Integrated Information Dispatching System in Water Conservancy Engineering.pdf

(1) System Structure

Integrated information dispatching system in water conservancy engineering is an integrated collecting and monitoring system designed to collect information from equipment in pump stations and brake stations along the water transfer routine. The system can be divided into four parts. They are the integrated information dispatching center, the communication networks, the integrated monitoring sub centers and the field control systems in the pumping stations and the field control systems in the brake stations.

The communication networks include not only the backbone network, but also the communication networks between pumping stations and brake stations, and inside the pumping stations as well.

(2) Requirements of Network

The backbone network of the integrated information dispatching system is a redundant optic ring network. The network may self-heal automatically within 300ms when default occurs on the optic loop to guarantee no breaks in the real-time data transferring between sub stations and the central station.

The rest of the networks are integrated transferring/accessing networks based on industrial gigabit Ethernet.

(3) Implementation

Industrial Ethernet switches such as SICOM6496 and SICOM6224 are employed in the backbone network for data transfer and collection.

Industrial Ethernet switches such as SICOM3024 and SICOM3000 are employed in ring Ethernet networks between pump stations and brake stations for device access.
