Description
Technical field
This utility model relates to detection and the safe operation field of water-supply systems, is specifically related to a kind of for city confession
The soil's rigidity circuit of the underground metal pipes of water.
Background technology
Water system ensures the domestic water in city, water for industrial use and other is with the regular supply of water, is modern city
Life.For a long time, China's Urban Underground water supply network leak rate is the highest, and the substantial amounts of water seepage by underground pipe network is made
Become the huge waste of water resource；Pipe network model causes unstable " secondary pollution " with sudden change, water quality inferiority and pipe network of pressure of supply water etc.
All affect common people's daily life；Groundwater supply pipeline leakage can be taken away a large amount of silts, is formed and subsides in a large number, constitutes substantial amounts of
Hidden dangers in project.As can be seen here, groundwater supply pipeline leakage causes a large amount of economic loss, and life and safety in production to city all carry
Carry out huge potential safety hazard.
City supply water pipeline is buried in underground, bad environments, and its soil's rigidity technology is the most perfect, to water supply line leakage loss
Timely detection and location, maintenance and safe operation bring the biggest difficulty.Traditional water supply network soil's rigidity method has passively
Maintenance method and audition method.Passively maintenance method just carries out a kind of method overhauled after being the bright leakage of discovery.The leak detection of audition method is to utilize ground
Lower pipe leakage produces sound and taps water pipe, estimates on ground whether pipeline leaks, estimates the one side at small opening position
Method.The major defect of audition method leak hunting method is: (1) sound sometimes is big, hears that the scope of the sound is excessive, it is difficult to determine correct
Leaking area；(2) sometimes leak and be not necessarily leak source at the sound, rely primarily on the experience of people's long term accumulation；(3) numerous in traffic
The area busy, noise is strong, audition method is difficult to normally work；(4) some sound is too small, is also difficult to detect by audition method.Although it is existing
Based on audition method, the technology having carried out many improvement, instrument performance and operator improves constantly, but still suffers from the biggest
Limitation, particularly automaticity is low, and noise is excessive, when piping laying is crossed deep, infers pipeline whether leakage loss the most very
Difficulty.

Work process
First, 555 intervalometers produce the pulse signal of certain frequency, be input to the two or three through the 7th ceramic condenser C7
The base stage of pole pipe Q2 turns it on, and after the second audion Q2 amplifies, is the formation of the arteries and veins that frequency stability is high, power is bigger
Rush signal input.It is then input in the second inductance L2, the electric current that generation moment is stronger in coil, so that producing around coil
Raw constant alternating magnetic field.The magnetic field intensity that the magnetic field produced can be gathered by linear hall sensor UGN3503U and will sense
It is changed into voltage signal to linearly.Through being capacitively coupled to the in-phase input end of the first operational amplifier LM324A, will suddenly
The voltage that your sensor obtains is converted to voltage-to-ground.Through the coupled electric capacity of signal that the first operational amplifier LM324A amplifies
11 ceramic condenser C11 are input in rear class peak-detector circuit.Peak-detector circuit is made up of two-stage calculation amplifier, and second
The peak value of input signal is delivered on the 12nd ceramic condenser C12 by operational amplifier LM324B, and remains behind.3rd computing
Amplifier LM324C forms buffer amplifier, output is come with Capacitor apart.By peak detection and rear class Hyblid Buffer Amplifier electricity
Road, is amplified to the DC level of 0V-5V by the small-signal collected.Then, the DC analogue quantity after amplification turns through modulus
After die change block, be converted to digital quantity and be input in control chip MSP430f149, according to the detection data collected with set
Definite value compares, and can analyze the exact position of pipe leakage and the substantially degree of leakage loss, it is also possible to judge this underground, region gold
Belong to wear condition and the possible degree of assessment generation leakage loss of feed pipe.When measurement result shows that at this, metallic water pipe leakage loss is serious
Time, the second LED 2 can constantly flash, and buzzer BELL can send the police of different frequency according to leakage loss degree
Report sound.
