When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application.

Fig. 1 is a schematic view of an application scenario in an embodiment of the present application, as shown in fig. 1, a building drawing is often stored in a core terminal 102, where the core terminal 102 is connected to a plurality of local terminals 104 (such as a computer, a mobile phone, a tablet computer, etc.) through a network, when a user needs to refer to the building drawing at the local terminal 104 on the user side, the local terminal 104 needs to initiate a building drawing acquisition request to the core terminal 102 through the network (such as a local area network or a wide area network), so that the core terminal 102 sends relevant data of the building drawing to the local terminal 104, and the local terminal 104 performs rendering and displaying of the building drawing.
Because the building drawing includes data of multiple dimensions of the building, such as electrical data, construction data, component data and the like, the volume of the data is large, so that when the local terminal 104 renders the building drawing, a large amount of processing resources are required to be occupied, the phenomenon of blocking of the local terminal 104 is caused, even the rendering of the building drawing fails, and a user cannot refer to the building drawing.
The application provides a display method of a building drawing, which aims to solve the technical problems in the prior art. The main conception of the display of the building drawing is as follows: the method comprises the steps that a plurality of layers are preset for the building drawing, each layer comprises display data of the building drawing in a corresponding proportion, when a user triggers a drawing display instruction, a target layer of the building drawing to be rendered and displayed is determined based on the determined display proportion, so that only pictures corresponding to the target layer are required to be rendered, the data quantity required to be processed by the local terminal 104 is reduced to a large extent, the fluency of the display of the building drawing is improved, and meanwhile, the core terminal 102 only needs to send the target layer in the form of the pictures to the local terminal 104, and the safety of the building drawing is improved.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flow chart of displaying a building drawing according to an embodiment of the present application, where the method may be performed by any device having a data processing function and a display function, such as the local terminal 104 described above, or a display device in a subsequent embodiment.
As shown in fig. 2, the method for displaying the construction drawing includes:
step S201, according to a drawing display instruction triggered by a user, determining a display proportion.
The drawing display instruction may be an instruction for opening a building drawing or a zoom instruction for a currently displayed building drawing. The user can trigger the drawing display instruction by inputting the instruction into user equipment, such as a mobile terminal. Such as by inputting gesture instructions through a touch screen, inputting instructions through a mouse, keyboard, etc. input devices. The display scale may be expressed in terms of percentages, decimal numbers, etc., such as 110%, 1.5, etc.
In one embodiment, the user may trigger the drawing display instruction through a voice instruction including a preset keyword.
In one embodiment, the drawing display instruction may be a drawing scaling instruction, such as a drawing enlarging instruction and a drawing shrinking instruction, and the user may trigger the drawing scaling instruction through a scaling operation, where the display scale may be a scaling scale corresponding to the scaling instruction.
The zoom operation may be a double click operation, a double finger operation, a mouse sliding operation, a long press operation, an input operation, or the like.
When a scale is included in the scaling operation, a display scale is determined based on the scale. When the zoom operation does not include a zoom scale, the display scale may be determined based on parameters such as the number of zoom operations, operation time, gesture trajectory, and the like.
Illustratively, taking a two-finger operation as an example, the display scale may be determined by the distance between the two fingers, with the larger the distance, the larger the display scale. For example, when the number of double-click operations is increased once, the display scale is increased by a set step length, such as 0.1, 0.2, etc., based on the original scale.
In one embodiment, the user may trigger the drawing display instruction by opening a corresponding program for displaying the drawing or clicking a preset link.
Specifically, when the user triggers the drawing display instruction or receives the drawing display instruction, the display proportion of the current display interface of the user equipment is determined, wherein the display proportion can be a default proportion or a common proportion corresponding to the user.
In one embodiment, the display proportion may be determined according to a drawing display instruction triggered by a user and a user identifier corresponding to the drawing display instruction. For example, the current display proportion can be determined based on the corresponding relation between the user identifier, the drawing display instruction and the display proportion, and the currently triggered drawing display instruction and the user identifier triggering the drawing display instruction, so that the determined display proportion can be different when different users trigger the same drawing display instruction.
