Abstract
The present invention is the intelligent checking system of a pipe network water leakage.It include: that all pipe network table notes are built into, Intelligent pipe net system.It recording exceptional information and is reported when table document.Exception information is extracted in the analysis of background intelligent analysis system, passes through algorithm Accurate Analysis leak place.Alarm work order is generated in real time.Can solve public supply mains leakage point can not orientation problem, reduce pipe network water leakage bring loss.
Description
Technical field
The present invention relates to the leak water detdction technical fields of intelligent water utilities pipe network, more particularly to are accurately positioned the pipe of leaking area
The intelligent checking system of net leak.
Background technique
Wisdom water utilities pipe network water leakage is a global problem, and especially in some African Territories, leak ratio may reach
To 30%-50%.
At present the active leakage monitoring method of mainstream have based on various kinds of sensors monitoring method and based on flow monitoring
Two kinds of method.
Method based on sensor monitoring: artificial using the equipment monitoring for having sensor or while disposing pipeline
Key position installs various kinds of sensors on pipe network, and the hydraulic pressure, flow at each position, vibration on pipe network can be predicted in control room
Amount accumulates the normal amount in pipe network operation and storage, once there is abnormal generation, i.e., traceable recourse, so that accident point is found, it is preceding
Person needs a large amount of manpowers, and precision is not high, and the latter needs additional deployment large number of equipment, both can only judge whether there is leakage
It loses, and cannot judge the size of leakage.As most by common sound and vibration method because the sound that issues of leakage not with the size of leakage
Directly proportional, sometimes negative correlation instead is missed bigger, sound is smaller.So detecting leakage in this way
Afterwards, can not judging the leakage, whether it is necessary to carry out trenchless rehabilitation.
Leakage monitoring method based on flow monitoring:
Existing scheme: in a certain region of water supply network, the flowmeter in this region will be entered and flow out the flowmeter in this region
Statistics control, difference must be this section without metering loss, if knowing the leak damage in this section without other no stoichiometric consumptions
Consumption, this " knows what's what " to manager's meeting.It is closeer to fill table cut zone, segmentation is clearer, then understands the case where each section of leak
Also clearer.But dress table can not be excessively intensive.This method not can determine that leakage point accurate location, therefore cannot function as specific
Repair, break the foundation on road surface.
Summary of the invention
In view of this, it is an object of the invention to propose a kind of intelligent checking system of pipe network water leakage, it can be targeted
Ground makes up the shortcomings that existing method, improves leakage loss monitoring efficiency and cost.
The technical solution of the present invention is as follows: a kind of intelligent checking system of pipe network water leakage, comprising:
1. the daily flow of each node is calculated in existing Lay great mansion water utilities system-based (all table notes can monitor pressure, flow),
2. calculate daily each node and its direct child node flow and between error.
3. there are leaks if there are significant errors.
4. then calculating whether each child node has leak by the same method if there is leak, judge that leak is by some
Caused by child node or this node and the pipe network of child node have leak.
5. if determined which section pipe network there are leaks simultaneously there are leaks by calculating each child node pressure loss for the node
Calculate leaking area.
Calculation formula are as follows:
Water loss/time=unit water loss=q3* breakage size * loss coefficient (being determined according to duct size)
So:
So final formula are as follows:
Learn that pipe diameter size is 25 according to many experiments testIt is 30 for 302.44, pipe diameter sizeFor 522.3,
6. survive automatically if there is leak alarm and task.
7. worker carries instrument and handles leakage accident.
Detailed description of the invention
Fig. 1 is leak water detdction flow diagram.
