The present invention is a refrigerant pipe ( In modeling of liquid pipes, gas pipes), drain pipes, outdoor and indoor unit placement, and roof exposed pipes, branch connectors according to existing part combinations can be replaced with special family parts to improve material savings and efficiency, and calculate and manage the quantity. The main components of the technology include the basic information creation module (110), modeling module (120), family formation module (130), and quantity calculation module (140), as well as the recommendation module (150) for improving economic efficiency. , Equipped with a parts ordering module (160).

The basic information creation module 110 is configured to input outline information including the structure, size, number of floors, and related drawings of the target facility.

Figure 3 is an example of overview information according to an embodiment of the present invention. The overview information includes the design name of the target facility, site location and area, construction outline including the local district, use, structure and scale of the building, and architecture. It includes information such as building size and floor, including area, building-to-land ratio, and floor area ratio. At this time, the overview information includes a drawing of the facility and may include GRID, floor plan, level, front view, and side view, as well as isometric projections.

The modeling module 120 is intended to apply a cooling, heating and air conditioning system to the drawing of the facility, and includes an equipment arrangement unit 121 and a piping modeling unit 122 in detail.

The equipment arrangement unit 121 is configured to arrange cooling and heating air conditioning system equipment based on the overview information. In the present invention, the equipment is basically an outdoor unit and an indoor unit, and the equipment is placed at a desired location on the drawing according to the characteristics of the air conditioner and the building.

The pipe modeling unit 122 is configured to arrange pipes with pipe diameters set for each section based on the equipment and model pipe elements. In an embodiment of the present invention, the piping elements include a refrigerant pipe including a liquid pipe and a gas pipe, a drain pipe, and an exposed pipe tray in the roof layer.

Figure 4 is a conceptual diagram of modeling according to an embodiment of the present invention, Figure 5 is a diagram explaining the types of pipes according to an embodiment of the present invention, and Figures 9 to 11 are exemplary diagrams of modeling according to an embodiment of the present invention.

The refrigerant pipe is a pipe that transports refrigerant between the condensing coil and the fan or blower, and is composed of a liquid pipe and a gas pipe in the refrigerant pipe and is colored in light green. In addition, the drain pipe is a pipe installed to drain water containing foreign substances out of the pipe after burying the pipe that transports the collected water underground, and is indicated in light blue.

These piping elements connect the equipment previously placed through the equipment placement section in the shortest possible distance, and are modeled by combining straight sections and curved sections according to the shape of the building and placing them buried in the building structure or exposed to the outside. As mentioned earlier, this modeling is basically done on drawings, so the overall pipe length can be calculated along with inputting the specifications of the piping elements being modeled.

The family formation module 130 is for determining the detailed connection relationship of piping elements modeled through the piping modeling unit and applying the family parts to the location where the straight pipe is bent or branched, and is composed of an element extraction unit ( 131) and a family forming unit 132.

The element extraction unit 131 is configured to analyze the pipe elements and extract straight portions of the pipe, curved pipe portions at bent locations, and branch portions at branching or joining locations. That is, the element extraction unit 131 analyzes the piping elements modeled through the piping modeling unit 122 and confirms detailed connection relationships, largely dividing or combining the straight portion of the pipe and the curved pipe portion at the bent position. Identify elements such as reducers with different pipe diameters, as well as branch locations.

In the process of installing pipes in a building, in the case of straight pipes, the length is long, so no separate parts are required other than the connectors that interconnect the pipes, but in the case of curved pipes or branch outlets, separate parts such as conventional elbows or tees are required. This is necessary, and the same applies to reducers with different pipe diameters. The element extraction unit 131 analyzes the location and number of curved pipes and branch parts that require such connectors, excluding straight parts of the pipe.

The family forming unit 132 is a component applied to the bend pipe portion and the branch portion, respectively, and is configured to custom design the shapes of the bend pipe family and the branch pipe family.

Figure 6 is a conceptual diagram of a family part according to an embodiment of the present invention. In the case of existing parts, fittings using elbows or tees that are different from or unnecessary from the shape of the branch pipe in the CAD drawing are created, so in the present invention, a curved pipe is formed in a form consistent with the drawing. The shape of the family and branch pipe family is custom designed. To this end, the family forming unit maximizes the straight pipe part through comparison with the extracted bend pipe part and branch part, and the quantity of the bend pipe family and branch pipe family that can be applied in the same shape It can be custom-designed to minimize , or it can be custom-designed by selecting and applying the optimal family parts while pre-fabricating and setting the custom-designed type of bend pipe family and branch pipe family.

The quantity calculation module 140 is used to calculate the quantity for purchasing required piping and piping elements, and includes a quantity calculation unit 141 and a surcharge application unit 142 in detail.

