For convenience of understanding, a detailed flow of an embodiment of the present invention is described below, and referring to fig. 1, a first embodiment of a method for labeling a horizontal component based on a BIM platform according to an embodiment of the present invention includes:

101. loading a structural plan view on the BIM platform;

it is to be understood that the execution subject of the present invention may be a horizontal component marking device based on a BIM platform, and may also be a terminal or a server, which is not limited herein. The embodiment of the present invention is described by taking a server as an execution subject.

In this embodiment, before the auxiliary labeling device is executed to automatically label the horizontal member, a structural plan view at least including the horizontal member is constructed in advance, and specifically, the structural plan view may include a shaft network, a structural beam, a floor slab opening, a floating plate, and other structural members. Here, only structural members satisfying preset conditions are labeled, such as horizontal members, borderless superposition with the axle network, and the like.

Specifically, the structural plane view can be drawn in the BIM software Revit, or can be drawn and imported through other non-BIM software, and after format processing, the structural plane view can meet the attribute requirements of the auxiliary labeling device on the component.

102. Starting the auxiliary marking device, identifying each horizontal component and each axis network in the structural plane view, and screening a plurality of component marking objects from each horizontal component on the basis of the axis networks;

in this embodiment, after the structural plan view is loaded on the BIM platform, the front-end button where the auxiliary labeling device is located is clicked, so that the automatic labeling function of the horizontal component can be entered. Taking the shaft net as a screening condition, searching a horizontal component meeting the screening condition by referring to the axis of the shaft net and the auxiliary positioning line, and taking the horizontal component as a component labeling object to perform subsequent labeling on the component labeling object.

Specifically, as for the horizontal component on the axis of the shaft net and the auxiliary positioning line, the horizontal component can be fixedly arranged or changed into a marking position for the horizontal component according to the axis position of the shaft net, and automatic marking is carried out, the screening conditions can be preset here: and the marking operation is not required to be carried out on the horizontal component with the key lines such as the side line or the central line and the central axis of the shaft network superposed. When the object is marked by the screening component, the object is determined by judging whether the side line or the central line of each horizontal component is coincident with the axis of the shaft network.

In addition, the user also selects the component type, drawing range and the like to be labeled on the control interface to screen the component labeling objects needing to be labeled in the horizontal components. Specifically, the type of the component to be marked can be determined through a pointing interface in Revit, and the component area range to be marked can be selected and determined by using a selection box in a structural plane view.

103. Determining at least two pieces of marking position information corresponding to each component marking object according to the component type of each component marking object, and identifying a continuous marking relation between the component marking objects according to the marking position information;

in this embodiment, the component type of the component marking object may include: beam members, plate members, wherein the beam members may comprise end beams, shaftless beams, axis beams, positioning lines, etc., and the plate members may comprise lowering plates, cantilever plates, plate openings, etc. The component marking objects of different component types have different marking positions, and when the component marking objects are marked, the component marking objects are mainly applied to marking lines and marking reference lines for assisting in marking execution, so that the marking position information determined at least comprises position information of the marking lines and the auxiliary marking lines.

Specifically, the position information of the marking line and the auxiliary marking line of each component marking object is determined according to the component type. For example, for a beam member, according to different types of beam members, the corresponding end point and side end can be selected as position information of a marking line, and an axis or an auxiliary positioning line near or having an association relationship can be selected as a position of the marking reference line. For example, for the plate members, the positions of the marking lines and the positions of the marking reference lines are determined by selecting boundaries among the plate members or the beam members according to different types of plate members.

In this embodiment, through the line relation between different marking position information, the connection marking relation between each component marking object can be identified and obtained, including the existence of the connection marking relation and the absence of the connection marking relation, and the component identification objects with the connection marking relation are classified into the same connection marking relation group to represent the continuous marking relation of each constructed marking object, so that the continuous marking of uniform specification can be sequentially performed subsequently, and the marking efficiency is improved.

104. Labeling each component labeling object according to the continuous labeling relation to obtain component labeling information, and performing abnormity detection on the component labeling information to obtain a detection result;

in this embodiment, after the continuous labeling relationship of each component labeling object is determined, the component labeling objects are labeled by using the characterized continuous labeling groups as units, and the same group of continuous labeling groups can label the labeling pattern of one component labeling object by means of shearing extension, and then label other component labeling objects by applying the labeling pattern, so that each group of continuous labeling groups labels the component labeling objects.

