As shown in FIG. 1 , the plant management apparatus 1 includes an input section 12 , an infrared camera 14 (imaging device), a control section 20 , a storage section 30 and a display section 40 .

The input unit 12 inputs various data (for example, design information and measurement information regarding the plant equipment P).

The infrared camera 14 captures infrared rays radiated from the plant equipment P and its background. The infrared camera 14 may be installed at a predetermined location in the plant facility P (installation type), may be arranged so as to be transportable (portable type), or may be mounted on a small unmanned aircraft (drone type). , may be mounted on a robot that automatically patrols the inside of the plant facility P (patrol photographing robot type).

The storage unit 30 stores the infrared image and additional information about the shooting location and shooting direction of the infrared camera 14 that accompanies the infrared image.

The visible light camera 16 captures visible light reflected from the plant equipment P. The acquisition unit 24 acquires the shooting location and shooting direction of the visible light camera 16 . The visible light camera 16 may be installed at a predetermined location in the plant facility P (installation type), may be arranged so as to be transportable (portable type), or may be mounted on a small unmanned aircraft (drone type). ), it may be mounted on a robot that automatically patrols the inside of the plant facility P (patrol photographing robot type).

The visible light camera 16 periodically transmits the captured visible light image of the plant equipment P to the control unit 20 . The storage unit 30 stores a visible image and additional information about the shooting location and shooting direction of the visible light camera 16 that accompanies the visible image. It is preferable that the visible light camera 16 shoots in the same shooting direction from the same shooting point as the infrared camera 14 . The visible light camera 16 and the infrared camera 14 may be configured integrally.

The control unit 20 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The CPU reads a program corresponding to the processing content from the ROM, expands it in the RAM, and centrally controls the operation of each block of the plant management apparatus 1 in cooperation with the expanded program. At this time, various data stored in the storage unit 30 are referenced. The storage unit 30 is configured by, for example, a nonvolatile semiconductor memory (so-called flash memory) or a hard disk drive.

The control unit 20 communicates variously with a device (for example, an infrared camera 14, a visible light camera 16) connected to a communication network such as a LAN (Local Area Network) or a WAN (Wide rea Network) via a communication unit. Send and receive data. The control unit 20 implements the functions of the generation unit 22, the acquisition unit 24, the alignment unit 26, and the image generation unit 28, for example, based on various data transmitted from an external device.

The generation unit 22 generates a three-dimensional model in a virtual space on the computer based on various data input by the input unit 12 . Here, the various data include the layout of the plant equipment P as a whole (including position coordinates), the positions and shapes of the component parts that make up the plant equipment P, information on the refined product in the plant equipment P (for example, in the case of gas, type, flow rate in piping, pressure, temperature, etc.), design information of plant equipment P, measurement data of plant equipment P (environmental data such as temperature, humidity, sunshine conditions, wind speed, atmospheric pressure, etc.).

The acquisition unit 24 acquires information (status information) about the status of the plant equipment P as a status image. For example, when the information about the status of the plant equipment P is temperature information or fluid leakage information, the acquisition unit 24 acquires an infrared image (status image) of the plant equipment P photographed by the infrared camera 14 . The acquisition unit 24 also acquires the shooting location and shooting direction of the infrared camera 14 .

The acquisition unit 24 also acquires the shooting location and shooting direction of the visible light camera 16 .

The image processing/analysis unit 25 extracts an image (extracted image) and a temperature image of the gas leakage area by image-processing the infrared image captured by the infrared camera 14 . In addition, the image processing/analysis unit 25 performs image processing and image analysis on the visible light image captured by the visible light camera 16 to obtain an image (extracted image) of the rust area showing the state of rust generation in the plant equipment P, An image (extracted image) of the deformation area indicating the deformation state of the external shape of the plant equipment P or an image (extracted image) of the vibration area indicating the vibration state of the plant equipment P is extracted. In the following description, the situation image includes an image (extracted image) of the gas leakage area and a temperature image extracted from the infrared image (original image) by image processing. The situation image includes an image of the rust area (extracted image), an image of the deformed area (extracted image), or a vibration image of the plant equipment P (extracted image) extracted from the visible light image (original image). be

Further, the image processing/analysis unit 25 obtains spatial coordinate information of the gas cloud spreading in space and information (situation information) of the gas leak position from the image of the gas leak area. A known method such as the method described in Japanese Patent No. 6620878 can be used as a method for estimating the leak position.