The quantity calculation unit 141 is configured to calculate the quantity information required for each pipe and element in connection with the pipe modeling unit 122 and the family formation unit 132.

Figures 7 to 8 are exemplary diagrams of quantity calculation according to an embodiment of the present invention.

Basically, the data required for quantity calculation are the length and size of the pipe, the number and number of pipes that must be provided for each floor, and the necessary family parts. As mentioned earlier, as the pipe is modeled on the drawing, the length can be easily calculated for straight pipes. This can be done, and in detail, the quantity can be calculated by using the fact that the refrigerant pipe is the same as the liquid pipe/gas pipe and entering the parameters and entering the liquid pipe/gas pipe diameter. In addition, as the standard for piping is usually set, modeling and quantity calculation can be done quickly by creating type parameters and then entering a product with the appropriate pipe diameter.

The premium application unit 142 is configured to generate revised quantity information by applying a set premium rate to the quantity information. In order to correct errors such as defective parts or damage during construction, the quantity required must be calculated with a certain amount of margin rather than being accurately prepared, so the surcharge application unit 142 calculates the quantity in the quantity calculation unit 141. The surcharge rate entered by the user is applied to the quantity information provided. The surcharge rate can be varied depending on the characteristics of the building and construction, and for example, the revised quantity information can be created by adding 5% to the quantity information calculated from the above quantity product department.

The recommendation module 150 is configured in detail to analyze family part creation information as it accumulates through the present invention and recommend family parts suitable for building structures of similar or identical types, that is, bend pipe families and branch pipe families. It is equipped with an information collection unit 151 and a recommendation unit 152.

The information collection unit 151 is configured to collect and cumulatively store family information of bend pipe families and branch pipe families applied to pipe elements for each pipe diameter generated through the pipe modeling unit 122. The family information collected at this time includes summary information and information generated through piping modeling, so that related family information may be recommended when designing a product with high similarity overview information and piping modeling information through deep learning.

The recommendation unit 152 analyzes the family information, derives bend pipe families and branch pipe families with high generation frequency, and recommends them to the family formation unit. Basically, the family parts derived from the present invention replace existing commercial parts and may be already manufactured bend pipe families and branch pipe families, but may also be products that require custom manufacturing. In this case, custom-manufactured family products can be applied to multiple buildings rather than applied once to one building, thereby lowering the production cost and enabling efficient use. Accordingly, the recommendation unit 152 derives bend pipe families and branch pipe families with high generation frequency and recommends them to the family formation unit to increase the production and utilization of previously derived family parts, and the user can apply new family parts or You can select and use family parts with existing production records recommended through the recommendation section.

The parts ordering module 160 is used to manage orders and quotations for the revised quantity and determine economic feasibility, and is comprised in detail of an ordering information management unit 161, a quotation management unit 162, and an economic feasibility analysis unit 163. is provided.

The ordering information management unit 161 generates ordering information for piping elements according to the revised quantity information, first ordering information according to custom production of the bend pipe family and branch pipe family, and second ordering information according to the use of commercial elbow and tee parts. This is a configuration that creates separate ordering information.

As mentioned earlier, the family parts derived from the present invention replace existing commercial parts and may be already manufactured bend pipe families and branch pipe families, but may be products that require custom manufacturing, drawing production and construction. It can significantly improve convenience, but in some cases, it may increase costs compared to using existing products. Accordingly, in order to compare costs, the ordering information management unit 161 generates first ordering information based on custom manufacturing of the bend pipe family and branch pipe family and second ordering information based on the use of commercial elbow and tee parts.

The quotation management unit 162 is configured to collect quotation information for the first ordering information and the second ordering information and generate cost information. In response to the first ordering information and second ordering information, cost information is generated by collecting quotation information from manufacturers that can produce and deliver family parts and companies that supply commercial elbow and tee parts, respectively, and the companies' delivery Negotiation information such as discount rate can also be reflected.

The economic feasibility analysis unit 163 analyzes the cost information and calculates economic feasibility reflecting the input man-hour adjustment rate according to the use of family products and commercial products. Basically, when the cost information is compared and the difference is large, purchases are generally made in the direction of lower costs, but if the difference is less than a set range, the input man-hour adjustment rate according to family products and commercial products is reflected. As mentioned earlier, using family products is advantageous in terms of material savings and efficiency rather than using conventional commercial products, so these differences can be reflected by applying the discount rate set in the cost information according to the first ordering information.

The rights of the present invention are not limited to the embodiments described above but are defined by the claims, and those skilled in the art can make various changes and modifications within the scope of the claims. This is self-evident.
