Description

  The present invention relates to a progress management terminal, a progress management system, a progress management method, and a progress management program.

  In construction sites such as chemical plants, plant construction and maintenance systems that allow workers to carry mobile terminals have been proposed. On the display screen of the portable terminal, information for supporting the worker's plant construction and maintenance work is displayed. Thus, the worker can easily grasp the work contents at the work site without reciprocating between the office that receives the work instruction and the work site that executes the work instruction.

  In Patent Document 1, position / direction data viewed by an operator is detected by a gyro compass, a 3D image that the operator should be viewing is calculated from the detection result, and necessary information is added to the 3D image. A plant maintenance support system to be shown to the worker is described. Thereby, the 3D image (virtual space) of the construction system created by 3D-CAD (Computer Aided Design) can be linked to the real space and can be grasped by the worker.

  Patent Document 2 describes an inspection system that enables an evidence photograph taken by an inspector on site to be easily input in association with an imaging point to be inspected. This automatically associates from which position the evidence photograph was taken and in which direction, so that it is possible to reduce the trouble of inputting the photographing point.

JP 2008-269310 A Japanese Patent Application Laid-Open No. 2011-8864

  When the plant is under construction, the 3D image (virtual space) displayed on the worker's mobile terminal may be significantly different from the space (real space) in the field that the worker is actually viewing. . In the initial state of construction, since construction materials are gradually transported to the construction site and assembled, the construction materials are sparsely present in the real space and are not assembled. On the other hand, since the virtual space uses the data of the completed drawing of the plant created in advance by the construction office, all the construction materials are arranged and the materials are assembled accurately.

  Therefore, the worker at the site of the plant under construction cannot obtain sufficient information for supporting the work at the site even when viewing the display screen of the mobile terminal because the real space and the virtual space are visually different. . Therefore, a plant system that supports field work in the plant under construction is desired.

  Therefore, a main object of the present invention is to provide a system that supports plant construction and maintenance work in a plant under construction.

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

  FIG. 1 is an explanatory diagram showing an overview of the progress management system. The progress management system supports progress management related to construction such as confirmation of equipment installation status, equipment performance tests and inspections at construction sites such as chemical plants.

  Fig.1 (a) shows the real space of the plant which is the object of progress management. Note that the term “real space” refers to the tablet 1 (progress management terminal) possessed by the worker 101 (in this case, not only the person who actually performs the construction work but also the general user including the work supervisor). ) Is used for comparison with the “virtual space” which is the display screen. The worker 101 is present in front of the eyes by comparing the shape data of an object such as a tank in the virtual space displayed on the tablet 1 with the shape of the construction target 102 in the real space in front of the eyes. It is possible to easily identify the object to be operated. The shape data of the object is stereoscopic data used in 3D-CAD or the like, and is registered in advance in the integrated database 2a in FIG.

  Further, the inspection data input by the worker 101 is stored in the tablet 1 by associating the inspection data with the identified object (ID) so as not to cause an object selection error by the worker 101. it can. The inspection data for each object includes, for example, progress data in the object construction process, photograph data obtained by photographing the object, and inspection form data describing inspection items for the object.

  FIG. 1B is a configuration diagram of the progress management system. In the progress management system, the integrated server 2 (progress management server) installed on the construction office side and the tablet 1 possessed for each worker 101 at the construction site are connected by communication means such as a wireless LAN (Local Area Network). It is connected. The integrated server 2 collects the inspection data input from each tablet 1 and manages it in the integrated database 2a. Thereby, input data by a certain worker 101 can be referred to by another worker 101 via the integration server 2.

FIG. 2 is a configuration diagram illustrating a tablet of the progress management system. The tablet 1 includes a basic configuration unit 10, an interface unit 20, and a position processing unit 30.
The basic configuration unit 10 communicates with a CPU (Central Processing Unit) 11 as a control means, a RAM (Random Access Memory) 12 as a storage means, a ROM (Read Only Memory) 13 and other devices as a basic configuration of the computer. It is comprised from the communication part 14 which is an interface for doing.

The interface unit 20 is configured to be operated by the worker 101, and includes a touch panel 21, a display control unit 22 that controls display contents on the touch panel 21, an input control unit 23 that controls input contents from the touch panel 21, and a touch panel. And a camera 24 installed on the same surface (front surface) as 21 or on the opposite surface (rear surface).
The position processing unit 30 includes a GPS (Global Positioning System) 31 and a three-axis acceleration sensor (gyro sensor 32) as sensors for determining the position of the tablet 1 in the real space and the position of the virtual camera in the virtual space. And at least one of the geomagnetic sensor 33 and the atmospheric pressure sensor 34.