The image processing/analysis unit 25 obtains temperature information (status information) of the components by converting the value of each pixel of the captured infrared image (situation image) based on a predetermined formula.

The image processing/analysis unit 25 obtains vibration information (amplitude and frequency) of component parts such as piping that constitutes the plant equipment by analyzing the captured visible light image (situation image). A technique for obtaining vibration information is described in, for example, International Publication WO2018207528.

The image processing/analysis unit 25 obtains rust information (status information) regarding the appearance of component parts such as piping that constitutes the plant equipment by analyzing the captured visible light image (status image). The occurrence of rust can be recognized by using color information of the image, for example.

The image processing/analysis unit 25 obtains deformation information (situation information) regarding the appearance of component parts such as piping that constitutes the plant equipment by analyzing the captured visible light image (situation image). Occurrence of deformation can be obtained by comparing the photographed image and the design information of the plant facility P, for example. Alternatively, it can be obtained by using a camera capable of acquiring three-dimensional information of an object to be photographed and comparing the obtained three-dimensional shape of the object to be photographed with the design information of the plant equipment P. Three-dimensional information can be obtained using, for example, a distance measurement method based on triangulation or a distance measurement method using the speed of light.

The alignment unit 26 associates the position of each pixel of multiple types of situation images (gas leak area image, rust area image, etc.) with the coordinate position of the three-dimensional model. In the following description, associating the situation image with the three-dimensional model means associating the position of each pixel of the situation image with the position in the coordinates of the three-dimensional model.

The storage unit 30 stores information (status information) about the status of the plant equipment P in association with the corresponding part of the three-dimensional model. Specifically, the storage unit 30 stores an infrared image of the plant equipment P captured by the infrared camera 14 in association with the three-dimensional model. The storage unit 30 also stores the visible light image of the plant equipment P captured by the visible light camera 16 in association with the three-dimensional model.

FIG. 3 is a diagram showing an example of situation information stored in association with position coordinates of a three-dimensional model. As shown in FIG. 3, the storage unit 30 stores the shooting date and time as supplementary information. The storage unit 30 also stores the surface temperature (° C.), the presence or absence of gas leakage, and the presence or absence of rust as status information. As shown in FIG. 3, "20", "40", and "25" in the column of surface temperature indicate the surface temperature ° C., "0" in the column of gas leakage indicates that there is no gas leakage, and "1 ” indicates that there is a gas leak. In addition, the extent (spatial coordinates) of the gas cloud in the three-dimensional space is stored in association with the gas leak position (not shown). The spatial coordinates of the gas cloud can be calculated from infrared images taken from multiple locations. If there is only an infrared image from one direction, the calculation may be performed by assuming that the spread in the depth direction is the same as the spread in the horizontal direction. In addition, captured infrared images (including moving images) or gas cloud images (including moving images) extracted by image processing may be stored in association with gas leak positions. A "0" in the rust column indicates no rust and a "1" indicates rust present. It may be stored in multiple stages according to the state of rust.

The image generator 28 generates an image of the plant equipment P (hereinafter referred to as a plant image) from a predetermined viewpoint based on the three-dimensional model.

The display unit 40 displays the information of each pixel of the situation image by superimposing it on the corresponding position on the plant image.

