Description

A kind of wireless remote water leakage detection device and system
Technical field:
The present invention relates to pipeline monitoring field, be specifically related to the water leakage monitoring system on a kind of water supply network.
Background technology:
Water is Source of life, and in daily production and the life process, the water mankind that get along well are all the time keeping being closely connected.China is the serious poor country of a water resource, and per capita water resource is less than 1/4th of world average level, and Regional Distribution is extremely unbalanced, and resource lack of water and water pollution lack of water are the two big problems of pendulum in face of us.Therefore, reasonably developing and effectively utilize existing limited water resource is to be related to the whether cardinal task of sustainable development of national economy.
At present, China's water supply industry ubiquity pipe network seepy question, average damage by water rate about 20%, wherein leakage loss accounts for 50% of damage by water, some places pipe network seepy question even very serious, the water supply benefit that this has just reduced water undertaking widely also causes serious waste to water resource, some in addition have influence on people's ordinary production and life.
The pipeline leakage phenomenon has become the ubiquitous serious problems of water supply industry, the long-time water supply line of not getting rid of leaks, except waste water resource causes enormous economic loss, thereby the ground that also may endanger road, bridge and building construction causes catastrophic failure.
Since the last century the eighties, domestic most of Running-water Companies all pay much attention to the pipe network seepy question, and the specialty of having set up oneself leaks and detect troop, have also disposed the checkout equipment that leaks of some specialties.Yet Running-water Company does not reach desirable effect to the control of leaking at present, and this is because the means of leaking hunting that adopt are mainly used traditional leak detection method---sonic detection at present, comprises methods such as bibcock audition, road surface audition, correlation analysis, surface drilling.This method is located relatively effectively (microcosmic aspect) for concrete leak source, and for the control of leaking (macroscopical aspect) certain limitation is arranged, and reason is:
1, the pipe network reason that forms of leaking is complicated, external force effect, long neglected and in disrepair, and pipe network is aging, and factors such as temperature variation, variation in water pressure, land subsidence, corrosion all might cause pipe network to leak.So pipe network leaks and produces is uncertain, that is to say that it is all may take place that pipe network leaks whenever and wherever possible.Will which zone this just requires, and we in time grasp rapidly in the very first time, the existence of which section pipe network is leaked? in time establishment officer and equipment carry out the leak source location to the scene.And our most of Running-water Companies rely on existing equipment to be difficult to accomplish this point, and often when finding that ground sweat or sedimentation, hydraulic pressure just go leak detection when descending these phenomenons, at this moment pipe network may leak several days even tens days.If things go on like this, water loss is just very serious, so just is unfavorable for the macro-control of leaking.
2, because the tap water work of leaking hunting is a long-term and arduous job, rely on traditional means of leaking hunting to drop into a large amount of man power and materials, and work efficiency is lower.The personnel of leaking hunting have spent a large amount of time and efforts in some watertight at all pipe network work often, do not go in the concrete leak source location work and main energy is put into, and have so just influenced the work efficiency of leaking hunting greatly.
3, present, detecting instrument equipment and the technology of leaking both at home and abroad great majority adopt the principle of sonic detection---determine by the noise that the detection piestic water produces from the leak source ejection whether pipeline leaks and the position of leak source.The propagation of noise of leaking approach is divided into three kinds: propagate, propagate, propagate along water along soil media along tube material and tube wall.Along the prematurity still of water-borne noise detection technique, prior art mainly detects the noise of propagating and propagating along soil media along tube wall.The decay of this noise like is subjected to factor affecting such as leak source size, hydraulic pressure, tubing material, pipe length, caliber, soil media and the decay intensity difference, thus the noise that produces of the leakage point that has we be difficult to differentiate by the ear by the people.The leak source that has so just may be slipped---for example (,) the nonmetallic pipe leak source, from valve leak source far away etc., if these leak sources can not in time be detected, will cause no small water loss.
4, in above various reasons, in order to control leakage loss more effectively, we should go to consider this work of detection of leaking that testing is done as a systems engineering leaking from macroscopic view (in time finding seepy question rapidly) and two aspects of microcosmic (location leak source).
Because water supply line belongs to pressure pipeline, in case leak, owing to have pressure differential inside and outside the pipeline, so water can spill from leakage point with certain speed, produce at the small opening edge simultaneously and reveal frictional noise, and noise can be propagated to both sides by pipeline. this leakage generally has stability and chronicity, and after the decay of this noise sound wave through various propagation mediums such as soil, have certain frequency range, and the signal amplitude decay is big more during distance.This acoustic characteristic that leaks is the ultimate principle place that present underground utilities leak and detect and locate, so need long-term stability, accurately obtain bibcock sonic detection data, and can be to the long term data of single-point and the convergence analysis of multiple spot data, and because sensing point often is positioned at underground, installation and removal, and read operation all is not suitable for frequently carrying out manually-operated, and wiring inconvenience, so the needs design is a kind of can be self-powered, the convenient installation, and can data be sent back the probe node equipment of data processing centre (DPC) by wireless mode, only rely on the time of the self-powered several years of just working.Yet the transmission of wireless signals distance is a pair of contradiction with the requirement of power consumption, and present checkout equipment is only supported in-plant data data transmission, so need manual inspection pipeline collection every day data, has increased maintenance cost.
Therefore be necessary to design a kind of extremely low power dissipation, support the water supply network water-transmission line leak detection equipment and the system of remote-wireless communication simultaneously, the manual inspection that full substitution is present by way of hardware and software combination.
Summary of the invention:
The purpose of this invention is to provide a kind of wireless remote water leakage detection device and system, it can realize full-automatic unmanned automatic detection; Solve the power consumption requirement of detecting devices and the contradiction between the wireless communication distance, and, carry powered battery, can carry out the aqueduct checkout equipment of the remote loopback of data with this extremely low power dissipation that designs a kind of software and hardware combining; Be fixed on above the water-transmission line with absorption or alternate manner, and work automatically for a long time continuously; On the supervisory system of Surveillance center, show the situation of leaking of whole water supply network in real time, and the information of leaking can be sent to the portable terminal that the testing staff carries with visual means.