  Hereinafter, the space position (latitude, longitude, altitude) of the real space for the worker 101 (tablet 1) is (X, Y, Z), and the direction (pitch, yaw) of the camera 24 centered on the space position of the real space. , Roll) is (A, B, C). Similarly, the spatial position of the virtual space is (x, y, z), and the orientation of the camera 24 around the spatial position of the virtual space is (a, b, c).

  The measured value of the GPS 31 is used to obtain (X, Y, Z) which is the position of the tablet 1. The GPS 31 may use radio waves from a satellite as a clue for obtaining (X, Y, Z), or D (Differential) -GPS or RTK (Real Time Kinematic) -GPS. The position (X, Y, Z) may be corrected by radio waves from an electronic reference point previously arranged around the tablet 1.

  Further, Z (elevation) of the position of the tablet 1 can be corrected or replaced by the atmospheric pressure value obtained by the atmospheric pressure sensor 34. If the GPS 31 is used alone, the measurement radio wave is weakened by the surrounding shielding object, and the position measurement accuracy is lowered. However, by using the atmospheric pressure sensor 34, it is possible to obtain a highly accurate Z (elevation) without being affected by surrounding shielding.

The measured value of the gyro sensor 32 is used to obtain (A, B, C) which is the direction of the camera 24. The (A, B, C) can be corrected by the measured value of the geomagnetic sensor 33.
Then, the CPU 11 mutually converts the spatial position (X, Y, Z) of the camera 24 in the real space and the spatial position (x, y, z) of the virtual camera in the virtual space. The direction (A, B, C) and the direction (a, b, c) of the virtual camera are mutually converted.

Tablet 1
A progress management terminal possessed by the worker at the construction site in the real space;
A virtual space in which the space position of the real space is associated is prepared, and for each object arranged in the real space, the ID of the object, the progress status of the work of the object, the solid shape of the object in the virtual space, and A RAM 12 for storing the virtual positions to be arranged in association with each other;
A position processing unit 30 that measures a real position, which is a spatial position in the real space of the worker himself,
A virtual position of the virtual camera 24 for displaying a three-dimensional shape in the virtual space stored in the RAM 12 is obtained from the actual position measured by the position processing unit 30, and the virtual camera 24 is viewed from the viewpoint of the obtained virtual camera 24. An interface unit 20 that performs processing for displaying an object on a display unit in a display form that differs for each progress state, and processing for receiving selection of an object to be displayed;
When receiving input of inspection data for the object selected by the interface unit 20, the CPU 11 stores the input inspection data and the ID of the object selected by the interface unit 20 in association with each other in the RAM 12. .

FIG. 3 is a flowchart showing processing of the progress management system.
As S101, the integrated server 2 transmits the contents of the integrated database 2a registered in advance to the tablet 1. As described above, in the integrated database 2a, the three-dimensional shape of the construction object 102 (object), the position information where the three-dimensional shape is arranged, the inspection data (data registered by other tablets 1), and Are registered in association with the object ID.
As S <b> 102, the tablet 1 receives the contents of the integrated database 2 a of S <b> 101 via the communication unit 14 and reflects the received contents in the virtual space data of its own RAM 12. By this reflection process, the tablet 1 can display the three-dimensional shape of the construction object 102 on the touch panel 21 in the subsequent processes.

As S111, the tablet 1 determines whether or not it is an opportunity to detect the spatial position (x, y, z) and orientation (a, b, c) of the virtual camera.
As S112, the position processing unit 30 detects the position (X, Y, Z) of the user (tablet 1) in the real space and the direction (A, B, C) of the camera 24.
As S113, the CPU 11 converts the spatial position (X, Y, Z) of the camera 24 in the real space obtained in S112 into the spatial position (x, y, z) of the virtual camera in the virtual space, and , By converting the orientation (A, B, C) of the camera 24 obtained in S112 into the orientation (a, b, c) of the virtual camera, the viewpoint of the virtual camera in the virtual space (combination of position and orientation) ).

  Note that the above-described S111 to S113 have shown a method of linking the viewpoint of the real space directly with the viewpoint of the virtual space as an example of the viewpoint update processing of the virtual camera. On the other hand, the viewpoint of the virtual camera in the virtual space may be updated directly by the worker 101 via the touch panel 21 regardless of the viewpoint of the real space.

