Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for calculating a reverse shadow, and particularly to a building that can be built according to a sunshine time on a measurement line in a site use plan or a building regulation intended by a designer. The present invention relates to a method for calculating a reverse shadow for planning and designing.

[Conventional technology]

Conventionally, this type of shade calculation is performed by defining the building shape, performing the shade calculation, intuitively cutting or adding the building shape until the desired sunshine is obtained, and performing the shade calculation repeatedly. I want a sunshine building shape.

[Problems to be solved by the invention]

However, the above-described conventional reverse shadow calculation is based on a site use plan intended by the designer, and is required for a designated checkpoint (measurement point) during a sunshine period (morning sun, daytime, sunset).
It also has the disadvantage that it is not possible to obtain a building shape for the most effective land use and to output the resulting shape to an output device.

An object of the present invention is to construct a building by determining a plurality of measurement points from fixed conditions such as a site and building regulations, and checking a shading state at a measurement point for a unit in which a construction target area is equally divided by time zone. An object of the present invention is to provide a reverse shadow processing method for finding a shape.

[Means for solving the problem]

The reverse shadow calculation processing method of the present invention, the site data, the peripheral map data and the building regulation data, the measurement point pitch, the measurement time pitch, the unit division pitch of the construction target area, and the volume cut method model in the information processing device. To set the measurement point and the division unit, delete the unit that generates the shade in the order of time division for each measurement point until the legal conditions are satisfied, and complete the unit deletion for all the measurement points. It is configured by outputting a unit that has not been deleted at the time as a buildable shape.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram of an example of a calculation processing device for performing a reverse shadow calculation process.
A keyboard 22 for inputting operation commands such as stop / abnormal processing and data necessary for calculation processing, a map 23 depicting a site shape, a tablet 23 on which symbols, characters, etc. are arranged, and a required position and symbol of the tablet 23 are displayed. It comprises a light pen 24 to be hit, a disk device 25 for storing the coordinate values of the site shape and the calculation result, a graphic display 27 for displaying the calculated building shape, and a printer 26 for outputting the progress of the calculation.

The central processing unit 21 operates according to the command of the keyboard 22 according to the stored program, calls the corresponding registration data from the disk device 25 based on the data input by the tablet 23 and the light pen 24, processes the data, and outputs the data to the graphic display 27. Display or operate print 26 to create a hard copy. Also, it performs site input data check until the start of reverse shadow calculation, oblique line restriction calculation, site input data check until the start of reverse shadow calculation, diagonal line limit calculation, and reverse shadow calculation processing.

FIG. 1 (a) is a flowchart of a program of an embodiment for performing a reverse shadow calculating process using the calculating device of FIG. 2, and the present invention will be described with reference to FIGS. 1 (a) and 2 hereinafter. The operation will be described. First, various constants and constants of regulation data are set as initial values (step). Next keyboard
Enter the site data name and processing date to be processed using 22, set the site drawing using the tablet 23, hit the site shape and neighboring shapes with the light pen 24, and follow the building guide (Shade regulation, restricted zone, etc.) is input (step). Next, in accordance with an instruction from the keyboard 22, the calculation of the deemed boundary line and the measurement line and the calculation of each oblique line restriction are performed (step), and the calculation result of the oblique line restriction is displayed on the graphic display 27 as contour lines (step). Next, it is confirmed whether there is no problem in the calculation result and the input data (step). If there is a problem, return to the step and reset the data. After confirming the data, the site data and the legal data are registered in the disk device 25 (step).
Next, a reverse shadow calculation instruction is issued from the keyboard 22. This calculation instruction is performed by instructing the name of the site data set to be calculated for the reverse shadow, the measurement point pitch, the measurement time pitch, the vertical and horizontal pitch, and the volume cut method of the building (step). As a result, the inverse shadow calculation described later is performed (step), and the outline view (perspective view) of the building shape after volume cutting is displayed on the graphic display 27. The plane shape of each floor can also be displayed for each floor (step). Further, the confirmed data is registered in the disk device 25 (step).

In addition, the volume cut method of the inverse shade calculation is generally divided into a minimum unit cut type, an Asahi type, a daytime type, a sunset type, and a plan type. This is a method for finding a building with the largest volume that satisfies the above conditions. The Asahi pattern is a method in which a designated time zone is divided into fixed time intervals, and the volume of the building is cut so that light rays in the morning time zone hit the measurement points. The daytime type and sunset type are also methods of volume-cutting the building so that the light rays in the daytime and the light in the evening light hit the measurement point. In addition, the plan type instructs the building not to be built (or to build the building to the maximum extent) on the designated site based on the site usage plan planned by the designer,
According to the plan, it is a method to obtain the shape of the building to be built on the site.

FIG. 1 (b) is a flowchart of a program of one embodiment of the step inverse shadow calculation of FIG. 1 (a). Hereinafter, the inverse shadow calculation will be described with reference to FIGS. 1 (a) and 1 (b). explain. First, necessary measurement points are generated from the site data, regulation data, and various input data of the steps registered in the step (step). Next, the calculation target area is equally divided and a unit number is given (step). This division is, for example, X,
Each unit is divided into 3 m units in the Y and Z axis directions, and unit numbers 1 to 1000 are given. Next, it is determined whether or not the regulation condition is satisfied at all the measurement points (step), and a unit cut at the measurement point is performed for an unmeasured point (step).

This unit cut method is divided into 30 minute intervals, for example, from 8:00 to 16:00 according to the steps,
As a section, the number of units where a shade occurs in each section is checked. Therefore, if the unit cut method is the designation of the minimum unit cut type, the unit which caused the shade in the section having the smallest number in the section is deleted. If the unit cut method is the designation of the Asahi type, the unit that has generated the shadow is deleted in the youngest numbered section where the shadow is generated. If the unit cut method is the setting of the sunset type, the unit that has generated the shadow is deleted in the oldest numbered section that has generated the shadow.
Furthermore, if the unit cut method is daytime, the unit that has generated the shadow in the ninth section where the shadow is generated or the section closest to this section is deleted. Furthermore, if the unit cut method is the plan type, the unit is deleted by a combination of the specified limit and the above various types.

Next, the shade time at the measurement point is calculated (step), and if the shade time is not within the regulation, the process returns to the step, the unit in the next section after the previously deleted section is deleted, and the step is again performed in the step. The shadow time is calculated, and it is checked in a step whether the shadow time is within the regulation. This step and the above steps are repeated, and if the shade time is satisfied at one measurement point, the measurement point is moved to the next and the process returns to the step (step). In this way, if the regulation condition is satisfied at all the measurement points in the step, the process proceeds to the step and the step.

〔The invention's effect〕

As described above, according to the present invention, by inputting a site drawing with a tablet and a site shape with a light pen, a given site shape is considered in accordance with building regulations and a site usage plan intended by a designer is considered. Thus, there is an effect that it is possible to obtain a building shape that can secure the sunshine time at a designated point (measurement point) without performing intermediate processing by hand.
