Description

Automatic discharging method for building pipeline system

Technical Field

The invention relates to the technical field of building industrial production, in particular to an automatic discharging method for a building pipeline system.

Background

A piping system is a system for the transport and distribution of fluid substances. It is widely distributed in buildings and can be classified into wind systems, water systems, etc. according to the difference of fluid substances. The pipeline system belongs to a customized product, each part in each building is designed by a designer according to the actual requirement of the building, and lines and character labels are used as symbols in the drawings to represent information such as types, trends, lengths, intersections and the like of pipelines in the pipeline system.

For a traditional construction process, blanking, processing and installing connection are performed in sequence on a construction site according to information of a pipeline system expressed by a drawing. With the development of the technology, the advantages of mechanical processing are gradually shown, and mainly embodied in efficiency improvement, quality stability, cost reduction and the like. The mechanical processing is to use mechanical and automatic equipment and streamline work to finish the processing and manufacturing of the pipeline system and assemble and install the pipeline system on a using position on site. However, the design drawing cannot be directly used for the mechanized production of the automation equipment, so that the drawing needs to be decomposed and discharged according to a certain rule before the pipeline system is machined, and the drawing is converted into data required by actual mechanized machining.

At present, the mechanical processing of pipelines generally adopts a manual discharging mode to decompose a pipeline system, and the main decomposition flow is that on a computer or a printed drawing, the pipeline system is decomposed into a plurality of sections of standardized straight pipes and pipe fittings according to the required rules of pipeline processing.

However, the inventor of the present invention has found that manual discharge is completely dependent on the experience of the discharging personnel, and for many thousands of components in one drawing, the discharging process needs to be very careful, otherwise the discharging process is very easy to make mistakes. In the discharging process of a pipeline of one system, if a section of error occurs, all the pipelines need to be rearranged, the workload is extremely high, and after the error occurs, a discharging person cannot find the error. After the discharging is finished, the statistics and calculation of the discharging result need to spend the same time as the discharging, and the problems of error, leakage and much are easy to occur because the manual counting is adopted. If the statistical result is checked, the same time is spent for counting one by one again, so that the repeated calculation and counting of a project are realized, and a large amount of manpower and material resources are spent on doing the work. That is, to do this discharge work, the skill requirements of the discharging personnel are very high. In fact, except some professional prefabrication processing plants, professional material discharging personnel are extremely scarce, so that a large number of non-professional material discharging personnel or ordinary workers can discharge materials, and finally, the material discharging result is wrong, so that the problems of construction period delay, economic loss and the like are caused.

In summary, the existing manual discharging method for the pipeline system has the problems of high requirements on discharging personnel, low efficiency, more errors, incapability of reusing data and the like.

The algorithm is mainly compiled according to the standard requirements of design and construction, the size and processing characteristics of raw materials, process requirements, convenience and economy of manufacture and installation, the rules are implemented in a progressive mode, for example, when the decomposition is actually implemented, the A decomposition mode which can be realized is calculated according to the requirements of the design and construction specifications, then the B decomposition mode which meets the requirements is screened from the A decomposition modes according to the size and the processing characteristics of the raw materials, then the one which meets the requirements is screened from the B decomposition modes according to the economy rules, and the implementation of the rules and the selection of the decomposition modes are rapidly and automatically completed by a computer. Therefore, the automatic discharging method provided by the invention has the advantages that the discharging speed is accelerated, and the number of discharging personnel is reduced; the discharging accuracy is improved, and the capability requirement on discharging personnel is reduced; the discharge is more reasonable, and raw materials can be saved; the layout errors are few, the statistical result is accurate, all parties can easily accept the layout errors, the production, processing, installation and construction and settlement transaction branches are less, and the related work progress can be accelerated.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

In the invention, the coordinate position of a line segment in a drawing (such as a CAD plane drawing, a BIM model based on a REVIT platform and the like) and the character marking information corresponding to each line segment are obtained, reading is carried out from a professional perspective, the intention of a designer is reduced, and basic engineering information is constructed, wherein the information comprises the specification and the installation position of a pipeline (such as an air pipe) and the cross information of the pipeline; and then, decomposing the constructed engineering information from the professional perspective of the mechanical processing into a series of members which can be used for actual processing, wherein the members have a series of complete attributes which can be used for actual processing, including pipe section types, specifications, installation positions, materials, processes, system numbers and the like of the pipelines, and regenerating the drawing in the form of member blocks.

The newly generated components all have corresponding identity card Information (ID) and attributes, which also provides convenience for data extraction and statistical calculation.