  For example, the worker 101 moves the position of the virtual camera by dragging the touch panel 21 up, down, left and right with one finger, and pinches with two fingers to zoom the virtual camera. The virtual camera is rotated by rotating the finger while touching with two fingers. When receiving an operation on these touch panels 21, the input control unit 23 updates the viewpoint of the virtual camera in accordance with the operation. The input control unit 23 may accept an operation on the touch panel 21 using an operation unit such as a stylus pen instead of a finger.

  On the other hand, the worker 101 inputs specific information (search conditions such as ID and name) of an object to be noted (full screen display) to the touch panel 21 and causes the CPU 11 to search the data in the integrated database 2a. Good. The CPU 11 may acquire the data of the object that matches the search condition from the data of the integrated database 2a, and update the viewpoint of the virtual camera so that the spatial position associated with the data of the object is easy to see.

As S114, the input control unit 23 accepts selection of a target object in the virtual space in which the viewpoint of the virtual camera updated in S113 is projected by a touch operation or the like.
As S121, the input control unit 23 receives input of inspection data for the target object selected in S114. As a result, it is expected that the number of man-hours on site will be greatly reduced compared to the inspection work (inspection / photographing / progress input) performed using paper-based plan drawings.

Note that the inspection data input in S121 is a photograph of the tank or input data to the tank form if the target object is a tank in the progress state “installing”. Furthermore, when the installation work is completed, the input control unit 23 receives, as inspection data, an input indicating that the progress state “Installing” is changed to the next state “Temporary welding”.
The CPU 11 associates the object ID of the target object selected in S114 with each inspection data input in S121. Then, the communication unit 14 transmits the associated inspection data to the integrated server 2.

  As S122, the integrated server 2 receives the data of the target object of S121 and writes the received data to the integrated database 2a. Here, since each inspection data is associated with the object ID in the data of S121, each inspection data is stored in a state associated with the object ID also in the integrated database 2a. Thereby, since design information (object ID) and construction information (each inspection data) are linked, these data can be managed collectively.

  Furthermore, each inspection data of the worker 101 belonging to the A department written out in S122 is also transmitted to the tablet 1 of the worker 101 belonging to the B department in S101. As a result, the construction status of the plant can be shared and managed seamlessly across multiple departments such as the field department and the design department. In this way, various information from each site is sucked up from the tablet 1 to the integrated server 2 and shared, leading to an improvement in the speed of decision making between departments. In particular, there is a high possibility of early detection when, for example, unintended construction on the design side has been performed, and the return work can be reduced. In addition, since it is not necessary for the operator of the integrated server 2 to re-input each inspection data input to the tablet 1, the burden on the operator in the office can be reduced.

  In S123, the integrated server 2 creates various reports from the contents of the integrated database 2a written in S122. The process of creating various reports will be described later with reference to FIG.

FIG. 4 is a screen diagram showing a display screen of the tablet (touch panel 21).
On the touch panel 21, a virtual space column 141, a progress state column 142, a target object column 143, a data input column 144, and an integrated server column 145 are displayed.

The virtual space column 141 shows a 3D-CAD display screen viewing the virtual space. The viewpoint of the virtual space column 141 is the viewpoint of the virtual camera updated in S113. In the virtual space column 141, a selection cursor 141a for selecting a target object in S114 is also displayed.
The progress state column 142 includes a list of states that can be taken as the progress state of the target object selected by the selection cursor 141a (14 states are illustrated in FIG. 4), a state ID (for example, “1”), and a state name. (For example, “material arrival”). In the progress state column 142 of FIG. 4, the smaller the value of the state ID, the earlier the process in the construction process (the state far from completion), and the larger the value of the state ID, the subsequent process in the construction process (the state close to completion). Indicates.

The target object column 143 displays the object ID of the target object selected by the selection cursor 141a, a button indicating the progress state (for example, “installing”), and a button for updating the viewpoint. It is a column.
When the “progress state” button is touched (input in S121), the state changes to the next state in the progress state column 142 (for example, “(6) Installation in progress” → “(7) Temporary welding”). .

  Every time the “viewpoint update” button is touched, a detection trigger in S111 occurs. Thereby, since the viewpoint of the virtual camera in the virtual space column 141 is updated at a timing desired by the worker 101, the viewpoint is stabilized and the viewpoint is updated as compared with the system that updates the viewpoint of the virtual camera excessively. Therefore, the battery of the tablet 1 is saved.

