Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of point avoidance, and in particular to a point avoidance method for indoor equipment, equipment and medium. BACKGROUND

[0002] Indoor point collision is common in multiple systems due to design sequence relationship. Single system point design cannot consider the impact of subsequent other point positions in advance, resulting in point collision and legend overlap phenomenon in the entire house type.

[0003] For indoor large sample design, in addition to the need to comprehensively adjust the spatial relationship of switches, sockets, lamps and the like, positioning marking of the plane point is also needed. In engineering drawing, indoor point collision and adjustment, plane point positioning marking and the like mainly rely on manual operation of designers. After the designers check the collision point, the point position is moved within the allowable range of rules, and then the positioning is marked. For plane point marking, there are some general plug-ins on the market that can quickly realize positioning marking based on walls, axis networks and the like. However, for indoor point conflict detection and adjustment, it still mainly relies on manual operation. It mainly relies on manual judgment of indoor point conflict and adjustment one by one, which is a large amount of work. The collision check in the vertical direction is often overlooked, resulting in missed detection. Moreover, different designers do not have uniform adjustment rules, and the final drawing expression will also be inconsistent.

[0004] Through the above analysis, the problems and defects of the prior art are as follows:

[0005] The indoor point conflict detection and adjustment in the prior art mainly relies on manual operation. SUMMARY

[0027] To make the objectives, technical solutions, and advantages of the present application clearer, the following will be a clear and complete description of the technical solutions of the present application in combination with the embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] An indoor device point avoidance method, device, and medium are provided in an embodiment of the present application, solving the problem that in the prior art, indoor point conflict detection and adjustment mainly rely on manual operation.

[0029] The technical solutions proposed by the embodiments of the present application will be described in detail in the following in combination with the drawings.

[0030] Figure 1 A flowchart of an indoor device point avoidance method is provided in an embodiment of the present application. As shown in the figure, the indoor device point avoidance method provided in an embodiment of the present application specifically includes the following steps: Figure 1

[0031] Step 10: reading point parameters of components based on a three-dimensional model, the components including ceiling-mounted devices and wall-mounted devices;

[0032] In this step, space and component related information in the Revit model is read according to expression methods, naming, etc. The space includes a house type; the components include lamps, switches, sockets, etc. The information extracted from each space and component core is shown in the following table:

[0033] Table 1 Component Example

[0034]

[0035] Step 20: performing collision detection on the point parameters of the components to determine whether there are colliding components;

[0036] As an optional embodiment, the point parameters of the components are subjected to collision detection to determine whether there are colliding components, which specifically can include: step 201: using three-dimensional Boolean operation to find the intersection between components;

[0037] In this step, it is mainly checked whether the point entities obtained in step 10 are positionally conflicted. The usual detection method can directly calculate the intersection of two Solids according to Boolean operation, and if the result is not empty, it is determined as collision. After detecting the colliding components, the components are moved according to the following rules:​

[0038] Step 202: Perform layered inspection on components arranged in the vertical direction to avoid missing the collision between the upper and lower layers.

[0039] Step 30: If there is a collision component, move the collision component according to the priority rule, which includes the movement order and movement direction, such as Figure 2 As shown;

[0040] As an optional embodiment, moving the collision component according to the priority rule may specifically include: Step 301: for the ceiling device, determining a movement vector according to the direction of the long side of a rectangle inscribed in the room, and moving the collision component to a collision safety distance along the movement vector;

[0041] In this step, if Figure 3 As shown, determine whether there are collisions between points. The priority for point movement is: if a lamp collides with a smoke detector, move the smoke detector and adjust the distance between them to 500mm; if a lamp collides with an exhaust fan, move the exhaust fan and adjust the distance between them to 500mm; if the exhaust fan collides with a smoke detector, move the smoke detector and adjust the distance between them to 500mm. The new coordinate direction is defined by the long and short sides of the largest inscribed rectangle of the bedroom, with the long side as the Y axis and the short side as the X axis. Determine the Y-axis distance of the lamp from the boundary. The greater the distance, the positive direction. This means that if the lamp is not in the center of the room, avoid moving the smoke detector away from the room. The smoke detector's X-axis coordinate is the same as the lamp's X-axis coordinate, and the smoke detector's Y-axis coordinate is the lamp's Y-axis coordinate plus 500mm.

[0042] Step 302: for the wall-mounted device, obtain the empty wall width of the wall where the collision component is located; Step 303: calculate the moving distance of the collision component based on the empty wall width.

