Abstract

The invention relates to a method for managing urban water supply pipes. The method comprises the following steps: establishing a water supply pipe network geographic information system to monitor water flow data in a water supply pipe network; placing a sound sensor at each monitoring point of the water supply pipe network to collect noise values of the water supply pipe at each monitoring point in the normal state of the water supply network; calculating the leakage performance index in each pipe network region and the water resource abundance index in each pipe network region in the water supply pipe network, and determining the pipe network regions required to be treated; calculating the active leakage control operation cost and the lost water cost of each leakage point in the network regions required to be treated, and determining the leakage points required to be treated in the network regions required to be treated. The method has the advantages that the water flow data of the pipe network can be monitored, leakage conditions of the water supply pipe network are determined, and leakage treatment strategies are provided, therefore, occurrences of post-event remediation are reduced, and the water loss and the operation cost of the pipe network are lowered.

Description

A kind of city water service pipe management method

Technical field

The present invention relates to feed pipe monitoring technical field, be specifically related to a kind of city water service pipe management method.

Background technology

Water supply network leakage loss is a global problem, and according to bibliographical information, the average pipe network leak rate in the whole world (water yield of missing from pipe network is divided by supplying water inventory) is 35% at present. Therefore, for saving water resource, realize sustainable development, must reduce pipe network leakage loss. The reason that pipe network leakage loss occurs has a lot, as pipe main body breakage, pipeline junction breakage, conduit fittings (lock, valve, fire hydrant etc.) leak etc.

At present the leakage monitoring of pipe network system is often only relied on and checks the leak source that pipe explosion accident has occurred, after booster generation, then adopt remedial measures. But, conventionally occur before pipe explosion accident, having there is the long period in these leak sources, and has caused thus a large amount of water resource loss and economic loss. In addition,, once form pipe explosion accident, tend to the social influence that causes a large amount of water resource waste, economic loss even severe. Therefore, need to provide a kind of system and method that can realize effective management water supply network.

Summary of the invention

The object of the present invention is to provide a kind of city water service pipe management method, can monitor the water flow data of pipe network, determine the leakage loss situation of water supply network, and the processing policy of leakage loss is provided, thereby reduce the generation of afterwards remedying situation, reduced water loss and the operation cost of pipe network.

For achieving the above object, the present invention has adopted following technical scheme:

A kind of city water service pipe management method, is characterized in that, comprises the following steps:

(1) set up Water supply network geographic information system;

(2) water flow data in monitoring water supply network, this water flow data comprises data on flows, pressure data, noise data;

(3) sound transducer is placed in to each monitoring point of water supply network, in the time of water supply network normal condition, gathers the noise numerical value of the feed pipe of each monitoring point;

(4) according to described Water supply network geographic information system, noise numerical value and water flow data, calculate the leakage loss performance indications in each pipe network region in water supply network, and determine the leakage loss level in each pipe network region in water supply network according to described leakage loss performance indications, these leakage loss performance indications comprise the poor index of production and marketing, leakage loss reference index or infrastructure leakage loss index;

(5) calculate the abundant index of water resource in described each pipe network region, and determine according to the leakage loss performance indications in each pipe network region and the abundant index of water resource the pipe network region that needs processing;

(6) calculate active leakage loss control operation cost and the loss water cost of each leak source in required processing pipe network region, determine that according to the active leakage loss control operation cost of described each leak source the processing priority of each leak source is other, and determine according to the active leakage loss control operation cost of each leak source and loss water cost the leak source quantity that needs processing, thereby determine the leak source that needs processing in required processing pipe network region.

As shown from the above technical solution, city water service pipe management method of the present invention, can monitor the water flow data of pipe network, determine the leakage loss situation of water supply network, and the processing policy of leakage loss is provided, thus reduce the generation of afterwards remedying situation, reduce water loss and the operation cost of pipe network. Whole method step is simple and clear, is easy to realize, and can realize monitoring management for water supply network to greatest extent, avoids the waste of water resource, the stability of assure feed water pipe network water supply.
