Description
Technical field
The present invention relates to plumbing field, be specially a kind of novel water supply network leakproof monitor and detection technology.
Background technology
For urban water supply, municipal water supply and community secondary water-supply, metering is a kind of leakage loss control mode all comparing at present accreditation at home and abroad, but due to the difference of the national conditions such as pipeline distribution, geographical position, the different local mode implemented is distinguished to some extent.Our widely used traditional leakage loss control mode, be based on ultrasonic wave principle, by the detection to pipeline leakage sound wave, the leakage loss control work carried out, this is a kind of passive means.Although can play a role, because this passive mode can not find leakage loss point timely, cause the time lengthening of leaking, increase leakage loss.Meanwhile, for this passive mode, no matter from manpower, time, efficiency cost, or by environment affect aspect, all can restrict manager and promote managerial skills.And the secondary partition management of our application now, be a kind of monitoring pattern of active, from the deficiency can improving traditional approach to a great extent.The implementing though of the main flow of current China water supply network secondary partition management is that the water supply network entirety in a region is divided into tens or even up to a hundred secondary partition management zones, then by the calculating to each secondary partition minimum discharge at night and actual used water amount, the true leakage loss water yield is drawn.This thinking is theoretically without any problem, but can find that this method operates in conjunction with China's water supply network national conditions is do not conform to reality.If need the true leakage loss water yield in calculating secondary partition, need the water supply volume of adding up subregion total water consumption and each water unit at one time, this means to need by subregion the water meter of useful water unit be replaced with remote transmitting water meter.With a citing of the secondary partition with water unit 5000 family, the cost of light replacing remote transmitting water meter will up to 500,000, and this input is unpractical.
Summary of the invention
Technical problem solved by the invention is to provide a kind of novel water supply network leakproof monitor and detection technology, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of novel water supply network leakproof monitor and detection technology, comprises data collection station, central control system, described central control system is connected with at least 2 data collection stations.
In the present invention, described data collection station comprises pressure sensor, flow transmitter and PLC module, and described pressure sensor, flow transmitter are integrated in PLC module.
In the present invention, described central control system comprises communication module, Website server and Engineering Service system module.
In the present invention, run in described communication module and have control software design.
The present invention proposes a set of from bottom to top, by mode qualitatively, obtain the water supply network secondary partition Managed Solution of maximum return with optimal cost.High-precision inserting-type flowmeter under secondary metering subregion key point installs low flow velocity additional, obtains the data of flow, pressure simultaneously with point, by night minimum discharge monitoring and analysis, obtain the minimum discharge curve at desirable night of secondary partition.From at this moment, manager can pay close attention to the situation of change of secondary partition minimum discharge at night every day, once the minimum discharge curve at actual night monitored occurs depart from more greatly and continue with minimum discharge curve at desirable night, can judge that the situation of burst water or newly-increased leakage loss appears in this secondary partition, Added Management person can make reaction and discriminatory analysis accurately timely to secondary partition leakage loss like this, and then the control implemented leakage loss level, reduce the loss.
In the present invention, by continuous practice, sum up a set of from bottom to top, utilize Internet technology to help client under the prerequisite of optimal cost, obtain the secondary partition quantitative model of maximum efficiency.Enforcement secondary partition manages, and manager can be helped to a great extent to promote the level of leakage loss control.
In the present invention, tap water pipe network secondary partition flow. pressure monitoring system is user is realize (being divided into two kinds: one is monitoring pressure, pressure early warning comprises later stage monitoring turbidity and chlorine residue to affiliated interior zone pipe network monitoring website; One is that monitoring flow controls).This project demand, at managing performance center, can be monitored each pipe network monitoring website of owning user; Monitor and forecast can be carried out to the website of affiliated N number of band valve; There is complete database, can add up historical data easily, inquire about and trend display; Control centre-each pipe network monitoring website all adopts wireless network (wireless network adopts GSM/SMS/PSTN/RF, and concrete quantity is determined according to actual conditions) as the transmission network of data acquisition and controlling.To intrasystem control substation, distant station, can increase easily and expansion, and connect smoothly with other plant equipment.
In the present invention, two_stage flow pipe network monitoring website needs monitoring ductwork pressure instantaneous delivery and integrated flux.Remote transfer signal is standardization GPRS signal or GSM signal, therefore selects a MULTILOG GPRS as data acquisition unit.Each pipe network monitoring station respectively establishes distant station a set of, is made up of remote controllers Winfluid system, carries out data transmission by GPRS equipment and control center.Total time of leaking is divided into three parts: the discovery time of Part I and leakage loss; The positioning time of Part II and leakage loss; Part III is the repair time of i.e. leakage loss.As can be seen from 11 pages of leakage loss situation maps we, in this three part-time, the discovery time of leakage loss, accounts for the nearly half of whole leakage loss time, and the discovery time therefore shortening leakage loss can reduce leakage rate to a great extent.Enforcement secondary partition manage, can quick lock in leakage loss occur region, greatly shorten the time of the discovery of leakage loss, manager made and reacts rapidly, and guide leak detection personnel to carry out the positioning work of leakage loss, accomplish object, have the soil's rigidity of emphasis.Set up secondary partition and manage the water quality deterioration that can help in water undertaking's prevention distribution system.When the border valve of closing some to isolate each secondary partition management time, fluctuating of current in pipe network can be reduced, thus the deposit that duct bottom accumulate is not easily by disturbance, minimizing water pollution.In addition, leakage loss is controlled, and leakage loss point reduces, and also reduces water quality at the contaminated probability of leakage loss point.
Beneficial effect: the present invention is integrated with pressure sensor, flow transmitter and PLC module, solving the pressure of secondary water-supply and flow can not the problem of early warning.
