Description

[0002] TGNET is widely used at home and abroad to simulate the flow direction and flow distribution of pipelines in complex pipeline networks. After the simulation is completed, data is usually manually extracted from node stations one by one and then filled into the specified location. However, for "spider-web" and "multi-branch" long-distance pipeline networks, there are many node stations and complex flow directions. When using manual input and output, errors and errors are prone to occur, and the workload is heavy and repetitive. Generally, for a pipeline network with 100 node stations and more than 1,000 km of pipelines, it often takes 1 to 2 days to obtain a working condition simulation diagram of the entire pipeline network using a point-to-point method, which is inefficient. Summary of the invention

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The following operations are all implemented based on Python's GUI automation control program, which mainly uses the Pyautogui library. Pyautogui can simulate mouse and keyboard input by writing scripts, thereby realizing automated control of graphical interface (GUI) software.

[0033] Figure 1 A schematic diagram of a flow chart of a method for generating a pipe network flow direction display diagram provided by an embodiment of the present invention. Figure 1 As shown, the method for generating a pipe network flow direction display diagram according to an embodiment of the present invention specifically includes the following steps:

[0034] S101: Obtain station information in the pipeline network, where the station information includes: station name, station pressure, and connecting pipelines between stations.

[0035] The specific acquisition method is: batch export the pipe network data in TGNET in the data result column of TGNET software.

[0036] There are many station names obtained, each name represents a station, and each station name has a corresponding station pressure.

[0037] When the station name appears repeatedly, the station name is only displayed once. Specifically, in the acquired station information, when the same station name appears repeatedly, the station name that appears multiple times is deduplicated, and the same station name is only displayed once in the end, and other repeated station names are deleted.

[0038] The acquired station information may also include station output flow and station input flow; therefore, the method further includes: judging whether the flow is balanced based on the station output flow and the station input flow.

[0039] Specifically, the station output flow is subtracted from the station input flow. When the result is 0, it means the flow is balanced. If the result is not 0, it means the flow is unbalanced, which means that the TGNET software simulation data is abnormal.

[0040] At this time, since each repeated station name corresponds to a station output flow, the multiple station output flows corresponding to the repeated station names are added together to obtain the total output flow of the station. When the same station name appears repeatedly, the station input flow corresponding to each station name is the same, so you only need to take any station input flow to display.

[0041] S102: Determine the station location based on the station name.

[0042] Since the names of the stations are all named after place names, the coordinate information of the place names can be obtained from Baidu Maps to determine the specific location of the station.

[0043] S103: Based on the station location, the station name and station pressure are displayed in a chart.

[0044] In the chart, the stations are displayed according to their specific locations and directions. The display method is based on the principle of south at the top, north at the bottom, west on the left, and east on the right. For example, station A is located to the east of station B, and station A is displayed to the right of station B in the chart; for another example, station C is located to the northwest of station D, and station C is displayed to the upper left of station D in the chart.

[0045] S104: Based on the connecting pipelines and station pressures between stations, arrows are used to mark the names of the connected stations in the diagram to form a flow direction display diagram.

[0046] If there is a connecting pipeline between the two stations, it is marked by a single arrow along the direction of fluid flow in the pipeline.

[0047] Since each station name corresponds to the station pressure of the station, the flow direction of the fluid in the pipeline is from the side with higher station pressure to the side with lower station pressure, so the single-direction arrow points from the side with higher pressure to the side with lower pressure.

[0048] The station names pointed to by at least three arrows are marked as hub stations. Multiple station names are displayed in the entire display diagram. When a station name has at least three single arrows pointing to it, the station name pointed to by the single arrow is determined to be a hub station, and the hub station is marked with a color to remind it prominently.

[0054] It should be noted here that the above-mentioned acquisition module 201, determination module 202, display module 203 and marking module 204 correspond to steps S101 to S104 in the embodiment of the method for generating a pipe network flow direction display diagram, and the examples and application scenarios implemented by the above-mentioned modules and corresponding steps are the same, but are not limited to the contents disclosed in the above-mentioned embodiments.
