The embodiment of the invention provides a pipeline digital map display method, and referring to fig. 2A, the method comprises the following steps:
step 201: the terminal acquires the pipeline position information and the pipeline attribute information of a plurality of pipelines.
It should be noted that the pipe position information may include a pipe direction, a pipe two-dimensional coordinate, and a position relationship between the pipe and the surrounding environment, and of course, the pipe position information may also include other information. The pipeline attribute information may include a pipeline elevation and a pipeline burial depth, and certainly, the pipeline attribute information may also include other information such as a crossing manner, a distribution condition of accessory equipment of the pipeline, and the embodiment of the present invention is not particularly limited to this.
In addition, the terminal can acquire not only the pipeline position information and the pipeline attribute information of a plurality of pipelines, but also a plurality of thematic information and a plurality of display position information, wherein the plurality of display position information are position information for displaying the plurality of thematic information. In addition, the topic information may include a risk topic, a pipeline centerline topic, and the like, and correspondingly, the display position information may include position information of the risk topic, position information of the pipeline centerline topic, and the like, which is not specifically limited in the embodiment of the present invention.
Step 202: the terminal converts the acquired pipeline position information of the plurality of pipelines into pipeline position vector information and sends a mapping request to the server.
It should be noted that, after the terminal acquires the pipeline position information and the pipeline attribute information of the multiple pipelines, the acquired pipeline position information of the multiple pipelines may be converted into the pipeline position vector information, the conversion may be performed in a manner that the pipeline position information of the multiple pipelines is imported into a vectorization application or a plug-in, and the pipeline position information of the multiple pipelines is converted into the pipeline position vector information by the vectorization application or the plug-in, or may be converted by other manners, which is not specifically limited in this embodiment of the present invention.
In addition, after the terminal acquires the multiple pieces of topic information and the multiple pieces of display position information, the acquired multiple pieces of display position information may also be converted into topic position vector information, where the conversion may be performed in a manner that the multiple pieces of display position information are imported into a vectorization application or a plug-in, and the multiple pieces of display position information are converted into topic position vector information through the vectorization application or the plug-in, or may be converted through another manner, which is not specifically limited in this embodiment of the present invention.
It should be noted that the map drawing request may carry the pipeline position vector information and the pipeline attribute information of the plurality of pipelines, so that the server may draw the pipeline digital map based on the pipeline position vector information and the pipeline attribute information of the plurality of pipelines.
Therefore, after the terminal converts the pipeline position information of the plurality of pipelines into the pipeline position vector information, a mapping request carrying the pipeline position vector information and the pipeline attribute information of the plurality of pipelines can be sent to the server, and then after the server receives the mapping request, the server can map a pipeline digital map which needs to be displayed at the terminal.
In addition, the map drawing request may also carry a plurality of thematic information and thematic position vector information, and further, when the server draws the pipeline digital map, the plurality of thematic information may be displayed in the pipeline digital map based on the thematic position vector information, which is not specifically limited in the embodiment of the present invention.
Step 203: when the server receives the map drawing request, the pipeline digital map is drawn based on the pipeline position vector information and the pipeline attribute information.
When the server receives a map drawing request sent by the terminal, the server can draw a pipeline digital map based on the pipeline position vector information and the pipeline attribute information carried in the map drawing request. Specifically, the server may import the pipeline position vector information and the pipeline attribute information into a digital mapping application or a plugin, and draw a pipeline digital map through the digital mapping application or the plugin based on the imported pipeline position vector information and the pipeline attribute information, or draw the pipeline digital map in other manners, which is not specifically limited in this embodiment of the present invention.
In addition, because the map drawing request can also comprise a plurality of thematic information and thematic position vector information, the server can draw the pipeline digital map based on the pipeline position vector information, the pipeline attribute information, the plurality of thematic information and the thematic position vector information carried in the map drawing request. Specifically, the server may import the pipeline position vector information, the pipeline attribute information, the multiple topic information, and the topic position vector information into a digital map making application or a plug-in, and draw a pipeline digital map through the digital map making application or the plug-in based on the imported pipeline position vector information, the pipeline attribute information, the multiple topic information, and the topic position vector information, or draw the pipeline digital map through other manners, which is not specifically limited in the embodiment of the present invention.
After the server finishes drawing the pipeline digital map, when the server receives a map display request sent by the terminal, the drawn pipeline digital map can be sent to the terminal, and then the terminal can display the pipeline digital map. The method comprises the following steps.
Step 204: the terminal sends a map display request to the server.
Step 205: when the server receives the map display request, the stored pipeline digital map is transmitted to the terminal.
After the server receives the map display request, the server may transmit the stored pipeline digital map to the terminal.
Step 206: and when the terminal receives the pipeline digital map sent by the server, displaying the pipeline digital map.
In a possible implementation manner, when the terminal receives the pipeline digital map sent by the server, the terminal may further obtain the geographical location information of the current location of the terminal, and further, when the pipeline digital map is displayed, the current location of the terminal may be marked in the pipeline digital map based on the geographical location information of the current location of the terminal.