In one embodiment, a corresponding relationship among a user identifier, a drawing display instruction and a display proportion of the user can be established according to a historical operation record of the user.
For example, when the user u1 and the user u2 perform zoom control of the building drawing by using the same gesture instruction (such as a double-finger zoom instruction), the display ratio corresponding to the user u1 may be 1.5, and the display ratio corresponding to the user u2 may be 1.6.
And step S202, determining a target layer of the building drawing according to the display proportion.
The building drawing comprises a plurality of preset layers, and each layer comprises display data in a corresponding display proportion.
In one embodiment, the layer may include display data for one or more areas of the construction drawing.
In one embodiment, the layers of the construction drawing may be divided according to profession, so that different work types may correspond to different layers.
By way of example, the layers of the construction drawing may include component layers, label layers, power layers, fire layers, heating and ventilation layers, water supply and drainage layers, and the like.
In one embodiment, a display scale may correspond to one or more layers.
In one embodiment, the target layer of the building drawing may be determined according to a pre-established first correspondence and the determined display scale. The first corresponding relation is used for describing the corresponding relation between each display proportion and the layer of the building drawing.
In one embodiment, different users may correspond to different first corresponding relationships, and the first corresponding relationship corresponding to the user may be obtained based on a user identifier of a current login user or a user identifier corresponding to a drawing display instruction, so as to determine a target layer of the building drawing based on the first relationship corresponding to the user and the determined display proportion.
In one embodiment, when designing a building drawing, multiple layers may be set for the building drawing according to requirements, and a scale attribute, such as a visible scale range, may be added to each layer, and then, based on the determined display scale and the scale attribute, the layers of the building drawing may be screened, so as to determine one or more target layers corresponding to the display scale.
For example, layers 1-10 may be set to correspond to a display scale of 100% and layers 11-20 may correspond to a display scale of 120% by a scale attribute. Layer 1 may also be set to correspond to a display scale of 100% by a scale attribute, and layer 2 may correspond to a display scale of 110%.
In one embodiment, taking a drawing display instruction triggered by a user as an example of a drawing scaling instruction, the user triggers the drawing scaling instruction by inputting a scaling operation, and during the period of inputting the scaling instruction by the user, a dynamic display layer of the building drawing can be determined based on the display proportion corresponding to each time node, and the dynamic display layer is rendered and displayed by the corresponding time node, so that the response speed of controlling the building drawing is improved, and the dynamic effect of drawing scaling display is improved.
Wherein, the interval between adjacent time nodes can be 0.1s, 0.2s or other time intervals.
In one embodiment, for each time node, the dynamic display layer corresponding to the time node may be determined according to the display proportion of the time node, and the specific manner is similar to that of step S202, and only the target layer is replaced by the dynamic display layer, which is not described herein.
Step S203, rendering and displaying the target layer.
Specifically, after determining the target layer, the user equipment sends the number of the target layer to the core terminal, the core terminal sends the target layer to the user equipment, and the user equipment renders the target layer to display the display data corresponding to the target layer.
In one embodiment, after determining the target layer, the associated layer of the target layer may be determined based on the layer association relationship of the building drawing, and the target layer and its associated layer may be rendered and displayed. The above-mentioned association relationship may be determined based on the association attribute of the layer.
In one embodiment, the above-described association attributes may be added for each layer when the layers of the building drawing are set.
According to the display method of the building drawing, a plurality of layers are preset for the building drawing aiming at the scene of building drawing display at the local side or the user side, different layers comprise different display data of the building drawing, and the layers and the display proportion have corresponding relations, when a drawing display instruction triggered by the user is detected, the target layer of the building drawing to be rendered and displayed is determined based on the display proportion corresponding to the drawing display instruction, so that when the building drawing is rendered, all drawing data are not required to be rendered, only the target layer of the building drawing is required to be rendered and displayed, compared with the situation that the complete building drawing is directly rendered, the magnitude of the rendered data is reduced, the limitation on equipment hardware is reduced, the smoothness and the speed of displaying the building drawing are improved, meanwhile, the safety of the building drawing is improved by only interacting partial layers, the local side terminal is enabled not to be required to store the building drawing in advance, and the memory occupation of the local terminal is reduced.
