DE10012620A1 - Computer-aided design program for heating, ventilation, sanitation and electric building systems, enables drawing of particular pipe or wiring line system and switching to other line system without restarting program - Google Patents

Abstract

The CAD program calculates a complete line network of a process during the drawing of a particular line system e.g. sanitation, with the possibility of switching between other line systems without restarting the CAD program. The calculation for sanitation drawing is stopped to begin calculation for heating or ventilation. The basic plan of the chosen line system fades into the foreground for processing corresponding calculations, using a mouse as main input device. The CAD program determines the necessary line cross-sections and their amounts in preparing conductor plans.

Description

The software for the calculation of heating, ventilation and Sanitary facilities are very complicated to use and very expensive. They are based on a table representation. In order to provide the necessary information, specialist knowledge of each is required selected trade necessary. The program can only run the pipeline network after it has been fully specified to calculate. The "pre-made drawing" or sketch must then be corrected by hand. To the In the end, a line diagram may have to be drawn. It is in all known programs necessary to do at least two operations to create a drawing and a corresponding one To create calculation.

The invention specified in claim 1 is based on the problem, the plurality of Ar to reduce work processes, to save time and to improve the economy by using to significantly improve unskilled workers.

These problems are solved by the features listed in claim 1.

The advantages achieved by the invention are, in particular, that several work processes and in the context the use of highly qualified people in the creation of technical  Calculations and drawings in the field of home automation can be significantly reduced and thus the increasingly important economic cost factors will wear.

Fig. 01 shows a simple diagram of a closed circuit with a pump P. B. be a scheme for a heating circuit or a hot water pipe with a circulation pipe. There are also open circles, such as B. ventilation, cold water pipe, etc. possible.

The first novelty in the program is that the calculation of a network while drawing is carried out automatically and associatively. This means that the information with the keyboard ent fall. Every part of a drawn line or an entire line is calculated immediately and the Er results saved.

To use the program, only drawing skills are necessary. The information is given mostly with the mouse, without having to fill out a table; then it's just a choice of the product. When choosing a trade, e.g. B. Sanitary are all ge automatically Drawn routes recognized as water pipes and the corresponding calculation in the background carried out. That is, when drawing a line, the program knows that it is, for example a water pipe acts and performs the necessary calculations dynamically and in parallel, weh by "dragging" with the cursor, in the background.

After clicking on the line with the mouse cursor, a window opens and the calculation results can be read and placed in the drawing automatically or by hand.

When drawing lines, it is possible to display and parallel lines at the same time at different levels. This is important when transferring the drawing to existing floor plans. In this way, all cables that are actually installed on one level (e.g. in the screed) are also installed the floor plans.

Of course, different macros can be inserted at any point, such as shut-off arm turen or other line installations, which immediately be with the calculation running in the background be taken into account. The connection with pipes is automatic.

The second novelty is the switchable animation. The animation can be done while drawing, d. that is, during the calculation or at the end so that the current or entire calculation results can be continuously monitored visually.

The principle of the program is that the routes marked with letters on picture 01 can be assigned to any length.

The calculation is only carried out for the specified lengths, i.e. i.e., scale independent. After the calculation, the resulting drawing can be edited to scale and after a change Conversion from DXF format to a floor plan or 3D drawing in a CAD program be inserted.  

The program can also be used in all known CAD programs via the so-called C interface eta be bliert so that the user all practiced functions of the existing CAD program can use.

In practice, in an engineering office, this means that a technical draftsman or can completely plan and tender a sanitary facility. Calculation and creation of the Drawing are done in one operation.

The resulting advantages are obvious: time and cost savings of over 50% Operation of not highly qualified workers and coupling of drawing and calculation in one operation.

Another advantage over all existing programs is that this ADC Internet Active (IA) program. This means that every user on the Internet does that Program can use. The program is only used by the user for the time of use rents. The calculations performed are temporarily stored in a central computer and released for later retrieval. The overall or partial results can be obtained from the User can be printed out. A hotline is available to users during the calculation judges. The user of the program can contact the hotline every second and solve a problem on the screen together.

An embodiment of the process of the invention is shown in Figure 01 and will be described in more detail below.

When clicking the route L z. B. be specified that it is 5.45 m long. With the function "Insert" can insert additional sections or split the existing lengths. The small circles show nodes. The nodes always arise when connected to the line something (e.g. a tap) is connected or a new line is inserted. The so ent Known nodes are automatically provided with circles and serial numbers. in the The end result is a finished strand scheme.

Claims (1)

1. ADC IA computer program for simultaneous drawing and calculation of heating, sanitary, ventilation and electrical house systems for engineering offices, executing companies and architectural offices for determining necessary line cross-sections and their quantities as well as creating line plans, characterized in that the program in one operation while drawing a pipe network fully calculated with the ability to switch between the individual trades with a key combination, which in practice means that the calculation started z. B. for plumbing must not be completed and the program must be restarted to make a calculation for z. B. to start heating or ventilation or to be able to track it, but only a different basic scheme matching the selected Ge plant is displayed in the foreground and the associated calculation is further processed using the same method as before, intuitively and using the mouse as the main input device .