It should be noted that, referring to fig. 2B, the digital pipeline map displayed by the terminal may display not only the pipeline position information of the multiple pipelines, but also multiple special options, and when the terminal detects a trigger operation of any special option in the multiple special options, the terminal may display special information corresponding to the special option, which is not specifically limited in the embodiment of the present invention.
The triggering operation may be triggered by a user, and the user may trigger through a preset operation, for example, a click operation, a double click operation, a sliding operation, and the like, which is not specifically limited in this embodiment of the present invention.
In addition, when the terminal receives the pipeline digital map sent by the server, the terminal may display the pipeline digital map through a pop-up window, or may display the pipeline digital map through other manners, which is not specifically limited in this embodiment of the present invention.
Step 207: when the terminal detects the triggering operation of a first target position on a target pipeline in a pipeline digital map, pipeline attribute information of a plurality of positions in a preset range on the target pipeline is obtained based on the first target position, the target pipeline is any one of the plurality of pipelines, and the first target position is any one position on the target pipeline.
The implementation process of the terminal for acquiring the pipeline attribute information of a plurality of positions in the preset range on the target pipeline based on the first target position can be as follows: determining two-dimensional coordinates of a plurality of positions within a preset range on a target pipeline in a pipeline digital map based on the first target position; determining one-dimensional mileage of the plurality of positions on the target pipeline based on the two-dimensional coordinates of the plurality of positions in the pipeline digital map; and acquiring the pipeline elevations and the pipeline burial depths at the positions from the stored corresponding relation among the pipeline mileage, the pipeline elevation and the pipeline burial depth based on the one-dimensional mileage of the positions on the target pipeline.
Specifically, the terminal may determine a plurality of positions within a preset range from a target pipeline, where a central point of the preset range is a first target position, obtain two-dimensional coordinates of the plurality of positions from the pipeline digital map, convert the two-dimensional coordinates of the plurality of positions in the pipeline digital map into one-dimensional mileage, obtain, for each of the plurality of positions, a corresponding pipeline elevation and a corresponding pipeline burial depth from a stored corresponding relationship among the pipeline mileage, the pipeline elevation and the pipeline burial depth based on the one-dimensional mileage of the position on the target pipeline, determine the pipeline elevation at the position from the obtained pipeline elevation, and determine the pipeline burial depth at the position from the obtained pipeline burial depth.
It should be noted that the preset range may be set by the terminal in advance, for example, the preset range is a pipe section of a target pipeline in a range of 5 kilometers, and a central point of the pipe section in the range of 5 kilometers is the first target position.
For example, the terminal may determine five positions 1-5 within a range of 5 kilometers from a target pipeline, and a center point of a pipe section within the range of 5 kilometers is a position 3, obtain the two-dimensional coordinates of the position 1, which are 37 degrees north latitude and 19 degrees east longitude and 13 degrees east longitude, from the pipeline digital map, convert the position 1 into the two-dimensional coordinates of the position 1, which are 37 degrees north latitude and 19 degrees east longitude and 116 degrees 13 degrees east longitude, and convert the two-dimensional coordinates of the position 1 into the one-dimensional mileage of the position 1, which is 131 kilometers, and obtain, based on the one-dimensional mileage of the position 1, a pipeline height corresponding to the position 1, which is 9 meters and a pipeline buried depth, which are 1.5 meters from the corresponding relationship among the pipeline mileage, the pipeline height and the pipeline buried depth shown in table 1 below. Similarly, the two-dimensional coordinates of the position 2, namely the north latitude 37 degrees 21 minutes and the east longitude 116 degrees 17 minutes, are obtained from the pipeline digital map, the two-dimensional coordinates of the position 2, namely the north latitude 37 degrees 21 minutes and the east longitude 116 degrees 17 minutes, are converted into the one-dimensional mileage of the position 2, namely 131.4 kilometers, and based on the one-dimensional mileage of the position 2, namely 131.4 kilometers, the height of the pipeline corresponding to the position 2 and the buried depth of the pipeline are obtained from the corresponding relationship among the mileage, the height of the pipeline and the buried depth of the pipeline, which are stored in the following table 1, wherein the corresponding relationship among the altitude of the pipeline, the height of the pipeline and the buried depth of the pipeline is 10 meters. Of course, in the same way, the height of the pipeline corresponding to the position No. 3 can be obtained to be 9.6 meters and the buried depth of the pipeline can be obtained to be 1.7 meters; the height of the pipeline corresponding to the position No. 4 is 8.8 meters and the buried depth of the pipeline is 0.9 meter; the height of the pipeline corresponding to the position No. 5 is 9.1 meters and the buried depth of the pipeline is 1.2 meters.

| Position No. 3 | 132.5 km | 9.6 m | 1.7 m |
| Position No. 4 | 133.8 km | 8.8 m | 0.9 m |
| Position No. 5 | 134.1 km | 9.1 m | 1.2 m |
