Description

  The present invention relates to a system for remotely inspecting the appearance of nuclear fuel and equipment used for transporting nuclear fuel including transport containers.

  In particular, the present invention is an image of an inspection object intended for inspection when an external appearance of a nuclear fuel, a transport container, etc. is inspected through a video from a remote place, and the image is not replaced. The present invention relates to a remote visual inspection system for a nuclear fuel transportation device that can guarantee both that the inspection object has not been replaced and that the image has not been replaced.

  The term “nuclear fuel transport equipment” as used in this specification refers to all equipment related to transport of nuclear fuel, including nuclear fuel and transport containers for nuclear fuel.

  Regarding transportation of nuclear fuel, inspections are conducted at each stage of transportation for safety.

  Specifically, as shown in Fig. 7, shipping containers, etc. are approved at the design and manufacturing stages, and are inspected before actual shipping ("Confirmation of shipment" in Fig. 7). used.

  The transport container is used repeatedly for transporting nuclear fuel and is inspected before each transport. Appearance inspection before transport is not limited to transport containers but is also performed on nuclear fuel.

  The appearance inspection is for confirming the occurrence of large damage or deformation in the transported goods.

  Whether the object to be inspected is a nuclear fuel to be transported or a transport container is determined by confirming the individual number of the object to be inspected.

  The individual number is checked by the inspector, such as the fuel body unique number stamped on the upper tie plate in the case of fuel, and the container registration number of the plate plate welded and fixed to the outer surface of the container in the case of a transport container. This is done by visually checking the number.

  The appearance inspection is performed by visually inspecting an inspection object for damage, deformation, and the like after confirming the individual number.

  In the present invention, remote inspection (inspection object is actually placed) is replaced with on-site inspection (inspection at the place where the inspection object is actually placed) instead of the above-described conventional inspection of nuclear fuel and nuclear fuel transportation equipment. (Inspection at a place away from the place where you are).

  In the present invention, in order to inspect at a remote place, image data obtained by photographing an inspection object is transmitted to a remote place through a communication network, and a visual inspection is performed in real time on a screen of a remote computer or the like.

  A technique itself for transmitting image data to a remote location via a communication network has been known and put into practical use.

  In addition, the present invention uses a technology for projecting and displaying symbols and characters by laser light projection as will be described later.

  The technology itself for projecting and displaying symbols and characters by laser light projection is used, for example, in stage production devices.

  Further, as will be described later, the present invention uses a technique for storing and reading information in a wireless IC chip.

The technology for writing and reading the unique information by the wireless IC chip is used for, for example, a non-contact type authentication card, logistics management and the like.

  As described above, a technique for transmitting image data to a remote place and observing in real time at the remote place is conventionally known.

  However, when trying to inspect the appearance by video in a remote place, the authenticity of the video becomes a problem particularly in the field of transporting nuclear fuel, where safety is a priority.

  When visual inspection of nuclear fuel, transport containers, etc. is performed with images at remote locations, the authenticity of the images becomes a problem in two respects.

  The first problem is guaranteeing whether or not the video is real-time.

  Since the transport container is repeatedly used as shown in FIG. 7, there is a possibility that images of past appearance inspections of the same inspection object are used.

  As for nuclear fuel, the fuel assemblies are very similar in appearance, so there is a possibility that they will be replaced with images of fuel assemblies taken in the past.

  At present, image editing technology has been developed, and it has become possible to switch to another video prepared in advance in the middle of the video without being noticed by the viewer.

  For this reason, in the real-time video, the portion of the enlarged image of the inspection site is replaced with the past video of the same inspection object or video of other nuclear fuel or transportation equipment and transmitted without being noticed by the inspector. However, the possibility cannot be denied.

  As described above, when visual inspection of nuclear fuel, transport containers, etc. is performed by video at a remote place, a means for guaranteeing that the transmitted video is truly the current video is required.

  In other words, this problem can be said to prevent video / image switching.