In one embodiment, the target layer may also be determined in consideration of the user identification, i.e., based on the user identification and the user-triggered drawing display instructions. The user identification is the user identification corresponding to the drawing display instruction or the user identification triggering the drawing display instruction user.
In one embodiment, determining a target layer of a building drawing includes:
acquiring performance parameters of user equipment; and determining the target layer according to the display proportion and the performance parameter.
The user equipment is equipment for displaying the building drawing on the local side or the user side, and the user can trigger the drawing display instruction through the user equipment, such as inputting a zoom instruction on the user equipment. The performance parameters of the user device may include parameters of a central processing unit (CPU, central Processing Unit) and an image processor (GPU, graphics Processing Unit) of the user device.
Specifically, the layers of the building drawing can be screened based on the display proportion, so as to obtain a plurality of layers corresponding to the display proportion, and further, based on the performance parameters of the user equipment, the target layer which is finally rendered and displayed is determined from the plurality of layers corresponding to the display proportion.
In one embodiment, an upper limit number of layers that can be rendered at a time may be determined based on a performance parameter of the user device, and based on the upper limit number, when the number of layers corresponding to the display scale is greater than the upper limit number, the upper limit number of layers may be determined from the plurality of layers corresponding to the display scale to be each target layer.
The target layer is determined by combining the performance parameters of the user equipment, so that the phenomenon that the user equipment is blocked due to the fact that the number of target layers to be rendered is large or the display data is large is avoided, and the fluency of drawing rendering is further improved.
Fig. 3 is a schematic flow chart of a display of a building drawing according to another embodiment of the present application, as shown in fig. 3, in this embodiment, based on the embodiment shown in fig. 2, steps S202 and S203 are further refined, and steps of determining an interest layer and obtaining a drawing display instruction are added before step S201, and as shown in fig. 3, the display of a building drawing according to this embodiment may include the following steps:
step S301, determining an interest layer of the user according to the viewing history of the user.
The user may be a user who logs in currently, such as a user who logs in to a user device, or a user who logs in to an application, applet, web page, etc. that displays the building drawing.

In one embodiment, the user's viewing history may be determined from a viewing record of the building drawing based on the user identification.
In one embodiment, the user identification of the currently logged-in user may be determined based on login information, such as login information of the user device or login information of an application, applet, or web page corresponding to the building drawing.
For example, a user, such as a person in charge of a subcontracting construction unit, may input login information in a user device (a device provided at the construction unit) to log in the user device, and refer to a building drawing based on a preset application installed on the user device.
For example, a user, such as an architect, may refer to a building drawing by logging in a preset applet on the mobile terminal to perform construction based on the building drawing. The user identification of the user may be determined based on the login information in the applet.
Step S302, displaying the interest layer and acquiring a drawing display instruction triggered by a user on the interest layer.
In one embodiment, the user device may cache each layer of the building drawing that was referred to at a historical time, and after determining the interest layer, may look up the interest layer from the user device's cache and display the interest layer. The user can trigger the drawing display instruction, such as a drawing scaling instruction, on the interface for displaying the interest layer.
In one embodiment, after the interest layer is determined, the interest layer may be obtained from the core terminal and displayed by default when the user clicks on the building drawing. And the user can trigger drawing display instructions on the interest layer, such as drawing scaling instructions input.
In one embodiment, the interest layer may be displayed by default during the period when the user triggers the drawing display instruction, such as the period when a drawing zoom instruction is input, until the drawing zoom instruction is input or until a target layer is determined.
