Technical Field
The present invention relates to monitoring technology, and more particularly, to a monitoring system and method for a water distribution network.
Background
With the progress of times civilization, human life and production depend on the use of a large amount of resources, of which water is the most important resource. Modern life is no longer using various resources and energy sources, and no daily clothes, sports and recreation are closely related to water resources. In addition to the desire to achieve the most efficient utilization of limited resources and achieve economic benefits, the issue of effective utilization has been the subject of research efforts.
Most of the traditional water leakage management is very passive, and the purpose of leakage detection and prevention and control or the reduction of water leakage by reducing pressure at night is achieved by means of manual methods such as public reporting and periodic inspection, and the detailed description is as follows.
Ground-penetrating radar (GPR) is an apparatus for detecting and imaging conditions under the earth surface with radar pulse waves, performs a nondestructive detection method with microwave-band electromagnetic waves on the radio spectrum, and receives radar reflected waves caused by various object structures under the earth surface. The ground penetrating radar can be used in media such as rocks, soil, ice, fresh water, sidewalks and various structures. The ground penetrating radar can detect the substances, material changes, gaps, cracks and the like under the ground surface, and the water leakage problem can be repaired by finding the damage of the pipe section in a manual mode.
Infrared thermography is a manual and non-contact technique that measures infrared wavelengths in order to measure temperature from a certain internal distance. The thermal imager can display images with different temperatures in colors, can quickly and simply check the surface temperature through the images to identify the high or low temperature point area, and can reduce the temperature of the soil near the water leakage area due to water leakage, so that the area near the low temperature point is found to be a possible water leakage point.
A sound induction fixed pipe network leakage detection system is an advanced water leakage detection method and technology emerging in recent years, a fixed sound sensing device is installed firstly, data are collected at regular time and transmitted to a control center in a wireless mode, then a sound sensor is used for waiting for abnormal sounds to appear, the arrangement position of the sound sensor and the size and the number of the sounds are analyzed, the sound speed in a pipe section is calculated, and then the water leakage position is judged. The disadvantage is that it is expensive.
The water pressure management is an important measure for water leakage control, and the water leakage can be reduced immediately as long as the pressure in a water pipe is reduced, so that the pressure at the outlet of a pressurizing station is reduced, or the water pressure of a high-position distribution tank flowing into a pipe network is reduced by arranging a pressure reducing valve, so that the water leakage can be reduced immediately. Therefore, although the water pipe still breaks and the whole body of the water transmission and distribution network is not improved, the water leakage amount under the existing body is reduced, and the effect of the instant effect can be obtained, so that the water pressure of the water supply pipe still needs to be properly controlled before the water leakage rate cannot be greatly reduced and the water leakage point cannot be judged, the damage of the pipeline due to the excessive water pressure is avoided, the water leakage amount is increased, and the method is a method for treating symptoms and not treating the root causes.
With the evolution and development of computers, the internet and various information technologies, there are new transmission and distribution water network management technologies and equipments such as data exploration technology, intelligent water network analysis, various sensors, etc. The system detects and collects the past and present conditions of water flow, water quantity, pressure or temperature in a pipe section by utilizing information and communication technology, judges whether water leakage is possible or not by comparing the present and the past water flow, water quantity, water pressure and water temperature through data analysis and exploration technology, and reports and displays in real time through modern monitoring equipment and a mobile handheld device so as to reduce water leakage reaction time and water leakage quantity.
