Embodiment 1

[0039] Such as figure 1 As shown in Fig. 1, a method for generating the inspection path of leak detection vehicles in urban pipe network, the generation method of the inspection path is not only a planning method for the inspection path of leak detection vehicles, but also an optimization method for the inspection path of traditional leak detection vehicles ; The generating method specifically includes the following steps.

[0040] Step 1, obtain the gas pipeline network circuit diagram and road network circuit diagram in the area to be inspected. In this embodiment, the gas pipeline network circuit diagram is obtained by reading the gas pipeline network information database, and the gas pipeline network circuit diagram is obtained by reading the electronic map database. Way to get road network map. The "area to be inspected" should be understood as the designated area or target area to be inspected by the leak detection vehicle this time.

[0041] Step 2, select location po...

Embodiment 2

[0049] The technical solution of this embodiment is basically the same as that of Embodiment 1, and the difference is that this embodiment further improves the solution of how to effectively, quickly and reasonably determine the position point A and the position point B. On this basis, the How to calculate the length of the gas pipeline occupied by the grid covered by the shortest path and the total length of the gas pipeline network in the area to be inspected have been optimized. The specific improvement plan is as follows.

[0050] Such as figure 2 As shown, a method for generating an inspection path of an urban pipe network leak detection vehicle, the generation method includes the following steps:

[0051] Step 1. Obtain the gas pipeline network diagram and road network diagram in the area to be inspected.

[0052] In this embodiment, step 2 includes steps 2a, 2b and 2c, and position point A and position point B are selected in the following manner;

[0053] Step 2a, d...

Abstract

The invention discloses a generation method of an inspection route of a city pipe network leakage detection vehicle. The generation method comprises the following steps: obtaining a gas pipe network line map and a road network line map, selecting a position point A and a position point B with most dense pipe networks on the road network line map, obtaining the shortest route between the position point A and the position point B, and calculating a gas pipeline length covered by the shortest route and a current coverage rate; judging whether the current coverage rate is greater than or equal to the preset coverage rate; taking the shortest route corresponding to the current coverage rate which is greater than or equal to the preset coverage rate as the inspection route of the city pipe network leakage detection vehicle if the current coverage rate is greater than or equal to the preset coverage rate; and re-planning the shortest route until the condition of the preset coverage rate is met if the current coverage rate is not greater than or equal to the preset coverage rate. The generation method is capable of providing optimal inspection route for the city pipe network leakage detection vehicle, reducing or even avoiding inspection blind areas, meeting the requirements of the inspection coverage rate, improving the operating efficiency of inspection and providing the technical support for the integrity management of the city gas pipe network.

Description

technical field [0001] The invention relates to the technical field of urban gas pipeline network integrity management, and more specifically, the invention relates to a method for generating an inspection path of an urban pipeline network leak detection vehicle. Background technique [0002] Urban gas pipelines are buried underground, and a large number of urban gas pipelines form an urban gas pipeline network. Gas pipelines may leak after a long period of use. At present, the conventional pipeline network leak detection method is: use detection equipment to carry out leak detection along the pipeline, specifically, usually use a leak detection vehicle to carry out leak detection work, and the leak detection vehicle integrates the leak detection equipment into the car; although Compared with conventional trolley detection equipment, it has the advantages of fast driving speed, wide coverage and high detection efficiency. However, in the actual inspection work, due to the c...