FIG. 4 is a diagram showing an example of displaying the information of each pixel of the situation image superimposed on the corresponding position on the plant image. In one example shown in FIG. 4, the plant image is an image of a gas tank. The situation image is an image (here, gas cloud) showing the state of gas leakage. As for the gas cloud, a CG (Computer Graphics) image generated based on the spatial coordinates of the gas cloud stored in the storage unit 30 is displayed. A map (a plan view of a 3D model) of the plant facility P is displayed at the bottom of the display screen. The viewpoint position of the infrared camera 14 is indicated in the plan view of the 3D model as a black circle. A height bar specifying the height of the viewpoint is displayed on the right side of the plan view of the 3D model. In the plan view, the field angle range of the plant image from the viewpoint (black circle) is indicated by a dashed line. A diagram of a combination of ellipses indicating the orientation of the viewpoint is displayed in the lower right portion of the display screen. The direction of the viewpoint and the display angle of view can be changed by operating the mouse on the plant image. Alternatively, it may be made changeable by moving a black circle and a height bar in the plan view. The display angle of view may be changed by + and - buttons.

Each component of the control unit 20 may be connected via a network, and the three-dimensional model may be stored on the cloud, for example. Also, the control unit 20 may be on the cloud. The control unit 20 may be composed of a plurality of CPUs and may operate integrally by being connected via a network. The storage unit 30 may also be configured in a distributed manner. Moreover, the display unit 40 may be arranged in the plant facility P. Further, the display unit 40 may be arranged in a central monitoring room or the like of the head office to centrally manage the plant facilities P in various places.

Next, an example of the plant management method according to the embodiment of the present invention will be explained. FIG. 5 is a flow chart showing an example of the plant management method according to the embodiment of the invention. This flow starts when the CPU develops the plant management program in the RAM. It is assumed that the control unit 20 executes each function of the generation unit 22, the acquisition unit 24, the image processing/analysis unit 25, the alignment unit 26, and the like.

First, as an example of the plant management method, the steps from the start of this flow to the storage of the status information will be described with reference to FIG. Here, an image (situation image) of a gas leakage area will be described as an example of situation information.

In step S100, the control unit 20 generates a three-dimensional model of the plant equipment P in the virtual space on the computer based on at least one of the design information and the measurement information regarding the plant equipment P. The design information includes the three-dimensional shape and position information of the plant equipment P. The measurement information includes the three-dimensional shape and position information of the plant equipment P measured by a three-dimensional measuring device using a laser or the like.

Next, in step S110, the controller 20 acquires an infrared image.

Next, in step S120, the control unit 20 extracts an image (extracted image) of the gas leakage area from the infrared image by image processing. Further, the control unit 20 estimates the leak position from the image of the gas leak area.

Next, in step S130, the control unit 20 associates the image of the gas leak area and the leak position with the three-dimensional model.

As for the method of associating the image of the gas leak area with the three-dimensional model, for example, the photographing point of the infrared camera 14 is acquired by a GPS (Global Positioning System), an altitude sensor, or the like. The photographing direction of the infrared camera 14 is acquired by an acceleration sensor, a gyro sensor (angular velocity sensor), a geomagnetic sensor, or the like. The acquired shooting point and shooting direction are applied to the 3D model of the plant facility P, and based on the angle of view information (focal length and image sensor size information) of the camera, the plant image generated from the 3D model is converted to the camera. By cutting out the field angle range, a plant image having the same viewpoint and the same field angle as the photographed image is obtained. Alternatively, the equipment in the photographed image may be recognized from the information of the photographing location and the shape information of the plant equipment P, for example, by pattern recognition. As a result, each pixel of the situation image (captured image) and the three-dimensional model of the plant equipment P can be associated with each other. Furthermore, information for each pixel extracted from the situation image (information possessed by the pixel of the situation image) can be incorporated into the three-dimensional model as information about the situation of the plant facility P at the position corresponding to the pixel.

Next, in step S140, the storage unit 30 stores the image of the gas leak area and the leak position in association with the corresponding part of the three-dimensional model. After that, the flow shown in FIG. 5 ends.