  The data input column 144 is configured by a button group (photographing, inspection input, progress input) for receiving input of each inspection data in S121. When these buttons are touched, an inspection data input screen (not shown) is activated. Each inspection data input via the input screen is associated with the object ID of the target object selected by the selection cursor 141a.

  The button group in the data input field 144 is activated when each inspection data corresponding to the button can be input (for example, the characters in the button are clearly displayed), and inactive when the input cannot be performed (for example, the button It is desirable to display the internal characters in a blurred manner. For example, when the progress state of the target object column 143 is other than “5: inspection” or “9: inspection”, the “inspection input” button in the data input column 144 is deactivated.

The integrated server column 145 is configured by a button group (data reception, data transmission) for instructing an opportunity to perform data communication with the integrated server 2. When “data reception” is touched, the reception process of S102 is activated. When “data transmission” is touched, the transmission process of S121 is started.
It should be noted that for each inspection data input process once, the “data transmission” in the integrated server column 145 may be touched once to start the transmission process of S121, or each input may be performed by a plurality of input processes. The transmitted inspection data may be collected and one transmission process may be activated.

FIG. 5 is a screen diagram showing a virtual space column in the display screen.
The displayed contents of the virtual space displayed in the virtual space column 141 change due to the viewpoint update processing of the virtual camera in S113. For example, in FIG. 5A, the viewpoint of the virtual camera is set to an initial value (overhead viewpoint from above the plant). Then, the virtual space displayed in the virtual space column 141 becomes a viewpoint when a part of the plant is viewed from the ground as shown in FIG. 5B by the viewpoint update processing of the virtual camera in S113.

  FIG. 5B is a display example in which the display control unit 22 directly displays the progress state in the virtual space column 141 so that the progress state of each target object shown in the progress state column 142 can be understood. For example, regarding the display of the three-dimensional shape of the container 153 supported by the bases 151 and 152, the display control unit 22 indicates that the bases 151 and 152 are in the progress state “6 (installation)” and the container 153 is in progress. The state “1 (material arrival)” is displayed on the touch panel 21.

  Such a display indicating the progress state of each target object is realized in various forms. For example, the progress state may be defined for each color, and the target object may be colored with a color indicating the current progress state. In FIG. 4, each progress state in the progress state column 142 is defined to be the previous process as the ID is smaller. However, the color indicating the current progress state is less conspicuous as the previous process (the color is lighter). Or darken).

Each progress status in the progress status column 142 also includes information (factory, site, etc.) indicating where the progress work is performed. For example, the progress state “1 (material arrival)” to the progress state “5 (inspection)” are performed at the factory.
Therefore, the progress state corresponding to the current position of the worker 101 in the real space (work is performed at the current position) and the other progress state (work is performed at another location) are displayed separately. Also good. For example, when the virtual camera reflects the position of the “site” instead of the “factory”, an object such as a building material that is operated in the “factory” has not arrived at the “site” at the present time.

  For this reason, in the “site” where the worker 101 is present, only objects (bases 151 and 152) that can actually be seen exist, but objects that cannot be seen in the virtual space (for example, containers 153) are also displayed. Therefore, the display of the container 153 that has not yet arrived at the “on-site” (the work is performed at the “factory”) is hidden, displayed transparently, or displayed less conspicuously than other objects. By performing the display, the worker 101 can easily grasp that the container 153 is an object that has not arrived at the “site” (an object that will arrive in the future).

  FIG. 6 is an explanatory diagram showing the correspondence between the real space and the virtual space different from FIG. FIG. 6A shows a situation where an operator 101 climbing a spherical tank in a real space plant on a staircase is photographing the construction object 102 near the top of the tank with the tablet 1. FIG. 6B shows the display contents of the virtual space column 141 calculated from the shooting contents (the viewpoint of the camera 24) of FIG.

FIG. 7 is a screen diagram showing a virtual space column in the display screen. The display control unit 22 displays the target object selected by the selection cursor 141a with respect to the three-dimensional shape data of each object shown in the virtual space column 141 of FIG. 101 is supported to visually detect the target object.
For example, the display control unit 22 also has the same virtual camera viewpoint when the near side container 171 is selected (FIG. 7A) and when the pipe 172 connecting each container is selected (FIG. 7). (B)) and when the back container 173 is selected (FIG. 7C), the selected target objects are highlighted with bold lines, and the unselected objects are transparently displayed with thin lines. .

