1. **Monitoring system.
The monitoring system in smart water affairs is based on network monitoring technology and supported by the monitoring center to provide information of various monitoring sites for the flood control early warning and monitoring decision-making system. In the urban public monitoring, the monitoring of main roads and low-lying areas in urban areas is fully supplemented, and the monitoring systems of multiple platforms and departments are shared, and representative monitoring points are selected in combination with the urban hydraulic model.
2. Integrated drainage command and dispatch system.
The integrated drainage command and dispatch system in smart water is a visual management system, which uses professional model software to simulate tests, set up corresponding command and dispatch authority, and communicate with the system and social security platform.
Subsequently, various information technologies were used to realize the establishment of the perception layer and the execution layer. RTU is set upstream of sensor communication in the perception layer, and RTU or industrial router (with SIM card) is installed upstream of the actuator communication of the execution layer. Depending on the operating conditions, the sensors and actuators can be optionally matched to GPS.
Sensory layer layout. Pipe networks.
The main nodes of the drainage main pipe are equipped with flow meters and pressure gauges.
Install flow meters for drain mains and drain pipes.
Set the flow meter and level gauge of the overflow well.
Flowmeter and turbidity meter are installed in the interception well.
The flow meter and pressure gauge are installed in the outlet pipe of the water pump.
3. Flowmeter, turbidity meter and water quality testing instrument are installed at the sewage outlet of the sewage treatment station.
Rain gauges are set up in the catchment area.
Flow meters and level gauges are installed in the waterways.
Level gauges are set in adjustment pools, regulating tanks, sinks, wet ponds, and wetlands.
Monitor the main roads and low-lying areas of the city.
4. Execution layer configuration.
Sink-type gate hoist. Electric actuator for intercept wells.
Pumping station PLC control cabinet, sewage pumping station.
Rainwater pumping station PLC control cabinet.
PLC control cabinet of reclaimed water pumping station.
Set up the opening and closing mechanism of the sluice, such as regulating pool, regulating pool, water tank, wet pond, wetland, etc.
Road ** surveillance.
Based on time and space information, the integrated drainage command and dispatch system in smart water fully applies a new generation of information technology such as perceptual monitoring network, Internet of Things, cloud computing, mobile Internet, industrial control, and hydraulic model to the municipal drainage operation conditions, and completes the comprehensive perception of the urban drainage operation conditions through "one map".
