devices. The internal inspection device 11 and the thickness measuring device 12 are used in the plant piping system 15 of the plant facility, and the internal inspection device 11, the thickness measuring device 12 and the piping sorting device 13 are buried piping systems 16 buried in the ground. Used in. In the radiation pipe diagnosis system, diagnosis is performed by managing, analyzing, and analyzing the pipes based on the radiation inspection results of the respective devices 11 to 13 for the plurality of pipes constituting the plant pipe system 15 and the buried pipe system 16. ..

The internal inspection device 11 includes an X-ray source and a radiation detector arranged so as to face each other across the pipe. As the X-ray source, a high-efficiency carbon structure type X generator tube that does not require preheating and is easy to reduce in size and weight can be used. The radiation detector detects X-rays emitted from an X-ray source, and for example, a CsI detector, a NaI detector, or the like can be used. The radiation detector measures the count value of the X-rays emitted from the X-ray source and transmitted through the pipe, and the incident X-rays are counted. This measurement is performed for each predetermined range (for example, for each pixel) on the detection surface of the radiation detector, the measurement result is processed, and the X-ray projection image of the pipe is output as inspection result data. Therefore, the detection result of the internal inspection device 11 can generate an X-ray projection image in which dents and bumps on the inner surface of the pipe appear, and the inner surface of the pipe can be inspected by the X-ray projection image.

As another example of the radiation detector, a plate coated with a brilliant phosphor capable of accumulating and recording an X-ray image may be formed on one side of an organic film. In this configuration, when X-rays are irradiated, energy is stored in the phosphor, and the phosphor emits light according to the amount of radiation absorbed. Then, after the X-ray irradiation, the plate is scanned with a laser beam to read the X-ray projected image.

In the pipe sorting device 13, the predicted value of the count value is calculated in advance for each use of the pipe, that is, in the case of a gas pipe (content is gas) and the case of a water pipe (content is water). Then, based on the comparison between this predicted value and the count value which is the measured value by the radiation detector, the use of the piping is selected and the selection result is output as detection data.

In response to the command, the analysis server 22 processes the transmitted position information so that each data and information stored in the piping information storage unit 33 associated with the latest inspection position information is extracted by the display processing unit 36. Then, each data and information extracted by the display processing unit 36 is transmitted to the terminal device 20 via the transmission unit 34, which is received by the terminal device 20 to generate an image, and is displayed on the display screen 20a. As a result, various information on radiation inspection related to piping can be obtained at the work site where the piping system is installed.

Therefore, it is possible to manage the inspection result data obtained by the inspection using radiation by each of the devices 11 to 13 in a state corresponding to the inspection position. As a result, not only can the piping state be confirmed and managed at an arbitrary position of the piping quickly and easily, but also the work and processing efficiency required for analysis and analysis of the future state can be improved.

The present invention is not limited to the above-described embodiment, and can be implemented with various modifications. Further, there are no particular restrictions on the numerical values, dimensions, materials, and directions described in the above-described embodiment. In addition, it can be appropriately changed as long as it does not deviate from the scope of the object of the present invention.

For example, the piping information storage unit 33 and the design data storage unit 35 are not limited to the configuration included as a part of the analysis server 22, and can be connected as an external hard disk or communicate with the communication network 24 by wire or wirelessly. It may be installed as a state.

Further, in FIG. 5, it is not necessary to inspect and accumulate all the inspection result data and the diagnosis result data for one inspection position information, and a part of the inspection result data may not be accumulated depending on the inspection state and the like. .. In addition, a part of each display of FIG. 3 for one inspection position information may not be displayed.

Further, the management of the piping state by the piping management unit 32 may be performed at least based on the inspection result data, and may be performed without using other data or information.

Further, the display screens 20a of FIGS. 3 to 5 are not limited to those displayed on the terminal device 20, and may be displayed on another external device. For example, in a plant such as a power plant, a display similar to the above-mentioned display screen 20a is displayed on the display of the central monitoring control device in the central control room designed so that a huge amount of information can be aggregated and all operation operations can be performed. It may be possible to manage the piping condition.
