In the related art, the user can obtain the architectural drawings of the construction area through the terminal device to obtain the construction progress. At present, when the user operates the user drawings, the terminal device can load the corresponding architectural drawings locally. For example, when the user enlarges or reduces the architectural drawing displayed by the terminal device, the terminal device can locally load the enlarged or reduced architectural drawing. However, local loading of drawings by the terminal device will occupy a large amount of processing resources of the terminal device, causing the terminal device to freeze seriously, which in turn leads to low efficiency in displaying drawings by the terminal device.

A server acquires first layer information of a first drawing displayed by a terminal device, and receives an operation instruction sent by the terminal device, wherein the operation instruction is used to instruct a user to operate the first drawing. The operation instruction may be a user's zoom instruction for the first drawing, determine the first layer displayed on the first drawing and the first layer block displayed on the first layer according to the first layer information, and adjust the first drawing according to the zoom instruction.

Since the second drawing is a drawing obtained by the server locally rendering, the terminal device only needs to display the second drawing sent by the server. Drawings (eg, images) do not need to process the process of loading the second drawing locally on the terminal device, thereby improving the efficiency of displaying the second drawing on the terminal device.

Below, with reference to FIG. 1 , an application scenario of the present application will be introduced.

Wherein, the display screen of the terminal device displays the first drawing, and the server can obtain the first layer information of the first drawing currently displayed by the terminal device. When the server receives the operation instruction sent by the terminal device, the server can determine the second layer information according to the operation instruction and the first layer information, and render the second layer information to obtain the second drawing, and the server can send the information to the terminal device. Send the second drawing so that the terminal device displays the second drawing. In this way, since the second drawing is a drawing obtained by rendering locally by the server, the terminal device only needs to display the second drawing (eg, an image) sent by the server, and there is no need to process the process of loading the second drawing locally on the terminal device. The terminal device displays the efficiency of the second drawing.

The technical solutions of the present application and how the technical solutions of the present application solve the above-mentioned technical problems will be described in detail below with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

FIG. 2 is a schematic flowchart of a method for displaying drawings according to an embodiment of the present application. Referring to Figure 2, the method can include:

S201. Acquire first layer information of a first drawing displayed by a terminal device.

The execution subject of the embodiments of the present application may be a server, or may be a drawing display device provided in the server. Wherein, the drawing display device may be implemented by software, and the drawing display device may also be implemented by a combination of software and hardware.

Optionally, the first drawing may be a drawing currently displayed by the terminal device. For example, if the drawing currently displayed by the terminal device is a hydroelectric drawing, the server determines that the first drawing is a hydroelectric drawing, and if the drawing currently displayed by the terminal device is a piping drawing, the server determines that the first drawing is a piping drawing.

Optionally, the first layer information may be a layer corresponding to the first drawing and a layer block displayed by the layer. Optionally, the first drawing may include at least one layer. For example, an architectural drawing may include multiple layers. When a terminal device displays a hydropower drawing, the hydropower drawing includes multiple layers, and the contents of the hydropower drawing displayed on each layer are different. For example, layer A in the hydropower drawing is the waterway drawing of area A, layer B in the hydropower drawing is the waterway drawing of area B, and layer C in the hydropower drawing is the circuit drawing of area A and area B, through the waterway drawing Layer A, Layer B and Layer C in the area, you can get the waterway content and circuit content in area A and area B.

Optionally, a layer can include multiple layer blocks. For example, each layer in an architectural drawing can be evenly divided into multiple layer blocks (eg, each layer includes multiple grids of the same size), and each layer block includes parts of the layer content. For example, a water and electricity drawing includes layer A and layer B. Among them, layer A includes 100 layer blocks, and the content of layer A is displayed through 100 layer blocks, and layer B includes 1000 layer blocks. Displays the content of layer B through 1000 layer blocks.

Optionally, the server may determine the first layer information of the first drawing by using the drawing sent to the terminal device last time. For example, in the actual application process, the drawing displayed by the terminal device may be an image, the drawing to be displayed last sent by the server to the terminal device is the first drawing currently displayed by the terminal device, and the server may determine at least one layer corresponding to the drawing to be displayed , and the layer block included in each layer, and then the layer and the layer block are determined as the first layer information of the first drawing. For example, the last drawing sent by the server to the terminal device is a water and electricity drawing. The water and electricity drawing includes layer A and layer B. Layer A includes 10 layer blocks, and layer B includes 20 layer blocks. The server determines that the first layer information of the first drawing includes layer A, layer B and 30 layer blocks.

