Description

Technical Field

[0001] The present invention relates to the field of BIM technology, and in particular to a method and system for automatically generating a fire alarm system diagram based on BIM. Background Art

[0002] The fire detection and alarm system is the most basic building fire protection system to ensure the safety of people's lives because it can detect the initial fire of the protected object in a timely and accurate manner and respond to the alarm, so that people in the building have enough time to evacuate to a safe area before the fire develops and spreads to a level that endangers life safety.

[0003] With the development of BIM technology, its application in the construction field is becoming increasingly widespread. However, construction based on fire detection and alarm equipment in a 3D model requires the creation of a 2D system diagram for the fire detection and alarm system. However, in traditional design work, designers draw the relevant graphics for the fire alarm system by reading 2D CAD drawings of the building structure, then manually observe and determine the device connections, and finally manually draw the system schematic using CAD software. This method consumes a considerable amount of time and energy in repetitive, mechanical actions, resulting in low efficiency. Furthermore, the human brain is clearly not capable of handling such a large and complex fire alarm system, making it prone to errors and inefficient. Summary of the Invention

[0037] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0038] The embodiment of the present invention is a method for automatically generating a fire alarm system diagram based on BIM. Figure 1 Shown, including:

[0039] S1. Set style: Set the style of the automatic fire alarm system diagram according to the installation location of the automatic fire alarm system, including residential style and other location styles.

[0040] The table headers of the residential fire alarm system diagram include the equipment table header and the floor table header, while the table headers of the fire alarm system diagrams of other places include the equipment table header and the fire partition table header;

[0041] The automatic fire alarm system diagram is classified into two forms according to the installation location, namely residential form and other place form.

[0042] The differences between the automatic fire alarm system diagrams for residential and other types of places are: the types of equipment to be counted and the counting methods are different. The automatic fire alarm system diagram for residential needs to read the floors and count the number of equipment and other information by floor. The automatic fire alarm system diagram for other types of places needs to read the fire zones and count the number of equipment and other information by fire zones.

[0043] S2. Generate floor headers or fire partition headers: Read the floors or fire partitions included in the three-dimensional model according to the style of the automatic fire alarm system diagram, and generate floor headers or fire partition headers;

[0044] The attribute information of the 3D model can be read to determine the floor or fire zone to which it belongs. Reading the floor or fire zone can help determine the row header of the table.

[0045] S3. Configure the device header: Customize the configuration information of the device header in the interactive interface. The configuration information includes the device type, device legend, connected module boxes, and connection lines corresponding to the device header in the 3D model;

[0046] Part of the configuration information of the device header of the custom setting is as follows Figure 2 The equipment header includes area alarm, fire terminal box, short-circuit isolator, fire broadcast, fire telephone, smoke detector, heat detector, sound and light alarm, manual alarm with telephone jack, fire hydrant button, pressurized air supply vent, non-fire distribution box and video intercom for unit door opening, etc.

[0047] Among them, the fire terminal box and short-circuit isolator are generally set in the electric well or distribution room, and the equipment headers of the fire terminal box and short-circuit isolator are merged into the electric well or distribution room. The electric well or distribution room is generally located at the front of the table.

[0048] The module box includes I modules, O modules and I / O modules.

[0049] The connection lines are set up according to the purpose, and the connection lines include power trunk line D, signal bus S, fire broadcast bus BC, fire telephone bus F, fire fan direct control line C, direct pump start line Q and communication bus X.

[0050] S4. Generate a table: Generate table lines according to the floor table header or the fire zone table header and the equipment table header to obtain a table.

[0051] The equipment headers are distributed in columns, and the floor headers or fire partition headers are distributed in rows. Once the equipment header, floor header or fire partition header is determined, the number of rows and columns of the table can be determined, and the table lines can be completed to obtain the table.

[0052] In the residential fire alarm system diagram, the equipment header is set in the first row, such as Figure 3 As shown; in other fire alarm system diagrams, the equipment header is set in the last row, such as Figure 4 shown.

[0053] S5. Generate table cell information: Count the equipment types and quantities corresponding to each floor or each fire zone in the three-dimensional model based on the equipment table header, draw the corresponding equipment legend and the corresponding connected module box in the corresponding cell of the table, and mark the quantity;

[0054] According to the equipment header, the corresponding equipment type and quantity of each floor or each fire zone in the three-dimensional model are counted. According to the configuration information, the corresponding equipment legend and the corresponding connected module box are drawn in the corresponding cell of the table, and the number of the equipment type counted on the current floor or current fire zone is marked next to the equipment legend, so as to extract and convert the information in the three-dimensional model into the table cell, such as Figure 3-5 shown.

[0055] For example, when counting a water flow indicator, when drawing a water flow indicator legend, it is also necessary to draw a legend for the I module box connected to the device, and mark the quantity × 1 next to the legend.

[0056] S6. Generate connection relationships: Draw a graphic of the fire control room in the table based on the floor or fire zone where the fire control room is located in the 3D model; draw a vertical bridge including all connecting lines in the cell corresponding to the power shaft or distribution room; the vertical bridge is connected to the graphic of the fire control room, and connecting lines corresponding to the equipment type are drawn on the sections belonging to each floor or fire zone, and connected to the legend in the cell;

[0057] According to the floor or fire zone where the fire control room is located in the three-dimensional model, draw the fire control room graphic on the corresponding floor or fire zone in the table; the fire control room graphic is generally represented by a box. According to the location of the fire control room in the three-dimensional model, draw the fire control room graphic on the corresponding floor or fire zone, such as Figure 3-5 shown.

[0058] Draw a vertical bridge including all connecting lines in the corresponding cells of the electric shaft or distribution room; the vertical bridge contains all the connecting lines: 7 main lines including power trunk line D, signal bus S, fire broadcast bus BC, fire telephone bus F, fire fan direct control line C, direct pump start line Q and communication bus X.

[0059] All connection lines are output from the fire control room, pass through the vertical bridge, and are connected to different types of equipment respectively; therefore, the graphic of the vertical bridge connecting the fire control room is drawn out from the corresponding main line among the 7 main lines, and is connected to the equipment legend in the corresponding cell or the module box connected to the equipment on each floor or the section belonging to each fire partition. The legend in the cell includes the equipment legend or the module box legend.

[0060] S7. Output a two-dimensional diagram of the automatic fire alarm system.

[0061] The output of the residential fire automatic alarm system is as follows Figure 3 As shown; Fire alarm system diagrams for other locations are as follows Figure 4 shown.

[0062] Finally, it should be noted that the above-mentioned control method can be converted into software program instructions, which can be implemented by running a system including a processor and a memory, or by computer instructions stored in a non-transitory computer-readable storage medium. The above-mentioned integrated unit implemented in the form of a software functional unit can be stored in a computer-readable storage medium. The above-mentioned software functional unit is stored in a storage medium, including a number of instructions for enabling a computer device (which can be a personal computer, a server, or a network device, etc.) or a processor to perform some steps of the method described in each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM), random access memory (RAM), disk or optical disk, and other media that can store program codes.

[0063] In summary, the above-mentioned method and system for automatically generating a fire alarm system diagram based on BIM has the following beneficial effects:
