Qingyuan Waterworks Project: Automated Control Systems Overview
Water Intake Control
Auto pump start/stop: Uses water level sensors to prevent source depletion or pump idling.
Flow regulation: PLC adjusts pump speed/valve openings to match varying supply demands.
Water Treatment Control
Coagulation & sedimentation: Auto-adjusts coagulant dosage (based on turbidity/flow) and schedules sludge discharge.
Filtration: Triggers backwashing (by pressure/time) to maintain water quality.
Disinfection: Precise dosing (chlorine/hypochlorite) with residual chlorine monitoring for compliance.
Clear Water & Supply Control
Tank level management: Real-time monitoring adjusts inlet valves/pumps to stabilize levels.
Variable frequency pumps: PLC modulates speed via network pressure/consumption data for energy-efficient, constant-pressure supply; coordinates pump switching.
Pipe Network & Equipment
Monitoring & scheduling: Tracks pressure/flow at key points; alerts on anomalies (e.g., overpressure) and enables remote valve adjustments.
Fault handling: Real-time equipment monitoring (current, temperature) triggers alarms; auto-switches to standby systems during faults.
Data & Efficiency
Data management: Records water volume, quality, and equipment data for trend analysis.
Energy optimization: Adjusts equipment operation (pumps, fans) by demand peaks; uses algorithms (e.g., PID) to minimize chemical/energy waste.
