[0007] 4. When the components on the panel and backplane of the electrical control box and cabinet are not fully filled, the principle of reserve needs to be applied. The positioning of the components and the determination of the dimensions of the clamping rail and the slot need to be considered by the designer
Occupancy of layout components and internal layout status are not intuitive

Embodiment 1
[0074] A. According to the technical parameters required for the design of the installation layout drawing, with the trunking inside the cabinet as the regional boundary, based on experience and regulations, initially determine the division of the cabinet area, and determine the area parameters according to the requirements of the alignment method.
[0075] Take the spatial distribution of the 8-sided area as an example (such as image 3 ), which has 8 boundary lines, and determines the vector in a clockwise manner form a closed area. At the same time, the area S can be calculated 0 , the geometric expectation center (X 0 , Y 0 ) selection mode is as follows:
[0076] 1) Align the center and select the diagonal intersection point.
[0077] 2) Right center alignment, select midpoint of the line segment.
[0078] 3) Align left center, select midpoint of the line segment.
[0079] 4) Align top and center, select midpoint of the line segment.
[0080] 5) Align botto...

The invention discloses a method for generating electrical control box and cabinet installation and layout drawings, which includes two parts: area division and layout of combined modules in the area. The automatic layout method of space optimization is based on the minimum residual variance method to automatically layout the module components in each area. Compared with the traditional installation layout diagram, the design method of the present invention is simpler, the design efficiency is greatly improved, the design quality is guaranteed, the design differences caused by the personal level of the designers are avoided, and the professional skill requirements for the designers are reduced. The workload and pressure of design, proofreading, and review are greatly reduced. Fully realize the automation and intelligence of installation layout drawing design.
Description
technical field [0001] The invention belongs to the field of industrial electrical automation hardware design, and in particular relates to a method for generating automatic layout and drawing of installation layout diagrams of electrical control boxes and cabinets. Background technique [0002] The installation layout drawing is mainly used to indicate the actual location and installation requirements of all components on the electrical control equipment, and to provide necessary information for the manufacture, installation and maintenance of electrical control equipment. [0003] The design elements of the installation layout drawing often involve the following contents: [0004] 1. Selection of electrical control boxes and cabinets: Different selections are due to different sizes of panels and backplanes, different control schemes, different control objects, and different device layouts. [0005] 2. Selection of devices: different device types, different sizes and occup...