Next, the steps up to displaying the situation information (here, information on the gas leakage area) on the plant image will be described with reference to FIG. FIG. 6 is a flow chart showing another example of the plant management method according to the embodiment of the invention. This flow starts when the CPU develops the plant management program in the RAM. Note that the control section 20 will be described as executing the functions of the image generating section 28 and the like.

In step S200, the control unit 20 determines whether or not a viewpoint for creating a three-dimensional model has been designated.

In step S<b>210 , the control unit 20 reads the three-dimensional model data from the storage unit 30 , generates a plant image from the specified viewpoint, and causes the display unit 40 to display the image.

At step 220, the control unit 20 determines whether or not any of the status information (surface temperature, gas leakage, presence or absence of rust, vibration, etc.) to be superimposed on the plant image has been specified.

In step S230, based on the specified situation information (here, gas leakage), the control unit 20 blinks the leak position (red target mark) at the corresponding position on the plant image, and also displays the gas cloud on the plant image. CG is displayed at the position corresponding to . After that, the flow shown in FIG. 6 ends. In addition, you may return to before step S200 after that.

FIG. 7 is a diagram showing another example of situation information displayed superimposed on the corresponding position on the image of the plant image P (plant image) from the viewpoint. As shown in FIG. 7, a plant image from a viewpoint is displayed, and situation information (here, temperature distribution) is superimposed on the corresponding position of the plant image. In FIG. 7, the difference in temperature is represented by the type of hatching. The amount of liquid stored can be recognized from the temperature information (indicated by the black area in FIG. 7). The display screen also displays switching buttons for displaying information on temperature, vibration, rust, and gas leakage. By specifying the information to be displayed, the information can be superimposed on the plant image and displayed. When "Temperature" is specified, the measured temperature is displayed in multiple colors, from low temperature: purple to high temperature: red. When "vibration" is specified, for example, an area where the vibration exceeds a predetermined value is displayed blinking. It may be displayed in multiple colors according to the amplitude of vibration. If "rust" is specified, for example, the area with rust is displayed blinking in red. It may be displayed in multiple colors according to the degree of rust. When "gas leakage" is specified, the location of the leakage is indicated by, for example, a red target mark and blinking. A plurality of pieces of information may be displayed on the plant image. By specifying multiple switching buttons, the specified information is displayed at the same time.

The plant management method according to the present embodiment includes a three-dimensional model generation step of generating a three-dimensional model of the plant equipment in a virtual space on a computer based on design information related to the plant equipment in the real space, and A situation image acquisition step of acquiring information as image information, and a storage step of storing the information relating to the situation of the plant equipment acquired as image information in association with the corresponding portion of the three-dimensional model.

With the above configuration, since information (status information) about the status of the plant equipment P is obtained as a status image, a large number of status images can be obtained at a low cost compared to the case of arranging a large number of sensors for detecting information about the status of the plant equipment P. can be obtained. This makes it possible to suppress an increase in cost. In addition, it becomes possible to import a large amount of situation information as data into the three-dimensional model of the plant at one time, so that the accuracy of various simulations such as operation simulation and deterioration simulation of the plant equipment P can be improved.

In addition, the plant management method according to the present embodiment captures the plant equipment P using a plurality of infrared cameras 14 arranged at mutually different positions, a patrolling photographing robot, or a drone, so that the plant equipment can be viewed from many viewpoints. Acquire an infrared image of P. Since infrared images are obtained from a plurality of viewpoints, information regarding the plant equipment P can be obtained from various directions. Therefore, information about the plant equipment P can be obtained without omission. In addition, when a gas leak is photographed, the position of the gas leak in a three-dimensional space and the spread of the gas cloud can be calculated from the images from multiple viewpoints, so the gas leak area of the plant equipment P can be captured three-dimensionally. becomes possible.

In addition, the plant management method according to the present embodiment inputs information obtained from many infrared images (for example, temperature information, gas leak information) and information from visible images (information on rust and vibration) into the 3D model. can be used to simulate plant conditions, so the accuracy of the simulation can be easily improved.