Through the display of the interest layer, the step that a user triggers or issues a drawing display instruction to consult the interest layer can be omitted, and convenience in drawing display is improved.
Step S303, determining the display proportion according to the drawing display instruction triggered by the user.
Step S304, obtaining a user identifier corresponding to the drawing display instruction.
Wherein the user identifications of different users are different, and the user identifications are unique identification codes of the users.
In one embodiment, the user identification may include a user number, e.g., 0145, user0147, where "user" is a preset character used to characterize the parameter as a user identification.
In one embodiment, the user identification of each user, such as zhangsan02, may be generated in the manner of name pinyin and numbering.
In one embodiment, the user identification may include the identity, job, or occupation of the user, such as Sale013 for sales personnel numbered 013.
In one embodiment, the drawing display instruction may include a user identifier, and the user identifier triggering the drawing display instruction may be obtained by analyzing the drawing display instruction.
In one embodiment, the user identification triggering the drawing display instruction user may be determined based on a manner of identifying the user image captured by the camera of the user device.
In one embodiment, when a user triggers a drawing display instruction of a building drawing through a finger touch instruction, a user identifier corresponding to the drawing display instruction can be determined by identifying a fingerprint of the user. And extracting fingerprint features in the drawing display instruction, and determining the user identification based on the fingerprint features.
Step S305, determining the target layer according to the user identifier and the display scale.
In one embodiment, a first correspondence corresponding to the user identifier may be determined based on the user identifier, and further, a target layer may be determined based on the first correspondence corresponding to the user identifier and the determined display scale.
In one embodiment, each layer that can be consulted by the user identification can be determined based on the user identification, and the target layer can be determined from each layer that can be consulted based on the determined display scale.
In one embodiment, based on the determined display scale, it may be determined that the scale range corresponding to the scale attribute in each layer that can be referred to includes each layer of the display scale, which is each target layer.
For example, taking a building drawing including 10 layers as an example, layers that can be referred to by the user identifier u0189 are layer 2 and layer 3, where the scale attribute of layer 2 is [1,1.5 ], the scale attribute of layer 3 is [1.5, 2), and the display scale determined based on the drawing scaling instruction is 1.8, then layer 3 can be determined to be the target layer.
Step S306, rendering and displaying the target layer.
Fig. 4A is a schematic diagram of interaction between a user device and a core device in the embodiment shown in fig. 3, fig. 4B is a schematic diagram of a display interface after the user device executes a drawing scaling instruction in the embodiment shown in fig. 4A, and as can be known from fig. 4A and fig. 4B, a currently logged-in user is U3147 (user identifier), a currently displayed interface of a display screen of the user device is a layer N1 (interesting layer of U3147) of a building drawing, in fig. 4A, by taking a touch screen of the user device triggered by a double click of the user U3147 by a finger as an example, based on the drawing scaling instruction, a display ratio is determined to be 1.5, a corresponding target layer is a layer N2, and then the user device requests data corresponding to the layer N2 to the core device and renders the layer N2, so that a display content of the display interface of the display screen is updated to be the layer N2, as shown in fig. 4B.
In one embodiment, due to the oversized construction drawing, the display range of the user device may be exceeded, that is, if the size of the construction drawing or the target layer is greater than a preset size, where the preset size may be the resolution of the user device or the size of the visible area of the current display interface, after determining the target layer, the target display data of the target layer may be determined based on the resolution of the user device or the size of the visible area, so as to render and display the target display data, where the size occupied by the target display data in the construction drawing is less than or equal to the preset size. After rendering and displaying the target display data, the rolling distance of the vertical rolling bar and the rolling distance of the horizontal rolling bar can be monitored, and based on the rolling distance of the vertical rolling bar and the rolling distance of the horizontal rolling bar, the display data of the corresponding area of the target layer is obtained, rendered and displayed so as to display the display data of each area of the target layer, and meanwhile, the data amount required to be processed by the user equipment when displaying the building drawing is further reduced, and the smoothness of drawing display is improved.
