Embodiment Construction

[0031] Such as Figure 1 to Figure 6 Among them, a drainage pipe network monitoring and distribution method suitable for defect pipeline investigation, it includes the following steps:

[0032] Step 1, topology, analyze the topology structure of the pipe network in the target area, and divide the pipe level, pipe section and pipe joint of the pipe network;

[0033] Step 2, analyze, compare and analyze the detection data of the flow sensor, and obtain the mapping relationship between the flow sensor and the pipeline defect situation;

[0034] Step 3, setting, setting the applicability of the arrangement of "straight line" and "hook" sensor groups;

[0035] Step 4, laying out, first laying out the "hook" sensor group in the unit of pipe section, and then laying out the "linear" sensor group for the pipe joints in the pipe section. In this step, according to the principle of "the length of the pipeline that enables the sensor group to achieve accurate judgment is the largest, a...

Abstract

The invention discloses a drainage pipe network monitoring point distribution method suitable for defective pipeline troubleshooting. The drainage pipe network monitoring point distribution method suitable for defective pipeline troubleshooting comprises the steps that topological structure analysis is conducted on a pipe network of a target area, and the pipe levels, pipe sections and pipe joints of the pipe network are divided; detection data of a flow sensor are compared and analyzed to obtain a mapping relation between the flow sensor and pipeline defect conditions; the application condition of a linear type and hook type sensor group arrangement mode is set; a hook type sensor group is arranged by taking a pipe section as a unit, and then a linear type sensor group is arranged on the pipe joints in the pipe sections. Therefore, the defective pipeline troubleshooting range is narrowed to the maximum extent through a limited number of monitoring equipment, the blindness of monitoring point distribution is avoided, and the utility value of the monitoring equipment is improved.

Description

technical field [0001] The patent of the invention belongs to the technical field of pipe network monitoring, and relates to a drainage pipe network monitoring and layout method suitable for faulty pipe inspection. Background technique [0002] As an important part of urban infrastructure, drainage pipes are an important support to ensure the safety of urban drainage. During the operation of the pipeline network, due to factors such as irregular construction during the construction period, unscientific selection of pipe materials, natural aging and damage, etc., the situation of "sick operation" of the pipeline network is common, and the inspection of defective pipe sections has become a daily task of the pipeline network. Important content of operation and maintenance. [0003] At present, when inspecting defective pipelines, the pipeline inspection is mainly carried out through manual experience and supplemented by CCTV inspection robots to detect whether there are defect...