Optionally, if the terminal device displays the drawing for the first time, the server may obtain the drawing sent to the terminal device, and then obtain the first layer information. For example, if the terminal device requests to display the hydropower drawings, the server can send the hydropower drawings to the terminal device and obtain the layers and layer blocks corresponding to the hydropower drawings. When the user operates the hydropower drawings displayed by the terminal device, the server will display the hydropower drawings. The corresponding layer and layer block are determined as the first layer information.

Next, with reference to FIG. 3 , the process of acquiring the first drawing information of the first drawing by the server will be described.

FIG. 3 is a schematic diagram of a process for acquiring first layer information according to an embodiment of the present application. See Figure 3, including server and terminal equipment. Among them, the drawings sent by the server to the terminal equipment are water and electricity drawings. The water and electricity drawings include layer A and layer B, layer A includes layer block 1, layer block 2, layer block 3 and layer block 4, and layer B includes layer block 5 and layer block 6. The server determines that the drawing currently displayed by the terminal device is a hydroelectric drawing (which can be an image of a hydroelectric drawing), therefore, the server determines that the first layer information of the first drawing includes layer A, layer B, and layer blocks in layer A 1. Layer block 2, layer block 3 and layer block 4, and layer block 5 and layer block 6 in layer B.

S202. Receive an operation instruction sent by the terminal device.

Optionally, the operation instruction is used to instruct the user to operate the first drawing. For example, the server may determine the user's operation on the first drawing through the operation instruction. Optionally, the operation instruction may be a zoom instruction. Wherein, the zoom instruction may be a zoom-out command or a zoom-in command. For example, the reduction instruction is used to reduce the first drawing, and the enlargement instruction is used to enlarge the first drawing. For example, if the operation command sent by the terminal device to the server is a zoom-out command, the server determines, according to the zoom-out command, that the user performs a zoom-out operation on the first drawing. It is determined that the user performs an enlarging operation on the first drawing.

Optionally, the terminal device may determine the user's operation instruction on the first drawing in response to the user's operation. For example, when the user performs an opening and sliding operation on the display screen of the terminal device, the terminal device may determine that the operation command is a zoom-in command, and when the user performs a closing and sliding operation on the display screen of the terminal device, the terminal device may determine that the operation command is a zoom-out command . For example, when the terminal device receives an operation of sliding the mouse wheel upward, the terminal device may determine that the operation command is a zoom-in command, and when the terminal device receives an operation of sliding the mouse wheel downward, the terminal device may determine that the operation command is a zoom-out command.

Optionally, after determining the operation instruction, the terminal device may send the operation instruction to the server. For example, when the user opens and slides the display screen of the terminal device, the terminal device generates an enlargement instruction and sends the enlargement instruction to the server, and the server determines, according to the enlargement instruction, that the user performs an enlargement operation on the first drawing displayed by the terminal device .

Next, with reference to FIG. 4 , the process of the server receiving the operation instruction sent by the terminal device will be described.

FIG. 4 is a schematic diagram of a process of receiving an operation instruction according to an embodiment of the present application. See Figure 4, including server and terminal equipment. The first drawing is displayed on the display screen of the terminal device. When the user performs an opening and sliding operation on the display screen of the terminal device, the terminal device generates an enlargement instruction according to the opening and sliding operation, and sends the enlargement instruction to the server.

S203. Process the first layer information according to the operation instruction to obtain the second layer information.

Optionally, the operation instruction is a zoom instruction, and the second layer information is layer information obtained after zooming the first drawing. Optionally, the second layer information may be obtained according to the following feasible implementation method: according to the first layer information, the first layer displayed on the first drawing and the first layer block displayed on the first layer are determined. For example, if the first layer information is layer A, layer B, 10 layer blocks in layer A, and 5 layer blocks in layer B, the server determines the first layer according to the first layer information. One layer is layer A and layer B, and the first layer block includes 10 layer blocks in layer A and 5 layer blocks in layer B.

The first layer and the first layer block are zoomed according to the zoom instruction to obtain the second layer information. For example, when the operation command is a zoom-in command, the zoom-in command is used to determine the layer after the first layer is zoomed in, and the layer is determined as the second layer, and the zoom-in command is used to determine the second layer displayed after the first layer is zoomed in. The layer block included in the layer is determined as the second layer block, and the second layer information is obtained through the second layer and the second layer block.

S204. Render the second layer information to obtain a second drawing.

Optionally, the server may acquire the second drawing corresponding to the second layer information according to the second layer information, and obtain the second drawing by rendering. For example, if the second layer information includes layer A, layer B, 10 layer blocks in layer A, and 20 layer blocks in layer B, the server renders the second layer information to obtain a second drawing, wherein the second drawing includes layer A, layer B, 10 layer blocks in layer A, and 20 layer blocks in layer B. In this way, the server can accurately obtain the second layer information after the user operates the first drawing through the operation instruction, and render the second drawing locally according to the second layer information, so as to avoid the freeze caused by the terminal device loading the drawing, and further Improve the efficiency of terminal equipment displaying drawings.

