Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Example 1:

Referring to Fig. 1, the present invention discloses a pipeline labeling system based on BIM technology, including:

Building module 1, receives the civil engineering model input from the outside, invokes BIM technology to construct the building information model according to the civil engineering model, saves and outputs the building information model.

The classification module 2, in response to the building information model, picks up all the data marked as pipelines in the building information model to generate a pipeline data group, and divides all the pipeline data groups into multiple proprietary data groups according to the pipeline classification information, including water pipes. For the data group, air duct proprietary data group, bridge frame proprietary data group and other proprietary data groups, the data in the pipeline data group is stored in the corresponding proprietary data group, and all proprietary data groups are stored and output.

Screening module 3, in response to any proprietary data group, judges the proprietary data group, the judgment standard is the pipeline inclination, picks the pipeline data that meets the judgment standard to generate the tilt data group, including the water pipe tilt data group, the air duct tilt data group, Bridge tilt data set and other tilt data sets, output the tilt data set.

The comparison module 4, in response to the building information model, picks up the floor data in the building information model to generate a comparison data set, stores and outputs the comparison data set.

Operation module 5, in response to any inclination data group and control data group, take the two ends and the midpoint of each pipeline in all inclination data groups as the data group to be processed, and call the point selection rules input by the outside world, including the water pipe inclination data Take the median value of the data to be processed for the group, take the minimum value of the data to be processed for the air duct inclination data group, take the minimum value of the data to be processed for the bridge inclination data group, and take the maximum value of the data to be processed for other inclination data groups, according to the point selection rules Pick up corresponding data from each group of data to be processed, generate point information to be processed, call the floor data in the comparison data group and point information to be processed to perform calculations, generate final value data corresponding to the data group to be processed, and output the final value data group. When setting the point selection rules, the operator can choose different rules according to the characteristics of different pipelines. Taking the minimum value for the air duct can facilitate the operator to determine whether the air duct is connected to the floor, whether both ends are not blocked by the floor, etc. Through the analysis, taking the median value of the water pipe can facilitate the operator to observe the overall position of the inclined water pipe, so as to efficiently judge the rationality of the water pipe layout, and taking the minimum value of the bridge frame can facilitate the operator to judge the stability of the bridge frame.

The analysis module 7 receives the actual value data input from the outside, calls the corresponding final value data and the actual value data to perform a difference operation, obtains the error value data, and marks the error value at the corresponding pipeline position of the building information model.

When the operator is carrying out construction, the actual value obtained after the construction is input, and the analysis module 7 can compare the error between the actual value data and the final value data, thereby reminding the operator of the size of the error and facilitating the operator to adjust the situation where the error is large .

The storage module 8, in response to the data group to be processed, the comparison data group and the final value data group, stores the data group to be processed, the comparison data group and the final value data group according to the corresponding relationship.

Example 2:

The invention discloses a pipeline labeling method using a pipeline labeling system based on BIM technology, comprising the following steps:

Build civil models.

Build a building information model based on the civil model.

The building information model is established based on BIM technology, which allows operators to individually select individual elements in the building model for processing and operation.

In the building information model, all the elements marked as pipelines in the building information model are screened out to generate a total collection. In the total collection, the pipelines are divided according to the type of pipelines, and multiple special collections are generated, including the special collection of air ducts, Exclusive collections for plumbing, exclusive collections for bridges, and other exclusive collections.

Air ducts, water pipes and bridges are three important and common types of pipelines. Because the functions of the three pipelines are different, the position considerations in the actual design process are also different. It is convenient for operators to assemble these three pipelines separately Then make a targeted judgment on its characteristics.

Based on the floor in the building information model, judge whether all pipelines are parallel to the floor, and generate horizontal subsets for pipelines parallel to the floor in each exclusive set, and generate inclined subsets for pipelines that are not parallel to the floor, combined For the classification of pipelines in the previous step, the inclined subset includes water pipe inclined subset, wind pipe inclined subset, bridge tray inclined subset and other inclined subsets.

A two-dimensional coordinate system is established with the height of the lowest floor in the building information model as the horizontal axis.

Detect the distance between the pipeline and the lowest floor slab in all horizontal subsets in the building information model, set the scale, convert the measured distance and generate the horizontal focus coordinates.

Because the position of the horizontal pipeline is level with the floor, it only needs to randomly select a point on the horizontal pipeline to calculate the distance between the horizontal pipeline and the floor.

Detect the distance between the highest point, the lowest point, the midpoint of the pipeline and the lowest floor slab in all inclined subsets in the building information model, and generate the pending data for each pipeline according to the scale.

Because different types of pipelines need to select different measurement points to improve the reference value of the final distance information, collecting more measurement points for operators to classify can effectively guarantee the reference value of the information.

According to the type of pipeline, mathematical methods are used to calculate the value of each group of data to be processed. Among them, the operation method for calculating the value of each group of data to be processed in the exclusive collection of air pipes is to take the minimum value, and for water pipes. The calculation method for each group of data to be processed in the collection is to take the median value, and the calculation method for each group of data to be processed in the bridge-specific collection is to take the minimum value. Get the final value coordinates of each set of data to be processed.

