Generation method of inspection route of city pipe network leakage detection vehicle

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...

Problems solved by technology

[0004] In order to solve the problems of easy inspection blind spots and low inspection efficiency in the conventional inspection scheme, the present invention proposes a method for generating the inspection path of the urban pipe network leak detection vehicle, and innovatively optimizes the inspection path, thereby Guide the leak detection vehicle to travel along the generated inspection path and complete the inspection work. The inspection path generated by the present invention can cover most or even all pipelines in the area to be inspected to meet the inspection coverage requirements, thereby reducing or even The technical purpose of avoiding inspection blind spots; the leak detection vehicle travels along a reasonable, scientific and effective inspection path, thereby avoiding the problem of repeated detection of pipelines, thereby improving the inspection efficiency of the leak detection vehicle