In this embodiment, after the preliminary component marking information is generated, the local marking content may have the problems of overlapping marking, redundant marking, repeated marking, mutual influence of marking, and the like. The preliminarily generated component labeling information can be optimized aiming at different types of labeling abnormity problems through labeling abnormity detection results (namely, labeling overlapping, redundant labeling, labeling repetition, labeling mutual influence and the like).

105. And optimizing the component marking information according to the detection result, and adding the optimized component marking information to the structural plane view.

In this embodiment, according to the detection result of the component labeling information abnormality, the corresponding optimization strategy is used to optimize each abnormal labeling content by combining the construction type, the labeling position, the labeling distance, and the like of the component labeling information abnormality. The method specifically comprises the steps of adjusting the distance of the marked lead, deleting marked contents, combining similar marked contents and other optimization strategies, optimizing abnormal marked contents and realizing unified arrangement of marks. And finally, marking the horizontal component on a structural plane view and then drawing the horizontal component to finish, thus obtaining a corresponding structural design drawing.

In the embodiment of the invention, all horizontal components needing to be marked in a project can be marked at one time, and one or more horizontal components can be marked according to custom configuration; and various abnormal labeling problems occurring in the labeling process are optimized, and component labeling information is adapted according to the plotting requirements so as to be added into a structural plane view, so that the plotting quality and efficiency are obviously improved. The automatic labeling of different types of horizontal components is realized, and the labeling efficiency and accuracy are improved.

Referring to fig. 2, a second embodiment of a method for labeling a horizontal component based on a BIM platform according to the present invention includes:

201. loading a structural plan view on the BIM platform;

202. starting the auxiliary marking device, identifying each horizontal component and the shaft network in the structural plane view, identifying contour lines corresponding to each horizontal component, and determining the position relation between each contour line and each axis in the shaft network;

203. determining the association relationship between each horizontal component and the axle network according to the position relationship, and screening component labeling objects from each horizontal component according to the association relationship;

in this embodiment, the preset components to be labeled include all horizontal components which are not directly connected with the large axis, including beam components, plate components, hole components, floating plate components and other types of components, and the horizontal components which are directly connected with the axle network can directly label position conversion, so that subsequent labeling operation is not required. Wherein direct connection to the major axis means that the side or centerline of the horizontal member is collinear with the axis.

Specifically, the relationship with the large axis is used for representing the relationship between the horizontal component and the axle network, each horizontal component contour is identified, the side line or the center line of the corresponding horizontal component is determined, the coincidence detection is carried out on each axis of the axle network, whether each horizontal component is in relationship with the large axis is determined, if the horizontal component contour coincides with the large axis, the relationship of the horizontal component is determined to be in relationship with the large axis, and otherwise, the relationship of the horizontal component is determined to be not in relationship with the large axis. And using the horizontal component with the connection with the large axis as a component marking object.

In addition, due to the positioning of the wire members, when the designer builds a plan view of the structure, additional axes for assisting positioning are added, and these axes do not have a direct positional relationship with the large axis, and also need to be positioned in a labeling manner, that is, the axes are used as the member labeling objects.

204. Determining the marking line position of each component marking object according to the component type of each component marking object;

205. identifying a marking reference line corresponding to each component marking, and determining the position of the marking reference line of each marking reference line according to the component type of each component marking object;

206. generating marking position information corresponding to each component marking object according to the marking line position and the marking reference line position, and identifying continuous marking relations among the component marking objects according to the marking position information;

in this embodiment, according to the component type of each component marking object, the auxiliary marking device may determine the marking line position according to different component types, that is, the marking line positions of the auxiliary marking objects of different component types are different.

Wherein the component types include beam structures and plate structures, specific examples are as follows: end beam member: one end of the beam member is not connected with a vertical member or a horizontal member, and both sides of the beam member are not provided with connecting plate members, and the position of the tail end of the beam member is not collinear with the major axis and the beam positioning line; no axis beam: in the beam width range of the beam-like member, an axis parallel to the central line does not exist, and the side edge line is not collinear with the vertical member edge line; an axis beam: an axis parallel to the center line exists in the beam width range of the beam-like member, but is not collinear with the side edge line or the center line; positioning the wire beam: the beam width range of the beam-like member has a positioning line parallel to the central line, but is not collinear with the side line or the central line of the beam; the plate component mainly comprises a descending plate (two plates with height difference), a cantilever plate and a plate hole.