  A second problem of authenticity of the image is a guarantee as to whether or not the inspection object is a target object.

  Nuclear fuel and shipping containers are very similar to each other with little individual difference in appearance.

  Therefore, it is conceivable that the nuclear fuel or the transport container that can pass (pass) the inspection is given a different individual number, for example, by replacing the plate, and the inspection is passed (passed). Thus, when different individual numbers are assigned to nuclear fuel or transport containers, it is difficult to confirm whether or not the nuclear fuel or transport container is the target inspection object from a remote image.

  In this way, when visual inspection of nuclear fuel, transport containers, etc. is performed with remote images, there is a need for a means to ensure that the objects displayed in the images are the true inspection objects intended for inspection. Is done.

  This problem can be said to prevent replacement of the inspection object.

  In remote visual inspection of nuclear fuel and nuclear fuel transportation equipment that place importance on safety and reliability, the above two problems must be able to be solved simultaneously.

  Therefore, the problem to be solved by the present invention is that in the remote visual inspection of nuclear fuel and nuclear fuel transportation equipment, the image transmitted to the remote location is the current image and the image displayed on the image. It is an object to provide a remote visual inspection system for nuclear fuel and nuclear fuel transportation equipment that can guarantee that the inspection object is intended for inspection.

  According to the present invention, the password data input device inputs the password data arbitrarily set by the inspector to the wireless IC chip, and the wireless IC chip is fixed to the inspection object. When the remote inspection is performed, the personal identification data authentication device reads the personal identification data from the wireless IC chip fixed to the inspection object, sends it to the remote computer, and the remote computer displays the personal identification data together with the image of the inspection object.

  According to the above flow, the password data known only to the inspector is read from the wireless IC chip of the inspection object displayed on the remote computer and displayed on the remote computer that the inspector is viewing. By displaying the password data, the inspector can confirm whether the password data is set by himself / herself.

  In this case, since the third party cannot know the password data, the third party does not know the password data even if the third party replaces the inspection object by attaching a plate with a false individual number to another inspection object. As long as the correct password data cannot be attached to the fake inspection object. Thereby, the replacement of the inspection object can be prevented, and it is possible to guarantee the identity of the inspection object, that is, the inspection object intended for inspection.

  Further, according to the present invention, when the inspector inputs an arbitrarily set symbol or character to the remote computer, the remote computer converts the symbol or character into a video signal and transmits it to the laser projection apparatus. The laser projection apparatus that has received the video signal projects a pattern or a character arbitrarily set by an inspector based on the video signal onto a predetermined place, preferably an inspection object.

  According to this system, the inspector can confirm that the symbol or character set by himself / herself has been projected on the inspection object currently being visually inspected.

  Since the third party cannot know the design and characters arbitrarily set by the inspector in real time, the third party cannot add the design or characters to a fake image and replace it with a real image.

  This ensures that the image is the current image and not a replacement image.

  Thus, according to the present invention, even when remote visual inspection is performed by a remote computer, the object displayed on the remote computer screen is the inspection object to be inspected, and the inspector It is ensured that the image of the remote computer being observed is not a replaced image, and the visual inspection of the authentic inspection object can be performed by the image at the remote location.

Then, the new password data written in the wireless IC chip is read by the password data authentication device, transmitted to the remote computer, and displayed there.

  In this case, the inspector can change the password data of the inspection object at any time, thereby confirming from the password data that the inspection object displayed on the remote computer screen is the current inspection object. be able to.

  Also, the password data displayed on the screen of the remote computer can be confirmed by the password data read by the local password data authentication device. Thereby, it is possible to prevent the password data read by the local password data authentication device from being replaced with the password data read from another wireless IC chip.

Further, the laser projection device control means 18 controls the projection position control means 17 to control the projection position of the symbols and characters by the laser light.

  The laser projection device communication means 19 inputs a video signal of a pattern and characters projected by the laser projection device 4 and a position control command for the projection position of the laser light.

