A water quality safety monitoring and early warning system and method based on big data

Abstract

The invention discloses a water quality safety monitoring and early warning system based on big data. The system includes a water supply station distribution system, a water quality monitoring and early warning system, and a pipeline replacement information upload system; the water supply station distribution system is used to judge the water supply station according to the geographical location Distribution status; the water quality monitoring and early warning system monitors the water quality in the pipeline through the monitoring nodes set up to determine whether the water quality contains abnormal conditions; the pipeline replacement information upload system detects the change of residual chlorine in the pipeline water quality, after After the flushing of residual chlorine, it is analyzed whether it is necessary to replace the pipeline, so as not to affect the quality of the water in the pipeline. By adjusting the settings of the monitoring nodes, the power consumption for monitoring can be reduced, energy can be saved, and the water quality can be effectively monitored; The time is calibrated to ensure that the data time of the monitoring node cut-off measurement is synchronized to ensure the authenticity and validity of the data.

Description

technical field [0001] The invention relates to the technical field of big data water quality safety, in particular to a water quality safety monitoring and early warning system and method based on big data. Background technique [0002] Tap water has become an important source of human beings, and the country has very strict requirements on tap water flowing out of tap water plants. Strictly control the degree of bacteria or various microorganisms and mixtures in tap water to affect human health. Chemicals containing chlorine are usually used The medicament eliminates the bacteria in the tap water, but when the tap water flows out of the water plant, there is still more than or equal to 0.05mg of residual chlorine in the water to eliminate bacteria and slag in the pipe network, but with the integration of residual chlorine in the water, residual chlorine The gradual dissipation of chlorine in water will not be enough to eliminate the bacteria in the pipe network; therefore,...

[0003] In the paper "Rational Analysis of the Distribution of Water Quality Monitoring Points in Urban Water Supply Networks", published on January 15, 2012, it is stated in the paper that "the number of sampling points for water quality testing in the pipe network should generally be set for every 20,000 population of water supply population. The calculation of one sampling point...should be set at the point where residents often use water, so that large users of municipal water supply should be inspected, effectively avoiding the occurrence of missed inspections, and reaching the foolproof standard." The paper indicated that multiple inspections need to be set The sampling points collect the safety of water quality, but if multiple sampling points are used for monitoring, the power consumption during monitoring will be wasted, but if some monitoring points are closed, the safety of water use cannot be effectively monitored. Therefore, It is necessary to reasonably adjust and set the monitoring points; since the pressure of the water flowing out of the pump is uniform, the impurities in the pipeline will not flow with the water flow, but if the water pump is restarted for a period of time, the water flowing out of the pump will be affected. The pressure is greater than the standard pressure, which can flow the water and impurities in the pipeline together in the water, resulting in more bacteria and impurities in the water, and reducing the quality and safety of the water;