In a specific implementation mode, a user can construct engineering information according to existing line segments and marking information in a drawing, and can also automatically input size information of the line segments and pipelines to construct the engineering information. When a user decomposes and generates a component which can be used for actual processing on engineering information and extracts data statistics, the user can customize rules, and can generate data which meet various requirements, including generating bar codes and two-dimensional code marks, or generating data which can be read by a database or mainstream production processing equipment which meets rules of data management software. It will be appreciated that the method is also applicable to automatic discharge operations similar to pipe systems, such as bridges, cradles, etc.

Referring to fig. 1 and 2, the invention provides an automatic discharging method for a building pipeline system, which comprises the following steps:

s1, opening a drawing, and performing operations including decomposition, display, hiding, locking and freezing on a layer and a picture block in the drawing so as to identify a pipeline system and extract pipeline and label information;

s3, according to the obtained pipeline segments and the marking information, performing pipeline decomposition according to a set algorithm;

As a specific embodiment, please refer to fig. 1, in step S2, the component type is selected according to the schematic diagram of the software interface, and the pipeline segment and the label information are obtained in the drawing after the operation by using selection and manual input. Specifically, the selection may be performed by using two modes, namely, a click mode and a shortcut key mode, and a corresponding prompt may be given according to the selected component type, for example, the straight pipe section may prompt to click a straight line or a starting point of a straight line, the elbow may prompt to click two straight lines, and the tee may prompt to click three straight lines. In the specific selection process, the selection of the user may not necessarily meet the requirement, for example, the user selects only one straight line but requires the elbow to be generated, or the user selects only one arc line but requires the straight pipe section to be generated. To this end, the present invention employs two methods to control the user's selection: firstly, automatic filtering is carried out in advance, namely if a straight line is required to be selected, a user cannot select an arc line; and secondly, verification is carried out after the selection, namely if two crossed straight lines are required to be selected, but only one straight line or two parallel lines are selected, a prompt is given and the reselection or reselection is required. Meanwhile, in the selected component type, the information such as pipeline line segments, labels and the like in the original drawing is not necessarily complete. In contrast, the input function provided by the invention can be used for supplementing incomplete information in the drawing by a manual input mode which is information input by a user. Therefore, the manual input function and the selection function are seamlessly connected, and the determination can be automatically performed according to the actual operation of the user.

In addition, in the specific implementation, information such as labels in the original drawings is not necessarily standard. Therefore, the invention provides a logic judgment code which can carry out intelligent supplement and intelligent specification, for example, when continuous discharge is carried out, only the pipeline section is selected, and the marking information is not selected, the marking information selected at the previous time is automatically supplemented to the selection, and inquiry prompt is carried out; or if the selected marking information does not accord with the design specification of the common pipeline, the user is reminded to warn and prompts the design specification description, and if the difference is too large to cause that the pipeline cannot be produced, the user is forbidden to warn and is required to reselect or input.

Referring to fig. 1, 2 and 5, in the step S3, the user may use a default algorithm or adjust the algorithm, which is mainly compiled according to the design and construction specification, the size and processing characteristics of the raw material, the process requirements, the convenience and economy of manufacturing and installation, and the rules are implemented in a progressive manner. For example, for the decomposition of the ventilation duct, firstly, the minimum length of the elbow is calculated according to the requirement of the specification on the curvature radius of the elbow of the ventilation duct, and after the minimum length is deducted, the minimum length of the elbow is 500mm according to the specification, and the total length of the pipe section is 3000mm, so that the maximum length of the straight pipe decomposition can be 2500 mm; on the basis, the straight pipe is decomposed according to the used raw materials and the process requirements, if a galvanized steel plate with the width of 1250mm is used, the processing process is common-plate flange connection, and the material length occupied by the common-plate flange is deducted, the length of the straight pipe which can be actually processed can be calculated to be 1160mm, namely 2500mm can be decomposed into 2 sections of 1160mm long standard straight pipes and 1 section of 180mm long straight pipes; however, in view of economy, 1 section of straight pipe with the length of 180mm can generate waste with the length of 980mm, which is not economical, and comprehensive consideration is given, the length of the straight pipe can be increased to 680mm on the basis of meeting the minimum 500mm of the elbow length required by the specification, namely, the final discharge result is 2 sections of standard straight pipe with the length of 1160mm and the elbow with the length of 680mm, which meets the specification and also meets the size requirement of raw materials, meanwhile, because 1 section of straight pipe with the length of 180mm is reduced, a corresponding batch of connecting accessories are reduced, the convenience and the economy of manufacturing and installation are greatly improved, and the discharge is completed.