[0043] As an optional embodiment, for wall-mounted equipment, obtaining the available empty wall surface of the wall where the collision component is located can specifically include: step 3021: extracting the point parameters of the wall-mounted equipment on the wall where the collision component is located; step 3022: dividing the wall into multiple sub-segments according to the point parameters; step 3023: screening out sub-segments with a spacing greater than the minimum spacing as empty wall surfaces, and the minimum spacing is the width of the current collision component.

[0044] In this step, if Figure 4As shown, the wall where the collision point is located is obtained, the wall surface on this side where the point is located is obtained, and then the position points of all the wall-adjacent point positions on the wall surface are obtained. The wall surface is divided by using the set of position points to obtain a set of empty wall surface line segments. The wall surface that meets the spacing condition can be used to receive the colliding point, for example, the width of the switch is 86 mm. If the spacing between two points is greater than 200 mm, in addition to the width of 86 mm occupied by the two points, the remaining width can also accommodate a complete switch.

[0045] As an optional embodiment, it is judged whether the point positions of the socket, switch, control panel and emergency help button collide. If there is a collision, the first step is to obtain the wall surface where the collision point is located. According to the empty wall surface rule, all the empty wall surfaces of this wall are obtained. The second step is to judge whether the empty wall surface segments on both sides of the collision point are greater than or equal to (200 mm - [collision point spacing]). If yes, the next step is performed. If no, go to the fifth step. The third step is to select the empty wall surface that meets the width requirement (if there are empty wall surfaces that meet the condition on both sides of the collision point, take the empty wall surface with a longer width). The empty wall surface that meets the condition is recorded as w. The fourth step is to move the collision point close to one side of the empty wall surface w. The moving distance is (100 mm - [collision point spacing]). The fifth step is to judge whether the wall where the collision point is located has an empty wall surface with a width greater than or equal to 200 mm (an empty wall surface with a width less than 200 mm cannot be arranged under the collision point). If yes, the next step is continued. If no, search for other walls in the room. Preferably, the wall closer to the collision point is searched first. The fifth step is repeated. The sixth step is to select the empty wall surface closest to the collision point (if the distances are equal, take the empty wall surface with a longer width). The empty wall surface that meets the condition is recorded as w. The seventh step is to move the collision point close to one side of the empty wall surface w. First, the collision point is moved to the end point of the empty wall surface w close to the collision point. Then, the collision point is moved 100 mm in the direction of the empty wall surface w. That is, the moving distance is (100 + [collision point distance from the empty wall surface segment]).

[0046] As an optional embodiment, it is judged whether the video intercom conflicts with other wall points, it is checked whether the height offset value of the video intercom is 1300, if not, the height offset value is modified to 1300, if yes, the first step is continued, the wall surface where the conflict point is located is obtained, according to the empty wall surface rule, all empty wall surfaces of the wall are obtained, the second step is to judge whether the empty wall surface segments on both sides of the conflict point are greater than or equal to (400mm-[the distance between conflict points]), if yes, the next step is continued, if not, it is jumped to the fifth step, the third step is to select the empty wall surface that meets the width requirement (if there are empty wall surfaces that meet the conditions on both sides of the conflict point, the longer empty wall surface is taken), the empty wall surface that meets the condition is recorded as w, the fourth step is to move the conflict point near one side of the empty wall surface w, and the moving distance is (200mm-[the distance between conflict points]), the fifth step is to judge whether the wall where the conflict point is located has an empty wall surface with a width greater than or equal to 400mm (a video intercom point cannot be arranged in an empty wall surface less than 400mm), if yes, the next step is continued, if not, other walls in the room are searched, and the walls closer to the conflict point are preferentially searched, and the fifth step is cycled, the sixth step is to select the empty wall surface closest to the conflict point (if the distances are equal, the longer empty wall surface is taken), the empty wall surface that meets the condition is recorded as w, and the seventh step is to move the conflict point near one side of the empty wall surface w, first to the end point of the empty wall surface w close to the conflict point, and then to the empty wall surface w direction by 200mm, that is, the moving distance is (200+[the distance between the conflict point and the empty wall surface segment]).

[0047] As an optional embodiment, as shown in Figure 5 , there is no empty wall surface that meets the requirements on the wall surface where the conflict point is located, the adjacent wall is searched, the right adjacent wall is closer to the conflict point, the empty wall surface on this wall is searched first, and the right conflict point is first moved to the start point of the empty wall surface, and then moved to the empty wall surface direction by 100mm.