  The remote computer 6 includes remote computer communication means 22, input means 23, display means 24, and information processing means 25.

  The communication network 9 preferably includes the Internet, and includes various local communication networks for connecting to the Internet.

  Next, the processing flow of the remote visual inspection system 1 will be described.

  In the remote visual inspection system 1 of the present embodiment, password data arbitrarily set by the inspector is input to the wireless IC chip 7 in order to specify an individual object to be inspected.

  The password data is input to the wireless IC chip 7 by the password data input device 8. Although the input of the password data may be performed at an arbitrary place, the wireless IC chip 7 is fixed to the inspection object 2 so as to be difficult to remove.

  At the time of remote visual inspection, an image of the inspection object 2 is photographed locally by the photographing means 10 of the image input / output device 3, and the image photographed by the photographing means 10 is converted into image data by the image data output means 11. Data is input by the image input / output device communication means 13 and transmitted to the remote computer 6. Note that “conversion” of image data by the image data output means 11 includes “compression” processing.

  First, in order to specify an individual of the inspection object 2 to be inspected, the image input / output device 3 transmits an image of the plate with the individual number assigned to the inspection object 2 to the remote computer 6. Thereby, the individual number of the inspection object 2 is displayed on the remote computer 6.

  At almost the same time, the password data is read from the wireless IC chip 7 fixed to the inspection object 2 by the wireless IC chip reader 20 of the local password data authentication device 5, and the remote data computer is read by the password data authentication device communication means 21. 6 is transmitted.

  In the remote computer 6, the remote computer communication means 22 receives the transmitted image data and password data, and the information processing means 25 causes the display means 24 to display the image and password data.

  Thereby, the inspector can confirm the personal identification data arbitrarily set corresponding to the inspection object 2 on the display unit 24 of the remote computer 6.

  In this case, since the third party cannot know the password data, even if the third party replaces the inspection object 2 by attaching a fake individual number plate to the nuclear fuel or transport container other than the inspection object, Unless the data is known, the correct password cannot be attached to the fake test object. For this reason, the replacement of the inspection object can be prevented, and it can be ensured that the inspection object is identical, that is, the inspection object is intended for inspection.

  Prior to the appearance inspection, the inspector confirms whether or not the inspection object 2 displayed on the screen is the genuine inspection object 2 to be inspected by using the password data and the image, and then the image input / output device. 3 is used to inspect the appearance of the inspection object 2.

  The appearance inspection of the inspection object 2 is performed by the inspector while remotely operating the image input / output device 3 by the remote computer 6.

  That is, the inspector gives an instruction to the position / orientation control unit 12 of the image input / output device 3 through the input unit 23 while looking at the screen to control the orientation and position of the photographing unit 10 and also to use the zoom function. A desired part of the object 2 is approached, and an image is displayed on the display means 24 (screen) of the remote computer 6 for visual inspection.

  In this case, the inspector can use the laser projection device 4 in order to confirm that the image being inspected by the inspector is not a replaced image.

  When using the laser projection device 4, the inspector inputs an arbitrary symbol or character using the input means 23 of the remote computer 6. The inputted symbol or character is converted into a video signal by the information processing means 25, and the video signal is transmitted to the local laser projection apparatus 4 by the remote computer communication means 22 according to a command from the information processing means 25.

  The transmitted video signal is received by the laser projection device communication means 19 of the laser projection device 4 and input to the laser projection device control means 18. The laser projection device control means 18 controls the laser light modulation means 15 and the scanner 16 based on the video signal, and reproduces and projects the symbols and characters arbitrarily input by the inspector. The laser light modulation means 15 can be configured using a phase diffraction grating that can electrically control the on / off control of light. The scanner 16 is driven under the control of the laser projection device control means 18 by a drive signal generated based on the video signal.

  On the other hand, the projection position of the laser light is also arbitrarily controlled by the inspector.

  The inspector inputs a projection position control command for instructing a position to project a symbol or character set by the input means 23 of the remote computer 6 while viewing the screen.
