Description

  The present invention relates to an instrumentation system support apparatus, and more particularly, relates to the identification of a failure source in a plant instrumentation system and the efficiency of work related to the failure recovery.

  FIG. 9 is a block diagram showing an example of a conventional instrumentation system support apparatus. In FIG. 9, engineering information for operating the instrumentation system is created by the engineering function unit 102 and stored in the database 101.

  The engineering information stored in the database 101 is downloaded to the operation monitoring unit 103, the control arithmetic processing unit 104, the input / output module 105, and the like according to a request, thereby enabling operation control of the plant. The control arithmetic processing unit 104 exchanges various data with the operation monitoring unit 103 and the input / output module 105.

  A sensor terminal 107 such as a flow meter and an operation terminal 108 such as a control valve are connected to the input / output module 105 via a connection unit 106.

  The database 101 also stores plant design data created by the 3D CAD 109, various data such as setting parameters and calculation results related to the PID calculation processing of the PID calculation unit 110, various data of the simulator model 111, and the like.

  When the control arithmetic processing unit 104 detects an abnormality of the plant via the sensor terminal 107 or the operation terminal 108 during the operation control of the plant, an alarm is issued, and the contents can be checked by the operation monitoring unit 103.

  The alarm operating condition can be set in advance by the engineering function unit 102. For example, when the measured value of the sensor terminal 107 exceeds a certain value, the operation monitoring unit 103 is set to issue an alarm. The setting data (engineering information) is downloaded to the operation monitoring unit 103, the control arithmetic processing unit 104, and the input / output module 105, and then the instrumentation system is operated.

  The control arithmetic processing unit 104 constantly acquires the measured value of the sensor terminal 107 during operation of the instrumentation system via the input / output module 105, and issues an alarm to the operation monitoring unit 103 when the measured value exceeds the threshold value. I will inform you.

  Based on the alarm information displayed on the operation monitoring unit 103, for example, if there is an abnormality such as a crack in the piping, the maintenance staff takes measures such as repair. The location of the plant abnormality can be identified by alarm information.

  In Patent Document 1, by searching the detailed design book from the alarm signal name of the IBD (Interlock Block Diagram) which is an upstream book, the cause device of the alarm can be quickly estimated or the influence range An instrumentation system support device and a management maintenance method that can quickly investigate the problem are described.

JP2012-123500A

  However, since the alarm information displayed on the operation monitoring unit 103 is two-dimensional information without depth information, it is difficult to understand the distance in the depth direction. For example, when the location where an abnormality occurs is in a complicated piping group, it may be difficult to appropriately determine whether there is a space where maintenance personnel can enter or whether a replacement member can be inserted.

  Therefore, in such a case, generally, the physical state of the site is confirmed with reference to the design drawing of the plant created by the 3D CAD 109.

  However, the design drawings of the plant displayed on the 3D CAD screen are usually used by 3D CAD design operators who are experts on the road. For maintenance personnel who are not familiar with the 3D CAD screen, The screen display on the plant 3D CAD is very difficult to understand.

For this reason, there is a problem that it takes a lot of time to plan and execute the maintenance work.
The present invention solves such problems, and its purpose is to make it easy for maintenance personnel including maintenance personnel to quickly determine the physical distance and positional relationship between the location where a plant abnormality has occurred and its surroundings. The object is to realize an instrumentation system support device that can be accurately grasped.

It is another example of a display of a pipe line. It is another example of a display of a pipe line. It is a block diagram which shows an example of the conventional instrumentation system assistance apparatus.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing the main part of one embodiment of the present invention, and the same reference numerals are given to the parts common to FIG. In FIG. 1, the data link unit 201 is input with data of the database 101, data of the control processing unit 104, and 3D CAD data of the 3D scanner 202, and a 3D printer 203 is connected.

  The data link unit 201 associates the data of the database 101, the data of the control arithmetic processing unit 104, and the 3D CAD data of the 3D scanner 202 as necessary, and outputs the associated data to the 3D printer 203. Specifically, it is a tool for adding a mark to an abnormal part, for example, and the mark can be represented by a color, a symbol, a character, a protrusion, or the like.

  The 3D scanner 202 is used when it is desired to collate an actual plant with data obtained by linking 3D CAD data and an alarm signal. For example, piping may be deformed in a plant. The deformed pipe is scanned and captured by the 3D scanner 202, and the data linked with the 3D CAD data and the alarm signal is superimposed and 3D printed by the 3D printer 203.

  The maintenance staff confirms the design data of the plant to which the mark has been added as a 3D printed output by the 3D printer 203, so that the physical location and distance relationship between the location where the abnormality occurred and its surroundings can be Compared with the case of dimensional planar printing, it can be grasped more accurately.

