  Each step described below is performed when an operator operates and inputs information on the operation input unit 103 while viewing a display screen such as a building graphic displayed on the display unit 104.

  As a building figure creation step, first, in step S301, a drawing scale is set. If printing of various drawings is required, the paper size is set, and a desired scale and a desired paper size are set. In step S302, a required building graphic is called out from the drawing data stored in the database 102, and the building graphic called in to set the lightning protection equipment and the lightning protection range is displayed on the display unit 104. In step S303, the height of the building figure called in step S302 is set and a 3D perspective view of the building figure is created. In step S304, it is confirmed whether or not there is a tower on the roof of the called building figure. If there is a tower, the process proceeds to step S305. If there is no tower, the process proceeds to step S306. In step S305, as in step S303, the height of the tower figure is set and a building figure with a tower is created.

  As a lightning arrester drawing step, in step S306, any one of a lightning arrester, a horizontal conductor, and a mesh conductor is drawn at a desired location of the 3D building figure created in the building figure creating step.

  As a lightning protection protection range designating arc drawing step, in step S307, a protection level (sphere radius) corresponding to the building from each of the sphere radii 20m, 30m, 45m, 60m corresponding to the four types of protection levels based on JIS standards. ) Is set. In step S308, the spherical radius set in step S307 so that the building graphic in which the lightning protection device is drawn in step S306 is in contact with the ground and the lightning protection device in the building graphic, or two or more lightning protection devices at the same time, Then, by drawing an arc that is a part of the scaled sphere set in step S301, the lightning protection range on the building graphic side of the arc is indicated and displayed. In the first embodiment, the protection level is set in step S307, but it may be set in the steps up to the previous stage.

  In step S309, whether or not the lightning protection area and the lightning protection range displayed in step S308 are desired, that is, whether or not the entire building graphic is protected against lightning. The determination input by the operator is discriminated. If the lightning protection equipment and the lightning protection range are desired, the process proceeds to step S310. If the lightning protection equipment and the lightning protection range are not desired, the process returns to step S306.

  As a rotating sphere drawing step, in step S310, when the lightning protection facility and the lightning protection range are determined as desired in the lightning protection range determination step, the desired figure of the lightning protection device and the lightning protection range are obtained. On the other hand, if the operator selects whether or not to draw the rotating sphere and does not draw the rotating sphere, the process ends, and if it is selected to draw the rotating sphere, the process proceeds to step S311 and is converted to 3D. A rotating sphere is drawn with respect to the building figure in the perspective view on which the building figure is displayed so as to be in contact with the ground and the lightning arresting equipment in the building figure or two or more lightning arresting equipment simultaneously.

  Next, in the lightning strike protection simulation system based on the rotating sphere method according to the first embodiment, an operation for setting the lightning protection equipment and the lightning protection range based on the rotating sphere method will be described with reference to FIGS. .

  First, when creating a new drawing, the operator sets a paper size and a drawing scale (step S301), and calls a building figure 201 for setting a lightning protection range and a lightning protection facility from the database 102 (step S302). Then, a perspective view such as a building figure 202 is created from the called building figure 201, the height of the building figure 202 is set by an operator input, and the called building figure 201 is converted into a 3D building. The figure 203 is created (step S303). Also, the operator checks whether or not there is a tower in the called building graphic 201 (step S304). If there is a tower, the height of the tower plan 201a is set on the 3D building graphic 203 by the operator's input. Then, the building figure 204 with a tower is created (step S305).

  Next, the building figure 205 with a lightning arrester is created in which the lightning arrester 206 and the horizontal conductor 207 are drawn on the 3D building figure 203 or the building figure 204 with a tower by an operator's input (step S306). Then, among the four types of protection levels defined in the JIS standard, the protection level of the building is set by the operator (step S307), and the arc 208 having a sphere radius corresponding to the set protection level is set to the earth. The lightning protection range 209 is displayed by drawing at a desired location by an operator input so as to contact with the lightning protection device or two or more lightning protection devices at the same time (step S308). Then, the operator checks whether or not the lightning protection equipment and the lightning protection range are desired (step S309). If the lightning protection equipment and the lightning protection range are desired, the lightning protection equipment and the lightning protection Complete the protection range setting. At this time, if the lightning protection equipment and the lightning protection range are not desired, the process returns to step S306 and the lightning protection equipment is set again. Thus, step S306 to step S309 are repeatedly performed until a desired lightning arrester and a lightning protection range can be set.

  Next, after completing the setting of the desired lightning protection equipment and the lightning protection range in step S309, the operator selects whether or not to draw a rotating sphere on the building figure 205 in which the lightning protection equipment and the lightning protection range are set ( In step S310), if it is selected to draw a rotating sphere, the rotating sphere 211 is drawn on the building figure 205 (step S311), and if the rotating sphere is not drawn, the process ends.

  By performing the above operation, a desired lightning protection range and lightning protection equipment for the building can be obtained. In addition, when outputting drawing data created by the above steps, such as during printing, the data is output to the data output unit 105 as needed.

The lightning protection equipment and the lightning protection range can be set and confirmed from the viewpoint, and the lightning protection equipment and the lightning protection range of the entire building can be clarified.

  In addition, the scale of the drawing is desired, and the scale may be changed during the simulation, so that it is possible to easily set the lightning protection equipment and the lightning protection range even in the invisible details of the building. .

  The lightning protection simulation system according to the rotating sphere method according to the first embodiment of the present invention as described above creates a 3D building figure from the called floor plan building figure, and rotates the entire building figure with a predetermined sphere radius. Since the arc that is a part of the sphere can be drawn, it is possible to simulate the lightning protection equipment and the lightning protection range of the entire building based on the rotating sphere method, and the lightning protection equipment and lightning protection of the whole building. The effect that the protection range can be clarified is obtained.