[0048] As an optional embodiment, it is judged whether the equipotential terminal box, indoor distribution box and indoor weak current box collide, if they collide, the processing steps are the same as the video intercom; because of the video intercom, the sizes of the equipotential terminal box, indoor distribution box and indoor weak current box are large, the empty wall surface width judgment, moving distance and switch, socket rules in the rule are different, and there is no difference in other aspects.

[0049] Step 40: Plan view figure overlapping detection is performed on the moved collision component, it is judged whether there is an overlapping figure with the intersection of the bounding boxes of the plan view figures;

[0050] Step 50: If there is an overlapping figure, the overlapping figure is moved according to the wall surface direction and the blank area;

[0051] As an optional embodiment, if there is an overlapping figure, the overlapping figure is moved according to the wall surface direction and the blank area, which can specifically include the following steps: step 501: if the ceiling-mounted equipment has an overlapping figure, the overlapping component is moved to a safe distance according to the priority rule;

[0052] In this step, the legend overlap detection mainly judges whether the bounding box of the point legend has intersection. If so, the following steps are needed to adjust: the lamp and smoke sensing legend overlap, move the smoke sensing, and adjust the distance between the smoke sensing and the lamp to 500 mm; the lamp and exhaust fan legend overlap, move the exhaust fan, and adjust the distance between the exhaust fan and the lamp to 500 mm; the exhaust fan and smoke sensing legend overlap, move the smoke sensing, and adjust the distance between the smoke sensing and the exhaust fan to 500 mm.

[0053] Step 502: If the wall-mounted device has overlapping legends, judge whether the blank width on the left and right sides of the overlapping legend is greater than or equal to the width of the overlapping legend, and collect the distance from the overlapping legend to the midpoint of the wall; Step 503: If it is greater than or equal to the width of the overlapping legend, modify the legend offset parameter according to the blank width, and offset to the midpoint of the wall;

[0054] In this step, as shown in Figure 6 , the first step is to judge whether the blank width on the left and right sides of the overlapping legend is greater than or equal to [the width of the overlapping legend], the second step is to move the point closest to the midpoint of the wall if both satisfy or both do not satisfy, and the third step is to modify the parameter "legend offset left" of the point to be equal to the width of the overlapping legend.

[0055] Step 504: For the overlapping legend of large equipment, adjust the vertical offset parameter according to the installation height, and expand the planar legend spacing to a safe distance along the wall direction. Large equipment includes distribution box and weak current box.

[0056] Step 60: After moving the overlapping legend, position and mark the ceiling-mounted equipment and wall-mounted equipment.

[0057] In this step, as shown in Figure 7 , the wall surface of the building link model is obtained, and then the positions of the indoor box, switch, socket, intercom, emergency rescue button, equipotential terminal box and control panel on each wall surface are obtained. Judge the distance between the point and the two endpoints of the wall, and mark it in the direction of short distance. If there is no other wall point at the endpoint of the wall, mark the distance from the point to the wall endpoint. If there is other point in the middle, mark the two wall points, for example, if the distance is less than 100 mm, no need to mark. Mark the position on the side of the wall where the point is located, for example, mark the distance from the wall 400 mm. If the marking overlaps, move the marking to the other side of the wall.

[0058] No need to mark: the distance between the points is less than 100 mm (the points are close to each other); the distance between the point and the endpoint of the wall is less than 50 mm (the point is close to the wall); the short side is greater than 2000 mm (such as study, bedroom and living room, etc.);

[0059] Lamp marking: First, get the lamp position point, and the lamp family name keyword "lamp". Second, find the closest wall in the perpendicular X and Y directions, and mark the distance between the lamp and the two walls. Third, mark the position to form a closed rectangle with the two walls, and mark the position relative to the rectangle with an outward expansion of 400 mm. Fourth, if the markings overlap, move the markings.

[0060] Smoke detector / fan marking: Get the smoke detector / fan position point, and the smoke detector family name keyword "smoke" and the fan family name keyword "fan". Find the closest lamp, and mark the distance between the smoke detector / fan and the lamp in the X and Y directions (no need to mark if the distance is less than 100 mm).

