Abstract

Disclosed is a control system for a water network. The control system includes a plurality of remotely-located monitoring and or monitoring and automatic control stations each including an automation controller for local control and automation, and each in communication via a dual-ring communication topology for system or wide-area control. The dual-ring facilitates redundant peer-to-peer data exchange to provide upstream and downstream water flow and water quality information. Systems described herein may calculate flow differential based on water flow data from each of the monitoring stations, and control flow based on the calculated flow differential.

First claim

What is claimed is:

a plurality of flow sensors, wherein each flow sensor measures flow data of one of the plurality of water channels;
a plurality of flow monitoring stations, wherein each flow monitoring station is associated with one of the plurality of water channels to receive flow data from an associated flow sensor and transmit control signals to an associated adjustable gate,
wherein one of the flow monitoring stations serves as a flow control station to receive flow data from and transmit commands to others of the plurality of flow monitoring stations; and

a dual-ring redundant communications network supporting two different protocols, comprising:
a first communication ring that connects each of the plurality of flow monitoring stations in a ring topology that facilitates communication via a bi-directional peer-to-peer communications protocol, and
a second communication ring that enables the flow control station to transmit commands to others of the plurality of flow monitoring stations via centralized client-server communications.

2. The system of claim 1 , wherein each of the plurality of flow monitoring stations comprises:
a first radio with a first peer-to-peer communication channel and a first client server communication channel for communication via both the first and second communication rings in a first direction on the dual-ring redundant communications network; and
