6) Parameter configuration table: all factors affecting the electrical schematic are extracted from the series of template electrical schematic, and are summarized into a parameter configuration table, wherein the factors affecting the electrical schematic mainly comprise: the same part, the influence of different models, multiple selection of one part, the presence or absence of the condition, or the other one, namely the two conditions;
7) CAD-VBA program: the series of template drawings and the parameter configuration table are associated in a CAD-VBA macro program development mode, and the program automatically generates an electrical schematic diagram corresponding to the series of template drawings under the support of the series of template drawings through the parameter values in the parameter configuration table;
8) Electrical schematic diagram: under the function of CAD-VBA program, a required electrical schematic diagram is obtained and can be directly printed.
Fig. 2 is a principle of automatically generating an electrical drawing by a program, as shown in the following: the influencing factors in the parameter configuration table mainly comprise the following 5 types: the effects of "same part", "different model", the "one-out-of-multiple" part, the "with or without" case, the "not-that is" one-out-of-multiple "case. For the same part, the program does not process, and the figures are the same by default in the electrical schematic diagram, and all devices are common; the program is written according to the changing condition of drawings caused by the influence of different models on the series of equipment; for example, a large-load elevator is not easy to manually rotate, a power distribution motor rotating structure is needed, and wiring diagrams of the mechanism are different; a "one-out-of-multiple (one-out-of-multiple)" section, the program calculating and displaying a drawing of the apparatus in this case based on the values in the one-out-of-multiple; "with or without" such parameters if "with" is selected, the program adds and displays the portion of the drawing in the manifest; "not this is the case of" alternative "which is similar to" alternative "and directly shows the drawing corresponding thereto; when the program processes the same part, the fixed drawing is directly displayed without any change; when the program processes the condition that other 4 classes have changes, the program directly operates fixed positions in a series of template drawings, and generates a final electric list in a mode of layer development, page replacement, block replacement, super block, text replacement and the like according to a change rule.
Taking a fixed elevator without a PLC control system as an example, after analysis of series equipment according to the method of the invention, the following conclusion is drawn: the lifting power is controlled by the oil pump hydraulic pressure, 2 conditions exist/not (the power of the turnover mechanism is provided by the lifting hydraulic pressure), 2 conditions exist/not (the power of the rotation mechanism is provided by a common three-phase motor), and 3 conditions exist in the blanking valve, namely, the blanking valve is not provided with a pneumatic butterfly valve or an electric butterfly valve; 3 nonstandard parameters can be refined in the electrical parameter table (as shown in fig. 3);
combining the nonstandard factors and the original electrical schematic diagram to distinguish a standard drawing and a nonstandard drawing, thereby preparing a template drawing of each model; comparing the drawings, and combining the non-standard parameters to extract drawing influencing factors, wherein the factors are shown in fig. 4; comparing fig. 3 and 4, it was found that a "device model" factor was added, since for devices above the heavy load 1000, the rotating mechanism would necessarily be present.
After determining the drawing influencing factors, combining the template drawings of each model, and writing a complete series of template drawings according to the series of equipment drawing logics. The drawing is to be classified, the local drawing (modularized drawing) under each influencing factor is made and placed in a fixed area or page, and the module drawings are made into the editable objects of programs such as different layers, superblocks, common blocks, texts with attribute values, common editable texts and the like, and the objects are used as the acting objects of the CAD-VBA program.
After the series of template drawings are finished, drawing influencing factors are arranged in a certain page in the drawings, and a hook or selectable pattern is made, so that a designer can conveniently select; and then writing a CAD-VBA program, associating a parameter configuration table with a series of template drawings, and automatically generating a final electrical schematic diagram under different parameter configurations by editing an editable object made in the template drawings.
The foregoing is merely exemplary embodiments of the present invention, and it should be noted that various changes, modifications, substitutions and alterations can be made herein by those skilled in the art without departing from the technical principles of the present invention, which are also intended to be regarded as the scope of the invention.
