Description

  The present invention relates to laser measurement work for facilities such as power plants and chemical plants, and more particularly to a simulation apparatus that supports efficient laser measurement work planning.

  In facilities such as power plants and chemical plants, in order to grasp the current configuration of equipment, piping, etc., point cloud data on the surface of equipment, piping, etc. is acquired using a laser measuring device, and based on the coordinate data Work to create and update plant three-dimensional data (3D-CAD data) is being carried out.

  In general, laser measurement work requires a large number of man-hours from planning to implementation. In particular, it is necessary to perform laser measurement from a large number of measurement points in order to obtain the point cloud data of the surface of a plant having a complicated shape, which is constituted by a large number of devices and pipes. Here, if the measurement points are set improperly, it takes time to merge the acquired data by measuring the same part repeatedly, or a measurement omission occurs and the site is returned to the site for additional measurement. The number of work man-hours will be further increased. Accordingly, in order to reduce the number of laser measurement work steps, it is necessary to set measurement points that can acquire point cloud data without omission with a small number of measurements. An example of a measurement support apparatus that supports setting of measurement points is disclosed in Patent Document 1.

  Patent Document 1 can automatically select a viewpoint that allows a user (measurer) to grasp the measurement status of an object to be measured, and display three-dimensional shape data. A measurement support device that can increase efficiency is described.

However, in that case, it is necessary to consider the positional relationship in the Z-axis direction such as the height of each component and the height of the stepladder. In the example shown in FIG. 9, the simulation is executed every time one measurement point is added, but may be executed after adding a plurality of measurement points.

(Step S420)
In step S420, a measurement flag is set. The measurement flag here is a flag indicating whether or not each of a plurality of points constituting the surface of each component is included in the measurable range.

  Information on the measurement flag is set in the 3D-CAD data storage unit 401 of the storage device 400. FIG. 10 is a diagram illustrating a data configuration of the 3D-CAD data storage unit 401 in which measurement flag information is set. In the example shown in FIG. 10, each part is assumed to be composed of N points (point (1) to point (N)), and among the points (1) to (N), measurement is possible calculated in step S410. “1” is set to the measurement flag corresponding to the point included in the range, and “0” is set to the measurement flag corresponding to the point not included in the measurable range. In the example shown in FIG. 10, the surface of each component is assumed to be composed of N points for the sake of simplicity, but the number of points constituting the surface of the component is the size and shape of the component. Depending on. Further, as the number N of points constituting the surface is increased, the shape of the measurable range and the measurement omission range can be calculated more accurately. FIG. 10 shows the data structure in the state shown in FIG. 9E (the state in which the surfaces of the parts arranged in the measurement target area are all calculated as a measurable range). “1” is set to all the measurement flags (indicated by broken lines) corresponding to the points (1) to (N) of the parts for which “1” is set.

(Step S430)

(Step S510)
In step S510, the measurement coverage is calculated based on the measurement flag set in step S420. The measurement coverage here is an index value indicating the ratio of the number of parts of a component that does not include the measurement omission range to the number of parts of the component arranged in the measurement target area. A method for calculating the measurement coverage will be described with reference to FIG. FIG. 12 is a diagram illustrating a data configuration of the 3D-CAD data storage unit 401 in the state illustrated in FIG. In the example illustrated in FIG. 12, the number of parts arranged in the measurement target area (parts for which “1” is set in the measurement target area flag) is 8 (part IDs 101 to 104, 201, 202, 203, 601). ). On the other hand, the number of parts that do not include the measurement omission range (parts for which “1” is set for all measurement flags corresponding to the points (1) to (N)) is 2 (part IDs 101 and 201). . Therefore, the measurement coverage is 2/8 = 25%.

(Step S520)
In step S520, a message notifying the measurement coverage is created and displayed on the message display unit 13. The message display processing unit 202 reads a message template for notifying the measurement coverage from the message template storage unit 403. FIG. 13 is a diagram illustrating an example of a data configuration of the message template storage unit 403 in which various message templates are stored. In the example illustrated in FIG. 13, the message template storage unit 403 includes three types of message templates (a message template 403 a for notifying a measurement coverage, a message template 403 b for notifying a part including a measurement omission point, and a measurement count). The message template 403c) for notifying the work man-hour is stored together with the template ID. The message display processing unit 202 inserts the character string “25%” indicating the measurement coverage calculated in step S510 into the indefinite portion “??” of the message template 403a, and “the current measurement coverage is 25%. If you want to eliminate the measurement omission in the target area, please add or change the measurement point "message is created and displayed on the message display unit 13 of the display 1 (see FIG. 1).

  Note that the processing flow of step S500 shown in FIG. 11 is for displaying a message notifying the measurement coverage, but when displaying a message notifying the part including the measurement omission range, it is shown in FIG. Referring to the 3D-CAD data storage unit 401, a component including a measurement omission point (“1” is set in the measurement target flag, and “0” is set in any of the measurement flags corresponding to the points (1) to (N)). ”Is specified, and then a message is created by inserting a character string indicating a part including the measurement omission range into the indeterminate portion“ ?? ”of the message template 403b, and displayed on the message display unit 13. The process flow is as follows. When notifying the number of measurements and the number of work steps, the number of measurement points (seven in the example shown in FIG. 7) is specified with reference to the laser measurement device information storage unit 402 shown in FIG. After calculating the work man-hour based on the number, a message is created by inserting the number of measurement points and the character string indicating the measurement work into two undefined parts “??” of the message template 403c, respectively, and the message display unit 13 Is displayed in the processing flow.