[0061] Mark the position to form a closed rectangle with the two walls, and mark the position relative to the rectangle with an inward expansion of 400 mm. If the lamp marking is moved inside the rectangle due to avoidance, then the smoke detector / fan marking is moved outside the rectangle with an outward expansion of 400 mm. For rooms with a short side less than 2000 mm (such as bathrooms, balconies, etc.), first, get the lamp position point, and the lamp family name keyword "lamp". Get the smoke detector / fan position point, and the smoke detector family name keyword "smoke" and the fan family name keyword "fan". Second, find the closest wall in the perpendicular X and Y directions, and mark the distance between the ceiling point and the two walls; if there are no other ceiling points at the wall surface, mark the distance between the point and the wall surface, and if there are other ceiling points in between, mark the two ceiling points (no need to mark if the distance is less than 100 mm). Third, mark the position to form a closed rectangle with the two walls, and mark the position relative to the rectangle with an outward expansion of 400 mm. Fourth, if the markings overlap, move the markings.

[0062] As an optional embodiment, the method can further include: detecting the intersection collision relationship between the ceiling-mounted devices and the wall-mounted devices, and decomposing it into a two-by-two collision sub-set; according to the priority rules, solving the sub-sets in turn, and detecting the remaining sub-sets after adjustment; if new collision components are generated after adjustment, reverting to the previous state and marking the conflict area.

[0063] In this step, the intersection collision relationship between the ceiling-mounted devices and the wall-mounted devices is decomposed into a two-by-two collision sub-set, such as the collision between the ceiling-mounted air conditioner and the wall-mounted fire sprinkler. According to the pre-set rules of large volume priority and high maintenance frequency priority, the sub-sets are solved in turn: adjust the position of the low-priority device: move the wall-mounted camera to avoid the ceiling-mounted air duct, and after each adjustment, re-detect the remaining collision sub-sets. If adjustment leads to new collisions, such as the camera blocking the lighting lamp after moving, the system will automatically revert to the state before adjustment, mark the area as a high conflict risk area, and suggest manual intervention or adjustment of the design scheme.

[0064] As an optional embodiment, before reading the point position parameters of the components based on the three-dimensional model, and before the components include ceiling devices and wall-mounted devices, the method can further include: generating an avoidance path probability distribution map of the indoor device through historical installation data training; introducing a safety threshold in the collision detection stage and the planar diagram overlap detection, calculating the minimum avoidance distance and the avoidance order according to the actual use rate of the room; and synchronously processing the avoidance distance and the avoidance order, and the pipeline length by using a multi-objective optimization algorithm, to generate a priority rule and a safety distance.

[0065] In this step, a safety threshold is introduced: the minimum distance between the edge of the device and the pipeline / structural component, and the minimum avoidance distance and the avoidance order are dynamically calculated in combination with the actual use rate of the room. The minimum avoidance distance = basic safety distance × (1 + use rate correction coefficient). The three optimization objectives are: maximum avoidance distance: reducing collision risk; reasonable avoidance order: installing main devices first and then installing branch pipe devices; and minimum pipeline length: reducing material cost and construction difficulty.

[0066] The three objective functions are solved simultaneously by using multi-objective optimization algorithms such as NSGA-II and particle swarm optimization (PSO), to generate a Pareto optimal solution set, from which a scheme that takes into account safety and economy is selected. According to the optimization results, a priority rule for device installation is developed, such as ceiling devices taking priority over wall-mounted devices to avoid pipelines, and large-diameter pipelines taking priority over small-diameter pipelines; and safety distance parameters for each device are output, such as being greater than or equal to 200 mm from the beam bottom and greater than or equal to 150 mm from the wall socket, as the basis for adjusting the point positions of the three-dimensional model.

[0067] As an optional embodiment, the avoidance path probability distribution map of the indoor device is generated through historical installation data training, specifically including: constructing a historical feature matrix, extracting house type topological features and device features, the house type topological features including room length-width ratio, beam column distribution density, and the device features including device volume weight, installation height, and maintenance frequency; and the spatio-temporal correlation of the device features is captured by using a gated recurrent unit to output an avoidance feasibility probability value of each point position parameter.

[0068] In this step, the gated recurrent unit is used to encode the features into a multi-dimensional time sequence vector to capture the spatio-temporal correlation of the device features. The update gate and the reset gate of the GRU retain local features and transmit global features, and the avoidance feasibility probability value of each point position parameter is output through a fully connected layer and a Sigmoid function, with a value in [0, 1], directly reflecting the installation suitability of the point position. The discrete point position probability values are subjected to Kriging interpolation to generate a continuous avoidance path probability distribution map, and the avoidance priority is displayed by using a color gradient to provide an intuitive reference for device installation planning.

[0069] The above is a method embodiment of the present application. Based on the same inventive concept, the embodiments of the present application also provide a point position avoidance device for indoor equipment, which has a structure as shown in Figure 8