  Data superposition can also be applied to investigate the cause of abnormalities. Specifically, in the data link unit 201, for example, the cursor is moved with a mouse or the like to the corresponding abnormality occurrence place marked with the 3D CAD data.

  FIG. 2 is a flowchart for explaining an operation example of the data link unit 201 of FIG. As a precondition, a device in which the PID calculation unit 110 is mounted on the design data created by the 3D CAD 109 is set in advance using the engineering function unit 102 or the like and stored in the database 101. The data link unit 201 acquires these stored data.

  First, alarm information is acquired from the control arithmetic processing unit 104 (step S1). Subsequently, a device that generates and outputs the alarm information is searched from the 3D CAD data (step S2). Then, a place to add a mark is determined from the position of the hit device, and a predetermined mark is added (step S3).

  For example, if there is a difference in the flow rate measured by installing two flow meters before and after the joint of the pipe, there is a possibility that a fluid such as a crack has occurred in the pipeline between them and the fluid is leaking. is there.

FIG. 3 is a specific example of a three-dimensional modeled object output from a 3D printer showing such an abnormal portion of the pipeline.
As a result, the maintenance staff can accurately grasp the abnormal part of the pipeline on the site based on the three-dimensional structure before going to the site. In addition, the identification display of an abnormal location is not restricted to coloring, A symbol and a character may be sufficient. In particular, adding marks such as symbols and characters is effective for printers that cannot perform color output.

FIG. 4 and FIG. 5 are also specific examples of a three-dimensional structure that is output from a 3D printer showing an abnormal portion of a pipeline.
In particular, as shown in FIG. 5, if the abnormal part A of the pipeline is output at the same scale together with the human-type image M of the worker, replacement parts and work equipment (not shown), the clearance and piping of the structure at the site It is possible to accurately grasp in advance the specific situation such as the size of the interval, and to efficiently plan and execute specific work contents of the maintenance work and how to proceed with the work.

  As for the abnormal location information, for example, by analyzing the vibration of the pipe using a vibration sensor and calculating the crack location, more accurate position information can be obtained.

  FIG. 6 is a diagram in which specific temperature distribution information in the pipeline shown in FIGS. 3 and 4 is visualized with a numerical value and a predetermined display color assigned according to each temperature, (a) is a front view, (b) ) Is a right side view.

  According to the front view of FIG. 6A, the temperature of the vertical pipe on the front side is 150 ° C., whereas the temperature of the horizontal pipe on the depth side is as low as 30 ° C. It can be seen that the risk is lower than that of the vertical pipe. The maintenance staff can grasp and identify the temperature distribution state in each part of the pipeline more intuitively than in FIGS. 3 and 4 which are simply binarized.

  Based on these temperature information, it is possible to make a maintenance plan that takes into account safety measures that prevent the user from inadvertently approaching a high-temperature pipe line.

  FIG. 7 is a diagram showing another example of the pipe line, and shows an abnormal part of the pipe line. (A) shows that the liquid in the pipe is flowing out, and (b) shows a crack in the pipe. Indicates that it is in.

  FIGS. 8A and 8B also show other display examples of the pipe, in which FIG. 8A shows that a hole is made in the side wall of the pipe, and FIG. 8B shows that the pipe is shifted in an oblique direction.

  By allowing the maintenance staff to take the modeling object printed out of these FIG. 7 and FIG. 8 by a 3D printer to the work site, it can serve as a map, and an effect of efficiently performing the work can be expected.

  Further, by 3D printing the 3D model in advance, for example, the 3D model can be photographed with a camera of a tablet terminal, and an abnormal part of the photographed 3D model image can be marked. In marking an abnormal part, the 3D model is collated with the position information of the abnormal part held by the data link unit 201 of FIG.

  By performing 3D printing in advance, there is a merit that a waiting time (for example, about several hours) required for 3D printing after the occurrence of an alarm does not occur, and appropriate measures against the occurrence of an alarm can be quickly performed. The downtime caused by abnormal operation of the mounting system can be shortened as much as possible.

  Furthermore, 3D modeling can be performed without going to the site by allowing workers to view the 3D model in a normal state that has been modeled and output by such a 3D printer with a goggle-type wearable computer mounted on the site. Information on anomalies occurring in the object can be visually confirmed, and maintenance work can be performed more efficiently.

  In the above embodiment, an instrumentation system including a 3D printer that outputs a 3D model is described. However, the 3D model is not limited to the output of the 3D printer. You may create it.

  As described above, according to the present invention, maintenance workers, including maintenance personnel, can accurately determine the location of an abnormality in a plant and the physical distance and positional relationship around it based on the 3D object. It is possible to realize an instrumentation system support device that can be grasped easily and can perform maintenance work efficiently.
