Problems solved by technology

In the process of use, the water supply pipe network often leaks due to some man-made or non-man-made factors, and many of the leaks are relatively hidden and difficult to be discovered by people. Water is safe, and in the long run it will cause a great waste of water resources
[0003] However, in the face of the increasingly complex water supply network system in today's society, the existing methods for monitoring leakage, especially in the case where there are multiple water supply plants connected to the water supply network system in the same area, the water supply network in the area There will be multiple water inlets in the system. At this time, due to the different water pressures of each water supply plant, the water flow direction may be uncertain in the water pipe section in such an area, which will further increase the impact on the leakage area. It is difficult to monitor and the monitoring efficiency is low

Embodiment 1

[0042] This embodiment is a method for establishing a multi-channel water supply structure leakage monitoring pipeline network, which is characterized in that it includes the following steps:

[0043] Step 1: Delineate a number of different monitoring areas according to the direction of the existing urban water supply network;

[0044] In each monitoring area, multiple water supply pipes are directly or indirectly connected to form a water supply network unit. The water supply network unit in each monitoring area has multiple water inlets and outlets; the water supply network units in each monitoring area are connected to each other through corresponding water inlets and outlets to form a network Describe the urban water supply network,

[0045] Among the water supply pipes in each water supply network unit, the pipe whose two ends are directly connected with the two water inlets and outlets is the main pipe A1, and each main pipe A1 is directly branched out and has one end di...

example 1

[0070] Through system data monitoring, it is found that the net inflow of water in the monitoring area is 75 cubic meters per hour, while the sum of the unit water volume data collected from the intelligent remote water meter B2 of each branch is 70 cubic meters per hour, and the water volume is unbalanced , the calculation shows that the leakage rate of the main pipeline A1 is 6.6%, which exceeds the set warning leakage rate, so the leakage of the main pipeline A1 is suspected and further analysis of the leakage is carried out; Use the pressure change value and time difference to locate the leakage site of the main pipeline A1 where the leakage occurs, and finally assign corresponding personnel to find the specific leakage point and take corresponding measures in time.

[0071] Example 2:

[0072] Through system data monitoring, it is found that the net inflow of water in the monitoring area is 80 cubic meters per hour, and the sum of the unit water volume data collected from...

Abstract

The invention relates to the technical field of pipe network leakage monitoring, in particular to a method and a monitoring system for establishing a multi-channel water supply structure leakage monitoring pipe network. The present invention includes step 1: delineate a plurality of different monitoring areas; step 2: divide metering nodes; step 3: connect all metering nodes in each monitoring area to the water supply network unit where they are located; step 4: provide Install smart remote water meters in the monitoring area; Step 5: Set up monitoring devices for each monitoring area to monitor pipeline leakage in the corresponding monitoring area; Step 6: Collect net inflow water data; Step 7: Sum and total of water consumption data Inflow water data are compared to determine whether there is water balance. The invention is used for finding the leakage situation of multi-way water inlet pipe network and locking the leakage position.

Description

technical field [0001] The invention relates to the technical field of pipe network leakage monitoring, in particular to a method and a monitoring system for establishing a multi-channel water supply structure leakage monitoring pipe network. Background technique [0002] The urban water supply network is an important infrastructure. With the development of the city, the urban water supply network system is becoming larger and more complex. In the process of use, the water supply pipe network often leaks due to some man-made or non-man-made factors, and many leaks are hidden and difficult to be discovered by people. If the leak is allowed to affect the health of residents Water is safe, and in the long run it will cause a great waste of water resources. [0003] However, in the face of the increasingly complex water supply pipe network system in today's society, the existing methods for monitoring leakage, especially in the case where there are multiple water supply plants ...
