Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
In order to realize the method, the invention firstly redesigns the data structure of the rear end of the existing BIM system, and stratifies and structures the decoration data, so that the method is more suitable for decoration industry.
As shown in fig. 7 and 8, the present embodiment structures the finishing construction data into the following parts: the construction method comprises the following steps of one-layer construction grouping, two-layer construction grouping, three-layer construction article type, a process library, a rated unit price library and construction items. The first-layer construction grouping takes the work type of construction workers as a dimension, and the actual construction items are grouped at the first level so as to meet the management requirements of the system on the construction workers. The construction work in this embodiment includes: electricians, carpenters, tillers, painters, and demolition workers.
The two-layer construction grouping takes a construction object as a dimension and simultaneously describes the operation content (namely, construction content) of workers. The two-layer construction grouping divides the responsibility range of workers, and sets the corresponding relation between each construction object and each model in the existing BIM system front-end entity model library, so that a front-end designer can automatically map the construction object when calling the entity model. For example, on the basis of classification of one layer of construction work, the construction work is further divided into items such as wall masonry, toilet tile laying, stone laying and the like.
The three-layer construction product is a set of two-layer construction contents, and the set is a description of decoration industry standards and decoration construction contents. For each construction product class, the specific attribute and attribute value are provided, and different attributes and attribute values of the construction product class determine different construction processes, different construction materials and corresponding cost or cost. For example, on the basis of a two-layer construction grouping, a set of construction contents meeting the finishing industry standard is obtained, including: napping, waterproofing, paving, leveling, brick joint treatment and the like. Wherein, the construction product class is the item of 'napping', the attribute is 'construction position', and the corresponding attribute value is 'ground' or 'wall surface'; the construction product type paving is characterized by comprising the attributes of paving position, paving method, ceramic tile specification and the like, and the corresponding attribute values are ground or wall surface, tiled or parquet, 600-800 or special shape respectively; the attribute of the construction product type 'brickwork joint processing' is 'processing mode', and the corresponding attribute value is 'pointing' or 'seam beautifying'.
For three-layer construction products, the data maintenance basis is as follows: (1) whether the construction product can be selected or not in a construction project or not is judged, and if the construction product can be selected or not, the construction product needs to be maintained to be concentrated; (2) whether the construction product class has multiple attribute values or not, if so, the construction product class needs to be maintained to be concentrated in the construction product class; (3) whether the construction product category definitely corresponds to the construction object of the two-layer construction grouping or not, and if the construction product category definitely corresponds to the construction object of the two-layer construction grouping, the construction product category needs to be maintained to be concentrated in the construction product category. If a certain construction product class does not meet any one of the above conditions, the construction product class may not be maintained to the construction product class set in order to save the subsequent data maintenance cost.
The process library is a set of construction processes for realizing three layers of construction products, and the construction processes are determined by one of the three layers of construction products, and attributes and attribute values corresponding to the construction products. And coding each construction process in the process library so as to search a certain construction process in the following. For example, the construction process 00001 is: tiling 600 × 600 and 800 × 800 types of ceramic tiles on the ground; the construction process 00002 comprises: the 600 × 600 and 800 × 800 tiles are matched on the ground.
The rated unit price library is a set of preset engineering unit prices, and comprises a material unit price and a labor unit price, and the labor unit price can be set to different values according to different construction types. For example, in the present example, the unit price of cement is set to 10 yuan/0.01 square meter, the unit price of mortar is set to 20 yuan/0.02 square meter, and the unit price of a bricklayer is set to 100 yuan/hour. After a certain construction process in the process library obtains the corresponding unit price in the rated unit price library, the actual engineering cost can be calculated.
A constructor is an instance of a class of constructors that inherits the attributes and attribute values of the class of constructors. When a customer selects a specific construction product class and selects the attribute and attribute value corresponding to the construction product class, the group of data formed by the construction product class and the attribute and attribute value thereof can be called a construction item, which is similar to the construction process, but different from the construction process in that the construction item is a specific application instance. A plurality of construction items can be set under one construction product class. For example, if the client opens three, selects a tile to be tiled, and selects the attribute and the attribute value corresponding to the tile, the generated construction item is: the two construction items can find the corresponding construction process in the process library by the tile with the model of 600 × 600-. And sequencing the construction items generated by all the construction products selected by the customer according to the construction sequence, or sequencing all the construction processes according to the construction sequence to obtain the construction process.
Based on the data architecture, the engineering cost calculation method provided by the embodiment of the invention is shown in fig. 1, and comprises the following steps:
and S101, obtaining a construction product class corresponding to the entity model according to the called entity model when the engineering drawing is drawn.
In this embodiment, obtaining a class of a construction product corresponding to an entity model according to the entity model called when the engineering drawing is drawn includes: and obtaining a construction object corresponding to the entity model according to the entity model called when the engineering drawing is drawn, and then obtaining a construction product class according to the construction object. By combining the data architecture, the construction product acquisition method specifically comprises the following steps:
(1) and obtaining a construction object corresponding to the entity model according to the entity model called when the engineering drawing is drawn. In this embodiment, the solid model corresponds to the construction object one to one. Connecting a front-end drawing tool in the existing BIM system with the data architecture (as the system back end) of the embodiment, as shown in fig. 6, when a designer calls an entity model at the front end to draw an engineering drawing, for example, when the designer drags entity models such as "wall", "tile", etc. onto a canvas of the drawing tool, the back end is automatically mapped to a construction object in a two-layer construction group corresponding to the entity model. Furthermore, parameters such as the specific size of the construction object can be set, so that when the construction object is called, the parameters such as the size of the construction object can be transmitted to the rear end, the rear end obtains the construction area according to the size of the construction object, and the actual usage amount of materials is obtained.
