The following describes the technical solution of the present application and how to solve the above technical problems in detail by specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated 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 construction 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 display method of the construction drawing includes:
step S201, determining a display scale according to a drawing display instruction triggered by a user.
The drawing display instruction can be an instruction for opening the building drawing or a zooming instruction for the currently displayed building drawing. The user can trigger the drawing display instruction in a mode of inputting the instruction in user equipment, such as a mobile terminal. Such as inputting gesture commands through a touch screen, inputting commands through input devices such as a mouse and a keyboard, and the like. The display scale can be expressed in the form of percentage, decimal, 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 an embodiment, the drawing display instruction may be a drawing scaling instruction, such as a drawing enlarging instruction and a drawing reducing 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 zooming operation can be a double-click operation, a double-finger operation, a mouse sliding operation, a long-press operation, an input operation and the like.
When a zoom ratio is included in the zoom operation, the display ratio is determined based on the zoom ratio. When the zoom operation does not include the zoom scale, the display scale may be determined based on parameters such as the number of times of the zoom operation, the operation time, the gesture trajectory, and the like.
For example, in the case of the two-finger operation, the display scale may be determined by the distance between the two fingers, and the larger the distance is, the larger the display scale is. Taking the double-click operation as an example, each time the number of times of the double-click operation is increased, the display ratio is increased by a set step length, such as 0.1, 0.2 and the like, on the basis of the original ratio.
In one embodiment, the user may trigger the drawing display instruction by opening a drawing to display a corresponding program or by clicking a preset link.
Specifically, when a user triggers a drawing display instruction or receives the drawing display instruction, the display scale of the current display interface of the user equipment is determined, where the display scale may be a default scale or a common scale corresponding to the user.
In one embodiment, the display scale may be determined according to a drawing display instruction triggered by a user and a user identifier corresponding to the drawing display instruction. If the current display scale can be determined based on the corresponding relationship among the user identifier, the drawing display instruction and the display scale, and the currently triggered drawing display instruction and the user identifier triggering the drawing display instruction, the determined display scales may be different when different users trigger the same drawing display instruction.
In one embodiment, the corresponding relation between the user identification, the drawing display instruction and the display scale of the user can be established according to the historical operation record of the user.
For example, when the user u1 and the user u2 use the same gesture instruction (e.g., a two-finger zoom instruction) to perform zoom control on the building drawing, the display scale corresponding to the user u1 may be 1.5, and the display scale corresponding to the user u2 may be 1.6.
And 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 under a corresponding display scale.
In one embodiment, the layer may include display data for one or more areas of the construction drawing.

For example, the layers of the building drawing can include a component layer, a label layer, a power layer, a fire protection layer, a heating and ventilation layer, a water supply and drainage layer and the like.
In one embodiment, a display scale may correspond to one or more layers.
In one embodiment, the target layer of the construction drawing can be determined according to the first corresponding relation established in advance and the determined display scale. The first corresponding relation is used for describing the corresponding relation between each display scale and the layer of the building drawing.
In an 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 currently logged-in user or a user identifier corresponding to the drawing display instruction, so as to determine the target drawing layer of the building drawing based on the first relationship corresponding to the user and the determined display scale.
In one embodiment, when designing a building drawing, a plurality of layers may be set for the building drawing according to requirements, and a scale attribute is added to each layer, and if a visible scale range is found, the layers of the building drawing may be screened based on the determined display scale and the scale attribute, so as to determine one or more target layers corresponding to the display scale.
For example, the layers 1-10 may be set to correspond to a display scale of 100% and the layers 11-20 may be set to correspond to a display scale of 120% by the scale attribute. The proportion attribute can also be used for setting the layer 1 to correspond to the display proportion of 100%, and the layer 2 to correspond to the display proportion of 110%.
In one embodiment, a drawing display instruction triggered by a user is taken as a drawing scaling instruction as an example, the drawing scaling instruction is triggered by the user through a manner of inputting a scaling operation, during the period that the user inputs the scaling instruction, a dynamic display layer of the building drawing can be determined based on display proportions corresponding to various time nodes, and the dynamic display layer is rendered and displayed by corresponding time nodes, so that the control response speed of the building drawing is increased, and the dynamic effect of the drawing scaling display is improved.
The interval between adjacent time nodes may be 0.1s, 0.2s, or other time intervals.
In an embodiment, for each time node, a dynamic display layer corresponding to the time node may be determined according to the display scale of the time node, a specific manner is similar to that in step S202, and only the target layer is replaced with the dynamic display layer, which is not described herein again.
And step S203, rendering and displaying the target layer.
Specifically, after the target layer is determined, 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 an embodiment, after the target layer is determined, an associated layer of the target layer may also be determined based on the layer association relationship of the building drawing, and the target layer and the associated layer thereof are rendered and displayed. The association relationship may be determined based on the association attribute of the layer.
In one embodiment, the association attribute may be added to each layer when the layer of the building drawing is set.

In an embodiment, when determining the target layer, a user identifier may also be considered, that is, the target layer is determined based on the user identifier and a drawing display instruction triggered by a user. The user identification is the user identification corresponding to the drawing display instruction, or the user identification of the user triggering the drawing display instruction.

The user equipment is a device used for displaying the construction drawing at a local side or a user side, and a user can trigger the drawing display instruction through the user equipment, for example, a zoom instruction is input on the user equipment. The performance parameters of the user device may include parameters of a Central Processing Unit (CPU) and an image processor (GPU) of the user device.
Specifically, the layers of the building drawing may be screened based on the display scale to obtain a plurality of layers corresponding to the display scale, and then a target layer to be finally rendered and displayed is determined from the plurality of layers corresponding to the display scale based on the performance parameter of the user equipment.
In an embodiment, an upper limit number of layers that can be rendered at one time may be determined based on a performance parameter of the user equipment, and based on the upper limit number, when the number of the plurality of layers corresponding to the display ratio is greater than the upper limit number, the upper limit number of layers may be determined to be each target layer from the plurality of layers corresponding to the display ratio.
By combining the performance parameters of the user equipment, the target layers are determined, 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 drawing rendering fluency is further improved.

After the authentication is passed, based on the account, or based on the account number and the password, a user identifier, such as a user identifier, is determined as the account number input by the user, such as U0213 in fig. 5. The display device determines an interest layer of the building drawing corresponding to the user based on the user identifier, and updates a display interface of the local device based on the interest layer, where fig. 5 takes the interest layer as an example of an overall plan view of a certain residential building. If the interest is not the layer desired by the user, the user inputs a zoom instruction (one of drawing display instructions), such as a double-click instruction, in the area of the display interface of the local device where the interest layer is displayed. The display device receives the scaling instruction, determines a target layer of the building drawing (taking the layer where the plan view with the target layer being 201 chambers is located in fig. 5 as an example) based on the display scale corresponding to the scaling instruction and the area of the display interface corresponding to the scaling instruction (the area corresponding to 201 chambers is shown in fig. 5), and sends the target layer to the local device, so that the display interface of the local device is updated based on the target layer, and the target layer is rendered at the local device, so that only data of the target layer need to be rendered, and the amount of rendered data is greatly reduced.