Specifically, for component marking objects of different component types, the corresponding marking line positions may be as follows:

A. end beam, marking line position is at the end of beam component;

B. an axis-free beam, if the beam member is connected to the web member on one side and not on the other side, the position of the marked line is on the side without the web member; if both sides of the beam member are connected with the plate members or both sides are not connected with the plate members, selecting any one side as the position of the marking line;

C. the axis beam and the positioning line beam are arranged on two sides of the beam component.

D. And lowering the plate, wherein the marking line is positioned at the position which is not overlapped with the beam member and is at the intersection line between the plates with different elevations.

E. And the marking line is positioned on the boundary of the hole which is not flush with the vertical member or the beam member.

F. And the marking line of the float plate is positioned on the boundary of the sideline which is not overlapped with other components, namely the overhanging side.

In addition, the marking reference line is an object for component marking reference, and specifically refers to an axis and a positioning line parallel to the marking line. In the marking content of a component marking object, the starting point of a marking lead is on a marking line, and the end point of the marking lead falls on a marking reference line. Wherein, different component types and their corresponding labeled reference line examples can be as follows:

and the positioning line marks the position of the large axis parallel to the reference line.

The axis beam, the positioning line beam, the marking reference line is the axis or the positioning line passing through the beam width range.

The reference line is the closest axis to the beam, although the beam is identified as being parallel to the line.

The marking reference line is an axis or a positioning line parallel to the marking line.

The plate falls, no axis roof beam, and the mark reference line is the axis or the location line parallel with the mark line.

In addition, after the position of the marking line and the position of the marking reference line are determined, continuous marking is carried out according to the relation between the position of the marking line and the position of the marking reference line, so that the marking efficiency is improved. The details are as follows:

1) Drawing a perpendicular line between a marking line corresponding to each component marking object and a marking reference line according to the marking position information;

2) Continuously labeling and grouping the labeling lines and the labeling reference lines according to the vertical relation between the labeling lines and the labeling reference lines and the vertical lines respectively to obtain a grouping result;

3) And determining the continuous labeling relation among the component labeling objects according to the grouping result.

In this embodiment, according to the position of the marking line and the position of the marking reference line determined above, the continuous marking relationship between the marking objects of the components is determined through various conditions from the starting point of the marking line to the perpendicular line of the marking reference line. Wherein, for the different types of marking lines and their corresponding continuous marking groups, the following examples can be given:

and the positioning lines are perpendicular lines towards the two sides of the positioning lines at the two end points and the middle point, stop when extending to the marking reference lines, and all the positioning lines which are intersected with the perpendicular lines and perpendicular to the perpendicular lines and the marking reference lines at the two sides are grouped into the same continuous marking group.

And selecting a marking line, making vertical lines in the directions of two end points and the middle point of the marking line towards two sides of the positioning line, stopping when the marking line extends to the marking reference line, and grouping all the marking lines of the same object, which are intersected with the vertical lines and are vertical to the vertical lines, and the marking reference lines at two sides into the same continuous marking group.

The plates and the shaftless beam are selected, one marking line is selected, perpendicular lines are made in the two end points and the middle point of the marking line in the directions of the two sides of the positioning line, the marking line stops when the marking line extends to the marking reference line, and all the plates, the marking lines of the shaftless beam and the marking reference lines on the two sides, which are intersected with the perpendicular lines and perpendicular to the perpendicular lines, are grouped into the same continuous marking group.

The marking lines and the marking reference lines on the two sides of the axis beam and the positioning line beam are grouped into a group of continuous marking groups, and the marking lines and the marking reference lines of the end beam are in the same group of continuous marking relations.