The calculation method for each set of data to be processed in the air duct proprietary collection is to take the minimum value to facilitate the operator to analyze whether the air duct is connected to the floor and whether both ends are not blocked by the floor. The calculation method for calculating the value of each group of data to be processed in the exclusive collection of water pipes is to take the median value to facilitate the operator to observe the overall position of the inclined water pipes, so as to efficiently determine the rationality of the water pipe layout. The calculation method for each set of data to be processed in the proprietary collection is to take the minimum value to facilitate the operator to judge the stability of the bridge frame, and to effectively reflect the use of the bridge frame through the distance between the lowest point of the bridge frame and the floor. The stability problems that may exist at the time, reduce the probability of problems such as the bridge position being too high and unstable.

Label all focus coordinates and final value coordinates in a two-dimensional coordinate system.

Detect the distance between each floor and the bottom floor, and convert the vertical axis coordinates of each floor in the two-dimensional coordinate system according to the scale, and mark the vertical axis coordinates of each floor in the two-dimensional coordinate system.

In the two-dimensional coordinate system, draw a reference line parallel to the horizontal axis at the vertical axis coordinates of each floor.

Using the ray method, make a ray perpendicular to the horizontal axis from each focus coordinate point and final value coordinate point to the horizontal axis, and detect each focus coordinate point and final value coordinate point to the first reference line touched by its corresponding ray , mark this distance as the height data for each focus coordinate and final value coordinate.

All height data is generated through scale operations to generate height values.

Mark the height values at the location of each corresponding pipeline in the building information model.

Using the ray method for distance measurement can easily find the floor information corresponding to the pipeline, instead of measuring the distance separately for the pipeline of each floor, which improves the efficiency of the overall calculation and can effectively guarantee the accuracy. Operators can make judgments based on the final height value to see whether the design of the pipeline is reasonable.

Filter different types of pipelines in the civil engineering model, and form civil engineering pipeline collections, including water pipe civil engineering pipeline collections, wind pipe civil engineering pipeline collections, bridge civil engineering pipeline collections and other civil engineering pipeline collections.

Compare the proprietary collection in the building information model with the corresponding civil engineering pipeline collection, filter out pipelines with different categories in the proprietary collection and civil engineering pipeline collection, generate abnormal data, and output the abnormal data to the operator.

Because the civil engineering model is the original data initially constructed, if there is a difference between the pipeline type classification in the building information model and the civil engineering model, it indicates that there is a problem with the pipeline type division, and the operator can make timely adjustments according to the problem.

Round off each height value to an approximate value with 0 at the end of the decimal.

Mark the approximate values at the location of each corresponding pipeline in the building information model.

After the approximate calculation, it can effectively improve the tidiness of the data display on the final building information model, and when multiple data are close to each other, it is also convenient to use the "0" number to distinguish the interval points between different data, reducing the Probability of data read errors.

Example 3:

The invention discloses a pipeline labeling method using a pipeline labeling system based on BIM technology, comprising the following steps:

The construction of each floor slab is carried out according to the building information model.

Read the final value data on the building information model to screen at least three pipelines of each type on each floor for construction.

Measure the distance between the constructed pipeline and the corresponding floor respectively, record this distance as the actual value, and input the actual value into the analysis module 7 .

Read the error value, sum the final value data and the error value to generate the construction value, and carry out the construction of the remaining pipelines according to the construction value.

Errors in actual construction are unavoidable. Therefore, in the early stage of construction, a small number of pipelines are constructed first and the reagent error value of construction is integrated with the final value calculated by design, which can prompt the existence of the error value to the operator and remind the operator Make adjustments in time for large errors.

Read the error value, based on the final value data, the error value threshold boundary is determined and recorded building threshold data.

The calculation of threshold data can effectively retain the error situation of this construction, and play a good guiding role in the next construction. In the subsequent construction, the threshold data can be considered as the reference value of construction error. When selecting data, the Taking this error into account can effectively improve the consistency between the calculated value and the actual construction value, and improve the construction efficiency.

The principle of implementation is: to integrate the method with the system, the operator can use the system to realize efficient calculation of the distance between the pipeline and the floor through several preset data and input of the original model in the design stage, and can realize targeted calculation according to the type of pipeline. Permanent data acquisition, thereby improving design efficiency. In the construction stage, as the construction progresses, the operator can input the actual construction data into the system and integrate it with the data in the system. The system can point out the error value for the operator, so that the operator can Grasp the error value, and ultimately improve the accuracy and efficiency of construction.

The embodiments of this specific implementation mode are all preferred embodiments of the present invention, and do not limit the scope of protection of the present invention accordingly. Therefore: all equivalent changes made according to the structure, shape and principle of the present invention should be covered by the present invention. within the protection scope of the present invention.
