Embodiment

[0022] A key point S5 in the water supply system of a small town is selected as an example for testing. The attached figure is a schematic diagram of the principle of the mathematical model of key control points.

[0023] 1. Parameter number

[0024] Select key node S 5 The 8 water quality and quantity parameters are used as detection indicators, including pressure, flow, pH, turbidity, oxygen consumption, iron, chloride, total hardness, and use the letter P respectively 5 , Q 5 , PH 5 ,Z 5 , COD 5 , Fe 5 , Cl 5 , C 5 .

[0025] 2. Data acquisition

[0026] The test was continuously monitored for ten days, and the sample was evaluated once a day, and the national standard method was used for determination. The data of online monitoring is shown in Table 1.

[0027] Table 1 Key control points in the water quality and hydraulic characteristics test table

[0028]

[0029] 3. Function assignment

[0030] 1) First determine the key node S 5 Whether the values ​​of the parameters monitored e...

Abstract

The invention discloses a multiple-water-resource key-point damage control and safe water supply method, and belongs to the technical field of urban water supply. In order to guarantee safe operation of a water supply pipe network system and prevent unexpected accidents, a mode recognition function of a network is utilized, key control points determined in the HACCP analysis are combined, factors like water quality, the water volume and water pressure are considered comprehensively and a multiple-water-resource key-point damage control and safe water supply technology based on a mathematic damage control model of key nodes is built. The method has the advantages of being capable of mastering the operation condition of a water supply pipe network in real time, fast and accurately diagnosing prospective faults, feeding back alarm information and reducing risks probably generated in the water supply production, processing and conveying processes of small-town water supply.

Description

Technical field [0001] The invention belongs to urban water supply management technology, in particular to a safe water supply method for controlling the hazards of multiple water sources and key points. Background technique [0002] The water supply system is an important infrastructure of a city, an important guarantee for social and economic development and people's lives, and it plays an important role in urban economic construction. With the improvement of social productivity, the continuous increase of urban population, and the continuous improvement of people's living standards, people's requirements for urban water supply systems are getting higher and higher. The scale of water supply systems continues to expand, and so does the complexity. How to realize safe water supply and information management of water supply system has become an urgent problem to be solved by urban water supply system. [0003] Artificial neural network is a nonlinear dynamic system that simulates ...