S205. Send the second drawing to the terminal device.

Optionally, after obtaining the second drawing, the server may send the second drawing to the terminal device, so that the terminal device displays the second drawing. For example, after the server renders the second drawing locally through the second layer information, it can send the image corresponding to the second drawing to the terminal device, and the terminal device can display the image when receiving the image. In this way, the server loads the drawing locally, and the terminal The equipment does not need to deal with the process of loading drawings, thereby improving the efficiency of terminal equipment drawing display.

An embodiment of the present application provides a method for displaying a drawing. A server acquires first layer information of a first drawing displayed by a terminal device, and receives an operation instruction sent by the terminal device, wherein the operation instruction is used to instruct a user to operate the first drawing. The operation instruction may be a user's zoom instruction for the first drawing, determine the first layer displayed on the first drawing and the first layer block displayed on the first layer according to the first layer information, and adjust the first drawing according to the zoom instruction. The layer and the first layer block are zoomed to obtain the second layer information, the second layer information is rendered, the second drawing is obtained, and the second drawing is sent to the terminal device. In the above method, since the second drawing is a drawing obtained by rendering locally by the server, the terminal device only needs to display the second drawing (eg, an image) sent by the server, and there is no need to process the process of loading the second drawing locally on the terminal device , thereby improving the efficiency of displaying the second drawing by the terminal device.

On the basis of the embodiment shown in FIG. 2 , the process of the above drawing display method will be further described below with reference to FIG. 5 .

FIG. 5 is a schematic flowchart of another method for displaying drawings according to an embodiment of the present application. Referring to Figure 5, the method flow includes:

S501. Acquire first layer information of a first drawing displayed by a terminal device.

It should be noted that, for the execution process of step S501, reference may be made to step S201, which is not repeated in this embodiment of the present application.

S502. Receive a scaling instruction sent by the terminal device.

Optionally, the zoom instruction is used to instruct the user to perform a zoom operation on the first drawing. For example, when the user performs a zoom operation on the display screen of the terminal device, the terminal device may generate a zoom instruction, and send the zoom instruction to the server.

S503. Determine the first layer displayed on the first drawing and the first layer block displayed on the first layer according to the first layer information.

It should be noted that, for the execution process of step S503, reference may be made to the relationship between drawings, layers, and layer blocks shown in FIG. 3 in step S201, which is not repeated in this embodiment of the present application.

S504. Perform zoom processing on the first layer and the first layer block according to the zoom instruction to obtain second layer information.

Optionally, the second layer information may be obtained according to the following feasible implementation manner: determining the zoom ratio and zoom position corresponding to the zoom command. The scaling ratio is the scaling size of the first drawing. For example, the enlargement ratio may be 2 times, 5 times, or 10 times for the first drawing, or the reduction ratio may be 2 times, 5 times, 10 times, etc. for the first drawing. Optionally, the zoom action of the user on the terminal device may be acquired, and then the zoom ratio is determined through the zoom action. For example, through the user's zooming action on the terminal device, the moving distance corresponding to the zooming action is determined, and then the zooming ratio is obtained according to the moving distance and a first preset relationship, wherein the first preset relationship includes at least one moving distance and each moving distance. The scaling ratio corresponding to the distance. For example, the first preset relationship may be as shown in Table 1:

Table 1

Moving distance scaling ratio distance 1 Scaling 1 distance 2 Scaling 2 distance 3 Scaling 3 ... ...

It should be noted that, Table 1 only illustrates the first preset relationship in the form of an example, and is not a limitation on the first preset relationship.

For example, if the moving distance corresponding to the user's zoom action on the terminal device is distance 1, the terminal device determines that the zoom ratio is zoom ratio 1; if the moving distance corresponding to the user's zoom action on the terminal device is distance 2, the terminal device determines the zoom ratio The ratio is zoom ratio 2; if the moving distance corresponding to the zoom action of the user on the terminal device is distance 3, the terminal device determines the zoom ratio as zoom ratio 3. In this way, the server can accurately determine the user's operation on the first drawing according to the zooming action of the user, thereby realizing the effect of loading the drawing in the server, and improving the drawing display efficiency.

Optionally, the zoom position is the zoom center corresponding to the zoom command. For example, if the user performs a zoom operation on the center of the first drawing, the zoom position is the center of the first drawing; if the user performs a zoom operation on the upper left corner of the first drawing, the zoom position is the upper left corner of the first drawing. For example, the zoom position can be the position of the mouse when the user performs a zoom operation.