  FIG. 8 is a screen diagram showing a display screen of the integrated server. This display screen includes a virtual space column 181, a progress status column 182, a target object column 183, a related photo column 184, a related inspection form column 185, a construction history column 186, and a report output column 187. Each is displayed.

The virtual space column 181, the progress state column 182 and the target object column 183 have the same display contents as the virtual space column 141, progress state column 142 and target object column 143 of FIG. That is, the 3D-CAD display of the virtual space can be viewed not only on the tablet 1 but also on the integrated server 2, and an object in the virtual space column 181 can be selected.
Since the installation position of the integrated server 2 is a construction office, the “viewpoint update” button in the target object column 143 for linking the real position and the virtual position is omitted in the target object column 183.

  The related photo column 184 is a display column for “related photo” in the inspection data for which input is received in S121. The operator 101 touches the related photo column 184 to select an image file of inspection data from a file dialog (not shown) for selecting an image file of a related photo captured by the camera 24 as an input target. .

  The related inspection form field 185 is a display field for a file (inspection form file) that has been “inspected” in the inspection data that is accepted in S121. The worker 101 touches the related inspection form column 185 to select a spreadsheet file (file with the extension “xls”) in which item values for the inspection items are listed as an input target (illustrated). Select a spreadsheet file for inspection data.

The construction history column 186 shows an update history of the progress state of the object indicated by the object ID in the target object column 183. When the “progress state” button in the target object field 143 is touched, the input control unit 23 associates the progress state of the transition destination with the date of the touched time (transition time), and sets the target object field. The update history of 183 is updated.
As described above, since a series of inspection data (corresponding to the object ID) related to the target object selected in the virtual space column 181 can be overlooked on the same screen, the construction state can be managed efficiently, Support early detection.

  Further, the report output field 187 displays a creation instruction button for creating various reports using the input inspection data related to the target object as a material (S123). As a result, it is possible to reduce the work time required for an operator to create an inspection report or the like at the site.

  When the “construction progress report” in the report output column 187 is touched, the integrated server 2 performs the 3D-CAD diagram color-coded by the progress from the inspection data read from the integrated database 2a and the construction of the selected part. A “construction progress report” is created in which the history and the photos of each construction history are linked. In the “Construction Progress Report”, photographs are written in the order of progress in the form of photographs when they arrive at the factory and photographs when they are processed.

  When “inspection report” in the report output field 187 is touched, the integrated server 2 links the information input to the inspection form from the inspection data read from the integrated database 2a and the photograph taken at that time. Prepared “inspection report”. The “inspection report” can be created when there is an inspection phase, and if it cannot be created, the “inspection report” button in the report output column 187 is invalidated (cannot be touched). .

  In the present embodiment described above, the virtual space column 141 is displayed on the touch panel 21 from the viewpoint of the virtual camera in which the actual position of the worker 101 is reflected in the virtual position (S113). Thereby, the worker 101 can immediately browse on the tablet 1 holding the virtual space in the 3D-CAD format reflecting his / her three-dimensional position and line of sight. Therefore, the operator 101 can accurately specify the object to be inspected while staying at a complicated construction site of the plant, thereby reducing inspection errors.

  Furthermore, as shown in FIG. 5B, the tablet 1 displays the progress state for each object in the virtual space column 141. Thereby, the progress management is linked with the display of 3D-CAD. Therefore, the worker 101 can grasp the progress of not only the object to be inspected but also the surrounding objects, and can improve the inspection accuracy of the object.

Then, the tablet 1 may refer to a place corresponding to the progress state of the object for each object, and the display form may be different depending on the object existing at the position of the viewpoint of the virtual camera and the object not existing. Thereby, not only the existing object but also the surrounding nonexistent object can be considered.
For example, the worker 101 confirms that a shield (such as a tree) existing around the bases 151 and 152 in FIG. 5B interferes with the container 153 to be transported, It can be grasped by comparing with a construction site in real space.
Alternatively, the worker 101 confirms the installation direction of the bases 151 and 152 in FIG. 5B and the installation direction of the container 153 to be carried on the display screen of the touch panel 21, and By comparing the above, it is possible to grasp at an early stage (before the container 153 is transported) that the installation direction of the bases 151 and 152 is inconsistent with the container 153 (reverse).

In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