207. According to the continuous labeling relation, continuously labeling the component labeling objects corresponding to the same continuous labeling group respectively to obtain first labeling information;

208. determining component marking objects of the same type in the same continuous marking group;

209. calculating the labeling distance between adjacent component labeling objects of the same type and the labeling distance of each adjacent component labeling object of the same type, judging whether the labeling distance is smaller than a preset distance threshold value, and judging whether each labeling distance is the same in a crossed manner;

210. if the labeling distance smaller than the preset distance threshold value and the same labeling distance exist, second labeling information is generated for adjacent component labeling objects smaller than the preset distance threshold value and the same labeling distance, the first labeling information is adjusted based on the second labeling information to obtain component labeling information, abnormal detection is carried out on the component labeling information, and a detection result is obtained;

in this embodiment, continuous labeling is performed on component label objects in the same continuous label group, for example, the same component label object is located on the same vertical plane of the structural plane view and has only different horizontal dimensions, so when labeling the component label object, the labeled content can be located on the same horizontal plane, and a labeled distance range is defined according to the horizontal length of different component label objects, and the labeled distance is written into the labeled object at the same time.

In addition, continuous labeling is realized on the components belonging to the same continuous labeling groups, the labeling of the labeling objects of the components of the same type is optimized, and only one group of labels is generated on the components of the same type with the same labeling distance and smaller intervals.

In addition, for the automatic generation of the preliminary component marking information, the detection of marking abnormity can be performed, so that the accuracy of horizontal component marking is improved. The specific execution flow is as follows:

1) Judging whether the labeling contents of each component labeling object in the component labeling information are overlapped or not;

2) If the marked contents are overlapped, determining a first abnormal marking category corresponding to each overlapped marked content according to the continuous marking group where each overlapped marked content is located, the corresponding component type and the corresponding marking position;

3) If the labeling content does not overlap, judging the labeling distance corresponding to each labeling content which does not overlap, and determining a second abnormal labeling category corresponding to each labeling content which does not overlap according to the labeling distance;

4) And obtaining a detection result based on the first abnormal labeling type and the second abnormal labeling type.

In this embodiment, in the component labeling process, the labeling contents of different component labeling objects are prone to overlap, and here, the abnormal labeling type is determined by combining the characteristics of each component labeling object, including the determined component type and the labeling position. The influence factors of the method are continuously marked with groups, component types, marked positions and marked distances, and the judgment process of the second abnormal marked type is specifically as follows:

first anomaly annotation class a: two different continuous labeling grouping internal component labeling objects, wherein the dimension lines of the labeling contents are mutually parallel and mutually overlapped;

first anomaly annotation class B: marking objects of the components corresponding to the hole, the floating plate, the descending plate and the shaftless beam, wherein marking contents of which the marking lines on the outermost edges are connected with the marking reference lines are not parallel to and mutually overlapped with dimension lines of other marking contents of the continuous marking groups;

first anomaly annotation category C: the same group of continuous labeling groups only have two continuous labeling contents, the labeling contents are overlapped, and the labeling distance is less than 400mm;

first anomaly annotation category D: the same group of continuous labeling groups have more than two continuous labeling contents, the labeling contents on the extreme edges are overlapped, and the labeling distance is less than 400mm;

first anomaly annotation category E: for the first abnormal labeling type D, the rest labeling contents are overlapped;

a second anomaly annotation category F: marking objects of the components corresponding to the hole, the floating plate, the descending plate and the shaftless beam, wherein the marking distance between a marking line of marking contents and a marking reference line is greater than 1/2 of the distance between the two marking reference lines;

second anomaly labeling category G: and marking the object by the component with the distance less than 1m, wherein the marking reference lines of the marked content are the same, and the lead end points are on the same marking reference line and have the same marking distance.

211. If the detection result is a first abnormal labeling type, matching an optimization strategy corresponding to the first abnormal labeling type, and performing labeling lead optimization on the overlapped labeling contents;

212. and if the detection result is a second abnormal labeling type, rejecting the labeling content of which the labeling distance does not meet the preset labeling size condition, and adding the optimized component labeling information to the structural plane view.

In this embodiment, after various situations of abnormal annotation existing in the annotation information are detected, the corresponding optimization strategy is executed according to whether the detection result is the first abnormal annotation category or the second abnormal annotation category. Optimizing the marking lead line aiming at the overlapped marking content, and adjusting the horizontal position of the marking content; and rejecting the marked contents with abnormal marking distance. The detection result and the corresponding executed optimization strategy are specifically as follows:

first anomaly annotation category a: adjusting the distance from the dimension line to the starting point of the marking lead line so as to prevent the marked contents from overlapping;