According to the zoom ratio, determine the second layer after the first layer is zoomed. For example, if the first layer is layer A in the drawing, and after processing the first drawing through scaling, the layer of the second drawing displayed by the terminal device is layer B, and the server determines layer B as the first drawing. Second layer.

Determine the second layer block after the first layer block is scaled according to the zoom ratio and the zoom position. Optionally, the second layer block may be determined according to the following feasible implementation methods: taking the zoom position as the zoom center, and according to the zoom ratio, the first layer block is zoomed, and after the first layer block is zoomed, The layer block to be displayed in the second layer is determined as the second layer block. For example, if the first layer includes 30 first layer blocks, after the first layer is scaled by the zoom ratio, the second layer is obtained, and the 30 first layer blocks will also be scaled with The processing is scaled, resulting in a second layer block. For example, the display area of the terminal device includes 30 layer blocks of the first layer. After the first layer is zoomed, the display area of the terminal device displays 10 layer blocks of the second layer. Then, these 10 layer blocks are determined as the second layer block. Since the zoom position can be the drawing area that the user is mainly concerned about, the server can flexibly and accurately send the drawing content of the user's attention to the terminal device, thereby improving the display effect of the drawing.

Next, with reference to FIG. 6 , the process of determining the second layer block by the server will be described.

FIG. 6 is a schematic diagram of a process for determining a second layer block according to an embodiment of the present application. Please refer to Figure 6, including the first layer and the second layer. The first layer includes layer block 1 , layer block 2 , layer block 3 and layer block 4 . The zoom position is the center of layer block 2, and the zoom ratio is 2 times larger. After the first layer is enlarged by 2 times, the second layer is obtained. After zooming the layer blocks in the first layer with the zoom position as the zoom center, 16 layer blocks are displayed in the second layer. The second layer and the 16 layer blocks in the second layer are determined as the second layer information.

S505. Render the second layer information to obtain a second drawing, and send the second drawing to the terminal device.

Optionally, the second drawing may be sent to the terminal device according to the following feasible implementation manner: acquiring network parameters of the terminal device, and sending the second drawing to the terminal device according to the network parameters. The network parameter is used to indicate the network signal strength of the terminal device. For example, the server can obtain the current network speed of the terminal device through network parameters.

Optionally, sending the second drawing to the terminal device according to the network parameter, specifically: determining the network duration for sending the second drawing to the terminal device according to the network parameter. For example, after the server renders and obtains the second drawing, it can send the image of the second drawing to the terminal device, and the server can determine the duration for the terminal device to receive the image of the second drawing through the network parameters of the terminal device.

When the network duration is less than or equal to the first threshold, the second drawing is sent to the terminal device. For example, if the network duration is less than or equal to the first threshold, it means that the current network status of the terminal device is good. Therefore, the server can quickly send the second drawing to the terminal device to improve the efficiency of displaying the second drawing on the terminal device. Optionally, when the network duration is greater than the first threshold, the second drawing may be sent to the terminal device by means of multi-layer loading. In this way, the server can send the second drawing to the terminal device when the network state is good, thereby improving the reliability of sending the drawing by the server.

S506. Receive the editing operation sent by the terminal device.

Optionally, the editing operation is an operation performed by the user on the second drawing. For example, when the terminal device receives the second drawing, the user can edit the second drawing in the terminal device (eg, modify parameters, zoom operations, etc.), and the terminal device can generate an edit according to the user's editing process of the second drawing operation and send the edit operation to the server. For example, when the terminal device displays the second drawing, if the user deletes a line content in the second drawing, the terminal device generates an editing operation for deleting the line content, and sends the editing operation to the server.

S507, according to the editing operation, update the data of the second drawing.

Optionally, when the server receives the editing operation, it may determine the user's operation on the second drawing according to the editing operation, and update the data of the second drawing in the server. For example, in the actual application process, the layer data of all drawings can be stored in the database of the server. When the user modifies the data of the second drawing on the terminal device, the server can timely update the second drawing in the database according to the editing operation. The data is updated synchronously, so that accurate data can be obtained when the drawing is loaded next time, and the accuracy and efficiency of drawing display can be improved.

An embodiment of the present application provides a drawing display method, which acquires first layer information of a first drawing displayed by a terminal device, receives a zoom instruction sent by the terminal device, and determines a first drawing displayed by the first drawing according to the first layer information layer and the first layer block displayed by the first layer, perform zoom processing on the first layer and the first layer block according to the zoom instruction to obtain the second layer information, and render the second layer information to obtain the first layer information. Second drawing, send the second drawing to the terminal device, receive the editing operation sent by the terminal device, and update the data of the second drawing according to the editing operation.