In the specific implementation, pipeline pipelines and marking information need to be processed, specifically, the method includes the steps of respectively obtaining end points of the pipelines, calculating cross points according to the end points of the pipelines, setting special-shaped pieces at the cross points, judging whether the types of the special-shaped pieces at the cross points are reasonable or not according to the overlapping times of the cross points, decomposing the marking information, calculating the sizes of the special-shaped pieces according to the marking information and the types of the special-shaped pieces, decomposing and calculating the pipelines with the sizes of the special-shaped pieces deducted according to the lengths of standard nodes or non-standard nodes, decomposing the requirements of data by combining with mechanical processing, and storing the decomposed data information in a data file. The result of the decomposition is that various irregular straight lines and marks become members according with specific rules, the members are basic units of production and processing and can be directly used for production line processing and production, and the members are finally assembled on a construction site through auxiliary materials such as connecting bolts and the like.

Referring to fig. 1 and 2, in the step S4, new blocks are generated according to the decomposed data information, the appearance shape, the insertion position, the self-contained property, and the like of the blocks are changed according to the data information, and the newly generated blocks are called as members. The components are basic units of machining products, each component has a unique ID card information ID, the unique ID number divides all thousands of components into different individuals, and the final result of the combination of the components is called a building information model. Meanwhile, in the implementation, all the components have different or same properties, and the same properties organically combine part of the components to form a whole. For example, all the components have the attribute of one system number, and one system number is divided into two parts, namely the system number and the number, so that the components with the same system number are the same, if one of the components is changed, other components with the same system number can be linked, and other components with different system numbers cannot have any influence. Meanwhile, in the present implementation, all the components also have methods capable of performing specific actions, including upgrading, redrawing, reversing, displaying, hiding, etc., for example, the dimensional attributes of the components are changed, which may cause the display appearance of the components to be changed, and the corresponding upgrading method is required to be used for upgrading. In addition, in the implementation, all the components can respond to the external event, all the components are provided with some 'pinch points', and the components can be directly changed by operating the pinch points. For example, the end points of the two ends of the straight pipe section are respectively provided with a stretching pinch point, the straight pipe section can be stretched by clicking the pinch points, the length attribute of the component can be changed at the same time, the label displayed by the component can be changed at the same time if the length of the component is set to be displayed, and the display appearance of the component can be correspondingly upgraded.

It can be seen from the foregoing embodiments that the material discharge operation of the pipeline system only requires the user to select or input some line segments and labels on the drawing according to the prompt, and the invention automatically performs calculation and material discharge. Compared with the existing pipeline decomposing and generating components, the pipeline decomposing and generating components can be completed by a very complicated calculation performed by a professional, but in the embodiment, the pipeline decomposing and generating components can be completed quickly and automatically by a user basically without any operation.

As another specific embodiment, the user may select the required component automatically according to the obtained pipeline and the label information without selecting the component according to the schematic diagram of the software interface, specifically referring to fig. 2, where the step S2 includes: and selecting the layer where the pipeline and the label information are located, and obtaining the pipeline segment and the label information by screening. In this embodiment, the standardization requirement for the drawing is very high, the drawing must strictly distinguish the layers, and accurate labeling, such as the pipeline must be on a drawing alone, the pipeline label must be on a layer alone, or the pipeline label and the pipeline are on the same layer, and each section of pipeline all needs to be labeled at an appropriate distance alone. In the specific implementation process, the method strictly executes the screening action, and screens out the pipeline segments and the labeled information which possibly cause misjudgment. The labels are far away or near from the pipe section, no labels are near the pipe section, the pipe section is too short or too long, the pipe section turns, crosses too much and the like, and all the labels are taken as conditions which can cause misjudgment and are excluded. In actual operation, because the standardization degree of drawings is difficult to guarantee, in the case of full-automatic discharging, due to lack of user participation, wrong discharging, missing discharging and multiple rows are possible to be undetected, so the discharging result can only be used as engineering budget, purchasing stock and the like, and cannot be used as production and processing data. For this, the user can firstly modify the drawing and then acquire the information; or, the user can firstly carry out overall screening and material discharge and then carry out one-by-one inspection and correction.

It can be seen from this embodiment that, a user only needs to execute two actions of opening a drawing and selecting a layer, and the material discharge work of the pipeline system can be automatically completed by one key. However, it should be noted that the user's participation, which is also the process of checking the drawing, is necessary in the case that the drawing is not guaranteed to be completely standard.