(2) Obtaining construction contents according to the construction objects, wherein one construction object corresponds to a plurality of construction contents;
in this embodiment, according to the two-layer construction grouping in the data architecture of fig. 7, one construction object may correspond to a plurality of construction contents, and a certain construction content corresponding to different construction objects may be the same. For example, when the construction object is a "wall body", the construction contents may be items such as "masonry", "waterproofing", and "paving"; when the construction object is the ground, the construction content can be the projects of building, waterproofing, paving and the like. Since various construction data are layered and structured in advance, after the construction object is obtained, the construction content corresponding to the construction object can be automatically mapped according to the data architecture.
It should be noted that the entity model in this embodiment is a model dragged on drawing software by a front-end user during drawing, and the construction object in this embodiment is a data type in a back-end system (i.e., the data architecture) program, and the types of the data types are different but the expressed contents are the same.
(3) Taking the set of construction contents as a construction article class set;
in this embodiment, since the construction contents corresponding to different construction objects may be the same, when the construction contents in step (2) are collected, the same construction contents should be removed to form a construction content set as a construction article class set.
Through the design of the steps (1) to (3), when the front-end user calls the entity model, the back-end system can automatically map to the construction product class corresponding to the entity model. A plurality of entity models are called by a front-end user, and a plurality of construction product classes can be automatically obtained by a back-end system.
And S102, obtaining a construction process corresponding to the construction product type according to the construction product type and the attribute value of the construction product type transmitted from the user input end.
The set of construction articles obtained in the above steps is transmitted to the housekeeping side in this embodiment, and is shown to the user in the interface of the housekeeping side as shown in fig. 5. Meanwhile, the manager end also stores the attribute and the attribute value of each construction product class. When a user selects a specific construction product class at the manager end and selects the attribute and the attribute value of the construction product class, the manager end transmits the selection data of the user to the back end, and a specific construction process is generated at the back end, wherein the construction process corresponds to the construction product class selected by the user. When the user selects the attributes and the attribute values of a plurality of construction product categories, a plurality of construction processes are correspondingly generated at the rear end.
And S103, acquiring a preset project unit price corresponding to the construction process according to the construction process.
In the data architecture of the embodiment, for each construction process, a corresponding engineering unit price is preset in a quota unit price library, and the corresponding engineering unit price can be directly called in the subsequent engineering cost calculation.
And step S104, calculating the engineering cost of the construction products according to the preset engineering unit price and the pre-acquired engineering quantity.
In this embodiment, the preset engineering unit price includes: the method comprises the steps of presetting material unit price and manpower unit price, wherein different material unit prices are set for different materials, and different manpower unit prices are set for different construction types. The material unit price and the labor unit price are preset and stored in a quota unit price library in the data architecture of fig. 7. The pre-acquired engineering quantity comprises pre-acquired material usage and pre-acquired construction working hours, wherein the material usage can be acquired through user input, and can also be acquired in a manner of transmitting entity model parameters when a designer calls a front-end entity model; the construction man-hours are acquired in advance by user input. The embodiment of calculating the engineering cost of a certain construction product specifically includes:
(1) calculating the material cost of the construction products according to the preset material unit price and the pre-acquired material usage amount; specifically, in the data structure of this embodiment, a specific construction process is associated to a predetermined unit price for the material used in the construction process in the rated unit price library from the process library to the rated unit price library, and then the product of the unit price of the material and the usage amount of the material is calculated according to the actual usage amount of the material, so as to obtain the material cost of the construction product.
(2) Calculating the labor cost of the construction products according to the preset labor unit price and the construction working hours acquired in advance; and calculating the product of the construction working hours and the labor unit price to obtain the labor cost of a certain construction product.
When the called entity model has a plurality of entity models, namely the construction product classes, the total engineering cost is the sum of the engineering costs of all the construction product classes. Therefore, as shown in fig. 2, the method according to this embodiment further includes:
and step S105, summarizing the engineering cost of all the construction products to obtain the total engineering cost.
In this embodiment, when the preset unit price of the engineering includes the preset unit price of the material and the preset unit price of the labor, the engineering costs of all the construction articles are collected, which includes: and summarizing the material cost and the labor cost of all the construction products to obtain the total engineering cost.
In order to further improve convenience and efficiency of the engineering computation amount in this embodiment, this embodiment further includes: acquiring the construction work type of the construction product according to the construction process corresponding to the construction product; the mobile terminal corresponding to the construction work type of the construction product is dispatched; and scheduling the operation time of the construction work types of the construction products after receiving the order receiving feedback of the mobile terminal.

The constructor performs order receiving operation on the mobile phone according to the actual situation of the constructor, and the mobile phone feeds back the order receiving result to the system architecture (namely, the rear end of the system) of the embodiment. And the rear end schedules the operation time of workers according to the order receiving feedback. Further, as shown in fig. 6, a special scheduling system may be further provided in this embodiment for automatically scheduling the working time of the construction worker.
