Water quality monitoring real-time early-warning system

Abstract

The invention discloses a water quality monitoring real-time early-warning system. The system includes a frequency collection circuit, a frequency modulation feedback circuit and a filter transmittingcircuit. The frequency collection circuit uses a frequency collector J1, of which a model is SJ-ADC, to detect water resource environment measurement data signal frequency received by a ground center. The frequency modulation feedback circuit receives output signals of the frequency collection circuit from two paths, a first path uses a triode Q1 and a triode Q 2 to form a push-pull circuit to prevent signal crossover distortion, a second path sues resistors R2- R4 and capacitors C2-C4 to form a frequency selection circuit to screen out single frequency signals, finally, a frequency modulation circuit formed by a triode Z3, a triode Z4 and resistors R8-R10 receives signals of the two paths and carries out frequency modulation, the filter transmitting circuit uses an inductor L2, a capacitor C7 and a capacitor C8 to form a filter circuit to filter out signal clutters. The water resource environment measurement data signal frequency received by the ground center can be detected in realtime, and converted into a water environment monitoring platform early-warning correction triggering signal.

Description

technical field [0001] The invention relates to the technical field of data aggregation, in particular to a real-time early warning system for water quality monitoring. Background technique [0002] The state of water supply in the prior art is directly related to people's living standards and physical health. The sanitation of urban water supply has become a common concern for people. To ensure the quality of water supply, an effective monitoring and management system must be equipped, usually from water plants, municipal management network, secondary water supply and user terminals, arrange water quality sampling and monitoring points according to the water flow path of the main pipe, and measure water quality parameters (turbidity, PH, ammonia nitrogen, dissolved oxygen, permanganate, etc.) through water quality detectors or corresponding sensors Parameter) sampling, transmitted to the water quality monitoring server through the network, the water quality monitoring serve...