As a specific example, the inventors of the present invention have also found through practice that there are sometimes cases where modifications are required for automatic discharge work that has been completed. The discharge of the pipeline system has a characteristic that the change of a certain process or material and the like can cause the discharge of the whole pipeline system to be changed completely. In view of the above, referring to fig. 3, the discharging method provided by the present invention further includes a member modifying step S5, where the member modifying step S5 specifically includes:

s51, selecting the component to be modified and the modification mode of the component. Specifically, the component modification includes single component modification and batch component modification, and most of the single component modification causes the associated other components to be modified adaptively, so that although the attribute of the single component is acquired during modification, the other components associated with the attribute of the component are within the modification range. Meanwhile, in order to conveniently realize modification, the invention provides two modes of entering a modification mode, one mode is that a certain component needing modification is double-clicked, and modification is finished in a popped modification dialog box; the other method is to directly click a pinch point of a component needing to be modified to modify, the pinch point modification can cause other components of the same system number to automatically discharge materials again, but the invention also provides an option for a user whether to cause system linkage.

And S52, modifying the component to be modified and the component having the same attribute with the component to be modified in a linkage manner according to the selected modification mode, and decomposing the pipeline again according to a set algorithm. Specifically, the modified content generated by modifying the dialog box usually includes the algorithm change caused by the change of the process, the material and the like, and the linkage modification deletes all the existing components with common attributes and newly recalculates the decomposition. The linkage modification aims at the components of the same system number connected with the pipe section, when the pipe section of the system is recalculated and decomposed, the components after the pinch point modification are kept fixed, and other components are subjected to relevance adjustment on the basis of the components.

And S53, according to the information data after being decomposed again, linkage regenerating components. Particularly, the batch modification action after the material discharge is finished can still be automatically discharged again in a linkage mode, and the problem of repeated material discharge is avoided.

As a specific example, the inventor of the present invention has found through practice that, for the automatic discharging work that has been completed, the data in the discharging result also needs to be used. In view of fig. 4 and fig. 6, the layout method provided by the present invention further includes a data extracting and automatic statistics step S6, where the data extracting and automatic statistics step S6 specifically includes:

and S61, acquiring the attribute of the selected component according to the set component selection mode. Specifically, in the example, a plurality of component selection modes are set or provided, including all components, user-selected components, component selection according to a system and component screening according to conditions, and the four component selection modes can meet various statistical requirements of users. When extracting, the main attribute information of the member is presented in a statistical window in the form of a member list, and each member in the member list can be checked and rechecked in a drawing. The member entities in the drawing and the statistical list are in one-to-one correspondence through the ID numbers of the members, so that a user can perform position back-check on any member entity in the list in the drawing according to needs, and the user can conveniently and quickly find the member entities or perform corresponding change.

And S62, performing statistical calculation on the acquired component information data according to the set calculation rule. Specifically, a user can perform custom setting on the calculation rule, because the calculation rule is more and more complex, the invention provides three standard calculation rules, including a national quota calculation rule, a market general calculation rule and an internal accounting calculation rule, and the specific statistical calculation is automatically completed according to the three standard calculation rules.

And S63, automatically generating various statistical reports and data files according to the calculation result, specifically generating files in various formats, but generally exporting the files as universal EXCEL files, wherein the exported reports generally comprise component details, production orders, purchase orders, auxiliary material orders and the like, and the exported file formats are forbidden to be modified by default.

In this embodiment, all data are extracted from the optional components in real time, the data extraction and statistical calculation work of the material discharge result can be completed in one key, the professional work occupying a large amount of time in the manual material discharge is completed instantly, the work efficiency is improved, the error probability is reduced, and the data can be reused.

The automatic material discharging method for the building pipeline system provided by the invention can automatically generate the components with the attributes which can be actually produced and processed according to rules only by the starting point and specification information of the pipeline, and the manual material discharging needs to be carried out by the personal understanding of a material discharging person for material discharging and marking, so that the components with the attributes cannot be manufactured. When a certain component is changed, the invention can automatically change the related component and the attribute thereof and automatically discharge again, and manual discharge is only a simple mark without relevance, so that automatic rearrangement cannot be realized. Meanwhile, on the basis of the finished layout modeling work, data extraction and statistical calculation can be automatically completed, all people can accurately count as long as a layout chart and the layout method provided by the invention exist, the manual layout counting and calculation depend on manual counting, the manual calculation is carried out, the process is extremely complicated, and the calculation results of different people in each time can have deviation.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