First, Modification 1 of the present embodiment will be described with reference to FIG.

As shown in FIG. 8, the plant management apparatus 1 according to Modification 1 includes a transmissive spectacles-type terminal 50 (hereinafter referred to as smart glasses) through which the view of the plant equipment is transmitted. The smart glasses 50 transmit and receive data to and from the control unit 20 via a communication line such as a LAN (Local Area Network) or the Internet line. Note that FIG. 8 omits the transmission/reception units provided in each of the control unit 20 and the smart glasses 50 .

As a result, for example, hydrocarbon gases that transmit visible light, which cannot be seen with the naked eye, can be visualized through the smart glasses 50, making it possible to instantly and accurately visually recognize gases that are at risk of explosion.

Note that in the plant management device 1 according to Modification 1, the smart glasses 50 may have each function of the control unit 20 .

(Modification 2)
Next, the plant management device 1 according to Modification 2 will be described with reference to FIG. FIG. 9 is a diagram schematically showing the configuration of a plant management device according to Modification 1 of the present embodiment. In addition, in the description of Modification 2, the configuration different from that of the above-described embodiment will be mainly described, and the same configuration will be given the same reference numerals, and the description thereof will be omitted.

A plant management apparatus 1 according to Modification 2 includes a simulation execution unit 66 and a maintenance information creation unit 68 in addition to the configuration of the above embodiment.

The simulation execution unit 66 simulates the deterioration of the plant equipment P based on the three-dimensional model, the history of the situation images and the situation information continuously stored in the storage unit 30 . Here, the deterioration of the plant equipment P refers to the deterioration of the plant equipment P and the constituent parts of the plant equipment P, and includes, for example, metal fatigue, damage, rust, spread of deformation, failure risk, and the like.

The storage unit 30 stores maintenance information in association with the three-dimensional model.

FIG. 10 is a diagram showing an example of maintenance information stored in association with a three-dimensional model. As shown in FIG. 10, the history of maintenance information is stored in the storage unit 30, such as when maintenance was performed on a particular component (for example, the pipe 1) and the details of the maintenance. In addition, schedules of maintenance information such as the timing of the next maintenance based on a simulation or the like and the details of the maintenance are stored. As shown in FIG. 10, the pipe 1 was replaced on March 5, 2018 and March 10, 2019, and the replacement schedule for April 2020 is stored.

The display unit 40 displays the maintenance information superimposed on the image of the three-dimensional model. Specifically, as shown in FIG. 2, the display unit 40 displays the maintenance information of "inspection time 20xx year xx month" superimposed on the image of the three-dimensional model.

The plant management apparatus 1 according to Modification 2 includes a simulation execution unit 66 that simulates the deterioration of the plant equipment P based on the three-dimensional model, continuously stored situation images, and the history of the situation information. The simulation execution unit 66 uses the temperature information, vibration information, rust information, deformation information and change history information stored in the storage unit 30, and measurement information from various sensors arranged in the planton facility P. From this, for example, the degree of metal fatigue is simulated, and the future situation is predicted from the situation of that change. For example, with temperature information, the degree of deterioration is determined in consideration of the location of abnormal temperature occurrence, the number of abnormal temperature occurrences, the amplitude of the temperature change cycle, and the number of times. For example, in the vibration information, the abnormal state and the degree of deterioration are determined from the location of vibration occurrence, the amplitude of vibration, and the frequency of vibration. Further, the degree of deterioration is determined from the state of rust and deformation of pipes, for example. In addition to this information from the appearance, for example, design information and measurement information such as the flow rate and pressure of the fluid flowing through the pipe, the material and thickness of the pipe, etc., can be taken into account to estimate the progress of deterioration of the pipe. The surface condition of the plant equipment P is acquired based on the situation image, and the information contained in the situation image is used to simulate the deterioration of the plant equipment. It is possible to obtain simulation results precisely.
